Conceptual Design of Wireless Anti-Theft Alarm System Based on Antenna Array and Wave Transmission Model

摘要

With the development of our society, electronic devices, such as laptops, tablets and mobile phones become increasingly widespread. An accompanying problem of this is the increase of theft aimed at these devices. Even though the proper administration and policy plays an important role to mitigate this crime, they still occur ubiquitously. Therefore, for the sake of eliminating this crime, not only the aspects of administration, policy and legislation should be enhanced, but also the corresponding techniques need to be reinforced. In fact, technology plays a dominant role in preventing crimes. In this paper, a conceptual design of an anti-theft alarm system based on antenna array and wave transmission models will be introduced piece by piece. By implementing a series of electronic components embedded into a protecting wireless network, the location of the protected object can be detected in real time. Once a theft occurs, the computation center will instantaneously obtain the data related to this behavior and assess its authorization and then determine to report or ignore it. This alarm system is specifically suitable for use in public places, for example, libraries, cafes, and holiday villages.
