Abstract
The invention discloses a multi-station full automatic laser power measuring method and a multi-station full automatic laser power measuring system. The multi-station full automatic laser power measuring system comprises one or a plurality of laser devices, and one or a plurality of main electric control circuit boards, beam splitter mirrors and relays which are respectively in one to one correspondence with the laser devices, wherein the main electric control circuit boards receive lasers of the laser devices reflected by the beam splitter mirrors corresponding to the main electric control circuit boards, analyze and judge the reflected lasers, and control a power source of the laser devices to be off through the relays when the reflected lasers are determined to be abnormal. By using the method, an operator does not need to personally monitor the laser devices, and accordingly raying probability of the operator is reduced, and measuring efficiency is improved greatly due to the fact that underreporting probability basically does not exist by analyzing and judging the reflected lasers through the main electric control circuit boards.
