摘　　要：为便于仪器的网络化管理,对当前仪器仪表组网方式进行了研究,设计了支持多种接口的仪器仪表网络代理。仪器设备通过网络代理可以接入网络与控制主机互联,代理通过高速以太网仪器协议(HiSLIP)与主机通信,将主机所传达的信息通过虚拟仪器软件结构框架(VISA)接口转发给仪器设备,从而实现上位机对仪器设备的远程控制。实践结果表明,主机与仪器通信效果良好。In order to facilitate networked management for instruments, the currently existing networking modes of are studied, and the network agent supporting instrumentation with multiple types of interfaces is designed. Through network agent, instruments and devices are able to access the network and interconnect with the host computer; the agent communicates with the host computer using Ethernet based high speed LAN instrument protocol HiSLIP; and forwards the information transmitted from host computer to instruments and deviees via VISA interface ; thus the remote control from host computer to instruments and devices is implemented. The practice indicates that the communication between host computer and instrumentation is excellent.
