设计要求

本设计研究的是关于基于STM32的家庭防火防盗的系统，该系统以STM32单片机作为采集和控制核心，利用了多种传感器进行信息的采集，如使用温湿度传感器获取环境温湿度来为家庭提供区域环境信息数字化，使用可燃气体传感器来为系统提供可燃气泄漏、烟雾等用于实时监控房屋内部发生火灾的可能性，做到实时报警，采用语音录放模块进行智能化语音提示，使用OLED屏幕进行信息可视化如温湿度、烟雾浓度、室内人员状态、报警状态的显示功能，使用继电器作为家庭电源开关，总到报警自动关闭的功能，使用风扇进行抽风，放出出现可燃气体浓度过高大致家庭起火的安全隐患，使用嵌入式硬件实现机器视觉进行人脸检测的功能，防止陌生人闯入。使用GSM模块与家庭主人进行实时通信，以便家庭主人能够实时获取到家庭内部的安全信息状态。本系统的设计功能和参数如下所示。
2.1.1 设计功能
（1）实时检测室内可燃气体和烟雾浓度，做到实时监测和触发预警（阈值可自定义设置）。
（2）实时采集室内温湿度，湿度并在OLED屏上显示。
（3）系统触发烟雾预警后会自动打开窗口开启风扇进行抽风，同时切断室内电器电源。
（4）系统可以设置人脸识别（通过宽动态人脸识别摄像头模组，实现活体检测，人脸检测功能），可设定识别数量不少于10位。当识别三次都未成功时判定为未知人员闯入，触发系统预警。
（5）系统触发报警后能够通过短信通知用户预警内容。
2.2.2 设计参数
（1）温度：0℃ ～ +50℃ （可设阈值）,精度：±2℃；湿度：20-90%RH，精度：±5%RH
（2）烟雾浓度：10-5000PPM ，精度：±20ppm
（3）设备自检周期：180天
（4）脸部轮廓参数：68或128个特征点
（5）识别成功率：98%以上，识别速度：1S以内
2.2 系统整体框架
本设计以STM32单片机作为系统控制核心，完成对外来人员的人脸检测，采用LCD液晶屏对采集到的人脸数据进行可视化显示，采用OLED屏对采集到的温湿度、烟雾浓度，以及可能需要的人脸信息验证等，尽量做到系统信息显示直观，方便用户能够简洁获取到当前系统运行状态和需要了解的数据信息。故本系统由温湿度检测模块，烟雾传感器MQ2，人脸识别模块K210，独立按键采集模块进行数据的采集，由STM32单片机对采集的数据进行处理，使用LCD和OLED将数据进行分块显示，利用LED和蜂鸣器进行声光报警，使用SIM模块利用短信将报警信息发送到用户手机。本系统的整体框架如图2.1所示。

实物

本系统调试硬件方面主要做的工作为人脸识别模块调试、传感器数据的采集、显示以及报警状态。人脸识别模块相对来说比较复杂，因为该模块数据协议多，故而要具体了解模块的整个工作的通信流程，传感器数据的采集与显示与报警则是本系统的核心，能够正常的采集数据并且在屏幕上可视化显示出来是最主要的实物调试并根据预设进行声光报警。

人脸识别模块的调试

人脸识别模块根据数据手册和本系统对模块的使用需求分为人脸采集（录入）、人脸识别、人脸删除三大功能，根据第四章软件调试内容将这三大过程制作如图5.2所示的流程。

图5.2 人脸识别模块调试

相对应的人脸识别模块的三个实物调试结果如图5.3所示，可以看到模块和单片机能够正常通讯并按照第四章所介绍的人脸识别流程正常工作，模块各个状态的均可在实物中正常工作，在识别成功时OLED屏幕能够正常显示主人，识别到非录入人员是显示非法入侵者，在设定界面能够进行人脸的录入和删除。

传感器采集与显示

如下图所示为本系统的实物图调试时的大致框架，从中可以看到实物需要显示多个界面，用于信息采集、显示、阈值设定等。可以看出预设计界面和通过实物调试出的界面大致相当，中间根据需求做了些许显示改动，但大体一致的。

