Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments. Such as figure 1 As shown, the present invention includes microcontroller, acceleration sensor, alcohol sensor, AD converter, GSM module, power supply part, LCD screen and speaker. The alcohol sensor is connected to the AD converter, and the voltage signal caused by the alcohol concentration in the air is transmitted to the AD converter in real time, and the AD converter converts the analog signal into a digital signal. The acceleration sensor obtains the acceleration information in four directions of the car, front, rear, left, and right in real time. AD converter and accelerometer through I 2 C bus hooked up to the microcontroller's I 2 C interface, the microcontroller through the I 2 The operation of the C bus to read the data obtained by the alcohol sensor and the acceleration sensor. The GSM module is connected to the microcontroller through the serial port and ...

Abstract

The invention relates to a dangerous driving prevention device for automobiles. An acceleration sensor and an alcohol sensor are simultaneously used for acquiring automobile data in real time, so that the device can identify various automobile dangerous driving movements. The danger coefficient is accumulated to make statistics on the traveling danger level, thereby effectively reducing the false alarm rate; and the short message and telephone functions of sound, LCD display and GSM modules are used for warning and preventing dangerous driving without modifying the automobile, so the prevention mode is more humanized. The invention has the advantages of simple structure, convenient installation and strengthened function, effectively prevents dangerous driving in a more humanized mode, and facilitates the market popularization.

Description

technical field [0001] The invention relates to an intelligent electronic device for automobiles, in particular to an automobile anti-dangerous driving device. Background technique [0002] According to statistics, as of March 2010, the number of motor vehicles in my country was nearly 192 million, and there were about 205 million motor vehicle drivers in the country. Cars have entered our lives as a common consumer product, bringing many conveniences to our travel. However, according to statistics from the Ministry of Public Security, in 2008, there were 265,204 road traffic accidents across the country, resulting in 73,484 deaths, 304,919 injuries, and direct property losses of 1.01 billion yuan. [0003] It is understood that most of the causes of traffic accidents are human factors. Because some people have weak safety awareness and ignore road traffic regulations, they often accidentally lead to tragedies. [0004] At present, the known anti-dangerous driving devices h...
