Equipment item device, management device, equipment item management system, communication control method between equipment and management device
Solution Overview
Problem
In equipment apparatus management systems, unregistered devices generate unnecessary network traffic by continuously retrying notifications to the management center, leading to increased network usage and inefficiency.
Innovation Solution
A management apparatus with a notification receiver section, storage section, registration determiner section, notification prevention command creator section, and command transmitter section is implemented to identify unregistered devices and send notification prevention commands, preventing unnecessary notifications and reducing network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the management center sends response notifications to unregistered equipment apparatuses, then the equipment apparatuses can retry notifications, but unnecessary network traffic is generated
Solution Approach 1:
The management center performs preliminary identification of unregistered equipment apparatuses before processing notifications. By checking registration status in advance and sending prevention commands to unregistered devices, the system prevents unnecessary notification retry cycles, thereby reducing network traffic while maintaining reliable notification delivery for registered devices
2Productivity
If unregistered equipment apparatuses continuously retry notifications, then they can eventually transmit device information, but network load increases
Solution Approach 1:
The system extracts and separates unregistered equipment apparatuses from the normal notification processing flow. By identifying unregistered devices and sending them specific prevention commands, the system removes them from the retry cycle, allowing registered devices to maintain normal notification productivity while preventing network bandwidth consumption from unregistered devices

AI summary
A management apparatus (10), configured to manage plural equipment apparatuses (40) through a network, includes a notification receiver section (11), a storage section (12), a registration determiner section (13), a notification prevention command creator section (14), and a command transmitter section (19). The notification receiver section (11) is configured to receive a notification from each of the equipment apparatuses. The storage section (12) is configured to store plural sets of identification information of the respective equipment apparatuses and plural sets of registration information of the respective equipment apparatuses for indicating a registered/unregistered status of each of the equipment apparatuses. The registration determiner section (13) is configured to determine the registered/unregistered status of each of the equipment apparatuses with reference to a corresponding set of the identification information and a corresponding set of the registration information when the notification receiver section (11) receives the notification. The notification prevention command creator section (14) is configured to create a notification prevention command when each of the equipment apparatuses (40) is determined to have the unregistered status. The command transmitter (19) is configured to transmit the notification prevention command to each of the equipment apparatuses.
