[0021] Regarding the foregoing and other technical contents, features and effects of the present utility model, they will be clearly presented in the following detailed description of the embodiments in conjunction with the attached Figure 1 to Figure 3 In the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all referenced to the accompanying drawings of the specification.

[0022] The exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0023] As Figure 1 shown, a wearable monitoring terminal warning system includes a sensor module, a data analysis module and a remote warning module. Among them, the sensor module includes a variety of biosensors, such as a heart rate sensor, a blood pressure sensor, a body temperature sensor, etc., for collecting the physiological data of users in real time.

[0024] The data analysis module is used to receive the physiological data collected by the sensor module and perform anomaly analysis, and generate a corresponding warning instruction signal based on the anomaly detection result; in the specific implementation process, the data analysis module includes:

[0025] An analog front end (AFE), which is used to process the analog signals from the biosensors. A signal conditioning circuit is provided inside it to perform preliminary processing on the analog signals output by the biosensors, including amplification, filtering, linearization, etc., to improve the quality and usability of the signals. It also includes an analog-to-digital converter (ADC) to convert the conditioned analog signals into digital signals for subsequent processing.

[0026] A microcontroller is used to analyze the output data of the analog front end to detect abnormal situations. This part can be implemented by mature data processing technologies. For example, abnormal situations can be identified according to preset thresholds or learning models, and a warning instruction signal can be generated.

[0027] To ensure the effective transmission of the warning instruction signal, a remote warning module is used to perform remote transmission processing on the warning instruction signal, including:

[0028] An instruction isolation and amplification circuit is used to perform pre-isolation and amplification on the warning instruction signal;

[0029] A filtering and noise reduction circuit is used to filter out the electromagnetic noise components in the amplified signal; and

[0030] A precision power amplifier and transmitting circuit is used to further notch filter the output signal of the filtering and noise reduction circuit, and make the signal meet the transmission requirements through power amplification and frequency selection adjustment. Finally, the warning instruction is remotely transmitted to the warning terminal through the transmitting antenna E1.

[0031] Specifically, in the above, as Figure 2 shown, the instruction isolation and amplification circuit includes a voltage follower AR1. The non-inverting input terminal of the voltage follower AR1 is connected to the warning instruction signal output terminal of the data analysis module, and the inverting input terminal of the voltage follower AR1 is connected to the input terminal of the filtering and noise reduction circuit through its output terminal. Among them, the voltage follower AR1 has an isolation effect on the issuance of the warning instruction signal, preventing the influence of subsequent circuits on the signal source, ensuring the integrity of the signal, and effectively enhancing the anti-interference ability of the system.

[0032] To eliminate the influence of electromagnetic noise in the environment on the warning instruction, a filtering and noise reduction circuit is used to further process the signal. As Figure 2 shown, the filtering and noise reduction circuit includes an operational amplifier AR2. The non-inverting input terminal of the operational amplifier AR2 is connected to one end and the adjustment terminal of a potentiometer RP1, and is grounded through a capacitor C2. The other end of the potentiometer RP1 is connected to one end of a resistor R1, a capacitor C1, and the output terminal of the voltage follower AR1. The other end of the resistor R1 is grounded, and the other end of the capacitor C1 is connected to the inverting input terminal and the output terminal of the operational amplifier AR2. The output terminal of the operational amplifier AR2 is connected to the input terminal of the precision power amplifier and transmitting circuit through a capacitor C3.

[0033] During the operation of the filtering and noise reduction circuit, the resistor R1, potentiometer RP1, and capacitors C1 and C2 form a second-order RC filtering structure. Under the drive of the operational amplifier AR2, frequency selection filtering is performed to effectively filter out the electromagnetic interference frequencies in the signal and improve the signal-to-noise ratio of the signal. At the same time, in order to improve the frequency selection filtering performance of the system and adapt to different electromagnetic signal environment characteristics and application requirements, the cut-off frequency of the filter can be changed by adjusting the resistance value of RP1 to better match the signal characteristics and system requirements.

[0034] The signal after frequency selection filtering is coupled through the capacitor C3 and then sent into the precise power amplifier transmitting circuit for pre-transmission processing, such as Figure 3 As shown, the precise power amplifier transmitting circuit includes a notch unit and a power amplifier unit. The notch unit includes an operational amplifier AR3. The inverting input terminal of the operational amplifier AR3 is connected to one end of capacitors C4 and C5. The other end of capacitor C4 is connected to the output terminal of the filtering and noise reduction circuit through resistor R2 and is connected to the other end of capacitor C5 and one end of resistor R3 through inductor L1. The other end of resistor R3 is connected to the output terminal of the operational amplifier AR3. The non-inverting input terminal of the operational amplifier AR3 is connected to the adjustment terminal of potentiometer RP2. One end of potentiometer RP2 is connected to the +12V power supply, and the other end of potentiometer RP2 is grounded through resistor R4; the output terminal of the operational amplifier AR3 is connected to the transmitting antenna E1 through the power amplifier unit.

[0035] Furthermore, the power amplifier unit includes a triode VT1. The base of the triode VT1 is connected to the output terminal of the operational amplifier AR3. The collector of the triode VT1 is connected to the gate of the MOS transistor Q1. The emitter of the triode VT1 and the drain of the MOS transistor Q1 are connected to the transmitting antenna E1 and are connected to the +12V power supply through a parallel combination of capacitor C6 and inductor L2. The source of the MOS transistor Q1 is grounded.

[0036] During the operation of the precise power amplifier transmitting circuit, since wearable devices are often in a power frequency environment and are easily affected by power frequency interference, a notch unit is used to filter out power frequency noise. The specific working principle is as follows: In the notch unit, capacitors C4, C5, inductor L1, and capacitor C3 form a notch network at the negative feedback terminal of the operational amplifier AR3. The resonance generated by the RLC notch is used to suppress power frequency noise to improve the signal transmission quality and system reliability.

[0037] The power amplifier unit amplifies the useful signal processed by the notch unit. Among them, the triode VT1 and the MOS transistor Q1 form a combined power amplifier transistor to provide efficient power amplification and good linear characteristics, providing a signal with sufficient power for the transmitting antenna E1 to ensure the effective transmission of wireless signals. At the same time, inductor L2 and capacitor C6 play a role in resonance frequency selection during the power amplification process, thereby selecting the required frequency components, enhancing the transmission effect of the target signal, and improving the reliability and quality of signal transmission.

[0038] In summary, the wearable monitoring terminal warning system of the present application collects users' physiological data in real time by integrating multiple biosensors, uses an analog front end and a microcontroller for signal conditioning and anomaly analysis, and generates a warning instruction signal. The remote warning module further isolates, amplifies, filters, and reduces noise of the signal, and uses a notch unit and a combined power amplifier tube for precise power amplification. Finally, the signal is transmitted to the warning terminal through a transmitting antenna, ensuring that the transmission quality of the warning instruction signal and the system reliability are significantly improved in an environment with electromagnetic noise and power frequency interference, thereby realizing efficient and accurate health monitoring and warning services.

[0039] The above is a further detailed description of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to this; for those skilled in the art of the present invention and related technical fields, based on the technical solution idea of the present invention, the expansions, operation methods, and data replacements made should all fall within the protection scope of the present invention.
