COMA roadside parking system uses the principle of geomagnetic detection to detect motor vehicles. Wireless geomagnetism detects motor vehicles by analyzing the changes of the earth's magnetic field. In the case of no motor vehicles on the geomagnetism, the earth's magnetic field is in a relatively stable state, and the system defaults to no vehicles; when a motor vehicle passes over the geomagnetism, the earth's magnetic field is disturbed. Change, then the system will think that there is a car.
The wireless geomagnetic detection is buried on the surface and powered by its own battery. The vehicle information detected by the detector (traffic parameters such as presence, flow, speed, vehicle length, and occupancy rate) is sent wirelessly to the geomagnetic gateway installed on the roadside. The geomagnetic gateway transmits vehicle information to the cloud and other application systems through wireless signals.
The wireless geomagnetic detection is buried under the surface of the parking space. Whenever a vehicle is parked, the arrival of the vehicle is detected according to the change of the magnetic field around the geomagnetic detection. When the vehicle stops the signal is stable, the ggeomagnetic detection sends the signal to the geomagnetic gateway installed at the appropriate location. Similarly, when the vehicle leaves, the wireless geomagnetic detection detects the vehicle departure information according to the change of the magnetic field, and informs the geomagnetic gateway.
System functions
1. Real-time detection of parking spaces
The geomagnetic sensor detection method is used to obtain the basic parking space status data; the wireless geomagnetic vehicle detector, receiver and receiver base station are used to form a data acquisition network, thus ensuring the real-time nature of the obtained parking space status.
2. Data traceability function, data statistics function
The data uploaded to the platform by the receiving gateway is processed and stored permanently, providing big data channel support for traffic supervision units and parking lot management departments to analyze traffic data and orderly and standardized management of parking lots.
3. Charge supervision function
The parking space management system based on wireless geomagnetism, by comprehensively processing the data obtained by geomagnetism, can be accurate to each parking space, the number of parked vehicles per day, the length of each time, make accurate statistics, and get the corresponding algorithm through the algorithm. Fees payable. It effectively eliminates management loopholes and ensures the benefits of the parking lot.
