In order to better understand the changes in agricultural meteorology and help us develop agricultural production better by monitoring the changes in meteorology, more and more meteorological instrument systems are applied to the monitoring of agricultural microclimate environment. The weather monitoring system is such an automatic monitoring system with comprehensive weather observation, which can realize comprehensive weather monitoring and early warning, and is widely used in environmental protection, agriculture and forestry, meteorology, storage, scientific research and other fields.

1. Comprehensive weather monitoring

The meteorological monitoring system can automatically monitor conventional meteorological elements such as air temperature, air humidity, soil moisture, soil temperature, wind speed, wind direction, rainfall, and light intensity. The system is mainly composed of three parts: sensors, remote monitoring unit, data storage and processing software system. It can automatically collect weather monitoring data and transmit it to the server of the weather monitoring center through the GPRS wireless network platform. The staff can learn about it without leaving home. Statistics and analysis of real-time weather monitoring data from various weather monitoring stations are carried out online.

2. Weather warning

The meteorological monitoring system can give full play to the effects of meteorological monitoring and early warning, effectively play the role of the first line of defense for meteorological disaster prevention and mitigation, and comprehensively strengthen the construction of disaster prevention and mitigation capabilities. Based on the monitoring data information provided by the meteorological monitoring system and online analysis, relevant agricultural departments can timely understand the changes in agricultural microclimate, predict the occurrence of various meteorological disasters in advance, and take effective measures to avoid disaster losses to the greatest extent, thereby contributing to agricultural production and agriculture. Environmental research, crop improvement, crop phenological monitoring, pest control and other related production management work provide corresponding scientific data and decision-making basis.

The weather monitoring system has beautiful appearance and powerful functions. It is an intelligent weather system product, which can be widely used in agricultural production, scientific research and standard measurement. It is an important guarantee for modern agricultural scientific research, production, and the development of high-quality and efficient agriculture.

Pneumatic Valve

Pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast. The fastest switching speed is 0.05 seconds / time, so it is usually also called pneumatic quick cut-off ball valve. Pneumatic ball valve is usually equipped with various accessories, such as solenoid valve, air source treatment triplet, limit switch, positioner, control box, etc., to realize local control and remote centralized control. The valve can be controlled in the control room without running to the site or high altitude and dangerous areas for manual control, which saves human resources, time and safety to a great extent.

The pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rotating torque. The completely equal inner cavity of the valve body provides a very small resistance and straight flow channel for the medium. It is generally considered that the ball valve is most suitable for direct opening and closing. The main feature of the ball valve is its compact structure and easy operation and maintenance. It is suitable for general working media such as water, solvent, acid and natural gas, as well as media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses the circular butterfly plate rotating with the valve stem as the opening and closing property to realize the opening and closing action. It is mainly used as a block valve. It can also be designed to have the function of regulation or section valve and regulation. Butterfly valve is more and more used in low-pressure large and medium-sized pipelines. Classification of pneumatic butterfly valve: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve and carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small volume, light weight and low cost. The characteristics of pneumatic butterfly valve are particularly remarkable. It is installed in a high-altitude concealed channel, controlled by two position five way solenoid valve, easy to operate and can also adjust the flow medium.
