Abstract
The utility model discloses a novel master control device for a five-party talkback system. The master control device comprises a microprocessor signal processing module, an A/D converting module, and a D/A converting module, wherein the A/D converting module and the D/A converting module are connected with the microprocessor signal processing module. The master control device is characterized in that the D/A converting module is connected with a signal amplifying processing module used for amplifying a signal to recover audio data. The signal amplifying processing module is connected with a carrier transmitting module. Since the master control device is provided with the signal amplifying processing module, audio data can be recovered by performing signal receiving and decoding, digital-to-analog conversion, and signal amplification in order that a voice transmitting process is completed and further a communication signal is transmitted. Therefore, five-party talkback for an elevator is achieved and great convenience is provided for the reconstruction of the elevator.
Description
Technical field
The utility model relates to a kind of Intelligent elevator intercommunication system, particularly a kind of master control set of novel five side's intercom systems.
Background technology
The intercom system of traditional elevator, adopt analog, speech quality is poor to be easily disturbed, Digital Signal Processing is expensive, and detection failure bothers, complex circuit, be difficult to meet the requirement that user uses, although prior art Patent number is 201020209911.2, a kind of master control set of five side's intercom systems is disclosed, the processor communication module and the A/D modular converter that comprise intercommunication microprocessor and be connected with intercommunication microprocessor, be connected with carrier communication module on described A/D modular converter; When it uses, by the 36V power supply of elevator, as carrier, directly D/A modular converter connects carrier wave sending module and sends by and then transmit communication signal, thereby realizes five side's intercommunications of elevator.In master control set due to this five side's intercom systems, lacked a kind of signal amplification module, in actual use procedure, do not had signal to amplify processing, direct-reduction voice data, causes speech communication unintelligible.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of transmission master control set of novel five side's intercom systems clearly of simple in structure, voice.
The utility model solves the technical scheme that its technical problem adopts: a kind of master control set of novel five side's intercom systems, the A/D modular converter that comprises microprocessor signals processing module and be connected with microprocessor signals processing module, D/A modular converter, described A/D modular converter connecting communication signal collection module, described communication signal collection module connects the carrier receiving module for collecting audio signal, it is characterized in that: described D/A modular converter connects the signal amplification processing module of amplifying reduction voice data for signal, described signal amplifies processing module and connects carrier wave sending module.
The utility model adopts above technical scheme, compared with prior art has following technique effect:
Amplify processing module because the utility model has increased signal, can use the 36V power supply of elevator as carrier, audio signal is collected, changed, is compressed into digital signal, be sent to far-end by carrier wave; By receiving signal decoding, digital-to-analogue conversion, signal amplification reduction voice data, complete the transmittance process of voice and then transmit communication signal, thereby realizing five side's intercommunications of elevator, for the transformation of elevator provides great convenience again.
Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1, a kind of master control set of novel five side's intercom systems, the A/D modular converter (2) that comprises microprocessor signals processing module (1) and be connected with microprocessor signals processing module (1), D/A modular converter (3), described A/D modular converter (2) connecting communication signal collection module (6), described communication signal collection module (6) connects the carrier receiving module (4) for collecting audio signal, it is characterized in that: described D/A modular converter (3) connects the signal amplification processing module (7) of amplifying reduction voice data for signal, described signal amplifies processing module (7) and connects carrier wave sending module (5).
Operation principle of the present utility model: communication signal is collected audio signal by carrier wave receiver (4), communication signal collection module (6) does preliminary treatment to signal, deliver to microprocessor signals processing module (1) through A/D modular converter (2), after processing, then do D/A modular converter (3) conversion.Amplify the amplification of processing module (7) signal through signal and sent by carrier wave sending module (5), realize the transmission of audio signal.The utility model is directly connected with machine room main frame, car handset, sedan-chair holder machine, base station handset and pit handset while use, can use the interchange 36V of elevator or 220V power supply as carrier, and then transmission communication signal, thereby realize five side's intercommunications of elevator, due to simple in structure, volume is small and exquisite, secondary is constructed without rewiring, can save ample resources, for the transformation of elevator provides great convenience.
