The conversion module converts the current second electrical energy information into the single-chip microcomputer chip for recording, and after obtaining the current second electrical energy information, the single-chip microcomputer chip controls the second rotating motor, so that the second photoreceptor is turned back into the controller box; Step 4, the single-chip microcomputer chip finds the corresponding current first electric energy reference value from the set table for the obtained current first electric energy information and current second electric energy information, using the current second electric energy information as a search condition, and compares; Step 5: If it occurs, the first electric energy critical value ≤ the current first electric energy information < the current first electric energy reference value, then it is judged that the glass ball or the photosensitive plate is not polluted or slightly polluted, and no automatic cleaning operation is required at this time; , the first electric energy threshold≤the current first electric energy information<the first electric energy critical value, then it is judged that the glass ball or the photosensitive plate is slightly polluted, and step 6 is executed; If the glass ball or photosensitive plate is heavily polluted, go to step 8; Step 6: When slight pollution occurs, every night of every week, the single-chip microcomputer chip controls the first rotating mechanism to rotate 360 degrees around the glass ball, and at the same time controls the solenoid valve of the water inlet pipe, so that a plurality of first nozzles are sprayed on the outer surface of the glass ball. The cleaning liquid, the brushes and the first scraper on the first semicircular track, and at the same time, the outer surface of the glass ball is cleaned in a circumferential manner without dead ends; The cleaning liquid is sprayed on the photosensitive plate, and the surface of the first photoreceptor is cleaned alternately by two second scrapers; Step 7: After the cleaning is completed, the single-chip microcomputer chip controls the second rotating mechanism, so that the second semicircular orbit stops near the bottom of the circular drifting table on one side of the glass ball; the single-chip chip controls the first rotating mechanism to make the first semicircular orbit around the glass ball. The circular bleaching table on the other side swings up and down, and at the same time controls the solenoid valve of the water inlet pipe, so that a plurality of first nozzles spray water to the circular bleaching table, the brush and the first scraper are soaked in the clean water and the circular bleaching Under the action of scraping, the pollutants are thrown out; Step 8, when heavy pollution occurs, the glass ball and the photosensitive plate are automatically cleaned according to the methods of Step 6 and Step 7 that night; Step 9: After the single-chip microcomputer chip obtains the current first power information, if the size of the current first power information does not change, it is not necessary to collect the current second power information; if the current first power information size changes, record the current first power information. electric energy information, and correspondingly collect the current second electric energy information, and perform steps 3 to 8; if there is currently no first electric energy information, there is no sunlight, and the current second electric energy information does not need to be collected; Step 10: The single-chip microcomputer chip transmits the power generation information and power information to the remote terminal through the power grid or wireless network. The technicians can obtain the power generation information and power information from the remote terminal through the mobile phone APP, perform manual intervention, and command the single-chip microcomputer chip at any time for cleaning. Operation.
