Detailed implementation manners

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in detail with reference to specific embodiments and the accompanying drawings.

[0021] With the continuous development of mineral resource exploitation in China, the safety issues of open-pit and underground mining operation environments have received increasing attention.

[0022] Working in a high-temperature and high-humidity mine, the harsh environment will directly lead to the suppression of the workers' nervous system, and the judgment, memory and response ability of the surrounding emergencies will decrease accordingly. In addition, irritability and depression can easily lead to safety accidents. At the same time, when mining in deep wells, the mining depth is very dangerous, and there may be hazards such as roof collapse, gas accumulation, and water gushing at any time. In addition, in a high-temperature and high-humidity environment, the equipment will generate heat during operation, and the high-temperature heat accumulation will cause the plastic insulation of the machine to heat up easily, which is prone to fire. Working in a high-temperature and high-humidity working environment not only affects production efficiency and safe production, but also reduces the physiological, psychological and behavioral abilities of the human body, resulting in reactions such as drowsiness, fever, water and salt metabolism disorders, skin diseases, internal circulation system disorders, and mental depression. The longer the working time, the greater the harm to the human body. The dysfunction of the body's temperature regulation function for heat production and heat dissipation may destroy the body's thermal balance, causing heat stroke, heat cramps, heat exhaustion, and in severe cases, shock, and even death.

[0023] High temperature and high humidity also have an impact on mining efficiency. On the one hand, workers cannot work in this environment for a long time at a high intensity, especially front-line production workers are prone to various diseases, which reduces attendance and affects production; on the other hand, in a hot and humid environment, workers sweat profusely, feel hot and uncomfortable, and are irritable. In addition, underground mechanical equipment has difficulty in operating and dissipating heat, and the machines are prone to aging and damage, resulting in reduced production efficiency.

[0024] In addition to working in the mine, workers not only have to face high temperature and high humidity, but are also prone to potential landslides, rock bursts and other problems. When workers are hit by rocks, roofs, or accidentally hit by other equipment, fall down, etc., due to the suddenness of the incident, they usually have little time and energy to call for help. Even if they call for help, it is difficult to attract the attention of others due to the noisy working environment underground, which poses a serious threat to the safety of the workers.

[0025] In the prior art, in order to protect the safety of workers, mining protective equipment has been developed. However, mining protective equipment is inconvenient to wear and has a single function, which makes it difficult to meet the protection safety and comfort requirements in complex mine environments, especially in the lack of extrusion protection, emergency alarm and real-time monitoring. Therefore, it is necessary to develop a new type of integrated intelligent protective equipment that can provide comprehensive protection for the human body while having good flexibility and adaptability, meet the diverse needs of the mining operating environment, and provide efficient, portable and reliable mine work safety protection.

[0026] In view of this, the present application discloses a mining protective vest, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it integrates multiple functions, can detect environmental information in real time, can automatically give warnings according to environmental changes and automatically take certain measures to cool down the operators, improving operation safety and comfort. It includes: a vest body 1, an automatic control component 12, a sensor component, a positioning component and a cooling component arranged on the vest body 1; The automatic control component 12 is respectively connected to the sensor component, the positioning component and the cooling component; The sensor component is used to collect the temperature and humidity of the current environment in real time and the pressure borne by the vest body 1 currently, and transmit the detected current temperature data, current humidity data and current pressure data to the automatic control component 12; The positioning component is used to detect the current position information and send the detected current position information to the automatic control component 12; The automatic control component 12 is used to control the working state of the cooling component based on the received current temperature data and current humidity data, and calculate a comprehensive risk coefficient based on the received current temperature data, current humidity data and current pressure data; In response to the comprehensive risk coefficient exceeding the safety threshold, send an alarm and the current position information to an external monitoring platform.

