[0060] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, in the high-definition operation mode, the audio call module, the information transmission module and the main control module are all put into operation, the video module works in a high-definition acquisition mode, and the safety redundancy module works at a high-frequency acquisition speed. Further, in the high-definition operation mode, the main camera 31 and the auxiliary camera 32 both transmit the collected image data in 4K, and the video module is equipped with a three-axis self-stabilizing gimbal to work in a tracking mode, each sensor unit in the safety redundancy module uses a high-frequency acquisition speed, and other modules work normally.

[0061] In the normal operation mode, the audio call module, the information transmission module and the main control module are all put into operation, the video module works in a normal acquisition mode, and the safety redundancy module works at a medium frequency acquisition speed. Furthermore, in the normal operation mode, the main camera 31 and the auxiliary camera 32 both use 1080p streaming, the various sensor units in the safety redundancy module use medium and low frequency acquisition, and other modules work normally.

[0062] In the energy-saving operation mode, only the audio call module, the information transmission module, the safety redundancy module and the main control module are kept in operation. Furthermore, in the energy-saving operation mode, only the ZigBee unit, the audio call module, the safety redundancy module and the main control module in the information transmission module are guaranteed to work normally, and other modules are turned off. In this mode, only low-power data transmission of calls and voices and monitoring of safety conditions are guaranteed, which can ensure that the battery power can bear the system operation to the maximum extent, and ensure basic call operation and safety monitoring of the wearer.

[0063] In the sleep mode, only the main control module is kept in operation.

[0064] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the smart helmet also includes a chin strap 21 connected to the cap lining 2, and the cap shell 1 is made of one-piece molded ABS engineering plastic. Its appearance design is beautiful, sturdy and ergonomic.

[0065] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the video module, audio call module, safety redundancy module, information transmission module and main control module are connected by FPC flexible cable. At the same time, the smart helmet adopts a waterproof design, and the external interface, external connector, external opening, modules, structural parts and other fasteners are all arranged with waterproof design. Figure 4 Taking the waterproof structure of the external connector as an example, the external connector 41 is arranged on the cap shell 1, and the skirt of the rubber plug 42 is interference fit with the cap shell 1 and combined with the glue reinforcement treatment to achieve the expected waterproof effect.

[0066] The external openings mainly include the ventilation hole on the top of the cap shell, the sound receiving hole of the directional microphone pickup, the earphone opening and the speaker opening. Figure 5 Taking the speaker opening 51 as an example, the waterproof structure of the external opening includes the speaker opening 51 opened on the cap shell 1, a waterproof breathable membrane 53 is provided between the speaker 52 and the speaker opening 51, and a pressure plate 54 is provided on the side of the speaker 52 facing away from the speaker opening 51, and the pressure plate 54 applies a force toward the speaker opening 51 to the speaker 52 and the waterproof breathable membrane 53, so that the speaker opening 51 and the waterproof breathable membrane 53 fit tightly. The waterproof breathable membrane can be an IP67 waterproof breathable membrane. The waterproof structure ensures that the external opening is waterproof while ensuring the normal propagation of sound and air. In addition, for different external openings, a waterproof breathable membrane of a corresponding shape can be customized based on the shape and size of the device, and a special structure can be designed, and waterproof double-sided tape, waterproof sealant, etc. can be used to achieve better waterproof and breathable functions.

[0067] The waterproof design of various electronic components, structural parts and fasteners mainly consists of the following targeted designs: 1) For printed circuit boards and components, except for rotatable components, all are sprayed with TS01-3 polyurethane varnish triple-proof paint; 2) For structural parts, aluminum alloy structural parts are anodized after processing, and stainless steel materials are surface sprayed or baked blue; 3) For fasteners, stainless steel materials are used and fastened with oxygen-resistant glue; 4) In terms of cap shell sealing, a silicone rubber sealing ring that is resistant to salt spray and mildew is used to ensure airtightness; 5) For internal wires, wires with outer sheaths and mildew-proof functions are used.

