Embodiment 1

[0065] A kind of automobile alcohol detection control method, such as figure 2 As shown, the alcohol detection instrument 1, the control device 2 and the ignition control interface of the automobile engine are based on sequential data connections. The OBD II interface 3 of some cars contains an open ignition control interface, which can control the start and stop of the car by sending electrical signals conforming to the OBD II interface 3 protocol, and the OBD II interface 3 also contains speed information. Alcohol detection instrument 1 contains camera. Alcohol detection instrument 1 adopts the alcohol detection instrument disclosed by the Chinese patent that the patent announcement number is CN201220458190.8, and the vehicle-mounted camera that is connected with alcohol detection instrument 1 data to send image data to alcohol detection instrument 1 is set in the car, and vehicle-mounted camera adopts existing The wifi camera available in the market is connected with a wi...

Embodiment 2

[0077] An automobile alcohol detection and control system, the difference from Embodiment 1 is that, based on the alcohol detection instrument 1, the control device 2 and the ignition control interface of the automobile engine connected in sequence, the alcohol detection instrument 1 contains a camera, an alcohol detection module and a computer. The chip is set in the car and is connected to the alcohol detection instrument 1 for data connection. The on-board camera is used to send image data to the alcohol detection instrument 1. The calculation chip includes:

[0078] The calling unit is connected with multiple cameras data, used to call the camera and read the image data in the camera, and connect with the alcohol detection module at the same time to read the alcohol data;

[0079] The comparison unit is connected with the data of the calling unit, internally stores the comparison image, and matches the image data according to the comparison image to obtain a feature code; ...

Abstract

The invention relates to the technical field of alcohol detection, and discloses an automobile alcohol detection control method and system thereof, wherein the method includes, based on sequentially connected alcohol detection instruments, a control device and an OBD II interface, comprising the following steps: Obtain alcohol data and image data; match the image data with the comparison image to obtain a feature code, and send the feature code and alcohol data to the control device; the control device compares the alcohol data with the comparison data and matches the alcohol inspection code, alcohol inspection code and signature Both include compliance codes and non-compliance codes that appear at different times; the control device sends image data, feature codes, and wine inspection codes to the management background for storage and backup; the control device sequentially controls the ignition control of the car engine in series according to the alcohol inspection codes and feature codes Interface; while performing alcohol detection, it also monitors whether the driver has changed throughout the process, prevents the driver from cheating and bad behavior, and stores backup data at the same time to increase the reliability of the record.

Description

technical field [0001] The invention relates to the technical field of alcohol detection, more specifically, it relates to an automobile alcohol detection control method and a system thereof. Background technique [0002] Driving safety has always been a key issue in the transportation field. Drunken driving has always been a repelling behavior in the driving field. Therefore, many on-board alcohol detection instruments have been produced, and the current on-board alcohol detection instruments are also becoming mature. [0003] In the prior art, the car alcohol detection lock is to electrically connect the alcohol detection instrument to the OBD II interface of the car control interface through a control device. functions such as speed. The control device can read and record the data in the OBD II interface. [0004] At present, the control device of the car wine detection lock judges whether the car is started by detecting the collapse of the voltage at the moment of star...
