As the main energy source in China, the large-scale and intensive production of coal will also be the inevitable direction of the national energy strategy, and the automatic control level of coal production equipment has become one of the key technologies in coal mines. Especially, the automation level of key equipment in coal mine production largely determines the overall efficiency and safety level of mine production. The company is committed to the research of coal mine production automation technology, aiming at improving the automation level of key equipment in coal mines, reducing the labor intensity of personnel and improving the safety level of mines. This paper interprets the new concept of "digital mine" from the angle of digital control of main equipment in coal mine. There are 8 mine products independently developed and produced, among which the automatic control system of mine hoist ranks third among domestic peers. In addition to the main control system, our company also has backup protection, mine car operating system, signal system and other hoist supporting products, and all of them have the national coal safety sign license, which is the only production enterprise in Shanxi. The longest belt conveyor system designed and installed by our company has been running in a large coal mine in Jincheng, Shanxi for more than 3 years. This system makes large conveyors safer, more energy-saving and longer. This project has only one strong competitor in China. At present, several other products are not technically equivalent in the same industry. With the improvement of coal mine technology, the continuous implementation of energy conservation and emission reduction policies and the continuous improvement of safety work, especially the increase of resource integration, small and medium-sized coal mines will gradually be replaced by modern large-scale coal mines, and the automatic control of key equipment is an inevitable trend. The above products of our company will become the mainstream products in the market. According to the survey, China has an average annual market of11500 million yuan. In Shanxi province, our company has strong competitiveness. If the capital and market development are done well, there will be a market of 500-700 million yuan every year, with a market share of 5%.
Facing the rapid development of urban construction, the water supply industry adopts modern management science for efficient management, which changes the management from empirical management to scientific management, saves water resources and reduces management costs. Our company specializes in the research, design, development, installation and debugging of automatic control system in waterworks. He has a certain technical level and a lot of practical experience in the automatic control system of the water plant, and is very familiar with the control technology of the water plant. Modern electronic information technology and integrated automation technology are applied to various departments of industrial production, so as to achieve the goals of high quality and high yield of products and low energy consumption of production costs in the production process and enterprise management process, and finally achieve the goal of high efficiency of enterprises. In Shanxi province, Our company has designed and completed: the pressurization frequency conversion system of the first waterworks of Shuozhou Water Supply Company, the wireless remote control system of the water source well, the automatic dispatching system and frequency conversion pressurization system of the second waterworks, the automatic dispatching system and frequency conversion pressurization system of the second waterworks of Jincheng Water Supply Company, the pressurization frequency conversion system of Quwo Water Supply Company, the pressurization frequency conversion system of Qingxu Water Supply Company and the pressurization frequency conversion system of Yangqu Water Supply Company. The automatic control system of Xiangyuan Waterworks, the automatic control systems of the first waterworks and the second waterworks of Lishi Waterworks Company, which have both wired control systems and wireless control systems, are comprehensive in technology.
