Wireless Tag Positioning via Mobile Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking and positioning systems for pets and valuables are inadequate as they often rely on locks and do not provide real-time location information, making it difficult for owners to retrieve lost pets or items.
Innovation Solution
A wireless tracking and positioning system comprising a wireless tag with a WIFI or Bluetooth chip, a mobile terminal, and a server cloud platform that allows for real-time tracking and positioning of a tracked object without the need for pre-arranged devices or password verification, using a mobile or wireless network to relay and store position information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a wireless tracking system is implemented for pets and valuables, then real-time position information can be obtained, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple functions into the mobile terminal device: it acts as both the tracker (detecting wireless tags) and the relay station (communicating with server). This merging eliminates the need for separate dedicated tracking devices, reducing overall system complexity while enabling real-time position information acquisition.
Solution Approach 2:
The mobile terminal is designed to perform multiple roles: it functions as a wireless tag detector, a relay communication node, and a user interface device. This multi-functionality allows the system to achieve real-time tracking without requiring specialized equipment, thereby reducing device complexity and cost.
2Reliability
If conventional tracking systems with pre-arranged devices are used, then tracking reliability is improved, but cost and ease of operation deteriorate
Solution Approach 1:
The system enables ordinary mobile terminals (smartphones, tablets) to automatically function as relay stations without requiring pre-arranged specialized devices. Users simply need to have a smartphone with the application, eliminating the need for separate tracking equipment and simplifying operation while maintaining reliability through the distributed relay network.
Solution Approach 2:
By designing the system to work with universal mobile terminals that everyone already possesses, the patent eliminates the need for specialized pre-arranged devices. The mobile terminal's existing capabilities are leveraged for tracking purposes, making the system easy to operate while maintaining reliable tracking functionality.
3Measurement precision
If continuous broadcasting of ID information is implemented, then position information accuracy is improved, but power consumption increases
Solution Approach 1:
The wireless tag broadcasts ID information periodically rather than continuously. This periodic broadcasting reduces power consumption significantly while still providing sufficient position information accuracy, as the mobile terminal detects the tag at regular intervals and updates the position accordingly.
Solution Approach 2:
The mobile terminal acts as an intermediary that accumulates position information from periodic broadcasts and then transmits comprehensive position data to the server. This approach allows the low-power periodic broadcasting to achieve the same tracking accuracy as continuous transmission would provide, by leveraging the mobile terminal's processing and relay capabilities.

AI summary
A wireless tracking and positioning system includes: a wireless tag, a mobile terminal and a server cloud platform. A wireless tracking and positioning method includes steps of: placing a wireless tag on a tracked object for continuously or intermittently broadcasting ID information; receiving the ID information with a mobile terminal which sends self position information and the ID information of the wireless tag to a server cloud platform; storing information of the tracked object in the server cloud platform; when the tracked object moves, timely updating and storing the position information of the wireless tag, and displaying the position information on the server cloud platform; when a user requires the position information of the tracked object, accessing the server cloud platform through an interface reserved by the server cloud platform, and obtaining the position information and ID information of the tracked object.
