Description

Technical Field

[0001] This invention relates to the field of smart helmet technology, specifically to a novel smart safety helmet and its intelligent control method. Background Technology

[0002] A safety helmet is a hat designed to protect the head from injuries caused by falling objects and other specific factors. It primarily functions to cushion impacts, absorb shock, and distribute stress, reducing injuries from falling objects and is widely used in the construction industry.

[0003] Existing safety helmets mainly consist of a shell, liner, and chin strap. A gap of 25-55 mm is typically left between the shell and liner to prevent the shell from contacting the wearer's head when it deforms due to impact from falling objects, thus achieving a good protective effect. However, ordinary safety helmets can only provide relatively simple protective functions and lack advanced technology.

[0004] Traditional helmets mainly consist of a shell, liner, and suspension system. With the development of the Internet of Things (IoT) and technological advancements, helmets have seen widespread application, leading to their development and a wide range of functions. Smart helmets are also gradually being applied in various fields. Smart helmets typically integrate sensors, communication modules, and other devices, providing some level of safety for the user, but also posing certain safety risks. For example, in the event of an accident, timely emergency calls for help can effectively shorten the waiting time for rescue. In one exemplary technology, a risk detection and distress signal device is installed on the helmet to determine if the user is in danger and release a distress signal. However, when the helmet collides with another object, both the helmet and the risk detection and distress signal device may be damaged, rendering the device malfunctioning and preventing automatic distress calls.

[0005] For example, application number CN202010648901.7 describes a smart safety helmet, characterized by comprising: a helmet body; a smart module assembly, the smart module assembly being formed as an open-side ring and fitted onto the helmet body, the smart module assembly including: a central mounting base, the central mounting base housing an inertial measurement module, and a camera module and / or a lighting module, the inertial measurement module including a rigid sensing bracket, a control circuit board, and an inertial sensor; a left mounting base, the left mounting base being coupled to one end of the central mounting base, the left mounting base defining multiple functional module mounting slots; a right mounting base, the right mounting base being coupled to the other end of the central mounting base, the right mounting base defining a battery pack mounting slot; and a battery assembly, the battery assembly being detachably mounted in the battery pack mounting slot. Its drawback is that the various sensors are distributed in a ring on the outer surface of the helmet, so in an impact, these external sensors will inevitably be the first to receive the impact, thus causing some or all of the smart components to lose function; consequently, the smart helmet will lose its corresponding function. Therefore, there is an urgent need to research a new type of smart safety helmet and a smart control method to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems by providing a novel smart safety helmet and a smart control method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a novel smart safety helmet, including a helmet shell;

[0008] A smart module assembly is located on the front side of the helmet shell. The smart module assembly includes a controller, a communication module, and a sensor module. The communication module, the sensor module, and the controller are all communicatively connected.

[0009] The intelligent module protection structure is formed on the helmet shell and placed around the intelligent module components. Before a collision or impact occurs, it is controlled by the sensor module to form a protective barrier around the intelligent module components.

[0010] The intelligent module protection structure includes a mounting cavity, which is a cavity set on the helmet shell and surrounding the intelligent module component. An airbag is provided in the mounting cavity and is placed in a retracted state within the mounting cavity. The airbag inflates before a collision. It also includes an inflation device, which is connected to the airbag via an air tube.

[0011] Furthermore, the inflation device is a gas cylinder, which is located on the rear side of the helmet shell. The gas cylinder outlet is equipped with a solenoid valve controlled by a controller, which controls the high-pressure gas in the gas cylinder to be inflated into the airbag.

[0012] Furthermore, the intelligent module component also includes a power function module, a display module, an audio module, a memory module, a button module, and a camera module; the power function module, display module, audio module, memory module, button module, and camera module are communicatively connected to the controller.

[0013] Furthermore, the sensor module includes an accelerometer, a distance sensor, and a collision sensor; the accelerometer, distance sensor, and collision sensor are communicatively connected to the controller; the accelerometer and distance sensor are disposed on the front side of the helmet shell; the collision sensor is disposed on the upper part of both sides of the helmet shell; and the distance sensor is used to detect the distance between the helmet shell and obstacles in front.