[0027] In existing underground mine operations, although certain measures are taken to reduce the humidity and temperature in the mine, due to problems such as the large scope of the mine, complex underground environment, and high technical difficulty, it is still difficult to completely solve the problem of high-temperature and high-humidity operations. In this application, an automatic control component 12, a sensor component, a positioning component, and a cooling component are provided on the vest body 1. When an operator wears the protective vest for work, the sensor component on the vest body 1 can detect the temperature and humidity of the environment where the wearer is located in real time, and control the cooling component to turn on according to the humidity or temperature change to cool the wearer and prevent the operator from fainting or suffering heatstroke due to excessive humidity or temperature. At the same time, the sensor component can also detect the pressure currently borne by the vest body 1. When the wearer is hit or squeezed, the sensor component can detect the pressure change and transmit the data to the automatic control component 12. The automatic control component 12 combines the pressure change, temperature, and humidity change to calculate a comprehensive risk coefficient and issue an alarm according to the comprehensive risk coefficient. When the comprehensive risk coefficient is too high, it indicates that the current temperature or current humidity of the environment is not suitable for work, or the wearer has suffered a certain accident and needs to request external assistance. At this time, an alarm and the current location information are sent to the external monitoring platform to help the operator be rescued in time. In this application, not only can the temperature and humidity changes in the environment be monitored, the cooling component can be automatically controlled according to the temperature and humidity, but also whether the operator has an accident can be monitored. At the same time, it has a positioning function, with diverse functions, which can help the operator cool down in time and reduce the probability of accidents such as fainting and heatstroke; when the environment is not suitable for continued work or an accident occurs, it can call for help in time, ensuring the personal safety of the operator from multiple angles and effectively improving the work safety and comfort.

[0028] Optionally, the external monitoring platform can be a unified monitoring platform set up in the mine, such as a mine management system, or the mobile phones of managers, safety supervisors, etc., or an APP, etc. The specific sending method of the alarm information can be sending text messages, message reminders, making phone calls, etc., without specific restrictions.

[0029] The sensor component includes a temperature sensor 6, a humidity sensor 7, and a pressure sensor 8, which are respectively used to collect the temperature, humidity of the current environment, and the pressure currently borne by the vest body 1. The temperature sensor 6, the humidity sensor 7, and the pressure sensor 8 can be integrated in one device, or as Figure 1 、 Figure 3The ones shown are separately arranged on the vest body 1, and there is no specific limitation. The positioning component includes a Beidou positioning component 10 and a 5G positioning component 11. The Beidou positioning component 10 can track the position of workers in real time in a wide working area of the open-pit mine, and when working underground, the 5G positioning component 11 is used to position the person wearing the vest. The positioning component is connected to an external monitoring platform, and when an accident occurs to the person wearing the vest, the position of the worker can be quickly located and rescue can be carried out. The positioning component can also be used to record the movement path of the worker, provide work logs and safety analysis data, and help optimize the operation process and safety strategy. The sensor component and the positioning component adopt devices with waterproof, dustproof and anti-interference capabilities to ensure the accuracy and stability of data collection in the mine.

[0030] In some embodiments, the comprehensive risk coefficient is calculated by the following formula:

[0031] Wherein, , is the temperature risk coefficient, is the humidity risk coefficient, is the pressure risk coefficient, is the comprehensive risk coefficient, T is the current temperature data, H is the current humidity data, P is the current pressure data, is the safety temperature threshold, is the safety humidity threshold, is the safety pressure threshold.

