Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle safety management, and particularly relates to a vehicle safety management terminal based on a gyroscope sensor. BACKGROUND

[0002] Traditional vehicle safety management methods mostly adopt a unified standard mode, that is, a unified safety standard and operation parameter are used for different types of vehicles. However, different types of vehicles, such as cars, trucks, and buses, have significant differences in design structure, performance characteristics, and purposes. For example, trucks usually have larger body sizes and higher load capacities, and their braking distances and steering flexibility are quite different from those of cars; buses pay more attention to passenger comfort and safety, and have special requirements for body stability and emergency evacuation design. The unified safety standard cannot fully consider these differences, resulting in overly lenient safety management for some vehicles and overly strict safety management for others, making it difficult to achieve precise safety control and increasing the safety risk of vehicle operation.

[0003] Secondly, the load state of a vehicle has an important influence on its running performance and safety condition. With the increase of load, the braking performance of the vehicle will decrease, and the friction between the tire and the ground will also change, thereby affecting the controllability and stability of the vehicle. Traditional vehicle safety management methods often ignore this key factor and are difficult to dynamically adjust the safety operation parameters according to the actual load of the vehicle.

[0004] Therefore, it is necessary to provide a vehicle safety management terminal based on a gyroscope sensor to solve the above technical problems. SUMMARY

BRIEF DESCRIPTION OF DRAWINGS

[0014] Figure 1 The application is a module structure diagram of a vehicle safety management terminal based on a gyroscope sensor. DETAILED DESCRIPTION

[0015] The application will be further described below in combination with the drawings and embodiments.

[0016] Embodiment one As shown in the drawings, a vehicle safety management terminal based on a gyroscope sensor specifically comprises: Figure 1 In the specific implementation process, the specific steps of the identification and extraction module are: The vehicle type is identified by reading the vehicle model information automatically through the vehicle identification code or through the vehicle-mounted communication module, the vehicle type safety database pre-constructed and stored locally or in the cloud is accessed based on the identified vehicle type, the standard safety operation parameters of each type of vehicle in the normal working condition in the vehicle type safety database, the standard safety operation parameters corresponding to the current vehicle type are extracted from the database, including the angle change, the angular velocity and the acceleration.

[0017] ​Specifically, the vehicle identification code is obtained from the vehicle registration information, which contains detailed information of the vehicle, such as the manufacturer, production year, vehicle model, etc., from which the type of the vehicle can be determined. After identifying the type of the vehicle, the storage location of the vehicle type safety database is determined according to the pre-configured information. If the database is stored locally, the specific folder or database file on the local storage device is directly accessed; if the database is stored in the cloud, an access request is sent to the cloud server through a network connection such as Wi-Fi, 4G / 5G mobile network, etc. After accessing the database, the identified vehicle type is used as the query key to perform an accurate query in the vehicle type safety database. The vehicle type safety database retrieves the standard safety operation parameter records corresponding to the vehicle type according to the query condition and extracts the standard safety operation parameters. It should be noted that the vehicle type safety database is a database constructed according to the standard safety operation parameters of existing vehicles of various types.

[0018] In the specific implementation process, the specific steps of the parameter definition module are as follows: According to the extracted standard safety operation parameters corresponding to the current vehicle type, the deviation threshold section is divided; according to the three different load states of the vehicle, i.e. empty load, half load and full load, the weights of angle change, angular velocity and acceleration are set respectively. Specifically, in the full load state, the parameters with high weight are set to include acceleration and angle change; in the empty load state, the parameter with high weight is set to include angular velocity; in the half load state, the weights of angle change, angular velocity and acceleration are equal.

[0019] Specifically, after obtaining the standard safety operation parameters corresponding to the current vehicle type, including angle change, angular velocity and acceleration, etc., these parameters are first sorted to determine the standard value range of each parameter. In this embodiment, the deviation threshold section is divided into normal section, slight deviation section, moderate deviation section and severe deviation section. For example, for the angle change parameter, if its standard range is -5° to 5°, the normal section is -2° to 2°, the slight deviation section is -3° to -2° and 2° to 3°, the moderate deviation section is -4° to -3° and 3° to 4°, and the severe deviation section is less than -4° or greater than 4°. The angular velocity and acceleration are also specifically divided in the same way.

