基于单片机的超低功耗智能车位锁设计--毕业论文.doc

摘 要 智能低功耗遥控车位锁是一个可以通过低功耗遥控器控制的机械装置，它是用来阻止其他人占用自己的停车位，可以让自己的车随意停放。 现在大部分人采用的车位锁多数为机械式的。每当汽车在停车位停车时，人们都要下车把车位锁的起降杆升起，随后把它锁起来，这样对于我们而言很费事，使用很不方便。尤其是在下雨的时候，人们使用的时候就非常困难了。虽然目前市场上存在一些可低功耗遥控的车位锁，可是它们拥有一个问题，是它们的智能化水平比较低，基本只是起到控制起降杆的升降。 我设计了一个系统，该系统以51单片机为核心，经过软件与硬件的配合，电子与机械部分重新结合，从而选择与之合适的传感器，以此达到车位锁的全方位的可智能控制。采用以Keil-C为核心的开发工具，根据要求，做出对应的设计。 关键词： 车位锁；无线低功耗遥控；单片机；传感器 ABSTRACT Intelligent low power remote control parking lock is a mechanical device that can be controlled by low power remote control. It is used to prevent other people from occupying their own parking spaces and can park their own cars at will. Most of the parking locks used now are mechanical. Whenever the car stops in the parking lot, people want to get off and lift the parking lock lever, and then lock it up, so its very difficult for us, and its inconvenient to use. Especially when it rains, its very difficult for people to use it. Although there are some low power consumption remote control parking locks on the market, they have a problem, which is that their intelligence level is relatively low, basically just to control the take-off and landing rod lifting. I designed a system, this system uses 51 microcontroller as the core, through the cooperation of software and hardware, electronic and mechanical parts to combine, so as to choose the appropriate sensors and, in order to achieve the full range of parking lock intelligent control. Using Keil-C as the core of the development tools, according to the requirements, make the corresponding design.
