Silo material inventory dynamic detection device and method

Abstract

The invention discloses a silo material inventory dynamic detection device, wherein the device comprises an X-axis stepping motor, a Y-axis stepping motor and a radar level meter; an output shaft of the X-axis stepping motor is connected with the radar level meter, and the Y-axis stepping motor is connected with the upper end of the X-axis stepping motor and drives the X-axis stepping motor to horizontally rotate. A silo material inventory dynamic detection method comprises the steps of receiving a detection starting command, starting detection if the radar level meter is in a standby state, and continuing current detection if the radar level meter is in a working state; detecting whether the rotation condition of the X-axis stepping motor is met or not; if the measuring point is the effective measuring point, enabling the Y-axis stepping motor to drive the radar level meter to rotate by an index, detecting every time when the radar level meter rotates by one index, and storing a measuring result; and when it is detected that the measuring point is not the effective measuring point, enabling the device to calculate the stock of the materials in the silo in the current state, meanwhile, enabling the device to automatically return to the original point, and enabling the radar level meter to measure the number of the materials each time.

Description

technical field [0001] The invention relates to the technical field of material detection, in particular to a dynamic detection device and method for silo material inventory. Background technique [0002] Silo is a commonly used storage method in various material storage. It has the advantages of large storage capacity, small footprint, and high degree of mechanization. It can be used to store various agricultural and industrial materials such as grain, feed, coke, and cement. [0003] The detection of silo materials generally adopts single-point radar level meter detection and multi-point laser principle detection. Single-point radar level meter detection is applicable to liquid materials and powdery solid materials with strong fluidity. The storage quantity of materials in the whole warehouse can be calculated through the detection height of single-point materials, but for large particles and low fluidity Solid materials, due to their large surface fluctuations and large ...

AI Technical Summary

Problems solved by technology

Single-point radar level meter detection is applicable to liquid materials and powdery solid materials with strong fluidity. The storage quantity of materials in the whole warehouse can be calculated through the detection height of single-point materials, but for large particles and low fluidity Solid materials, due to their large surface fluctuations and large surface fluctuations during the process of entering and exiting the warehouse, cannot be accurately detected; the multi-point laser principle detection equipment uses laser, infrared, etc. to perform multi-point detection on silo materials. The relatively high detection accuracy is also suitable for the detection of uneven material surfaces, but the dust is relatively large during the process of entering and exiting the warehouse, which causes great interference to lasers, infrared rays, etc., making the equipment unable to work normally
