Cargo Handling Detection Using Backup Light Voltage Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo handling systems face increased costs and complexity due to the use of load sensors and cameras for detecting cargo handling actions, which can be damaged and require significant installation efforts.
Innovation Solution
Detect cargo handling actions by monitoring the backward movement of cargo handling vehicles using the activation of their backup lights, employing sensors to detect the voltage of these lights and transmitting this information to a management system for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a load sensor is used to detect cargo handling action, then cargo handling action can be detected, but cost increases and installation time and effort increase
Solution Approach 1:
The system utilizes existing vehicle data (backward movement information from vehicle speed sensors) to detect cargo handling actions, allowing the vehicle's own operational data to serve the dual purpose of vehicle control and cargo handling monitoring, thereby eliminating the need for additional dedicated sensors
Solution Approach 2:
The vehicle speed sensor serves multiple functions: controlling vehicle operation and detecting cargo handling actions through backward movement detection, making the sensor system multi-functional and reducing overall system cost
2Difficulty of detecting and measuring
If a camera is used to detect cargo handling action, then cargo handling action can be detected, but installation requires large-scale alteration increasing cost and time
Solution Approach 1:
The system leverages existing vehicle operational data (backward movement information) to detect cargo handling actions, eliminating the need for external imaging equipment and complex installation infrastructure
Solution Approach 2:
The invention extracts useful information (backward movement patterns) from existing vehicle operational data, separating the cargo handling detection function from dedicated hardware and deriving it from常规 vehicle operation parameters
3Difficulty of detecting and measuring
If a load sensor is attached to a fork, then cargo handling action can be detected, but the sensor can be damaged depending on attaching position
Solution Approach 1:
The system uses the vehicle's own operational data from protected onboard sensors to detect cargo handling actions, eliminating exposure of sensors to harsh physical environments where they would be vulnerable to damage
Solution Approach 2:
The system uses backward movement information as an intermediary indicator to infer cargo handling actions, rather than directly measuring physical cargo parameters with sensors exposed to the cargo handling environment
