With the rapid development of economy and society, China is facing the challenge that various emergencies are growing. As the country's major transport infrastructure, railway is the main artery of national economy and its safe operation is the people's livelihood event. In this article, emergency of railway line project is the emergency in the course of existing railway operations, damage of the railway roadbed, bridges, tunnels and other works caused by natural disasters, including the impact of rail, communications, signals and other systems running, caused or may cause significant casualties, traffic interruption, loss of property. If unexpected events occur, the damage is very serious. How to use modern computer tools to build a perfect emergency management information system, enhance emergency management capacity of railway administration, prevent and respond the emergency of railway line project timely and effectively, protect the safety of railway traffic, maintain stable social development, has become the common concern of the government, enterprises and the public, become an urgent problem to resolve for railway administration.This paper summarized the status of emergency management at home and abroad, Defined the concept of the railway line project, introduced a number of related theories of emergency management, on the basis of analysis and research on the related concepts of emergency management, proposed to build a decision-based emergency management information system.Secondly, on the basis of describing the composition and duties of the emergency organization, analyzed the emergency information among the subjects of emergency management, divide the information into peacetime and wartime, analyzed of incident information collection elements, proposed to construct an emergency management information system, which is efficient, dynamic, secure, integrated, standards.Then, construct an emergency management information system. According to the principles and framework for building, emergency management information system is composed of organization module, plan modules, resource modules and evaluation modules, the system functions conclude peacetime and wartime, elaborated it from preparedness, prevention, disposal and summary, construct a perfect and practical emergency management information system. Finally, take XA railway administration for example, described the emergency management information system functions and management of XA railway administration, analyzed problems and deficiencies in emergency management of XA railway administration, put forward corresponding countermeasures and suggestions. |