[0020] In this embodiment, in the full load state, the acceleration weight is set to 0.4 and the angle change weight is set to 0.4, so the angular velocity weight is 0.2; in the empty load state, the angular velocity weight is set to 0.5, the angle change weight is set to 0.3, and the acceleration weight is set to 0.2; in the half load state, since the three parameters have relatively balanced influence, the weights of angle change, angular velocity and acceleration are all set to 1 / 3. It should be noted that the sum of the weights of all parameters is 1.

[0021] In the implementation process, the specific steps of the correlation analysis module are: Obtain the vehicle historical safety operation parameters, calculate the correlation coefficients between the angle change, angular velocity and acceleration by using the correlation analysis method, determine the correlation degree between them, and obtain the correlation analysis result; based on the correlation analysis result, a dynamic coupling relationship is constructed, wherein the calculation formula of the dynamic coupling relationship specifically includes: coupling value Σ= .

[0022] Specifically, the linear relationship between the parameters, i.e. the correlation coefficient, is calculated by using the Pearson correlation coefficient in the correlation analysis method, wherein the value range of the correlation coefficient is between-1 and 1. When the correlation coefficient is close to 1, it indicates that the two variables are positively correlated to a high degree; when it is close to-1, it indicates that the negative correlation degree is high; when it is close to 0, it indicates that there is almost no linear relationship between the two variables. According to the calculated correlation coefficient, the correlation degree between the angle change, angular velocity and acceleration is determined, and the correlation analysis result is recorded. In the calculation formula of the dynamic coupling relationship, the coupling value Σ is an index for comprehensively measuring the state of the vehicle safety operation parameters, which =comprehensively considers the numerical values of the angle change, angular velocity and acceleration, and through the calculation of the square root of the square sum of the three parameters, the parameters of different dimensions are unified into a comprehensive index, which reflects the dynamic characteristics of the overall operation of the vehicle.

[0023] In the implementation process, the specific steps of the data recognition module are: The angle change, angular velocity and acceleration of the current vehicle are collected in real time according to the set sampling frequency by using the gyroscope sensor, and the angle change, angular velocity and acceleration of the current vehicle are filtered to eliminate vibration noise. The load data of the current vehicle is collected in real time by using the pressure sensor, and the load state of the current vehicle is judged in real time by using the pre-set load judgment standard value, so as to determine the specific load state of the current vehicle in the empty load, half load or full load.

[0024] Specifically, in order to accurately capture the dynamic changes of the vehicle during driving, in the embodiment, the sampling frequency is set to be between 100Hz-500Hz, and for example, for a common car driving on urban roads, since the road conditions are relatively good, the dynamic changes of the vehicle are relatively gentle, and the sampling frequency is set to be 200Hz, so that sufficient data can be collected to reflect the running state of the vehicle, and the data volume will not be too large due to too high sampling frequency. For the vehicle driving in complex road conditions (such as mountainous areas, off-road sections), since the vehicle will experience more severe bumps and turns, the dynamic changes are more frequent and complex, and the sampling frequency is appropriately increased to 400Hz-500Hz. The gyroscope sensor generally has three axial (X-axis, Y-axis, Z-axis) measurement capabilities, respectively corresponding to the angle change, angular velocity and acceleration of the vehicle in three different directions. When collecting data, the sensor will continuously output the measurement values of the three axes according to the set sampling frequency. Since the vehicle will be disturbed by various vibration noises during driving, such as engine vibration, vibration caused by uneven road surface, etc., the collected angle change, angular velocity and acceleration need to be filtered, and in the embodiment, the filtering is performed by a low-pass filter. Real-time receive pressure data transmitted by the pressure sensor, and convert these data into corresponding load values. Then, compare the converted load values with the pre-set load judgment standard values, wherein the pressure sensor will continuously collect pressure data generated by the vehicle load. The setting of the load judgment standard value needs to be based on the type of the vehicle, and for example, for a truck with a rated load of 10 tons, the empty state is: when the pressure data collected by the pressure sensor corresponds to a load of less than 1 ton, it is determined that the vehicle is in an empty state; the half-loaded state is: when the pressure data collected by the pressure sensor corresponds to a load of 1-5 tons, it is determined that the vehicle is in a half-loaded state; the full load state is: when the pressure data collected by the pressure sensor corresponds to a load of greater than or equal to 5 tons and less than or equal to 10 tons, it is determined that the vehicle is in a full load state.

