Description

Technical Field

[0001] This utility model relates to the field of wireless data transmission technology, and in particular to a wireless data transmission device for electronic protective gear. Background Technology

[0002] In practical applications of combat protective gear, multiple sensors are typically required for data acquisition and transmission, while also needing to receive data commands. Although wireless transmission reduces the need for numerous cables connecting the transmitter and receiver, this very limitation presents a significant challenge: data synchronization. Therefore, the development of a wireless data transmission device for electronic protective gear is necessary.

[0003] Because there are many scoring points in Sanda (Chinese kickboxing), protective gear needs to collect sensor information from all scoring points within a certain time and simultaneously send this information to the host computer. Regardless of whether a strike occurs within this time period, due to wireless data transmission, current Sanda protective gear has problems such as inaccurate transmission of sensor information from all scoring points within a certain time and untimely data transmission. Sometimes, information from some parts may even be missing, affecting the fairness of the competition. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wireless data transmission device for electronic protective gear, which aims to improve the existing technology of Sanda protective gear, which has problems such as inaccurate transmission of sensor information of all scoring points within a certain period of time, untimely data transmission, and sometimes even missing information of some parts, affecting the fairness of the competition.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wireless data transmission device for electronic protective gear, comprising a magnetic base, multiple sensors, a data acquisition module, a signal conditioning circuit, an ADC chip, a data processing and verification module, a node wireless communication module, a multi-mode transmission module, a power supply module, a low-power control module, and a Flash storage module. The magnetic base is fixedly installed on the inner side of the electronic protective gear. The multiple sensors are arranged at various scoring points of the protective gear to collect impact sensing information. The output terminals of the multiple sensors are electrically connected to the input terminal of the signal conditioning circuit, and the output terminal of the signal conditioning circuit is electrically connected to the input terminal of the ADC chip for processing analog signals. The system performs noise reduction and amplification processing. The output of the ADC chip is electrically connected to the input of the data acquisition module to convert the processed analog signal into a digital signal. The output of the data acquisition module is electrically connected to the input of the data processing and verification module. The data processing and verification module includes a main control MCU, which receives digital signals and generates data frames with timestamps. It also performs data verification through a built-in CRC32 and logic verification unit. The Flash storage module is electrically connected to the data processing and verification module for data buffering. The node wireless communication module is electrically connected to the output of the data processing and verification module to wirelessly transmit the verified data stream to an external receiving terminal.

[0006] The above technical solution securely fixes the device to the inside of the electronic protective gear using a magnetic base, ensuring the fit between the sensor and the scoring point of the protective gear and preventing displacement during movement from affecting the acquisition accuracy. The impact signals collected by multiple sensors are uniformly transmitted to the signal conditioning circuit for noise reduction and amplification, and then converted into digital signals by the ADC chip. This signal is received by the data acquisition module and sent to the data processing and verification module. The main control MCU adds a timestamp, performs verification, and generates a secure data frame. At the same time, it interacts with the Flash storage module to achieve data caching. Finally, the processed data is wirelessly transmitted to the external receiving terminal through the node wireless communication module.

[0007] As a further description of the above technical solution: The power supply module is electrically connected to multiple sensors, signal conditioning circuits, ADC chips, data acquisition modules, data processing and verification modules, node wireless communication modules, Flash storage modules, and low-power control modules, respectively, to provide stable voltage for the operation of each module. The low-power control module is electrically connected to the data acquisition module, data processing and verification module, and node wireless communication module, respectively, to control each module to enter sleep mode when not in operation.

[0008] Through the above technical solution: the power supply module provides a stable voltage adapted to the working requirements of each module through electrical connection with multiple sensors, signal conditioning circuits, ADC chips and other full-link modules, avoiding distortion of the impact signal collected by the sensors due to voltage fluctuations, ensuring the stability and reliability of the entire process from signal acquisition to data transmission, and laying the power foundation for the device to continuously output accurate impact data. Through the electrical connection of the low-power control module with the data acquisition module, data processing and verification module and node wireless communication module, the power supply of these high-power modules can be actively cut off or controlled to enter sleep mode when the device is not in operation, which significantly reduces standby power consumption. When it is needed to work, the modules can be quickly woken up. This solves the battery life problem of electronic protective gear relying on lithium battery power supply, without affecting the real-time acquisition of impact signals, and achieves a balance between low-power standby and high-sensitivity operation.

