| Safety in production is of significant responsibility. In order to ensure the safety of workers engaged in the western Geological Survey, China Geological Survey Bureau has developed China Geological Survey Bureau safety insurance system for wild operations in arduous regions of western(for trial implementation) since the establishment in 1999, and has implemented it in Lhasa, Urumchi, Sining, Yushu field workstations and Kashi, Golmud field work sub-stations in Tibet, Sinkiang, Qinghai, and constantly strengthen the construction of emergency rescue and safety insurance. Safety information is the prerequisite and basis for the safety management of workstations, while achieving the construction of safety information in safety management section is an inherent requirement of scientific development in safety management. As the development of computer technology and information technology, establishing Safety Management Information System (SMIS) for wild workstations which based on safety information management has become an inevitable trend.By analyzing the status of the safety management in wild workstations, combining with SMIS and the characters of geological survey in wild regions, making full use of safety knowledge, systematic analyzing methods and network technology, this paper shows the design and development SMIS based on information management in wild workstations which, in which a synthetically scientific and standardized management of safety information in workstations is available.The research of the paper includes three parts:The first part is the research background and significance of this article. In the western part of china, wild geological survey is often operated in mountains, canyons, forests, vast deserts and dangerous moors. Most of these regions are of few people, unconvinced traffic and communication which endanger the working environment. Lhasa, Urumchi, Sining, Yushu wild workstations and Kashi, Golmud sub-workstations has enhanced capabilities of safety and emergency rescue to a certain extent, but there is a certain degree of safety management shortcomings blame to the geological survey system. In order to further enhance the safety management levels and to insure the wild geological survey could be operated smoothly, the construction of safety management platform is proposed by China Geological Survey Bureau.The second part is the theoretical basis for system development. Related concepts, content and characters of management information system is introduced in detail. Management information system is a man-machine system which is constituted by people, computers and other peripheral equipments. It provides users the information supporting enterprises' operation, management and decision-making. As an information management system which is applied in the area of safety, SMIS links safety information from different regions through the network, achieves information sharing and fully utilization, and provides timely, accurate and reliable decision- support for safety managers. The paper also analysis the characters, functions and deficiencies appeared in application. The research of theoretical knowledge has laid a good foundation for design and development of SMIS in wild workstations.According to the range of application of safety management platform and user characteristics, the system uses B/S three-tier structure, which reduces the system's operating costs and improves operating efficiency. The SMIS of workstations is developed by Visual Studio.net 2005 which is the most popular software. Integrating.NET Framework2.0 tool kit (published by Microsoft), the system can achieve the best supporting effects for most users using the Windows operating system. The database is operated by SQL Server 2005, which is not only easy to install and advantageous of the moderate size, but also provides the most convenient and efficient data query under the premise of taking up too much server resourcesThe third part of this paper is design and development of the workstation SMIS. Following requirements of the subject design and development, and circumstances which obtained through the workstation safety management research, the overall scenario of the safety management information system is carried out. Then based on the scenario, Visual Studio.net 2005 and SQL Server 2005 technology are used to achieve the system functions.The overall scenario of the system includes three-tier architecture design, function design, database design and control designThree-tier architecture design means that in the B/S system, the user interface is achieved through the browser, and very few logic objects are implemented in the front port of the computer, the main logic object is still achieved on the server port. Three-tier architecture means denotation layer, function layer and data access layer. The denotation layer is used to display the ASP.NET page; the system's main functions and all the operational logic codes are achieved in the functional layer; data access layer which is used to realize data access function and encapsulate database operations can be called by the business logic layer.Function design is the focus of the entire system design. This part adopts modular design approach which not only reduces the complexity of the software, but also conducive to maintenance, expansion and upgrading of the software. According to analysis required by the system, system users are divided into four categories:system administrator, workstation administrator, the geological survey users and general workstation users. Each user performs different functions distinguished by permissions. System administration manages the information of workstation users and the geological survey users, station-related information and database information. Workstation administrator manages workstation information including project registration information, staff training information, safety inspections information, emergency rescue information, logistics information, decision-support, and information management. The geological survey users can browse the distribution of workstations in the country, and view details of the various workstations. General workstation user can browse the workstation details which he/she works.Well-designed database is the basis for workstation safety management platform; it provides the system a data structure insurance to realize various functions. This article lists main database tables of the system.Workstation SMIS for Web projects defined a user control known as page-turning control, which is used to achieve the Grid View's data binding and the page-turning function.Finally, functions of workstation SMIS are achieved through coding. There are landing interface, system administrator interface, workstation administrator interface, geological survey user interface and general workstation user interface.Workstation SMIS better solves the common problems of safety management in the workstations, which are the loss of safety information, the blocked transport channel, and the delayed feedback information. It is helpful to raise the safety management level in the workstation. |
