摘　　要：在电力系统信号的测量中,常需对多路信号进行同步采集,而基于常规采样芯片的数据采集模块通常存在系统复杂、体积大、非完全同步采样等不足。MAXIM公司推出的MAX15 5是一种高速、8位8输入通道的同步采样A/ D转换器,非常适合电力系统信号同步测量的要求。详细介绍了基于MAX15 5 A/ D转换器和AT89S5 1单片机的同步数据系统的硬件和软件的设计方法。实验结果表明该系统不仅采样精度高,而且能实现完全同步采样。Usually it is necessary to simultaneously sample several channel signals in power system, but the data sample module based on normal A/D converter is complex, big and cannot realize complete simultaneously sampling. MAX155 of MAXIM is a high speed, 8 bit, 8 channel simultaneously sampling A/D converter, which is fit for the power system measure′s demand. This paper introduces a hardware & software design method for a synchronous data collecting system which based on MAX155 and AT89S51. Test result proves that this system not only has high sampling precision, but also can realize absolute simultaneously sampling.
