Battery Swap Station Vehicle Size Detection for Safe Entry Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery swap stations lack the ability to detect vehicle size, which can lead to damage to vehicles and facilities when vehicles with extra-wide or extra-high accessories attempt to enter, as they do not meet the required swapping dimensions.
Innovation Solution
Implementing a method and system that uses ranging devices and image collection devices, along with a convolutional neural network, to detect vehicle size by determining if a vehicle is within a predetermined swap region and performing width and height measurements, thereby controlling the swapping operation based on these measurements to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle size detection is not implemented, then the battery swap station can operate with simpler equipment, but vehicles with extra-wide or extra-high accessories may cause damage to facilities and themselves
Solution Approach 1:
The patent implements vehicle size detection before the battery swapping operation commences. The detection system (using image collection devices and ranging devices) scans the vehicle's width and height in advance, and the control system compares these measurements against preset thresholds to determine whether the vehicle is suitable for swapping. This preliminary detection prevents vehicles with excessive dimensions from entering the swapping area, thereby avoiding potential damage to facilities and the vehicles themselves.
Solution Approach 2:
The patent introduces a control system as an intermediary between the vehicle and the battery swapping facility. This control system receives detection data from image collection devices and ranging devices, processes the information, and makes decisions about whether to permit the swapping operation. The intermediary control system coordinates the detection results with the swapping execution, ensuring that safety requirements are met before any physical interaction occurs.
2Measurement precision
If manual inspection of vehicle size is used, then the system remains simple, but the efficiency and accuracy of detecting vehicle dimensions are reduced
Solution Approach 1:
The patent replaces manual inspection methods with automated detection systems. Image collection devices (such as cameras) capture images of the vehicle, and ranging devices (such as laser range finders) measure distances automatically. These electronic and optical systems substitute for human visual inspection and physical measurement, providing more precise and consistent dimension data without requiring manual intervention.
Solution Approach 2:
The detection system operates autonomously without requiring human operators. The image collection devices automatically capture vehicle images, the ranging devices automatically measure dimensions, and the control system automatically processes the data and makes decisions. This self-service capability eliminates the need for manual inspection while maintaining high accuracy and improving operational efficiency.
3Measurement precision
If multiple ranging devices at different heights are deployed, then vehicle height detection accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The patent divides the height detection task into multiple segments by deploying ranging devices at different vertical heights. Each ranging device is responsible for measuring a specific height range or perspective of the vehicle. By segmenting the detection task across multiple devices positioned at different elevations, the system achieves comprehensive and accurate height measurement that would be difficult or impossible with a single device.
