Description
Technical field
The present invention relates to a kind of elevator MP 3 phonetic device in the cabin elevator.
Background technology
Now, cabin elevator all is widely used in the various skyscrapers in the city, the indispensable action instrument of its people that become at high-rise live and work.Meanwhile, people are to also having higher requirement to elevator, except needs good take environment, also need the automation service that puts in place.
At present, most of elevators can only lean on the floor indicator in the car to show floor information, when arriving, elevator can only carry out simple auditory tone cues, tonequality is relatively poor, in some high-grade hotels or office building, need often the voice messaging of elevator is upgraded, implement also cumbersomely now, and mood can be more boring when special floor is higher during passenger's using escalator.
Summary of the invention
The present invention is directed to the problem that exists in the background technology and propose a kind of elevator MP 3 phonetic device.
Elevator MP 3 phonetic device of the present invention, its structure comprises: micro controller system, SD storage card, CAN modular converter, MP3 decoding device, D and A converter and audio output device, wherein: the CAN bus is input to micro controller system by the CAN modular converter, the SD storage card connects micro controller system, micro controller system is connected with audio output device after being connected in series MP3 decoding device and D and A converter successively, and the parallel signal input end of micro controller system is used for importing parallel signal; Described micro controller system also is connected with a serial interface; Described audio output device comprises a power amplifier.
Memory capacity of the present invention is by SD memory card capacity decision, and the user can satisfy the demand of different situations with PC voice messaging data in the neocaine more very easily; The present invention also is applicable to the serial elevator control of CAN bus, and the good and volume of output tonequality can be digital regulated, and volume is little, and is simple in structure, easy for installation.
Description of drawings
Fig. 1 is the structural representation of elevator MP 3 phonetic device of the present invention.
The specific embodiment
As shown in Figure 1, elevator MP 3 phonetic device of the present invention, its structure comprises: single-chip microprocessor MCU (8051), SD storage card, CAN modular converter, MP3 decoding device, D and A converter and audio output device, wherein: the CAN bus is input to micro controller system by the CAN modular converter, the SD storage card connects micro controller system, micro controller system is connected with audio output device after being connected in series MP3 decoding device and D and A converter successively, and the parallel signal input end of micro controller system is used for importing parallel signal.
Described micro controller system also connects a RS232 serial interface, and described audio output device also comprises a power amplifier, and power amplifier is connected with loud speaker or PC audio amplifier.The present invention adopts high-quality MP3 decoding device and power amplifier, the good and scalable of tonequality; Adopt the SD storage card, the user can select memory capacity according to actual needs and can realize the renewal of voice messaging data in the card by PC; The present invention possesses CANbus and two kinds of serial interfaces of RS232 and a parallel input interface, and communication modes is adjustable, and during the elevator operation, elevator control panel imports the elevator operating data into this device by the serial or parallel input and carries out voice suggestion; The present invention can carry out not only that elevator is called out the stops and the prompting of service direction, can also play background music and advertisement and prompt messages.
