The monitoring system software calculates, analyzes, and processes various types of data information on the site, and responds to the on-site transportation situation by means of graphics, digital display, sound, and indicator lights.
Monitoring host: used for data collection, processing, and data forwarding. Provides data interfaces for system management, maintenance, and analysis within and outside the system.
UPS: Ensure the normal power supply of the computer monitoring system, and ensure the normal operation of the station management management equipment when the whole system has power supply problems.
The background monitoring device is set in the control room.
2) Network communication layer
Communication medium: The system mainly adopts shielded twisted pair cable, realizes real-time communication between field device and host computer by RS485 interface and MODBUS communication protocol.
3) Field device layer
The field device layer is a data acquisition terminal, mainly for the AFPM100 series fire equipment power monitoring detector.
