    description
    FIELD OF THE INVENTION The invention relates to a construction machine for carrying out construction work in the track area of an electrified rail network provided with a catenary. Further aspects of the invention relate to a server for receiving sensor data of such a construction machine and a system comprising the construction machine and the server.
    Background Construction work with construction machinery in the track area of a provided with a catenary rail network, the catenary must be usually turned off and grounded to prevent induction damage and personal injury. Nevertheless, it always comes back to such induction damage and accidents because construction machinery, especially construction cranes, get too close to live overhead lines or even touch them. Usually, a site supervisor is responsible to provide for the shutdown of the overhead line in the construction area concerned and to signal the leader of the construction machine that the catenary is switched off and / or grounded. Accordingly, the leader of the construction machine must rely on the information received from the site supervisor.
    If an accident or damage occurs, the problem often arises of unequivocally determining the exact causes of the accident.
    Summary of the Invention It is an object of the present invention to provide a construction machine of the kind set forth which increases safety for the operator of the construction machine in an efficient and simple manner and reduces the risk of induction damage. Another task is to improve the investigation of accidents and damage cases.
    This object is achieved in a first aspect of the invention of a construction machine for carrying out construction work in the track area of a provided with a catenary electrified rail network according to claim 1. Accordingly, the construction machine has a sensor unit and an output unit. The sensor unit comprises a sensor for measuring a voltage condition of the catenary, a Global Positioning System (GPS) module for detecting the position of the sensor unit and the associated GPS time and a radio modem for establishing a wireless connection to the Internet. The output unit is in particular a display unit and is provided for outputting the voltage state to the leader of the construction machine. The radio modem of the sensor unit is provided to transmit the voltage state of the overhead line, the associated GPS time and the associated position of the sensor unit via the Internet to a server coupled to the Internet.
    Such a system allows the operator of the construction machine to control the tension condition of the overhead line by means of the output unit. For this purpose, the output unit may be e.g. include a display on which the voltage condition of the catenary is displayed. This increases safety on the track construction sites and reduces accidents involving induction damage. In particular, can be checked directly on site in an efficient and reliable manner, whether the catenary has really been turned off. By using the Internet, a secure and reliable data connection can be established using the TCP / IP protocol family between the sensor unit and the server.
    The GPS module of the sensor device allows a safe and cost-effective determination of the position of the sensor device and thus the construction machine. By using the GPS time supplied by the GPS module as time base, the sensor data determined by the sensor device, in particular the voltage state of the contact line, can be provided with an exact and synchronized time stamp.
    The data sent by the construction machine to the server, in particular the voltage state of the contact line, the associated position of the sensor unit and the associated GPS time can be stored and evaluated by the server according to embodiments of the invention. The central storage in the server is particularly useful for the subsequent investigation of damage and accidents. The evaluation of the sensor data, in particular in real time, enables a control of the current operation and an immediate intervention in the current operation.
    According to an advantageous embodiment, the construction machine has a movable working arm and the sensor unit is arranged on the movable working arm.
    Such movable working arms are particularly vulnerable to reach in construction operation in the vicinity of the overhead lines. Movable working arms can e.g. Be arms of excavators, cranes and elevators. The sensor unit is preferably mounted at a position of the working arm, which usually reaches the highest working height during operation. According to an advantageous embodiment, the construction machine is a crane and the sensor unit is arranged at the upper end of a jib of the crane. This is the part that reaches the highest working height in a crane. By attaching the sensor at this point, the safety in crane work in the overhead line can be increased in an efficient manner.
    According to a further advantageous embodiment, the sensor of the sensor unit for measuring the electric field of the catenary is provided and the sensor unit is provided for detecting the voltage states «live», «grounded» and «off».
    Such a sensor that measures the electric field increases the safety of the measurement compared to sensors that measure the magnetic field. Thus, magnetic field sensors can only detect a magnetic field when an electric current is flowing. A sensor that measures the electric field can detect the electric field independently of a current flow. This also allows in particular the distinction between an off line and a grounded line. The catenary should i.D.R. Always be grounded, as even a switched-off line may pose a danger. Thus, e.g. If the line is switched off, it will be under dangerous voltage due to the influence of lines connected in parallel.
