Method for data conversion between serial port and Ethernet and device thereof

Abstract

The invention discloses a method for data conversion between a serial port and Ethernet and a device thereof. The method comprises the following steps: when micro-grid data enters a data conversion device through a serial port, firstly performing physical caching through the serial port, then performing data caching through a main controller, and then sending the micro-grid data to a network port, and finally transmitting the micro-grid data to a remote network from the network port; and when a remote network instruction enters the data conversion device through the network port, firstly performing data caching through the main controller, then performing physical caching through the serial port, and then transmitting the remote network instruction to a micro-grid through the serial port. According to the method and the device thereof disclosed by the invention, serial port data of the micro-grid is converted into network port data and is sent out through networks, and the remote data instruction is also received back through the networks; and the method and device can prepare for the long-distance transmission of real-time big data, have the characteristics of double caching, high-efficiency and high-speed transmission, configurability and user friendliness, can meet the requirements of big data transmission, and are convenient to carry out big data analysis and other functions.

Description

technical field [0001] The invention belongs to the technical field of micro-grids, and in particular relates to a method and device for data conversion between a serial port and an Ethernet. Background technique [0002] Micro-grid (micro-grid or microgrid), also known as micro-grid, refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads and monitoring and protection devices. An autonomous system capable of self-control, protection and management, which can operate in parallel with the external grid or in isolation. [0003] With the continuous increase of the scale of my country's power system, the continuous increase of the interconnection of the national power grid system, and the influence of factors such as diversification of power consumption, my country's power system is facing increasing pressure on safety and reliability. The micro-grid is an effective measu...

Problems solved by technology

[0004] In traditional power monitoring systems such as microgrids, data is mostly transmitted in the form of serial ports. This form of transmission can only be used within a limited distance. Once it is far away from the device, this form of data transmission cannot be used.

Therefore, the data that can be collected by the traditional monitoring system is limited data. Many data that reflect the key indicators of system operation cannot be sent long-distance due to the large amount of data and the small bandwidth of the serial port, resulting in a large amount of data that cannot be monitored in real time.

Especially for wind power converters in wind turbines, due to the complexity and harshness of the wind farm environment, a large part of the converters in the wind farm only use serial ports with stable characteristics, which cannot realize functions such as data access and remote operation, and the data limited transfer speed
