[0002] With the rapid development of the automotive industry, the importance of in-vehicle safety and monitoring systems is becoming increasingly prominent. However, current in-vehicle monitoring technologies mainly rely on simple weight sensors or cameras, which have many shortcomings. Weight sensors struggle to accurately detect lightweight objects such as children or pets, while cameras experience a significant performance drop in low-light conditions. Furthermore, these traditional methods cannot monitor the vital signs and subtle movements of occupants in real time, making it difficult to detect potential safety risks promptly. In addition, the reliability of traditional monitoring systems decreases significantly in extreme temperatures or prolonged enclosed environments, and most systems only offer alarm or adjustment functions, failing to provide adequate monitoring of in-vehicle life and users. Therefore, developing a new in-vehicle monitoring technology that overcomes these shortcomings is urgently needed.

[0036] This utility model proposes an environmental monitoring device, which includes an alarm component 5 and an execution component 3. The alarm component 5 is used to issue a prompt to personnel, and the execution component 3 is used to adjust the in-vehicle environment. The monitoring device includes:
[0037] Infrared sensor 2 is used to collect infrared sensing signals inside the vehicle;
[0038] The in-vehicle environment monitoring circuit 4 is used to monitor the in-vehicle environment and output an environment monitoring signal;
[0039] The main control circuit 1 is electrically connected to the in-vehicle environment monitoring circuit 4 and the infrared sensor 2. The main control circuit 1 is also electrically connected to the alarm component 5 and the execution component 3. The main control circuit 1 is equipped with a low-risk alarm mode and an abnormal response mode, which are used to control the in-vehicle environment monitoring circuit 4 to start when a human body is detected based on the collected infrared sensing signal.
[0040] The main control circuit 1 is also used to control the alarm component 5 to work in the low-risk alarm mode according to the received environmental monitoring signal, or to control the alarm component 5 and the execution component 3 to work in the abnormal response mode according to the received environmental monitoring signal.
[0041] In this embodiment, to improve the accuracy of monitoring the in-vehicle environment, the infrared sensor 2 employs a high-sensitivity passive infrared sensor (D220 human infrared sensor, sensing distance: 3-7 meters; sensing angle: 120°; covering multiple seat areas in the vehicle), combined with a Fast Fourier Transform (FFT) algorithm, to achieve real-time monitoring of vital signs (such as breathing and subtle movements) inside the vehicle. Signal analysis distinguishes human characteristics from environmental interference, ensuring accurate and reliable detection. Furthermore, even when no human is detected in the vehicle, only the infrared sensor 2 can be activated for monitoring, thereby reducing the device's power consumption. The in-vehicle environment monitoring circuit 4 can be implemented using a CO2 sensor, temperature and humidity sensor, VOC sensor, etc., to monitor in-vehicle air quality, temperature, humidity, and other environmental parameters in real time, ensuring the comprehensiveness and accuracy of the data. After receiving these environmental monitoring signals, the main control circuit 1 performs intelligent analysis. Once it detects that the in-vehicle environmental indicators exceed a preset first safety threshold, it will immediately trigger the corresponding alarm component 5, such as an audible and visual alarm, to attract the attention of personnel. Meanwhile, based on the specific environmental monitoring signals, when the in-vehicle environmental indicators exceed the preset second safety threshold, the main control circuit 1 will control the execution component 3 to trigger an abnormal response mode to take corresponding measures to adjust the in-vehicle environment and implement alarm functions, such as automatically turning on the air purification device, controlling the temperature control unit 33 (e.g., air conditioner) to adjust the in-vehicle temperature, and controlling the window drive control unit 32 to adjust the windows, etc., to quickly improve the in-vehicle environment and ensure the health and safety of passengers. The main control circuit 1 can use STM32 (suitable for efficient data processing) or ESP32 (integrated Wi-Fi and BLE modules). The alarm component 5 can be implemented by a buzzer, headlights, in-vehicle display screen and audio system, etc., or when the main control circuit 1 uses ESP32, it can be implemented by wirelessly connecting to an external terminal, such as a mobile phone, computer and smart speaker. The execution component 3 can control corresponding electrical equipment, such as air purification device, air conditioner, window motor, etc., through a relay module or CAN communication bus.
