[0031] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

[0033] Figure 1 This is a schematic diagram of the structure of the reversing buzzer fatigue monitoring device proposed in the embodiment of the utility model. Figure 1 As shown, the reversing buzzer fatigue monitoring device 00 includes: a collection unit 100, a processing unit 200 and an alarm unit 300;

[0034] The acquisition unit 100 is located on the buzzer part of the reversing buzzer and includes a sound sensor 101, a vibration sensor 102 and a temperature sensor 103;

[0035] The processing unit 200 includes a sound intensity receiving port 1, a vibration frequency receiving port 2, and a temperature receiving port 3. The sound intensity receiving port 1 is connected to the sound sensor 101 via a first detection line, the vibration frequency receiving port 2 is connected to the vibration sensor 102 via a second detection line, and the temperature receiving port 3 is connected to the temperature sensor 103 via a third detection line.

[0036] The processing unit 200 further includes an alarm connection port 4 , which is electrically connected to the alarm unit 300 .

[0037] It should be noted that the reversing buzzer is generally connected to the vehicle main control, and the vehicle main control is pre-configured with the logic for controlling the reversing buzzer. For example, when the vehicle radar detects that the vehicle is reversing and the distance between the vehicles exceeds the threshold, the vehicle main control can control the reversing buzzer to sound to alert the driver so that the driver can respond accordingly. However, as the reversing buzzer is used for a long time, the environment changes, etc., the reversing buzzer will become fatigued or even fail. If it is not discovered in time, serious consequences may occur. In related technologies, most of them use fixed time points for inspection or fixed-point replacement. But before the problem is discovered during the inspection, the vehicle may encounter an unexpected situation due to the failure of the reversing buzzer.

[0038] Furthermore, the present invention provides a data acquisition unit 100 at the buzzer portion of the reversing buzzer (for example, the data acquisition unit 100 is provided at the speaker). Thus, the sound sensor 101 can measure the sound intensity of the reversing buzzer, the vibration sensor 102 can measure the vibration frequency of the reversing buzzer, and the temperature sensor 103 can measure the ambient temperature of the reversing buzzer, thereby enabling real-time data acquisition of the reversing buzzer's operating status. Furthermore, the reversing buzzer's operating status can be predicted over time and as the environment changes.

[0039] It is understood that the sound intensity range and vibration frequency range can be configured in advance in the processing unit 200. After the collected sound intensity, vibration frequency, and temperature are converted into electrical signals, the current working status of the reversing buzzer is determined and recorded by comparing the reference signal with the detection signal according to the integrated circuit in the processing unit 200 (such as a comparator). For example, the comparator in the processing unit 200 can include a sound intensity comparator and a vibration frequency comparator. The sound intensity comparator includes a detection terminal, a reference terminal, and an output terminal. The detection terminal is connected to the output terminal of the sound intensity sensor, and the output terminal is connected to the alarm unit 300. When the detection signal of the sound sensor 101 is greater than the reference value, the reversing buzzer is in a poor working state, and the alarm unit 300 is controlled to sound an alarm. Similarly, the vibration frequency comparator includes a detection terminal, a reference terminal, and an output terminal. The detection terminal is connected to the output terminal of the vibration sensor 102, and the output terminal is connected to the alarm unit 300. When the detection signal of the vibration sensor 102 is greater than the reference value, the reversing buzzer is in a poor working state, and the alarm unit 300 is controlled to sound an alarm. In another embodiment, a sound intensity comparator and a vibration frequency comparator may be further included. While the aforementioned embodiment sets a high reference value, the comparator in this embodiment sets a low reference value. Specifically, when the detection signal from the sound sensor 101 is less than the low reference value and greater than the high reference value, the reversing buzzer is operating poorly, and the alarm unit 300 is controlled to sound an alarm. And / or, when the detection signal from the vibration sensor 102 is less than the low reference value and greater than the high reference value, the reversing buzzer is operating poorly, and the alarm unit 300 is controlled to sound an alarm. For example, the device 00 may also include a counter to count the number of alarms, and a timer to record the duration of each alarm. As the reversing buzzer becomes increasingly poorly operating, the counter records more alarms, and the time intervals recorded by the timer become shorter, indicating that the reversing buzzer is becoming increasingly fatigued.

[0040] Furthermore, the processing unit 200 may be provided with a memory that records and stores the temperature, vibration frequency, and sound intensity of each alarm, i.e., when the reverse buzzer is not operating properly. The processing unit 200 analyzes this data to determine the changing trend of the reverse buzzer's alarm condition over time (e.g., the sound attenuation rate, vibration frequency, etc.). This allows the processing unit 200 to predict the reverse buzzer's operating condition based on this changing trend. In other words, the processing unit 200 can analyze the potential fatigue point or precursor to failure of the buzzer based on historical and current data.

