Description

Technical Field

[0001] This application relates to the field of air respirator testing equipment, and more particularly to a communication device testing system for an air respirator testing instrument. Background Technology

[0002] Currently, personal protective equipment (PPE) in modern firefighting is constantly being upgraded. To enable smoother communication between attack personnel and command personnel outside the site, protective masks, in addition to meeting basic protection requirements, also need to be equipped with communication devices to meet communication needs. The ability to promptly transmit the situation on-site to the outside and transmit command information from the outside to the site plays a crucial role in the personal safety of both attack personnel and trapped personnel.

[0003] Currently, there are numerous brands of air respirator testing equipment on the market, but their testing functions are mostly focused on testing pressure data related to the air respirator, such as: high pressure, medium pressure, mask pressure, breathing resistance, air supply pressure, valve opening force, alarm whistle opening pressure, pressure gauge accuracy, and pressure leakage performance testing. However, there is no specialized equipment to test the performance of the communication device. The following steps are used to perform a general check of the communication device: First, the function of the communication device is tested separately: after the communication device is assembled and manufactured, a voice communication test is performed to verify whether the communication device itself is malfunctioning. Then, the communication device is assembled with the mask and its performance is tested. After the communication device and mask are assembled, quality inspectors wear a complete air respirator and perform a field test to obtain data. This simulates the scenario of an insider wearing a mask and nasal mask to verify whether clear communication can be made through the communication device; simultaneously, it simulates the inhalation and exhalation states of an insider wearing an air cylinder to verify whether clear communication can be made through the communication device.

[0004] In summary, due to the different pronunciations of different quality inspectors and the difficulty in achieving standardization, the above-mentioned testing method suffers from a low degree of standardization. Specifically, this manifests in differences in the clarity of pronunciation and the intensity of voice among different quality inspectors.

[0005] In response to the above situation, this application proposes a communication device testing system for air respirator testing instruments to improve the standardization of testing communication devices for air respirators. Summary of the Invention

[0006] To improve the standardization of testing communication devices for air respirators, this application provides a communication device testing system for air respirator testing instruments.

[0007] In a first aspect, the communication device detection system for an air respirator detector provided in this application adopts the following technical solution:

[0008] A communication device detection system for an air respirator detector, comprising:

[0009] A computer is used to acquire a start test command signal and issue a test command signal based on the start test command signal;

[0010] The host includes a command issuing module, an audio detection module, an artificial lung, and a pressure detection module. The command issuing module is connected to the computer and is used to receive the test command signal issued by the computer and to issue a standard audio signal based on the test command signal.

[0011] A head model is connected to the host computer. The head model includes a head model body and a head model circuit board. The head model circuit board is disposed inside the head model body. The head model circuit board is used to acquire the standard audio signal emitted by the host computer and convert the standard audio signal into a standard input audio output.

[0012] A communication device, connected to the head model and the host, is used to receive the standard input audio output by the head model, and the communication device generates a standard output audio based on the standard input audio and transmits the standard output audio to the host through the air;

[0013] The audio detection module is used to receive the standard output audio, and the audio detection module generates an audio determination signal based on the standard output audio and outputs the audio determination signal to the computer.

[0014] The artificial lung and the pressure detection module are connected by an airway. The pressure detection module is used to detect the pressure data of the artificial lung and output a pressure determination signal to the computer.

[0015] The computer calls the audio judgment signal and the pressure judgment signal obtained by the computer, and performs data analysis and standardized comparison on the audio judgment signal and the pressure judgment signal. The front-end interface of the operating software is used to display the analysis and comparison conclusions.

