Description
Technical Field
[0001] This invention relates to the field of power Internet of Things (IoT) data acquisition and management technology, specifically to a method and system for evaluating the installation location of electricity meter collectors. Background Technology
[0002] Against the backdrop of the rapid development of smart grids and the Internet of Things (IoT) for electricity, electricity meter readers, as key information collection and transmission nodes, undertake the functions of efficient aggregation and remote transmission of electricity metering data. In recent years, with the widespread application of wireless communication technologies such as Low Power Wide Area Networks (LPWAN), NB-IoT, and LoRa in electricity meter reading systems, the deployment density of electricity meter readers has continued to increase, placing higher demands on the rationality of their installation locations. Scientifically planning the installation location of readers not only directly affects the quality of data communication but also relates to the stability of system operation and maintenance costs. Therefore, research on optimizing the installation location of electricity meter readers has gradually attracted industry attention, and some technical solutions have attempted to provide auxiliary installation guidance based on communication signal coverage maps and building structure diagrams.
[0003] Existing technologies often focus on simple references to static parameters, lacking a comprehensive evaluation method that is systematic, multi-dimensional, and dynamically optimized. They typically rely on manual experience combined with a single indicator (such as communication signal strength) for rough site selection, failing to fully consider the complex coupling relationships between multiple factors such as electromagnetic compatibility, structural stability, maintenance accessibility, and construction feasibility. This makes the actual installation effect susceptible to fluctuations in the site environment, and communication quality and subsequent maintenance reliability difficult to guarantee. Existing technologies generally fail to establish complete candidate location models, lacking dynamic screening and nonlinear reasoning optimization mechanisms. They cannot adaptively adjust indicator weights and target parameters for different installation scenarios (such as high-interference industrial areas and old building environments), resulting in insufficient intelligence and precision in installation decision-making. Summary of the Invention
[0004] In view of the above-mentioned problems, the present invention is proposed.
[0005] Therefore, the technical problem solved by this invention is that existing methods for evaluating the installation location of electricity meter collectors have single evaluation indicators, lack multi-dimensional comprehensive consideration, cannot achieve dynamic screening and optimization of candidate locations, lack adaptive optimization capabilities for complex scenarios, and how to achieve scientific planning and intelligent auxiliary decision-making for the installation location of electricity meter collectors.

[0007] As a preferred embodiment of the method for evaluating the installation location of the electricity meter collector described in this invention, the step of outputting a comprehensive evaluation score of the candidate location based on the scene weight adjustment rules and the indicator weights includes: dynamically adjusting the indicator weights according to the scene weight adjustment rules, outputting a comprehensive evaluation score of the candidate location, and generating a ranking optimization result.

[0010] Another objective of this invention is to provide an electricity meter data collector installation location evaluation system that can output a comprehensive evaluation score for candidate locations based on candidate location adaptability scores, scene weight adjustment rules, and indicator weights. This solves the problems of current electricity meter data collector installation location evaluation methods, which cannot achieve dynamic screening and optimization of candidate locations and lack adaptive optimization capabilities for complex scenarios.
[0011] As a preferred embodiment of the meter data acquisition device installation location evaluation system of the present invention, it includes: a multi-source environmental data acquisition module for the installation area, a candidate installation location model construction module, a candidate location adaptability score output module, a comprehensive evaluation module, and an installation location recommendation module; the multi-source environmental data acquisition module for the installation area is used to collect multi-source environmental data of the installation area in real time, including building structure spatial layout, meter distribution density, obstruction information, wall material, power access conditions, wireless communication signal quality, and electromagnetic interference source distribution; the candidate installation location model construction module is used to construct a candidate installation location model using preset spatial topology rules after the multi-source environmental data acquisition module for the installation area is completed, and to screen locations that meet the safety requirements. The system constructs a candidate installation location set by selecting a set of location nodes that meet the installation conditions. The candidate location suitability score output module, after the candidate installation location model construction module outputs the candidate installation location set, calls a predefined multi-factor inference rule base to infer and output a candidate location suitability score for each candidate location based on indicators such as communication signal quality, electromagnetic compatibility, ease of later maintenance, structural stability, and construction feasibility. The comprehensive evaluation module, after the candidate location suitability score output module outputs the candidate location suitability score, outputs a comprehensive evaluation score for the candidate locations based on the candidate location suitability score and scene weight adjustment rules, generating a ranking result.

Furthermore, by dynamically adjusting the weights of each indicator according to scenario weight adjustment rules, the comprehensive evaluation score can be adapted to different application environments, achieving intelligent optimization tailored to local conditions and improving the adaptability of this method to complex and variable installation scenarios. Finally, by outputting the optimal installation location based on comprehensive ranking and generating an auxiliary decision-making report containing recommendation reasons, location score details, and precautions, the installation process becomes more standardized and scientific, reducing decision-making biases caused by differences in human experience. Overall, this invention effectively improves the scientific nature of the installation location planning of electricity meter collectors, the reliability of communication, and the convenience of subsequent maintenance, thereby enhancing the stability and controllability of system operation.