[0009] As a further description of the above technical solution: The low-power control module includes a wake-up detection unit, which triggers the device to wake up and resume operation when the next sampling cycle or when the external power supply is interrupted. After sampling and transmission are completed, the low-power control module controls the device to enter a deep sleep mode, with only the wake-up detection unit remaining operational.

[0010] The above technical solution enables closed-loop power management of the device through the wake-up detection unit. When the next sampling cycle arrives, the wake-up detection unit can trigger the device to wake up on time, ensuring that periodic sampling is not missed. When the external power supply is interrupted and switched to lithium battery power, the device can also be woken up synchronously to avoid work interruption caused by power supply switching. After sampling and transmission are completed, the low-power control module controls the device to enter deep sleep mode, keeping only the wake-up detection unit running. This can reduce standby power consumption to the microampere level, maximize the extension of lithium battery usage time, and adapt to scenarios where protective gear is worn for a long time.

[0011] As a further description of the above technical solution: The data acquisition module includes an isolation unit connected between the ADC chip and the data processing and verification module to achieve electrical isolation protection.

[0012] Through the above technical solution: In the scenario of electronic protective gear, since the signals collected by the sensors may be affected by electromagnetic interference during movement, and the main control MCU of the data processing and verification module is a sensitive digital circuit, it is necessary to prevent noise or voltage fluctuations in the front-end analog link from being transmitted to the back-end. Therefore, by placing the isolation unit between the ADC chip and the data processing and verification module, the electrical circuit can be blocked through opto-isolation, magnetic isolation and other methods, effectively isolating the common-mode interference and differential-mode interference between the front-end analog signal link and the back-end digital processing link, protecting the core components such as the MCU from voltage spikes or surges, and improving the working stability of the device in complex electromagnetic environments. It is especially suitable for the severe vibration and interference scenarios of multiple devices working simultaneously in Sanda sports.

[0013] As a further description of the above technical solution: The main control MCU chip of the data processing and verification module is electrically connected to the isolation unit of the data acquisition module, and is used to receive digital signals transmitted through the isolation unit.

[0014] Through the above technical solution: the main control MCU chip of the data processing and verification module is directly electrically connected to the isolation unit of the data acquisition module, which can receive the digital signal after electrical isolation. In this process, the isolation unit blocks electromagnetic interference, ground potential difference and other noise from the front-end analog link, preventing these interferences from affecting the stable operation of the main control MCU through signal transmission. At the same time, the pure digital signal also provides accurate raw data for the subsequent MCU to generate data frames, perform CRC verification and encryption processing, reduce data errors caused by signal interference, and ensure that the final data transmitted to the back end is true and reliable.

[0015] As a further description of the above technical solution: The data processing and verification module includes an encryption unit, which is used to encrypt the data frame using AES-128 before transmitting it to the multimode transmission module.

[0016] The above technical solution enables medium- to long-distance data uploads via a multi-mode transmission module. This module connects directly to the data processing and verification module, allowing direct access to the final processed and valid data, avoiding data loss or delays in intermediate stages. This connection ensures that the multi-mode transmission module can stably receive verified and encrypted reliable data. Furthermore, the single link from the data processing and verification module to the multi-mode transmission module simplifies the transmission path, adhering to the principle of simplicity in modular design. Simultaneously, combined with the management of the low-power control module, power consumption and transmission requirements can be balanced, adapting to the battery life requirements of electronic protective gear.

