Problems solved by technology

Among the above three methods, the first two are wired detection methods, which require large-scale changes to the existing parking lot and then construction and wiring. The cost is relatively high, especially the video-based parking space detection method
The method based on the Zig Bee network is a wireless method, which is more flexible and convenient to install than the wired method, but Zig Bee work

Abstract

The invention relates to the technical field of intelligent transportation, and discloses a wireless anti-interference parking spot detection system based on geomagnetic sensing. The system comprises wireless geomagnetic sensor terminal nodes responsible for parking spot detecting, 433MHz wireless routing nodes responsible for data forwarding, and a network center responsible for monitoring data gathering. Each wireless geomagnetic sensor terminal node is arranged below a parking spot, detects the current state of the parking spot based on geomagnetic information, and realizes multiple access based on a conflict avoiding protocol. The routing nodes are responsible for collecting data of the wireless geomagnetic sensor nodes and forwarding the data to the network center by means of multi-hop routing. The network center gathers all the parking spot detection data and displays the data to parking users. The system is characterized in that the whole system adopts a 433MHz ad-hoc wireless network.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, more specifically, to a wireless anti-interference parking space detection system of geomagnetic sensing. Background technique [0002] With the development of the economy, people's living standards are getting higher and higher, cars are gradually entering the homes of ordinary people, and the number of cars in various large, medium and small cities has become an explosive growth trend. The means of transportation facilitate people's life, but the increasing number of vehicles also brings a lot of inconvenience to life to some extent. The commercial buildings in the central part of the city and the few parking places near the commercial center are far from meeting the actual needs. Many public places are limited by the bottleneck of parking difficulties, and it is difficult to improve the current situation in the short term. "Parking difficulty" is a major problem that needs...
