The invention discloses an automatic alarm device for staying people in a vehicle, which is characterized in that a human body sensor is arranged in the vehicle, a pressure sensor is arranged below a driver seat, and a controller, a sound alarm and an optical signal alarm are additionally arranged. The human body sensor transmits sensed human body signals to the controller, and the controller comprehensively judges whether a person is in the vehicle or not, whether a driver sits in a driving position or not and whether a vehicle door is closed or not according to signals transmitted by the driver position pressure sensor and an original vehicle door sensor of the vehicle. When a person is in the vehicle, the vehicle door is closed, and the driver leaves the driving position, the controller judges that the driver carelessly leaves the person in the vehicle and is ready to leave. At the moment, the controller enables the sound alarm and the optical signal alarm to send out alarm signals through a signal line to remind the driver to check whether people stay in the vehicle or not, and therefore danger is avoided.
本发明公开了一种车内滞留人员自动报警装置,在车内安装人体感应器,司机座位下安装压力传感器,另有一个控制器,一个声音报警器和光信号报警器。人体感应器把感应到的人体信号传输到控制器,控制器再通过司机位压力传感器和车辆原有的车门感应器传送过来的信号,综合判断车内是否有人员,以及司机是否坐在驾驶位,车门是否关上。当车内有人员,并且车门已关闭,而且司机已离开驾驶位时,所述控制器判断司机不慎把人员遗留在车内且正准备离开。此时控制器通过信号线,使声音报警器和光信号报警器发出报警信号,提醒司机检查车内是否还有人员滞留,从而避免发生危险。
