Abstract

The invention discloses a laser weighing system for belt conveying and a weighing method thereof. The laser weighing system comprises a transmission belt, a laser scanner, a displacement encoder, a data transmitter, a data processing computer, a database server, an Ethernet and a camera. The weighing method includes the steps that a corresponding two-dimensional cross section diagram is generated, a displacement diagram of the current transmission belt is calculated, a transmitted object surface skeleton diagram in the transmission process of the transmission belt is fitted, the size of a transmitted object is calculated, the flow volume is calculated out, and the weight of the transmitted object is finally obtained. By means of the method and the system, a model is set up for the transmitted object, the accurate numerical value of the position of a current material is fed back to a corresponding mechanical device, so that real-time checking is achieved, the size and the weight of a cargo on the current transmission belt are checked and measured, and finally the purpose of reducing weighing errors is achieved.

Description

technical field [0001] The invention relates to the field of belt conveying, in particular to a laser weighing system and a weighing method for belt conveying. Background technique [0002] The belt transmission system is the most ideal continuous transportation system when transporting coal mines. Compared with other transportation systems (such as locomotives), it has the advantages of long transportation distance, large transportation volume, continuous transportation, etc., and it is reliable in operation and easy to realize automation and centralization. Control, especially for high-yield and high-efficiency mines, the belt transmission system has become a key link in coal mining mechatronics technology and equipment. [0003] At present, my country has a large number of belt conveyor systems in power plants, coal mines, metallurgy, ports and terminals. Most of the existing belt conveying systems use electronic belt scales to weigh bulk materials. Electronic belt sca...
