Embodiment 1

[0035] like figure 1 The illustrated embodiment is a method for monitoring grain storage in a granary. The monitoring method is suitable for a grain storage monitoring device. The monitoring device 8 is located on the top of the granary, and the monitoring device is connected to the computer 1; The device comprises a motor 2 located on the top of the granary, an alarm 7 and a two-dimensional turntable 3 connected with the motor; the rotating shaft of the motor is connected with the two-dimensional turntable; the bottom of the two-dimensional turntable is provided with a distance sensor 4; The two-dimensional turntable includes a left and right rotation axis 5 and a front and rear rotation axis 6; the rotation angle of the left and right rotation axes is -58° to 58°. The lower part of the two-dimensional turntable is provided with a dust cover for covering the ranging sensor.

[0036] The rotation angle of the left and right rotation axis is -58° to 58°. The rotation angle of...

Embodiment 2

[0050] Embodiment 2 includes all structures and steps in Embodiment 1, and also includes the following steps:

[0051] Every 8 hours, carry out a monitoring scan on the upper surface of the grain in the granary, repeat the steps 100 to 300 to calculate the grain quality variation between adjacent monitoring scanning times, if there is no artificial grain change between adjacent monitoring scanning times operation and the grain quality change rate exceeds 0.5%, the alarm will alarm.

[0052] For example: a monitoring scan was carried out at 2:00 on January 3, and the grain storage quality was 120,000 kg; a monitoring scan was carried out at 10:00 on January 3, and the grain storage quality was 119,200 kg; The rate of change is 0.67%; and there is no manual food intake and output operation between 2:00 on January 3 and 10:00 on January 3, the controller will control the alarm to alarm. It shows that there are abnormal situations such as grain rot, rat infestation or insects in ...

Abstract

The invention discloses a monitoring method for grain stock in a barn. The monitoring method can be used for scanning the upper surface of grains in the barn when the barn is empty and after the grains are put in and got out of the barn; a three-dimensional coordinate point set of the surface of the grains stored in the barn at the moments when the barn is empty and after the grains are put in and got out of the barn is obtained respectively; a barn model corresponding to each moment is constructed by software in a computer according to the three-dimensional coordinate point set at each moment respectively; and the size of the barn model is calculated, the grain stock size after ith grain inlet or outlet is calculated, the grain stock after ith grain inlet or outlet is calculated according to the density of the grains and the grain storage size, and Mi is stored in the computer. The monitoring method has the characteristics of capabilities of monitoring the grain stock and the grain variation during each gain inlet and outlet in real time, timely discovering the abnormal condition of the grains in the barn and reducing the loss to the minimum, high measuring precision, simple, convenient and quick monitoring process and capability of reducing the manual cost.

Description

technical field [0001] The invention relates to the technical field of granary management, in particular to a monitoring method for grain storage in a granary that can detect grain storage and each grain variation in real time and has high measurement accuracy. Background technique [0002] At present, in the daily management of the granary, the grain storage in the granary is mainly obtained through two methods: [0003] One method is the ruler measurement method: the volume of the grain in the granary is obtained by measuring the ruler, and then the grain storage capacity is calculated according to the density of the grain and the measured volume value. This method has the disadvantages of complex and cumbersome measurement process and poor measurement accuracy. [0004] Another method is the weighing measurement method: measure and record the amount of grain changes in each granary, and calculate the grain storage volume in the granary by querying the grain change record...
