Aystem of remotely operated terminal based on CAN bus and DSP

In allusion to the problem of the serial communication pattern in power remotely operated terminal system and the poor ability in measuring parameters not to satisfy the transmission of real-time data,the design and realization of power remotely operated terminal system in substation based on CAN bus and DSP is introduced in this paper.In the system DSP is used to measure electrical parameters to enhance the ability of real-time response and signal process.And CAN integrates merits of flexible and simple structure,high reliability and easy maintenance.The functions of measuring the power parameters,harmonious analysis and event record are also involved in the system.So the system can satisfy the need of the development in power remotely operated terminal system.