    According to a further advantageous embodiment, the construction machine on an acknowledgment button. Furthermore, the output unit is provided to request the leader of the construction machine to actuate the Acknowledge button, if the sensor unit detects the voltage state «live».
    As a result, the leader of the construction machine is explicitly pointed out that the catenary is live. By pressing the acknowledgment button, he must give a conscious confirmation that he has been informed of the danger. In addition, according to an advantageous embodiment, this confirmation is sent to the server and recorded there. According to a further advantageous embodiment, the working arm of the construction machine is blocked until the acknowledgment button has been actuated.
    According to a further advantageous embodiment, the sensor unit and the output unit are coupled by means of a bus system, in particular by means of a CAN bus system. Such a wired bus system enables secure and reliable communication. Alternatively, the sensor and the output unit could also communicate wirelessly.
    According to a further advantageous embodiment, the radio modem is intended to establish a wireless connection to the Internet via a mobile network.
    According to this advantageous embodiment, the entire network coverage and infrastructure of the mobile network can be used in an efficient and cost-effective manner. For example, the mobile network in Switzerland reaches a network coverage of 100% of all railway lines, so that a permanent and secure connection is guaranteed.
    In general, according to embodiments of the invention, all mobile radio networks can be used which have a corresponding network coverage and permit data transmission. In particular, according to embodiments of the invention, mobile radio networks according to the 2G, 3G and 4G standard including future generations can be used.
    According to a further advantageous embodiment, the radio modem is intended to establish a wireless connection to the Internet via a wireless local area network, in particular via a network according to the WLAN standard IEEE 802.11.
    This is a cost effective and reliable alternative, provided that a cover, e.g. with WLAN IEEE 802.11 exists.
    A second aspect of the invention relates to a server for receiving sensor data of a sensor unit of a construction machine according to the first aspect of the invention. The sensor data includes the voltage condition of the overhead line, the associated GPS time and the associated position of the sensor unit. The server is coupled to the Internet and intended to receive the sensor data from the radio modem of the construction machine via the Internet. Furthermore, the server is provided for storing and / or evaluating the sensor data.
    Another aspect of the invention relates to a system with a construction machine according to the first aspect of the invention and with a server according to the second aspect of the invention.
    Further embodiments, advantages and applications of the invention will become apparent from the further dependent claims and from the following description with reference to the figures.

    Short description of the drawings [0012]
    Fig. 1 shows a construction machine with a sensor unit for measuring the state of tension of a catenary of a rail network; and
    Fig. 2 shows a block diagram of such a sensor unit of a construction machine and a display unit of a construction machine, which indicates to the leader of the construction machine the tension condition of the overhead line.
    Way (s) for carrying out the invention Fig. 1 shows a construction machine 10, which is movably arranged on a track 11 as a rail-bound construction machine. However, according to other embodiments of the invention, the construction machine 10 could also be a non-rail construction machine that can be used outside the tracks. The construction machine 10 is designed as a crane and can be used to carry out construction work, in particular crane work, in the track area of the track 11. The track 11 is part of an electrified rail network and accordingly has a catenary 12, which is arranged as a catenary above the track 11 and provides a high voltage for the electric train traffic. The construction machine 10 has as a movable working arm on a boom 13 which is rotatably and pivotally mounted on a platform 10 a of the construction machine 10. At an upper end 13a of the jib 13 is a deflection roller 14, which is provided for deflecting a supporting cable 15. At the upper end 13a of the boom 13, a sensor unit 20 for measuring a voltage state of the contact line 12 is provided.
    The sensor unit 20 is shown in FIG. 2 as a block diagram. The sensor unit 20 has a radio modem 21 with an antenna 21 a for establishing a wireless connection 16 a with the Internet 50. In addition, the sensor unit 20 has a sensor 22 for measuring the voltage state of the contact line 12. The sensor 22 is preferably provided as a non-contact sensor for measuring the electric field of the contact line 12. This allows the sensor 22 to distinguish the voltage states "live", "grounded" and "off". The sensor 22 may be embodied, for example, as an electric field meter. According to another embodiment, the sensor 22 may use the principle of capacitance measurement to detect the electric field.
