Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] The invention provides a detection device. The basic scheme of the detection device is: an online detection device for the quantity of large-scale grain storage. A pressure sensor is arranged between them; the outer contour of the casing is in the shape of a regular hexagon or an equilateral triangle in a section perpendicular to the up and down direction.

[0036] The bearing plate concentrates the large-area grain gravity acting on the bottom of the warehouse on the force-bearing surface of the pressure sensor with a smaller area.

[0037] Further, it is preferable to place the pressure sensor at the center of the entire device, that is, the pressure sensor is located in the center of the detection device, and the pressure sensor is evenly distributed with a number of positioning support guide rods in the circumferential direction; the positioning su...

Abstract

The invention relates to an online granary stored grain detection device, a detection unit and a pressure sensor measurement method. The detection device comprises a housing. The housing comprises a bearing plate and a base which are arranged up and down; pressure sensors are arranged between the bearing plate and the base; and the cross-section shape of the outer contour of the housing in the direction perpendicular to the up and down direction is a regular hexagon or an equilateral triangle. According to the device in the invention, a gravity bearing surface in a local region is enlarged, and the total number of the pressure sensors used for measurement is not increased; compared with the device with common pressure sensors, the measurement area of a single place is increased by many times; and for the whole granary bottom, the total number of the high-cost pressure sensors is actually reduced, and thus the total cost of the on-line detection system is greatly reduced.

Description

technical field [0001] The invention relates to an online detection device for grain storage, a detection unit and a pressure sensor measurement method. Background technique [0002] The on-line detection of granaries is very important, mainly because the accumulative weighing method can only be used to complete the detection of the quantity of grains when they leave or enter the warehouse once. Large-scale relocation of food is also required, and the cost of manpower is extremely high, and the efficiency is low and the workload is heavy. For large granaries, due to the large area at the bottom of the granary and the weight of the grain, general weighing equipment cannot be detected online. Existing methods for detecting the quantity of stored grain mainly include measurement and calculation methods and multi-point measurement and weighing methods. The measurement and calculation method is a detection method that calculates the grain quantity in the granary by measuring an...
