基于GPS/GPRS/RFID的车辆监控终端设计

Design of Vehicle Monitor Based on GPS/GPRS/RFID

针对物流管理中运输、装卸等环节对车辆监控、货物监测的需求,提出了一种基于C8051F040单片机、GPS定位、GPRS无线传输及RFID识别技术的物流车辆监控终端装置。该装置充分发挥C8051F040单片机高速、低功耗、接口丰富的优势,通过GPRS模块与监控中心进行高速通信,GPS和RFID技术的综合应用可以实现车辆定位、车辆控制、货物在途监测以及基于货单的装卸货监控等功能。本文详细阐述了系统硬件设计方案,以及GPRS、RFID相关程序的设计流程。

Based on Global Position System （GPS）, General Packet Radio Service （GPRS） and Radio Frequency Identification （RFID）, a logistic vehicle monitor terminal was proposed. With GPS module and RFID tag reader, the monitor can get position and goods information. Monitor ean connect to the center by the GPRS module. The center can implement goods monitor and vehicle scheduling. This paper describes hardware design and programming essentials in detail. GPRS module control method based on AT instruction set and RFID tags using method discussed in this paper can be used generally.
