Why use coal mine safety monitoring system

1. The role of safety monitoring system in coal mine safety production In coal mine production, the construction of wireless communication systems used in the early days often uses frequency division multiplexing technology, and wireless communication technology to realize the bottom of the well and the ground The connection of the surface, and its communication distance also has certain limits.

2. The coal mine safety monitoring system can achieve management in place and effective monitoring.

3. The coal mine safety monitoring system mainly realizes the monitoring function of the toxic and harmful gas environment such as gas and carbon monoxide under the well. When the gas is limited, the non-intrinsic electrical equipment on the working surface is locked, so that it cannot continue production and prompts workers to evacuate.

Characteristics of coal mine safety monitoring system

DC working grounding, grounding resistance should be determined according to the specific requirements of the computer system; Coal mine safety monitoring system grounding must pay attention to two points: first, signal system and power supply system, high Voltage systems and low-voltage systems should not use common ground loops; Second, the grounding of sensitive circuits should be isolated or shielded respectively to prevent interference from ground flow and electrostatic induction.

Monitoring system: The system is used to monitor various environmental parameters in coal mines in real time, such as temperature, humidity, gas concentration, etc., as well as the production of the mine.Through monitoring data analysis and processing, we can find hidden dangers in time and prevent accidents.

Communication capability: The system must realize information interaction within the mine to facilitate timely alarm and emergency rescue in the event of an incident. Remote control: The system requires remote control of various equipment to ensure the safety of mine personnel.

Which manufacturers are good at mining video surveillance systems?

Shandong Huarui Electric is a good manufacturer of mining video surveillance system in China. The wireless video scheduling system for mining has effectively improved the safety and efficiency of mine production through integrated and automated management means.

Mining Supervisor of Huarui ElectricThe control system has the following advantages: wireless and integration: the wireless video dispatching system for mining adopts wireless communication base stations and wireless cameras to achieve wireless signal coverage of the underground lanes in the coal mine, so that the video dispatching can be transmitted wirelessly.

The better monitoring product brands are: Hikvision, Dahua Co., Ltd., Tiandi Weiye, Panasonic, Infine, Pier and other companies. Hikvision Hikvision was established in 2001. It is a listed company, a well-known brand in the intelligent security industry, and an intelligent Internet of Things solution and big data service provider with video as the core.

Wumu Hengrun Technology Co., Ltd. Reason for listing: Wumu Hengrun has more than 300 employees, and technical personnel account for more than 90%. It is a professional military industry information construction service unit, providing complete information solutions for military industry units.

Which mines must install a coal mine safety monitoring system

According to my coal network, high-gas mines, coal (rock) and gas-protruding mines must be equipped with mine safety monitoring systems.

Article 158 High-gas mines, coal (rock) and gas-protruding mines must be equipped with mine safety monitoring systems. Coal lanes, semi-coal rock lanes and excavation work surfaces of mines that are not equipped with mine safety monitoring systems and rock lanes with gas gushing out must be equipped with methane wind power locking devices or methane power offers and wind power locking devices.

Gas mines must be equipped with coal mine safety monitoring systems. The coal mine safety monitoring system must operate continuously for 24 hours. Access to the coal mine safety monitoring systemAll kinds of sensors should comply with the regulations of AQ6201-2006, and the stability should not be less than 15d. The data and status of the sensor of the coal mine safety monitoring system must be transmitted to the ground host.
