Description

Technical Field

[0001] This invention relates to the field of hearing protection, and more particularly to a hearing protector, a detection system, and a monitoring method. Background Technology

[0002] Hearing protectors are personal protective equipment designed to protect the auditory organs from damage caused by excessive environmental noise. They prevent hearing loss, tinnitus, and other hearing-related problems by reducing the level of noise entering the ear and minimizing noise exposure. These devices are mainly categorized into earplugs, earmuffs, and noise-canceling helmets. Earplugs are typically inserted into the external auditory canal, while earmuffs cover the ears and may be connected to a headband; they attenuate noise by isolating or absorbing sound energy. The performance of hearing protectors is commonly measured by noise reduction ratios (such as NRR), but the actual effect is affected by factors such as wearing method and ear canal structure, and may be lower than the laboratory-rated value. Using hearing protectors is particularly important for groups with long-term exposure to high-noise environments (in industrial production, construction, aerospace, and other high-noise environments, employees are highly susceptible to hearing damage due to prolonged exposure to high decibel noise, thus requiring hearing protectors to protect their hearing), as it reduces the risk of inner ear structural damage and indirectly improves work safety and efficiency. Proper selection and wearing (such as fitting according to noise characteristics) are crucial to ensuring protective effectiveness. Customized hearing protectors, such as earplugs, offer superior comfort and a good seal; however, they still have the following drawbacks: 1. Limited and unreliable methods for verifying wearing status: Traditional in-ear detection relies heavily on simple contact or temperature sensors, which are easily circumvented. For example, employees may wear the earphone briefly during the inspection and immediately remove it afterward, putting it in their pocket or hand, failing to ensure effective protection throughout the entire noise exposure period. 2. Lack of real-time noise reduction effect evaluation capability: Most existing hearing protectors are passive sound insulation devices, which cannot monitor the actual noise intensity in the ear canal in real time, making it difficult to quantify their noise reduction efficiency and ensure that they meet sufficient protection standards in specific environments. 3. Outdated management methods: Safety management still relies on manual inspections and paper records, which is inefficient and cannot achieve real-time supervision and precise management with full coverage of all personnel, all time periods, and all areas. It is also difficult to dynamically link the wearing requirements with specific personnel, positions, and noisy areas.

[0003] Therefore, solving the above-mentioned technical problems is a direction that those skilled in the art need to strive for. Summary of the Invention

[0005] The purpose of this invention is to provide a hearing protector, a detection system, and a monitoring method. By using this protector, the effectiveness and protective effect of hearing protection can be effectively guaranteed.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a hearing protector, comprising a bioimpedance sensor, a pressure sensor, a power supply component, and a data transmission module installed within the hearing protector; The power supply component provides power to the impedance sensor, pressure sensor, and data transmission module; The impedance sensor is used to detect the bioelectric properties of the skin and transmit the detected signal to the data transmission module. The pressure sensor is used to detect the pressure value felt by the hearing protector and transmit the detected signal to the data transmission module. The data transmission module is used to transmit the detected signal and / or to receive the signal.

[0007] In the above technical solution, the hearing protector is also equipped with a bone vibration sensor. The power supply component provides power to the bone vibration sensor, which is used to detect physiological signals and transmit the detected signals to the data transmission module.

[0008] In the above technical solution, an infrared proximity sensor is also installed inside the hearing protector. The power supply component provides power to the infrared proximity sensor. The infrared proximity sensor is used to detect whether there is an object at the first end of the hearing protector and transmits the detected signal to the data transmission module.

[0009] In the above technical solution, the hearing protector is further equipped with a first microphone and a second microphone electrically connected to the data transmission module. The power supply component provides power to the first microphone and the second microphone. The first microphone is used to detect noise and / or sound pressure at the first end of the hearing protector, and the second microphone is used to detect noise and / or sound pressure at the second end of the hearing protector, and transmits the detected signal to the data transmission module.

