The data storage module 3 receives and stores the recorded video and/or the corresponding fault document, and it should be noted that the data storage module 3 supports external reading so as to transmit the stored information to the external device 5.
The data transmission module 4 communicates with the external device 5 and transmits the recorded video and/or the corresponding fault file stored in the data storage module 3 to the external device 5.
In an alternative embodiment, the system further comprises an interaction module 2 for supporting the user to enter the meter menu interface to turn on/off the meter information storage, and if so, further select the stored format as video or document or even select. Specifically, the interaction module 2 is in communication with the full liquid crystal instrument 1, and is used for selecting to turn on or off the instrument alarm information storage function in the menu page of the full liquid crystal instrument 1, and is also used for selecting the instrument alarm information storage format if the instrument alarm information storage function is selected to turn on.
The instrument alarm information storage format comprises a video, a document and a video plus document, wherein when the video is configured as the video, only the recorded video is stored, when the document is configured as the document, only the fault document is stored, and when the video plus document is configured, the recorded video and the fault document are simultaneously stored.
Accordingly, in this alternative embodiment, the full liquid crystal meter 1 responds to the occurrence of a meter alarm fault of the vehicle, judges whether the meter alarm information storage function is turned on, if so, detects the currently configured meter alarm information storage format, records the currently displayed image of the full liquid crystal meter 1 in the form of video, and then stores the recorded video and/or the corresponding fault document in the data storage module 3 based on the meter alarm information storage format.
For further understanding of the present invention, a detailed description of the present invention is provided below, and fig. 2 is a schematic diagram illustrating the working principle of the detailed embodiment.

If the instrument alarm information storage function is started and the instrument alarm information storage format is configured as a video+document, when an instrument fault alarm occurs, the instrument main control MCU sends a request instruction to the instrument display MCU, the instrument display MCU starts an application program to store the current display effect of the liquid crystal display in a fixed frame mode, video format data are automatically generated and transmitted to the instrument main control MCU, meanwhile, the received message data are returned to the instrument main control MCU again, the instrument main control MCU together with the message data are transmitted outside the instrument main control MCU, a document is formed by referring to a given template, and the video and the document are stored in the data storage module 3 after being configured with time scales.
The data storage module 3 and the full liquid crystal instrument 1 can be connected by using an SPI bus to support the insertion of SD cards with different memory sizes, and when the instrument main control MCU receives the returned video data, the instrument main control MCU can immediately communicate with the SD card to write the video data and the document into the SD card.
The data transmission module 4 may be a communication module of the full liquid crystal instrument 1, for example, a bluetooth/WIFI module or a communication line connection with a USB port of a vehicle, when data extraction is required, the external device 5 may establish connection with the full liquid crystal instrument 1 through a bluetooth/WIFI/USB manner, and after connection is successful, a file selected on an instrument menu page may be sent. The external device 5 is a device supporting bluetooth/WIFI/USB transmission, and may be a mobile terminal such as a mobile phone, a tablet, a computer, and the like.
The method is characterized in that an actual scene is used for describing, an air pressure sensor signal of an automobile is directly connected to an instrument, when the frame loss of an outgoing air pressure message is caused by factors such as an excessively high load rate of the instrument, an ABS/EBS controller judges that the braking air pressure is insufficient due to the fact that the received air pressure signal is lost, and when the frame loss condition exceeding a certain period occurs, the ABS/EBS controller judges that a braking system fails and sends the braking system to the instrument for indication. The driver can select the function of 'fault alarm storage' of an instrument menu page, select 'on', further select the storage format of 'video+document', in the following driving process, the display interface and the receiving and transmitting message of the instrument during alarm can be recorded and transmitted to the SD card by the instrument main control MCU, at the moment, the driver only needs to operate the multifunctional steering wheel key again, enter the setting interface, open the WIFI switch, connect a personal mobile phone hotspot, then enter the file storage interface, select two newly recorded files, click and transmit the files, and the files can be transmitted to the mobile phone in a WiFi mode. For the driver, the after-sales personnel do not need to wait for the real vehicle test, the file stored on the mobile phone is remotely sent to the after-sales personnel, for the after-sales personnel, the driver is not required to inquire other conditions except for an ABS/EBS fault alarm symbol of an instrument panel, if an instrument information storage function is started, display information during instrument alarm can be recorded, the instrument barometer can be always displayed normally through a video file, the fault of the air pressure sensor is eliminated, the video + document time line is compared, when the ABS/EBS fault alarm symbol appears in the instrument, the air pressure value is lost in the instrument outgoing air pressure message, so that the ABS/EBS fault alarm caused by the frame loss condition of the instrument outgoing air pressure message can be judged, an alarm source is found, and the air pressure frame loss problem is further solved.
