[0059] A vertical driving member 6, the vertical driving member 6 comprises a second driving tube 61, a second key sleeve 62 and a vertical vibrating member, the second driving tube 61 is mounted on the supporting box 1 through a rotating seat and is concentrically arranged with the first driving tube 51, the second key sleeve 62 is mounted on the inner wall of the second driving tube 61, and the vertical vibrating member is drivingly connected to the second driving tube 61 and the vertical vibrating table 3;

[0060] A driving device 4, the driving device 4 comprising a rotating device 41, a driving shaft 42 and a positioning member 43, one end of the driving shaft 42 passes through the first driving tube 51 and the second driving tube 61 in sequence, the other end of the driving shaft 42 passes through the supporting box 1, a first key block 421 and a second key block 422 are installed on the driving shaft 42 at intervals, the first key block 421 and the second key block 422 are respectively located in the first driving tube 51 and the second driving tube 61, and the first key block 421 is located in the first key sleeve 52, and the second key block 422 is arranged adjacent to the second key sleeve 62;

[0061] The rotating device 41 is used to drive the driving shaft 42 to rotate, and the positioning member 43 is used to limit the driving shaft 42 in a horizontal direction.

[0062] When the networked terminal 20 is subjected to a vibration test, the networked terminal 20 is mounted on the vertical vibration table 3 by bolts or the like. When the networked terminal 20 is subjected to a vibration test in the horizontal direction, the rotating device 41 drives the driving shaft 42 to rotate. The driving shaft 42 drives the first driving tube 51 to rotate through the first key block 421 in cooperation with the first key sleeve 52. The first driving tube 51 drives the horizontal vibration table 2 to reciprocate through the horizontal vibration member. The horizontal vibration table 2 drives the vertical vibration table 3 to follow the horizontal vibration, thereby driving the networked terminal 20 to perform a horizontal vibration test.

[0063] When it is necessary to perform a vibration test on the network connection terminal 20 in the vertical direction, firstly, the limit of the positioning member 43 on the driving shaft 42 is unlocked, and then the tester pulls the driving shaft 42 to move toward the second driving tube 61, so that the first key block 421 moves out of the first key sleeve 52, and at this time, the second key block 422 moves into the interior of the second key sleeve 62, as shown in FIG. Fig. 9 In (a), the driving shaft 42 is again limited by the positioning member 43, and the rotating device 41 drives the driving shaft 42 to rotate again. The driving shaft 42 drives the second driving tube 61 to rotate through the second key block 422 and the second key sleeve 62, and the second driving tube 61 drives the vertical vibration table 3 to reciprocate in the vertical direction through the vertical vibration member;

[0064] By performing vibration tests in the horizontal and vertical directions, the vibration conditions to which the networked terminal 20 is subjected during use can be better simulated, so that the test equipment can be used to complete the vibration tests of the networked terminal 20 in the horizontal and vertical directions, and by adjusting the position of the drive shaft 42, a rotating device 41 can be used to complete the vibration driving of the horizontal vibration table 2 and the vertical vibration table 3, thereby simplifying the entire vibration test equipment.

[0065] Among them, during the vibration test, the networked terminal 20 is connected to the subsequent execution terminal, analysis module, etc. through the corresponding line, and whether the vibration process has any impact on the operation of the networked terminal 20, such as the vibration may cause the connection end of the line to loosen, or the internal electronic components to loosen, etc.

[0066] After the line is connected to the network terminal 20, the fixed state of the line is simulated when the network terminal 20 is installed in the vehicle body, and the line is fixed and limited to the vertical vibration table 3 to better simulate the stability of the connection between the network terminal 20 and the line connection end.

[0067] In another embodiment of the present invention, the driving device 4 includes a motor 411, an assembly frame, a main gear 412, a square shaft and two slave gears 413. The assembly frame is installed in the support box 1, the motor 411 is installed on the assembly frame, the square shaft is installed at the output end of the motor 411, the main gear 412 is sleeved on the square shaft, and a square hole adapted to the square shaft is opened in the center of the main gear 412. The two slave gears 413 are respectively installed on the first driving tube 51 and the second driving tube 61. By moving the main gear 412 to respectively mesh with the two slave gears 413, the first driving tube 51 or the second driving tube 61 is driven to rotate when the motor 411 is working;

[0068] In another embodiment of the present invention, the number of main gears 412 can also be two, and the two main gears 412 are correspondingly sleeved on the square shaft and correspondingly arranged with the two slave gears 413. According to the test requirements, one of the main gears 412 is meshed with a corresponding slave gear 413, and the other main gear 412 is separated and staggered from the other slave gear 413, so that when the motor 411 is working, the first driving tube 51 or the second driving tube 61 is driven to rotate. The two main gears 412 can also be meshed with the two slave gears 413 accordingly, so that when the motor 411 is working, the first driving tube 51 and the second driving tube 61 are driven to rotate at the same time, so that horizontal vibration testing and vertical vibration testing can be carried out at the same time.

