前期研究提出一种智能手机与ZigBee网络相结合的智能停车系统总体架构,具有低成本、交互性强等优点.为具体实现该架构中使用的ZigBee网络,设计了一套停车场车位数据采集系统. 该系统基于ZigBee技术搭建,由中心结点、路由器结点和终端结点组成.中心结点的微控制器选用低功耗的LPC11C14,GSM模块选用SIM300模块.三类结点的ZigBee通信芯片选用CC2530.综合多方面因素,选用基于地磁检测技术的HMC5883L作为车位传感器.尺寸小、安装方便、对非铁磁性物体无反应、可靠性高是该传感器的优点.在硬件电路的基础上,设计了三类结点的数据收发和控制程序. 经测试,所设计的车位数据采集系统实现了预期功能要求,且具有低成本、低功耗的特点.

In our previous study, an intelligent parking system infrastructure based on intelligent mobiphones and ZigBee networks is proposed. The infrastructure is with low cost and good interaction. A data acquisition system of parking spaces is designed to implement the ZigBee network in the infrastructure. The designed system consists of a central node, router nodes and end device nodes. LPC11C14, which is low power consumption, is selected as the microcontroller in the central node. A commercial mode based on SIM300 is used as GSM module in the central node. CC2530 is chosen as the communication chip for the coordinator, the routers and the end devices. HMC5883L, which is based on geomagnetism technology, is chosen as the sensor for detection of parking spaces. It is with small dimension, easy installation, non-interfence of nonferromagnetic material, and high reliability. The data transmission and control programs were developed for three kinds of nodes. Through the test, the developed system is validated to meet the expected demands.
