Agricultural Meteorological Detector: "Shunfeng Ear" and "Clairvoyance" for Meteorological Monitoring
In recent years, China's grain output has continued to be high, and behind it, it cannot be ignored that meteorological monitoring provides an important guarantee for fertilization. We all know that the growth of crops has strict requirements for the climate environment. Insufficient light, too much or too little rainfall, too high or too low temperature will affect the germination of seeds and the growth of crops, but to ensure the healthy growth of crops, It requires people to obtain the changes of various climate parameters in real time, and take effective measures to intervene in time. Among them, various types of agricultural meteorological detectors serve as the "shunfeng ear" and "clever eye" in meteorological monitoring.
Meteorological monitoring and forecasting is the traditional meteorological management method in agriculture. With the continuous improvement of agricultural refinement, professional agricultural microclimate monitoring becomes more and more important. Therefore, it is necessary to use small but comprehensive agricultural meteorological detectors. Meet the needs of small environmental monitoring. The agricultural meteorological detector can monitor and record the air temperature, humidity, precipitation, sunshine, radiation and other climatic conditions in the planting site, guide agricultural production, and promote the increase of agricultural yield. The promotion and application of agrometeorological detectors in agricultural parks, demonstration bases, family farms, etc. are of great significance for ensuring the safety of production and promoting the high-quality and efficient development of modern agriculture.
Reducing the impact of adverse weather on agricultural production and using climatic and environmental parameters to guide crop production is actually improving quality and increasing production. From this perspective, at present, the demand for agricultural meteorological detectors is increasing. The application of such meteorological instruments It will help to further improve the deficiencies of grassroots meteorological monitoring services, strengthen meteorological service capabilities, meet the actual needs of refined meteorological services and modern agriculture, improve crop growth environment, and highlight the social, economic and ecological benefits of meteorological services.
Slewing Controller is a kind of Tower Crane slewing control device, combined speed and voltage regulation and eddy current speed controling. The slewing control block control the speed of eddy current torque motor, to make the tower crane slewing mechanism start, working and stop smoothly. This kind of Slewing Controller is used to regulate and control the speed of three-phase torque motor of AC 50Hz, voltage 380V.
HRCV slewing controller is a hoisting slewing controller developed by our company according to service condition of customer.
The main technical feature as follows:
(1) This product combined the controller and thyristor module,the connection of the users is simple and easy.Prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
