一、智能家居项目框架设计草图

 代码思路讲解：

1、一个指令工厂，一个控制工厂，实际上就是通过链表链起来的数据。具体怎么链接起来，就是基于简单工厂模式的类与对象的概念，上一篇文章有学习记录。
2、主函数语音指令程序和tcp指令程序各起一个线程，然后通过指令名字找到对应的控制程序，实现对应的模块的功能。

二、框架代码文件工程建立

1、在桌面新建一个项目文件夹smartHose,然后在文件夹中创建如下文件：

2、把上述的所有文件，都加载到Source lnsight工具中，如下图代表加载完毕

3、创建inputCommand.h头文件

//面向指令工厂的头文件
#include <wiringPi.h>
#include <stdlib.h>

struct InputCommander{

	char commandName[128];             //名字
	char command[32];                  //指令
	int (*Init)(char *name,char *ipAdress,char *port);  //操作函数 
	int (*getCommand)(char *cmd);      //获取数据函数

	char log[1024];                    //log日志获取
	struct InputCommander *next;
};

4、创建contrlDevices.h头文件

//设备头文件
#include <wiringPi.h>

struct Devices{

	char deviceName[128]; //名字
	int status;           //状态
	int pinNum;           //引脚
	
	int (*open)(int pinNum);        //打开
	int (*close)(int pinNum);       //关闭
	int (*deviceInit)(int pinNum);  //设备初始化

	int (*readStatus)();  //火灾
	int (*changeStatus)(int status);

	struct Devices *next;
};

struct Devices* addBathroomLightToDeviceLink(struct Devices *phead);
struct Devices* addUpstairLightToDeviceLink(struct Devices *phead);
struct Devices* addLivingRoomLightToDeviceLink(struct Devices *phead);
struct Devices* addRestaurantLightToDeviceLink(struct Devices *phead);
struct Devices* addFireToDeviceLink(struct Devices *phead);

5、创建bathroomLight.c文件

//浴室的灯
#include "contrlDevices.h"
#include<stdlib.h>

int bathroomLightOpen(int pinNum){

	digitalWrite(pinNum,LOW);
}
int bathroomLightClose(int pinNum){

	digitalWrite(pinNum,HIGH);
}
int bathroomLightCloseInit(int pinNum){

	pinMode(pinNum,OUTPUT);
	digitalWrite(pinNum,HIGH);
}
int bathroomLightCloseStatus(int status){

}
struct Devices bathroomLight={
	
	.deviceName = "bathroomLight",
	.pinNum = 26,
	.open = bathroomLightOpen,
	.close = bathroomLightClose,
	.deviceInit = bathroomLightCloseInit,
	.changeStatus = bathroomLightCloseStatus
	
};
struct Devices* addBathroomLightToDeviceLink(struct Devices *phead){

	if(phead == NULL){	
		return &bathroomLight;
	}
	else{
		bathroomLight.next = phead;
		phead = &bathroomLight;
	}
};

6、创建livingroomLight.c文件

#include "contrlDevices.h"
#include<stdlib.h>

int livingroomLightOpen(int pinNum){

	digitalWrite(pinNum,LOW);
}
int livingroomLightClose(int pinNum){

	digitalWrite(pinNum,HIGH);
}
int livingroomLightCloseInit(int pinNum){

	pinMode(pinNum,OUTPUT);
	digitalWrite(pinNum,HIGH);
}
int livingroomLightCloseStatus(int status){

}
struct Devices livingroomLight={
	
	.deviceName = "livingroomLight",
	.pinNum = 27,
	.open = livingroomLightOpen,
	.close = livingroomLightClose,
	.deviceInit = livingroomLightCloseInit,
	.changeStatus = livingroomLightCloseStatus
	
};
struct Devices* addLivingRoomLightToDeviceLink(struct Devices *phead){
	if(phead == NULL){	
		return &livingroomLight;
	}
	else{
		livingroomLight.next = phead;
		phead = &livingroomLight;
	}
};

