摘　　要：详细阐述了一种带时间参数的信号采集方法的实现,此方案可广泛适用于如气象、电力、油田等对采集数据的时间要求比较严格、采集频率不高的场合。由于采用的GPS模块和AD转换芯片均是市场上常见的,使得整个方案具有成本低、可靠性好的优点。该方案已在研制的大气电场仪中得到成功应用,使整个设备的集约化程度大大提高。The realization of a data collection system is elaborated which takes time parameters. And it can be applied to fields strict to time of collecting datum but lower of frequency, such as weather, electric power, oilfield and the like. As the GPS and AD convert chip used are hackneyed in the market, this signal collection system has much lower cost and good credibility. It has been successfully applied in the electric mill produced by us, and simplifies the whole instrument enormously.
