    Point-to-point control system for lighting installations. A bidirectional communications system for the generation of a point-to-point remote control architecture in lighting installations. This is based on the encoding of the information to be transmitted in a sequence of several time-controlled switching cycles of the lighting equipment supply in accordance with a predefined protocol. This allows information to be sent to all or to a specific luminaire of an electrical line with which, for example, to configure the working mode or reprogram its memory with new operating patterns or inquire about its status. An electronic control unit is established, to be installed in the luminaires, capable of decoding information sent by means of several on and off pulses with a variable duration of time, which allow different commands to be interpreted sequentially and as a whole. addresses and data. A feedback system is also established in the communications structure through the reading of the electrical consumption of the lighting line; Each luminaire, endowed with the ability to regulate its level of ignition and, therefore, its consumption, can carry out different sequences of regulation of its operation, cycles of different levels of brightness and duration that can be detected and decoded by a energy consumption located at the head of the installation.

    [0002] Point-to-point control system for luminaire installations
    [0003]
    [0004] Object
    [0005]
    [0006] The present invention refers to a control and management system for lighting installations with the purpose of improving aspects of profitability and reliability thereof.
    [0007]
    [0008] State of the art
    [0009]
    [0010] In lighting infrastructures, the luminaires are grouped into power supply electric lines controlled by a common switch. In this configuration, a priori, there is no possibility to control or regulate the lighting level of each point of light, despite the fact that this capacity optimizes its energy efficiency by allowing all modern regulations to adapt lighting levels. required depending on the specific use that is given at any time to the environment of the luminaires such as traffic lights, influx of people ... Urban lighting installations are an infrastructure that represents in most European municipalities a very high percentage high energy consumption and any rational regulation of its use can mean significant economic savings and a reduction in CO2 emissions and light pollution.
    [0011]
    [0012] The interest in generating mechanisms for this purpose has promoted the development of different remote control systems that allow road lighting to be adapted to the different seasons or events that municipalities are experiencing; for example, the same lighting is not needed in a tourist coastal town in February as in August or it is a common requirement that you want to adapt the illuminance in certain streets according to the social events that may occur: Easter, Christmas, summer parties or employers.
    [0013] Along with these functional criteria, the high costs and complexity of the preventive and corrective maintenance programs required in these distributed facilities to ensure their proper operation lead to these control systems also having the ability to automatically detect any incident. or failure in the facilities to be able to correct punctual failures, reducing action times, or anticipate bigger problems.
    [0014]
    [0015] Methods for detecting luminaire failure have been known from patent applications such as CN102938963A, US20120001552A1 for equipment using both conventional and newer LED bulbs.
    [0016] The main difficulty is communicating this information to the control center, for which it is necessary to generate a bidirectional communication system that allows information to flow between the different elements of the system as described in ES2097300.
    [0017]
    [0018] These requirements make it necessary to convert each point of light into an intelligent unit where, together with the conventional elements incorporated in them such as ballasts, starters, power factor correction capacitors or modules for the conversion of power network parameters such as power supplies or “drivers”, control and / or communication modules are included to work in collaboration with the command center. This is the base architecture of the point-to-point control networks that have been developing over the last 30 years as reflected by different patents such as ES2050605, US5726644A, US5237169A or US5221877A.
    [0019]
    [0020] Faced with the notable subsequent development of electronic systems, the main line of research in these lighting installations has focused on evolving the interconnection of equipment using data buses that allow the exchange of information.
    [0021]
    [0022] The three models of buses that have prevailed in the market are: specific purpose electrical wiring lines, the use of the base of the power line to which signal modulators are added to encode information about it (PLC). "Power Line Communication") or radio frequency (RF) wireless communication systems:
    [0023]
    [0024] Specific wiring buses have become widespread in interior lighting installations, being known from ES2170556, CN101662863A, US5059871A and commercial standards in this sector: DMX, DALI or KNX. Outdoors their implementation is complex since they cannot cover large distances, the installation of additional wiring is expensive and complicated to integrate in many cases and, finally, they are sensitive to interference and to problems of induction of surges.
    [0025]
    [0026] PLC systems eliminate the need to include additional wiring since information and electrical power share the same channel. It was developed with basic applications that generate a current wave that is superimposed on the consumption current of the luminaires and is led, by the line itself, to an electronic equipment at the head of the line, which is in charge of decoding the information. The first transceivers were patented in the 1970s, US3967264, and new proposals have been developed in subsequent decades, US4815106, ES2070747. They have as main drawback that require adapters in each piece of equipment connected to the electrical network that allow packets to be sent and received. These are complex when working on voltages greater than 100 V. In PLC systems, occasional drops may occur due to electromagnetic noise and due to the attenuation of the signal of the carrier, there may be high latency or communication failure.
