Mobile Terminal Based On Embedded Technology Design

GSM network has been developed for many years and is fully-fledged. It has many advantages, such as wide coverage, many users, and can develop a variety of value-added business. So GSM communication has been an important aspect of the mobile communication, and is valued by communications equipment manufacturers, ICP and telecommunications operator. At the same time, in recent years, embedded technology make tremendous progress, and is widely applied in communications, automotive, aerospace, consumer products and many other area which are closed related to the life. The combination of the mobile communication and embedded technology will have a good prospect.In recent years, the integrated application of the industrial monitoring and communication technology has been much more widely used, and with the help of the necessary communication technology, it can collect distal industrial equipment information which is transmitted to the monitoring center. Now there are many forming related technologies, such as achieve information network transmission through the network cabling, but this method has many disadvantages, for example, pre-wiring is complex, investment is enormous, installation is inconvenient. Based on the disadvantages of the method and the related inconvenience, according to the background that the data which is collected from the industry control scene is needed to timing return to the control center, we use the method that combine GSM technology with embedded technology, and design the system. Using GSM technology can achieve data transmission better, and under non real-time system and few data circumstance, cost performance is well, and using embedded technology can achieve the feature that the module is compact and special, and the price is appropriate, and it has practical application of good value.The main task and the achievement in this thesis include:First, achieve GSM module's communication function. Through the way of short message communication, complete information exchange between the client and the console.Second, use the EVC in embedded system WINCE to complete information transmission.Third, design good operation interface. Operation interface supply man-machine interaction contact function, receive the user's input, display the output result. Also, it supplies the interface between the control of the mobile terminal system and the connection between mobile terminal and user. Its function mainly includes: user keyboard input, the display of the mobile termination state and the send and receive information process, the management of the telephone book.Fourth, take the reliability of news transmission, the secrecy in transmission process as well as certain error correction ability into consideration. Realize and complete some function of the application program in the system.
