某型风洞DCS控制系统半模子系统的研制

The development of half-model subsystem in DCS control system on some model wind tunnel

在对实验模型的攻角控制中,使用可编程控制器PLC-200将常规半模控制与位置检测程序内置其中,通过EM277通讯模块,将该系统上挂于某型风洞PROFIBUS总线,使其升级为某型风洞DCS集散控制系统中的一个子系统,实现了某型风洞DCS系统中主控算机IPC对半模机构的远程控制与管理。

This paper puts the program of normal half-model control and that of location check inside the PLC-200 in pitching angle control to the experiment model,with EM277 communication module,it is connected with the PROFIBUS cable of some model wind tunnel and becomes a subsystem in DCS gather-scatter control system on some model wind tunnel,then it is fulfilled that IPC further control and manage the half-model subsystem.
