Description

Technical Field

[0001] The present invention relates to the technical field of data collection and management of electric power Internet of Things, and in particular to a method and system for evaluating the installation position of an electric meter collector. Background Art

[0002] Amid the rapid development of smart grids and the power Internet of Things (IoT), meter collectors, as key information collection and transmission nodes, are responsible for the efficient aggregation and remote transmission of electricity metering data. In recent years, with the widespread adoption of wireless communication technologies such as low-power wide area networks (LPWANs), NB-IoT, and LoRa in power meter reading systems, the deployment density of meter collectors has continued to increase, placing higher demands on the rationality of their installation locations. Strategically planning the installation location of meter collectors not only directly impacts data communication quality but also affects system operational stability and maintenance costs. Consequently, research on optimizing meter collector installation locations has gradually garnered industry attention, with some existing solutions attempting to provide installation guidance based on communication signal coverage maps and building structure diagrams.

[0003] Existing technologies often focus on simple references to static parameters and lack comprehensive evaluation methods that are systematic, multi-dimensional, and dynamically optimized. Rough site selection often relies on manual experience combined with a single metric (such as communication signal strength). This fails to fully consider the complex coupling relationships between multiple factors, such as electromagnetic compatibility, structural stability, maintenance accessibility, and construction feasibility. This results in actual installation results being susceptible to fluctuations in the on-site environment, making it difficult to guarantee communication quality and subsequent maintenance reliability. Existing technologies generally fail to establish a complete candidate location model and lack dynamic screening and nonlinear inference optimization mechanisms. This makes it impossible to adaptively adjust indicator weights and target parameters for different installation scenarios (such as high-interference industrial areas and older building environments), resulting in insufficient intelligence and refinement in installation decisions.
