Description

Technical Field

[0001] The present invention relates to the technical field of in-vehicle environment early warning, and in particular to an in-vehicle environment early warning system and method based on ultra-low power consumption Bluetooth. Background Art

[0002] With the transformation and upgrading of the domestic automobile market, automobile companies urgently need to improve the health level in the car to meet consumers' demand for healthy car use and ensure the physical and mental health of drivers and passengers. Therefore, the requirements for in-car environmental warnings are becoming increasingly higher. At the same time, the maturity of Bluetooth technology provides a solid foundation for the stable and continuous operation of in-car environmental warnings.

[0003] Existing in-vehicle environment warning systems are often unable to conduct real-time analysis of the vehicle's operating conditions and are difficult to adjust the system's monitoring objects. On the one hand, the system consumes a lot of power, and ordinary warning systems are difficult to apply to vehicles for a long time. Frequent charging of the system will also bring a bad experience to users; on the other hand, existing systems often regulate temperature and cannot take into account other factors that affect users' driving of the vehicle; on the other hand, even if other factors that affect users' driving of the vehicle are taken into account, there is a lack of alarm devices that issue different alarms for different data abnormalities, and it is difficult for users to adjust the driving environment according to the alarms.

[0004] Therefore, people need an in-vehicle environment warning system and method based on ultra-low power Bluetooth to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an in-vehicle environment warning system and method based on ultra-low power Bluetooth to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an in-vehicle environment warning system based on ultra-low power Bluetooth, the system comprising: an in-vehicle data acquisition module, a monitoring mode switching module, an in-vehicle environment warning module and an in-vehicle data display module; Collecting in-vehicle environment data through the in-vehicle data collection module; Analyze the driving state of the vehicle through the monitoring mode switching module, and switch the system to a driving monitoring mode and an ultra-low power consumption monitoring mode; The in-vehicle environment warning module analyzes the in-vehicle environment data, and when any in-vehicle environment data reaches a threshold, an abnormal alarm of any in-vehicle environment data is triggered; when the in-vehicle environment coefficient reaches a threshold, a poor in-vehicle environment alarm is triggered; The in-vehicle data display module displays the in-vehicle environment data, and when the in-vehicle environment early warning module triggers an alarm, the triggered alarm content is displayed.

[0007] Furthermore, the in-vehicle data acquisition module includes an air pressure sensor, a temperature sensor, a humidity sensor and an alcohol content sensor. The air pressure in the vehicle is collected and recorded in real time by the air pressure sensor, the temperature in the vehicle is collected and recorded in real time by the temperature sensor, the humidity in the vehicle is collected and recorded in real time by the humidity sensor, and the alcohol content in the air in the vehicle is collected and recorded in real time by the alcohol content sensor. The in-vehicle environmental data includes the in-vehicle air pressure, the in-vehicle temperature, the in-vehicle humidity and the in-vehicle air alcohol content. The frequency of collecting the in-vehicle environmental data is set by the system.

[0008] Furthermore, the monitoring mode switching module monitors the user's vehicle speed in real time through a speed sensor, thereby analyzing the vehicle's driving state as a running state or a stopped state. When the vehicle's driving state is a running state, the system adopts a driving monitoring mode; when the vehicle's driving state is a stopped state, the system adopts an ultra-low power consumption monitoring mode. In the driving monitoring mode, the system turns on the air pressure sensor, temperature sensor, humidity sensor and alcohol content sensor to simultaneously monitor the data inside the vehicle. In the ultra-low power consumption monitoring mode, the system turns on the alcohol content sensor to monitor the data inside the vehicle.

[0009] Furthermore, the in-vehicle environment warning module is connected to the in-vehicle data acquisition module via Bluetooth. When the system adopts the driving monitoring mode, it simultaneously determines whether the in-vehicle air pressure, in-vehicle temperature, in-vehicle humidity and in-vehicle air alcohol content exceed the threshold value. When any in-vehicle environment data exceeds any in-vehicle environment data threshold value, any in-vehicle environment data abnormal alarm is triggered. The in-vehicle air pressure, in-vehicle temperature, in-vehicle humidity and in-vehicle air alcohol content are comprehensively considered, and the in-vehicle environment coefficient is analyzed. When the in-vehicle environment coefficient is lower than the minimum threshold value of the in-vehicle environment coefficient, a poor in-vehicle environment alarm is triggered. When the system adopts the ultra-low power consumption monitoring mode, the in-vehicle environment warning module determines whether the in-vehicle air alcohol content exceeds the maximum threshold value of the in-vehicle air alcohol content. When the in-vehicle air alcohol content reaches the maximum threshold value of the in-vehicle air alcohol content, an abnormal in-vehicle air alcohol content alarm is triggered.

[0010] Furthermore, the in-vehicle data display module includes a display screen. When the in-vehicle environment warning module triggers any in-vehicle environment data abnormal alarm, the display screen displays any in-vehicle environment data abnormal alarm, and marks the alarm environment data with different colors. When the in-vehicle environment warning module triggers the in-vehicle air alcohol content abnormal alarm, the display screen reminds the user not to drive after drinking.

[0011] A vehicle interior environment early warning method based on ultra-low power Bluetooth comprises the following steps: S1: When the user's vehicle starts, the system switches the monitoring mode to the driving monitoring mode. When the user's vehicle stops, the system starts to record the vehicle's stop time. When the vehicle's stop time reaches the stop state judgment time, the system switches the monitoring mode to the ultra-low power consumption monitoring mode. S2: Collect in-vehicle environment data in driving monitoring mode or ultra-low power consumption monitoring mode; S3: Analyze the in-vehicle environment data. When any in-vehicle environment data reaches a threshold, an abnormal alarm for any in-vehicle environment data is triggered. When the in-vehicle environment coefficient reaches a threshold, a poor in-vehicle environment alarm is triggered. S4: The system displays the in-vehicle environment data. When the in-vehicle environment data abnormal alarm is triggered, the triggered alarm content is displayed. When the in-vehicle air alcohol content abnormal alarm is triggered, the user is required to manually issue instructions to the system.

