Digital Instrument Research And Design Of Mobile Surveillance Model

With the advance of computer network and mobile application, the higher demand of meters monitoring system comes along. Mobile monitoring makes it easier for users to get meter value without regional limit, and the intelligent meter monitoring system accords with the requirements of modern industry.This paper studied the architecture and implementation technology of mobile monitoring of digital meters. Research emphases are laid on the following issues:(1)Smart Client Technology is used to establish system architecture. By the partition of function module and definition of interface, the emphases of development are laid on implementations of every module functions.(2)System communication pattern is studied,and Coarse-grained Web Services are designed to transmit data for satisfying the requirement of cross-platform.(3)In accordance with the goals of Web Services design and modularization demand of system, XML Schema is designed for this system model.(4)The method of digital meter value recognition is extended. In this way, mobile monitoring system has self-adaptability and fault tolerant ability.(5) Basic functions of this system are implemented by software programming.The model studied in this paper not only satisfies the requirement of mobile monitoring of digital meters, but also applies to other mobile application system, Therefore, this model has great scientific research value and broad prospect.
