Controller Managing Waveform Analyzer Access Rights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems face challenges when multiple apparatuses are accessible to multiple waveform analyzers, leading to conflicting operations and excessive communication data flow, which can exceed communication capacity.
Innovation Solution
An information processing method and apparatus that manages control rights among operation terminals, allowing only one terminal to operate waveform analyzers and prioritizing communication bandwidth for high-priority analyzers, thereby preventing conflicts and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation terminals can access and operate waveform analyzers simultaneously, then the system's adaptability and ease of operation are improved, but conflicting operations occur and system reliability deteriorates
Solution Approach 1:
The patent introduces a controller as an intermediary between multiple operation terminals and waveform analyzers. The controller manages control rights by receiving operation requests from terminals, determining whether to grant control based on current state, and mediating access to prevent conflicts. This intermediary layer enables multiple terminals to access analyzers safely without direct peer-to-peer conflicts.
2Ease of operation
If control rights are granted to multiple operation terminals simultaneously, then ease of operation is improved, but harmful factors increase due to conflicting operations
Solution Approach 1:
The patent implements preliminary action by requiring operation terminals to send control right acquisition requests before actually operating the waveform analyzers. The controller evaluates these requests in advance, checks current control state, and grants or denies control rights beforehand. This preliminary control mechanism prevents conflicting operations from occurring in the first place.
3Productivity
If all waveform analyzers transmit measurement data simultaneously, then productivity and information availability are improved, but communication bandwidth is exceeded causing data loss
Solution Approach 1:
The patent implements periodic action by having the controller transmit measurement data from waveform analyzers to operation terminals in periodic cycles rather than continuously or simultaneously. The controller manages transmission timing, selecting which analyzers' data to transmit in each cycle based on priorities and current states. This periodic transmission pattern prevents communication bandwidth overflow while maintaining data availability.
Data Source
AI summary
An information processing method includes receiving, by the controller via a communication interface, screen information regarding measurement information on a physical quantity from one or more waveform analyzers that acquire the measurement information, transmitting, by the controller via the communication interface, the acquired screen information to a plurality of operation terminals, receiving, from a first operation terminal of the plurality of operation terminals, a request for operation on the one or more waveform analyzers through the screen information, determining, by the controller, whether a control right to operate the one or more waveform analyzers is granted to any operation terminal of the plurality of operation terminals except the first operation terminal, and granting, by the controller, the control right to the first operation terminal in response to determining that the control right is not granted to any operation terminal of the plurality of operation terminals except the first operation terminal.
