Description

Technical Field

[0001] This invention relates to the field of radar navigation technology, and more specifically, to an anchor position monitoring method, device, electronic device, and computer storage medium. Background Technology

[0002] Currently, navigation radar software has an anchor point monitoring function, which usually corresponds to different anchor point monitoring methods. In the existing technology, during the monitoring process, it is necessary to switch and select the anchor point monitoring method. This makes the selection of the anchor point monitoring method too subjective and requires the user to manually select it, which is inconvenient for the user. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an anchor position monitoring method, device, electronic device and computer storage medium, which aims to solve at least one of the above-mentioned technical problems.

[0004] In a first aspect, the technical solution of the present invention to solve the above-mentioned technical problems is as follows: an anchorage monitoring method, the method comprising: Based on the equipment status of the ship's positioning equipment, the anchor position monitoring method is determined. The anchor position monitoring method is either a first monitoring method or a second monitoring method. The first monitoring method is a monitoring method that uses the ship's location at the activation time as a reference point. The second monitoring method is a monitoring method that uses any tracking target that meets the set tracking conditions as a reference point. The activation time is the time when the anchor position monitoring function is activated. According to the anchorage monitoring method, the distance between the monitored target and the reference point is determined in real time, wherein the monitored target is the ship itself or other tracked targets; Based on the distance value and the preset alarm threshold, the monitoring of the monitored target is achieved.

[0005] The beneficial effects of the present invention are: the first monitoring method or the second monitoring method can be flexibly selected as the anchor position monitoring method according to the equipment status of the positioning equipment of the ship, so as to determine the distance value between the monitored target and the reference point in real time according to the anchor position monitoring method, thereby realizing the monitoring of the monitored target based on the distance value and the preset alarm threshold value.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the aforementioned equipment status includes a first status where the vessel's position is obtained through the positioning device, and a second status where the vessel's position cannot be obtained through the positioning device. Determining the anchorage monitoring method based on the equipment status of the vessel's positioning device includes: If the device status is the first status, then the first monitoring method is determined as the anchor monitoring method; If the device status is the second status, then the second monitoring method is determined as the anchor monitoring method.

[0008] The beneficial effect of adopting the above-mentioned further solution is that when the positioning device cannot obtain the position of the ship, the second monitoring method can be used as the anchor position monitoring method. In this way, regardless of whether the positioning device can obtain the position of the ship, real-time monitoring of the anchor position can be guaranteed.

[0009] Furthermore, if the monitored target is the vessel itself, the method of determining the anchorage monitoring based on the equipment status of the vessel's positioning equipment includes: Based on the ship's navigation status and the equipment status, determine the anchorage monitoring method.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that, when the monitored target is the ship itself, the anchor position monitoring method can be determined in combination with the ship's navigation status, so that the monitored target can be better monitored based on the determined anchor position monitoring method.

[0011] Furthermore, the above-mentioned method of determining the distance between the monitored target and the reference point in real time according to the anchor monitoring method includes: If the anchorage monitoring method is the first monitoring method, and the monitored target is the ship itself, the ship's movement distance is calculated in real time based on the ship's position at the activation time and the ship's position at the current time, and the movement distance is used as the distance value between the monitored target and the reference point. If the anchorage monitoring method is the first monitoring method, and the monitored target is another tracking target, the distance between the other tracking target and the ship is calculated in real time based on the position of the other tracking target and the position of the ship at the same time. If the anchorage monitoring method is the second monitoring method, and the monitored target is the ship itself, the distance between the ship and the reference point is calculated in real time based on the ship's position at the activation time, the reference point's position at the activation time, the ship's position at the current time, and the reference point's position at the current time. If the anchor monitoring method is the second monitoring method, and the monitored target is another tracking target, the distance between the other tracking target and the reference point is calculated in real time based on the position of the other tracking target at the activation time, the position of the reference point at the activation time, the position of the other tracking target at the current time, and the position of the reference point at the current time.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that, under different monitoring methods and different monitored targets, different calculation methods are used to determine the distance value between the monitored target and the reference point, making the determined distance value more accurate.

[0013] Furthermore, the monitoring of the target based on the distance value and the preset alarm threshold includes: An alarm message is generated when the distance value exceeds the alarm threshold.

