[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0041] like Figure 1 As shown, a certain type of flight equipment communication performance rapid testing equipment is mainly composed of a communication headset 1, a switching cable 2, a power adapter 3, a charging cable 4, a protective foam 5, a detector 6, a trace foam 7, and a three-proof protective box 8.

[0042] Specifically, the trace foam 7 is fixedly installed at the bottom of the three-proof protection box 8. The trace foam 7 is made of hard EVA foam and is customized according to the shape of the internal components. It is used to store and protect the internal components. The communication headset 1, the adapter cable 2, the power adapter 3, the charging cable 4 and the detector 6 are placed on the trace foam 7 accordingly. The protective foam 5 is made of soft corrugated foam and is fixedly installed on the top of the three-proof protection box 8 to protect the internal components.

[0043] Furthermore, if Figure 2 and Figure 3As shown, the detector 6 is mainly composed of a power switch 9, a housing 10, an integrated circuit board 11, a liquid crystal screen 12, a lithium battery 13, an aviation plug protective cap 14, an aviation plug 15, a function button 16, a charging interface 17, and a charging interface protective cap 18.

[0044] The power switch 9 , LCD screen 12 , aviation plug protective cap 14 , aviation plug 15 , function button 16 , charging interface 17 and charging interface protective cap 18 are arranged on the outside of the housing 10 ; the integrated circuit board 11 and the lithium battery 13 are arranged on the inside of the housing 10 .

[0045] Specifically, the integrated circuit board 11 includes a battery management module 19, a microprocessor 20, a power supply processing module 21, an audio signal processing module 22, and a signal amplification module 23. The battery management module 19 is connected to the lithium battery 13, the microprocessor 20 and the power supply processing module 21 are connected to the battery management module 19, the microprocessor 20 and the power supply processing module 21 are connected to the LCD screen 12, the audio signal processing module 22 is connected to the microprocessor 20 and the power supply processing module 21, and the signal amplification module 23 is connected to the audio signal processing module 22.

[0046] The working principle of the integrated circuit board 11 is as follows: the detection audio signal data is transmitted to the audio signal processing module 22 through the I2S bus, and after being decoded and amplified into an analog signal, it is transmitted to the earphone speaker (test object) for playing, so as to detect whether the earphone speaker function is intact; at the same time, the sound signal of the microphone (test object) on the mask can be detected in real time, the sound signal is amplified by the signal amplification module 23, converted into a digital signal by the audio signal processing module 22, and then transmitted to the microprocessor 20 through the I2S bus, and the microprocessor 20 performs Fourier transformation on the signal, and displays the visual spectrum of the sound on the LCD screen 12, so as to detect whether the microphone function on the mask is intact. The battery management module 19 is used to detect the power information and charging status of the lithium battery 13 in real time, and transmit the information to the microprocessor 20 for management.

[0047] like Figure 4As shown, the LCD screen 12 adopts an economical design, a circular display window, an interface with black as the background color, emerald green as the main display color, and is distinguished by color according to different display contents. The display content includes a model indication 24, an audio waveform 25, a power indication 26, an audio playback prompt 27, a charging prompt 28, and a charging end prompt 29. Among them, the model indication 24 is mainly used to indicate the model of the flight equipment currently adapted for testing. The audio waveform 25 is used to indicate the strength of the collected audio signal in the form of a change in waveform amplitude. The power indication 26 is used to indicate the remaining power of the current internal lithium battery 13. The audio playback prompt 27 is used to indicate that the detector 6 is currently in an audio playback state. The charging prompt 28 is used to indicate that the detector 6 is currently in a charging state. The charging end prompt 29 is used to indicate that the detector 6 is currently in a charging complete state.

[0048] Users can judge the model of the flight equipment being tested, the current power of the tester, the real-time waveform of the audio input, and the current status of the tester based on the interface content.

