Intelligent Safety Entrance Exit Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial settings, maintenance personnel are at risk of being locked in hazardous areas due to the lack of physical keys for intelligent Lock Out Tag Out (LOTO) systems, allowing external personnel to inadvertently lock them in, posing a safety hazard.
Innovation Solution
An intelligent security entrance/exit management system with a removable lock cylinder and guide post, featuring an identification module and control module that authorize personnel access and ensure only authorized individuals can unlock or lock doors, preventing external locking and ensuring safe exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If intelligent LOTO systems are implemented without physical keys, then automation and intelligence of equipment operation are improved, but maintenance personnel may be accidentally locked in hazardous areas by external personnel, worsening safety reliability
Solution Approach 1:
The patent introduces an intermediary control system that mediates between the intelligent LOTO operation and the physical locking mechanism. The control system monitors the state of maintenance personnel inside hazardous areas and intercepts locking commands from external personnel, preventing accidental locking while maintaining the intelligence and automation benefits of the LOTO system.
Solution Approach 2:
The patent implements a feedback mechanism where the control system continuously monitors whether maintenance personnel are inside hazardous areas and provides real-time feedback to prevent locking operations. This feedback loop ensures that the locking action is blocked when maintenance personnel are present, resolving the safety reliability issue while preserving automation.
2Reliability
If access control is implemented in hazardous areas, then safety protection of hazardous areas is improved, but authorized personnel cannot be distinguished from unauthorized personnel, worsening access control effectiveness
Solution Approach 1:
The patent replaces traditional mechanical key-based access control with an electronic identification and control system. The system uses electronic identification methods (such as cards, biometrics, or RFID) to distinguish authorized from unauthorized personnel, and the control system automatically manages locking and unlocking operations, improving both safety protection and operational ease.

AI summary
In an intelligent safety entrance/exit management system, method and device, by identifying the right status of the person who triggers the unlocking and the movement status of the lock cylinder moving out from the keyhole of the lock body to control the period of authorization for triggering the opening of the door, to realize that after the person who has trigger the unlocking pulls out the lock cylinder of the lock on the area door from the keyhole of the lock body, no one else can lock the door of the area. Also by tracking the person appearing in the video and identifying the direction of movement; when the person in the identification video enters the protective area, it identifies whether it is the person who triggers the unlocking; if not, it will issue a trailing alarm.