[0014] The sensor module also includes vital signs sensors, which are located inside the cap liner and include a heart rate sensor and a body temperature sensor. When worn, the heart rate sensor and body temperature sensor are in contact with the skin surface; the heart rate sensor and body temperature sensor are communicatively connected to the controller.

[0015] Furthermore, it also includes a solar charging component, which is electrically connected to the power function module. The solar charging component includes a solar panel, which is fixedly installed on the top of the helmet shell. The solar charging component is communicatively connected to the controller and is controlled to charge the lithium battery in the power function module.

[0016] Furthermore, it also includes a lighting module, which includes a front light, a rear warning light, and a light sensor module. The front light, rear warning light, and light sensor module are communicatively connected to the controller. The front light is located on the front side of the helmet shell, the rear warning light is located on the rear side of the helmet shell, and the light sensor module is integrated into the smart module assembly.

[0017] Furthermore, the communication module includes one or more of Bluetooth, WIFI, 4G / 5G, and GPS.

[0018] A control method for a new type of smart safety helmet includes the following steps:

[0019] 1) Includes a mobile terminal and a smart safety helmet, wherein the communication module in the safety helmet is communicatively connected to the mobile terminal;

[0020] 2) Based on the sensor module's detection of the smart safety helmet's status, if the helmet is at risk of impact, gas is instantly injected into the airbag, causing the airbag to pop out from the mounting cavity and form a protective barrier around the smart module components, and a distress message is sent to the distress platform;

[0021] 3) The controller actively activates the heart rate sensor and body temperature sensor to monitor and record the user's heart rate and body temperature. If the heart rate and body temperature monitoring information is abnormal, a personnel crisis alarm is sent to the distress platform.

[0022] 4) Obtain the geographical coordinates and time information of the time of the accident; add the obtained information to the information sending template to form the distress message;

[0023] 5) Obtain image information of the accident scene; add the obtained image information to the information sending template to form the distress message;

[0024] 6) Detect whether the preset mobile terminal is online; if the mobile terminal is online, send a distress message to the mobile terminal so that the distress message can be sent to the distress platform through the mobile terminal; if the mobile terminal is offline, send a distress message to the distress platform through the preset distress application in the communication module.

[0025] Furthermore, in step 2), the acceleration sensor detects the acceleration value of the smart safety helmet and compares it with a preset acceleration threshold. When the threshold is reached, a first trigger signal is sent to the controller. The distance sensor is activated according to the first trigger signal. The distance sensor senses the distance to the obstacle in front of it and calculates the collision time based on the real-time speed and acceleration values. The distance sensor then sends a second trigger signal to the controller. Upon receiving the second trigger signal, the controller compares the collision time with the inflation time and controls the airbag to inflate and deploy instantaneously before the collision time arrives.

[0026] Furthermore, in step 2), the collision sensor detects a collision with the smart safety helmet, sends a firing signal to the controller, and the controller immediately controls the airbag to inflate and deploy.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This invention relates to a smart helmet that adds an intelligent control system structure to the traditional helmet shell, liner, and suspension structure. Inside the shell, a high-precision integrated circuit board, front light, rear warning light, collision trigger sensor, and solar charging panel are added. The circuit board integrates a power module, communication module, display module, lighting module, audio module, light sensor module, collision module, acceleration module, memory module, and button module, thus enriching the application scenarios of the smart safety helmet.

[0029] This invention relates to an intelligent safety helmet with an intelligent module protection structure. Through a sensor module, the helmet's status is detected and assessed. Firstly, when the collision sensor is impacted and exceeds a threshold, the airbag is deployed to protect the intelligent module components, preventing damage during an impact. Secondly, before a collision occurs, the distance sensor is triggered based on acceleration data. The distance sensor receives a pre-collision signal and sends a control signal to inflate the airbag, protecting the intelligent module components and preventing damage during an impact. After an impact, the protected intelligent module components, in good condition, transmit various information about the impact as a distress signal to a distress platform, effectively achieving automatic distress.

