NB IOT parking space detector is mainly used to detect the parking space status on the parking space, judge whether there are vehicles parked, and link with the background management system. It uses NB IOT wireless signal data to realize data exchange with the background management system, and can calculate the parking time of vehicles on the parking space.

Through the analysis of the data collected by the geomagnetic equipment, the parking lot management system can realize the parking lot GIS management, parking space monitoring, and the backstage management of operators and geomagnetic equipment.
