    [0002] Procedure and device for the safe installation of a telescopic lighting tower.
    [0003]
    [0004] Field of the Invention
    [0005] The present invention falls within the field of means for the control of the conditions of installation, operation and assurance of structural safety and prevention of overturning in telescopic lighting towers, preferably transportable, with power generation by means of internal combustion engine.
    [0006]
    [0007] Background of the invention
    [0008] At present, the need for additional lighting or lighting, makes the use of autonomous lighting towers in numerous environments, from construction sites to public events, is widely extended. Given the functionality of these devices, most of them consist of a mast of greater or lesser length, typically telescopic, which is deployed to place the light source as high as possible and thus illuminate a larger surface.
    [0009]
    [0010] The safe use of a telescopic lighting tower requires the prevention of overturning in all conditions of use of the tower, to avoid material and / or personal accidents.
    [0011]
    [0012] In the design phase of a telescopic lighting tower, it must be ensured that the tower complies with current regulations regarding the prevention of rollover. However, although a good design of the telescopic tower is carried out, the rollover prevention can be compromised by the installation conditions of the tower base, the conditions of mast deployment and other factors external to the installation itself base. Some of these factors related to the installation of the telescopic tower directly condition the tipping moment.
    [0013]
    [0014] On the one hand, there are mechanical factors of the different parts of a telescopic lighting tower that can cause the tower to overturn:
    [0015] • Horizontality of the base elements of the telescopic lighting tower and the homogeneous distribution of load in the support elements of the telescopic tower.
    [0016] • Mast extension level.
    [0017] • Orientation of the luminaires that determine the effective surface facing the wind in certain operating conditions.
    [0018] • Degradation of the quality or resistance of structural elements of the tower.
    [0019]
    [0020] Also consider the conditions of the location of the tower that can affect its stability and generate the overturn:
    [0021] • Terrain characteristics, such as resistance and others.
    [0022] • Presence of obstacles in the field that hinder its good installation.
    [0023] • Sloping or sloping terrain.
    [0024] • Presence of objects or obstacles that compromise the extension of the mast.
    [0025]
    [0026] On the other hand, other external factors may indirectly condition the structural safety and / or cause the structure to overturn during the tower's use phase:
    [0027] • Environmental factors, wind, rain, ice.
    [0028] • Conditions of use and handling of the tower, impacts, blows, etc.
    [0029] • The surface facing the wind.
    [0030]
    [0031] Current systems solve the stability of the mast by indirect approaches, such as wind detection by anemometers or other sensors that retract the mast in case of unfavorable conditions.
    [0032]
    [0033] There are also different support systems to ensure stability or systems that, depending on the stability of the tower, adjust the height to work safely.
    [0034]
    [0035] However, there is no known existence of any system that ensures the correct installation of the base to inhibit the lifting of the mast if a correct support is not detected.
    [0036] Description of the invention
    [0037] The present invention relates to a device and a monitoring and control method that ensures the correct deployment and installation of the base support elements in a telescopic tower, so as to minimize the risk of tipping over.
    [0038]
    [0039] The device and method of the present invention solve the aforementioned problems, providing security in the installation of telescopic lighting towers with power generation by internal combustion engine. The invention can be incorporated into new production telescopic towers or adapt its installation to existing ones.
    [0040]
    [0041] A first aspect of the present invention relates to a procedure for the safe installation of a telescopic lighting tower, of the type that has a base, a plurality of support elements, a telescopic mast, at least one luminaire, and a motor Internal combustion The method comprises activating the internal combustion engine; unfold the support elements sequentially on a support surface; for each support element deployed, detect the correct support of said support element on the support surface by obtaining vibration measurements of the telescopic lighting tower and comparing said vibration measures with reference values corresponding to said support element; and enable the rise of the telescopic mast if all the support elements have been deployed and support correctly on the support surface.