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] A novel smart safety helmet includes a helmet shell 1. The helmet shell 1 is generally semi-circular in shape and has an internal cavity. When worn, the helmet shell 1 is fastened to the head. A liner 21 is disposed inside the helmet shell 1, and a chin strap is attached to the underside of the liner 21. The invention incorporates a smart module component 2 on the helmet shell 1.

[0039] Intelligent module component 2 is located on the front side of helmet shell 1, such as Figure 1 As shown, a platform surface protruding forward is formed on the front side of the helmet shell 1. The platform surface is connected to the helmet shell 1 through side edges, thus forming a shell with an internal space between the platform surface and the side edges. The intelligent module component 2 is disposed within this shell. The intelligent module component 2 includes a controller 3, a communication module 4, and a sensor module 5. The communication module 4 and sensor module 5 are all communicatively connected to the controller 3. Specifically, the controller 3 is disposed within the aforementioned shell, and the communication module 4 and sensor module 5 are integrated around the controller 3, such as... Figure 1 , 2 As shown, the intelligent module component 2 also includes a power function module 12, a display module 13, an audio module 14, a memory module 15, a button module 16, and a camera module 17; the power function module 12, display module 13, audio module 14, memory module 15, button module 16, and camera module 17 are communicatively connected to the controller 3. The power function module 12 can be located in the cavity between the helmet shell 1 and the helmet liner 21, or it can be integrated with the controller 3 into the aforementioned shell, and the power function module 12 supplies power to each module.

[0040] Traditional smart helmets have short battery life, which cannot meet the needs of long-term operation. To overcome this deficiency, this embodiment includes a solar charging component, such as... Figure 1 , 2 As shown, a solar panel 23 is installed on the top of the helmet shell 1 to facilitate sunlight exposure. The solar panel 23 converts solar energy into electrical energy and stores it in the power function module 12. The solar charging component is electrically connected to the power function module 12. The solar charging component includes the solar panel 23, which is fixedly installed on the top of the helmet shell 1. The solar charging component is communicatively connected to the controller 3 and is controlled to charge the lithium battery in the power function module 12. A precision circuit boosts the voltage of the solar panel to a suitable voltage before charging the device battery. The power module provides different output voltages to meet the operational needs of various modules in the smart helmet. Figure 4 , 5As shown, the Power_Module is used to power the smart helmet. The power module circuit design supports battery power, button power-on, and solar module charging, thus enabling long-term operation. The power module is functionally connected to the internal power supply interface and SADC interface of the chip control module through the battery circuit. The SADC function within the chip control module can monitor the battery level and display it on the screen. If the battery level is detected as low, the software can control the solar charging module via GPIO to start charging the battery; if the battery is detected as fully charged, the software can also control the solar charging module via GPIO to stop charging the battery.

[0041] Furthermore, traditional smart helmets have relatively limited functionality and cannot meet diverse market demands. As an improvement, this embodiment includes a lighting module, which comprises a front light 24, a rear warning light 25, and a light sensor module 26, such as... Figure 1 As shown, a front light is installed on the front side of the helmet shell 1, and a rear warning light 25 is installed on the rear side of the helmet shell 1. The front light 24, rear warning light 25, and light sensor module 26 are communicatively connected to the controller 3. The light sensor module 26 is integrated into the intelligent module component 2. In some usage scenarios, the front light 24 is manually turned on. A button module 16 is provided on the platform surface, which can directly control the front light 24 or the rear warning light 25 to turn on and off. It can be understood that the rear warning light 25 can use a red warning color to warn those behind while riding or working. The front light 24 is used to provide supplemental lighting in low-light conditions.

[0042] The KEY_Module 16 is also used to control the working status of the smart helmet, such as turning the helmet on and off, turning on the helmet lights, and enabling one-button emergency dialing. The KEY_Module 16 is functionally connected to the GPIO interface of the chip control module through a button switch circuit, and each function is implemented by inputting command interrupt signals through the button switches.

