树莓派——linux智能家居_基于linux的智能家居系统

一、需求：

       主控芯片——树莓派

        控制端支持语音设备的输入uart，也可以是安卓app（tcp客户端）

        外设——灯：客厅灯、餐厅灯、二楼灯、卫生间灯；

                      火灾报警器

                        摄像头：监控、人脸锁

                        433M：泳池灯、实景智能窗帘

                        红外——电风扇、电视、空调、小夜灯

如下图，一边是指令工厂、一边是控制工厂，main函数负责组织架构

1、树莓派控制灯的实现

接线：灯的接线，orangepi2、5、7、8接4联继电器1，2，3，4，

                                客厅——2

                                餐厅——5脚

                                卫生间灯——7脚，

                                二楼灯——8脚，

代码：

#include <stdio.h>
#include <string.h>
#include "controlDevices.h"

		return NULL;
	}else{
		while(tmp!=NULL){
			if(strcmp(tmp->deviceName,name)==0){
				return tmp;
			}
			tmp=tmp->next;
		}
	}
}

	char name[32];
	struct Devices *tmp=NULL;
	
	if(wiringPiSetup()==-1)
		return -1;

	pdeviceHead=addupstairLightToDeviceLink(pdeviceHead);
	pdeviceHead=addresturantLightToDeviceLink(pdeviceHead);
	pdeviceHead=addlivingroomLightToDeviceLink(pdeviceHead);
 
	while(1){
		printf("你想要点亮哪盏灯\n");
		scanf("%s",name);
 
		tmp= findDeviceByName(name,pdeviceHead);
		if(tmp!=NULL){
			tmp->deviceInit(tmp->pinNum);
			tmp->close(tmp->pinNum);//这里控制打开和关闭，关闭是close，打开是open
		}
	}
	//1.指令工厂初始化
 
	//2.设备工厂初始化
 
	//3.线程池建立
		//3.1语音线程
		//3.2socket线程
		//3.3摄像头线程
		//3.4火灾线程
	return 0;
