Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Fig. 2 shows a schematic diagram of a hardware structure of the car machine system, and as shown in fig. 2, the car machine system includes a bluetooth chip and a car-mounted voice system, and the car-mounted voice system includes a DSP (Digital Signal Processing) chip, a microphone, an amplifier, and a speaker, and is configured to implement a wireless communication function through the bluetooth chip. The microphone is used for collecting the sound of people in the vehicle, the collected sound is sent through the Bluetooth chip after being processed by the DSP chip, and signals received by the Bluetooth chip are processed by the DSP chip and are played and output by the loudspeaker after being amplified by the amplifier.
In the prior art, a detection method for a car machine generally needs a detection person to hold external communication equipment such as a smart phone with a bluetooth function, and a connection path can be established through a series of tedious screen operations, and then a phone and the car machine are used for dialing and communicating to detect whether the car machine communication is normal or not. This approach has the following disadvantages:
firstly, the time cost for programming the car machine program is too high. The successful connection of the car Machine and the mobile phone Bluetooth on a production line is realized, at least program packages which can enable the Bluetooth module, the audio module, the HMI (Human Machine Interface) Interface and the like to normally work are required to be burned on the car Machine.
Secondly, the operation flow of the detection personnel is complicated. During detection, detection personnel need to perform operations such as searching, pairing connection and the like on the HMI interface to enable the vehicle and the machine to be successfully connected with the mobile phone Bluetooth, so that the operations of the detection personnel are invisibly increased, the time cost is increased, meanwhile, the requirement on the quality of the operation personnel is high, and the labor cost is high.
Thirdly, the equipment and network costs are high. The existing detection method needs to use at least one mobile phone to perform connection test with the vehicle, thereby increasing the cost of purchasing the mobile phone. Furthermore, because the testing process requires a telephone call, mobile network signals are also required, and thus, the existing testing methods increase the cost of purchasing a handset and using a mobile network.
To above-mentioned problem, this application has provided a simple and convenient efficient car machine detection mode. As shown in fig. 1, a car machine detection method, wherein a car machine to be detected includes a bluetooth chip and a car-mounted voice system, the method includes the following steps:
step S110: and sending an instruction to a Bluetooth chip of the vehicle machine, and configuring the Bluetooth chip to work in a closed loop mode, so that the Bluetooth chip can directly send the audio signal acquired by the vehicle-mounted voice system back to the vehicle-mounted voice system without encoding.
Step S120: and inputting audio into a microphone of the vehicle-mounted voice system, and detecting whether the vehicle-mounted machine is normal or not by monitoring the playing condition of a loudspeaker of the vehicle-mounted voice system.
This application is closed loop mode through the bluetooth chip of configuration car machine, make the bluetooth chip can directly send the audio signal that on-vehicle voice system gathered back to on-vehicle voice system without encoding, thereby, make inside bluetooth chip and the on-vehicle voice system who takes certainly of car machine form closed loop structure (refer to shown in figure 2), audio signal is gathered to the microphone that directly passes through the car machine, and transmit the speaker of car machine and play, thereby, can once only accomplish the detection of bluetooth chip and the whole function of on-vehicle voice system, the flow is simple, high durability and convenient operation, high efficiency.
Compared with the prior art, the method has the advantages that the vehicle-mounted external call device (such as a mobile phone with a Bluetooth function) is detected, the device cost and interface operation of adding the mobile phone are saved, meanwhile, complicated programs such as networking communication and HMI interface control do not need to be burnt, the time cost of burning the program is saved, the method is more suitable for production line application, and the vehicle-mounted external call device can be detected as early as possible.
In an embodiment of the present application, in step S110, sending an instruction to a bluetooth chip of the vehicle, and configuring the bluetooth chip to operate in a closed-loop mode includes:
and sending a closed-loop instruction and a clock instruction to the Bluetooth chip to enable a PCM (Pulse Code Modulation) input end (PCM IN) and a PCM output end (PCM OUT) of the Bluetooth chip to be short-circuited IN a data transmission function.
Under a normal condition, after an SCO link of a Bluetooth call is established, voice input by a vehicle microphone is converted into an audio signal through a DSP chip and enters from a PCM IN, and processed data is sent out through a Bluetooth chip; and the mobile phone signal received by the vehicle-mounted receiver is output from the PCM OUT, and can be restored to be played from the loudspeaker of the vehicle-mounted receiver after being decoded by the PCM.
And the present application is a closed loop mode realized by setting the PCM mode of the bluetooth chip. Under the closed-loop mode, data do not pass through PCM coding and decoding of the Bluetooth chip, which is equivalent to short-circuit PCM IN and PCM OUT. Therefore, voice data collected by the car microphone enters from the PCM IN of the Bluetooth chip and is directly output from the PCM OUT, and the voice data flows to the loudspeaker of the car to be played to form a data closed loop structure, as shown by an arrow IN figure 2 of the application.
