Design And Application Of EMMSS In The Remote Distributed Environment Monitoring System

Remote monitoring has long been concerned by the departments ofenvironment, water power and electricity. Nowadays economy is booming,while environmental protection and monitoring has become a thorny issueand attracted a great concern of the national government and the commonpeople. A remote distributed environment monitoring system can improvethe present-day functions, service management of the present-dayenvironment monitoring devices, regulate the production ofpollution-making enterprises and avoid major pollution accidents.Under "The Tenth Five-Year Plan of China"on Key TechnologyResearch Programs, the National Research Center for CRM's(BeijingOffice), Beijing PGeneral Instrument Co., Ltd., and Jilin University(analysis instrument research and development laboratory) work together toperform research into the subject 'Standardized Application Demonstrationfor Scientific Instrument Industrialization.'In this text, the eco-system ofdistributed remote monitors is a sub-project of Standardized ApplicationDemonstration for Scientific Instrument Industrialization. This system isdivided into hardware systems and software systems. EMMSS is one of thesoftware systems.The accomplished targets in this text are as follows:Research the situation of distributed computer applied technology,focus on WML Web Service technology on .NET platform and realize thedistributed structure of EMMSS with XML Web Service.Because of the different parameters in various monitors and differentports to individual pieces of hardware in this system, based on the idea toset up one communication platform to manage many different instruments,this text takes an applicable communication agreement, which includes theagreements of data transformation and data transformation on the Internet,and which is reliable among management software systems, communicationadapters and monitors.The text explains the design with details about the server softwaredeveloped with Web Service, Socket program, and ASP.NET technology.The server takes the responsibilities to communicate with the eco-monitorand process requests from the clients, and is connected to users withwireless net or Internet wire net There are three functional modules, WebCommunication Module, Web Service Module and Web Page Service: theWeb Communication Module is responsible for processing andcommunicating with the adapter; Web Service Module is for data servicerequested by clients, and application requirements from instrument remoteservice; Web Page Service is to recover the data from database and releasethis data on the Internet allowing clients to browse the system through theconnection interface. The text explains the design and implementation methods concerningthe management between client software data and client self, system andclient terminal, as well as instrument remote control module. Datamanagement client provides the client with the management of supervisiondata and the data processing such as search statistics through Web servicevisits database. The client also could format the data form to meet therequirements of self usage and save the edited forms as a module for futureuse. System management client provides the client (mainly for systemadministrator) staff and instrument in the management system. Theinformation about the staff and the monitor are saved in the database server.The client can access the database through Web Service, display it throughclient's view, perform an edit, and send the edited result back to databasethrough Web Service to accomplish data updating. The remote controlmodule as the sub module of remote services allows the client to control theinstrument. Research the software development of CDMA intellect mobile phoneand explain the design and processing methods about the software for themobile client. The client could check the monitor status with mobile clientsoftware developed at the platform of LG8188CDMA and make an order tomonitor for the supervision data and monitor work status. Here are several innovative opinions concerning the current problemsin management software of eco-monitors: First, the current eco-monitor software in the country is a concentratedapplication system of support and modules which joins each piece tightly,so it is difficult to upgrade given the limited range of this system. In thiscontext, the application of XML Web Service will help to realize thedistributed structure of EMMSS and also XML Web Service runs under theInternet transformation agreement that, as a medium between informationcommunications, would communicate beyond the firewalls and process theinformation by overriding the platforms. In addition, this application ofXML Web Service may conveniently be updated and extended. Second, EMMSS supports the Internet and the mobile public net forGPRS / CDMA, which solves the existing problems in the current systemssuch as using simplex communication method which makes it difficult to...
