摘要
以STC89C52作为系统控制器,远程PC机作为上位机,使用GTM900C作为系统的GPRS模块完成数据的无线传输;用户可通过手机短信获取远程数据,也可通过PC机上的监控界面获取数据和交通灯当前信息;系统实现了数据的稳定传输,准确显示,实时性强,为偏远地区的交通灯检修维护提供了一种方便的途径,具有很强的实用价值。
The design of the hardware architecture and software of the traffic lights remote data acquisition system was introduced. The system made use of STC89C52 as the controller, employed remote PC as a window for the operation, and relied on GTM900C as the GPRS module, to realize the wireless reporting oi data. Users could extract remote data via not only short message service but the monitoring inter- face of remote PC as well. The data is transmitted steadily by this system which can displayed exactly in a real--time environment, the sys- tem shows a strong practical value by providing a convenient way for overhauling the traffic lights in some remote area.