[0043] In other use cases, such as Figure 2 As shown, a light-sensing module 26 is provided on the platform surface, such as... Figure 5 As shown, the light sensor module 26 is actually an ambient light sensor module. This Ambient_Light_Sensor_Module is also used to control the working state of the smart helmet. When wearing the helmet in a dark environment, the ambient light sensor module accurately monitors the ambient light signal and can activate the LED. This means the front light 24 can be set to an automatic on / off mode. Based on the ambient light sensor's detection of the surrounding light, if the brightness falls below a set value, the front light 24 can be automatically turned on. Figure 5As shown, based on the dimming algorithm software, the dynamic adjustment of the smart table lamp light is achieved through the GPIO_PWM interface function inside the control module. The ambient light sensor module is functionally connected to the GPIO interface of the I2C controller 3 inside the control module through the I2C_CLK, I2C_SDA and INT control signals.

[0044] Specifically, such as Figure 5 As shown, the LED module includes a front light 24 and a rear light, used to output LED light. The front light of the smart helmet can be used for illumination, and the rear light is used for work safety warning lights. The front light is a high-power LED, which is supplied with a suitable voltage through a boost power supply device, and the boost power supply device is connected to the corresponding function of the GPIO_PWM interface of the controller 3. The safety warning light is a regular LED, which is directly connected through the corresponding function of the GPIO_PWM interface. The LED module can control the output of PWM digital signals and change the duty cycle of the pulse signal by controlling the GPIO_PWM function, thereby controlling the current output of the boost power supply and thus adjusting the brightness of the lights.

[0045] Furthermore, to enrich the functionality of this smart helmet, the Audio_Module 14 is used for audio output and voice input; it can achieve two-way voice communication through the communication module 4. Figure 5 As shown, the audio module 14 is designed with SPK and MIC circuits, and is functionally connected to the audio CODEC interface of the control module 3 through HPOUTP, HPOUTN, MIC_BIAS, MICP, and MICN. A speaker 35 and a microphone are provided on one side of the platform, enabling voice calls between smart helmets and between smart helmets and other mobile terminals 37 via the communication module 4, facilitating real-time communication and enabling instant communication between connected groups when traveling together.

[0046] This smart safety helmet features real-time recording capabilities and is equipped with a camera module 17. A camera 33 is located at the front of the platform, allowing for the recording of the real-time situation on the front of the helmet. This device includes, but is not limited to, a camera 33 positioned on the front of the helmet shell 1. In other embodiments, a camera 33 can also be positioned on the rear of the helmet shell 1, enabling simultaneous recording of both the front and rear sides. An SD memory card slot 36 is located on one side of the platform. In actual use, the image data captured by the camera 33 is stored in the memory card within this slot via the controller 3. The Camera_sensor_Module enables taking photos and recording videos of the surrounding environment and can automatically save and upload the data via wireless communication. Figure 5As shown, the camera module 33 is functionally connected to the CIM_DVP controller 3 and I2C controller 3 interfaces within the chip control module through the camera 33 data signal CIM_DATA (D0-D7), camera 33 clock signal CAM_MCLK, camera 33 horizontal synchronization signal HSYNC, camera 33 vertical synchronization signal VSYNC, CAM_I2C (SDA, SCL), and XSHUTDOWN signal lines. Specifically, the SD_Card_Module storage module is used for smart helmet data storage and can store photo, video, and audio data. The storage module is designed with SD_Card circuitry and is functionally connected to the SD / MMC controller 3 interface within the chip control module through SDIO_CMD, SDIO_CLK, and SDIO_DATA (0-4). An APP application can be installed on a mobile phone or PC and wirelessly connected through the communication module 4; it can monitor and command on-site personnel in real time; and through the camera 33 function of the helmet, managers can view real-time video of the work site, equipment, and personnel safety anytime and anywhere.

[0047] Furthermore, an LCD display screen 32 is located below the camera 33 on the platform surface. This LCD display screen 32 is driven by the display module 13. Specifically, the LCD_Module 13 is used to display the smart helmet's status information, such as time, battery level, and recorded video. The LCD display screen 32 within the display module 13 communicates with the MIPI_DSI interface within the control module; for example... Figure 5 As shown, four sets of data signals DSI_MIPI_DATA0+, DSI_MIPI_DATA0-, DSI_MIPI_DATA1+, DSI_MIPI_DATA1-, DSI_MIPI_DATA2+, DSI_MIPI_DATA2-, DSI_MIPI_DATA2+, and DSI_MIPI_DATA2-, along with a set of clock signal lines DSI_MIPI_CLK+ and DSI_MIPI_CLK-, are functionally connected to the MIPI_DSI interface within controller 3, corresponding one-to-one. The internal RTC controller 3 and the external clock crystal form a real-time clock circuit, providing real-time time, alarm clock, and timed power-on / off functions.

