Description

The field of technology.

The invention relates to the field of electrical engineering and is intended for automated lighting, streets, highways and other objects.

The prior art.

A known system for monitoring and controlling illumination (patent for utility model RU 112572, IPC H05B 37/02, published January 10, 12). Illumination is controlled by creating temporary dynamically changing zones in the lighting objects.

The system includes the following elements: control units for illuminating the area, means for controlling and coordinating the illumination, interconnected with the light sources via wireless two-way communication.

The disadvantage of the system is the lack of dimming (brightness control fixtures) fixtures during the day.

Known automated dispatch control system for outdoor lighting (ACS NO) OM-SVET, developed by NPO Mir, Omsk (http://mirmsk.ru/asdu_no_omsvet., Accessed October 15, 2012). The system is designed for centralized automatic and operational dispatch control of lighting modes of streets, objects and territories of cities and settlements.

ACS NO OM-LIGHT is a multi-level system, built on a hierarchical basis and includes light sources, power supplies, a device for receiving and transmitting data, geographically distributed controlled supply points with controllers and communications. In the presence of electronic ballast control devices (electronic ballasts) installed in the system, the lighting can be switched on in the nominal mode (illumination level - 100%) or economical (illumination level - 50%). The disadvantage of the system is the impossibility of dimming the lamps in standalone mode, which leads to additional costs for the organization of communication in the lighting control system.

Known technical solution described in the application for invention 2013103659/07, 01/28/2013 (Published: 08/20/2014. Bull. No. 23).

This technical solution proposes a method consisting in autonomous adaptive dimming of street lamps during the day, depending on the length of daylight calculated for each day of the calendar year for a given geographical area, as well as traffic intensity.

The disadvantage is the average statistical approach to controlling the on and off time of the fixtures, which does not always exactly correspond to the actual outdoor illumination of the street and its traffic load at various night hours.

A known method of controlling the lighting devices of a vehicle is described in the patent of the Russian Federation No. 2364528 (12/25/2006, publ. 08/20/2009).

The method consists in receiving on a motor vehicle signals generated by a device for generating control signals for the operation of light devices of a motor vehicle located outside any of the motor vehicles, processing these signals in a signal processing unit mounted on the motor vehicle, generating, at the output of the processing unit, electrical signals received by the light vehicle devices.

Reception and transmission of auxiliary, control signals can be carried out via a radio channel, and radio transmitters located outside the vehicle can be located on street lighting poles, road signs, bridges and other objects. Passing by these low-power and short-range radio transmitters, radio signals are received in the car and with their help signals are generated that ensure the optimal mode of operation of the headlights.

The disadvantage of this system is that cars that are not equipped with devices cannot receive signals that optimize the headlights.

A known method of preventing blinding of drivers of vehicles and a device for its implementation, described in the patent of the Russian Federation No. 2578828 (07/16/2014, publ. 03/27/2016. Bull. No. 9).

The method consists in installing radio receivers and radio transmitters on vehicles. Radio transmitters broadcast coded signals on the air to remotely eliminate the dazzle of high-beam headlights if they are turned on in vehicles that are closer than a certain distance. The power of the radio transmitters and the sensitivity of the radio receivers determines the distance of such interaction of the glare prevention systems.

Due to the exchange of such radio signals, all cars enter safe mode when only low-beam headlights are turned on, which reduces the likelihood of dazzle from the main beam headlights in any road, weather conditions and for any number of cars.

The described method and device for its implementation may also contain additional channels for receiving telemetric signals from various sources along the roads. The system is functional when installing such devices on all vehicles.

Brief Description of the Drawings

In FIG. 1 a), b), c) shows a segment of a street or track to explain how it is illuminated using a one-way radio channel between cars moving along it and control units for the operation of street lighting fixtures.

In FIG. 2 shows one possible block diagram of a device for controlling the operation of a street lamp.

In FIG. 3 a), b), c) a segment of a street or track is shown to explain the method of lighting it using a two-way radio communication channel between cars moving along it and control units for the operation of street lighting fixtures.

The best embodiment of the invention.

The main idea of the invention is to equip light sources (lamps) that are used to illuminate streets, freeways and other objects with a new functional device, which, in addition to the main function of the object itself, performs the following functions:

- automatically registers in the dark, passing near a light source vehicles or passing pedestrians;

- automatically changes the operating mode of the street light source by increasing its brightness when the vehicle or pedestrian is closer to a certain distance with respect to the light source.

