摘　　要：本系统以PIC24FJ128DA110为核心芯片实现了对全固态激光器工作过程中操作信号和保护信号的种类、发生时间,驱动电源电流反馈值以及激光功率反馈值等信息的记录;并应用Microchip提供的USB嵌入式堆栈和I2C串口通信将存储在EEPROM中的数据信息以文本格式写入USB闪存驱动器中。本系统方便了对全固态激光器操作流程的实时监控,加快了全固态激光器系统的故障排除和修复;为激光器和控制系统的改进设计提供了数据依据。本系统包含实时时钟模块、ADC模数转换模块、EEPROM数据存储模块、USB数据通信模块等。A real time performance monitor system, which has a PIC24FJ128DA110 as the main microprocessor, has been suc- cessfully designed to record the type of operation and protection signals, the time of event, the feedback value of the current of driv- ing power and the feedback value of laser power. By saving the data to USB flash driver in text format with Microchip USB stack and I2C serial communication protocol, this system is very convenient for monitoring DPL （Diode Pumped solid state Laser） and thus fa- cilitate the recovering of a malfunction DPL from its failure. It can also provide data for optimizing design of laser and its control sys- tem. The system includes RTCC module, ADC module, EEPROM data storage module, USB data communication module etc.