[0042] The number of first and second safety thresholds depends on the number of sensors used and can be configured by developers according to actual application needs. For example, when using carbon dioxide (CO2) sensors, temperature and humidity sensors, and volatile organic compound (VOC) sensors, the first and second safety thresholds will each be set to three different values. Developers can also precisely set each value according to the actual application scenario. For example, for a temperature sensor, the first safety threshold can be set to 40°C and the second safety threshold to 45°C to prevent infants from being placed in a high-temperature environment when the user is not in the vehicle. When the ambient temperature reaches the first safety threshold, the system will alert the user through a low-risk alarm mode; if it reaches the second safety threshold, the system will activate an abnormal response mode, adjust the vehicle's interior temperature, and issue an alarm to avoid potential hazards from high temperatures. Similarly, the first safety threshold for a temperature sensor can also be set to 15°C and the second safety threshold to 10°C to prevent infants from being placed in a low-temperature environment when the user is not in the vehicle. When the ambient temperature drops to the first safety threshold, the system will alert the user through a low-risk alarm mode; if it drops to the second safety threshold, the system will activate an abnormal response mode, adjust the interior temperature and issue an alarm to avoid potential hazards caused by low temperatures.
[0043] Specifically, the infrared sensor 2 collects infrared signals from inside the vehicle and outputs them to the main control circuit 1. Based on the collected infrared signals, the main control circuit 1 controls the in-vehicle environment monitoring circuit 4 to start when it detects heat radiation emitted by the human body. The in-vehicle environment monitoring circuit 4 monitors the in-vehicle environment and outputs environmental monitoring signals to the main control circuit 1. When the received environmental monitoring signals exceed a preset first safety threshold, the main control circuit 1 controls the alarm component 5 to operate in the low-risk alarm mode. The functions in the low-risk alarm mode and the abnormal response mode can be fixed by the R&D personnel or set by the vehicle owner through an external terminal.
[0044] Furthermore, the in-vehicle environment monitoring circuit 4 also includes
[0045] Temperature monitoring sensor 41, which is electrically connected to the main control circuit 1, is used to monitor the temperature inside the vehicle and output a temperature monitoring signal to the main control circuit 1;
[0046] Air monitoring sensor 42 is used to monitor the air inside the vehicle and output an air monitoring signal to the main control circuit 1.
[0047] In this embodiment, the temperature monitoring sensor 41 is specifically a DHT22 temperature and humidity sensor used to monitor the temperature and humidity inside the vehicle, and the air monitoring sensor 42 is specifically an MH-Z19B CO2 sensor used to monitor carbon dioxide concentration to assess air quality.
[0048] Furthermore, the execution component 3 also includes:
[0049] A timing circuit 31 is electrically connected to the main control circuit 1. When the main control circuit 1 is working in the abnormal response mode, it starts timing according to a preset time and outputs a drive control signal after timing is completed.
[0050] A window drive control unit 32 is electrically connected to the main control circuit 1 and is used to adjust the vehicle windows.
[0051] Temperature control unit 33, which is electrically connected to the main control circuit 1, is used to regulate the temperature inside the vehicle.
[0052] The main control circuit 1 is also used to drive the window drive control unit 32 and / or the temperature control unit 33 to work when the drive control signal is received.
[0053] In this embodiment, the main control circuit 1 is connected to the window drive control unit 32 and the temperature control unit 33 via a CAN bus. The timing circuit 31 can be implemented by a 555 timer circuit 31 or a crystal oscillator in the main control chip. The window drive control unit 32 can be driven by a CAN controller such as P8xC591 to adjust the height of the window. The temperature control unit 33 can be controlled by a microcontroller (such as P8xC592) to operate the in-vehicle air conditioner and adjust the in-vehicle temperature.
[0054] Referring to the above embodiments, in a parking scenario, after initialization, the main control circuit 1 uses infrared sensor 2 and environmental sensor to collect in-vehicle data in real time. First, the main control circuit 1 checks the collected infrared signals for signs of life. If no signs of life are found, infrared sensor 2 collects data again at intervals. If the main control circuit 1 determines that signs of life are present based on the collected infrared signals, it activates temperature monitoring sensor 41 and air monitoring sensor 42, outputting temperature and air monitoring signals to the main control circuit 1. If the main control circuit 1 detects that the ambient temperature has risen to the first safety threshold (40°C) based on the temperature monitoring signal, and there is no human body in the front driver's seat according to the distance algorithm, the main control circuit 1 (ESP32), equipped with a wireless communication module, then... The temperature monitoring signal is sent to an external terminal, such as an APP, to push a low-risk alarm message to the user's mobile phone to alert the user. If the main control circuit 1 detects that the ambient temperature has risen to the second safety threshold (45°C) based on the temperature monitoring signal, the timing circuit 31 starts timing according to the preset time and pushes a high-risk alarm message to the user's mobile phone through the APP to alert the user. If the user responds in time, ventilation or cooling operations can be performed remotely through the APP. If the user does not respond in time within the preset time, the timing circuit 31 outputs a drive control signal to the main control circuit 1 to control the main control circuit 1 to drive the window drive control unit 32 and / or the temperature control unit 33 to work according to the abnormal response mode set by the user, thereby adjusting the temperature inside the vehicle. This can prevent tragedies caused by children being accidentally left in the vehicle in a high-temperature environment.
