基于上位机控制的电焊机遥控操作系统的设计

针对目前采油厂普遍使用的直流电焊机在焊接过程中,需要根据金属质地的不同改变焊接电流大小,同时受空间限制,特殊工况下手工操作不便等问题,对基于上位机控制的电焊机遥控调整焊接电流外加装置进行了研究,提出了一种基于低功耗微处理器MSP430F149控制的无线射频遥控调流装置,该装置由电焊机控制端(下位机)和手持遥控端(上位机)两部分组成.手持遥控调流装置由微处理器MSP430F149,无线通信模块(nRF905),按键电路,显示模块,稳压电源及外围电路组成.电焊机控制装置由微处理器MSP430F149,直流电焊机,环境参数传感器,无线通信模块,稳压电源,有线无线转换开关及电流调节模块组成。实现了直流电焊机工作参数的远程调控,能够节约焊接施工的时间和人力成本,扩展焊机的使用场合。

Design of Remote Control Operating System for Electric Welding Machine Controlled by Host Computer

In view of the problems that the current widely used DC welding machines by oil production plant may face in the welding process, such as according to the different texture of the metal, changing the size of the welding current, space constraints, manual operation inconvenience under special conditions and other issues, after the research based on the host computer control welding machine remote control. This paper presents a radio frequency remote control device based on low power microprocessor MSP430F149, which consists of the control terminal (Client computer) and the remote control terminal (Host computer) of the welding machine. Hand held remote control device consists of the microprocessor MSP430F149, wireless communication module (nRF905), keyboard circuit, display module, power supply and external circuit components. Welding machine control consists of the microprocessor MSP430F149, DC welding machine, Parameter sensor, wireless communication module, power supply, cable wireless switch and current regulation module. To achieve the remote control of the DC welding machine operating parameters can save the welding time and labor costs, the use of extended welding machine occasions.
