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 results 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.
