摘要
为了快速准确地检测CO2气体保护焊的熔滴短路过渡电信号,设计了一种以MSP430F5529单片机为核心的电信号数据采集系统。霍尔传感器、单片机和上位机组成硬件系统。单片机内部同时集成模数转换模块和USB模块,简化了硬件电路,系统的抗干扰能力增强。电信号的模数转换和数据存储按照重复序列通道模式进行,该过程可自动完成。数据由USB端口按照该单片机特有的数据管道模式高速传送给上位机。单片机的USB模块在数据管道模式下无需驱动,而且该模式的规则简单,调用简单的函数即可实现传送单片机中任意位置和任意大小的数据,传送速度保持不变。
In order to quickly and accurately detect the electrical signals of short-circuit droplet transition in the CO2 gas shielded welding,a electrical signal data acquisition system is designed,which MSP430F5529 MCU is as the core.The hardware system consists of Hall sensor,microcontroller and the host computer.Because analog to digital conversion module and USB module are integrated in microcontroller at the same time, the hardware circuit is simply and anti-jamming capability of the system is enhanced.Signal analog- digital conversion and data storage operate by repeat sequence channel mode, the process can be completed automatically. According unique data pipe mode,data are transferred from MCU to the host computer at high speed through the USB port of the MCU.USB module of the MCU in the data pipe mode does not require the driver,the rules of the model is simple,the data transmission of anywhere and any size in MCU can be realized by calling some simple functions, and transmission speed remains unchanged.
