Working Vehicle Attachment Identification With Buffered NFC Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for identifying attachments on working vehicles unnecessarily increase processing load on the identification module by determining the position of an attachment every time an acceleration signal is received, leading to inefficiency.
Innovation Solution
A working vehicle system that includes a linkage, a receiver to receive periodic wireless signals from attachments with identification information, and a controller to selectively identify the attached attachment based on predefined conditions, such as signal strength and vibration information, reducing unnecessary processing by storing identification information for a predetermined time before making a selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the identification module determines the position of an attachment every time the first acceleration signal is received, then the attachment position can be continuously tracked, but the processing load on the identification module increases needlessly
Solution Approach 1:
The system performs preliminary actions by storing received identification signals in a buffer before actually processing them. The identification module only processes signals when the attachment is detected to be attached to the working vehicle, rather than processing every received signal immediately. This preliminary buffering action reduces unnecessary processing while maintaining the ability to accurately identify attachments.
Solution Approach 2:
The system uses feedback from the attachment detection mechanism to control the processing behavior. When the attachment is detected to be attached to the working vehicle, the system switches to processing mode and identifies the attachment based on stored signals. This feedback-based control ensures processing only occurs when necessary, reducing overall processing load while maintaining detection accuracy.
2Reliability
If the identification module processes every received acceleration signal, then attachment identification can be performed continuously, but unnecessary processing occurs when the attachment is not actually attached
Solution Approach 1:
The system performs preliminary buffering of identification signals before processing. The buffer stores signals during the attachment attachment period, and processing only occurs when the attachment is actually attached to the working vehicle. This preliminary action prevents unnecessary energy consumption while maintaining reliable identification when needed.
Solution Approach 2:
The attachment detection mechanism serves the dual purpose of both detecting attachment status and controlling processing behavior. The same detection information that identifies whether the attachment is attached also controls whether processing should occur, making the system self-regulating and preventing wasteful energy consumption during non-attachment periods.

AI summary
A working vehicle includes a linkage, a receiver to receive wireless signal(s) from transmitter(s) in/on the attachment(s) and including identification information of the attachment(s), and a controller configured/programmed to select identification information of the attachment attached to the linkage from the identification information included in the received wireless signal(s), and start a process based on the selected identification information. The controller is configured/programmed to cause a memory and/or storage to store, for a first period of time, the identification information included in the received wireless signal(s), and when the attachment is attached to the linkage, perform a first selecting process to select identification information satisfying a first condition from the stored identification information, and, if no identification information satisfying the first condition is stored, perform a second selecting process to select identification information satisfying a second condition from identification information included in wireless signal(s) received after the attachment is attached.