[0041] For example, when the time between two alarms approaches a set time interval threshold and / or the total number of alarms approaches a set number of alarms threshold, the reversing buzzer is considered to be in a fatigue state. In other embodiments, a model training algorithm can also be used to train based on historical data to develop a model of the changing trends of the reversing buzzer's alarm conditions over time and ambient temperature. Based on the current data and the trained model, the driver and maintenance personnel can be given an early warning so that they can repair or replace the reversing buzzer.

[0042] It should be noted that the processing unit 200 can be an Arduino or STM32 series microcontroller with an ADC (digital-to-analog converter) and sufficient I / O interfaces. The acquisition frequency of each sensor in the acquisition unit 100 can be configured in advance to ensure data accuracy and real-time performance. The alarm unit 300 can provide visual information alarms, / or voice alarms, / or light and sound alarms, and other reminder methods.

[0043] Optionally, Figure 2 This is a schematic diagram of the structure of another reversing buzzer fatigue monitoring device proposed in the embodiment of the utility model. Figure 2 As shown, the reversing buzzer fatigue monitoring device 00 further includes a display unit 400. The processing unit 200 also includes a display port 5, and the display unit 400 is electrically connected to the display port 5. The display port 5 can be an HDMI interface or a VGA interface. The display unit 400 is an LED display, an OLED display, a micro-LED display, or an electronic paper display.

[0044] It is understandable that the display unit 400 can display the sound intensity data collected by the sound sensor 101, the vibration frequency data collected by the vibration sensor 102, the temperature data collected by the temperature sensor 103, and the alarm warning image (such as a red lightning image) and / or the alarm time of the alarm unit 300. The display unit 400 can be integrated into the vehicle display to display to the driver. The display unit 400 can also be integrated into the remote terminal to display to the background maintenance personnel, etc. In this way, when the data is abnormal, it is convenient for the staff to obtain information intuitively and perform maintenance in advance, and it is convenient for the driver to obtain information intuitively, predict in advance, and ensure driving safety.

[0045] The alarm unit 300 can automatically send an alarm notification, send an email, send a text message, or display a warning message directly on the monitoring interface. The monitoring interface can intuitively display data changes and alarm status in the form of charts to facilitate quick problem identification.

[0046] Optionally, Figure 3 This is a schematic diagram of the structure of another reversing buzzer fatigue monitoring device proposed in the embodiment of the present utility model. Figure 3 As shown, the reversing buzzer fatigue monitoring device 00 further includes: a communication module 500, the communication module 500 includes a first communication unit 501 and a second communication unit 502, and the first communication unit 501 and the second communication unit 502 are communicatively connected;

[0047] The first communication unit 501 is located in the communication terminal, and the second communication unit 502 is located in the processing unit.

[0048] The communication terminal is a mobile phone, tablet computer or desktop computer. That is, the fatigue monitoring device 00 can communicate with an external mobile phone, tablet computer or desktop computer, so that the driver or maintenance personnel can check the working status of the reversing buzzer anytime and anywhere.

[0049] In one embodiment, the communication module 500 includes a wireless communication module, which is one of a Wi-Fi module, a Bluetooth module, and a radio frequency module.

[0050] The wifi module can be an ESP8266 (Wi-Fi) model, and the bluetooth module can be an HC-05 / HC-06 (Bluetooth) model. This greatly facilitates the driver or maintenance personnel to monitor and analyze the working status of the reversing buzzer in real time.

[0051] In other embodiments, the monitoring data of the reversing buzzer obtained by the processing unit 200 may also be uploaded to a cloud server, a remote server, or the like.

[0052] Optionally, Figure 4 This is a structural diagram of another reversing buzzer fatigue monitoring device proposed in the embodiment of the utility model. Figure 4 As shown, the reversing buzzer fatigue monitoring device 00 also includes: a power module 600; the power module 600 includes multiple power supply interfaces, and the multiple power supply interfaces are respectively connected to the acquisition unit 100, the processing unit 200, the alarm unit 300 and the display unit 400.

[0053] The power module 600 supplies power to each unit to ensure its normal operation. In one embodiment, the power module 600 may also be configured with a fuse module and a power management module. The power management module can be connected to the vehicle's main control unit. When the vehicle's main control unit issues a power-on command, the power module 600 can then supply power to each unit. The configuration of the fuse module enhances the safety of the entire circuit. When the circuit experiences overcurrent and / or overvoltage, the fuse module can disconnect the power supply from the power module 600 to each unit.

