Along the general direction of information-based drilling, relying on the continuous improvement of information construction and the maturing of engineering automatic warning software, in August 2016, our company was the first pilot unit of Great Wall Drilling to establish a remote technical support center. The remote real-time monitoring of drilling parameters, data entry and analysis of EISS system, engineering simulation calculation and analysis software and other modules were applied to construct a remote technical support system for drilling engineering, which achieved the control objectives of "pre-prediction", "in-process control" and "post-analysis", promoted the continuous improvement of ROP, steadily reduced the accident complexity rate, and promoted the overall speed-up and efficiency improvement of all well teams of the Company. At the same time, combining with my own work practice, the author puts forward optimization and expansion methods for the problems and development direction in the operation of the remote support system, hoping to provide reference and reference for more people in the industry.展开更多

On the basis of a comprehensive and systematic investigation and a scientific analysis of the development status of mustard industry, especially the technical bottlenecks and problems constraining the industrialized production of mustard in south China, the present study proposed spe- cific research ideas, prospects, suggestions and measures accordingly. It was hoped to provide powerful technical support to promote the industrialized, healthy and sus- tainable development of the mustard industry in south China, and be of practical im- plications for the enrichment of people's "vegetable baskets" and the restructuring of the vegetable industry.展开更多

The hardware of conditioning module can be configured flexibly and the programmable test range can be adjusted owing to programmable multiplexer. An FPGA adaptive filter is designed by the calculated filter coefficient vectors with LMS method to solve the problem of parallel test of fighter weapon system in electromagnetic interference environment. The adaptive signal conditioning technology is characterized by high efficiency,precision and integration. Its application makes the test system successful to conduct real-time and parallel test for a weapon system,which is developed based on VXI bus and virtual-instrument technology.展开更多
