摘　　要：混合是固体火箭推进剂制造过程中的一个关键工序,需在线测量桨叶上的压力信号。为此,设计并实现了混合机桨叶状态的在线检测系统,对实现过程中的若干关键技术进行深入研究,系统通过了现场联调。最后对测试系统设计过程中存在的不足进行全面分析,对今后改进的方向,特别是采集速度的提高问题进行了探讨。Mix is a key step during the producing course of the propellant. It is very important for the mixture machine to make real-time pressure measure of blade condition. An on-line monitoring system was designed and realized, and some key technologies of system were discussed simultaneously. This system was tested in the lab, and was utilized successfully in the factory. At last, the deficiency of the test system was analyzed, and some existed questions, especially the acquisition speed, were discussed.
