[0036] Compared with the prior art, the present invention has the following characteristics and beneficial effects:
[0037] By judging the relationship between the ship's hull rotation direction and the original water body action direction when the ship is stationary, the situation where the specific position area block of the underwater hull is subjected to the maximum water body force is determined, that is, the hull rotation direction and the original water body action direction are in an overlapping relationship, so as to intercept the corresponding target position area block. Under the action of the adjacent relationship between the hulls, the hull surface tension between different position area blocks has a certain effect of stabilizing the original form. Therefore, the surrounding hull area and the above-water hull to be detected located above the water surface are intercepted from the underwater hull to be detected. Then, the position relationship between the target position area block and the above-water hull to be detected is determined, that is, whether they are adjacent. If not, it is directly intercepted from the surrounding hull area. Take out four auxiliary detection area blocks in different positions to facilitate the subsequent correlation stabilization between adjacent area blocks. If so, cut out an auxiliary detection area block from the water hull to be detected, and cut out three auxiliary detection area blocks in different positions from the surrounding hull area. By making distinctive judgments in two situations, the traditional timeliness is avoided, and the conditional information in diverse situations is unified and processed in a single way, which increases the interference between information and the lack of information screening and simplification processing, which increases the probability of misjudgment of the final risk detection result. Through the above processing method, the regulatory rationality of the entire analysis and judgment process, the reliability of the detection and judgment results and the timeliness of risk warning are greatly enhanced.

[0038] Figure 1 It is a flowchart of a monitoring and response method based on ship safety mainly embodied in this embodiment.
[0039] Figure 2 This is a structural block diagram of a monitoring and response system based on ship safety mainly embodied in this embodiment. DETAILED DESCRIPTION
[0040] The present invention is further described in detail below with reference to the following examples.
[0041] Reference Figure 1 , a monitoring response method based on ship safety, the method comprising the following steps:
[0042] S1. Obtain the underwater hull to be detected of the ship located underwater, the rotation direction of the hull of the ship that is about to turn, and the original water body action direction of the ship when it is stationary. When the hull rotation direction coincides with the original water body action direction, cut out the target position area block from the underwater hull to be detected.
[0043] S2. Cut out the surrounding hull area adjacent to the target position area block from the underwater hull to be detected, and obtain the above-water hull to be detected located on the water. When the target position area block is not adjacent to the above-water hull to be detected, segment the first type of segmented area blocks from the surrounding hull area.
[0044] S3. When the target position area block is adjacent to the to-be-detected ship body on the water, a second type of segmented area block is comprehensively segmented from the surrounding ship body area and the to-be-detected ship body on the water.
[0045] S4. According to the reduction of the vertical force of the water body on the target location area block by the auxiliary detection area block in the first type of segmented area block or the second type of segmented area block, the vertical force actually exerted on the target location area block by the water body is predicted to obtain the main actual vertical force.
[0046] S5. The hull surface tension that has been affected by the water force and the hull surface tension that can be affected by the water force of the target position area block, the first type of segmented area block or the second type of segmented area block are predicted respectively to obtain the total tension value and the total tension value that can be affected. When the total tension value that has been affected is equal to the total tension value that can be affected, the hull damage risk warning information is output.
[0047] Specifically, the relationship between the ship's hull rotation direction and the original water body action direction when the ship is stationary is used to determine the situation where the specific position area block of the underwater hull is subjected to the maximum water body force, that is, the hull rotation direction and the original water body action direction are in an overlapping relationship, so as to intercept the corresponding target position area block, and under the effect of the adjacent relationship between the hulls, the hull surface tension between different position area blocks has a certain effect of stabilizing the original form, so the surrounding hull area and the above-water hull to be detected located above the water surface are intercepted from the underwater hull to be detected, and then the position relationship between the target position area block and the above-water hull to be detected is determined, that is, whether they are adjacent, if not, directly from the surrounding hull area Four auxiliary detection area blocks at different positions are intercepted in order to facilitate the subsequent correlation stabilization between adjacent area blocks. If yes, one auxiliary detection area block is intercepted from the water hull to be inspected, and three auxiliary detection area blocks at different positions are intercepted from the surrounding hull area. By making distinctive judgments in two cases, the traditional timely method is avoided, in which the conditional information under diverse situations is unified and processed in a single manner, which increases the interference between information, and the information is not screened and simplified, which increases the probability of misjudgment of the final risk detection result. Through the above processing method, the regulatory rationality of the entire analysis and judgment process, the reliability of the detection and judgment results and the timeliness of risk warning are greatly enhanced.
[0048] The specific step S1 includes the following sub-steps:
[0049] The underwater hull to be detected and the rotation direction of the hull of the ship that is about to rotate are obtained, and according to the underwater hull to be detected, the original water body action direction of the force in a vertical direction on the underwater hull to be detected in the static state of the ship is obtained.
