Car Status Data Transmission via VNC and UPnP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for image display apparatuses in cars lack efficient methods for transmitting and receiving car status information between devices, such as speed, driving mode, and fuel quantity, which limits seamless data sharing and user control.
Innovation Solution
Implementing a data processing system that uses Virtual Network Computing (VNC) and Universal Plug and Play (UPnP) services to enable efficient transmission of car status information between a mobile terminal and an image display apparatus, allowing for remote control and real-time data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If car status information is transmitted between devices using traditional methods, then data sharing is achieved, but transmission efficiency and real-time performance are insufficient
Solution Approach 1:
The patent segments car status information into different types (basic status, detailed status, alarm information) and transmits them through different data processing paths. Basic status information is transmitted continuously at high speed, while detailed information is transmitted on-demand, optimizing overall transmission efficiency and reducing delays.
Solution Approach 2:
The system implements periodic transmission of car status information at optimized intervals based on the type of information and current driving conditions. This periodic action ensures real-time data sharing while avoiding unnecessary continuous transmission that would waste bandwidth and increase processing delays.
2Loss of information
If comprehensive car status information is transmitted between devices, then data completeness is improved, but data transmission complexity increases
Solution Approach 1:
The patent applies different quality levels of data transmission to different types of car status information. Critical safety-related information is transmitted with highest priority and completeness, while non-critical information uses optimized lower-bandwidth formats. This local quality differentiation ensures information completeness where needed while reducing overall processing complexity.
Solution Approach 2:
The system transmits only the necessary portion of car status information based on current needs - basic status information is transmitted continuously, while detailed information is transmitted partially only when requested or when changes occur. This partial action approach maintains information completeness for critical data while reducing processing complexity for non-critical data.
3Adaptability or versatility
If multiple devices share car status information, then user control capability is enhanced, but system integration complexity increases
Solution Approach 1:
The patent implements a universal data transmission protocol that enables multiple devices (mobile terminals, in-car display systems, external servers) to share car status information through a common interface. This universality allows different devices to perform multiple functions - serving as both information sources and recipients - thereby enhancing user control capability without proportionally increasing system integration complexity.