模块设计

温湿度模块

本系统采用的是DHT11温湿度传感器，通过此温湿度传感器采集家庭环境中的温湿度的数值，因不同的环境温湿度具体数据是不一样的，比如家庭内部和家庭外部的温湿度就有很大不同，故而采用温湿度能够为家庭用户带来更加精准的数字化环境情况参考。

烟雾浓度MQ2

本系统为了检测家庭内部的烟雾、可燃物浓度而使用了MQ2传感器，通过该传感器输出模拟量送入单片机的模拟输入IO口，通过单片机内部内置的12位高精度模数转换器将输入电压转换为数字量，通过非线性运算获得对应的浓度值。MQ2烟雾浓度传感器是金属氧化物二氧化锡为主的N型半导体而制成的气敏性半导体元器件，该金属氧化物半导体元器件具有较低的电导率，能够检测空气冲存在的烟雾等气敏性气体。模块的浓度探测范围光，灵敏度高，驱动电路相对简单，且模块稳定性非常高，对于检测气体响应非常灵敏快速。本系统单片机的IO口最能容忍3.6V的模拟电压输入，但是无法满足烟雾传感器模块的直接输入，因该模块的模拟输出量最高是5V故而如果使用MQ2传感器输出直接连单片机引脚会造成芯片承受不可逆的损害，故而本次为了满足设计要求需要对MQ2的输出做分压处理，将模拟输出电压5V能够降到单片机可容忍的范围，本次采用了简单的电阻分压设计，即采用两个电阻阻值为3：2的电阻串接到输出引脚作为分压处理单元，经过分压后输入到单片机模拟输入引脚PA1的电压最大为3V，用此方法就能满足模拟设计输入需求。

GSM模块

本次使用的是GSMA6-B模块，该模块体积小巧，相比传统的SIM800A等GSM模块来说体积缩小了一倍有余，且该模块供电要求有所降低，传统的SIM800A无线通信模块一般要求电源电压为6V2A以上，而该模块仅需要5V1A即可完成正常的电源供电需求。该模块支持发送SMS短信、语音通话、GPRS传输等基本的通信功能，模块标准的AT指令，默认使用的是115200bps的波特率与单片机进行通信，采用串口方式连接到单片机的串口3即PB10和PB11引脚。使用GSMA6模块需要注意的是模块串口电平是3.3V的不能和5V单片机串口直接连接，通过USB串口模块进行调试时也需要用支持3.3V串口电平的USB调试模块才行，否则模块通信可能会出现问题。

人脸识别模块

本系统采用了基于K210模块的DEMO板用于人脸识别，K210是一个集成RISC-V双核64位CPU的模块，该模块拥有最高1TOPS算力且功耗仅为0.3W，该模块内置了AI人脸识别算法和模型库，使用串口进行人脸识别信息的输出，模块支持波特率可调最低为9600bps最高可达115200bps，模块的时钟频率为600MHZ，继承了一个8MB的闪存SRAM，该模块支持DVP输出，最高输出为60帧。K210模块内置的AI人脸识别算法经过了大量的训练和验证，识别结果成熟可靠，官方说明该AI人脸识别模型的识别率已经大于99.9%，且支持活体检测，因此能够有效防止使用图片蒙混检测系统的问题。K210模块内置了500-8000个人脸特征库，使用了彩色的双目镜头用于人脸采集，使用了两个红外补光灯能够在夜间依然保持有效、高准确、高反应的检测结果。K210模块与本系统主控单片机的串口1即PA9和PA10接口相连接进行信息的通信传输。由于K210的DEMO板设计不合理，导致DEMO板载引脚接口无法使用，本次通过飞线将K210模块的串口引脚和GND引脚引出。

语音报警模块

本系统使用的语音播放模块为JQ8400F，该模块支持MP3、WAV格式的音频硬解码，支持FAT文件系统因此可以像U盘一样直接通过USB口连接电脑进行音频文件的管理如导入导出。模块支持多种控制模式如单线串口模式和异步串口通信模式以及并行IO控制模式，模块支持音量大小调节，将音量分为1-30的等级进行音量调整。
