1. Background Analysis
With the continuous advancement of science and technology, video surveillance technology has been widely used in various fields, including the coal mining industry. The smart coal mine solution can realize real-time monitoring and management of the coal mine production process by introducing a video monitoring system, and improve mine safety and production efficiency. In order to solve the problems that the underground operation is far away from the ground, the underground situation is complex, there are many uncertain factors in the terrain and operating environment, and the accident rate is high, many coal mining enterprises have installed underground industrial video systems, in order to effectively eliminate safety accidents caused by uncertain factors Laid the technical foundation.
2. Program introduction
The smart coal mine solution uses the security monitoring video EasyCVR platform to centralize and manage the monitoring video of coal mine underground operations, provide the AI algorithm engine platform and monitor the large screen, provide real-time live viewing of underground operation monitoring, and support video recording, playback, and video storage wait.
Real-time data collection is carried out in key points of the coal mine, such as the main and auxiliary wellheads, air wellheads, vehicle entrances and exits, and dispatching rooms, and the video data is transmitted to the algorithm center for intelligent analysis. Empowered by the AI open platform, real-time monitoring of the operator's entry information, Information such as whether the safety protection equipment is worn, the operating status of transportation equipment, the information of freight vehicles leaving the mine, and the situation of personnel in the dispatching room sleeping and leaving work are reported to the relevant supervisory platform at the higher level in real time, so as to realize dynamic detection of coal mines, instead of being limited to events. video recording.
3. System functions
1. Video surveillance convergence
The video surveillance system can monitor the safety situation of the coal mine in real time. Coal mines are a high-risk industry, and safety issues have always been the focus of mine managers. Through the underground video surveillance system, surveillance cameras can be installed in key areas of coal mines, such as wellheads, roadways, working faces, etc., to monitor workers' operations and mine safety in real time. Once an abnormal situation is found, such as fire, gas leakage, etc., the system will immediately send out an alarm to remind the staff to take corresponding measures to avoid accidents in time.
Security video monitoring/centralized video storage/cloud storage/disk array EasyCVR platform can provide video aggregation management services, and support encoding devices through the Haikang equipment network SDK protocol, Haikang Ehome protocol, Hikvision ISUP5.0 protocol, GB28181 protocol, ONVIF protocol , Dahua equipment network SDK protocol, EZVIZ protocol access platform, realize video preview, video playback, video wall, video event monitoring service capabilities, and in the network environment with insufficient network bandwidth and traffic restrictions, it can be replaced by pictures The video mode provides surveillance services.
2. AI Algorithm Analysis
The traditional coal mine production process often relies on manual inspection and monitoring, which has the problems of waste of human resources and blind monitoring. With the application of artificial intelligence technology, the intelligent management of the coal mining industry has also become a trend. Based on video images, by deploying AI algorithm models, intelligent identification and analysis of coal mine monitoring scenes can be realized, real-time monitoring and early warning of abnormal events, illegal operations, and safety hazards in the process of coal mine safety production.
In the coal mine project, the user put forward a demand, hoping that the video analysis system can support 200 video streams from the streaming media server EasyCVR for AI algorithm analysis. Our AI video intelligent analysis platform can fully meet this demand, and can provide a wealth of AI algorithm models for application in coal mine daily supervision scenarios and various business modules, providing AI algorithm analysis support for coal mine intelligent supervision, and improving risk early warning capabilities.
3. Concurrency requirements
Concurrency requirements of the project: code stream 2M, concurrent 500, encoding formats H.264 and H.265, need 4, 9, 1+7 modes for large-screen playback.
Video surveillance/video centralized storage/cloud storage/video convergence EasyCVR platform supports multi-protocol access and multi-protocol distribution, with high stability, high concurrency, high reliability and other performance characteristics, which can fully meet the concurrent 500 demand of coal mine project sites , and the EasyCVR platform supports H.264, H.265 video encoding formats, supports simultaneous playback of multiple high-definition video streams, supports multi-screen display of video images (1, 4, 9, 16), video timing carousel and other video service capabilities .
4. Server configuration
For multi-device/multi-protocol access and multi-protocol distribution in coal mine scenarios, we recommend using three servers to build a smart coal mine visual safety supervision and risk warning system, two of which are used as access (such as one access to streaming equipment, One is connected to the streaming device), and one is reserved for backup.
Recommended server configuration:
The bit rate of the camera is 2048Kbps, and the read and write speed of the disk is recommended to be 2.5-3 times the bit rate to cope with the temporary bit rate peak and the delay of disk writing, which is 5-6Mbps for a single channel.
4. Program Summary
The application of AI intelligent detection and video capabilities in smart coal mine scenarios can realize real-time monitoring and intelligent management of the coal mine production process. Technical measures such as controllable, preventable, and early risk warnings for globalized security.
The technical solutions provided by TSINGSEE Qingxi Video can deeply integrate the Internet of Things, mobile Internet, cloud computing, big data, artificial intelligence, GIS and other technologies with all aspects of coal safety production, and build a visualized and intelligent integration of enterprise safety production and management Real-time and accurate data collection, highly reliable transmission, resource integration, intelligent analysis and processing, etc. in the coal production process, to meet the needs of multi-dimensional perception, real-time interconnection, collaborative control, intelligent early warning, etc., covering coal mine safety production The whole process, improve management and control capabilities, and help coal enterprises to achieve refined mining, safe production, and intelligent management.
