摘要
随着人民生活水平日益提高科学技术的不断发展,人们对 财产以及资料的安全保密要求也在不断的提高,设计出一款拥有 较高的安全性能的保险箱已成从事电子行业人员的一项重要任 务,保险箱的设计应该改进以往的设计思路,增加多项功能使其 更安全更人性化,为满足人们对保险箱的使用要求,增加其安全 性,用密码代替钥匙,并且增加报警功能的保险箱应运而生。电 子密码装置无论在技术上还是在性能上都有了大大的提高,从而 使保险装置的安全性、可靠性得到大幅度的提高、应川口益广泛, 人民对保险装置的需求得到满足。一下所介绍的电子保险箱报警 器釆用AT89C51单片机控制、AT24C02存储、1602液晶显示,4 X4矩阵键盘输入密码。该保险箱报警器具有安全性高、成本低、 功耗低、易操作等优点。
Abstract
As people's living standards are improving the continuous development of science and technology, people's property and the security and confidentiality of information requirements are also constantly improve, designed with a higher safety performance safe has become engaged in the electronics industry professionals is an important task, safe design should be improved the previous design thinking, increase the number of function to make it safer and more humane, to meet people on the safe use of requirements, increase its security, password instead of keys, and increase the safe emerge as the times require alarm function. Electronic cipher device both in technical or performance has been greatly improved, so that the safety device safety, reliability is greatly improved, application is increasingly wide, people on the insurance device needs are met. It introduced the electronic safe alarm controlled by AT89C51, AT24C02 storage, 1602 LCD, 4 x 4 matrix keyboard input password・ The safe alarm has high safety, low cost, low power consumption, easy to operate・