[0016] By adopting the above technical solution, when testing is required, the testing personnel need to wear a mask on the head mold and a standard communication device on the mask. The head mold is made in the shape of a human skull to simulate the scenario of an inside attack personnel wearing a mask and a mouth and nose mask, and to simulate the inhalation and exhalation state of an inside attack personnel wearing a gas cylinder. After the mask is properly worn, the testing personnel need to input relevant testing instructions on the front-end page of the computer. The computer will then receive the start test instruction signal and send a test instruction signal to the host based on the start test instruction signal. The host will start the test upon receiving the test instruction signal. The solution provided in this application does not require the quality inspector to speak; instead, the host emits a standard audio signal and sends the standard audio signal to the head mold circuit board in the head mold, and then... The head mold circuit board converts the audio into a standard input audio, simulating the sound of an attacker speaking through a mask. Then, the head mold circuit board outputs this standard input audio to the communication device. The communication device receives the standard input audio, converts it into a standard output audio, and transmits it through the air to the audio detection module on the host computer. The audio detection module, upon receiving the standard output audio, converts it into an audio judgment signal that the computer can use for evaluation. This audio judgment signal is then transmitted to the computer. Finally, the computer analyzes the received audio judgment signal and compares the results with standard reference data to determine the product's communication performance. Simultaneously, the testing personnel can visually view the analysis and comparison results on the computer's front-end display interface.

[0017] Therefore, the solution proposed in this application can achieve standardized testing of the aforementioned communication devices. Through standardized audio input, standardized comparison process, and standardized analysis and comparison results display, the testing of communication devices can be standardized to a greater extent, eliminating the influence of subjective factors of the testers on the test results and making the test conclusions more objective.

[0018] Optionally, the instruction issuing module includes:

[0019] A serial data interface is used to receive the test command signal sent by the computer;

[0020] A signal generator is used to emit the standard audio signal;

[0021] A control circuit, connected between the serial data interface and the signal generator, acquires the test command signal and controls the signal generator to emit the standard audio signal based on the test command signal.

[0022] By adopting the above technical solution, the host and the computer transmit signals through a serial data interface. When the tester starts the test by operating the computer, the computer will send a test command signal and transmit the test command signal to the host through the serial data interface. The host is equipped with a control circuit that can control the signal generator. When the test command signal is transmitted to the control circuit, the control circuit will control the signal generator to emit a standard audio signal with a frequency corresponding to the command.

[0023] Optionally, the head mold circuit board includes:

[0024] A communication device detection module is provided, wherein the communication device is capable of generating a wearing signal, and the communication device detection module is used to detect the wearing signal and issue a wearing completion command signal based on the wearing signal;

[0025] The standard audio source output module receives the wearing completion instruction signal and the standard audio signal, and converts the standard audio signal into a standard input audio output based on the wearing completion instruction signal.

[0026] By adopting the above technical solution, when the testing personnel wear the communication device on the head model, the wearing signal generated by the communication device will be detected by the communication device detection module. At the same time, the communication device detection module will issue a wearing completion command signal based on the wearing signal. Only when the standard sound source output module receives the above wearing completion command signal will it convert the standard audio signal sent by the above signal generator into the standard audio output of the corresponding frequency. This can avoid the situation where the audio output by the standard sound source output module is not worn on the head model, which will cause communication abnormalities. It also eliminates the impact of the testing personnel omitting this step and further standardizes the testing operation process.

[0027] Optionally, the communication device includes:

[0028] Earpiece, used to generate the wearing signal;

[0029] A microphone is used to receive the standard input audio output by the standard sound source output module;

[0030] A loudspeaker is used to amplify the standard input audio received by the microphone and generate the standard output audio, which is transmitted through the air to the audio detection module.

[0031] By adopting the above technical solution, the headset is equipped with a generator that can generate a wearing signal. When the headset is close to the communication device detection module of the head model, the wearing signal can be transmitted to the communication device detection module. The microphone is equipped with an audio receiver that can receive the standard audio generated by the standard sound source output module, and the amplifier amplifies the smaller standard audio to an intensity that can be received by the audio detection module in the host, thereby simulating the scenario where the communication device receives the voice of the attacker and transmits the sound.

[0032] Optionally, the communication device includes:

[0033] A microphone is used to receive the standard input audio output by the standard sound source output module;

[0034] The first walkie-talkie is connected to the microphone via data and is used to receive the standard input audio;

[0035] The second walkie-talkie is positioned within the detection range of the audio detection module and is used to receive the standard input audio and output the standard output audio based on the acquired standard input audio.