    [0027]
    [0028] RF systems include specific hardware communications management modules at each lighting point that allow creating a mesh network of nodes that connect the control center and each of the installation's light points. There are multiple implementations of this type of network, depending on how this network is organized or what frequency 2.4GHz of ZIGBEE is used or other frequencies such as the 433 MHz or 866 MHz open bands in Europe. Different solutions developed from the 1990s, US5726644 allow obtaining various bandwidths to handle different amounts of data and, conversely, transmission distances, US20180042087, US20180027359.
    [0029]
    [0030] Today's increasingly complex solutions combine several of these three basic proposals US2018177021 in a single system.
    [0031]
    [0032] By their very nature, each of these bus models requires, as a minimum, a specific hardware module for signal adaptation and processing and transmission protocols. Both PLC and RF systems, the complexity of their transmission channels, which act on complex media where they fight or compete against environmental uncertainties: available bandwidth, surges, lightning ..., imply a significant increase in the price of purchase and installation and configuration of each point of light.
    [0033]
    [0034] You can greatly reduce the cost and complexity of a point-to-point architecture using a low-voltage network that allows us to reach all points of public lighting, but instead of modulating the signal that is expensive and complex, use a procedure simpler, more reliable and less expensive: connect and cut the power of the electrical line in a controlled way and measure the consumption that we have in it.
    [0035]
    [0036] There are preliminary proposals to use similar mechanisms to send information to luminaires in a network, ES2566229 but, in this case, limited to a one-way communication model, without the ability to configure lighting equipment (it only allows changing a program between a pre-recorded set) And it can only broadcast globally without being able to discern to act on individual teams.
    [0037] Summary
    [0038]
    [0039] The present invention seeks to solve one or more of the drawbacks set out above by means of a point-to-point control system for luminaires as specified in the claims.
    [0040]
    [0041] The point-to-point control system of public lighting equipment with bidirectional communication, under a protocol that encodes information and avoids packet collisions with differential control of access to the medium, through switching sequences of the power supply network and the capacity of each luminaire to modify its energy consumption instantaneously, where the control system comprises an electronic head controller that manages the transmission of data packets to and from a plurality of final electronic controllers that can be assembled in the corresponding lighting equipment; where the controller of the control panel and the controllers of the luminaires are interconnected through the electrical line of the lighting installation.
    [0042]
    [0043] The headend electronic controller measures and counts sequences of time sections as a base element for encoding the information to be transmitted through the generation of electrical pulses on the electrical line that reach the final electronic controllers through the corresponding power input.
    [0044]
    [0045] The headend electronic controller includes a lighting power line switch that supplies the electrical pulse trains.
    [0046]
    [0047] The electronic head controller is connectable to an electrical consumption meter through which information is received by reading the consumption variations in the lines of the lighting equipment caused by the variation in the emission brightness of the luminaires.
    [0048]
    [0049] The final electronic controllers assembled in the lighting equipment that act as nodes within a point-to-point architecture managed by the electronic head controller through the lighting power network; they have the ability to discriminate and interpret sequences of power pulses on the power line with information sent by the central control unit.
    [0050]
    [0051] The final electronic controller receives the information that includes configuration data of the luminaire such as communication points, choice of an operating mode, programming of new work sequences, asking questions about the status of the luminaire or transmitting information from additional systems that can be connected to the network. electric lighting as sensors of different environmental variables.
    [0052]
    [0053] The final electronic controller comprises a non-volatile memory capable of storing, maintaining and modifying the information necessary to configure the communication processes, the work routines of the luminaires and the status variables that collect the operating mode of the latter.
    [0054]
    [0055] The luminaire control unit has the ability to act on the luminaire's auxiliary equipment to modify the mode of operation of its associated luminaire at all times so that the brightness level and power consumption can be set instantly this.
    [0056]
    [0057] The luminaire control unit executes different transmitted and selected work sequences that adjust the installation to the needs of the environment, improving its energy efficiency and generating specific point sequences for sending information from this luminaire to the central bedside control unit.
    [0058]
    [0059] The control system for two-way communication luminaires, with the ability to modify and reprogram the parameters of the luminaires and in response to questions about their operating status, allows you to configure their operating modes, programming and establish acknowledgments of their status or operating mode without needing to have a specific communication bus for it.
