Home Security Surveillance System Automatic Role Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home security surveillance systems face difficulties in easy installation and maintenance, particularly when universal detectors need to be designated as either master or slave, and when replacements are made, due to user unfamiliarity and complexity.
Innovation Solution
A home security surveillance system with detection terminals that can function selectively as master or slave, a computer-based server with enrollment records, and a gateway unit that automatically assigns and reassigns terminal roles, allowing for easy configuration and maintenance through a set button without requiring users to manually designate roles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If universal detectors are used that can operate selectively as master or slave, then manufacturing cost and design complexity are reduced, but installation and configuration become cumbersome for users
Solution Approach 1:
The system enables automatic role assignment where detectors self-configure as master or slave through a standardized initialization sequence. The first detector to initialize becomes the master automatically, eliminating the need for users to manually designate roles and reducing installation complexity while maintaining universal detector design
2Manufacturing precision
If manual designation of master and slave detectors is required, then system configuration precision is improved, but installation time and user complexity increase
Solution Approach 1:
The system performs preliminary automatic role assignment during the initialization phase before normal operation begins. Detectors automatically determine their master/slave roles through a predefined initialization sequence, ensuring proper system configuration without requiring time-consuming manual user intervention
3Reliability
If the master detector is replaced with a fresh detector, then system reliability is improved, but reestablishment of the in-house network becomes cumbersome
Solution Approach 1:
When a detector is replaced, the system automatically re-initializes and reassigns roles through the standardized initialization sequence. The new detector automatically becomes master or slave based on the initialization order, enabling seamless replacement without requiring users to manually reconfigure the network or remember previous role assignments

AI summary
A home security surveillance system has a plurality of terminal detectors one of which functions as a master, and the other function as a slave to constitute an in-house alarm network. The in-house network is linked to a server on the side of a service provider to transmit an aid-requesting signal through a gateway unit upon detection of a hazardous condition at each of the terminals. The detection terminal is provided with a configuration means and a set button which, upon being manipulated, activates the configuration means to send a configuration demand to the gateway unit and receive therefrom a configuration instruction by which the detection terminal is assigned as the master and the slave. The gateway unit is arranged to receive the configuration demand and read the master/slave index in its terminal status table so as to prepare the configuration instruction indicating whether such detection terminal is to be assigned as the master or slave.
