Description

System for real-time detection of driver's alcohol content and detection method based on the system

technical field

The invention relates to a system and method for detecting alcohol content.

Background technique

At present, the method for the driver's alcohol content at home and abroad is to let the driver blow to the collection part of the alcohol detection equipment to realize the alcohol detection. If air is blown as required, accurate detection cannot be achieved smoothly. On the other hand, this method can only conduct targeted random inspections by designated personnel, and the operability of large-scale inspections is poor, and the real-time performance is poor, and the early warning rate before accidents is extremely low.

Contents of the invention

In order to solve the problem of poor real-time performance of the existing method for measuring the driver's alcohol content, the present invention provides a system for real-time detection of the driver's alcohol content and a detection method based on the system.

A system for detecting the driver's alcohol content in real time during vehicle driving, which includes an alcohol sensitive element, a signal amplification and processing unit, a vehicle travel recorder vehicle terminal, an identification unit, a wired signal transmitting unit and a wired signal receiving terminal, the alcohol sensitive The component is used to detect the alcohol content in the environment where the system is located. The alcohol detection signal output terminal of the alcohol sensitive component is connected to the signal input terminal of the signal amplification and processing unit, and the signal output terminal of the amplification circuit is connected to the vehicle terminal of the vehicle travel recorder. The alcohol detection signal input terminal of the vehicle travel recorder is connected; the identification signal output or input terminal of the vehicle travel recorder vehicle terminal is connected with the identification signal input or output terminal of the identity recognition unit; the wired communication signal of the vehicle travel recorder vehicle terminal The output end is connected to the input end of the wired signal transmitting unit, and the signal output end of the wired signal transmitting unit is connected to the signal input end of the wired signal receiving terminal.

The method for detecting the driver's alcohol content in real time during vehicle running based on the above-mentioned device, it is realized by the following steps:

Step 1. The on-board terminal of the vehicle travel recorder identifies the identity of the person in the vehicle through the identity recognition unit. When it is recognized that the person in the vehicle has a driver, the on-board terminal of the vehicle travel recorder reads the information of the alcohol sensitive element located in the driving position of the vehicle. Signal;

Step 2. The vehicle-mounted terminal of the vehicle travel recorder judges whether the alcohol content in the driving seat of the vehicle exceeds the standard. If the judgment result is yes, the vehicle-mounted terminal of the vehicle travel recorder will detect the result of exceeding the standard and output the detection signal to the wired signal receiving unit through the wired signal transmitting unit. The terminal realizes the detection of the alcohol content of the driver; if the judgment result is no, the detection result of the vehicle driver is qualified, and the detection at the current moment is ended, and then returns to step 1 to perform the detection at the next moment.

A warning module is used to give a warning to the detection result exceeding the standard obtained in step 2.

The memory is used to store the detection result exceeding the standard obtained in step 2.

Using the wireless signal transmitting unit and the wireless signal receiving terminal to wirelessly output the detection result obtained in the second step.

The alcohol detection database is used to store the wireless output detection results exceeding the standard.

Beneficial effects: when the system of the present invention is actually used, the alcohol sensitive element in the system is installed in the driver's seat attachment in the cockpit to detect the alcohol content of the driver's position in the cockpit, and, when judging by identification When there is a driver in the driver's seat, the information collected by the alcohol sensor is judged, and then indirectly judged whether the driver is drinking to realize the detection. The present invention detects the alcohol content in the air near the driver in the cockpit, without the cooperation of the driver to blow air on the detection instrument, as long as the driver breathes normally in the driver's seat, the alcohol concentration in the air in the cockpit can be reduced. Change occurs, and this system can judge whether the driver's alcohol content exceeds the standard according to the alcohol concentration in the air in the cockpit. The invention completely avoids the problem of inaccurate detection caused by the lack of cooperation of the driver, and has strong real-time performance. Real-time detection can be started when the driver sits in the cockpit, and the early warning rate before the accident is greatly improved.