[0032] When workers are working underground, they may not only be affected by high-temperature and high-humidity environments, but may also encounter accidental events such as cave-ins, buryings, and falls. Therefore, in order to monitor multiple safety influencing factors affecting mine workers at the same time, the above formula is designed to calculate the comprehensive risk coefficient, taking into account the current environmental temperature, the current environmental humidity and the pressure borne by the person wearing the vest, and comprehensively evaluating the safety of the person wearing the vest. Collect the current temperature data, the current humidity data and the current pressure data, calculate their ratios with the safety temperature threshold, the safety humidity threshold and the safety pressure threshold, determine the degree to which the current temperature, the current humidity and the current pressure exceed the safety temperature, the safety humidity and the safety pressure, and then determine the final comprehensive risk coefficient by integrating the risk coefficients of each influencing factor. The calculation process is scientific and efficient, can accurately balance the influence degrees of multiple factors on the safety of workers, timely discover potential safety crises, and provide effective guarantee for the safe operation of workers. Optionally, the safety temperature threshold can be set to 38 °C, or can be set to other temperatures, such as 37, 36, 35, 34, 33, 32, 31, 30 °C, etc., and there is no specific limitation; the safety humidity threshold It can be set to 65%, or other humidity values such as 75, 70, 60, 55, 50, 45%, etc., without specific limitation; the safety pressure threshold It can be set to 0.2 mPa for judging possible strong impacts, or other values without specific limitation.

[0033] In some embodiments, controlling the working state of the cooling component based on the received current temperature data and the current humidity data includes: Calculating a temperature control comprehensive coefficient based on the current temperature data and the current humidity data; In response to the current temperature data exceeding the safety temperature threshold or the current humidity data exceeding the safety humidity threshold or the temperature control comprehensive coefficient exceeding the comprehensive coefficient threshold, controlling the cooling component to turn on.

[0034] Both temperature and humidity will affect the operation comfort and safety of the staff. Therefore, when the ambient temperature is too high or the humidity is too high, controlling the cooling component to turn on to cool down the wearer can effectively improve the operation comfort and safety of the operators. However, the effects of temperature and humidity on the human perception are not independent, and there is a certain correlation between them. When both the temperature and humidity do not reach the safety threshold, looking at the temperature or humidity alone may be within the normal range, but when the two factors act together, it may make people feel uncomfortable, stuffy, short of breath, etc. Therefore, in this application, not only can the current temperature or the current humidity be used alone as one of the conditions for turning on the cooling component, but also the temperature control comprehensive coefficient can be calculated based on the current temperature and the current humidity to fully consider the combined effect of temperature and humidity on the human perception, and timely turn on the cooling component for the wearer to ensure the operation comfort and safety of the operators.

[0035] In some embodiments, controlling the cooling component to turn on includes: Determining the first working intensity of the operation of the cooling component based on the amplitude of the current temperature data exceeding the safety temperature threshold; Determining the second working intensity of the operation of the cooling component based on the amplitude of the current humidity data exceeding the safety humidity threshold; Determining the third working intensity of the operation of the cooling component based on the amplitude of the temperature control comprehensive coefficient exceeding the comprehensive coefficient threshold; Determining the maximum working intensity among the first working intensity, the second working intensity and the third working intensity as the target working intensity of the cooling component; Starting the cooling component based on the target working intensity; Wherein, the first working intensity is directly proportional to the amplitude by which the current temperature data exceeds the safety temperature threshold, the second working intensity is directly proportional to the amplitude by which the current humidity data exceeds the safety humidity threshold, and the third working intensity is directly proportional to the amplitude by which the temperature control comprehensive coefficient exceeds the comprehensive coefficient threshold.

