共享单车智能锁的设计
共享单车智能锁的设计(任务书,开题报告,论文11000字)
摘要
本设计叙述了共享单车在我国的发展现状和共享单车智能锁的发展现状，突出了智能锁的重要性，阐述了本设计的研究意义。传统的机械锁会导致单车使用时的种种问题，如固定的密码可能会给一些人留下可趁之机，机械锁可能会被撬开。因此，共享单车必须依附一种安全可靠的智能锁。首先，固定密码必须更换为随机密码，下一个用户才不必担心上个用户记住密码从而可以放心使用，其次，传统的机械锁容易被撬开，共享单车不能真正共享。在密码输入错误三次或锁被强行撬开时，蜂鸣器必须发出警报提醒用户。在交通发达的今天，共享单车成为人们解决“最后一公里”难题的实用工具，真正意义上的从方便用户出发。因此，一款智能锁就成为共享出行的保障。本设计用51单片机结合编程实现，主要功能包括：单片机生成四位随机密码，并通过GPRS模块将随机密码通过短信的形式发送至手机，用户通过手机收到密码后在单车上输入密码，智能锁解锁。在使用结束后，手机上会显示里程及计费情况。电脑上仿真通过proteus实现。这就是共享单车智能锁完整的工作流程。

ABSTRACT
This design describes the status of the development of shared bicycles in China and the status quo of the development of shared bicycle smart locks, highlights the importance of smart locks, and elaborates the significance of this design. Traditional mechanical locks can cause problems when used in bicycles. For example, a fixed password may leave some people with an awkward opportunity. Mechanical locks may be opened. Therefore, shared bicycles must be accompanied by a safe and reliable smart lock. First of all, the fixed password must be replaced with a random password, so that the next user does not have to worry about the last user remembering the password and can use it safely. Secondly, the traditional mechanical lock is easily opened and the shared bicycle cannot be truly shared. When the password is entered incorrectly three times or the lock is forced open, the buzzer must send an alarm to alert the user. Today, with the developed traffic, sharing bicycles has become a practical tool for people to solve the "last kilometer" problem. In the true sense, it is convenient for users. Therefore, a smart lock becomes a guarantee of shared travel. The design is implemented with 51 single-chip microcomputers. The main functions include: the microcontroller generates four random passwords, and sends the random password to the mobile phone via the GPRS module in the form of a short message. After the user receives the password through the mobile phone, the user enters the password on the bicycle. The smart lock Unlock. After the use is over, mileage and billing will be displayed on the phone. Computer simulation is achieved through proteus. This is the complete workflow for sharing a bicycle smart lock.
