Embodiment Construction

[0064] In order to make the objects and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with examples. It should be understood that the following words are only used to describe one or several specific implementation modes of the present invention, and do not strictly limit the protection scope of the specific claims of the present invention.

[0065] This embodiment is applied to the design of a communication software upper computer system where the master-slave needs to be adaptively connected and the number and type of slave devices are uncertain, the communication type and transmission content of multiple slave devices are uncertain, and the size of the data packet is not known in advance. . (Its communication data only transmits the original data through EMS data, so as to change it to the Ethernet data packet format for easy reading by the host computer)

[0066] The purpose of the following design i...

Abstract

The invention discloses a method for fully automatic communication and hardware identification between an upper computer and a lower computer based on a photovoltaic inverter grid-connected energy storage management system. This method combines the specific situation of photovoltaic inverter grid-connected energy storage management system, and according to the specific characteristics of various Ethernet-based communication protocols, a communication strategy and software management strategy that can adapt to hardware changes are invented. This strategy can automatically find and identify the EMS for handshake, then query the EMS model locally and on the Internet to obtain its communication setting information, communicate again and automatically obtain the software and hardware information of various subsystems that are connected to the EMS by hardware, and finally automatically complete the communication settings , Manage the storage mode of the database system, generate system charts, and finally realize the dynamic management of the software functions of the upper computer.

Description

technical field [0001] The invention relates to a method for fully automatic communication and hardware identification between an upper computer and a lower computer based on a photovoltaic inverter grid-connected energy storage management system. Background technique [0002] Worldwide environmental pollution and energy shortages have forced people to work harder to find and develop new energy sources. In the process of finding and developing new energy sources, people naturally turn their attention to various renewable alternative energy sources. Photovoltaic power generation is one of them. Grid-connected photovoltaic power generation means that the direct current generated by solar modules is converted into alternating current that meets the requirements of the mains grid through a grid-connected inverter and then directly connected to the public grid. [0003] Grid-connected photovoltaic power generation can be divided into grid-connected power generation systems with...
