Summary of the invention
The object of the present invention is to provide a kind of elevator intelligent voice system that automatically carries out speech recognition, system can be identified passenger's phonetic control command, and according to phonetic order operation, has realized the intellectuality of voice system.
The present invention is achieved through the following technical solutions: a kind of intelligent elevator voice system, comprise microprocessor, and the read out instrument being connected with microprocessor respectively, voice device and logical device device, described logical device device is also connected with sound signal power amplifier, described microprocessor is also connected with isolated system, and isolated system is also connected with respectively automatic speech recognition system and floor key input system.The present invention sets up automatic speech recognition system on existing elevator voice system, during automatic speech recognition system is mainly used in exchanging with passenger's simple language in intelligent elevator voice system, passenger is wanted to the identification of the key message of arrival floor, further realized the intelligent management of elevator voice system.The Main Function of microprocessor is to control floor according to user profile and system information, and in read out instrument, shows corresponding information, and by floor information, the form with voice sends out by sound signal power amplifier.Read out instrument is mainly used in floor information, advertisement, the demonstration of the information such as notice.Voice device is mainly the form voice data with speech memory, and speech data comprises advertisement, notice, and music etc., and can realize amplification internal memory.Isolated system Main Function is that the elevator system signals to gathering is carried out interference protection processing, and the interference of prevention external circuit to collection signal guaranteed that information exchange crosses the acoustical quality of sound signal power amplifier.Because the microprocessor in existing intelligent elevator voice system, read out instrument, voice device and sound signal power amplifier belong to mature technology, and improvement of the present invention does not lie in microprocessor, read out instrument, voice device and sound signal power amplifier, therefore not in the structure and the principle of work that repeat microprocessor, read out instrument, voice device and sound signal power amplifier.
Further, described microprocessor is AT89C51 micro controller system.
Further, described read out instrument is LCD LCDs.
Further, described voice device is speech memory.
Further, described logical device device is connected with microprocessor with speech memory respectively.
Further, described logical device device is connected with microprocessor with speech memory respectively.Signal information through microprocessor processes drives read out instrument work, and speech memory is carried out to read-write operation, by the voice data transmission of memory device to sound signal power amplifier, sound signal power amplifier comprises demoder, power amplifier actuator and the loud speaker of series connection successively, and described demoder is also connected with logical device device.Speech data is decoded through demoder, demoder can convert memory device MP3 format data encoding to digital audio and video signals, and send A and D converter to, and A and D converter is converted to analog signal by digital audio and video signals, and final simulated audio signal drives loud speaker to sound by power amplifier.
Further, between described isolated system and microprocessor, be provided with radio transmitting device.Described radio transmitting device is GPRS radio transmitting device.Radio transmitting device comprises sending end and receiving end, and described sending end is connected with isolated system, and described receiving end is connected with microprocessor.Floor information and automatic speech recognition information that signal acquiring system gathers, enter after isolated system processes, and through sending end, is sent to microprocessor, and the receiving end of microprocessor receives, and will carry out next step information comparison and analyze.
The present invention, except setting up radio transmitting device, reduces the not convenient property of wired installation, reduces use cost, and in input media, has increased automatic speech recognition system, has realized the further intellectuality of elevator voice system.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) the present invention is by setting up automatic speech recognition system, and elevator passenger, can selection key or the form input object floor information of voice in exchanging with voice system, has further improved the reliability of elevator voice system, intellectuality.
(2) the present invention adopts radio transmitting device to substitute reception and transmission that traditional cable data transmitting device carries out signal, so effective saving adopts wired use cost, and improved equally accuracy and the reliability of data transmission, also avoided wire transmission to carry out the not convenient property of wired installation.

Fig. 1 is the structural representation block diagram of the embodiment of the present invention 1.
Fig. 2 is the structural representation block diagram of the embodiment of the present invention 2.
The specific embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1:
The principle of the present embodiment, as shown in Figure 1, a kind of intelligent elevator voice system, comprise microprocessor, and the read out instrument being connected with microprocessor respectively, voice device and logical device device, described logical device device is also connected with sound signal power amplifier, and described microprocessor is also connected with isolated system, and isolated system is also connected with respectively automatic speech recognition system and floor key input system.Described microprocessor is AT89C51 micro controller system, described read out instrument is LCD LCDs, voice device is speech memory, described sound signal power amplifier comprises demoder, power amplifier actuator and the loud speaker of series connection successively, described demoder is also connected with logical device device, and described logical device device is connected with microprocessor with speech memory respectively.Take certain high building elevator device is example, when passenger arrives 9th floor, destination from Stall, enter after elevator, voice system starts to inquire that passenger will arrive the floor information of destination, passenger can select by the key-press input of control panel in elevator or phonetic entry, now, the button of 9th floor, arrival floor shown in red.Elevator signal acquisition system is by automatic collection signal, send isolated system to, prevent that external circuit signal is to interference such as acoustical qualities, information after treatment sends microprocessor to, after information comparison and analyzing, send control command, one, drive read out instrument to show the floor arriving, read out instrument can show the information such as advertisement, notice, date, weather between demonstration contiguous floors interval.Its two, carry out voice and report and submit, the communication of microprocessor processes is to logical device device, on the one hand speech memory carried out to read-write operation, on the other hand the information of speech memory is sent to demoder and decodes.Because sound signal power amplifier is the state of the art, and improvement of the present invention do not lie in sound signal power amplifier, and those skilled in the art can draw the working process of sound signal power amplifier by common practise.Therefore do not indicate in detail in Fig. 1, it does not illustrated in detail yet.
