Engineering Contradiction Analysis
1Reliability
If manual configuration of LAN structure is performed, then the zone control system can be established, but significant time and effort are required especially in buildings with multiple zones
Solution Approach 1:
The zone controller automatically performs LAN structure configuration by calculating correlation degrees with apparatus control nodes and sensors, selecting the highest correlation degree connections, and establishing the network topology without human intervention. This self-service mechanism eliminates manual mapping and connection tasks.
Solution Approach 2:
The system uses correlation degree as a parameter to automatically determine connection relationships. By calculating and comparing correlation degree values between the zone controller and other devices, the system dynamically selects optimal connections based on the highest correlation degree, replacing static manual configuration.
2Ease of operation
If manual mapping table configuration is performed, then the LAN structure can be configured, but installation personnel must spend significant time on statistics and calculation
Solution Approach 1:
The patent replaces the mechanical process of manual mapping table creation with an automated electronic calculation system. The zone controller automatically calculates correlation degrees using electronic algorithms, substituting the manual statistics and calculation work performed by installation personnel.
Solution Approach 2:
The correlation degree calculation serves as an intermediary mechanism that automatically determines connection relationships. Instead of manually creating mapping tables, the system uses correlation degree as an intermediate parameter to automatically establish the LAN structure configuration.
3Adaptability or versatility
If the number of zones in the building is much greater, then the building can be comprehensively controlled, but the configuration time increases significantly
Solution Approach 1:
The patent divides the large-scale building control into independent zone segments. Each zone controller autonomously configures its own LAN structure by calculating correlation degrees locally, eliminating the need for centralized manual configuration of the entire building. This segmentation allows parallel configuration across multiple zones.
Solution Approach 2:
The zone controller performs preliminary automatic configuration actions before the building is fully operational. By pre-calculating correlation degrees and establishing LAN structures automatically during installation, the system eliminates the need for time-consuming manual configuration that would otherwise be required for each zone.

AI summary
A zone control system includes a zone controller (ZC), an apparatus control node, and a sensor. The ZC includes a LAN structure template which records a network topology in a zone where the ZC is installed. The ZC executes calculations of correlation degree for adjacent apparatus control nodes and sensors, automatically connects to the highest correlation degree of the apparatus control nodes, and controls the connected apparatus control nodes to connect to the highest correlation degree of the sensors according to the calculation results and the LAN structure template. Accordingly, the ZC can automatically configure the LAN structure in the zone where the ZC is installed and establish a zone control system in the zone.