[0055] It is worth mentioning that if the main control circuit 1 detects that the ambient temperature has dropped to the first safety threshold (15°C) based on the temperature monitoring signal in the above scenario, it will issue a remote alarm and push a low-risk alarm message to the user's mobile phone to alert the user. If the main control circuit 1 detects that the ambient temperature has dropped to the second safety threshold (10°C) based on the temperature monitoring signal, it will directly perform ventilation or heating operations remotely through the APP. If the user does not respond in time within the preset time, the timing circuit 31 will output a drive control signal to the main control circuit 1 to control the main control circuit 1 to drive the window drive control unit 32 and / or the temperature control unit 33 to work according to the abnormal response mode set by the user, so as to adjust the temperature inside the car and prevent children from being accidentally left in the car in a low-temperature environment, which could lead to tragedy.
[0056] In another long-distance driving scenario, during extended driving, both the driver and passengers often overlook changes in the in-vehicle environment. This can lead to excessively high carbon dioxide concentrations, causing drowsiness and potentially resulting in traffic accidents. Therefore, if the main control circuit 1 detects that the CO2 concentration has risen to the first safety threshold (e.g., 2000 ppm) based on air monitoring signals, and if a human body is detected in the front passenger compartment using a distance algorithm, the main control circuit 1 (ESP32), equipped with a wireless communication module, sends a temperature monitoring signal to an external terminal. This allows the external terminal, such as an app, to push a low-risk alert to the user's mobile phone to warn them. If the main control circuit 1 detects that the CO2 concentration has risen to the first safety threshold (e.g., 2000 ppm) based on air monitoring signals, and if the main control circuit 1 detects that the CO2 concentration has risen to the first safety threshold (e.g., 2000 ppm), ... When the signal detects that the CO2 concentration inside the vehicle has risen to the second safety threshold (e.g., 2500 ppm), the timing circuit 31 starts timing according to a preset time and pushes a high-risk alarm message to the user's mobile phone via the APP to alert the user. If the user responds in time and turns on the air purifier for ventilation or adjusts the window height via the electronic display, the timing circuit 31 stops working. If the user does not respond in time within the preset time, the timing circuit 31 outputs a drive control signal to the main control circuit 1 after the timing is completed, so as to control the main control circuit 1 to drive the window drive control unit 32 to work according to the abnormal response mode set by the user, thereby adjusting the air environment inside the vehicle. This can prevent the air quality inside the vehicle from deteriorating and causing driver fatigue.
[0057] In one embodiment, the environmental monitoring device further includes:
[0058] The wireless communication module 7 is electrically connected to the main control circuit 1 and is used to communicate with an external terminal.
[0059] In this embodiment, if the main control circuit 1 is not equipped with a wireless communication module, the wireless communication module 7 is electrically connected to the main control circuit 1 and is used to transmit the environmental monitoring signals (such as CO2 concentration, temperature, etc.) monitored by the main control circuit 1 to an external terminal, such as a user's smartphone or vehicle information system. Thus, even if the main control circuit 1 itself does not have wireless communication capabilities, it can still communicate with external devices through the external wireless communication module 7, ensuring that the user can obtain real-time monitoring data of the in-vehicle environment and that the user can control the execution component 3 via an APP to adjust the in-vehicle environment.
[0060] Furthermore, the wireless communication module 7 is one or more of the following: Bluetooth communication module, WIFI communication module, infrared communication module, and ZigBee communication module.
[0061] In one embodiment, the environmental monitoring device further includes:
[0062] The positioning sensor 6 is electrically connected to the main control circuit 1 and is used to output a positioning signal to the external terminal through the wireless communication module when the main control circuit 1 is working in the abnormal response mode.
[0063] In this embodiment, the positioning sensor 6 can be a GPS module (NEO-6M), which acquires the current geographical location information of the vehicle through GPS satellite signals. When the main control circuit 1 detects an abnormal environmental monitoring signal (e.g., excessively high CO2 concentration or excessively high temperature) and triggers an abnormal response mode, the positioning sensor 6 can be activated to work in conjunction with the main control circuit 1. At this time, the main control circuit 1 sends an alarm signal containing the positioning signal to the user's smartphone or in-vehicle information system through a wireless communication module. In this way, the user can not only be aware of abnormal conditions in the vehicle's interior environment in real time, but also quickly obtain the vehicle's specific location, facilitating timely action to ensure driving safety. In addition, this function can also provide valuable positioning signals to the user in case of vehicle theft or emergency, enhancing the vehicle's safety performance.
