基于LabVIEW的航电开关测试系统设计

Design of Avionics Switch Test System Based on LabVIEW

设计了航电开关测试系统的信号处理电路和测控软件。通过采集电路对开关两端的电压信号进行采集,将采集到的信号经由中间处理电路的放大、隔离等处理后,通过RS232串口通信线在LabVIEW测控软件界面上进行实时显示。

The processing circuit and the measurement and control software of the avionics switch test system were designed.Through collecting voltage signals at both ends of the switch and amplifying and isolating them via the intermediate processing circuit,they were displayed at real time on the host computer interface via the RS232 serial communication line.
