摘要
核聚变装置HT-7U对极向场电源控制实时性要求特别高,必须在一个控制周期(1m s)内完成对12套电源设备的通信、反馈控制、采集、测量等闭环控制环节的操作。该系统利用了QNX平台的微内核实时性。同时为了增强人机界面的友好性,采用W indows系统作为操作平台。本文描述了在QNX和W INDOW S不同操作系统之间的一种跨平台网络通信。实践表明基于TCP/IP协议,利用SocketAPI建立的套接字在两种操作系统之间进行通信是完全可行的,而且是高效的。
The nuclear fusion device-HT-7U given extremely requirements for real time response ability of poloidal field power supply control system. It must implement communication, feedback control, data acquisition, and measurement within a control cycle (1 ms) on 12 set power supply sub-systems devices. It should use the QNX OS high neutrino kernel realtime, and for enforcing the friendly of man-machine interface,we use Windows as operate flat. This paper describes network communication between QNX and Windows. The practice shows that the communication on network between the two operate systems is entirely feasible and high efficiency,with the socket built on socket API based on TCP/IP.
