Hierarchical Merchandise Security Control for Multi-Area Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current merchandise security systems face challenges in managing and controlling multiple areas and commodities effectively, as they often rely on peer-to-peer methods with fixed security codes, which are inconvenient, lack extensibility, and do not support flexible grading control, leading to potential security risks and operational inefficiencies.
Innovation Solution
A touch-type control system with a grading control mechanism, utilizing a main controller and auxiliary controllers to manage monitor devices through identifiable communication interfaces, allowing for flexible control ranges and privileges, enabling efficient management and power supply unification across different areas and commodities without the need for constant code updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each controller is programmed with built-in security codes using peer-to-peer method, then security control is improved, but operational convenience and extensibility deteriorate
Solution Approach 1:
The patent introduces a server as an intermediary between controllers and monitor devices. The server manages security codes, authentication, and control permissions centrally, eliminating the need for peer-to-peer code matching. Controllers communicate control requests to the server, which verifies permissions and relays commands to appropriate monitor devices, greatly simplifying operation while maintaining security.
Solution Approach 2:
The server provides universal control capabilities for multiple controllers and monitor devices across different regions and hierarchies. It handles various control operations (locking, unlocking, power management) and authentication types (password, fingerprint, facial recognition) in a unified manner, making the system adaptable to diverse scenarios without requiring separate control mechanisms for each device.
2Reliability
If fixed security codes are used in peer-to-peer control, then initial security is improved, but adaptability and extensibility deteriorate
Solution Approach 1:
The system transitions from static, fixed security codes to dynamic permission management. The server can dynamically assign, modify, and revoke control permissions based on user roles, regions, and time. When new monitor devices are added or control needs change, permissions are updated centrally without requiring physical code changes or system reconfiguration, enabling flexible adaptation and expansion.
Solution Approach 2:
The patent adds a hierarchical dimension to control management with multiple user levels (store manager, department manager, employee) and regional dimensions (different stores, departments, areas). The server manages permissions across these dimensions, allowing granular control assignment without affecting other parts of the system, thus enabling easy extensibility to new regions and device types.
3Device complexity
If controllers have control over adjacent areas, then system integration is improved, but security risks worsen
Solution Approach 1:
The server implements local quality control by assigning specific regional permissions to different controllers based on their roles and responsibilities. A controller can be granted permission to control monitor devices in specific regions (e.g., Electronics Department only) while being restricted from accessing other regions (e.g., Clothing Department). This granular permission management allows system integration across multiple areas while preventing unauthorized cross-region control and reducing security risks from internal threats.

AI summary
The invention provides a grading control system and a control device for merchandise security, including at least two controllers and a plurality of monitor devices, wherein the controller comprises at least one main controller and at least one auxiliary controller. The monitor device has an identifiable communication interface that is capable of communicating with the controller, and is configured to be communicable with the controller via the identifiable communication interface, and to be initialized by the controller in communication therewith. The monitor device initialized by the auxiliary controller can be controlled by the main controller and the auxiliary controller. In this system, the controller can control the monitor devices within a set range according to the different privilege/level settings, respectively. The range controlled by the controller in the same system may be divided into different grades of control, realizing the control of grading and sub-regions and reflecting grading management.
