Lawn Mower Management System Drive Control Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems for work machines like lawn mowers lack sufficient information for effective management, as they only track whether the engine is running, failing to capture essential operational data needed for comprehensive management.
Innovation Solution
A management system comprising an electronic controller and a communicator at the lawn mower that transmits drive control information and behavior history to a server via a network, enabling real-time data acquisition and processing for user and dealer terminals, facilitating maintenance and operational insights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only engine running status is tracked, then system complexity is reduced, but information sufficiency for management deteriorates
Solution Approach 1:
The system segments management information into multiple categories (drive control information, behavior history information, abnormality determination results) and collects them from different sources (electronic controller, sensors, user inputs) to achieve comprehensive management without overwhelming complexity
Solution Approach 2:
The system transitions from single-dimensional engine status tracking to multi-dimensional data collection by adding spatial (position), temporal (operation history), and operational (drive control parameters) dimensions to the management information structure
2Loss of information
If comprehensive drive control information is collected, then management information sufficiency is improved, but data transmission and processing complexity increases
Solution Approach 1:
The system extracts only the necessary drive control information (accelerator opening degree, brake status, transmission state) from the complex electronic controller data stream, filtering out redundant information while maintaining management sufficiency
Solution Approach 2:
The communicator acts as an intermediary between the electronic controller and the server, pre-processing and formatting the drive control information to reduce transmission complexity and enable efficient server-side processing
3Productivity
If real-time data transmission is implemented, then operational monitoring capability is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic data transmission at appropriate intervals rather than continuous transmission, balancing real-time monitoring needs with energy conservation by transmitting data only when operational updates are meaningful

AI summary
A management system 1 includes an electronic controller 14 and a communicator 15.The electronic controller 14 is arranged at a self-propelled lawn mower 10 and performs a drive control of a drive source 11 that drives the lawn mower 10. The communicator 15 is arranged at the lawn mower 10, includes an apparatus that communicates with the electronic controller 14 and with a server 30 via a network, acquires drive control information used for the drive control from the electronic controller 14, and transmits the drive control information to the server 30.
