Design of Intelligent Vehicle Monitoring System based on μC―OS

Abstract： This paper establishes a set wireless intelligent vehicle monitoring system can be used in car based on S3C2440 and UC-os， including hardware design， software design， system terminal high-speed wireless data transmission and monitoring platform. The experimental results show that the system have high detection sensitivity and high accuracy， and that can effectively prevent drunk driving and theft has very good practical value.

With China’s rapid economic development， the number of cars has make a spurt of progress in the growth， convenient for people to travel， at the same time it also brings various problems. For example， drunk driving， vehicle was stolen. Among them， drunk driving accidents occur frequently， causing serious economic losses and casualties caused by traffic accidents， malignant cases， arch-criminal drunk driving.

In view of the above situation， this paper designs a kind of intelligent identification system based on ucos. This system uses UCOS operating system， take S3C2440 as control system ， embedded MQ-3 alcohol sensor above the front row seat， left and right， acquisition to the alcohol concentration data， through the analysis of fuzzy C- means clustering algorithm[1] to judgment， if not drink and the driver alcohol exceed the standard， and then generate audible alarm and banning cars， at the same time， drunk driving information in real time be send to family and traffic management departments by GPRS. Also， the system can get the vehicle of temperature， humidity， fatigue driving， accident is stolen， parking lock automatically real-time monitoring.

1 Hardware Design

Vehicle monitoring system consists of vehicle terminal， GPRS network and monitoring center is composed of 3 parts， wherein， the vehicle terminal is the key part of vehicle monitoring system. The vehicle terminal can provide navigation， communication， alarm and remote communication functions， hardware is mainly composed of a central processing module， GPS module， GPRS wireless communication module， man-machine interface， the audio module， power supply module components， and system structure is shown in figure 1.

The GPS module of vehicle terminal can receive location wireless carrier satellite signals， after the internal solution to wireless carrier signal is converted into digital information， The central processor of the GPS data analysis， extraction of vehicle dynamic location， time， speed and other information， sent to the GPRS module， through the GPRS wireless network adapter to link the Internet remote data processing center. This establishes a wireless data transmission channel between the monitoring center and mobile terminal， the mobile terminal on the data channel of the vehicle information is transmitted to the monitoring center， the monitoring center can also control command and service information is sent to the terminal through the wireless channel.
