Roadside Parking System Based on Wireless Geomagnetic Technology to Solve the Problem of Roadside Pa

1 Tigerwong roadside parking working principle tigerwong 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. When there are no motor vehicles on the local magnetic field, the earth's magnetic field is in a relatively stable state, and the system defaults to no vehicle; When the motor vehicle passes over the geomagnetic field, it will cause the change of the earth's magnetic field. At this time, the system will consider that there is a vehicle. Wireless geomagnetism is embedded on the ground and powered by its own battery.

The vehicle information detected by the detector (presence, flow, speed, vehicle length, occupancy and other traffic parameters) is sent wirelessly to the geomagnetic gateway installed on the roadside, and the geomagnetic gateway transmits the vehicle information to the cloud and other application systems through wireless signals. The wireless geomagnetism is buried under the surface of the parking space. Whenever a vehicle stops, the arrival of the vehicle is detected according to the change of the magnetic field around the geomagnetism. When the vehicle stop signal is stable, the geomagnetism sends this signal to the geomagnetic gateway installed at the appropriate position. Similarly, when the vehicle leaves, the wireless geomagnetism detects the vehicle leaving information according to the change of magnetic field and informs the geomagnetic gateway.

II. System architecture the system is mainly composed of vehicle acquisition equipment, data upload equipment, management platform and payment. III. system function 1. The parking space real-time detection function adopts the geomagnetic sensor detection method to obtain the basic parking space status data; The data acquisition network is composed of wireless geomagnetic vehicle detector, receiver and receiver base station. The frequency of samples collected by the vehicle detector is milliseconds, so the real-time performance of the obtained parking space state is ensured. 2. Parking space guidance function is based on the parking space guidance and management system of the Internet of things. Based on the communication between wireless sensor network and Ethernet, the parking space usage is detected by geomagnetism, and the information is transmitted to LED screen, mobile phone or terminal user computer through network equipment and 3G equipment, According to the guidance of the above released information, parking people can quickly find free parking spaces for parking. Managers can timely count the traffic flow in different periods, optimize the allocation of parking space resources, and improve the intelligent level of the parking lot. 3. The data traceability function and data statistics function receive the data uploaded by the gateway to the tigerwong platform and store it permanently after processing, so as to provide 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.

When an emergency occurs, the purpose of event tracing can be achieved by calling data. 4. The charging supervision function is based on the parking space management system of wireless geomagnetism. Through the comprehensive processing of the data obtained by geomagnetism, it can be accurate to each parking space, the number of vehicles parked every day and the duration of each time, make accurate statistics, and obtain the corresponding receivable expenses through algorithm. Effectively eliminate management loopholes and ensure the revenue of parking lot or national finance. IV. system features 1. High precision: the earth's magnetic field is basically constant within a few kilometers, but large ferromagnetic objects will cause huge disturbance to the earth's magnetic field. The geomagnetic sensor can distinguish the change of the earth's magnetic field by 1 / 6000, and the impact on the geomagnetism when the vehicle passes will reach a fraction of the geomagnetic intensity, Therefore, the use of geomagnetic sensors to detect vehicles has very high sensitivity. 2. Convenient installation and maintenance, no excavation and construction, and little damage to the pavement.

If the detector is damaged, it only needs to be replaced as a whole without checking the circuit. 3. The geomagnetic sensor uses the change of the earth's magnetic field when ferromagnetic objects pass through, so it is not affected by the climate. 4. Two way high-speed data exchange can be realized between the detector and the receiver, and there is no need to worry about the simultaneous data exchange between each detector and the receiver. 5. The investment cost is low, and once the system is applied, it can greatly reduce the management personnel of the parking lot and reduce the operation cost of the parking lot. Tigerwong parking management system has been inherited for many years! If you have any questions about parking lot system, etc., welcome to consult and exchange.
