Independent Monitoring Module for Communication Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication device monitoring systems rely on CPU subsystems for board status monitoring, which can fail due to high temperatures or voltage issues, and share the same voltage as the components being monitored, leading to unreliable operation.
Innovation Solution
A non-intelligent monitoring module attached to the service board reports its status to a centralized management device via a serial bus, separating the monitoring circuit from the circuit under monitor and providing an independent power supply, ensuring continued operation even if the CPU subsystem fails or voltage becomes abnormal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the CPU sub-system on the main control board or service board is used to monitor and manage board status, then the monitoring function is integrated and simple to implement, but the monitoring system becomes unreliable when the CPU fails due to high temperature or voltage issues
Solution Approach 1:
The patent divides the monitoring system into two independent parts: a monitoring module that collects status information from board components, and a CPU sub-system that processes and manages the monitoring data. This segmentation allows the monitoring function to operate independently from the CPU, ensuring that monitoring continues even when the CPU fails due to high temperature or voltage issues.
Solution Approach 2:
The patent extracts the monitoring function from the CPU sub-system by creating a separate monitoring module. This extracted monitoring module directly interfaces with board components through dedicated monitoring buses, removing the monitoring function's dependency on the CPU's operational status and power supply.
2Reliability
If the monitoring parts share the working voltage of the board, then the voltage supply is simple and unified, but the monitoring parts become unable to work normally when the voltage becomes abnormal
Solution Approach 1:
The patent applies local quality by providing the monitoring module with a dedicated power supply voltage that is separate from the board's working voltage. This localized power supply ensures that the monitoring module maintains its operational capability even when the board's working voltage becomes abnormal, as the monitoring module's power supply is not affected by voltage fluctuations on the board.
3Reliability
If the CPU sub-system monitors board status, then the monitoring information flows through the CPU, but the monitoring fails when the CPU cannot work normally
Solution Approach 1:
The patent introduces a monitoring module as an intermediary between the board components and the CPU sub-system. This intermediary collects monitoring information directly from board components through monitoring buses and transfers it to the CPU for processing. The intermediary ensures that monitoring information can be collected and transmitted even when the CPU cannot perform its normal functions, maintaining monitoring continuity.

AI summary
A system, devices, apparatuses and a method for monitoring and managing are described, which includes a system centralized management device and at least one monitoring module. The monitoring module is configured to monitor the working status of a service board. The system centralized management device, which is connected to the monitoring module by the serial bus, and is configured to perform centralized management to the at least one monitoring module. Because the system centralized management device performs centralized management on the monitoring module of the service board by the serial bus, the reliability of monitoring and managing the service board is improved.
