Integration of Mobile Communication and 3S Techniques in Electric Power Monitor System 2.2 Introduction of3S techniques The Remote Sensor, Geographic Information System and Global Positioning System named as 3S is one of the high-developing, abroad application techniques. The 3S techniques give us huge useful information. How to use these data is one of the research realms. 2.3 Realizing the integration of GSM and 3S techniques The integration of GSM and 3S techniques will bring a leap of the application and development of 3S, because they can complement each other in technique. Our system integrates the GSM technique, GPS technique and GIS technique together for satisfying the request of the electric power monitor system. The terminal monitor is made up of the sensor-receiving module, GPS receiving module, central processing unit, and GSM signal sending module. The Control Server is made up of the GSM receiving module, GIS analysis dealing module, Oracle Database Server module, and Internet Information Server module. There is the main running approach of the system (fig.1). The terminal monitor receives the outside information by the sensor-receiving module, gets the position information from the GPS receiving module, and transmits these information to the SCM module. The SCM system encrypts the data and transmits to the GSM sending module. These data are sent to the Control Server through the broad overlay and safe GSM net. The Control Server receives these data from the GSM receiving module. These data is dealt and decoded by the computer, and transmitted to GIS system. Then the GIS system will deal with, display, and analyze the GIS data. Because the data is real-time, these data is stored in Oracle database system real-time. And the Internet Information Server can issue the data, and share it with the world.  Fig.1 The structure of integration system of mobile communication and 3S 2.4 Composing of the system: hardware and software 2.4.1 Hardware system 2.4.1.1 Terminal monitor Differentiated by mobile capability, the terminal monitor includes settled monitor and mobile monitor. As for the hardware, the terminal monitor is made up of the sensor-receiving module, GPS receiving module, central processing unit, and GSM signal sending module. The settled monitor cannot include the GPS module for saving the money. The sensor-receiving module is used to receive the value from outside. GPS receiving module is used to record the position of current monitor. The central processing unit made by ARM chip, is used to deal and encrypt the data that the system received. GSM sending module is used to send the data as the special format that is changed by the central processing unit. 2.4.1.2 Control Server The Control Server consists of the GSM signal receiving module and the PC module. The GSM signal-receiving module is used to receive the data from the terminal monitor. The PC module is the center of the system, in which the GIS system deal with, display, analyze the GIS data, and change, store, and issue the data. The control worker can easily control the whole system running by operating the PC. 2.4.1.3 Database Server Database server of Oracle is used to store the real-time data for further research. 2.4.1.4 Internet Information Server The Internet Information Server use Arc IIS produced by ESRI Company. It is mainly used to issue the data on the Internet, can easily share the data. 2.4.2 Software system 2.4.2.1 SCM operate system SCM operate system adopts the traditional C program language to design. It is mainly used to correspond with the monitor instrumental in the terminal. It receives the environment information from the sensor module and the space position information from the GPS received module, and deals with it. SCM operate system can control the ARM CMOS chip to change the data to a special format, and note the system time and the run state information automatically. |