[0010] In the above technical solution, the first microphone is used to detect the sound pressure in the ear canal between the first end of the hearing protector and the eardrum, and the second microphone is used to detect the noise and / or sound pressure of the external environment of the ear canal.

[0011] In the above technical solution, the hearing protector is also equipped with an alarm mechanism, which is electrically connected to the power supply component and the data transmission module. And / or, the hearing protector is also equipped with a switch.

[0012] The present invention also provides a hearing protection monitoring system, including the aforementioned hearing protector and a monitoring platform. The data transmission module is used to transmit the detected signal to the monitoring platform, and the monitoring platform is used to analyze and process the received signal from the hearing protector.

[0013] The above technical solution also includes a management terminal, through which the monitoring platform displays and / or alarms the received signal information of the hearing protector that has been processed.

[0014] The above technical solution also includes a client, through which the monitoring platform displays and / or alarms the received signal information from the hearing protector that has been processed.

[0015] This invention also provides a hearing protection monitoring method, which uses the above-mentioned hearing protection monitoring system, and the steps are as follows: S1. Turn on the hearing protector to activate all components inside, and then wear the hearing protector. S2. The hearing protector is tested through its internal components, and the detected signal is transmitted to the monitoring platform via the data transmission module. The monitoring platform analyzes and processes the signal to determine whether the hearing protector is worn correctly and / or whether the noise reduction is up to standard.

[0016] In the above technical solution, step S2, determining whether the hearing protector is worn correctly, includes the following steps: A1. The bioimpedance sensor inside the hearing protector detects whether the hearing protector has detected human skin and transmits the detection signal to the monitoring platform. The monitoring platform makes a judgment. If human skin is not detected, the hearing protector is not worn correctly or is not being worn. If human skin is detected, it is preliminarily determined that the hearing protector is in contact with the human body. A2. The pressure sensor inside the hearing protector detects the pressure value and transmits the detection signal to the monitoring platform. The monitoring platform judges whether it is within the normal wearing pressure range. If it is not within the wearing pressure range, the hearing protector is not worn correctly or not worn at all. If the pressure value is within the correct wearing pressure range and the bioimpedance sensor is in contact with the human skin, the hearing protector is judged to be worn correctly.

[0017] In the above technical solution, step S2, checking whether the hearing protector is worn correctly, further includes the following steps: B1. The bone vibration sensor inside the hearing protector detects whether there is a physiological signal and transmits the detected signal to the monitoring platform. The monitoring platform judges whether a physiological signal has been detected. If no physiological signal is detected, the hearing protector is not worn correctly or is not worn at all. If a physiological signal is detected and the bioimpedance sensor is in contact with the human skin and the pressure value is within the range of correct wearing, then the hearing protector is judged to be worn correctly.

[0018] In the above technical solution, step S2, checking whether the hearing protector is worn correctly, further includes the following steps: C1. The infrared proximity sensor inside the hearing protector detects whether there is an obstacle at the first end of the hearing protector and transmits the detected signal to the monitoring platform. The monitoring platform judges whether an obstacle has been detected. If no obstacle is detected, the hearing protector is not worn correctly or not worn at all. If an obstacle is detected, and the bioimpedance sensor is in contact with the human skin with a pressure value within the correct wearing range, and physiological signals are detected, then the hearing protector is judged to be worn correctly.

[0019] In the above technical solution, step S2, determining whether the noise reduction of the hearing protector is qualified, includes the following steps: D1. The first and second microphones inside the hearing protector detect the noise and / or sound pressure at the first end and the second end of the hearing protector, respectively, and transmit the detected signals to the monitoring platform. The monitoring platform calculates whether the pressure difference between the two is within the preset pressure difference range. If the pressure difference is not within the preset pressure difference range, the noise reduction is unqualified, and it is determined that there is a problem with the hearing protection of the hearing protector; if the pressure difference is within the preset pressure difference range, the noise reduction is qualified, and it is determined that the hearing protection of the hearing protector is effective.

