How does the tipping bucket rain gauge work? How does the tipping bucket rain gauge upload data?
Rain gauges are also called rainfall recorders, rain gauges, and rain gauges. They are the most basic meteorological testing instruments. Rainfall monitoring is an important task in agriculture, meteorology, water conservancy, construction and other industries. If excessive precipitation occurs, floods will occur. Disasters, landslides, mudslides and other natural disasters will cause huge economic losses to agricultural production, while too little precipitation will increase the contradiction between domestic water, farmland irrigation water and factory water, resulting in soil salinization, desertification, etc. And so on, it will also bring huge economic losses to agricultural production and other fields.

Meteorological departments use rain gauges to monitor and measure rainfall and rainfall intensity. Commonly used are siphon rain gauges, tipping bucket rain gauges, and weighing rain gauges. In this article, we mainly talk about the working principle of the tipping bucket rain gauge and how to upload data.

The working principle of the tipping bucket rain gauge:

The tipping bucket rain gauge is a remote rain measurement instrument composed of a sensor and a signal recorder. The sensor consists of a water receiver, an upper tipping bucket, a measuring tipping bucket, a counting tipping bucket, Reed switch, etc.; recorder is composed of counter, recorder, self-recording clock, control circuit board, etc.

Rainwater enters the water receiver from the uppermost water-receiving port, falls into the water-receiving funnel, and flows into the tipping bucket through the funnel mouth. When the accumulated water reaches a certain height (such as 0.01 mm), the tipping bucket loses balance and overturns . And every time the bucket dumps, the switch turns on the circuit and sends a pulse signal to the recorder. The recorder controls the self-recording pen to record the rainfall, so that the rainfall process can be measured back and forth.

The tipping bucket rain gauge has a rain bearing caliber of 200mm. There are two types of 485 signal output and pulse signal output. The core component of the tipping bucket adopts a three-dimensional streamline design, with a drooping arc surface guide tip, and uses imported high-quality Made of transparent material, beautiful appearance, with the function of self-cleaning dust and easy cleaning, making the tipping bucket more smooth; the tipping bucket sleeve adopts an integrated rotary positioning structure design, no need to adjust the distance between the two sleeves, and it is very easy to install on site. convenient.

How to upload data for tipping bucket rain gauge?

The tipping bucket rain gauge, solar power supply system, and network communication technology form an intelligent rainfall monitoring system, which records rainfall data in real time to ensure that the data will not be modified. It provides the original original Rainfall data.

The intelligent rainfall monitoring system uploads data to the data center through communication methods such as wired, GPRS, and Ethernet. The system can track and record the whole process, integrate data collection, recording, and storage, and has remote diagnosis and control functions. When the monitoring station is in sleep state, the center can wake up the monitoring station at any time to collect data, read data, or modify configuration information; Support multiple central working modes.

It is more convenient to view data through the cloud platform, such as curve viewing period rainfall, daily rainfall, monthly rainfall, and annual rainfall. You can also download and print historical data, and you can also export to a computer and store it as an EXCEL table. Documents to facilitate research and inspection.

The rain gauge has been in an outdoor environment for a long time, and it is generally cleaned once every one to three months; wipe the inner wall of the rain port gently with a soft cloth to keep the rain port clean. If there are foreign objects such as leaves in the rain port, clean it up in time , Keep the waterway unobstructed; when not in use for a long time, cover the ring mouth of the instrument to protect the rain-bearing mouth.

The distribution of precipitation in my country is uneven in time and space, and local areas are prone to floods and droughts. By using rain gauges to understand the precipitation in a region, it helps us to better arrange production and life. At present, tipping bucket rain gauges are widely used in applications such as meteorology, agriculture, industrial automation engineering, intelligent building systems, workshops, warehouses, museums, laboratories, and greenhouses, bringing convenience to various fields.
