摘　　要：土木结构抗震实验系统由电液伺服加载设备与数据采集仪两部分组成.加载实验机的控制数据保存在其控制器中,其它测试数据则保存在数据采集仪中.电液伺服试验机中加入数字命令控制模块,联机遥控触发数采仪的试验系统,将信号采集、程序计算和命令控制同步完成,加快了实验进程,解决了实验数据采集记录的不同步问题.以火电厂框排架混合结构拟动力实验为例,详细说明了基于数字命令控制实验系统联机运行的建立方法和试验流程.Civil experimental system consists of electric-hydraulic servo-controlled testing machine and the data logger with the test data stored respectively. With the digital command control module in servo controller, a exterior trigger signal is used to remote control the data logger, and the data recording synchronously were solved by on-line processing, which quickened the testing speed by making program calculation and command control completed simultaneously. The operation establishment method and test process based on digital command control for on-line test for hybrid structure of thermal power plant were described, which realizes the pseudo-dynamic test automatically.