[0050] When the hull rotation direction of different hull position area blocks in the underwater hull to be detected coincides with the original water body action direction, the preprocessing judgment situation is output.
[0051] According to the pre-processing judgment, a position area block corresponding to the pre-processing judgment is cut out from the underwater hull to be detected to obtain a target position area block.
[0052] Specifically, such as the direction of ship rotation (if it rotates 90° counterclockwise, it is marked with the letter A to facilitate subsequent example analysis), the original water action direction (that is, when the ship is in a stationary state, the directions of the water force acting on all position areas are perpendicular to each other, but the original water action directions of each position area are different, if a1, a2, and a3 are included), the pre-processing judgment situation (if the starting direction of the ship's rotation direction coincides with the direction of a1 when it just starts to turn, that is, a1 and A are in a straight line: 180° angle), and the target position area block (if the position area block corresponding to a1 is W1, then W1 is the target position area block, because at this time, the water force acting on W1 is the largest).
[0053] The specific step S2 includes the following sub-steps:
[0054] A surrounding hull area adjacent to the target position area block is cut out from the underwater hull to be detected.
[0055] The preprocessed tilt angle is obtained by counting the tilt angle formed between the hull turning direction and the original water direction to which the surrounding hull area belongs.
[0056] The main original force of the water body acting on the target position area block in a static state and the water body to be detected located on the water are obtained.
[0057] When the target position area block is not adjacent to the water ship body to be detected, the area judgment threshold is preset to one, and the preprocessing area is divided into four auxiliary detection area blocks with different positions and unequal areas to obtain the first type of segmented area blocks, and the total area of the first type of segmented area blocks is equal to the area judgment threshold one.
[0058] Specifically, such as the surrounding hull area (if it is Q, and Q surrounds W1, for example, W1 is a circular area, if Q is also a circular area, then Q is the outer large circular area, W1 is the inner small circular area, and the edge of W1 is connected to the inner edge of Q), the pre-processed tilt angle (that is, under the conditions of a1 and A, the angle formed between the original water body action direction of the area inside Q and A, the angle formed is extracted to be an inclination angle of no more than 45°, so the surrounding hull area corresponding to the inclination angle has a greater degree of stabilization of the auxiliary hull surface tension of W1. If the inclination angle is larger, it means that the degree of stabilization of the auxiliary hull surface tension is smaller. If the pre-processed tilt angles include B, C, D), the hull to be detected on the water (i.e., located directly above W1 and above the water surface: that is, the hull area not affected by the water force, if it is W2), when the target position area block is not adjacent to the hull to be detected on the water (because W2 cannot be used for subsequent auxiliary stabilization of W1 to cope with the water force, and the hull surface tension between the two does not have a direct correlation), the area judgment threshold is one (if it is twice the area of W1, because half of it can be used to cope with the water force itself, and half of it can be used to assist in stabilizing W1 to cope with the water force), the first type of segmented area blocks (including four auxiliary detection area blocks b1, b2, b3, and b4, which are adjacent to each other in pairs, and the total area is twice the area of W1).
[0059] The specific step S3 includes the following sub-steps:
[0060] When the target position area block is adjacent to the to-be-detected ship body on water, a pre-processed area having a coverage area smaller than an area determination threshold of one is cut out from the surrounding ship body area.
[0061] According to the preprocessing tilt angle and the main original force, the preprocessing area is divided into three auxiliary detection area blocks with different positions and unequal areas, and an area block for auxiliary detection is intercepted from the water hull to be detected, and the second type of segmented area blocks are output. The total area of the second type of segmented area blocks is equal to the area judgment threshold one.
[0062] Specifically, when the target position area block is adjacent to the ship hull to be detected on the water (so W2 can be used for subsequent auxiliary stabilization of W1 to cope with the force of the water body, and the surface tension of the hull between the two has a direct correlation), the second type of segmented area blocks (the explanation is the same as the first type of segmented area blocks, the difference is that, for example, b1, b2, and b3 are segmented from the preprocessing area, and b4 is segmented from W2. The four area blocks are adjacent to each other in pairs, and the total area is twice the area of W1).
[0063] The specific step S4 includes the following sub-steps:
[0064] Obtain the secondary original force of the water body and the rotation operation parameters of the ship in the three auxiliary detection area blocks located on the underwater ship body in the first type segmented area block or the second type segmented area block in a stationary state.
[0065] According to the pre-processed tilt angle, the secondary original force and the rotation operation parameters, the vertical water force acting on the three auxiliary detection area blocks located on the underwater hull in the first type of segmented area block or the second type of segmented area block is predicted to obtain the secondary actual vertical force, and the secondary buffering force dispersed horizontally to the target position area block by the three auxiliary detection area blocks located on the underwater hull in the first type of segmented area block or the second type of segmented area block.
[0066] According to the rotation operation parameters and the main original force, the vertical water force initially applied to the target position area block is predicted to obtain the initial main vertical force.
