Intelligent Rail Transit (Ningbo Metro Line 1) Project
Mainly divided into two parts: subway video surveillance system+subway power distribution monitoring system application
1. Subway video surveillance system
1.1 Subway Video Surveillance System - Project Overview
The subway video surveillance system is divided into two parts: operational video surveillance and public security video surveillance. The dispatcher responsible for operation monitoring needs to monitor the station, passenger flow inside the train, and the boarding and alighting of passengers in real time to ensure safe, efficient, and timely operation; In case of emergency situations (such as fires, counter-terrorism, natural disasters, etc.), provide real-time images of the incident site to relevant personnel for easy command of on-site rescue and passenger evacuation；
2. Application of subway power distribution monitoring system
2.1 Project Overview
As a large-scale infrastructure for urban construction, the subway is not only the backbone system for urban public transportation, but also a support system for urban construction and
land development The modernization of subway has become one of the important symbols of urban transportation modernization
The subway station power backup monitoring system is divided into three levels: central level, station level, and local level, which monitor the station power and manage the system
at the central and station levels The station power monitoring system comprehensively and effectively automates the monitoring and management of power equipment at all stations
along the entire line, ensuring that the equipment is in an efficient, energy-saving, and reliable operating state, and creating a comfortable underground environment; And it can better
coordinate the operation of station equipment in emergency situations, fully play the role of various power equipment, and ensure the safe and normal operation of the entire line
The central level power monitoring system consists of a central level circular local area network, which includes primary and backup monitoring hosts, primary and backup servers,
archive management computers, network switches (communication conversion interfaces), printers, printer servers, large screen display systems, and UPS equipment
The station level monitoring system consists of programmable logic controllers (PLCs) set up in the station environmental control, electrical control room, and station control room
(SCR) to collect status signals of on-site equipment, which are transmitted to the station level server and monitoring workstation through network communication lines. The station
monitoring personnel then issue control instructions through the workstation, which are transmitted to the on-site equipment by the PLC for completion
