DESIGN OF INTELLECTUALIZED ELECTRICAL APPARATUS

Intellectualized electrical apparatus is a new generation of electrical switches, which synthesizes microcomputer technology, digital processing technology and network communication technology. They have some basic functions, such as microcomputer measurement, microcomputer protection, communication and on line monitoring. In this paper, the implementing methods for intellectualized electrical apparatus are discussed. The structure of hardware system is provided. The principles of various circuit units are introduced, i.e. the single chip microcomputer system, the data collecting system for analog signals, the I/O circuit for switch quantity, the interface circuit for serial communication, the circuit for hardware clock and self restoration, and the man machine conversation module. The algorithm for microcomputer measurement and protection are offered.
