Abstract

A parking space detecting system based on a magnetoresistive sensor and the ZigBee is characterized by comprising a ZigBee wireless sensor network unit and an upper computer unit, and the ZigBee wireless sensor network unit is composed of a router, a coordinator and a parking space detector serving as a terminal node. The working method of the system comprises the steps of arousing a node and starting detection, establishing a ZigBee wireless sensor network, detecting the information of a parking space, detecting the state of the parking space and displaying the occupied information of the parking space. The system has the advantages that construction is convenient, cost is low, parking space information is accurate and complete, detecting effect is good, and expandability is high.

Description

(1) Technical field: [0001] The invention relates to the technical field of parking space detection and the field of wireless sensor networks, in particular to a parking space detection system based on a magnetoresistive sensor and ZigBee. (two) background technology: [0002] With the rapid development of society, cars have gradually become a means of travel for residents. Especially in recent years, the number of urban cars has increased sharply, and the ensuing difficulty in parking has become increasingly prominent. Parking spaces have gradually become scarce resources. Smart Parking lot management came into being in order to achieve the optimal allocation of parking space resources, among which the parking space detection device is particularly important. The parking space detection system using magnetoresistive sensors and ZigBee technology has a broad application prospect in parking lot management. [0003] Magnetoresistive sensors have been widely used in the develo...
