急求通信类关于汽车防盗类英文文献

汽车防盗装置主要有三种类型：即使发动机已经发动也能锁定方向盘使之不能转动的机械装置（如止动杆）；传统的电子报警器；跟踪系统。
止动杆防盗装置目前只能防止偷车兜风的青少年，而无法防职业盗车贼。电子报警器包括扩音警报器、点火断路开关、玻璃撞击声和其他声音传感器、移动传感器和遥控装置。一种利用电脑帮助探查失车下落的新式汽车防盗系统在美国纽约市正式推出。这种名为“老杰克”的汽车防盗系统，关键部件是一种香烟盒大小的发射机应答器，车主可能把它藏在车上任何一个隐蔽处。一旦汽车被偷走，车主报警，警方的电脑探查器发出无线电信号，被偷汽车上的应答器就会有反应，发出求救信号，警方巡逻车专用设备追踪这些信号，不难把失车找到。统计数字显示，装有“老杰克”应答器的失车，寻获率高达98％。美国已在使用的另一追踪系统是“密码报警信号截收系统”。它可以跟踪位于蜂窝电话网所及的任何地方的汽车。该系统装有一台蜂窝电话，当截收系统察觉到有人闯入或盗窃时，电话就会自动拨通监听台，每隔两秒钟报告汽车所处的经纬度。这样，失窃的汽车随时会处于警察的监视之下。这一系统须要警方安装相应的设备，以接受这一系统从失窃的汽车上不断发出的信号。还有一项将遥控技术用于汽车防盗的技术正在试用阶段。车上安装有接收装置，车主携带发射遥控装置，一旦发现汽车被盗，就可通过卫星遥控发射装置，远距离将汽车发动机关掉，使汽车无法开动
Car anti-theft devices, there are three types: even if the engine has been launched can not lock the steering wheel so that rotation of the mechanical devices (such as the stop bar); traditional electronic alarm; tracking system.
Stop under the current anti-theft devices can only drive young people to prevent car theft, but not anti-professional. Electronic alarms including PA alarms, ignition circuit breakers, glass and other sound percussive sound sensors, movement sensors and a remote control device. A computer to help detect the whereabouts of stolen vehicles new motor vehicle anti-theft system in the United States formally launched in New York City. Called Old Jack The car alarm system, key components of a cigarette box-sized transponder, the owner may have it hidden in a car cover. Once the car was stolen, the owners report to the police, the police issued a computer radio signals Profiler, stolen car transponder there is response, sent out distress signal, the police patrol and special equipment to track these signals, it is not difficult to stolen vehicles found. Statistics show that with Old Jack transponder stolen cars, found the rate of up to 98%. The United States has another in the use of tracking system is alarm signal intercept the password system. It can track cellular telephone network at any place within reach of the car. The system is equipped with a cellular phone, when closed systems detect any intrusion or theft, the phone will automatically dial monitor and Taiwan, the report every two seconds in which latitude and longitude car. In this way, the stolen vehicle at any time be in a police surveillance. The system the police have the equipment installed to accept the system of stolen cars from the continuous signals. There will be a car alarm remote control technology for the pilot phase of the technology is. Receiving device installed on board, the owner fired a remote control device to carry if it is found the stolen vehicle can be launched via satellite remote control devices, remote will turn off the car engine, so that car can not start
