In order to thoroughly implement the spirit of the notice of the Yangtze River Waterway Bureau on further deepening the application of digital channels, and promote digital channels to "use habits, use results and form ecology". On January 27, the Yangtze River Channel Survey Center (hereinafter referred to as the survey center) organized and held a digital channel application analysis meeting, which was attended by members of the leading group of the survey center and heads of departments and units directly under the survey center.
At the meeting, in combination with the work responsibilities of each department (unit), the business department, information department and Comprehensive Affairs Service Center comprehensively summarized the annual work of the survey center and the application of digital navigation based on data and graphical analysis means. Among them, the surveying and mapping information department shows the application results of digital channel from the aspects of Surveying and mapping production, achievement management and instrument qualification management. Through the digital channel system, the water level, tide level and flow information of the task channel are queried and analyzed in combination with historical mapping, so as to guide the arrangement of on-site personnel and ships, so as to make the production task scheduling more scientific and efficient; The asset and equipment (safety) department speaks with data, counts the frequency of monthly safety activities and the prominent problems of safety inspection through the digital channel platform, integrates multiple factors such as task volume and key time periods, predicts safety risks in advance and formulates targeted countermeasures. The network operation center, as the application support and guarantee unit of the whole digital channel, truly reflects the efforts to provide high-quality digital channel services for front-line employees through a large number of detailed user operation and maintenance and updated response data
Through the statistical analysis of ship flow, the average daily activity of ships in the whole Yangtze River is more than 18000, and the data of driving ships is about 10000. Through the analysis of ship berthing behavior, verify the accuracy of geographic information on important infrastructure maps such as anchor areas and ports; Through the collision history data of AIDS to navigation, the mathematical model is used to calculate the collision probability risk in each region... ". in the report, the big data application working group showed that through the information means such as big data and cloud computing, the digital channel information resources are deeply excavated, and the AIS data and AIDS data are used to carry out the analysis of ship flow, ship behavior and collision probability of AIDS to navigation, Provide services for channel operation monitoring and dispatching, rational layout of navigation aids and other businesses, and help make accurate decisions on channel maintenance and management.
Zhu Jianhua pointed out in his concluding speech that the digital channel application demonstration report is closely related to the theme, with novel forms and detailed data, which reflects the achievements made in the application of digital channel system to promote business work. He asked: first, attach great importance to the application of digital channel, emancipate the mind, shoulder the heavy burden bravely, and make good use of digital channel not only, Let the digital channel become an important "helper" for us to do a good job and improve services; Second, compaction responsibility, accelerate the formulation of the digital channel application work plan of the survey center in 2022, strengthen the digital channel application assessment mechanism, establish a regular communication and reporting mechanism, and clarify relevant responsibilities and work requirements; Third, expand the depth and breadth of digital channel application analysis, constantly innovate the methods and methods of analysis, take the problem as the guide, highlight the application of energy efficiency evaluation, use digital channel to find weak links, promote reform and construction with use, constantly optimize the internal management mechanism and improve the level of fine management, The digital channel provides a strong driving force for the high-quality development of Surveying and mapping informatization.
