Description

Multistage connection mode probe
Technical field
The present invention relates to a kind of multistage connection mode probe, the multistage connection mode probe of especially a kind of grain depot information data collection and management system and grain moisture content detector.
Background technology
Grain security is the important foundation realizing Economic development, social stability and national security. In November, 2015, the General Office of the State Council printed and distributed " State Council is about the some suggestions establishing and improve grain security governor's responsibility system " and " grain security governor's responsibility system evaluation method ", indicated country to the great attention of grain security. The important task in one period at present and in the future is exactly set up and gradual perfection examination mechanism, and the main body responsibility of comprehensive reinforcement this area grain-production, deposit and circulating capacity construction that (district, the city) People's Government of each province is undertaken is fulfilled. This wherein implements local grain reserves, strengthens grain storage ability, and supervision manages, it is ensured that local stored grain quantity is true, quality safety guarantees an important behave of grain security.
In grain storage process, owing to the cycle (about 3 years) of grain storage is long, grain storage number ratio relatively big (the storage amount of a usual grain depot reaches several hundred tons of even thousands of tons ofs), adding the change of different areas seasons, weather, temperature and humidity, annual country is because grain moisture regain, the grain storage loss caused of going mouldy are very big. In fact, a lot of grain depot is annual because the grain stored produces moisture regain and the go mouldy loss caused and financial loss up to hundreds thousand of unit, bring serious loss to national wealth. How effectively to reduce and avoid because grain gets damp again, each country's grain depot and local grain depot are challenges by the grain storage loss caused of going mouldy.
By in grain depot to the monitoring of the moisture content of the grain stored, temperature and humidity, effective means and testing apparatus is used to carry out frequent, successive monitoring and obtain these data, analyze these data, and take adequate measures (turn over shine or dry) to prevent the grain stored from moisture regain not occurring and goes mouldy when being necessary in time, it is the measure that grain depot administrative authority can take to ensure that the quality of the grain stored during storing does not change. And in grain depot, the monitoring of the moisture content of the grain stored is especially important, when the water content of the grain stored is in one is reasonably interval, it is possible to think that the quality of stored grain is stable. Otherwise, beyond this rational interval can think these grains will occur moisture regain and go mouldy, so by the monitoring of the moisture content of grain for manager's decision-making when take adequate measures provide important evidence.
Grain heap in grain depot is not only high but also big, its diameter or length, width and height size are often greater than 10 meters, and it is positioned at the grain of Liang Dui center and bottom section, due to its grain of the grain heap surface being not so good as in grain depot with permeability that ventilates, thus, more easily there is moisture regain and goes mouldy in the grain being positioned at Liang Dui center and bottom section.

There are now use temperature logging and wet bulb thermometer that the temperature in grain depot and humidity are carried out tracking and testing, indirectly judge that the possibility of moisture regain occurs in grain according to the change of temperature and humidity. And temperature polling instrument uses wired multi-channel approach to carry out Signal transmissions, circuit is easily damaged, easily disturbed, and sensor infringement is not easily replaced. The quantity of information that logging panel provides is not easy to be recorded storage less and prints.
The grain moisture content detector having now use general enters storehouse at grain and delivers from godown is gathered by grain moisture content and test. But, now general moisture detector, due to probe short (< 50cm) so the grain moisture content of grain heap surface can only be tested, can not test grain heap bottom center region grain moisture content, have very big testing blind zone. It is big by artificial timing detection workload in addition, trackability is poor, and the result of test is limited to the sense of responsibility of staff sometimes.
