【NUCLEO-U575ZI-Q测评】+ESP8266远程切断家庭用电
本帖最后由 416775364TP 于 2023-3-18 12:50 编辑以前的装修的时候智能家居还没有兴起或者未成熟、价格虚高，所以家里面的供电、照明系统还有其它家用电器都不支持远程开关，出门后老是觉得灯没关，或者空调、风扇没关，网上也有报道说有人出去打工一年回来空调未关，电费大几十万。此次想法是给家里的电箱内部加一个远程开关，目前只支持单方通信，后续加入开关状态上报，切换设备故障上报，市电电压、电流、频率等上报，实时了解家里用电器负载状态。电路设计如下：图1：市电取电图2电流检测图3输出检测&继电器驱动如上原理图系统取电来自市电降压产生，继电器控制原理图，一共接了两个继电器，一个继电器（RY2）接在常闭端，一个接在常开端(RY1)， 避免由于某些原因出现继电器(RY1)粘死，输出不能有效断开情况，则动作常闭端继电器(RY2),切断输出。输出电压检测集成频率和过零检测，实现继电器零点动作，避免拉弧及大电流情况发生，电流检测方便判断家里用电器负荷状况。市电取电及继电器、采样板为制作完成，采用板上集成的3个LED作为指示调试用，PA5 绿灯表示RY2,亮表示处在常闭端，PB7蓝灯表示RY1状态，吸合时亮起，红灯告警，报继电器拉弧粘死不能断开或者损坏不能正常吸合。
外接ESP12-F WIFI模块作为远程通信，WIFI模块与demo板串口2连接，取5V电作为工作电源。阿里云提供免费物联网公共测试平台，数据量小，完全可以使用此免费的作为自身控制云平台，DEMO版使用AT指令控制WIFI模块，需要烧录MQTT协议固件连接阿里云（见附件），手机APP也连接阿里云，阿里云平台上面设置产品流转，实现二者通信，其中如何连接阿里云，网络有教程参考，其中需要注意的几个点需要说明下。1.配置MQTT客户端IDAT+MQTTCLIENTID=0,"i7lwMWR4n.ESP8266|securemode=2\,signmethod=hmacsha256\,timestamp=16768075338|"如上，前面需要手动加上\,另外timestamp的值刷新后会变，另外见下图passwd也会变，需要注意，所以连不上WIFI时需要修改参数重新连接.APP借用网上有的先做测试，如下图：后续借用APP Inventor进行开啊，减少语言障碍。WIFI模块返回云平台通信数据如下：测试开启正常输出时：检测到继电器处于输出状态，而未正常输出以及继电器切断输出，而继续输出红灯告警，切开常闭继电器Rly2和常开继电器Rly1/* USER CODE END Header *//* Includes ------------------------------------------------------------------*/#include "main.h"

这个并不难
不难，就是花点钱罢了~ 想法非常好，但是吧，最好考虑NB- IOT来实现，ESP8266耗电了，不能实现电池供电。也就不能全部切断电源了。 阿里云那个平台可以挂多少设备？ 这要实现远程开关机电脑，是不是还要加一些别的东西？ 这个项目自己做来玩一玩还是不错的选择！ 这个继电器能承受多大电流啊 使用的是AT指令吗？ 如何用esp8266作为随身wifi esp8266能和手机wifi连接吗 ESP8266怎么连接以及控制外部设备? 可以连接阿里云实现的吗？ APP可以使用点灯科技的APP来开发 esp8266可以做路由器吗? esp826612e和esp826612f 有啥区别 esp8266串口wifi 无线模块怎么组网
