Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1 and Figure 2 which shows an in-vehicle living body detection system based on a millimeter-wave radar provided by an embodiment of the present invention, including a linear drive module 100, a monitoring device 200, and a remote terminal 300. The linear drive module 100 includes a slide rail 110 provided on the top of the vehicle interior, a monitoring platform 120 slidably connected to the slide rail 110, and a drive motor 130 for driving the monitoring platform 120 to slide reciprocally along the slide rail 110. There are two slide rails 110, which extend from the front end to the rear end of the vehicle interior. The drive motor 130 is connected to a drive screw 150 through a coupling 140. The extending direction of the drive screw 150 is parallel to the central axis of the vehicle roof. The drive screw 150 is screwed with a drive nut 160, and the drive nut 160 is fixedly connected to the monitoring platform 120. The monitoring device is installed on the monitoring platform 120, so that the drive motor 130 can drive the monitoring platform 120 to slide. The remote terminal 300 is remotely connected to the monitoring device 200 through a network module 240, so as to remotely control and operate the monitoring device 200; the monitoring device 200 includes a main control module 210, and a power supply module 220, a monitoring module 230, a network module 240, a voice module 250, and a positioning module 260 respectively connected to the main control module 210; the main control module 210 is connected to the drive motor 130; the power supply module 220 includes a built-in battery 221; the monitoring module 230 includes a millimeter-wave radar detection module 231, an oxygen concentration monitoring module 232, an infrared detection module 235, and a temperature detection module 233. The millimeter-wave radar detection module 231 is used to monitor whether there is a living body in the vehicle, the temperature detection module 233 is used to monitor the temperature in the vehicle, and the oxygen concentration monitoring module 232 is used to monitor the oxygen content concentration in the vehicle; the network module 240 is used to receive and send data; the voice module 250 includes a microphone 251 and a speaker 252; the positioning module 260 is used to obtain the current positioning information of the vehicle; the remote terminal 300 includes a handheld mobile terminal 310, and the monitoring module 230 further includes a camera module 234; the camera module 234 is used to take photos or videos of the detected living body and send the photo or video to the remote terminal 300 for staff to view.

[0019] Further, the power supply module 220 is connected to the vehicle power supply. The power supply module 220 is used to supply power to other functional modules inside the monitoring device 200 and also to monitor whether the vehicle has stalled. When the vehicle is not stalled, the vehicle power supply supplies power to each functional module inside the monitoring device 200 and charges the built-in battery 221; when the vehicle stalls, the vehicle power supply is cut off, and then the built-in battery 221 supplies power to each functional module inside the monitoring device 200; by obtaining whether it is the vehicle power supply or the built-in battery 221 that supplies power to each functional module inside the monitoring device 200, the starting or stalling state of the vehicle can be obtained. When the vehicle stalls and the temperature inside the vehicle is higher than or lower than the preset value, or the oxygen content concentration inside the vehicle is lower than the preset value, the monitoring device enters the monitoring state.

[0020] Further, the remote terminal 300 includes a handheld mobile terminal 310, and the monitoring device 200 is connected to the handheld mobile terminal 310 through a 4G or 5G network.

[0021] Further, the pick-up 251 is also used to monitor the sound inside the vehicle. When the monitoring device enters the monitoring state, the pick-up 251 is also used to monitor whether there is any abnormal sound inside the vehicle. If there is, the monitoring device 200 sends a reminder message through the network to the handheld mobile terminal 310; the speaker 252 is used to play the voice message sent from the remote terminal 300 to the monitoring device 200.

[0022] Further, the monitoring device 200 further includes a door control module, and the door control module is used to control the opening and closing of the door lock. The staff can remotely operate to open the door lock through the remote terminal 300, so that the trapped person can get out of the car in time and avoid the safety risk caused by the inability of the staff to arrive at the scene in time.

[0023] Further, an alarm module 270 is also included. The alarm module 270 is connected to the main control module 210, and the alarm module includes an external vehicle speaker 271. When the monitoring device 200 detects that someone is trapped in the car, and the remote terminal 300 does not respond within the preset time, the alarm module continuously emits a preset voice help message through the external vehicle speaker, such as "Please help, there may be someone trapped in the vehicle", and dials the alarm phone through the network module 240 and sends the vehicle positioning information and vehicle information to the alarm platform.

[0024] Working principle: When the power supply module 220 detects that it is connected to the vehicle power supply, the power supply module 220 disconnects the power supply from the main control module 210 and charges the built-in battery 221. At this time, the monitoring device 200 is in a silent state; when the power supply module 220 detects that it is disconnected from the vehicle power supply, and the monitoring device 200 detects that the temperature inside the vehicle is higher or lower than the preset value, or the oxygen content concentration inside the vehicle is lower than the preset value, then the monitoring device 200 enters the monitoring state. When the monitoring device 200 enters the monitoring state, the main control module 210 drives the monitoring platform 120 to slide along the slide rail 110, thereby driving the monitoring device 200 to slide. At the same time, the millimeter-wave radar detection module 231 scans different areas inside the vehicle; when the millimeter-wave radar detection module 231 detects a living body at a certain position, it takes pictures and records through the camera module 234. Then, the monitoring device 200 sends a reminder message, as well as the picture or video recording, to the handheld mobile terminal 310 through the network and waits for the handheld mobile terminal 310 to respond; if the staff confirms through the handheld mobile terminal 310 that the monitoring device 200 has made a misjudgment, the monitoring device 200 continues to monitor other positions inside the vehicle; if the staff confirms that someone is left in the vehicle, the in-vehicle personnel can be awakened through the speaker 252. The in-vehicle personnel can also have a voice call with the staff through the microphone 251 and can open the door through the door control module to let the trapped personnel get out of the vehicle; if the staff does not respond to the reminder message within the preset time, the alarm module continuously sends a preset voice help message to passers-by through the external vehicle speaker, such as "Please help, there may be someone trapped in the vehicle", and dials the alarm phone through the network module 240 and sends the vehicle positioning information and vehicle information to the alarm platform. Connect and communicate with the remote terminal 300 through the network module 240, so as to avoid misjudgment and missed judgment of the situation inside the vehicle by the monitoring device 200, and improve the speed and accuracy of handling emergencies.
