Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] A Linux-based photovoltaic grid-connected Web monitoring system, its structure is as follows figure 1 shown. The system mainly includes: photovoltaic grid-connected system, core controller FPGA, Web server, SQLite database, computer or mobile terminal, etc. The photovoltaic grid-connected system is connected to core 1 in the core controller FPGA, and the web server is connected to core 0. Core 1 and core 0 inside the FPGA can perform real-time data interaction. At the same time, the web server is also connected to a computer or mobile terminal. Among them, the core controller FPGA adopts a heterogeneous dual-core mode, core 1 generates the control signal of the photovoltaic grid-connected system, and core 0 is equipped with a Linux system to run network services, data storage and monitoring functions. First build a Linux system in the ...

Abstract

The invention discloses a photovoltaic grid-connected Web monitoring system based on Linux. The system comprises a photovoltaic grid-connected system, a core controller FPGA, a Web server, a computer or a mobile terminal and so on. A heterogeneous dual-core mode is employed in the core controller FPGA. A core 1 generates a control signal for the photovoltaic grid-connected system. The core 0 carries a Linux system to operate functions such as network service, data storage and monitoring. Firstly, the Linux system is established in the core 0 of the core controller FPGA; secondly, the photovoltaic grid-connected Web monitoring system is designed, wherein the design comprises steps of selecting a Web server, designing system architecture, designing a common gateway interface (CGI), selecting a database, designing communication between the database and the CGI, and designing Web monitoring interface; and finally, application design of the core 0, start of a heterogeneous dual-core processor and selection of a communication mode are provided. According to the selected CGI interface technology, the server and a webpage can interact with each other very well. According to the transplanted Boa server, few resources are occupied and the system overhead is low. According to the monitoring system based on the Web, the photovoltaic grid-connected system can be monitored whenever and wherever possible.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a Linux-based photovoltaic grid-connected Web monitoring system. Background technique [0002] With the rapid consumption of global energy reserves, the supply of traditional energy sources such as coal, oil, and natural gas has become increasingly tight. In order to alleviate the energy and environmental crisis, the development and utilization of primary renewable energy sources such as wind energy and solar energy have received high attention. Photovoltaic power generation, as a form of new energy generation, has a very good development prospect. However, it is greatly affected by the environment, and due to discontinuous and uncertain power generation, grid-connected operation will affect the power quality of the grid, and even affect the normal operation of the grid. In order to understand the operation status of the grid-connected system in real time and control the system, it is ...
