摘要
随着当前人们经济的发展，人们生活水平的提高，当前人们对财产安全和人身安全的重视程度越来越高，此次设计一款智能门禁，主要是为了解决当前大部分用户使用的密码锁在输入密码锁被旁人盗取，或者存在有人多次输入密码从而盗取用户密码，给用户造成财产损失。
随着电子产品智能化和小型化的不断发展，智能门禁已在生活中得到广泛应用，单片机已成为电子产品研发中的首选控制器。由于单片机具有体积小，功耗低，控制精度高，运行可靠的特点，因此在实际生产中得到了广泛的应用。为了更好地促进电子锁在各个领域的应用，此次设计的基于STC89C52单片机控制的电子密码锁。该机器通过使用单片机STC89C52进行编写程序，并使用LCD12864显示监测的信息，并当监测到当前用户的卡为有效卡，且体温正常，继电器控制门锁打开，监测到体温异常进行声光报警并发送短信。此次设计的电子密码锁具有操作监简单、保密性强的优势。

Abstract
Along with the development of the current economic people, people living standard rise, present the importance of property security and personal security is higher and higher, the design of an intelligent entrance guard, mainly to solve the current combination of the majority of users in the input combination lock by others to steal, or there is some input password to steal the user password for many times, to the user caused property losses.
With the continuous development of intelligent and miniaturization of electronic products, intelligent access control has been widely used in life, and single chip microcomputer has become the preferred controller in the research and development of electronic products. Because microcontroller has the characteristics of small size, low power consumption, high control precision and reliable operation, it has been widely used in practical production. In order to better promote the application of electronic lock in various fields, the design of electronic lock based on STC89C52 microcontroller control. The machine uses single chip microcomputer STC89C52 to write programs and LCD12864 to display the monitored information. When the current user’s card is detected to be a valid card and the temperature is normal, the relay controls the door lock to open, and the abnormal temperature is detected to give sound and light alarm and send short messages. The design of electronic password lock has the advantages of simple operation and strong confidentiality.
