基于STC单片机的气象监测系统的设计与应用

为了较精准地检测多种气象要素,设计了基于STC单片机的气象监测系统。该系统采用光伏离网户用系统进行供电,以STC15W单片机为核心,利用空气质量传感器模组、风速风向传感器以及温湿度传感器对相关气象信息进行在线实时监测;通过串口通信、模数转换、单总线通信读取相应传感器数据;以原厂提供的数据转换公式及滤波算法,换算出各个传感器监测的气象数据,并进行显示。测试结果表明,该系统能够有效监测多个气象要素信息,且稳定性良好,实时性高,监测精度高。

Design and Application of Meteorological Monitoring System Based on STC Single Chip Microcomputer

Absract:In order to accurately detect various meteorological elements,a meteorological monitoring system based on STC single chip microcomputer is designed. The system uses photovoltaic off-grid household system for power supply,STC15 W single chip microcomputer as the core,and uses air quali ty sensor module,wind speed and wind direction sensor and temperature and humidity sensor to monitor the relevant meteorological information in real time online.Read the corresponding sensor data through serial port communication,analog-to-digital conversion and single bus communication. With the data conversion formula and filtering algorithm provided by the original factory,the meteorological data monitored by each sensor is converted and displayed. The test results show that the system can effectively monitor multiple meteorological information,and has good stability,high real-time performance and high monitoring accuracy.
