Description
Technical field
The utility model relates to a kind of elevator voice system, particularly relates to a kind of elevator voice system with demoder.
Background technology
Along with the Chinese society expanding economy, the installation of elevator and usage quantity are more and more, elevator offers convenience to people's skyscraper of coming in and going out, and voice system is the indispensable part of elevator, is used for floor count off, direction prompting, warning bulletin, fire-fighting intercommunication and advertising etc.The traditional voice system is most to be adopted the speech-chips storage and plays voice, but exist such as peripheral circuit complexity, lower tone, cost is high, capacity is little and the defective such as the difficult change of voice.
Summary of the invention
The purpose of this utility model is that the elevator voice system with demoder that a kind of circuit is simple, acoustical quality good, cost is low is provided in order to address the above problem.
The utility model is achieved through the following technical solutions:
A kind of elevator voice system with demoder, comprise central process unit, logic processor, speech memory, demoder, power amplifier driving circuit and loud speaker, the signal input part of described central process unit is connected with button, the signal output part of described central process unit and the signal input part of described logic processor are connected signal input part and are connected with speech memory, the signal output part of described logic processor is connected with the signal input part of described demoder, the signal output part of described demoder is connected with the signal output part of described power amplifier driving circuit, and the signal output part of described power amplifier driving circuit is connected with the signal input part of described loud speaker.
Logic processor mainly is the CPLD that can carry out powerful data quick-processing.Can find out from whole system, treater need to respond input message and can drive display module work, also to carry out read-write operation to the memory device of expansion, and the speech data of memory device is delivered to demoder decode, central process unit only is responsible for sending control command, and concrete operations are to be finished by CPLD, have greatly improved speed and the reliability of system.MP3 or WAV format audio file enter demoder inside by the SDI bus, and decoding.After the decoding, data may be sent to bass and the high pitch optimizer carries out the audio processing.After this, data communication device is crossed volume control unit, backups to simultaneously among the audio frequency FIFO.Audio frequency FIFO keeps data, and as the input of sampling rate converter and DAC.
Further, the elevator voice system also comprises phonetic incepting module and phonetic decision module, the signal output part of described phonetic incepting module is connected with the signal input part of described phonetic decision module, and the signal output part of described phonetic decision module is connected with the signal input part of described central process unit.When entering the large-scale real estate market of writing, mainly be to inform floor and other the relevant information that the passenger will reach by the handler, draw together the phonetic incepting module and the phonetic decision module can in advance with in these Data Enter elevator voice systems, realize intellectuality and the automation of elevator voice by setting.
As preferably, described elevator voice system also comprises read-out, and the signal output part of described central process unit is connected with the signal input part of described read-out.
As preferably, described elevator voice system also comprises annunciator, and the signal input part of described annunciator is connected with the signal output part of described central process unit.
As preferably, described elevator voice system also comprises read-out, and the signal input part of described read-out is connected with the signal output part of described central process unit.
The beneficial effects of the utility model are:
Adopt technique scheme, the utility model adopts coder that the voice of exporting are sent to bass and the high pitch optimizer carries out the audio processing, so that acoustical quality improves greatly, in addition, the utility model has also that circuit is simple, cost is low and the advantage such as stable effect.
