At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0026] As described in the background art, when the safety helmet is taken off by the operator in violation of regulations or is not worn correctly, the operator cannot be reminded, resulting in a major safety hazard.

[0027] Based on the above reasons, the present application provides a smart safety helmet that can actively remind workers when they take it off illegally or wear it incorrectly, thereby reducing safety hazards.

[0028] In one embodiment, as shown in FIG1 , a smart helmet is provided, including: a helmet body 110, a wearing detection module 120, a micro control unit 130 and an alarm module 140, wherein the wearing detection module 120 is fixedly arranged on the helmet body 110, and the wearing detection module 120 is used to generate a wearing signal according to a wearing action; the micro control unit 130 is fixedly arranged on the helmet body 110, and the micro control unit 130 is connected to the wearing detection module 120, and the micro control unit 130 is used to generate a wearing alarm signal according to the wearing signal; the alarm module 140 is fixedly arranged on the helmet body 110, and the alarm module 140 is connected to the micro control unit 130, and the alarm module 140 is used to generate an alarm prompt signal according to the wearing alarm signal.

[0029] Specifically, the helmet body 110 is used to fix and install different functional modules. The helmet body 110 can be one of a helmet shell, a hat lining, and a lower cheek strap, which can be selected according to different detection principles of the wearing detection module 120. It can be understood that the helmet body 110 can also be all the components that constitute the helmet, and the wearing detection module 120, the micro control unit 130 and the alarm module 140 can also be fixedly installed on different components of the helmet.

[0030] The wearing detection module 120 is fixedly arranged on the helmet body 110, and the wearing detection module 120 is used to generate a wearing signal according to the wearing action. The wearing signal is used to change with the wearing action of the operator, and the wearing signal of the operator under different wearing actions is also different. For example, the wearing signals generated by the wearing detection module 120 are all different when the operator does not wear, wears incorrectly, and wears the helmet correctly. The wearing detection module 120 can detect the wearing action of the operator in a variety of ways, for example, by detecting infrared rays of the human body, the pressure between the human body and the helmet, or the closed state of the buckle, to detect the wearing state of the helmet.

[0031] The micro control unit 130 is also fixedly arranged on the helmet body 110 and is in communication connection with the wearing detection module 120. When the wearing detection module 120 generates a wearing signal, the wearing signal is sent to the micro control unit 130. After receiving the corresponding wearing signal, the micro control unit 130 processes the wearing signal through a built-in program to obtain the wearing action of the operator wearing the helmet, and generates a corresponding wearing alarm signal when the wearing action does not meet the safety requirements.

[0032] The alarm module 140 is also fixedly arranged on the helmet body 110. The alarm module 140 is connected to the micro control unit 130 for communication and is used to receive a wearing alarm signal. When the alarm module 140 receives the wearing alarm signal, it will generate a corresponding sound and light type alarm prompt signal to remind the operator that the helmet is not currently worn or is worn incorrectly, so as to urge the operator to wear the helmet correctly to reduce safety hazards. It is understandable that in order to prevent the helmet from giving an erroneous alarm prompt signal when the operator has not entered the working state, a state switching switch can be set on the helmet or a near field communication method can be used to control whether the helmet enters the working state.

[0033] In one embodiment, as shown in FIG2 , the wearing detection module 120 includes: a pressure sensor 121, the pressure sensor 121 is connected to the micro control unit 130, and the pressure sensor 121 is used to generate a wearing signal according to the wearing action. Specifically, in the embodiment of the present application, the wearing action is detected by the pressure sensor 121, and the pressure sensor 121 can be set in the middle position of the cap lining, and is used to contact the top of the operator's head, so as to detect the pressure value between the safety helmet and the operator's head. When the operator wears it correctly, the pressure value is greater than the preset pressure value; when the operator does not wear it correctly or does not wear it, the pressure value will be less than the preset pressure value or even zero. By setting the pressure sensor 121, the action of the operator not wearing it correctly or not wearing it can be accurately detected, so that the operator can be warned through the alarm module 140, reminding the operator to wear a safety helmet, thereby reducing safety hazards.

[0034] In one embodiment, as shown in FIG2 , the smart helmet further includes: a height sensor 122, the height sensor 122 is connected to the micro control unit 130, the height sensor 122 is used to detect height information, the micro control unit 130 is used to generate a height warning signal according to the height information, and the alarm module 140 is used to generate a height prompt signal according to the height warning signal. Specifically, the height sensor 122 can be a barometric altitude sensor 122, the barometric altitude sensor 122 can detect the altitude, and the micro control unit 130 can generate a height warning signal when the altitude changes by 5 meters after obtaining the altitude information, and the alarm module 140 will generate a height prompt signal after receiving the corresponding altitude warning signal to remind the operator of the current altitude change. It is understandable that the micro control unit 130 can calculate according to the altitude on the ground and the altitude during operation, so as to obtain the height of the operator wearing the helmet from the ground. The operator can make the alarm module 140 display or voice broadcast the current height from the ground through the corresponding operation button, so that the operator can complete the query of the height from the ground.

[0035] In one embodiment, as shown in FIG2 , the smart helmet further includes: an electric field strength sensor 123, the electric field strength sensor 123 is connected to the micro control unit 130, the electric field strength sensor 123 is used to detect electric field strength information, the micro control unit 130 is used to generate an electric field strength alarm signal according to the electric field strength information, and the alarm module 140 is used to generate an electric field strength prompt signal according to the electric field strength alarm signal. Specifically, the electric field strength sensor 123 is used to receive signals in the power frequency electric field and measure the electric field strength. The electric field strength sensor 123 detects the electric field strength at the current position in real time, thereby obtaining the electric field strength information. After the micro control unit 130 receives the electric field strength information, it compares the detected electric field strength value with the preset strength value, and generates an electric field strength alarm signal when the electric field strength value is greater than the preset strength value. After the alarm module 140 receives the electric field strength alarm signal, it generates an electric field strength prompt signal (such as an indicator light or a voice broadcast) to prompt the operator that the operator is currently close to the charged object, reminding the operator to work carefully, thereby reducing safety hazards.

