[0005] Disadvantage 3: Inflexible alarm processing. The existing system's alarm processing method is relatively simple and cannot be flexibly adjusted according to actual conditions (such as the device is not worn or the heart rate is abnormal), resulting in insufficient system reliability.

[0006] Disadvantage 4: Lack of remote management capabilities. The existing system lacks remote management functions. Administrators cannot monitor and handle alarm situations in real time through the background, resulting in inefficient on-site management. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] Figure 1 A structural schematic diagram of an alarm system based on UWB ranging in the present application is shown.

[0027] like Figure 1 As shown, the present application discloses an alarm system based on UWB ranging, comprising: UWB base station, UWB terminal, server terminal and user terminal, wherein: The UWB base station includes a main control module, a base station UWB module, a base station communication module, a voice module, an alarm light and a base station power supply module, which are used to receive command data from a server terminal and send UWB base station data to the server terminal; The UWB terminal is communicatively connected with the UWB base station, and specifically includes a vibration motor, a terminal UWB module, a terminal voice module, a heart rate module and a terminal power supply module, and is used to receive transmission data from the UWB base station and the server terminal, and send UWB terminal data to the server terminal; The server terminal is in communication connection with the UWB base station and the UWB terminal, and is used for transmitting and storing communication data; The user terminal is communicatively connected to the server terminal and is used for receiving transmission data from the server terminal and sending management data to the server terminal.

[0028] It should be noted that, in this embodiment, the main control module includes a WIFI module, and the base station communication module includes a 4G mobile communication module, wherein the WIFI module is connected to the base station UWB module through a serial port, and the 4G mobile communication module is communicatively connected to the WIFI module through a USB interface; the UWB base station is used for distance detection and alarm trigger identification, and the UWB terminal is used to monitor the wearer's heart rate data and alarm trigger identification, wherein the UWB base station and the UWB terminal perform real-time distance measurement through UWB communication to obtain the detection distance.

[0029] Furthermore, when the UWB base station communicates with the UWB terminal via UWB, the UWB base station and the UWB terminal identify whether to trigger an alarm based on the detection distance, wherein when the detection distance is less than or equal to the operating range and the UWB terminal detects the heart rate, the UWB base station triggers the operation alarm light prompt and the operation voice prompt, and the UWB terminal synchronously triggers the vibration voice prompt; when the detection distance is less than or equal to the operating range and the UWB terminal does not detect the heart rate, the UWB base station triggers the cancellation of the alarm response based on a preset mechanism, and the UWB terminal triggers the wearing alarm light and the wearing voice prompt.

[0030] Furthermore, the user terminal monitors and displays the detection distance, heart rate data and alarm status of the UWB base station and the UWB terminal in real time. When a false alarm is detected or the device is not worn, the user terminal sends a cancel alarm instruction and / or a device left behind instruction to the server terminal, and the server terminal sends the cancel alarm instruction and / or the device left behind instruction to the UWB base station and the UWB terminal.

[0031] Specifically, at a construction site, a heavy excavator is equipped with a UWB base station, and the operator wears a UWB terminal (such as a UWB bracelet). In actual application, the UWB base station is initialized: After the excavator is started, the UWB base station automatically turns on and connects to the background server through the 4G mobile communication module. The base station obtains the alarm distance threshold (such as 5 meters) and heart rate detection configuration from the server (such as canceling the alarm if there is no heart rate for 2 consecutive minutes). UWB terminal initialization: After the UWB bracelet worn by the worker is turned on, it starts to detect the heart rate.

[0032] Specifically, if the heart rate is not detected within "5" minutes, the bracelet will give a voice prompt "Please wear the device correctly". Accordingly, the server terminal is initialized: the server loads the configuration information of the excavator base station and the worker's bracelet, and prepares to receive distance measurement data and heart rate data.

[0033] Furthermore, the application scenario of real-time distance measurement and heart rate detection corresponds to workers working near excavators, and the UWB base station and the bracelet communicate in real time, where UWB distance measurement: the UWB base station and the worker's bracelet perform real-time distance measurement through UWB communication, and calculate the distance between the two to obtain the detection distance. Assuming that the operating range corresponds to "4" meters, when the UWB base station detects that the distance of the UWB bracelet is "4" meters (entering the alarm range), it enters the heart rate detection, where the UWB bracelet worn by the operator monitors the heart rate data in real time through the heart rate detection device, and analyzes the heart rate data through the heart rate detection algorithm corresponding to the heart rate module to determine whether the heart rate is normal (such as a heart rate value of 70 beats / minute).

[0034] When judging the detection distance and heart rate data, when the detection distance is less than or equal to "4" meters and the UWB terminal detects the heart rate, the UWB base station triggers the operation alarm light prompt and the operation voice prompt, and the UWB terminal synchronously triggers the vibration voice prompt; when the detection distance is less than or equal to "4" meters and the UWB terminal does not detect the heart rate, the UWB base station triggers the cancellation of the alarm response based on the preset mechanism, and the UWB terminal triggers the wearing alarm light and the wearing voice prompt. Specifically, the UWB base station reports the distance measurement data (4 meters) and heart rate data (70 times / minute) to the server terminal through the 4G mobile communication module for data transmission.

