DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the term “and / or” in this paper is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. In addition, the character “ / ” in this paper generally represents an “or” relationship between the front and rear associated objects without special explanation.

[0028] A vehicle intrusion theft prevention detection system, method, vehicle and medium provided by the present application will be described below in combination with the drawings in the specification.

[0029] Referring to Figure 1 and Figure 2 The vehicle intrusion theft prevention detection system comprises an ultrasonic sensor 100 and a signal processing module 120, and the ultrasonic sensor 100 is connected to the signal processing module 120.

[0030] The ultrasonic sensor 100 is arranged in the cabin of the vehicle, and the ultrasonic sensor 100 comprises a transmitting unit 101 and a receiving unit 102. The transmitting unit 101 periodically transmits ultrasonic waves to the entire cabin, and the receiving unit 102 receives echo signals formed based on ultrasonic wave reflection. The transmitting unit 101 and the receiving unit 102 are each at least one, and the ultrasonic wave beam emitted by the transmitting unit 101 can cover all areas in the cabin, such as Figure 3In some embodiments, in order to ensure that the ultrasonic wave beam covers the entire cabin control as much as possible, the number of the emission units 101 is determined according to the overall size of the vehicle, the space size, for example, a small two-door car can be configured with one emission unit 101, a three-door car can be configured with two emission units 101, an MPV can be configured with three emission units 101, and the like, which is not limited in particular. The ultrasonic sensor 100 can be arranged at any position in the cabin, preferably, all the emission units 101 and the receiving unit 102 are arranged at the position of the vehicle sunroof controller, or are integrated in the vehicle sunroof controller as shown. Figure 4 As shown, part of the multiple emission units 101 are arranged at the position of the vehicle C pillar, and the remaining emission units 101 are arranged at the position of the vehicle sunroof controller or are integrated in the vehicle sunroof controller. The receiving unit 102 is arranged at the position of the vehicle sunroof controller or is integrated in the vehicle sunroof controller. Figure 5 As shown, part of the multiple emission units 101 are arranged at the position of the vehicle C pillar, and the remaining emission units 101 are arranged at the position of the vehicle sunroof controller or are integrated in the vehicle sunroof controller. The receiving unit 102 is arranged at the position of the vehicle sunroof controller or is integrated in the vehicle sunroof controller.

[0031] When all the emission units 101 and the receiving unit 102 are arranged at the position of the vehicle sunroof controller or are integrated in the vehicle sunroof controller, at least one of all the emission units 101 is directed to the front seat range, so that the corresponding ultrasonic wave beam can cover the front seat; at least one of the remaining emission units 101 is directed to the rear seat, so that the corresponding ultrasonic wave beam can cover the rear seat and the trunk area.

[0032] When part of the emission units 101 are arranged at the position of the vehicle sunroof controller or are integrated in the vehicle sunroof controller, and the remaining part of the emission units 101 are arranged at the position of the vehicle C pillar, the emission units 101 arranged at the position of the vehicle C pillar can enhance the ultrasonic signal strength of the trunk area and improve the detection accuracy of the trunk area.

[0033] In addition, the ultrasonic sensor 100 starts to emit ultrasonic waves to the cabin only after the vehicle enters a security state, wherein the security state refers to that all doors, windows, trunk lids are locked, and the engine control system is locked.

[0034] The signal processing module 120 can determine the emission period adjustment information of the ultrasonic wave according to the echo signal and determine whether an illegal intrusion or theft behavior occurs according to the adjusted echo signal, wherein the adjusted echo signal is received after the ultrasonic sensor 100 emits ultrasonic waves according to the emission period adjustment information.

[0035] The signal processing module 120 determines whether the illegal intrusion or theft occurs according to whether the adjusted echo signal has the Doppler effect. If the adjusted echo signal has the Doppler effect, it indicates that the cabin may change from the original static stable state to dynamic state because the vehicle door, window or the like is damaged, thereby determining that the illegal intrusion or theft occurs. If the adjusted echo signal does not have the Doppler effect, it indicates that the echo signal in the current cabin is still in the static stable state, and the vehicle door, window or the like is not damaged, thereby determining that the illegal intrusion or theft does not occur. The static stable state refers to a state that no object in the cabin moves when the vehicle is in the state of being protected.

