Brief description
Fig. 1 is monitoring system structural schematic block diagram of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings technical scheme is described in further detail, but protection scope of the present invention is not limited to
Described below.
A kind of railway station building electronic ＆ mechanic machine control system, it includes central monitoring station, key-course, field layer and Internet,
As shown in figure 1, central monitoring station includes monitor workstation, form/maintenance work station, database server, web server, leads to
Telecommunications services device, printer, optical projection system, ups power-supply system and gps alignment system；Key equipment such as monitor workstation, database
Server, communication server etc. can select redundant configuration, to improve system reliability.
Monitor workstation is mainly used in the regular job of operator on duty, including data monitoring and analysis, equipment control, pattern
Control, Energy Saving Control, and printing reports, driving projecting apparatus etc..
Form work station is mainly used in automatically generating, edits various production reports and statistical computation form, and exports preservation
Or drive printer to print.
Maintenance work station be used for SFC support execution parameter tuning, system configuration, network management, management of process,
The tasks such as system maintenance maintenance.
Database server is used for system real time history/data analysis, statistics and calculating, and stores real time data to commercialization
Historical data base, is used for retrieval, statistics, analysis.
Web server provides web services function, and the real time data of bas system and historical data are sent out in the form of a web page
Cloth is gone out, and user just can complete operation monitoring task in far-end by intranet or internet, using browser.
The communication server is mainly used in being communicated between central monitoring station and each controller, subsystem, completes stipulations and turns
Change, the function such as data prediction, data forwarding is it is also possible to data-interface as bas and other automated systems such as fas etc..
The communication server is a kind of logical device, both can be separately provided it is also possible to be replaced by other work stations.
Key-course (also known as substation layer) includes ddc controller, plc controller and intelligent controller, is used for completing live machine
The data acquisition of electric equipment, Stateful Inspection and automatically control.
Substation layer should select optimal monitoring scheme and equipment according to the specific requirement of site environment and controll plant.
(1) general ddc controller is selected for general monitored object, this is most typical usage；
(2) for the system that transformer and distribution station, illuminator etc. are relatively large, comparison is independent, some monitor terminals are needed
(rtu) or digital instrument, then composition automation subsystem can be coupled together these terminals, instrument, so using fieldbus
Again communication network is connected to by communication controler afterwards；
(3) for having configured intelligent monitor, such as Escalator, eps(emergency power system) equipment
Deng then, communication converter only need to be installed, the rs-232/485 interface conversion of watch-dog is Ethernet interface (tcp/ip), then
Access to communication networks；
(4) for the occasion that running environment is more severe, such as major long tunnel, bridge, subway etc., then can select reliability
Higher plc replaces ddc.
Field layer includes the multiple sensors, dynamo-electric for output control field for completing live electromechanical equipment data acquisition
The executing agency of equipment；Each part in central monitoring station is connected by Internet respectively, and field layer passes through to control layer access net

Amount, digital quantity etc.；Receive the order of controller and higher level main website, by switch, the output control such as valve (actuator), adjuster
System；In many cases, scene need configure manual-operating mechanism so as on-site maintenance, maintenance or in emergency circumstances complete operate
Task.
Tbas-2000 generally adopts third generation bas technology, i.e. substation layer equipment such as ddc, plc or other Based Intelligent Control
Device provides Ethernet interface, it then follows tcp/ip agreement, has access to Ethernet, so that system network architecture is more flat
Change, network performance is more excellent.
For big-and-middle-sized station, in order to extend network transmission distance and improve antijamming capability, communication media can select
Optical cable, switch can select optical fiber industry Ethernet switch, and network can also adopt double web frames or loop configuration to carry
High reliability；For super-huge station, the higher area of floor is larger, can adopt comprehensive wiring technology, communication network is by main line
Subsystem, horizontal subsystem, workspace composition, mains system and system horizontal adopt indoor fire safety optical cable, and workspace network
Then adopt twisted-pair feeder or Shielded Twisted Pair.
For automation equipments such as transformer and distribution stations than the subsystem of comparatively dense, field bus technique can be adopted (such as
Lonworks, rs-485) these devices are coupled together one subsystem of composition, then pass through communication controler or gateway device
Connect with backbone network；If necessary, local monitoring system can be arranged in subsystem one-level, it is that operator on duty, attendant carry
For interactive service.
Central monitoring station is the Dispatch and Command Center of electronic ＆ mechanic machine control system, and its function specifically includes that
Basic monitoring function:
