摘　　要：针对声波换能器高温测试的控制过程庞杂、控制对象分散的特点,设计了以一台高性能笔记本电脑作为上位机、多个嵌入式系统为前端机的分布式控制系统。基于以太网技术,阐述系统在客户端/服务器(C/S)工作模式下,以网络通讯方式进行异种平台的数据传输方法,实现了系统的上位机和前端机之间可靠的数据通讯,解决了传统测试仪器多项功能集成困难的问题。声波换能器高温测试系统运行中的数据传输测试结果表明,此数据通讯系统数据传输延迟时间短、稳定,差错校验码校验正确,能够满足系统网络通讯的实时性要求。Aimed at the characterizations of high temperature test of acoustic wave transducer for many controlled objects and numerous jumbled control process, a distributed control system was designed. In the system, a high performance notebook PC is used as the upper computer and four embedded systems are used as the front ends. Based on Ethernet,： network communication was used to the data transfer among different computer platforms with the mode of Client/Server. In this way, the problem of traditional test instrument to integrate many functions was solved. The test resuhs show that the data transfer is characterized by short delay time, steady transmission and right cyclic redundancy check, and can satisfy the real time requirement of the high temperature test system of acoustic wave transducer.