[0048] Specifically, such as Figure 4 , 5As shown, the communication module 4 is used for wireless data communication; the communication module 4 includes a WIFI module 28, a BT module 27, a 4G / 5G communication module 29, and a GPS module 30. The WIFI module connects to the SDIO interface of the controller 3 within the chip control module via SDIO_CMD, SDIO_CLK, and SDIO_DATA (0-4) to enable the device to connect to the Internet and wirelessly transmit data, thereby achieving interconnection with the mobile terminal 37. The BT module connects to the UART and PCM interfaces of the controller 3 within the chip control module via PCM_CLK, PCM_SYNC, PCM_DO, PCM_DI, UART_RX, UART_TX, UART_RTS, and UART_CTS to enable Bluetooth 27 wireless data transmission. The 4G / 5G communication module 4 connects to the USB / UART interface of the controller 3 within the chip control module via USBDP, USBDN, or UART_RX and UART_TX to enable voice communication and data transmission. The GPS module is functionally connected to the UART / I2C interface of controller 3 within the chip control module via UART_TX, UART_RX, or I2C (SDA, SCL).

[0049] In terms of data monitoring and safety monitoring, the intelligent safety helmet of this invention incorporates sensors for sensing external situations, specifically including an acceleration sensor 18, a distance sensor 19, and a collision sensor 20. The acceleration sensor 18, distance sensor 19, and collision sensor 20 are communicatively connected to the controller 3. The acceleration sensor 18 and distance sensor 19 are located on the front side of the helmet shell 1, and the collision sensor 20 is located on the upper sides of both sides of the helmet shell 1. The distance sensor 19 is used to detect the distance between the helmet shell 1 and obstacles in front.

[0050] The Collision_Sensor_Module 20 module 5 is used to detect and determine the safety status of a person wearing a helmet. When the helmet is impacted by an external force, the collision sensor 20 is triggered to generate an impact signal, which is sent to the chip control module. After detecting the collision signal, the software program in the chip control module will quickly generate a distress signal. At this time, the rear LED light of the smart helmet will flash, the audio module 14 will emit a distress sound, and the communication module 4 will automatically send a rescue command to the monitoring system and emergency contacts. Furthermore, the GPS 30 module can provide accurate positioning for rapid rescue. At the same time, in order to avoid damage to the smart module component 2 during a collision, which would affect the subsequent issuance of the distress signal, the collision sensor 20 is also used as a trigger signal released by the smart module protection structure 6. That is, when a collision is detected, the collision sensor 20 needs to measure the severity of the collision. By comparing it with a set value, if the collision is below the set value, no alarm is issued. If the collision exceeds the set value, a distress signal is generated, and the smart protection module component is triggered to protect the smart module and prevent it from being damaged by the collision. The collision sensor module 20 supports comprehensive monitoring functions, with one detection circuit installed at the front, back, left, right, and top of the helmet; the generated OUT_INT-4 collision interrupt signals are functionally connected to the GPIO interface in the chip control module.

