The disadvantages of this system are the same as those of the above technical solutions.

The objective of the invention is to increase efficiency in terms of reliability of the results, expanding the list of controlled road signs and paragraphs of traffic rules, mobility and ease of operation of the system.

For this purpose, a system for monitoring compliance with traffic rules, in particular, the vehicle’s high-speed mode, the rules for driving through railway crossings, regulated intersections and pedestrian crossings, and the requirements of road signs, is proposed, which contains a signaling device located at the place of control and an actuating device placed on the vehicle exchanged between information on a radio line organized using spread spectrum technology with pseudo-random frequency hopping and time division of channels fishing.

The signal device includes a first controller connected to a transmitting device, which contains a series-connected frequency synthesizer, a transmitter, a power amplifier, an antenna filter and an interface for connecting an external antenna, as well as with a discrete signal input unit.

The actuator includes a second controller connected to the transceiver with a built-in antenna, an external memory unit, a liquid crystal monitor, as well as an analog and discrete signal input unit and with a relay output unit.

Signal devices are capable of transmitting information about a controlled parameter using controllers' service signals, in a certain sequence, with spatial diversity of signals, and also with the ability to connect to traffic control devices through discrete signal input blocks for collaboration.

Actuators are configured to receive information about the controlled parameter from signaling devices in a specific sequence, to fix the committed violations of the monitored parameters in the external memory unit, audio and video information of the vehicle driver about the committed violations, introduced and canceled restrictions, established road signs through terminal devices connected via controller interfaces, as well as control of signal devices of the vehicle through the block of relay outputs.

The executive device analyzes the information received from the signal devices and from the vehicle speed sensor received through the input unit of analog and discrete signals, detects violations of the controlled parameters in time and physical quantity and stores the information in the external memory unit.

Further, information about the monitored parameter exchanged between the signal and actuator will be referred to as the “parameter code”.

The drawing shows a structural electrical diagram of a traffic control system.

The traffic control system contains a signal device 1 located at the control place and an actuator 11 located on the vehicle 10, while the signal device 1 comprises a first controller 3 connected to a transmitting device 4, including a transmitter 5, a frequency synthesizer 6, a power amplifier 7, an antenna filter 8 and an interface for connecting an external antenna 9, as well as with a discrete signal input unit 2, the actuator comprises a second controller 15 connected to an external memory unit 16 and a transceiver with Structures antenna 17, as well as the input unit of analogue and digital signals 12, relay output unit 13 and the liquid crystal monitor 14.

Known circuits are used in the signal device 1 and actuator 11. The controllers 3 and 15 used in the signal and actuating devices are identical in composition and capabilities.

A radio link for the exchange of information between the signal device 1 and the actuator 11 is organized using the well-known technology of spreading the spectrum with pseudo-random frequency hopping and time division of channels.

The operating frequency band is divided into a certain number of channels. For call, request, answer and call procedures, “N” frequency channels are used.

Each channel is divided into time intervals of a certain duration, with each time interval corresponding to a specific channel. The time intervals are numbered according to the clock of the alarm device. The transmitter in each time interval uses only one channel.

The signal device 1 transmits in even time intervals, starting from zero. Actuators 11 must always “listen” at even time intervals, since they never know when they can be accessed.

The transmitter of the signaling device performs K frequency tunings per unit time. The frequency tuning order is determined by a sequence having a very large period length. The choice of sequence is carried out according to the own clock and the electronic address of the controller of the signaling device.

The receiver of the actuator in standby mode performs tuning according to “N” frequencies, remaining at each for the time necessary for tuning the signal device to “N / 2” frequencies. For example, when using 10 frequencies, the receiver is on one frequency for 5 time intervals, then tunes to another frequency, while if the receiver was on the frequency of the first half of the range, then it will be tuned to the frequency of the second half of the range. When a request is received from a signaling device, the actuating device carries out temporary synchronization, and then its receiver is reconstructed synchronously with the transmitter during the entire time that it is in the zone of operation of the signaling device.

The general format of packets used in a radio channel consists of three parts: an access code, a header, and useful information.

Asynchronous packets are used, without establishing a connection.

Access codes are service signals of communication controllers and are used for notification and exchange of service information.

Three access codes are used.

 The request access code is used to detect actuator modules within the range of the signal device.

 The parameter code contains a sign of the controlled parameter.

 The restriction removal code contains the corresponding attribute.

