Belt conveyor is one of the most used continuous transportation equipment, and it is widely used in ports, mines, steel mills, power plants and other fields. Due to the falling of the liner, the sharp iron adsorbed by the iron remover, and the improper installation of the cleaner, etc., the conveyor belt may be torn and scraped, resulting in huge economic losses, and even if it can be repaired, it will require considerable manpower and time, which will have a great impact on the normal operation. How to warn the occurrence of belt tearing through intelligent means has become an important problem to be solved urgently in belt safety production.
In response to the pain points and scene needs of the industry, Weijing Intelligent has independently developed online real-time warning of tearing problems in the belt conveying process, which has the characteristics of high sensitivity, high reliability, simple structure, easy installation and maintenance, etc., to achieve the purpose of safe production and intelligent control.
0 1 Stereo vision technology as the basis
The belt tear sensor adopts stereo vision technology system, through the line laser + 3D vision scheme for point cloud data modeling and artificial intelligence algorithm to complete the online detection of belt tear, using non-contact installation, no need to calibrate on site, no need to change the on-site environment, fast implementation, easy system maintenance, is the best solution for belt conveyor safety monitoring.

02Powerful performance assistance
The belt tear sensor has a strong detection performance, which can detect and alarm the belt tear for the belt speed of 6m/s, and can output the length, width and depth of the belt tear, with a detection accuracy of up to 2mm and a detection accuracy of more than 99%, which can not only monitor the longitudinal tearing situation in real time, but also detect the transverse tear and belt damage to meet the application needs of various scenarios such as underground and uphole.
03Strong environmental adaptability
In terms of installation and implementation, the belt tear sensor is more in line with the rapid landing application of the site, directly installed at the bottom of the belt, without supplemental light, and can be used in dark environments, outdoors, by windows, lighting and other venues, suitable for straight, U-shaped, V-shaped and other types of conveyors, and can adapt to the high-precision detection of vibration, on-site dust environment, water stains on the surface of the belt and cinder in the process of belt conveying, and has strong environmental adaptability.
04Generalized industry applications
The belt tear sensor adopts a generalized product design, which can be installed and used immediately for different types of belts and belts of different widths, and is suitable for coal transportation, bulk material transportation, port transportation, power plant transportation and other industries, greatly reducing the project cycle. In terms of hardware, the overall intelligent terminal design is adopted, which does not require the operation of the industrial control host, which is more suitable for data transmission and low latency in high-speed dynamic scenes, and reduces the cost of other hardware.
05Assist belt safety production monitoring
The belt tear sensor can effectively reduce the potential safety hazards caused by the belt tear problem, and establish a dynamic online detection system, emergency interlocking PLC shutdown protection, avoid accidents, and greatly strengthen the intelligent detection of traditional equipment.