[0035] Furthermore, the corresponding application scenario when performing alarm triggering and processing is: a worker enters the dangerous operating range of an excavator, and an alarm is triggered based on heart rate data.

[0036] Specifically, in this embodiment, when the heart rate data shows a heart rate, the UWB base station detects that the worker has entered the alarm range (4 meters) and the heart rate data is normal (70 times / minute), and starts triggering the alarm light and voice prompt to remind the excavator operator "Please note that there are workers nearby, 4 meters away"; further, after the operating worker's UWB bracelet receives the alarm signal, it vibrates and issues a voice prompt "You have entered the danger zone, please evacuate as soon as possible."

[0037] When the UWB base station detects that the worker has entered the alarm range (4 meters) and there is no heart rate data, assuming that the worker has not worn the UWB bracelet correctly, the base station detects that the worker has entered the alarm range (4 meters) but has no heart rate data. At this time, it responds according to the preset processing method (such as canceling the alarm if there is no heart rate for 2 consecutive minutes) to cancel the alarm of the UWB base station, and the corresponding UWB bracelet worn by the worker will continue to prompt "Please wear the device correctly and leave the danger zone as soon as possible."

[0038] Furthermore, the user terminal is communicatively connected with the server terminal for receiving transmission data from the server terminal and sending management data to the server terminal, wherein the server terminal detects abnormal heart rate for "5" consecutive minutes (such as no heart rate data), and notifies the administrator corresponding to the on-site user terminal for processing, wherein the administrator confirms the on-site situation through the APP, finds that the bracelet has been left at the construction site, and issues a command to cancel the alarm.

[0039] Furthermore, the application scenario of remote management and alarm cancellation of user terminals is that the administrator monitors and handles alarm situations remotely.

[0040] Specifically, in this embodiment, the server terminal monitors the detection distance (distance measurement data), heart rate data and alarm status of the excavator UWB base station and the UWB bracelet worn by the worker in real time. If the server terminal detects that a UWB bracelet has no heart rate data for "5" consecutive minutes, it will be marked as abnormal. For the handling of false alarms, the administrator checks the alarm details through the APP and finds that the bracelet has been left at the construction site. At this time, it is a false alarm state. The user terminal sends a cancel alarm command through the APP, and the UWB base station stops the alarm.

[0041] Furthermore, in case of lost equipment, the administrator notifies on-site personnel to find the lost wristband and take it away from the danger zone to resume normal operations at the construction site, ensuring the accuracy of subsequent alarms.

[0042] Figure 2 A flow chart of an alarm method based on UWB ranging in the present application is shown.

[0043] like Figure 2As shown, the present application discloses an alarm method based on UWB ranging, which is applied to a UWB base station. The method comprises the following steps: S202, performing UWB communication based on the UWB terminal to calculate the distance between the two to obtain a detection distance; S204, acquiring heart rate data detected by the UWB terminal, and triggering an alarm prompt based on the detection distance and the heart rate data; S206, when the detection distance is less than or equal to the operation range and the heart rate data shows that the heart rate is detected, the UWB base station triggers an operation alarm light prompt and an operation voice prompt; S208: When the detection distance is less than or equal to the operating range and the heart rate data shows that no heart rate is detected, the UWB base station triggers a cancellation alarm response based on a preset mechanism.

[0044] It should be noted that in this embodiment, when the UWB base station is used, it performs UWB communication with the UWB terminal to calculate the distance between the two to obtain the detection distance, and when performing UWB communication with the UWB terminal, it obtains the heart rate data detected by the UWB terminal, thereby triggering an alarm prompt based on the detection distance and the heart rate data.

[0045] Specifically, when the detection distance is less than or equal to the operating range and the heart rate data shows that the heart rate is detected, the UWB base station triggers an operation alarm light prompt and an operation voice prompt; and when the detection distance is less than or equal to the operating range and the heart rate data shows that the heart rate is not detected, the UWB base station triggers a cancellation alarm response based on a preset mechanism. In the above embodiment, the operating range includes "4" meters. When the UWB base station detects that the worker enters the alarm range (4 meters) and the heart rate data is normal (70 times / minute), the alarm light and voice prompt are triggered to remind the excavator operator "Please note that there are workers nearby, 4 meters away"; and when the UWB base station detects that the worker enters the alarm range (4 meters) and there is no heart rate data, assuming that the worker does not wear the UWB bracelet correctly, the base station detects that the worker enters the alarm range (4 meters) but has no heart rate data. At this time, a response is made according to the preset processing method (such as canceling the alarm if there is no heart rate for 2 consecutive minutes) to cancel the alarm of the UWB base station.