[0069] Please refer again Figure 4 As a preferred embodiment of the present invention, multiple groups of the first key sleeves 52 and the second key sleeves 62 are provided, and the multiple groups of the first key sleeves 52 and the multiple groups of the second key sleeves 62 are respectively and correspondingly installed in the first driving tube 51 and the second driving tube 61. The number of each group of the first key sleeves 52 and the number of each group of the second key sleeves 62 are two, and they are arranged in the same straight line, wherein the two first key sleeves 52 in each group are arranged at intervals, and the spacing value is greater than the length value of the first key block 421, and the two second key sleeves 62 in each group are arranged adjacent to each other.

[0070] When conducting horizontal vibration tests, such as Figure 4, the first key block 421 is assembled with the first key cover 52, and the second key block 422 is separated from the second key cover 62. When a vertical vibration test is performed, as shown in FIG. Fig. 9 (a) the first key block 421 is separated from the first key cover 52 and is located between the two first key covers 52; the second key block 422 is assembled with the second key cover 62. When the horizontal vibration test and the vertical vibration test need to be performed simultaneously, as shown in FIG.

The simultaneous horizontal and vertical vibration tests can better simulate the vibration that the networked terminal 20 may be subjected to during the driving of the vehicle, and at the same time enable the vibration test equipment to have more test functions.

[0071] That is, by adjusting the position of the driving shaft 42, the driving device 4 cooperates with the horizontal vibrating member and the vertical vibrating member to drive the horizontal vibrating table 2 to work, or drive the vertical vibrating table 3 to work, or drive the horizontal vibrating table 2 and the vertical vibrating table 3 to work simultaneously.

[0072] In this embodiment, the number of groups of the first key cover 52 and the second key cover 62 is the same, and is not less than two groups; the number of the first key blocks 421 and the second key blocks 422 is the same as the number of the first key cover 52 and the second key cover 62;

[0073] By providing a plurality of first key blocks 421 and second key blocks 422 and assembling them correspondingly with the first key sleeve 52 and the second key sleeve 62 , the driving shaft 42 can more stably drive the first driving tube 51 and the second driving tube 61 to rotate.

[0074] See also Figure 2In this embodiment, the horizontal vibration table 2 includes a vibration plate 21, four first springs 22 and four transverse guide columns 23.

[0075] The first spring 22 is provided to buffer the vibration plate 21 when it vibrates horizontally, thereby improving the stability of the vibration plate 21 when it vibrates.

[0076] See also Figure 2 In this embodiment, the vertical vibration table 3 includes a bearing plate 31, four second springs 32 and four vertical guide columns 33. The four vertical guide columns 33 are respectively installed on the four corners of the top of the vibration plate 21.

Each second spring 32 is correspondingly sleeved on each vertical guide column 33 and is located between the bearing plate 31 and the vibration plate 21.

[0077] The second spring 32 buffers the vertical vibration of the bearing plate 31 , thereby improving the stability of the bearing plate 31 during vibration.

[0078] Among them, a plurality of threaded assembly holes are opened on the supporting plate 31, and mounting frames are arranged on both sides of the networked terminal 20. The mounting frames are correspondingly opened with mounting holes, and the networked terminal 20 is installed by bolts passing through the mounting holes and threadedly connected with the corresponding threaded assembly holes.

[0079] Please refer to Figure 4 and Figure 6 In this embodiment, the horizontal vibration member includes a rotating block 53, a convex shaft 54 ​​and a driving frame 55. The rotating block 53 is installed on the first driving tube 51. The top of the driving frame 55 passes through the opening 11 and is connected to the horizontal vibration table 2. One end of the convex shaft 54 ​​is connected to the rotating block 53, and the other end passes through the driving frame 55.

[0080] In this example, an opening 11 is formed on the top of the support box 1 , and the top end of the driving frame 55 passes through the opening 11 and is connected to the vibration plate 21 .

