Description

Technical Field

[0001] The utility model belongs to the field of protective clothing and relates to an intelligent integrated multifunctional protective clothing. Background Art

[0002] In recent years, the safety of personnel in water-related operations such as offshore platforms, explosion-proof docks, and offshore drilling platforms has become increasingly prominent. In complex disaster scenarios at sea, operators and firefighters may face dangers such as explosions, fires, and falling into the water at the same time. Traditional life jackets are not fireproof, and fire suits have no buoyancy. There is a lack of protective clothing that is both fireproof and water-floating. This is a key factor that makes it difficult to ensure personnel protection after a dangerous situation occurs.

[0003] Chinese patent CN 220594298 U (application number 202321440097.9) discloses a floating fireproof hierarchical structure for shelter clothing, including a fire-retardant surface layer, a composite foam material core layer, and a comfortable lining layer. The composite foam material core layer is mainly a composite foam material composed of resin and filler, which undertakes the main buoyancy and heat insulation functions. Chinese patent CN 220360146 U (application number 202321285962.7) proposed by Ma Zhe and others from Dalian University of Technology proposed a nickel-plated magnetized hollow glass microsphere clothing armor sheet. By modifying the microspheres with nickel plating, the overall strength and heat insulation performance of the material are improved, and it is made into an armor sheet for use on shelter clothing. The above are all traditional protective clothing. In the context that a multifunctional protective clothing suitable for escape and rescue in sea-related explosions and fires has been developed, traditional protective clothing still has the following problems:

[0004] Traditional protective clothing mainly provides passive protection, such as heat insulation, heat resistance, and water buoyancy, but has limited capabilities in monitoring and warning the health status of firefighters and marine workers and determining their location information. After fire, explosion, drowning and other dangerous situations occur, traditional protective clothing cannot report the wearer's physical condition, such as heart rate, blood oxygen, body temperature, etc., to the command center and other relevant departments, which may lead to health risks not being identified and handled in time, and then leading to untimely rescue and increased casualties; relevant departments are also unable to obtain the wearer's location information, so that after the dangerous situation occurs, firefighters and marine workers are out of contact, which brings difficulties to rescue and reinforcement operations. Once they fall into the sea, the wearer's chance of survival will be slim.

[0005] In addition, traditional protective clothing cannot warn of potential dangers in a fire environment, such as smoke, harmful gases, and heat energy distribution. A fire scene is often filled with a large amount of smoke, carbon monoxide, nitrogen oxides and other harmful gases or particulate matter, some of which are even colorless and odorless. Once the content of these gases or particulate matter in the fire environment exceeds the standard, it will cause irreversible damage to the life and health of firefighters; the concentration of flammable and explosive gases such as natural gas and liquefied gas also indicates whether there will be a risk of secondary explosion; the fire in a fire environment changes in a complex manner, and the lack of heat energy distribution information in the fire scene will also make it difficult for firefighters to choose the correct rescue measures.

[0006] In the past two decades, extensive research has been conducted on intelligent protective clothing at home and abroad, but there are still problems such as single function, poor integration effect, and high cost of use. When protective clothing is integrated with traditional rigid sensors, if there are many types of integrated sensors, the wiring of electronic components such as sensors and microcontrollers will often be complicated and cumbersome, resulting in poor integration effect, which will have a great impact on the wearing comfort, convenience, and aesthetics of protective clothing; but if there are fewer types of integrated sensors, it will lead to a single function. The use of new flexible sensors and conductive yarns as conductors for the integration of protective clothing can effectively solve the problems of wearing comfort and convenience, but it will also lead to high manufacturing and use costs, which is not suitable for large-scale use. Utility Model Content

[0007] The utility model provides an intelligent integrated multifunctional protective clothing, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problem that traditional protective clothing cannot monitor the wearer's physiological condition, position information and has a weak ability to perceive the fire environment. By integrating the intelligent monitoring device with the protective clothing, the utility model can effectively monitor the wearer's heart rate, blood oxygen, body temperature, position information and other key parameters, as well as environmental conditions such as smoke concentration, harmful gas concentration, and heat energy distribution in the fire scene. The data can also be uploaded to the cloud management platform through the wireless communication module, which is conducive to peripheral monitoring and combat command. The utility model has the advantages of novel design, easy to wear, and full functions.

