Abstract
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.
