Abstract
The utility model relates to an external device used for an emergency vehicle body. The external device comprises a controller, a signal transceiver used for receiving a smashup signal and a communication module used for realizing communication with the outside, wherein the output end of the signal transceiver and the control end of the communication module are connected with the controller, and the communication module is also connected with a speaker. The external device provided by the utility model is capable of sending a rescue request when an accident happens.
Description
Technical field
The utility model relates to the mobile unit technical field, particularly relates to a kind of car machine external device that is used to meet an urgent need.
Background technology
In recent years; Automobile consumption becomes a big consumption hot spot; The recoverable amount of China's automobile is soaring year by year; The fast development of car industry itself has driven the development supporting, service industry of being correlated with, and automobile develops to multifunctional direction as the simple function of pure walking-replacing tool, satisfies people to the automobile multiple demands.
When automobile bumps, when collision is very serious, will cause the communication equipment of automotive interior to damage, thereby can't send aid request, cause and can't realize rescue in the very first time, possibly cause the loss of lives and properties.
The utility model content
The utility model technical problem to be solved provides a kind of car machine external device that is used to meet an urgent need, and can when accident takes place, send aid request immediately.
The utility model solves the technical scheme that its technical problem adopted: a kind of car machine external device that is used to meet an urgent need is provided, comprises controller, also comprise the signal transceiver that is used to receive the collision signal, be used for the communication module of communicating by letter with extraneous realization; The output of said signal transceiver links to each other with controller with the control end of said communication module; Said communication module also links to each other with loud speaker.
Be connected with audio-frequency power amplifier between said communication module and the loud speaker.
Said communication module also links to each other with audio input device.
Link to each other through universal asynchronous coffret between said signal transceiver and the controller.
Said signal transceiver is the CAN bus transceiver.
Said communication module is the 3G module.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art; Have following advantage and good effect: the utility model can make the work of car machine external device relatively independent through on car machine external device, increasing loud speaker, in case of emergency can realize rescuing function better; Even the loud speaker on the car damages, still do not influence telephony feature.
Description of drawings
Fig. 1 is the block diagram of the utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The utility model relates to a kind of car machine external device that is used to meet an urgent need, and is as shown in Figure 1, comprises controller, also comprises the signal transceiver that is used to receive the collision signal, is used for and the extraneous communication module of communicating by letter of realizing; The output of said signal transceiver links to each other with controller with the control end of communication module; Said communication module also links to each other with loud speaker.Wherein, the collision signal that sends according to signal transceiver of controller is controlled communication module and is realized that communication connects.
Link to each other through universal asynchronous coffret between said signal transceiver and the controller, asynchronous serial communication interface can convert the outside serial data of coming of computer into byte, supplies computer-internal to use the device of parallel data to use.In the serial data stream of output, add parity check bit, and the data flow that receives from the outside is carried out parity check.In output stream, add the start and stop mark, and from receiving data stream deletion start and stop mark, also can handle the interrupt signal (keyboard and mouse also are serial devices) sent by keyboard or mouse and the management by synchronization problem of process computer and external series equipment.
Signal transceiver is the CAN bus transceiver, and communication module is the 3G module.Because the integrated physical layer and the data link layer functions of CAN agreement can be accomplished the framing of communication data is handled in the CAN bus communication interface, comprise that position fillings, data block coding, cyclic redundancy check, priority discrimination etc. work.Therefore the collision signal that adopts the CAN bus transceiver when collision happens, can provide through the CAN bus at once learns that serious collision has taken place vehicle.Adopt the 3G module as communication module; Make and take place to support high speed data transfer after the car accident; Can transmit sound (conversation) and data message (Email, instant messaging etc.) simultaneously; Thereby more smooth in the time of can guaranteeing to converse, avoid the generation of situation such as suspension, thereby cause the delay of rescue time.Wherein, the 3G module can link to each other through the UART Interface and Controler, thereby is controlled the control of device.
Be connected with audio-frequency power amplifier between said communication module and the loud speaker,, drive loud speaker and send bigger sound, make the user can more clearly hear sound through the sound output that audio-frequency power amplifier can improve communication module is set.Drive loud speaker through audio-frequency power amplifier and send bigger sound, thereby guarantee that the user can hear the feedback information that attending a banquet of call center sent.Said communication module also links to each other with audio input device (like microphone); Through connect on the communication module microphone make the user can and the attending a banquet of call center between exchange; So can help the mood of user's keeping tensions down anxiety, for the user who is in panic state best timely rescue scheme is provided simultaneously.
After car accident took place, the workflow of the utility model was following:
At first, the CAN bus detects at once car accident has taken place, and is converted into the collision signal, sends to the CAN bus transceiver.
Then, after the CAN bus transceiver is received the collision signal, through asynchronous transmission interface notification controller.
Then, after controller is received the collision signal, put through phone with relief 3G module.
At last, after the 3G module was put through phone, the audio signal of output conversation through audio frequency power amplifier, drove the loud speaker sounding, makes the user can hear the sound of attending a banquet of call center.This shows that when associated components damaged in car, the car machine external device that is used to meet an urgent need still can be transferred to emergency call, and play voice.
If microphone does not damage in the car, can also car owner's sound be seen off, exchange with attending a banquet of call center.
This shows that the utility model can make the work of car machine external device relatively independent through on car machine external device, increasing loud speaker, in case of emergency can realize rescuing function better,, still do not influence telephony feature even the loud speaker on the car damages.
