针对现有燃烧驱动氟化氘(DF)化学激光器测控系统体积庞大、接线复杂等诸多不足,在分析化学激光器测控系统基本功能需求和运行特点的基础上,以PIC单片机为硬件核心,研制出一套采用电池组供电、测控指令与数据可无线射频或485总线传输、可由PC终端和安卓手持终端两种上位机控制的嵌入式智能测控系统。该系统具有采集流场参数数据、控制气体燃料供给时序、闭环调控燃料流量等功能。功能板测试实验结果表明,该系统可完全嵌入激光器系统中,具有体积小、接线少、重量轻、扩展性好、抗干扰能力强、数据安全性好等优点,应用前景良好,同时为化学激光器测控系统的紧凑化设计奠定了坚实的基础。

In order to solve the existing problems in the measurement and control system of combustion driven deuterium fluoride （DF） chemical lasers, such as the large system volume and complex wiring, an embedded intelligent measurement and control system is designed based on the analysis of the basic functional requirements and operating characteristics of chemical laser measurement and control system powered by a battery pack and using the PIC microcontrollers as the hardware device. The system can be controlled by a PC upper-computer and an Android hand-held upper-computer, which measurement-control instructions and data can be transmitted by the radio frequency wireless or 485 data bus. The intelligent measurement and control system has the functions of flow field data acquisition, supply control of different fuels according to the injection timing sequence, closed-loop control of fuelsr flow rates, and so on. The test results based on the function board show that this embedded intelligent measurement and control system has not only smaller volume, less wiring and lighter weight, but also good expansibility, strong anti-interference ability and reliable data security, which shows a good application prospect, and at the same time, lays a solid foundation for the compactness of the measurement and control system of chemical lasers.
