Abstract:In order to solve the problem of reverse car search in intelligent parking lot, a reverse car search method based on PC client and mobile client application intelligent parking lot or garage is presented. The ultrasonic detection method is used to detect whether the parking space is available, and the monitoring equipment and parking space are set up to complete the parking space image acquisition in one-to-many way. The STM32 single chip microcomputer system is used to transmit the monitored license plate number and parking space number to the server through ZigBee wireless communication network. ArcGIS is used for the design and production of the site map, and the improved A ? vehicle search path planning algorithm proposed in this paper is used to eliminate the constraints of the search element range and redundant points, realize the path planning, and complete the vehicle search guidance. Comparing the simulation results of path optimization in different environments, the improved A ? algorithm reduces the number of search nodes by 60% ~ 80% compared with the breadth first algorithm.
