摘　　要：为实现远程激光功率的测量并保证数据传输的安全性,设计了一种非联网的无线激光功率计数据采集传输模块。该模块由三个部分组成:STM32数据采集模块、无线RS485透传模块和Qt上位机软件。其中STM32数据采集模块将探测器采集的电压模拟信号转换为数字信号,无线RS485透传模块负责STM32数据采集模块与PC端的数据通信,Qt上位机程序处理接收的数据并显示实时激光功率曲线。验证实验结果表明,在1 km传输距离下,该模块成功采集到完整的激光功率曲线,数据传输出错率为0。该模块实现了远距离、高速率的功率数据采集和传输功能,为后期无线激光功率计的研制工作奠定了基础。In order to achieve remote measurement of laser power and ensure the security of data transmission,a data acquisition and transmission module for non-networked wireless laser power meter is designed.The module consists of three parts:STM32 data acquisition module,wireless RS485 transparent transmission module and Qt host computer software.The STM32 data acquisition module converts the voltage analog signal collected by the detector into a digital signal.The wireless RS485 transparent transmission module is responsible for the data communication between the STM32 data acquisition module and the PC.The Qt host computer program processes the received data and displays the real-time laser power curve.The test results show that at a transmission distance of 1 km,the module successfully collected a complete laser power curve,with a data transmission error rate of 0.This module realizes long-distance and high-speed power data acquisition and transmission functions,and lays a foundation for the later development of wireless laser power meters.
