On January 8, the Haikou Navigation Marks Office of the South China Sea Navigation Guarantee Center of the Ministry of Transport (hereinafter referred to as the "Haikou Navigation Marks Office") successfully completed the replacement and maintenance of the No. 1 light buoy in Xiuying Port, Haikou, and installed the high-tech "Chinese core" Beidou Telemetry and remote control lights and Beidou AIS entity navigation beacon. So far, before the Spring Festival transport, the Haikou Navigation Marks Office has achieved full coverage of the Qiongzhou Strait navigation mark telemetry and remote control system and the key waters AIS Beidou entity navigation mark, which has effectively improved the comprehensive guarantee capability of the Qiongzhou Strait ro-ro passenger transportation service, which will be the beginning of 2020. Qiongzhou Strait passenger transportation during the Spring Festival provides more reliable navigation aid services.

112 light buoy upgrade and maintenance

The 2020 Spring Festival Transport will start on January 10 and end on February 18, a total of 40 days. The Qiongzhou Strait is one of the key areas of my country's waterway transportation safety supervision. It is of great significance to fight for the Spring Festival transport and ensure the safety of the people's livelihood.

In order to enable ships to identify and grasp the status of navigational beacons on the Qiongzhou Strait ro-ro passenger transportation channel. On the eve of the Spring Festival Transport, the Haikou Navigation Marks Office carried out lifting and maintenance of the light buoys of the Qiongzhou Strait ro-ro passenger transportation channel, installing Beidou telemetry remote control terminals, and setting up AIS Beidou entity navigation beacons to provide more information for ships to identify the Qiongzhou Strait ro-ro passenger transportation channel. Convenient conditions, enhance the navigation and navigation efficiency of the water area, and strive to improve the comprehensive support capability of transportation services.

On the morning of January 8th, in the Xiuying Port Channel of Haikou, the Haikou Navigation Marks Office was upgrading and maintaining the No. 1 light buoy at Xiuying Port. The whole process of the lifting and launching of the light buoy can be directly hit on the spot...To improve the light buoy For navigation efficiency, the Haikou Navigation Marks Department has continuously optimized the light buoys. After taking safety measures, the first-line navigation mark staff skillfully climbed the light buoys, quickly replaced the light buoys with new navigation facilities, and installed the light buoy solar power supply system and AIS. The Beidou physical navigation mark was then tested one by one, and it took less than an hour to bring the show to a new look. It is reported that all light buoys in Qiongzhou Strait have been upgraded and maintained.

Ruan Jiaxiao, Section Chief of the Operational Guarantee Section of the Haikou Navigation Marks Office of the South China Sea Navigation Guarantee Center of the Ministry of Transport, told reporters excitedly that in the past 4 months, the Haikou Navigation Marks Office organized the upgrading and maintenance of 112 light buoys and 6 lighthouses (piles) in the Qiongzhou Strait. The navigational light buoys and lighthouses (piles) on the Qiongzhou Strait passenger transportation channel are completely renewed, and the full coverage of the Qiongzhou Strait waters' navigation beacon telemetry and remote control system and the key waters AIS Beidou physical navigation beacon are fully covered, and the navigation effect is more obvious. He pointed out that the upgrade of light buoys and lighthouses will better cope with the upcoming Spring Festival transportation, creating a "safe and unobstructed" navigable environment for citizens and tourists traveling to and from the Qiongzhou Strait, and illuminating the Qiongzhou Strait for returning home during the Spring Festival. road.

"China Core" remote control telemetry equipment to achieve full coverage

Ruan Jiaxiao said that the biggest highlight of this navigation aid upgrade is the use of the Beidou remote control telemetry system based on the Beidou satellite system. During the upgrade and maintenance of the light buoys, the Haikou Navigation Mark Office installed Beidou telemetry remote control terminals on 86 light buoys in the Qiongzhou Strait, realizing full coverage of the Qiongzhou Strait navigation mark remote control system. He introduced that in the waters of the Qiongzhou Strait far away from the coastline, the navigation mark terminal transmits information through the operator or VHF channel due to the antenna height and power, and there are factors such as weak and unstable signals. But the Beidou system signal can completely cover the Qiongzhou Strait, and the signal transmission through the Beidou system can effectively solve the problem of signal coverage of the navigation mark telemetry and remote control system.

