Information Equipment Network Breakdown Notification for HEMS Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for information equipment face security issues due to network breakdowns, where operational instructions may not be accurately received, leading to potential misoperation or failure in ensuring the security of the equipment.
Innovation Solution
Information equipment with a communication unit that transmits a breakdown notification message to the control apparatus upon network restoration, allowing for suspension of operations during breakdowns and retransmission of operational instructions to ensure secure and accurate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control of information equipment is implemented through a network, then ease of operation is improved, but reliability deteriorates due to network breakdowns causing loss of control accuracy
Solution Approach 1:
The information equipment proactively transmits a breakdown notification message to the control apparatus when detecting network restoration, before the control apparatus can retransmit commands. This preliminary notification allows the control apparatus to resume control operations accurately without relying on potentially lost previous instructions.
Solution Approach 2:
The system implements a feedback mechanism where the information equipment monitors network status and sends breakdown notification messages back to the control apparatus. This feedback loop ensures the control apparatus is aware of network interruptions and can adjust its control strategy accordingly, maintaining reliability despite remote operation.
2Adaptability or versatility
If operational instructions are transmitted via network, then adaptability is improved, but loss of information occurs when network breakdown prevents accurate receipt of instructions
Solution Approach 1:
The breakdown notification message serves as feedback information that allows the control apparatus to track the status of operational instructions. When the network is restored, the control apparatus can determine whether previous instructions were successfully received and retransmit only the necessary information, preventing loss of operational instruction accuracy.
Solution Approach 2:
By notifying the control apparatus of network restoration in advance, the system allows the control apparatus to prepare and retransmit operational instructions before the information equipment resumes normal operation, ensuring no instructional information is lost during the network interruption.

AI summary
An information equipment 300 located in a consumer's facility 300 includes a reception unit 310 and a transmission unit 320 that performs transmission and reception of a command conforming to a predetermined protocol with a HEMS 200 via a network connected to the HEMS 200, and receives an operational instruction from the HEMS 200 and a control unit 340 that controls an operation of the information equipment 300 according to the operational instruction. The transmission unit 320 transmits a breakdown notification message indicating that the network has had a breakdown to the HEMS 200 when the network is restored after the breakdown.