[0017] As a further description of the above technical solution: The multi-mode transmission module includes a link detection unit, a 4G module, a PLC module, and a Bluetooth module. The 4G module takes priority in the transmission link, with the PLC module as a backup. The link detection unit monitors the 4G signal strength in real time. When the signal strength is ≥-90dBm, the 4G module uploads encrypted data frames to the power platform. When the signal strength is <-90dBm, it automatically switches to the PLC module for data transmission, using the power line to transmit the data to a nearby power acquisition terminal, which then forwards it to the platform. The Bluetooth module is only activated during on-site debugging and is used to read cached data and modify configuration parameters via a mobile app.

[0018] The above technical solution integrates a multi-mode transmission module with a link detection unit, a 4G module, a PLC module, and a Bluetooth module, constructing a transmission system that combines primary and backup capabilities with dedicated debugging. The link detection unit monitors the 4G signal strength in real time. When the signal is strong (≥-90dBm), encrypted data frames are prioritized for direct upload to the power platform via the 4G module, ensuring data real-time performance. When the signal is weak (<-90dBm), the system automatically switches to the PLC module, transmitting data via power lines to nearby power acquisition terminals and then forwarding it to the platform. This leverages the wide coverage and strong anti-interference characteristics of power lines to solve signal blind spots. The dual links ensure no data loss. The Bluetooth module is only activated during debugging, allowing for cached data reading and parameter modification via a mobile app. This approach does not consume primary transmission resources and improves on-site maintenance convenience, thus meeting the core requirement of stable data transmission to the power platform.

[0019] As a further description of the above technical solution: The power supply module includes a power switching unit, an external power supply interface, and a lithium battery. The power supply module is connected to a 220V power grid and completes lithium battery charging. When the external power supply is interrupted, the power switching unit automatically switches to lithium battery power supply to ensure uninterrupted data acquisition and storage. When the external power supply is restored, the power switching unit automatically switches back to external power supply and charges the lithium battery.

[0020] Through the above technical solution, the power supply module, in collaboration with the power switching unit, external power supply interface, and lithium battery, forms a full-scenario power supply guarantee of "main supply-backup-recovery". It connects to the 220V power grid through the external power supply interface to continuously supply power to the device and charge the lithium battery, adapting to long-term operation in fixed scenarios. When the external power supply is suddenly interrupted, the power switching unit instantly switches to lithium battery power supply to ensure that the core functions such as sensor acquisition and data storage are not interrupted and to prevent the loss of critical data. After the external power supply is restored, it automatically switches back to grid power supply and simultaneously replenishes the lithium battery to maintain the backup power endurance. The seamless switching mechanism achieves zero power supply interruption and provides reliable power support for the continuity of data acquisition and transmission.

[0021] This utility model has the following beneficial effects: 1. In this utility model, through the 4G, PLC, and Bluetooth modules of the multi-mode transmission link and the automatic link switching mechanism, the multi-mode transmission module monitors the signal in real time through the link detection unit. 4G is prioritized to ensure wide-area real-time transmission, PLC is used as a backup to solve the signal blind spot problem, and Bluetooth is used for dedicated debugging without occupying the main link. The triple link covers different scenarios, reduces the data packet loss rate, and, with the Flash caching and retransmission function, completely solves the problem of data loss caused by a single link interruption. The dual verification and encryption mechanism of the data processing and verification module ensures that the data is accurate and cannot be tampered with, thus guaranteeing the fairness of electricity billing and monitoring.