[0025] In the specific implementation process, the specific steps of the analysis and calculation module are: According to the identified load state of the current vehicle, the weight values of the angle change, angular velocity and acceleration of the three parameters in the current load state are identified from the parameter weights corresponding to different load states set; the real-time collected angle change, angular velocity and acceleration parameters of the current vehicle are weighted by the weight values of the angle change, angular velocity and acceleration of the three parameters in the current load state, and then the real-time coupling value of the current vehicle is calculated according to the formula in the constructed dynamic coupling relationship.

[0026] Specifically, according to the identified weight values of the three parameters under the current load state, the angle change, the angular velocity and the acceleration parameters collected in real time are weighted, and the calculation formula of the weighted processing is: the weighted angle change value α' = α × angle change weight; the weighted angular velocity value ω' = ω × angular velocity weight; the weighted acceleration value a' = a × acceleration weight. For example, the current vehicle is in a full load state, the angle change weight is 0.4, the angular velocity weight is 0.2, and the acceleration weight is 0.4. Then the weighted angle change value α' = 2° × 0.4 = 0.8°; the weighted angular velocity value ω' = 5° / s × 0.2 = 1° / s; the weighted acceleration value a' = 0.5m / s² × 0.4 = 0.2m / s². After the weighted processing, the weighted parameter value needs to be substituted into the formula to calculate the real-time coupling value, and the formula at this time becomes: real-time coupling value Σ' = √(α'² + ω'² + a'²).

[0027] In the specific implementation process, the specific steps of the evaluation feedback module are: According to the vehicle type and the running condition, the safety evaluation standard is set in advance, including setting the coupling value section corresponding to different safety levels; wherein the safety level includes normal, warning and danger; the real-time coupling value calculated is compared with the safety evaluation standard set in advance, the coupling value section to which the real-time coupling value of the current vehicle belongs is judged, so as to determine the safety level of the current vehicle; according to the determined safety level of the current vehicle, the safety state information of the current vehicle is displayed to the driver through the display device on the vehicle, and the corresponding safety report is generated.

[0028] Specifically, in the embodiment, the coupling value section of the normal safety level is set as (0, 0.3), the coupling value section of the early warning safety level is set as (0.3, 0.6), and the coupling value section of the dangerous safety level is set as (0.6, +infinity). The real-time coupling value of the current vehicle is compared with the coupling value section in the pre-set safety evaluation standard, the coupling value section to which the real-time coupling value of the current vehicle belongs is determined, and the safety level of the current vehicle is determined. According to the determined safety level of the current vehicle, the safety state information of the current vehicle is displayed to the driver through the display device on the vehicle, and the display mode includes: for the normal safety level, a green indicator light is displayed on the instrument panel, and the text information of “vehicle running normally” is displayed on the central control display screen; for the early warning safety level, a yellow indicator light is flickered on the instrument panel, and the text information of “vehicle has potential risks, please pay attention to safety” is displayed on the central control display screen, and can be accompanied by voice prompt. For the dangerous safety level, a red indicator light is flickered on the instrument panel, and the text information of “vehicle is in a dangerous state, please take measures immediately” is displayed on the central control display screen, and is accompanied by urgent voice alarm. In the generation of the safety report, the safety report includes the basic information of the vehicle, the current time, the current position, the safety level, and the real-time coupling value.

[0029] The application realizes personalized safety management by identifying the vehicle type to extract the corresponding standard safety operation parameters and setting the parameter weight based on the load state, accurately matches the vehicle characteristics and adapts to the load change, comprehensively and accurately masters the real-time running state of the vehicle through the multi-parameter comprehensive analysis and the construction of the dynamic coupling relationship considering the parameter correlation, combined with the real-time data acquisition and dynamic evaluation, can comprehensively and accurately master the real-time running state of the vehicle; the deviation threshold section can be set to early warn and prevent safety hazards; the application makes data-driven decisions to form a systematic management process, effectively improves the efficiency and decision-making scientificity of vehicle safety management, provides strong support for ensuring the safe operation of the vehicle, and improves the management efficiency and decision-making scientificity.