[0036] The Doppler effect of the adjusted echo signal refers to that an object in the detection range of the ultrasonic sensor 100 moves, the moving object causes the frequency of the reflected ultrasonic echo to change, and the change is reflected on the echo signal. Specifically, when the Doppler effect occurs, the echo signal is the superposition of the direct wave, reflected wave and Doppler wave, and the envelope of the echo signal will have wave peaks and wave troughs. When the Doppler effect does not occur, the echo signal is the superposition of the direct wave and reflected wave, and the envelope of the echo signal is a straight line.

[0037] In addition, when the ultrasonic sensor 100 starts to work, it emits ultrasonic waves at a longer time interval (i.e., ultrasonic emission period), thereby reducing power consumption. When it is determined according to the signal strength change of the echo signal that the ultrasonic emission time interval needs to be adjusted, the signal processing module 120 generates emission period adjustment information and sends it to the ultrasonic sensor 100. The ultrasonic sensor 100 emits ultrasonic waves according to the adjusted period in the emission period adjustment information, and then receives the adjusted echo signal. The signal processing module 120 determines whether the illegal intrusion or theft occurs according to whether the adjusted echo signal has the Doppler wave effect. The adjusted period is shorter than the period when the ultrasonic wave starts to work.

[0038] When the vehicle is in the non-protected state, the vehicle intrusion and theft detection system is in the sleep state, and it almost does not consume current.

[0039] The vehicle intrusion theft prevention detection system provided by the embodiments of the present application uses the echo signals collected by the ultrasonic sensor 100 to monitor illegal intrusion or theft, which can detect the entire cabin space, including the position of the user's feet inside the vehicle, the corner position of the windshield, the blind area of the seat back, etc. It does not need to increase the camera, and combines the high-accuracy algorithm with technical barriers. It only needs to determine whether illegal intrusion or theft occurs according to whether the Doppler wave effect occurs. The intrusion theft detection is simple and reliable, cost-effective, and will not involve privacy leakage. In addition, the ultrasonic sensor 100 starts to emit ultrasonic waves only when the vehicle enters the defense state, and adjusts the emission period of the ultrasonic waves in real time according to the received echo signals, thereby reducing power consumption.

[0040] Specifically, the signal processing module 120 can shorten the current period when the echo signal strength of the current period exceeds the signal strength threshold, to obtain an adjusted period, so that the ultrasonic sensor 100 emits ultrasonic waves and receives an adjusted echo signal at the adjusted period. The emission period adjustment information includes the adjusted period.

[0041] When the echo signal strength of the current period exceeds the signal strength threshold, it means that the static stable state inside the cabin is broken, and continuous echo signals need to be obtained to determine whether the Doppler effect occurs. At this time, the current ultrasonic emission period is shortened to obtain an adjusted period, and the ultrasonic sensor 100 emits ultrasonic waves and receives an adjusted echo signal according to the adjusted period. The ultrasonic emission time interval indicated by the current period is greater than the emission time interval indicated by the adjusted period, and the adjusted period is the reciprocal of the ultrasonic emission frequency f0kHz. The value of the ultrasonic emission frequency f0 is in the range of 20kHz to 1GHz.

[0042] It should be emphasized that the ultrasonic emission frequency does not change throughout the process, and the emission time interval is adjusted. For example, the current period is Ta, and the adjusted period is Tb. When the ultrasonic sensor 100 emits ultrasonic waves at the current period Ta, the Tb time in the current period Ta is actually emitted, and the remaining Ta-Tb time is not working, which can reduce power consumption. Based on this, the envelope displayed by the echo signal of the current period is discontinuous. When the adjusted period The envelope displayed by the adjusted echo signal is continuous, and whether the Doppler effect occurs is determined based on the continuous adjusted echo signal. When the cabin is in a static stable state, ultrasonic emission is performed at Ta, and when the static stable state changes to dynamic, ultrasonic emission is performed at Tb, thereby reducing the power consumption of the entire system.

[0043] Furthermore, if the echo signal strength in the current cycle does not exceed the signal strength threshold, the ultrasonic sensor 100 continues to emit ultrasonic waves in the current cycle. The signal strength threshold can be set empirically or obtained through test calibration. Preferably, it is obtained by measuring and calibrating various factors that affect the static stability of the cabin, such as the cabin space shape and interior condition. This signal strength threshold is the boundary value between the static stable state and the dynamic state. Different vehicles have different signal strength thresholds, thereby improving the accuracy of unauthorized intrusion detection.

