Description
Technical field
The utility model relates to silo, relates in particular to the maintenance system of silo.
Background technology
Grain is the basis of human survival and development, and grain security is to be related to Chinese national economy development, the Vital Strategic Problems of overall importance that social harmony is stable, national security is supported oneself all the time.Large-scale state-owned silo particularly, the amount of its grain reservation is larger, and the grain depot of requirement can be more, so just there will be the problems such as grain depot distribution range is extensive, and communication distance is far away, and the difficulty of unified management also can increase thereupon.The safe storage that guarantees grain is exactly mainly to guarantee that it is under normal temperature and humidity.
Traditional method is by test equipment such as humidity table, hair hygrometer, humidity test paper and thermometers, by manually detecting, to meeting the storehouse of temperature and humidity requirement, do not ventilate, dry and the work such as cooling, this manual testing's method wastes time and energy, efficiency is low and the temperature and humidity error of test is large, randomness is large.
Utility model content
The above-mentioned shortcoming that the applicant exists for prior art, studies and improves, and a kind of less radio-frequency regulator control system detecting based on regional temperature is provided, and it has controls simply, detects reliable feature.
The technical scheme that the utility model adopts is as follows:
The less radio-frequency regulator control system detecting based on regional temperature, comprises silo, it is characterized in that: many airducts of bottom device of silo, and the sidewall of airduct is respectively equipped with a plurality of leading to being in charge of of silo inside, and airduct is connected with blower fan respectively; The interior arrangement of silo has multilayer installing plate setting up and down, and the lower surface of installing plate is connected with a plurality of pyroelectric sensors; Pyroelectric sensor on arbitrary installing plate is connected with control module after being group,, control module is connected with local main frame by wireless transmission unit, and wireless transmission unit comprises RF generator and RF receiver; Local main frame is controlled blower fan by control module.
The beneficial effects of the utility model are as follows:
By the thermistor on monitoring rod, the variation along with the temperature of grain in silo changes the utility model, thereby the electric current in control module also changes thereupon, when the value of electric current is greater than the threshold values of setting, control module by signal the RF transmitter by wireless transmission unit by the long-range RF receiver that is transmitted to of signal, RF receiver passes to local main frame by signal, in the demonstration screen display silo of local main frame, there is abnormal position, operating personnel handle local main frame, signal is passed to control module startup blower fan by wireless transmission unit works, cold wind passes through airduct and is in charge of and enters the cooling of silo realization to grain, prevent that it from rotting.
The utility model is realized the temperature variation of monitoring grain by thermistor, and the cereal temperature of realizing in local main frame remote monitoring silo by wireless transmission unit changes, avoid the distance limit of original cable transmission, had easy to operately, controlled reliable feature.

Fig. 2 is front view of the present utility model.
Fig. 3 is duty block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
See Fig. 1, Fig. 2 and Fig. 3, the utility model comprises silo 1, many airducts of bottom device 2 of silo 1, the sidewall of airduct 2 be respectively equipped with a plurality of lead to silo 1 inside be in charge of 21, airduct 2 is connected with blower fan 3 respectively; The interior arrangement of silo 1 has multilayer installing plate setting up and down 4, and the lower surface of installing plate 4 is connected with a plurality of pyroelectric sensors 5; Pyroelectric sensor 5 on arbitrary installing plate 4 is connected with control module 6 after being group, and control module 6 is connected with local main frame 7 by wireless transmission unit 8, and wireless transmission unit 8 comprises RF generator 81 and RF receiver 82; Local main frame 7 is controlled blower fan 3 by control module 6.
In the utility model, because single pyroelectric sensor 5 can detect wider region, its number being arranged in silo 1 can suitably reduce, thereby reduces costs, when temperature raises, the electric charge that pyroelectric sensor 5 discharges can be exchanged into Voltage-output through amplifier, when Voltage-output surpasses the threshold voltage of setting, it passes to control module 6 by signal, control module 6 by signal the RF transmitter 81 by wireless transmission unit 8 by the long-range RF receiver 82 that is transmitted to of signal, RF receiver 82 passes to local main frame 7 by signal, in the demonstration screen display silo 1 of local main frame 7, there is abnormal position, operating personnel handle local main frame 7, signal is passed to control module 6 by wireless transmission unit 8 and start blower fan 3 work, cold wind passes through airduct 2 and is in charge of 21 and enters the cooling that silo 1 is realized grain, prevent that it from rotting, wherein, control module 6 and local main frame 7 are set according to the grouping number of installing plate 4.
Pyroelectric sensor of the present utility model can detect wider region, has reduced cost; The cereal temperature of realizing in local main frame remote monitoring silo by wireless transmission unit changes, and has avoided the distance limit of original cable transmission, has easy to operately, controls reliable feature.
