AI Technical Summary

Problems solved by technology

[0003] The existing traditional rain and snow sensing devices are all electronic sensing devices. The electronic components are affected by the wind, sun, and rain outdoors, which will accelerate the aging of the entire device, and the maintenance is frequent, and the long-term cost is not low; Sensing devices are easily affected by lightning in the open outdoors, and data loss will be caused by device damage and communication interference; some sensing components adopt movable structures (for example, such as tipping bucket rain gauges, water wheels for rainwater flow monitoring, etc. ), such parts are prone to wear or block and cause mechanical failure, which will affect the measurement accuracy, and the maintenance of such parts is more difficult

[0004] To sum up, the existing traditional rain and snow sensor devices are not suitable for the fields or uninhabited areas where the daily maintenance is poor, and there are technical blind spots for the monitoring of rain and snow in such working conditions; in addition, even in easy-maintenance Under the working conditions, the existing traditional rain and snow sensing device also has the problem of high long-term application cost
