Description

Technical Field

[0001] The invention relates to the technical field of oxygen regulation in a car cockpit, and in particular to an oxygen regulation system in a car cockpit. Background Art

[0002] As cars become more and more popular in people's lives, the development of automobile technology is closely linked to people's life needs. On-board oxygen generators are a type of machine that produces oxygen on board. People usually use on-board oxygen generators to release oxygen to increase the oxygen content in the cockpit. Increasing the oxygen content in the cockpit is beneficial to the driver's health, especially for long-distance drivers. It can effectively help them dispel sleepiness, keep a fresh mind when driving the vehicle, and avoid traffic accidents.

[0003] Announcement No. CN112706580A discloses an oxygen regulation system for a car cockpit, including an oxygen concentration sensor in the car, an electronic air pressure gauge, a blood oxygen detector, an on-board computer, a CAN line controller, an electronic display module, a human-computer interaction module, and an oxygen production execution module. The present invention detects the oxygen concentration in the cockpit in real time through an oxygen concentration sensor and an electronic air pressure gauge, and calculates the oxygen partial pressure value in the cockpit. The oxygen partial pressure value directly affects the blood oxygen saturation in the driver and the passengers in the car. The oxygen partial pressure value detection data in the car is compared by the CAN line controller and the on-board computer, and the comparison result is output on the electronic display module in the car, which helps the driver in the car to judge whether he is currently in an oxygen-deficient or fatigued driving state. At the same time, the system will send a warning signal and remind the driver to perform oxygen supplementation. An oxygen regulation system for a car cockpit of the present invention provides a solution for the interaction between the personnel in the cockpit and the car computer, which is conducive to maintaining the physical and mental health of the driver and passengers and ensuring safe driving.

[0004] The above patent improves on the shortcomings of the existing in-vehicle air purification systems in the prior art, which only detect PM2.5 or other harmful particles or gases such as carbon monoxide and activate the air purification function, but are unable to detect the oxygen content in the car. The oxygen partial pressure in the car is calculated to directly reflect the blood oxygen saturation of the driver or passenger, and then judge the driving status. The present application provides another implementation plan for the problems raised in the above patent. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an automobile cockpit oxygen adjustment system, which has the advantages of being able to accurately adjust the oxygen in the automobile cockpit according to the external environment and purify the internal environment of the vehicle, and solves the problem that the existing in-vehicle air purification systems in the prior art only detect other harmful particles or gases such as PM2.5 or carbon monoxide and start the air purification function, but cannot detect the oxygen content in the vehicle. It directly reflects the blood oxygen saturation of the driver or passenger by calculating the oxygen partial pressure in the vehicle, and then judges the driving status.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automobile cockpit oxygen adjustment system, comprising an oxygen adjustment system, the oxygen adjustment system comprising an on-board driving computer, an external environment monitor, a CAN controller, an electronic barometer, a plateau mode, a city mode, a blood oxygen detector, and an in-car air purification, the output ends of the external environment monitor, the electronic barometer and the blood oxygen detector are electrically connected to the input end of the CAN controller, the output end of the CAN controller is electrically connected to the input end of the on-board driving computer, the output end of the on-board driving computer is electrically connected to the input ends of the plateau mode, the city mode, and the in-car air purification, the plateau mode includes in-car standby oxygen generation and storage and personalized oxygen supply, the output end of the plateau mode is electrically connected to the input end of the in-car standby oxygen generation and storage and the personalized oxygen supply, the city mode includes an external circulation oxygen supply and a regenerative HEPA filter, and the city mode is electrically connected to the input ends of the external circulation oxygen supply and the regenerative HEPA filter.

It analyzes the data collected by the sensor through a built-in algorithm, calculates the air quality index (AQI) or other indicators, and combines artificial intelligence technology to predict the trend of air quality changes. It supports communication with the vehicle system, mobile phone app or cloud platform, making it convenient for users to view data, and is linked with the vehicle air-conditioning system to achieve automatic control.

