Frequency range x, and and setting value, i.e., the peak frequency range of the ceramic tile surveyed not hollowing point compares in advance.If frequency range x does not exist
In setting range, is instructed then single-chip microcontroller will at once issue ink gun 170, it is allowed to be marked to ceramic tile.Then single-chip microcontroller
All programs and module recovery wait and judging next time to reset condition.If frequency range x is within the set range, all journeys
Sequence and module are restored to reset condition at once, and waiting judges next time.Wherein, single-chip microcontroller is compared two frequency amplitudes and sentences
Disconnected output control instruction is the control method of this field routine, with quilt as it is known to those skilled in the art that the present invention is not done has
Body limits.
In this present embodiment, the ink gun 170 is connected with the Audio Controller, in the ceramic tile, there are hollowings
When to the ceramic tile carry out ink-jet to mark the ceramic tile with hollowing, convenient for worker repair.
Ceramic tile is prestored in ceramic tile hollow drum automatic detection instrument in the present embodiment taps sound pitch sound peaks frequency
Various percussion audio signals are passed through frequency dividing by the relationship between objective data, the signal characterized by the crest frequency for tapping sound
Device 150, single-chip microcontroller carry out logic judgment, automatic identification sound pick-up 130 acquire percussion voice signal in real time to ceramic tile hollowing into
Row identification, and be marked by ink gun 170.In this present embodiment, audio analysis software can be advanced with to knock
Sound carries out time and frequency domain analysis, establishes the connection to the subjective feeling and time-domain and frequency-domain signal for tapping sound, and it is existing to exclude overtone
A possibility that as having an impact.Performance can most be stablized by, which choosing, whether there is the crest frequency of hollowing structure as characteristic signal.It is empty
Bulging audio data analysis example is as shown in Figure 2.Sound pitch increases with ceramic tile center hollowing area and is reduced, to percussion sound
Signal carries out multiple averaging, carries out Fourier transformation and normalization by audio analysis software, obtains the line chart such as Fig. 2.By
For Fig. 2 it is found that the frequency data for being 7.8 by not hollowing to hollowing area are by gradually becoming smaller greatly, general trend is descending.
In this present embodiment, it is also installed with electric power connecting mouth 1102 or battery power supply module on the mobile microscope carrier 100, it can
It is powered, can also be powered by battery with being connect by power supply line with power outlet, wherein the battery is preferably lithium electricity

Ceramic tile hollow drum automatic detection instrument in the present embodiment has at low cost, light weight, accuracy height, high degree of automation
The features such as, there is excellent suitable dress, complete full automatic identification and floor tile hollowing region is marked on ceramic tile table with marking pen
Face, entire detection process realize intelligence, and high degree of automation, monitor in real time without artificial, time saving, less manpower, accurately
Degree is high, effectively avoids missing inspection, and erroneous detection and repetition detect.Hollowing situation directly can be marked on ceramic tile surface, under being convenient for
One step reparation.It is expected to replace traditional hammering method, solves traditional artificial hammering method, accuracy is low, and artificial subjectivity is big, automates journey
Spend it is low, the drawbacks of high labor cost.
For make it is further understood that in the present embodiment ceramic tile hollow drum automatic detection instrument principle, such as Fig. 3
It is shown, the course of work of ceramic tile hollow drum automatic detection instrument in the present embodiment will be illustrated.
Ceramic tile hollow drum automatic detection instrument in the present embodiment is placed in tile floor and carries out detection test.Ceramic tile hollowing is certainly
Dynamic detector after being powered up, can combine according to GPS geo-location system and infrared inductor 190 carry out detection track first
Then planning selectes detection zone and starts to detect, can pause 500 milliseconds in each test point, the control of steering engine 120 taps hammer 110
Ground is tapped, sound pick-up 130 starts to carry out sampled voice while single-chip microcontroller performs after rotation steering engine 120.Sound pick-up 130
After stopping sampling, by electromagnetic induction principle, frequency divider is passed to after the voice signal received is converted to analog signal
150, the percussion sound signal of acquisition is divided, frequency divider 150 will compare all frequency ranges of received sound
Amplitude, then take out the frequency range x of maximum value, the microcontroller 160 and setting value, i.e., the ceramic tile surveyed in advance not hollowing when
Crest frequency compare.If frequency range x is not equal to setting value, single-chip microcontroller marks demand head 170 to ceramic tile
Note.Then all programs and module recovery are automatically moved into next test point to reset condition, equipment.If frequency range x is equal to
Setting value, all programs and module are restored to reset condition at once, and mobile microscope carrier 100 is automatically moved into next test point.If
Surely 10 lis are moved, as next test point.Next test point close to wall side moving distance less than 10 centimetres, by it is practical away from
From after movement be used as next test point.Ceramic tile hollow drum automatic detection instrument in time-consuming 60 minutes the present embodiment about has detected greatly
The tile floor of about 72 square meters is found at ceramic tile hollowing 7.Then primary artificial reinspection, for comparing, artificial detection consumption have been carried out
When 2 hours, only verify 3 hollowing points.By opening floor tile inspection, the ceramic tile hollow drum automatic detection instrument in the present embodiment is examined
Entirely accurate, has the ability to find out hollowing of the area less than 10 square centimeters, and desk checking only have found 3 10 square centimeters with
On hollowing, do not find out 2 hollowings of the area less than 10 square centimeters, and miss out 2 10 square centimeters or more of hollowing.It can
The ceramic tile hollow drum automatic detection instrument seen in the present embodiment ratio in testing accuracy and missing inspection problem is substantially better than artificial detection.Inspection
The speed tested is also obviously than manually faster.
In addition, in order to protrude the innovative part of the utility model, it will not be with solution the utility model in the present embodiment
The technical issues of proposed, the less close feature of relationship introduced, but this does not indicate that there is no other structures in the present embodiment
And functional character.
It should be noted that diagram provided in the present embodiment only illustrates the basic structure of the utility model in a schematic way
Think, only shown in schema then with related component in the utility model rather than component count when according to actual implementation, shape and
Size is drawn, when actual implementation kenel, quantity and the ratio of each component can arbitrarily change for one kind, and its assembly layout type
State may also be increasingly complex.
In conclusion the utility model structure novel, practicability is high, can be automatic and accurately judges that whether ceramic tile is empty
Drum, marks the ceramic tile of hollowing；Secondly the utility model drives without manpower, can plan detection track automatically, carry out
Automatic job avoids the omission and repetition of test point.So the utility model effectively overcome it is in the prior art it is various lack
It puts and has high industrial utilization value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
