A Study Of Petrochemical Enterprise’s Safety Assessment And Safety Emergency System Based On Mobile Terminal

Petrochemical enterprises have been in the face of frequent accidents, serious losses and bad impacts recently. How to develop petrochemical enterprise’s safety evaluation and emergency work more reasonablely has become a study hotspot. Mobile terminal service is being paid more and more attention with the advantages of the convenience of operating, the diversity of function, the comprehensive of data collection and the immediacy of communication, which makes safety evaluation could consider people behavior and emergency scheduling base on more data. So, using mobile terminal to improve the level of safety evaluation and emergency work is a developing trend for Petrochemical enterprises. On this main line, the main study contents and innovative points are as followed:(1) In order to complete the safety evaluation towards the system monitoring ability and fault diagnosability, tank area’s components and units are set as examples to be described and modeled by the method of Petri net. A definition of monitoring ability and fault diagnosability in the form of Petri net is made, and evaluation index and index calculation process for safety evaluation are proposed. Finally, safety evaluation is upgraded with mobile terminal by collecting the information of people behavior and the iterative use of the assessment result.(2) In order to complete the intelligent decision-making towards the Petrochemical enterprise’s safety emergency scheduling, mobile terminal is introduced into the progress of scheduling and a heuristic emergency scheduling algorithm based on mobile terminal is proposed, which could make dynamic optimization for emergency routes, rescue routes and evacuation routes, providing the result which could ensure that the individual journey is as short as possible under the premise of avoiding conflicts between individuals.(3) In order to enhance the automation level towards petrochemical enterprise’s safety evaluation and emergency work, a safety assessment and safety emergency system based on mobile terminal is designed and implemented, which includes safety assessment module, safety management module and safety emergency module. Safety assessment module includes the method of DOW’s index and the method towards the system monitoring ability and fault diagnosability. Safety management module includes the management of materials and the management of works flow. Safety emergency module includes safety emergency plan management, decision-making model management and order sending management.