    [0060] The control system comprises a control unit that supplies an on and off pulse sequence system that allows specific information to be transmitted to all the luminaires or to predetermined luminaires within a lighting line and, at the same time, receives information from the elements electrically connected to the lighting line as luminaires, sensors, etc. by means of the synchronized variation, according to a plurality of different patterns or time steps, of their consumption. These variations in consumption can be read and discriminated by a power meter located in an electrical panel electrically connected to the control unit.
    [0061]
    [0062] This central control unit allows not only to modify the operating mode of a luminaire but to change its internal programming adapting it to new unforeseen situations or new functional requirements due to new installation specifications and to generate a feedback channel with which to obtain remote information of the operating status of each of the lighting equipment on a line where this new system is integrated.
    [0063] The control system allows road lighting to be adapted to the different seasons or events experienced in the municipalities. With this, not only is the rational use of this type of facility optimized, reducing CO2 emissions and light pollution; It is also related to the vital importance that these facilities have when forming the perception of urban quality of the citizens.

    [0065] Brief description of the figures
    [0066]
    [0067] A more detailed explanation of the invention is given in the description that follows and is based on the attached figures.
    [0068]
    [0069] Fig. 1 shows a diagram of a lighting installation comprising: a control panel, an electrical wiring network and a set of light points associated with the line in any connection topology. In the first and last element of this list, the control system modules that generate a point-to-point control architecture are incorporated.
    [0070]
    [0071] Fig. 2 shows a functional diagram of each unit that makes up these facilities according to Figure 1, where the specific modules of the control system are identified and detailed for their proper operation and integration with the essential basic elements according to the installation regulations. current electrical.
    [0072]
    [0073] Fig. 3 shows a time diagram of a sequence of commutations generated in the supply network by the control system that sends a communications package to the luminaires, identifying different elements of a protocol: synchronization, addresses, commands, data, etc. to configure, reprogram, and interrogate by states and operating modes all or some luminaires in the line.
    [0074]
    [0075] Description
    [0076]
    [0077] In relation to Figures 1 to 3 where a point-to-point lighting control system is shown that configures a bidirectional communication mechanism between a central control unit - which acts as the communications manager - and each of the light points independent that make up a lighting installation. Each of them acts as an independent element capable of receiving instructions and answering status questions.
    [0078]
    [0079] The functionality of this communication mechanism allows to configure in a general way the network of luminaires or specifically each one of the equipments that form it. Possible actions include selecting work modes, reconfiguring these operating modes, establish the parameters that define the luminaire as a communication point or establish queries on the operating status of each lighting equipment. In this way, the installation's working mode can be configured optimizing energy consumption; allowing to save the maximum that each context allows (season of the year, use of the road, festivities, works ...) and cover all the parameters that define a point-to-point control system that allows:
    [0080]
    [0081] • Establish this configuration with all the luminaires together but also individually with each one of them
    [0082]
    [0083] • Question each luminaire for its operating status
    [0084]
    [0085] • Change the operating modes and configuration of each unit in the field regardless of the parameters programmed in the factory.
    [0086]
    [0087] The architecture depends on two basic objects:
    [0088]
    [0089] • A central point-to-point control device for lighting equipment with bi-directional data communication capabilities.
    [0090]
    [0091] • Electronic control units to integrate the luminaires in this point-to-point architecture
    [0092]
    [0093] The central control unit has the switching capacity integrated in the electrical panels of the electrical lines and the interaction with a power meter with which to supervise the installation, but also to receive information from its luminaires
    [0094] Luminaire control units must have the ability to count the time that elapses between receiving power and detecting the power drop in a shutdown process. Along with these two properties, an amount of non-volatile memory is also required with which to generate a state machine that stores and interprets, according to a pre-established common criterion, a consecutive sequence of consecutive power cycles of short duration, but controlled, deciding if they are the appropriate recipients of these commands, what actions to take if it is the appropriate receiver and executing the sending of a response if it is required. The information is divided into synchronization pulses, sending addresses, commands to receive and associated data.
    [0095]
    [0096] These control units are connected to the power supplies of the luminaires through the appropriate channels to be able to modify the light flow and the consumption of these lighting equipment. In this way, the control unit can execute the desired timed operation routines based on the instructions of the control system, but also generate cycles of variation of planned consumption that can be detected by the meter of the central unit and decoded to extract the significant information of each one of them.
