Handheld Farm Implement Control for Automated Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld control devices for mobile farm implements lack the ability to automate unloading processes and efficiently communicate with various communication protocols used by different farm implements, limiting their functionality and interoperability.
Innovation Solution
A handheld control device that automates unloading by issuing commands and monitoring conditions, and can communicate with multiple mobile farm implements using different communication protocols, such as ISO 11783 and ISO 11898, allowing wireless data collection from outside the implement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a handheld control device uses a single communication protocol, then it can communicate reliably with farm implements using that protocol, but it cannot interface with multiple mobile farm implements using different communication protocols
Solution Approach 1:
The handheld control device incorporates multiple communication protocol interfaces (ISO 11783, ISO 11898, and other wireless protocols) to enable universal communication with different types of mobile farm implements. This multi-functionality allows a single device to adapt to various communication standards without requiring multiple separate control devices, thereby improving interoperability while maintaining reliable communication through protocol-specific handling.
2Productivity
If unloading processes are manually controlled, then the operator has full control over each step, but the process requires continuous user intervention and more time
Solution Approach 1:
The system implements automated unloading control where the mobile farm implement autonomously performs unloading operations based on pre-programmed sequences and sensor feedback. The controller automatically monitors conditions (such as料位 sensors detecting material levels) and executes corresponding actions (activating augers, controlling discharge gates) without continuous manual intervention, thereby increasing productivity while reducing the operational burden on the user.
Solution Approach 2:
The control system incorporates sensor feedback mechanisms that continuously monitor the unloading process (material level, auger operation status, discharge rate) and automatically adjust operations based on detected conditions. This closed-loop feedback enables the system to self-regulate the unloading process, maintaining optimal performance and reducing the need for manual oversight while ensuring complete and controlled unloading.
3Ease of operation
If display terminals are mounted inside mobile farm implements, then data can be displayed at the location of operation, but the operator cannot access information from outside the implement
Solution Approach 1:
The handheld control device serves as an intermediary between the mobile farm implement's internal systems and the operator. It wirelessly receives data from sensors and controllers inside the implement and displays information on its own external display interface, allowing operators to access real-time data and control functions from outside the implement without needing to physically enter or interact with internal display terminals, thereby improving accessibility and saving time.
Data Source
AI summary
A method of unloading mobile farm implements is presented. Unloading the mobile farm implement is accomplished by transmitting commands to unfold an auger arm and to open a container door and by monitoring weight measurements from the implement.
