Description

Technical Field

[0001] The present invention relates to the technical field of waterway safety early warning, and in particular to a waterway safety early warning system. Background Art

[0002] With the booming development of global trade, the shipping industry has become a key link between various regions in the global trade process. However, the ocean is vast and sparsely populated. Once a shipping vessel encounters danger while sailing in the vast ocean, it is difficult to get rescue from external forces in a short period of time. Therefore, the safety of ships during shipping will receive special attention.

[0003] When sailing in the ocean, one of the most important factors threatening the safety of ships is extreme weather. Therefore, it is particularly important for transport ships to obtain timely and accurate weather conditions in each section of the route they are going to pass through. The existing method of obtaining weather conditions in each section of the route is usually to obtain route weather information through regional meteorological centers in various regions along the route.

[0004] However, when the navigation route is long, it is necessary to obtain weather conditions released by multiple regional meteorological centers, and the weather information released by regional meteorological centers in various regions is relatively scattered, which makes it inconvenient for users to timely and accurately obtain and analyze weather information at different locations on the route, which may easily lead to the inability to obtain information about possible adverse weather conditions in the route ahead in a timely manner, and then lead to the inability to adjust the route in time to avoid possible adverse weather conditions, which seriously affects the navigation safety during trade shipping. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a waterway safety warning system, which solves the problem that the existing method of obtaining waterway meteorological information is not convenient for users to obtain and analyze weather information at different locations on the waterway in a timely and accurate manner, which easily leads to the inability to obtain information on possible adverse weather conditions in the waterway ahead in a timely manner, seriously affecting the navigation safety in the trade shipping process.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A waterway safety warning system, comprising a meteorological information collection device installed on a shipping vessel, and also comprising a meteorological information acquisition unit, a meteorological information comparison unit, a reference condition input unit, a safety status analysis unit and a warning information sending unit;

[0008] The meteorological information collection device is used to detect and collect meteorological information of the waterway through which the ship passes during navigation, and the meteorological information collection device is connected to the meteorological information acquisition unit;

[0009] The meteorological information comparison unit is used to compare the acquired real-time meteorological information of each section in the waterway when the ship is sailing with the meteorological forecast information of the same section and the same time issued by the meteorological forecast center in each area of ​​the waterway;

[0010] The reference condition input unit is used to collect and obtain various other non-weather conditions that affect the navigation safety of ships;

[0011] The safety situation analysis unit is used to analyze whether to generate warning information by integrating the weather information of the section that the ship is about to sail to and other reference conditions. The safety situation analysis unit is connected to the weather information comparison unit, the weather forecast information issuing module of each regional weather forecast center and the reference condition input unit;

[0012] The warning information sending unit is used to send the generated warning information to the ship that is about to arrive at the section where danger may occur, and the warning information sending unit is connected to the safety status analysis unit.

[0013] Preferably, the meteorological information collection equipment includes temperature sensors, wind speed and direction meters, rainfall sensors, temperature and humidity sensors, visibility sensors and ocean current sensors installed on the sailing ship. The advantage of such a configuration is that it can timely monitor meteorological information that may affect navigation safety during navigation. Then, the meteorological information can be sent to the meteorological information comparison unit and the local regional meteorological forecast center, thereby providing accurate and reliable meteorological information for waterway navigation safety, thereby improving the navigation safety of ships sailing in the waterway.

[0014] Preferably, the non-weather conditions to be input by the reference condition input unit include the duration of the extreme weather forecast for the preceding segment, the planned sailing time of the vessel in question, and information on alternative waterways available for replacement near the preceding segment where extreme weather is forecast to occur. The advantage of such a setting is that, based on the duration of the extreme weather forecast and the information on alternative waterways, it is possible to decide whether to slow down and wait for the extreme weather in the preceding segment to disappear or to enter an alternative waterway to avoid extreme weather. This allows the efficiency of cargo navigation to be taken into account while ensuring navigation safety, thereby improving the reliability and practicality of the early warning system.

[0015] Preferably, the alternative channel information includes the length of the alternative channel, the expected passage time and weather information, etc. The advantage of such a setting is that the advantages and disadvantages of the ship entering the alternative channel and the predetermined channel can be comprehensively judged, and the best course adjustment decision can be made, thereby improving the reliability of the early warning system.

[0016] Preferably, the non-weather conditions to be input by the reference condition input unit also include the draft weight of the sailing vessel, the wind force level it can withstand and the wave height it can withstand. The advantage of such a setting is that the most suitable warning information level can be obtained according to the conditions of different ships themselves, thereby providing more accurate and targeted warning information and navigation suggestions, effectively assisting the person in charge of ship navigation to make reliable course adjustment decisions, and greatly improving the reliability and practicality of the warning system.

[0017] Preferably, the non-weather conditions to be input by the reference condition input unit also include cargo information loaded on the sailing vessel.

[0018] Preferably, the cargo information includes the wind force level and wave height that the cargo can withstand, and the cargo information also includes the suitable storage temperature, humidity and storage time of the cargo. The advantage of such a setting is that it can take into account the safety of the transported cargo while comprehensively considering the navigation efficiency and navigation meteorological safety, ensuring that the cargo can be delivered to the destination in a timely and safe manner, thereby greatly improving the reliability of the early warning system.

[0019] Preferably, the warning information generated by the safety status analysis unit is divided into three-level warning information, two-level warning information and one-level warning information in order from severe to mild according to the severity of the predicted dangerous situation.

[0020] Preferably, the third-level warning information is a general warning, and the person in charge of the ship receiving the third-level warning information can decide the sailing direction according to the actual situation. The second-level warning information is a serious warning, and the person in charge of the ship receiving the second-level warning information needs to ask the person in charge with higher authority to obtain the sailing direction of the subsequent ship. The first-level warning information is an extremely dangerous warning, and the person in charge of the ship receiving the first-level warning information must avoid entering the section where the first-level warning information is located or immediately exit the section where the first-level warning information is located. The advantage of this setting is that it can help the person in charge of ship navigation to screen the importance of warning information, reduce the difficulty of decision-making for the person in charge of navigation and improve the correctness of decision-making.

[0021] Preferably, after comparing the real-time meteorological information of each section in the waterway when the ship is sailing with the meteorological forecast information of the same section and the same time issued by each regional meteorological forecast center in the waterway, if the difference is greater than a set threshold, the information is sent to the safety situation analysis unit, and then the safety situation analysis unit generates warning information and sends it to the warning information sending unit. The advantage of such a setting is that the meteorological information of each section predicted by the regional meteorological forecast center can be corrected in time, ensuring that the sailing ship obtains more accurate and reliable meteorological information, thereby ensuring the safety of navigation to the greatest extent.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. Through the set weather information acquisition unit, reference condition input unit and safety status analysis unit, the navigation safety status of the preceding section can be evaluated by integrating meteorological information and some other conditions related to navigation safety, thereby generating more accurate and reliable waterway safety warning information, so that sailing ships can avoid waterways with potential safety hazards in a timely manner, effectively improving the safety of navigation.

[0024] 2. Through the reference condition input unit, the most suitable warning information level can be obtained according to the conditions of different ships, thereby providing more accurate and targeted warning information and navigation suggestions, effectively assisting the person in charge of ship navigation to make reliable course adjustment decisions, and greatly improving the reliability and practicality of the warning system.
