Abstract
The utility model relates to a wireless WIFI regulating and controlling system based on pyroelectric temperature sensor detection. The system comprises a grain bin. The bottom part of the grain bin is provided with multiple air pipes. The side walls of the air pipes are respectively provided with multiple branch pipes to the internal part of the grain bin. The air pipes are respectively connected with an air blower. The internal part of the grain bin is provided with multilayer installing plates which are vertically arranged. The lower surfaces of the installing plates are fixedly connected with multiple pyroelectric sensors. The pyroelectric sensors arranged on any one of the installing plates are grouped and then connected with a control unit. The control unit is connected with a local host via a WIFI transmission unit. The WIFI transmission unit comprises an RF generator and an RF receiver. The local host controls the air blower via the control unit. Temperature change of grain is monitored via thermistors, and temperature change of grain in the grain bin is remotely monitored by the local host via the WIFI transmission unit so that distance limitation of original cable transmission is avoided, and thus the system has characteristics of being convenient to operate and reliable in control.
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.Particularly large-scale state-owned silo, 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 ensures grain is exactly mainly to ensure 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, ventilate, dry and the work such as cooling not meeting the storehouse of temperature and humidity requirement, 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 wireless WIFI regulator control system detecting based on pyroelectricity temperature sensor is provided, and it has controls simply, detects reliable feature.
The technical scheme that the utility model adopts is as follows:
The wireless WIFI regulator control system detecting based on pyroelectricity temperature sensor, comprises silo, many airducts of bottom device of silo, and the sidewall of airduct is respectively equipped with multiple 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 multiple pyroelectric sensors; Pyroelectric sensor on arbitrary installing plate is connected with control module after being group, and control module is connected with local main frame by WIFI transmission unit, and WIFI transmission unit comprises RF generator and RF receiver; Local main frame is by control module control blower fan.
The beneficial effects of the utility model are as follows:
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 WIFI 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 multiple 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 multiple 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 WIFI transmission unit 8, and 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, in the time that temperature raises, the electric charge that pyroelectric sensor 5 discharges can be exchanged into Voltage-output through amplifier, in the time that Voltage-output exceedes the threshold voltage of setting, signal is passed to control module 6 by it, control module 6 is transmitted to local main frame 7 by signal by WIFI transmission unit 8 is long-range, 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 WIFI transmission unit 8 to be started blower fan 3 and works, cold wind is through airduct 2 and be in charge of 21 and enter silo 1 and realize the cooling to 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; Realize cereal temperature in local main frame remote monitoring silo by WIFI transmission unit and change, avoided the distance limit of original cable transmission, have easy to operately, control reliable feature.
