| Abstract: | The lower computer system based on 8051single-chip microprocessor is presented in the transient optical signal detec-tion 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-collec-tion of the multi-channel analog input, the data acquisition in-terface circuit, and the watchdog circuit. |
