【摘要】：随着经济的不断发展,我国城市机动车数量日益增加,汽车的飞速增长与停车位稀缺之间的矛盾日益尖锐,而传统的停车场对停车位的实时状态却并不关注,管理技术较为落后,大大降低了停车场的车位利用率,使得本就稀缺的停车位反倒无车可停,进一步加大车主停车的难度。综上所述,智能化、自动化、高效化的停车管理系统迫在眉睫。而对车位感知方案的研究可以使停车场管理员实时掌握整个停车场的车位状态从而指导车辆泊车,既方便了停车场管理员管理,也节省了车主的时间,是提高停车场智能化管理的一个重要方面,能在 一定程度上解决停车场效率、车位利用率、安全和管理上的智能化需求。 本文通过对比各大主流车位感知方案,选用了基于RFID (Radio Frequency Identification)的微波感知方案,提出了二级协同感知模型和n级协同感知模型,并通过实际工程数据验证了二、三级协同感知模型确实能够明显地降低实际系统成本。最后,提出并验证了一种基于时分复用和双工通信的车位感知RFID信号防碰撞算法,总结出一整套实用的车位感知新方案。 另一方面,本文提出了一套基于协同感知的智能停车管理系统解决方案。方案设计了半自动化的出入场收费管理模式、基于广播式定时增量下发的车位引导体系,实现了基于协同感知模型和信号防碰撞算法的车位感知网关、基于室内WiFi指纹定位的反向寻车子系统、基于SOAP协议的Web Service网关传输中心等。方案集车位感知、车牌识别、出入场收费、车位引导、反向寻车、网管传输、中心管理等七大功能于一体,在实用性考虑的基础上,基本实现了智能停车管理系统高效、智能、自动化等特点。
[Abstract]:With the continuous development of economy, the number of urban motor vehicles is increasing day by day in China, the contradiction between the rapid growth of cars and the scarcity of parking spaces is increasingly acute, but the traditional parking lot does not pay attention to the real-time state of parking spaces. The management technology is relatively backward, which greatly reduces the utilization rate of parking spaces, makes the scarce parking spaces have no parking space, and further increases the difficulty of car owners parking. To sum up, intelligent, automatic, efficient parking management system is imminent. And the research on the parking space perception scheme can make the parking lot administrator grasp the parking space status of the whole parking lot in real time so as to guide the parking of the vehicle, which not only facilitates the management of the parking lot administrator, but also saves the time of the car owner. It is an important aspect to improve the intelligent management of parking lot, which can solve the intelligent demand of parking efficiency, parking space utilization, safety and management to a certain extent. By comparing the main parking space sensing schemes, this paper chooses microwave sensing scheme based on RFID (Radio Frequency Identification), puts forward two-level cooperative sensing model and n-level co-sensing model, and verifies the second, through the actual engineering data. The three-level collaborative perception model can obviously reduce the actual system cost. Finally, an anti-collision algorithm for parking RFID signal based on time division multiplexing and duplex communication is proposed and verified, and a set of practical new parking space sensing schemes are summarized. On the other hand, this paper proposes an intelligent parking management system solution based on collaborative perception. In the scheme, the semi-automatic charge management mode is designed, the parking guidance system based on broadcast timing increment is designed, and the parking space sensing gateway based on the cooperative perception model and signal anti-collision algorithm is realized, which is based on the cooperative perception model and the signal anti-collision algorithm. Reverse vehicle-seeking system based on indoor WiFi fingerprint location, Web Service gateway transmission center based on SOAP protocol and so on. The scheme integrates seven functions, such as parking perception, license plate recognition, entrance fee, parking guidance, reverse searching, network management transmission, central management, and so on. On the basis of practical consideration, intelligent parking management system is basically realized with high efficiency and intelligence. Automation, etc.
