[0019] A vehicle diagnostic method based on voice interaction includes the following steps:
[0020] S1: The operator starts the system by pressing the start button and inputting a voice command;
[0021] S2: The voice interaction device receives the voice information, and the micro-processing module adjusts the direction of the sound hole 4 according to the pronunciation position;

[0026] Preferably, the specific process of S2 is as follows:
[0027] S2-1: When the operator presses the start button, the telescopic rod extends and pushes the connecting plate, thereby causing the lifting cylinder to rise and expose the sound hole;
[0028] S2-2: When the voice interaction device receives the voice information, the microprocessor module controls the first steering motor to start and drive the first driving gear to rotate. Since the first gear ring and the first driving gear are engaged, the first bottom ring can be rotated to a corresponding angle, thereby adjusting the direction of the lifting cylinder so that the sound hole faces the direction of the operator.
[0029] Compared with the prior art, the present invention has the following beneficial effects:
[0030] The present invention proposes a vehicle-mounted diagnostic system and method based on voice interaction, which is provided with a vehicle body information collection module and multiple collection devices to facilitate the collection of various vehicle body data information such as vehicle speed, mileage, faults, alarms, etc., which is more comprehensive and safer; by providing a fault diagnosis module, the vehicle body data information can be quickly diagnosed to determine the vehicle condition information; by providing a display module and a touch panel, the vehicle condition information can be intuitively displayed; by providing a voice interaction module and a voice interaction device, commands can be issued and vehicle condition information can be broadcast by voice, which is more convenient and safer.
[0031] The voice interaction device in the present invention can automatically adjust the direction of voice transmission and reception according to the position of the user. When the voice interaction device receives voice information, the microprocessor module controls the first steering motor to start and drive the first drive gear to rotate. Since the first gear ring and the first drive gear are engaged and connected, the first bottom ring can be rotated to a corresponding angle, thereby adjusting the direction of the lifting cylinder so that the sound hole faces the direction of the operator, making it easier for the operator to hear and issue instructions.
[0032] After the device has been used for a long time, the sound hole is easily blocked by dust, affecting the clarity of voice reception and transmission. The second steering motor can be started through voice commands or touch screen input to drive the second driving gear. Because the second driving gear is meshing with the second gear ring, the second bottom ring can drive the inner cylinder to rotate half a circle, thereby aligning the movable plate and the sound hole. At this time, the block inside the lifting cylinder blocks the block rod, and the second steering motor continues to start to drive the second driving gear to rotate, so that the second steering motor itself can drive the motor mounting base to rotate, thereby rotating the bottom column, and the side panel rotates to a certain angle to compress the second airbag, and the gas in the second airbag enters the first airbag. The first airbag expands and stretches to push the movable plate, thereby causing the ejector pin to be inserted into the sound hole, which can push out the dust in the sound hole, and the device can be cleaned for easy use.

[0048] A microprocessing module is provided inside the voice interaction device.
[0049] The voice interaction device includes a mounting block 1, which is embedded and installed above the center console or other suitable position. The interior of the mounting block 1 is a hollow structure. A circular hole is provided on the top surface of the mounting block 1. A lifting cylinder 2 is provided inside the mounting block 1. The outer wall of the lifting cylinder 2 is tightly attached to the inner wall of the circular hole.

[0052] After the device has been used for a long time, the sound hole 4 is easily blocked by dust, affecting the clarity of voice reception and transmission. The second steering motor 20 can be controlled to start by voice command or touch screen input to drive the second driving gear 21. Because the second driving gear 21 is meshed with the second gear ring 19, the second bottom ring 18 can drive the inner cylinder 11 to rotate half a circle, thereby aligning the movable plate 12 with the sound hole 4. At this time, the block inside the lifting cylinder 2 blocks the block rod 17, and the second steering motor 20 continues to start and drive the second driving gear 21 to rotate, which can make the second steering motor 20 rotate itself and drive the motor mounting base 22 to rotate, thereby rotating the bottom column 24, and the side plate 25 rotates a certain angle to compress the second airbag 28. The gas in the second airbag 28 enters the first airbag 15, and the first airbag 15 expands and stretches to push the movable plate 12, thereby causing the ejector pin 13 to be inserted into the sound hole 4, so that the dust in the sound hole 4 can be ejected, and the device can be cleaned for easy use.

[0059] S6: The central processing unit module displays the diagnostic information on the touch panel through the display module, and at the same time uses the voice interaction module to perform voice broadcasting using the voice interaction device.
[0060] The specific process of S2 is as follows:
