[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0021] See Figure 1The present invention provides an automatic testing system 100 for testing a multimedia device 101 to be tested, comprising a first testing device 102, a testing mobile phone 103, and a mobile carrying device 104. The multimedia device 101 to be tested can be a car audio system, a car DVD / CD player, a car Bluetooth connection system, a car touch screen display, a car USB interface system, a car wireless network connection system, a car mobile phone projection system, a car mobile phone projection system, a car camera system, or a car GPS navigation system. Through the automatic testing system 100, the Bluetooth distance test of the multimedia device 101 to be tested can be automatically performed without the need for the tester to move around or participate too much. In addition, the overall test has a foolproof function, is fast and efficient, and can also improve the test quality, thus effectively solving the shortcomings of the background technology.

[0022] In the automatic testing system 100, the first testing device 102 is used to connect to the multimedia device under test 101; the testing mobile phone 103 is connected to the first testing device 102 via a Bluetooth mode, and the testing mobile phone 103 transmits a test audio to the multimedia device under test 101 via the Bluetooth mode and controls the multimedia device under test 101 to play the test audio.

[0023] The mobile carrier 104 is used to move the test mobile phone 103. The following description assumes that the mobile carrier is a magnetic levitation power device: After the test mobile phone 103 is moved to a position a standard distance away from the multimedia device 101 to be tested by the magnetic levitation power device 104, the first test device 102 obtains the audio output value of the multimedia device 101 to be tested after playing the test audio, and determines whether the audio output value is within the standard numerical range. When the audio output value is within the standard numerical range, the test result of the multimedia device 101 to be tested is passed. When the audio output value is not within the standard numerical range, the test result of the multimedia device 101 to be tested is failed. Secondly, in order to meet the requirements of the Bluetooth distance test, the standard distance is 10 meters.

[0024] Furthermore, the audio output value is a voltage output value, a frequency output value, or a phase difference output value. If the audio output value is a voltage output value, that is, the first test device obtains the voltage output value of the multimedia device 101 under test after playing the test audio, assuming that the standard value range after playing the test audio is 2.0V-2.8V, if the voltage output value at this time is between 2.0V-2.8V, it means that the function of the multimedia device 101 under test is normal at this time, and the test result is passed. The first test device outputs a test normal message. If the voltage output value at this time is not between 2.0V-2.8V, it means that the function of the multimedia device 101 under test is abnormal at this time, and the test result is failed. The first test device outputs a test abnormal message. Similarly, when the audio output value is a frequency output value or a phase difference output value, the test principle is the same as when the audio output value is a voltage value, and will not be repeated here.

[0025] As a preferred embodiment, the magnetic levitation power unit 104 utilizes electromagnetic force to suspend the test phone 103 in a magnetic field. By controlling the magnitude and direction of the electromagnetic force, the test phone 103 achieves stable levitation and motion control. The magnetic levitation power unit 104 comprises a magnetic levitation track, sensors, a controller, and a power supply. The sensors detect the position, speed, and posture of the object and transmit this information to the controller. Based on the sensor feedback, the controller adjusts the magnitude and direction of the electromagnetic force to control the levitation state and motion trajectory of the test phone 103 within the magnetic levitation track. The power supply provides the required electrical energy. This method enables the movement of the test phone 103 to be controlled.

[0026] As another preferred embodiment, the first test device 102 is further configured to upload the test results to a cloud server. By uploading the test results to the cloud server, users and other terminals can conveniently and quickly obtain the test results by connecting to the cloud server.

[0027] As another preferred embodiment, the automatic testing system 100 further includes a second testing device, which is configured to control the test phone 103 to turn on the Bluetooth mode and to control the test phone 103 to transmit the test audio to the multimedia device 101 under test via the Bluetooth mode. The second testing device controls the test phone 103 to control the multimedia device 101 under test to play the test audio via the Bluetooth mode. The second testing device can be an industrial computer or other terminal device with control functions.

[0028] Next, see Figure 2The present invention also provides an automatic testing method for testing a multimedia device 101 to be tested. The multimedia device 101 to be tested can be a car audio system, a car DVD / CD player, a car Bluetooth connection system, a car touch screen display, a car USB interface system, a car wireless network connection system, a car mobile phone projection system, a car mobile phone projection system, a car camera system, or a car GPS navigation system. Through this automatic testing method, the Bluetooth distance test of the multimedia device 101 to be tested can be automatically performed without the need for the tester to walk back and forth or excessive participation. In addition, the overall test also has a fool-proof function, is fast and efficient, and can improve the test quality, thus effectively solving the shortcomings of the background technology. The steps of this automatic testing method are described below.

