The working principle of the vehicle-mounted life monitoring and alarm system of the present invention is as follows:

The first step is to install the system in the car, firstly insert the SIM card obtained from the service provider into the SIM card socket (2) on the host, and then use the magic glue (19) on the host cover (18) to insert the The host of the system is installed at the rear of the interior roof of the car, adjust the angle of the ball joint head (7), so that the visible range of the infrared night vision camera (8) can cover as much space as possible in the car, and then lead out from the host The power supply and signal bus (11) of the vehicle are connected with the central control system of the vehicle, and the installation of the system is completed since then.

In the second step, press the power switch (5) to start the system, the system enters the standby state, start the car to charge the battery (14) inside the host through the power supply and signal bus (11), and the working indicator light (6) will display Red until the battery (14) is fully charged, the working indicator light (6) changes to green. The system is connected to terminals such as mobile phones or tablet computers through the wireless network control circuit (27), and multiple terminal devices notified when the system alarms are set.

The third step is to turn off the engine, pull out the key, and lock the car through the central control. The system will be activated after receiving the locking signal from the central control of the car through the power supply and signal bus (11), and enter the working state. At this time, the ultrasonic distance measuring probe (3), the microphone (4), the infrared night vision camera (8), the temperature sensing probe (9) and the GPS positioning circuit (30) respectively start to collect corresponding data, and pass the storage circuit (21) Save, through the wireless network control circuit (27), the data can be viewed from a distance at any time by using a terminal such as a mobile phone or a tablet computer. If all the data monitored by the system are normal, the system will remain in this state until the car is started again, and then the system will enter the standby state again.

In the fourth step, if the data monitored by the system is abnormal, for example, the distance data collected by the ultrasonic distance measuring probe (3) changes, which means that there are moving objects in the car; or the microphone (4) collects human voice signals or loud noises. At this time, the system will enter the judgment state. The system will remotely provide video, audio and GPS positioning signals to multiple terminal devices set before through the wireless network control circuit (27), and ask whether to enter the alarm state. (28) Turn on the car air conditioner and alarm system, and if you get a response from the terminal equipment, choose whether to enter the alarm state according to the feedback signal. At the same time, the system will always monitor the temperature inside the car through the temperature sensing probe (9) after entering the judgment state. When the temperature inside the car is higher than 45 degrees, the system will enter the alarm state even if no confirmation signal is The control circuit (28) turns on the automobile air conditioner and the alarm system, so as to avoid delays and delays caused by terminal failure or human factors.

The fifth step, after the system enters the alarm state, the system will ask the terminal device whether to enable voice or video calls. After enabling, the user can communicate with the trapped baby through the microphone (4), infrared night vision camera (8) and speaker (16). Toddlers make voice or video calls to observe the state of trapped infants and young children, soothe their emotions, and teach them to save themselves.

Step 6: After the user unlocks the central control of the car and starts the car, the system receives a signal from the central control through the power supply and signal bus (11), stops the alarm, and switches back to the standby state again.

The advantages of the present invention are: composite life activity detection through ultrasound, audio and infrared video, which ensures the reliability of the detection results; the system can be linked with the central control of the car to control the car's air conditioner and alarm system, even if the car owner finds it too late to rush back , The system can also automatically adjust the environment in the car and give an alarm, which greatly improves the survival rate of forgotten infants and young children. In addition, this system can also interact with mobile phones through the wireless network, and at the same time provide alarms to multiple mobile phone users and provide GPS positioning information of vehicles. The user who reported to the police found the vehicle as soon as possible and started rescue.
