Description
Technical field
The utility model relates to a kind of reisilometer, particularly a kind of voice digital display reisilometer.
Background technology
Concrete crushing strength is an important component index of construction engineering quality, it is the most popular a kind of method of concrete crushing strength that detects in the Non-Destructive Testing that rebound method detects concrete crushing strength, existing digital rebound tester is to increase displacement transducer on the basis of former mechanical reisilometer, mechanical rebound value is converted to digital signal, be convenient to the record and the processing of rebound value data, the data of rebound value and result are generally all exported by display screen or printer.During measurement, because concrete structural surface is uneven or have other defective, may cause and collect wrong rebound value, therefore the operator needs view screen demonstration at any time to judge the validity and the authenticity of rebound value when measuring, rebound method detects the measurement of concrete crushing strength need gather a large amount of rebound value data, often a member may reach dozens or even hundreds of measurement point, and measuring the place often is at the construction field (site), the operator whenever carries out one-shot measurement and wants view screen to check rebound value, like this, bring huge labour intensity to the operator undoubtedly, reduce detection efficiency, and meeting scatter operation person's notice, can not observe the variation of surrounding environment at any time, therefore also have certain risk, display screen also can be subjected to ambient light effects in addition, is difficult for observing under darker or brighter environment.Existing digital reisilometer all is to indicate rebound value and prompting error message with display screen, and in use the operator need check at any time that screen is to observe measured value.
Therefore, providing a kind of simple in structure, reasonable in design, dependable performance, voice digital display reisilometer easy and simple to handle is one of this those skilled in the art's problem demanding prompt solution.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of simple in structure, reasonable in design, dependable performance, voice digital display reisilometer easy and simple to handle are provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of voice digital display reisilometer, and it is characterized in that: this reisilometer comprises mechanical reisilometer and main frame; Described main frame comprises host shell and control circuit part, and described host shell is arranged at mechanical reisilometer top, and described host shell upper surface is respectively equipped with display screen, control button, is provided with loudspeaker simultaneously; Described control circuit partly comprises singlechip microprocessor, and the control circuit part is connected with power supply; Described singlechip microprocessor is connected storage, display screen, digital audio controller, sensor circuit respectively, and is connected with the control button; Described digital audio controller connects audio-frequency power amplifier, and described audio-frequency power amplifier is connected with loudspeaker.
The beneficial effects of the utility model are: the utility model has increased voice suggestion and miscue warning function at the host computer control circuit of existing digital rebound tester, adopt the mode of voice to play back rebound value, the operator need not to watch display screen can learn rebound value when measuring, and can set the measurement range of rebound value, when rebound value goes beyond the scope then with the mode play cuing error message of voice, with the compressive strength of accurate detection concrete component.It is simple in structure, reasonable in design, effectively improves detection efficiency, and reduces operator's labour intensity.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model control circuit module connection diagram;
Among the figure: 1 host shell, 2 mechanical reisilometers, 3 loudspeakers, 4 display screens, 5 buttons.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structural drawing, feature that foundation the utility model provides:
As shown in Figure 1, the utility model comprises host shell 1, and described host shell 1 is arranged at mechanical reisilometer 2 tops, and described host shell 1 upper surface is respectively equipped with host display 4, host computer control button 5, is provided with loudspeaker 3 simultaneously.
As shown in Figure 2, the utility model control circuit comprises singlechip microprocessor, described control circuit part is connected with power supply, and singlechip microprocessor is connected storage, display screen, digital audio controller (audio frequency DAC), sensor circuit respectively, and is connected with host computer control button 5; Described digital audio controller connects audio-frequency power amplifier, and described audio-frequency power amplifier is connected with loudspeaker 3.
The utility model is the controller control voice output of utilizing in the control circuit.Power supply adopts the 3.6V lithium battery to power, low pressure difference linear voltage regulator (LDO) power supply voltage stabilizing chip voltage stabilizing through 3.3V is that control circuit is powered to 3.3V, the singlechip microprocessor of control circuit can adopt AT91SAM7S64 as master controller, storer adopts SPI serial flash storer AT45DB161 stored sound data and rebound value data, AT91SAM7S64 is not owing to there is inner DAC, therefore adopt outside UDA1341 audio frequency DAC output sound waveform, AT91SAM7S64 exports with fixing sampling rate voice data by 12S interface control UDA1341 magnitude of voltage, and through audio-frequency power amplifier LM4890 amplification, output in the loudspeaker 3 on the host shell 1 and export voice, display screen 4 and button 5 are by the universal I/O port control of AT91SAM7S64, as man-machine interface, show the measurement parameter that rebound value information is relevant with input.Voice data is to be recorded and transferred to binary file by speech synthesis software, communication interface by the host computer control circuit is saved in the storer, the rebound value data of AT91SAM7S64 receiving sensor circuit conversion, and rebound value come out with speech play, if rebound value surpasses the alarming value that is provided with in the main frame, then play the alarm voice of " going beyond the scope ", the current rebound value of prompting operation person is invalid.Change the content of alarm voice if desired, only need synthetic speech file again, by the speech data in the communication interface updated stored device of main frame, the easily upgrade job of voice suggestion content in the future.
This reisilometer also can directly adopt the single-chip microcomputer in the digital rebound tester governor circuit, external finished product speech chip or directly output pwm signal convert the digital signal of voice to simulated audio signal through low-pass filter, amplify sound signal by note amplifier again, by loudspeaker plays; Also can be provided with external receiver J-Horner in addition, conveniently when noisy environment, utilize earphone to monitor.
Above-mentionedly this voice digital display reisilometer is described in detail with reference to embodiment, be explanation rather than limit, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
