The Design Of The Intelligntparkin Lot Management System Basedon Internet Of Thing

With the rapid development of China’s economy and the improvement of people’s living standard continuously, many cities arise "parking" problem. Therefore, efficient, safe and reasonable management, quick and convenient intelligent parking lot management system has become necessary facilities in many large comprehensive buildings and residential area. Intelligent parking lot has becamed a lot research topic in the intelligent building technology. It not only can effectively solve the disorderly parking place caused traffic chaos, but also can promote the regularized development of traffic facilities.In this paper, we study the design process of the intelligent parking lot. The parking card of Users use RFID technology, the design of monitoring and control system for parking use Zigbee technology and wireless sensing technology. Parking sensor is constituted by CC2430and IR1838; intelligent parking lot collects and monitors data remotely using RS485connection scheme. We use AT89C52single chip microcomputer as the controller to realize the Ethernet/RS485conversion interface design. The hardware circuit mainly includes two parts: one part is AT89C52and Ethernet interface circuit, the other part is AT89C52and RS485Network interface circuit. The software design of AT89C52is the key of interface of RS485Network and Ethernet, In the design, software adopts C/S mode, we use AT89C52and computer network as server and client.