[0068] Further, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the video module includes: a main camera 31, an auxiliary camera 32, a high-speed analog switch and a video processing chip. The image output end of the main camera 31 is connected to the first input end of the high-speed analog switch, the image output end of the auxiliary camera 32 is connected to the second input end of the high-speed analog switch, the output end of the high-speed analog switch is connected to the input end of the video processing chip, and the output end of the video processing chip is connected to the main control module. The main camera 31 is used to collect the main field of view image data of the smart helmet. The auxiliary camera 32 is used to collect auxiliary image data of the smart helmet. The main camera 31 and the auxiliary camera 32 are fixed to the helmet shell 1 through the front cover plate 33 of the helmet.

[0069] In the high-definition operation mode, the main camera and the auxiliary camera use 4K resolution to collect and transmit field of view image data; in the normal operation mode, the main camera and the auxiliary camera both use 1080p resolution to collect and transmit field of view images.

[0070] In some embodiments, the main field of view image data is image data in the main field of view of the wearer, and the image content changes with the movement of the wearer's head. For example, the main camera 31 can select a 4K starlight dark light main camera, such as a high-performance CMOS image sensor of model IMX415 4K, and install it in front of the helmet, flush with the wearer's field of view. The auxiliary camera 32 can select a wide-angle lens or an ultra-wide-angle lens, such as an image sensor chip of model GC2053. The main field of view image data can be image data within a range of 120° directly in front of the wearer's field of view, and the auxiliary image data can be image data of the wearer's surrounding environment. The above-mentioned main field of view image data and auxiliary image data include at least one of pictures, videos and live photos.

[0071] The 5G smart helmet for nuclear power industry inspection in this embodiment supports the simultaneous transmission of dual-channel images. Although the Hi3559V200 chip supports dual-channel camera input, its MIPI channel connecting the camera sensor and the processor is only 4 channels, and a single IMX415 image sensor already occupies 4 input channels. According to conventional processing, the system cannot support the input of dual-channel video signals. Therefore, the dual-channel video acquisition solution in this embodiment adopts a high-speed analog switch, preferably a high-speed analog switch of model FSA642, which uses its fast switching speed to realize cyclic switching between dual-channel camera signals, and quickly reads the exposure images of dual-channel sensors in a cycle, so that this smart helmet realizes the simultaneous acquisition of dual-channel videos and has transmission capabilities. When this solution transmits video on both channels at the same time, the theoretical frame rate of a single-channel image can reach 15 frames.

[0072] After actually collecting and analyzing the actual audio data at the industrial plant inspection site, it was found that the effect of using only software noise reduction solutions is limited. The traditional omnidirectional microphone reception will result in the collection of all background sounds. In order to cope with the noisy use environment, at the sound input level, the directional microphone pickup is pulled to the mouth in a pullable manner, and a windproof sheath is used to protect the directional microphone to prevent the influence of random wind noise on the call during speaking. The use of a directional microphone pickup can amplify the effective sound several times, and the environmental noise is relatively reduced due to reasons such as orientation and attenuation. The signal-to-noise ratio is improved through the structural design of the audio microphone, which effectively improves the noise reduction effect of the 5G smart safety helmet audio call module for nuclear power industry inspection in this embodiment.

[0073] In terms of sound output, traditional walkie-talkies have poor stability. If passive noise reduction equipment is mainly used, the noise reduction effect is limited and it is relatively heavy, which has a great impact on people's hearing. If the wearer is to be able to clearly communicate with external terminals or external platforms, active noise reduction can better protect people's hearing health while keeping the equipment light and reliable.

