Design And Implementation Of SMS Sending And Receiving System Based On Q2358C

Because of its lower cost, wireless transmission characteristics and good real-timeperformance, short message service has found widespread applications. If themessage sending or receiving is only used by single phone, it would be complex tooperation and waste of time, and this mode don’t apply to the high frequencygroup-sending services. This existed problem can be solved effectively by usingmessage sending and receiving platform.This thesis design a sending and receiving system of short messaging which isbased on the Q2358C. Firstly,The Q2358C module of hardware is introducedincluding the system of basic working principle and key techniques. Then, the systemrequirement analysis is made, emphasis is put on the viewpoint of the functionality..Finally, the system is implemted through the hardware installations of the Q2358C,DLL design and implementation, database design,and system interface.The main work of this thesis includes：1.A dynamically link library is designed and implemented, and this is the keypart of the system. This part includes using the control SPCom to realize thecommunication between of the computers and wireless terminals, using AT instructionsto realize various control for the sending and receiving of SMS module, and usingUnicode encoding to complete the messages encoding, decoding and accessing toterminal messages database access.2.Aiming at the user’s requirement, the systerm uses Access database for the datastorage. It got a lot of freedom for t the information management ‘s access.3.As an important part of SMS sending and receiving systerm, the design ofinterface will directly influence the user sensation. Users can finish the receiving andsending text through the friendly interface. The interface implemtattion is also given..4.Finally, the commissioning of the SMS management platform‘s hardware andsoftware system is presented. The test shows that the system’s work is stable, accuracyand available.With the development of science and technology, SMS sending and receivingsystem will get more and more application. Its function is being perfected and theapplication of the computer industry will be more and more wide. Due to the haste,the system’s design and implementation may has many defects, and we hopr toupdate and improve it in the future.
