Description
Technical field
The present invention relates to a kind of multi signal multistage interconnection system probe, especially a kind of grain depot information data collection and pipe
The multi signal multistage interconnection system probe of reason system and moisture detector for cereal.
Background technology
Grain security is to realize the important foundation of economic development, social stability and national security.In November, 2015 State Council
General office prints and distributes《Some opinions of the State Council on establishing and improve grain security governor's responsibility system》With《Grain security governor blames
Appoint evaluation method processed》, indicate great attention of the country to grain security.As soon as the vital task in a period at present and in the future,
It is to establish simultaneously gradual perfection appraisal mechanism, comprehensive reinforcement this area grain-production, the storage that (the area, city) People's Government of each province is undertaken
Standby and negotiability construction main body responsibility is fulfilled.Local grain reserves are implemented among these, are strengthened grain storage ability, are added
Strong supervision and management, it is ensured that local stored grain quantity is true, quality safety is to ensure that an important measure of grain security.
During grain storage, since the cycle (3 years or so) of grain storage is long, the quantity ratio of grain storage
Larger (the storage amount of a usual grain depot up to hundreds of tons even thousands of tons of), plus different regions season, weather, temperature and humidity
Change, annual country because grain moisture regain, go mouldy caused by grain storage loss be very big.In fact, many grain depots
Annual caused loss and economic loss because the grain generation stored gets damp again and goes mouldy are up to hundreds thousand of members, to national wealth
Bring serious loss.How to efficiently reduce and avoid because grain moisture regain, caused grain storage loss of going mouldy are to each
A country's grain depot and local grain depot are all a challenges.
By to the monitoring in grain depot to the moisture content, temperature and humidity of the grain that are stored, using effective means
Come often with test equipment, continuously monitor and obtain these data, analyze these data, and it is timely when necessary
Adequate measures (ted or dry) are taken to prevent stored grain from not getting damp again and going mouldy, to ensure stored grain
It is measure that grain depot administrative department can take to eat quality during storage and do not change.And to institute in grain depot
The monitoring of the moisture content of the grain of storage is even more important, when storage grain water content in a rational section when, can
To think, the quality of storage grain is stable.Otherwise, it can consider that these grains will beyond this rational section
Appearance gets damp again and goes mouldy, so when taking adequate measures to provide weight for manager's decision-making by the monitoring of the moisture content to grain
Will foundation.
Grain heap in grain depot is not only high but also big, its diameter or length, width and height size is located at grain heap center commonly greater than 10 meters
With the grain of bottom section, the grain for the grain heap surface being not so good as due to its ventilation and permeability in grain depot, thus, positioned at grain heap
The grain of center and bottom section is easier appearance and gets damp again and go mouldy.And the grain of grain heap center and bottom section occur moisture regain and
After going mouldy, and soon its periphery and neighbouring grain can be had an impact, cause larger range of grain occur moisture regain and
Go mouldy.In addition, the grain positioned at grain heap center and bottom section is not readily observed, also it is not easy to be sampled, so being located at
The grain in this region is also not easy to be known after occurring getting damp again and going mouldy.Therefore, implement to area of silo grain heap bottom centre
The collection and test of domain grain moisture content are just extremely important.
Tracking and testing is carried out to the temperature and humidity in grain depot now with temperature in use logging and hygrometer, according to temperature
Change with humidity judges that the possibility to get damp again occurs in grain indirectly.And temperature polling instrument carries out signal using wired multi-channel approach
Transmission, circuit are easily damaged, easily disturbed, and sensor infringement is not easy to be replaced.The information content that logging panel provides is few not
Easily it is recorded storage printing.
Now with using general grain moisture content detector grain warehouse entry and export be grain moisture content is acquired and
Test.But moisture detector generally used now, due to probe it is short (<50cm) so the grain water of grain heap surface can only be tested
Part, it is impossible to grain heap bottom center region grain moisture content is tested, there is very big testing blind zone.In addition it detects work by manually timing
Work amount is big, trackability is poor, and the result of test is limited to the sense of responsibility of staff sometimes.The data of test are separated, scattered, no
Easily it is gathered and carries out unified analyzing and processing and filing.
It can be seen from the above that above-mentioned existing temperature polling instrument and grain moisture content detector have still suffered from the defects of many, and assistant officer
Wait to be improved.
