基于Zigbee和GPRS的无线公交考勤管理系统

目前各城市公交公司主要采用人工打卡方式作为公交车考勤的主要手段，操作起来既不方便又费时。本文提出一种基于Zigbee技术和GPRS的无线智能公交考勤系统。该系统通过Zigbee无线传输技术实现车载终端与考勤打卡机通信，由打卡机记录下公交车的车号和时间，再通过GPRS技术传输到管理中心，实现对运行中的公交车进行监控和定位，具有方便省时，简单可靠，成本低等优点。

Wireless Bus Check System based on Zigbee and GPRS

Now in many cities bus check is made by hand, which is time-wasting and inconvenient, This paper presents a wireless bus check and management system based on Zigbee and GPRS technology. The system achieves communication between check machine and onboard unit by Zigbee technology, records the ID and arrival time of buses and passes on the information through GPRS network to the center of management to supervise the buses in service. This system is automatic, convenient, simple, reliable and low cost.
