【摘要】：經(jīng)濟(jì)的飛速發(fā)展帶來汽車保有量的快速上升,停車難已成為市民出行的一大難題。車主為尋找停車位而產(chǎn)生的低速冗余交通量,不僅提高了出行成本,還增大了道路交通壓力甚至造成交通阻塞。很多人因找不到車位而將車隨意停在路邊,影響交通秩序和市容市貌。運(yùn)用現(xiàn)代技術(shù)做好停車服務(wù)信息化、智能化工作迫在眉睫。本文在物聯(lián)網(wǎng)迅猛發(fā)展、無線傳感網(wǎng)在各行各業(yè)得到應(yīng)用的大背景下,針對(duì)以上問題設(shè)計(jì)了停車服務(wù)信息感知與控制系統(tǒng),旨在使用戶能提前查看停車場(chǎng)車位使用情況并根據(jù)需要進(jìn)行預(yù)約,最終減少因?qū)ふ彝＼囄欢a(chǎn)生的冗余交通量,減少車主停車等待時(shí)間,提高停車場(chǎng)運(yùn)行效率,緩解停車難問題。本文闡述了傳感器在車位信息感知中的應(yīng)用,研究了ZigBee無線通信技術(shù),并利用ZigBee協(xié)議棧進(jìn)行了樹型拓?fù)浣M網(wǎng)實(shí)驗(yàn)。在此基礎(chǔ)上本文對(duì)停車服務(wù)信息感知與控制系統(tǒng)進(jìn)行了整體硬件設(shè)計(jì),包括從信息感知與傳輸,再到信息處理與存儲(chǔ),最后到信息利用與展示。在信息感知方面,利用超聲波傳感器和ZigBee模塊設(shè)計(jì)了車位檢測(cè)器,能夠?qū)崟r(shí)感知車位占空狀態(tài)。接著本文在系統(tǒng)硬件設(shè)計(jì)基礎(chǔ)上進(jìn)行了軟件設(shè)計(jì)與實(shí)現(xiàn),包括車位信息采集系統(tǒng)、停車場(chǎng)上位機(jī)軟件以及停車服務(wù)信息查詢及預(yù)約平臺(tái)。車位信息采集系統(tǒng)的關(guān)鍵技術(shù)為超聲波測(cè)距和ZigBee通信。停車場(chǎng)上位機(jī)軟件面向停車場(chǎng)管理人員,方便其對(duì)停車場(chǎng)進(jìn)行管理。停車服務(wù)信息查詢及預(yù)約平臺(tái)面向用戶,提供車位查詢和預(yù)約服務(wù)。本文最后對(duì)整個(gè)系統(tǒng)功能進(jìn)行了模擬測(cè)試,測(cè)試結(jié)果表明系統(tǒng)能實(shí)現(xiàn)預(yù)期功能,用戶能夠通過本文設(shè)計(jì)的停車服務(wù)信息感知與控制系統(tǒng)提前查看停車場(chǎng)車位使用情況,并根據(jù)自身需求進(jìn)行預(yù)約。這樣的系統(tǒng)對(duì)解決停車難問題具有實(shí)際意義。
[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.