[0081] Please refer to Figure 8 (a) and Figure 8In (b), when the first driving tube 51 rotates, the rotating block 53 is driven to rotate accordingly, and the rotating block 53 drives the convex shaft 54 ​​to rotate. During the rotation of the convex shaft 54, while sliding along the driving frame 55, the driving frame 55 is pushed to vibrate horizontally. The driving frame 55 drives the vibration plate 21 to vibrate reciprocatingly. The vibration plate 21 drives the network terminal 20 to perform a horizontal vibration test through the vertical vibration table 3, so that when the first driving tube 51 rotates, the horizontal vibration table 2 is driven to vibrate horizontally through the vertical vibration member.

[0082] Among them, the driving frame 55 is slidably connected to the mounting partition in the support box 1, thereby improving the stability of the driving frame 55 during reciprocating movement; a sliding rod is installed on the mounting partition through a connecting ear, and the bottom end of the driving frame 55 is sleeved on the sliding rod to form a sliding assembly.

[0083] In other embodiments, the horizontal vibration member includes a rotating block 53, a convex shaft 54, a first driving rod and a second driving rod. The rotating block 53 is installed on the first driving tube 51, the convex shaft 54 ​​is installed on the rotating block 53, one end of the first driving rod is sleeved on the convex shaft 54, and the other end is rotatably connected to one end of the second driving rod, and the other end of the second driving rod is rotatably connected to the vibration plate 21.

[0084] Please refer to Figure 4 and Figure 6 In this embodiment, the vertical vibrating member includes a cam 63, an elliptical sleeve 64 and a driving arm 65. The cam 63 is installed on the second driving tube 61, and the elliptical sleeve 64 is sleeved on the second driving tube 61. The cam 63 abuts against the inner wall of the elliptical sleeve 64. One end of the driving arm 65 is connected to the elliptical sleeve 64, and the other end of the driving arm 65 passes through the horizontal vibration table 2 through the sliding hole 211 and is slidably connected to the vertical vibration table 3.

[0085] In this embodiment, the other end of the driving arm 65 is slidably connected to the carrying plate 31 through the opening 11 and the sliding hole 211 in sequence.

[0086] Please refer to Figure 8 (c) and Figure 8 In (d), when the second driving tube 61 rotates, the cam 63 is driven to rotate. The cam 63 acts on the inner wall of the elliptical sleeve 64 to push the elliptical sleeve 64 to move up and down. The elliptical sleeve 64 drives the supporting plate 31 to vibrate up and down through the driving arm 65. The supporting plate 31 drives the network terminal 20 to perform a vertical vibration test, thereby realizing that the second driving tube 61 drives the supporting plate 31 to perform a vertical vibration test through the vertical vibrating member.

[0087] Among them, by slidingly connecting the driving arm 65 with the supporting plate 31, when the network terminal 20 performs horizontal and vertical vibration tests at the same time, when the supporting plate 31 follows the horizontal vibration table 2 to perform horizontal vibration, the driving arm 65 slides relative to the supporting plate 31, which does not affect the driving arm 65 driving the supporting plate 31 to perform vertical vibration test.

[0088] A sliding arm is installed at the bottom of the carrying plate 31 through a connecting ear, and the top end of the driving arm 65 is sleeved on the sliding arm to form a sliding connection.

[0089] Among them, a roller is provided at one end of the cam 63 that acts on the inner wall of the elliptical sleeve 64, so as to reduce the friction when the cam 63 acts on the inner wall of the elliptical sleeve 64 and extend the service life of the component.

[0090] In other embodiments, the vertical vibrating member includes a cam 63 and a driving arm 65, the bottom of the driving arm 65 is set as an arc surface, the cam 63 is mounted on the second driving tube 61, and the top of the driving arm 65 is similarly slidably mounted on the bearing plate 31, and the cam 63 abuts against the bottom end of the second driving tube 61. By setting the bottom end of the driving arm 65 as an arc surface, when the cam 63 rotates and acts on the bottom end of the driving arm 65, it acts on the arc surface at the bottom end of the driving arm 65, making it easier to push up the driving arm 65 and drive the bearing plate 31 to move upward. When the cam 63 is subsequently separated from the driving arm 65, the bearing plate 31 drops by gravity, thereby achieving up and down reciprocating vibration.

[0091] See also Figure 2 and Figure 3 In this embodiment, the rotating device 41 includes a motor 411, a main gear 412 and a slave gear 413.

