Service Vehicle Position Logging for Manual and GPS Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service vehicle control systems lack flexibility and efficiency, particularly in remote management, as they require GPS guidance for accurate operation, leading to inflexible usage and low-resolution data collection, which hampers operator flexibility and remote management capabilities.
Innovation Solution
A service vehicle system that allows for an operating mode where GPS positioning data is used for monitoring and reporting but not for guiding the vehicle or equipment, enabling high-resolution, location-dependent data collection even without GPS guidance, allowing operators to choose between GPS-guided and manual operations while maintaining remote data monitoring and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS guidance is used for service vehicle operation, then positioning accuracy and operational precision are improved, but operator flexibility and ease of manual operation deteriorate
Solution Approach 1:
The system dynamically switches between GPS-guided autonomous mode and manual control mode based on operational needs. The controller can operate in slave mode following GPS waypoints or in master mode under manual control, allowing the positioning system to adapt its level of automation according to the task requirements and operator preferences.
Solution Approach 2:
The system changes the operational parameter of GPS usage from mandatory guidance to optional monitoring. By modifying how GPS data is utilized (from control-critical to data-collection-only), the system maintains positioning accuracy for billing purposes while eliminating the constraint on operator flexibility during manual operations.
2Reliability
If GPS-guided autonomous operation is required for accurate service delivery, then service quality is improved, but device complexity and operational constraints increase
Solution Approach 1:
The system segments the GPS functionality into two independent components: guidance control (optional) and data collection (mandatory). This segmentation allows the monitoring and billing functions to operate independently of the control system, reducing overall system complexity while maintaining service quality through continuous position tracking for verification.
3Quantity of substance
If discrete per-job usage information is collected, then billing information is obtained, but management resolution and data precision deteriorate
Solution Approach 1:
The system implements continuous position monitoring and data logging throughout the entire service operation, rather than only at discrete job completion points. This continuous action captures detailed location information at regular intervals, enabling precise calculation of service metrics such as linear metres marked, area covered, or fluid application rates, thereby significantly improving billing resolution.
Data Source
AI summary
A service vehicle with service equipment for performing a predetermined service operation in an operating area, the vehicle comprising positioning means to determine position information for navigating the service vehicle and/or the service equipment; monitoring means to acquire position-dependent operational data of the performing of the service operation in dependence on the position information; and reporting means to communicate the position-dependent operational data to a remote management server. The service vehicle is operable in a first mode, in which the positioning means provides the position information to the monitoring means which acquires the position-dependent operational data using the position information; the reporting means communicates the operational data to the remote management server; and the navigating is performed substantially independently of the position information.
