The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.
Fig. 2 shows a schematic hardware structure of the car machine system, as shown in fig. 2, where 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, for implementing a wireless call function through the bluetooth chip. The microphone is used for collecting the sound of personnel in the vehicle, the collected sound is processed by the DSP chip and then transmitted by the Bluetooth chip, and the signal received by the Bluetooth chip is processed by the DSP chip and is amplified by the amplifier and then played and output by the loudspeaker.
In the detection method for the car and the machine in the prior art, a detection person is usually required to hold external communication equipment such as a smart phone with a Bluetooth function, a connection path can be established through a series of complicated screen operations, and then the car and the machine can be detected whether the communication is normal or not through dialing communication between the mobile phone and the car and the machine. This approach has the following disadvantages:
1. the time cost of programming the car loader is prohibitive. The bluetooth of the mobile phone is successfully connected to the car machine on the production line, at least a program package which can enable the bluetooth module, the audio module, the HMI (Human Machine Interface, human-computer interface) interface and the like to work normally needs to be burnt on the car machine, and because the required functions are complex, the volume of the program package is very large, the burning is needed for a long time, and the operation accidents are easy to occur.
2. The operation flow of the detection personnel is complex. During detection, detection personnel need to search, mate operation such as connect on the HMI interface, just can let car machine successfully connect mobile phone bluetooth, have increased detection personnel's operation intangibly, have increased time cost, and the quality requirement to operating personnel is higher simultaneously, and the human cost is high.
3. The equipment and network costs are high. The existing detection method needs to use at least one mobile phone to carry out connection test with the car machine, so that the cost for purchasing the mobile phone can be increased. Moreover, because the test procedure requires making a call, it is also required for mobile network signals, and thus, existing test methods increase the cost of purchasing handsets and using mobile networks.
Aiming at the problems, the application provides a simple, convenient and efficient vehicle-mounted machine detection mode. As shown in fig. 1, a vehicle detection method, wherein a vehicle to be detected includes a bluetooth chip and a vehicle-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: audio is input to a microphone of the vehicle-mounted voice system, and whether the vehicle is normal or not is detected by monitoring the playing condition of a loudspeaker of the vehicle-mounted voice system.
According to the method, the Bluetooth chip of the car machine is in a closed-loop mode, the Bluetooth chip can directly send the audio signals collected by the car voice system back to the car voice system without coding, so that the Bluetooth chip and the car voice system in the car machine form a closed-loop structure (shown in reference to figure 2), the audio signals are directly collected through the microphone of the car machine and are transmitted to the loudspeaker of the car machine to be played, the whole functions of the Bluetooth chip and the car voice system can be detected at one time, and the method is simple in flow, convenient to operate and higher in efficiency.
Compared with the prior art, the method has the advantages that the car machine is connected with external communication equipment (such as a mobile phone with a Bluetooth function) for detection, the equipment cost and interface operation for adding the mobile phone are omitted, meanwhile, complex programs such as network communication and HMI interface control are not required to be burnt, the time cost of the burning program is omitted, the method is more suitable for production line application, and car machine function detection can be completed early.
In one embodiment of the present application, in step S110, an instruction is sent to a bluetooth chip of a vehicle, and the bluetooth chip is configured to operate in a closed loop mode, including:
and sending a closed-loop instruction and a clock instruction to the Bluetooth chip, so that the PCM (Pulse Code Modulation ) input end (PCM IN) and the PCM output end (PCM OUT) of the Bluetooth chip are short-circuited IN a data transmission function.
Under normal conditions, after an SCO link of Bluetooth communication is established, voice input by a microphone of the car machine is converted into an audio signal through a DSP chip and enters from a PCM IN, and processed data is sent out through the Bluetooth chip; and the mobile phone signal received by the receiving end of the car machine is output from the PCM OUT, and the original sound can be restored to be played from the loudspeaker of the car machine after the PCM is decoded.
And the closed loop mode realized by setting the PCM mode of the Bluetooth chip. The data does not pass through the PCM codec of the Bluetooth chip IN the closed loop mode, which is equivalent to shorting the PCM IN and the 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, so that a data closed-loop structure is formed, and the data closed-loop structure is shown as an arrow IN an attached drawing 2 of the application.
Referring to fig. 2, in one embodiment of the present application, components of an in-vehicle voice system include: microphones, speakers, DSP chips and amplifiers (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. Therefore, the vehicle-mounted voice system and the Bluetooth chip form a signal closed loop structure, audio acquired by the microphone of the vehicle is transmitted to the amplifier through the DPS chip and the Bluetooth chip and then played by the loudspeaker, so that voice detection can be realized without connecting external communication equipment for communication detection, the operation is simple, a large amount of burning time is saved, and complex connection operation, mobile phone hardware and network cost are saved.
In one embodiment of the present application, in order to improve the detection efficiency, after the closed loop mode of the bluetooth chip is configured, whether the closed loop mode of the bluetooth chip is configured successfully or not may be detected, if not, the detection is stopped, the problem is timely checked, and after the problem is solved, another test is performed.
In the detection process, if the Bluetooth chip configuration is detected to be successful, the Bluetooth chip is proved to be normal, otherwise, the Bluetooth chip is proved to have a problem for a long time. Because only when the Bluetooth chip is normal, the function detection of the car machine voice system can be realized by means of the closed loop mode of the Bluetooth chip, and the next detection is continued, when the failure of the Bluetooth chip configuration is detected, the failure of the Bluetooth chip is directly diagnosed, the detection is stopped in time, and the next detection operation is carried out after the failure of the Bluetooth chip is eliminated, so that the working efficiency can be improved.
In one embodiment of the present application, if it is detected that the audio played by the speaker of the vehicle-mounted voice system is inconsistent with the audio input by the microphone, the vehicle-mounted voice system may be suspected to fail, so that whether each component of the vehicle-mounted voice system is normal or not may be continuously detected to discharge the failure.
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 of the vehicle-mounted voice system is described. Because under normal conditions, the voice signals collected by the microphone are transmitted to the loudspeaker through the closed loop, and the loudspeaker plays and outputs the voice signals, the same sound as the sound collected by the microphone should be detected at the loudspeaker, if the same sound cannot be detected, the fact that a certain component in the vehicle-mounted voice system has a problem is indicated, and at the moment, whether the functions of all the components are normal can be continuously checked through the configuration modules configured for other components.
The application also discloses a vehicle-mounted machine detection system, as shown in fig. 3 and 4. The detected car machine comprises a Bluetooth chip and a car-mounted voice system, and the system comprises: the system comprises an upper computer module, a control module and a configuration module.
The upper computer module is used for sending detection instructions to the control module.
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.
The configuration module is used for responding to the detection instruction sent by the control module, sending the instruction to the 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 collected by the vehicle-mounted voice system back to the vehicle-mounted voice system without coding, and whether the vehicle machine is normal or not can be 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 machine detection system can be realized in a hardware or software mode. For example, the system is realized by burning basic function software to the car machine on the production line, and the car machine detection system is realized by matching with an application program of the upper computer. Of course, the present application may also be embodied in the form of a computer program product that is embodied in 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 one 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, so that the PCM input end and the PCM output end of the Bluetooth chip are in short circuit in a data transmission function; the components of the vehicle-mounted voice system comprise: a microphone, a speaker, 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 all components of the vehicle machine are normal at the same time can be diagnosed through one-time detection.
In one embodiment of the present application, the configuration module is further configured to detect whether the closed loop mode of the bluetooth chip is configured successfully 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; 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 can be diagnosed, so that the detection is stopped, the vehicle machine is diagnosed as a defective product, and the fault is checked.
