Facility Device Control-Program Updates Using Cloud Version Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facility device management systems require user intervention for software updates, leading to inefficiencies and potential delays in updating programs, which can compromise user comfort and security.
Innovation Solution
A management apparatus that automatically determines the necessity of control program updates for facility devices by comparing local versions with server versions and downloads the necessary updates at predetermined times, eliminating the need for user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If automatic update determination is implemented, then update timeliness is improved, but system complexity increases
Solution Approach 1:
The management apparatus automatically determines update necessity by comparing version information without requiring user initiation. The system performs self-service update management by autonomously checking versions, determining update needs, and executing downloads, thereby eliminating time delays while managing complexity through automated workflows.
Solution Approach 2:
The system performs version comparison and update determination in advance before user requests are needed. By proactively checking for updates and determining their necessity beforehand, the system ensures timely updates while preparing the update mechanism in advance to handle the increased complexity systematically.
2Ease of operation
If user operation is eliminated for updates, then ease of operation is improved, but reliability may worsen due to automated errors
Solution Approach 1:
The management apparatus implements feedback mechanisms where version information is continuously compared between local facility devices and the server. The system receives feedback about version discrepancies and automatically adjusts its update determination based on this feedback, ensuring reliable automated operation while maintaining ease of use by eliminating manual intervention.
Solution Approach 2:
The system performs self-service update management with automated version comparison and update determination. By eliminating user operation entirely from the update process, the system improves ease of operation while maintaining reliability through automated error-checking and server-validated update protocols that prevent erroneous updates.
3Productivity
If version comparison is performed automatically, then productivity is improved, but loss of information increases due to network dependencies
Solution Approach 1:
The management apparatus performs preliminary version information acquisition by comparing local versions with server versions before update execution. By proactively gathering and comparing version information in advance, the system improves productivity through automated update management while mitigating information loss risks by ensuring version data is obtained and validated before network dependencies become critical.
Solution Approach 2:
The system implements feedback loops where version information is continuously exchanged between the management apparatus and server. This feedback mechanism ensures that version information is maintained and synchronized, improving productivity through automated comparison while preventing information loss by continuously validating version data through network feedback channels.
Data Source
AI summary
In a facility management system, a management apparatus stores a version of a control program stored in each of one or more facility devices. In response to arrival of a predetermined timing, for each of the one or more facility devices, the management apparatus determines whether or not it is necessary to update a control program, by comparing a version of a control program stored in the management apparatus with a version specified by version information of a control program stored in a cloud server. Then, the management apparatus downloads the control program from the cloud server for a facility device for which it has been determined that it is necessary to update the control program.
