The stories that Lichun and the rainfall monitoring system have to tell
Today is the beginning of the spring, and there is still a full week before the New Year. As the Chinese New Year is relatively late this year, various agricultural activities kicked off immediately after the Spring Festival. In order not to delay agricultural production, this article will introduce a set of rainfall monitoring that monitors rainfall in real time. System, hope to help agricultural production.
Farmers say that "spring competes with the sun, summer competes with the time." The essence of spring competition is that the crops are sown in the early and late days of spring, and the future growth and harvest will be different. At the beginning of spring plowing, the soil needs to be plowed. However, the strips of soil that have just been plowed still have a certain amount of moisture and viscosity. The strips of mud should be raked up after drying for a day and a half. If you do not rake, the wind blows. If the sun is too long, the newly turned soil will dry out and form soil bumps. If the freshly plowed soil encounters rain before it can be raked, it will be troublesome. After the weather is clear, the rain-drenched soil will become as strong as iron bumps.
Although China's agriculture has begun to be gradually replaced by mechanization, if real-time changes in climate such as rainfall cannot be grasped, it will not only affect the quality of spring ploughing, but also leave hidden dangers for spring planting. I hope that all farmers can pay enough attention to rainfall monitoring.
Rain gauges are also called rain recorders, rain gauges, and rain gauges. They are conventional meteorological testing instruments. Meteorological departments use it to monitor and measure rainfall and rainfall intensity. Commonly used are siphon rain gauges, tipping bucket rain gauges and scales. Heavy rain gauge, etc. Because the tipping bucket rain gauge is easy to carry and install, and the data is relatively accurate, it is widely used in agricultural meteorological monitoring.
1. The composition 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 rain port, a water diversion funnel, a tipping bucket, an angle adjustment device, a level adjustment device, a level adjustment device, a reed pipe, etc.; the recorder It is composed of constant magnet steel, drain funnel, signal output terminal, control circuit board, etc.
2. The working principle of the
tipping bucket rain gauge: The working principle of the tipping bucket rain gauge is: rainwater enters the water receiver from the uppermost rain port, falls into the water diversion funnel, flows into the tipping bucket through the funnel mouth, and when the water accumulation reaches a certain height (such as 0.1mm), the tipping bucket loses its balance and overturns; the water is poured out, and as the rain continues, the tipping bucket will turn left and right. The contact switch will turn the number of tipping bucket flips into an electrical signal, which will be sent to the recorder, in the cumulative counter and self-recording clock. Read the precipitation data on the top, so that the rain process can be measured back and forth.
The composition of the
rainfall monitoring system The rainfall monitoring system is composed of a rainfall weather station, solar power supply system, and network communication technology.
**Rainfall weather station: **In addition to the tipping bucket rain gauge, the rainfall weather station can also choose to install wind speed and direction sensors or shutter boxes.
**Solar power supply system: **When the rain monitoring system is used in the field, forest fire prevention, mountain flood monitoring and other occasions where there is no mains power supply, it can be equipped with 60W solar panels and lead storage batteries for power supply. In a sunny day, the lead-acid battery can be fully charged in 7.5h, and the fully-charged lead-acid battery can work for seven days in continuous rainy and cloudy days.
**Network communication technology: **The rainfall monitoring system uploads data to the data center through wired, GPRS, Ethernet and other communication methods. 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; Supports 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. Historical data can also be downloaded, printed and exported to a computer, and stored as an EXCEL table file for easy research And check.
Spring ploughing and spring planting are very hard, but the farmers' friends are very comfortable. After all, it is a satisfaction to have land to cultivate, and to cultivate in the spring breeze and rain is the hope of the whole year. Waiting for a bumper harvest is a pleasure.