[0020] The above technical solution also includes step S3, whereby the monitoring platform judges the monitoring information of the corresponding hearing protector and displays and / or alarms it through the management terminal and / or client and / or hearing protector.

[0021] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: 1. In this invention, an impedance sensor detects whether there is contact with the human body, a pressure sensor detects the pressure value, and a data transmission module transmits the detected data to a monitoring platform. The monitoring platform analyzes and processes the data to determine whether the user is wearing the hearing protector correctly, thereby reminding managers or users to wear the hearing protector correctly to ensure the correct wearing of the hearing protector, prevent hearing damage, and effectively improve the protective effect and hearing protection effect of the hearing protector during use. 2. The present invention also includes a bone vibration sensor for detecting physiological signals, which is cross-validated with impedance and pressure sensors to determine whether the user is wearing the hearing protector correctly, thereby effectively ensuring the effectiveness and protective effect of the user's hearing protection. 3. The present invention also includes an infrared proximity sensor to detect the distance between the hearing protector and the inside of the ear canal, and cross-verifies the detection signals with other sensors to further determine whether the user is wearing the hearing protector correctly, thus ensuring the effectiveness and efficacy of hearing protection. 4. The present invention also includes two microphones for detecting the sound pressure at both ends of the hearing protector. By comparing the sound pressure difference between the two microphones with a preset sound pressure difference, the noise reduction effect is determined, thereby determining the wearing effect or noise reduction effect of the hearing protector and ensuring the effectiveness and protective effect of hearing protection. 5. In this invention, the monitoring platform monitors the operating status and protection status of all hearing protectors within a preset range, and can display the status in real time through the client, user terminal, and hearing protector. This enables effective dynamic management, effectively determines whether the corresponding user is wearing and using the hearing protector correctly, ensures the hearing protection effect of the user, and prevents the user's hearing damage.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: See Figure 1-3 As shown, a hearing protector includes a bioimpedance sensor, a pressure sensor, a power supply component, and a data transmission module installed within the hearing protector. The power supply component provides power to the impedance sensor, pressure sensor, and data transmission module; The impedance sensor is used to detect the bioelectric properties of the skin and transmit the detected signal to the data transmission module. The pressure sensor is used to detect the pressure value felt by the hearing protector and transmit the detected signal to the data transmission module. The data transmission module is used to transmit the detected signal and / or to receive the signal.

[0024] The present invention also provides a hearing protection monitoring system, including the aforementioned hearing protector and a monitoring platform. The data transmission module is used to transmit the detected signal to the monitoring platform, and the monitoring platform is used to analyze and process the received signal from the hearing protector.

[0025] The monitoring platform can be a combination of a computer, gateway device, and positioning base station, or a combination of a cloud platform, gateway device, and positioning base station. Preferably, the monitoring platform uses a combination of a cloud platform, gateway device, and positioning base station. Of course, positioning base stations can also be omitted; for example, a computer can be used. The computer is a local computer that only receives local data (for example, if the hearing protector is used in a factory area, the computer will only receive the detection signals / data of all hearing protectors in that factory area, so a positioning base station is not needed). If a cloud platform is used, it needs to process data from many locations, so it is best to use a positioning base station to locate the location range of the corresponding hearing protector, such as the corresponding factory area. The data transmission module is a wireless data transmission module, which can be a UWB module with positioning function, Bluetooth module, Wi-Fi module, 3G module, 4G module, 5G module, 6G module, or LoRa, etc. Bluetooth module is preferred. The power supply component is preferably a battery, which can be a non-rechargeable battery or a rechargeable battery. All sensors, data transmission modules, and other components in the hearing protector are low-power components with low power consumption.

