The Xinjiang Navigation and Hydropower Junction Project is a key waterway construction initiative in Jiangxi Province, aiming to establish a smooth, efficient, safe and green modern comprehensive transportation network. Traditional ship lock management systems typically separate the management and control functions, with operators allocated separately, leading to significant waste in human resources and information silos. Targeting the Jiangxi Xinjiang Navigation and Hydropower Junction Project, this research focuses on the development and application of an integrated platform for intelligent ship lock management and control based on the lock monitoring system and intelligent navigation system. The platform aims to resolve the conflict between navigation and surplus water, maximize the utilization of water resources, and achieve the health, safety and performance perception of equipment, as well as predictive analysis and diagnostic evaluation. The ultimate goal is the "intelligent, standardized, precise and convenient" operation and management of the navigation and hydropower junction.

·   Studying the overall architecture of the integrated platform for intelligent ship lock management and control, and establishing a comprehensive and station-wide data center.

·   Studying the interaction of data with different standards through a unified data interface, and achieving automatic control of the lockage process with minimal surplus water and high efficiency.

·   Studying the technology for cross-security partition data interconnection between the lock management system and the monitoring system.

·   Studying the user-friendly human-machine interface of the integrated management and control platform to enhance the monitoring efficiency.

·   Studying a three-dimensional simulation system that integrates hydropower stations and ship locks for improving personnel skills and emergency response capabilities.

·   Having developed an integrated platform for intelligent ship lock management and control, which incorporates data from various systems including control, intelligent navigation, industrial television, information management, operation and maintenance, scheduling, and hydraulic structure monitoring. This platform also enables the connected function of broadcasting and video playing.

·   Having developed the intelligent data interaction technology for the intelligent lock management and control system. This technology enables intelligent lockage scheduling based on constraints such as ship conditions and power plant generation status. It initiates the lockage process through an automated control procedure.

·   Having developed the technology for cross-security partition data interconnection, which collects data from various perception and monitoring systems across the entire station into the integrated platform. This platform forms a comprehensive and station-wide data center encompassing navigation, power, water, and dam conditions. Key elements such as restricted stopping lines, meteorological conditions, status diagnosis, and dam safety data are incorporated as navigational safety constraints and are visually displayed in the monitoring system.

·   Having developed a user-friendly human-machine interface for the integrated management and control platform, incorporating interactive controls such as edit boxes, check boxes, two-dimensional tables, and ECharts charts, seamlessly integrating JavaScript scripting capabilities, thereby enhancing interactive operation functions.

·   Having developed a technologically advanced operation simulation system, established a library of mathematical mechanism models for ship lock equipment simulation, and constructed an underlying model of lock system in a visual, zero-code manner; having established a three-dimensional operation and maintenance platform for ship locks, which is driven by the simulation equipment mathematical model to form a closed-loop process of monitoring, operation and feedback.

The integrated platform for intelligent lock management and control of navigation and hydropower junctions integrates lock scheduling, management, control, and intelligent navigation, all managed and analyzed within a single platform. This integration facilitates better planning of the economic dispatching control of power stations, ensures smooth navigation through the locks, enhances the utilization of water resources in the basin, reduces the workload of operation and maintenance personnel, and improves the efficiency of ship passage. The technology of the integrated platform for intelligent lock management and control of navigation and hydropower junctions has been applied to various locations, including the Antai Navigation and Hydropower Junction, Taihe Navigation and Hydropower Junction, Xingan Navigation and Hydropower Junction, Bazizui Navigation and Hydropower Junction (including the Hushanzui Power Station and Mopiling Power Station), Shuanggang Navigation Junction, and Nanchang Centralized Control Center of JXPG. It has significantly enhanced the overall social image of the navigation and hydropower junctions.
