Intercom Network Slot Sharing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intercom systems face challenges in maintaining high-quality image transmission due to noise and signal distortion, especially when multiple communication networks are connected, leading to inefficient use of communication resources and decreased quality.
Innovation Solution
An intercom system with a first and second communication network, where at least one intercom master device controls the sharing or unsharing of information between networks on a per-time-slot basis, allowing for connection or disconnection based on settings, optimizing resource use and communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple communication networks are connected to share information between households, then convenience is improved, but communication resources are unnecessarily consumed and communication quality deteriorates
Solution Approach 1:
The communication network is segmented into multiple communication networks, each corresponding to a different household. Each communication network operates independently with its own time slots, allowing selective sharing of information between networks while maintaining resource efficiency. The intercom master device controls which time slots are shared between networks, preventing unnecessary resource consumption while enabling convenient cross-household communication when needed.
2Ease of operation
If multiple communication networks are connected to share information between households, then convenience is improved, but communication quality deteriorates
Solution Approach 1:
The communication network is segmented into multiple independent communication networks, each with dedicated time slots. This segmentation prevents interference between networks while allowing selective sharing of specific time slots when convenience is needed, thereby maintaining communication quality through controlled resource allocation rather than unrestricted network merging.
3Loss of information
If image data is transmitted across connected communication networks, then information sharing is improved, but communication resources are consumed
Solution Approach 1:
Different time slots are assigned different sharing characteristics based on local requirements. Some time slots are configured for shared communication between households, while others remain dedicated to individual households. This local quality approach allows image data and other information to be shared only when and where needed, optimizing the balance between information sharing and resource consumption.

AI summary
An intercom system includes first and second communication networks, a network connector (cable connector, reception driver, and transmission driver), an operation setter, and a connection controller. Each of the first and second communication networks includes an entrance slave device and an intercom master device, and performs communication by time division duplex. The network connector is used for connecting the communication networks. The operation setter sets share or unshare in order to indicate whether or not information stored in a slot is shared between the first communication network and the second communication network, for each slot. The connection controller controls the network connector to perform connection or disconnection (operation of transmission driver) between the first communication network and the second communication network, in accordance with settings of the share or the unshare.