    [0042]
    [0043] The vibration measurements preferably comprise acceleration measures in the horizontal axes. The vibration measurements can also comprise inclination measures in the horizontal axes, where said inclination measures can be obtained from the acceleration measures.
    [0044]
    [0045] The method may also include detecting, for each support element deployed, the deployment of said support element. Said stage of detection of the deployment of the support element can be carried out by obtaining vibration measurements of the telescopic lighting tower and detecting an increase in the amplitude and / or frequency of at least one of the vibration measures above a certain threshold for the corresponding vibration measurement. Alternatively, the stage of detecting the deployment of the support element can be carried out by one or more limit switches.
    [0046]
    [0047] In one embodiment, the method comprises checking the stability of the telescopic lighting tower with the support elements deployed by obtaining inclination measures of the telescopic lighting tower in at least one of the horizontal axes and checking that the Measured inclination values are within a range of stability.
    [0048]
    [0049] The method may comprise obtaining initial vibration measurements of the telescopic lighting tower with the collected support elements, and comparing said vibration measurements with reference values.
    [0050]
    [0051] A second aspect of the present invention relates to a device for the safe installation of a telescopic lighting tower, of the type that has a base, a plurality of support elements, a telescopic mast, at least one luminaire, and a motor Internal combustion The device comprises vibration sensing means installed in the telescopic lighting tower and a control unit configured to:
    [0052]
    [0053] - Obtain some vibration measurements of the telescopic lighting tower from the measurements captured by the vibration sensing means.
    [0054] - Detect the correct support of each support element, once the corresponding support element has been deployed on the support surface, by comparing the vibration measurements obtained with reference values corresponding to said support element.
    [0055]
    [0056] - Enable the telescopic mast rise if all the support elements have been deployed and support correctly on the support surface.
    [0057]
    [0058] In one embodiment, the vibration sensing means comprise at least one accelerometer configured to obtain acceleration measurements on the horizontal axes, and where the vibration measurements comprise said measurements of Acceleration in horizontal axes. The control unit is preferably configured to obtain inclination measures in the horizontal axes from the acceleration measures in the horizontal axes, and where the vibration measures comprise said inclination measures in the horizontal axes.
    [0059]
    [0060] The vibration sensing means are preferably installed in the telescopic mast. The control unit is configured to detect, for each support element deployed, the deployment of said support element. The control unit can be configured to detect the deployment of a support element by obtaining vibration measurements of the telescopic lighting tower and detecting an increase in the amplitude and / or frequency of at least one of the measures of vibration above a certain threshold for the corresponding vibration measurement. The control unit can be configured to sequentially deploy, by means of activation of drive means, the support elements on the support surface.
    [0061] The device or system of the present invention is capable of detecting the level of acceleration that the internal combustion engine produces on an acceleration sensor, analyzing it and comparing it with the acceleration levels that occur on the same sensor when resting on the ground each one of the base supports to determine the number of supports deployed and their contact with the firm.
    [0062]
    [0063] If it is determined that the supports have been deployed and installed correctly, the mast lift is allowed, while if there is any limitation in the deployment or contact with the ground, it is not possible to lift the mast.
    [0064]
    [0065] The device comprises one or more acceleration sensors, positioned in the telescopic lighting tower to detect acceleration in the system, and a control unit responsible for processing the data received from the acceleration sensor modules (lower sensor module, upper sensor module or any other integrated in the telescopic lighting tower), having the capacity to calculate values that determine parameters of safe operation of the telescopic tower, where the device is installed from the data provided by the sensors. These values include indicative, non-limiting, those corresponding to predefined thresholds or threshold values.
    [0066] The device and procedure of monitoring and control in telescopic towers of lighting that is recommended, provides multiple advantages over those currently used, it is noteworthy that with its application avoids the placement of sensors for the detection of extension of the supports and ensures the reliability of the set as there are no reading problems in the sensors.
    [0067]
    [0068] The incorporation of the device in the telescopic lighting towers object of the invention simplifies the installation of system wiring by not relying on signals obtained by external sensors.
