Measuring System Access Data Synchronization Across Field Components

The patent merges separate user management schemes at sensor, transmitter, and controller levels into a unified hierarchical system. A central user management entity maintains master user data that is distributed to all devices, eliminating the need for separate administrative management at each device while maintaining security through synchronized access control.

The patent creates a universal user management framework that operates across multiple device types and hierarchical levels. The same user management principles and data structures are applied consistently from sensor level through transmitter to controller, providing a multi-functional solution that handles authentication, authorization, and access control uniformly throughout the measuring system.

The patent implements periodic synchronization where access data is updated and distributed across the system at scheduled intervals or triggered by specific events rather than continuously. This reduces communication overhead and energy consumption while maintaining data consistency, as devices only need to synchronize when changes occur or at predetermined times.

The patent performs preliminary user data management at a central level before distribution to individual devices. User data is prepared, validated, and organized in advance, then efficiently distributed to transmitters and sensors only when changes occur. This preliminary processing reduces the frequency and volume of communications required across the network.

The patent combines multiple device-specific password and access right management systems into a unified hierarchical structure. A single user identity and access rights are maintained at the controller level and automatically distributed to transmitters and sensors, eliminating the need for administrators to manage separate credentials at each device level while maintaining security through synchronized access control.

The patent uses copying to distribute user data from a central master copy at the controller level to individual devices. When user data changes, the updated information is automatically copied and propagated to all relevant transmitters and sensors, ensuring consistency across the system without requiring manual updates at each device, thus reducing administrative time significantly.

The patent implements a dynamic user management system where devices operate autonomously using locally stored user data, but automatically update and synchronize with the central controller when changes occur. This dynamic approach maintains device-level autonomy for local operations while enabling efficient centralized management for system-wide changes, combining the benefits of both autonomous and centralized approaches.

The patent enables devices to self-manage user access using locally cached user data from the controller. Devices can independently authenticate users and enforce access rights without continuous controller intervention, improving efficiency. When user data changes, the system automatically updates devices, allowing them to self-service while maintaining synchronization with the central management system.
