Problem
Conventional network-based facility device management systems face high security risks and increased costs due to the need for extensive configuration and security standard compliance when setting up new devices, requiring specialized knowledge and time.
Innovation Solution
A control system that includes a facility-device management apparatus and a relay device, allowing for secure data transmission to a remote monitoring server using different protocols, enabling easy configuration and reducing exposure to external threats by indirect network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If facility devices are directly connected to the network for monitoring, then data transmission capability is improved, but security risk increases
Solution Approach 1:
The patent introduces a gateway device as an intermediary between facility devices and the network. The gateway performs protocol conversion between the first protocol used by facility devices and the second protocol used by the network, enabling data transmission while isolating facility devices from direct network exposure and reducing security risks
2Reliability
If security restrictions are imposed on the network, then security is improved, but device complexity increases
Solution Approach 1:
The gateway device automatically performs protocol conversion and security management functions without requiring manual configuration of security settings on individual facility devices. This self-service approach maintains security while reducing the configuration burden on users
3Reliability
If protocol conversion is implemented through a relay device, then security is improved, but transmission delay increases
Solution Approach 1:
The gateway device maintains protocol conversion rules and conversion logic in advance, allowing it to perform protocol conversion operations quickly without requiring complex real-time processing or multiple intermediary steps, thus minimizing transmission delay while maintaining security
Data Source
AI summary
A control system transmits, to a remote monitoring server, report data generated based on operation data. The control system includes a facility-device management apparatus that generates report data based on the operation data, and a relay device that communicates with the remote monitoring server via an intra-facility LAN and communicates with the facility-device management apparatus via a connection line. The facility-device management apparatus includes setting means for setting whether or not the report data is to be transmitted to the remote monitoring server, first transmission means for transmitting the report data to the remote monitoring server, and second transmission means for transmitting the report data to the relay device. The relay device includes forwarding means for transmitting, to the intra-facility LAN, the report data received from the facility-device management apparatus.
