A parking space real-time detection system and detection method

Abstract

The present invention provides a real-time detection system and detection method for parking spaces, comprising: a plurality of parking space detection sensors, wherein the parking space detection sensors are multiple, respectively installed in each parking space and used for detecting parking information on the parking spaces; a water pressure detection device, It is connected with the parking space detection sensor, and is used to detect the water pressure value where the parking space detection sensor is located; a wireless repeater and a wireless gateway, the parking space detection sensor is connected with the wireless gateway through the wireless repeater, and each Each of the wireless repeaters is connected to a plurality of the parking space detection sensors; a background server, the background server is connected to the wireless gateway through a communication network, and the communication network adopts a mesh network topology. The invention can adjust the wireless transmission power according to the road surface water condition, and has the advantages of high communication quality and high data reliability.

Description

technical field [0001] The invention relates to the field of parking detection, in particular to a parking space real-time detection system and detection method. Background technique [0002] Existing parking detection devices often use a single detection method, and parking lots, especially road parking, have a very complex application environment with a lot of interference, resulting in insufficient vehicle detection accuracy. In rainy seasons and areas, there is a lot of water on the road, and the geomagnetic sensor works with a fixed wireless transmission power, which makes the communication signal unstable. Due to the special location of the parking lot, there are already large environmental noise, many transmission obstacles and multipath interference. In a strong case, most of the current vehicle detection wireless networks adopt a single-hop star architecture, and the network communication lacks redundant paths, the communication reliability is low, and the cost is h...
