智能除湿器项目说明

除湿器原理

知识点

GPIO、定时器、中断、ADC、LCD屏幕、SHT20、SPI、IIC、UART

功能概述

模块

功能

LCD屏幕

显示温湿度,风机开关情况,制冷⽚开关情况,加热片开关情况,温湿度上下阈值,设备ID,电池电压

LED\风扇

两个灯分别模拟制冷片(LED1),加热片(LED3)(灯亮表示开,灯灭表示关),风扇模拟风机

SHT20

温湿度传感器

内部

电池电压采集

串口

数据接收及下发数据控制

控温模式

当环境温度低于设置的阈值时,加热片启动。加热到温度阈值加2摄氏度停

当环境温度高于设置的阈值时,风机冷凝片启动。降温到温度阈值减2摄氏度停

除湿模式

当环境湿度高于设置的阈值时,风机冷凝片加热片启动。湿度低于设置的阈值停

按键

按键控制当前的温湿度阈值和调节当前模式

底板USER按键、拓展板KEY1\KEY2\KEY3均可用

基本要求

除湿器上电设备自检(有电池电压检测,有电压正常无电压异常),⾃检通过后进入自动模式

LCD显示温湿度,风机开关情况,制冷⽚开关情况,加热片开关情况,温湿度上下阈值,设备ID,电池电压。

通过按键选择模式并调整温湿度的阈值大小。

与上位机通信(串口助手),每2s发送设备状态信息到上位机。上位机可发送命令设置除湿器(这里需要识别设备ID),上位机可发送指令获取设备状态信息。

思路

项目实现

上电自检

复位后,ADC转换一次进行上电自检,通过后显示自检通过动画,开机动画,并默认进入自动模式

  ILI9341_Init(); //LCD初始化
//上拉自检//启动adc转换HAL_ADC_Start(&hadc4);HAL_ADC_PollForConversion(&hadc4,100);    //等待转换完成,第二个参数表示超时时间,单位msval=HAL_ADC_GetValue(&hadc4);   //获取ADC转换结果Vbat=(val*3.3*4)/4095;if(Vbat>3){		HAL_TIM_Base_Start_IT(&htim2); //开启定时USART1_RxCounter = 0;	 //中断标志位初始化SystemSelfTest();	//自检通过动画LCD_Picture2(); //开机动画LCD_Picture(gImage_2); //背景/* USER CODE END 2 *//* Infinite loop *//* USER CODE BEGIN WHILE */while (1){}
//开机自检通过动画
void SystemSelfTest() 
{  Gui_DrawFont_GBK16(10, 30, RED,BLACK, (uint8_t *)"Vbat OK");HAL_Delay(500);Gui_DrawFont_GBK16(10, 50, RED,BLACK, (uint8_t *)"Fan OK");HAL_Delay(500);Gui_DrawFont_GBK16(10, 70, RED,BLACK, (uint8_t *)"Condenser OK");HAL_Delay(500);Gui_DrawFont_GBK16(10, 90, RED,BLACK, (uint8_t *)"Heater OK");HAL_Delay(500);ILI9341_Clear(BLACK);
}

自检失败,显示失败信息并蓝屏

else{SystemSelfTest_Fail();	Gui_DrawFont_GBK16(40, 150, WHITE,BLUE, (uint8_t *)"The self-test failed");		}
//自检失败动画
void SystemSelfTest_Fail() 
{  Gui_DrawFont_GBK16(10, 30, RED,BLACK, (uint8_t *)"Vbat Fail");Gui_DrawFont_GBK16(10, 50, RED,BLACK, (uint8_t *)"Fan Fail");Gui_DrawFont_GBK16(10, 70, RED,BLACK, (uint8_t *)"Condenser Fail");Gui_DrawFont_GBK16(10, 90, RED,BLACK, (uint8_t *)"Heater Fail");HAL_Delay(1000);ILI9341_Clear(BLUE);
}
