The first time period may be set to 1-5 minutes. The reminder information may be used to be sent to the driver of the vehicle or to set up relevant emergency contacts.

When the server side continuously identifies that a human body exists in the vehicle, the temperature of the space in the vehicle continuously exceeds a preset value in any time period, the time period exceeds a second time period, the second time period is longer than the first time period, and the server side generates alarm information used for sending the alarm information to the outside. The second time period is set to 8-15 minutes.

The alarm information is sent to a police system and a fire fighting system through a server. The police system and the fire system can give an alarm after confirmation.

Example two

On the basis of the first embodiment, the monitoring end comprises: and the positioning module is used for second positioning information and is connected with the communication module, the communication module sends the second positioning information to the server, and the alarm information contains the second positioning information.