[0036] In the actual application of a mine, in the face of different temperature and humidity environments, the cooling intensity required by the human body is different. For example, when both the temperature and humidity are relatively high, the cooling component needs to operate at a higher intensity at this time to help the operators cool down better. Therefore, the higher the current temperature data, the current humidity data, and the temperature control comprehensive coefficient, the higher the working intensity of the corresponding cooling component. Specifically, when the sensor component detects that the current temperature data exceeds the safe temperature threshold, determine the amplitude by which the current temperature data exceeds the safe temperature threshold, and determine the first working intensity according to this amplitude; when the sensor component detects that the current humidity data exceeds the safe humidity threshold, determine the amplitude by which the current humidity data exceeds the safe humidity threshold, and determine the second working intensity according to this amplitude; when the sensor component detects that the temperature control comprehensive coefficient exceeds the comprehensive coefficient threshold, determine the amplitude by which the temperature control comprehensive coefficient exceeds the comprehensive coefficient threshold, and determine the third working intensity according to this amplitude; then determine the maximum working intensity among the first working intensity, the second working intensity, and the third working intensity as the target working intensity of the cooling component, and then start the cooling component with the target working intensity. When only the current temperature data exceeds the safe temperature threshold, the cooling component can be directly started with the determined first working intensity; when only the current humidity data exceeds the safe humidity threshold, the cooling component can be directly started with the determined second working intensity; when only the temperature control comprehensive coefficient exceeds the comprehensive coefficient threshold, the cooling component can be directly started with the determined third working intensity. The greater the amplitude by which the first working intensity exceeds the current temperature data, the higher the first working intensity. Similarly, the higher the amplitude by which the current humidity data exceeds the safe humidity threshold and the higher the amplitude by which the temperature control comprehensive coefficient exceeds the comprehensive coefficient threshold, the higher the corresponding second working intensity and third working intensity. Thus, when the environment is harsher and stuffier, the working intensity of the cooling component is greater, which better helps the operators cool down. Optionally, the cooling component includes a cooling fan and / or an ice pack, and the ice pack is a temperature-adjustable ice cooling device. The cooling fan and the ice pack can be set to have at least two working modes, and the working intensities corresponding to different working modes are different. For example, there are working modes of first gear, second gear, and third gear. The running speed of the cooling fan corresponding to the first gear, second gear, and third gear gradually increases, and the lower the set temperature of the ice pack, the gradually increasing the cooling effect. The cooling fan or the ice pack can be controlled to be turned on separately, or the cooling fan and the ice pack can be controlled to be turned on simultaneously to help the operators cool down, and there is no specific limitation. In addition, the running speed of the cooling fan can also be determined by the amplitude by which the current temperature data exceeds the safe temperature threshold, or the amplitude by which the current humidity data exceeds the safe humidity threshold, or the amplitude by which the temperature control comprehensive coefficient exceeds the comprehensive coefficient threshold.

[0037] Exemplarily, taking the determination of the speed of the cooling fan by the amplitude by which the current temperature data exceeds the safe temperature threshold as an example, the running speed of the cooling fan (i.e., the first working intensity) can be determined by the following formula:

[0038]

[0039] Among them, is the amplitude by which the previous temperature data exceeds the safety temperature threshold, is the minimum speed of the fan, is the first working intensity, is the wind speed adjustment proportionality coefficient. When only the current temperature data exceeds the safety temperature threshold, the first working intensity is the target working intensity to start the cooling component.

[0040] In some embodiments, starting the cooling component based on the target working intensity includes: Determining the working acceleration at which the cooling component operates according to the target working intensity; Controlling the cooling component to operate at the working acceleration until the target working intensity is reached.

[0041] Under normal circumstances, after determining the target working intensity of the cooling component, the cooling component is directly started at the maximum power so that the cooling component can run to the target working intensity as soon as possible. However, when operating underground in a mine, if the cooling component is started too quickly or with too high an intensity, the cold stimulus to the human body is too fast, which easily makes the staff feel an obvious temperature difference, thus causing physical discomfort, and even situations such as catching a cold or getting sick. Therefore, in this application, after determining the target working intensity, the working acceleration is determined according to the target working intensity, and then the cooling component is controlled to run at this working acceleration to the target working intensity, controlling the speed of the cooling component from the start to the normal operation state (i.e., the state of continuously running at the target working intensity), thereby controlling the cooling rate and avoiding problems such as too fast cooling and too large instantaneous temperature difference that cause discomfort to the human body. Optionally, the working acceleration corresponding to the target working intensity can be the same or different, that is, the working acceleration increases with the increase of the target working intensity, and on the basis of ensuring the comfort of the human body feeling, the cooling speed is increased as much as possible.

