Solution Overview

Problem

Existing equipment management systems struggle with identifying the cause of communication abnormalities between controllers and devices due to various potential causes, leading to prolonged troubleshooting times.

Innovation Solution

An air conditioning management controller equipped with an initial communication processor for establishing connections and a periodic communication processor for confirming normal communication states, along with a display information generator to distinguish between initial and periodic communication abnormalities, facilitating quick identification of the cause.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If communication confirmation is periodically performed between the controller and each device to detect communication abnormality, then the reliability of communication monitoring is improved, but the time required to identify the cause of abnormality increases

Engineering Contradiction:
Improvecommunication abnormality detectionVSAvoidtroubleshooting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments communication abnormality detection into two distinct phases: initial communication establishment detection and periodic communication status detection. By dividing the monitoring process and associating each phase with specific cause information (initialization causes vs. periodic causes), the system enables administrators to quickly identify the appropriate cause category without extensive troubleshooting, thus reducing loss of time while maintaining reliable detection.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If various communication abnormality causes are monitored comprehensively, then the measurement precision of abnormality diagnosis is improved, but the device complexity increases

Engineering Contradiction:
Improveabnormality cause identificationVSAvoidcommunication processing system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by categorizing communication causes into distinct groups: initialization causes (occurring during initial communication establishment) and periodic causes (occurring during periodic communication confirmation). This segmentation allows the system to provide comprehensive cause identification without requiring a single complex processing system, as each cause type can be handled by dedicated processing logic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary component (the communication cause notification unit) that mediates between the communication processing system and the administrator. This intermediary translates complex communication abnormality data into user-friendly cause information, improving measurement precision for end-users while shielding them from the underlying system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If detailed communication state information is displayed to administrators, then the ease of operation for identifying causes is improved, but the loss of information increases due to the need to process and display multiple cause types

Engineering Contradiction:
Improvecause identificationVSAvoidcommunication cause data
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent employs an intermediary (the communication cause notification unit) that selectively presents cause information to administrators based on the current communication phase. This intermediary filters and organizes detailed communication data, making it easier for administrators to operate while preserving all necessary information by presenting it in a structured, phase-appropriate manner rather than losing it through inadequate filtering.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An air conditioning management controller (20) as an equipment device management apparatus includes an initial communication processor (221), a periodic communication processor (222), a display information generator (224), and a display (242). The initial communication processor (221) executes communication establishment processing by initial communication with an equipment device to be managed for which communication has not been established. The periodic communication processor (222) periodically executes communication confirmation processing by periodic communication for confirming whether a communication state is normal with respect to an equipment device for which communication has been established by the communication establishment processing. When recognizing that a communication abnormality has occurred with the equipment device based on an execution result of the communication establishment processing and an execution result of the communication confirmation processing, the display information generator (224) generates display information for distinguishing whether the communication abnormality is an abnormality of the initial communication or an abnormality of the periodic communication. The display (242) displays the generated display information.