[0008] Further, the functions of the CAN controller include: The data frame processing module is responsible for generating and parsing CAN data frames, including standard frames (11-bit identifiers) and extended frames (29-bit identifiers), and supports different types of frames, such as data frames, remote frames, error frames, and overload frames; The arbitration mechanism module implements the arbitration function of the CAN bus to ensure that when multiple nodes send data at the same time, frames with high priority can be sent first; Error detection and processing module, providing multiple error detection mechanisms, such as bit error, fill error, CRC error, format error, etc., supporting error active mode and error passive mode to ensure the reliability of communication; A data buffer module provides a sending buffer and a receiving buffer for storing data frames to be sent and received; The interrupt management module supports the interrupt mechanism and sends an interrupt signal to the main processor when a data frame is received or an error occurs; The filtering and shielding module provides hardware filtering functions, allowing users to set the received frame identifier range, filter out unnecessary frames, and reduce the burden on the main processor; The baud rate configuration module supports flexible baud rate settings to meet different communication rate requirements.

[0011] Furthermore, the in-car air purification is formed by combining a negative ion generator, photocatalyst technology and ultraviolet disinfection technology. Negative ions can combine with positive ions in the air to form aggregates, thereby reducing suspended particles and bacteria in the air and improving air freshness. Photocatalysts can decompose organic matter and harmful gases under light, and have a bactericidal and disinfecting effect, which helps to purify the air in the car. Ultraviolet (UV) lamps can kill bacteria and viruses in the air and play a role in disinfection and purification. It is particularly suitable for the peak influenza season and epidemic period.

[0012] Furthermore, the in-vehicle standby oxygen generation and storage consists of an electrochemical oxygen generator and a high-pressure oxygen cylinder.

[0022] Harmful gas detection monitors harmful gases in the air outside the car (such as formaldehyde, volatile organic compounds (VOC), etc.) to remind drivers to pay attention to air pollution.

[0023] Automatically switch between internal and external circulation. According to the air quality outside the car, the vehicle's air conditioning system is automatically controlled to switch between internal and external circulation to prevent pollutants outside the car from entering the car.

[0024] Data visualization presents the monitored air quality data to the driver through the vehicle screen, mobile phone app or other display devices.

[0025] Linked with the air purification system, when the air quality outside the car is poor, the air purification system in the car (such as HEPA filter, negative ion generator, etc.) is started to improve the air quality in the car.

[0026] Historical data recording and analysis: Record historical data of air quality outside the vehicle to help users understand long-term air pollution trends.

[0030] The baud rate configuration module supports flexible baud rate settings to meet different communication rate requirements (typically ranging from 10 kbps to 1 Mbps).

[0031] The electronic barometer is a digital electronic barometer. Through digital signal processing technology, the air pressure changes detected by the sensor are converted into digital signals, which is convenient for integration with other digital devices (such as microcontrollers, display screens, etc.). It can detect tiny air pressure changes, provide accurate data, monitor air pressure changes in real time, and adapt to dynamic environmental needs.

[0032] The blood oxygen monitor is a wrist-worn blood oxygen monitor with a design similar to that of a smart watch, integrated into a wristband, and is suitable for exercise and continuous monitoring.

[0033] The in-car air purification is a combination of negative ion generator, photocatalyst technology and ultraviolet disinfection technology. Negative ions can combine with positive ions in the air to form aggregates, thereby reducing suspended particles and bacteria in the air and improving the freshness of the air. Photocatalysts can decompose organic matter and harmful gases under light, and have a bactericidal and disinfecting effect, which helps to purify the air in the car.

[0034] The in-vehicle backup oxygen generation and storage consists of an electrochemical oxygen generator and a high-pressure oxygen cylinder. The electrochemical oxygen generator generates oxygen by electrolyzing water or other electrochemical methods. The high-pressure oxygen cylinder can store the oxygen generated by the electrochemical oxygen generator for backup. Personalized oxygen supply integrates micro oxygen nozzles in the seats or headrests to provide oxygen directly to the driver or passengers.

[0035] The working principle of the above embodiment is: The vehicle's external environment can be monitored in real time through the external environment monitor. When the vehicle's external environment is harsh, the vehicle's internal air and the air entering the vehicle are purified and filtered through the CAN controller and the on-board driving computer using vehicle purification and city modes to ensure the cleanliness of the vehicle's internal environment. When the vehicle is driving in plateau areas, the plateau mode is turned on with the cooperation of the electronic barometer and the GPS of the on-board driving computer, and the driver's blood oxygen index is monitored in real time using the blood oxygen meter. When the blood oxygen meter detects that the driver's blood oxygen index drops rapidly, the backup oxygen in the vehicle will be activated to generate and store oxygen with a higher concentration into the vehicle's cockpit. At the same time, personalized oxygen supply is used to release oxygen to the driver's mouth and nose, which helps prevent the driver from experiencing altitude sickness.