[0036] By adopting the above technical solution, long-distance intercom also plays an important role in disaster relief. After the microphone receives the standard audio, it will transmit the standard audio to the first intercom via data transmission to simulate the scenario of an insider using an intercom to speak. It is worth mentioning that at this time, the insider needs to press and hold the intercom start button. In order to simulate intercom, the tester needs to press the talk button of the first intercom while operating the computer to send the above test command signal and perform the above steps. After the first intercom transmits the first input audio to the second intercom, the second intercom will output the corresponding standard output audio to the audio detection module close to the second intercom.

[0037] Optionally, the pressure detection module includes:

[0038] A high-pressure detection unit is used to acquire a high-pressure signal from an external gas source and output a high-pressure determination signal to the computer based on the high-pressure signal.

[0039] The medium-pressure detection unit is used to acquire a medium-pressure signal from an external air source and output a medium-pressure determination signal to the computer based on the medium-pressure signal.

[0040] A low-pressure detection unit is used to acquire low-pressure signals from the artificial lung and output a low-pressure determination signal to the computer based on the low-pressure signals.

[0041] By adopting the above technical solution, this application integrates the detection of communication devices with the detection of pressure performance, realizing the integration of detection equipment. Furthermore, the detection dimensions are divided into high pressure, medium pressure, and low pressure detection, enabling more comprehensive detection functions to be achieved by utilizing the pressure detection module in the host.

[0042] Optionally, the host also includes a signal acquisition card, through which the audio determination signal, high voltage determination signal, medium voltage determination signal and low voltage determination signal are all transmitted to the computer.

[0043] By adopting the above technical solution, the host transmits the above signals to the computer through the signal acquisition card to complete the subsequent data calculation and data analysis, and further realizes the integration and unification of traditional pressure signal detection and the communication equipment detection provided in this application.

[0044] Optionally, the operating software generates a detection pattern and a detection data table based on the audio judgment signal. The operating software compares the detection pattern with a standard pattern and the detection data table with a standard data table, and generates an analysis conclusion based on the comparison results. The display interface of the operating software shows the detection pattern, the standard pattern, the detection data table, the standard data table, and the conclusion of the comparison analysis.

[0045] By adopting the above technical solution, the computer can be equipped with standard graphics and charts for comparison, which can be manually input by the testing personnel. After the host computer inputs the data signal to be tested, the computer can calculate and analyze the input data signal according to the preset algorithm and generate corresponding comparison graphics and charts. Next, the computer will compare the comparison graphics with the standard graphics according to the preset comparison method, and analyze the comparison results to find the causes of the differences and preliminary solutions. The comparison conclusions are then presented on the operation interface of the software for the testing personnel to refer to. Furthermore, the standard graphics and charts can be input and modified by the testing personnel through the computer software, making them more flexible and adaptable to different scenarios.

[0046] Optionally, the computer can acquire a repeat test instruction signal and issue a test instruction signal based on the repeat test instruction signal.

[0047] By adopting the above technical solution, when the testing personnel need to repeatedly test the same set of communication devices, they can directly send a repeat test command signal to the computer. The computer will repeatedly send test command signals to support the repeated operation of the above steps. Therefore, repeated testing can make the test results more realistic and objective, further reduce the impact of interference factors on the test results, and further improve the standardization of the testing process.

[0048] Secondly, this application provides a method for using a communication device detection system for an air respirator detector, comprising the following steps:

[0049] The head model acquires the wearing signal generated by the mask and the wearing signal generated by the communication device to determine whether the assembly is complete, and sends an assembly completion message to the computer based on the determination result.

[0050] The computer's front-end page acquires the instruction information input by the testing personnel and generates a start test instruction signal, and sends a test instruction signal to the host via a serial data interface based on the start test instruction signal;

[0051] The PLC control circuit in the host computer acquires the test command signal and sends out a standard audio signal of 10000Hz / 85dB.

[0052] The communication device detection module detects the wearing signal of the communication device, and the communication device detection module will issue a wearing completion command signal based on the wearing signal;

[0053] The standard audio signal is sent to the head mold circuit board in the head mold, and then converted into standard input audio by the standard sound source output module and output.

[0054] The microphone's audio receiver receives the standard input audio, and the amplifier amplifies the standard input audio to an intensity that can be received by the audio detection module in the host, and outputs it as the standard output audio.

[0055] The audio detection module receives the standard output audio, converts the standard output audio into an audio judgment signal for the computer to make a judgment, and transmits it to the computer.