[0022] 2. In this invention, a node wireless communication module is responsible for real-time interaction between the protective gear and the local terminal, while a multi-mode transmission module is responsible for non-real-time data backup and analysis between the protective gear and the remote platform. Together, they achieve a complete functional closed loop of "local instant response and remote data management," adapting to the data transmission needs of electronic protective gear in various scenarios such as competition and training. 3. In this invention, by connecting the low-power control module with the data acquisition, processing, and communication modules, the power supply to the high-power modules can be cut off when not in operation, leaving only the wake-up detection unit. Upon triggering an impact, the entire module is instantly woken up, resulting in a rapid response. This avoids wasted power during inactivity and ensures that no impact signal is missed. The wake-up detection unit and link detection unit can provide real-time feedback on the protective gear's operating status, which is then transmitted to the terminal via the multi-mode transmission module. Personnel can remotely monitor the protective gear's operation, proactively troubleshoot faults, and reduce on-site maintenance frequency. 4. In this utility model, by connecting the power switching unit of the power supply module with a 220V external power supply and a lithium battery, it can instantly switch to the backup lithium battery when the power grid is interrupted, ensuring that the relay link is not interrupted; after the external power supply is restored, it automatically switches back and charges, avoiding the interruption of protective gear data transmission due to power supply problems, and further ensuring the continuity of transmission.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a wireless data transmission device for electronic protective gear, comprising a magnetic base, multiple sensors, a data acquisition module, a signal conditioning circuit, an ADC chip, a data processing and verification module, a node wireless communication module, a multi-mode transmission module, a power supply module, a low-power control module, and a Flash storage module. The magnetic base is fixedly installed on the inner side of the electronic protective gear. Multiple sensors are set at various scoring points of the protective gear to collect impact sensing information. The output terminals of the multiple sensors are electrically connected to the input terminal of the signal conditioning circuit, and the output terminal of the signal conditioning circuit is electrically connected to the input terminal of the ADC chip for noise reduction of the analog signal. The amplification and processing are performed as follows: the output of the ADC chip is electrically connected to the input of the data acquisition module to convert the processed analog signal into a digital signal; the output of the data acquisition module is electrically connected to the input of the data processing and verification module; the data processing and verification module includes a main control MCU, which receives digital signals and generates data frames with timestamps, and performs data verification through a built-in CRC32 and logic verification unit; the Flash storage module is electrically connected to the data processing and verification module for data buffering; and the node wireless communication module is electrically connected to the output of the data processing and verification module to wirelessly transmit the verified data stream to an external receiving terminal. Specifically, by fixing the magnetic base inside the meter box, the entire device is securely attached to a suitable position within the box, preventing external vibrations from affecting its operation. Multiple sensors accurately collect analog signals from each scoring point of the striking protective gear. These signals are then uniformly processed by a signal conditioning circuit for noise reduction and amplification, effectively filtering out motion interference signals and enhancing weak sensing signals to provide high-quality analog signals for subsequent conversion. An ADC chip converts the conditioned analog signals into digital signals, which are then transmitted to the data processing and verification module via the data acquisition module. The main control MCU generates timestamped data frames, and combined with CRC32 and logical verification for dual protection, ensuring data integrity and accuracy. The data is then cached in real-time using a Flash storage module. The processed data, in response to wireless transmission interruptions and to avoid data loss, is stably transmitted to an external receiving terminal via a node wireless communication module. This enables real-time wireless feedback of protective gear strike data, meeting the referee's real-time scoring requirements in competitive scenarios. Due to its short transmission distance and low power consumption, it is suitable for battery-powered protective gear applications. The coverage and reliability of the multi-mode transmission module, along with multi-mode switching, address signal blind spots in complex environments, ensuring stable data upload to the remote platform. The entire chain, through modular division of labor, guarantees high reliability from signal acquisition to transmission while adapting to the lightweight and high-response requirements of electronic protective gear, meeting the precise acquisition and efficient transmission requirements of scoring point strike data in Sanda (Chinese kickboxing).

