【摘要】 在目前家用小汽车的购买量日益增长、停车拥挤、车位使用昂贵的背景下,立体车库是解决泊车困难的很好选择。本文设计了升降横移式立体车库控制器,并对立体车库的车位调度算法进行了深入的研究。本文首先介绍了立体车库的开发背景和意义,对立体车库控制器的两个主要组成部分:载车板控制单元和区域控制单元的硬件设计作了详细的阐述。在载车板控制单元中,分别介绍了主从机通信、输入信号检测、状态显示、手动功能以及电源的设计方法。在区域控制单元中,分别介绍了处理单元、输入信号检测、看门狗电路、通信扩展的设计。立体车库的载车板控制单元和区域控制单元之间的通信采用了主从式结构,设计了它们之间的通信协议。以此协议为桥梁,分别给出了载车板控制单元和区域控制单元的软件设计。立体车库的车位调度算法是一个较为复杂的课题,本文首先采用了一般的路径搜索算法。其次,将遗传算法应用于立体车库的最短路径搜索,通过编码、选择、交叉、变异等一系列操作,能够找到问题的最优解或次优解。最后,在MATLAB软件环境下,通过改变遗传算子的参数,对实验的结果进行了分析比较。更多还原

【Abstract】 With the rapid increase of the ability of purchasing cars of people, a trouble problem is coming forth increasingly because of the difficulty and cost of parking. Cubic park is a good way to solve this problem. This paper discusses the design of up-down left-right parking and studies the dispatch algorithm of the position.Firstly, the background and purpose of the cubic park development are introduced in this paper. The hardware design of the loading board controller and the area controller is discussed in details. As to the loading board part, many design methods are introduced, such as master-slave communication, input signal detection, status displaying, manual action, power supply and so on. Also many design methods are put forward when introducing of the area part, such as processing unit, input signal detection, watch dog circuit, extended communication and so on.Secondly, the communication between the loading board part and the area part adopts a master-slave structure, based on which the communication protocol between them is developed. The software design of two parts is also given respectively in the paper.Finally, because the cubic-park dispatch algorithm is a complicated program, on the one hand, a general algorithm of searching path is introduced. On the other hand, the best path of the parking will be sought out via the genetic algorithm (GA) operation of encoding, selection, crossover and mutation. With the MATLAB software, the experiment results are given and GA’s performance is analyzed.更多还原
