Description

Technical Field

[0001] The present invention relates to the technical field of intelligent devices, and in particular to a thermal safety assurance system and method for food delivery personnel. Background Art

[0002] With the rapid development of the food delivery industry, the number of food delivery riders in China has reached 13 million in 2023, becoming an important part of social and economic activities. At present, food delivery riders face tremendous work pressure in their daily work, especially in the hot summer noon period (such as 10:00-14:00). They need to complete an average of 4-6 orders per hour and often need to work continuously for 4-6 hours. This phenomenon is particularly obvious in my country's economically developed large cities. In addition, since my country's southeastern coastal areas have a subtropical climate, the outdoor temperature in summer is as high as 40°C. The harsh working environment such as high temperature, direct sunlight and insufficient air circulation makes food delivery riders prone to heat exposure, thereby causing health problems such as heat stroke.

[0003] Although most companies will uniformly distribute work clothes with quick-drying function, since work clothes only have quick-drying function and cannot alleviate the high temperature and high radiation problems caused by hot weather, riders will choose to wear sun protection clothing on the basis of work clothes. Although it reduces radiation, it further increases the body temperature and greatly increases the possibility of heat stroke. At the same time, the special nature of the work of food delivery riders requires frequent operation of mobile phones. In order to increase the delivery speed, most riders often operate their mobile phones while riding, and they tend to ignore the traffic conditions in their environment, which poses a huge safety hazard.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Embodiment 1

[0031] like Figure 1-Figure 8 As shown, the present invention provides a thermal safety protection system for food delivery drivers, including a helmet 1, a vest 2 and a waist-hanging fan 3: An intelligent control unit and a power supply unit are arranged inside the helmet 1. The power supply unit is used to supply power to the intelligent control unit. An operation key for starting or shutting down the intelligent control unit is arranged on the helmet 1. An air intake pipe 11 is arranged outside the helmet 1. One end of the air intake pipe 11 is arranged inside the helmet 1. A mounting hole is opened on the rear side of the outer surface of the helmet 1. The air intake pipe 11 is fixedly arranged in the mounting hole, so as to ensure that the air intake pipe 11 is located at the rear side of the helmet 1, and avoid the air intake pipe 11 at other positions of the helmet 1 causing certain influence on the rider; Furthermore, the helmet 1 has a protective layer inside to improve wearing comfort and increase safety, and an internal support frame structure is provided inside the helmet 1 to prevent the rider's head from contacting the intelligent control unit and the power supply unit. It is worth noting that this structural technology is conventional technology and is not elaborated in detail in this article.

[0032] The intelligent control unit includes a temperature and humidity sensor 12, a first single-chip microcomputer 13, a bone conduction headset module 14 and a protective cover 15. The temperature and humidity sensor 12 is used to monitor the environmental state inside the helmet 1 in real time. The first single-chip microcomputer 13 is used to receive the monitoring data of the temperature and humidity sensor 12 and perform data analysis and processing. The first single-chip microcomputer 13 is connected to the mobile client through the Bluetooth module and is used to receive the mobile client takeaway APP order information. The bone conduction headset module 14 is used to perform voice control on the first single-chip microcomputer 13 and is also used to broadcast order information, safety information and communication information. An integrally formed air pipe 21 is provided on the outer surface of the vest 2. The air pipe 21 is evenly distributed on the front and back of the vest 2. One end of the air pipe 21 is connected to a first elastic bellows 22. The other end of the air pipe 21 is connected to a second elastic bellows 23. The second elastic bellows 23 is sealed and connected to one end of the air inlet pipe 11 through a connecting pipe head. A bucket-shaped cover 31 connected to the outer shell of the waist-hanging fan 3 is provided at the air outlet of the waist-hanging fan 3, and a semiconductor cooling sheet 32 ​​located at the air inlet of the waist-hanging fan 3 is inlaid on the outer shell of the waist-hanging fan 3, a second single-chip computer 33 for regulating the power of the waist-hanging fan 3 and the semiconductor cooling sheet 32 ​​is installed, and a detachable power supply 34 for supplying power to the waist-hanging fan 3, the semiconductor cooling sheet 32 ​​and the second single-chip computer 33 is provided; Among them, the waist-hanging fan 3 is an existing conventional technology and is not described in detail in this article. The installation of the second single-chip microcomputer 33 and the electrical connection between the second single-chip microcomputer 33 and the waist-hanging fan 3, the semiconductor cooling plate 32 and the detachable power supply 34 are basic operations for technical personnel in this field, and thus are not elaborated in detail in this article. Therefore, after the waist-hanging fan 3, the semiconductor cooling plate 32 and the second single-chip microcomputer 33 are powered, the power adjustment of the waist-hanging fan 3 and the semiconductor cooling plate 32 can be achieved by controlling the second single-chip microcomputer 33 to achieve a cooling effect.

