Abstract
The utility model relates to a high-efficiency insect preventing and killing automatic monitoring device, which is provided with a central automatic control system device, a barn detection device of a reserve base and a central processor, wherein, one end of a signal terminal of the central automatic control system device is connected with a PH [3] automatic reactor, a critical flow venturi and a sucking pump, and the PH [3] automatic reactor and the signal terminal of the sucking pump are connected with the signal output end of the central processor in a forward direction relative to the critical flow venturi. The signal terminal of the critical flow venturi is connected with the signal input end of the central processor in an inverse direction relative to the PH [3] automatic reactor and the sucking pump.
Description
The utility model relates to a kind of to reserve storage, particularly to the deposit online detection of silo concentration of fumigant and distribution carrying out and to fumigant takes place and transportation and distrubution apparatus is controlled in real time device.
The general phosphine (PH that uses of reserve storage fumigation technology with certain proportioning
3) and CO
2Combination gas be fumigant through field control, effectively discharge, reach the defending insect and killing purpose.
Original on-the-spot generation technology is directly to throw in aluminum phosphide tablet in the warehouse, and it checks the infested rate control of grain by impressions, injected volume and artificial spot sampling.The subject matter that this method exists is: the warehouse insect pest situation is difficult to carry out online detection and control in real time; Simultaneously, can't control each position concentration of fumigant of warehouse equably, cause regional area concentration higher and have some zones to become the phenomenon of " blind area ", not reach best insect protected, insecticidal effect.
In order to address these problems, existing way is to adopt PH on the basis of re circulation fumigation
3/ CO
2Steel cylinder combination gas venting technology.The employing of this technology has solved the irregular phenomenon of tablet dispensing concentration.But it also is difficult to solve implements online detection and the problem of controlling in real time to the warehouse insect pest situation.
The purpose of this utility model provides a kind of efficient insect protected automatic monitored control system, it can be to reserve storage, particularly take place and transportation and distrubution apparatus is controlled in real time, reach appropriateness, effective effect to the deposit online detection of silo concentration of fumigant and distribution carrying out and to fumigant.
The purpose of this utility model is achieved in that the PH of employing based on electrochemical principle
3Concentration sensor is controlled fumigant generation and transportation and distrubution apparatus by the central controlled processing unit that possesses A/D and D/A translation function as sensitive element.
The utility model can reach the defending insect and killing effect safely, efficiently, easily owing to adopted online detection and the mode of controlling in real time; The total system information transmission is a closed loop configuration, has got rid of the influence of artificial subjective factor; Owing to adopted PH
3Electrochemical sensor can carry out Quantitative Monitoring to the warehouse concentration of fumigant; Setting up of central control room can be reacted the stifling dosage in full Ku Geku storehouse comprehensive, round-the-clockly, for the accurate dispensing of fumigant provides reliable basis.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the flowage structure figure according to the high-efficiency prevention and control desinsection automatic monitored control system that the utility model proposes.
Fig. 2 is the fundamental diagram of the prior art that adopts of the utility model central processing unit, warehouse storehouse pick-up unit and the central automaton that constitute.
Below in conjunction with detail and the working condition of accompanying drawing detailed description according to the device that the utility model proposes.
This device comprises CPU (central processing unit) 1, warehouse storehouse detection system 2, central automatic control system 3, PH
3Automatic reactor 4, critical flow Venturi 5 and aspiration pump 6.A/D and D/A conversion hardware and Control Software are wherein arranged in the main body of central processing unit 1, three PH that are designated A, B, C are respectively arranged in the main body of warehouse storehouse pick-up unit 2
3Sensor, the demonstration of main body inner information, feedback and the autoalarm of central automaton 3,5 main body has 2 temperature and pressure transducer respectively.
As storehouse, storehouse PH
3Concentration is lower than under the safe concentration of defending insect and killing in limited time, central automatic control system report to the police and feedback information to CPU (central processing unit), carry out data-switching by CPU (central processing unit), and then control PH
3The action of automatic reactor, critical flow Venturi and aspiration pump reaches the dispenser purpose.In this process, PH
3Sensor is with PH in the storehouse, storehouse
3Instantaneous concentration feeds back to CPU (central processing unit) with electrical signal form by online mode, and carries out data-switching by CPU (central processing unit).As storehouse, storehouse PH
3Concentration reaches on the safe concentration of defending insect and killing in limited time, sends instruction by CPU (central processing unit), stops PH
3The action of automatic reactor, critical flow Venturi and aspiration pump, dispenser finishes.
