Analysis And Design Of Monitoring System In Laboratory

Due to the development of network technology and electric technology, monitoring system in laboratory has wide application space. This article discusses analyses and designs the network monitoring system in laboratory based on intellectualized solution of the kind of system.Firstly, the article sets out foundational hardware and function of monitoring system in laboratory, and designs the general system through demand analysis, use case compiling and supplementary specification illumination. Then the collecting data of the system is designed in details. This article focuses on realization research on situation build-up, general designation and foundational function of the system in order to get wider technology application.The system is divided into five lays which includes UI, Application, Domain, Technical, Services, and Foundation with Browser/Server (B/S) mode. Server-side uses Java platform to satisfy the network demand, and bottom driver uses Java I/O Driver (JIOD) to solve the communication problems between Java program of Server and equipment of collecting. Sever frame uses Spring and manages objects with IoC container in order to debase code coupling. Program of client-side uses Flex to satisfy alternation of system interface. Communication Frame of Flex program and Java Server uses Live Cycle Date Services ES (LCDS) in order that Flex program can transfer operation objections of Spring container remotely and can realize synchrotron transmission of collecting data with message service system.This article analyses and designs the modes including transducer, collecting equipment, mission service, alarm-control mechanism, message issue etc. Transducer contains the message of collecting and can update automatically as carrier of collecting data. Equipment objects is an abstract of real equipment which encapsulates the bottom JOID objects and provides easy operation way for super stratum. Equipment mission aims to accomplish equipment collecting and is carried out by mission administer uniformly to avoid serial conflict. Facing the upper and lower limit of system setting and unusual situations, transducer and equipment objects can control and produce alarm message and update data synchronously through releasing messages to client-side.System design expects to build up general equipment service frame, and it can be used to wider scope in need of diverse monitoring system in laboratory.
