Optionally, in an embodiment of the present invention, described method further comprises:
Video management main frame in described closed-circuit TV system pushes the real-time video information of equipment accordingly or preserve to large-screen according to described status signal.
Embodiment mono-:
DCS and industrial television link in real time, and industrial television and DCS carry out RS485 communication, take the mode of similar warning, and the operation in DCS and warning are presented on the large-size screen monitors of centralized control room appointment in real time, automatically.For example: when high pressure water pump is operated to (start/stop), when operator clicks the M/A Mode operating block of high pressure water pump, DCS gives closed-circuit TV system by this signal automatically, allows the appointment large-size screen monitors of centralized control room show the picture of high pressure water pump.And for example, when DCS one-level or secondary occur reports to the police, system also allows industrial television display alarm equipment picture automatically, for operations staff provides various information on services.
As shown in Figure 5, be the workflow diagram between industrial process control system and closed-circuit TV system in power plant video monitoring in the present embodiment.
Step 501): DCS and industrial television link in real time, industrial television and DCS carry out RS485 communication, take the mode of similar warning.As shown in Figure 5 a, be industrial process control system operation chart in the present embodiment.On DCS operation screen, click 1# water ring vacuum pump, after click, occur equipment operating end as shown in Figure 5 b.This operating side represents that operating personnel have the possibility of operating equipment.
Step 502): the video information by M/A MODE status word trigger equipment is status signal accordingly.
M/A MODE is operating personnel's man-machine interface operating side, by M/A MODE status word, confirms that operating personnel need to, to this operate, judge that with this this operator has the necessity of checking this equipment real-time video information.
Step 503): according to status signal, DCS is by RS485 output logic, whether this logic need to show for video flowing corresponding to equipment that operating personnel click in man-machine interface on the large-screen of closed-circuit TV system.
In this step, there are two functions: the one, write the mapping relations of all devices and real-time video video camera, the correspondence of assurance equipment and video information; The 2nd, logic is strictly carried out " writing " operation, does not have non-" reading " operation, guarantees the one-way of communication, guarantees being perfectly safe of DCS, prevents Virus entry.
Step 504): by the DCS Three-Part protocol card based on RS485 communication, transmit the digital information in flowchart logic.
Step 505): the signal that closed-circuit TV system sends according to DCS Three-Part protocol card shows corresponding video flowing on large-screen.
Step 506): video management main frame pushes out corresponding video pictures according to information output order.As shown in Figure 5 c, the real-time monitored picture in scene of screen ejection 1# water ring vacuum pump in central station of floating dock.
Step 507): large-screen pushes out corresponding real-time video picture.As shown in Fig. 5 d, it is the real-time monitored picture schematic diagram in scene of 1# water ring vacuum pump in the present embodiment.
To sum up, when DCS operating personnel need start/stop equipment by control system, or while checking the state of certain equipment, operating personnel are by specific operation, DCS produces high level or digital quantity " 1 " signal in control logic, and this signal is delivered to closed-circuit TV system by communication, and closed-circuit TV system receives after this signal, on central station of floating dock large-screen, push out the real time video image of this equipment, for operating personnel, check.In addition, by above-mentioned example, when operating personnel are likely during operating equipment, corresponding real-time monitored picture automatic spring is on large-screen, for operator provides more information for judgement, handled easily personnel grasp facility information comprehensively, confirm status of equipment, such as equipment whether have people's operation, whether exist abnormal etc.
Embodiment 2:
The real-time interlock of gate inhibition and industrial television, industrial television and access control system can provide more service after merging, and at the indoor real-time demonstration of centralized control full factory access control system service chart (being electronic chart), show the state of each controlled door of full factory.When certain fan door is unlocked or closes, system automatic-prompting is informed operations staff, and the industrial television that simultaneously links is recorded a video, captured, be ejected into monitoring large-size screen monitors, facilitate operations staff to identify, and filing storage in entrance guard management main frame, plant area's circumference has people to swarm into chamber, reports to the police.
As shown in Figure 6, be the workflow diagram between access control system and closed-circuit TV system in power plant video monitoring in the present embodiment.
Step 601): each gate current state information of access control system monitoring jurisdiction; As shown in Figure 6 a, be normal gate inhibition's schematic diagram in central station of floating dock in the present embodiment.As we know from the figure, door A, door B and door C are all in closed condition.
Step 602): access control system is directly sent to video management main frame by gate state change message and processes, and actuated camera is captured; Or access control system, directly using gate state change message as triggering signal, video camera corresponding to triggering signal exports to by warning, actuated camera is captured, and feeds back to video management main frame;
Step 603): video management main frame pushes out corresponding real-time video picture according to information output order to large-screen;
Step 604): video management main frame is filed storage by video camera feedack.
As shown in Figure 6 b, the gate inhibition's schematic diagram changing for central station of floating dock gate state in the present embodiment.When there being people to be swiped the card and opened the door or when button opens the door within doors, in gate inhibition figure, show gate C state, for opening, is expressed as black by card reader, as shown in Figure 6 b, meanwhile gate control system can be given supervisory control system by the information of this state variation (unlatching).As shown in Fig. 6 c, be the video figure at the gate of central station of floating dock internal state change in the present embodiment.Supervising device is received after signal, the meeting real-time pictures that the doorway CCTV camera of show gate C gathers on large-screen.
In sum, when there is open mode at the gate of access control system monitoring, by access controller, alarm signal is delivered to the video camera of correspondence with it, or signal to by access control system the corresponding video camera that video management main frame drives with this and opens, video camera is captured.Video management main frame is pushed to the real-time pictures of this video camera on large-screen, and sends to access control system to file storage in the picture of candid photograph.
Finally it should be noted that: above-mentioned only in order to the present invention to be described and unrestricted technical scheme described in the invention; Although this specification has been described in detail to the present invention, but, those skilled in the art still can modify or be equal to replacement the present invention, and all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in claim scope of the present invention.