[0019] Layout location:

[0020] The protective clothing hierarchical structure is as described in patent CN 220594278 U. The protective clothing top includes a protective clothing outer layer 20, a protective clothing middle layer 21, and a protective clothing inner layer. The protective clothing outer layer 20 is a flame retardant and fireproof surface layer, the protective clothing middle layer 21 is a composite foam material core layer, and the protective clothing inner layer is a comfortable lining layer. The three layers are closely arranged and fitted. The specific materials used and the design method are basically the same as those described in patent CN220594278U of Dalian University of Technology Ma Zhe et al., a floating fireproof hierarchical structure for shelter clothing, which will not be repeated here. The differences are:

[0021] The solid material module of the middle layer 20 of the protective clothing is shown in patent CN 308242009 S. In order to solve the influence of the hard clothing body made of the composite foam material of the middle layer 20 on human activities, the core layer of the composite foam material is divided into many solid material modules according to the distribution of human muscles and the rotation range of joints.

[0022] The shell 21 is made of polyimide material with good high temperature resistance and heat insulation properties, and is sprayed with high temperature resistant paint, such as silicone, on the outer layer to improve the high temperature tolerance of the intelligent monitoring device. The shell 21 will replace the original solid material module near the left chest of the middle layer of the patent CN308242009 S protective clothing to achieve the integration of the intelligent monitoring device and the protective clothing.

[0023] The charging and discharging module 1 , the display module 3 , and the communication module 4 are integrated on a PCB board. The PCB board is placed in the housing 21 and fixed by a card slot provided inside the housing 21 .

[0024] The positioning module 17 , the infrared radiation heat sensor 13 , the smoke sensor 15 , and the carbon monoxide sensor 16 are all placed in the housing 21 and fixed by providing a card slot inside the housing 21 .

[0025] The sensing probes 22, 23 of the smoke sensor and the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor need to be in contact with the external environment. Therefore, during integration, a reserved opening will be set on the shell 21 according to the shape of the sensing probes 22, 23 and the temperature measuring probe 24; at the same time, a reserved opening will be set on the left chest part of the outer layer of the protective clothing according to the shape of the sensing probes 22, 23 of the smoke sensor, the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor, so that the sensing probes 22, 23 of the smoke sensor, the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor can fully contact with the environment to improve the measurement accuracy. The connection between the sensing probes 22, 23 of the smoke sensor, the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor and the reserved opening of the shell 21 and the outer layer of the protective clothing will be sealed with an adhesive to improve the waterproofness of the intelligent monitoring device.

[0026] The positioning module 17 includes a positioning unit and an antenna 25. The antenna 25 will pass through the reserved opening at the rear of the shell 21 to reach the left collar of the protective suit and be fixed to the collar of the protective suit using an adhesive. The connection between the antenna 25 and the reserved opening at the rear of the shell 21 is sealed with an adhesive to improve the waterproofness of the intelligent monitoring device.

[0027] The heart rate and blood oxygen sensor 18 is based on the PPG principle (known technical content) and needs to be in contact with human skin. The heart rate and blood oxygen sensor 18 uses a wire to pass through the reserved opening on the back side of the shell 21 to reach the left neck of the protective suit, and is placed in the silicone shell 26 to monitor the wearer's heart rate and blood oxygen value by detecting the changes in incident light and reflected light at the neck. The reserved opening on the silicone shell 26 exposes the detection light LED 27 on the heart rate and blood oxygen sensor 18.

[0028] The body temperature sensor 14 is placed in the protective suit inner layer placement bag to monitor the internal temperature of the protective suit, and is sealed with a waterproof zipper. The power pin and digital signal pin of the microcontroller will use wires to pass through the reserved opening on the rear side of the shell 21 and the reserved opening of the protective suit inner layer, reach the protective suit inner layer placement bag, and be electrically connected to the body temperature sensor 14.

[0054] Specifically, the detailed circuit diagram of the charging unit 5 of the charging and discharging module 1 of this embodiment is as follows: Figure 4 As shown, it includes a chip U1, a light emitting diode D1, a Schottky diode D2, a voltage input terminal VIN, a resistor R1, a resistor R2, and a capacitor C1. The model of the chip is TP4065, the model of the light emitting diode D1 is GHC-YR1S2, the model of the Schottky diode D2 is B5819WSL, the resistance of the resistor R1 is 22KΩ, the resistance of the resistor R2 is 2.2KΩ, and the capacity of the capacitor C1 is 100nF.