[0056] The operating software generates detection graphics and detection data tables based on audio judgment signals, compares the detection graphics with standard graphics and the detection data tables with standard data tables, and generates analysis conclusions based on the comparison results.

[0057] The operating software's display interface shows the detection graphics, standard graphics, detection data tables, standard data tables, and comparative analysis conclusions, thus enabling the assessment of the product's communication performance.

[0058] In summary, this application includes at least one of the following beneficial technical effects:

[0059] 1. The solution proposed in this application enables standardized testing of the aforementioned communication devices. Through standardized audio input, standardized comparison process, and standardized analysis and comparison results display, the testing of communication devices is standardized to a greater extent, eliminating the influence of subjective factors of the testing personnel on the test results and making the test conclusions more objective.

[0060] 2. Only after the standard sound source output module receives the above-mentioned wearing completion instruction signal will it convert the standard audio signal sent by the above-mentioned signal generator into the standard audio output of the corresponding frequency. This can avoid the situation where the audio output by the standard sound source output module is not worn on the head model, which may cause communication abnormalities. It also eliminates the impact of the tester omitting this step and further standardizes the test operation process.

[0061] 3. The solution provided in this application supports communication performance testing for walkie-talkies, expanding the dimensions of communication equipment testing.

[0062] 4. This application integrates the detection of communication devices with the detection of pressure performance, realizing the integration of detection equipment.

[0063] 5. Compare the graphic chart to be tested with the preset standard graphic chart, and analyze the comparison results to find the causes of the differences and preliminary solutions. Present the comparison conclusions on the operation interface of the above-mentioned software for easier reference by the testing personnel. In addition, the standard graphic chart can be input and modified by the testing personnel through computer software, making it more flexible and adaptable to different scenarios.

[0064] Computer support allows for repeated testing steps, resulting in more accurate and objective test results. This further reduces the impact of interfering factors on the test results and enhances the standardization of the testing process. Attached Figure Description

[0065] Figure 1 This is a connection diagram of a communication device detection system for an air respirator detector according to an embodiment of this application. Detailed Implementation

[0066] The present application will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the scope of the application.

[0067] In the following description, numerous specific details are set forth for illustrative purposes in order to provide a thorough understanding of the inventive concept. As part of this specification, some of the accompanying drawings of this disclosure are block diagrams illustrating structures and devices to avoid complicating the disclosed principles. For clarity, not all features of the actual embodiment need to be described. References to “an embodiment” or “an embodiment” in this disclosure mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in at least one embodiment, and multiple references to “an embodiment” or “an embodiment” should not be construed as necessarily referring to the same embodiment.

[0068] Unless explicitly defined, the terms “a,” “an,” and “the” are not intended to refer to a singular entity, but rather to include a general category whose specific examples can be used for illustration. Therefore, the use of the terms “a” or “an” can mean any number of at least one, including “a,” “one or more,” “at least one,” and “one or more.” The term “or” means any of the options and any combination of the options, including all options unless explicitly indicated that the options are mutually exclusive. The phrase “at least one of” when combined with a list of items refers to a single item in the list or any combination of items in the list. The phrase does not require all items listed unless explicitly defined as such.

[0069] The relevant testing methods suffer from low standardization: First, due to differences in pronunciation among quality inspectors, and the difficulty in standardization, variations in pronunciation clarity, voice intensity, mask wearing methods, and operating procedures can all affect the final product quality assessment. Second, it is difficult to unify the testing methods used by different quality inspectors. There is no standardized set of regulations for testing the aforementioned communication devices, and different quality inspectors have different understandings of the testing methods for communication devices, which will also affect the product assessment results.

[0070] This application discloses a communication device detection system for an air respirator detector. (Refer to...) Figure 1 A communication device detection system for an air respirator detector includes a computer, a host computer, a head model, and a communication device. The computer is used to acquire a start test command signal and issue a test command signal based on the start test command signal. The host computer is connected to the computer and is used to receive the test command signal issued by the computer and to issue a standard audio signal based on the test command signal. The head model is connected to the host computer and is made in the shape of a human head to simulate the scenario of an inside attack personnel wearing a mask and a mouth and nose mask, and to simulate the inhalation and exhalation state of an inside attack personnel wearing an air cylinder. The head model includes a head model body and a head model circuit board. The head model circuit board is set inside the head model body and is used to acquire the standard audio signal issued by the host computer and convert the standard audio signal into a standard input audio output. The communication device is connected to the head model and the host computer and is used to receive the standard input audio output by the head model. The communication device generates a standard output audio based on the standard input audio and transmits the standard output audio to the host computer through the air.

