智能家居 (5) ——智能家居项目整合（语音控制线程，网络控制线程、烟雾报警线程）

 

目录

一、主函数

mianPro.c

二、指令工厂

voiceControl.c

socketControl.c

inputCommand.h

三、设备工厂

smokeAlarm.c

buzzer.c

livingroomLight.c

restaurantLight.c

bedroomLight.c

bathroomLight.c

controlDevice.h

四、总结

问题1：三线程同时运行，有时候无法正常进行开关灯操作。

问题2：在前几篇文章中，在open\close操作前都有Init操作

问题3： int (*changeStatus)(int status)，记住设备的状态

四、总结

问题1：三线程同时运行，有时候无法正常进行开关灯操作。

初步排查：烟雾线程占用CPU100%，怀疑是死循环。

解决办法：加入延时函数。

问题2：在前几篇文章中，在open\close操作前都有Init操作

解决办法：通过指令进行初始化

if(strcmp("CSHALL",CmdHandler->command) == 0){
        tmp = findDeviceByName("smokeAlarm",pdeviceHead);
		if(tmp != NULL)  tmp->Init(tmp->pinNum);
		tmp = findDeviceByName("buzzer",pdeviceHead);
		if(tmp != NULL)  tmp->Init(tmp->pinNum);
		tmp = findDeviceByName("livingroomLight",pdeviceHead);
		if(tmp != NULL)  tmp->Init(tmp->pinNum); 
		tmp = findDeviceByName("restaurantLight",pdeviceHead);
		if(tmp != NULL)  tmp->Init(tmp->pinNum);
		tmp = findDeviceByName("bedroomLight",pdeviceHead);
		if(tmp != NULL)  tmp->Init(tmp->pinNum);
		tmp = findDeviceByName("bathroomLight",pdeviceHead);
		if(tmp != NULL)  tmp->Init(tmp->pinNum);
        printf("设备已全部初始化\n");
	}

问题3： int (*changeStatus)(int status)，记住设备的状态

记住设备的状态，已经执行的open、close、Init就不再执行，同时解决问题2。
