智能家居(4)---火灾报警线程封装

封装火灾报警线程实现智能家居中的火灾报警功能 mainPro.c（主函数）

#include

#include "controlDevice.h"

#include "inputCommand.h"

#include

struct Devices *pdeviceHead = NULL; //设备工厂链表头

struct Devices* findDeviceByName(struct Devices *phead,char *name) //在设备链表中查找设备（语音和socket均可使用）

{

struct Devices *tmp = phead;

if(tmp == NULL){

printf("The devicesLink is NULL");

return NULL;

}else{

while(tmp != NULL){

if(strcmp(tmp->deviceName,name) == 0){

return tmp;

}

tmp = tmp->next;

}

return NULL;

}

}

void* fire_pthread(void *data) //火灾报警线程处理函数

{

struct Devices *fire;

struct Devices *beep;

int status;

fire = findDeviceByName(pdeviceHead,"fire"); //从设备链表找出火灾检测和蜂鸣器

beep = findDeviceByName(pdeviceHead,"beep");

fire->deviceInit(fire->pinNum);

beep->deviceInit(beep->pinNum);

while(1){ //检测到火灾通过蜂鸣器报警

status = fire->readStatus(fire->pinNum);

if(status == 0){

beep->open(beep->pinNum);

printf("fire warning\n");

delay(20000);

}else

beep->close(beep->pinNum);

}

int main()

{

pthread_t fire_pth;

if(wiringPiSetup()<0){//初始化wiringPi外设库

printf("wiringPi Init failed\n");

return -1;

}

//1.指令工厂初始化

//2.设备控制工厂初始化

pdeviceHead = addFireToDeviceLink(pdeviceHead); //将火灾检测加入设备链表

pdeviceHead = addBeepToDeviceLink(pdeviceHead); //将蜂鸣器加入设备链表

//3.线程池建立

//3.3火灾线程

ret = pthread_create(&fire_pth,NULL,fire_pthread,NULL);

if (ret != 0) {

printf("Failed to create firethread.\n");

return -1;

}

//等待线程退出

pthread_join(fire_pth,NULL);

return 0;

}
