Solution Overview
Problem
Current Internet-of-Things systems for intelligent gas meters have limited and insecure information circulation paths, making it difficult to effectively manage and control the operation of intelligent gas meters in a timely manner.
Innovation Solution
An Internet-of-Things system for intelligent gas meters is proposed, comprising an intelligent-gas-meter perception and control system, a gas network communication system, and a gas-company comprehensive gas management system, which establishes separate communication channels for perception and control information, forming a closed-loop system to enhance security and reliability, and includes a service system for public information acquisition and sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified communication channel is used for both perception and control information, then device complexity is reduced, but information security and reliability deteriorate due to increased tampering risk
Solution Approach 1:
The communication channel is segmented into two independent channels: a first communication channel for perception information (one-way from gas meter to server) and a second communication channel for control information (one-way from server to gas meter). This segmentation isolates the flow directions of different information types, preventing tampering in one channel from affecting the other, thereby improving security and reliability while maintaining manageable system complexity through clear functional separation.
2Reliability
If separate communication channels are established for perception and control information, then information security and reliability are improved, but device complexity increases
Solution Approach 1:
The system divides communication into two distinct one-way channels with clearly defined functions. The first channel handles perception information flow from the gas meter to the server, while the second channel handles control information flow from the server to the gas meter. This segmentation provides security through isolation while controlling complexity through standardized channel interfaces and protocols.
Solution Approach 2:
Instead of using a traditional two-way communication channel where the gas meter both sends and receives information, the system inverts the approach by implementing two separate one-way channels. This inversion ensures that the gas meter cannot receive unauthorized control commands through the perception channel, and the server cannot inject false data into the control channel, thereby enhancing security while maintaining clear channel management.
3Ease of manufacture
If traditional Internet-of-Things architecture is used, then ease of implementation is maintained, but information circulation paths become limited and insecure
Solution Approach 1:
The system applies segmentation to the communication architecture by establishing separate one-way channels for perception and control information. This approach enhances security by preventing cross-contamination of information flows while maintaining implementation feasibility through standardized communication protocols and modular system design that builds upon existing Internet-of-Things infrastructure.
Solution Approach 2:
The system inverts the traditional two-way communication model by implementing two independent one-way channels. This inversion fundamentally improves security by eliminating the possibility of unauthorized bidirectional communication, while the system remains implementable through conventional communication hardware and protocols adapted for unidirectional data flow.
