摘 要传感设备按约定的协议，把任何物品与互联网相连接，进行信息交换和通信，以实现智能化识别、定位、跟踪、监控和管理The automobile guard against theft system design based on the Internet of things Abstract:We developed a car theft deterrent system based on Internet of Things technology by utilizing the superiority of the theory in order to enhance the reliability and reduce the false alarms for the system. First,some investigations in the car theft deterrent domain had been finished both here and abroad and many Car lost modes had been analyzed too.Then the anti-theft structure model Was constructed.The selections of the system’s sensors were introduced by the agreement,they can use anything to exchange information and communicate connected with the internet.It can fulfill the function of identification,fixxing a position,follow,monitoring and administration.thus we could control the system’s reliability in some degree. The developing process of the car theft deterrent system used Internet of Things technology.The power block.sense block,alarm block and CPU block had been designed in detail after the system overall design.Some special applications had been found especially for anti-theft use in the system character test,which had been carried out for the part and the whole product inspection. The test resuks show that the Car theft deterrent system based on Internet of Things can provide more precise alarms,and also possesses some environmental protection performance.The prototype achieved the design objective,and established a new design direction for the development of the Car anti-theft system.