[0044] In some embodiments of this application, the signal strength threshold includes a first signal strength threshold and a second signal strength threshold, wherein the first signal strength threshold is less than the second signal strength threshold. The signal processing module 120 includes a period adjustment unit and an intrusion determination unit.

[0045] The period adjustment unit is used to adjust the current period from the first period to the second period when the echo signal intensity of the current period exceeds the first signal intensity threshold but does not exceed the second signal intensity threshold, so that the ultrasonic sensor 100 switches from the first mode to the second mode; and to adjust the current period from the second period to the third period when the echo signal intensity of the current period exceeds the second signal intensity threshold, so that the ultrasonic sensor 100 switches from the second mode to the third mode.

[0046] The first mode, the second mode, and the third mode refer to the ultrasonic sensor 100 emitting ultrasonic waves and receiving corresponding echo signals at periods T1, T2, and T3, respectively. Figure 6 As shown, the first period T1, the second period T2, and the third period T3 shorten sequentially, with the third period T3 being the reciprocal of the ultrasonic emission frequency f0. During the first period T1, the actual working time of the ultrasonic sensor 100 is T3; during the remaining T1-T3 period, the ultrasonic sensor 100 is not working. Similarly, during the second period T2, the actual working time of the ultrasonic sensor 100 is T3; during the remaining T2-T3 period, the ultrasonic sensor 100 is not working. It is important to emphasize that the emission frequency of the ultrasonic sensor 100 is f0 in all three modes.

[0047] That is, the ultrasonic wave transmission time interval indicated by the first period is the longest, the ultrasonic wave transmission time interval indicated by the second period is the second longest, and the ultrasonic wave transmission time interval indicated by the third period is the shortest. When the ultrasonic sensor 100 transmits ultrasonic waves in the first period, the time proportion of the actual operation of the ultrasonic sensor 100 in the first period is small, the current is reduced, the power consumption is the smallest, and the first mode can also be called a low-power-consumption mode. In the low-power-consumption mode, the vehicle intrusion alarm detection system can maintain detection for a very long time, and in the case that the vehicle needs to be in a guarded state for a long time, the vehicle intrusion alarm detection system can always stably and continuously detect.

[0048] When the ultrasonic sensor 100 transmits ultrasonic waves in the second period, compared with the first period, the time proportion of the actual operation of the ultrasonic sensor 100 in the second period is large, and the intermittent time of the corresponding echo signal is also shorter. By shortening the first period to the second period, a more compact echo signal is obtained, so as to further determine whether the signal strength of the echo signal corresponding to the second period exceeds the second signal strength threshold. If it exceeds, it is determined that illegal intrusion or theft behavior is likely to occur, and the second period needs to be shortened to the third period. Whether the Doppler effect occurs is determined according to the echo signal corresponding to the third period. If the signal strength of the echo signal corresponding to the second period suddenly becomes less than or equal to the first signal strength threshold, it is determined that the previous illegal intrusion or theft behavior is a false positive. Therefore, the second mode can also be a confirmation mode. By setting the second mode, the probability of false positive of illegal intrusion or theft behavior is reduced, and the detection accuracy is improved.

[0049] When the ultrasonic sensor 100 transmits ultrasonic waves in the third period, the corresponding echo signal is continuous, and whether the Doppler effect occurs can be analyzed according to the complete echo signal to determine whether illegal intrusion or theft behavior occurs.

[0050] The intrusion determination unit is used to determine illegal intrusion or theft behavior when the adjusted echo signal has the Doppler effect. The adjusted echo signal is formed based on the ultrasonic wave transmitted in the third period. That is, the judgment of illegal intrusion or theft behavior is performed on the echo signal formed by the ultrasonic wave transmitted in the third period. Not only can the power consumption be reduced, but also the false positive rate can be reduced, and the detection accuracy can be improved. Moreover, it only needs to analyze the Doppler effect of the echo signal formed by the ultrasonic wave transmitted in the third period, without the need for complex and high-cost algorithms for analysis, so the cost is lower and more cost-effective.

