Photovoltaic Distribution Network Mesh Configuration for Stable Wi-Fi Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In photovoltaic distribution networks, communication between photovoltaic devices and routers is unstable due to poor Wi-Fi signal quality, especially for devices far from the router, leading to connectivity issues and high hardware costs when scaling.
Innovation Solution
A photovoltaic distribution network system and method that uses a distribution network control device to generate and transmit device lists and network configuration information, enabling devices to broadcast their information and establish direct or indirect connections with the router without additional hardware, forming a mesh network architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If photovoltaic devices are connected to router through Wi-Fi, then communication between devices and router is established, but communication quality deteriorates for devices far from router
Solution Approach 1:
The patent introduces intermediary devices (photovoltaic devices with better signal quality) to relay communication between the router and distant photovoltaic devices. These intermediary devices forward data packets, enabling distant devices to communicate effectively despite poor direct Wi-Fi signal quality, thus resolving the contradiction between establishing communication and maintaining communication quality.
2Reliability
If additional hardware such as antenna extension lines or Wi-Fi signal amplifiers are arranged, then communication quality is improved, but hardware cost increases
Solution Approach 1:
The patent enables photovoltaic devices to serve dual functions: both generating electricity and providing network communication services. Devices with good signal quality automatically act as communication relays for distant devices, eliminating the need for additional hardware like signal amplifiers or extension lines. This self-service approach resolves the contradiction by using existing device resources instead of adding expensive hardware.
3Reliability
If conventional methods are used to improve communication quality, then some devices achieve stable connection, but overall system scalability is limited
Solution Approach 1:
The patent segments the network communication function into multiple distributed nodes (photovoltaic devices), where each device can independently provide communication services to others. This segmentation transforms the traditional single-router architecture into a mesh network, enabling the system to scale dynamically as new devices are added without requiring centralized control or additional infrastructure, thus resolving the contradiction between communication stability and system scalability.

AI summary
A photovoltaic distribution network system and a network configuration method therefor are provided. The photovoltaic distribution network system includes a distribution network control device, multiple photovoltaic devices and a router. The distribution network control device is configured to generate a device list including device information of to-be-configured devices, and transmit the device list and network configuration information to the to-be-configured devices. The to-be-configured device is configured to broadcast device information of the to-be-configured devices based on the network configuration information. The router is configured to receive the device information broadcast by the to-be-configured devices, and establish a communication connection with a first distribution network device among the to-be-configured devices based on device information of the first distribution network device. The first distribution network device is configured to receive device information broadcast by a to-be-configured device not in a communication connection, and establish a direct or indirect communication connection with the to-be-configured device not in the communication connection. With the method, the communication quality between the photovoltaic device and the router is improved, and the hardware cost of the photovoltaic distribution network system is reduced.