[0033] Furthermore, the bucket-shaped cover 31 can be snapped onto the air outlet of the waist-hanging fan 3 in a snap-on manner, wherein the snap-on manner can be a snap-on manner similar to the battery back cover of a remote control. Specifically, a snap-on groove is provided on the outside of the air outlet of the waist-hanging fan 3, and a positioning protrusion is provided on one side of the bottom of the bucket-shaped cover 31, and an elastic snap block is provided on the other side of the bottom of the bucket-shaped cover 31, thereby the bucket-shaped cover 31 can be snapped into the snap-on groove at the top of the waist-hanging fan 3 to ensure that the wind at the air outlet of the waist-hanging fan 3 is discharged through the branch pipe at the top of the bucket-shaped cover 31, and the branch pipe provided on the bucket-shaped cover 31 is used to cooperate with one end of the first elastic bellows 22 to ensure that the airflow blown out by the waist-hanging fan 3 is blown into the air supply pipe 21.

[0034] It is worth noting that the connection between the bucket-shaped cover 31 and the waist-hanging fan 3 is similar to the buckle-type buckle of the battery back cover of the remote control. This technology is conventional and will not be elaborated in detail herein.

[0035] Furthermore, the number of waist-hanging fans 3 matches the number of air pipes 21. When one air pipe 21 is used, one waist-hanging fan 3 is used, and the distribution of one air pipe 21 can evenly cover the front and back of the vest 2. When two air pipes 21 are used, two waist-hanging fans 3 are used. After the semiconductor refrigeration plate 32 generates cold air, the cold air is converted into cold wind through the waist-hanging fan 3 and sent to the outside of the vest 2 and the inside of the helmet 1, completing the cooling process and ensuring the thermal safety of the rider.

[0036] Furthermore, as a conventional technology, the detachable power supply 34 can be disassembled and replaced to ensure that the rider has sufficient power during use.

[0037] The waist-mounted fan 3 is used to deliver cold air into the helmet 1 through the air supply pipe 21 and the air intake pipe 11, and the intelligent control unit is used to remotely control the second single-chip microcomputer 33, wherein the main control method is that the first single-chip microcomputer 13 communicates with the second single-chip microcomputer 33 through a Bluetooth module.

[0038] Furthermore, the power supply unit includes a micro solar module 4 installed on the surface of the helmet 1, a micro battery module 5 arranged inside the helmet 1 and used to store electrical energy, and a charging port 6 arranged inside the helmet 1 and used to charge the micro battery module 5, and the micro solar module 4 and the micro battery module 5 are electrically connected to the intelligent control unit respectively.

[0039] Specifically, the micro solar module 4 is installed on the top of the outer side of the helmet 1, which can ensure that the rider can collect solar energy when riding outdoors to power each module in the intelligent control unit. At the same time, the micro solar module 4 can also store part of the electricity in the micro battery module 5, so as to achieve the effect of using it when solar energy cannot be generated on cloudy days. At the same time, the charging port 6 can also be used to charge the micro battery module 5 to ensure that the micro battery module 5 supplies power to the modules in the intelligent control unit.

[0040] Furthermore, the selected equipment and modules are all lightweight and miniature, ensuring that the weight of the assembled equipment will not cause pressure and burden to the rider when wearing it.

[0041] Furthermore, the micro solar module 4 is not limited to the figure. The micro solar module 4 can be installed on the top of the helmet 1 using a curved solar panel to ensure the flatness of the outer surface of the helmet 1. The outer surface of the curved solar panel should be slightly lower than the outer surface of the helmet 1 during installation, thereby protecting the solar panel and reducing the possibility of damage.

[0042] Combination Figure 2 As shown, as a further feature, two gas pipes 21 are provided, one end of the two gas pipes 21 is commonly connected to a three-way pipe 24 , and one end of the three-way pipe 24 is sealedly connected to one end of the second elastic bellows 23 .

[0043] Specifically, the two air pipes 21 are distributed in an S shape from the front side of the vest 2 to the back of the vest 2, so that the rider can feel the temperature drop on the back and chest, and the two air pipes 21 are connected to a three-way pipe 24 on the back of the vest 2, so that the cold air flows in the two air pipes 21 are combined and transmitted to the helmet 1, thereby ensuring the cooling effect inside the helmet 1.

