Abstract

The invention relates to a photovoltaic hydrogen production system. The photovoltaic hydrogen production system comprises at least one photovoltaic hydrogen production device and a converging node which can communicate with the photovoltaic hydrogen production device wirelessly; each photovoltaic hydrogen production device comprises a photovoltaic assembly, a direct-current conversion assembly, an electrolytic cell and a wireless sensing assembly; and each wireless sensing assembly comprises a sensor module, a controller and a wireless communication module, wherein the sensor module is used for collecting the state data of each photovoltaic hydrogen production device, the controller is used for controlling the work state of each photovoltaic hydrogen production device according to the state data, and the wireless communication module is used for sending the state data to the converging node through a wireless network. By collecting the site state data by using the wireless sensing assembly of each photovoltaic hydrogen production device, the process monitoring data of the photovoltaic hydrogen production system can be accurate and complete. Because the wireless sensing assembly of each photovoltaic hydrogen production device can communicate with the converging node through a wireless network, the network-based management and the state data of a photovoltaic hydrogen production device array can be monitored in real time, and the conversion efficiency of the photovoltaic hydrogen production system can be improved.

Description

technical field [0001] The invention relates to the field of energy management, in particular to a photovoltaic hydrogen production system. Background technique [0002] At present, energy shortage has become the main factor restricting industrial development, therefore, it is particularly important to find renewable energy that can replace petrochemical energy. [0003] Among the clean energy that has been researched and applied so far, hydrogen energy has the advantages of high calorific value, high energy density, no pollution in the energy conversion process, wide range of uses, and huge reserves in the universe. It is considered to be one of the most ideal alternative energy sources. . However, since the hydrogen element on the earth mainly exists in two forms of hydrocarbons and water, hydrogen energy is usually obtained only through the decomposition of hydrocarbons and electrolysis of water, which makes the hydrogen production process consume a lot of electric energ...