To register the presence of vehicles or pedestrians in the vicinity of the street lighting fixture, a special, coded radio signal is received. The transmitter of this signal is located on the vehicle or it is located near the pedestrian, and its power determines the range from which the radio signal can be received by the radio receiver, which is part of the device for regulating the operation mode of the lamp.

After receiving and decrypting the radio signal, the device automatically turns on the lighting until this signal stops. For example, until the car, pedestrian or cyclist drives off or departs from this street lamp - until the next. And so on.

Let us consider in more detail the main steps of the method and the operation of embodiments of the invention using FIG. 1-3.

In FIG. 1 a), b), c) schematically shows the three phases of the operation of the light sources 22 during the movement of two vehicles (for example, cars 2,3) with the headlights 29 on the road 1 to meet each other in the simplest embodiment of the invention. For clarity, we assume that the middle part of the road 1 can be illuminated in zones 21 using light sources 22 (lamps 22) as shown in Fig. 1.

According to the first independent claim, the invention proposes to use a method for controlling the lighting of objects 1 of different infrastructure by creating at the objects 1 of lighting (for example, on the road 1) temporary dynamically changing zones 21 with different levels of illumination.

In FIG. 1 these zones are shown in the form of circles whose radius 23 is the same for all light sources 22. The shaded circle 21 corresponds to the high brightness of the lamp 22. The non-shaded part corresponds to the low brightness of the source 22 or when it is turned off.

The lighting zones of cars 2,3 created by the high beam headlamps 29 included (with a range indicated by R2,3 in Figs. 1, 3) or the low beam headlamps 29 (r2,3) are also shown with the corresponding shading of these zones.

To form dynamically changing zones 21 of the illumination created by the light sources 22, use is made of the operation control unit 4 of at least one light source 22 (lamp).

It can be placed inside the lamp luminaire 22 or located next to the lamp 22, for example, on a lighting pole of road 1 in a separate housing. Using one unit 4, it is possible to control the operation of one light source 22 or several light sources 22 located in one lampshade, spotlight or adjacent lighting masts.

One possible embodiment of the block diagram of block 4 is shown in FIG. 2. It contains a radio receiving antenna 5 connected to the input of the radio receiving device 6, which are designed to receive coded radio signals 7 (at a specific frequency and with a specific code), their amplification, processing and decryption using a decoder 8.

The control unit 4 also contains a driver 9 of the control signal 10, with which the light level in the corresponding zone 21 is changed. It is configured to receive the encoded radio signal 7 in the dark. In this case, the radio signals 7 are automatically generated using the radio transmitter 24, which is located on the object or subject in the form of a corresponding electronic device. A subject or object with such devices can move in space with respect to blocks 4 and corresponding lamps 22. The transmitters 24 can be placed, for example, on cars 2 and 3 or on pedestrians 2,3.

Block 4 can be turned on at night in various ways in manual mode or automatically by applying a supply voltage or control signals to turn them on to the specified nodes of block 4.

In the simplest version, switching on in the dark is carried out from the control room by supplying a supply voltage of 220 V to line 14 and other nodes of unit 4.

In order to automatically turn on the units 4 in the dark, you can use the light relay 11 (for example, FR-602).

At dusk, the level of the natural light signal 12 becomes lower than the threshold value and with the help of a photorelayer 11, through the closed contacts 13, a 220 V supply voltage is supplied from line 14 to a power supply 15, in which the AC voltage 220 V is converted to a constant voltage, which is necessary for inclusion in the operation and power of the nodes of the radio receiving device (blocks 6, 8, 9), for example, a voltage of the order of 5-12 V.

The circuit shown in FIG. 2 allows you to automatically turn on the unit 4 in the work at night and adjust the brightness of the light source 22 by turning it on and off, if a car 2 or 3 with a radio transmitter 24 approaches it closer to a certain distance R _max .

The distance R _max from which radio signal 7 can be received can be adjusted by changing the sensitivity of the radio receiver 6. It can be, for example, of the order of R _max = 20-200 m.

When receiving the radio signals 7 and their decoding, a voltage is generated at the output of the decoder 8, which is fed to the coil 16 of the relay of the shaper 9 of the control signal 10 and, through the closed contacts 17, a voltage of 220 V is supplied from the line 14 to the lamp 22. Lighting is performed using the lamp 22 section of road 1 in the hatched zone 21, when it passes a car 2,3.

The proposed technical solution has a significant difference from the method of interaction of cars 2,3 and additional radio transmitting devices standing along the roads, described in detail in the patent of the Russian Federation No. 2364528.

