摘　　要：设计了一种基于Cortex-M3内核的32位ARM产品STM32F103ZE的光功率实时监测系统,并给出了设计的原理、实现方法及软硬件结构。介绍了被监测光分别通过光电转换电路、对数放大电路、A/D转换电路转换成的数字信号通过现场总线传递给主控单元,再经GPRS通信模块进行数据传输,可形成对通信光缆的实时自动监测。该设计具有可靠性高、方便扩展等优点。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
