Nanjing Waterway Operation Monitoring Beacon Alarm and Video Surveillance Achieve Second-Level Linkage
The navigation mark shifted, and the alarm information was just triggered; the real-time monitoring screen for the corresponding point was instantly pushed to the duty screen—taking only a few seconds from alarm trigger to screen display. Recently, the Changjiang Nanjing Waterway Bureau's "Waterway GO+ Video Monitoring Smart Linkage" system completed version updates and officially entered trial operation, marking a new stage of waterway operation monitoring along the lower reaches of the Yangtze River, transitioning from "manual individual checks" to "second-level linkage verification."System Connection Breaks Down the “Data Islands”For a long time, the navigation mark alarm system and video monitoring system in the jurisdiction of the Changjiang Nanjing Waterway Bureau have operated independently. When duty personnel received an abnormal navigation mark alarm, they had to manually log into another system, search and retrieve the corresponding monitoring screen one by one, which often took several minutes to confirm the danger. During adverse weather such as night time or fog, on-site boat inspections were restricted, further prolonging the danger verification chain."The alarm is the alarm, but viewing the screen requires starting all over again—the two systems are like separated by a wall," said a relevant person in charge of the bureau’s command center. "The response delays caused by data barriers are an unavoidable bottleneck in waterway emergency handling." Targeting this pain point, the bureau began connecting the Waterway GO module with the Hikvision video monitoring system. They matched navigation mark location information with related monitoring points, achieving precise association. Alarm signals now automatically trigger the corresponding cameras, instantly pushing real-time footage to the command terminal.Point Matching Locks on the “Optimal Perspective”Linkage is not merely simple data integration. Navigation marks along the Nanjing section of the Yangtze River are widely distributed with numerous monitoring points, and there are often multiple cameras around the same navigation mark, differing in distance, viewing angle, and clarity of footage. To ensure that the linkage delivers "accurate and clear" visuals, the bureau organized efforts to conduct comprehensive coverage surveys of all navigation marks and monitoring points within its jurisdiction. They systematically sorted and matched corresponding relationships, considering indicators such as point distance, image resolution, and monitoring coverage range to select the optimal monitoring points and preset perspectives for 410 navigation marks. They then completed system input and debugging for each.Linkage Enhances Efficiency and Strengthens the “Smart Defense Line”In October, the linkage function officially began trial operation. Currently, the system runs smoothly, and its effectiveness in control is obvious. The most noticeable change is the responsiveness. Previously, duty personnel had to go through multiple manual steps from receiving an alarm to confirming the situation on-site. Now, the alarm information pops up accompanied by real-time footage, significantly reducing the verification process and securing a valuable time window for subsequent handling.Another area of improved efficiency is inspection coverage. During autumn and winter in the lower reaches of the Yangtze River, frequent strong winds and fog often limit the departure of vessels, creating blind spots in traditional manual inspections. With the linkage system now online, the frequency and coverage of electronic inspections have significantly increased, enabling round-the-clock, uninterrupted dynamic monitoring of waterway facilities and effectively addressing supervision gaps during adverse weather.This linkage upgrade is a reflection of the Changjiang Nanjing Waterway Bureau's efforts to advance smart waterway construction. With the impact of the global El Niño phenomenon, extreme weather events are increasingly frequent in the Yangtze River Basin, raising safety risks and hidden dangers for inland waterways. The demand for "prevention and timely response" in waterway management is becoming more urgent. The Changjiang Nanjing Waterway Bureau will continue to deepen the linkage application of "Waterway GO+ Video Monitoring," focusing on iterative upgrades such as increasing monitoring point density, optimizing intelligent recognition algorithms, and integrating drone inspections, striving to enhance the full-chain management capacity of "prediction, forecasting, and early warning" in waterway monitoring to safeguard the safe and smooth operation of the Yangtze River Golden Waterway with more precise monitoring methods.
