摘要
针对传统焊接生产过程中环境复杂且焊机分散导致焊接参数难以进行有效监控的现状,设计基于STM32和WiFi技术的焊接参数无线采集与传输系统。系统采用以STM32为核心的嵌入式采集板对焊接参数进行采集及运算处理,芯片与WiFi模块间采用SPI通讯,采集数据打包后经WiFi传输网络发送至上位机;上位机监控平台由LabVIEW编制,对焊接车间焊机工艺参数进行监控并通过定时发送功能对下位机发送时序进行控制。测试表明,系统可实现对焊机焊接过程参数的实时采集及无线传输,采集频率高,传输速度快,有助于促进传统焊接生产向信息化制造转型升级。
In the traditional welding production process,because of the complicated environment and the dispersed welding machines,the welding parameters are difficult to be effectively monitored. For this situation a welding parameter acquisition and wireless transmission system based on STM32 and WiFi technology has been designed. This system adopts embedded acquisition board with STM32 as the core to collect and process the welding parameters. STM32 chip communicates with WiFi module through SPI interface,collects and packages data,then sends it to the host computer via WiFi transmission network; The host computer monitoring platform is compiled by LabVIEW,monitors the welding parameters of welding machine in the welding shop and controls the transmission timing of the slave computer through the timing transmission function. The test shows that this system realizes the real-time acquisition and wireless transmission of welding parameters,has high acquisition frequency and fast transmission speed,which will help promote the transformation and upgrading of traditional welding production to information-based manufacturing.
