摘要
为了解决某大型钢结构厂生产加工的焊件通过人工推车输送到达工位的问题,设计了运输车呼叫系统,通过该系统能有效地将焊件自动输送到达所呼叫的工位。基于PLC核心控制技术,对控制系统进行软、硬件设计,根据控制要求和电气设计相关规定,设计电气控制系统原理图,PLC接口地址分配表,以实例分析了七段数码管限流电阻计算方法,并提供系统主要元器件明细表;设计系统主程序流程图和相关功能程序,并通过触摸屏仿真实现软件功能测试,再通过现场安装调试及生产运行。研究结果表明:该控制系统完全达到控制要求,且系统稳定可靠,控制灵活方便,提高了生产效率。
In order to solve the problems of transporting the welding parts to the work place by means of manual trolleys,in a factory which manufactured large steel structure,a transport vehicle calling system was designed. The system could transfer the welding parts to the positions automatically and effectively. Based on PLC core control technology,the software and hardware of the control system were designed.The electrical control system schematic and PLC interface address allocation table were designed. The calculation method in the limit current resistance of the seven segment digital tube was analyzed by examples. The main components of the system detail table were provided. A flow chart of the main program and the related functions programs were included. The requests of the software function test could get by the touch screen simulation. And after it was passed by the site installation,then was produced. The research results show： the control system fully meets the control requirements. It is stable and reliable,flexible and convenient to control. It can improve the production effectively.