The rotating tube 4131 is connected to the driving shaft 42 by a sliding key 4132, and the slave gear 413 is meshed with the main gear 412.

[0097] When the positions of the first key block 421 and the second key block 422 need to be adjusted, firstly turn the driving pin 432 so that the driving pin 432 drives the positioning block 433 to move upward, so that the positioning block 433 moves out of the annular positioning groove 424. When the positions of the first key block 421 and the second key block 422 are adjusted accordingly, the positioning block 433 is aligned with another annular positioning groove 424. Then, turn the driving pin 432 again to rotate, and the driving pin 432 pushes the positioning block 433 to be inserted into the corresponding annular positioning groove 424 to achieve limiting.

[0098] The annular positioning groove 424 cooperates with the positioning block 433 to limit the driving shaft 42 in the horizontal direction without affecting the axial rotation of the driving shaft 42 .

[0099] Preferably, rolling elements are provided on both sides of the positioning block 433. In this embodiment, the rolling elements are balls, which are embedded in the positioning block 433.

The bracket 91 is arranged adjacent to the supporting box 1, and the interference source 92 is installed on the top of the bracket 91.

[0103] By setting the interference device 9, when the networked terminal 20 is working, the interference signal is released through the interference source 92, and the communication anti-interference ability of the networked terminal 20 can be detected;

[0104] The interference source 92 includes a noise generator and an electromagnetic interference generator. The noise generator can generate Gaussian white noise, pulse noise, etc. These noises can simulate the interference generated by electrical equipment and other vehicles in the tunnel, as well as the thermal noise that the signal is subjected to during transmission. By adjusting the power spectrum density, intensity and other parameters of the noise, the communication performance of the networked terminal 20 under noise interference, such as bit error rate, signal distortion, etc., is observed;

[0106] The noise generator and the electromagnetic interference generator can be installed on the bracket 91 in sequence to perform the corresponding interference test. The vibration test and the interference test can be combined for testing, that is, the corresponding interference test can be performed while the vibration is performed.

[0107] During the test, according to the test requirements, the bracket 91 is placed at a preset distance from the support box 1 (ie, the network terminal 20), preferably 1-3 meters, and can also be set to other distances according to the test environment.

[0108] The bracket 91 includes a base plate, a support and a mounting plate, wherein the support connects the base plate and the mounting plate, and the interference source 92 is mounted on the mounting plate, wherein the support is formed by a plurality of short columns threadedly spliced ​​together, so that the height of the interference source 92 can be adjusted as required.

When there are four interference sources 92, they are evenly arranged on the four sides of the support box 1. By evenly arranging the interference sources 92 around the network terminal 20, a uniform interference environment can be created to ensure that each part of the object under test is subjected to relatively balanced interference.

[0110] See also Figure 2 As an optional method of this embodiment, the terminal testing device of the intelligent connected vehicle also includes a belt winding device 7, which includes a rotating shaft 71, a winding wheel 72, a connecting belt 73 and a rotating device 74. The rotating shaft 71 is rotatably installed inside the supporting box 1, and the winding wheel 72 is installed on the rotating shaft 71. One end of the connecting belt 73 is connected to the winding wheel 72, and the other end of the connecting belt 73 passes through the supporting box 1 through a through hole 12 and is connected to the connecting plate 911 of the bracket 91. The rotating device 74 is used to drive the rotating shaft 71 to rotate, and a scale value is set on the connecting belt 73.

[0111] By setting the connecting belt 73, when the bracket 91 is moved, the connecting belt 73 is driven to move along, and the connecting belt 73 drives the winding wheel 72 to rotate, and the connecting belt 73 is roped. According to the scale value on the connecting belt 73, it is convenient to determine the distance between the bracket 91 and the support box 1, that is, the distance between the interference source 92 and the network terminal 20, and the connecting belt 73 is kept perpendicular to the side of the support box 1, so that the orientation of the interference source 92 can be easily determined.

[0112] See also Figure 2 The bottom of the support box 1 is provided with a base 10, the base 10 is provided with an assembly plate 101, the top of the assembly plate 101 is provided with a guide frame, the connecting belt 73 passes through the guide frame, the guide frame can limit the connecting belt 73, and when the connecting belt 73 is straightened, it passes through the guide frame without contacting the guide frame, and at this time, the connecting belt 73 is perpendicular to the corresponding side of the support box 1;

[0113] The bottom of the bracket 91 is provided with rollers to facilitate the movement of the bracket 91 .

