Introduction to rainfall monitoring system

When studying meteorological factors, rainfall, as one of the important links, will change to varying degrees in a certain period of time, and the rainfall level will also increase or decrease, which will directly affect whether the water level of rivers, lakes, seas, reservoirs and rivers rises, endanger the growth, maturity, yield and health of crops, and indirectly affect urban waterlogging, mountain landslides, mud rock flows, mountain torrents and other secondary disasters, which are closely related to people's food, clothing, housing and transportation.

In this context, timely monitoring of rainfall changes can provide accurate, real and timely reference for flood prevention. The timely monitoring of rainfall changes has obvious impact on people's production and life.

As a high-tech rainfall monitoring equipment, the rainfall monitoring system can convert the change of rainfall into some signal and transmit it to the server, and then display it on the system platform through data list and other methods. It can realize the automation of rainfall observation when nobody is on duty, and send the information reflecting rainfall changes to the server in time through wireless transmission. The server automatically classifies, summarizes, and counts these information, and then displays them on the system platform in the form of data list or chart, providing browsing, querying, and exporting information for general users.

The rainfall monitoring system includes high-precision rainfall sensor, ponding sensor, remote automatic collector, background server system and mobile APP/web terminal. The remote automatic collector uses 4G full network communication to realize rainfall collection, ponding collection, automatic recording, automatic upload, historical data storage, over limit alarm, power failure alarm functions; The rainfall and ponding sensor sends the acquired rainfall and ponding information to the remote automatic collector; The collector sends the acquired rainfall ponding value to the background server through the 4G communication module; Finally, it will be sent to Android mobile APP and computer web terminal. The device displays the rainfall in real time and reminds in time. When the water level or rainfall exceeds the set limit value, the alarm device of the device will be triggered. At the same time, the system can automatically send information alarm to the management personnel to inform them to deal with it in a timely manner. It can achieve all-weather, long-term continuous online monitoring, and achieve the harsh environment of unattended.