7、创建restaurantLight.c文件

#include "contrlDevices.h"
#include<stdlib.h>

int restaurantLightOpen(int pinNum){

	digitalWrite(pinNum,LOW);
}
int restaurantLightClose(int pinNum){

	digitalWrite(pinNum,HIGH);
}
int restaurantLightCloseInit(int pinNum){

	pinMode(pinNum,OUTPUT);
	digitalWrite(pinNum,HIGH);
}
int restaurantLightCloseStatus(int status){

}
struct Devices restaurantLight={
	
	.deviceName = "restaurantLight",
	.pinNum = 28,
	.open = restaurantLightOpen,
	.close = restaurantLightClose,
	.deviceInit = restaurantLightCloseInit,
	.changeStatus = restaurantLightCloseStatus
};
struct Devices* addRestaurantLightToDeviceLink(struct Devices *phead){

	if(phead == NULL){	
		return &restaurantLight;
	}
	else{
		restaurantLight.next = phead;
		phead = &restaurantLight;
	}
};

8、创建upstairLight.c文件

//二楼灯
#include "contrlDevices.h"
#include<stdlib.h>

int upstairLightOpen(int pinNum){

	digitalWrite(pinNum,LOW);
}
int upstairLightClose(int pinNum){

	digitalWrite(pinNum,HIGH);
}
int upstairLightCloseInit(int pinNum){

	pinMode(pinNum,OUTPUT);
	digitalWrite(pinNum,HIGH);
}
int upstairLightCloseStatus(int status){

}
struct Devices upstairLight={
	
	.deviceName = "upstairLight",
	.pinNum = 29,
	.open = upstairLightOpen,
	.close = upstairLightClose,
	.deviceInit = upstairLightCloseInit,
	.changeStatus = upstairLightCloseStatus
};
struct Devices* addUpstairLightToDeviceLink(struct Devices *phead){

	if(phead == NULL){	
		return &upstairLight;
	}
	else{
		upstairLight.next = phead;
		phead = &upstairLight;
	}
};

9、创建fire.c文件

//火灾报警
#include "contrlDevices.h"
#include<stdlib.h>

int fireIfOrNotInit(int pinNum){

	pinMode(pinNum,INPUT);
	digitalWrite(pinNum,HIGH);
}
int fireStatusRead(int pinNum){

	return digitalRead(pinNum);
}
struct Devices fireIfOrNot={
	
	.deviceName = "fireIfOrNot",
	.pinNum = 25,
	.deviceInit = fireIfOrNotInit,
	.readStatus = fireStatusRead
	
};
struct Devices* addFireToDeviceLink(struct Devices *phead){

	if(phead == NULL){	
		return &fireIfOrNot;
	}
	else{
		fireIfOrNot.next = phead;
		phead = &fireIfOrNot;
	}
};

10、创建mainPro.c主函数文件

#include <stdio.h>
#include "contrlDevices.h"
#include <string.h>
#include "inputCommand.h"

struct Devices* findDeviceByName(char* name,struct Devices* phead){

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

int main(){

	char name [128];
	struct Devices *tmp = NULL;
	if(-1 == wiringPiSetup()){
		return -1;
	}
	struct Devices *pdeviceHead = NULL;
	pdeviceHead = addBathroomLightToDeviceLink(pdeviceHead);
	pdeviceHead = addUpstairLightToDeviceLink(pdeviceHead);
	pdeviceHead = addLivingRoomLightToDeviceLink(pdeviceHead);
	pdeviceHead = addRestaurantLightToDeviceLink(pdeviceHead);
	pdeviceHead = addFireToDeviceLink(pdeviceHead);
	
	while(1){

		printf("Input:\n");
		scanf("%s",name);
		tmp = findDeviceByName(name,pdeviceHead);
		
		if(tmp != NULL){
			tmp->deviceInit(tmp->pinNum);
			tmp->open(tmp->pinNum);
		}
	}
	//1、指令工厂初始化
	//2、设备控制工厂初始化
	//3、线程池建立
	//3.1、语音线程
	//3.2、socket线程
	//3.3、摄像头线程
	//3.4、火灾线程
}

把上述的代码传到树莓派的终端，用FileZilla传即可，然后执行结果：

gcc mainPro.c upstairLight.c bathroomLight.c livingroomLight.c restaurantLight.c -lwiringPi -o test1

