Abstract
The utility model discloses a video monitoring system of a shield machine. The system comprises a host, a switch and a display, and is characterized by also comprising power over Ethernet (PoE) cameras, wherein the host employs a network hard-disk video recoder, the switch is a PoE Ethernet switch, and the display is a video graphic array (VGA) display. The video monitoring system of the shielding machine has the advantages of low cost, convenience in wiring, simple operation and maintenance, strong anti-interference capability, good video effect and safe power utilization; and the Ethernet of the monitoring system is relatively independent of a control system of the shield machine, thereby separating digital video signals from industrial control signals, effectively reducing the risk of network obstruction, and improving the safety and reliability of the shield machine.
Description
Technical field
The utility model relates to the tunnel construction machinery equipment technical field, particularly a kind of shield machine video monitoring system.
Background technology
Shield machine is widely used in the urban subway tunnel construction, and the slag notch of the screw machine of shield machine and the slag notch of belt feeder are two very important video surveillance points, can help the situation of slagging tap of shield machine operator judgement shield machine.Shield machine is worked in tunnel, electromagnetic environment is complicated, serious interference, and two video monitor points are inconvenient to connect up apart from the position of host machine distance.
Existing supervisory control system generally adopts two schemes: a kind of is to use industrial computer to be main frame, connect touch display screen, switch and camera, this kind scheme adopts Ethernet to carry out digital data transmission, therefore the video display effect is good, antijamming capability is strong, will carry out the wiring of power supply and two kinds of cables of data due to camera, installation wiring is complicated.Owing to adopting industrial computer and touch display screen, so the attendant is required high, cost is high.Another kind is to adopt traditional DVR as main frame, connect display and camera, this kind scheme adopts the conventional hard video tape recorder, so safeguard simply, with low cost, owing to adopting traditional coaxial cable to carry out the signal transmission, therefore a little less than antijamming capability under the electromagnetic environment of shield machine, the video display effect is poor, also separately needs cloth camera power line, and wiring is complicated.In two kinds of traditional schemes, the degree of protection of power supply junction is low, can't meet shield machine underground construction rugged environment.
The utility model content
The purpose of this utility model is: for the problem of above-mentioned existence, provide a kind of with low cost, wiring is convenient, simple to operate, antijamming capability is strong, video effect good, maintenance is simple, the shield machine video monitoring system of Electrical Safety.
The purpose of this utility model realizes by following technical proposals: a kind of shield machine video monitoring system comprises main frame, switch, display, also comprises the POE camera.
In technique scheme, described main frame Adoption Network DVR.
In technique scheme, described switch adopts the POE Ethernet switch.
In technique scheme, described display adopts the VGA display.
In technique scheme, described main frame connects by ethernet line with switch.
In technique scheme, described switch is connected with the POE camera to support that the ethernet port of POE power supply technique connects with ethernet line.
In technique scheme, described POE camera is connected to the POE ethernet port of switch.
In technique scheme, described main frame is connected the VGA video line and connects with display.
The beneficial effects of the utility model: by the POE camera, with the POE Ethernet switch, by ethernet line, connect use, by the digital data transmission image information, anti-interference is good, and adopt the POE power supply technique by ethernet line, the POE camera to be powered, simplified wiring, avoid other increase power supply, reduced cost.Cancel simultaneously the supply socket of POE camera, adopted Ethernet directly to power, increased the degree of protection of power supply POE camera, improved electrical safety.With network hard disk video recorder as Video processing, the VGA display is as display device, and more traditional industrial computer and the device combination of touch-screen greatly reduce the equipment purchase cost, and meet the Functional Requirements such as real-time display monitoring, video preservation, playback, simple to operate, easy to maintenance.The Ethernet of supervisory control system, with respect to the network independent operating of shield machine control system, separates video signal with the industry control signal, effectively reduce the risk of network blockage, improves the security reliability of shield machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
Embodiment: as shown in Figure 1, a kind of shield machine video monitoring system, comprise the POE camera, POE Ethernet switch, network hard disk video recorder and display.POE (Power Over Ethernet) refers in the situation that existing Ethernet Cat.5 wiring architecture does not make any changes, when being some IP-based terminals (as IP phone machine, wireless local network connecting point AP, web camera etc.) transmission of data signals, kind equipment provides the technology of direct current supply for this reason.POE is also referred to as the electric power system (POL based on local area network (LAN), Power over LAN) or active Ethernet (Active Ethernet), sometimes also be called Power over Ethernet for short, this is the newest standards standard that transmits data and electrical power when utilizing existing standard ethernet transmission cable, and has kept the compatibility with existing Ethernet system and user.The POE camera is used for gathering vision signal, according to actual needs the POE camera is arranged on shield machine the position that needs to carry out video monitoring, for example the slag notch of the slag notch of conveying worm and belt feeder conveyer.POE Ethernet switch and network hard disk video recorder are arranged in the interior electrical control cabinet of operating room.The POE Ethernet switch is the power supply of POE camera, and network hard disk video recorder is as main frame, and stored video data also is converted to analog signal transmission to the VGA display with digital of digital video data.The VGA display is arranged on the operating platform of operating room, in real time the display monitoring picture.
The POE camera is connected on the POE ethernet port of POE Ethernet switch by ethernet line, network hard disk video recorder is connected on the common ethernet port of POE Ethernet switch by ethernet line, and the VGA display is connected on network hard disk video recorder by the VGA video line.
Whole video monitoring system is with respect to shield machine control system independent operating all on hardware and software.The workflow of video monitoring system: video monitoring system powers on after operation, the POE ethernet port of POE Ethernet switch is powered to the POE camera by ethernet line, the POE camera is started working, the POE camera is processed the optical video analog signal, is transferred to the POE Ethernet switch by ethernet line after converting digital signal to.The POE Ethernet switch carries out the data packing according to the IP address of each POE camera with digital of digital video data, by ethernet line, is transferred to network hard disk video recorder.Network hard disk video recorder carries out the file storage according to the digital of digital video data bag by video encoding standard H.264, and becomes analog signal to be transferred to the VGA display by the VGA video line real-time video picture conversion, carries out real-time display monitoring picture.The video file of storing on network hard disk video recorder, can carry out playback to video, to meet the shield machine construction managerial demand.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
