【摘要】：隨著我國民用汽車保有量的逐年持續(xù)增長，以及在黨的十八大召開以后，我國積極推進(jìn)新型城鎮(zhèn)化建設(shè)和國家智慧城市試點(diǎn)的大背景下，傳統(tǒng)停車場及其技術(shù)已經(jīng)不能滿足新形勢下的使用需求。 目前，，傳統(tǒng)停車場的一些不足主要表現(xiàn)在：難以做到對大型或超大型停車場的車位使用狀態(tài)進(jìn)行監(jiān)控；幾乎沒有做到對停車場內(nèi)各種照明設(shè)備的智能控制；改擴(kuò)建基于有線網(wǎng)絡(luò)通信的停車場的成本過高；在大型停車場內(nèi)尋車不夠方便，車牌號(hào)碼和車位代號(hào)互查機(jī)制還不甚完善。為了能夠盡量達(dá)到實(shí)際停車場的使用需求，融入新型城鎮(zhèn)化建設(shè)和智慧城市發(fā)展的總體要求，結(jié)合ZigBee無線網(wǎng)絡(luò)技術(shù)和現(xiàn)代傳感器技術(shù)，對智能停車場的部分關(guān)鍵技術(shù)進(jìn)行了設(shè)計(jì)和研究。 （1）在車牌識(shí)別的研究中，使用MATLAB軟件，對車牌定位、字符分割和字符識(shí)別等主要工作進(jìn)行了仿真研究； （2）在ZigBee無線通信系統(tǒng)的研究中，選用CC2530芯片，設(shè)計(jì)了節(jié)點(diǎn)的硬件電路，研究了Z-Stack協(xié)議棧的工作過程，提出了符合停車場需求的網(wǎng)絡(luò)結(jié)構(gòu)及節(jié)點(diǎn)布置方案，實(shí)現(xiàn)了ZigBee網(wǎng)絡(luò)的組網(wǎng)及通信； （3）在車位檢測的研究中，基于超聲波測距技術(shù)，設(shè)計(jì)了檢測車位當(dāng)前使用狀態(tài)的方法； （4）在智能照明的研究中，基于人體熱釋電紅外技術(shù)，設(shè)計(jì)了下位機(jī)自主判斷和上位機(jī)命令調(diào)控相結(jié)合，對照明設(shè)備進(jìn)行智能管理的方法； （5）在上位機(jī)管理軟件的設(shè)計(jì)中，使用Visual Basic軟件設(shè)計(jì)了管理系統(tǒng)，完成了顯示車位當(dāng)前使用狀態(tài)，以及管理和調(diào)控?zé)艟吡炼鹊裙δ�。并使用Access數(shù)據(jù)庫，實(shí)現(xiàn)了通過車牌號(hào)碼和車位號(hào)碼查詢停車車輛其他相關(guān)信息的功能。 結(jié)合當(dāng)前傳統(tǒng)停車場存在的不足，對智能停車場的部分關(guān)鍵技術(shù)進(jìn)行了設(shè)計(jì)和研究，并通過模擬和實(shí)驗(yàn)驗(yàn)證了技術(shù)方案的可行性。雖然設(shè)計(jì)的停車場功能與實(shí)際的停車場需求還有一定的差距，但進(jìn)行的相關(guān)仿真和實(shí)物研究仍然對智能停車場的實(shí)際建設(shè)有一定的參考價(jià)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 .
