Mobile Geo-Location Perimeter Switching for Low-Power Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geographical location systems for mobile apparatuses, such as cleaning machines, consume excessive communication resources and power, and incur high charges due to constant online communication, which is unnecessary for most situations.
Innovation Solution
A system that defines an offline perimeter around the mobile apparatus, only establishing communication with a central location when the apparatus moves outside this perimeter, and then sets up a larger online perimeter for tracking, reducing unnecessary communication and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant online communication is used to track the mobile apparatus, then the location monitoring reliability is improved, but the power consumption increases and communication resources are wasted
Solution Approach 1:
The system transitions from constant online communication to periodic communication triggered only by specific events (perimeter breaches). The mobile apparatus communicates with the central location system only when it detects that it has moved outside the offline perimeter, thereby reducing power consumption while maintaining monitoring reliability through event-driven updates.
Solution Approach 2:
The system dynamically adjusts its communication state between offline and online modes based on the apparatus's location relative to the perimeter. When inside the perimeter, the apparatus operates offline with minimal power consumption; when outside, it automatically establishes online communication, optimizing the balance between reliability and energy usage.
2Measurement precision
If constant online communication is used to track the mobile apparatus, then the location monitoring accuracy is improved, but the communication resource consumption increases
Solution Approach 1:
The system uses event-triggered periodic communication rather than continuous communication. Location monitoring accuracy is maintained by establishing online communication precisely when the apparatus breaches the perimeter, ensuring accurate tracking at critical moments while minimizing overall communication resource consumption.
Solution Approach 2:
The system extracts and isolates the communication function to only when necessary (perimeter breach events). By separating the offline local monitoring from online remote communication, the system achieves accurate location monitoring through the offline perimeter detection while eliminating unnecessary communication resource consumption during normal operation within the perimeter.
3Area of stationary object
If constant online communication is used to track the mobile apparatus, then the monitoring coverage is improved, but the operational costs increase
Solution Approach 1:
The system implements event-driven periodic communication that maintains comprehensive monitoring coverage through the offline perimeter definition while incurring operational costs only when the apparatus breaches the perimeter. This approach ensures full monitoring coverage is available (through the offline perimeter detection capability) but actual communication costs are incurred only when necessary.
Solution Approach 2:
The offline perimeter is pre-defined and stored locally in the mobile apparatus, enabling immediate local detection of breaches without requiring continuous online communication. This preliminary setup maintains comprehensive monitoring coverage while eliminating ongoing operational communication costs, charging fees only when the pre-defined perimeter is breached.

AI summary
A system and method are provided for determining a location of a mobile apparatus. The mobile apparatus can include a chassis, a communications module, and a controller including a processor and memory, wherein the processor is programmed to perform instructions that are stored in the memory. The instructions can include defining an offline perimeter surrounding the chassis, locating a chassis position in relation to the offline perimeter, and determining whether the chassis position is outside the offline perimeter. Upon making this determination, the processor is programmed to establish communication between the mobile apparatus and the central location via the communication module, receive an indication from a network that the chassis is located outside an online perimeter that is larger than the offline perimeter, and output a signal upon receiving the indication.
