Parking Information Acquisition System Based on LoRa and Geomagnetic Sensor

摘要

Aiming at the problems of poor management and inefficiency of the exiting outdoor parking system, a set of parking information acquisition system based on LoRa wireless network and geomagnetic sensor technology is proposed. The design of front-end acquisition equipment and LoRa gateway is introduced in detail. Combined with the preprocessing of the collection data and the dynamic threshold value correction algorithm, the vehicle detection sensor effectively reduces the false and the missed detection rate. The experimental results show that the system has high detection accuracy and reliability.