Referring to FIG. 2, in one embodiment of the present application, the components of the in-vehicle speech system include: microphone, speaker, DSP chip and amplifier (AMP for short). The microphone is connected with the PCM input end of the Bluetooth chip through the DSP chip; the loudspeaker is connected with the PCM output end of the Bluetooth chip through the amplifier and the DSP chip. From this, on-vehicle voice system and bluetooth chip form signal closed loop structure, and the audio frequency that car machine self microphone was gathered transmits for the amplifier through DPS chip and bluetooth chip, plays by the speaker then to need not to connect outside talking equipment and converse and detect, just can self realize voice detection, easy operation just saves a large amount of times of burning record, and complicated connection operation and cell-phone hardware, network cost.
In an embodiment of the present application, in order to improve the detection efficiency, it may be further configured to detect whether the closed-loop mode of the bluetooth chip is successfully configured after the closed-loop mode of the bluetooth chip is configured, and if the closed-loop mode of the bluetooth chip is not successfully configured, the detection is suspended, the problem is timely checked, and a test is performed separately after the problem is solved.
In the detection process, if the Bluetooth chip is successfully configured, the Bluetooth chip is proved to be normal, otherwise, the Bluetooth chip is proved to have problems for a long time. Because only when the bluetooth chip is normal, just can rely on the closed loop mode of bluetooth chip to realize car machine voice system's function detection, continue to carry out detection on next step, therefore, when detecting bluetooth chip configuration failure, direct diagnosis bluetooth chip self has the trouble, in time suspends the detection, gets rid of and carries out detection operation on next step again after the trouble of bluetooth chip, can improve work efficiency.
In an embodiment of the present application, if it is detected that the audio played by the speaker of the vehicle-mounted audio system is inconsistent with the audio input by the microphone, it may be suspected that the vehicle-mounted audio system has a fault, and thus, it may continue to detect whether each component of the vehicle-mounted audio system is normal, respectively, to eliminate the fault.
On the basis of successful configuration of the Bluetooth chip, the Bluetooth chip can be judged to be normal, and under the condition, if the problem that the audio played by the loudspeaker is inconsistent with the audio input by the microphone occurs, the problem exists in the vehicle-mounted voice system. Under normal conditions, voice signals collected by the microphone are transmitted to the loudspeaker through the closed loop and played and output by the loudspeaker, so that the same sound as the sound collected by the microphone is detected at the loudspeaker, if the same sound is not detected, the problem exists in a certain component in the vehicle-mounted voice system, and at the moment, whether the functions of all the components are normal or not can be continuously checked through the configuration modules configured to other components.
The application also discloses a car machine detection system, as shown in fig. 3 and 4. The car machine that is detected includes bluetooth chip and on-vehicle voice system, and this system includes: the device comprises an upper computer module, a control module and a configuration module.
And the upper computer module is used for sending a detection instruction to the control module.
And the control module is used for communicating with the upper computer module, receiving the detection instruction sent by the upper computer module, analyzing the detection instruction and sending the detection instruction to the corresponding configuration module.
And the configuration module is used for responding to the detection instruction sent by the control module, sending an instruction to the Bluetooth chip of the vehicle-mounted device and configuring the Bluetooth chip to work in a closed-loop mode, so that the Bluetooth chip can directly send the audio signal acquired by the vehicle-mounted voice system back to the vehicle-mounted voice system without coding, and whether the vehicle-mounted device is normal is detected by comparing the audio input by the microphone of the vehicle-mounted voice system with the audio played by the loudspeaker.
Each module of the vehicle detection system can be realized in a hardware or software mode. For example, the car machine detection system is realized by burning basic function software on a production line to a car machine and matching with an application program of an upper computer. Of course, the present application may also be embodied in the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
In an embodiment of the present application, the configuration module is specifically configured to: sending a closed-loop instruction and a clock instruction to the Bluetooth chip to enable a PCM input end and a PCM output end of the Bluetooth chip to be in short circuit in a data transmission function; the components of the vehicle-mounted voice system comprise: a microphone, a loudspeaker, a DSP chip and an amplifier; the microphone is connected with the PCM input end of the Bluetooth chip through the DSP chip; the loudspeaker is connected with the PCM output end of the Bluetooth chip through the amplifier and the DSP chip. Therefore, the vehicle machine forms a self closed loop system, and whether each component of the vehicle machine is normal or not can be diagnosed through one-time detection.
In an embodiment of the application, the configuration module is further configured to detect whether the closed-loop mode of the bluetooth chip is successfully configured after the closed-loop mode of the bluetooth chip is configured, and return a configuration result to the upper computer module through the control module; and the upper computer module is also used for displaying the configuration result of the Bluetooth chip. Therefore, when the detection personnel operate, the configuration result can be visually seen through the upper computer module, and when the Bluetooth chip fails to be configured, the Bluetooth chip fault can be diagnosed, so that the detection is stopped, and the vehicle machine is diagnosed to be a defective product for troubleshooting.