[0014] The advantage of adopting the above-mentioned further solution is that when the distance value exceeds the alarm threshold, an alarm message can be generated in real time, so that the operator can silence the alarm sound by pressing a button or other means.

[0015] Secondly, in order to solve the above-mentioned technical problems, the present invention also provides an anchorage monitoring device, the device comprising: Anchorage monitoring mode determination module is used to determine the anchorage monitoring mode based on the equipment status of the ship's positioning equipment. The anchorage monitoring mode is either a first monitoring mode or a second monitoring mode. The first monitoring mode is a monitoring mode that uses the ship's location at the activation time as a reference point. The second monitoring mode is a monitoring mode that uses any tracking target that meets the set tracking conditions as a reference point. The activation time is the time when the anchorage monitoring function is activated. The distance value determination module is used to determine the distance value between the monitored target and the reference point in real time according to the anchor position monitoring method, wherein the monitored target is the ship or other tracking targets; The monitoring module is used to monitor the target based on the distance value and a preset alarm threshold value.

[0016] Thirdly, in order to solve the above-mentioned technical problems, the present invention also provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the anchor monitoring method of the present application.

[0017] Fourthly, in order to solve the above-mentioned technical problems, the present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the anchor monitoring method of the present application.

[0018] Additional aspects and advantages of this application will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of this application. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments of the present invention will be briefly introduced below.

[0020] Figure 1 A flowchart illustrating an anchor position monitoring method according to an embodiment of the present invention; Figure 2 A flowchart illustrating another anchorage monitoring method provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of an anchor position monitoring device according to an embodiment of the present invention; Figure 4 This is a schematic diagram of the structure of an electronic device provided in one embodiment of the present invention. Detailed Implementation

[0021] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0022] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] The solution provided in this invention can be applied to any application scenario that requires monitoring of the target using radar navigation software with anchor position monitoring function. The solution provided in this invention can be executed by any electronic device, such as a user's terminal device, for example, a terminal device with radar navigation software installed, including at least one of the following: smartphone, tablet computer, laptop computer, desktop computer, smart speaker, smartwatch, smart TV, and smart vehicle device.

[0024] This invention provides a possible implementation, such as... Figure 1 The diagram shows a flowchart of an anchorage monitoring method. This method can be executed by any electronic device, such as a terminal device, or by both a terminal device and a server. For ease of description, the method provided in this embodiment will be described below using a terminal device as the execution subject. Figure 1 The flowchart shown indicates that the method may include the following steps: Step S110: Determine the anchor position monitoring method according to the equipment status of the ship's positioning equipment. The anchor position monitoring method is either a first monitoring method or a second monitoring method. The first monitoring method is a monitoring method that uses the ship's location at the activation time as a reference point. The second monitoring method is a monitoring method that uses any tracking target that meets the set tracking conditions as a reference point. The activation time is the time when the anchor position monitoring function is activated. Step S120: According to the anchor position monitoring method, determine in real time the distance between the monitored target and the reference point, wherein the monitored target is the ship itself or other tracking targets; Step S130: Based on the distance value and the preset alarm threshold value, the monitoring of the monitored target is realized.

[0025] The method of the present invention allows for the flexible selection of either a first monitoring mode or a second monitoring mode as the anchor position monitoring mode, depending on the equipment status of the ship's positioning equipment. This enables the real-time determination of the distance between the monitored target and the reference point based on the anchor position monitoring mode, thereby achieving monitoring of the monitored target based on the distance value and a preset alarm threshold.

[0026] The following specific embodiments will further illustrate the solution of the present invention. First, the principles of the first monitoring mode (also known as GPS reference mode) and the second monitoring mode (also known as target reference mode) will be introduced. In the GPS reference mode, the location of the ship at the moment when the anchor monitoring function is activated (activation time) is used as the reference point. The monitoring mode determines whether the ship has deviated from the anchor position by judging the change in distance between the monitored target (the ship or other tracked target) and the reference point. In the target reference mode, any tracked target that has been stably tracked is used as the reference point. The distance value is the distance between the monitored target and the reference target (i.e., the reference point) at the activation time. If the distance between the monitored target and the reference target exceeds a set threshold during the anchor monitoring period, the ship is judged to have deviated from the anchor position.