[0051] In addition, the period adjustment unit determines, according to the echo signal intensity of each current period, whether the next period continues to perform ultrasonic wave emission according to the current period information or needs to shorten or lengthen the current period to form the next period information. Specifically, if the echo signal intensity of the current period does not exceed the first signal intensity threshold, the ultrasonic sensor 100 continues to perform ultrasonic wave emission in the first period, that is, remains in the first mode.

[0052] After the ultrasonic sensor 100 switches from the first mode to the second mode, if the echo signal of the new current period has no change compared with the echo signal of the last period, and remains in the state that the echo signal intensity exceeds the first signal intensity threshold but does not exceed the second signal intensity threshold, the ultrasonic sensor 100 remains in the second mode. If the ultrasonic sensor 100 has been in the second mode, but the received echo signal intensity changes from exceeding the first signal intensity threshold but not exceeding the second signal intensity threshold to not exceeding the first signal intensity threshold and has not exceeded the first signal intensity threshold for a preset time, the period adjustment unit adjusts the current period from the second period to the first period, so that the ultrasonic sensor 100 switches from the second mode back to the first mode. In this case, it may be due to the interference in the echo signal, causing the signal intensity to change from exceeding the first signal intensity threshold to not exceeding the first signal intensity threshold.

[0053] After the ultrasonic sensor 100 switches from the second mode to the third mode, if the echo signal of the new current period has no change compared with the echo signal of the last period, the ultrasonic sensor 100 remains in the third mode. If the intrusion determination unit determines that the echo signal in the third mode has no Doppler effect, it is determined that no illegal intrusion or theft occurs, and the period adjustment unit adjusts the third period to the first period, so that the ultrasonic sensor 100 switches from the third mode to the first mode. More specifically, the intrusion determination unit determines whether there is a continuous wave peak and trough envelope information for a period in the third mode. If there is, it is determined that illegal intrusion or theft occurs, and then an alarm is given. After the alarm is over, the current illegal intrusion or theft monitoring is over, and the ultrasonic sensor returns to the first mode for the next illegal intrusion or theft monitoring. If there is not (that is, the envelope fluctuation is not significant and tends to be a smooth straight line), no alarm event is given, and the ultrasonic sensor switches from the third mode to the first mode.

[0054] The period adjustment unit adjusts the current period from the first period to the second period when it is detected that the echo signal intensity of the current period exceeds the first signal intensity threshold but does not exceed the second signal intensity threshold. Similarly, the period adjustment unit adjusts the current period from the second period to the third period when it is detected that the echo signal intensity of the current period exceeds the second signal intensity threshold.

[0055] In some embodiments of the present application, the signal processing module 120 further comprises a detection sensitivity adjustment unit for adjusting the detection sensitivity of the ultrasonic sensor according to the closed state of the cabin, wherein the detection sensitivity is determined according to the emission period of the ultrasonic sensor, the continuous emission time of the ultrasonic wave in a single emission period, the emission power of the ultrasonic wave, the preset echo signal strength threshold, and the signal gain during signal amplification. The closed state of the cabin includes the state of the vehicle window, the state of the sunroof, the state of the vehicle door, and the state of the trunk.

[0056] Adjusting the detection sensitivity is actually adjusting the emission period, the continuous emission time of the ultrasonic wave in a single emission period, the emission power, the echo signal strength threshold, and the signal gain. Adjusting the detection sensitivity according to the closed state of the cabin can reduce the false alarm rate of the intrusion and theft detection. Illustratively, when the cabin is in a completely closed state, the other dynamic targets detected in the cabin are most likely to be illegal intrusion or theft behavior. However, if it is in a semi-closed state (such as the vehicle window being opened), it may be a pedestrian passing by the vehicle window. If the detection sensitivity in the fully closed state is still used at this time, it will be misjudged as illegal intrusion or theft behavior. Therefore, when the cabin is in a completely closed state, the detection sensitivity is the highest, and the worse the cabin closure, the lower the corresponding detection sensitivity. Illustratively, the detection sensitivity can be a specific percentage, and the value range can be 50%-100%, wherein the detection sensitivity is 50% when the vehicle window, sunroof, vehicle door, and trunk are in a fully open state, and the detection sensitivity is 100% when the cabin is completely closed. In other embodiments, the detection sensitivity can be divided into multiple levels such as first level, second level, third level, etc., wherein the first level represents the highest detection sensitivity, and the second level, third level, etc. are sequentially reduced, and different levels are applied to different closed states.