In the analogue described in the said patent at dusk, devices located along the streets can transmit radio signals around them and force the headlight mode of 29 cars 2,3 to be switched to optimal mode (for example, turn on or off headlights 29 of one type or another) or transmit for cars 2,3, additional telemetric information about traffic signs, traffic lights, etc. (p. 9-10 of the description). And due to these actions, to solve the problem of the invention is to reduce the likelihood of blinding on vehicles and to increase safety when using the photo-dazzling system described in this invention.

And in the technical solution according to this invention, radio signals 7 are transmitted from vehicles 2,3 to luminaire control units 4, which automatically increase the brightness of the luminaires 22 when cars 2,3 are traveling near them, and thereby solve another problem of the invention - save electrical energy, which is spent at night to ensure the operation of light sources 22.

If instead of the power fixtures 22 and other units of block 4 of line 4 of line 14 of 220 V, an autonomous power source 18 is used using solar panels 19 (or wind generators) and battery 20, then additional energy savings are possible due to the use of accumulated in battery 20 in the daytime 30 sun energy.

Through the use of an autonomous power source 18, it is also possible to reduce the material consumption of the lighting system by eliminating the wires of the supply line and reduce the cost of building lighting systems. Such street lighting systems are most beneficial to use at objects with low traffic in the evening. For example, on roads in rural areas, to illuminate the roads of country cooperatives, small towns, sidewalks and bicycle paths in parks, recreation areas.

As the lamps of the light source 22, LEDs can be used.

At night, to start unit 4 in operation, you can use the signals generated from the control room controlling the lighting operation of the corresponding object 1 in manual or automatic mode, for example, as in the analogue described in the automated control system for outdoor lighting (ACS NO) OM -SHINE".

The mode of street lighting at night, in standby mode, 4 cars 2,3 approaching the control device may be in the form of various states of luminaires 22: off state of luminaire 22; its work with reduced brightness and lower power consumption, for example by 30 or 50%.

The circuit shown in FIG. 2 can be used to control the operation mode of the lamp 22, consisting of two lamps. Adding another relay to block 19, you can switch the lamps from the mode of their parallel connection to the mode of their sequential inclusion so that in the standby, energy-saving mode, the lamp will consume 4 times less power.

According to the invention, the encoded radio signal 7 is generated automatically using a radio transmitter 24 located on the subject or object 2,3 during the entire time the subject or object moves at night near such a lighting system.

The ways to turn on the transmitters 7 in the evening may be different. In the simplest version, a manual switch can be provided for this, or this switch can be synchronized with the electronic clock of the device. It can be made in the form of a photo relay, which is installed on a car 2,3.

The start-up of the transmitter 24 can also be carried out using other nodes and systems of the car 2,3, as well as using its on-board computer.

For vehicles 2,3, the transmitters 24 can be implemented as part of various nodes of manned and unmanned vehicles with similar functions. They can be placed, for example, in the security systems of automobiles 2,3, in blind prevention systems, in key fobs, pagers, radars, and so on.

In the simplest embodiment, the radio signals 7 can be coded radio signals that are periodically sent to the air during the movement of vehicles 2,3 or pedestrians. The duration of such radio signals can be selected, for example, in the range from 0.001 to 0.5 seconds. The signal repetition period may be, for example, from 0.002 to 1 second.

Due to the fact that the subject or object 2,3 can approach and move away with respect to the lighting zone 21 illuminated by the lamp 22, the level of the radio signal 7 at the input of the radio receiver 6 of the block 4 automatically changes. In this case, a simple and reliable way to control the operation of the lamp 22 in depending on the speed of movement of the subject or object 2,3 near the light sources 22 and solve the problem of the invention with the above technical result. As devices for organizing such a control system, you can also use miniature microprocessor-controlled transceivers, which are widely used in smart home systems. The operating range of such transceivers is usually about 20-300 m, which is enough to organize the operation of such a system at most facilities 1.

For pedestrians, you can use electronic devices wearable by them, made in the form of miniature keychains for keys or cell phones containing micro-transmitters for the automatic generation of coded radio signals 7.

There are also options for implementing a method of controlling the operation of street lighting with two-way radio communication between block 4 and objects or subjects 2,3.

When these options are implemented, the control unit 4, in addition to the radio receiver 6, also contains its own radio transmitter 25 with a transmitting antenna 26, with the help of which an encoded radio signal 27 can be generated near the control unit 4. It can be received, for example, in a car passing nearby 2.3 s using the radio 28.