    [0069]
    [0070] Another important advantage is that the operational safety of the equipment is ensured by not allowing the electronic control module to deploy the telescopic tower mast if the extension of the supports has not been carried out correctly.
    [0071]
    [0072] Brief description of the drawings

    [0079] Figure 4 shows, according to a possible embodiment, a flow chart of the procedure for the safe installation of a telescopic lighting tower, with the most detailed steps.
    [0080]
    [0081] Figures 5A-5D represent an example of the analysis performed in the monitoring and control of the installation of the base of a telescopic lighting tower with four supporting elements.
    [0082] Detailed description of the invention
    [0083] Figures 1 and 2 schematically show a telescopic lighting tower 1 incorporating the safety device according to the present invention. The telescopic lighting towers 1 to which the present invention is applied comprise a base 2, support elements 3 of the base (stabilizing supports, typically retractable arms), and a telescopic mast 4 responsible for holding one or more luminaires 5 at its furthest end to the base 2. The energy necessary for the operation of the telescopic lighting tower 1 is extracted by an internal combustion engine 6 housed in the base 2. A main controller, not shown in the figures, is controls the telescopic lighting tower 1.
    [0084]
    [0085] The base 2 of the telescopic lighting tower 1 incorporates an electronic control module or control unit 7 in communication with vibration sensing means 8 responsible for measuring the vibration of the telescopic lighting tower 1 caused by the operation of the combustion engine internal In one embodiment the control unit 7 may be integrated in the main controller of the telescopic lighting tower 1, so that the main controller is reprogrammed to perform the functions described herein of the control unit 7. In another embodiment, both they are separate devices, preferably connected and intercommunicated with each other (wired or wireless), although they could have autonomous and independent operation.
    [0086]
    [0087] The vibration sensor means 8 can be located at different points of the telescopic lighting tower 1; for example, in the embodiment shown in Figures 1 and 2 they are located at the crosshead of the luminaires 5. Said vibration sensor means 8 are preferably implemented by one or more accelerometers.
    [0088]
    [0089] Figure 1 shows the telescopic lighting tower 1 with the support elements 3 retracted, without resting on the corresponding support surface 9 (usually the ground or ground). In Figure 2 the support elements 3 are extended, in contact with the support surface 9. As illustrated in said Figures 1 and 2, the level of vibration depends largely on the state of the support elements 3, if they are in contact or not with the ground or the surface of support 9. The level of vibration is represented by waves, so that the greater the number of waves, the more mechanical vibration is transmitted to the elements of the telescopic lighting tower 1. Figures 1 and 2 represent the XYZ Cartesian axes, where Z It is the vertical axis and the X and Y axes are horizontal axes.
    [0090]
    [0091] In particular, by measuring the vibration caused by the internal combustion engine, it is shown that the support elements 3 of the base 2 vibrate differently depending on the number of supports and their condition, so that by analyzing the signals captured by the vibration sensor means 8 on the X and Y axes can determine the stability and correct installation of the base 2.
    [0092]
    [0093] A general flow diagram of the procedure 100 for the safe installation of a telescopic lighting tower 1, executed by the control unit 7 that receives signals from the vibration sensing means 8, for example from one or several, is shown in Figure 3 acceleration sensor modules. Figure 4 shows, according to a possible embodiment, a flow chart of the procedure 100 with some of the most detailed steps.
    [0094]
    [0095] The method 100 for the automatic control of the installation and assurance conditions of the rollover prevention comprises an initialization stage 110 and a monitoring and control stage 120 of the tower base installation.