[0012] Furthermore, in step S1, the system monitors the user's vehicle speed V in real time through a speed sensor. When V>0, the system determines that the user's vehicle is in a running state and switches the monitoring mode to a driving monitoring mode. When V=0, the system starts to record the vehicle's stop time T until T≥T0, at which time the system switches the monitoring mode to an ultra-low power consumption monitoring mode, where T0 is the system's established stop state judgment time. The system uses a speed sensor to monitor the vehicle's running state. The speed sensor has high real-time performance and can be used to monitor the running state and dynamic characteristics. It has high reliability, a simple structure and a long service life.

[0013] Furthermore, in step S2, when the system switches the monitoring mode to the driving monitoring mode, the system collects and records the air pressure A in the vehicle in real time through the air pressure sensor. i , collect and record the temperature B in the car in real time through the temperature sensor i , collect and record the humidity C in the car in real time through the humidity sensor i , the alcohol content sensor collects and records the air alcohol content D in the driving monitoring mode in real time i ; When the system switches the monitoring mode to the ultra-low power monitoring mode, the system collects and records the air alcohol content in the ultra-low power monitoring mode in real time through the alcohol content sensor D q , i is the i-th monitoring of the system in the driving monitoring mode, q is the q-th monitoring of the system in the ultra-low power monitoring mode, and the alcohol gas in the gas can be monitored. The more concentrated the alcohol gas in the gas, the greater the signal that the alcohol content sensor can detect, and the higher the alcohol content in the blood, the higher the alcohol content in the exhaled gas. According to international standards, the alcohol content in exhaled breath is 2100 times that in blood, so we can judge whether the alcohol content in the blood has reached the level of drunk driving based on the monitored alcohol content in the exhaled breath.

[0014] Further, in step S3, when the monitoring mode is the driving monitoring mode, when the air pressure A in the vehicle i ≥a1 or vehicle interior pressure A i When the temperature in the car is less than a2, the system triggers the abnormal air pressure alarm; when the temperature in the car is B i≥b1 or vehicle interior temperature B i When the humidity in the car is less than b2, the system triggers an abnormal temperature alarm; when the humidity in the car is C i ≥c1 or humidity in the car C i When the alcohol content in the air is less than C2, the system triggers an abnormal humidity alarm in the car; when the alcohol content in the air is D i ≥D, the system triggers an abnormal alarm for the alcohol content in the air in the car, where a1 is the highest threshold of the air pressure in the car set by the system, a2 is the lowest threshold of the air pressure in the car set by the system, b1 is the highest threshold of the temperature in the car set by the system, b2 is the lowest threshold of the temperature in the car set by the system, c1 is the highest threshold of the humidity in the car set by the system, and c2 is the lowest threshold of the humidity in the car set by the system. i 、Indoor temperature B i 、In-car humidity C i and the alcohol content of the air in the car i , calculate the in-vehicle environment coefficient W when monitoring the in-vehicle environment for the i-th time i : ; Where K A is the weight of the influence of the air pressure inside the car on the interior environment coefficient, K B is the weight of the influence of the interior temperature on the interior environment coefficient, K C is the weight of the influence of the humidity inside the car on the interior environment coefficient, K D is the weight of the influence of the alcohol content in the car air on the car environment coefficient, A is the human body comfortable air pressure set by the system, B is the human body comfortable temperature set by the system, C is the human body comfortable humidity set by the system, and D is the threshold value for judging drunk driving by the alcohol mass concentration in the breath. When the car environment coefficient W i When the vehicle interior environment coefficient W is less than i ≥W, the system determines that the in-vehicle environment is poor and triggers the poor in-vehicle environment alarm, where W is the in-vehicle environment coefficient threshold that triggers the poor in-vehicle environment alarm. The in-vehicle environment coefficient threshold W is calculated as: ; Among them, k is the in-car environment tolerance set by the system. When the monitoring mode is ultra-low power monitoring mode, the system analyzes the alcohol content D in the air in the car. q , when the alcohol content in the car air is D q When ≥D, the system triggers an alarm for abnormal alcohol content in the air in the vehicle.

[0015] In step S4, when the system triggers the alarm of abnormal alcohol content in the air in the vehicle, the system issues a warning to the user not to drive after drinking, until the user sends an instruction to the system that the driver is not drinking. The system triggers the alarm, further enhancing the safety awareness of the vehicle driver and ensuring the safety of the people driving and riding in the vehicle.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: the system connects sensors via ultra-low energy Bluetooth, which can reduce power loss. On the one hand, the system uses a speed sensor to monitor the vehicle's operating status, and reduces the monitored objects when the vehicle stops, thereby reducing the system's power consumption and improving the user experience. On the other hand, the system comprehensively considers the pressure, temperature and humidity, and alcohol content in the vehicle, taking into account multiple factors that affect the user's driving and riding of the vehicle, thereby enhancing the comprehensiveness of the system. On the other hand, the system issues different alarms for different data anomalies, which concretely shows the differences in the in-vehicle environmental warnings, laying the foundation for users to adjust the driving environment according to the alarms.

When the in-vehicle environment warning module triggers an abnormal alarm for the alcohol content in the air in the vehicle, the display screen reminds the user not to drive after drinking.