[0026] Reference Figure 1 and Figure 2 The power supply module is electrically connected to multiple sensors, signal conditioning circuits, ADC chips, data acquisition modules, data processing and verification modules, node wireless communication modules, Flash storage modules, and low-power control modules, respectively, to provide stable voltage for the operation of each module. The low-power control module is electrically connected to the data acquisition module, data processing and verification module, and node wireless communication module, respectively, to control each module to enter sleep mode when not in operation. Specifically, the power supply module, through its electrical connection with each functional module, provides a stable and compatible operating voltage to the entire device. This ensures that the entire chain—from the sensor's real-time sensing of impact signals, the signal conditioning circuit's noise reduction and amplification of analog signals, to the ADC chip's analog-to-digital conversion, the data acquisition module's signal integration, the data processing and verification module's frame generation and verification, to the Flash storage module's data caching, and the node's wireless communication module's wireless transmission—operates efficiently under stable power support. This avoids signal acquisition distortion, data processing errors, or transmission interruptions caused by voltage fluctuations, laying the foundation for the device's reliable operation. The low-power control module, through its connection with the data acquisition module, data processing and verification module, and node wireless communication module, actively controls these modules to enter sleep mode when not in operation, such as when the protective gear is not in use or there is no impact action, significantly reducing standby power consumption. When the sensor detects an impact signal or needs to be periodically woken up, it can quickly trigger the module to resume working state. This dynamic power management is suitable for scenarios where electronic protective gear usually relies on battery power, extending the usage time after a single charge, without affecting the response speed when acquiring impact signals. It achieves a balance between low-power standby and high-sensitivity operation, improving the device's battery life and user experience.

[0027] Reference Figure 1 and Figure 2 The low-power control module includes a wake-up detection unit, which triggers the device to wake up and resume operation when the next sampling cycle or external power supply is interrupted. After sampling and transmission are completed, the control device enters a deep sleep mode, with only the wake-up detection unit remaining operational. The data acquisition module includes an isolation unit connected between the ADC chip and the data processing and verification module for electrical isolation protection. The main control MCU chip of the data processing and verification module is electrically connected to the isolation unit of the data acquisition module to receive digital signals transmitted through the isolation unit. The data processing and verification module includes an encryption unit for encrypting data frames using AES-128 before transmitting them to the multi-mode transmission module. Specifically, the wake-up detection unit enables the device to form a closed-loop management system of "sleep-wake-work". In non-working state, the device enters deep sleep mode under the action of the low-power control module, with only the wake-up detection unit running, minimizing battery power consumption. This is suitable for scenarios where electronic protective gear relies on portable power supplies. When the next sampling cycle is triggered or after a brief interruption of external power supply, the wake-up detection unit can quickly trigger the entire device to wake up, ensuring that no impact signal is missed. This extends the battery life after a single charge and ensures timely response when using protective gear. The isolation unit in the data acquisition module connects the ADC chip and the data processing and verification module, and the electromagnetic interference and voltage fluctuations of the front-end analog signal link are blocked through electrical isolation. The back-end digital circuitry and the main control MCU of the data processing and verification module are directly electrically connected to the isolation unit, enabling stable reception of the isolated digital signals and preventing data distortion or MCU damage caused by interference. This is particularly suitable for scenarios in Sanda (Chinese kickboxing) where multiple devices operate simultaneously and the electromagnetic environment is complex, improving the reliability of the device. The newly added encryption unit in the data processing and verification module encrypts the generated data frames using the AES-128 encryption algorithm before transmitting them to the multi-mode transmission module or node wireless communication module as needed. This effectively prevents the theft or tampering of striking data during wireless transmission, ensuring the privacy and integrity of protective gear scoring data. This meets the requirements for data fairness and security in competitive sports, preventing data leakage or tampering from affecting the determination of competition results.

