Specifically, referring to fig. 3, it can be understood that when the vehicle body 100 is stationary for a long time after flameout, the main control module 300 will start the temperature sensing module 220 and the gas sensing module 230 to monitor the temperature and the oxygen content in the vehicle, and when the temperature in the vehicle is too high, i.e. exceeds the temperature threshold, and when the oxygen content in the vehicle is too low, i.e. is lower than the oxygen concentration threshold, it indicates that the undesirable living body in the vehicle is in the environment for a long time. Therefore, the main control module 300 controls the on-off of the infrared sensing module 210 to detect whether a vital sign exists in the vehicle, and if the vital sign is detected, immediately sends a dangerous alarm to the external terminal through the communication module 260 to prompt a person at a far end to immediately take rescue actions. In some embodiments, the temperature sensing module 220 may employ a temperature sensor; the gas sensing module 230 may employ an oxygen sensor and a carbon dioxide sensor; the infrared sensing module 210 may employ an infrared sensor; the communication module 260 may employ GSM or GPRS; the main control module 300 may be a single chip microcomputer, a DSP or an ARM.
Further, since the infrared sensing module 210 is mainly used for sensing the displacement of the object at about 37 ℃, if the ambient temperature is close to 37 ℃, erroneous judgment is easy to occur; at the same time, the monitored object cannot be detected if the monitored object does not move, such as an infant placed in a bedding. Therefore, by further using the image acquisition module 250 to acquire the in-vehicle image, it can be determined whether a living body exists in the vehicle to make up for the drawbacks of the infrared sensing module 210. It will be appreciated that the image capturing module 250 may employ conventional photographic or video equipment without ir function, and if an ir camera is employed, it is too costly to be widely used in practice.
