一、智能家居项目框架设计草图

 代码思路讲解：

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

1.  
   //面向指令工厂的头文件
2.  
   #include <wiringPi.h>
3.  
   #include <stdlib.h>
4.  
    
5.  
   struct InputCommander{
6.  
    
7.  
   char commandName[128]; //名字
8.  
   char command[32]; //指令
9.  
   int (*Init)(char *name,char *ipAdress,char *port); //操作函数
10.  
    int (*getCommand)(char *cmd); //获取数据函数
11.  
     
12.  
    char log[1024]; //log日志获取
13.  
    struct InputCommander *next;
14.  
    };

4、创建contrlDevices.h头文件

1.  
   //设备头文件
2.  
   #include <wiringPi.h>
3.  
    
4.  
   struct Devices{
5.  
    
6.  
   char deviceName[128]; //名字
7.  
   int status; //状态
8.  
   int pinNum; //引脚
9.  
    
10.  
    int (*open)(int pinNum); //打开
11.  
    int (*close)(int pinNum); //关闭
12.  
    int (*deviceInit)(int pinNum); //设备初始化
13.  
     
14.  
    int (*readStatus)(); //火灾
15.  
    int (*changeStatus)(int status);
16.  
     
17.  
    struct Devices *next;
18.  
    };
19.

8.  
   }
9.  
   int upstairLightClose(int pinNum){
10.  
     
11.  
    digitalWrite(pinNum,HIGH);
12.  
    }
13.  
    int upstairLightCloseInit(int pinNum){
14.  
     
15.  
    pinMode(pinNum,OUTPUT);
16.  
    digitalWrite(pinNum,HIGH);

    };

9、创建fire.c文件

1.  
   //火灾报警
2.  
   #include "contrlDevices.h"

    return digitalRead(pinNum);
13.  
    }
14.  
    struct Devices fireIfOrNot={

16.  
    .deviceName = "fireIfOrNot",
17.  
    .pinNum = 25,
18.  
    .deviceInit = fireIfOrNotInit,
19.  
    .readStatus = fireStatusRead
20.  
     
21.  
    };
22.  
    struct Devices* addFireToDeviceLink(struct Devices *phead){
23.  
     
24.  
    if(phead == NULL){
25.  
    return &fireIfOrNot;
26.  
    }
27.  
    else{

    fireIfOrNot.next = phead;
29.  
    phead = &fireIfOrNot;
30.  
    }
31.  
    };

10、创建mainPro.c主函数文件

1.  
   #include <stdio.h>
2.  
   #include "contrlDevices.h"
3.  
   #include <string.h>
4.  
   #include "inputCommand.h"
5.  
    
6.  
   struct Devices* findDeviceByName(char* name,struct Devices* phead){
7.  
    
8.  
   struct Devices *tmp = phead;
9.  
   if(phead == NULL){
10.  
    return NULL;
11.  
    }
12.  
    else{
13.  
    while(tmp != NULL){
14.  
    if(strcmp(tmp->deviceName,name) == 0){
15.  
    return tmp;
16.  
    }
17.  
    tmp = tmp->next;
18.  
    }
19.  
    return NULL;
20.  
    }
21.  
    };
22.  
     
23.  
    int main(){
24.  
     
25.  
    char name [128];
26.  
    struct Devices *tmp = NULL;
27.  
    if(-1 == wiringPiSetup()){
28.  
    return -1;
29.  
    }
30.  
    struct Devices *pdeviceHead = NULL;
31.  
    pdeviceHead = addBathroomLightToDeviceLink(pdeviceHead);
32.  
    pdeviceHead = addUpstairLightToDeviceLink(pdeviceHead);
33.  
    pdeviceHead = addLivingRoomLightToDeviceLink(pdeviceHead);
34.  
    pdeviceHead = addRestaurantLightToDeviceLink(pdeviceHead);
35.  
    pdeviceHead = addFireToDeviceLink(pdeviceHead);
36.  
     
37.  
    while(1){
38.  
     
39.  
    printf("Input:\n");
40.  
    scanf("%s",name);
41.  
    tmp = findDeviceByName(name,pdeviceHead);
42.  
     
43.  
    if(tmp != NULL){
44.  
    tmp->deviceInit(tmp->pinNum);
45.  
    tmp->open(tmp->pinNum);
46.  
    }
47.  
    }
48.  
    //1、指令工厂初始化
49.  
    //2、设备控制工厂初始化
50.  
    //3、线程池建立
51.  
    //3.1、语音线程
52.  
    //3.2、socket线程
53.  
    //3.3、摄像头线程
54.  
    //3.4、火灾线程
55.  
    }

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

1.  
   #include "inputCommand.h"
2.  
   #include <stdlib.h>
3.  
   #include <wiringPi.h>
4.  
   #include <stdio.h>
5.  
   #include <wiringSerial.h>
6.  
   #include <unistd.h>
7.  
    
