[摘要] 目前大部分的鎖采用的都是機械式的，其最大的缺點是利用簡單工具就能很容易地把鎖打開。針對這種情況，我設(shè)計了一種紅外遙控密碼鎖，而一般設(shè)備都采用專用的遙控編碼及解碼集成電路，其制作簡單、容易，但由于特定功能的限制，只適用于專用的電器產(chǎn)品，其應(yīng)用范圍受到限制。 本設(shè)計由紅外接收頭hs0038（紅外接收頻率為38khz）和STC89C52控制的接收部分構(gòu)成。采用單片機進行遙控系統(tǒng)的應(yīng)用設(shè)計，具有編程靈活多樣，電路結(jié)構(gòu)清晰。整個設(shè)計具有遙控開鎖，本機控制開鎖，密碼修改等功能，可在密碼外泄的情況下及時修改密碼，具有保密性好、安全可靠、成本低廉、連接方便，簡單易用，適用范圍廣等特點，而且特別適合家庭，賓館，倉庫，私家車庫等場所。 關(guān)鍵詞：紅外遙控、紅外接收、單片機、密碼修改
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