[0042] In some embodiments, the temperature control comprehensive coefficient is calculated according to the following formula: ; where is the temperature control comprehensive coefficient, and the is the temperature weight coefficient, is the humidity weight coefficient; ; ; is the current temperature data, is the safety temperature threshold; is the current humidity data, is the safety humidity threshold.

[0043] In this application, the comprehensive temperature control coefficient is calculated by calculating the amplitudes by which the current temperature data exceeds the safe temperature threshold and the current humidity data exceeds the safe humidity threshold, which can fully consider the combined effects of temperature and humidity on the human body, thereby better controlling the operation of the cooling component, better cooling the operators, and ensuring the work efficiency and physical health of the operators. Optionally, the safe humidity threshold, the safe temperature threshold, and the comprehensive coefficient threshold are preset, or can be freely set by the staff according to their own sensitivity to temperature, and there is no specific limitation.

[0044] In some embodiments, it further includes an airbag assembly 18, and the airbag assembly 18 includes a first airbag 1802 and a second airbag 1801, and the first airbag 1802 and the second airbag 1801 are respectively arranged on the front chest part and the back part of the vest body 1; Wherein, the sensor assembly is further used to detect the acceleration of the vest wearer and transmit the current acceleration data to the automatic control assembly 12; The automatic control assembly 12 receives the current acceleration data, and in response to the current acceleration data exceeding the acceleration safety threshold or the current pressure data exceeding the safety pressure threshold, controls the airbag assembly 18 to be in an inflated state.

[0045] In this application, the first airbag 1802 is arranged on the front chest part of the vest body 1, and the second airbag 1801 is located on the back part of the vest body 1. It can be set that when the wearer encounters a collision or impact, the airbag assembly 18 automatically pops up and inflates to protect the vest wearer. In addition, the acceleration of the vest wearer and the pressure borne by the vest body 1 can also be detected by the sensor assembly to control the state of the airbag assembly 18. When an operator is about to fall accidentally, their acceleration will change significantly. Therefore, by detecting the change in their acceleration, it can be predicted whether the current operator has encountered an accident; when abnormal acceleration is detected, it means that the operator is starting to fall at this time, and at this time, the airbag assembly 18 is triggered to quickly pop up, covering important parts of the operator, such as the front chest, back, head, etc., to prevent the operator from directly hitting the ground and causing injury. When the pressure borne by the vest is abnormal, it means that the operator may have suffered external forces such as extrusion and collision at this time, and the airbag assembly 18 quickly pops up at this time to protect the vest wearer.

[0046] The airbag assembly 18 is mounted on the inner side of the vest body 1 through a protective mounting plate. There is a certain gap between the side of the protective mounting plate and the vest body 1. When the airbag assembly 18 is subjected to an impact or the current acceleration data exceeds the acceleration safety threshold, the airbag assembly 18 quickly inflates and expands out from the gap. The first airbag 1802 and the second airbag 1801 wrap around the human body to avoid the operator from being injured again after falling. Optionally, the airbag assembly 18 is further provided with a third airbag. The third airbag is connected and communicated with the second airbag 1801 and is arranged on the back part of the vest body 1 together with the second airbag 1801. When the acceleration data exceeds the acceleration safety threshold or the current pressure data exceeds the safety pressure threshold, the third airbag bulges out from the back of the neck of the vest body 1 and surrounds the head to protect the head of the operator. Optionally, the first airbag 1802, the second airbag 1801, and the third airbag can be communicated and integrally controlled by the automatic control component 12, or can be separately arranged, that is, the automatic control component 12 can separately control the first airbag 1802, the second airbag 1801, or the third airbag. When the human body falls backward, only the second airbag 1801 and the third airbag can be controlled to inflate. When the human body falls forward, only the first airbag 1802 can be controlled to inflate, realizing the precise control of the airbag, which can effectively improve the service life of the airbag. Optionally, the airbag assembly 18 is a reusable component, supporting the functions of automatic deflation and reset, capable of inflating and deflating multiple times, ensuring normal operation after multiple uses on the basis of maximizing the protection of the worker's physical safety, and improving the practicability and service life.

