| Summary: | 碩士 === 國立臺北科技大學 === 自動化科技研究所 === 96 === Traditional surveillance systems are designed based on closed-circuit systems. They monitor the environment within the scope of some fixed locations. Due to the line limitation, the information could not be sent to the remote sites. Also, the information can not be shared by multiple systems. In addition, because of space constraints, traditional monitoring systems often require a large amount of wiring. This not only causes difficulties during construction and expansion, it also increases the construction costs. Digital surveillance systems, on the other hand, take advantage of network features, which is available anytime and anywhere. It also provides multiple accessing capabilities of online systems that make the management of historical information much easier. Backing up can be done while the system operators are away from the computer. Combined with a 3G phone or a PDA, users can achieve the remote operations.
This thesis tried to develop a cross-platform framework for surveillance system by collecting sensing data from servers. The information is packed using SOAP which is based on standard XML format. By utilizing the XML format, the proposed system is able to achieve cross-platform functions. Also, since the SOAP is developed on top of HTTP, it avoids a possibility of being blocked by the firewall. The developed framework does not assume any specific platform or language. A heterogeneous environment is used to test the proposed framework. This study also ensures that all XML documents have following the standards and can be read by clients smoothly
