Referring to fig. 1, a schematic structural diagram of an intelligent hood 100 according to an embodiment of the present application is provided, the intelligent hood 100 includes a hood body 110 and a hood top 120, the hood top 120 is disposed at the top of the hood body 110 along the extending direction, and a solar panel 130 is further disposed at the top of the hood top 120, and the solar panel 130 is configured to convert solar energy into electric energy to charge a battery pack installed inside the intelligent hood 100.
Further, the intelligent hood 100 further comprises a processor, a rotation speed controller and an axial flow fan, wherein the processor is connected with the solar panel 130 to control the solar panel 130 to charge the battery pack. The processor is further connected with the rotation speed controller to control the axial flow fan to work according to the set rotation speed, so as to provide comfortable air quantity for the wearer of the intelligent blast cap 100 and ensure the experience of the wearer.

Fig. 2 is a schematic flow chart of a control method of an intelligent hood according to an embodiment of the present application, where the method is applied to a processor disposed inside the intelligent hood 100, and the method specifically includes:
s110, when the voltage is lower than a threshold value, detecting and recording the first output power and the first constant current output of the solar panel at the current moment; and according to the second output power of the solar panel at the next moment, compared with the first output power of the solar panel at the current moment, regulating the first constant current output according to a set regulating mechanism so as to determine the maximum power point of the solar panel.
Specifically, the first output power of the solar panel at the current moment is P n-1 ＝Uin n-1 ×Iin n-1 The first constant current is output as Iout n-1 The adjustment mechanism of the setting is α=β× (P n -P n-1 ) Wherein, beta is a control proportion for limiting alpha adjusting intensity, and the second output power of the solar panel at the next moment is P n ＝Uin n ×Iin n The constant current output is Iout n ＝Iout n-1 ×(1+β×(P n -P n-1 ))；
When P n ＞P n-1 When alpha > 0, iout is n >Iout n-1 The constant current output will increase;
when P n <P n-1 When alpha < 0, iout n <Iout n-1 The constant current output will decrease.
By continuously increasing or decreasing the Iout, according to the load volt-ampere characteristic of the solar panel, the current Iout is calculated n ≠Iout n-1 ，P n ≈P n-1 And when the power reaches the peak value, the maximum power point of the solar energy is obtained.
In the embodiment of the application, when the solar panel adopts the glue-dropping solar panel with the illumination intensity of 38000Lux, the maximum output voltage is 6V and the maximum output current is 230mA, but the glue-dropping solar panel is not limited to the glue-dropping solar panel, and the solar panel with other specification parameters can be adopted according to practical situations. According to a large number of experiments, when the solar panel receives certain illumination intensity, the solar panel load volt-ampere characteristic curve is analyzed to find that the output voltage of the solar panel monotonically decreases along with the increase of the output power, and only one maximum power point exists, so that the conversion efficiency of the solar panel can be effectively improved by adjusting the output power of the solar panel in real time to track the maximum power, further, the charging and discharging efficiency of the battery pack is improved, and the cruising ability of the intelligent wind cap 100 is improved. It should be noted that, when the illumination intensity changes greatly or the output voltage of the solar panel decreases sharply, the maximum power point needs to be searched again to ensure the normal operation of the solar panel power supply. Therefore, by the scheme for searching and determining the maximum power point of the solar energy provided by the embodiment of the application, the conversion efficiency of the solar energy can be utilized to a higher degree, and the cruising ability of the intelligent hood 100 is ensured.

Further, the battery pack is a lithium battery pack, and comprises 1 group of main batteries and 2 groups of auxiliary batteries, so that the specific battery number of the lithium battery pack can be flexibly set according to actual needs. Specifically, the solar panel is mainly used for charging the main battery.
Fig. 3 is a schematic connection diagram of a battery pack according to an embodiment of the present application. The main power lithium battery pack is connected to the bus bar by an enhanced PMOS, and the bus bar can be supplied by a body diode. The auxiliary power supply lithium battery pack is connected to the bus by a Schottky diode, and in normal operation, a group of voltage with higher battery voltage is directly supplied to the bus, and when the standby battery is not available, after the PMOS is opened, the auxiliary power supply lithium battery pack can be charged with the main power supply lithium battery pack through the solar panel.
Further, each group is formed by connecting 3 lithium batteries with the capacity reaching 3400mAh in series.
w＝u×i×t
w＝3.7V×3×3400mAh (1)
＝37740mVAh
Wherein w is electric power, u is working voltage, i is working current, t is working time, the rated voltage of the selected 18650 type lithium battery is 3.7V, the full charge voltage is 4.2V, 3.7V is used as working voltage according to the minimum standard calculation, the 3 batteries are connected in series, and the total electric power of each group of lithium batteries is 37740mVAh according to the formula (1).
t＝w÷u÷i＝
37740mAh÷12V÷ (2)
(200mA+50mA)＝12.58h
Wherein t is the duration of discharge, w is the total power, u is the operating voltage, and i is the operating current.
If the system adopts an axial flow fan with rated voltage of 12V and rated current of 200mA, peripheral circuit loss of additional 50mA is removed, when only 1 group of main power supply batteries are installed, the system can be continuously used for 12.58 hours according to the calculation of the formula (2) when the energy converted by solar energy is not calculated. If 2 sets of standby batteries are selected, the sustainable power supply time is about 37 hours. In addition, the solar panel can charge the main battery pack, so that the power supply time can be further prolonged. Therefore, the battery pack provided by the embodiment of the application has longer endurance capacity, and ensures the experience of a wearer.