In FIG. 2 these nodes and signals are shown by a dotted line. Radio signals 7 and 27 may differ in both frequency and code, but may be completely identical.

Using these nodes and signals, you can make two-way radio communication between cars 2,3 and the control unit 4 and further expand the capabilities of the proposed method in terms of increasing, for example, road safety at night on the streets 1.

As devices containing transceivers 24, 28 on vehicles 2,3, you can use, as already mentioned, modified car alarm systems, their panels (pagers), as well as anti-dazzle systems using a radio channel to identify vehicles in the area of possible dazzle by headlights 29 high beam, the work of which is described in the patents of the Russian Federation 2578828 and 2364528.

In FIG. 3a), b), c) schematically shows three phases during the movement of two vehicles (for example, cars 2,3) with automatically switched headlights 29 high and low beam as cars 2,3 move along road 1 relative to control units 4 and fixtures 22.

Unlike the previously described version of the operation of the control unit 4, the use of additional radios 28 and radio transmitters 25 allows not only to automatically turn on the light sources 22 when cars 2,3 are passing near them, but also to control the light state of the headlights 29 of these cars or remotely activate the work their transmitters 24, when they enter the zone of interaction with the blocks 4 by means of radio signals 7 and 27.

For example, when a car 2 and 3 approaches a block 4 closer than a certain distance from which radio signals 7 can be received, the corresponding lamp 22 is turned on, a good illumination zone 21 is formed, and at the same time, radio signals 27 are detected on cars 2,3, which are generated automatically by transmitters 25 in block 4. In FIG. 2 these relationships are not shown.

The process of generating these signals 27 may be similar, for example, to the process of automatically generating signals in a glare avoidance system described in RF patent No. 2578828. The process of controlling the state of the light sources 22 is similar to the process when switching the headlights 29 from the main beam to the dipped beam when cars 2,3 approach each other, the only difference being that the brightness of the headlights 29 of the cars 2,3 does not decrease when they approach each other, but rather , increases the brightness of the lamp 22 when driving vehicles 2,3.

As already mentioned, the coded radio signals 27, 7 can be completely identical. In this situation, the blinding prevention system described in RF patent 2578828 can be used for two purposes: as a system that allows you to automatically switch the headlights of 29 cars 2,3 when they come closer to each other closer than a certain distance and as a system for automatically controlling the operation of lamps 22. For such a system, blocks 24 and 25, as well as blocks 6, 28, may be identical.

The basic principle of operation of such transceiver systems is that at the time when a single coded radio signal 7 is being transmitted, the receiver is blocked — they are gated so that signal 7 can be received only from other cars.

This technical solution can significantly simplify and unify the design of the devices to prevent blinding on cars 2,3 and blocks 4.

When using the same type of signals 7 and 27 in anti-glare systems between cars 2,3 and in street lighting control systems 1, their operating range is chosen so as to exclude self-excitation of street lighting system 1.

For example, if radios 6 with transmitters 25 are installed on each adjacent column or mast, then the power of the radio transmitters 25 and the sensitivity of the radios 6 are chosen so that the radios 6 do not receive radio signals 7 (27) from neighboring units 4. For this, less powerful radio transmitters can be used 25 and less sensitive radios 6 than radios 28 and radio transmitters 24 installed on vehicles 2, 3.

For example, the range R _{max of the} interaction between the receivers 28 and the transmitters 24 installed on the cars 2,3 for the systems to prevent blinding from the headlights of 29 cars 2,3 can be adjusted to a range of about 300 meters, and for systems of automatically switching on the light sources 22 the range of possible interaction of neighboring blocks 4 for controlling the operation of the luminaires 22 can be set significantly less, for example, of the order of 10-30 m. Due to the fact that the sensitivity of the radio receiver and the power of the radio transmitter In vehicles 2.3, the sensitivity is higher than the sensitivity of the radio receiver 6 and the transmitter power 25 of blocks 4, the on and off range of the next lamp 22 by radio signals from cars 2,3 can be, for example, about 100 m. In this case, neighboring blocks 4 will not interact together.

A combined version of the construction of a control system for the operation of the luminaires 22 is also possible, when units 4 are installed on one lighting column, including both a receiver 6 and a transmitter 25 capable of receiving and transmitting the same type of radio signals 7, and on an adjacent lighting column (or on several adjacent poles lighting) install blocks 4, which contain only radios 6. Due to this, it is possible to separate blocks 4 with radio transmitters 25 from each other in a considerable distance (a multiple of their installation step i) and increase the reliability and comfort of the lighting system.