[0027] The target reference mode ensures that anchorage monitoring can still be achieved even when the ship's positioning equipment (such as GPS) is unavailable, i.e., when the ship's position cannot be obtained. Under normal use, the first monitoring mode can generally be selected.

[0028] After introducing the principles of the two different monitoring methods, this application describes an anchorage monitoring method. In this embodiment, an anchorage monitoring method may include the following steps: Step S110: Determine the anchor position monitoring method according to the equipment status of the ship's positioning equipment. The anchor position monitoring method is either a first monitoring method or a second monitoring method. The first monitoring method is a monitoring method that uses the ship's location at the activation time as a reference point. The second monitoring method is a monitoring method that uses any tracking target that meets the set tracking conditions as a reference point. The activation time is the time when the anchor position monitoring function is activated. The aforementioned equipment status includes a first status where the ship's position is obtained through the positioning device and a second status where the ship's position cannot be obtained through the positioning device. Therefore, based on the equipment status of the ship's positioning device, the specific implementation method of the anchorage monitoring method is determined as follows: If the device status is the first status, then the first monitoring method is determined as the anchor monitoring method; If the device status is the second status, then the second monitoring method is determined as the anchor monitoring method.

[0029] The tracking conditions can be pre-set, such as a target that has been stably tracked. Stable tracking means that the position of the target can be monitored in real time and that the position has not deviated from the anchor position.

[0030] The anchor position monitoring function refers to radar navigation software with anchor position monitoring capabilities. The activation time refers to the activation time of the radar navigation software. After the radar navigation software is activated, the anchor position monitoring function in the radar navigation software can be used to monitor the monitored target.

[0031] Optionally, if the monitored target is the vessel itself, determining the anchorage monitoring method based on the equipment status of the vessel's positioning equipment includes: Based on the ship's navigation status and the equipment status, determine the anchorage monitoring method.

[0032] The navigation status of the ship can usually be reflected by the change in the ship's position. If the monitored target is the ship and the reference point is the ship or any tracking target that meets the set tracking conditions, in step S120, when determining the distance value between the monitored target and the reference point, the ship's position needs to be used in the calculation. Therefore, the anchor position monitoring method needs to be determined based on the ship's navigation status and equipment status.

[0033] Specifically, regardless of the ship's navigation status, when the equipment is in the first state, the first monitoring method can be determined as the anchorage monitoring method; when the equipment is in the second state, the second monitoring method can be determined as the anchorage monitoring method.

[0034] Optionally, if the monitored target is another tracking target, and the reference point is any tracking target that meets the set tracking conditions, the calculation of the distance value in step S120 does not require the position of the ship. In this case, when determining the anchor position monitoring method, the ship's navigation status can be disregarded, and the anchor position monitoring method can be determined directly based on the equipment status.

[0035] Optionally, different anchor monitoring methods can correspond to different alarm threshold values. Therefore, after determining the anchor monitoring method, the alarm threshold value (also known as the distance radius) corresponding to the anchor monitoring method can also be determined.

[0036] Step S120: According to the anchor position monitoring method, determine in real time the distance between the monitored target and the reference point, wherein the monitored target is the ship itself or other tracking targets; Where the monitored target is the ship itself, and the reference point is also the ship, the distance between the monitored target and the reference point can be the change in their positions at different times. For example, the distance between the ship's current position and its position at the activation time can be used as the distance between the monitored target and the reference point. It is understood that the current time and the activation time refer to two different times.

[0037] Before introducing the specific implementation of S120, we will first introduce the principle of how to calculate the distance between the monitored target and the reference point under different anchor monitoring methods and different monitored target conditions.

[0038] In GPS reference mode, the geographic coordinates of the anchor monitoring target (the monitored target) are recorded at the moment of activation, i.e., the position of the monitored target at the moment of activation. During the monitoring process, the relative relationship between the monitored target and the ship's position is calculated in real time based on the real-time detected position of the monitored target, i.e., the distance between the monitored target and the ship is calculated.

