Management Device for Operation Device Fault Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to seamlessly transition process operations from a failed working operation device to a standby operation device, especially when the standby device itself is faulty.
Innovation Solution
A management device with a node information storing unit, fault state acquiring unit, and instruction unit that monitors and manages the state of operation devices, sending work instructions to standby devices without faults to transition them into working state when the number of operational devices is below a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a standby operation device is selected without fault verification, then the system can quickly transition to a working state, but the standby device may itself be faulty causing system failure
Solution Approach 1:
The management device performs preliminary fault state acquisition for standby operation devices before selecting them for work transition. The fault state acquiring unit checks the standby device's health status in advance, ensuring that only devices without faults are selected, thus preventing system failure while maintaining quick transition capability
Solution Approach 2:
The system implements feedback mechanisms where the management device continuously monitors and acquires fault states from operation devices. This feedback loop ensures that the selection of standby devices is based on real-time health status information, balancing speed and reliability
2Reliability
If the management device monitors fault states of all standby devices, then reliable device selection is ensured, but the complexity of the management system increases
Solution Approach 1:
Standby operation devices autonomously report their own fault states to the management device through self-diagnosis functions. This self-service approach eliminates the need for complex external monitoring systems, as each device independently provides its health status information, simplifying the overall management architecture while maintaining reliable device selection
3Measurement precision
If the system waits for fault confirmation before transitioning, then accurate fault detection is achieved, but the response time to system failure increases
Solution Approach 1:
The management device performs preliminary fault state acquisition for standby devices before work transition is needed. By checking fault states in advance and maintaining updated information about device health, the system can immediately initiate transition when a working device fails, achieving both accurate fault detection and rapid response without waiting for confirmation

AI summary
A management device includes a node information storing unit which stores, for each of plural operation devices, an device state representing whether the operation device is in a working state or in a non-working state, the device state associated with an identifier of the operation device, a fault state acquiring unit which acquires a value representing whether or not a fault exists from each of the operation devices that are in the non-working state, and an instruction unit which sends, when a number of the operation devices is smaller than a predetermined value, a work instruction to the operation device from which the value representing that no fault exists is acquired and which is in the non-working state, among the plural operation devices which make a transition to the working state when receiving the work instruction while in the non-working state.
