摘　　要：针对目前已有的测控系统实时性差、准确性不够、操作不便等缺陷提出了基于μC/OS-Ⅱ系统的HISLIP(High Speed LAN Instrument Protocol)远程测控代理的设计方案。该系统底层硬件采用恩智浦公司的LPC1768微控制器,操作系统采用可靠性、移植性和安全性较好的μC/OS-Ⅱ操作系统;网络层基于TCP/IP(Transmission Control Protocol/Internet Protocol)协议。传输层以客户端服务器(C/S)模式实现HISLIP协议,并将其作为整个测控系统的通信协议。设计实现了以HISLIP协议为主的仪器通信的软件系统,在对代理的软、硬件的设计、编程和测试,实现了远程测控通信的功能模块的实时性、准确性、操作便利的设计要求。Aiming at the shortcomings of the existing measurement and control system,such as poor real-time performance,insufficient accuracy and inconvenient operation,the design scheme of HISLIP remote measurement and control agent based on μC/OS-Ⅱ system is proposed. The bottom layer of the system uses NXP LPC1768 microcontroller,which uses the μC/OS-Ⅱ operating system with high reliability,portability and security. The network layer is based on the TCP/IP(Transmission Control Protocol/Internet Protocol)protocol. The transport layer implements the HISLIP protocol in the client server(C/S)mode and uses it as the communication protocol for the entire measurement and control system.The software system of instrument communication based on HISLIP protocol is designed and implemented. In the design,programming and testing of the software and hardware of the agent,the real-time,accuracy and convenient design requirements of the function module of remote measurement and control communication are realized.
