It should be noted that the predetermined altitude can determine according to actual needs, which is used to identify grain
Whether the stock amount in storehouse there is unreasonable variation suddenly.
Assuming that the h that receives of upper second processor 103 is h1, this h received is h2, Δ h=h2-h1 be this highly with it is upper
The difference of secondary height, predetermined altitude T.
When the height h2 is sent to the processor 103 by the distance measuring sensor, the processor 103 will be according to public affairs
Formula Δ h=h2-h1 calculates this difference highly with last time height.Indicate that the stock amount of silo increases if Δ h > 0, if Δ
H < 0 item indicates that the stock amount of silo reduces.If the absolute value of difference | Δ h | > T, then it represents that the stock amount of silo occurs
Unreasonable variation.For example, distance measuring sensor is blocked by barrier, then the height h that distance measuring sensor obtains can become suddenly

M1 is the difference of the quality of this quality and last time acquisition that obtain.
The height h is sent to the processor 103 by the distance measuring sensor, and the processor 103 is according to the height
It spends h, tested region bottom surface coordinate and grain density and obtains quality m2, the processor 103 will be obtained according to formula Δ m=m2-m1
The difference for the quality that the quality obtained to this and last time obtain, if Δ m ≠ 0, then it represents that the stock amount of silo changes,
Then this quality m2 obtained need to be sent to the server 105 by the processor 103；If Δ m=0, then it represents that silo
There is no variations for stock amount, then the processor 103 does not need the quality m2 that this is obtained being sent to the server
105。
The h and last time that the processor 103 of silo stock amount detection terminal provided in this embodiment is used to receive this are received
To h be compared, when the two difference be more than predetermined altitude, then alarm.It is thus possible to timely remind silo work
There is improper situation in silo, observe conditions in time to silo convenient for staff, by the damage of grain in silo in personnel
Mistake is reduced to minimum.The processor 103 is also used for receiving the error code that the distance measuring sensor is sent, according to the error code
The fault type for judging the distance measuring sensor then will be upper when judging fault type for the distance measuring sensor itself exception
The quality of secondary calculating is sent to the server.Since the data of fault sensor measurement are insincere, and between the measurement of sensor
Every short, thus adjacent result difference twice is smaller, thus, it is accurate to ensure that the detection terminal carries out the stock amount of silo
Detection in real time.The processor 103 is also used to periodically judge whether the quality changes, when quality changes
When, then the quality after variation is issued into the server, on the contrary it does not send.To save processor 103 and server 105
Between communication space, increase data transmission efficiency, be easy to implement the terminal real-time detection silo stock amount.

Stating laser sensor and the sonic sensor is cross-distribution.The reason of using the distribution, is as follows:
Laser sensor anti-interference ability is stronger, will not generate interference from each other, but laser sensor can only be surveyed
The distance of amount between points, so laser sensor coverage area is smaller.If all distance measuring sensors all select laser
Sensor needs to increase the quantity of distance measuring sensor to reach default accuracy, will increase the cost of detection silo stock amount.
However, sonic sensor can be with the distance of measurement point to face, coverage area is larger, but sonic sensor is anti-interference
Ability is weaker, and sound wave can be interfering with each other between different sonic sensors.If all distance measuring sensors all select sonic sensor,
Due to the interference between different sonic sensors, reduce measurement accuracy.In order to avoid different sonic sensors generate interference, sound
Wave sensor cannot be mounted on adjacent position, need to be spaced a certain number of laser sensors；In order to make full use of resource, sound
Wave sensor should not be distributed in boundary position；, can be adjacent however, the installation site of laser sensor does not require, it can also be with
