[0029] The following will describe in detail the embodiments of the technical solutions of the present invention in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and thus are only examples and cannot be used to limit the protection scope of the present invention.

[0030] It should be noted that unless otherwise specified, the technical terms or scientific terms used in the present application should have the ordinary meanings understood by those skilled in the art to which the present invention belongs.

[0031] Such as Figure 1 and Figure 2As shown, the present application provides a smart sun protection hat, which includes: a hat body 10, a temperature and humidity sensor 100, a power module 200, a cooling module and a main controller 400, wherein the temperature and humidity sensor 100, the power module 200, the cooling module and the main controller 400 are respectively fixed on the hat body 10, and the temperature and humidity sensor 100, the power module 200 and the cooling module are respectively electrically connected to the main controller 400; the hat body 10 can be a straw hat or a safety helmet. In the case of a straw hat, a reinforcing plate can be provided on the brim to improve the support strength.

[0032] The temperature and humidity sensor 100 is used to sense the temperature and humidity around the cap body 10; the temperature and humidity sensor 100 is a sensor device equipped with hygroscopic and thermal elements that can be used to measure temperature and humidity. The temperature and humidity sensor 100 is widely used in various fields of production and life due to its small size and stable performance.

[0033] The power module 200 is used to provide power to the temperature and humidity sensor 100, the cooling module and the main controller 400; the power module 200 can ensure the normal operation of the temperature and humidity sensor 100, the cooling module and the main controller 400.

[0034] The cooling module is used to cool the periphery of the cap body 10 ; the cooling module usually uses a physical method to cool.

[0035] The main control module is used to control the cooling module to cool down when the temperature and humidity sensor 100 detects that the temperature and humidity exceed the preset threshold. The main control module mainly controls each functional unit and issues a cooling instruction. In this embodiment, the main control module mainly refers to an STM32 microcontroller.

[0036] In this embodiment, wearing a smart sun hat can provide a certain shade. When the temperature and humidity sensor 100 detects that the temperature and humidity exceed the preset threshold, the cooling module is controlled to cool down. The cooling module can reduce the temperature of the staff's head, so that the staff wearing the smart sun hat can work better, reduce the risk of heat stroke, and reduce the damage of high temperature to the body.

[0037] In one embodiment of the present application, the cooling module includes a fan 310, and two fans 310 are provided. The two fans 310 are arranged at intervals on the rear side of the cap body 10. The fan 310 can increase the air flow rate when rotating, take away the heat of the human body, and thus cool down. By arranging the fan 310 on the rear side of the cap body 10, it can be closer to the human neck position, which is conducive to reducing the temperature of the head. By setting two fans 310, the cooling effect is improved.

[0038] In an embodiment of the present application, the cooling module further includes a humidifying sprayer 320. There are two humidifying sprayers 320, and one humidifying sprayer 320 is correspondingly provided with one fan 310. Moreover, the humidifying sprayer 320 is arranged in front of the direction where the fan 310 blows air. The humidifying sprayer 320 can provide water mist, and the water mist can also take away heat when evaporating. And, the water mist can be blown towards the human body by the fan 310, which is more conducive to reducing the temperature of the head. Moreover, the water mist can also separate the head from the high temperature outside, forming a protective barrier.

[0039] In an embodiment of the present application, the intelligent sun hat further includes a first control button 301 and a first electromagnetic relay 302. The first control button 301 is connected to the first electromagnetic relay 302, and the first electromagnetic relay 302 is electrically connected to the two fans 310. By pressing the first control button 301, the opening and closing of the first electromagnetic relay 302 can be controlled, so as to control the power supply to the fans 310. The temperature and humidity sensor 100 controls whether the fans 310 rotate by judging the current temperature and whether the first control button 301 is pressed. When the temperature exceeds 30 °C, the fans 310 are automatically turned on, and if it is lower than 30 °C, they are automatically turned off. At the same time, the first control button 301 can also be used for control. Thus, a mode combining physical and intelligent control is realized.

[0040] In an embodiment of the present application, the intelligent sun hat further includes a lighting lamp 500, a second control button 501 and a second electromagnetic relay 502. The second control button 501 is connected to the second electromagnetic relay 502, and the second electromagnetic relay 502 is connected to the lighting lamp 500. The lighting lamp 500 is arranged on the front side of the hat body 10. By providing the lighting lamp 500, lighting can be provided in case of insufficient light. By pressing the second control button 501, the opening and closing of the second electromagnetic relay 502 can be controlled, so as to control the lighting or extinguishing of the lighting lamp 500.

[0041] In an embodiment of the present application, the intelligent sun hat further includes a third control button 321, and the third control button 321 is electrically connected to the two humidifying sprayers 320. By pressing the third control button 321, the operation of the humidifying sprayers 320 can be controlled.

[0042] In an embodiment of the present application, the power supply module 200 includes a storage battery 210. The storage battery 210 is electrically connected to the main controller 400. The power supply module 200 further includes a solar panel 220 and a transfer board 230. The solar panel 220 is electrically connected to the transfer board 230. The solar panel 220 is arranged on the outer side of the hat body 10, and the transfer board 230 is electrically connected to the main controller 400. The storage battery 210 can provide power. In cooperation with the solar panel 220 and the transfer board 230, solar energy can be converted into electrical energy and can also cooperate with the power supply to increase the battery life of the intelligent sun hat.