[0071] The host computer includes a command issuing module, an audio detection module, an artificial lung, and a pressure detection module. The command issuing module is connected to the computer and is used to receive test command signals issued by the computer and to issue standard audio signals based on the test command signals. The audio detection module is used to receive standard output audio and to generate an audio judgment signal based on the standard output audio and output the audio judgment signal to the computer. The artificial lung and the pressure detection module are connected in the airway. The pressure detection module is used to detect the pressure data of the artificial lung and to output a pressure judgment signal to the computer. The computer calls the audio judgment signal and pressure judgment signal obtained by the computer and performs data analysis and standardized comparison on the audio judgment signal and pressure judgment signal. The front-end interface of the operating software is used to display the analysis and comparison conclusions.

[0072] When testing is required, the testing personnel need to wear the mask on the head mold and the standard communication device on the mask. After the mask is properly worn, the testing personnel need to input the relevant testing commands on the computer's front-end page. The computer will then receive the start test command signal and send a test command signal to the host based on the start test command signal. The host will start the test upon receiving the test command signal. The solution provided in this application does not require the quality inspector to speak; instead, the host sends a standard audio signal to the head mold circuit board in the head mold, which converts it into standard input audio, simulating the situation of an inside attack personnel speaking through the mask. Subsequently... The head mold circuit board outputs the standard input audio to the communication device. After receiving the standard input audio, the communication device converts it into a standard output audio and transmits it through the air to the audio detection module on the host. After receiving the standard output audio, the audio detection module converts the received audio into an audio judgment signal that can be used by the computer to make a judgment, and transmits the audio judgment signal to the computer. Finally, the computer performs data analysis on the received audio judgment signal, compares the analysis results with standard reference data, and thus completes the judgment of the product's communication performance. At the same time, the testing personnel can intuitively see the above analysis and comparison results on the front-end display interface of the computer.

[0073] Therefore, the solution proposed in this application can achieve standardized testing of the aforementioned communication devices. Through standardized audio input, standardized comparison process, and standardized analysis and comparison results display, the testing of communication devices can be standardized to a greater extent, eliminating the influence of subjective factors of the testers on the test results and making the test conclusions more objective.

[0074] For the aforementioned standard audio signal, in different embodiments, different frequency audio signals can be set as the standard audio signal for different scenarios. The tester can set this through computer software, and then the computer transmits the preset data to the host through the aforementioned test command signal. The host then sends out the standard audio signal of the preset frequency. For example, for the testing of different scenarios and different components of the communication device, the standard audio can be: a 10000Hz / 85dB audio signal for power-on testing of the communication device; and a 20Hz / 85dB-20000Hz / 85dB audio signal for performance testing of the communication device.

[0075] For the data analysis and standardized comparison of the above detection results, different directions can be taken in different embodiments. This application specifically, but not in a limited way, proposes a comparison scheme in which the operating software generates detection graphics and detection data tables based on audio judgment signals, compares the detection graphics with standard graphics and the detection data tables with standard data tables, and generates analysis conclusions based on the comparison results. The display interface of the operating software shows the detection graphics, standard graphics, detection data tables, standard data tables, and the conclusions of the comparison analysis.

[0076] Specifically, the computer allows inspectors to manually input standard graphics and charts for comparison. After the host computer inputs the data signal to be tested, it can calculate and analyze the input data signal according to a preset algorithm, and generate corresponding comparison graphics and charts. Next, the computer will compare the comparison graphics with the aforementioned standard graphics according to a preset comparison method, and analyze the comparison results to determine the causes of differences and preliminary solutions. These results are then presented as comparison conclusions on the operating interface of the software for inspectors' reference. Furthermore, the standard graphics and charts can be input and modified by inspectors through the computer software, making them more flexible and adaptable to different scenarios.

