Management Server Authentication for Work Machine Data Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication systems for working machines lack reliability in data transmission and confidentiality, particularly in agricultural settings, where personal information and operational data are not securely managed, leading to potential unauthorized access and data integrity issues.
Innovation Solution
A data communication system that utilizes a management server to authenticate and authorize wireless communication between a data communication device on the working machine and a mobile terminal, ensuring that only registered and related devices can access data, thereby enhancing data reliability and confidentiality through secure key management and coded user/machine identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data communication device merely outputs measurement information to outside of machine, then any communication equipment can easily obtain measurement information, but data transmission reliability is lowered
Solution Approach 1:
A management server is introduced as an intermediary between the data communication device and mobile terminals. The management server authenticates mobile terminals, verifies their authorization status, and manages the relationship between users and working machines. This mediator enables controlled access while maintaining data transmission reliability through authentication and authorization mechanisms.
2Productivity
If database stores personal information on workers, then work performances can be stored and managed, but confidentiality of personal information is poor
Solution Approach 1:
The system performs preliminary authentication and authorization actions before allowing data access. The management server authenticates mobile terminals in advance, verifies their authorization status, and establishes authorized relationships between users and working machines before any data transmission occurs. This preliminary security check protects personal information confidentiality while enabling work performance management.
3Adaptability or versatility
If machine performing agricultural tasks is not related to work performances in database, then database can store work performances, but machine cannot be incorporated into work plan
Solution Approach 1:
The management server establishes a feedback mechanism that links working machines to work performances through authentication and authorization. When a mobile terminal accesses data from a working machine, the management server verifies the authorized relationship and records the connection. This feedback loop enables machines to be incorporated into work plans while maintaining manageable system complexity through centralized management.

AI summary
Authentication between a data communication device and a mobile terminal can be readily achieved such that data obtained by the data communication device can be transmitted to the mobile terminal. A management server (50a to 50d) includes a user management database (60) in which mobile terminal identification information on the mobile terminal (40a, 40b) and working machine identification information on a sold working machine are registered to be related to each other, a user registration determination unit (53) adapted to determine whether or not the mobile terminal (40a, 40b) and the working machine are registered to be related to each other on the basis of the mobile terminal identification information and the working machine identification information outputted from the mobile terminal (40a, 40b) and the mobile terminal identification information and the working machine identification information stored in the user management database (60), and an authorization information output unit (54) adapted to output an authorization key necessary for wireless communication between the mobile terminal (40a, 40b) and the working machine in a case where the user registration determination unit (53) determines that the mobile terminal (40a, 40b) and the working machine are registered to be related to each other.
