10 o'clock in the evening of June 5th, the light fire in the Limited by Share Ltd Laboratory of mountain building friend machinery He Changqing is working on a tense test. Every project handover requires him to lead the team through several sleepless nights. He is mainly responsible for the development of the control system of the high-end concrete mixing plant, and is praised by the industry as R & D craftsman for its toughness and exquisite technology.
He Changqing
He Changqing, the mountain push builders machinery Limited by Share Ltd, is a well-known manufacturer of concrete machinery in China. Previously, the control system technology level of high-end concrete mixing plant has been monopolized by foreign companies, not only high price but also long supply cycle. 4 years ago, He Changqing first came into contact with the control system. After that, it was found that the advantages of the control system were simple operation and powerful function. The shortcomings of the control system were the problem finding and after sale.Amp; mdash.amp; the foreign companies mastering the core technology of mdash were mastering the initiative of price and service. Since then, he has planted a dream in his heart: one day, they must have their own control system.
since then, He Changqing began to study carefully, dozens of foreign materials, tens of thousands of lines of control code, zero basic English foundation, he did not prohibit. Read professional information and translate it from the most basic syllable to word by word. It was with this tenacity that after 3 years, he nibbled down the foreign materials and knew the principles and details of the control system. In February 2016, the company developed a new mixing plant product, which needs to be modified in the original system. Foreign companies make a design change fee of about 200000 yuan. After the news, he took the initiative to undertake the design changes, combined with his own understanding of the control system, through the modification of the PLC program and the adjustment of the host computer program, the successful completion of the task, to save the cost of the company.
in 2017, mountain building friends started the development project of high end mixing control system. He Changqing served as the leader of the project group. After more than 7 months of efforts, the control system was initially formed to meet the operating conditions and enter the final test stage. From that day, he lived in the laboratory, tested 9 big and more than 300 small items in the test outline, modified the design defects, found the program BUG, and optimized the control mode. After two months and many days and nights, the control system was successfully delivered to the customer. Then, he stared at the customer construction site early and late, after 7 days of uninterrupted test, control system running stable, good results, and obtained the high recognition of the user.
this is a dream pursuit of a technician. It is also a true portrayal of an enterprise's independent research and development road. There is not much momentum. Everything is steady and steady. A difficult problem was overcome, and He Changqing rushed to another subject. It is precisely because of the many tireless efforts made by many technicians like him that China has more independent core technologies and is no longer easily controlled by others.
