PTO Generator Work Management for Monitored Machine Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work management systems for working machines with generators fail to effectively operate and manage working devices using generator power, as they do not adequately obtain and utilize operation information for efficient management.
Innovation Solution
A work management system that includes a power transmission mechanism to transmit power from the PTO shaft and motor to the working device, a PTO shifter to control rotating speed, and a controller to manage the working device based on obtained operation information, displayed on a display device, with a coupler device for attachment to the working device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the working device is operated by the generator power, then the productivity and energy utilization are improved, but the device complexity and control difficulty increase
Solution Approach 1:
The system incorporates an information acquisition device that collects operation information from the working device, and a controller that uses this feedback to automatically adjust and optimize the operation of the working device, thereby improving productivity while managing system complexity through intelligent control
Solution Approach 2:
The generator serves multiple functions: it provides power to the working device, charges the battery, and supplies power to the controller and information acquisition device, reducing the need for separate power sources and simplifying the overall system architecture
2Measurement precision
If operation information is obtained and used for management, then the management precision and working optimization are improved, but the device complexity increases
Solution Approach 1:
The working device performs self-monitoring through the information acquisition device, automatically collecting and providing operation information to the controller without requiring external monitoring systems, thereby improving measurement precision while minimizing additional complexity
Solution Approach 2:
The information acquisition function is integrated into the existing working device structure, combining multiple functions (power generation, power distribution, operation monitoring, and control) into a unified system rather than adding separate independent systems

AI summary
To operate a working device with power of a generator, obtain operation information in operation of the working device, and manage working of the working device based on the obtained operation information. A work management system (100) includes a generator (15) attached to a structure body (25) that is provided to a transmission case (10) of a working machine (1), configured to be driven by power transmitted from a PTO shaft (19), and configured to transmit power to a working device (3) provided in the working machine, an information obtaining portion (81) configured to obtain operation information representing operation of the working device that is activated by the power from the generator, a work management portion (82) configured to manage working of the working device based on the operation information obtained by the information obtaining portion, and a controller portion (83) configured to control the working device based on the operation information obtained by the information obtaining portion.
