Step 3, main control unit receive and process the sampled signal of the power module and the sampling letter of environmental parameter collecting unit
Number, the main control unit sends drive signal to Q drivers driving circuit and LD driving circuits, and driving ultraviolet laser starts work
Make；
Step 4, moisture condensation judging unit read built-in moisture condensation point and inquire chart, and adopting in conjunction with the environmental parameter collecting unit
Sample signal judges that moisture condensation risk, the sampled signal include the sampled signal of temperature value/humidity value outside cabinet, the temperature in cabinet
The sampled signal of temperature value in the sampled signal and ultraviolet laser of angle value/humidity value, judge in cabinet circuit there are
When the risk that condenses, the main control unit sends drive signal to the TEC driving circuits and the TEC water coolings module is driven to carry out heat
Amount transfer condenses to avoid the circuit in the cabinet, is judging that there are moisture condensation risks for optical module in ultraviolet laser
When, the main control unit to the TEC driving circuits send drive signal drive the TEC water coolings module carry out heat transfer with
The light path in the ultraviolet laser is avoided to condense.