[0026] Preferably, the hearing protector is an earbud-type hearing protector. When in use, the hearing protector is worn (inserted into the ear canal). The internal sensors work and detect signals, transmitting the detected signals (signal data) through a data transmission module. A gateway device receives signals from all hearing protectors within its range. If the corresponding data transmission module also contains location information, it will receive the location information through a positioning base station and transmit the information to a cloud platform through the gateway device. The cloud platform analyzes and processes the signal data detected by the hearing protector and determines whether the hearing protector is worn correctly.

[0027] After the monitoring platform analyzes and processes the data from the hearing protector, it is also necessary to display or show the status of the hearing protector so that users or managers can promptly identify problems. Therefore, further, it also includes a management terminal, through which the monitoring platform displays and / or alarms the processed and received signal information from the hearing protector.

[0028] The management terminal includes one or all of the following: a field monitoring terminal, a mobile app, and a web-based management backend. The field monitoring terminal can be used in situations where hearing protectors are used, such as in a workshop. It can be a display screen or other display device. For example, the screen might display the name of the user currently using a hearing protector, or the name or number of someone in the workshop who needs to use a hearing protector. Gray text indicates the hearing protector is not in use, green text indicates it is being worn correctly, and red text indicates it is not being worn correctly. Workshop management personnel can then promptly manage and correct this until it is worn correctly. After successful wearing, the text will turn green (this is one method; other display methods are also possible, such as displaying "qualified" or "unqualified," etc.). The mobile app is installed on a mobile phone or a dedicated handheld device. The monitoring platform pushes notifications of whether hearing protectors are valid or not to the mobile app. Managers can then observe the effectiveness and compliance of the hearing protectors worn by the corresponding personnel through the mobile app. For those wearing non-compliant protectors, they can be directly informed to correct the issue. Of course, if managers do not check the mobile app in a timely manner, it can also issue an alarm (for those wearing non-compliant protectors). The web management backend can be a computer or a large display screen, placed in the usage environment for monitoring by all personnel. It can also statistically analyze hearing protector wearing status and generate reports for subsequent traceability and archiving.

[0029] Ideally, the monitoring platform includes a positioning base station covering the area where hearing protectors are mandatory. Once the hearing protector enters this area, it connects to the monitoring platform via a data transmission module. The platform uses signals detected by its internal sensors to determine whether the hearing protector is being worn correctly. In areas where hearing protector use is not mandatory, users are not required to wear them, and administrators can choose not to enforce it.

[0030] Furthermore, it also includes a client application, through which the monitoring platform displays and / or alerts the received hearing protector signal information that has been processed.

[0031] The client can be a mobile phone, handheld client, mobile APP, or other type of device that can be placed directly on the user wearing the hearing protector. For example, if the client is a mobile phone, it can be placed directly on the user's body. If the user is not wearing the hearing protector properly or correctly, the monitoring platform will notify the user directly on the mobile phone via SMS or VoIP to remind the user that the hearing protector is not being worn correctly.

[0032] Furthermore, the hearing protector is also equipped with an alarm mechanism, which is electrically connected to the power supply component and the data transmission module.

[0033] The alarm mechanism can be an audible and visual alarm module, either a sound alarm module or a photoelectric alarm module. For example, an audible and visual alarm module includes a buzzer and LEDs. If the hearing protector is not worn correctly, the monitoring platform can send control data back to the hearing protector via a data transmission module, triggering the buzzer and activating the LEDs to remind the user or administrator to wear the hearing protector correctly. If it is already worn correctly, the alarm mechanism will not trigger a new alarm.

[0034] This invention also provides a hearing protection monitoring method, which uses the above-mentioned hearing protection monitoring system, and the steps are as follows: S1. Turn on the hearing protector to activate all components inside, and wear the hearing protector. The hearing protector is also equipped with a switch, which can be a touch switch that is turned on when touched. S2. The hearing protector is tested through its internal components, and the detected signal is transmitted to the monitoring platform through the data transmission module. The monitoring platform analyzes and processes the signal to determine whether the hearing protector is worn correctly and / or whether the noise reduction is qualified. S3. After judging the monitoring information of the corresponding hearing protector, the monitoring platform will display and / or alarm through the management terminal and / or client and / or hearing protector.