[0077] Specifically, in different embodiments, the data connection between the host and the computer can be implemented in different ways, and the host can generate and send the above-mentioned standard audio signal in different ways. This application specifically, but not in a limited way, provides a solution in which the host includes a serial data interface, a signal generator, and a control circuit. The serial data interface is used to receive test command signals sent by the computer, the signal generator is used to send standard audio signals, and the control circuit is connected between the serial data interface and the signal generator to acquire the test command signals and control the signal generator to send standard audio signals based on the test command signals.

[0078] In the above scheme, the host computer and the computer transmit signals via a serial data interface. When the testing personnel operate the computer to start the test, the computer will issue a test command signal and transmit it to the host computer via the serial data interface. The host computer is equipped with a control circuit that can control the signal generator. When the test command signal is transmitted to the control circuit, the control circuit will control the signal generator to emit a standard audio signal with a frequency corresponding to the command. In different embodiments, the control circuit can operate in different ways. As an example, a PLC control circuit can be used to control the signal generator to generate the standard audio signal required for the test.

[0079] Specifically, in different embodiments, the head mold circuit board can have different functions. In addition to receiving the above-mentioned standard audio signal, it can also have functions such as detecting the wearing status of the mask and detecting the wearing status of the communication device. This application specifically, but not limitedly, provides a composition structure and function of a head mold circuit board. The head mold circuit board includes a communication device detection module and a standard sound source output module. As a prerequisite, the above-mentioned communication device can generate a wearing signal. The communication device detection module is used to detect the wearing signal and issue a wearing completion command signal based on the wearing signal. The standard sound source output module receives the wearing completion command signal and the standard audio signal, and converts the standard audio signal into a standard input audio output based on the wearing completion command signal.

[0080] Regarding the head mold circuit board in the above solution, when the tester wears the communication device on the head mold, the wearing signal generated by the communication device will be detected by the communication device detection module. At the same time, the communication device detection module will issue a wearing completion command signal based on the wearing signal. Only when the standard sound source output module receives the above wearing completion command signal will it convert the standard audio signal sent by the above signal generator into the standard audio output of the corresponding frequency. This can avoid the situation where the audio output by the standard sound source output module causes communication abnormalities because the communication device is not worn on the head mold, eliminate the impact of the tester missing this step, and further standardize the test operation process.

[0081] Furthermore, regarding the above-mentioned solution, in different embodiments, the communication device can be composed of different structures, and the communication device can generate the above-mentioned wearing signal for detection by the communication device detection module using different structures. This application specifically, but not in a limited way, provides a solution in which the communication device includes an earpiece, a microphone, and a loudspeaker. The earpiece is used to generate a wearing signal, the microphone is used to receive the standard input audio output by the standard sound source output module, and the loudspeaker is used to amplify the standard input audio received by the microphone and generate a standard output audio. The standard output audio is transmitted through the air to the audio detection module.

[0082] In the above scheme, during the detection of the communication device, the headset is equipped with a generator that can generate a wearing signal. When the headset is close to the communication device detection module of the head model, the wearing signal can be transmitted to the communication device detection module. The microphone is equipped with an audio receiver that can receive the standard audio generated by the standard sound source output module, and the amplifier amplifies the smaller standard audio to an intensity that can be received by the audio detection module in the host, thereby simulating the scenario where the communication device receives the voice of the attacker and transmits the sound.

[0083] In response to the above solution, since long-distance intercom communication also plays an important role in disaster relief, this application proposes another communication device to describe the detection process of intercom communication in the detection system of this application. The communication device includes a microphone, a first intercom, and a second intercom. The microphone is used to receive the standard input audio output by the standard sound source output module. The first intercom is connected to the microphone via data and is used to receive the standard input audio. The second intercom is set within the detection distance range of the audio detection module and is used to receive the standard input audio and output standard output audio based on the acquired standard input audio.

