The Design Of Distributed RTU System

A distributed RTU device based on microcompture interflow sampling method is designed in this paper. At first it simply introduces the significance of supervisory control and data acquisition in the current net system automation and the development condition of RTU. The practical prospect and research purport are also probed into in this paper. Then it summarizes the integration layout thinking of the distributed RTU. It also discusses the design of reliability of RTU and provides many anti-interfere methods in accordance with the actuality circumstance. And then it expounds the sampling method of RTU and the communication technology problems. At last, it analyzes the structure of hardware and the key circuitry using 80C196KB single-chip computer, and simply introduces the scheme and ideology of software and flow chart of the principally software.