[0035] In step S2, determining whether the hearing protector is worn correctly includes the following steps: A1. The bioimpedance sensor inside the hearing protector detects whether the hearing protector has detected human skin and transmits the detection signal to the monitoring platform. The monitoring platform makes a judgment. If human skin is not detected, the hearing protector is not worn correctly or is not being worn. If human skin is detected, it is preliminarily determined that the hearing protector is in contact with the human body. A2. The pressure sensor inside the hearing protector detects the pressure value and transmits the signal to the monitoring platform. The monitoring platform then determines whether the pressure is within the normal wearing pressure range. If the pressure is outside the range, the hearing protector is not worn correctly or not at all. If the pressure is within the correct range and the bioimpedance sensor is in contact with the skin, the hearing protector is considered to be worn correctly. The pressure value detected by the pressure sensor can be used to determine the fit between the hearing protector and the ear canal, and this value is cross-validated with the bioimpedance sensor's detection to determine whether the hearing protector is worn correctly.

[0036] In this approach, the monitoring platform needs to cross-verify the detection signals from the bio-blocking sensor and the pressure sensor to determine whether the hearing protector is being worn correctly, thus preventing deception.

[0037] Furthermore, in order to improve the monitoring effect and accuracy of whether the hearing protector is worn correctly, a bone vibration sensor is also installed in the hearing protector. The power supply component provides power to the bone vibration sensor, which is used to detect physiological signals and transmit the detected signals to the data transmission module.

[0038] Therefore, in step S2, determining whether the hearing protector is worn correctly also includes the following steps: B1. The bone conduction sensor inside the hearing protector detects the presence of physiological signals and transmits these signals to a monitoring platform. The platform then determines whether a physiological signal has been detected. If no physiological signal is detected, the hearing protector is not worn correctly or is not being worn at all. If a physiological signal is detected, and the bioimpedance sensor is in contact with the skin with pressure within the correct wearing range, the hearing protector is considered to be worn correctly. See the flowchart. Figure 2 As shown.

[0039] In this approach, in addition to bioimpedance sensors and pressure sensors, a bone vibration sensor is also set up to detect physiological signals. The three are combined and cross-validated to further verify the accuracy of whether the hearing protector is worn correctly.

[0040] Furthermore, to improve the monitoring effect and accuracy of whether the hearing protector is worn correctly, an infrared proximity sensor is also installed inside the hearing protector. The power supply component provides power to the infrared proximity sensor, which is used to detect whether there is an object at the first end of the hearing protector and transmits the detected signal to the data transmission module.

[0041] In this embodiment, the first end is located inside the hearing protector, and the second end is located outside the hearing protector. After the hearing protector is worn into the ear canal, the first end is inside the ear canal, and the second end is outside the ear canal, or directly opposite the outside of the ear canal.

[0042] In step S2, determining whether the hearing protector is worn correctly also includes the following steps: C1. The infrared proximity sensor inside the hearing protector detects whether there is an obstacle at the first end of the hearing protector and transmits the detected signal to the monitoring platform. The monitoring platform judges whether an obstacle has been detected. If no obstacle is detected, the hearing protector is not worn correctly or not worn at all. If an obstacle is detected, and the bioimpedance sensor is in contact with the human skin with a pressure value within the correct wearing range, and physiological signals are detected, then the hearing protector is judged to be worn correctly.

