活动发射平台环境监测系统设计与实现

Design and Implementation of Environmental Monitoring System for Mobile Launching Platform

为解决以往发射平台上模拟仪表人工读取记录效率低下,无法远程监控且不能获取平台执行任务前后监控点关键数据的问题,提出了基于分布式远程监控技术的环境监测系统设计方法。采用分布式前端控制箱获取各传感器信号,设计双点双线的电气连接方法完成前端测控箱与信号转接箱之间的信号传输;使用冗余热备的CompactRIO终端进行实时系统下的数据采集、保存、阈值判断与报警输出;基于TCP/IP协议的前端上位机采用了模块化参数配置、区域数据回放的方法,实现实时曲线显示、数据库读写及历史数据回放等功能。采用了抗振及耐盐雾等防护技术,通过了发射平台各试验及发射任务的检验,为活动发射平台日常调试及执行任务提供了及时可靠的环境数据。

An innovative approach of monitoring relying on distributed and remote technology is proposed, in order to solve the problems of inefficiency on manual record, un-remote monitoring and key data losing between executing the task based on analog instrument in the mobile launching platform. Sensors signals are acquired with the distributed front-end control box, and the electrical connection method of double point double wire is designed to complete the signal transmission between the front-end control box and signal transfer box. The main control box is applied based on hot backup in CompactRIO to accomplish data acquisition, data storage,threshold judgment and alarm output in the condition of real-time operating system. The front upper machine based on TCP/IP protocol achieves the functions such as real-time curve display, database read and write and historical data playback, with the method of flexible parameter configuration and specified district data playback. The technologies of anti vibration and anti-corrosion are promoted, which is carried out by the tests of mobile launching platform and the rocket launching mission. It provides the reliable data of the mobile launching platform in the case of routine debugging and task execution.
