The Design Of Intelligent Monitoring System Based On GSM Network

With the development of modern communication technology, GSM mobile communication hasa very wide range of applications, the GSM short message system which based on the TDMAtechnology is more mature, improve, and get an extensive application. GSM short messages can bemade into various functions such as transport a wide variety of testing, monitoring, datacommunication signalling and control command system, widely used for remote monitoring, GPSnavigation, and other personal communications terminal areas.The paper proposes a remote intelligent monitoring system based on GSM network anddesigns the hardware and software work after designing the system process.PC monitoring center, MCU, peripheral interface circuits and GSM communication modulewhich used to releate PC and MCU are builted for this system which uses GSM network as awireless remote data transmission platform, and then highlighted the relative importance of thissubject of GSM network short message communication principles.In the design of the hardware, MSP430F149 with huge internal resource and ultra-low powercharacteristics is used as the CPU, MCU and GSM wireless communication module produced byGermany’s Siemens company, are used to send and receive short messages.The whole hardwarestructure can be divided into the host computera part and the MCU peripheral interface part.Thehost computer is a simple part, includes a PC and GSM module TC35, both through the RS232serial port connection,MCU and peripheral interface part include TC35 communications module,LCD liquid crystal display unit, a variety of sensors data acquisition and processing units.In system software design, PC software using the Visual Basic 6, adding MSComm ActiveX,to complet the computer interface, and deal the standard AT command. In the design of MCU andperipheral interface, using IAR EW430 integrated development environments and c languagedebugger as the MSP430 microcontroller program development and debugging tools, its softwareprogram includes system initialization, interrupt signal acquisition and A / D conversion process,short message sending and receiving and so on.The last part of the thesis, this system using GSM short message networks as a wireless dataconnection base, combined with the ECG abnormal alarm monitoring, designde of the system basedon GSM short message network to realize the remote ECG monitoring. After experimentally tested,the system runs stable, live strong, achieve the desired result. Compared with conventional ECGmachine, not only by low power consumption, small size, simple operation and easy to carry, butalso greatly reduces the cost of ECG monitoring system. The system have some practical value.
