In addition, generally, the touring cap is usually used for shading, a user needs to consider the shading function firstly and consider the heat dissipation function secondly, when the ambient light intensity is smaller than a preset light intensity threshold value, the user is determined not to have the requirement of shading, the heat dissipation and cooling effect caused by taking off the cap is far stronger than the blowing effect of the small fan, even if the ambient temperature is larger than the preset temperature threshold value, the user can generally select to take off the cap without opening the small fan, therefore, the embodiment can judge whether the user has the requirement of using the touring cap or not by detecting the ambient light intensity, the forehead can sweat when the temperature of the head of the user possibly rises, and the fan is closed when the user does not need to use the touring cap, so that the user is guided to take off the cap and selects to take off the cap to dissipate heat and cool, the design is more humanized and more close to practical application, and the practicability is stronger.

When the tour hat is idle, the tour hat is easy to be affected with damp if the environment humidity is too high. In this embodiment, ambient humidity is greater than predetermineeing first humidity value, and it is too big to represent ambient humidity, leads to the tourist cap to wet easily, and infrared detection unit does not discern infrared radiation, represents the user and does not use the tourist cap this moment, can control the heat band like this and heat the tourist cap under the prerequisite of confirming the user does not use the tourist cap for the evaporation of steam on the tourist cap avoids the tourist cap to wet.

Generally, in a transition season, the change range of the environmental temperature within a certain time is large, and the travel cap is easy to be affected with damp. In the embodiment, the maximum temperature difference of the ambient temperature within the preset first time value is not less than the preset first temperature value, which means that the variation range of the ambient temperature within a certain time is large at the moment, the travel cap is easy to damp, the heating belt can be controlled to heat the travel cap on the premise that the user does not use the travel cap, the evaporation of water vapor on the travel cap is accelerated, and the travel cap is prevented from being damp; and the function of preventing the tour hat from being affected with damp is further improved by detecting the environmental temperature.
Optionally, the first humidity value is 60%, and the first temperature value is 5 ℃.
Optionally, as shown in fig. 2, the light intensity detecting unit of the present embodiment includes a photodetector, a pre-amplification module, an AD conversion module, and a range conversion module; the photoelectric detector is used for detecting the illumination intensity of the environment and converting the light intensity signal into a photocurrent signal; the input end of the pre-amplification module is connected with the output end of the photoelectric detector, and the pre-amplification module is used for converting the photocurrent signal into a voltage signal and amplifying the voltage signal; the input end of the AD conversion module is connected with the output end of the pre-amplification module, and the output end of the AD conversion module is connected with the central control unit; the range conversion module is respectively connected with the pre-amplification module and the central control unit and is used for changing the gain of the pre-amplification module by changing the range of the range conversion module; the central control unit is also used for controlling the range conversion module to change the gain of the pre-amplification module when the output of the pre-amplification module is higher than the input upper limit of the AD conversion module or lower than the input lower limit of the AD conversion module until the output of the pre-amplification module is between the input lower limit and the input upper limit. And the digital signal output by the AD conversion module is transmitted to the central control unit, and the central control unit calculates the indoor illumination intensity according to the output of the AD conversion module.
Generally, because an optical signal output by a photodetector is usually weak, interference of various noises directly affects measurement accuracy of a useful signal, and both resolution and measurement range need to be considered during measurement, which requires a reasonable design of a pre-amplification module connected with the detector to obtain a large dynamic range and a high signal-to-noise ratio. Most of the existing light intensity signal amplification modules only pursue high gain, but neglect the consideration of measurement range, and have the problems of temperature drift, noise increase, offset voltage large and the like, which can not meet the practical application requirements of the light intensity detection system.
In this embodiment, after the module is powered on, the range conversion module automatically sets the range to the highest level, that is, the gain of the preamplifier module is the largest, and the AD conversion module reads the output voltage of the preamplifier module once every certain period of time to perform over-range or under-range determination. The judgment standard takes 95% of the maximum value of the measurement range of the AD conversion module as the input upper limit, takes 10% of the minimum value of the measurement range of the AD conversion module as the input lower limit, the output voltage of the pre-amplification module is over-range when being higher than the input upper limit, and the output voltage of the pre-amplification module is under-range when being lower than the input lower limit. If the output voltage of the pre-amplification module is between the input lower limit and the input upper limit, the central control unit outputs the program control signal to control the range of the range conversion module to change from high to low until the output voltage of the pre-amplification module is between the input lower limit and the input upper limit. If the current measuring range is not suitable after the input optical power is changed, the module automatically determines the increase and decrease of the measuring range according to the change trend of the input optical power until the measuring range is suitable again. Therefore, the light intensity detection unit of the embodiment can automatically adjust the gain of the pre-amplification module according to the output voltage of the pre-amplification module so as to enable the output voltage of the pre-amplification module to be within the measuring range of the AD conversion module, has the advantages of low noise, high gain, high common mode rejection ratio, small misadjustment, large dynamic range of detectable light intensity and the like, and can meet the actual application requirement of light intensity detection.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
