The Design And Implementation Of A Wireless Remote Monitor System Based On SMS

This dissertation introduces a system which implements monitoring applications in manner of wireless and remote.The target of monitor is a running application software of Windows operation system. The system can watch out dialog boxes of the applications through hook technology, communicate with users by SMS, and control the application's running by simulating button click.This dissertation first introduces and analysises related technologies, including SMS, Windows message mechanism and hook technology. Second, the dissertation gives the purpose of design and the solution. Then it describes the components of system and the main funcation. Third, the dissertation introduces the methods of receiving and sending SMS with GSM modem. Third, the dissertation introduces the design of monitor module and describes in detail how to implement hook message unit, control unit and simulation event unit. Last, the dissertation shows how to use the system by example. Then it brings forward some farther suggestions of improvement.Based on the prototype, we can develop a valueable application system. The author believes that the hook technology and the simulation method applied in our system should be helpful to the developers in related field.
