摘要
介绍了基于2.4GHz射频芯片nRF2401的公交车辆运营管理系统的组成,分析了STC89LE51RC与nRF2401接口电路及其软件设计的方法,讨论了车载终端、站台终端和总站终端3部分的工作原理.其中站台终端为车载终端提供识别的标签,使车载终端能准确记录车辆到站信息,总站终端完成了对运营车辆的调度及行程信息的接收与处理,并上传给PC机,从而组成了一套经济实用的智能公交车辆管理系统.
It is introduced that the configuration of a Intelligent supervisory system for buses, based on 2.4G radio frequency chip nRF2401. The method of the hardware interface between wireless transceiver module nRF2401 and STC89LES1RC and software design is described in detail. The operating principle of vehicle carries terminal, platform terminal and terminus terminal is analyzed. The platform terminals provide a electronic label for the vehicle carries terminal so that the vehicle carries terminal could exactly record the information when the bus reaches the station. Then the terminus terminal deals with the bus according to the information submitted by nRF2401 and uploads the information to personal computer. Such an economical practical management system is worth applying widely.
