【摘要】：随着我国汽车普及率越来越高,大城市中停车难的问题日益突出。停车诱导系统的部署是解决停车难问题的重要途径之一。针对目前地下停车场诱导信息缺失或单一的状况,本文研究并设计的停车诱导系统,以提高停车效率为目标,以改善用户对以往停车过程耗时耗力的体验为落脚点。通过研究停车诱导系统的发展现状以及对北京地区实际停车情况的考察,作者对停车诱导系统的功能需求作出详细分析。按照模块化设计思想,将系统分为出入口控制模块、区域控制模块和车位状态识别模块,在设计并实现诱导系统硬件平台的基础之上,应用总线通讯和图像信号传输技术,并结合嵌入式软件和上位机软件流程设计,实现诱导系统的整体运行。系统硬件部分设计包括出入口控制模块、区域控制模块和车位状态识别模块的原理图设计及实现。出入口控制模块包括以STC15单片机为核心的地感线圈来车检测、道闸控制、语音播报、485通讯、电源电路等。区域控制模块包括以STM32单片机为核心的一主八从的多机通信及CAN总线通讯电路等。车位状态识别模块包括超声波车位检测、红绿灯指示、摄像头图像信号传输电路等。软件设计主要是系统运行流程设计和自拟定通讯协议设计,包括出入口控制模块的嵌入式软件流程设计与实现,出入口上位机软件流程设计。区域控制模块的嵌入式软件流程设计与实现,停车场内上位机软件流程设计。车位状态识别模块嵌入式软件流程设计与实现。需要指出的是,本文设计并实现了一种多路图像信号分时远距离传输的方法,该方法特别适合于大型地下停车场每个车位的图像采集,是停车诱导系统实现精细化管理的有效手段。最后作者对诱导系统各部分软硬件进行原理性验证和实际应用测试,该诱导系统已部署在某大型地下停车场试运行,测试结果给出以秒为单位的停车诱导时效统计数据。结果表明,本文设计的停车诱导系统可实现对大型地下停车场的车辆进行停车诱导,提升停车效率,且系统规模具备灵活的伸缩性。
[Abstract]:With the increasing popularity of cars in China, the problem of parking difficulties in large cities is becoming increasingly prominent. The deployment of parking guidance system is one of the important ways to solve the parking problem. In view of the lack or singleness of guidance information in underground parking lots, this paper studies and designs a parking guidance system, which aims at improving parking efficiency and improving users' experience of time and effort in the past parking process. By studying the current situation of parking guidance system and the actual parking situation in Beijing, the author makes a detailed analysis on the functional requirements of parking guidance system. According to the idea of modular design, the system is divided into three modules: the access control module, the area control module and the parking station status recognition module. Based on the design and implementation of the hardware platform of the induction system, bus communication and image signal transmission technology are applied. Combined with embedded software and upper computer software flow design, the whole operation of the induction system is realized. The hardware design of the system includes the schematic design and implementation of the entrance and exit control module, the area control module and the parking station status recognition module. The entrance and exit control module includes the detection of the ground inductance coil, the gate control, the voice broadcast and 485 communication, the power circuit and so on, which is based on the STC15 single chip computer. The area control module includes multi-computer communication and CAN bus communication circuit with STM32 single chip microcomputer as the core. Parking status recognition module includes ultrasonic parking space detection, traffic light indication, camera image signal transmission circuit and so on. The software design includes the design and implementation of the embedded software flow of the import and exit control module and the design of the software flow of the host computer at the entrance and exit. The design and implementation of the embedded software flow of the area control module and the software flow design of the upper computer in the parking lot. Design and implementation of embedded software flow of parking station status recognition module. It should be pointed out that this paper designs and implements a method of time-sharing and long-distance transmission of multi-channel image signals, which is especially suitable for the image acquisition of every parking space in a large underground parking lot. Parking guidance system is an effective means to achieve fine management. Finally, the author carries on the principle verification and the practical application test to each part of the software and hardware of the induction system. The induction system has been deployed in a large underground parking lot for trial operation. The test results give the statistical data of parking induction time in seconds. The results show that the parking guidance system designed in this paper can guide the parking of large underground parking lots and improve the parking efficiency, and the scale of the system is flexible and flexible.
