Fig. 2 for Fig. 1 A-A to sectional view.
Wherein：1st, it is outer tube 2, filter screen 3, slideway 4, ttom of pipe stepper motor 5, enters grain passage 6, tube top stepping
Motor 7, sampling room 8, angular wheel 9, thief hatch 10, cable wire
The present invention is further described below by embodiment
(1) rotating shaft sampling apparatus
Rotating shaft sampling apparatus is to realize the first step for measuring silo inside grain sampling.In the present invention, rotating shaft sampling cartridge
Put the thief hatch in the middle of ttom of pipe stepper motor and body, filter screen and enter grain passage etc. and constitute.
Stepper motor is a device for electric pulse being converted into discrete mechanical movement, is controlled with good data special
Property, and it can open ring position control, one pulse signal of input just obtains a defined positional increment, such so-called to increase
Position control system is measured compared with traditional DC control system, its cost substantially lowers, and must hardly carry out system call interception.Cause
The power set rotated in this present invention using stepper motor as tube wall, allow outer tube wall to accomplish that open loop rotates control.
Rotating shaft sampling arrangement samples process is as follows：
Ttom of pipe stepper motor drives outer tube wall to rotate by gear and slideway, because the filter screen on outer tube wall is sampled with stretching out
Mouthful the grain passage that enters be in same level position, therefore when filter screen skims over thief hatch part by rotating, the grain of grain heap can be
Filter screen is pressed into the presence of pressure, is entered via grain passage is entered among sampling room.To avoid disposably entering excessive grain
Sample, can be adjusted by the selection to filter screen and the number of times for changing the ttom of pipe stepper motor speed rotated and skimming over.
Rotating shaft stepper motor, thief hatch and screen location are as shown in Figure 1.
(2) sampling and measuring device
Multiple sensors of the sampling and measuring device in sampling room 7, tube top stepper motor 6 and sampling room are constituted, responsible pair
The ambient parameter of sample carries out detection and sample takes out.
Measurement sensor has 18b20 accurate temperature sensors, DHT11 Temperature Humidity Sensors and MQ4 (gas), a MQ7 (oxygen
Change carbon CO) gas sensor.After there are DHT11 Temperature Humidity Sensors, 18b20 temperature sensors are added again to temperature
It is because DHT11 temperature detection range highest only reaches 50 DEG C, and response is not rapid enough, works as silo to carry out independent measurement
During the interior generation emergent accident such as fire, it is desirable to be able to which rapid reaction and operating temperature higher 18b20 relatively enters to temperature
Row detection, have more rapid reaction to fire to reach, can and alarm, improve the guard sensitivity of system.
After grain sample enters sampling room, the ambient parameter measured from sample is transferred to core by multiple sensors
Controller, while pulling sampling room 7 to rise by tube top stepper motor 6, sample is taken out.

In reduction ambient humidity and temperature；
Stepping of the present invention can be detected to grain internal environment parameter, additionally it is possible to accomplish slight management and control.Environmental Kuznets Curves
Device is made up of axial flow blower.
It is well known that the environment of grain storage is preferred with low temperature drying, the present invention is dropped simultaneously by the effect of axial flow blower
Low ambient temperature and humidity.Accomplish the slight management and control to ambient temperature and humidity.
(4) core controller
The core control system is located at outer tube body inside top, ZigBee wireless-transmission networks and display and warning device
By core controller.
Core controller is mainly passed by the control and the use of multiple sensors to each executing agency and to ZigBee
The application of defeated network completing to sample, sample, measure and the function such as information transfer.Core controller is with Freescale company
MK60DN512ZVLQ10 single-chip microcomputers are processor, coordinate other ancillary equipment basic circuits and electrical apparatus driving circuit module to it
He is controlled device.
