摘　　要：在火箭动力系统试验中,需要实时监测、显示和传输地面工艺系统和箭上状态参数。主要阐述了采用上下位机控制模式设计的工艺参数监视系统,介绍了系统硬件和软件设计。上位机硬件包括工控机和采集板卡,以LabVIEW语言开发软件设计,构建工艺状态总图;下位机采用PXI控制系统,加载采集板卡信息,通过光纤以太网与上位机进行通信。该系统监测参数达到300路,数据每100 ms更新一次,在多次型号动力试验中得到验证,能够准确地实现试验状态参数远距离采集、传输和显示,提高了试验安全性。In rocket propulsion system test, it display and transmission of ground process system parameters monitoring system is described, which is necessary to perform real-time monitoring, and state parameters of the rocket. A process takes the control mode of upper and lower computers. The system hardware and software design method is introduced in detail. The upper computer is composed of IPC and acquisition card, and takes LabVIEW language to develop the software and structure the general drawing of process state. The lower machine involves with PXI control system and acquisition cards, and communicates with the upper computer through fiber Internet. This system can monitor 300 parameters and update data every 100 ms. It was verified in many types of rocket propulsion tests. It can accurately achieve remote acquisition, transmission and display of test condition parameters. Therefore, the test security was improved.
