Master Station Process Delegation Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for delegating processes do not ensure that a correct execution result is obtained at the delegation destination, leading to potential errors in process execution.
Innovation Solution
A master station device performs a verification test on a slave station device to confirm that a correct execution result can be obtained before delegating the process, using a verification test management unit and delegation decision unit to determine if the process should be executed by the slave station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a process is delegated to a slave station device without verification, then the delegation process is simple and fast, but the execution result may be incorrect
Solution Approach 1:
The patent applies preliminary action by performing verification tests on slave station devices before delegating processes to them. The master station device sends test data to the slave station, executes a verification process, and confirms whether the slave station can produce correct execution results. This preliminary verification ensures that only capable slave stations receive process delegations, thereby guaranteeing execution result correctness while maintaining a relatively simple delegation framework.
2Reliability
If a verification test is performed before delegation, then the execution result correctness is ensured, but the delegation process becomes more complex and time-consuming
Solution Approach 1:
The verification test is performed in advance before actual process delegation, so that the capability assessment of slave station devices is completed beforehand. This allows the master station to maintain a registry of verified slave stations and quickly delegate processes to suitable candidates without performing verification at the time of delegation, thus reducing the time loss during actual delegation operations.
Solution Approach 2:
The patent uses test data and verification processes as copies to assess slave station capabilities without requiring actual production data or processes. By using representative test cases, the system can evaluate slave station performance efficiently and make delegation decisions based on these copied scenarios, minimizing the impact on actual operational time.
3Productivity
If process delegation is performed without verification, then the system operation is efficient, but errors may occur in the delegation destination
Solution Approach 1:
The patent eliminates execution errors by performing preliminary verification tests that assess whether slave station devices can correctly execute delegated processes. The master station sends test data, executes verification processes on slave stations, and confirms capability before actual delegation. This preliminary action ensures that only verified, capable slave stations receive process delegations, maintaining high productivity while preventing execution errors.

AI summary
A delegation state management unit makes a gateway device perform a verification test to verify whether a correct execution result is obtained in a case wherein a process being a delegation candidate is delegated to the gateway device and the process is executed by the gateway device. Further, the delegation state management unit obtains a result of the verification test from the gateway device, and decides whether to delegate execution of the process to the gateway device, based on the result of the verification test obtained.