[0043] In this method, after the hearing protector is inserted into the ear canal, the first end faces the ear canal tissue, such as the eardrum. It can detect the proximity or presence of any object (such as ear canal tissue) in front of it through an infrared proximity sensor. This signal data is used as an independent signal. After the bioimpedance sensor confirms contact with the human body, it is cross-validated with one or all of the detection signals from the pressure sensor, bone vibration sensor, and infrared proximity sensor (the detection signals from the pressure sensor, bone vibration sensor, and infrared proximity sensor are all within a preset range). Together, they form a multi-sensor fusion judgment logic. When the preset "correct wearing" model is met, the monitoring platform can finally determine that it is correctly worn. This can effectively avoid the possibility of being deceived by relying too much on a single sensor (such as misjudgment due to the hearing protector coming into contact with other objects).

[0044] Furthermore, the above method is only used to determine whether the hearing protector is worn correctly. However, even if it is worn correctly, there may still be problems, and the protective effect of the hearing protector cannot be determined. Therefore, a first microphone and a second microphone electrically connected to the data transmission module are also installed in the hearing protector. The power supply component provides power to the first microphone and the second microphone. The first microphone is used to detect noise and / or sound pressure at the first end of the hearing protector, and the second microphone is used to detect noise and / or sound pressure at the second end of the hearing protector, and transmits the detected signal to the data transmission module.

[0045] The first microphone is used to detect the sound pressure in the ear canal between the first end of the hearing protector and the eardrum, and the second microphone is used to detect noise and / or sound pressure in the external environment of the ear canal.

[0046] Therefore, in this embodiment, determining whether the noise reduction of the hearing protector is qualified in step S2 includes the following steps: D1. The first and second microphones inside the hearing protector detect noise and / or sound pressure at the first and second ends of the hearing protector, respectively, and transmit the detected signals to the monitoring platform. The monitoring platform calculates whether the pressure difference between the two is within a preset pressure difference range. If the pressure difference is not within the preset range, the noise reduction is unqualified, indicating a problem with the hearing protection of the hearing protector. If the pressure difference is within the preset range, the noise reduction is qualified, indicating that the hearing protection of the hearing protector is effective. See the flowchart. Figure 3 As shown.

[0047] In this method, the first and second microphones collect noise and sound pressure signals, which are then transmitted to a monitoring platform via a data transmission module. A miniature calculator on the monitoring platform calculates parameters such as total noise reduction, attenuation values ​​for each frequency band, and fit tightness. The platform also processes the data, storing and transmitting locally cached data to the backend for further processing. The noise reduction effect is then displayed in real-time (e.g., on the management or client side) to determine if it meets the required standards. If it does not meet the standards, an alarm is triggered via the management terminal, client, or the hearing protector, prompting the user to adjust or check their hearing protector. Similarly, if the sensor detects incorrect hearing protector fit, the user must also adjust the fit.

[0048] This method can not only monitor whether the hearing protector is worn correctly, but also whether the noise reduction is up to standard, determine if there is a problem with the hearing protector and whether it needs to be replaced, and effectively protect the user's hearing.

[0049] The entire monitoring system can be divided into a perception layer, a network layer, a platform layer, and an application layer. The hearing protector and its application mode reside in the perception layer, which senses the hearing protector's application status. The network layer primarily transmits data; the gateway device and positioning base station in the monitoring platform are located within the network layer, receiving data from the hearing protector via Bluetooth and transmitting it through their data transceiver modules. The positioning base station uses the location of the hearing protector for positioning. The platform layer mainly handles data processing. The cloud platform resides in the platform layer and includes an alarm engine (equivalent to an alarm module, used to trigger alarms for abnormal states), a data receiving and parsing module (used to receive, process, and analyze signal data detected by sensors in the hearing protector), a data storage and management module (used for data storage and management), a system integration interface module (serving as a data transmission interface), and a noise map system (dividing areas requiring mandatory hearing protector use into other areas). The application layer includes management terminals, such as field monitoring terminals (real-time display in workshops and central control rooms), mobile apps, web backends, user terminals, and alarm modules for hearing protectors (some not shown in the attached diagram). See [link / reference]. Figure 1 As shown.
