The drunk driving limiting system based on the finger vein characteristic judgment comprises a finger vein vessel diameter information calculating unit, a finger vein vessel diameter information calculating unit and a finger vein vessel diameter information calculating unit, wherein the finger vein vessel diameter information calculating unit calculates the ratio of the vessel diameter variation to the vessel original diameter and converts the ratio into an evaluation value P1。
The drunk driving limiting system based on finger vein characteristic judgment refers to the instantaneous flow speed information of the blood in the finger vein, and comprises the steps of calculating the ratio of the flow speed variation and the original flow speed value, and converting the ratio into the evaluation value P2。
According to the drunk driving limiting system based on finger vein characteristic judgment, finger vein blood reflection infrared spectrum information comprises a spectrum which is compared and detected with a pre-stored spectrum, and the gray change rate of the spectrum is converted into an evaluation value P3。
The drunk driving limiting system based on finger vein feature judgment is characterized in that each evaluation value is in percentage system, and a weighting processing formula is P-P1x0.3+P2x0.15+P3x0.55。
And the threshold value is 70 according to the drunk driving limiting system judged based on the finger vein characteristics.
According to the drunk driving limiting system based on finger vein feature judgment, the finger vein information acquisition assembly comprises an image and video acquisition module and an infrared light reflection imaging module.
The invention needs to collect finger vein information of user in normal state in advance, including finger vein infrared photo, blood flow speed of finger vein in detection time period, and atlas of infrared light source reflected by finger vein, and stores these data. During detection, the information is collected and compared with prestored information, the variation is calculated through software, the score value is determined according to the variation, final scores are determined according to different weights for various indexes, and the user can be determined to drink when the final scores exceed a certain threshold. Thus, vehicle start-up is prohibited.

Detailed Description
The invention is realized in such a way, please refer to fig. 1 and combine with fig. 2, a drunk driving limiting system based on finger vein feature judgment comprises a finger vein feature acquisition module and an identity verification module, wherein the finger vein feature acquisition system comprises a finger positioning component 1 with a touch sensing component, an infrared light source 2 positioned on one side of the finger positioning component, and a finger vein feature judgment module, wherein the finger vein feature judgment module is loaded with a program for realizing the function of judging whether to drink or not according to the finger vein feature, the finger vein feature acquisition system further comprises a finger vein feature acquisition component, the acquired features are further processed by the finger vein feature judgment module to obtain a judgment result besides identity verification, and if the judgment result is that the vehicle is drunk, the vehicle control system is prohibited from starting the vehicle.
The drunk driving limiting system based on finger vein feature judgment comprises a finger vein vessel diameter information calculating vessel diameter change rate and converting the finger vein vessel diameter change rate into an evaluation valueP1。
The drunk driving limiting system based on finger vein characteristic judgment refers to the instantaneous flow rate information of finger vein blood, comprises the steps of calculating the change rate of the flow rate and converting the change rate into an evaluation value P2。
According to the drunk driving limiting system based on finger vein characteristic judgment, finger vein blood reflection infrared spectrum information comprises a spectrum which is compared and detected with a pre-stored spectrum, and the gray change rate of the spectrum is converted into an evaluation value P3。
The conversion of the evaluation value of each finger vein information can be performed according to the following table:
watch (A)
The drunk driving limiting system based on finger vein feature judgment is characterized in that each evaluation value is in percentage system, and a weighting processing formula is P-P1x0.3+P2x0.15+P3x0.55。
The finger vein information is used for judging whether to drink, and the threshold value is 70. If the calculation result is more than or equal to 70, the tester can be judged to be drunk.
The invention relates to a system for limiting drunk driving and abnormal emotion driving based on finger vein characteristic judgment, wherein a finger vein characteristic judgment module can be integrated in a vehicle master control system, the module is loaded with a program for realizing the function of judging whether drinking or not by finger vein information, the finger vein information acquisition system comprises a finger positioning component with a touch sensing component, an infrared light source and a finger vein information acquisition component which are positioned on one side of the finger positioning component, the acquired information is processed by the finger vein information judgment module to obtain an evaluation value, and if the evaluation value exceeds a threshold value, the vehicle control system is prohibited from starting a vehicle and playing prompt voice.