[0044] Combination Figure 3 As shown, as a further feature, the outer shell surface of the waist-hanging fan 3 is connected to a ventilation shell 35, the cooling surface of the semiconductor refrigeration sheet 32 ​​is connected to a plurality of cooling fins 36 through silicone, the cooling fins 36 are located at the air inlet of the waist-hanging fan 3, and the heat dissipation surface of the semiconductor refrigeration sheet 32 ​​is connected to a plurality of cooling fins 37 through silicone, and the cooling fins 37 are located in the inner cavity of the ventilation shell 35.

[0045] Specifically, a plurality of cooling fins 36 are vertically distributed at the air inlet of the waist-hanging fan 3, effectively ensuring the cooling effect of the airflow introduced by the waist-hanging fan 3, and a plurality of heat dissipation fins 37 are horizontally distributed inside the ventilation shell 35, prompting the rider to generate wind when riding. The wind enters through the front port of the ventilation shell 35 and is discharged through the rear port, effectively achieving the effect of dissipating heat from the heat dissipation fins 37.

[0046] Combination Figure 6 and Figure 7 As shown, as a further feature, mesh holes 25 are respectively provided on the front and back of the vest 2 , and the air pipes 21 are evenly distributed at the mesh holes 25 .

[0047] Specifically, a plurality of mesh holes 25 are provided on the vest 2 so that after the cold air is introduced into the air delivery pipe 21 , the outside of the human body can be locally cooled through the mesh holes 25 , and the human body can feel the cooling temperature through the mesh holes 25 .

[0048] Furthermore, the vest 2 is made of lightweight, breathable polyester fiber material to enhance air flow and sweat evaporation, improve cooling efficiency, and reduce the burden on riders while effectively ensuring that the vest 2 fits well with summer clothes.

[0049] Furthermore, the vest 2 is connected with a zipper, and the zipper design of the vest 2 makes it convenient for the rider to wear it.

[0050] Combination Figure 1 and Figure 2 As shown, a Velcro 26 for fixing the first elastic bellows 22 or the second elastic bellows 23 is sewn onto the outer surface of the vest 2.

[0051] Specifically, three Velcro strips 26 are provided, one of which is located in the middle of the back of the vest 2, and the other two are located at the waist of the vest 2. Therefore, the Velcro strips 26 on the back are convenient for storing and fixing the second elastic bellows 23, so that when the vest 2 is used separately from the helmet 1, the second elastic bellows 23 with good ductility can be stored to the back for easy use. The Velcro strips 26 on both sides of the waist of the vest 2 are convenient for storing and fixing the corresponding first elastic bellows 22, so that after the first elastic bellows 22 is separated from the bucket-shaped cover 31, the storage stability of the first elastic bellows 22 is ensured.

[0052] Combination Figure 7 As shown, as a further feature, the cross-section of the air pipe 21 is rectangular, and the outer surface of the air pipe 21 is provided with a stabilizing cloth 7 sewn to the vest 2, and an insulation layer is provided between the stabilizing cloth 7 and the air pipe 21.

[0053] Specifically, the air pipe 21 can be a square pipe, because its square side has a larger contact area with the vest 2, which is beneficial for the human body to feel the temperature drop on the outside of the body, thereby achieving a better cooling effect on the rider's back and chest. The air pipe 21 is made of a lighter plastic material, which effectively reduces the overall weight of the vest 2 and improves wearing comfort. At the same time, when the air pipe 21 is sewn and fixed to the vest 2 by the stabilizing cloth 7, an insulation layer is arranged between the stabilizing cloth 7 and the air pipe 21, so that the insulation layer covers three sides of the air pipe 21 to ensure the cooling effect inside the air pipe 21 and avoid the loss of the cooling effect.

[0054] Combination Figure 1As shown, as a further feature, the outer surface of the helmet 1 is provided with ventilation holes 16 for promoting fluid circulation.

[0055] Specifically, the vents 16 are used to communicate with the inner cavity of the helmet 1, and four vents 16 are provided, with two vents in each group. One group of vents 16 is located at the front position of the outer surface of the helmet 1, and the other group of vents 16 is located at the rear position of the outer surface of the helmet 1, thereby promoting the flow of air inside the helmet 1. According to the principles of fluid dynamics, the air flow forms an effective circulation, which has the effect of natural ventilation and ensures that the cold air blown in by the waist-hanging fan 3 flows outward through the vents 16.