[0029] Step 101: Connect the multimedia device 101 to be tested to the first test equipment 102 and turn on the power. First, connect the multimedia device 101 to the first test equipment 102, either by wired or wireless connection, and turn on the power of the multimedia device 101. The first test equipment can be an industrial computer or other terminal device with control functions.

[0030] Step 102. The first test device 102 controls the multimedia device to be tested 101 to turn on the Bluetooth mode so that the multimedia device to be tested 101 can communicate with a test mobile phone through the Bluetooth mode. In detail, the test mobile phone turns on the Bluetooth mode under the control of a second test device, the second test device controls the test mobile phone to transmit the test audio to the multimedia device to be tested through the Bluetooth mode, and the second test device controls the test mobile phone to control the multimedia device to be tested to play the test audio through the Bluetooth mode. The function of the second test device is to control the test mobile phone to turn on the Bluetooth mode, and to control the test mobile phone to transmit the test audio to the multimedia device to be tested through the Bluetooth mode. In addition, the second test device is also used to control the test mobile phone to control the multimedia device to be tested to play the test audio through the Bluetooth mode. Among them, the second test device can be an industrial computer or other terminal device with control function.

[0031] Step 103. The test phone 103 transmits the test audio to the multimedia device 101 under test via Bluetooth and controls the multimedia device 101 to play the test audio. The operating system of the test phone 103 can be Android or iOS and must have Bluetooth functionality. Its function is to connect to the multimedia device 101 under test via Bluetooth and send the test audio to the multimedia device 101 under test. The test audio is a complete audio segment. During the test, when the test phone 103 is away from the multimedia device 101 under test, the collected audio is collected to determine whether it corresponds to the original audio, thereby determining whether the multimedia device 101 under test passes the Bluetooth distance test.

[0032] Step 104: Use a mobile carrier to move the test phone to a position a standard distance from the multimedia device under test. This mobile carrier can be a magnetic levitation power unit 104, which uses electromagnetic force to suspend the test phone 103 in a magnetic field. By controlling the magnitude and direction of the electromagnetic force, the test phone 103 maintains stable suspension and motion control. The magnetic levitation power unit 104 comprises a magnetic levitation track, sensors, a controller, and a power supply. The sensors detect the position, speed, and posture of the object and transmit this information to the controller. Based on the sensor feedback, the controller adjusts the magnitude and direction of the electromagnetic force to control the suspension state and motion trajectory of the test phone 103 within the magnetic levitation track. The power supply provides the required electrical energy. This method allows for movement control of the test phone 103.

[0033] Step 105. When the multimedia device under test plays the test audio, the first test device obtains an audio output value of the multimedia device under test and determines whether the audio output value is within a standard numerical range. After the test mobile phone is moved to a standard distance from the multimedia device under test via the mobile carrier, the first test device obtains an audio output value of the multimedia device under test when playing the test audio and determines whether the audio output value is within the standard numerical range. The audio output value refers to the numerical value, such as voltage, frequency, or current, generated by the multimedia device under test when playing the test audio. The first test device primarily collects the audio output value of the audio component and determines whether the audio output value is within the standard numerical range. If the audio output value is within the standard numerical range, the process proceeds to step 106; if the audio output value is not within the standard numerical range, the process proceeds to step 107. Secondly, to meet the requirements of Bluetooth distance testing, the standard distance is 10 meters.

[0034] Step 106: When the audio output value is within the standard value range, the first test device outputs a test normal message. In other words, if the collected audio output value is within the standard value range, it means that the wireless transmission function of the multimedia device under test has passed the Bluetooth distance test.

[0035] Step 107: If the audio output value is not within the standard value range, the first test device outputs a test abnormality message. In other words, if the collected audio output value is not within the standard value range, it means that the wireless transmission function of the multimedia device under test fails the Bluetooth distance test.

[0036] It should be noted that the audio output value is a voltage output value or a frequency output value or a phase difference output value. Furthermore, the audio output value is a voltage output value or a frequency output value or a phase difference output value. If the audio output value is a voltage output value, that is to say, the first test device obtains the voltage output value after the multimedia device 101 to be tested plays the test audio. Assuming that the standard numerical value range after playing the test audio at this time is 2.0V-2.8V, if the voltage output value at this time is between 2.0V-2.8V, it means that the function of the multimedia device 101 to be tested is normal at this time, and the test result is passed. Similarly, when the audio output value is a frequency output value or a phase difference output value, the principle of the test is the same as that when the audio output value is a voltage numerical value, and will not be repeated here.

[0037] Step 108: The first test device uploads the test results to a cloud server. By uploading the test results to the cloud server, users and other terminals can easily and quickly obtain the test results by connecting to the cloud server.
