Design And Implementation Of A Vehicle Monitoring System Based On GPS And GSM

With the progress of the society and improvement of the economy, the quantity of vehicles keeps increasing. However, the development of the road construction has fallen behind the incensement of vehicle, which causes a serial of serious society problems such as more and more traffic-jams, accidents and so on. For the sake of the whole society, we must take measure to resolve the problems mentioned above.ITS(intelligent traffic system) is a new technology field that com.es into being, as soon as more and more electronic technology and communication technology were applied in traffic control. From the viewpoint of system theory, ITS considers four factors: people, road, vehicle and environment, synthetically. It comes up with many solutions in order to reduce the occurrence of traffic-jams and accident. Further more, ITS has become an important tendency of modern traffic engineering.In order to put theory into practice, the author researches many theories and application of ITS and vehicle monitoring system. The research work achieved, during the course of author completing the paper, is discussed in detail as follow.Firstly, this paper discusses the basic theory of ITS and analyzes its development both domestically and overseas. On the other hand, this paper expatiated the academic content of ITS at present from the viewpoint of academic research and studied the systemic frame of ITS from the viewpoint of systemic engineer. Based on all the research work mentioned above, the paper pointed out some ITS solutions which are effective to resolve some traffic problems.Secondly, intelligent vehicle monitoring system is a typical application of ITS in traffic control and management. The paper discusses the basic theory, systemic structure and systemic function of the intelligent vehicle monitoring system. The paper also analyzes the related key technology of this system such as CIS, wireless position technology, wireless communication etc.At last, this paper discusses the designation and implementation of a GPS/GSM vehicle monitoring alarming system. This system produces a practical measure to resolve the problems in traffic control and management, such as vehicle hijacking, vehicle safe, vehicle management discommodiously. This GPS/GSM vehicle monitoring alarming system adopts GSM SMS as data traffic means. It.can offer the following functions: Onone hand, users can query both the position and the state of the vehicle. On the other hand, the vehicle can send the help signal to the vehicle monitoring center while the vehicle encounters traffic accident or the vehicle is hijacked. According to the help signal, users and vehicle monitoring center can dispose the accident at time. This GPS/GSM vehicle monitoring alarming system can be applied in TAXI, goods circulation and private vehicle etc. This system also produces a method to enhance the vehicle management and the ability of vehicle safe. The system has experienced practical test and achieved expectant result.
