【摘要】：焊接技术作为19世纪末期、20世纪初期发展起来的重要金属加工工艺之一,已随着电力电子技术、智能控制技术、计算机技术以及通信技术的不断更新,被大量应用在各个基础部门。然而,目前国内焊接装备及系统的自动化水平较低,存在有线监控的弊端,焊接作业的生产管理、质量监督与监测数字化应用欠缺,相关人员难以实时监控焊接过程,导致大量焊接有效数据分散、难以随时跟踪、分析,焊接参数可追溯性差等状况。针对以上问题,结合数字化焊接电源较模拟电源开发潜力大的优势,本文首先搭建了数字化焊接电源平台,其数字化控制系统采用TMS320F28033DSP芯片作为控制核心,为实现焊接过程的监测及控制提供了良好的运行基础为了提高焊接质量及加快智能焊接技术的进程,进行焊接质量无线监控及焊接过程控制,在数字化焊接电源的基础上,本文随后设计了一套基于蓝牙4.0的焊接在线监测系统,对无线通信模块、焊接主控板及PC机进行了相关软硬件设计,实现了焊接过程参数与焊接管理的信息化、数字化。系统采用自定义的焊接参数和命令通信协议,基于蓝牙4.0协议栈解决了稳定可靠的无线数据传输的问题,上位机软件结合VS 2010提供的MFC平台,采用多线程设计方法,并利用SQL Server数据库实现工艺参数的保存、信息的查询和数据的分析等功能,为焊接质量的分析提供依据,经测试,该系统运行稳定可靠。该系统既推进了焊接装备和焊接工艺的智能化、网络化发展,又降低了生产成本,有利于大幅度减少了焊接质量问题,使焊接行业朝着信息化、集成化发展。
[Abstract]:As one of the important metal processing technologies developed in the late 19th century and the early 20th century, welding technology has been continuously updated with the power electronics technology, intelligent control technology, computer technology and communication technology.It is widely used in various basic sectors.However, at present, the level of automation of welding equipment and system in China is relatively low, and there are disadvantages of wire monitoring, the production management of welding operation, the digital application of quality supervision and monitoring, and the difficulty of real-time monitoring of welding process.It results in a large number of effective welding data scattered, difficult to track, analysis, welding parameters poor traceability and so on.In view of the above problems, combined with the advantages of digital welding power source than analog power source development potential, this paper first built a digital welding power source platform, its digital control system uses TMS320F28033DSP chip as the control core.Then, a welding on-line monitoring system based on Bluetooth 4.0 is designed. The software and hardware of wireless communication module, welding main control board and PC are designed, and the information of welding process parameters and welding management are realized.The SQL Server database is used to save the process parameters, query the information and analyze the data, which provides the basis for the analysis of welding quality. The test results show that the system is stable and reliable.The system not only promotes the intelligent and networked development of welding equipment and welding process, but also reduces the production cost, which is beneficial to greatly reduce the welding quality problems, and makes the welding industry develop towards information and integration.
