Alert Management Apparatus Duplicate Notification Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems transmit multiple alert emails for the same device state issues, leading to increased network traffic and unnecessary maintenance server workload, as devices repeatedly send alerts for unsettled conditions upon powering on or recovering from a sleep state.
Innovation Solution
A management apparatus with a memory and control section that stores and checks alert information, notifying external systems only if the alert content is new, preventing duplicate notifications by comparing received alerts against stored records and deleting records when conditions are resolved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices transmit alert emails for every state change upon powering on or recovering from sleep state, then the device state monitoring is comprehensive, but network traffic increases and server workload increases due to duplicate notifications
Solution Approach 1:
The management apparatus performs preliminary actions by storing alert information in memory before transmission and checking for duplicates upon receiving new alerts. This preliminary checking mechanism prevents duplicate notifications from being transmitted to the external system, thereby reducing network traffic while maintaining complete device state monitoring.
Solution Approach 2:
The system implements a feedback mechanism where the management apparatus continuously monitors incoming alert information, compares it with stored records, and determines whether to transmit based on this feedback. The control section uses the feedback from the memory check to decide on transmission, eliminating redundant network communications while ensuring all actual state changes are reported.
2Reliability
If devices send multiple alert emails for unsettled conditions, then no alert is missed, but maintenance server workload increases due to processing duplicate alerts
Solution Approach 1:
The management apparatus performs preliminary filtering of alert information by checking against stored records in memory before forwarding to the external system. This preliminary action ensures that only unique, unresolved alerts are transmitted, maintaining complete notification of actual issues while preventing the maintenance server from processing duplicate alerts, thus improving server efficiency.
Solution Approach 2:
The management apparatus acts as an intermediary between the device and the external system. It receives alert information from the device, processes it by checking for duplicates against stored records, and then selectively transmits only unique alerts to the external system. This intermediary role protects the maintenance server from duplicate processing while ensuring all real alerts are communicated.
3Loss of information
If the management apparatus transmits all received alerts to external apparatus, then all device states are notified, but duplicate alerts increase communication overhead
Solution Approach 1:
The management apparatus performs preliminary processing of alert information by storing it in memory and checking for duplicates before transmission. This preliminary action filters out redundant data while preserving all unique device state information, thereby maintaining information completeness while reducing the volume of communication data to external systems.
Solution Approach 2:
The system uses feedback from comparing incoming alert information with stored records to determine transmission decisions. This feedback mechanism ensures that only new, unique alerts are transmitted, maintaining complete device state information communication while minimizing redundant data transmission and reducing overall communication overhead.

AI summary
A management apparatus according to the embodiment comprises a memory, an interface and a control section. If a device determined itself to be in a predefined first state, the interface receives the alert information transmitted from the device. The control section carries out no notice notifying the first state of the device to the external apparatus if a first information representing a state the same as the state represented by alert information is contained in the memory, and stores the first information in the memory based on the alert information and carries out the notice to an external apparatus if the first information is not contained in the memory.