[0056] Combination Figure 5 As shown, as a further feature, the inner surface of the helmet 1 is provided with a distribution pipe 17 for dispersing the fluid, one end of the distribution pipe 17 is sealedly connected to one end of the air intake pipe 11 , and a plurality of cold air holes 18 are provided on the surface of the distribution pipe 17 .

[0057] Specifically, the distribution pipe 17 has various shapes, such as "U" shape, "O" shape or spiral shape, and has a connecting port. The distribution pipe 17 is sealed and connected to one end of the air intake pipe 11 through the connecting port, ensuring that the airflow in the air intake pipe 11 enters the interior of the distribution pipe 17 and is finally discharged outward through a plurality of cold air holes 18, thereby causing the cold airflow to be evenly distributed throughout the interior of the helmet 1, ensuring that the rider feels a certain cooling effect, improving comfort, and reducing the possibility of heatstroke.

[0058] Combination Figure 1 As shown, as a further feature, a key switch 38 for controlling the second single-chip computer 33 is provided on the housing of the waist-hanging fan 3 , and the second single-chip computer 33 regulates the power of the waist-hanging fan 3 and the semiconductor cooling plate 32 through the key switch 38 .

[0059] Specifically, there are multiple button switches 38, including a start switch, an adjustment switch and an off switch. The start switch and the off switch are used to control the opening or closing of the waist-hanging fan 3 and the semiconductor cooling plate 32, and the adjustment switch is used to adjust the power of the waist-hanging fan 3 and the semiconductor cooling plate 32 to achieve the required power, thereby reducing the temperature of the rider's back and chest, reducing the risk of heat stroke, and ensuring the rider's safety.

[0060] Furthermore, a plurality of reflective strips 8 are respectively provided on the rear sides of the helmet 1 and the vest 2 to increase the safety of the rider during night riding. Embodiment 2

[0066] Therefore, during riding, the temperature and humidity sensor 12 is used to monitor the environment inside the helmet 1 in real time, so that the temperature and humidity sensor 12 can input the monitoring environment parameters into the first single-chip microcomputer 13, and then the first single-chip microcomputer 13 is used to calculate the thermal discomfort index DI based on the monitoring parameters, and compare it with the preset threshold value of the thermal discomfort index DI. After the comparison, the comparison data can be broadcasted through the bone conduction headset module 14, and then the takeaway rider can issue voice commands to control the first single-chip microcomputer 13 according to the broadcast data, so that the first single-chip microcomputer 13 remotely controls the second single-chip microcomputer 33, so as to achieve the waist-hanging fan 3 and the semi-circular fan 3. The power regulation effect of the conductor cooling sheet 32 ​​prompts the waist-mounted fan 3 to increase the wind speed and quickly send the cold air flow into the air pipe 21 and the air intake pipe 11, and finally send it to the inside of the helmet 1 and discharge it through the cold air holes 18 on the distribution pipe 17, ensuring that the cold air flow is evenly distributed throughout the inside of the helmet 1, prompting the rider to feel a certain cooling effect, improving comfort, and reducing the possibility of heatstroke. At the same time, the contact between the air pipe 21 and the vest 2 is conducive to the human body feeling the temperature drop on the outside of the body, achieving a cooling effect on the rider's back and chest, and providing safety protection for delivery riders working during the hot summer noon.

[0067] It is worth noting that this method is not only suitable for deliverymen, but also generally applicable to other outdoor workers and people who need to ride. Embodiment 4

[0068] A method for a thermal safety assurance system for food delivery drivers, when the food delivery drivers are facing high temperatures and need to cool down, includes a manual mode, and the manual mode includes the following steps: Step 301: Use the bone conduction headset module 14 to control the first single-chip microcomputer 13 to switch the automatic mode or the voice mode to the manual mode; Step 302: Monitor the internal environment of the helmet 1 in real time through the temperature and humidity sensor 12; Step 303: input the monitoring environment parameters into the first single chip microcomputer 13, so that the first single chip microcomputer 13 calculates the thermal discomfort index (DI) value based on the monitoring data, and simultaneously broadcasts the thermal discomfort index (DI) value through the bone conduction headset module 14; Step 304: According to the reported thermal discomfort index (DI) value or his / her own feeling, the delivery person controls the second single-chip microcomputer 33 through the key switch 38, so that the second single-chip microcomputer 33 adjusts the power of the waist-hanging fan 3 and the semiconductor cooling plate 32; Step 305 , the cold air flow is introduced into the air delivery pipe 21 and the air intake pipe 11 through the waist-mounted fan 3 , and finally sent to the interior of the helmet 1 and discharged through the cold air holes 18 on the distribution pipe 17 .

