Smart parking uses the sharing of data through wireless networks to break the information silos, control parking status monitoring, reservation, guidance, remote management, online payments and other functions.
LoRa based wireless networking has the following advantages: no data costs, no wiring, no road construction applications, large networking capacity, long transmission distance, strong anti-interference ability and low power consumption. The Four-Faith LoRa module is embedded in the geomagnetic sensor, when a vehicle enters or leaves the parking space the sensor detects the Earth’s magnetic field changes to determine the status of the vehicle.
The data transfer process: parking state is transferred to the LoRa gateway by wireless, LoRa gateway transmission to the remote server through the GPRS/3G/4G network management centers to achieve rich management function through the backstage management system. The solution topology is as follows:
