具体实施方式Detailed ways

下面结合具体实施例对本实用新型作进一步说明。The present utility model will be further described below in conjunction with specific embodiments.

图1为本实用新型的便携式智能加湿风扇组成部分示意图,如图1所示,该风扇包括一主控单元,该主控单元具有输入端和输出端;在主控单元的输入端设有温湿度采集模块、热释电检测模块和按键;在主控单元的输出端设有LCD显示屏、电机调速模块、舵机转向模块、继电器、加湿模块以及叶轮。其中,主控单元为STM32单片机;温湿度采集模块将温湿度数值转化成电信号传送至单片机单元,单片机单元根据接收到的湿度信号向继电器发出控制信号;控制加湿器的打开或关闭;单片机单元根据接收到的温度电信号向电机调速模块发出控制信号,控制叶轮作出风速调整;同时,单片机单元将温湿度采集模块的湿度电信号传给LCD显示屏,该LCD显示屏显示出温湿度数值;热释电检测模块将检测到的方位信号发送给单片机单元;单片机单元向舵机转向模块发出控制信号,控制叶轮的摆动。FIG. 1 is a schematic diagram of the components of the portable intelligent humidifying fan of the present invention. As shown in FIG. 1 , the fan includes a main control unit, and the main control unit has an input end and an output end; the input end of the main control unit is provided with a temperature Humidity acquisition module, pyroelectric detection module and buttons; LCD display screen, motor speed control module, steering gear steering module, relay, humidification module and impeller are arranged at the output end of the main control unit. Among them, the main control unit is STM32 single-chip microcomputer; the temperature and humidity acquisition module converts the temperature and humidity values into electrical signals and transmits them to the single-chip unit, and the single-chip unit sends a control signal to the relay according to the received humidity signal; it controls the opening or closing of the humidifier; the single-chip unit According to the received temperature electrical signal, a control signal is sent to the motor speed control module to control the impeller to adjust the wind speed; at the same time, the single-chip unit transmits the humidity electrical signal of the temperature and humidity acquisition module to the LCD display screen, and the LCD display screen displays the temperature and humidity values. The pyroelectric detection module sends the detected azimuth signal to the single-chip unit; the single-chip unit sends a control signal to the steering gear steering module to control the swing of the impeller.

其中,热释电检测模块采用HC-SR501红外热释电传感器,利用人体自身的红外辐射的特性,判断有无人体接近,并确定人体的方位,将检测到的方位信号发送给单片机,单片机再向舵机转向模块发出控制信号,以此实现风扇智能开关和智能摆角控制,极大减少了风扇的摆头空程。从而也实现实时人体追踪功能。Among them, the pyroelectric detection module adopts the HC-SR501 infrared pyroelectric sensor, which uses the characteristics of the human body's own infrared radiation to determine whether there is a human body approaching, and determines the orientation of the human body, and sends the detected orientation signal to the single-chip microcomputer. Send a control signal to the steering gear steering module, so as to realize the intelligent switch and intelligent swing angle control of the fan, which greatly reduces the swing of the fan. Thereby, the real-time human body tracking function is also realized.

为避免加湿器对湿度的测量造成影响,温湿度采集模块对温湿度的采集使用DHT11传感器,形成温湿度当前值的反馈电路,同时,温湿度传感器的安装避开加湿器的位置。加湿模块选用高效率低噪音的超声波加湿器,该加湿器利用水槽底部的换能器将电能转换成机械能,形成超声波,水表面经过空化效应产生水雾,水雾粒子与流动空气进行热湿交换。湿度传感器将检测的湿度信号传送至单片机,单片机判断当前湿度是否在阈值范围内,通过控制继电器的通断来控制加湿器的开关,实现智能加湿并起到降温作用。In order to avoid the influence of the humidifier on the humidity measurement, the temperature and humidity acquisition module uses the DHT11 sensor to collect the temperature and humidity to form a feedback circuit for the current value of the temperature and humidity. At the same time, the installation of the temperature and humidity sensor avoids the location of the humidifier. The humidification module uses an ultrasonic humidifier with high efficiency and low noise. The humidifier uses the transducer at the bottom of the water tank to convert electrical energy into mechanical energy to form ultrasonic waves. exchange. The humidity sensor transmits the detected humidity signal to the single-chip microcomputer, and the single-chip computer judges whether the current humidity is within the threshold range, and controls the switch of the humidifier by controlling the on-off of the relay, realizing intelligent humidification and cooling.

如图2所示,本实用新型的便携式智能加湿风扇的工作原理如下:As shown in Figure 2, the working principle of the portable intelligent humidifying fan of the present invention is as follows:

接通电源后,便携式智能加湿风扇启动,首先对STM32系统、DHT11温湿度传感器进行初始化,对LCD显示屏进行初始化与清屏操作。初始化完成后,通过温湿度传感器DHT11获取当前的温湿度数值转化成电信号传送至单片机,并通过LCD显示屏显示出当前的温度和湿度数值。After the power is turned on, the portable intelligent humidification fan starts. First, the STM32 system and the DHT11 temperature and humidity sensor are initialized, and the LCD display is initialized and cleared. After the initialization is completed, the current temperature and humidity values obtained through the temperature and humidity sensor DHT11 are converted into electrical signals and transmitted to the microcontroller, and the current temperature and humidity values are displayed through the LCD display.

完成了开机初始化及当前环境温湿度值的显示工作后,单片机单元开始进行工作模式的判断,通过检测是否有按键输入,来确定该系统工作在手动模式或智能模式。After completing the power-on initialization and the display of the current ambient temperature and humidity values, the single-chip unit starts to judge the working mode, and determines whether the system works in the manual mode or the intelligent mode by detecting whether there is a key input.

当检测到有按键输入时,系统处于手动模式,此时通过识别用户的输入值来确定恒定的风速、叶轮方向及湿度。When a key input is detected, the system is in manual mode, and the constant wind speed, impeller direction and humidity are determined by identifying the user's input value.

当检测到无按键输入时,系统则进入智能模式。首先判断有无红外信号进入风扇工作范围内。当人体红外热释电传感器探测到有人体进入测量范围7M以内时,风轮开启;同时确定人体的方位,将检测到的方位信号发送给单片机,单片机再向转向模块发出控制信号,舵机工作,控制叶轮的方向转动。若检测到同时有多个方位的人体信号时,则开启固定摆头模式,直至红外感应的范围内只有一个人体方位信号时开启智能人体追踪。若未检测到人体进入,风扇休眠,停止当前工作。When no key input is detected, the system enters the smart mode. First, determine whether there is an infrared signal entering the working range of the fan. When the human body infrared pyroelectric sensor detects that there is a human body entering the measurement range within 7M, the wind wheel is turned on; at the same time, the orientation of the human body is determined, and the detected orientation signal is sent to the single-chip microcomputer, and the single-chip microcomputer sends a control signal to the steering module, and the steering gear works , which controls the direction of the impeller. If a human body signal with multiple orientations is detected at the same time, the fixed head swing mode is turned on, and the intelligent human body tracking is turned on until there is only one human body orientation signal within the range of infrared sensing. If no human body is detected, the fan will sleep and stop the current work.

风扇叶轮的转速设为低、中、高三个档,分别对应温度阈值为20℃、25℃、30℃。单片机判断当前接收到的温度信号分别处于何种阈值范围内,作出风速调整。The speed of the fan impeller is set to three gears: low, medium and high, corresponding to the temperature thresholds of 20°C, 25°C, and 30°C respectively. The single-chip computer determines which threshold range the currently received temperature signal is in, and adjusts the wind speed.

湿度的阈值设定为40%,当系统检测到湿度未达标时将自动向继电器输出信号,打开加湿器,达到70%时自动停止,以将湿度维持在符合人体舒适度的范围内。The humidity threshold is set to 40%. When the system detects that the humidity is not up to the standard, it will automatically output a signal to the relay, turn on the humidifier, and automatically stop when it reaches 70%, so as to maintain the humidity within the range that is in line with human comfort.

当温湿度、转向都调整完成后,风扇延时,工作在当前状态,并重新进行温湿度采集,获取实时的温湿度值,不断做出相应调整。When the adjustment of temperature and humidity and steering is completed, the fan delays and works in the current state, and re-collects temperature and humidity to obtain real-time temperature and humidity values, and continuously makes corresponding adjustments.

该实用新型的智能加湿风扇真正实现了风扇智能化,与普通风扇相比,实现了识别人体自动开启,转向追踪;并根据温度自动调节风速,根据湿度调节加湿器的开关。The intelligent humidifying fan of the utility model truly realizes the intelligentization of the fan. Compared with the ordinary fan, it realizes the automatic opening of the human body recognition and the steering tracking; the wind speed is automatically adjusted according to the temperature, and the switch of the humidifier is adjusted according to the humidity.
