Collaborative emergency management mode provides a new idea for further reducing system safety risk in the chemicalpark. Inthispaper,thecloudcomputingandthe expertsystem were used forthe frameworkdesign of the emergency management information system to enhance emergency response capability of collaborative emergencymanagementmechanisms. The use of middleware integrated with multi-source data achieved the unified datamanipulationinterface. Intelligentdeliveryof information system was provided. Using agent-middleware technology to build decision layer could make massive data analysis, data mining and decision from the “cloud computing” platform access for every user. It can provide the necessary theoretical and technical support for enterprises in the chemical park, to give full play to the collaborativeemergencymanagementcapability
