Description
Technical field
The utility model belongs to communication technical field, particularly relates to a kind of Large Railway Tunnel emergency communication system.
Background technology
The main emphasis of railway tunnel Fire prevention design is in the past " preventing " and " disappearing ", when haveing no alternative but be parked in tunnel to accident train, and the research how establishment officer's safe escape does not have system deep and PRACTICE OF DESIGN.When appearance burst emergency episode, cause the inefficacy of various means of communication, when there is no reliable communication mode, actual conditions in tunnel promptly and accurately cannot be reported to floor manager and rescue personnel, micro-judgment can only be leaned on, affect rescue time adversely, even cause unnecessary error and loss.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Large Railway Tunnel emergency communication system, after burst train disaster accident can in time and outside have good information to link up, to adopt an effective measure, reach safe and personnel are evacuated target rapidly, for scene of the accident rescue command provides communication system accurately and effectively, between the scene of the accident and rescue command center at different levels, establish voice, image, data etc. write to each other.
The utility model realizes like this, a kind of Large Railway Tunnel emergency communication system, this system comprises dispatching host machine, phone emergency system and video monitoring system, phone emergency system and video monitoring system are connected with dispatching host machine, and information is passed to is positioned in the dispatching host machine of Surveillance center, described phone emergency system comprises the multiple telephone terminals be arranged in tunnel, telephone terminal is connected on tunnel main frame, tunnel main frame is connected with long-range call center's main frame by data network, is connected in dispatching host machine by call center's main frame.
Further, described video monitoring system comprises the multiple cameras be arranged in tunnel, the image information of described camera collection is connected on video encoder by connecting video optical multiplexer, be connected on Ethernet switch by video encoder, be connected with the monitoring terminal of setting by video area node, described monitoring terminal is connected with dispatching host machine.
Further, tunnel main frame is arranged on station machine room, and audio signal is extended on call center's main frame of tunnel face by the four line audio interface provided by data network, then by the telephone terminal in low frequency protective cable incoming tunnel.
Further, when tunnel main frame is arranged on central machine room in tunnel face or tunnel, directly connect the crisis phone only terminal in tunnel by cable.
The utility model compared with prior art, beneficial effect is: the utility model establishes voice, image, data etc. and writes to each other between the scene of the accident and rescue command center at different levels, write to each other reliably for the scene of the accident and outside establish, provide effective guarantee for formulating, implementing feasible rescue method in time.
Accompanying drawing explanation
Fig. 1 is the system architecture diagram that the utility model embodiment provides;
Fig. 2 is the structured flowchart of the phone emergency system that the utility model embodiment provides;
Fig. 3 is the structured flowchart of the video monitoring system that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1:
See Fig. 1 composition graphs 2 and Fig. 3, a kind of Large Railway Tunnel emergency communication system, this system comprises dispatching host machine, phone emergency system and video monitoring system, phone emergency system and video monitoring system are connected with dispatching host machine, and information is passed to is positioned in the dispatching host machine of Surveillance center, dispatching host machine is connected with dispatching control desk, and multiple scheduling extensions, each scheduling extensions is all positioned at watch bench of station, described phone emergency system comprises the multiple telephone terminals be arranged in tunnel, telephone terminal is connected on tunnel main frame, tunnel main frame is connected with long-range call center's main frame by data network, be connected in dispatching host machine by call center's main frame, call center's main frame is also by connecting crisis phone only control desk, controlled by crisis phone only control desk.
Tunnel main frame is arranged on station machine room, and audio signal is extended in the central host of tunnel face by the four line audio interface provided by data network, then by the telephone terminal in low frequency protective cable incoming tunnel.
Transmission means between tunnel main frame to telephone terminal is cable mode.When tunnel main frame is arranged on station machine room, audio signal extends on call center's main frame of tunnel face by the four line audio interface provided by Access Network, again by the telephone terminal in low frequency protective cable incoming tunnel, telephone terminal is by tunnel host supplying power.This kind of plan of establishment advantage is to share a main process equipment in multiple tunnel, cost-saving, but whether scheme is limited to circuit has Access Network.
See Fig. 3, video monitoring system comprises the multiple cameras 2 be arranged in tunnel, the image information that camera 2 gathers is connected on video encoder 4 by connecting video optical multiplexer 5, be connected on Ethernet switch 1 by video encoder 4, be connected with the monitoring terminal of setting by video area node, described monitoring terminal is connected with dispatching host machine, Ethernet switch being also connected with memory card 3 for being stored by image, being convenient to have access to.
Emergency exit in the gateway, tunnel at two ends, tunnel, sanctuary, Rescue Station rationally arrange video acquisition point.
The video information of video acquisition point is linked into the access node of station or Synthetic Visual System by video optical multiplexer and fiber resource, then by transmission system or data network, vision signal is delivered to scheduling and emergency center; Video optical multiplexer can adopt optical transmitter and receiver and the node type optical transmitter and receiver of point-to-point type.
Embodiment 2:
Be with the difference of embodiment 1, when tunnel main frame is arranged on central machine room in tunnel face or tunnel, directly connect the crisis phone only terminal in tunnel by cable.When tunnel main frame is arranged on central machine room in tunnel face or tunnel, directly connect the telephone terminal in tunnel by cable, tunnel main frame is powered to crisis phone only by cable simultaneously.Tunnel main frame is by transmitting the 2M passage access call center main frame provided.
The obvious advantage of cable mode is: voice signal and power supply signal are fed to telephone terminal by cable by tunnel main frame simultaneously, and the telephone terminal in tunnel does not need independent power supply.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
