Abstract
The invention relates to an intelligent wireless regulation and control system based on thermistor detection. The intelligent wireless regulation and control system based on thermistor detection comprises a granary, wherein a plurality of air pipes are installed at the bottom of the granary, a plurality of branch pipes which lead to the interior of the granary are arranged on the side wall of each air pipe, and the air pipes are connected with a fan; a plurality of monitoring rods which are evenly distributed are inserted into the granary, a plurality of thermistor sets which are vertically arranged are distributed on the monitoring rods, and each thermistor set comprises a plurality of thermistors which are distributed in the mode of being symmetric about the center axis of the corresponding monitoring rod; after the monitoring rods are combined into a monitoring rod set, the thermistor sets on the monitoring rod set are connected with a control unit in a grouping mode; the control unit is connected with a local host through a wireless transmission unit, the wireless transmission unit comprises an RF generator and an RF receiver, and the local host has control over the fan through the control unit. According to the intelligent wireless regulation and control system based on thermistor detection, monitoring of changes of the temperature of grains is achieved through the thermistors, the purpose that the local host carries out remote monitoring on the changes of the temperature of the grains in the granary is achieved through the wireless transmission unit, and the intelligent wireless regulation and control system based on thermistor detection has the advantages of being convenient to operate and reliable in control.
Description
Technical field
The present invention relates to silo, relate 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.Play and ensure that the safe storage of 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.
Summary of the invention
The above-mentioned shortcoming that the applicant exists for prior art, studies and improves, and a kind of intelligent wireless regulator control system detecting based on thermistor is provided, and it has controls simply, detects reliable feature.
The technical solution adopted in the present invention is as follows:
The intelligent wireless regulator control system detecting based on thermistor, comprises silo, it is characterized in that: 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 inside of silo is plugged with many equally distributed monitoring rods, is furnished with multiple thermistor groups setting up and down on monitoring rod, and thermistor group comprises multiple about the symmetrical thermistor of the central shaft of monitoring rod; Many monitoring rods are after group thermistor group on it and are group and are connected with control module, and 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 by control module control blower fan.
Beneficial effect of the present invention is as follows:
The present invention by the thermistor on monitoring rod along with the variation of the temperature of grain in silo changes, thereby the electric current in control module also changes thereupon, in the time that 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 signal RF receiver that is transmitted to, signal is passed to local main frame by RF receiver, 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 by wireless transmission unit and start blower fan work, cold wind is through airduct and be in charge of and enter silo and realize the cooling to grain, prevent that it from rotting.
The present invention realizes the temperature variation of monitoring grain by thermistor, and realizes cereal temperature in local main frame remote monitoring silo by wireless transmission unit and change, and has avoided the distance limit of original cable transmission, has easy to operately, controls reliable feature.

Fig. 2 is front view of the present invention.
Fig. 3 is duty block diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1, Fig. 2 and Fig. 3, the present invention includes 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 inside of silo 1 is plugged with many equally distributed monitoring rods 4, is furnished with multiple thermistor groups 5 setting up and down on monitoring rod 4, and thermistor group 5 comprises multiple about the symmetrical thermistor 51 of the central shaft of monitoring rod 4; Many monitoring rods 4 are after group thermistor group 5 on it and are group and are connected with control module 6, 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.
When the present invention works, thermistor 51 on monitoring rod 4 changes along with the variation of the temperature of silo 1 interior grain, thereby the electric current in control module 6 also changes thereupon, in the time that the value of electric current is greater than the threshold values of setting, control module 6 by signal the RF transmitter 81 by wireless transmission unit 8 by the long-range signal RF receiver 82 that is transmitted to, signal is passed to local main frame 7 by RF receiver 82, 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 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 monitoring rod 4.
The present invention realizes the temperature variation of monitoring grain by thermistor, and realizes cereal temperature in local main frame remote monitoring silo by wireless transmission unit and change, and has avoided the distance limit of original cable transmission, has easy to operately, controls reliable feature.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of amendment.
