Building Controller Virtual Terminal Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional residential room master devices designed for centralized intercom systems cannot be used in distributed intercom systems due to incompatibility with building controllers designed for distributed systems, leading to increased costs and product diversity.
Innovation Solution
The intercom system includes residential room master devices, terminal devices, and a building controller that uses identification information to recognize and communicate with each other, allowing the residential room master device to function in both centralized and distributed systems by converting signals between intercom lines and networks, and recognizing the building controller as a virtual terminal device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional residential room master device designed for centralized intercom systems is used, then the device can be used in centralized systems, but it cannot be used in distributed intercom systems due to incompatibility with building controllers
Solution Approach 1:
The building controller acts as an intermediary device that mediates communication between the centralized building controller and the residential room master device. It translates and forwards call signals between these two incompatible systems, enabling the room master device to function in both centralized and distributed intercom system architectures without modification.
2Power
If building controllers are distributed among residential buildings in a distributed intercom system, then the processing power requirement of the centralized controller is reduced, but conventional residential room master devices cannot recognize the distributed building controllers
Solution Approach 1:
The building controller is designed with multi-functionality to operate in both centralized and distributed intercom system architectures. It can function as a distributed building controller in residential buildings while simultaneously acting as a virtual terminal device that conventional room master devices can recognize and communicate with, thus achieving universal compatibility across different system types.
3Quantity of substance
If the number of residential buildings is increased in a centralized intercom system, then the system coverage is expanded, but the processing power of the centralized controller must be enhanced and cost increases
Solution Approach 1:
The centralized intercom system is segmented into multiple distributed building controllers, each responsible for processing call signals within its own residential building. This segmentation distributes the processing power requirements across multiple independent units, allowing the system to expand to cover more residential buildings without requiring a single centralized controller to handle all processing demands, thus controlling costs.

AI summary
An interphone system for use in collective housing constituted by a plurality of residential buildings and a centralization building (5) capable of communicating with each residential building, each of the residential buildings comprising: a residential-unit master device (30) installed in each residential unit; a plurality of collective entrance devices (10A-10D) capable of communicating with the residential-unit master device (30); and a building controller communicatively connecting the residential-unit master device (30) in each residential unit with the collective entrance devices (10A-10D) in the building, wherein the building controller has: a building controller ID that, at the time of calling up the residential-unit master device (30) from the centralization building (5) via the building controller, is used for the centralization building (5) to identify the building controller; and a collective entrance device ID that, at the time of calling up the residential-unit master device (30) from the centralization building (5) via the building controller, is used for the residential-unit master device (30) to identify the building controller as a virtual collective entrance device different from the collective entrance devices (10A-10D).
