Description
Technical field
This patent relates to a kind of video monitoring system, carries out manipulation and the monitoring management of locomotive for parking lot, colliery.
Background technology
In the modernization in the face of coal mine locomotives operational management
,in locomotive operation way, often owing to being subject to the restriction of geographical environment and action, great inconvenience is brought to the wiring installation of cable network, wire transmission.Coal mine locomotives transports building, crossing, Hang Renduo on the way, and transportation range is long, manipulation and scheduling difficulty, such as: 1, because ground electric locomotive driver is unsighted in startup procedure, and normal thing such as generation locomotive and other object scratching etc.; 2, duty management personnel cannot grasp field condition in real time, have impact on to select that cash discharges, the scheduling of stores van and car.In today that the communication technology is greatly developed, traditional approach is backwardness seriously.
Summary of the invention
The object of this invention is to provide a kind of wireless monitoring device for grass parking lot and method for supervising thereof, solve coal mine locomotives and transport building, crossing, Hang Renduo on the way, transportation range is long, manipulation and scheduling difficulty.
For achieving the above object, the technical scheme that this patent adopts is:
A kind of wireless monitoring device for grass parking lot, it is characterized in that, comprise the video acquisition device on console for centralized control, wireless network transmission platform and locomotive, video acquisition device comprise be arranged on locomotive front camera, wireless launcher and locomotive in video storage device, described wireless network transmission platform is connected signal transmission with console for centralized control by cable, the wireless launcher on locomotive and wireless network transmission platform wirelessly transmission video signal.
The described wireless monitoring device for grass parking lot, is characterized in that, described wireless launcher is double frequency 5.8Ghz wireless bridge.
The method of video monitoring is wirelessly carried out in grass parking lot, comprise following step: the parking lot environment be positioned at before the video acquisition camera aligning locomotive in locomotive front is taken, imageing sensor in camera is lined by line scan to the image that camera is taken and is converted to the signal of telecommunication, and the signal of telecommunication scanned is converted to digital coding;
Above-mentioned digital coding is in electrical signal form stored in the data storage disk in locomotive and the graphic display terminal be presented in locomotive;
The digitally coded signal of telecommunication is input to wireless signal transmitting device simultaneously, and wireless signal transmitting device sends the above-mentioned digitally coded signal of telecommunication;
The digitally coded signal of telecommunication is accepted by the wireless network transmission platform being positioned at parking lot, and the digital coding of electrical signal form is converted to the circuit signal of telecommunication by wireless network transmission platform;
The foregoing circuit signal of telecommunication is by cable transmission to console for centralized control, and the circuit signal of telecommunication is converted to reference format video and is shown to display and by this video stored in data disks by the display terminal in console for centralized control.
Native system adopts industrial monitoring technology and mine locomotive to control the information hierarchy combined, and bold is applied to industrial monitoring in locomotive control.By transforming existing locomotive, install wireless bridge and Internet video decoding device additional, the display monitor central monitoring system of driver on locomotive on locomotive can be seen in real time the video pictures in the machine front, need not visit or parking observation in order to sight obstruction turns round and look at body, ensure that security of operation.Realize real-time transmission of video image wirelessly on the locomotive of movement.The radio communication of double frequency 5G relieves the constraint of circuit to watch-dog; by radio wave transmissions vision signal; fast moving objects imaging clearly can be distinguished; solve the circuit dragging questions of terminal equipment; reduce comprehensive wiring; and the full real-time recording memory function of energy, and be convenient to display, storage, retrieval and playback; High definition real time monitoring shows and is easy to taking turn switching, and video is smooth, without card, hinders phenomenon.This system can incorporate full ore deposit video monitoring system, becomes the important component part of Modern coal mines transportation safety manufacturing monitoring system, and new wireless monitor point can join in existing network rapidly by administrative staff, realizes remote wireless monitoring easily.
Specific embodiment
Below discussion is described in more detail to the present invention:
Because locomotive in locomotive transportation is mobile, traditional wired mode can not meet transmission of video.This device is by 8 high-definition network cameras installed, environment before and after operationally absorbing on the way, import network transmission system into after the vision signal collected encoded device coding and deliver to the backward outer transmitting of wireless launcher by feeder line, be simultaneously displayed on the display on locomotive.Trainman, by being arranged on 2 monitor energy on locomotive, Real Time Observation road ahead environment, makes a response rapidly to the hidden danger existed, and can realize the switching of many pictures.Wireless network transmission platform forms the whole locomotive operation route of covering by console for centralized control and access point wireless intrinsic safety base station, 5, stop station.The wireless network transmission platform of wireless intrinsic safety base station and optical transmitter and receiver composition is by video signal transmission console for centralized control, console for centralized control is reduced into the video of standard after receiving signal, the inherent matrix monitor of console for centralized control or DVR process image, and monitor staff can realize viewing, store and management video data.
The high-definition camera of this device adopts model Haikang prestige to look DS-2CD8255F-EIS, infrared adjustable focus waterproof ICR day and night type tube type web camera, and specification is 2,000,000 pixels, and infrared radiation distance is outdoor 20-30 rice.Have progressive scanning picture transducer in high-definition network camera, the image of catching also transmits, and wireless intrinsic safety base station operation, in 5.8GHz full frequency band, is the wireless base station of a kind of high bandwidth, multi-functional, outdoor version carrier class CPE.It operates in the high band of more than 5.8GHz, and transmission speed is the highest has risen to 1Gbps, the content can transmitting about 125MB per second, thus ensure that video flowing clear and smooth.The large frequency range of 5GHz and 2.4GHz two can be covered simultaneously.The little problem of wireless signal coverage can also be improved simultaneously.Monitor adopts Samsung S22B360hwLED monitor, 22 cun, resolution is 1680*1050, has damping, water-proof function.
This device is applicable to the transport of all kinds of grass yard locomotive, and the basic operating mode of system is wireless and cable network the communication mode deposited.Wired is by Industrial Ethernet, and control room monitor staff can be monitored traffic condition in real time by the video wall of Surveillance center, can monitor and record the safety in production at transport scene intuitively and carry out dispatch control.
Be distributed in the video display system of locomotive and Surveillance center, first facilitates trainman to observe front road conditions, expands the sight line of driver, avoids the accident that the place such as to turn round causes because sight line is bad.Second facilitates operator on duty to carry out dispatch control to locomotive.
The machine vehicle radio video system, is conceived to improve motorcycle safety, operability, and provide a class high level, low price, really has the system of actual application value.To sum up analyze visible, native system is new technology, the new invention of the safe operation of grass yard locomotive, improves locomotive operation efficiency and fail safe, is of very high actual application value.