[0051] The intelligent module protection structure 6, formed on the helmet shell 1 and positioned around the intelligent module component 2, forms a protective barrier around the intelligent module component 2 under the control of the sensor module 5 before a collision or impact occurs; specifically, such as... Figure 1 , 2 The intelligent module protection structure 6 includes a mounting cavity 7, which is a cavity disposed on the helmet shell 1 and surrounding the intelligent module component 2. An airbag 8 is housed within the mounting cavity 7. During normal use, the airbag 8 is retracted within the mounting cavity 7, and the surface of the mounting cavity 7 is covered by a fracturing shell 31. This fracturing shell 31 covers the surface of the mounting cavity 7, creating a smooth surface around the intelligent module component 2. When painting or other operations are performed on the helmet surface, the mounting cavity 7 is covered by paint, forming a hidden shape. In the event of a collision, the airbag 8 inflates before impact, causing the fracturing shell 31 on the surface of the mounting cavity 7 to be pushed out and broken, allowing the airbag 8 to easily deploy. Figure 3 As shown, when the airbag 8 deploys, it forms a ring of anti-collision pads surrounding the smart module, thereby protecting the smart module component 2 from damage upon impact; it also includes an inflation device 9, which is connected to the airbag 8 via an air tube 10. In some embodiments, such as Figure 1 , 3As shown, the inflation device 9 is a gas cylinder, which is located on the rear side of the helmet shell 1. A solenoid valve 11, controlled by a controller 3, is located at the outlet of the gas cylinder. The solenoid valve 11 controls the injection of high-pressure gas from the gas cylinder into the airbag 8. The opening of the solenoid valve 11 is controlled by the controller 3. High-pressure air is stored in the gas cylinder. When a collision occurs, the controller 3 sends a control signal to open the solenoid valve 11, causing compressed gas to instantly inflate into the airbag 8, forming a shock-absorbing pad surrounding the intelligent module component 2.

[0052] Furthermore, in some embodiments, the sensor module 5 further includes a vital signs sensor 22, which is disposed inside the cap liner 21, such as... Figure 3 The diagram shows the helmet liner 21 being removed downwards from the helmet shell 1. The vital signs sensor 22 includes a heart rate sensor and a body temperature sensor. When worn, the heart rate sensor and body temperature sensor are positioned in contact with the skin surface, as shown. Figure 3 As shown in the illustration, the vital signs sensor 22 is attached to the temple area to collect the wearer's heart rate and body temperature data; the heart rate sensor and body temperature sensor are communicatively connected to the controller 3, and the controller 3 records and uses the vital signs data such as heart rate.

[0053] As a practical application of the accelerometer sensor 18, specifically, the Acceleration_Sensor_Module 5 is used to detect sudden deceleration of a helmet-wearing rider and provide an automatic deceleration warning light. The OUT_INT interrupt signal interface of the accelerometer sensor module 5 is functionally connected to the GPIO port within the chip control module. When the accelerometer module detects deceleration, it generates an interrupt signal for the chip control module; the chip control module's software responds quickly and then activates the rear LED light of the smart helmet via the GPIO function interface port; thereby reducing the risk of rear-end collisions during deceleration, greatly increasing nighttime riding safety, and enhancing active safety protection.

[0054] Specifically, the novel smart helmet technology and device includes a controller (SOC_X2600_Module) 3, a power function module (Power_Module) 12, a display module (LCD_Module) 13, an ambient light sensor module (Ambient_LightSensor_Module), a collision sensor module (Collision_Sensor_Module) 20, an acceleration sensor module (Acceleration_Sensor_Module) 18, a button module (KEY_Module) 16, a camera sensor module (Camera_sensor_Module), an audio module (Audio_Module) 14, a storage module (SD_Card_Module), a communication module (GPS30_Positioning_Module, WIFI28_BT_Module, 4G / 5G29_Communication_Module), an LED light module (LED_Module), and a monitoring system module; all modules are designed with high-performance, high-precision circuitry.

[0055] The controller 3 is feature-rich. In this embodiment, the controller 3 uses the X2600 chip, which is a low-power, high-performance, and highly integrated processor. It integrates an H264 decoder, a JPEG codec, and a 2D processing engine. Internally, it has an Audio_CODEC controller 3, a PCM controller 3, and supports analog signal input and digital audio signal output. Internally, it has a Display controller 3, which supports the MIPI_DSI display output interface and a Camera input interface. It also has an SDIO controller 3, an RTC controller 3, and a variety of flexibly configurable interfaces (GPIO, I2C, UART, PWM, SADC, USB).

