【摘要】：带式输送机是一种现代化生产中的连续运输设备,具有运量大、运距远、能耗小、运费低、装卸方便、适合于散料运输等特点,已广泛应用于煤炭、矿山、港口、电力、冶金、化工等领域。输送带是带式输送机的牵引和承载的关键部件。由于带式输送机安装调整不当、落料点落料不正、长期在恶劣环境下使用等原因,会造成输送带发生跑偏、表面损伤和纵向撕裂等故障。如果这些故障得不到及时检测和处理,会引发重大断带和纵向撕裂等安全事故,造成停产、运输物料的损耗、设备的损坏和人员的伤亡,严重影响安全生产。为了保证带式输送机运输的安全,因此需要研究一种多视点输送带纵向撕裂检测系统,实现对输送带跑偏、表面损伤和纵向撕裂等故障的在线检测,避免重大纵向撕裂安全事故的发生,提高检测的全面性。本文针对多视点输送带纵向撕裂检测系统中视频监测终端的处理传输模块进行了研究,提出了一种多视点输送带纵向撕裂检测系统视频监测终端的处理传输模块的设计方案,采用四路线阵CCD传感器同时采集输送带图像,实现了对四路输送带图像数据的获取、压缩编码、处理及传输,提高了输送带图像采集范围;采用TI公司的DSP(TMS320C6748)设计了处理传输模块的硬件电路,包括数据传输接口电路、数据处理器电路和以太网接口电路;根据输送带图像的灰度特点,提出了一种基于log变换的输送带图像JPEG压缩编解码及特征增强算法,实现了对输送带图像的压缩编码和纵向撕裂部分的特征增强,并在MATLAB平台上进行了仿真实验,验证了该算法的有效性;在CCS软件开发平台上,利用C语言编写了基于SYS/BIOS操作系统的DSP软件,搭建了多视点输送带纵向撕裂检测系统中视频监测终端的处理传输模块的实验平台,对所设计的处理传输模块进行了测试,结果表明该模块能够实现对四路输送带图像数据的采集、压缩编码、特征增强及以太网传输等功能。本课题研究的处理传输模块可应用于多视点输送带纵向撕裂检测系统中,具有输送带图像采集范围大、压缩效率高、实时性强等优点,在煤炭、矿山、港口、电力、冶金、化工等领域具有广泛的应用前景,能够避免重大纵向撕裂安全事故的发生和人员伤亡,减少运输物料损耗、设备损坏和经济损失。
[Abstract]:Belt conveyor is a kind of continuous transportation equipment in modern production. It has the characteristics of large capacity, long distance, low energy consumption, low freight, convenient loading and unloading, suitable for bulk transportation and has been widely used in coal, mines, ports, electric power, metallurgy, etc. Chemical industry, etc. Conveyor belt is the key component of belt conveyor. Due to improper installation and adjustment of belt conveyer, improper blanking point, long term use in bad environment and other reasons, the belt will be run off, surface damage and longitudinal tear will occur. If these faults can not be detected and dealt with in time, it will lead to serious safety accidents such as broken belt and longitudinal tear, which will result in shutdown, material loss, equipment damage and casualties, which will seriously affect 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 belt deviation, surface damage and longitudinal tear. Avoid the occurrence of major longitudinal tear safety accident, improve the overall detection. In this paper, the processing and transmission module of the video monitoring terminal in the multi-view belt longitudinal tear detection system is studied, and a design scheme of the video processing transmission module of the multi-view belt longitudinal tear detection system is proposed. The four path array CCD sensor is used to collect the images of the conveyor belt at the same time. The image data of the four conveyors are obtained, compressed and coded, processed and transmitted, and the range of the image acquisition of the conveyer belt is improved. The hardware circuit of processing transmission module is designed by DSP (TMS320C6748) of TI Company, including data transmission interface circuit, data processor circuit and Ethernet interface circuit. In this paper, a JPEG compression coding and decoding algorithm and feature enhancement algorithm based on log transform for conveyor belt image are proposed. The feature enhancement of the compression coding and longitudinal tearing part of the conveyor belt image is realized, and the simulation experiment is carried out on the MATLAB platform. The validity of the algorithm is verified, and the DSP software based on SYS/BIOS operating system is programmed by C language on the CCS software development platform. The experiment platform of the processing and transmission module of video monitoring terminal in the longitudinal tear detection system of multi-view conveyor belt is built, and the designed processing transmission module is tested.
