Intelligent ventilating system of barn and control method thereof

Abstract

The invention discloses an intelligent ventilating system of a barn. The intelligent ventilating system comprises a master-control computer (1) and is characterized in that the master-control computer (1) is connected with a master-control unit wireless module (2), the master-control machine wireless module (2) is connected with an auxiliary unit wireless module (3) through wireless signals, the auxiliary unit wireless module (3) is connected with a detection auxiliary unit (4) which is connected with a passive switch module (6), and the passive switch module (6) is connected with a driving auxiliary unit (5). By means of effective matching of links in a circuit, the intelligent ventilating system enables the barn to be always in a dry and ventilating state and is favorable for storing of grains. The intelligent ventilating system and a control method of the system are experimented in central standing grain Zhengzhou subordinate storehouse and are proved to be favorable for storing of grains according to the experimental results, and quality of the grains is ensured not to descend.

Description

technical field [0001] The invention relates to a granary ventilation system, in particular to an intelligent granary ventilation system and a control method thereof. Background technique [0002] my country is a big country of grain production. In 2006, my country's total grain output reached 994.9 billion catties, and the per capita share was more than 700 catties. In 2007, it has exceeded the 1 trillion mark. According to statistics, the average annual loss of grain in my country due to disasters, rats, pests and fungi is about 100 billion catties, which is equivalent to 1 / 10 of the annual output. Someone once made such an analogy that the combined mouths of 1.3 billion people are larger than Tiananmen Square, the largest square in the world. What a mouth! Just the 15 million new people added each year will eat 5 billion kilograms of grain! Therefore, food security is of great significance to our country. The quality and safety of stored grain is related to the devel...

Problems solved by technology

In recent years, with the increase of the country's investment in the construction of grain depots, the conditions of grain storage have been significantly improved. Coupled with the application of some new technologies, rodents and pests in the grain depots have been effectively controlled, but the problem of preventing grain mold A lot of human, material and financial resources are invested every year

After long-term exploration and practice, it has been proved that as long as the temperature and humidity in the granary are effectively controlled, the grain in the granary can be well preserved, and the methods of effectively controlling the temperature and humidity in the granary include natural ventilation, strong exhaust and strong blast etc., and these methods are currently realized through artificial methods. The artificial ventilation method will cause many disadvantages such as untimely ventilation. If the ventilation is not timely, it will cause a large amount of food to go moldy and deteriorate.
