Article 3 of the "Safety Production Law of the People's Republic of China" clearly stipulates: Safe production management, adherence to safety first, and prevention-oriented policy. In 2010, the National Security Supervision Bureau Order No. 168 clearly required the establishment and improvement of safety and hedging “six major systems†in coal mines throughout the country to ensure the safe production of coal mines, and also confirmed the role of monitoring and control systems. As an objective, mature and stable safety supervision method, the video surveillance system plays a significant role in safety supervision and has been widely recognized by the coal industry.
The main problems facing the video surveillance system at this stage:
The application effect is poor - the resolution of the monitoring point image is low, and only the problem of "seeing" can be solved, and the requirement of "seeing clear" cannot be satisfied;
Less security integration - The coal mine video surveillance system and other security guard systems are mostly operated independently, and do not establish a good linkage mechanism. The entire security system appears to be large and fragmented;
Difficulties in networking - most of the video surveillance systems in the coal industry have only implemented intranet networking. Due to the wide variety of field devices, some devices have been unable to provide interface development packages for some reasons when accessing the platform. At the same time, the network conditions of each network are complex. , private network and public network access coexist, only a few areas have achieved a small number of mine access;
It is difficult to operate and maintain a large number of systems. After a part of the system is connected to a network, the huge amount of video surveillance equipment is used. The workload of operation and maintenance is huge and it is difficult to detect. It often causes faults to be handled in a timely manner, which makes the use of video surveillance systems significantly less effective.
Solution The Digital Coal Mine Video Surveillance System solution is mainly applied to the construction and renovation of digital coal mine video surveillance systems at all levels of coal mining enterprises.
Digital Coal Mine Video Surveillance System is a large-scale network monitoring system integrating hardware, software and network. It focuses on the iVMS-8800 platform software of the energy industry, realizes multi-level networking and cross-regional monitoring, and can be used to monitor front-end systems at all levels of monitoring centers. Centralized monitoring, unified management, and escort for safety production.
The Digital Coal Mine Video Surveillance System adopts high-definition, intelligent, Internet of things, and 3G application technologies. Under the guidance of the “Standardization, Integration, and Intelligentization†design principles, it adopts standardized industry products and achieves the following functions:
Multiplex Video Surveillance: Support high-definition video surveillance, intelligent video surveillance, mobile video surveillance, and comprehensively improve video quality and security levels;
Auxiliary system integration: The integration of subsystems such as video surveillance, environmental monitoring, security alarm, and intelligent control is implemented, and the subsystems are linked according to the preplan;
Three-dimensional supervision mode: Realize vertical supervision at the front end, district, county, and city level. The fixed network uses C/S and B/S methods for access. The mobile network is supervised by handheld management terminals (mobile phones, tablets, etc.);
System operation and maintenance management: IT infrastructure management, video quality diagnosis, bandwidth optimization and control, asset management, log management.
Solution Highlights 1) Access and integrate downhole environmental data to realize the management and presentation of coal mine panoramic data, and perform video review on some environmental volume alarms;
2) Deploy a personnel flow statistics system at the entrances and exits of mines to record personnel entering and leaving the mine daily. Once in and out of personnel are found to be inconsistent, inventory, verification, and rescue can be started in time;
3) Realize the docking of coal mine entrance and exit weighbridge system and video supervision system. Weighing data of the weighbridge can be superimposed on the video screen in real time, which can prevent internal personnel from damaging the company's interests and calculate the cost, and can also prevent overload and overweight.
