基于Labview的液氧/煤油贮箱压力控制软件

Pressure control system based on Labview for liquid oxygen/kerosene vessel

介绍了液体火箭发动机地面试验推进剂贮箱压力控制系统的设计要点、系统组成和在RT实时系统环境中软件的开发过程。详细阐述了贮箱压力控制系统的工作原理、技术特点、系统组成机构,经过多次测试及地面热试车验证,成功实现了多路控制对象的集中控制。

The design requirements and system composition of propellant vessel pressure control system for liquid rocket engine ground test and the software development based on Labview under real time system were introduced in this paper. The principle of the vessel pressure control system, technology characteristics and the system framework were described in detail. Centralized control of multi-channel signals was obtained and was proved successful by ground tests.
