基于组态软件的投放器气密性试验台设计

Design of Air Tightness Test Bed for Launcher

投放器气密性试验台模拟机舱内外压力差,为投放器投放制造条件,并检查投放器的密封性能。投放器气密性试验台测控子系统以工业控制计算机为平台,扩展符合MODBUS协议的模拟信号采集模块和输入输出模块,基于组态软件开发测控软件,实时显示投放器的相关状态及其气密性试验台的气体压力和流量等。

Air tightness test bed for launcher simulates the pressure difference of the airplane cabin,creates favourable conditions for the drop of the launcher and checks the air tightness performance of the launcher.The measure&control subsysytem bases on the industrial personal computer,installs analog I/O module in accord with MODBUS protocol.The measure&control software is developed from configuration software,displays the status of the launcher,shows the air pressure and the rate of flow of the test bed in real time.
