Microgrid alarm data remote transmission device and method based on edge computing technology

Abstract

The invention provides a micro-grid alarm data remote transmission device and method based on an edge computing technology. The micro-grid alarm data remote transmission device based on the edge computing technology comprises a power supply module, a serial port communication module, a network port, a USB interface, a wireless internet access module, an indicating lamp, a GPS module and a processor, and the power supply module supplies power to the whole device and provides 12-48V AC power access; the serial port communication module supports RS-485 / RS-232 and GPIB ; the network ports support two network ports, namely an LAN and a WAN; the wireless internet access module supports a standard internet access SIM card; and the GPS module is arranged. The micro-grid alarm data remote transmission device and method based on the edge computing technology have the advantages that usability, safety, economical efficiency and the like are greatly improved, use convenience can be greatly improved, and alarm data can be quickly clouded.

Description

technical field [0001] The present invention relates to the field of microgrid technology, in particular to a device and method for remote transmission of microgrid alarm data based on edge computing technology. Background technique [0002] A microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. Composed of small power generation and distribution systems. [0003] Microgrids mainly operate in areas with underdeveloped power such as islands. Due to the poor natural environment, it brings more difficulties to the monitoring and maintenance of microgrids, especially for the monitoring of alarm data, which can timely and accurately display the microgrid Information such as current faults and alarms of the power station, so that maintenance personnel can take corresponding measures in the first time. The traditional alarm monit...

Problems solved by technology

[0005] There are certain disadvantages in the above methods. First, it is necessary to customize and develop a data analysis program on the server side. This program cannot be solidified and needs to be changed according to the change of the field data type, which has great complexity and professionalism.

Secondly, since DTU devices are almost transparently transmitted, after the cloud receives the data, it needs to judge whether there is an alarm according to the preset variable thresholds, and the values ​​within the normal range also need to be repeatedly analyzed, which wastes a lot of transmission resources.

This undoubtedly increases the application complexity and brings great difficulties to the application of non-software technicians in the field of microgrid