[0028] Reference Figure 1 and Figure 2 The multi-mode transmission module includes a link detection unit, a 4G module, a PLC module, and a Bluetooth module. The 4G module takes priority in the transmission link, with the PLC module as a backup. The link detection unit monitors the 4G signal strength in real time. When the signal strength is ≥-90dBm, the 4G module uploads encrypted data frames to the power platform. When the signal strength is <-90dBm, it automatically switches to the PLC module for data transmission, using the power line to transmit the data to a nearby power acquisition terminal, which then forwards it to the platform. The Bluetooth module is only activated during on-site debugging and is used to read cached data and modify configuration parameters via a mobile app. The power supply module includes a power switching unit, an external power supply interface, and a lithium battery. The power supply module connects to the 220V power grid and charges the lithium battery. When the external power supply is interrupted, the power switching unit automatically switches to lithium battery power to ensure uninterrupted data acquisition and storage. When the external power supply is restored, the power switching unit automatically switches back to external power and charges the lithium battery. Specifically, the 4G module enables long-distance, wide-area transmission of protective gear data to the power platform. The PLC module utilizes the existing power line network of the power system to solve data transmission problems in areas with weak 4G signals, ensuring stable access to the power platform regardless of changes in the scenario. The Bluetooth module is used only for on-site debugging, without relying on the power platform or interrupting the main link. Staff can quickly check for data anomalies and modify parameters via a mobile app within the power facility, adapting to the power system's management needs for low maintenance costs and high convenience. Simultaneously, the protective gear has no physical connection to the 220V power grid, utilizing the power line channel only through wireless or relay equipment to eliminate safety hazards. The power supply module connects to the 220V power grid and is electrically connected to the lithium battery, supplying power to the entire device and charging the lithium battery, ensuring a backup power supply in case of power failure.

[0029] Working Principle: First, the device connects to the smart meter via an RS485 interface. The magnetic base is fixed inside the meter box. The power supply module is connected to the 220V power grid and completes lithium battery charging. During initialization, the device establishes a connection with the power management platform via a 4G module, negotiates encryption keys, and sets the sampling period and transmission link priority (4G module takes precedence, PLC module is backup). During normal operation, the data acquisition module starts according to the sampling period, sampling the voltage and current analog signals output by the meter through an ADC chip. After noise reduction and amplification by the signal conditioning circuit, the signals are converted into digital signals. The isolation unit provides electrical isolation protection. The MCU of the data processing and verification module receives the digital signals. After receiving the digital signals, the main control MCU generates a data frame containing a timestamp, device ID, and impact parameters. Data accuracy is ensured by CRC32 and logical verification, and then it is encrypted by AES-128 before being transmitted to the multi-mode transmission module to ensure data integrity. The encrypted data frame is also cached in the Flash storage module to prevent data loss due to transmission interruption. The link detection unit of the multi-mode transmission module monitors the 4G signal strength in real time. If the signal meets the requirement of ≥-90dBm, the encrypted data frame is uploaded to the power platform through the 4G module. If the 4G signal is weak, it automatically switches to the PLC module and transmits the data to the nearby power acquisition terminal via the power line, and then the terminal forwards it to the platform. The Bluetooth module is only activated during on-site debugging. It reads cached data or modifies configuration parameters through a mobile APP, and reads historical data from the Flash cache or modifies configuration parameters, without affecting the normal transmission process. After sampling and transmission are completed, the low-power control module puts the control device into deep sleep mode, retaining only the wake-up detection unit to extend battery life. When the sensor detects an impact, reaches the next sampling cycle, or the external power supply is interrupted, the wake-up unit triggers the device to wake up and resume operation. If the external power supply is interrupted, the power supply module automatically switches to lithium battery power to ensure uninterrupted data acquisition and storage. When the external power supply is restored, it automatically switches back to external power supply and charges the lithium battery. The protective gear itself relies entirely on the lithium battery for power, with no external high-voltage grid and complete physical isolation from the 220V high-voltage grid. It interacts only wirelessly with the relay device, avoiding the risk of electric shock, complying with athlete wearing regulations, and ensuring wearing safety. The power module prioritizes operation via a 220V external power supply. In the event of a sudden power outage, the power switching unit automatically switches to a lithium battery backup power supply to ensure uninterrupted relay links. After the external power supply is restored, it automatically switches back and charges the backup lithium battery. By combining automatic link switching, Flash buffer retransmission, and dual verification, it ensures that the data collected and uploaded to the power platform is "not lost or tampered with," with a packet loss rate controlled below 0.5%. Furthermore, by employing a 24-bit ADC chip and signal conditioning circuit, the sampling error is extremely small, far exceeding the error level of existing devices, meeting the requirements for high-precision power metering. Electrical isolation design enhances the device's anti-interference capability and power safety, preventing damage to the equipment from power grid impacts.
