Digital Video Monitoring System
At present, due to away from the ground, complex terrain and bad environment, miners working in shaft coal mines can easily encounter accidents. Using remote video monitoring system, the ground monitoring personnel can have real-time monitoring on the situation underground. The monitoring personnel can not only vividly monitor and record the safety production status of the job site to discover potential safety hazard and take preventative measures, but also provide first-hand images of the accident for the accident analysis. Therefore, remote video monitoring system is an important part of modern mine production safety monitoring system.
The video monitoring system used in some of the coal mines now are early analogy monitoring, which has low performance and stability. The digital video monitoring system we provide adopts security monitoring products with stable performance and uses standard TCP/IP network protocol and H.264 video acquisition and compression system. The picture and sound can be transferred clearly in very low bandwidth, enabling the coal mine enterprise to send real-time picture to the desktop through various network (LAN/WAN/INTERNET/ISDN, etc.). This video monitoring system transfers video signal and control signal by multicast and realizes multipoint-to-multipoint/point-to-multipoint/point-to-point data transmission. It features high image quality, long transmission distance, large video storage capacity and strong confidentiality.
Features
High image quality, high capacity of resisting interference, anti-explosion, anti-electric spark.
Long image transmission distance, transfer by computer network.
Large video storage capacity, easy for searching.
Based on B/S structure, easy for use, can be watched on any computer in the authorized network.
Easy to install; system maintenance and upgrade are simple.
Professional solution, widely used in important ground production placessuch as coal mine surface plant, car passing area in the wagon balance, mine timber field and material, also widely used in shaft production and safety important places such as mining working face, shaft station, head of the conveyor, shaft coal pocket, etc.
Good confidentiality. The video signal of the video monitoring host forms network packets after encryption and compression. It has better confidentiality in remote transmission.
System Configuration
The digital network video monitoring system consists of three parts: monitoring front-end subsystem, image transmission subsystem and central management subsystem. This video monitoring system is a set of 5th generation video monitoring system. It is fully based on the internet and its designing adopts B/S structure. It is currently the latest technology of remote video monitoring system in the industry.
Monitoring front-end subsystem consists of camera system and alarm detector. For the convenience of facility maintenance, windshield wiper and spray bottle could be added to the monitoring front-end to clean the camera remotely.
The networking equipment of the image transmission subsystem will be slightly different according to the real condition of the customer. It basically consists of network video encoder, wireless bridge, fiber optic transceiver, switchboard and router. Network video encoder transforms the images from the scene and the alarm trigger signal taken by monitoring front-end subsystem into IP packet and transfers it to remote client by various networks.
Central management subsystem consists of server management system and video walls or large screen system. The server management system completes the management on remote equipment and client. Video wall and large screen system is composed of network video encoder, video wall or large screen. It receives monitoring images from the internet and output projection to the video wall or large screen after decoding.