[0057] The detection sensitivity adjustment unit automatically adjusts the detection sensitivity according to the detected closed state of the cabin, such as the percentage of adjustment, the level of adjustment, etc. Illustratively, when the vehicle enters the armed state, if it is determined that the cabin is completely closed and the original detection sensitivity is low, the detection sensitivity adjustment unit adjusts the original detection sensitivity to the highest, and if the original detection sensitivity is already the highest, the ultrasonic sensor is detected using the original detection sensitivity.

[0058] In addition, when the detection sensitivity in the form of percentage is adjusted, different adjustment amplitudes correspond to different parameter changes. For example, when the detection sensitivity is adjusted from 100% to 50%, the corresponding parameter changes include that the emission period is extended, the continuous emission time of the ultrasonic wave is reduced, the power is reduced, the signal strength threshold is increased, the signal gain of the amplifier 190 is reduced, and the like. The specific parameter changes corresponding to different adjustment amplitudes are obtained by testing and calibrating the actual vehicle under different closed states of the cabin, and are not specifically limited herein. Similarly, if the detection sensitivity in the form of level is adjusted, the specific values of the detection parameters corresponding to different levels are different. For example, when the detection sensitivity is level one, the emission period is shorter than that when the detection sensitivity is level two. The specific values of the detection parameters corresponding to different levels can also be obtained by testing and calibrating the actual vehicle, and are not limited herein.

[0059] In addition, the profiles, space volumes, interior trim parts, and seat surface materials of different vehicle cabin spaces are different, which also affect the detection parameters corresponding to the detection sensitivity. The specific detection parameters corresponding to the detection sensitivity can be obtained by testing and calibrating the actual vehicle to obtain the most ideal parameter configuration for the corresponding vehicle model.

[0060] After obtaining the adjusted detection sensitivity, the vehicle intrusion alarm detection system detects according to the parameters in the adjusted detection sensitivity.

[0061] The vehicle intrusion alarm detection system provided by the embodiments of the present application can adjust the detection sensitivity according to the closed state of the cabin, thereby avoiding false alarms to the greatest extent and further improving the accuracy of intrusion alarm detection.

[0062] In some embodiments of the present application, the system further includes an inclination sensor 130 and an acceleration sensor 140. The inclination sensor 130 can detect the inclination value of the vehicle, and the acceleration sensor 140 can detect the acceleration of the vehicle.

[0063] The signal processing module 120 compares the inclination value with the inclination threshold value and the acceleration with the acceleration threshold value, and determines that it is an illegal towing or tire theft when the inclination value exceeds the inclination threshold value and / or the acceleration exceeds the acceleration threshold value. The inclination threshold value and the acceleration threshold value can be preset values determined according to experience, testing, and actual vehicle calibration, or can be actually determined according to the current scene of the vehicle.

[0064] Preferably, the inclination threshold value and the acceleration threshold value are determined by a background scan of the vehicle when the vehicle is in an armed state. The background scan is performed each time the vehicle enters the armed state, and the signal processing module collects the inclination value and the acceleration value of the vehicle at a preset scan frequency (such as 2 Hz). After filtering, the inclination value + a is taken as the inclination threshold value, and the acceleration value + b is taken as the acceleration threshold value, where a and b are empirical values or are obtained after real vehicle calibration tests.

[0065] The frequency of data scanning in the background scan mode is low, which can minimize the power consumption of the vehicle intrusion and theft detection system. When the inclination value exceeds the inclination threshold value and / or the acceleration exceeds the acceleration threshold value, the system switches from the background scan mode to a high-speed mode, in which the data acquisition frequency is greater than or equal to a high-speed frequency threshold (such as 8 Hz). In the high-speed mode, if the data continuously exceeds the threshold value for a period of time, it is determined that illegal towing or tire theft has occurred. The high-speed mode improves the data acquisition frequency, thereby improving the accuracy and real-time performance of the inclination and acceleration acquisition and reducing false positives.

