Description

Intelligent ventilation system of grain depot

Technical field:

The utility model relates to a kind of grain storage management system, is a kind of system that can realize the control of grain depot intelligent aeration automatically.

Background technology:

Grain reserves are being safeguarded grain market and social stability, protection peasant benefit, are being guaranteed to have born in the national security substantial responsibility as national important strategic goods and materials.The Chinese government grabs the grain reserves management always as an important economic work.Since 1998, state revenue drops into national debt fund in three batches continuously, has built state grain depot.Present stage China's grain reserves storage facilities condition is greatly improved, and stored grain are kept in the good warehouse of condition basically, and quantity, the quality of stored grain are progressively reliably guaranteed.At present grain storage directly under in the storehouse, the grain storage technical merit obviously improves, and has also carried out technological transformation on hardware, storage and affiliated facility are greatly improved.Grain stock check result showed in recent years, and the stored grain quality condition has reached better level, provided safer, high-quality, green grain source to market.Meanwhile, the cost direct relation state revenue and expenditure cost burden of stored grain will reduce handling cost in the grain storage process, guarantee preservation and increment of the value of state assets.Strengthen employee quality, strengthen the stored grain handling facility, improve the stored grain management level and the quality of storing up grain and then seem particularly important.

Worm, the harm of mould, mouse are the most serious in the grain storage process.Storage pest causes the heating of grain heap, even goes mouldy, even the embryo of the grain seed of damaging by worms, and can not normally germinate, and causes serious economy loss.Its loss also causes the reduction of loss of grain nutritive value and sanitary condition except grain quality, the influence mankind's is healthy.In order to improve foodstuff preservation stability, reduce mass loss, delay aging, make green relieved grain engineering, need to detect the indexs such as temperature, humidity of grain, and accomplish timely management, ventilating according to testing result and the outer weather of grain depot in real time is a kind of comparatively common management method.

At present, the sun-roof ventilating opening of the many employings of the ventilation of grain depot is opened manually and is realized ventilating.Though this mode can satisfy certain air-conditioning requirement, but there is more shortcoming, as: the accurate grain depot of a coordinate has nearly 20 ventilating openings, managerial personnel's labour intensity is big during opening and closing, length consuming time, be difficult to during abrupt change of climate react fast, realize that to the judgement dependence of outside weather is artificial reliability is low.At present traditional ventilating system mode has: (1) indoor opening type, wait the grain storage in warehouse full after, stepping on grain and opening vent window, bring the big shortcoming of intensity, must be simultaneously after the grain storage is full, just can realize; (2) outdoor opening type, for just solve the shortcoming that must can ventilate after the grain storage is full, from the external opening vent window, this mode managerial personnel's labour intensity is still very big by linkage assembly, present most of grain depots still adopt this mode; (3) electric drive-type, this mode mainly are to replace manually having reduced the intensity of manager works by motor, could realize operation but need managerial personnel to go to each vent window position, it is loaded down with trivial details to work, and efficient is low, has the part grain depot to adopt this mode to realize ventilating at present.
