摘要
介绍了一种新型列车预警器的研制。该仪器由主站和分站构成,均使用单片机微控制器来控制。分站通过磁钢传感器采集列车速度和方向信号,通过无线收发模块与主站通讯。主站处理接收到的信息并实现数据存储、通讯、检索和基于ISD4004芯片的语音播报提示等强大的功能。在硬件电路设计中,分站系统主要考虑实现低功耗的问题,主站则采用了混合电源设计和多机通讯等独特的技术。该仪器经9个月的运行,性能可靠。
The study of a new wireless alarm instrument for railway safety was introduced. This instrument was composed by main station and subject station which both used single-chip microcomputer as microcontroller. The subject station can test the speed and orientation of the train and send the message to the main station by wireless module. The main station realized the function of receiving the message, saving data, communication, searching, broadcasting by ISD004 and so on. The subject station considered the realization of low power consumption, the main station used the mixed power supply and the multi-communication technology. The instrument has been operated for nine months, and it is reliable.