[0114] A positioning shaft 102 is installed on the assembly plate 101, and a positioning hole 912 is opened on the corresponding connecting plate 911. When no test is performed, the rotating device 74 drives the rotating shaft 71 to rotate, thereby driving the winding wheel 72 to rotate, and winding and storing the connecting belt 73. The connecting belt 73 can drive the bracket 91 to move toward the support box 1, and finally the positioning hole 912 on the connecting plate 911 is correspondingly sleeved on the positioning shaft 102, limiting the bracket 91, so that the bracket 91 is retracted to be adjacent to the support box 1, thereby reducing space occupancy.

[0115] The rotating shaft 71 may be provided with a plurality of winding wheels 72 as required, each winding wheel 72 may be connected to two symmetrically arranged connecting belts 73 , and each connecting belt 73 corresponds to an interference device 9 .

[0116] Please refer to the figure Figure 2 and Figure 4 As an optional manner of this embodiment, the rotating device 74 is a slave bevel gear, and the terminal testing device of the intelligent connected vehicle further includes a rotating driving member 8, which includes a third driving tube 81, a third key sleeve 82 and a main bevel gear 83. The third driving tube 81 is rotatably installed in the supporting box 1 through a rotating seat, and the third driving tube 81 is located between the first driving tube 51 and the second driving tube 61. The third driving tube 81, the first driving tube 51 and the second driving tube 61 are concentrically arranged, the third key sleeve 82 is installed on the inner wall of the third driving tube 81, and the main bevel gear 83 is sleeved and installed on the third driving tube 81. The main bevel gear 83 is meshed with the rotating device 74, and a third key block 423 is installed on the driving shaft 42 and located inside the third driving tube 81; when the third key block 423 is assembled with the third key sleeve 82, the first key block 421 is separated from the first key sleeve 52, and the second key block 422 is separated from the second key sleeve 62.

[0117] Please refer to Fig. 9 (c) to Fig. 9 In (d), Fig. 9 In the state (c), the driving shaft 42 is continuously pulled in the direction of the rotating device 41, so that the first key block 421 is separated from the two first key sleeves 52 of each group, and the second key block 422 is separated from the two second key sleeves 62 of each group. The third key block 423 is assembled with the corresponding third key sleeve 82 at this time. At this time, when the rotating device 41 drives the driving shaft 42 to rotate, the third key block 423 can cooperate with the third key sleeve 82 to drive the third driving tube 81 to rotate. The third driving tube 81 drives the rotating device 74 (slave bevel gear) to rotate through the main bevel gear 83, thereby driving the rotating shaft 71 to rotate. The rotating shaft 71 drives the winding wheel 72 to rotate, so as to realize the storage of the connecting belt 73. Therefore, the driving belt winding device 7 can be driven to work by utilizing the rotating device 41, and no additional driving equipment is required.

[0118] Preferably, the rotating device 74 is a unidirectional slave bevel gear, which is installed on the rotating shaft 71 through a unidirectional bearing. The main bevel gear 83 can drive the rotating shaft 71 to rotate through the rotating device 74, and the connecting belt 73 is wound and stored through the winding wheel 72. When the movable bracket 91 pulls the connecting belt 73 out of the support box 1 and drives the rotating shaft 71 to rotate, the rotating device 74 cannot drive the third driving tube 81 to rotate through the main bevel gear 83, so that the third key sleeve 82 can remain aligned with the third key block 423.

[0119] Each time the rotating device 41 drives the driving shaft 42 to rotate until it stops, it is an integer number of circles, so that each key block and the corresponding key sleeve can be kept aligned.

[0120] As another optional mode of this embodiment, the rotating device 74 includes a fixing frame and a rotating motor. The rotating motor is installed inside the supporting box 1 through the fixing frame. The output shaft of the rotating motor is connected to the rotating shaft 71 to drive the rotating shaft 71 to rotate.

[0121] Among them, the rotating seat used to install the first driving tube 51, the second driving tube 61 and the third driving tube 81 can be a bearing seat, which is correspondingly mounted on the first driving tube 51, the second driving tube 61 and the third driving tube 81 and installed correspondingly with the support box 1.

[0122] Among them, the rotating device 41 corresponds to the states of driving horizontal vibration test, driving vertical vibration test, driving horizontal vibration test and vertical vibration test at the same time, and the working state of driving the winding device 7, and four annular positioning grooves 424 are correspondingly arranged on the driving shaft 42; corresponding to different states, the positioning piece 43 cooperates with each annular positioning groove 424 to limit the driving shaft 42 in the horizontal direction.