[0074] Furthermore, in the 5G smart safety helmet for nuclear power industry inspection disclosed in this embodiment, the audio call module includes: a directional microphone pickup, an active noise reduction headset 35, an active noise reduction chip and a voice processing chip. The output end of the directional microphone pickup is connected to the input end of the voice processing chip, and the output end of the voice processing chip is connected to the main control module; the input end of the active noise reduction headset 35 is connected to the output end of the active noise reduction chip, and the input end of the active noise reduction chip is connected to the main control module. The directional microphone pickup is used to transmit the first voice data to the voice processing chip, and the voice processing chip is used to transmit the first voice data to the main control module after processing. The active noise reduction chip is used to obtain and process the second voice data from the main control module, and the active noise reduction headset 35 is used to receive and play the second voice data from the active noise reduction chip.

[0075] Among them, the active noise reduction headphones 35 can be in-ear active noise reduction headphones, the active noise reduction chip model can be the Hengxuan 2300Z noise reduction chip, and the voice processing chip model can be the Hi3559V200 chip.

[0076] The working process of the audio call module is as follows: when working, the person wearing the helmet of the control layer equipment pulls the directional microphone pickup, and the directional microphone pickup recognizes the voice of the wearer. After the first voice data is collected, it is input into the voice processing chip through the headphone interface. After being processed by the noise reduction algorithm in the voice processing chip, the processed first voice data is sent to the back end. In some embodiments, the processed first voice data can also be encoded together with the field of view image video data of the video module and sent to the back end through the communication interface. After the voice information of the back end is received by the main control, it is directly sent to the audio processing chip Hengxuan 2300Z of the active noise reduction headset 35 through the headphone interface. The audio processing chip executes the active noise reduction algorithm, performs environmental noise analysis, and then outputs audio data with a 180-degree phase opposite to offset the environmental noise. The second voice data after active noise reduction enters the in-ear noise reduction headset again, so that the wearer can directly listen to the voice information without being disturbed by the external environment.

[0077] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the safety redundancy module includes: a gas sensor unit, a temperature sensor unit, a humidity sensor unit, a near-electric sensor unit and a posture sensor unit. The safety index data includes gas index data, temperature index data, humidity index data, near-electric sensor data and real-time posture data; the main control module is also used to: receive the real-time posture data and determine whether the update time of the real-time posture data exceeds the preset time. If so, control the intelligent system to enter the sleep mode.

[0078] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the main control module is also used to: receive the real-time posture data, analyze the real-time posture data, determine whether the wearer has a fall event and / or a collision event, and if so, issue a posture safety alarm. The posture sensing unit can be a gyroscope, preferably a three-axis gyroscope. In addition, the event information and alarm information of the fall and / or collision event are sent to the information transmission module, and then sent to the external terminal and / or external platform through the information transmission module.

[0079] Furthermore, in the 5G smart safety helmet for nuclear power industry inspection disclosed in this embodiment, the gas sensor can adopt a high-precision body sensor. The high-precision gas sensor can output the gas concentration value, and then output the relevant gas alarm information to the main control module according to the preset threshold and alarm: When the CO (carbon monoxide) concentration > the set value, it is regarded as carbon monoxide exceeding the standard. When the C2H5OH (ethanol) concentration > the set value, it is regarded as ethanol exceeding the standard. When the H2 (hydrogen) concentration > the set value, it is regarded as hydrogen exceeding the standard. When the NH3 (ammonia) concentration > the set value, it is regarded as ammonia exceeding the standard. When the CH4 (methane) concentration > the set value, it is regarded as methane exceeding the standard.

[0080] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the temperature sensor may be a high-precision temperature sensor, and the humidity sensor may be a dedicated humidity sensor. The high-precision temperature sensor in the barometer can detect temperature changes within 0.1 degrees. A dedicated humidity sensor can detect 1% RH humidity changes. When the ambient temperature is higher than the set value, it is considered a high temperature abnormality; when the ambient temperature change rate is higher than the set value, it is considered a temperature mutation abnormality. When the ambient humidity is higher than the set value, it is considered a high temperature abnormality; when the ambient humidity change rate is higher than the set value, it is considered a humidity mutation abnormality.

