[摘要] 目前大部分的锁采用的都是机械式的,其最大的缺点是利用简单工具就能很容易地把锁打开。针对这种情况,我设计了一种红外遥控密码锁,而一般设备都采用专用的遥控编码及解码集成电路,其制作简单、容易,但由于特定功能的限制,只适用于专用的电器产品,其应用范围受到限制。

  本设计由红外接收头hs0038(红外接收频率为38khz)和STC89C52控制的接收部分构成。采用单片机进行遥控系统的应用设计,具有编程灵活多样,电路结构清晰。整个设计具有遥控开锁,本机控制开锁,密码修改等功能,可在密码外泄的情况下及时修改密码,具有保密性好、安全可靠、成本低廉、连接方便,简单易用,适用范围广等特点,而且特别适合家庭,宾馆,仓库,私家车库等场所。

关键词:红外遥控、红外接收、单片机、密码修改

 

Abstrac:Most of the lock is adopted, the largest of the mechanical faults are using simple tools can easily open the lock. In view of this si tuation, we designed a kind of infrared remote locks, and general equipment adopts remote codingand decoding the special-purpose integrated circuits, its production is simple, easy, but due to the particular function limit, applies only to the product, its special electrical application scope is limited.

  This design by infrared receiving head hs0038 (ir) and 38khz receive frequency for receiving part of STC89C52 control. On the remote control system adopts single-chip microcomputer application programming design, flexible, circuit structure is clear. The design has the remote control of the lock, lock, the password revision and so on the function, may in the circumstance timely leaked password revision password, have good secrecy, safe and reliable, low cost, simple, easy-to-use, and wide application scope, and special features for family, hotel, warehouse, private garage and etc.

Keywords: infrared  remote  control ,  receiving head, SCM, password revision
