Embodiment Construction

[0040] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] like figure 1 As shown, a photovoltaic micro-grid energy management system based on LoRa communication installs the power monitoring terminal on each photovoltaic array in the photovoltaic micro-grid system of the smart factory. Since the photovoltaic arrays are widely distributed, the physical location of each power monitoring terminal Far apart, the present invention uses LoRa technology to realize remote management of multi-terminal equipment. The LoRa communication module provides interfaces with different sensors and is integrated into a sensing terminal to collect surrounding information and send it back to the LoRa base station at a long distance. The LoRa base station can receive coverage The data reported by all sensing terminals in the system, the front-end information is converted into protocols, and connected to the photo...

Abstract

The invention relates to a LoRa technology based photovoltaic microgrid energy management system, and belongs to the technical field of industrial internet of things. The system includes multiple electric energy monitoring and collecting nodes; large-capacity electric energy monitoring terminal data transmission can be realized through a LoRa technology; and collected data can be connected to thesystem, so that LoRa technology based functions of on-line monitoring, real-time analysis processing and decision optimization of photovoltaic microgrid electric energy quality can be realized. The system can perform comprehensive monitoring analysis on the multiple monitoring points of an intelligent factory photovoltaic microgrid by combining the LoRa technology and a photovoltaic microgrid, sothat the accurate grasping of comprehensive control and operation states can be realized, and therefore, the communication levels of electric power systems can be improved, and control and adjusting on the operation states of microgrid electric power equipment can be performed on a management platform.

Description

technical field [0001] The invention belongs to the field of industrial internet of things, and relates to a photovoltaic microgrid energy management system based on LoRa technology. Background technique [0002] Electricity is an indispensable source of energy in our society today. In the past, non-renewable energy sources such as coal, oil, and natural gas have always been the main source of energy for people to carry out various production activities. With the increasingly serious global energy and environmental problems, distributed power generation based on renewable energy has become an important part of energy strategic planning for sustainable development. The development and utilization of distributed power is the main way to solve the current energy problems. At present, countries all over the world have started extensive research on distributed generation systems. In this context, people began to look for new energy sources. As one of the new energy sources in t...
