MPX770数据采集系统的功能扩展——对多路模拟信号进行分时采集方法研究

Extension of Functions of MPX770 Data Acquisition System——Study of TDM Data Acquisition of Multiple Analog Signals for Onboard Quad-Redundant ACT Computers

介绍了MPX770数据采集系统770-0410热电偶/压力扫描寻址和信号调节器板卡,如何通过加装外围芯片,对其功能加以扩展,从而完成了对机载四余度电传计算机多路模拟信号的分时采集。

The card 0410 of the data acquisition system of MPX770 is introduced. This is a thermocouple/pressure scanner addresser and signal conditioner card. The extension of its functions by adding chips for the application of time division multiplex（TDM） data acquisition of the multiple analog signals is presented.