    [0096]
    [0097] In the initialization stage 110, the starting 112 of the internal combustion engine 6 is produced, which generates the energy for the luminaires 5 of the telescopic lighting tower 1, with the support elements 3 collected. The control unit 7, using the measurements received from the vibration sensing means 8, performs an analysis of the initial vibration 114 that naturally generates the internal combustion engine 6 in the structure of the telescopic lighting tower 1. The vibration sensor means 8 are located in the upper part of the telescopic mast 4, but in its collected state, the telescopic mast 4, and therefore the vibration sensor means 8, can be considered a single vibrating element, which will be collected perfectly the natural vibration of the system. The location of the vibration sensor means 8 in the telescopic mast 4 collected, allows, given the existence of a distance between the vibration sensor means 8 and the internal combustion engine 6, a moment is generated that allows the vibration signal to be received in a more amplified way than if the vibration sensor means 8 were placed on the same internal combustion engine 6, thus perceiving better the variations that occur when making supports. However, it is also possible to arrange one or more vibration sensors at other points that can correctly characterize the phenomenon, in case other types of masts or structural solutions are used, whenever it is possible to determine the natural vibration of the system.
    [0098]
    [0099] As shown in the flowchart of Figure 4, the initial vibration analysis 114 comprises a measurement of the initial vibration 202 captured by the vibration sensor means 8 before the deployment of the support elements, when collected. With the engine started, 204 is checked if the level of vibration detected is within a threshold programmed in the main controller of the telescopic lighting tower 1 and set as suitable for the vibration of the base 2 (for example, as it is shown in Figure 4, if the vibration level is higher than a resting level), in which case we proceed to obtain at least one parameter that defines the initial vibration level. In the analysis of the initial vibration 114, acceleration measurements (eg amplitude and oscillation frequency) captured by the vibration sensor means 8 on the X axis and on the Y axis are taken into account, and the analysis can also be considered value of the inclination measured in the X axis and in the Y axis. The inclination in the X axis corresponds to the angular deviation in the longitudinal axis of the system obtained by means of mathematical filters from the vibration in the X axis obtained by the means themselves vibration sensors 8. The inclination in the Y axis corresponds to the angular deviation in the transverse axis of the system obtained by means of mathematical filters from the vibration in the Y axis obtained by the vibration sensors 8 themselves, implemented for example by means of a 2 axis accelerometer).
    [0100]
    [0101] In the example in Figure 4, 206 the vibration levels measured on the X and Y axes are compared with values stored in a table. The vibration levels may correspond to the vibration values measured by the vibration sensor means 8 or to levels assigned to said values depending on whether or not to exceed predetermined thresholds.
    [0102]
    [0103]
    [0104] Finally, 208 is checked if the initial vibration analysis is correct, for example if the measured vibration levels are within a set range, normally defined in the initial factory calibration. These values are analyzed for a certain period of time 216, once past which if it has not been successful it returns to the initial vibration measurement step 202.
    [0105]
    [0106] Once the initial vibration level of the base is defined, the deployment of the support elements 122, which will be carried out individually, one by one, is started. Thus, for example, in the flowchart of Figure 3 the deployment for the support element i is made, where i has been initialized to 1 (that is, the first support is the one that is analyzed first) previously in the step 116 of the initialization stage 110.
    [0107]
    [0108] For each deployment of a support element 3, an analysis is carried out to detect the extension or deployment of the corresponding support element 124 (ie the support element i). The extension of the support element 3 can be detected by a sudden variation in the amplitude and frequency of the vibration captured by the vibration sensor means 8 (eg one or several accelerometers or acceleration sensors), for example by measuring the vibration 220 produced during deployment and comparison 222 of the vibration levels in the X and Y axes (the vibration levels may correspond to the measured vibration values or to levels assigned to these values depending on whether or not thresholds are exceeded preset) with values stored in a table, as shown in Figure 4. This variation in the vibrations observed in the accelerometer corresponds to the arrival at a stop installed in the extendable end part of each of the n support elements 3 that they extend and settle on the support surface 9.
    [0109]
    [0110] Next, 224 is checked if the detection of the deployment of the support element is correct, for example by checking if the measured amplitude and vibration frequency values are within established ranges. If the measured value of the amplitude and frequency of the acceleration in the X and Y axes exceeds the thresholds defined as positive extension detection, the corresponding support element 3 is considered to have been deployed. If during a certain period of time 226 a positive check has not occurred, the existence of an error in the extension of the supports 228 and returns to the initial vibration measurement step 202.