    Furthermore, the sensor unit 20 has a Global Positioning System (GPS) module 23. The GPS module 23 can communicate via the antenna 21a or also an additional, not shown, antenna via a wireless data link 17 with a satellite 18 and thereby determine the respective position of the sensor unit 20 and the associated GPS time. Finally, the sensor unit 20 also has a processor 24 and a data memory 25. The individual components of the sensor unit 20 are coupled by means of a bus system 27, e.g. via a CAN bus. In operation, the radio modem 21 establishes, via the antenna 21a, a wireless connection 16a to the Internet 50 and a data connection 16a, 16b according to the TCP / IP protocol family via the Internet 50 to a server 40. The wireless connection 16a to the Internet 50 can be made according to embodiments of the invention via a mobile network or via a wireless local area network, as long as a corresponding network coverage is available. The server 40 may e.g. be used by the site operator or construction site operator.
    The construction machine 10 shown in FIG. 1 also has an operating unit 30, which is arranged in a driver's cab 10b of the construction machine 10. The operating unit 30 can have a wide variety of operating elements and displays for the operator of the construction machine 10. The control unit 30 is shown in Fig. 2 as a block diagram in more detail. The operating unit 30 has a display 31 as an output unit or as a display unit. The display 31 is provided for outputting the voltage state of the overhead line to the leader of the construction machine 10. For this purpose, the display 31 may be an integral display of the operating unit 30, which also displays other information about the operating state of the construction machine 10 in addition to the voltage state of the contact line. The display 30 may also be a separate display, which is provided exclusively for the display of the voltage state of the contact line 12. In a simple embodiment, the display 31 may also be designed in the form of three LEDs, which are assigned to the three voltage states "live", "switched off" and "grounded".
    The operating unit 30 has, in addition to the display 31, a control panel 32 with control buttons or control buttons. In embodiments, the display 31 and the control panel 32 may also be combined e.g. be implemented as a touchpad. As a further output unit, a speaker 33 is provided, by means of which the leader of the construction machine acoustic information can be transmitted. The operating unit 30 also has a processor 34 and a data memory 35. In addition, the operating unit 30 has an acknowledgment button 36, which may also be integrated into the operating panel 32 in embodiments. If the sensor unit 20 detects the voltage condition "live", the operator of the construction machine 10 is informed by means of one of the output units, i. prompted by the display 31 or the speaker 33 to actuate the Acknowledgment button 36 and thus to confirm that he was aware of the danger of the live catenary 12.
    The individual components of the operating unit 30 are also coupled to one another with the same bus system 27 as the components of the sensor unit 20, e.g. with a CAN bus. In addition, the two bus systems 27 of the sensor unit 20 and the operating unit 30 are connected to each other in order to be able to communicate with each other and exchange data. The data exchange between the sensor unit 20 and the operating unit 30 can preferably take place via a wired connection laid in the construction machine. Alternatively, however, a radio link between the sensor unit 20 and the control unit 30 is possible.
    During operation of the construction machine 10, the sensor 22 of the sensor unit 20 continuously measures the voltage state of the contact line 12. At the same time, the GPS module 23 detects the associated position of the sensor unit 20 and the associated GPS time provided by the satellite 18. In addition, the GPS module 23 can also detect the speed of the sensor 21 and thus the speed with which the boom 13 is moved. The radio modem 21 then also continuously transmits the respective voltage state together with the associated position of the sensor unit 20, the associated GPS time and the associated speed via the antenna 21a and the data connection 16a, 16b according to the TCP / IP protocol family to the server 40. For this purpose, the sensor unit 20 at least transmits at least the voltage state of the contact line 12 to the display 31 of the control unit 30 and the current voltage state of the contact line 12 is the leader of the construction machine 10 displayed on the display 31. In addition, the further sensor data such as the position of the sensor unit 20, the GPS time and / or the speed could be transmitted to the operating unit 30, displayed on the display 31 and stored in the data memory 35.
