摘要
城市繁华地段的地面停车位(少于128个停车位)的管理问题一直没有得到很好地解决;文章介绍了一种基于Modbus通讯协议的地面停车位的智能管理系统的功能和方案设计;文章所设计的系统主要由PC机(主机)、RS485总线网络、车辆检测器、车位锁控制器(从机)和车位锁组成;文章详细论述了车位锁控制器抗干扰性能的硬件设计、及该系统中主机和从机的软件设计思路。利用RS485总线的分布式数据采集和控制系统,具有设备简单,价格低,能进行较长距离的通信的特点,使地面停车位的管理实现自动化和网络化。
The manager of parking space on the ground in prosperous city has not been solved effectively. The paper detailedly introduce the functional and conceptual design of small intelligent parking system on the ground based on Modbus network. The system is mainly corn posed of host computer. RS485 bus network, vehicle detector, collecter of parking lock （slave MCU） and parking lock. The paper pres ents the hardware design of microcontroller about how to ensure stability of system, as well as software design methods of single--chip and host computer. The RS485 bus has the advantage of distributed data acquisition and control system, simple equipment, low price and long distance communication features, which make ground parking manangement automation and networking.
