Research On The Mobile Monitoring Terminal Technology Of Vehicle Operation Status Base On Embedded Qt System

The rapid development of the modern logistics industry puts forward higher requirements for vehicle monitoring systems.The traditional vehicle monitoring system adopts a web monitoring mode with a fixed location of the monitoring center,which is not suitable for vehicle monitoring and management of medium-and-small sized logistics enterprise,because it is impossible to view the vehicle operating status anytime and anywhere in a mobile environment,and the cost of system development,operation and maintenance is very expensive.To handle this problem,this paper developed a portable mobile monitoring terminal system,and the main research contents and technical results are as follows:1^st.The technical background and development status of mobile monitoring terminals are analyzed,the design goals of portable mobile monitoring terminals is determined,and studies the information flow and corresponding relationships in vehicle operation monitoring of logistics enterprises.Aiming at the vehicle operation monitoring requirements of medium-and-small sized logistics enterprise,a solution for vehicle movement monitoring system for these enterprises is proposed,which is based on embedded Qt technology,Sqlite relational database technology,wireless communication network technology and graphical interface terminal technology.2^nd.In order to obtain the information of the moving vehicles,such as the location and the temperature and the humidity,the vehicle operating status collection terminal module is designed,and the software and hardware design of portable mobile monitoring terminal module are given,then the above information of multiple vehicles is transmitted to the portable mobile monitoring terminal through the wireless communication network,so that it can be stored in the designed related database.Moreover,by using the Qt graphical interface development technology,a multi-functional operation interface for the portable mobile monitoring terminal is designed to display the vehicle operating status information in real time.3^rd.The system test scheme is designed,and the joint debugging of system's software and hardware is completed.Finally through simulating the actual vehicle condition environment,the system test of the mobile terminal's vehicle operating status collection,and portable mobile monitoring terminal data management and display are completed.The test results show that the vehicle operating status collection terminal can complete real-time extraction of vehicle status information such as vehicle position,temperature and humidity in the vehicle,and can transmit it to the portable mobile monitoring terminal in real time which can real-time and accurate display these information.And it shows that the designed portable mobile monitoring terminal system is feasible,and its operation is effective,which can satisfy the needs of vehicle monitoring and management of small and medium-sized logistics enterprises.These research work and results have great significance and reference value for the popularization and application of mobile monitoring terminal.