[0039] In target reference mode, assume A is the reference target (assuming it is stationary, it can also be called the reference point), O is the position of the ship at the activation time, B is the position of a certain target (denoted as target T, other tracked targets) at the activation time, O' is the position of the ship at a certain time after the activation time, and B' is the position of target T at a certain time after the activation time.

[0040] Based on the equipment measurements, the distance between the ship and the reference target at the activation time can be recorded as a1; the distance between the target T and the ship at the activation time can be recorded as b1; the distance between the reference target and the ship at a certain moment after the activation time can be recorded as a2; the distance between the target T and the ship at a certain moment after the activation time can be recorded as b2; the bearing of the reference target relative to true north at the activation time can be recorded as θ1; the bearing of the target T relative to true north at the activation time can be recorded as β1; the bearing of the reference target relative to true north at a certain moment after the activation time can be recorded as θ2; and the bearing of the target T relative to true north at a certain moment after the activation time can be recorded as β2. The above O, O', B, B', b1, a2, a1, b2, θ1, β1, θ2, and β2 are considered known information.

[0041] If the monitored target is the ship itself in target reference mode, the angle between the ship and the reference target at the current moment can be calculated based on known information. The ship's movement distance (the distance between the ship and the reference point) can be calculated based on this angle and known information. If this distance exceeds the preset alarm threshold, it indicates that the ship has deviated from the anchor position. If the monitored target is another tracking target, the distance between the monitored target and the reference target (reference point) at the activation time and the current moment are calculated respectively. Based on the calculation of the two distances and the two angles, the movement distance and direction of the monitored target can be obtained.

[0042] Based on the above principle, step S120, which determines the distance between the monitored target and the reference point in real time according to the anchor monitoring method, includes: If the anchorage monitoring method is the first monitoring method, and the monitored target is the ship itself, the ship's movement distance is calculated in real time based on the ship's position at the activation time and the ship's position at the current time, and the movement distance is used as the distance value between the monitored target and the reference point. If the anchorage monitoring method is the first monitoring method, and the monitored target is another tracking target, the distance between the other tracking target and the ship is calculated in real time based on the position of the other tracking target and the position of the ship at the same time. If the anchorage monitoring method is the second monitoring method, and the monitored target is the vessel itself, the distance between the vessel and the reference point is calculated in real time based on the vessel's position at the activation time, the reference point's position at the activation time, the vessel's position at the current time, and the reference point's position at the current time; the angle between the vessel and true north relative to the activation time is... According to the Law of Cosines, the calculation formula is as follows: ; in, This represents the distance traveled by the ship.

[0043] If the anchor monitoring method is the second monitoring method, and the monitored target is another tracking target, the distance between the other tracking target and the reference point is calculated in real time based on the position of the other tracking target at the activation time, the position of the reference point at the activation time, the position of the other tracking target at the current time, and the position of the reference point at the current time.

[0044] Calculation method: At the activation moment, the angle between the reference target and the monitored target is... At a certain moment, the angle between the reference target and the monitored target is... The distance AB between the reference target and the monitored target at the activation time and the distance at a certain time can be obtained using the law of cosines. .

[0045] After obtaining the distance, calculate the activation time and the angle ∠BAO between the ship, the monitored target, and the reference target at a certain time. The calculation formula is as follows: ; ; Finally, calculate the movement distance BB' of the monitored target, based on the above ∠BAO and The value is used to calculate the motion angle of the monitored target relative to the reference target. Finally, the value of BB' is calculated using the Law of Cosines. The formula is as follows: ; Optionally, the corresponding orientation can be considered during the distance calculation process to make the determined distance value more accurate.

[0046] Step S130: Based on the distance value and the preset alarm threshold value, the monitoring of the monitored target is realized.

[0047] Optionally, the above-mentioned monitoring of the monitored target based on the distance value and the preset alarm threshold includes: An alarm message is generated when the distance value exceeds the alarm threshold.

[0048] Specifically, when GPS reference mode is selected, the relative position of the monitored target to the ship's position is calculated in real time. The calculated distance value is compared in real time with a preset alarm threshold. When the distance value exceeds the alarm threshold, an alarm message is generated.

