Long-Thin Fleet Positioning via Leading Member GPS Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Global positioning systems (GPS) in mobile devices consume excessive power, limiting their operational time, especially in fleets like bike fleets where additional charging equipment is often unavailable, making continuous GPS usage inconvenient.
Innovation Solution
A positioning method for long-thin fleets that utilizes a leading member to acquire and transmit periodic positioning data via a Wi-Fi wireless Ad Hoc network, allowing other members to calculate their positions without activating their GPS, thereby reducing power consumption and extending operational time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is turned on for a long time in mobile devices, then positioning accuracy is maintained, but power consumption increases excessively
Solution Approach 1:
The fleet is divided into a leading member and following members. The leading member uses GPS for accurate positioning, while following members use wireless communication to receive positioning data, segmenting the GPS usage requirement across the fleet to reduce overall power consumption.
Solution Approach 2:
Positioning data is transmitted wirelessly from the leading member to following members through a communication network, acting as an intermediary to transfer positioning information without requiring GPS receivers in all devices, thus reducing power consumption while maintaining positioning accuracy.
2Duration of action of moving object
If additional power charging equipment is provided for continuous GPS operation, then operational time is extended, but device complexity and cost increase
Solution Approach 1:
The system uses existing wireless communication capabilities and battery power of mobile devices to transmit and receive positioning data, allowing the fleet to maintain operational capability without external charging equipment or additional power infrastructure.
Solution Approach 2:
Mobile devices in the fleet perform multiple functions: they serve as both communication devices for receiving positioning data and as positioning units when needed. This multi-functionality eliminates the need for dedicated charging equipment or separate positioning hardware.
3Measurement precision
If GPS is used in all fleet members, then positioning precision is maintained, but the number of devices to be charged increases
Solution Approach 1:
The positioning function is segmented so that only the leading member requires GPS capability. Following members rely on wireless communication to obtain positioning information, reducing the total number of GPS receivers needed in the fleet while maintaining overall positioning precision.
Solution Approach 2:
Positioning information is transmitted through wireless communication networks as an intermediary, allowing following members to obtain accurate positioning data without having their own GPS receivers, thus reducing the quantity of GPS devices required.

AI summary
The present invention provides a positioning method for long-thin fleet, which moves along a direction and has a motion track and a leading member. The leading member is in forefront of the motion track. The positioning method comprises the following steps: a positioning step and a transmitting step. The positioning step gets a positioning data through a GPS in a preset time. The transmitting step transmits a periodic signal to the members of the fleet through a wireless network system. The leading member proceeds the positioning and transmitting steps. The motion track is connected according to the positioning data.
