架空乘人装置用隔爆兼本安型控制箱的研制

针对采用继电器控制方式控制架空乘人装置存在维护困难、工作效率低、安全性能差等问题,提出了一种基于PLC控制的架空乘人装置用控制箱的研制方案,介绍了该控制箱的硬件、软件设计及功能特点。该控制箱采用PLC作为控制核心、MT6070I系列触摸屏作为人机界面,实现了架空乘人装置及时停车、急停闭锁、状态及时显示、保护等功能。实际应用表明,该控制箱运行稳定,实现了全自动无人值守运行,提高了架空乘人装置的安全性和可靠性。

Development of Control Box with Flameproof and Intrinsic Safety for Aerial Passenger Device

In view of problems of difficult maintenance,low efficiency and poor safety performance existed in aerial passenger device controlled by relays,a development scheme of control box for aerial passenger device based on PLC was proposed,hardware design,software design and function characteristics of the control box were introduced.The control box uses PLC as control core and MT60701 touch panel as man-machine interface,which realizes functions of in-time parking,sudden stop interlock,in-time display and protection of state of aerial passenger device.The practice proved that the control box is stable in running,which realizes automatic and unmanned operation,and improves safety and reliability of aerial passenger device.
