Automation device
Also known as automation system. The process by which a machine or device is operated or controlled automatically without human intervention according to a prescribed program or instruction. Therefore, automation is an important condition and significant sign of modernization of industry, agriculture, national defense and science and technology.
Automation systems are classified as follows
Category A: ?
1, mine Gigabit fiber optic Ethernet ring network system:
Mine automation system data transmission backbone, to facilitate the exchange of data between the various systems, high-speed, efficient and stable.
2. Ground production automation system (coal processing, screening, etc.):
Automation control system for the production process of ground heavy-media coal processing, screening, etc. The system is mature, which can effectively improve the production efficiency and safety of production
3. Mine safety monitoring and control system: ?
By detecting a series of environmental parameters, production parameters, power parameters and other information in the coal mine, it realizes the necessary alarm and control, and provides technical guarantee for safe production decision-making.
4, mine personnel positioning system:
Real-time understanding of the number of underground personnel, activity traces, statistics on the attendance of the personnel down the mine, when an accident occurs, the rescue personnel can use the system to quickly understand the location of the personnel to take appropriate rescue measures to improve the efficiency of emergency rescue work.
5, digital video monitoring system:?
Transmitting the images of important underground production areas to the ground monitoring center through the high-definition digital camera, so that the production scheduler can accurately understand the underground production situation in real time.
?Class B:?
1, ? Underground tape machine centralized control system: ?
To realize that the underground tape conveyor can be controlled both locally and independently as well as through the ground scheduling center for group network control of the main coal flow.
2. ? Underground drainage system: ?
Real-time monitoring of the water level in the underground pump room and automatic starting or stopping of pumps according to the water level to achieve the purpose of controlling the water level in the pump room.
3, underground power supply automation system:?
To realize "five-remote" control of underground power supply equipments and real-time monitoring and protection of short-circuit, overload, grounding, leakage and other system failures of the mine power grid, as well as on-line diagnosis and localization of the failures.
4, amplified telephone system:?
This system is used for communication in the localized area of production and can realize broadcast half-duplex call. If there is an accident or abnormality, the sound and light voice alarm signal can be given through the amplified telephone; it can also realize the sound and light warning prompts before driving.
Category C:?
1. ? Coal distribution and loading system: ?
Automatically control the loading amount of various types of coal through the coal quality detection meter to ensure the stability of coal blending product quality and loading efficiency.?
2. Pressure fan on-line control and measurement system: ?
It can make the operation of pneumatic machinery and equipment such as underground wind picks, wind drills, water pumps, roadheaders and other pneumatic machinery and equipment safe and reliable, reduce the rate of accidents, minimize the time for troubleshooting, and reduce the operating costs for the production of mines, and improve the operating efficiency.
