The invention provides an alarm system for children detained in a vehicle. The alarm system comprises a main control unit module, a TFT color screen module, a pyroelectric module, a motor module, an openmv machine vision module, a temperature and humidity sensor, an air quality sensor, a GPS module, a GSM module, a buzzer module and a highlight diode module. Whether a dynamic target exists in the vehicle or not can be monitored in real time while power consumption is low, and it is guaranteed that the system can work for a long time without affecting vehicle starting; pyroelectricity and an openmv machine vision module are matched to determine whether a child is left in the vehicle or not, and the false alarm rate is reduced; when it is determined that the child stays in the car and the temperature exceeds an early warning value, the car window can automatically descend by a certain height, the temperature in the car is reduced, and air circulation is improved; a danger alarm lamp and a display screen are turned on to remind passers-by, and a mobile phone alarm short message is sent to a vehicle owner and 110 in time; and the death rate of children left in the car is greatly reduced.

    本申请提供了一种儿童滞留车内报警系统,包括主控单元模块、TFT彩屏模块、热释电模块、电机模块、openmv机器视觉模块、温湿度传感器、空气质量传感器、GPS模块、GSM模块、蜂鸣器模块、高亮二极管模块。本申请可以在低电量消耗的同时能够实时监测车内是否有动态目标,保证系统能够长期工作且不影响车辆启动;采用热释电以及openmv机器视觉模块相配合以此确定车内是否存在滞留儿童,降低误报率;确定车内儿童滞留且温度超过预警值时,能够自动下降一定高度的车窗,降低车内温度、提高空气流通;开启危险报警灯和显示屏提醒过路人,并及时向车主和110发送手机报警短信;大大降低了儿童因被滞留在车内的死亡率。
