The Design Of RTU's Communication Software

Based on the CDT protocol and the architecture of hardware , the software which makes use of simple , effectual algorism and assemble language implements the communication of RTU, it completes the data's operation, recordation, organization and supervision and it also fulfils the request of real-time and veracity of the system . RTU has many functions . It not only organize and send telesignal data, telemetering data, pulse counter data and frequency data etc to the main station but also receive the command of main station to implement telecontrol and teleadjusting according to the protocol . It makes the system run safe. This paper describes the algorism of CRC check and the algorism we adopted improves the veracity of data and the efficiency of system . The system provides local display function which make it easy to install and debug , and it is also one of the characters of our system . It was proved that the system can run safe according to the protocol and it promotes the development of electric power supervisory automation in our country .