    [0111]
    [0112] Once the extension of the corresponding support element is detected, the support 126 of said support element on the ground or support surface 9 is detected (that is, if the support element has not only been extended, but also supports adequately on the ground), which is done through a vibration analysis. In particular, it is determined by analyzing the variation in the amplitude of the vibration detected by the acceleration sensors with respect to the measurements obtained in the initialization stage. In particular, the vibration after the deployment 230 is measured and the comparison 232 of the vibration levels in the X and Y axes (the vibration levels may correspond to the measured vibration values or to levels assigned to said values depending on whether or not the set thresholds are exceeded) with stored values, generating a table based on exceeding the thresholds defined in the initial factory calibration.
    [0113]
    [0114] As indicated above, vibration measurement can include not only acceleration measurements on the X and Y axes, but also inclination measurements on said X and Y axes. Acceleration thresholds define, apart from a level of a rest (level 0), at least two levels of acceleration (level 1 and level 2), so that the effect on the vibration in each of the axes can be defined and form a unique pattern when the vibrations detected in the axes are combined X and Y.
    [0115]
    [0116] Additionally, in comparison 232 of the vibration levels, the inclination detected in each of the X and Y axes can be studied. Variations in the inclination values over the initial values that exceed the threshold values defined in the initial calibration at the factory, they serve as additional validation to the correct detection. This additional validation means that a correct installation of the support elements 3 on the ground generates a deviation from the angle at which the tower is located. This variation depends on the force exerted on the support surface 9, the support element 3 being deployed and the number of support elements 3 of the telescopic lighting tower 1.
    [0117] Finally, at the support detection stage 234 is checked if the support detection of the support element in the field is correct, checking whether the levels of acceleration (and optionally the inclination values) measured in the X and Y axes are within established ranges. If during a certain period of time 236 there has been no positive check, the existence of an error in the support 238 of the support element is determined and the initial vibration measurement step 202 is returned.
    [0118]
    [0119] The deployments of the support elements of the telescopic lighting towers 1 can be automatic (ie performed automatically by actuating means or actuators, eg a servo motor for each support element) or manual (ie manually deployed by an operator) . In the case of automatic supports, the angle of inclination in the X and Y axes can be defined to act as the maximum threshold of the actuator, while in manual deployment systems the angle serves as a validator of the process described above.
    [0120]
    [0121] Once the correct support of the support element has been detected, 128 is checked if all the support elements have been deployed. If any support element is missing to be deployed, individual deployment 122 of the following support element is proceeded and the detection of its deployment 124 and its correct support 126 are repeated, repeating the process until all the support elements have been deployed.
    [0122]
    [0123] It is important to highlight that for each support element the measured vibration levels (acceleration and / or inclination in the X and Y axes) are compared with those stored in a table and corresponding to said support element, taking into account the level of initial vibration measured in the initial vibration analysis stage 114. In addition, the vibration levels measured for each support element normally depend on the activation sequence of the support elements, so that for example in a tower with four elements of support {1, 2, 3, 4} the measured values of acceleration and inclination on the X and Y axes to be checked are not the same if an order of activation of the determined support elements is used (eg {4, 1, 3 , 2}) that if a different activation order is used (eg {2, 4, 1, 3}).
    [0124]
    [0125] Once all the supports have been correctly deployed, 132 can be checked if the stability criterion necessary for the telescopic mast 4 is met. This stability criterion is given by the fact that the base inclination values measured 240 on the axes X and Y are 242 within a
    [0126]
    [0127]
    [0128] stability range corresponding to thresholds considered safe and that can be defined in the initial factory calibration. This stability checking stage 132 may have been carried out instead in the detection of the support 126 of the last support element itself, if not only acceleration measures but also inclination measures are included in the comparison of vibration levels 232 on the X and Y axes.
