摘　　要：紊动水流经常会引起闸门产生较大的振动,容易造成闸门构件的疲劳,对水电站的安全生产极为不利。介绍了一套自行研制开发的以89C51单片机为核心器件,以16路集成数据采集芯片MN7150-16为前向通道,并配有适宜远传的RS-485为串行通信接口的闸门振动测试仪,给出了单机测试过程中的多点数据采集问题的硬件方案,并提供了水情复杂时多机同时启用的软件解决方案以及振动测试仪与计算机数据库的通信联络方式。Turbulent flow induces vibration of sluice, which will derive safety problem of hydropower plant because of weariness of sluice components. The article introduces a set of test instrument for sluice vibration, and offers a kind of way to collect multi-node data with hardware and software for the test. The test system has a CPU of 89C51,which is developed by the authors, a 16 circuits integrated data acquisition chip MN7150-16, and sluice vibration testing meter of serial communication interface RS-485 for remote data transmission. The software scheme for multi-computer start at complicated hydrologic regime and communication between vibration testing meter and computer database are also provided.