[0049] like Figure 5 As shown, it is a software flow chart on the detector 6. The corresponding software modules are set in the microprocessor 20, specifically including a battery status real-time detection function module, an external sound signal real-time playback function module, an external sound signal visual display function module, a playback system built-in audio function module, and a flight equipment model switching detection function module. The specific introduction is as follows:

[0050] The battery status real-time detection function module: after the system is powered on, the hardware is initialized, and the software background performs real-time battery status detection, reads the charging status and power information of the lithium battery 13, and processes the status information through the LCD screen display task, and displays it in the corresponding position of the LCD screen 12 in the form of a charging prompt 28.

[0051] The external sound signal real-time playback function module: after the hardware is initialized, when the charging detection is in a non-charging state, the system background collects the external sound signal in real time and changes it into an external audio stream, which is encoded by the external audio and played in real time through the audio amplification output.

[0052] The external sound signal visualization display function module: After the external sound signal real-time playback function module encodes the external audio, the data is processed by the visualization waveform task and displayed in the corresponding position on the LCD screen 12 in the form of an audio waveform 25 through the LCD screen display task.

[0053] The playback system has its own audio function module: when the charging detection is in a non-charging state, when the background key detects that the function button 16 is short pressed, the system calls the built-in audio file, decodes the built-in audio data, and plays it through audio amplification output.

[0054] The switching detection flight equipment model function module: when the charging detection is in a non-charging state, when the background key detects that the function button 16 is long pressed, the flight equipment model can be switched, and the system sets the audio decoder parameters of the corresponding model to facilitate calling when the audio is amplified and output.

[0055] The lithium battery 13 is used to provide power to the system. The aviation plug protective cap 14 is used to provide protection for the aviation plug 15. The aviation plug 15 can be connected to the communication headset 1 or the adapter cable 2, and connected to the flight equipment under test for signal acquisition interaction. The function button 16 has two functions: first, it is used to switch the model of the flight equipment under test; second, it is used to play test audio. The charging interface 17 is connected to the power adapter 3 through the charging cable 4, and is used to charge the lithium battery 13. The charging interface protective cap 18 is used to provide protection for the charging interface 17.

[0056] Furthermore, a method for quickly testing the communication performance of a certain type of flight equipment is provided, which uses the above-mentioned equipment for quickly testing the communication performance of a certain type of flight equipment, including three application scenarios: overall testing of the communication equipment, testing of the receiver alone, and testing of the transmitter alone.

[0059] Step b), long press the function button 16, observe the model indication 24 to switch the test product model, after confirming that it is correct, correctly wear the flight equipment to be tested.

[0060] Step c) judging the performance of the product under test by speaking and listening to oneself. If the user can clearly hear what he / she is saying, the product under test is qualified.

[0061] Step d), if normal speech cannot be heard and the audio waveform 25 shows normal, the microphone is damaged.

[0062] Step e), if normal speaking sound cannot be heard and the audio waveform 25 has no waveform display, click the function button 16 to play the test audio, and the user interface displays an audio play prompt 27. If the audio can be heard normally, the receiver is damaged.

[0063] Step f), if both step d and step e are abnormal, then both the transmitter and the receiver are faulty.

[0064] Testing the receiver alone includes the following steps:

[0065] Step A), confirm the model of the receiver to be tested, and after confirming the model, connect the corresponding plugs of the communication headset 1 to the receiver to be tested and the tester 6 respectively.

[0066] Step B), long press the function button 16, observe the model indication 24 to switch the test product model, and after confirming that it is correct, wear the communication headset 1 correctly.

[0067] Step C) judging the performance of the receiver under test by speaking and listening to oneself. If the user can clearly hear the content of his / her speech and the audio waveform 25 is normal, the receiver under test is qualified, otherwise it is faulty.

[0068] The microphone stand-alone test includes the following steps:

[0069] Step I): confirm the model of the flight equipment to be tested. After confirming the model, connect the two ends of the adapter cable 2 to the product to be tested and the detector 6 respectively.

[0070] Step II), long press the function button 16, observe the model indication 24 to switch the test product model, after confirming that it is correct, correctly wear the flight equipment to be tested.
