and A7, obtaining the total occurrence time of the photoelectric reaction, and obtaining the glass length according to the rotating speed of the transmission structure.
7. The self-controlling method of an automatic detecting device for sound-proofing effect of glass as claimed in claim 6, wherein said step M3 includes the following sub-steps:
a8, rounding down to obtain the calculated number A by dividing the obtained glass length by the width of the detection box
A9, obtaining detection times 1 when A is less than or equal to 4, obtaining detection times 2 when A is more than 4 and less than or equal to 8, and obtaining detection times 3 when A is more than 8;
a10, changing the width of the detection box to be flush with the width of the glass by a mechanism on the gantry;
a11, if the top end of the glass to be detected is detected by the door frame in the changing process, stopping transmitting the structure until the width of the detection box is adjusted;
a12, the transport structure conveys the glass to be inspected into the portal.
8. The self-control method of an automatic detection device for sound-proofing effect of glass according to claim 6 or 7, wherein said step M6 comprises the following sub-steps:
b1, performing once-lasting 45-decibel rain sound simulation for half a minute to obtain noise reduction data d 1;
b2, carrying out 70 dB noise simulation for 15 seconds once to obtain noise reduction data d 2;
b3, carrying out 98 decibel singing voice treble simulation lasting for 5 seconds once to obtain noise reduction data d 3;
b4, carrying out weighted average on the data d1, d2 and d 3;
and B5, judging that the average value is qualified if the noise reduction is more than 22 dB, and judging that the average value is unqualified if the noise reduction is less than 22 dB.