[0084] The testing process for the communication equipment composed of the above scheme is as follows: after the microphone receives the standard audio, it will transmit the standard audio to the first walkie-talkie via data transmission to simulate the scenario of an insider using a walkie-talkie to speak. It is worth mentioning that at this time, the insider needs to press and hold the talk button. In order to simulate the talk, the tester needs to operate the computer to send the above test command signal while pressing the talk button of the first walkie-talkie and perform the above steps. The method of using the talk button is to press the talk button and hold it down. The sound near the first walkie-talkie will be transmitted into the walkie-talkie and transmitted to the corresponding receiving walkie-talkie through the communication device. That is, after the first walkie-talkie transmits the first input audio to the second walkie-talkie, the second walkie-talkie will output the corresponding standard output audio to the audio detection module near the second walkie-talkie. It is also worth mentioning that the above "near" means within the detection distance range of the audio detection module. This application specifically, but not limitedly, provides an example where the above "detection range" is 5cm.

[0085] As a supplement, the pressure detection module includes a high-pressure detection unit, a medium-pressure detection unit, and a low-pressure detection module. The high-pressure detection unit acquires a high-pressure signal from an external air source and outputs a high-pressure determination signal to the computer based on the high-pressure signal. The medium-pressure detection unit acquires a medium-pressure signal from an external air source and outputs a medium-pressure determination signal to the computer based on the medium-pressure signal. The low-pressure detection unit acquires a low-pressure signal from the artificial lung and outputs a low-pressure determination signal to the computer based on the low-pressure signal. This application integrates the detection of the communication device with the detection of pressure performance, realizing the integration of the detection equipment. Furthermore, the detection dimensions are divided into high-pressure, medium-pressure, and low-pressure detection, enabling more comprehensive detection functions to be achieved using the pressure detection module in the host unit.

[0086] To enable the aforementioned signals to be uniformly transmitted from the host to the computer for further calculation and analysis, the host also includes a signal acquisition card. The audio judgment signal, high pressure judgment signal, medium pressure judgment signal, and low pressure judgment signal are all transmitted to the computer through the signal acquisition card, further realizing the integration and unification of traditional pressure signal detection with the communication equipment detection provided in this application.

[0087] As a supplement, in the proposed solution, the computer can acquire repeat test command signals and issue test command signals based on these signals. When the testing personnel need to perform repeated tests on the same communication device, they can directly send repeat test command signals to the computer. The computer will then repeatedly issue test command signals to support the repeated operation of the above steps. Therefore, repeated testing can make the test results more realistic and objective, further reduce the impact of interference factors on the test results, and further improve the standardization of the testing process.

[0088] In summary, the specific detection method of the communication device detection system for an air respirator detector proposed in this application is as follows:

[0089] First, the testing personnel need to wear the mask on the head model and the standard communication device on the mask. After the mask is properly worn, the testing personnel need to input the relevant testing instructions on the front page of the computer. The computer will then receive the start test instruction signal and send a test instruction signal to the host based on the start test instruction signal.

[0090] Subsequently, the computer will send a test command signal and transmit it to the host computer via a serial data interface. The host computer is equipped with a PLC control circuit that can control the signal generator. After the test command signal is transmitted to the control circuit, the control circuit will control the signal generator to emit a standard audio signal of 10000Hz / 85dB.

[0091] At this time, the wearing signal generated by the communication device will be detected by the communication device detection module, and the communication device detection module will issue a wearing completion command signal based on the wearing signal.

[0092] Subsequently, the standard audio signal is sent to the head mold circuit board in the head mold, and then converted into standard input audio by the standard sound source output module before being output.

[0093] Subsequently, the audio receiver in the microphone can receive the standard input audio generated by the standard sound source output module, and the amplifier amplifies the smaller standard audio to an intensity that can be received by the audio detection module in the host, and outputs it as the standard output audio to the audio detection module.

[0094] Next, after receiving the standard output audio, the audio detection module can convert the received audio into an audio judgment signal that can be used by the computer to make a judgment, and then transmit the audio judgment signal to the computer.

[0095] Finally, the operating software generates detection graphics and detection data tables based on the audio judgment signal. The operating software compares the detection graphics with standard graphics and the detection data tables with standard data tables, and generates analysis conclusions based on the comparison results. The operating software's display interface shows the detection graphics, standard graphics, detection data tables, standard data tables, and the conclusions of the comparative analysis, thus completing the judgment of the product's communication performance. At the same time, the testing personnel can intuitively see the above analysis and comparison results on the front-end display interface of the computer.

[0096] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
