针对目前固体火箭发动机试验控制台向各个参试设备发送时统零点的精度和同步性差以及点火控制时序精度较低的问题；提出了以固态继电器板为测试系统控制执行机构，大功率固态继电器为点火控制机构，电流传感器为点火信号，采集装置为硬件基础，使用 VC＋＋6．0开发了基于 RTX 实时系统的点火控制软件，提高了当前发动机试验控制系统的时统零点和时序控制精度；通过测试某标准发动机对点火时统零点信息测试，精度均优于0．1ms。%In view of the solid rocket motor test console to each equipment sent system zero precision and synchronicity difference as well as ignition control timing accuracy low problem at present.Put forward by the solid state relay board for testing system of control actuators, high-power solid state relay for ignition control mechanism,current sensor for the ignition signal,collecting device for hardware based, the use of VC++6.0development of the control software based on RTX real time system,improve the motor test control system of zero and sequential control accuracy.By testing a standard motor ignition timing zero signal testing,the accuracy is better than 0.1ms.
