The design of infrared remote control code lock
Abstract: The design of infrared remote control code lock is in the central of processing unit, from the launch of programming AT89C51 and AT89C52 control circuit to receive parts, short-range infrared remote control technology and electronic code lock system technology solutions, hardware design is given circuit and software architecture, system hardware described in detail the design features of lines and structures, as well as the design features of the software at the same time gives the flow chart of each and every major subroutine, remote control from up in the indoor 14m, outdoor is also up to more than 10m circuit by the high stability and decoding accuracy, efficiency.
Keywords: code lock; single-chip; infrared remote control
