公交副站无人调度系统设计

Design of No Scheduling System in Deputy Station

为安全、高效调度城市公交系统中有限的公交车辆,开发了一种可替代人工调度、降低运营成本的公交副站调度系统。该系统使用nRF24L01无线射频芯片作为无线收发模块,以单片机STC89C51RC作为微处理器,构成地面基站与车载节点。阐述了系统的硬件结构和软件设计,并对多路公交车进站时的身份识别和发车时间的次序安排问题进行了研究。结果表明,该系统可对到站的多路公交车快速登记,并提供发车时间,提高了公交系统的运营效率。

In order to dispatch the limited public transport vehicles in the urban public transport system safety and high efficiency,a deputy station bus dispatch system of alternative to manual scheduling and reduce operating costs is developed in this paper.The system uses the wireless RF transceiver chip nRF24L01 as a wireless module,and the STC89C51RC is used as the microprocessor.It constitutes the ground base station and vehicle mobile node.The hardware structure and software design are described,and the multipath buses stops identification and departure time sequence arrangement problem is studied.Results show that the design could provide the service of associate a quick registration for the buses in deputy station,and provide the departure time,improve the operation efficiency of the public transport system.
