Description
Technical field
The present invention relates to grain storage technical field, be specifically related to a kind of digitized grain depot intelligent temperature control system, specifically used in modern communication networks, Intelligent data analysis and Intelligent Measurement being combined with easy grain depot supervision, improve grain depot supervision reliability and effect.
Background technology
The level of IT application of China's Grain Trade and grain system is always relatively low, especially informatization development is unbalanced, and the grain system readjustment and reform of recent years, make original information monitoring infrastructure be not suitable with new situation, information gathering dispersion, multiple facility and deposit, interface and exchange independence, standard disunity, information island phenomenon serious." numeral grain depot " engineering, it is that State Grain Administration implements under the background of " numeral grain " engineering in " 12 " period, emphasis realizes informationization, automatization and intelligence with the operation of grain depot with management and turns to construction object, by numeral grain depot management platform and numeral grain depot system, realize stored grain centralized supervisory, strengthen government's specialty work to macro adjustments and controls of the grain ability, be the important component part of " numeral grain " engineering.Grain storage management work in current grain depot there is problems in that
1) grain depot information gathering means fall behind, data message degree is not high: existing system is to data sampling acquisition means disparate development such as temperature, humidity, insect pest, gas, moisture, except temperature, humidity, the collection overwhelming majority of other data still adopts artificial means to carry out collection in worksite.Meanwhile, checking of data is often rested on paper form or operation system electric power list by management personnel, it is impossible to current grain depot information is got information about, and does not set up the concept of visualization.Problem is that data base can revise, and for unreal data retention leak, lacks effective supervision.
2) grain depot management equipment needs Artificial Control, it is not high that data perception gathers automaticity: the management means of many grain depots is also in labor power times at present, data acquisition and system control all to adopt manual operation, wherein large number quipments carries out execute-in-place with greater need for staff, such as go out warehouse-in, lorry puts in storage unloading and driving path management, ventilation installation, refrigeration plant etc., so cause grain depot data regulate on there is certain hysteresis quality, can not be controlled timely, tend to cause regulating the grain loss that management causes not in time.
3) respectively to control system relatively independent for grain depot, lack unified joint-action mechanism: control system involved by grain depot management or equipment are all relatively independent at present, the access of each sensor of front end is formed without unified interface standard and agreement, it is impossible to equipment is uniformly accessed into and standardized management.Most equipment or systemic-function are single, and lack coordination between each system, it is impossible to complete complicated regulation and control task.
4) grain depot equipment standard disunity, numeral grain depot construction is pushed slowly: the producer getting involved numeral grain depot construction at present is large number of, only product sensor supplier is just in the face of numerous rivals of the same trade, purpose for protection its knowledge property right and trade secret, producer formulates interface standard and the communication protocol of product all voluntarily, and numeral grain depot construction is a numerous and jumbled System Integration Engineering, it is numerous that different piece relates to producer, skimble-scamble technical standard specification brings great obstruction in system integration process, delay grain depot digitized upgrading progress.
Such as Chinese patent CN103324221A, disclose a kind of grain depot intelligent comprehensive and control system, point for measuring temperature is distributed more widely, positioning performance is stronger, and electronic devices and components detection grain temperature can be stopped, do not fear hydrogen phosphide burn into employing wireless communication configuration, can remotely monitor grain feelings, monitoring effect and safety are all relatively strong, and range of application is wider.But complex in its structural design, fibre optic temperature sensor cost is high, be easily damaged, and uses environmental suitability strong the complexity of grain depot, and the comparatively unification that seems on software system function.
Such as Chinese patent CN103235572A, disclose a kind of intelligent digital grain depot supervisory systems, linked by temperature-humidity monitoring module and Ventilation Control module, storage capacity monitoring modular, can realize ventilating, the startup of stifling operation controls, automatically calculated current storage capacity by system, be greatly improved storage capacity computational accuracy.Its not foot point be in that monitoring range is less, communication mode is single, and function is comprehensive not.
