Information Management System Repeater Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information management systems, repeaters often acquire detection data from terminal devices that have already been acquired by other repeaters, leading to repetition of communication connections and disconnections, which degrades the overall efficiency of the system.
Innovation Solution
Implementing a system where repeaters maintain terminal device lists indicating the source devices and latest receipt times of detection data, allowing them to determine whether to re-acquire data based on notified latest receipt times via a server, thereby avoiding redundant data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeaters independently acquire detection data from terminal devices without coordination, then each repeater can obtain the latest data, but communication connections are repeated causing system efficiency degradation
Solution Approach 1:
The patent merges the data acquisition functions of multiple repeaters by introducing a server that coordinates their operations. The server consolidates terminal device lists and latest receipt time information, allowing repeaters to share acquired data rather than independently re-acquiring it, thus eliminating redundant communications while maintaining data freshness
Solution Approach 2:
The system implements feedback mechanisms where repeaters report acquired data information to the server, which then notifies other repeaters of the latest receipt times. This feedback loop enables repeaters to adjust their acquisition behavior based on system-wide state, preventing redundant connections while ensuring data currency
2Loss of information
If repeaters frequently connect to terminal devices to acquire updated detection data, then data currency is maintained, but communication overhead increases and system efficiency decreases
Solution Approach 1:
The server performs preliminary actions by maintaining updated terminal device lists and latest receipt time information before repeaters need to acquire data. RepeaterS can query this pre-prepared information to determine whether acquisition is necessary, avoiding unnecessary connection attempts and reducing communication overhead
Solution Approach 2:
The server acts as an intermediary between repeaters and terminal devices, managing the terminal device lists and coordination logic. This intermediary role prevents direct redundant communications between repeaters and terminal devices, reducing communication time while ensuring data currency through centralized management
