Working Machine ID Code Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines, such as tractors and backhoes, face security issues with data rewriting and unauthorized operation due to poor authentication methods, allowing third parties to easily access and control these machines.
Innovation Solution
A system that uses a mobile terminal for secure communication with the working machine's control device, employing ID code registration and checking mechanisms to ensure only authorized users can access and control the machine, with ID codes being stored and transmitted securely to enable or disable data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile phone is used to rewrite data in the control device without authentication, then data rewriting is enabled, but security against data rewriting deteriorates
Solution Approach 1:
An authentication code serves as an intermediary between the mobile phone and the control device. The mobile phone must present this code to the control device, which verifies it against a pre-stored authentication code before allowing data rewriting. This intermediary mechanism enables secure data rewriting by filtering unauthorized access attempts.
2Ease of operation
If an authentication code is stored in the working machine that can be freely set by a user, then the power source can be turned on, but security against unauthorized operation deteriorates
Solution Approach 1:
The control device performs preliminary verification by checking the authentication code from the mobile phone against a pre-stored authentication code before enabling power source control. This preliminary action ensures that only authorized users can activate the power source, preventing unauthorized operation while maintaining ease of use for legitimate users.
3Ease of operation
If settings are changed on a display device around the driver's seat, then settings can be made conveniently, but the ability to change settings remotely deteriorates
Solution Approach 1:
The control device is designed to accept settings changes from multiple sources: both the local display device around the driver's seat and remote mobile phones. This multi-functionality allows users to change settings conveniently at the machine or remotely via mobile device, adapting to different operational scenarios while maintaining ease of use.

AI summary
In addition to improving security of data communication between a control device and a mobile terminal, to make it possible to easily make the data communication. A working machine of the present invention is provided with a control device that can make wireless communication with a mobile terminal 3 storing a mobile-use ID code and stores a working machine-use ID code, wherein the control device is provided with: ID code checking means 41 adapted to check the mobile-use ID code obtained by ID code obtaining means 40 and the working machine-use ID code with each other; data communication means 42 adapted, in the case where as a result of the checking by the checking means, matching between the ID codes is established, to allow data communication between the mobile terminal 3 and the control device, and in the case where the matching is not established, not to allow the data communication; and ID code registration means adapted to register the working machine-use ID code in the mobile terminal 3 as the mobile-use ID code.
