With the increasing level of automation, information, and technology in the coal industry, efforts are made to enhance the effectiveness of safety production management and improve the advanced and rapid production dispatching and commanding. It is necessary to set up an industrial video surveillance system. Through the monitoring of major production sites, the dispatching commander can directly observe the real-time production conditions at the monitoring site, provide dispatchers with fast, dynamic, convenient and practical information, and provide certain decision support. It is an important measure to improve the production scheduling of coal mines. It is also an important guarantee for improving mine production efficiency.
Mine industrial video surveillance system is mainly composed of cameras, PTZ, PTZ decoder, video server, transmission fiber, fiber optic transceivers, video surveillance server (large screen display system) and so on.
By installing color integrated cameras with pan/tilt heads in the conference room of the mine and the main production sites on the ground and downhole, on the one hand, real-time monitoring of the images in the ore dispatching room; on the other hand, it is connected to the video teleconference system through the local area network. Realize the sharing of video and teleconferencing. At the same time, the large screen display system can also display the graphical files and real-time data monitored in the mine safety monitoring and monitoring system.
Large-screen system consists of DMDTM (digital light processing system) technology-based projection unit (including projection box, DLPTM projector, professional rear projection display screen) multi-screen splicing control system (including multi-screen splicing controller, video matrix switcher) , monitor, system control and related peripheral equipment (cabinet, base, cable, etc.).
Remote monitoring of coal mine safety production with mobile communication technology The large-screen mining safety monitoring system uses mobile GPRS networks and CMNET (various fixed data services of major bearer networks) for networking to send mine safety production information collected by coal mine monitoring terminals to ( Network management control center) The GPRS core network. After the network management center identifies the proprietary coal mine safety monitoring number to the GPRS core network, it connects to the server hosted by the network management system through the CMNET. The monitoring centers at all levels can know the underground mine safety production information of each coal mine by logging into the designated website on the Internet. A mobile SIM card is configured on the communication module of the underground safety monitoring system, and a dynamic IP address distribution method is adopted so as to implement data transmission to the monitoring center and achieve the purpose of remote monitoring.
The large screen of the safety monitoring system is real-time updating the safety production data of mine gas, carbon monoxide, wind speed, temperature, and negative pressure, and assists coal mine safety management personnel at all levels in real-time to master the safety production of coal mines. Regardless of which coal mine has an alarm, the coal mine will promptly feedback back to the system the reason for the exceeding of the gas, whether it is necessary to immediately stop the production and how to eliminate the danger and other relevant information. This information appears at the same time as the relevant regulatory agency, but it will also be sent to the relevant responsible person's mobile phone via SMS, until the danger is lifted. "This security monitoring center is like a live broadcast to the supervision of the coal industry for the supervisory authority, and it has largely ruled out the hidden dangers of coal mine hazardous operations."
Coal mines have all installed safety monitoring systems. “After adopting GPRS monitoring system in coal mines, the safety aspect of coal mines has been better protected. For each miner working underground, it is equipped with a GPRS positioning system. This not only can keep abreast of the progress of miners working downhole, but also After the miners encountered danger, they accurately implemented the rescue and made the monitoring system equal to a pair of 'telescope'.
In the coal industry, the big screen connection system display function realizes full-screen display, high-resolution applications can use the entire wall as a unified logic screen to display high-resolution image screens, and achieve full-screen display and superposition of resolution, such as displaying super high System diagrams, greetings, etc. for resolution.
Multi-channel video signal display supports full-standard video input signals, video surveillance information, video cameras, video recorders, video players, color physical projectors and other video signal sources can access universal multi-screen processor, the signal after the general screen processing In the form of a window, zoom in, zoom out, and move across screens anywhere on the projection display wall.
The network signal display is connected through the network to make the signal display more flexible and convenient. The computer image on the network can be quickly displayed at any position and any ratio on the large screen; the number of various computer workstations is not limited, and the future expansion will only need to be displayed on the wall. The computer can be connected to the network.
RGB, video signal through display zoom through display. The display unit equipped with this image processing card supports full-destructive display of high-definition video signals in various formats such as 1080p, 1080i, and 720p, and can directly input various high-definition video such as HDTV, EVD, HD-DVD, and HD video recorders. Video signal. In the Ã2 and 2ÃN modes (ie, the Visionlink super signal processing board that is configured via the display unit and passed through by the 2Ã), multi-channel RGB and video signals can be displayed in a single-screen mode or on the entire screen in the full-screen range.
Multi-signal mixed display Universal multi-screen processor With multi-screen display for super-high-resolution splicing computer network graphics signals, video signals and RGB signals, and superimposed display of different types of signals, any one of the signal windows can be arbitrary Zoom out, zoom in, cross screen, or full screen.
