The invention discloses a photovoltaic module monitoring method and system. The monitoring method comprises the following steps that a plurality of data acquisition nodes are uniformly arranged in anarea comprising a plurality of photovoltaic modules, wherein the data acquisition nodes comprise a sensor group, a data processor and a wireless communication device; the data acquisition nodes are used for acquiring the ambient temperature of the photovoltaic modules, the temperatures of the photovoltaic modules, the working voltages of the photovoltaic modules, and the currents and position information of the photovoltaic modules; the processor transmits the information to a photovoltaic background; the photovoltaic background obtains the photovoltaic modules which suffer from faults according to the ambient temperature, temperatures, working voltages and currents of the photovoltaic modules; and the photovoltaic background transmits the data information of the photovoltaic modules whichsuffer from faults to an operation and maintenance center. The requirement for monitoring the photovoltaic module faults in real time under an extreme environment is met, and the working states of the photovoltaic modules can be monitored in real time.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a photovoltaic module monitoring method and system. Background technique [0002] As an emerging energy technology, distributed photovoltaic technology can simultaneously meet the energy demand, reduce the greenhouse effect and improve the reliability of power supply. It is an important direction for the development of energy technology in the future world. With the vigorous development of the photovoltaic industry, if the photovoltaic power station is not monitored, it is impossible to know whether the photovoltaic power station is operating normally, which may cause inestimable losses. Monitoring the photovoltaic power plant system can not only detect and solve faults in time, but also reduce maintenance costs. [0003] In the existing technology, the monitoring method of solar photovoltaic power plants is low-efficiency manual inspection. Since the 21st century, the moni...
