Description of drawings
Fig. 1 is the circuit structure block diagram that the speech recognition counter is used in financial accounting described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to the instructions word to make those skilled in the art.
As shown in Figure 1, the utility model provides a kind of financial accounting speech recognition counter, the circuit main board that comprises housing and be positioned at enclosure interior, and described circuit main board comprises: processor; Voice receiver, it is arranged on the front of described housing; Voice recognition chip, it is connected with described voice receiver, receives the voice signal of described voice receiver, and described voice recognition chip is connected with described processor, to the voice signal of described processor transmission through identification; And 9 needle serial ports, it is connected with described processor, is arranged on a side of described housing.
Voice recognition chip described in the utility model adopts voice recognition chip LD3320, described voice receiver is connected with the microphone interface of described voice recognition chip LD3320, and the Parallel I of described voice recognition chip LD3320/O mouth, control port and interrupt output port are electrically connected to described processor.Described LD3320 chip is a special use " speech recognition " chip, its inner integrated voice recognition processor and some external circuits, comprise AD, DA converter, microphone input interface and sound output interface etc., can also by serial port or parallel port is connected with the host CPU of outside, the content of speech recognition be passed to host CPU carry out further work.In the utility model the utility model, voice recognition chip only need to be identified 10 arabic numeral and several of short duration voice and get final product, and at this moment, phonetic entry just can substitute original key-press input, comes operating buttons more convenient faster with voice.Certainly, the normal operation of voice recognition chip be kept, corresponding clock frequency must be provided, normal working voltage etc.
9 needle serial ports described in the utility model are connected with described processor by the level shifting circuit that the MAX232 chip forms.Serial ports is devices communicating agreement very general on computing machine, and large multicomputer all includes two based on the serial ports of RS-232.9 needle serial ports of the utility model design are the interfaces that counter and computing machine carry out the serial communication transmission, what it was used is RXD port (receiving port) and the TXD port (transmit port) of described processor, because the processor serial port level of routine is generally the Transistor-Transistor Logic level signal, and the signal that calculates the function reception is standard RS232 level, so when counter will carry out serial communication when reportedly defeated with computing machine, the conversion that must carry out level could be received by computing machine.
when the user sends the speech data information that will calculate by the voice receiver on described housing facing to counter, its inside is sent to speech recognition circuit the inside identification by the microphone interface of voice recognition chip, and the ASCLL code value of the voice signal after identifying is passed to described processor, processor receives signal and judges processing, the level shifting circuit that connects by its serial ports after processing converts the Transistor-Transistor Logic level of itself to level signal that the calculating function receives, needing this moment the serial ports of an external special use to turn the USB keyboard chord is connected with computing machine, this level signal just can be transferred on computing machine by the USB line of this root special use, briefly, the output signal of primary processor serial ports just converts the input of computer keyboard to and then is input to the current cursor position of computing machine.
Housing described in the utility model front also is provided with display screen and a plurality of function button, and described display screen and described a plurality of function buttons are inner has circuit to be connected with described primary processor.When the user did not adopt serial ports to turn the USB keyboard chord counter is connected with computer, the result of calculation of counter will show by display screen.Described a plurality of function button can comprise: power switch key, " transmission " button and " removing " button.When the user presses " transmission " button, the result of calculation of counter gained will send by the serial ports of described primary processor, the data message that sends carries out after the RS-232 level conversion serial ports by special use and turns the USB keyboard chord and send to the current cursor of computing machine position, and this special-purpose serial ports turns USB keyboard chord existing finished product on market, so the utility model obtains carrying out with computing machine 9 needle serial ports of data transmission by the design level shifting circuit, facilitated financial and accountancy personnel's work, work efficiency is provided simultaneously.When the user pressed " removing " key, the result of calculation on the counter display screen will be eliminated, and this is the same with the common counter of prior art.
Housing described in the utility model front also is provided with loudspeaker, and its inside is connected with the voice output interface circuit of described voice recognition chip.When the primary processor of counter is shown to computer display with result, also sends data message to described voice recognition chip by its voice output interface output by FPDP, and then report out by loudspeaker.
Circuit main board described in the utility model also is provided with power circuit, respectively to described voice recognition chip and the power supply of described processor.Because the normal working voltage of voice recognition chip is 3.3V, and processor is generally 5V, so must the designing power supply circuit satisfy the normal operation of two systems.
The speech recognition calculator structure described in the utility model is simple, only be provided with power switch button and a plurality of function button on housing, and there is no 0 to 90 original arabic numeral button, four kinds of simple operation buttons of "+" "-" " * " "/", these buttons that lack just can be realized by phonetic entry.
Speech recognition counter described in the utility model neither needs the user to carry out the manual operation keys of computer to obtain result of calculation, do not need the user that result of calculation is driven in computing machine the inside yet, only need a serial ports to turn the USB keyboard chord and just the serial ports output of counter can be converted to the keyboard input of computing machine, result of calculation is input to computing machine the inside, greatly improved the accuracy of calculating, save the working time, improved financial and accountancy personnel's work efficiency.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in instructions and embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
