Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of photovoltaic (PV) installations face challenges in efficiently locating specific malfunctioning modules within large installations due to the lack of accurate maps, often relying on manual methods that are time-consuming and prone to errors, especially when power losses occur.
Innovation Solution
The development of methods to generate automatic or semi-automatic physical maps of PV installations using localization algorithms, GPS technology, wireless signal analysis, and thermal imaging to determine the precise location and ordering of PV devices, including the use of barcode scanning and Power Line Communication techniques to create detailed layout maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual methods are used to locate PV modules and create installation maps, then operators can obtain location information, but the process is time-consuming and prone to human errors
Solution Approach 1:
The patent replaces manual mechanical methods (walking through installation, copying ID numbers) with automated electronic systems including mobile devices with cameras, barcode scanners, GPS receivers, and wireless communication transceivers to automatically capture module identifiers and location data
Solution Approach 2:
The system enables self-service by allowing modules to automatically transmit their identification information through embedded identifiers (barcodes, RFID tags) that can be read remotely, and using GPS to automatically determine location without human intervention in data collection
2Reliability
If manual methods are used to create installation maps, then maps can be generated, but human errors cause inaccurate information to be recorded
Solution Approach 1:
The patent replaces error-prone manual data collection with automated electronic systems including mobile devices with cameras, barcode scanners, GPS receivers, and wireless communication transceivers that objectively capture and transmit data without human error
Solution Approach 2:
The system creates accurate digital copies of module identification information by capturing images of barcodes, reading RFID tags, or receiving electronic transmissions from modules, storing these data copies in a centralized database for reliable reference
3Productivity
If automated localization methods are implemented, then time and accuracy are improved, but system complexity increases
Solution Approach 1:
The patent employs multi-functional mobile devices that combine camera, barcode scanner, GPS receiver, and wireless communication capabilities in a single unit, reducing the need for multiple separate specialized devices while maintaining comprehensive functionality
Solution Approach 2:
The system uses a centralized database as an intermediary that receives, stores, and processes location and identification data from various modules, coordinating information flow between diverse components and providing a unified interface for troubleshooting

AI summary
Various implementations described herein are directed to a method for determining an order of power devices connected in a serial string. A command is transmitted, to at least one first power device of a plurality of power devices, to change an output electrical parameter. At least one electrical signal is caused to be transmitted from at least one second power device of the plurality of power devices. At least one measured value responsive to the electrical signal is received from at least one of the plurality of power devices. A determination is made, by analyzing the at least one measured value, which ones of the plurality of power devices are ordered in the serial string between the at least one first power device and the at least one second power device.
