In several parts of the world, large cities manage high vehicular flow crossings by means of traffic cameras with turns or magnetic induction loops, but these control options require a high investment in personnel and spare parts. In the first one, a structure is needed to place the camera and for the second one, it is necessary to periodically change because the loop ends broken due to the flow of vehicles.

Sinowatcher thinking about this problem has developed a sensor model that allows us to keep a record of the vehicle flow in each lane, detect speed, the size of the queue in the lane, and work together with the crossing controller. All these data are obtained wirelessly from the crossing and are transmitted to both the controller and the city control center.

Working principle of traffic vehicle detector

At a certain point on the earth, the intensity of the earth's magnetic field is basically constant for a period of time. When a vehicle passes by, it will form a continuous disturbance to the intensity of the magnetic field. The motion information of the vehicle can be obtained by calculating the disturbance.

Functions of data acquisition center

Communication information, communication status information, vehicle detector detection information and status information are displayed on the screen. It includes the operation status, power supply voltage and communication status of the detector.

Browse the information of vehicle detector. It includes detector type (function), detector position and attribute.

System time modification.

The parameters of the detector are modified, including communication parameters, location information, corresponding relationship between vehicle detector and lane, and operation parameters.

The output mode is various. TTL high effective, TTL low effective, switch normally open, switch normally closed, serial port, 485, 422, network port, etc. The output mode can be customized according to the actual needs.
