when the power generation value is smaller than the power generation threshold value, judging that the power generation efficiency of the solar panel is abnormal, generating a maintenance signal, and carrying out parameter confirmation and maintenance operation on the solar panel by staff;
the specific operation steps of the safety monitoring platform comprise:
step C1: the safety monitoring platform takes a preset distance of a solar panel as a center as a radius to set a detection area, acquires harmonic data XBI and harmonic duration SCi in the area, and utilizes a formulaObtaining a harmonic coefficient XS; XB0 is expressed as the harmonic frequency of other devices in the environment;
step C2: obtaining real-time output voltage DYI of solar panel by using formulaObtaining a stable value TS of the solar panel; wherein (1)>Expressed as a correction factor, the value is 0.3116; c1 is a preset proportionality coefficient; DYi is real-time voltage after the voltage conversion of the solar panel; DY0 is a standard voltage during voltage conversion of the solar panel;
step C3: comparing the stable value with a preset stable range value, and generating a red alarm signal when the stable value is smaller than or equal to the minimum value in the stable range value;
when the stable value is between the efficiency range values, generating a yellow early warning signal;
when the stable value is greater than or equal to the maximum value in the stable range value, generating a green normal signal;
the display module displays the steps of: in a one-day working time period of the solar panel, obtaining the light intensity efficiency value of each fixed time node and the generated energy of the solar panel by taking the fixed time node as a unit; and establishing a two-dimensional coordinate system of the light intensity efficiency value and the solar panel generating capacity by using the light intensity efficiency value as an abscissa and the solar panel generating capacity as an ordinate.