    [0129]
    [0130] If the established stability criterion is met, and the supports have been correctly deployed, the control unit 7 allows or enables 134 the rise of the telescopic mast, for example by sending a control signal to the main controller of the telescopic lighting tower 1 or directly enabling, for example by actuating a switch, the motor supply that drives the telescopic mast 4 (not shown in Figures 1 and 2). Optionally, the device itself can even proceed to execute the telescopic mast climb. If the stability criterion is not met in a predetermined time, it is determined that the base 2 does not have the stability required to allow the deployment of the telescopic mast 4. In that case, the motor drive that deploys the telescopic mast 4 is inhibited.
    [0131]
    [0132] With respect to the monitoring and control stage 120 of the installation of the tower base, the monitoring procedure continues to be carried out during the operation of the telescopic lighting tower 1. If a variation in acceleration or vibration is detected during use read that exceeds a previously defined threshold, an alert signal is sent indicating a failure in the stability of the base 2, so that the main controller of the telescopic lighting tower 1 acts accordingly (eg lowering the telescopic mast 4, turning off the luminaires 5, issuing an alarm indication, etc.).
    [0133]
    [0134] An example of the analysis carried out in the monitoring and control 120 of the installation of the base of a telescopic lighting tower 1 with four supporting elements 3 {SUPPORT1, SUPPORT2, SUPPORT3, SUPPORT 4} is shown in Figures 5A-5D. where the deployment of said support elements 3 is carried out individually and sequentially, according to a certain preset order (for example, the first support element APOYO1 is first displayed, then the second support element APOYO2, then the third support element SUPPORT3, ending with the fourth support element SUPPORT4).
    [0135] A graph is shown in Figure 5A with the vibration measurements (acceleration and inclination on the X and Y axes) captured in time by the vibration sensor means 8 during the deployment of the four support elements 3 {SUPPORT1, SUPPORT2, SUPPORT3, SUPPORT4}. The boxes highlight the moments in which the extensions or deployments of each support element occur, with a sudden variation in the amplitude and frequency of the acceleration in at least one of the axes.
    [0136]
    [0137] For a better detection of the extension of the support elements, a low-pass filter is applied to the signals captured by the vibration sensor means 8 to eliminate the measurement noise and obtain significant and stable values. The filtered acceleration and incline signals are shown in Figure 5B. The blow produced in the extension of the support element can be easily detected in the signal filtered by that sudden change of acceleration, where there is an increase in amplitude and a change in frequency for a short period of time.
    [0138]
    [0139] Once the deployment 124 of the corresponding support element is detected, the support 126 of the support element on the ground is detected, since it may occur that the support element 3 is deployed but does not rest properly on the support surface 9 (for example, if base 2 is arranged on an inclined surface). For this, the values of the filtered vibration signals are analyzed and compared with reference values. In one embodiment, two acceleration thresholds (TH1, TH2) defining three acceleration levels are used for the acceleration signals on the X and Y axes:
    [0140]
    [0141] - A resting level, level 0, which corresponds to a resting situation, where the support elements are collected and the first (TH1) or the second (TH2) acceleration threshold has not been exceeded (in absolute value).
    [0142]
    [0143] - A first level, level 1, where the first acceleration threshold (TH1) has been exceeded (in absolute value) but not a second acceleration threshold (TH2).
    [0144]
    [0145] - A second level, level 2, where the first (TH1) and the second (TH2) acceleration threshold have been exceeded (in absolute value).
    [0146]
    [0147]
    [0148] The previously established acceleration thresholds (TH1, TH2) or inclination can correspond to absolute acceleration or inclination values, or relative values (eg acceleration or inclination increments / decrements) with respect to the values measured in the measurement stage of initial vibration 202 in the rest situation (with the support elements collected).
    [0149]
    [0150] In the case that only absolute acceleration and / or inclination values are considered, the initial vibration analysis 114 could be an optional stage, although the initial measurement is normally necessary since the original vibration levels could change in function of the ground where the machine is supported.
