| 目前，贵州省常规气象站的供电能源主要是依靠太阳能板的光生伏特效应，由于站点的供电容易受到日照、环境、电池性能等各方面因素的影响，因供电系统引起的故障已占所有故障的60%左右。为了实时有效地对站点的供电状态进行监控，该文主要介绍了如何通过AT89C52系列单片机研制自动站供电状态监控系统，基于单片机硬件开发，实现对常规气象站太阳能板、蓄电池、负载端电压进行三路采集，并集成温湿度传感器采集机箱内部温湿度数据。基于GPRS通信原理进行数据传输，在设置的阈值下，系统会对采集到的数据进行分析，通过微信客户端信息推送的方式通知相关保障人员，第一时间获取故障信息。此项设计实现了常规气象站供电状态的自动化监控报警功能，对提高站点的数据传输率起到积极的促进作用。 |

| Abstract: |
| At present, the power supply of conventional weather stations in our province mainly depends on the photovoltaic effect of solar panels. As the power supply of stations is easily affected by sunlight, environment, battery performance and other factors, the faults caused by power supply system have accounted for about 60% of all failures. In order to monitor the power supply status of the stations in real time and effectively, this paper mainly introduces how to develop the automatic stations power supply state monitoring system through the at89c52 series single chip microcomputer. Based on the hardware development of the single chip microcomputer, it realizes the three-way acquisition of the solar panel, battery and load terminal voltage of the conventional weather stations, and integrates the temperature and humidity sensor to collect the temperature and humidity data inside the power cabinets. Data transmission is based on GPRS communication principle. Under the set threshold, the system will analyze the collected data, inform relevant support personnel through wechat client information push, and obtain fault information at the first time. This design realizes the automatic monitoring and alarm function of the power supply state of the conventional weather stations, and plays a positive role in improving the data transmission rate of the stations. |
