| Abstract: | The optical power of real-time monitoring system is designed on Cortex-M3 32-bit ARM core STM32F103ZE, and the designing principles, implementation, hardware and software structure are given. This ar- ticle describes the monitored light transferred into digital signal by photoelectric conversion circuit, logarithmic am- plifier and AD converter circuit. Then the digital signal is sent to the control unit via field bus for data transmission through GRPS communication module to realize the real-time automatic monitor to the communication cable. Addi- tionally, the design has the advantage of stability, reliability and easy expansion |