[0064] In one embodiment, the alarm component 5 includes:
[0065] The first alarm unit 51, the first alarm component 5 is electrically connected to the main control circuit 1, and is used to alert the people in the vehicle when the main control circuit 1 is working in the low-risk alarm mode or the abnormal response mode.
[0066] The second alarm unit 52, the second alarm component 5 is electrically connected to the main control circuit 1, and is used to alert people outside the vehicle when the main control circuit 1 is working in the abnormal response mode.
[0067] In this embodiment, the first alarm unit 51 can be implemented through in-vehicle devices such as a vehicle control screen, buzzer, and audio system, while the second alarm unit 52 can be implemented through devices such as headlights and horn. When the main control circuit 1 detects an environmental monitoring signal that triggers the first safety threshold, a low-risk alarm mode is triggered. At this time, the first alarm unit 51 can be activated to display relevant information on the vehicle control screen, or a soft alarm sound can be emitted through devices such as a buzzer and audio system to attract the attention of the occupants, but without causing excessive panic. The occupants can open windows for ventilation or adjust the in-vehicle environment as needed based on the alarm prompts to ensure a comfortable ride. When the main control circuit 1 detects an environmental monitoring signal that triggers the second safety threshold, an abnormal response mode is triggered, and the first alarm unit 51 and the second alarm unit 52 can be activated simultaneously. The first alarm unit 51 continues to issue alarms to the occupants, reminding them to take immediate action, such as stopping the vehicle and leaving the vehicle. At the same time, the second alarm unit 52 will be activated, using flashing headlights and honking horns to send emergency signals to people outside the vehicle, attracting the attention of surrounding pedestrians and vehicles and buying more rescue time and attention for the people inside the vehicle. This dual-alarm mechanism is designed to maximize the safety of the people inside the vehicle and improve the speed and effectiveness of response in emergency situations.
[0068] This utility model also proposes an environmental monitoring system, which includes an environmental monitoring device A and an external terminal B. The specific structure of the environmental monitoring device A is as described in the above embodiments. Since this environmental monitoring system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The external terminal B is communicatively connected to the main control circuit 1 (ESP32). The external terminal B can be composed of smart terminal devices such as mobile phones, computer equipment, or tablet computers. Through wireless communication methods, such as Bluetooth, Wi-Fi, or mobile data networks, the external terminal B can receive data and information from the environmental monitoring device A in real time. Users only need to install the corresponding application on their mobile phones or computers to remotely monitor the environmental conditions inside the vehicle, such as key indicators like air quality, temperature, and humidity. Once abnormal data is detected, the external terminal B will immediately push an alarm notification, enabling users to respond quickly and take measures to ensure passenger safety and comfort. In addition, the external terminal B also provides historical data query and analysis functions to help users better understand the changing trends of the in-vehicle environment and provide a reference for subsequent travel decisions.
[0069] This utility model also proposes an automobile, which includes windows, body and an environmental monitoring system as described above.
[0070] In an embodiment of this utility model, an environmental monitoring device is employed. The environmental monitoring device includes an alarm component 5 and an execution component 3. The alarm component 5 is used to alert personnel, and the execution component 3 is used to adjust the in-vehicle environment. The monitoring device includes: an infrared sensor 2 for collecting infrared signals from inside the vehicle; an in-vehicle environment monitoring circuit 4 for monitoring the in-vehicle environment and outputting environmental monitoring signals; and a main control circuit 1 electrically connected to the in-vehicle environment monitoring circuit 4 and the infrared sensor 2, as well as the alarm component 5 and the execution component 3. The main control circuit 1 is equipped with a low-risk alarm mode and an abnormal response mode. Based on the collected infrared signals, it controls the in-vehicle environment monitoring circuit 4 to activate when a human body is detected. The main control circuit 1 is also used to control the alarm component 5 to operate in the low-risk alarm mode, or to control the alarm component 5 and the execution component 3 to operate in the abnormal response mode, based on the received environmental monitoring signals. Thus, the infrared sensor 2 collects infrared sensing signals from the human body inside the vehicle and sends them to the main control circuit 1. When the main control circuit 1 identifies a human body based on the infrared sensing signal, it controls the in-vehicle environment monitoring circuit 4 to start monitoring the in-vehicle environment and outputs an environment monitoring signal. When the main control circuit 1 receives the environment monitoring signal, it controls the alarm component 5 to work in the low-risk alarm mode, or controls the alarm component 5 and the execution component 3 to work in the abnormal response mode. This enables the infrared sensor 2 to analyze and distinguish human characteristics from environmental interference, ensuring accurate and reliable detection. When an abnormality is detected based on the environment monitoring signal, it performs alarm function processing or alarm function and adjustment function processing.
