Description

A device for controlling automotive traffic control is primarily intended; 1.l study road and traffic and find application in the design of road construction and reconstruction, road maintenance and road transport, and traffic and traffic control.

The known device for counting units of transport, which pass along the road, consists of two photo sensors, raznesepppy along the length of the road and controlling all its styine, connected with them a block of analysis of the traffic situation, made on electrical elements, and counters that he counts. The direction of the vehicle following is determined by the first impulse of the sensor, the line of control of which the transport device doesn’t cut off time before the line and ontrol of the second sensor. This, entering the analysis unit, connects the car's counter of the corresponding direction and at the same time blocks for the preset time the next one of the impulses from both sensors to exclude false counter-processing.

However, there may be two or three cars on the sensor-controlled part of the road. In these cases, the transport that crosses the sensor control lines until it expires. During the time of a given interlock, turned on by the car that entered the control line earlier, is not counted.

At the same time, the error in accounting for the number of cars increases with an increase in the intensity of traffic on the road and at an intensity of 400–800 vehicles per hour, each of the oncoming traffic flows can reach 15–20% of the total number of passing vehicles.

The drawing shows a controlled section of the road and a block diagram of the proposed device.

It contains two sensors 1 and 2, controlling vehicle wing widths 3 with vehicles moving 4-6, block 7 road analysis 7, blocks for registering the total number of cars 8 and reverse 9 directions, blocks for registering the number of overtaking in forward 10 and reverse // directions, first time relay 12, counters that record the speeds of cars following in forward 13 and reverse 14 directions, second time relay 15, a matching circuit 16 that determines the length and category of cars, counters / 7 and 18 categories of cars of the following, for example, in the forward and reverse directions, units for measuring the forward intervals 19 and reverse 20 directions, the recording units for the time intervals

following cars in forward 21 and in reverse 22 directions.

The electrical circuit of the road analysis unit 7 is assembled from two identical sets of relays, one of which is connected to the sensor / and the other to sensor 2.

When receiving a signal from sensors 1 to 2 on the movement of cars, unit 7 analyzes them. At the same time, it transmits the time impulses of a car moving from one sensor to another, to the first time relay 12, the time impulses for the car to pass through the second sensor as it moves along, measured by the second time relay 15 to start the count; kb 13 or 14, for units for registering the total number of ZILIA cars for units for recording time intervals for vehicles (units 21 or 22, depending on the configuration of the track); a start pulse of the coincidence circuit 16 for measuring the length and category of the car; the impulse to start the counters of the registration category of the car / or 18 at the headquarters; and the capability of following the direction, impulse return of the blocks 12, 15 and 16 to the initial state; start pulse of the overtaking registration blocks (block 10 or // depending on the direction of the overtaking).

Blocks 8 and 9 of the registration of the total number of cars and the blocks DC and V / are controlled by the analysis unit 7 directly. The counter 1 and M of the speed registration of the auto cars are controlled by the analysis unit 7 via the first time relay 12: block 20 through block 7 through block 19, and block 22 through block 20.

The car category counters 17 and 18 are controlled by block 7 through blocks 12, 15 and 16, the coincidence circuit 16 being connected to block 7 and receiving data on measuring the time of movement autolyubil through the first time relay 12, and data on the non-displacement time of the mobile. - through the second time relay / 5, working perall fir relay in: RBMEN 12.

Subject invention

A device for controlling motor vehicle traffic meter parameters, containing two sensors spaced apart along the roadway, under | CL: Ichnyonny IKO inputs to the analysis unit associated with the total number of

cars and overtakings in the forward and reverse directions, and with the units for measuring the intervals connected to the units for recording the time of the intervals for the direct and reverse directions, and counters differing from that

in order to increase the reliability of the device, two time relays and a coincidence circuit are introduced into it; moreover, the input of the first time relay is connected to the output of the analysis unit, and the inputs to the corresponding (m counter and

one input of the assembly circuit, the other input of which is connected via the second time relay to the output of the analysis unit connected to the third input of the coincidence circuit, and the output of the coincidence circuit with the counter.
