Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] see figure 1 , is a system structure block diagram of the embodiment of the present invention. This system adopts AT89C52 central processing unit, its input end is connected with anti-drinking driving module, anti-fatigue driving module and bad weather navigation module, and its output end is connected with voice prompt module, liquid crystal display module and start control module, among which, start control The module interfaces with the car's engine start system.

[0025] see figure 2 , The anti-drinking driving module includes a pressure sensor JHBM-7 installed on the driver's seat and an alcohol detection sensor TGS822 installed in front of the driver's seat, both of which send signals to AT89C52 through the analog-to-digital converter ADC0809. This module detects the alcohol concentration of the driver's exhaled gas through th...

Abstract

The invention belongs to the technical field of automatic control, in particular to a multifunctional intelligent vehicle start and safety protection system. The system comprises a central processor, wherein the input end of the central processor is connected with a drunk driving prevention module, a fatigue driving prevention module and a severe weather navigation module, while the output end is connected with a voice prompt module, a liquid crystal display module and a start control module, and the start control module is connected with a vehicle engine start system; the drunk driving prevention module comprises a pressure sensor and an alcohol detection sensor which are connected to a CPU (Central Processing Unit) through a signal amplifier and an analog to digital converter; the fatigue driving prevention module comprises a timer, and the timer is started along with the start of the vehicle through the CPU; the severe weather navigation module comprises an ultrasonic distance measuring module; and the ultrasonic distance measuring module and a vehicle speed information output end are together connected to the CPU. The invention can effectively and originally suppress traffic accidents and has the advantages of good compatibility and strong realizability.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a multifunctional vehicle intelligent starting and safety protection system with the functions of preventing drunken driving, preventing fatigue driving and navigating in bad weather. Background technique [0002] Today, with the continuous increase of vehicles, traffic accidents have become "the world's number one hazard", and China is the country with the largest number of traffic accident deaths in the world. Since the end of the 1980s, China (excluding Hong Kong, Macao and Taiwan) traffic accident death toll has ranked first in the world for more than ten consecutive years. Although, China's car ownership only accounts for 3% of the world's total, while traffic accident deaths account for 16% of the world's. According to the Traffic Management Bureau of the Ministry of Public Security, in 2009, there were 238,351 road traffic accidents across the countr...
