Grain amount monitoring and in-warehouse video monitoring device and system

Abstract

The invention discloses a grain amount monitoring and in-warehouse video monitoring device, which comprises: a main cylinder, an auxiliary cylinder, a horizontal motor, a fixing and leveling device, avertical motor, a power supply, a driving controller, a control device, a tilt angle sensor, a high-definition network machine core and a laser ranging sensor, wherein the horizontal motor is arranged at the top end of the inner wall of the main cylinder, and the fixing and leveling device is located above the main cylinder and is rotatably connected with the horizontal motor; the vertical motoris arranged on the side wall, adjacent to the auxiliary cylinder, of the main cylinder, and the vertical motor is connected with the auxiliary cylinder by means of a main and auxiliary cylinder connection sealing device; the power supply and the driving controller are installed inside the main cylinder; the control device, the tilt angle sensor, the high-definition network machine core and the laser ranging sensor are all installed inside the auxiliary cylinder. The grain amount monitoring and in-warehouse video monitoring device and a grain amount monitoring and in-warehouse video monitoringsystem disclosed by the invention can measure the amount of grain stock precisely in real time, can obtain full-color high-definition pictures in the dark environment of an enclosed warehouse, monitorthe real scene in the warehouse comprehensively at 360 degrees without dead angle, have the advantages of simple structure and low production cost, and can be popularized and applied.

Description

technical field [0001] The invention relates to a video monitoring device and system, more specifically to a grain quantity monitoring and warehouse video monitoring device and system, belonging to the field of grain storage quantity monitoring and warehouse video monitoring. Background technique [0002] The national grain reserve is an important strategic material related to the national economy, the people's livelihood and the national economic security. Grain authorities need to timely and accurately grasp its quantity and check the grain status to ensure food security; Libraries cost a lot. [0003] The traditional method of measuring the amount of grain is generally to use a manual ruler to measure, or use a hand-held laser rangefinder to measure the plane size of the grain pile in two directions, and then calculate the volume according to the height of the measured grain pile, and then calculate the grain according to the provided bulk density. quantity. Although te...

Problems solved by technology

Although technicians in the grain industry have conducted research on related technologies, there are still many key technologies for grain quantity monitoring that have not yet been resolved.

First, in terms of grain volume measurement, some people are currently using non-contact monitoring technology to conduct related research, for example: the patent application number 201210224186. The guide rails are arranged in the bungalow, and the three-dimensional laser radar is used to scan and use the high-speed rotating prism to measure the volume. However, this technology does not consider the large amount of dust during the grain entry and exit operations and the toxic gas in the grain fumigation process (H 2 S) corrosion and other dust-proof and anti-corrosion problems will seriously affect the walking accuracy of the guide rail or even damage it, and the reliability and stability of the measurement results cannot be guaranteed. High, not suitable for popularization and application in a large number of large granaries; other similar technologies such as ultrasound, image analysis, etc. also have the above problems

Second, the bulk density of grain piles stored in the granary will change with the way of grain in and out, ventilation, fumigation, surrounding environment (with or without vibration), storage time, etc. during the grain storage process, and will affect the final calculation of the warehouse capacity. greater impact, but this issue has not yet been resolved