[0067] The initial main vertical force and the secondary buffer force are subtracted to obtain the main actual vertical force.
[0068] Specifically, such as the secondary original force (i.e., the water pressure on the ship when it is stationary, if the first type of segmented area block is used as an example: b1 (similarly, if the second type of segmented area is used as an example), if the secondary original force is F1, the statistics here are all for the hull area under water, because the water pressure of the hull area above water does not need to be considered), the rotation operation parameter (refers to the rotation speed, if the rotation speed is greater, the corresponding water pressure is greater), the secondary actual vertical force (if the secondary original force is proportional to the rotation operation parameter, then according to the associated conversion ratio value, the secondary original force after the conversion superposition is estimated. At this time, the secondary original force after the conversion superposition is The force is not all applied vertically on b1. According to the pre-processed inclination angle, the water force in the horizontal direction and the actual water-soil force in the vertical direction of the converted and superimposed secondary original force are calculated respectively. If they are s1, they are the secondary actual vertical force, and c1 is the secondary buffer force. The analysis steps for b2, b3, and b4 are the same. If they are s2 and c2, s3 and c3, s4 and c4 respectively), the initial main vertical force (if it is Z1, part of the force of the secondary buffer force in the horizontal direction offsets the effect, then the comprehensive water force in the direction with an inclination of 45° can be predicted, and then according to this inclination, the actual water force on W1 in the vertical direction is predicted, if it is Z2).
[0069] The specific step S5 includes the following sub-steps:
[0070] The secondary original tolerable tension value of the hull surface tension affected by the water body is obtained for each of the first type segmented area block or the second type segmented area block, and the primary original tolerable tension value of the hull surface tension affected by the water body is obtained for the target position area block.
[0071] According to the secondary actual vertical force, the three auxiliary detection area blocks located on the underwater hull in the first type of segmented area blocks or the second type of segmented area blocks are predicted to have lost a tension value of one on the surface tension of the hull, and the secondary original tolerable tension value and the tolerable tension value of one are subtracted to obtain the tolerable tension value of one.
[0072] According to the main actual vertical force, the tension value 2 of the target position area block loss hull surface tension is predicted, and the main original tolerable tension value and the tension value 2 are subtracted to obtain the tolerable tension value 2.
[0073] The total tension value is obtained by adding the tension value one and the tension value two.
[0074] The tolerable tension value 1 and the tolerable tension value 2 are summed to obtain the tolerable total tension value.
[0075] When the total tension value that has been sustained is equal to the total tension value that can be sustained, the hull damage risk warning information is output.
[0076] Specifically, such as the secondary original tolerable tension value, the primary original tolerable tension value (if they are f1 and z1 respectively), the tension value one (that is, according to the hull surface tension-pressure conversion ratio matching table, the corresponding loss hull surface tension is matched according to the secondary real vertical force, if it is h1, here h1 is the sum of the loss hull surface tension of each of the first type of segmented areas, the above f1 and z1 are the same), the tolerable tension value one (if f1-h1 is f2), the tolerable tension value two (the explanation is the same as the tolerable tension value one, no further explanation is given here, If it is z2), the total tension value that has been subjected to (i.e. f1+z1 if it is R1), the total tension value that can be subjected to (i.e. f2+z2 if it is R2), and the hull damage risk warning information (if R1 is equal to R2, it means that the hull surface tension of W1 is at the critical value of damage; if R1 is greater than R2, it means that the hull surface tension of W1 is damaged, and under the auxiliary tension stabilization effect of b1, b2, b3, and b4, it has also reached the critical value. Therefore, timely early warning notification is required at this time to notify the technical personnel to take timely response measures).

When the hull rotation direction coincides with the original water body action direction, a target position area block is intercepted from the underwater hull to be detected; the surrounding hull area adjacent to the target position area block is intercepted from the underwater hull to be detected by the auxiliary detection area interception unit 1, and the surface hull to be detected located above the water is obtained. When the target position area block is not adjacent to the surface hull to be detected, a first type of segmented area block is segmented from the surrounding hull area; when it is determined by the auxiliary detection area interception unit 2 that the target position area block is adjacent to the surface hull to be detected, a first type of segmented area block is segmented from the surrounding hull area The second type of segmented area blocks are comprehensively segmented from the area and the surface ship to be detected; the vertical force of the water body on the target position area block is reduced by the auxiliary detection area block in the first type of segmented area blocks or the second type of segmented area blocks, and the vertical force of the water body actually exerted on the target position area block is predicted by the force comprehensive analysis unit to obtain the main actual vertical force; the hull surface tension that has been lost by the water body force and the hull surface tension that can be exerted by the water body force of the target position area block, the first type of segmented area blocks or the second type of segmented area blocks are predicted by the risk judgment and early warning unit to obtain the total tension value and the total tension value that can be exerted; when the total tension value that has been exerted is equal to the total tension value that can be exerted, the hull damage risk early warning information is output.