[0046] According to an embodiment of the present invention, the UWB base station triggers a cancellation alarm response based on a preset mechanism, specifically including: When the detection distance is less than or equal to the operating range and the heart rate data shows that no heart rate is detected, starting a timing response; When the heart rate data shows that no heart rate is detected within the accumulated time after timing, a cancellation alarm response is triggered based on the preset mechanism, wherein the preset mechanism includes a cancellation alarm mechanism when there is no heart rate within the accumulated time.

[0047] It should be noted that, in this embodiment, how to trigger the cancellation of the alarm response is specifically explained. Specifically, when the detection distance is less than or equal to the operating range and the heart rate data shows that no heart rate is detected, the timing response is started. When the heart rate data shows that no heart rate is detected within the cumulative time after timing (for example, 2 minutes), the cancellation of the alarm response is triggered based on the preset mechanism, wherein the preset mechanism includes a mechanism to cancel the alarm if there is no heart rate within the cumulative time.

[0048] According to an embodiment of the present invention, the method further includes sending the detection distance and the alarm response to the server terminal, and receiving management data sent by the server terminal, wherein the management data includes an alarm cancellation instruction and / or a device lost instruction.

[0049] It should be noted that, in this embodiment, the UWB base station also has a server terminal for data communication, wherein the detection distance and alarm response are specifically sent to the server terminal, and management data sent by the server terminal is received, and the management data includes canceling the alarm instruction / or the device lost instruction.

[0050] Figure 3 A flow chart of an alarm method based on UWB ranging in the present application is shown.

[0051] like Figure 3 As shown, the present application discloses an alarm method based on UWB ranging, which is applied to a UWB base station. The method comprises the following steps: S302, performing UWB communication based on the UWB base station to calculate the distance between the two to obtain a detection distance; S304, triggering an alarm prompt based on the detection distance and the detected heart rate data; S306, when the detection distance is less than or equal to the operating range and the heart rate is detected, the UWB terminal triggers a vibration voice prompt; S308: When the detection distance is less than or equal to the operating range and the heart rate is not detected, the UWB terminal triggers a wearing alarm light and a wearing voice prompt.

[0052] It should be noted that in this embodiment, in this embodiment, when the UWB terminal is used, it communicates with the UWB base station by UWB to calculate the distance between the two to obtain the detection distance, and when communicating with the UWB base station by UWB, it obtains heart rate data based on the heart rate detection device, thereby triggering an alarm prompt based on the detection distance and the heart rate data.

[0053] Specifically, in this embodiment, when the heart rate data shows a heart rate, the UWB terminal detects that the worker has entered the alarm range (4 meters), and the heart rate data is normal (70 times / minute). After the operating worker's UWB bracelet receives the alarm signal, it vibrates and issues a voice prompt "You have entered the danger zone, please evacuate as soon as possible."

[0054] When the UWB terminal detects that a worker has entered the alarm range (4 meters) but there is no heart rate data, assuming that the worker has not worn the UWB bracelet correctly, it detects that the worker has entered the alarm range (4 meters) but there is no heart rate data, corresponding to the UWB bracelet worn by the worker, and it will continue to prompt "Please wear the device correctly and leave the danger zone as soon as possible."

[0055] According to an embodiment of the present invention, the method further includes sending the detection distance and the alarm response to the server terminal, and receiving management data sent by the server terminal, wherein the management data includes an alarm cancellation instruction and / or a device lost instruction.

[0056] It should be noted that, in this embodiment, the UWB terminal also communicates data with the server terminal, wherein the detection distance and alarm response are specifically sent to the server terminal, and management data sent by the server terminal is received, wherein the management data includes canceling the alarm instruction and / or the device lost instruction.

[0057] Furthermore, the application scenario of this embodiment is as follows: first, the system is started and initialized. After the excavator UWB base station and the UWB bracelet worn by the worker are turned on, they automatically connect to the background server, load the configuration information, and ensure the normal operation of the system.

[0058] Furthermore, real-time distance measurement and heart rate detection are carried out: the UWB base station communicates with the UWB bracelet in real time to detect distance and heart rate, ensuring timely alarm when workers enter dangerous areas. The alarm triggering and processing correspond to: when workers enter dangerous areas, the system reminds operators and workers through alarm lights, voice prompts and vibrations to ensure construction safety. If the equipment is not worn or the heart rate is abnormal, the system flexibly handles it according to preset rules to avoid false alarms.

[0059] Furthermore, remote management and alarm cancellation, the administrator of the user terminal monitors the alarm status in real time through the background, remotely handles false alarms and equipment loss, and ensures efficient operation of the system. Through the above embodiment, the whole process automation from system initialization, real-time ranging, heart rate detection to alarm triggering and remote management is realized, which significantly improves the safety and management efficiency of the heavy machinery construction environment.