[0055] This embodiment uses a charging circuit chip of model TP4065, which has high compatibility and is compatible with programmable charging currents from 3mA to 600mA. It also has positive and negative pole reverse connection protection and input power supply positive and negative pole reverse connection protection functions. When the positive and negative poles of the battery are reversely connected to the TP4065 current output BAT pin or the positive and negative poles of VIN are reversely connected to the VCC pin of TP4065, TP4065 will shut down and display a fault state, with no charging current, the charging indication pin CHRG is in a high impedance state, and the light-emitting diode D1 is off, which will greatly protect the stability and safety of the current input and output. One end of the Schottky diode D2 of model B5819WSL is connected to the voltage input terminal VIN, and the other end is connected to the positive input power supply voltage pin VCC of the chip U1. When the power supply is reversed or the VCC pin of the chip U1 is abnormally high voltage, the Schottky diode D2 will quickly turn on to achieve current shunting and protect the subsequent circuit from damage. This model of Schottky diode adopts SOD-323 packaging, which is small and suitable for integration in circuit boards with limited space. One end of the light-emitting diode D1 is connected to the resistor R1, and the other end is connected to the charging status indicator pin CHRG of the chip U1. When the charger charges the battery, the CHRG pin is pulled to a low level by the internal switch, and the light-emitting diode D1 lights up, indicating that charging is in progress. The resistance value of the resistor R1 is 22K, which is used to shunt the light-emitting diode D1 to avoid damage caused by excessive current flowing into the light-emitting diode D1 from the voltage input terminal VIN. One end of the resistor R2 is connected to the charging current setting pin PROG of the chip U1, and the other end is grounded. The charging current is set by the resistance of the resistor connected between the PROG pin and the ground. By simulating the relevant device parameters, when the resistance of the resistor is 2.2KΩ, the charging current is about 500mA, which meets the charging current requirements of the embodiment of the utility model, so the resistance of the resistor R2 is selected to be 2.2KΩ. One end of the capacitor C1 is connected to the charging current output pin BAT of the chip U1, and the other end is grounded. The charging current output pin BAT provides charging current to the battery. The capacity of the capacitor C1 is used to adjust the frequency of the pulse signal emitted by the charging status indication terminal pin CHRG of the chip U1 in the standby state without battery.

[0056] As described in patent CN 220594278 U, the protective clothing top includes an outer layer 19 of a flame-retardant and fireproof surface layer, a middle layer 20 of a composite foam material core layer, and an inner layer of a comfortable lining layer, and the three layers are closely arranged and fitted. The outer layer 19 of a flame-retardant and fireproof surface layer is composed of a flame-retardant and fireproof aramid surface layer and a flame-retardant and low water absorption cushion layer. The aramid surface layer can wrap the internal material at thousands of degrees Celsius, and the combination of a flame-retardant and low water absorption cushion layer (such as a commonly used aerogel cotton) can further protect the internal structure from being directly contacted and burned by the flame. The middle layer 20 of the composite foam material core layer serves as the main buoyancy function and heat insulation function. The composite foam material is light and high-strength, and the buoyancy loss under long-term underwater action is small, and it has a thermal conductivity of less than 0.2W / (m·K), which can make the overall structure block a large amount of heat transfer when used in risk-avoidance clothing, and protect human skin from burns. The inner comfort lining is composed of a flame retardant low water absorption cushion layer, a heat-resistant elastic rubber layer / flame retardant and fire-resistant aramid surface layer. The flame retardant low water absorption cushion layer separates the upper working layer from the lining. The lining in contact with the human body is mainly made of heat-resistant elastic rubber or flame retardant and fire-resistant aramid, which are soft and can block heat.

[0057] As shown in patent CN 308242009 S, in order to solve the impact of hard clothing made of composite foam material on human activities, the core layer of the composite foam material is divided into many solid material modules on the clothing according to the distribution of human muscles and the rotation range of joints.

[0058] The shell 21 is made of polyimide material with good high temperature resistance and heat insulation properties, and is sprayed with high temperature resistant paint, such as silicone, on the outer layer to improve the tolerance of the intelligent monitoring device to high temperatures. The shell 21 replaces the original solid material module near the left chest of the middle layer of the protective clothing to achieve the integration of the intelligent monitoring device and the protective clothing.

