Management Server for Real-Time Electric Power Tool Status Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing electric power tools in construction sites are inefficient in providing timely status updates, leading to delayed repairs and potential disruptions in work processes due to reliance on error information for monitoring tool states.
Innovation Solution
An information processing apparatus that acquires position and actuation information from electric power tools, generates work status data, and outputs display data to show the tool's status, enabling real-time monitoring and management of tool usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If error information is used for monitoring tool states, then the monitoring system is simple to implement, but the response time is delayed and work process disruptions occur
Solution Approach 1:
The system performs preliminary actions by acquiring actuation information and generating work status data before actual errors occur. The management server continuously monitors tool status through actuation information from the controller, enabling early detection of potential issues and timely interventions before they escalate into work-disrupting failures.
2Measurement precision
If real-time actuation information is acquired and processed, then the work status monitoring becomes timely and accurate, but the system complexity and data processing requirements increase
Solution Approach 1:
The management server performs multiple functions: acquiring actuation information, generating work status data, determining regional information, extracting tool information, and generating display data. This multi-functional approach consolidates complexity into a single central system rather than distributing it across multiple devices, making the system manageable despite its comprehensive capabilities.
Solution Approach 2:
The management server acts as an intermediary between the electric power tools and the display device. It receives actuation information from tool controllers, processes this data to generate work status information, and then outputs display data to visualization devices. This intermediary role simplifies the overall system architecture by centralizing data processing and communication management.
3Loss of information
If position information and actuation information are continuously monitored, then tool location and status visibility improve, but the data transmission and processing load increases
Solution Approach 1:
The system extracts only the necessary actuation information from the tool controllers - specifically information indicating that the tool is actuated. Rather than transmitting all possible data, the system selectively extracts relevant work status data, reducing communication overhead and energy consumption while maintaining comprehensive monitoring capabilities.
