The invention relates to a method and system for quantifying contaminated QR Codes. In the method, contamination comprises data and error correcting codeword contamination, boundary contamination, position detection figure contamination, correction figure contamination, positioning figure contamination, version information contamination and format information contamination; and contamination quantification of different degrees is performed on different positions of bar codes according to different contamination models, wherein the contamination degree of the QR codes is not greater than the error correcting capability of the bar codes themselves for error codes, the quantity of encoding characters of the QR codes is equal to the quantity of characters corresponding to data codewords specified by a current bar code version and an error correcting grade, the condition of adding filling characters does not exist, the data and error correcting codeword contamination does not comprise residual bits, and the contamination mode can employ an early-stage printing contamination mode and a later actual contamination mode. According to the invention, the problems of incapability of quantitatively evaluating scanning performance of a scanner for contaminated bar codes at present, large test personnel cost and lack of representativeness of test results are solved.

The invention discloses an audio acquisition tooling, a method and a cloud server. The tooling comprises an identification scanning unit, an audio acquisition microphone, a micro-control unit and a communication unit, wherein the identification scanning unit is used for scanning one-dimensional code information uniquely for identifying a loudspeaker carried on each loudspeaker to be delivered; the one-dimensional code information is sent to the micro-control unit; the audio acquisition microphone is used for acquiring a sound signal of each loudspeaker to be delivered while pre-determined frequency sweeping sound is played in a quiet room; the micro-control unit compares the sound signal with a standard frequency sweeping sound signal stored in a storage unit; if not same, the loudspeaker to be delivered is not qualified; otherwise, the loudspeaker to be delivered is qualified; and the sound signal and the one-dimensional code information of the qualified loudspeaker are sent to a cloud side through the communication unit, such that the cloud side stores the sound signal as a standard audio flow. According to the audio acquisition tooling, the method and the cloud server disclosed by the invention, whether the loudspeaker is qualified or not is determined by acquisition of the sound signal of the loudspeaker; when the loudspeaker is qualified, the sound signal of the qualified loudspeaker is sent to the cloud side, such that the cloud side stores sound signals of a lot of qualified loudspeakers; and basis is provided for machine vibration test of audio output equipment.

The invention discloses a method for testing an embedded memory, the embedded memory includes eMMC and DDR, wherein the method for testing the embedded memory includes: receiving a first signal instruction for testing the eMMC, and according to the first signal The instruction controls the eMMC to start testing, and feeds back a corresponding test signal; receives a second signal instruction generated according to the test signal to test the DDR, and controls the DDR to start testing according to the second signal instruction; Obtain the test results of the eMMC and DDR, and determine whether the embedded memory is qualified according to the test results of the eMMC and DDR. The embedded memory testing method of the present invention can test eMMC and DDR at the same time, save testing time, improve testing efficiency and reduce cost. In addition, the invention also discloses an embedded memory testing device, equipment and computer storage medium.
