The Research Of The Communication Between The PC And Mobile Phone Based On GPRS/GSM Module

Remote Monitoring and Control System (RMCS) has been widely used in the area of Security Monitoring, manufacture Process Monitoring and community Monitoring. More and more users are interested in RMCS because of its remote Monitoring. With the rapid development of communications technology, by using existing GSM network resources, taking the advantage of wide covering, good transmitting characteristics, a convenient wireless data transmission method has been put forward for present data collecting system. This shows the trend in the field of industrial control and live monitoring. In the case of monitor and control field transmitting a little amount of data amount, people can utilize short message service (SMS) in GSM networking directly to transmit data in order to realize wirelessly remote monitoring and controlling.The article describes the development of a control center in the Visual C++6.0 environment In order to achieve communication between PC and mobile phones.Only in the control center, Users can achieve wireless remote monitoring and control for all of the controlled object,Making the monitoring task much more convenient. And the monitoring center is designed In accordance with the the requirements of the Chinese, So users can operate in the way of pure Chinese,The port is defined in Chinese by user,Mobile phone call to the monitoring center in the form of Chinese SMS,Feedback from control center to the user is also a Chinese.The system uses wireless module MC35I produced by Siemens company,It is mainly used to receive and send short message.Module is connected with the PC via a standard serial port RS232, Users can edit the content in the monitoring center,Then send it to the recipient phone via the module. Short messages can also be sended to the PC through the serial port in the form of Chinese from the mobile phone, It completes communication between the phone and the PC in pure Chinese.In this paper, completing the following work:It achieves Chinese communications between PC and mobile phone using of digital mobile communications short message, No longer need to input AT commands and string of PDU when sending text messages.It analyzes and studies the structure of the message, the process of sending etc. studies the SMS PDU format and codec.It Completes realization of the compilation and debug of send and receive text messages process In the PC under Windows system VC++6.0. Complete realization of the compilation and debug of send and receive text messages process In the PC by directly read and write RS232 serial port.
