The invention relates to the technical field of defect detection, in particular to a
solar water heater PCB control panel structure optimization method and
system. The method comprises the steps of obtaining thermal parameters of all components, calculating time weighted thermal power, generating a board heat source
distribution diagram, evaluating condensation risks of all areas of a board according to the heat source
distribution diagram and a preset installation inclination angle of a PCB control board, generating a condensation
risk distribution diagram, constructing an
electromagnetic coupling model between a key
signal wire and a power supply wire, basic
electromagnetic interference intensity is calculated, condensation
risk distribution on the key
signal wiring path is extracted, the basic
electromagnetic interference intensity is corrected to obtain a comprehensive
risk assessment value, and wiring is optimized according to a priority strategy when the comprehensive
risk assessment value is larger than a preset threshold value. According to the scheme, the condensation
risk area of the board can be predicted and quantified, the condensation risk and the
electromagnetic interference risk can be associated, and the working reliability of the PCB control board in the damp and hot alternating environment is improved.