[0049] When the target reference mode is selected, if the monitored target is the ship itself, and the distance value exceeds the alarm threshold, it indicates that the ship has deviated from the anchor position and an alarm message is generated; if the monitored target is another tracking target, an alarm message is generated when the distance value exceeds the alarm threshold.

[0050] To better illustrate and understand the principle of the method provided by this invention, the following description uses an optional specific embodiment to illustrate the solution of this invention. It should be noted that the specific implementation of each step in this specific embodiment should not be construed as a limitation of the solution of this invention. Other implementations that can be conceived by those skilled in the art based on the principle of the solution provided by this invention should also be considered within the scope of protection of this invention.

[0051] See Figure 2 The flowchart shown illustrates that the anchorage monitoring method provided in this embodiment includes the following steps: S10, Confirm the anchor monitoring method. This step corresponds to the step S120 mentioned above. S20, based on the anchor position monitoring method, calculate the distance (distance value) during anchor position monitoring in real time and compare it with the alarm threshold distance (alarm threshold value); S30: Based on the real-time calculation results, determine whether to issue an alarm. Steps S20 and S30 correspond to the steps corresponding to S130 mentioned earlier.

[0052] The anchorage monitoring method described in this application allows users to flexibly select the appropriate anchorage monitoring method based on the vessel's motion status and the equipment's operating status.

[0053] Based on and Figure 1 Based on the same principle as the method shown, this embodiment of the invention also provides an anchorage monitoring device 20, such as... Figure 3 As shown, the anchor position monitoring device 20 may include an anchor position monitoring mode determination module 210, a distance value determination module 220, and a monitoring module 230, wherein: Anchorage monitoring mode determination module 210 is used to determine the anchorage monitoring mode according to the equipment status of the ship's positioning equipment. The anchorage monitoring mode is either a first monitoring mode or a second monitoring mode. The first monitoring mode is a monitoring mode that uses the ship's location at the activation time as a reference point. The second monitoring mode is a monitoring mode that uses any tracking target that meets the set tracking conditions as a reference point. The activation time is the time when the anchorage monitoring function is activated. The distance value determination module 220 is used to determine the distance value between the monitored target and the reference point in real time according to the anchor position monitoring method, wherein the monitored target is the ship or other tracking targets; The monitoring module 230 is used to monitor the target based on the distance value and the preset alarm threshold value.

[0054] Optionally, the aforementioned device status includes a first status where the position of the vessel is obtained through the positioning device and a second status where the position of the vessel cannot be obtained through the positioning device. When the anchorage monitoring method determination module 210 determines the anchorage monitoring method based on the device status of the vessel's positioning device, it is specifically used for: If the device status is the first status, then the first monitoring method is determined as the anchor monitoring method; If the device status is the second status, then the second monitoring method is determined as the anchor monitoring method.

[0055] Optionally, if the monitored target is the ship itself, the anchor position monitoring method determination module 210, when determining the anchor position monitoring method based on the equipment status of the ship's positioning equipment, is specifically used for: Based on the ship's navigation status and the equipment status, determine the anchorage monitoring method.

[0056] Optionally, when the distance value determination module 220 determines the distance between the monitored target and the reference point in real time according to the anchor monitoring method, it is specifically used for: If the anchorage monitoring method is the first monitoring method, and the monitored target is the ship itself, the ship's movement distance is calculated in real time based on the ship's position at the activation time and the ship's position at the current time, and the movement distance is used as the distance value between the monitored target and the reference point. If the anchorage monitoring method is the first monitoring method, and the monitored target is another tracking target, the distance between the other tracking target and the main ship is calculated in real time based on the position of the other tracking target and the position of the main ship at the same time. If the anchorage monitoring method is the second monitoring method, and the monitored target is the ship itself, the distance between the ship and the reference point is calculated in real time based on the ship's position at the activation time, the reference point's position at the activation time, the ship's position at the current time, and the reference point's position at the current time. If the anchor monitoring method is the second monitoring method, and the monitored target is another tracking target, the distance between the other tracking target and the reference point is calculated in real time based on the position of the other tracking target at the activation time, the position of the reference point at the activation time, the position of the other tracking target at the current time, and the position of the reference point at the current time.
