Description

Technical Field

[0001] The invention belongs to the technical field of ship navigation, and in particular relates to an inland river ship risk identification and early warning device and an evaluation method thereof. Background Art

[0002] Inland waterways belong to the category of narrow waterways. Due to differences in navigation environment and other factors, navigation conditions are much more complicated than those at sea. With the development of the shipping economy, more and more river-to-sea direct ships are entering ports along the rivers for loading and unloading operations. If the captain and driver of an ocean-going ship enter the inland waterway for the first time, they do not understand the inland waterway and navigation characteristics, do not carefully check the section information, study the waterway conditions, and are not prepared for potential dangers and emergencies, which will lead to urgent situations. Due to the influence of various environmental factors, the inland waterway is changing to varying degrees all the time. Therefore, even if the captain and driver of the ocean-going ship have an in-depth understanding and preparation for the waterway in advance, there will still be certain navigation risks in the actual navigation process of the ship. Under the existing navigation conditions, there is no corresponding navigation risk assessment and early warning device for different ships to conduct real-time risk assessment of the waterway, and there is no systematic assessment method for the captain and driver of the ocean-going ship to make an assessment reference, which makes the probability of accidents occurring during the navigation of the ship higher, and the accidental risk of navigation is greater, which seriously affects the development of inland waterway transportation.

The water pressure monitor is deposited on the river bottom, the flow rate monitor and the salinity monitor are suspended in the river water, the water wave monitor floats on the water surface, and the underwater imaging machine is set underwater at the riverside.

[0033] This embodiment also discloses an assessment method using an inland waterway vessel risk identification and early warning device, comprising the following steps:

[0034] S1, start the device, the assessment system (1) and the early warning system (2) are initialized;

[0035] S2, the assessment system (1) and the early warning system (2) are loaded into the assessment work procedure;

[0036] S3, the evaluation system (1) program runs to confirm whether the wireless connection between the evaluation system (1) and the early warning system (2) is successful. If the connection is successful, proceed to S4. If the connection fails, return to S2.

[0037] S4, the onshore collection module (11) and the river collection module (12) respectively collect data on the onshore and river environments of the route, and send the corresponding collected data to the integrated processing system (13) for summarization and storage in the integrated processing system (13);

[0039] S6, the wireless data receiver (21) sends the received wireless data to the computer (22), and the information management system (23) in the computer (22) processes the data to obtain the risk factor of the corresponding ship sailing on the route section;

[0040] S7, when the risk factor is low or no risk is found, the ship can continue to sail and proceed to S8, when the risk factor is high, the alarm (24) sounds an alarm, the ship stops sailing and waits for the risk to be eliminated or docks;

[0041] S8, when the sailing ship enters the next route section, the ship's warning system (2) disconnects from the wireless connection with the assessment system (1) of the previous route section, and connects to the assessment system (1) of the next route section wirelessly, and then proceeds to S4, which is repeated in sequence.

[0042] The risk assessment result of the ship sailing on each route segment is calculated according to the following formula: R = R1*R2*D;

[0044] The onshore environmental monitoring data is obtained by the wind speed monitor (111), the wind direction monitor (112), the fog monitor (113), the temperature monitor (114), and the rainfall monitor (115) of the onshore acquisition module (11), and the onshore environmental monitoring data integration result is calculated by the following formula: R1 = 0.1Vcos a*0.5M*(1.8C+32)*(0.2H+1);

[0045] Wherein V is the wind speed monitored by the wind speed monitor (111), a is the angle between the ship's sailing direction and the center line of the route section, M is the fog concentration, C is the ambient temperature in degrees Celsius, and H is the rainfall.

[0046] The river environment monitoring data is obtained by the water pressure monitor (121), flow rate monitor (122), wave monitor (123), and salinity monitor (124) of the river acquisition module (12). The underwater imaging device (125) directly takes color pictures of the river environment and sends them to each ship, so that the navigation personnel can directly understand the river situation and make risk judgments. The integrated result of the river environment monitoring data is calculated by the following formula: R2 = 0.03P / ρ / g + 0.4S + 2B + 1.3U;

[0047] Where P is the water pressure, ρ is the density of river water, g is the gravity constant, S is the river flow velocity (with the navigation direction as the positive direction), B is the wave frequency, and U is the salinity of river water.

[0048] The ship's own navigation condition parameters are calculated by the following formula: D = 0.03Q*6.5L*W*Z;

[0049] Where Q is the deadweight of the ship, L is the draft of the ship, W is the width of the ship, and Z is the length of the ship.

[0050] The above calculation formula is loaded into the information management system (23) for operation and calculation, and finally the risk assessment result is obtained. The final value obtained by the risk assessment result can be judged by referring to the following risk assessment conclusion table. The risk assessment conclusion table is as follows:

[0051] Risk assessment calculation results Risk Assessment Conclusion 0-300 No risk 300-500 Lower risk 500-800 Moderate risk 800-1000 Higher risk More than 1000 No sailing