[0054] Optionally, Figure 5 This is a structural diagram of another reversing buzzer fatigue monitoring device proposed in the embodiment of the utility model. Figure 5 As shown, the reversing buzzer fatigue monitoring device 00 further includes: a charging module 700, the power module 600 includes a charging interface, the charging module 700 includes a discharge interface, and the discharge interface is connected to the charging interface;

[0055] The charging module 700 also includes an external charging power supply 701, a charging control unit 702 and a charging switch 703. One end of the charging switch 703 is connected to the discharge interface, and the other end is connected to the external charging power supply 701. The control end of the charging switch 703 is connected to the charging control unit 702.

[0056] It is understood that a specially designed cable and interface are used to connect the charging port of the power module 600 to the discharge port of the charging module 700. This connection method not only ensures efficient power transmission, but also provides a certain degree of vibration and interference resistance through its physical connection structure, which can adapt to the slight shaking or electromagnetic interference that the monitoring device may encounter in different working environments.

[0057] The charging control unit 702 controls the charging switch 703, which controls when the external charging power supply 701 charges the power module 600. The charging switch 703 can be an electromagnetic relay. This charging switch 703 can adopt a circuit protection design to prevent overload and short circuit, effectively preventing safety accidents caused by abnormal external power supply.

[0058] Thus, when the power level of the power module 600 falls below a preset threshold, the charging control unit 702 initiates the charging process. Throughout the charging process, the charging control unit 702 uses high-precision current sensors and voltage sensors to continuously monitor the charging current and voltage in real time. Once it detects that the charging current exceeds the preset safety upper limit or that the voltage fluctuates abnormally, the charging control unit 702 immediately triggers a protection mechanism and sends a shutdown signal to the control end of the charging switch 703, causing the charging switch 703 to quickly disconnect and stop the charging process, thereby protecting the power module 600 and the entire monitoring device from damage. Furthermore, by configuring the power module 600 as a rechargeable power source, the utilization rate of the power module 600 is increased.

[0059] Furthermore, the reversing buzzer fatigue monitoring device proposed in the embodiment of the present invention uses a microprocessor and related sensors to collect parameters such as sound intensity, vibration frequency, and temperature during the operation of the reversing buzzer in real time. Through a communication module, the collected data is transmitted to the terminal or server to be monitored. The microprocessor, terminal, or server processes and analyzes the data, displaying the reversing buzzer's operating status in real time. When abnormal data is detected, an alarm unit sounds an alarm, prompting the operator to conduct an inspection. This can improve the accuracy and efficiency of reversing buzzer performance testing, ensuring its reliability and safety in long-term use.

[0060] Moreover, in the embodiment of the present invention, the use of higher-precision sensors can improve the accuracy of data collection; the use of microprocessors can improve the speed and accuracy of data processing; in addition, data storage functions can be added to realize historical data query and analysis; and cloud platform technology is used to realize remote data monitoring and analysis.

[0061] Figure 6 FIG. 1 is a block diagram of a vehicle according to an embodiment of the present invention. Figure 6 As shown, the present invention also proposes a vehicle 000, comprising the reversing buzzer fatigue monitoring device 00 according to any embodiment of the present invention.

[0062] Among them, the vehicle's on-board main control can be integrated with the processing unit 200 in the reversing buzzer fatigue monitoring device 00.

[0063] The collection of environmental factors (temperature) and vehicle operating status data (sound intensity and vibration frequency) in this embodiment of the utility model allows for a more realistic assessment of the fatigue durability of the reversing buzzer. Furthermore, based on the changing trends of this data, failure risks can be identified in advance, allowing for prompt repair or replacement of the buzzer, thus avoiding potential safety hazards caused by sudden failure. This also helps to rationalize vehicle maintenance schedules and reduce maintenance costs, which is of great significance to vehicle safety and maintenance planning.

[0064] In summary, according to the reversing buzzer fatigue monitoring device and vehicle proposed in the embodiment of the present invention, the reversing buzzer fatigue monitoring device includes: a collection unit, a processing unit, and an alarm unit; the collection unit is located on the buzzer portion of the reversing buzzer, and the collection unit includes a sound sensor, a vibration sensor, and a temperature sensor; the processing unit includes a sound intensity receiving port, a vibration frequency receiving port, and a temperature receiving port, the sound intensity receiving port is connected to the sound sensor via a first detection line, the vibration frequency receiving port is connected to the vibration sensor via a second detection line, and the temperature receiving port is connected to the temperature sensor via a third detection line; the processing unit also includes an alarm connection port, which is electrically connected to the alarm unit. Thus, the sound intensity, vibration frequency, and ambient temperature of the reversing buzzer are collected in real time by the collection unit, and compared and analyzed by the processing unit, so as to monitor the working status of the reversing buzzer in real time, thereby realizing online monitoring of the working status of the reversing buzzer.