[0036] In one embodiment, as shown in FIG2 , the smart helmet further includes: an acceleration sensor 124, the acceleration sensor 124 is connected to the micro control unit 130, the acceleration sensor 124 is used to detect acceleration information, the micro control unit 130 is used to generate a behavior warning signal according to the acceleration information, and the alarm module 140 is used to generate a behavior prompt signal according to the behavior warning signal. Specifically, the acceleration sensor 124 of the embodiment of the present application can detect the acceleration information of the three-axis acceleration value of the helmet, and after the micro control unit 130 receives the corresponding acceleration information, it identifies static, moving, collision, falling and other behaviors according to different algorithms based on the built-in human motion acceleration characteristics. When the micro control unit 130 detects abnormal behavior, it will generate behavior warning information, and after the alarm module 140 receives the behavior warning information, it will generate a behavior prompt signal. For example, when an operator suddenly falls down after wearing a helmet, and after a long time, the operator still does not change his posture, at this time, the alarm module 140 can continuously send an alarm sound to prompt other nearby operators to check. It is understandable that when the alarm module 140 generates a false alarm, the operator can turn off the alarm module 140 through a set control button.

[0037] In one embodiment, the microcontroller unit 130 is a reduced instruction set computer processor. Specifically, the microcontroller unit 130 in the embodiment of the present application is a reduced instruction set computer (RISC) processor. RISC uses the most commonly used 20% simple instructions, and all instructions are of the same length, usually 4 bytes, and the positions of each field of the instruction are fixed to reduce decoding complexity. The other 80% of complex instructions are implemented by combining these simple instructions, thereby simplifying the internal circuit of the processor, facilitating the design of the processor, reserving more space for registers and caches, and improving processor performance. Preferably, RISC-V can be used. RISC-V is an open source instruction set structure of the fifth generation RISC, which has the advantages of modularity, low power consumption, high performance, and easy expansion. It can be freely used for any purpose, allowing anyone to design, manufacture and sell RISC-V chips and software. RISC-V includes the basic integer instruction set RV32I and multiple extended instruction sets M / A / F / D / C. Through the combination and extension of different instruction subsets, processors suitable for any field can be built. For example, in the embedded field, RV32I and C extended instruction sets can be selected to use machine mode to achieve low power consumption. In addition, RISC-V reserves opcode space to allow custom instructions to meet customization and specialization needs.

[0038] In one embodiment, as shown in FIG3 , the alarm module 140 includes an LED lamp 141 and / or a buzzer 142, and the LED lamp 141 and / or the buzzer 142 are used to emit light and / or buzz according to the wearing alarm signal. Specifically, the embodiment of the present application can send out corresponding prompt signals through the LED lamp 141 and / or the buzzer 142 to remind the operator. For example, when the alarm module 140 is only set to the LED lamp 141, multiple LED lamps 141 can be set, and the LED lamps 141 at different positions emit light, which means that the corresponding prompt information (such as wearing alarm, height alarm and electric field strength alarm, etc.) is issued. When the buzzer 142 is set, the voice information can be directly broadcast to notify the operator of the current alarm information type.

[0039] In one embodiment, as shown in Figure 3, the smart helmet also includes: a wireless communication module 150, the wireless communication module 150 is connected to the micro control unit 130, and the wireless communication module 150 is used to send a wearing alarm signal to the management background. Specifically, by setting the wireless communication module 150, the helmet can send some of the information it detects to the management background wirelessly. In the embodiment of the present application, the wearing alarm signal can be sent to the management background through the wireless communication module 150 to assist the management background in monitoring the wearing condition of the helmet. It is understandable that in some other embodiments, the micro control unit 130 can also send height alarm signals, electric field strength alarm signals, and behavior alarm signals to the management background through the wireless communication module 150.

[0040] In one embodiment, the wireless communication module 150 includes wireless communication chips of two network standards, NB-loT and GSM. Specifically, the model of the wireless communication chip can be the Internet of Things dual-mode module M5313. M5313 is a NB-IoT / GSM dual-mode industrial-grade wireless communication module that supports both NB-loT and GSM network modes. Using LCC (Leadless ChipCarriers) packaging, the module can be quickly produced through standard SMT (Surface Mounted Technology) equipment, providing a reliable connection method and meeting application requirements in harsh environments. At the same time, M5313 provides a wealth of external interfaces and protocol stacks, which provides great convenience for user product development.

[0041] In one embodiment, as shown in FIG3 , the smart helmet further includes: an audio and video acquisition module 160, the audio and video acquisition module 160 is connected to the micro control unit 130, the audio and video acquisition module 160 is used to collect audio and video information, and the micro control unit 130 is used to send the audio and video information to the management background through the wireless communication module 150. Specifically, by setting the audio and video acquisition module 160 on the helmet, the audio and video information in the working environment can be collected. After the micro control unit 130 sends the audio and video information to the management background through the wireless communication module 150, the management background can easily access the audio and video information of the working site and obtain the task progress in time. At the same time, the management background can also realize remote supervision and technical assistance to help safety supervisors to control the operation risks and reduce the potential safety hazards during operation.