With this option, those units 4, in which there are transmitters 25, can perform an additional function - the function of a radio signal repeater 7 (27) from vehicles 2,3 approaching them to the next lighting column (s) where there is no radio transmitter 25. And due to this to ensure the early inclusion of several light sources 22 around moving vehicles 2,3 and the large size of the lighting zone 21.

A possible implementation of the method and devices when the radio signals 7 and 27 are formed at the same frequency, but with different codes. One code is used for the glare avoidance system, and another code is used for the lighting control system. In this case, it is possible to completely exclude the self-excitation of the street lighting control system due to the closely spaced light sources 22 with blocks 4.

Switching the headlight mode of the headlights 29 from high to low beam, in the illuminated areas 21 of road 1, reduces the likelihood of dazzling oncoming vehicles, malfunctions in the video monitoring system of automatically manned vehicles and an additional positive effect appears - there is a fuel saving of cars 2,3, which was would be spent on ensuring the operation of more powerful headlights 29 high beams. By reducing the operating time of the headlamps 29 high beam also increases their service life.

If cars 2,3 drive along unlit highway 1, where there is no street lighting system described above, then when cars 2,3 approach each other closer than a certain distance (for example, closer than 300 m), a single coded signal 7 identifying the car is received using radio 28 2 or 3 driving with the main beam on and the headlights 29 automatically switch from high to low beam on both vehicles by exchanging radio signals 7.

In the system described in RF patent No. 2578828, the radio signals 7 are automatically generated by the glare avoidance system when it is turned on.

If the inclusion of the anti-glare system is synchronized with the time the ignition of the vehicle is turned on, then vehicles 2,3 will interact with each other and with the source control units 4 when they are turned on.

This option is not entirely convenient, because all the time radio signals 7 will be sent to the air and almost constantly, radio interference will be created at the selected frequency, which can impede the operation of other nodes and systems of this or neighboring vehicles 2,3.

The algorithm of the anti-glare system can be considered more rational when the inclusion of the transmitter 24 in the mode of repeated sending of signals 7 is synchronized with the time when the high beam headlights 29 are turned on, and when the low beam headlights 29 are turned on, only the air is listened to, followed by the automatic generation of signal 7 if a signal 7 is received from another car 2,3, on which the main beam headlights 29 are turned on. To start the operation of the described algorithm for the operation of block 4 using the system To prevent blinding and a single radio signal 7, you must either turn on the main beam in those areas where the described method of switching on the light sources 22 is used, or use an additional transmitter 25 in block 4, which will cyclically generate the radio signal 27 identical to signal 7 (with the same code and same frequency) and activate the operation of the transmitter 24 on the car 2,3. In this case, the gated radio 6 will receive only signals 7 (27) from the transmitters 24 of passing cars 2,3, and the signals from the transmitter 25 of block 4 will not be received.

Using this signal 7, formed in block 4, it will be possible to activate the operation of the transmitter 24 on the vehicle 2,3 according to the same algorithm that is described in detail in the patent of the Russian Federation No. 2578828, and turn on the light sources 22 to illuminate street 1 during the movement of the car 2,3 as described above.

After cars 2,3 are separated by a distance greater than the threshold from each other, or from the next block 4, they will automatically turn on the driver's selected headlight mode 29. For example, the main beam headlights 29 will turn on (or the dipped beam will remain on) . And so on, until the next oncoming (or passing moving) car 2, 3 (or lamp 22 with a control unit 4).

Due to the introduction of the above communication channels 7, 27, the turn-on time of the next light source 22 will correspond to the travel time of each vehicle 2,3 under it or the movement of other road users at virtually any speed and the energy that is spent on lighting will be saved Roads 1, when subjects or objects 2,3 do not move along them.

If a car 2,3, for example, stopped at night on the side of the road, then its stop will be illuminated by the nearest light source 22, which makes it noticeable from a long distance and further increases the safety of all participants in the movement.

In order to exclude the effect of blinking of the light source 22 at the maximum range, it is advisable to make a certain delay for switching off the light relay 10 (for example, about 1-3 seconds).

As cars 2,3 drive under the lights 22, they automatically turn on in high brightness mode, forming, as it were, synchronously running with the speed of cars 2,3 lighting of road 1 near cars 2, 3. Due to this, it is possible to provide a comfortable mode for each motorist Driving with as good street lighting as possible without blinding effects.

The proposed system can be used in railway transport and in other areas of transport and industry.