    [0151]
    [0152] Similarly, the stage of detecting the deployment of each support element 124 may be an optional stage, implicitly performed in the stage of detection of the support 126 of the corresponding support element. That is, if a succession of vibration levels corresponding to what is stored in a table is detected, it can be considered that the deployment was carried out correctly in the programmed order, without even detecting the deployment moment itself. Thus, if the following sequence of acceleration levels {0,0}, {0,1}, {1,2}, {2,1 is obtained by means of the acceleration measurements on the X and Y axis {Ax, Ay} }, {0,1}, corresponding to the table in the example of Figure 5D, it can be considered that the evolution of the acceleration levels is adequate and there has been a correct deployment and support of all the support elements. For these measurements, the transients produced by the deployment of the support elements must be discarded (since the deployment produces sudden changes in amplitude and frequency of acceleration). However, the use of the deployment detection stage 124 of the support elements helps to separate the events produced and thereby improve the support detection process 126.
    [0153]
    [0154] Alternatively, the detection of the deployment can be carried out using means other than those explained in the diagram of Figure 4. For example, the support elements can incorporate a sensor that detects the extension of the support element (eg a contact sensor or a end of stroke sensor). However, the use of the detection provided in the diagram of Figure 4, through the analysis of the vibration (sharp increases in the amplitude and frequency of the acceleration), has the advantage of not needing to use such sensors, simplifying the electronics of tower
    [0155]
    [0156]
    [0157] of lighting by replacing the limit switches of each support element 3 with a unique vibration sensor means 8.
    [0158]
    [0159] In other embodiments, a greater number of acceleration thresholds or reference values defining more levels of acceleration may be used, in order to obtain greater accuracy.
    [0160]
    [0161] The evolution in time is represented in Figure 5C, without considering the transitory state generated by the blow of the deployment of each support element (which has different peaks of enough amplitude that can exceed several thresholds at the same time), of the level of acceleration on the X axis and the level of acceleration on the Y axis of the filtered acceleration signals of Figure 5B, where the following is appreciated:
    [0162]
    [0163] - At rest (without any extended support element), both levels of acceleration correspond to level 0.
    [0164]
    [0165] - After the deployment of the first support element, SUPPORT1, the acceleration on the X axis remains at level 0, while the acceleration on the Y axis has changed to level 1 (that is, it has exceeded the first acceleration threshold at the Y axis, TH1Y).
    [0166]
    [0167] - Once the second support element, SUPPORT 2, is extended (the first support element APOYO1 is already extended), the acceleration on the X axis rises to level 1 having exceeded the first acceleration threshold on the X axis ( TH1X), while the acceleration on the Y axis changes to level 2 (that is, it has exceeded the second acceleration threshold on the Y axis, TH2Y).
    [0168] - When the third support element, SUPPORT3, is deployed (the support elements SUPPORT1 and SUPPORT2 are already previously extended), the acceleration on the X axis rises to level 2 having exceeded the second acceleration threshold on the X axis (TH2X ), while the acceleration on the Y axis changes to level 1 having decreased below the second acceleration threshold on the Y axis, TH2Y.
    [0169]
    [0170] - Finally, after the deployment of the fourth and last support element, SUPPORT4, (the support elements SUPPORT1, SUPPORT2 and SUPPORT3 are already previously extended), the acceleration in the X axis drops to 0 and the acceleration in the Y axis is maintained in level 1.
    [0171]
    [0172]
    [0173] Figure 5D shows in a table the values of the acceleration levels in the X axis and in the Y axis for the different permanent states (ie without considering the transitory state produced during the deployment and hitting of the support element) of the resting situation and after each extension of a support element.
    [0174]
    [0175] Although in the example of Figures 5B-5D only thresholds and acceleration levels are considered, the inclination values on the X and Y axis could also be considered to detect support 126 (for example, considering one or more thresholds or reference values that define two or more levels of inclination).
