Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In conventional electric power systems, implementing priority control for messages flowing through a common bus is challenging due to the unique message transmission methods of internal application units and the limitations of dispatcher-based priority control in the common bus method.

Innovation Solution

A message control program that associates message types with service names and communication method identification information, allowing each message control unit to dynamically change communication methods based on specified information, enabling priority control by selecting optimal communication methods for each service.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dispatcher-based priority control is used in the common bus method, then message priority control is implemented, but it is difficult to perform priority control on messages flowing through the common bus

Engineering Contradiction:

Improvemessage priority controlVSAvoidpriority control implementation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a message control unit as an intermediary component between the common bus and application units. This message control unit intercepts messages on the common bus, determines their priority based on message types, and controls their transmission accordingly. The intermediary enables priority control functionality that was previously difficult to implement in the common bus method.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter of message transmission control by introducing message type-based priority levels. Different message types are assigned different priorities, and the message control unit adjusts transmission parameters based on these priorities. This parameter change enables differentiated priority control for different services.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If internal application units transmit/receive messages by their respective unique methods, then message transmission is flexible, but message priority control becomes difficult

Engineering Contradiction:

Improvemessage transmission methodVSAvoidmessage priority control

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent creates a universal message control unit that handles multiple message types and services through a single standardized interface. This message control unit can manage messages from different application units using different unique methods, providing a unified priority control mechanism that works across diverse transmission methods.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The message control unit acts as a mediator that translates between various unique transmission methods of internal application units and a standardized priority control mechanism. It receives messages from different sources, determines their priority based on message types, and manages their transmission on the common bus.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple communication methods are supported for different services, then service-specific priority control is achieved, but system complexity increases

Engineering Contradiction:

Improvecommunication method selectionVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent manages complexity by changing parameters in a controlled manner - introducing message type parameters and priority level parameters. The message control unit uses these parameters to select appropriate communication methods without requiring complex decision logic. Each message type is associated with specific priority levels and communication method preferences.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent segments the message handling function into distinct components: message type identification, priority determination, and communication method selection. The message control unit processes messages in discrete steps based on message types, dividing the complex task of priority control into manageable segments that can be handled systematically.

Inventive Principle:

Principle #1Segmentation

AI summary

A message control program of an embodiment causes a monitoring apparatus to further function as a plurality of message control unit configured to individually controlling a communication method of a message transmitted from each internal application unit. Each message control unit receives a message containing a message type and service name from the internal application unit. Each message control unit specifies communication method identification information from a file based on the message type and service name in the received message. Each message control unit changes the communication method of the received message based on the specified communication method identification information, and sends the message to a common bus.
