The Event Management System (EMS) is a command platform designed for major emergency response. Its core functions include receiving, assessing, and verifying emergencies, as well as conducting plan-based command and dispatching.

EMS supports multiple integrated interfaces, enabling it to accept emergency reports from diverse sources. It is primarily used by commanders and staff of command departments. As a supplementary tool to the Computer-Aided Dispatch (CAD) system’s police-related functions, EMS realizes dedicated processing capabilities for major police incidents—covering the operational workflow of the receiving, handling, and feedback phases.

There are three sources of major incident-related police tasks in EMS: 1) Upgraded tasks from CAD’s police receiving and handling system; 2) Pre-planned key events created via the EMS Plan module; 3) Manually initiated tasks within EMS. Additionally, EMS integrates with the Geographic Information System (GIS) and Emergency Knowledge Base System.

Leveraging these integrations, EMS analyzes the situation surrounding an emergency, assesses its potential impact, and supports automatic screening of suitable response plans based on the emergency’s location, nature, and characteristics—allowing commanders to conduct command operations in line with established plans. It also enables on-site decision-making and dispatching for dynamic scenarios.

Compared with CAD’s standard police incident workflow, EMS emphasizes team collaboration and cross-departmental coordination. For a single major incident, commanders can create multiple subtasks and assign them to multiple handlers for parallel processing.

For pre-known major security events (e.g., key official visits, sports event security), EMS allows for the targeted creation of event response plans. At the start of the event, the plan details can be shared with designated handlers to ensure coordinated execution.
