数据采集监测计算伴随着微型计算机技术的快速发展，通过计算机处理，系统将采集的模拟信号转变成数字信号，得出数据，这些采集到的实时数据反映着不同的运行状态，并可以接收运行需要发出的各种命令。在各个领域中，不论是简单到复杂还是从表面到深入，数据采集系统的身影几乎无处不在，所以本课题的研究有着广阔的前景和经济价值，自二十世纪50年代到70年代以来，人们见证了数据采集系统的诞生与发展，从初步认可到逐渐分类，随着微型机的反正也诞生了许多性能优良的数据采集系统，但是在计算机普及之后，数据采集系统发生了巨大发展，然而数据采集系统需要的是不断地测试和完善系统的各项功能，如实时采集、进行记录、反应故障等，整个性能的优劣将受到数据采集的性能特点直接影响，足可见数据采集系统的重要性，因此对于数据采集系统需要不断完善和提升，是今后发展的一个主要方向[1]。(The ongoing developing of information technologies, in many areas, such as communication, control and monitoring, etc., the signal processing technology is becoming more and more widely applied to computer, the analog acquisition and processing in modern industrial control and research. The reliable operation of power system substation, especially the problem of remote monitoring unmanned substations, the merits of the entire property will be subject to the performance characteristics of the data collected directly affect, enough to see the data the importance of the system of acquisition.)
