【Abstract】 A new intelligent time relay was designed based on PIC16F877 single chip. Its eight channels can calculate the time at the same. It has ten operation modes, four delay time segments and two calculating time modes (at positive or negative direction). It has characteristics setting remembering, LED real-time displaying, serial communication, in circuit debugging, in circuit programming and other traits. The remoter controller, infrared receiving and infrared transmitting technologies are introduced into the relay protecting industry at first. The characteristics can be set and consulted conveniently and reliably. This makes the hardware of the equipment simpler. Its digital, intelligent and network characteristic, simplified hardware framework and rational software design made it have powerful competitive power in the market.更多还原
