According to statistics, more than 850 billion yuan has been invested in canal projects nationwide in the past three years.
Locally, Jiangsu will invest nearly 3.5 billion yuan in the construction of digital highway and waterway transportation infrastructure projects in the next three years.
Ningbo will invest 500 million yuan in the construction of highway and waterway transportation infrastructure digitization project in the next three years.

Canal construction is accelerating, but safety problems such as ship collision with bridges and speedboat smuggling are frequent and challenging.
How to use technical means to strengthen the safety of the canal?
Nanoradar lays out water security and weaves the "safety net" of the canal with "small radar".
Analysis of traditional water security technology
Water area security solution based on millimeter wave radar
The scheme has the advantages of all-day, all-weather, long coverage and rich target information. Through track tracking and management, it can actively warn all kinds of dangerous behaviors of ships, avoid bridge collision, and provide key information for law enforcement departments to help them pursue smuggling and drug trafficking vessels and ensure the safety of the canal.
Nanoradar WTC261-3000 Surface Surveillance Radar, a New Defense Line for Canal Safety
WTC261-3000 is a surface surveillance radar with a ship measuring distance of 3000m. The radar can monitor various ship targets moving on the water surface all day long, and accurately detect the distance, angle and other information of the targets. With cognitive radar technology, it can achieve 99.999% water clutter filtering, which brings great convenience to surface monitoring and management.
●The algorithm optimization can reduce the false alarm rate in rainy and windy weather.
●The algorithm design can automatically filter the clutter on the water surface and prevent the false alarm caused by clutter interference.
Through environmental learning, false alarm suppression and clutter filtering, the average false alarm of less than or equal to one time in a day can be achieved under wind power of three levels or below.
high reliability, the ultimate experience
●Strong environmental adaptability: IP66 high protection grade, waterproof and dustproof, filtering close-range mosquitoes, shock and fall resistance, stable operation in extreme environment of -40 ℃ ~ 70 ℃, 7 × 24h all-weather real-time protection
●Adaptive calibration: The built-in attitude sensor of the radar supports the adaptive calibration of RVSM radar installation information without manual calibration.
●Ground coordinate information output: GPS/Beidou is supported, and the ground coordinate information of the target can be directly output to facilitate the visual management of the equipment by the customer.
●Anti-blocking: It can effectively prevent malicious blocking and shielding of radar detection.
Best application practices
Bridge anti-collision application practice: radar fusion video surveillance, sound and light alarm, data transmission and other systems can give safety warning to passing ships near the bridge, effectively reduce the probability of bridge collision by ships during operation, and ensure the safety of the bridge.
Selected cases：
Bridges in Guangxi
●Application practice of smart gate on water: radar fusion AIS, thermal imaging camera and other systems can realize automatic detection, intelligent identification, safety warning, illegal forensics and other functions in the process of ship entering and leaving the gate, providing real-time, comprehensive and visual ship dynamics at the gate for ship management in inland waterways.