He further explained that some of the light fixtures were only equipped with conventional telemetry and remote control light fixtures, and it was difficult to monitor the operation of navigation marks without signal in remote areas in real time. Once a navigation mark failure occurs, it can only be found by the navigation mark personnel on regular inspections or depends on the crew. The report, which easily caused the faulty navigation mark to not be repaired in time, and did not play its due role in navigation for passing ships. The realization of the full coverage of the navigation mark telemetry and remote control this time has two main benefits: one is to improve the management efficiency of the navigation mark, so that the navigation mark personnel can grasp the working status of the navigation mark in real time, and can carry out the daily management of the navigation mark in a more targeted manner and implement refined management. . The second is to increase the normal use rate of navigation marks. Through the navigation mark telemetry and remote control system, navigation mark management personnel can find abnormal navigation marks in time, and quickly organize emergency repairs to ensure that all navigation marks are in normal working conditions and provide reliable guidance for ships in a timely and efficient manner. Navigation assistance services.

Navigation is clearer, safer and more secure

"After the light buoy is upgraded and maintained, the visual effect is better, and the reliability of the navigation mark is higher. Even if the sea conditions are bad, the AIS Beidou entity navigation mark can help identify the navigation mark information and route information, and our ships will be more convenient and more convenient to navigate. It’s safer.” The captain xxx, who often sails in the Qiongzhou Strait, said that in foggy days or poor visibility at night, ships generally rely more on shipborne radar and AIS system for navigation. With the upgrade of the light buoy, the ship passes the AIS system. , Shipborne radar and other methods are more effective in identifying and displaying navigation marks, which further improves the navigation mark recognition effect in poor visibility weather, and provides more effective help for ships to identify waterways and routes.

According to Ruan Jiaxiao, the Qiongzhou Strait is the “golden waterway” for busy maritime transportation. In 2019, the Ministry of Transport officially released the "Three-year Action Plan for Improving the Capacity of Roll-on Passenger Transport Services in the Qiongzhou Strait (2019-2021)". It is of great significance to build a pilot free trade zone and a free trade port with Chinese characteristics, and comprehensively deepen reform and open up.

"In order to improve the comprehensive guarantee capacity of the Qiongzhou Strait ro-ro passenger transportation service, to serve the construction of a free trade zone (port) in Hainan, and to actively respond to the "Outline for the Construction of a Powerful Transportation Country", the Haikou Navigation Mark Office upgraded and maintained the light buoy to optimize the Qiongzhou Strait ro-ro passenger transportation channel The navigation mark is equipped with cloth, and the multi-functional navigation mark system is set up to write the article on the transportation of China's aviation insurance." Ruan Jiaxiao said that at present, the upgrade and maintenance of the light buoy has been completed. In the next step, the Haikou Navigation Mark Office will select 6 navigation marks in key locations in the Qiongzhou Strait for multi-function In the pilot construction of navigation aids, through the installation of visibility meters, wind direction meters, ocean current meters, video and other equipment, the hydrological and meteorological information (wind speed, wind direction, flow rate, visibility) and video information of key locations in the water area are collected, and the information platform is used for port and shipping units, Ships provide real-time hydrology, weather, navigation aids and other information in the water area, and provide reference data for ro-ro passenger ships on the Qiongzhou Strait. The adjustment of navigational standard configuration for the adjustment of the Qiongzhou Strait ship routing system is also in progress. At present, the first draft of the adjustment plan has been completed.

In addition, the reporter was also informed that the Haikou Navigation Marks Office will also strengthen its leading role in party building. By organizing the Haikou Navigation Marks Management Station and the Xuwen Navigation Marks Management Station of the Zhanjiang Navigation Marks Office to carry out paired construction, it will realize resource sharing, information exchange, and complementary advantages, and work together to create the "Strait Beacon". "Guarantee Voyage" Qiongzhou Strait air insurance service brand, and jointly enhance Qiongzhou Strait passenger ro-ro passenger transportation service guarantee capabilities.