The traffic control system operates as follows:

The TS executive device is constantly in the standby mode of the request, tuning in frequencies according to the established algorithm.

At the monitoring site, alarm devices are installed. The antenna diagram of one signaling device is directed towards the movement of vehicles, and the antenna diagram of another signaling device is directed along the movement of vehicles of the same direction.

Signaling devices transmit the “request access code” and “parameter code”, while information through the “request access code” and “parameter code” is transmitted through an antenna directed towards the movement of vehicles, and only “parameter code” information is transmitted through the other antenna .

The TS executive device analyzes the received information from signaling devices of a given direction and, if the received “parameter code” coincides with the “parameter code” in the memory of the executive device, a violation of the monitored parameter is recorded.

Use cases

1. Speed control

Signaling devices are installed at the level of the speed limit sign (designated start of the settlement) and at the place where the action of the speed limit sign ends (at the exit of the settlement).

The signal devices installed at the speed limit sign transmit the “request access code” and “parameter code”, the signal devices installed at the end of the speed limit action transmit the “request access code” and “restriction removal code”.

When approaching the speed limit sign, the vehicle enters the coverage area of the first signaling device. The signal device in even slots cycles through the “request access code” and “parameter code”. The TS executive device in the first even slot receives the “request access code”, performs the time synchronization procedure, and enters the call waiting state. In the next even slot, the actuator receives a “parameter code”.

Continuing movement, the actuator moves into the coverage area of another signaling device and receives a “parameter code”. The executive device analyzes the received information, compares it with the code stored in the controller’s internal memory and, if the codes match, activates the vehicle speed control program, notifying the driver of the restriction introduced by voice message, as well as graphic information on the monitor.

If the permissible speed is exceeded, the vehicle driver receives a warning signal, then, if the driver has not reduced the speed to the allowed value, after a set time the executive device records the time and nature of the violation, puts the vehicle’s signaling devices in a special mode.

Monitoring of the speed mode continues throughout the vehicle’s movement in the controlled area (in the locality), and it is possible to record each speeding as a separate violation.

At the end of the monitored section (at the exit from the settlement), the executive device receives a “restriction removal code” and turns off the speed control program. The driver receives a voice message about the abolition of the restriction with the display of information on the monitor.

2. Control of passage of regulated intersections of roads, pedestrian crossings and level crossings

Signal devices are installed together with traffic lights (semaphores) and are connected to them through input blocks of discrete signals.

When the traffic light switches from “enable” to “warning” signal, the first signaling device starts transmitting “request access code” and “parameter code” according to the algorithm considered earlier.

When the traffic light switches from a “warning” to a “prohibitory” signal, the second signaling device starts transmitting a “parameter code”.

When the vehicle’s actuator receives a “warning” traffic signal, it receives a “request access code”, performs a time synchronization procedure, switches to call waiting mode and receives a “parameter code”.

When the vehicle moves to a “prohibitory” traffic signal, the executive device receives a “parameter code” in the coverage area of another signal device, analyzes the received information, compares it with the code stored in the controller’s internal memory, and when the codes match, it records the time and nature of the violation, puts the vehicle’s lighting fixtures in a special mode, notifies the driver of the violation by voice message with information displayed on the monitor.

When the traffic light switches from the “warning” signal to the “enabling” signaling devices, they stop working.

For railway crossings, the difference between the algorithm is that the signal devices begin to work on transmission when the "inhibitory" semaphore signal is turned on.

3. Monitoring compliance with the requirements of marks

A feature of the algorithm is that the signaling devices constantly transmit a “request access code” and a “parameter code”. The first signaling device constantly transmits a “request access code” and “parameter code” with a set cycle; other signaling devices constantly transmit only a “parameter code” as previously discussed.

For signs prohibiting stopping and parking, the difference is that after receiving the “request access code” and “parameter code”, the actuator activates the vehicle speed control program and, when the speed drops to zero, after a set interval of time, it records a violation. At the end of the restriction section, a signal device is installed that transmits a “restriction removal code”.

4. The technical means of the system make it possible to alert drivers of vehicles of all signs installed on the road, both permanent and temporary, as well as dangerous conditions on road sections (heavy fog, ice, snow drifts, etc.).

3. Speed limits in settlements, in residential areas, in domestic territories, on sections of highways and roads.

4. The maximum speed determined by the technical characteristics of vehicles.

- "Maximum speed limit"
