Construction Machinery Information Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote management systems for construction machinery can only transmit and receive information when the machinery is in a start-on state, making it impossible to manage information when the machinery is in a start-off state.
Innovation Solution
An information management system that includes a control server, a memory unit on the construction machinery to store driving information during a start-off state, and a communication terminal that can read and transmit this information to the control server upon request, along with features like anti-theft alarm and range setting, and power mode switching to a backup battery when the regular battery voltage is low.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication terminal transmits information to the control server only when the construction machinery is in a start-on state, then the system structure remains simple, but the ability to manage information in start-off state is lost
Solution Approach 1:
The memory unit stores driving information in advance when the construction machinery is in start-off state, before the machinery is started. This preliminary storage enables the communication terminal to transmit information to the control server even when the machinery was previously off, thus resolving the contradiction by maintaining simple system structure while achieving reliable information management across all states
Solution Approach 2:
The memory unit acts as an intermediary component between the machinery control device and the communication terminal. It bridges the gap by storing information during start-off state when the control device is inaccessible, allowing the communication terminal to later retrieve and transmit this stored information to the control server without requiring the machinery to be in start-on state
2Loss of information
If the communication terminal transmits all driving information continuously, then complete information management is achieved, but communication costs increase and redundant data transmission occurs
Solution Approach 1:
Instead of transmitting all driving information continuously, the system transmits only the necessary information selectively. The control server can request specific information as needed, and the communication terminal transmits only those selected data items from the memory unit, avoiding redundant transmissions while ensuring complete information management for requested parameters
Solution Approach 2:
The control server sends requests for specific information to the communication terminal based on operational needs. This feedback mechanism allows the system to transmit only the information that is currently needed, preventing redundant data transmission while ensuring that complete information is available when requested, thus reducing communication costs
