How does the marine multi-function terminal ensure navigation safety?
Publish Time: 2025-04-08
In the wave of digital transformation in the shipping industry, the marine multi-function terminal has become the core equipment for ensuring navigation safety with its integrated and intelligent technical advantages. The terminal integrates functions such as positioning navigation, communication warning, personnel management and environmental monitoring to build a safety protection system covering the entire navigation process.1. Accurate positioning and collision avoidance warning: building the cornerstone of navigation safetyThe marine multi-function terminal is equipped with a Beidou/GPS dual-mode positioning system with a positioning accuracy of up to meters. Taking the Three Gorges section of the Yangtze River as an example, the terminal receives domestic Beidou satellite signals and outputs the ship's position, speed and heading data in real time, with an error of less than 1 meter, which is 50% higher than the traditional GPS positioning accuracy. With the cooperation of the ship automatic identification system (AIS), the terminal can receive dynamic information of other ships within a radius of 20 nautical miles, and combine the electronic chart (ECS) data to predict the risk of collision through intelligent algorithms. When the distance between the two ships is less than the safety threshold, the terminal automatically triggers an audible and visual alarm and generates a collision avoidance suggestion plan, shortening the collision warning response time to seconds.In complex waters, the terminal's radar echo enhancement function can identify obstacles within 12 nautical miles and determine the target's movement trend through Doppler frequency shift technology. For example, in the Baimu reef waters in Zhoushan waters, the terminal uses an integrated intelligent maritime safety assurance system to issue graded alarms to ships entering the warning area to avoid reef accidents. Data shows that after the terminal was installed in this area, the ship's reef rate dropped by 80%.2. Personnel management and emergency response: building a solid safety linePersonnel management is a key link in navigation safety. The terminal integrates face recognition, fingerprint recognition and second-generation ID card reading technology to achieve rapid verification of crew identity. In the ship lock declaration scenario, the system can automatically compare crew qualification information, shorten the verification time from 10 minutes manually to 30 seconds, and increase the verification accuracy to 99.9%. At the same time, the terminal monitors the crew's heart rate, blood pressure and other physiological indicators in real time through wearable sensors. When signs of fatigue driving are detected, it immediately issues an alarm and notifies the captain.In terms of emergency response, the terminal has a one-button alarm function, which can send distress information to maritime departments, nearby ships and rescue agencies simultaneously. In the actual test of the "Yuanda Times" ship in 2024, the Beidou shipborne multi-function terminal (MIBT) completed the sending of alarm signals within 10 seconds in the simulation exercise, which is 60% shorter than the response time of traditional equipment. The terminal also supports emergency communication relay. When the public network signal is lost, it can maintain contact with the outside world through the Beidou short message function.3. Environmental monitoring and compliance management: escort green shippingAs environmental protection regulations become stricter, the environmental monitoring function of the terminal is becoming more and more important. The ship exhaust emission monitoring module it carries uses laser spectroscopy technology to detect the concentration of sulfur oxides and nitrogen oxides in real time, with a data error of less than 5%. In the Yangtze River Basin, the terminal has been connected to the ship water pollutant emission control standard monitoring system to record the discharge of oily sewage and domestic sewage throughout the process to ensure compliance.In response to the needs of ship sewage exhaust monitoring, the terminal generates digital supervision reports by integrating water quality sensors and gas analyzers. For example, in the Three Gorges Dam area, the terminal can analyze the emission data of 500 ships in real time and automatically trigger the law enforcement process when abnormalities are found. In addition, the terminal's anti-pollution equipment operation monitoring function can remotely detect the operating status of equipment such as oil-water separators and incinerators, reducing the risk of human tampering.4. Intelligent operation and maintenance and data-driven: Improving safety efficiencyThe terminal uses the Internet of Things (IoT) technology to realize equipment status self-inspection, regularly collect sensor data and upload it to the cloud. Based on machine learning algorithms, the system can predict equipment failure cycles and issue maintenance reminders 72 hours in advance. In the practice of the Yangtze River Navigation Administration, the terminal's predictive maintenance function reduces equipment failure rates by 40% and operation and maintenance costs by 30%.The big data analysis platform conducts in-depth mining of navigation data to generate decision support tools such as waterway congestion index and risk warning model. For example, by analyzing the ship trajectory data sent back by the terminal, high-risk sections can be identified and route planning can be optimized to reduce the probability of accidents.The marine multi-function terminal takes technology integration innovation as its core, and builds a comprehensive and three-dimensional navigation safety protection system through functions such as precise positioning, intelligent warning, personnel management and environmental monitoring. With the popularization of Beidou-3 global networking and 5G technology, the real-time and reliability of terminals will be further improved, providing solid guarantee for the development of smart shipping.
