A Study On The Remote Management System Of Physical Parameters

The study use GSM's point to point SMS to project the remote management system of physical parameters,which realize the real time SMS Receiving and Sending,the remote querying of physical parameters,the local management of short Message and physical parameters.At first,the paper analyzes the significance and feasibility of projecting the remote management system of physical parameters,and design the system in general based on user's requirement.Then introduce the key technologies to project the system,they are MSComm Control of PC Serial Communication,AT Command Set for SMS,and the PDU of SMS.And then analyzes PDU to program 7bit codeing and decoding,to design the program of PDU coding and decoding.using the all technologies given above to design the program of SMS Receiving and Sending, Afterward design the system's DataBase based on SQL Server 2000.Use Visual C++6.0 to complete the program of the real time SMS Receiving and Sending and physical parameters querying.At last,the paper introduces the designing of system interface and testing of system running,summarizes the experience in projecting of the system,and put the work that shall be done in future.