[0081] Furthermore, in the 5G smart safety helmet for nuclear power industry inspection disclosed in this embodiment, the near-electricity sensing unit is used to analyze and process the received monitoring signal and then extract the 50HZ industrial frequency signal, eliminate the interference signal through digital filtering, analyze its signal strength, and send a wireless alarm signal to the receiving end when the preset value is reached. The receiving end will alarm after receiving the signal, prompting the wearer to be close to strong electricity and pay attention to the danger. The near-electricity induction alarm can provide early warning for voltages above 220V with an industrial frequency of 50HZ-60HZ, and achieve anti-interference through digital filtering, which is stable and reliable. The method of prompting the user can be to send a near-electricity signal to the main control module, and the main control module controls the audio call module or the speaker to send a voice alarm message, or the main control module controls the indicator light to light up, or the main control module controls the vibrator to vibrate.

[0082] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the information transmission module includes: a wireless network communication unit, a short-range wireless communication unit and a navigation and positioning unit. The main control module is also used to: receive positioning information from the navigation and positioning unit, and determine whether the wearer is located in an indoor space or an outdoor space according to the positioning information. If the wearer is determined to be located in an indoor space, the short-range wireless communication unit is controlled to work; if the wearer is determined to be located in an outdoor space, the short-range wireless communication unit is controlled to sleep.

[0083] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the wireless network communication unit includes a 5G communication unit and / or a WiFi communication unit; the short-range wireless communication unit includes a Bluetooth communication unit and / or a ZigBee communication unit; the navigation and positioning unit includes a GPS unit and / or a BDS unit. The main control module is also used to: determine whether the communication speed of the 5G communication unit and the WiFi communication unit meets the preset requirements, if not, control the main camera and the auxiliary camera to reduce the acquisition clarity and transmission speed of the field of view image data; in the energy-saving operation mode, only the audio call module, the main control module, the safety redundancy module and the ZigBee communication unit are kept in operation.

[0084] The 5G communication unit can use the 5G module model FG132. The 5G network has the characteristics of wide connection and high speed, which can realize the networking and high-speed transmission of large-scale monitoring IoT terminals in industrial production scenarios such as industrial inspections, and complete the synchronous acquisition of multi-channel high-definition video and other information of wearable devices of large-scale operators, ensuring the collaborative operation of large-scale operators. The smart helmet equipped with this 5G module can realize fast data transmission including video, audio, positioning and various sensor information.

[0085] The WiFi communication unit and the Bluetooth communication unit can be integrated with the chip model Hi3861LV100, which integrates 2.4G WiFi and Bluetooth functions, and can communicate with the local area network via WiFi, and can also achieve information synchronization and transmission of multiple videos and multiple sensors. The Hi3861LV100 chip can also connect to other external devices or host computers via Bluetooth for data transmission and control, and is mainly used as an APP configuration and indoor beacon.

[0086] ZigBee can use the CC2530 module, which integrates an 8051 microcontroller and a wireless transceiver. The factory-installed firmware implements serial data transparent transmission based on the ZigBee protocol, and has functions such as role switching, automatic networking, network self-healing, and ultra-low power consumption. Under normal working conditions, this smart helmet can achieve low-power operation and improve battery life.

[0087] The electronic fence constructed by the GPS unit and / or the BDS unit is a technology of virtual area fence realized by GIS spatial algorithm. The GPS / BDS chip of the smart helmet sends the GPS positioning information of the device to the main control module through communication methods such as 5G and / or WiFi to complete the positioning of the smart helmet. The background system of the external terminal and / or the external platform calibrates the map according to the GIS information and longitude and latitude coordinates set in advance. The wearer, manager or other user can plan a target area on the map through the background system, such as a circular area and a polygonal area, etc. The target area is the range of the wearer's activities. The background system sends the determined electronic fence information to the main control module of the intelligent system 3 of the smart helmet. The main control module then analyzes and informs the background system whether the smart helmet is within the target area based on the electronic fence information and the current positioning information collected by the navigation positioning unit. If not, an alarm can be further issued.

