Many engineering projects independently designed by Luo Dongyuan all use the large-scale and ultra-large-scale logic control circuits and corresponding series of innovative supporting circuits developed by him. This is unprecedented among industrial and mining enterprises in the country. of. Since 1990, Comrade Luo Dongyuan has completed more than 110 large and small innovation projects, two of which have obtained national patents. This year's "Electrical Centralized System for Industrial and Mining Enterprises", "Electronic Switching Track Circuit", "Electrical "Centralized safety DC electronic track circuit" has successively applied for national patents. Five technological progress projects passed the provincial achievement appraisal in August 1996, one of which won the third prize of the State Economic and Trade Commission's Scientific and Technological Achievement Award in November 1999, and one project won the 12th National Science and Technology Achievement Award in September 1999. Silver Medal Award at the Invention Exhibition, one project won the second prize of the Science and Technology Progress Award of the Guangdong Provincial Department of Heavy Industry and Chemical Industry in June 1997, and one project won the third prize of the Shaoguan City Science and Technology Progress Award in June 1998. So far, a number of projects have been successfully implemented and put into use, saving enterprises an investment of 11.85 million yuan. The large-scale electrical centralized project at Shaogang Ironmaking Station, scheduled to be completed by the end of September this year, can save the company another 1.5 million yuan in investment. More importantly, it has greatly improved the transportation efficiency of Shaogang Iron and Steel Co., Ltd., ensured the safety of transportation operations, and provided modern transportation technology guarantee for Shaogang Iron and Steel Co., Ltd.’s main production. After nearly 10 years of hard work, Shaogang Iron and Steel Co., Ltd.’s railway transportation Automatic control technology has leapt from a complete blank to the advanced ranks of industrial and mining enterprises across the country. During the National Metallurgical Enterprise Transportation Science and Technology Work Conference held in Shaogang, experts and colleagues from all over the country visited Comrade Luo Dongyuan's multiple inventions and technological transformation projects and unanimously spoke highly of them. In 1998, experts from the First Survey and Design Institute of the Ministry of Railways and Shougang, Baosteel, Maanshan Iron and Steel, and Wuhan Iron and Steel visited the microcomputer interlocking electrical centralized project of the Shaoguan Iron and Steel Factory Station. They all praised Luo Dongyuan's various pioneering technologies and computers for achieving perfect integration. Combined with this, experts hailed this technology as the "Shaogang Model". Luo Dongyuan's many inventions and major technological transformation projects have aroused strong repercussions in industrial and mining enterprises across the country. In recent years, they have been gradually promoted and applied, providing opportunities for metallurgical railway transportation. made a significant contribution to the cause.
