Description
Technical field
The utility model relates to a kind of drive recorder, and refering in particular to is the drive recorder being with voice arousal function.
Background technology
Along with the raising of living standards of the people, automobile quantity gets more and more, and having private car has been very usual thing.Along with increasing of vehicle, running situation becomes increasingly complex, drive recorder accept by increasing people and use.Drive recorder can by the image in recording function record driving process and sound.But drive recorder in the market is still adopted and is manually carried out alternately, and this is very inconvenient when driving a vehicle driving, and can increase danger.If use the mode of interactive voice, people and machine picture are talked between men, then can be many safely.Even if but use interactive voice mode, still need to arrange button on equipment, wake speech recognition system up by this button, this still needs manual operation, still there is potential safety hazard.
Utility model content:
In order to overcome the shortcoming of prior art, the utility model provides a kind of drive recorder with voice arousal function.
The technical solution adopted in the utility model is: a kind of drive recorder with voice arousal function, this drive recorder has speech identifying function, this drive recorder also comprises voice wake-up module, voice wake-up module comprises the voice collecting unit for gathering user speech, its output terminal one tunnel is directly connected with the input end of the main control unit treating Rouser, A/D converter is passed through successively in another road, voice recognition unit is connected with the input end of main control unit, A/D converter is passed through successively in another road, voice recognition unit is connected with the input end of main control unit, the output terminal of main control unit respectively with voice recognition unit, the input end of A/D converter is connected, the analoging sound signal of input end is converted to digital signal by AD converter, and output to main control unit by voice recognition unit.
Further, described voice collecting unit is made up of the microphone for gathering user speech, note amplifier and comparer, the output terminal of microphone is connected with the input end of note amplifier, and the output terminal of note amplifier is connected with the output terminal of A/D converter with comparer respectively.
Further, main control unit and voice recognition unit complete by acp chip, and this acp chip model is that NT96650 chanted by connection.
The utility model has the advantage of: this device is in all functions with drive recorder itself and speech identifying function basis, provide the function directly waking sound identification module up without the need to button voice and therefore can realize interactive voice completely, no longer need manual operation.
Accompanying drawing explanation
Fig. 1 is wake module structured flowchart of the present utility model;
Fig. 2 is the utility model one-piece construction block diagram;
Fig. 3 is the utility model acp chip NT96650 structure.
Embodiment
The utility model is further illustrated below in conjunction with accompanying drawing and specific embodiment.
The utility model increases voice wake-up module on drive recorder (drive recorder has speech identifying function), comprise the voice collecting unit 2 for gathering user speech, its output terminal one tunnel is directly connected with the input end of the main control unit 1 treating Rouser, another road is successively by A/D converter 3, voice recognition unit 4 is connected with the input end of main control unit 1, another road is successively by A/D converter 3, voice recognition unit 4 is connected with the input end of main control unit 1, the output terminal of main control unit 1 respectively with voice recognition unit 4, the input end of A/D converter 3 is connected, as shown in Figure 1.The analoging sound signal of input end is converted to digital signal by AD converter 3, and outputs to main control unit 1. by voice recognition unit 4
As shown in Figure 1, described voice collecting unit 2 is made up of the microphone for gathering user speech, note amplifier and comparer, the output terminal of microphone is connected with the input end of note amplifier, and the output terminal of note amplifier is connected with the output terminal of comparer with A/D converter 3 respectively.The sound signal that microphone exports is amplified by note amplifier; Comparer has specific threshold values, this threshold values can regulate according to distinct device, varying environment, when the input voltage of comparer and the voice signal of microphone conversion are higher than threshold values, then the output terminal of comparer exports wake-up signal, is waken up by main control unit 1.Can carry out after waking up operating with sound identification module.
As shown in Figure 3, acp chip model is that NT96650 chanted by connection, comprises voice wake-up module, sound identification module and control module.
Claims (3)
1. the drive recorder with voice arousal function, this drive recorder has speech identifying function, it is characterized in that: this drive recorder also comprises voice wake-up module, voice wake-up module comprises the voice collecting unit (2) for gathering user speech, its output terminal one tunnel is directly connected with the input end of the main control unit (1) treating Rouser, another road is successively by A/D converter (3), voice recognition unit (4) is connected with the input end of main control unit (1), another road is successively by A/D converter (3), voice recognition unit (4) is connected with the input end of main control unit (1), the output terminal of main control unit (1) respectively with voice recognition unit (4), the input end of A/D converter (3) is connected, the analoging sound signal of input end is converted to digital signal by AD converter (3), and output to main control unit (1) by voice recognition unit (4).
