摘　　要：论述了空间瞬态光信号探测系统中以单片机8051为核心的下位机系统。主要介绍了空间瞬态光信号的频率特性和下位机系统功能。下位机硬件电路设计中主要包括多路模拟输入采集模块,能量信号采集接口电路,看门狗电路。试验证明下位机系统可以满足系统探测要求。The lower computer system based on 8051single-chip microprocessor is presented in the transient optical signal detection system. In this paper, the lower computer system is mainly introduced in two parts ,the frequency analyze of the transient optical signal and the function of the lower computer system. The design of hardware circuits mainly contains the data-collection of the multi-channel analog input, the data acquisition interface circuit, and the watchdo~ circuit.
