Software REalization Of Real Time Wireless System Of Remote Control And Remote Measurement

The system of SCADA (Supervisory Control and Data Acquisition) is the Telemetering and Telecontrol system. The third generation of SCADA, based on the technology of distributing computer net and relation data Base, could realize the large-scale Internet connection, which is currently applied in data collection, surveillance control and processing control in the fields of electric power system, water supply system, Petroleum and chemical industry etc. The fourth generation of SCADA would adopt the Internet technology, Object Oriented Technology, Neural Network as well as JAVA technology as its main development tendency, aiming at enlarging the integration of SCADA and other systems, which could finally meet the needs of business management and integrated security economic circulation.According to the trend, this paper introduces the technology of database and PC's Serial Port Communication, which is adopted as the technology premise of wireless surveillance control system. And it illustrates the key technologies of how to realize the wireless surveillance control system. By making full use of its possible expansibility, flexibility and pervasive applicability, as well as the Serial Port Communication technology, SCADA could help to transmit batch of data effectively, extend the ASCII code Serial Port Communication processing in the MSComm components and transmit the large-scale data stream. The author puts forward more suggestion of how to further improve the finished system with his own appraisement.