    [0097]
    [0098] The proposed architecture assumes a system equivalent to a simple, reliable and affordable point-to-point control model (which facilitates its amortization and implementation). It uses the same basic components required by an installation remote control system based on electrical panels: contactors or electrical control switches and electric power meters and, in luminaires, control electronic ballasts or adjustable power supplies ( "dimmable drivers”) of them.
    [0099]
    [0100] Now referring to Fig. 1 where a basic public lighting installation is shown comprising a control panel 1, an electrical wiring network 2 and a plurality of light points 3. Different models of individual luminaires 4 can be interconnected.
    [0101]
    [0102] The control architecture has its central control element 5 of the point-to-point network installed in the control panel 1. As detailed in Figure 2, this element has one or more ignition control contactors 6 and shutdown of each existing 2 independent power line. The control unit is connected to these contactors to enable the equipment to be switched on in normal duty cycles, for example, overnight or to make short ignition pulses used to send meaningful information to the electronic control systems 7 installed in the luminaires individual 4.
    [0103]
    [0104] In this table, an electric power meter 8 is also located, with which instantaneous consumption measurements are obtained from each lighting line 2, with which you can have a global control of the energy expenditure of the installation, but also detect different small point fluctuations in consumption with which the luminaires 4 send information to the control center 5.
    [0105]
    [0106] The central control units 5 can be any model of electronic processor for specific use or a control system for lighting installations based on panel control, a system with less performance than point-to-point control.
    [0107]
    [0108] This equipment must have the capacity to interconnect with the required devices described: contactors 6 and electrical consumption measurement equipment 8; information processing capacity to encode the information to be sent by generating of sequences of time-controlled ignition pulses and decoding responses of luminaires detecting patterns of modification in the consumption of the network; and interconnectivity with a user control interface with which it is possible to determine modes of use, system configuration and receive incident warnings by the people responsible for the installation.
    [0109]
    [0110] The control units of the luminaires 7, in the same way, are electronic processors, with the common requirements of having a time counter capable of measuring several pulses of several seconds with which to control the time it is powered and the specific ones to have memory where to save the working modes that are marked for it and an output interface that allows you to control the brightness of your lamp 9 through your ballast, power supply or driver 10. This ability to act on the brightness of your point Light 3 allows you to execute the commands for the brightness requirements of the installation in a normal use mode and to influence with small cycles the consumption variation controller in specific sequences that the central control unit 5 can interpret as an information package using the power meter 8 as a receiver.
    [0111]
    [0112] Command sequences 11 include a set of power pulses 12 or cycles off 13 - on 14 - off 13 of line 2 of controlled times 15 that are received by all the luminaires 3 on the same line.
    [0113]
    [0114] Each of these pulses 12 must have a minimum width long enough not to be confused with a failed start due to the jump of some network protection system or that may be ambiguous for the receivers of the luminaires, being able to confuse two sections of consecutive discrete duration.
    [0115]
    [0116] Each feed pulse 12 can have associated different associated discrete states; each at incremental time slots of, say, 10 seconds. In this way there is a margin for error correction in the activation and cut-off time of the network or of the reading of the shutdown by the lighting control systems 7.
    [0117]
    [0118] In this way, if an ignition pulse 12 lasts between 10 and 20 seconds, a '1' data will be sent. If the pulse lasts between 20 and 30 s. The ‘2’ data is sent if the pulse lasts between 30 and 40 s. data ‘3’ will be being sent and so on until deemed necessary or convenient. According to this information coding sequence, sending a data of type to 1 ’nominally requires generating a 15 s pulse; one of type ‘2’ of 25 s ....
    [0119]
    [0120] A possible model of a communication protocol combining different pulses can have:
    [0121]
    [0122] • A specific first 16 cycle to start a communication process. Whenever a communication is received it is restarted, no other pulse of the communication can have this specific duration since it would cut the flow of this communication
    [0123]
    [0124] • A second pulse 17 to identify an address, which can be the individual address of a luminaire or an identifier for all to receive.
    [0125]
    [0126] • A third pulse 18 to identify a command among several possible action or communication actions
    [0127]
    [0128] • All the pulses from the first 19 to the last 20 that are necessary to send the data associated with that command
    [0129]
    [0130] A series of communication control procedures can be established as a maximum time for each pulse or a maximum number thereof so that a situation can be redirected where a communication is not completed correctly.
    [0131]
    [0132] Upon receipt of a data packet, one or more luminaires can carry out, under the control of their electronic systems of the point-to-point architecture (7), a cycle of brightness variation and its consumption that must be detected by the power meter 8 and interpreted by the central control unit 5.
