Computer technology is applied in the field of communication and electronic equipment, but it is still in the initial stage in the field of engineering application. With the improvement of construction engineering quality requirements and national construction supervision requirements, building low-carbon, environment-friendly and efficient construction projects has become the benchmark of modern buildings. The birth of BIM technology has promoted the process of information construction in China and played a key role in the construction and management of major projects. The application of BIM technology has become an important means to promote the construction management in the new era of building information development. People have very high requirements and quality for the construction industry. Based on the rapid development of computer technology and the strengthening of engineering management ability, technology has also created conditions for rapid development. At the same time, efficient use of technology can create a more efficient platform for building and resource information and help construction units make decisions. Scientific renovation of buildings can determine the main competitive targets.

According to the statistics of the United Nations Commodity Trade Database, the world consumes more than 50 billion tons of sand and stone resources every year, averaging 18 kilograms per person per day, second only to water resources, and among them, China is the world's largest consumer of sand and gravel, with a total consumption of more than 17.8 billion tons in 2020. The shortage of sand has become a global problem, and some areas in China have also fallen into the embarrassing situation of "no sand available". Moreover, considering the ecological hazard, sand mining has been strictly prohibited in many rivers and lakes in China, and it is an irreversible trend that mechanical sand replaces natural sand. At present, China's industrial equipment manufacturing system is the wisdom of the equipment manufacturing industry of our country's modern major industry and high-end equipment manufacturing enterprise has been dedicated to the development of technological research and innovation is an important technical content, the paper simply introduces some industrial intelligent manufacturing system in the current our country Erdaozhuang sandstone in the system need to involve the use of technology application, including the yard. The paper also introduces in detail from several different aspects the latest industrial intelligent system technology and future industrial development technology of the sandstone system project department of Erdaozhuang abandoned mine treatment and comprehensive utilization project (hereinafter referred to as Erdaozhuang sand stone system) of Qi County in China. Through the updating of the existing computer system software operating system and the continuous innovation of the hardware structure of the mechanical processing device, it has realized the full range of automation and complete unmanned aerial vehicle operation of the whole Erdaozhuang sandstone system.展开更多
