Problems solved by technology

In the actual application process, such as under cloudy conditions, the illumination changes drastically, and the difference in the upload time of component data will lead to data asynchrony, resulting in invalid data
The current technology / product data upload method is either through the host query method, which is slow and the data is not synchronized; or the average value or cumulative sum of uploaded data for a period of time is used, which is not real-time enough and cannot reflect real-time changes

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] see figure 1 , the photovoltaic power generation system includes a battery panel array 10 , a server 900 , an inverter 20 , and a busbar 30 . The battery panel array 10, the server 900, the inverter 20, and the bus bar 30 are connected in series to form a loop. The DC power generated by the battery panel 100 is converted into AC power by the inverter 20 and input to the grid. The battery panel array 10 may be formed by connecting multiple battery panels 100 in series.

[0023] Each solar panel 100 in the solar panel array 10 adopts a solar panel monitoring system 200 of the present invent...

Abstract

The invention discloses a data uploading method for a solar panel monitoring system and the solar panel monitoring system. The data uploading method for the solar panel monitoring system includes the steps that parameter information of each string of photovoltaic cells in each solar panel of a photovoltaic power generation system is collected, the parameter information is modulated into pulse carrier signals, and the pulse carrier signals are loaded to a bus bar, connected with the solar panels in series, of the photovoltaic power generation system; after a server, connected to the bus bar in series, of the photovoltaic power generation system receives the pulse carrier signals, the parameter information of the solar panels is obtained through demodulation, data completely uploaded within a set time difference delta T is regarded as valid data, and other data is discarded. The intelligent monitoring method is introduced into the solar panels of the photovoltaic power generation system, the conflict probability is reduced through random data sending, the data validity is guaranteed through a synchronous data uploading mechanism, and thus the solar panels are monitored and analyzed in teal time. The invention further discloses the solar panel monitoring system.

Description

technical field [0001] The invention relates to a data uploading method and a system applying the data uploading method, in particular to a data uploading method of a battery board monitoring system and the battery board monitoring system. Background technique [0002] The safety performance of photovoltaic systems has been paid more and more attention. Due to the huge number of components, it has become an important aspect of safety. There is a lack of reliable and stable component-level monitoring and analysis systems in the market. In the actual application process, such as under cloudy conditions, the illumination changes drastically, and the difference in the upload time of component data will lead to data asynchrony, resulting in invalid data. The current technology / product data upload method is either through the host query method, which is slow and the data is not synchronized; or the average value or cumulative sum of uploaded data for a period of time is used, whic...
