基于单片机的高层电梯住宅快递投递系统设计

基于单片机的高层电梯住宅快递投递系统设计(论文13700字)
摘要：随着网上购物的快速发展，快递行业也迅猛发展。但每次快递员面临着高层住宅时，往往会面临着快递被偷的风险给用户上门送快递，同时会占用其大量时间去投递，从而降低投递效率，如果不送还会被客户投诉。因此，本论文旨在设计安装在电梯上部空间的带有电子锁的箱子的快递投递系统，来改善上述问题。利用电梯内部上层空余的空间，在合适的位置加装板子，并安装基于单片机控制的带有电子锁的箱体。单片机的主控芯片采用AT89S52芯片，密码输入采用矩阵键盘及独立键盘，密码显示采用共阴极的八段显示数码管。系统能完成密码输入、正确开锁、动态存取这些功能。系统的软件实现采用功能强大且易于开发的KeilC51环境，且支持ISP下载。该快递投递系统的关键在于用动态密码来开箱取快递，保证快递的安全。

Design of express delivery system for high rise residential buildings based on MCU
Abstract:With the rapid development of online shopping,Express industry is also developing rapidly.When the couriers face high rise residential buildings each time,they will under the risk of losing express parcels which are asked to send to users’ hand.At the same time it will take up a lot of time to deliver,which reduces delivery efficiency.The couriers will receive complaints if they don’t do it.So,the purpose of this paper is to design the express delivery system with the electronic lock in the upper space of the elevator,which can improve the above problems.Using the spare space in the upper part of the elevator, the board is installed in the right position, and a box body with an electronic lock based on MCU.Single chip microcomputer control chip uses AT89S52 chip.The password input uses matrix keyboard and an independent keyboard.The password display uses a total of eight cathode display tube.The system can do the job of password input, the correct lock,dynamic access and so on.The software implementation of the system relies on the powerful KeilC51 environment which is easy to develop projects.And it support ISP download.The key of the express delivery system is to use dynamic password to open the box to take express parcels,which can ensure the safety of express parcels.
