摘要
针对长征六号运载火箭动力测发控系统射前仿真测试需求,结合短周期快速发射及方舱操作的特点,设计了一种仿真测试平台;该测试平台使用电气信号模拟动力配气台阀门、压力传感器及箭体连接器硬件接口信号,形成硬件接口层;采用软件模拟配气台工作原理,仿真箭体连接器通断,并模拟基地加注间通讯系统与动力测发控系统进行信息交互,形成软件模型层;硬件接口层与软件模型层之间通过RS422总线和PC104总线连接,实现仿真测试平台的模块化和组合化设计;该仿真测试平台为长征六号运载火箭动力测发控系统提供了闭环测试环境;实际情况表明,该仿真测试平台可覆盖动力测发控系统的全部工作状态,满足短周期快速发射的测试需求,提高了动力测发控系统仿真测试的效率。
Aiming at the requirement of pre -launch simulation test of CZ-6 Power Control and Testing system,A simulation test plat-form is designed according to the characteristics of exhort -period rapid launch and shelter operation. The test platform uses the electrical sig-nal that simulate the power distribution valve, pressure sensor and connector hardware interface signal to form the hardwusing of software simulation of the working principle of the gas distribution platform,ro cket's connectors, and the base filling communica-tion to form the software model layer. The hardware interface layer and the software model layer are conncected by the RS422 busand the PC104 bus to realize modularization and combined type. The test platform composes a closed -loop test environment with CZ -6 power con-trol and testing system. The pratice shows that all work status of CZ -6 Power Control and Testing system are met and the test efficientcyis improved.
