数模转换技术在电子束焊机控制系统中的应用

Application of A/D and D/A technology in the control system for electron beam welder

根据电子束焊机控制系统的要求,利用数模转换技术实现了对电子束焊机各主要系统的控制.对电子束焊机的高压控制系统、束流控制系统和工作台运动控制系统的特点进行了分析,提出用PLC的特殊功能模块技术设计系统控制软件.硬件采用FX2N-128MT为中央控制系统实现对整机设备的控制.设备运行表明:设计的硬件和软件工作可靠,符合电子束焊接工艺的需要.

According to the requirements of controlling systems for electron beam welder, A/D and D/A technology to control EBW are used to control EBW. The control systems such as high voltage control system, control system for current of electron beam, running control system for work bench are analyzed.The software design of control system is put forward with PLC special function module .The FX2N-128MT is adapted to control the machine for center control system. The operation shows the hardware and software designed by us work reliably and meet the technology requirements of electron beam welding.
