【摘要】：現(xiàn)代社會(huì)中,有許多問題一直困擾著人們,例如車輛的失竊以及電子垃圾的泛濫。本文研究一種內(nèi)置智能手機(jī)的方法,不僅無需多余特殊設(shè)備,還能夠利用廢棄智能手機(jī)來建立一個(gè)廉價(jià)有效的車輛防盜系統(tǒng)。當(dāng)智能手機(jī)固定在車輛內(nèi)部,并且連接上充電設(shè)備之后,利用車載的移動(dòng)智能終端,由于上述終端中含有功能強(qiáng)大的傳感器,例如,加速劑,陀螺儀等,便可以發(fā)現(xiàn)盜竊事件,模擬出車輛被盜后的行駛路徑,向車主或警察局發(fā)出車輛失竊信息。針對(duì)智能移動(dòng)終端的傳感器系統(tǒng),本文利用了傳感器系統(tǒng),獲取及時(shí)數(shù)據(jù)和多類型,以及對(duì)原始數(shù)據(jù)的分析矯正糾偏。此外,名為駕駛重現(xiàn)的新興技術(shù)手段也被應(yīng)用在本文所述的系統(tǒng)中。車輛內(nèi)置的智能手機(jī)首先捕捉駕駛者的駕駛行為和相關(guān)運(yùn)動(dòng)狀態(tài),把上述信息發(fā)送給車主。發(fā)送時(shí),利用車載自組織網(wǎng)絡(luò)Vehicular Ad Hoc Network, VANET),利用車輛作為節(jié)點(diǎn)組建一個(gè)網(wǎng)絡(luò),上述移動(dòng)智能終端不僅可以加入這個(gè)網(wǎng)絡(luò),還可以加強(qiáng)這個(gè)網(wǎng)絡(luò)的功能；或者通過3G/4G網(wǎng)絡(luò)來傳輸。車主通過協(xié)同定位的位置信息確定被盜車輛的大概位置,再從車輛經(jīng)過的最后一個(gè)路標(biāo)點(diǎn)的位置開始,尋找到失竊車輛�，F(xiàn)有車載定位系統(tǒng)均依賴于全球定位系統(tǒng)(GPS, Global Positioning System),而此定位系統(tǒng)有兩大缺點(diǎn),其一,很容易被識(shí)別和無效掉；其二,在進(jìn)入停車場等室內(nèi)區(qū)域后無法定位。本文所述系統(tǒng)還發(fā)現(xiàn),把十字路口作為路標(biāo)點(diǎn),可以獲取到十分明顯而獨(dú)特的位置特征,此方法顯著提升了現(xiàn)有航位推算方法的性能。在實(shí)驗(yàn)中,本文采用了安卓系統(tǒng)智能手機(jī)并證明了此方法的有效性。結(jié)果表明,駕駛重現(xiàn)技術(shù)在追蹤被盜車輛的過程中,減少了定位誤差和搜尋時(shí)間。
[Abstract]:In modern society, there are many problems, such as the theft of vehicles and the proliferation of electronic waste. In this paper, a method of built-in smart phone is studied. It not only needs no extra special equipment, but also can build a cheap and effective vehicle anti-theft system by using abandoned smart phone. When the smartphone is fixed inside the vehicle and connected to the charging device, the theft can be detected by using the mobile intelligent terminal on the vehicle, because the terminal contains powerful sensors, such as accelerators, gyroscopes, etc. Simulate the stolen vehicle path and send the stolen information to the vehicle owner or police station. For the sensor system of intelligent mobile terminal, this paper uses the sensor system to obtain timely data and multiple types, as well as the analysis and correction of the original data. In addition, an emerging technology called driving reproduction is also used in the system described in this paper. The built-in smartphone first captures the driver's driving behavior and related movements and sends the information to the owner. When sending, the mobile intelligent terminal can not only join the network, but also strengthen the function of the network, or transmit through the 3G/4G network by using the vehicle as the node and the vehicle as the node to form a network. The vehicle owner determines the position of the stolen vehicle through the location information of co-location, and then starts with the location of the last road sign point through which the vehicle passes, and finds the stolen vehicle. The existing vehicle positioning systems all rely on GPS and Global Positioning system, but this positioning system has two major disadvantages: one is easy to be identified and invalid, and the other is unable to locate after entering the parking lot and other indoor areas. It is also found that the crossroads can be used as signposts to obtain very obvious and unique location features, and this method improves the performance of the existing methods of reckoning significantly. In the experiment, we use Android smartphone and prove the effectiveness of this method. The results show that the location error and search time are reduced in the process of tracking stolen vehicles.
