Embodiment 1
[0056] This embodiment provides a flow chart of a method of using vehicle conditions and physiological parameters for traffic early warning, as shown in figure 1 Shown: including the following steps:
[0057] S1: Acquiring a first parameter in real time, the first parameter including a driver's physiological parameter;
[0058] Obtaining a second parameter in real time, the second parameter comprising a real-time vehicle condition data parameter;
[0059] S2: Establish a coordinate system with the acquisition time as the abscissa, and the acquired first parameter and the second parameter as the ordinate;
[0060] S3: Within the range of the abscissa [0, T], divide it into several equal time periods for the following analysis:
[0061] S31: Obtain the Hurst exponent H of the first parameter by R / S analysis method BIO and the Hurst exponent H of the second parameter OBD ; When the Hurst exponent H of the first parameter BIO and the Hurst exponent H of the second parameter ...
Embodiment 2
[0089] This embodiment provides a system for traffic early warning using vehicle conditions and driver physiological parameters, which has a one-to-one correspondence with vehicles, such as image 3 As shown, it further includes:
[0090] The first data acquisition module: used to acquire the physiological parameters of the driver;
[0091] The second data acquisition module: used to acquire real-time vehicle condition data parameters;
[0092] Data synchronization module: synchronize the physiological parameters in the first data acquisition module with the vehicle condition data parameters in the second data acquisition module on the time axis;
[0093] Analysis and judgment module: used to divide the time zone [0, T] into several equal time periods for the following analysis:
[0094] Using the R / S analysis method to obtain the Hurst exponent H of the first parameter BIO and the Hurst exponent H of the second parameter OBD ; When the Hurst exponent H of the first parame...
