Food Safety And Special Equipment Safety Early Warning And Emergency System

With the social development and people's quality of life demands the improvement of society as a whole and the special equipment for the food security a growing concern to ensure that the food and the safety of special equipment more and more important, the party and the government has "two security" to the job with high priority, "two security" is also a job at all levels of health, industry and commerce, food and drug supervision, quality and technology supervision, etc. The focus of the work of government departments.Food and special equipment has a wide range of common characteristics, quantity, and should not be controlled by traditional means and must therefore be carried out by means of information technology security management. Through food safety and special equipment security early warning emergency system, and regulate food safety and special equipment, security monitoring and early warning and response to emergency disposal workflow. Supported through the command center, command structure can be a timely and effective manner to mobilize much-needed resources, the implementation of the control and treatment to reduce the incidents on the health and safety of the people pose a threat to the most effective means of control and optimal allocation of resources, the case with the negative impact of loss of control at a minimum. For maintaining social stability, and reduce the loss of lives and property of the people of far-reaching significance.The research of existing early warning and contingency theory, the design of food safety and special equipment security early warning emergency system model of early warning systems composed of various functional modeling, design emergency response system of the main design platform hardware environment group contingency into.The system design used in the key words included. NET, C #, ASP Programming, OLAP, data mining and other analytical techniques and early warning of the SQL Server2000 database technology.Emergency warning system consists of five subsystems, namely, data acquisition systems, data processing systems, early warning analysis system, emergency command system and information release system. Data acquisition system is responsible for early warning systems for raw data input, the subject of using C #. Net Programming food and special equipment to monitor the entry point Acquisition Detect data input procedures. Original input data into a database of food and special equipment. Original data to obtain the data after the data cleaning and data screening, the screening will receive a data storage into the data warehouse, the system uses SQL Server2000 the Analysis Service of food and special equipment to build data warehouse. Early warning analysis in the food and special equipment data warehouse based on a single indicator of early warning, OLAP and data mining technology for early warning analysis.Single indicators are warning of food and special equipment will be key indicators Detect and food and special equipment to carry out than the standard indicators, in accordance with the actual test results than the standard value of the degree of deviation from set different warning levels, respectively, a corresponding warning signal hierarchy.OLAP approach is to build special equipment for food and analysis of data warehouse model, star model used in this subject, at the same time building a multi-dimensional data cube, star model, truth table and dimension table component. In the model can be based on comprehensive analysis of multiple dimensions. The data cube to slice and drill-down, you can analyze any two-dimensional distribution of the environment indicators and thus the use of moving average of trend fitting analysis, the key technical indicators to predict the future trend of development. Use of data mining trend analysis model, here we use BP neural network methods, type of food and special equipment for the detection of indicators, output and special equipment for the food security status hierarchy.Early warning analysis of early warning signals into the system to deal with emergencies, and emergency command center by the large-screen system, the command dispatch system, video conferencing systems, such as composition, emergency command system is responsible for food and special equipment to dispose of the case command scheduling, according to different levels of case the implementation of different warning contingency plan for disposal of the case.Early warning and information to deal with emergencies through early warning information on the public platform. Information users will be released early warning information into the platform, and users of information reviewed the examination was conducted through the society after the public release. Early warning information release platform for the construction of the use of ASP technology.Finally, the system security mechanism has been designed, respectively, from the physical security, network security, data security and application system security point of view of safety design.
