[Abstract]:Belt conveyor is a kind of continuous transportation equipment in modern production, which has the advantages of large capacity, long distance, low energy consumption, low freight, high efficiency, stable operation, convenient loading and unloading, suitable for bulk transportation and so on. Along with cars and trains, it has become the three main industrial means of transportation, and has been widely used in coal, mining, port, power, metallurgy, chemical and other fields. Conveyor belt is the key component of belt conveyor traction and bearing. In the process of use, due to various reasons, it will cause major broken belt or longitudinal tear safety accident and stop production, the loss of transportation materials, equipment damage, huge economic losses and casualties, seriously affecting safety in production. In order to ensure the safety of belt conveyor transportation, it is necessary to study a multi-view belt longitudinal tear detection system to realize the on-line detection of conveyor belt surface fault, to prevent the occurrence of longitudinal tear accident, to ensure the safety of belt conveyor transportation, and to avoid the occurrence of major safety accidents. In this paper, the acquisition and control module of video monitoring terminal in multi-view conveyor belt longitudinal tear detection system is studied, and a design scheme of video monitoring terminal acquisition and control module in multi-view conveyor belt longitudinal tear detection system is put forward, which realizes the high-speed acquisition, real-time storage and transmission of four-route matrix CCD signal. The hardware circuit of acquisition and control module is designed by using linear CCD sensor TCD1209D and FPGA XC3S500E chip of Xilinx company, including linear CCD sensor circuit, signal conditioning circuit, analog-to-digital conversion circuit, data acquisition control circuit, bus interface circuit and power supply circuit. On the Xi linx ISE software development platform, the FPGA software of the acquisition and control module is written with VHDL language, which mainly includes clock module, linear CCD sensor module, analog-to-digital conversion module, ping-pong storage module, bus interface module and data selection module. The timing simulation of FPGA program is carried out by using Modelism software. The experimental platform of multi-view conveyor belt longitudinal tear detection system is built, and the experimental results show that the acquisition and control module can realize the high-speed acquisition, real-time storage and transmission of four-route array CCD signal, and meet the design requirements. The acquisition and control module designed in this paper has the advantages of fast acquisition signal speed and good quality, and can be used in multi-view conveyor belt longitudinal tear detection system to realize the functions of high-speed acquisition, real-time storage and transmission of conveyor belt surface images, avoid the occurrence of safety accidents such as major belt breaking and longitudinal tear, stop production and casualties, reduce the loss and economic loss of transport materials, and improve production efficiency. It has remarkable economic and social benefits. It has a wide application prospect in coal, mine, port, electric power, metallurgy, chemical industry and other fields.