8.  
   //串口
9.  
    
10.  
    int voiceInit(struct InputCommander *voicer,char *ipAdress,char *port){ //声音初始化
11.  
     
12.  
    int fd;
13.  
    if((fd = serialOpen(voicer->deviceName,9600)) == -1){ //初始化串口，波特率9600
14.  
    exit(-1);
15.  
    }
16.  
    voicer->fd = fd;
17.  
    return fd;
18.  
    }
19.  
    int voiceGetCommand(struct InputCommander *voicer){
20.  
     
21.  
    int nread = 0;
22.  
    nread = (voicer->fd,voicer->command,sizeof(voicer->command));
23.  
    if(nread == 0){
24.  
    printf("usart for voice read over time\n");
25.  
    }else{
26.  
    return nread;
27.  
    }
28.  
    }
29.  
    struct InputCommander voiceContrl = {
30.  
     
31.  
    .commandName = "voice",
32.  
    .deviceName = "dev/ttyAMA0",
33.  
    .command = {'\0'},
34.  
    .Init = voiceInit,
35.  
    .getCommand = voiceGetCommand,
36.  
    .log = {'\0'},
37.  
    .next = NULL,
38.  
     
39.  
    };
40.  
    struct InputCommander* addvoiceContrlToInputCommandLink(struct InputCommander *phead){
41.  
     
42.  
    if(phead == NULL){
43.  
    return &voiceContrl;
44.  
    }
45.  
    else{
46.  
    voiceContrl.next = phead;
47.  
    phead = &voiceContrl;
48.  
    }
49.  
    };

2.控制设备的头文件inputCommand.h

1.  
   //面向指令工厂的头文件
2.  
   #include <wiringPi.h>
3.  
   #include <stdlib.h>
4.  
    
5.  
   struct InputCommander{
6.  
    
7.  
   char commandName[128]; //声音的名字
8.  
   char command[32];
9.  
   char deviceName[128]; //串口的名字
10.  
    int (*Init)(struct InputCommander *voicer,char *ipAdress,char *port);
11.  
    int (*getCommand)(struct InputCommander *voicer);
12.  
     
13.  
    char log[1024];
14.  
    int fd;
15.  
    struct InputCommander *next;
16.  
     
17.  
    };
18.  
    struct InputCommander* addvoiceContrlToInputCommandLink(struct InputCommander *phead);

3.在mainPro.c主函数中添加语音模块的函数

1.  
   #include <stdio.h>
2.  
   #include "contrlDevices.h"
3.  
   #include <string.h>
4.  
   #include "inputCommand.h"
5.  
    
6.  
   struct Devices* findDeviceByName(char* name,struct Devices* phead){
7.  
    
8.  
   struct Devices *tmp = phead;
9.  
   if(phead == NULL){
10.  
    return NULL;
11.  
    }
12.  
    else{
13.  
    while(tmp != NULL){
14.  
    if(strcmp(tmp->deviceName,name) == 0){
15.  
    return tmp;
16.  
    }
17.  
    tmp = tmp->next;
18.  
    }
19.  
    return NULL;
20.  
    }
21.  
    };
22.  
    int main(){
23.  
     
24.  
    char name [128];
25.  
    struct Devices *tmp = NULL;
26.  
    if(-1 == wiringPiSetup()){
27.  
    return -1;
28.  
    }
29.  
    struct Devices *pdeviceHead = NULL; //设备工厂
30.  
    struct InputCommander *pCommandHead = NULL; //指令工厂
31.  
     
32.  
    pdeviceHead = addBathroomLightToDeviceLink(pdeviceHead);
33.  
    pdeviceHead = addUpstairLightToDeviceLink(pdeviceHead);
34.  
    pdeviceHead = addLivingRoomLightToDeviceLink(pdeviceHead);
35.  
    pdeviceHead = addRestaurantLightToDeviceLink(pdeviceHead);
36.  
    pdeviceHead = addFireToDeviceLink(pdeviceHead); //火灾
37.  
     
38.  
    pCommandHead = addvoiceContrlToInputCommandLink(pCommandHead); //串口
39.  
    while(1){
40.  
     
41.  
    printf("Input:\n");
42.  
    scanf("%s",name);
43.  
    tmp = findDeviceByName(name,pdeviceHead);
44.  
     
45.  
    if(tmp != NULL){
46.  
    tmp->deviceInit(tmp->pinNum);
47.  
    tmp->open(tmp->pinNum);
48.  
    }
49.  
    }
50.  
    }

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
