Description

Digitized grain depot intelligence inflated with nitrogen regulator control system
Technical field
The present invention relates to grain storage technical field, be specifically related to a kind of digitized grain depot intelligence nitrogen charging controlled atmosphere Ore-controlling Role.
Background technology
The level of IT application of China's Grain Trade and grain system ratio always is relatively low, especially informatization Develop unbalanced, and the grain system readjustment and reform of recent years so that original information monitoring basis Facility has been not suitable with new situation, information gathering dispersion, multiple facility and deposit, interface and exchange is independent, Standard disunity, information island phenomenon are serious." numeral grain depot " engineering, is that State Grain Administration is " ten Two or five " period implements under the background of " numeral grain " engineering, and emphasis realizes with management with the operation of grain depot Informationization, automatization and intelligence turn to construction object, by numeral grain depot management platform and numeral grain depot system System, it is achieved to stored grain centralized supervisory, strengthens government's specialty work to macro adjustments and controls of the grain ability, is The important component part of " numeral grain " engineering.The at present grain storage management work in grain depot exist with Lower problem:
1) grain depot information gathering means fall behind, and data message degree is the highest: existing system is to temperature, wet The data sampling acquisition means disparate development such as degree, insect pest, gas, moisture, in addition to temperature, humidity, The collection overwhelming majority of other data still uses artificial means to carry out collection in worksite.Meanwhile, management personnel Data are checked and often rests on paper form or operation system electric power list, it is impossible to current grain depot Information gets information about, and does not sets up the concept of visualization.Problem is that data base can revise, for Unreal data retention leak, lacks effective supervision.
2) grain depot management equipment needs Artificial Control, and it is the highest that data perception gathers automaticity: the most not The management means of few grain depot controls all to use manual operation also in labor power times, data acquisition and system, 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., have one so causing in the regulation of grain depot data Fixed hysteresis quality, it is impossible to be controlled timely, tends to the grain causing regulation management to cause not in time Food loss.
3) each control system of grain depot is relatively independent, lacks unified joint-action mechanism: at present involved by grain depot management To control system or equipment be all relatively independent, 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 is single, and between each system, lack coordination, it is impossible to complete complicated regulation and control task.
4) grain depot equipment standard disunity, numeral grain depot construction is pushed slowly: gets involved numeral grain depot at present and builds If producer large number of, only product sensor supplier is just in the face of numerous rivals of the same trade, For protection its knowledge property right and the purpose of trade secret, producer formulates the interface standard of product the most voluntarily And communication protocol, and numeral grain depot construction is a numerous and jumbled System Integration Engineering, different piece relates to factory Family is numerous, and skimble-scamble technical standard specification brings obstruction greatly during the system integration, delays Grain depot digitized upgrading progress.
Nitrogen filling grain storage technology is one of the most state-of-the-art current grain storage new technique, is to substitute chemistry The second filial generation grain storage new technique of medicament routine grain storage.Exploitation application Green Grain Storage technology is the outer grain of Now Domestic The main development direction of food storage technology, this technology is possible not only to reduce grain storage chemical agent to grain and ring The pollution in border, reduce the injury healthy to grain guarantorizations personnel, it is also possible to reduce resisting of grain storage pest The property of medicine, the storage quality of holding grain, be a revolution of View of Grain Storage Technoiogy.There is 21st century The modernization grain depot of important symbol is exactly must popularization and application green nitrogen charging air-conditioning storing grain technology.
Summary of the invention