[0043] In an embodiment of the present application, the intelligent sun protection cap further includes an intelligent voice module 600. The intelligent voice module 600 is electrically connected to the main controller 400. The intelligent voice module 600 is used to perform voice broadcast when the temperature exceeds a preset temperature, reminding the user to pay attention to preventing heatstroke and cooling down. The intelligent voice module 600 is connected to a speaker 700, and through the speaker 700, the wearer can better receive messages.

[0044] As Figure 3 shown, the present application also provides a control method for an intelligent sun protection cap. The control method is applied to the intelligent sun protection cap. The control method includes:

[0045] Step S10, controlling the temperature and humidity sensor 100 to detect the temperature and humidity around the cap body 10. When the detected temperature and humidity exceed a preset threshold, a cooling instruction is generated and sent to the cooling module; wherein, the temperature and humidity sensor 100 transmits the detected temperature and humidity to the main controller 400, and the main controller 400 compares the temperature and humidity with the preset threshold. When both the temperature and humidity exceed the standard, a cooling instruction is generated. In the present application, STM32F103C8T6 is used as the main controller. At the same time, it is necessary to configure the clock of the main controller, initialize the delay function, and initialize the configuration of the IO ports. The systemini() function and the SetSysClock() function are used for clock configuration. The LED_GPIO_Config() function is used for the initialization configuration of the IO ports.

[0046] Step S20, controlling the cooling module to cool down according to the cooling instruction. The cooling instruction is sent to the cooling module through the main controller 400, and the main controller 400 controls the cooling module.

[0047] In this embodiment, wearing the intelligent sun protection cap can play a certain role in shading. Moreover, when the temperature and humidity sensor 100 detects that the temperature and humidity exceed the preset threshold, the cooling module is controlled to cool down. Through the cooling module, the temperature of the staff's head can be reduced, so that the staff wearing the intelligent sun protection cap can work better, reducing the situation of heatstroke and reducing the harm of high temperature to the body.

[0048] As Figure 4 shown, in an embodiment of the present application, the step of controlling the temperature and humidity sensor 100 to detect the temperature and humidity around the cap body 10 includes:

[0049] Step S110, reading the high and low levels of the data interface of the temperature and humidity sensor 100 to obtain a set of binary data, and converting the binary data into hexadecimal data;

[0050] Step S120, converting the hexadecimal data into decimal data, and using the decimal data as the temperature and humidity data detected by the temperature and humidity sensor 100.

[0051] The temperature and humidity sensor 100 reads the current temperature and humidity changes through the IO port. However, the IO port only has high and low levels, that is, two possibilities of 0 and 1. But the binary numbers composed of eight bits in a group are converted into hexadecimal and then into decimal to obtain more accurate values of temperature and humidity. There are a total of forty binary numbers. Through conversion, it finally presents a two-digit temperature, a two-digit humidity, and a parity bit. The parity bit is used to ensure the correct reception of data. Whether a button is pressed is judged by reading the high and low levels of the pin. The GPIO_ReadInputDataBit() function is used to read the high and low levels of the current pin.

[0052] The following is an example to illustrate the working process of the intelligent sunscreen hat:

[0053] 1. First, turn on the power module 200 of the intelligent sunscreen hat. Press the first control button 301, and the first electromagnetic relay 302 is attracted, and the fan 310 starts to rotate.

[0054] 2. When the first control button 301 is pressed again, the first electromagnetic relay 302 is disconnected, and the fan 310 stops rotating.

[0055] 3. Take the intelligent sunscreen hat outdoors. When the temperature rises and reaches 30 degrees Celsius, the fan 310 starts to rotate automatically.

[0056] 4. Press the second control button 501, and the second electromagnetic relay 502 is attracted, and the lighting lamp 500 is lit.

[0057] 5. Press the second control button 501 again, and the second electromagnetic relay 502 is disconnected, and the lighting lamp 500 goes out.

[0058] 6. Press the third control button 321, and the humidifying sprayer 320 works.

[0059] In this application, a high-precision temperature and humidity IO sensor is adopted: integrating temperature and humidity detection functions, accurately monitoring environmental changes in real time, ensuring the accurate execution of control strategies, and improving the stability and convenience of the user experience.

[0060] And a dual-mode control system is adopted: combining physical switches and intelligent algorithms to achieve flexible control of electronic components. Physical control ensures the stable and reliable basic functions, and intelligent control automatically adjusts according to environmental changes. The dual guarantee improves the stability of the overall system.

[0061] Intelligent voice broadcast technology is adopted: with built-in intelligent judgment logic. When an extremely high-temperature environment is detected, the voice broadcast function is automatically started to remind users to pay attention to preventing heatstroke and reducing the temperature, increasing safety.

[0062] The main controller is an STM32 single-chip microcomputer. A high-performance STM32 single-chip microcomputer is used as the control center to ensure the high efficiency and stability of the equipment operation, ensure the coordinated operation of each functional module, and improve the overall performance.

[0063] In addition, modular design and integration: Mechanical and hardware integration modules are adopted to simplify the control process, reduce the failure rate, and at the same time facilitate maintenance and upgrade to ensure the long-term stable operation of the work.

[0064] Compared with traditional safety helmets, the intelligent sunscreen hat not only guarantees the basic protection function, but also incorporates a number of intelligent and user-friendly designs, greatly improving the user experience and satisfaction.
