Network GPS Terminal for Multi-Device Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPS systems are inefficient as each device in a vehicle typically has its own GPS receiver, leading to resource waste and clutter, as they are designed to work closely with specific application programs and communicate through serial connections, making it difficult to share GPS data across multiple devices.
Innovation Solution
A network-based GPS terminal that includes a GPS receiver, processor, network communication module, security access controller, and network management part, using TCP/IP protocol to process and transmit GPS data to external devices, allowing simultaneous access and management of connections and security information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each device in a vehicle is equipped with its own GPS receiver, then each device can independently receive GPS data, but this results in resource waste and clutter inside the vehicle
Solution Approach 1:
The patent consolidates multiple GPS receivers into a single centralized GPS receiver that serves all devices in the vehicle. This merging approach eliminates redundant hardware while maintaining reliable GPS data supply to all connected devices through the vehicle's internal network
Solution Approach 2:
The single GPS receiver is designed to serve multiple functions and multiple devices simultaneously. It can provide GPS data to various types of external devices (navigation systems, mobile phones, tablets, etc.) through network communication, making the receiver universal rather than device-specific
2Adaptability or versatility
If each device has its own GPS receiver, then each device can process GPS data independently, but this leads to device complexity and difficulty in sharing GPS data across multiple devices
Solution Approach 1:
The patent introduces a network communication module as an intermediary between the GPS receiver and multiple external devices. This mediator handles data distribution, protocol conversion, and device management, simplifying the system architecture while enabling seamless GPS data sharing across diverse devices
Solution Approach 2:
The system separates the GPS signal reception and processing functions from the application devices. The GPS receiver and network communication module form a dedicated subsystem that handles all GPS-related operations, while external devices only need network connectivity to access GPS data, dividing complexity into manageable segments
3Adaptability or versatility
If GPS receivers are designed to work closely with specific application programs through serial communication, then they can provide dedicated functionality, but this makes it difficult to separate the GPS receiver from the program and share data across multiple applications
Solution Approach 1:
The patent changes the communication parameter from proprietary serial communication to standard network protocols (TCP/IP). This parameter change enables the GPS receiver to communicate with multiple types of devices simultaneously through the vehicle's network infrastructure, improving compatibility while the network management module handles connection coordination

AI summary
Provided is a network global positioning system (GPS) terminal. The network GPS terminal includes: a GPS receiver receiving GPS data; a GPS processor processing the received GPS data to a predetermined form; a network communication part communicating with an external apparatus through a network in order to receive a request for the GPS data from the external apparatus, and transmit the processed GPS data to the external apparatus in response to the request; a security access controller authenticating the external apparatus; and a network management part managing connection information and security information of the external apparatus, the network communication part simultaneously communicating with at least one external apparatus using a TCP/IP protocol. A method of providing GPS data using a network is also provided.