[0059] The charging and discharging module 1 , the signal acquisition and processing module 2 , the display module 3 , and the communication module 4 are integrated on a PCB board. The PCB board is placed in the housing 21 and fixed by providing a card slot inside the housing 21 .

[0060] The positioning module 17 , the infrared radiation heat sensor 13 , the smoke sensor 15 , and the carbon monoxide sensor 16 are all placed in the housing 21 and fixed by providing a card slot inside the housing 21 .

[0061] The sensing probes 22, 23 of the smoke sensor and the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor need to be in contact with the external environment. Therefore, during integration, a reserved opening will be set on the shell 21 according to the shape of the sensing probes 22, 23 and the temperature measuring probe 24; at the same time, a reserved opening will be set on the left chest part of the outer layer of the protective clothing according to the shape of the sensing probes 22, 23 of the smoke sensor, the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor, so that the sensing probes 22, 23 of the smoke sensor, the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor can fully contact with the environment to improve the measurement accuracy. The connection between the sensing probes 22, 23 of the smoke sensor, the carbon monoxide sensor and the temperature measuring probe 24 of the infrared radiation heat sensor and the reserved opening of the shell 21 and the outer layer of the protective clothing will be sealed with an adhesive to improve the waterproofness of the intelligent monitoring device.

[0062] The positioning module 17 includes a positioning unit and an antenna 25. The antenna will pass through the reserved opening at the rear of the shell 21 to reach the collar of the protective clothing, and be fixed to the collar of the protective clothing using an adhesive. The connection between the antenna 25 and the reserved opening at the rear of the shell 21 is sealed with an adhesive to improve the waterproofness of the monitoring device.

[0063] The heart rate and blood oxygen sensor 18 is measured based on the PPG principle and needs to be in contact with human skin. The heart rate and blood oxygen sensor 18 uses a wire to pass through the reserved opening on the rear side of the shell 21 to reach the left collar of the protective suit, and monitors the wearer's heart rate and blood oxygen value by detecting the changes in incident light and reflected light at the neck. The heart rate and blood oxygen sensor 18 is placed in a silicone shell 26, which has good durability and waterproofness, and is soft and comfortable. The wire is tied together with an iron wire or aluminum wire with a shaping function to adjust the position of the heart rate and blood oxygen sensor 18 by adjusting the bending direction of the iron wire, so that the heart rate and blood oxygen sensor 18 can fit closely with the wearer's neck, thereby improving the measurement accuracy. The reserved opening on the silicone shell 26 exposes the detection light LED27 on the heart rate and blood oxygen sensor 18.

[0064] The body temperature sensor 14 is placed in the inner layer placement bag of the protective suit to monitor the internal temperature of the protective suit, and is sealed with a waterproof zipper. The power pin and digital signal pin of the microcontroller will use wires to pass through the reserved opening on the rear side of the shell 21 and the reserved opening on the inner layer of the protective suit to reach the inner layer placement bag of the protective suit and be electrically connected to the body temperature sensor 14. The connection between the wire and the reserved opening on the rear side of the shell 21 and the reserved opening on the inner layer of the protective suit is sealed with an adhesive.

[0065] Working method and process of this utility model:

[0066] The charging and discharging module 1, the signal acquisition and processing module 2, the display module 3, and the communication module 4 are connected as shown in the attached Figure 2 , 3 The circuit diagram shown is connected, and each module is fixed at a predetermined position to form a complete intelligent monitoring device, and then the intelligent monitoring device is integrated on the protective clothing.

[0067] After debugging is completed, turn on the power switch and the cloud management platform, and the sensor unit data will be uploaded to the cloud management platform through the communication module and presented in the form of data tables and curves. The body temperature sensor will monitor and record the internal temperature of the protective clothing, the heart rate and blood oxygen sensor will monitor and record the wearer's real-time heart rate and blood oxygen value, the positioning module will monitor the wearer's location information in real time and record it in the form of longitude and latitude, the smoke sensor and carbon monoxide sensor will monitor and record the smoke and carbon monoxide concentration in the fire scene in real time, and the infrared radiation heat sensor will monitor the heat energy distribution in the fire scene in real time and generate infrared imaging. When the data monitored by the sensor exceeds the set threshold, it will automatically alarm the cloud management platform, reminding the command center and other relevant department managers to take timely measures to protect the life and health of the wearer and avoid accidents.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
