The design of intelligent electronic relay based on AT89C52 single chip microcomputer

摘要

Using AT89C52 single chip microcomputer to complete the design of the intelligent electronic timing relay, not only can well realize the arbitrary set of time, but also can be accurate to milliseconds. This design from the total block diagram of hardware design, described the design of hardware and software in detail, and gave the design of the circuit principle diagram, hardware diagram and program code.
