Monitoring System Controller Complexity Reduction via Mobile Phone Signal Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing monitoring systems that enable data input and output between a mobile phone terminal and a camera are costly due to complex configurations, making it difficult to implement them at a low cost without compromising user convenience.
Innovation Solution
A monitoring system that utilizes an existing fixed telephone connected to a fixed telephone network for calls and includes a monitoring camera with a microphone, speaker, and image capturing unit, along with a master device for wireless communication with a mobile phone terminal via a wireless router, allowing for low-cost data input and output between the camera and mobile phone terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a video signal and audio signal switching configuration is implemented in the controller to capture intruders, then the monitoring capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the signal switching function from the controller and relocates it to the mobile phone terminal. The controller simply transmits captured video and audio signals to the mobile phone, while the mobile phone handles the switching and display functions. This separation reduces the controller's complexity while maintaining monitoring capability.
Solution Approach 2:
The mobile phone terminal serves multiple functions: it receives video/audio signals from the controller, switches between different camera feeds, displays the selected signals, and provides user interface operations. This multi-functionality eliminates the need for a complex dedicated controller while maintaining comprehensive monitoring capabilities.
2Reliability
If a complex controller configuration is used to switch and transmit video and audio signals, then the monitoring function is enhanced, but the system cost increases
Solution Approach 1:
The patent removes the complex signal switching and processing functions from the controller and transfers them to the mobile phone terminal. The controller becomes a simple signal transmission device, significantly reducing manufacturing complexity and cost while the mobile phone handles all sophisticated signal management tasks.
Solution Approach 2:
The mobile phone terminal performs self-service by handling its own signal switching, display, and user interaction functions. This eliminates the need for an expensive specialized controller, as the mobile phone's existing processing capabilities are utilized to manage the monitoring system's signal requirements.
3Ease of manufacture
If an existing fixed telephone is used for calls instead of a complex controller, then the cost is reduced, but the data input and output capability between mobile phone and camera must be maintained
Solution Approach 1:
The mobile phone terminal serves as a universal device that combines multiple functions: it acts as the user interface for selecting audio sources, processes video and audio signals from the camera, handles wireless communication with the master device, and provides display output. This multi-functionality maintains comprehensive data input and output capabilities while using a simple, cost-effective fixed telephone for voice calls.
Data Source
AI summary
In a monitoring system, a master device transmits predetermined sound source list data to a mobile phone terminal in response to a first operation on a display/input unit. The mobile phone terminal displays the predetermined sound source list data transmitted from the master device on the display/input unit, and transmits information regarding a selected sound source to the master device in response to an operation of selecting one sound source from the sound source list data. When the information regarding the sound source is received from the mobile phone terminal, the master device outputs selection audio data corresponding to the information regarding the selected sound source from a speaker of a monitoring camera.
