Embodiment 1

[0025] Embodiment 1 The system implementation of the present invention is specifically as follows:

[0026] 1. Design center data collection network architecture diagram (such as figure 1 ) and sub-center data collection and energy supply network architecture diagram (such as image 3 );

[0027] 2. Establish a photovoltaic power generation system data acquisition sub-center. A. Select and purchase sensors. The temperature and humidity measurement adopts SHTll sensor from Sensirion Company of Switzerland, the illumination sensor adopts TSL2561 light intensity sensor produced by TAOS Company, and the wind speed and direction sensor adopts EC-9S(X) digital wind speed sensor from Changsha Jiake Electronic Instrument Co., Ltd. (wind direction) sensor. The battery module adopts the 110W product of Zhejiang Chuangyu Solar Technology Co., Ltd.; the inverter adopts the SHJS06-V-5000VA model product of Shanghai Jingshan Solar Technology Co., Ltd., and outputs 50 / 60Hz (2% self-stabi...

Embodiment 2

[0032] Select different regions where the four extreme climate conditions of high temperature, high cold, windy sand, and salt humidity are located to deploy 4 different solar cell power station data collection sub-centers. Battery power plant data collection via GPRS (eg Figure 4 ) to the photovoltaic power generation system data management center. The center processes the received data: 1) Compare the differences in power generation and life characteristics of solar cells produced by the same manufacturer under different climatic conditions, and provide enterprises with guidance on the prediction of user environment power generation; 2) For the collected The fault information of the sub-center power station is analyzed in time, and the processing fault information is issued. If a certain module cannot work, it can automatically "suspend" the module, that is, switch to the state of "connecting its left and right modules in series" through electrical signals; 3 ), compare th...

Abstract

The invention discloses a remote data acquisition and management system and an implementation method thereof. The system consists of a data acquisition and management center and a plurality of data acquisition and management branch centers, and data are transferred among the center and the branch centers in real time in a wireless mode. The branch centers are responsible for collecting electrical parameters of various environments and photovoltaic systems and wirelessly send the electrical parameters to the center, and the center is responsible for receiving data of each branch center and modeling via analysis so as to obtain relationship of service lives and generating capacity of the photovoltaic systems in different regions and different environments with the environments. The data center can remotely collect information of photovoltaic power stations in different regions and under different climatic conditions in real time through the system, and analyzes the data of the photovoltaic power stations under different climatic conditions so as to obtain relationship of generating capacity of battery modules under different climatic conditions with environmental parameters. The system has the advantages that real-time wireless long-distance (1000Km) transmission is achieved through GPRS (general packet radio service), a photovoltaic battery, a controller and an energy storage battery pack form a continuous energy supply system to supply energy to the branch centers for data acquisition, and service lives of batteries in different regions are predicted through data analysis.

Description

technical field [0001] The invention relates to a data remote collection and management system and an implementation method thereof. More precisely, the present invention relates to a multi-parameter, self-powered, real-time photovoltaic system data acquisition and management system and its implementation method, belonging to the field of electronic technology Background technique [0002] As one of the major solar cell production countries, China is relatively backward in the construction of standards for cell and power station systems. At present, internationally renowned American Renewable Energy Laboratory (NERL), Japanese Industrial Research Institute (AIST) and Germany's Institute of Solar for Energy Systems (Fraunhofer ISE) have become internationally renowned battery testers. Key developer of laboratory and international battery standards. China currently does not have a third-party certification body with independent certification capabilities. One of the main rea...
