Construction Equipment Remote Control Key-Off Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote management systems for construction equipment cannot transmit or receive data, nor update firmware, when the equipment is in a key-off state due to power supply limitations, leading to inefficiencies and potential operational issues.
Innovation Solution
A system that uses standby power from a battery to maintain electronic control devices in a sleep mode, allowing data transmission and firmware updates even when the equipment is in a key-off state by waking up specific devices as needed for operations and switching back to sleep mode after completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the equipment uses power generated from an engine or battery only when driven, then power consumption is minimized, but data transmission and firmware updates cannot be performed when the equipment is in a key-off state
Solution Approach 1:
The system performs preliminary actions by storing operation information in non-volatile memory before the key-off state occurs, and pre-establishes communication protocols that can be activated immediately when needed, allowing data transmission and firmware updates to proceed without requiring the engine to be running
Solution Approach 2:
The patent introduces an intermediary communication module that acts as a bridge between the control station and equipment controllers, capable of maintaining minimal power operation and handling data transmission independently of the main engine power state, thus enabling communication during key-off periods
2Loss of information
If all operation information is uploaded to the control station before stopping the start, then data accessibility is improved, but communication expenses increase due to the increase of communication data
Solution Approach 1:
The system extracts only the essential and recently changed operation information for transmission to the control station, rather than uploading all historical data. This selective data extraction reduces communication volume and expenses while maintaining data accessibility for monitoring and analysis purposes
Solution Approach 2:
The system performs preliminary filtering and prioritization of data before transmission, identifying and preparing only the most critical operation information for immediate upload, thereby reducing the overall data volume that needs to be communicated while ensuring important information remains accessible
3Power
If the equipment operates electronic control devices only when the starting key is in the on state, then power supply efficiency is maintained, but firmware updates cannot be performed when the equipment is in a key-off state
Solution Approach 1:
The system implements dynamic power management that allows electronic control devices to transition between sleep mode and active state based on operational needs. During key-off periods, the system can dynamically activate specific controllers for firmware updates without maintaining continuous power to all devices, thus preserving overall power supply efficiency while enabling update capability
Solution Approach 2:
The communication module is designed with multi-functionality, serving both as a power management interface and a firmware update conduit. This universal component can handle multiple tasks including data communication, power state coordination, and firmware transmission, enabling firmware updates during key-off states without compromising the overall power supply architecture
