Application Case of Vessel Monitoring and Early Warning System for Zhuangli Reservoir in Zaozhuang, Shandong

Customer Background Located in Zaozhuang City, Shandong Province, Zhuangli Reservoir is the only large-scale reservoir newly built in Shandong Province in the past 30 years, and undertakes important functions such as flood control, water supply and ecological regulation. The reservoir has a vast water area, complex shorelines, and is surrounded by multiple villages and tourism and leisure areas, making daily management tasks arduous. However, it mainly relies on manual patrols, patrol boats and drones, with insufficient intelligence, and still has coverage blind spots and bottlenecks in regulatory efficiency. Challenges • Low efficiency of traditional patrols: It is difficult to achieve full-area coverage relying on manual patrols and patrol boats, and activities such as illegal fishing, unauthorized fishing, and swimming have been repeatedly banned. • Difficult supervision at night and in bad weather: At night and in rainy and foggy weather, the effectiveness of manual visual inspection and ordinary video surveillance drops significantly, resulting in long-term supervision blind spots. • Lack of active early warning capability: Traditional methods mainly rely on passive response, which cannot detect abnormal activities of suspicious vessels in real time, and is difficult to achieve pre-event prevention. • Difficult law enforcement and evidence collection: It is difficult to quickly fix evidence after discovering violations, which affects the effect of law enforcement. Solutions In response to the above pain points, Huiershi has built a key water area monitoring and early warning system, with phased array radar as the core, to build a "water surface electronic fence" covering the entire water area: • Phased array radars and high-definition photoelectric cameras are deployed at key positions on the shore to achieve large-scale coverage of waters with a radius of 3-5 kilometers, and seamlessly monitor targets such as intruding vessels. • The radar is not affected by rain, snow or night, and actively scans 24/7, outputting the target's position, speed and heading in real time. • The photoelectric dome camera links according to the radar coordinates, automatically locks and identifies the invading vessel, and captures high-definition video for forensics. • The edge computing unit fuses multi-source data in real time, integrates forensic information and uploads it to the management and control platform. • The system supports flexible delineation of electronic fences, and automatically triggers an alarm for vessels that break into no-fishing zones and water source protection zones. Application Effect • All-weather coverage without dead ends: The radar is not affected by day and night, rain and fog, and realizes uninterrupted monitoring of the entire water area, and has detected more than 5,000 batches of various vessel activities in total. • Intelligent linkage active early warning: automatically monitors intruding vessels, and gives real-time alarms and pushes pictures to vessels that break into restricted areas. • Violations have decreased significantly: Incidents of illegal fishing and unauthorized fishing have dropped by more than 80% year-on-year, and the protection effect of the reservoir water source is obvious. Customer Evaluation "The HURYS system has truly enabled us to achieve a leap in reservoir management from 'human wave tactics' to 'intelligent supervision'. It can see clearly around the clock, and violators cannot escape. Both reservoir safety and management efficiency have reached a new level." —— Relevant person in charge of Zhuangli Reservoir Management Service Center