[0047] In some embodiments, the sensor assembly is further configured to detect the angle of the vest wearer and transmit the current angle data to the automatic control component 12; The automatic control component 12 receives the current angle data and controls the airbag assembly 18 to be in an inflated state in response to the current angle data exceeding the angle safety threshold.

[0048] When a person falls, the angle of the human body changes significantly. Therefore, it is also possible to determine whether to inflate the airbag assembly 18 by detecting the angle of the person wearing the vest. To better detect the state of the wearer, the current angle data and the current acceleration data can be used for joint prediction. That is, the airbag assembly 18 is only activated when both the current angle data and the current acceleration data exceed the safety threshold. Optionally, the sensor assembly includes a six-axis sensor 9, and the six-axis sensor 9 is used to detect the angle and acceleration of the person wearing the vest. The automatic control component 12 includes an STM32F103 microcontroller. The STM32F103 microcontroller is based on the ARM Cortex-M3 core and has excellent real-time performance and low-power characteristics. It performs real-time analysis on the data from the temperature sensor 6, the humidity sensor 7, the pressure sensor 8, and the six-axis sensor 9, has the ability of self-learning, can optimize the algorithm through historical data, and automatically adjusts the working modes of the cooling component and the airbag assembly 18 to provide more accurate personalized protection.

[0049] In some embodiments, it further includes an obstacle detector 16 and an alarm 2 provided on the vest body 1, and the obstacle detector 16 and the alarm 2 are connected to the automatic control component 12; In response to the obstacle detector 16 detecting an obstacle, the automatic control component 12 controls the alarm 2 to issue an alarm.

[0050] Specifically, the obstacle detector 16 can be arranged on the back of the vest body 1 to detect obstacles and dangerous objects (such as mining equipment, etc.) on the side and rear of the vest wearer. When an obstacle or dangerous object is detected, the alarm 2 is used to issue an alarm. The alarm 2 can specifically include an audible and visual alarm 20 and a vibration alarm 21, which remind the vest wearer and surrounding personnel by simultaneously emitting a reminder sound, reminder light, and vibration, thereby improving the safety of the operator during underground operations in the mine. Optionally, the obstacle detector 16 includes an NFC transceiver. When a worker approaches a dangerous device such as mining equipment, the NFC transceiver automatically sends a signal to the device. After the device receives the signal, the alarm 2 is triggered to emit a reminder sound, reminder light, and vibration. The sound and light can remind the device operator to promptly discover the vest wearer, and the vibration can remind the vest wearer that they are approaching the device and there is a certain danger, thus providing multiple protections for the personal safety of the vest wearer. Optionally, when the automatic control component 12 detects that the current temperature data exceeds the safety temperature threshold, or the current humidity data exceeds the safety humidity threshold, or the temperature control comprehensive coefficient exceeds the comprehensive coefficient threshold, or the current pressure data exceeds the safety pressure threshold, the automatic control component 12 controls the alarm 2 to issue an alarm to remind the operator to take timely measures. The NFC transceivers of multiple vest wearers can also be communicatively connected to each other to provide a collective early warning function, that is, when one vest wearer approaches a dangerous object or obstacle, nearby workers will also receive an alarm to ensure the safety of team cooperation.

[0051] In some embodiments, it further includes a voice collection component arranged on the vest body 1; The voice collection component is used to collect the voice of the user and send the collected voice to the automatic control component 12; The automatic control component 12 controls the cooling component or the positioning component to execute corresponding commands according to the received voice.

