【摘要】：随着我国民用汽车保有量的逐年持续增长，以及在党的十八大召开以后，我国积极推进新型城镇化建设和国家智慧城市试点的大背景下，传统停车场及其技术已经不能满足新形势下的使用需求。目前，，传统停车场的一些不足主要表现在：难以做到对大型或超大型停车场的车位使用状态进行监控；几乎没有做到对停车场内各种照明设备的智能控制；改扩建基于有线网络通信的停车场的成本过高；在大型停车场内寻车不够方便，车牌号码和车位代号互查机制还不甚完善。为了能够尽量达到实际停车场的使用需求，融入新型城镇化建设和智慧城市发展的总体要求，结合ZigBee无线网络技术和现代传感器技术，对智能停车场的部分关键技术进行了设计和研究。（1）在车牌识别的研究中，使用MATLAB软件，对车牌定位、字符分割和字符识别等主要工作进行了仿真研究；（2）在ZigBee无线通信系统的研究中，选用CC2530芯片，设计了节点的硬件电路，研究了Z-Stack协议栈的工作过程，提出了符合停车场需求的网络结构及节点布置方案，实现了ZigBee网络的组网及通信；（3）在车位检测的研究中，基于超声波测距技术，设计了检测车位当前使用状态的方法；（4）在智能照明的研究中，基于人体热释电红外技术，设计了下位机自主判断和上位机命令调控相结合，对照明设备进行智能管理的方法；（5）在上位机管理软件的设计中，使用Visual Basic软件设计了管理系统，完成了显示车位当前使用状态，以及管理和调控灯具亮度等功能。并使用Access数据库，实现了通过车牌号码和车位号码查询停车车辆其他相关信息的功能。结合当前传统停车场存在的不足，对智能停车场的部分关键技术进行了设计和研究，并通过模拟和实验验证了技术方案的可行性。虽然设计的停车场功能与实际的停车场需求还有一定的差距，但进行的相关仿真和实物研究仍然对智能停车场的实际建设有一定的参考价值。
[Abstract]:With the steady growth of our country ' s civil automobile and the holding of the 18th Party Congress , the traditional parking lot and its technology can ' t meet the demand of use under the new situation . At present , the shortage of traditional parking lots mainly shows that it is difficult to monitor the use state of parking spaces in large or super large parking lots ; almost no intelligent control of various lighting devices in the parking lot is realized ; the cost of the parking lot based on the wired network communication is too high ; and in order to achieve the use requirement of the actual parking lot , the car license number and the parking space code mutual checking mechanism are not perfect . In order to realize the use requirement of the actual parking lot , the key technology of the intelligent parking lot is designed and researched in combination with the ZigBee wireless network technology and the modern sensor technology . ( 1 ) In the research of license plate recognition , the main tasks such as license plate positioning , character segmentation and character recognition are simulated using MATLAB software ; ( 2 ) In the research of ZigBee wireless communication system , CC2530 chip is selected , the hardware circuit of node is designed , the working process of Z - Stack protocol stack is studied , the network structure and node arrangement scheme which accords with the requirements of parking lot are put forward , and the networking and communication of ZigBee network are realized ; ( 3 ) In the research of vehicle position detection , based on the ultrasonic distance measurement technology , the method of detecting the current use state of the vehicle is designed ; ( 4 ) In the research of intelligent lighting , based on pyroelectric infrared technology of human body , the method of intelligent management of the lighting device is designed based on the combination of the automatic judgement of the lower computer and the command and control of the upper computer . ( 5 ) In the design of the upper computer management software , the management system is designed by using Visual Basic , the current usage state of the display parking space is finished , and the brightness of the lamp is managed and regulated . The Access database is used to realize the function of inquiring the other relevant information of the parking vehicle through the license plate number and the parking space number . Combined with the shortage of the traditional parking lot , the key technology of the intelligent parking lot is designed and studied , and the feasibility of the technical scheme is verified through simulation and experiment . Although the design parking function and the actual parking lot demand still have a certain gap , the relevant simulation and physical research still have some reference value to the practical construction of the intelligent parking lot .