效果演示：（虽然没有装到实际的智能家居里，但是小灯亮了，说明程序是可以正常用的🤭）

三、添加声音识别模块的串口读取功能

这里主要通过主控芯片树莓派的串口跟语音模块连接。
树莓派的T接语音模块的R
树莓派的R接语音模块的T
然后就是供电

我们先把语音模块的代码整合到指令链表当中去：
1.语音控制设备voiceContrl.c

#include "inputCommand.h"
#include <stdlib.h>
#include <wiringPi.h>
#include <stdio.h>
#include <wiringSerial.h>
#include <unistd.h>

//串口

int voiceInit(struct InputCommander *voicer,char *ipAdress,char *port){ //声音初始化

	int fd;
	if((fd = serialOpen(voicer->deviceName,9600)) == -1){  //初始化串口，波特率9600
			exit(-1);
	}
	voicer->fd = fd;
	return fd;
} 
int voiceGetCommand(struct InputCommander *voicer){

	int nread = 0;
	nread = (voicer->fd,voicer->command,sizeof(voicer->command));
	if(nread == 0){
		printf("usart for voice read over time\n");
	}else{
		return nread;
	}
}
struct InputCommander voiceContrl = {

	.commandName = "voice", 
	.deviceName = "dev/ttyAMA0",
	.command = {'\0'},
	.Init = voiceInit,
	.getCommand = voiceGetCommand,
	.log = {'\0'},
	.next = NULL,

};
struct InputCommander* addvoiceContrlToInputCommandLink(struct InputCommander *phead){

	if(phead == NULL){
		return &voiceContrl;
	}
	else{
		voiceContrl.next = phead;
		phead = &voiceContrl;
	}
};

2.控制设备的头文件inputCommand.h

//面向指令工厂的头文件
#include <wiringPi.h>
#include <stdlib.h>

struct InputCommander{

	char commandName[128];  //声音的名字
	char command[32];       
	char deviceName[128];   //串口的名字
	int (*Init)(struct InputCommander *voicer,char *ipAdress,char *port); 
	int (*getCommand)(struct InputCommander *voicer);

	char log[1024];
	int fd;
	struct InputCommander *next;

};
struct InputCommander* addvoiceContrlToInputCommandLink(struct InputCommander *phead);

3.在mainPro.c主函数中添加语音模块的函数

#include <stdio.h>
#include "contrlDevices.h"
#include <string.h>
#include "inputCommand.h"

struct Devices* findDeviceByName(char* name,struct Devices* phead){

	struct Devices *tmp = phead;
	if(phead == NULL){
		return NULL;
	}
	else{
		while(tmp != NULL){
			if(strcmp(tmp->deviceName,name) == 0){
				return tmp;
			}
			tmp = tmp->next;
		}
		return NULL;
	}
};
int main(){

	char name [128];
	struct Devices *tmp = NULL;
	if(-1 == wiringPiSetup()){
		return -1;
	}
	struct Devices        *pdeviceHead = NULL;   //设备工厂
	struct InputCommander *pCommandHead = NULL;  //指令工厂
		
	pdeviceHead = addBathroomLightToDeviceLink(pdeviceHead);
	pdeviceHead = addUpstairLightToDeviceLink(pdeviceHead);
	pdeviceHead = addLivingRoomLightToDeviceLink(pdeviceHead);
	pdeviceHead = addRestaurantLightToDeviceLink(pdeviceHead);
	pdeviceHead = addFireToDeviceLink(pdeviceHead);  //火灾

	pCommandHead = addvoiceContrlToInputCommandLink(pCommandHead); //串口
	while(1){

		printf("Input:\n");
		scanf("%s",name);
		tmp = findDeviceByName(name,pdeviceHead);
		
		if(tmp != NULL){
			tmp->deviceInit(tmp->pinNum);
			tmp->open(tmp->pinNum);
		}
	}
}

4.把上述的代码传到树莓派的终端，用FileZilla传即可，然后执行结果：

gcc mainPro.c upstairLight.c bathroomLight.c fire.c livingroomLight.c restaurantLight.c voiceContrl.c -lwiringPi -o test1
