本申请实施例提供一种汽车内部生物体检测报警***，如图1所示，该***包括：云平台30、传感器模块10以及通讯模块20，传感器模块10用于根据预设频率检测汽车内部的温度以及是否有生物体存在，生成检测信号，并将检测信号通过通讯模块20上传至云平台30，云平台30根据检测信号生成报警信号。在一具体实施方式中，该汽车内部生物体检测报警***主要是在汽车停放在某一位置，且汽车内部为一个封闭的环境即车门关闭的情况下工作。
本申请实施例提供的汽车内部生物体检测报警***，通过设置传感器模块，可以对汽车内部的温度以及是否有生物体存在进行检测，同时设置云平台可以在收到检测信号时生成报警信号。因此，本申请实施例提供的汽车内部生物体检测报警***，可以降低或避免由于大人或家长的疏忽，儿童或者宠物被关在汽车中，长时间由于密闭空间的温度过高而丧生事件的发生。同时，本申请实施例提供的汽车内部生物体检测报警***中，传感器模块按照预设频率进行检测，即传感器模块每隔预设时间工作一次，由此可以大大降低整个***的工作功耗。
在一实施例中，如图2所示，传感器模块10包括：呼吸侦测传感器11和温度传感器12，呼吸侦测传感器11用于检测汽车内部是否有生物体存在，当检测到生物体存在时，生成第一检测信号；温度传感器12用于检测汽车内部的温度，并根据检测的温度生成第二检测信号。
在一具体实施方式中，该呼吸侦测传感器11为现有的传感器，可以直接购买使用。该呼吸侦测传感器11中内置多普勒雷达传感器和MCU，例如可以将多普勒雷达传感器和MCU集成到芯片中形成呼吸侦测传感器11。该 呼吸侦测传感器11通过多普勒频移效应，侦测物体的运动信号，具体可以将人呼吸时胸腔起伏的微弱运动信号提取出来，并放大后单独一路输入到MCU进行分析和计算。MCU能够对人体呼吸时胸腔起伏时产生的微弱运行信号进行处理，并结合IIR(Infinite Impulse Response，递归滤波器)数字滤波算法以及呼吸信号修正算法，准确分析判断房间内是否有人存在。在一实施例中，当呼吸侦测传感器11检测到汽车内部有人或其他生物体存在时，可以生成第一检测信号。
在一实施例中，如图3所示，为了使得传感器模块可以按照预设频率进行检测，可以在汽车内部生物体检测报警***中设置休眠电路40，休眠电路40连接传感器模块10和通讯模块20，休眠电路40每隔预设时间启动传感器模块10和通讯模块20。在一具体实施方式中，可以在休眠电路40中设置定时器，通过定时器中设置的时间每隔预设时间启动传感器模块10和通讯模块20，例如可以设置每隔一分钟启动一次，也可以设置为其他时间，但设置的预设时间不宜过长，避免被锁在汽车中的人或宠物等发生危险。
在一实施例中，休眠电路40每隔预设时间启动温度传感器12，当第二检测信号超过第一预设阈值时，启动呼吸侦测传感器11，当接收到第一检测信号时，启动通讯模块20。在一具体实施方式中，可以在休眠电路40中设置比较电路，比较电路连接温度传感器12，当温度传感器12采集到汽车内部的温度值后传输至比较电路中，同时休眠电路40中设置有第一预设阈值，例如为35度或30度等，比较电路接收到温度传感器12传输的温度值后，将其和第一预设阈值比较，若大于预设阈值，则输出第一高电平信号， 休眠电路40可以根据该第一高电平信号启动呼吸侦测传感器11工作，当呼吸侦测传感器11检测到生物体存在，输出第一检测信号至休眠电路40，休眠电路40接收到第一电测信号可以生成第二高电平信号，并根据该第二高电平信号启动通讯模块20工作。此时，通讯模块20可以将呼吸侦测传感器11检测的第一检测信号和温度传感器12检测第二检测信号传输至云平台30。

在一实施例中，云平台30包括：比较模块，比较模块用于接收第二检测信号，判断第二检测信号是否超过第一预设阈值，当第二检测信号超过第一预设阈值且接收到第一检测信号时，生成报警信号。在一实施例中，若在休眠电路40中设置了比较电路，当云平台30接收到第一检测信号和第二检测信号时，则说明休眠电路40已判定汽车内部的温度超过第一预设 阈值且检到了汽车内部存在生物体，此时，云平台30可以直接生成报警信号。因此，若在休眠电路40中设置了比较电路，则云平台30中可以不设置比较模块。
在一实施例中，如图4所示，汽车内部生物体检测报警***还包括：报警终端50，报警终端50连接云平台30，报警终端50接收云平台30输出的报警信号。在一具体实施方式中，报警终端50可以是手机端，例如可以在手机端中设置APP，也可以直接将报警信号发送至手机的微信公众号中。
在一实施例中，由于呼吸侦测传感器11、温度传感器12和2G物联网卡均是低功耗设备，每次工作时间短，功耗小，可以利用充电电池工作。由此可以在汽车内部生物体检测报警***中设置充电电池，充电电池连接温度传感器12和呼吸侦测传感器11，用于为温度传感器12和呼吸侦测传感器12充电。其中，当通讯模块20为2G物联网卡时，充电电池也可以连接2G物联网卡，为2G物联网卡供电。
在一具体实施方式中，为了能够及时对充电电池充电，避免传感器模块和通讯模块因电量低而无法工作，该汽车内部生物体检测报警***还包括：电量检测模块，电量检测模块连接充电电池，用于监测充电电池的电量，当电量低于第二预设阈值时，生成电量提示信号。具体地，该电量检测模块可以是电池电量检测芯片，电量检测模块可以连接通讯模块20，当生成电量提示信号时，可以通过通讯模块20发送至报警终端50，提示用户及时充电。
在一实施例中，本申请实施例提供的汽车内部生物体检测报警***可以按照以下流程工作：休眠电路40启动温度传感器12工作，并接收温度 传感器12采集的温度值，通过内置的比较电路判断该温度值是否超过第一预设阈值，当超过第一预设阈值时，启动呼吸侦测传感器11工作，若接收到呼吸侦测传感器11输出的第一检测信号，启动通讯模块20工作，通讯模块20将接收的呼吸侦测传感器11输出的第一检测信号和温度传感器12输出的第二检测信号(即采集的温度值)传输至云平台30，云平台30生成报警信号传输至报警终端50，提示用户。同时用户在报警终端50查询到电量检测模块输出的电量提示信号时，可以对充电电池进行充电，保持呼吸侦测传感器11、温度传感器12、以及2G物联网卡的正常工作。
虽然关于示例实施例及其优点已经详细说明，但是本领域技术人员可以在不脱离本申请的精神和所附权利要求限定的保护范围的情况下对这些实施例进行各种变化、替换和修改，这样的修改和变型均落入由所附权利要求所限定的范围之内。对于其他例子，本领域的普通技术人员应当容易理解在保持本申请保护范围内的同时，工艺步骤的次序可以变化。
此外，本申请的应用范围不局限于说明书中描述的特定实施例的工艺、机构、制造、物质组成、手段、方法及步骤。从本申请的公开内容，作为本领域的普通技术人员将容易地理解，对于目前已存在或者以后即将开发出的工艺、机构、制造、物质组成、手段、方法或步骤，其中它们执行与本申请描述的对应实施例大体相同的功能或者获得大体相同的结果，依照本申请可以对它们进行应用。因此，本申请所附权利要求旨在将这些工艺、机构、制造、物质组成、手段、方法或步骤包含在其保护范围内。
