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 of data. Users could extract remote data via not only short message service but the monitoring interface of remote PC as well. The data is transmitted steadily by this system which can displayed exactly in a real-time environment, the system shows a strong practical value by providing a convenient way for overhauling the traffic lights in some remote area. 
