灌区流量监测太阳能供电设计

Design for Solar Power Supply of Flow Monitoring in Irrigation Area

现代信息化生态灌区中监测调控灌区流量极为重要。灌区流量监测中设备供电依照水资源监测标准要求需配备备用电源,单一用蓄电瓶做备用电源使用寿命短,在供电环境复杂的灌区不能满足流量监测系统户外的供电要求。笔者设计一种基于太阳能的灌区监测系统供电电路。利用太阳能充电板实现设备在220 V市电与太阳能供电之间的切换,保证灌区流量监测设备在复杂环境下长时间稳定工作。供电系统在实现稳定切换的同时对蓄电瓶进行充电保护,使蓄电瓶长期处于浮冲状态,保证最长使用寿命。经过使用验证该供电系统能长期稳定工作并起到保护设备作用。

It is very important to monitor and control the flow of irrigation area in the modern information ecological irrigation area.In the flow monitoring of irrigation area,equipment power supply should be equipped with standby power supply according to the requirements of water resources monitoring standard,and the standby power supply is only used with a storage battery.The service life is short,and the irrigation area with complex power supply environment can not meet the power supply requirements of the outdoor traffic monitoring system.The author designs a power supply circuit for the irrigation area monitoring system based on solar energy.The switch between the 220 V power and solar power supply is realized by using the solar energy charging board,so as to ensure the long-term stable operation of the flow monitoring equipment in the complex environment.At the same time,the power supply system recharges the storage bottle at the same time,and keeps the storage bottle in the floating state for a long time,so as to ensure the longest service life.It is used to verify that the power supply system can work steadily for a long time and play a role in pr otecting the equipment.