Specifically, the intelligent hood 100 is further provided with a plurality of sensors at different positions, and the plurality of sensors are used to collect information such as illumination intensity, ambient temperature, human body temperature, and ambient humidity of the current environment. The set gear of the intelligent blast cap 100 is different rotational speed gears of the axial flow fan, and the axial flow fan under different rotational speed gears can output air quantity with different intensities.
And S140, calculating the variables and a preset parameter matrix to obtain the set rotating speed of the axial flow fan.
The specific operation mode is as follows:
in the practical application of the intelligent hood, 5 variables are collected, namely illumination intensity, ambient temperature, human body temperature, ambient humidity and set gear. And then, calculating the variables and the parameters to obtain the rotating speed of the fan, and driving the output air quantity of the axial flow fan to dissipate heat according to the obtained rotating speed of the fan. The parameters can be obtained by collecting a large amount of experimental data, and the process of calculating the parameters and the variables to obtain the set rotating speed of the axial flow fan is as follows:
1. the input control variable X is multiplied by the parameter P to obtain an output Y, as shown in equation 3.
Y＝X·P (3)
2. Equation 3 is equivalent to a matrix as shown in equation 4.
Wherein, the output Y is a matrix and represents the set rotating speed of the output axial flow fan; the input matrix X is a matrix, five elements are respectively represented by illumination intensity, ambient temperature, human body temperature, ambient humidity and set gear, and P is a parameter matrix.
Setting a prototype machine (namely an intelligent wind cap for experiments), wherein the axial flow fan adopts rated 1800RPM, the prototype machine can only select a gear, fine adjustment of the fan rotating speed and record setting, the gear is 3, and each gear is 600RPM. The fine tuning range of the rotational speed is plus or minus 300RPM. Under different use environments, a plurality of volunteers wear the prototype machine, then the gear is adjusted, the rotating speed of the fan is finely adjusted, when the wearer subjectively approves the comfort of wind power, the record setting is pressed, and the processor records the current illumination intensity, the ambient temperature, the ambient humidity, the human body temperature, the gear is set and the rotating speed of the fan is set. For each record, the following parameters are available:
X 1 ＝[l 1 t A1 t H1 h 1 s 1 ]
Y 1 ＝[out 1 ]
… (5)
X n ＝[l n t An t Hn h n s n ]
Y n ＝[out n ]
the equation 5 may be organized into a matrix as shown in equation 6:
equation 7 is obtained from the least squares method of the matrix:
P＝[X T ·X] -1 ·X T ·Y (7)
wherein X is n× 5 An order matrix, i.e. the plurality of variables, Y is an n X1 order matrix, i.e. the predetermined parameter matrix, X T And P is the set rotating speed of the axial flow fan. The set rotation speed obtained by the operation represents most of user habits, and the processor arranged in the intelligent blast cap 100 can also continuously learn the daily use habits of the user, further fit a parameter matrix suitable for the user, obtain the set rotation speed more in line with the user requirements, and improve the user experience.
And S150, when the voltage change of the battery pack exceeds a preset amplitude, controlling the axial flow fan to rotate according to the set rotating speed so as to ensure that the air quantity is constantly output.
That is, when the voltage of the battery pack is greatly changed and exceeds a predetermined range, if the voltage is not regulated and controlled, the axial flow fan is affected by the voltage change, so that the air quantity is obviously changed, and the use experience of a wearer is not facilitated. Therefore, at this time, the processor arranged in the intelligent hood 100 will drive the axial flow fan to rotate according to the set rotation speed, so as to ensure the constant output of the air quantity without affecting the wearer.
On the other hand, when the voltage variation of the battery pack does not exceed the predetermined amplitude, the intelligent hood 100 can directly control the rotation speed of the axial flow fan according to the collected multiple variables to output the air quantity.
Therefore, according to the control method of the intelligent hood, on one hand, the maximum power point of solar energy can be determined to charge the battery pack, solar energy is well utilized, meanwhile, the battery pack has good cruising ability, has a solar energy charging function, and further prolongs the service time of the intelligent hood; on the other hand, the intelligent blast cap can collect a plurality of variables by a plurality of sensors arranged on the inner part and the outer part, and the set rotating speed of the axial flow fan which is comfortable for users in different environments is determined by combining the use habits of a large number of users, so that the stable output air quantity of the axial flow fan is ensured even under the condition of abnormal voltage fluctuation, the experience of the users is better improved, and a more comfortable working environment is provided for high-temperature workers.
