【摘要】：经济的飞速发展带来汽车保有量的快速上升,停车难已成为市民出行的一大难题。车主为寻找停车位而产生的低速冗余交通量,不仅提高了出行成本,还增大了道路交通压力甚至造成交通阻塞。很多人因找不到车位而将车随意停在路边,影响交通秩序和市容市貌。运用现代技术做好停车服务信息化、智能化工作迫在眉睫。本文在物联网迅猛发展、无线传感网在各行各业得到应用的大背景下,针对以上问题设计了停车服务信息感知与控制系统,旨在使用户能提前查看停车场车位使用情况并根据需要进行预约,最终减少因寻找停车位而产生的冗余交通量,减少车主停车等待时间,提高停车场运行效率,缓解停车难问题。本文阐述了传感器在车位信息感知中的应用,研究了ZigBee无线通信技术,并利用ZigBee协议栈进行了树型拓扑组网实验。在此基础上本文对停车服务信息感知与控制系统进行了整体硬件设计,包括从信息感知与传输,再到信息处理与存储,最后到信息利用与展示。在信息感知方面,利用超声波传感器和ZigBee模块设计了车位检测器,能够实时感知车位占空状态。接着本文在系统硬件设计基础上进行了软件设计与实现,包括车位信息采集系统、停车场上位机软件以及停车服务信息查询及预约平台。车位信息采集系统的关键技术为超声波测距和ZigBee通信。停车场上位机软件面向停车场管理人员,方便其对停车场进行管理。停车服务信息查询及预约平台面向用户,提供车位查询和预约服务。本文最后对整个系统功能进行了模拟测试,测试结果表明系统能实现预期功能,用户能够通过本文设计的停车服务信息感知与控制系统提前查看停车场车位使用情况,并根据自身需求进行预约。这样的系统对解决停车难问题具有实际意义。
[Abstract]:With the rapid development of economy, the number of cars has risen rapidly, and the difficulty of parking has become a big problem for citizens to travel. The low speed redundant traffic produced by vehicle owners to find parking space not only increases the travel cost, but also increases the traffic pressure and even causes traffic jam. Many people park their cars at random because they can't find parking spaces, affecting traffic order and the appearance of the city. The use of modern technology to do a good job of parking service information, intelligent work is imminent. In this paper, with the rapid development of the Internet of things and the application of wireless sensor network in various industries, a parking service information perception and control system is designed for the above problems. The aim is to enable users to view parking spaces in advance and make appointments as needed, so as to reduce the redundant traffic caused by finding parking spaces, reduce the waiting time for car owners to stop, and improve the efficiency of parking lots. Ease the problem of parking. In this paper, the application of sensors in the sensing of parking space information is described, the ZigBee wireless communication technology is studied, and the tree topology networking experiment is carried out by using the ZigBee protocol stack. On this basis, the hardware design of parking service information perception and control system is carried out, including information perception and transmission, information processing and storage, and finally information utilization and display. In the aspect of information perception, the parking space detector is designed by using ultrasonic sensor and ZigBee module, which can detect the duty cycle of parking space in real time. Then this paper designs and implements the software based on the hardware design of the system, including the parking information collection system, parking PC software and parking service information query and reservation platform. The key technologies of parking information acquisition system are ultrasonic ranging and ZigBee communication. The software of the upper computer of parking lot faces the parking lot administrator to facilitate the management of the parking lot. Parking information query and reservation platform for users to provide parking space query and reservation services. Finally, the whole system function is simulated and tested. The test results show that the system can achieve the expected function, and the users can view the parking space in advance through the parking service information perception and control system designed in this paper. And according to their own needs to make an appointment. Such a system is of practical significance to solve the problem of parking difficulties.
