Abstract
A tile floor cavity detector comprises a microprocessor, an A/D converter, an acoustoelectric sensor, an audio frequency amplifier, an electroacoustic transducer, a display buffer and a display. The tile floor cavity detector is characterized in that the microprocessor generates a variable frequency current, the frequency of the variable frequency current is controlled by the A/D converter, the variable frequency current is amplified by the audio frequency amplifier and drives the vibration head of the electroacoustic transducer to vibrate, a tile is periodically acted by the vibration head of the electroacoustic transducer and vibrates in a forced manner, cavities between the tile and the ground or between the tile and a wall compose a resonant tank, so the volume is greatly increased because of the resonance effect, and a large sound can be heard, thereby cavities in the floor or the wall are detected, the resonance sound wave frequency can be detected, and the sizes of the cavities can be accurately read out in the display through the transition of the display buffer. The method of the detector for detecting the cavities between the tile and the ground or between the tile and the wall has the advantages of simplicity, high efficiency, easy reaching of a common consensus between a construction side and a householder, convenient timely rectification, and elimination of the hidden trouble of the cavities. The detector provides a reference for the setting of a home floor tile construction quality standard by a relevant department.
Description
Technical field
The present invention relates to a kind of family expenses finishing detecting instrument, be specifically related to the empty detector of a kind of tile floor.
Background technology
the ground paving ceramic tile, the wall tiling, finishing has become fashion, finishing has changed people's life, finishing has beautified living environment, give people's Beautiful treat, but there are many problems in the finishing implementation process, during as tiling for the material saving, often packing material is unreal between ground and ceramic tile, stay many empty hidden danger, owing to lacking examination criteria and cheap apparatus, detect empty hidden danger very difficult, make the householder find it hard to tell about one's suffering, construction party is but felt reassured and emboldened on account of the support, be further intensified, its harm is: made on the one hand many rubbish engineerings, cause the social resources waste, aggravate on the other hand interpersonal contradiction, affect social harmonious development, so design this detector.
Summary of the invention
The objective of the invention is for above-mentioned deficiency, provide a kind of tile floor empty detector.
solution of the present invention realizes by following technological means: the empty detector of tile floor, comprise acoustoelectric sensor, A/D converter, microprocessor, note amplifier, electroacoustic transducer, vibration head, Display Register, display, shell, wheel, it is characterized in that: microprocessor is controlled the work of whole circuit, microprocessor produces the frequency conversion electric current, A/D converter is controlled the frequency conversion power frequency, note amplifier amplifies the frequency conversion electric current, the vibration head vibration of electroacoustic transducer, ceramic tile is done forced vibration, utilize between ceramic tile and ground or the composition resonance box of the cavity between ceramic tile and body of wall, sound wave resonance, send the principle of the sound, in the middle of detecting floor or wall, the cavity is arranged, display buffer conversion sympathetic response frequency of sound wave, show the cavity size by display, have the hole on shell.
embodiment: after tile floor cavity detector startup, microprocessor produces exchange current, after note amplifier amplifies, drive the vibration head vibration of electroacoustic transducer, the vibration head vibration of electroacoustic transducer, ceramic tile is subjected to periodically to be used as forced vibration, if between ceramic tile and ground or between ceramic tile and body of wall, the cavity is arranged, between ceramic tile and ground or the cavity between ceramic tile and body of wall forms resonance box, send the sound, in the middle of detecting floor or wall, the cavity is arranged, acoustoelectric sensor is converted into electric current with the sound, after the A/D converter conversion, control the exchange current frequency that microprocessor produces, the exchange current frequency shift that microprocessor is produced, until sound wave resonance, display buffer conversion sympathetic response frequency of sound wave, show the cavity size by display, if there is no the cavity between ceramic tile and ground or between ceramic tile and body of wall, there is no sound wave resonance.
This detector detects between ceramic tile and ground or the cavity between ceramic tile and body of wall, simply, efficiently, householder and construction party are easily reached common understanding, be convenient to timely rectification, eliminate empty hidden danger, this detector provides foundation for relevant unit formulates house ornamentation flooring brick quality standard.
Although the above is described the preferred embodiments of the present invention by reference to the accompanying drawings; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away from the scope situation that aim of the present invention and claim protect, can also make the concrete conversion of a lot of forms, within these all belong to protection scope of the present invention.
