Design of Control System of Dosing Machine Based on PLC
-
摘要: 为了提高工业雷管自动装填线工艺流程的安全性，提出了一种基于PLC的加药机器手控制系统的设计方案，详细介绍了该系统的结构组成及软、硬件设计。该系统通过控制电动机的正反转实现加药过程的自动化，具有手动和自动两种操作方式，转换灵活，还可通过上位机监控界面实时显示加药系统的运行状态，并具有声光报警功能。测试结果表明，该系统工作稳定，可靠性较高，提高了生产线的工作效率，降低了工人的劳动强度。Abstract: In order to improve security of technique process of automatic filling line of industrial detonator, a design scheme of control system of dosing machine based on PLC was put forward and composition and designs of software and hardware of the system were introduced in details. The system realizes automation of dosing process by controlling motor reversing and has manual and automatic operating ways with flexible switch. Besides, it can real-timely display running status of dosing system on monitoring interface of upper computer and has sound and light alarm function. The testing result showed that the system runs stably and has high reliability, which improves working efficiency of production line and reduces labor intensity.