[0052] In this application, a voice collection component is also arranged on the vest body 1. Specifically, it can be arranged at the collar of the front placket 3 of the vest body 1 to facilitate the collection of voice commands of the vest wearer. When the vest wearer wants to turn on the cooling component or encounters discomfort and wants to call for help, they can issue a command through the voice collection component. After the automatic control component 12 receives the voice information, it analyzes the command to be executed and then operates the corresponding component to perform the corresponding operation to achieve voice control and voice help seeking.

[0053] In this application, the vest body 1 is made of carbon fiber composite material, which can be wear-resistant and high-temperature resistant, improving the service life of the vest and providing certain protection for the person wearing the vest. Optionally, the vest body 1 is filled with a polymer composite material. When the person wearing the vest is subjected to external force, the polymer composite material can absorb and disperse the external impact energy. The polymer composite material can be a foam polymer material, a carbon fiber reinforced resin matrix composite material (CFRP), etc. CFRP is prepared by curing, demolding and other processes for the resin matrix and carbon fiber in a high-temperature and high-pressure environment, and has the characteristics of light weight, high strength and strong designability. The specific strength (strength per unit weight) and specific modulus (stiffness per unit weight) of the CFRP material enable it to maintain good deformation and recovery ability under multiple impacts. It can effectively absorb and disperse energy when subjected to external impact, reducing the impact on the worker's body. The polymer composite material filled in the vest body 1 is detachable and replaceable to ensure the best energy absorption effect after multiple uses.

[0054] In some embodiments, in response to the position indicated by the current position information belonging to a preset dangerous area, the alarm 2 is controlled to issue an alarm. During mine operations, whether it is an open-pit stope or an underground stope, there may be some relatively dangerous areas, such as areas prone to collapse. When operating personnel are working, they are likely to accidentally enter these dangerous areas, posing a serious threat to their personal safety. Therefore, based on the current position information, it can be determined whether the position where the operating personnel are located is a preset dangerous area. If so, an alarm is issued through the alarm 2 to remind the person wearing the vest to stay away from this area; when the person wearing the vest has been in the dangerous area and has not left, an alarm and the current position information can be sent to an external monitoring platform so that the mine managers can discover this problem in time.

[0055] The vest body 1 includes a front flap 3 and a rear flap 15. The front flap 3 and the rear flap 15 are connected as a whole through the shoulders 5. The front flap 3 and the rear flap 15 are located at the position below the armholes and are connected by an adjustable buckle 4. The front flap 3 includes a left front flap 301 and a right front flap 30. The left front flap 301 and the right front flap 30 can be movably connected by a vertically arranged zipper or by a plurality of buckles, and no specific limitation is made. An installation buckle 13 is provided at the lower hem position of the left front flap 301, and an installation hole 14 corresponding to the installation buckle 13 is provided on the rear flap 15. The installation buckle 13 can be buckled into the installation hole 14 to further fix the lower part of the vest body 1.

[0056] The first airbag 1802 can be set to two, which are respectively located on the inner sides of the front chest parts of the left front flap 301 and the right front flap 30; the second airbag 1801 is arranged on the inner side of the back part of the back flap 15; the sensor assembly, the automatic control assembly 12, the positioning assembly, and the alarm 2 are arranged near the shoulders 5 of the front flap 3 for facilitating information collection; the obstacle detector 16 is arranged on the back flap 15 for detecting obstacles and dangerous objects on both sides and at the rear of the person wearing the vest. A switch button 17 is also arranged on the front flap 3, and the automatic control assembly 12, the sensor assembly, the positioning assembly, and the temperature reduction assembly can be controlled to be turned on and off through the switch button 17.

[0057] When an operator needs to wear the protective vest, adjust the shoulders 5 of the vest body 1 to ensure a comfortable fit on the shoulders of the wearer, and fix the vest body 1 through the adjustable buckles 4, the zipper, the mounting buckles 13, and the mounting holes 14. At this time, the protective vest is worn. Then turn on each component through the switch button 17 to ensure that each component is in a working state for automatically monitoring environmental temperature, humidity, pressure, etc.
