摘要
随着工业生产、气象监测等领域对环境参数精准度要求的不断提高，风速的实时测量与异常预警对保障生产安全、优化作业效率具有重要意义。传统的风速测量方式多依赖人工读取机械风速仪数据，不仅效率低下、响应滞后，还存在测量误差大、无法及时预警等问题，难以满足现代化场景对风速监测的实时性与可靠性需求。
基于 STC89C52 单片机的风速测量系统，整合了风速检测模块、按键、显示模块及声光报警装置，实现了环境风速的自动化监测与异常预警。系统核心功能包括：通过风速检测模块实时监测当前环境风速，当风速大于设置的最大值时，触发声光报警装置提醒；支持通过按键设置风速最大值，满足不同场景的监测需求；通过显示模块实时显示当前风速及设置的最大值。
该系统的实现，有效提升了风速测量的自动化水平，减少了人工干预，确保了风速数据的实时性与预警的及时性，为工业生产、气象监测等场景提供了简单、可靠的风速监测解决方案，同时为同类环境参数测量设备的研发提供了参考，具有一定的实际应用价值。

ABSTRACT
With the increasing requirements for the accuracy of environmental parameters in industrial production, meteorological monitoring and other fields, real-time measurement and abnormal warning of wind speed are of great significance for ensuring production safety and optimizing operation efficiency. Traditional wind speed measurement methods mostly rely on manual reading of data from mechanical anemometers, which are not only inefficient and slow in response, but also have problems such as large measurement errors and inability to warn in a timely manner, making it difficult to meet the needs of modern scenarios for real-time and reliable wind speed monitoring.
The wind speed measurement system based on STC89C52 single-chip microcomputer integrates a wind speed detection module, buttons, a display module and an acousto-optic alarm device, realizing automatic monitoring and abnormal warning of environmental wind speed. The core functions of the system include: real-time monitoring of current environmental wind speed through the wind speed detection module, and triggering the acousto-optic alarm device to remind when the wind speed exceeds the set maximum value; supporting the setting of the maximum wind speed through buttons to meet the monitoring needs of different scenarios; real-time display of the current wind speed and the set maximum value through the display module.
The implementation of this system effectively improves the automation level of wind speed measurement, reduces manual intervention, ensures the real-time performance of wind speed data and the timeliness of early warning, provides a simple and reliable wind speed monitoring solution for industrial production, meteorological monitoring and other scenarios, and also provides a reference for the research and development of similar environmental parameter measurement equipment, with certain practical application value.
