Description
Technical field:
The present invention 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.
Summary of the invention:
The objective of the invention is provides the intelligent ventilation system of grain depot that a kind of working strength is low, efficient is high, automaticity is high, reliability is high in order to overcome above deficiency.
Purpose of the present invention is achieved through the following technical solutions: a kind of intelligent ventilation system of grain depot, comprise ventilation transom window mechanism, control gear and testing agency, between described general mood window mechanism and the described control gear, all connect between described control gear and the described testing agency by electric wire, ventilation transom window mechanism comprises the vent window fixed window frame, the bottom interior surface of vent window fixed window frame and both sides inside surface are hinged with vent window motion forms, vent window motion forms are made up of two sections vertical parts and one section horizontal component, horizontal component is located between the branch of described two sections vertical portions, the end of two sections vertical components of vent window motion forms all is hinged with vertically disposed drive link by pull bar, every drive link all is welded in the driving rotating shaft of same horizontal positioned, one end of described driving rotating shaft is provided with the clutch shaft bearing bearing, the other end that drives rotating shaft is connected with worm-and-wheel gear, be provided with second bearing spider near the end in the driving rotating shaft of worm-and-wheel gear, the vertical direction of worm-and-wheel gear is connected with drive motor, drive motor links to each other with control gear, one end of the horizontal direction of worm-and-wheel gear is connected with position detecting device, bearing spider, worm-and-wheel gear and position detecting device all are located on the installation base plate of horizontal positioned, be provided with the PLC control system in the control gear, the outside surface of control gear is provided with touch-screen.
Further improvement of the present invention is: the humiture monitoring modular in the testing agency detects airborne humiture, and change into signal it is sent in the PLC control system of described control gear, described PLC control system carries out passing the signal on the touch-screen on described control gear surface after the signal Processing, screen displaying information, produce new signal and pass to the PLC control system again or pass to receiver module in the described control gear by the contact touch-screen by the signal that wireless remote control module sends, receiver module is passed to the PLC control system with signal, the PLC control system is carried out signal Processing, at last signal is passed to the motor in the described ventilation transom window mechanism.
The present invention compared with prior art has following having a few: the present invention is based on the automatic control that sensing detection technology, wireless remote control technology, human machine interface technologies and intelligent control technology etc. realize that grain depots ventilate, have that working strength is low, efficient is high, automaticity is high, the reliability advantages of higher, for grain storage provides a kind of high performance ventilating system, have and use widely and promotional value.
