120 Medical Emergency Command & Dispatch System

1 Requirements Analysis
The 120 Emergency Medical Rescue Command Center is the central nervous system of the regional medical emergency system, serving as the sole medical emergency dispatch agency providing pre-hospital emergency services to the region. It centrally receives 120 emergency calls in the area and, based on information provided by callers, uses GIS electronic maps, GPS satellite positioning, and vehicle-mounted systems as reference, rapidly formulates emergency response plans through a computer-aided decision-making system, designates dispatching units and destination hospitals, and utilizes network technology and computer wide-area communication networks to promptly issue dispatch commands to the corresponding units, notifying relevant emergency stations and hospitals to make all preparations for receiving and treating patients, thereby providing an efficient, rapid, effective, and systematic 120 emergency command & dispatch system.

• One-click completion of agent off-seat/on-seat/shift handover operations;
• Simultaneous communication with sub-stations and onboard personnel;
• Equipped with expert knowledge base support and major disaster/accident reporting;
• Real-time display of emergency task status and time nodes for various statuses (answer time, dispatch time, departure time, arrival at scene time, patient boarding time, hospital arrival time, return to station time, etc.), with statistical reports for various response times.
  3) Data Management Subsystem
  Supports querying, modifying, and maintaining basic data in the 120 command & dispatch database; can compile statistics on various emergency data, including calls, answering, dispatch, and vehicle assignment, generating daily, weekly, monthly, and annual reports. Data can be exported to EXCEL spreadsheets.
  4) Electronic Map Application Subsystem
  Displays terrain, landforms, buildings, roads, and other information in multiple formats, with view control and layer control capabilities. Features basic map operations including zoom in, zoom out, and pan; includes a vehicle monitoring module that tracks the current location and status of vehicles equipped with GPS onboard terminals and replays historical trajectories; includes an answering assistance module: emergency call location, emergency resource distribution display, duplicate alerts, click-to-dispatch functions; includes an image monitoring module: direct click on the GIS interface to display real-time video from monitoring points.
  5) Digital Recording Subsystem
• Recording module: simultaneous recording of wired and wireless voice, supporting up to 32 ports per system, with 100 hours of recording data storable per 1GB of hard disk capacity;
• Recording playback module: playback available on the recording console, as well as on answering consoles and command consoles;
