Wireless Lock Control Using Signal Strength Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock control methods require user operations such as using a key, entering a password, or providing a fingerprint, imposing additional burden and disturbance on users.
Innovation Solution
A first wireless communication apparatus near a lock is used to establish a connection with a second wireless communication apparatus carried by the user, monitoring signal strength changes to determine the user's distance and movement relative to the lock, automatically unlocking or locking the lock based on this change without requiring user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic lock control based on signal strength monitoring is implemented, then user convenience is improved by eliminating manual operations, but device complexity increases due to wireless communication apparatus and signal monitoring requirements
Solution Approach 1:
The lock system automatically monitors signal strength changes and determines user proximity without requiring manual user input. The system serves itself by using the wireless communication apparatus to detect when the user approaches or leaves, automatically triggering lock or unlock actions without user intervention
Solution Approach 2:
The patent replaces traditional mechanical key-based locking systems with a wireless communication-based detection system. Instead of mechanical key insertion or physical interaction, the system uses signal strength monitoring to detect user presence and automatically control the lock state
2Reliability
If manual lock control operations are required, then security is maintained through user authentication, but user burden increases due to repeated operations
Solution Approach 1:
The system performs preliminary authentication by binding control permissions to the user's wireless communication apparatus in advance. When the user approaches, the system has already established the authorized connection and can immediately execute lock control actions without requiring additional authentication steps at the moment of use
3Extent of automation
If wireless communication apparatus is added for automatic detection, then automation is improved, but cost increases due to additional hardware components
Solution Approach 1:
The wireless communication apparatus serves multiple functions: it establishes communication connections for data transmission, monitors signal strength changes for proximity detection, and provides the basis for automatic lock control decisions. By making the wireless communication module multi-functional, the patent avoids needing separate dedicated sensors or detectors

AI summary
Embodiments of the present specification disclose a lock control method and apparatus, a medium, and a device. This solution can be applied to a trusted execution environment for execution. A first wireless communication apparatus is disposed in an adjacent area of a lock, a user carries a second communication apparatus, and control permission for the lock is bound to the second communication module. Once the user enters a signal sensing range of the first wireless communication apparatus, the first wireless communication module is triggered to establish a communication connection with the second wireless communication module. Signal strength of the communication connection changes with movement of the second wireless communication apparatus carried by the user. Therefore, a distance change trend of the second wireless communication apparatus relative to the first wireless communication apparatus is determined based on a monitored signal strength change trend. If it is determined that the user is moving close to the lock, the lock can be controlled to be in an unlocked state. If it is determined that the user is moving away from the lock, the lock can be controlled to be in a locked state.
