Remote Operation Exclusive Control for Multi-Terminal Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple supporting person-serving terminals perform remote operations on a single supported person-serving terminal simultaneously, it often leads to erroneous operations, increasing the burden on the user of the supporting terminal due to the need for repeated remote operations.
Innovation Solution
The system determines whether a remote operation is being performed exclusively by another terminal and, if not, allows the supporting person-serving terminal to initiate a remote operation by acquiring and displaying the display information of the supported terminal, and transmitting operation information to ensure exclusive control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple supporting terminals perform remote operations on a single supported terminal simultaneously, then the versatility and collaborative capability are improved, but the reliability and operational accuracy deteriorate due to erroneous operations
Solution Approach 1:
The system preemptively prevents conflicting remote operations by implementing an exclusive control mechanism. Before allowing a remote operation to proceed, the system checks whether another supporting terminal is already controlling the supported terminal. If so, the new operation request is blocked, thereby preventing erroneous operations that would arise from simultaneous control attempts.
Solution Approach 2:
The system implements a feedback mechanism where the supported terminal continuously reports its current control state to supporting terminals. This feedback loop allows the system to detect whether a remote operation is already in progress and adjust subsequent operation requests accordingly, ensuring that only one supporting terminal can actively control the supported terminal at any given time.
2Adaptability or versatility
If multiple supporting terminals can connect to one supported terminal, then the adaptability is improved, but the operational complexity and error rate increase
Solution Approach 1:
The system performs preliminary actions by establishing clear control ownership before remote operations begin. The first supporting terminal to connect is granted exclusive control rights, and this ownership is maintained until the operation completes or is explicitly released. This preliminary establishment of control hierarchy simplifies subsequent coordination by eliminating the need for complex real-time arbitration among multiple terminals.
3Reliability
If exclusive control checking is implemented, then the reliability is improved, but the operation time and response delay increase
Solution Approach 1:
The system performs the exclusive control check in advance, during the connection establishment phase, rather than during active operation. By determining control ownership upfront and caching this information, the system avoids repeated checking during actual remote operations, thereby minimizing time loss while maintaining reliability.

AI summary
A remote operation method executed by a computer. The remote operation method includes, acquiring a first display information that is displayed on a first display of a terminal, displaying a second display information on a second display of the computer based on the first display information, the second display information including the first display information, determining whether a first remote operation of the terminal is under execution by another computer, the other computer displaying a third display information on a third display of the other computer, the third display information including the first display information, and performing a second remote operation of the terminal when it is determined that the first remote operation is not under execution by the other computer.