[0066] In addition, each time the vehicle enters the armed state, a new inclination threshold value and a new acceleration threshold value are obtained through the background scan, and real-time illegal towing or tire theft is determined based on the new inclination threshold value and the new acceleration threshold value. Compared with the preset values, real-time updating of the inclination threshold value and the acceleration threshold value makes the detection result more accurate. For example, if the vehicle is parked in a flat area without a road surface, the inclination threshold value in this scenario is small, and if the vehicle is parked on a slope, the inclination threshold value in this scenario is large.

[0067] More specifically, whether tire theft occurs is determined based on the comparison result between the inclination value and the inclination threshold value, and whether illegal towing occurs is determined based on the comparison result between the inclination value and the inclination threshold value and the comparison result between the acceleration and the acceleration threshold value.

[0068] The vehicle intrusion and theft detection system provided by the embodiments of the present application detects illegal intrusion or theft behavior through the ultrasonic sensor 100, detects illegal towing and tire theft behavior through the inclination sensor 130 and the acceleration sensor 140, so that the vehicle intrusion and theft detection system can cover various scenarios such as window breaking theft, trunk damage, tire theft, illegal towing, and impact, thereby increasing the diversity of detection types. In addition, real-time updating of the inclination threshold value and the acceleration threshold value improves the detection accuracy of illegal towing and tire theft behavior.

[0069] In some embodiments of the present application, the system further includes an alarm 150 and a domain controller 160.

[0070] The signal processing module 120 generates an alarm signal in the case of determining that an illegal intrusion or theft behavior, illegal towing and / or tire theft behavior occurs.

[0071] The alarm 150 gives a warning to the illegal actor according to the alarm signal.

[0072] The domain controller 160 synchronizes the alarm signal to the user terminal associated with the vehicle.

[0073] Specifically, the alarm 150 can be a backup battery alarm which will emit an alarm sound to deter the illegal actor after receiving the alarm signal sent by the signal processing module 120. At the same time, the signal processing module 120 will also send the alarm signal to the domain controller 160, and the domain controller 160 will upload the alarm signal to the cloud server and synchronize it to the user terminal (such as mobile phone, bracelet, etc. electronic device) associated with the vehicle through the cloud server, so as to inform the user that illegal intrusion / theft or illegal towing behavior has occurred, so that the user can take timely measures. Among them, the user can be informed through a remote call or a short message.

[0074] In addition, the alarm signal can be different according to the type of illegal behavior, such as the alarm sound corresponding to the illegal intrusion or theft behavior is different from the illegal towing and / or tire theft behavior.

[0075] Further, the system further comprises a communication module 170, which is in communication connection with the domain controller and the signal processing module 120 respectively, and the communication module 170 comprises a CAN (Controller Area Network) communication submodule 171 or a LIN (Local Interconnect Network) communication submodule 172.

[0076] In the embodiment, in addition to being in communication connection with the domain controller and the signal processing module 120, the communication module 170 can also be in communication connection with each functional module in the vehicle. For example, the ultrasonic sensor needs to start running only after receiving the signal that the vehicle enters the armed state, and the vehicle intrusion alarm detection system needs to obtain the signal of entering the armed state through the communication module 170. For another example, when adjusting the detection parameters of the ultrasonic sensor, the vehicle intrusion alarm detection system needs to obtain the signals of the vehicle speed, engine state, door state, window state, sunroof state, trunk state, etc. through the communication module 170. In addition, the communication module 170 can be in LIN communication mode, or in CAN communication mode, or in other communication protocols that can be applied in vehicles, and can be flexibly selected from different communication modes according to actual needs.

[0077] In some embodiments of the present application, the vehicle intrusion burglar alarm system further comprises a driver 180, an amplifier 190 and a demodulator 200.

[0078] The driver 180 is connected to the signal processing module 120 at one end and to the transmitting unit 101 in the ultrasonic sensor at the other end. The amplifier 190 is connected to the receiving unit 102 at one end and to the demodulator 200 at the other end, and the demodulator 200 is also connected to the signal processing module 120.

The amplifier 190 amplifies the echo signal collected by the receiving unit 102, sends the amplified echo signal to the demodulator 200, and the demodulator 200 demodulates the amplified echo signal to finally extract the signal envelope as an analog signal and input it into the signal processing module 120 for subsequent analysis of the echo signal by the signal processing module 120.
