【摘要】:现代社会中,有许多问题一直困扰着人们,例如车辆的失窃以及电子垃圾的泛滥。本文研究一种内置智能手机的方法,不仅无需多余特殊设备,还能够利用废弃智能手机来建立一个廉价有效的车辆防盗系统。当智能手机固定在车辆内部,并且连接上充电设备之后,利用车载的移动智能终端,由于上述终端中含有功能强大的传感器,例如,加速剂,陀螺仪等,便可以发现盗窃事件,模拟出车辆被盗后的行驶路径,向车主或警察局发出车辆失窃信息。针对智能移动终端的传感器系统,本文利用了传感器系统,获取及时数据和多类型,以及对原始数据的分析矫正纠偏。此外,名为驾驶重现的新兴技术手段也被应用在本文所述的系统中。车辆内置的智能手机首先捕捉驾驶者的驾驶行为和相关运动状态,把上述信息发送给车主。发送时,利用车载自组织网络Vehicular Ad Hoc Network, VANET),利用车辆作为节点组建一个网络,上述移动智能终端不仅可以加入这个网络,还可以加强这个网络的功能;或者通过3G/4G网络来传输。车主通过协同定位的位置信息确定被盗车辆的大概位置,再从车辆经过的最后一个路标点的位置开始,寻找到失窃车辆。现有车载定位系统均依赖于全球定位系统(GPS, Global Positioning System),而此定位系统有两大缺点,其一,很容易被识别和无效掉;其二,在进入停车场等室内区域后无法定位。本文所述系统还发现,把十字路口作为路标点,可以获取到十分明显而独特的位置特征,此方法显著提升了现有航位推算方法的性能。在实验中,本文采用了安卓系统智能手机并证明了此方法的有效性。结果表明,驾驶重现技术在追踪被盗车辆的过程中,减少了定位误差和搜寻时间。
[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.
