AI Technical Summary
Technical Problem
In automated storage and retrieval systems (AS/RS), the space outside the tracks for rail vehicles is limited, and personnel entering may compromise their safety.
Method used
The PLC controller is electrically connected to the power supply and safety door switch module of the rail vehicle. It receives the trigger signal from the safety door switch module and controls the operation status of the rail vehicle, including the cutting off and restoration of power, to ensure personnel safety.
Benefits of technology
This system ensures that the power supply to the rail vehicle is interrupted when the safety door is opened to ensure personnel safety, and that the power supply is restored when personnel leave to avoid endangering them.

Abstract
This disclosure relates to an automated storage and retrieval system (AS / RS) management system and method. The AS / RS management system includes: a rail vehicle that runs between racks; and a PLC controller electrically connected to the power supply and safety door switch modules of the rail vehicle, used to receive trigger signals from the safety door switch modules and control the operating status of the rail vehicle based on the trigger signals. In this application, by electrically connecting the PLC controller to the power supply and safety door switch modules of the rail vehicle, different on / off states of the safety door switch modules trigger the PLC to issue commands to control the power cut-off and power supply of the rail vehicle. This ensures that when the safety door is opened and personnel enter, the power supply to the rail vehicle is interrupted, thereby helping to ensure the safety of personnel entering.