[0056] Based on the above hardware architecture, this invention also proposes a novel control method for a smart safety helmet, comprising the following steps:

[0057] 1) Includes a mobile terminal 37 and a smart safety helmet, wherein the communication module 4 in the safety helmet is communicatively connected to the mobile terminal 37; that is, an APP application can be installed on a mobile phone or PC and wireless connection can be achieved through the communication module 4;

[0058] 2) Based on the sensor module 5 detecting the status of the smart safety helmet, if the helmet is at risk of impact, gas is instantly injected into the airbag 8, causing the airbag 8 to pop out from the mounting cavity 7 and form a protective barrier around the smart module component 2, and send a distress message to the distress platform.

[0059] Furthermore, in some collision scenarios, the collision occurs between the front of the helmet and an obstacle. Since the present invention centrally houses the intelligent module component 2 at the front of the helmet shell 1, it is necessary to ensure the intact functionality of this intelligent module component 2 after the collision. Therefore, protection of the intelligent module component 2 is required during the collision process. Specifically, in actual use, the acceleration sensor 18 detects the acceleration value of the intelligent safety helmet. The acceleration sensor 18 continuously monitors the movement speed during use and compares the real-time acceleration with a preset acceleration threshold. Upon reaching the threshold, a first trigger signal is transmitted to the controller 3, indicating a sudden change in acceleration due to the collision. The distance sensor 19 is activated based on the first trigger signal. Since, in actual collisions, the helmet is not always the first point of contact in all collisions, but rather the position of the helmet relative to the obstacle after the collision... When the distance between the obstacles decreases and the helmet collides again, the acceleration sensor 18 is used as the first trigger signal to trigger the distance sensor 19 to work. The distance sensor 19 senses the distance to the obstacle in front and calculates the time of the impending collision based on the real-time speed and acceleration values. It then sends a second trigger signal to the controller 3. Upon receiving the second trigger signal, the controller 3 compares the collision time with the inflation time and controls the airbag 8 to inflate and deploy just before the collision time arrives. In actual control, when the operator collides, the acceleration sensor 18 detects abnormal speed changes and sends the first trigger signal. If the helmet collides with the obstacle after a certain period of time, the distance sensor 19 calculates the collision distance and speed, and the controller 3 controls the airbag 8 to inflate just before the collision, thereby achieving the best protective effect.

[0060] 3) The controller 3 actively activates the heart rate sensor and body temperature sensor to monitor and record the user's heart rate and body temperature. If the heart rate and body temperature monitoring information is abnormal, a personnel crisis alarm is sent to the rescue platform. Under normal use, the heart rate sensor and body temperature sensor can be passively activated to monitor the wearer's physiological information. However, in the event of a collision, in order to detect the wearer's safety, the heart rate and body temperature monitoring and recording can be actively activated simultaneously by the trigger signal generated by the collision. When sending the rescue information, the wearer's physiological information will also be sent so that rescuers can rescue according to the situation.

[0061] 4) Obtain the geographical coordinates and time information of the time of the accident; add the obtained information to the information sending template to form the distress message;

[0062] 5) Obtain image information of the accident scene; add the obtained image information to the information sending template to form the distress message; in actual use, the GPS30 module function is used to accurately locate the accident location to facilitate rapid rescue, and the camera33 records the collected accident process impact data and sends the distress message to the distress platform along with it.

[0063] 6) Detect whether the preset mobile terminal 37 is online; if the mobile terminal 37 is online, send a distress message to the mobile terminal 37 to send the distress message to the distress platform through the mobile terminal 37; if the mobile terminal 37 is offline, send a distress message to the distress platform through the preset distress application in the communication module 4.

[0064] As another embodiment of the control method for a smart safety helmet, this embodiment is largely the same as the aforementioned embodiment, except that in step 2), the collision sensor 20 detects a collision with the smart safety helmet and sends a firing signal to the controller 3, which then immediately controls the airbag 8 to inflate and deploy. This embodiment is applied when a collision occurs from the top or sides of the helmet. When a collision occurs from the top of the helmet, the front smart module component 2 is not the first point of impact and is therefore less likely to be damaged. For safety, upon collision, the collision sensor 20 sends a feedback signal, and the controller 3 directly controls the airbag 8 to deploy.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the embodiments of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
