摘要
针对当前城市出租车打车方式存在的不足,研发了基于无线网络的出租车订车调度系统.以GPRS MO-DEM、MCU等电子器件为核心,设计了出租车呼车端;应用Winsock控件实现了出租车调度中心与呼车乘客、出租车之间的通讯;应用地心空间直角坐标转化公式计算呼乘客和出租车的直线距离.在移动网络、互联网支持下,出租车车载端、呼车端、乘客手机、调度中心组成系统,为乘客订车提供服务,可以大幅减少出租车的空驶里程,节能减排.系统建立信用记录机制,可对出租车司机和乘客双方起到行为约束作用,减少呼车失败事件发生.
In view of the problems existed in catching taxi, the taxi reservation and dispatching system based on wireless network was established. Taxi calling terminal was designed with the core of GPRS MODEM, MCU and other electronic devices. Winsock control was used to realize the communication between dispatc- hing centre and passenger and taxi. The straight-line distance between calling passenger and taxi was calcu- lated by using formula of geocentric spatial rectangular coordinates. A system was formed by taxi terminal, calling terminal,moblie phone of passengers and dispatching centre under the support of mobile network and internet. It would provide service for taxi reservation, reduce mileage of empty driving greatly and pro- mote energy saving and emission reduction. Through the establishment of credit recording mechanism, the system could have some restriction effect on taxi driver and passenger and reduce failure event of catching taxi.