[0088] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the smart system 3 also includes an interaction module, which is connected to the main control module; the interaction module includes at least one of a speaker, an indicator light, a button 34 and a display screen. In some other embodiments, the interaction module also includes a vibrator.

[0089] Furthermore, in the 5G smart safety helmet for nuclear power industry inspection disclosed in this embodiment, the main control module is also used to control the intelligent system 3 to switch the operation mode; the operation modes include: high-definition operation mode, normal operation mode, energy-saving operation mode and sleep mode.

[0090] Furthermore, in the 5G smart safety helmet for nuclear power industry inspection disclosed in this embodiment, it also includes a micro switch arranged on the inner side of the helmet shell 1 or the inner side of the hat lining 2; the main control module is also used to: determine whether the micro switch is triggered, and if not, control the intelligent system 3 to switch to the sleep mode.

[0091] Furthermore, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the operation mode also includes an intelligent operation mode. The intelligent operation mode focuses on strategic energy consumption control, and completes the energy-saving design from the optimal configuration that meets the functions. In the intelligent operation mode, the three-axis mechanical gimbal configured in the video module is not started under normal circumstances. After the operation is started, the follow mode is adopted by default and works in the general way of jitter suppression. Only when the camera is shooting in high definition is the full-scale anti-shake operation performed. When the power is turned on but the micro switch does not detect the wearing condition, the sleep low-power operation is adopted. At this time, all functions of the system are turned off, and only the main control module is guaranteed to continuously monitor the serial port and switch quantity data in the ultra-low sleep state to achieve the effect of sleep power saving. In addition, in the intelligent operation mode, when the video module transmits images with an external terminal or external platform, the WiFi communication unit is enabled first, followed by the 5G communication unit; when the video is not turned on, the ZigBee communication unit is used first, followed by the Bluetooth communication unit; the image data is transmitted in a high compression ratio by default; when operating outdoors, the Bluetooth communication unit is automatically turned off, and when operating indoors, the navigation and positioning unit automatically goes to sleep.

[0092] Furthermore, in the 5G smart safety helmet for nuclear power industry inspection disclosed in this embodiment, the intelligent system 3 also includes a power supply module, which is respectively connected to the video module, the audio call module, the information transmission module, the safety redundancy module and the main control module; the power supply module is used to provide power for the intelligent system 3; the main control module is also used to control the intelligent system 3 to run the energy-saving mode when it is detected that the power supply module is insufficient.

[0093] Further, in the 5G smart helmet for nuclear power industry inspection disclosed in this embodiment, the safety redundancy module also includes a power monitoring unit for monitoring the power supply module and performing an accident alarm when the power supply module fails. The power monitoring unit provides a related power accident alarm function, which acts on the power supply module, and the main control module obtains relevant information and executes the relevant judgment process. First, the power monitoring unit in the main control module continuously monitors the power supply output voltage and power status. When the voltage exceeds the safe range or the power supply power continues to decrease during the power charging and discharging process, the power monitoring unit detects and transmits the power data at this time to the main control module. The main control module performs power supply power analysis and power supply safety analysis based on the power management data, and an alarm is issued if the preset value is reached. The alarm information is sent to the communication unit through the main control module and then outputs the alarm with the external terminal and / or external platform, and at the same time starts the local process to alarm the helmet wearer through power off, vibration prompts, etc.

[0094] Furthermore, the intelligent system 3 adopts RBAC to manage user rights. Users are associated with rights through roles, thereby obtaining the right to use certain functions. Rights are granted to roles, not users, but a user can have several roles. When a role is granted to a user, the user has the functional rights contained in the role. Simply put, a user has several roles, and each role has several functional rights. In this way, an authorization model of "user-role-rights" is constructed. In this model, there is generally a many-to-many relationship between users and roles, and between roles and rights.
