| Summary: | 碩士 === 國防大學中正理工學院 === 電子工程研究所 === 94 === Due to the vigorous development of the information and networking technologies, remote monitoring and control (MC) applications have become a part of the digital life of humans. In recent years, the ubiquitous network has been proposed and has become a hot research topic. Thus, mobile MC systems will be the trend of future development of the MC applications. For conforming to such a requirement, this research proposes a mobile MC scheme that integrates new wireless technologies, such as ZigBee and RFID (Radio Frequency Identification). In the proposed scheme, ZigBee is utilized in object positioning, environment sensing, and equipment monitoring and control, while RFIF is applied to identify users and enhance system security. Also, we use neural network to construct the positioning model and apply the Web Services technology to establish the system communication infrastructure. Thus, a mobile MC system based on the proposed scheme can not only provide general MC functions, but also possess various advanced capabilities, such as indoor object positioning, wireless user identification, environment sensing, wireless image transmission, active push of warning messages, and supporting operations using diverse mobile devices. The testing results show that the indoor positioning function achieves a degree of accuracy with an average error of 1.624 m, which can satisfy the indoor positioning demand of a MC system. In addition, the operational times in remote control and active push are 235 ms and 336 ms, respectively, which demonstrates the quickness of the system operations. The research results can be applied in various MC applications for factory and military. They are also a useful reference for constructing new-generation mobile MC systems.
