摘要
电子密码锁是一种通过密码输入来控制电路或是芯片工作,从而控制机械开关的闭合,完成开锁、闭锁任务的电子产品。它的种类很多,有简易的电路产品,也有基于芯片的性价比较高的产品。现在应用较广的电子密码锁是以芯片为核心,通过编程来实现的。其性能和安全性已大大超过了机械锁,特点如下:
1.保密性好,编码量多,远远大于弹子锁。随机开锁成功率几乎为零。
2.密码可变。 用户可以经常更改密码,防止密码被盗,同时也可以避免因人员的更替而使锁的密级下降。
3.误码输入保护。当输入密码多次错误时,报警系统自动启动。
4. 电子密码锁操作简单易行,一学即会。

Abstract
Electronic Code Lock is a password input through the control circuit, or chip, thus controlling the closed mechanical switch to complete the lock, closed the task of electronic products. It is of many types, have a simple circuit products, but also the higher cost chip-based products. Now the widely used electronic code lock is a chip at the core, achieved through programming. Performance and safety have greatly exceeded the mechanical lock, the following features:
1. Privacy is good, coding quantity is far greater than the spring lock. Random unlocking success rate is almost zero.
2. Password variable. Users can always change the password, to prevent password theft, but also avoids the lock because of staff turnover Er Shi and drawing down.
3. Error input protection. When you enter your password wrong several times, the alarm system started automatically.
4. E-lock operation is simple, a school that will.
