Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems for working vehicles do not prevent theft of agricultural vehicles, such as the system disclosed in Japanese Unexamined Patent Application Publication No. 2016-76801, do not prevent theft of agricultural vehicles, as the system disclosed in Japanese Unexamined Patent Application Publication No. 2016-123, fail to prevent theft of agricultural vehicles, as the system disclosed in Japanese Unexamined Patent Application Publication No. 2016-76801, fail to prevent theft of vehicles, as the system disclosed in Japanese Unexamined Patent Application Publication No. 2016-76801, merely reports theft to the related party, failing to prevent theft.
Innovation Solution
A monitoring system with a remote communication terminal and a working vehicle that includes a monitored mode and a manual mode, where the vehicle transitions to manual mode upon receiving permission from the remote communication terminal, equipped with sensors and imagers to detect entry and authenticate users, and a controller to manage transitions between modes, including a short-range communication terminal for local control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system only reports theft to remote parties, then communication functionality is simple, but the system cannot prevent theft of the working vehicle
Solution Approach 1:
The system dynamically transitions between monitored mode and manual mode based on authentication results. The working vehicle operates in monitored mode during remote operation, then transitions to manual mode after successful authentication, enabling adaptive security responses without requiring permanently complex hardware
Solution Approach 2:
The system performs preliminary authentication of the operator before allowing mode transition. The sensor detects operator presence, the imager captures authentication data, and the controller validates credentials before switching from monitored to manual mode, preventing theft proactively rather than merely reporting it
2Reliability
If the system requires authentication before mode transition, then security is improved, but the operation process becomes more complex
Solution Approach 1:
The system uses the operator's own biometric data (fingerprint, face, or voice) for authentication. The sensor and imager automatically capture this data, and the controller compares it against stored credentials, eliminating the need for separate authentication devices or complex manual verification processes
Solution Approach 2:
The system supports multiple authentication methods (fingerprint sensor, imager for face/voice recognition) that can be used interchangeably. This multi-functional approach provides security through various biometric modalities while maintaining a uniform user experience across different authentication types
3Measurement precision
If the system uses multiple sensors and imagers for authentication, then authentication accuracy is improved, but the device complexity increases
Solution Approach 1:
The system employs asymmetric authentication architecture where the sensor and imager work in complementary roles rather than redundant parallel systems. The sensor detects presence and captures primary biometric data, while the imager provides secondary verification, creating an asymmetric multi-layer authentication process that enhances accuracy without simply duplicating components

AI summary
A monitoring system includes a remote communication terminal, and a working vehicle including a monitored mode in which a monitored operation monitored by the remote communication terminal is allowed and a manual mode in which a manual operation is allowed. The working vehicle includes a controller configured or programmed to, upon receiving a permission signal from the remote communication terminal when the working vehicle is in the monitored mode, bring the working vehicle into a permission mode in which the monitored mode is allowed to transition to the manual mode.