[0069] Specifically, after the deliveryman puts on the helmet 1 and the vest 2 normally, he uses the connecting pipe head to connect one end of the second elastic bellows 23 with the air intake pipe 11, and at the same time, clamps the waist fan 3 on the waist belt, so that one end of the first elastic bellows 22 is connected to the bucket-shaped cover 31 through the connecting pipe head, and turns on the waist fan 3 and the semiconductor cooling plate 32 through the starting switch at the button switch 38, and then starts the intelligent control unit through the operation key on the helmet 1, and finally controls the first single-chip microcomputer 13 through the bone conduction headset module 14, so that the first single-chip microcomputer 13 switches from the automatic mode or voice mode of the second single-chip microcomputer 33 to the manual mode.

[0070] Therefore, during riding, the temperature and humidity sensor 12 is used to monitor the environment inside the helmet 1 in real time, so that the temperature and humidity sensor 12 can input the monitoring environment parameters into the first single-chip microcomputer 13, and then the first single-chip microcomputer 13 is used to calculate the thermal discomfort index DI based on the monitoring parameters, and compare it with the preset threshold value of the thermal discomfort index DI. After the comparison, the comparison data can be broadcasted through the bone conduction headset module 14, and then the takeaway rider can manually adjust the key switch 38 according to the broadcast data or his own feelings, so that the second single-chip microcomputer 33 controls the waist hanging fan 3 and the semiconductor after the key switch 38 is adjusted. The power of the cooling sheet 32 ​​is adjusted to ensure that the waist-hanging fan 3 quickly delivers the cold air flow into the air pipe 21 and the air intake pipe 11 after the wind speed is increased, and finally delivers it to the inside of the helmet 1 and is discharged through the cold air holes 18 on the distribution pipe 17, ensuring that the cold air flow is evenly distributed throughout the inside of the helmet 1, prompting the rider to feel a certain cooling effect, improving comfort, and reducing the possibility of heatstroke. At the same time, the contact between the air pipe 21 and the vest 2 is conducive to the human body feeling the temperature drop on the outside of the body, achieving a cooling effect on the rider's back and chest, and providing safety protection for delivery riders working during the hot summer noon.

[0071] It is worth noting that the manual mode is mainly used when the bone conduction headset module 14 in the intelligent control unit prompts that the micro battery module 5 is low on power. The switched manual mode can ensure that the waist fan 3 and the semiconductor cooling plate 32 are still adjustable when the micro battery module 5 is out of power, so that the rider can feel the cooling effect. It should be noted that when the micro battery module 5 is out of power, the rider only needs to control and adjust according to his own feelings.

[0072] It should be emphasized that the rider's voice control of the power of the waist fan 3 and the semiconductor cooling plate 32 has a higher priority than the intelligent control unit.

[0073] In the second, third and fourth embodiments, the first single chip computer 13 calculates the thermal discomfort index (DI) value based on the monitoring data using the formula: .

[0074] Based on the DI value, the intelligent control unit can remotely control the waist-hanging fan 3 and the semiconductor cooling plate 32, so that the waist-hanging fan 3 can adjust the wind speed and the semiconductor cooling plate 32 can adjust the cooling degree to ensure the cooling effect.

[0075] It is worth noting that when the DI value exceeds the preset threshold, the first single-chip microcomputer 13 in the automatic mode can control the second single-chip microcomputer 33 to increase the power of the waist-hanging fan 3 and the semiconductor cooling plate 32 to achieve the cooling effect, otherwise the power is reduced, so as to achieve the purpose of on-demand, reduce the temperature of the rider's back and chest, and ensure the rider's thermal safety; and the specific power standards of the waist-hanging fan 3 and the semiconductor cooling plate 32 based on DI are shown in Table 1: Table 1 Power standards based on thermal discomfort index DI

At the same time, it effectively improves the rider's food delivery efficiency and effectively reduces the incidence of traffic accidents, which has a certain degree of safety.

[0077] The safety information includes: when the deliveryman is riding to deliver, the bone conduction headset module 14 in the intelligent control unit will give voice prompts according to the route planned by the mobile client map APP navigation; Specifically, the voice prompts for safety information mainly include intelligently optimizing routes based on the real-time traffic conditions of the delivery address, planning the most efficient pick-up and delivery routes, and providing riders with route optimization services for multiple travel modes such as cycling and walking, thereby comprehensively considering efficiency and safety and reducing traffic risks caused by rushing; at the same time, it also reduces the problem of safety risks for delivery riders who check map navigation information while riding.
