手机与ZigBee结合的城市停车系统

Urban parking system based on mobiphones and ZigBee networks

为解决现有城市智能停车系统普遍存在的建设及运营成本高、缺乏与停车用户交互等问题,提出一种用户智能手机与停车场ZigBee网络相结合的架构。介绍该架构的组成、硬件方框图、软件流程图和设计的停车场、停车位寻优算法,给出系统的实物展示及测试结果。测试结果表明,将选用的传感器用于车位检测准确可靠,设计的停车场、停车位寻优算法的运行结果符合人们的生活习惯,开发的ZigBee网络与智能手机软件之间能够良好地通信,该架构的可行性得到验证。

The architecture of urban intelligent parking systems which combining users＇ mobiphones and ZigBee networks at parking lots was proposed to overcome the disadvantages existing in current urban intelligent parking systems. These disadvanta- ges include high construction and maintenance cost, shortage of user interactions, and etc. The components, the hardware block diagram, the software flow chart, and the designed optimization algorithm for determining parking lots or parking spaces were presented in detail, Test results of the developed system were provided at last. The test results indicate that the selected sensor provides accurate and reliable detection results of parking spaces, and the results provided using the designed optimization algo- rithm for choosing parking lots or parking spaces are in accordance with peoples＇ habits, and the developed ZigBee network and the mobiphone software interacts well with each other, the feasibility of the proposed architecture is simultaneously verified.