[0123] The working principle of the terminal testing device for intelligent connected vehicles provided by the present invention is as follows:

[0124] When the networked terminal 20 is subjected to a vibration test, the networked terminal 20 is mounted on the vertical vibration table 3 by bolts or the like. When the networked terminal 20 is subjected to a vibration test in the horizontal direction, the rotating device 41 drives the driving shaft 42 to rotate. The driving shaft 42 drives the first driving tube 51 to rotate through the first key block 421 in cooperation with the first key sleeve 52. The first driving tube 51 drives the horizontal vibration table 2 to reciprocate through the horizontal vibration member. The horizontal vibration table 2 drives the vertical vibration table 3 to follow the horizontal vibration, thereby driving the networked terminal 20 to perform a horizontal vibration test.

[0125] When it is necessary to perform a vibration test on the network connection terminal 20 in the vertical direction, firstly, the limit of the positioning member 43 on the driving shaft 42 is unlocked, and then the driving shaft 42 is pulled toward the second driving tube 61, so that the first key block 421 moves out of the first key sleeve 52 and is located between the two first key sleeves 52. At this time, the second key block 422 moves into the interior of the second key sleeve 62, as shown in FIG. Fig. 9 (a); then the driving shaft 42 is limited again by the positioning member 43, the rotating device 41 drives the driving shaft 42 to rotate again, the driving shaft 42 drives the second driving tube 61 to rotate through the second key block 422 and the second key sleeve 62, and the second driving tube 61 drives the vertical vibration table 3 to reciprocate in the vertical direction through the vertical vibration member;

[0126] When horizontal vibration test and vertical vibration test need to be carried out at the same time, such as Fig. 9 In (b), the drive shaft 42 continues to be pulled toward the second driving tube 61, so that the first key block 421 is assembled with another first key sleeve 52 in the same group, and the second key block 422 is assembled with another second key sleeve 62 in the same group, so that the rotating device 41 drives the drive shaft 42 to rotate, and the drive shaft 42 drives the first driving tube 51 and the second driving tube 61 to rotate respectively through the first key block 421 and the second key block 422 correspondingly cooperate with the first key sleeve 52 and the second key sleeve 62, so as to drive the horizontal vibration table 2 to work through the horizontal vibration member, and the horizontal vibration table 2 drives the vertical vibration table 3 to follow the horizontal vibration, and at the same time the vertical vibration member drives the vertical vibration table 3 to work, so as to realize the simultaneous driving of the networked terminal 20 to perform vibration tests in the horizontal and vertical directions. The simultaneous horizontal and vertical vibration tests can better simulate the vibration that the networked terminal 20 may be subjected to during the driving of the vehicle, and at the same time enable the vibration test equipment to have more test functions.

[0127] That is, by adjusting the position of the driving shaft 42, the driving device 4 cooperates with the horizontal vibrating member and the vertical vibrating member to drive the horizontal vibrating table 2 to work, or drive the vertical vibrating table 3 to work, or drive the horizontal vibrating table 2 and the vertical vibrating table 3 to work simultaneously.

[0128] The present invention also provides a terminal testing system for an intelligent network-connected vehicle;

[0129] See also Fig.11 The terminal testing system of the intelligent connected vehicle includes: a signal generator, an execution terminal, an analysis module and the terminal testing device of the intelligent connected vehicle.

[0131] The output end of the network connection terminal 20 is correspondingly connected to the execution terminal and the analysis module signal;

[0132] The execution terminal includes a display screen and various applications for smart connected cars;

[0133] During vibration testing and interference testing, the functions of the application are tested to see whether they are implemented normally, whether the response time meets the requirements, etc. The application includes some test programs, such as programs for testing network speed, which can detect the real-time network speed under signal interference.

[0134] The analysis module includes spectrum analyzer, oscilloscope, etc.:

[0135] The spectrum analyzer can analyze the spectrum of vehicle communication signals, monitor the signal's frequency range, bandwidth, power distribution and other parameters to ensure that the signal complies with relevant standards and protocol requirements. It is also used to detect electromagnetic interference, etc.

[0136] The oscilloscope is used to detect various electrical signal waveforms input and output by the networked terminal 20, such as the high and low level changes of digital signals, the amplitude and period changes of analog signals, etc. The staff can analyze whether the signal transmission of the networked terminal 20 is normal by observing the waveform, and whether there are problems such as signal distortion and jitter.
