Description

[0001] This application is a divisional application of a patent application entitled "Smart integrated electricity meter and solar panel system using the smart integrated electricity meter". The application date of the original application is July 16, 2019, and the application number is 201910642240.4. Technical Field

[0002] The present invention relates to the field of solar panel communication technology, and in particular to an intelligent integrated electric meter and a solar panel system using the intelligent integrated electric meter. Background Art

[0003] With the massive consumption of fossil energy and the serious environmental problems it brings, the use of sustainable and cleaner energy has become a global consensus. As an inexhaustible new energy source that does not cause any environmental problems, solar energy is increasingly valued and developed by various countries. Although my country's photovoltaic industry developed relatively late, with the strong advocacy of the country, my country's photovoltaic power generation technology has ranked first in the world.

[0004] The existing solar panel system will be installed with at least two energy measuring devices (also referred to as electric meters). The solar panel is connected to an electric meter via a solar inverter. The energy testing device outputs electricity to the public utility smart meter. The public utility smart meter transmits the power output data to the public utility system server via wireless transmission. The public utility system server is connected to the company system server via wireless / wired transmission communication. The company system server communicates wirelessly with the application and the end-user application so that the solar system company or the end-user can understand the power generation status and confirm how much electricity can be sold to the power company. In order to maintain the performance of the solar panel and understand the efficiency conversion, many environmental information, such as temperature, humidity and light intensity, will be collected and sent through different communication devices or systems. Sent to the solar energy system company or the power company for data analysis; for example: the sunshine intensity meter is wired to the first communication module, and is wirelessly connected to the company's system server via the first communication module; the temperature / humidity sensor is wired to the second communication module, and is wirelessly connected to the company's system server via the second communication module; the water meter is wired to the third communication module, and is wirelessly connected to the company's system server via the third communication module; the home Internet of Things gateway is connected to the company's system server via wireless communication; because it needs to be sent separately through different communication devices, it is easy to cause too much communication data and inefficient data processing; and the installation cost of these communication devices is very expensive, and it is not easy to change after installation and system implementation.
