Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a navigation signal light shading control method and a navigation signal indication module. Background Art

[0002] The navigation lights of seagoing vessels are visual signals directly related to the safety of ships. They can identify the position and status of ships and notify their intention to sail at sea, thereby avoiding collisions. The navigation lights of seagoing vessels should not only be designed based on the International Regulations for Preventing Collisions at Sea, 1972, as amended (hereinafter referred to as the "Collision Regulations"), but also meet the special requirements of the navigation area and waterway management authorities. Among the various regulations, some navigation lights must meet the 360° all-round illumination requirements, such as the anchor lights, out-of-control lights, draft restriction lights and maneuverability restriction lights stipulated in the "Collision Regulations".

[0003] If the 360° all-around illumination requirement cannot be met (too much obstruction by surrounding obstacles), two sets of lights on the left and right sides of the mast 100 can be used to illuminate 180° outwards respectively to achieve 360° complementary all-around illumination. Figure 1 and Figure 2 As shown. To achieve 180° illumination on one side, a 180° sunshade needs to be installed on the inner side of the lamps on both sides to meet the regulatory requirements. However, the light sources on the left and right sides are not at the same point. Although the 180°+180° can meet the 360° all-round illumination requirement of the regulations, this complementary approach of light sources in different locations will naturally form a 200° blind spot in the field of vision, such as Figure 2 As shown, the shaded area is the theoretical blind area, and the sunshade cannot be adjusted once installed.

[0004] Therefore, it is urgent to provide a navigation signal light shading control method and a navigation signal indication module to solve the above problems. Summary of the invention

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] In order to adjust the angle of illumination according to actual use requirements, eliminate blind spots in the field of vision, and help ships navigate safely, this embodiment provides a navigation signal light visor control system. Figures 3 to 5 The specific contents of this embodiment are described in detail.

[0042] The present embodiment provides a navigation signal indication module, which is arranged on the light mast on the port side and the starboard side of the ship, and includes a shading assembly 1, a light emitter 2, a driving unit and an angle measuring unit. The shading assembly 1 includes a first arc-shaped shading plate 11 and a second arc-shaped shading plate 12 and a third arc-shaped shading plate 13 slidably arranged at both ends of the first arc-shaped shading plate 11. The first arc-shaped shading plate 11, the second arc-shaped shading plate 12 and the third arc-shaped shading plate 13 are arranged to form an arc-shaped shading area. The center angle of the first arc-shaped shading plate 11 is less than 180 degrees, and the first arc-shaped shading plate 11 is fixedly arranged on the light mast. The center angle A of the second arc-shaped shading plate 12 is less than 180 degrees, and the center angle B of the third arc-shaped shading plate 13 is less than 180 degrees. The light emitter 2 is arranged at the center of the first arc-shaped shading plate 11. The second arc-shaped shading plate 12 and the third arc-shaped shading plate 13 are respectively connected to the driving unit in a transmission manner, and the driving unit is used to drive the second arc-shaped shading plate 12 and the third arc-shaped shading plate 13 to move along the arc track. Exemplarily, the driving unit includes at least two servo motors, and the second arc-shaped shading plate 12 and the third arc-shaped shading plate 13 are respectively driven by different servo motors, thereby improving the automation degree of the navigation signal indication module. The angle measurement unit is used to detect the rotation angle of the second arc-shaped shading plate 12 and the third arc-shaped shading plate 13. The angle measurement unit can be, but is not limited to, a potentiometer disposed on the servo motor, and the rotation angle of the shading plate is measured by the potentiometer.

[0043] For example, the second curved sunshade 12 is located at one end of the first curved sunshade 11 close to the bow, and the second curved sunshade 12 is added to adjust the sunshade angle of the sunshade assembly 1 close to the bow. The third curved sunshade 13 is located at one end of the first curved sunshade 11 close to the stern, and the third curved sunshade 13 is used to adjust the sunshade angle of the sunshade assembly 1 close to the stern.

[0044] Understandably, if Figure 5As shown, the adjustable angle of the shading component 1 can be divided into two parts, front and rear, with the parallel hull direction as 0°, the front adjustable angle ±α, and the rear adjustable angle ±β. Generally speaking, the chimney is behind the navigation signal indicator (also called the all-round light), and the adjustable angle β range behind it is small. The maximum value B of the adjustable angle can be determined according to the specific project, that is, 2β≤B, mainly considering the adjustable angle α in front of the lamp. Due to the obstruction of the masts on both sides, the adjustable angle α is less than 90°. In actual projects, α will be smaller due to the obstruction of various obstacles. The maximum adjustable angle A needs to be determined according to the actual project, that is, 2α≤A<180°. After determining the front and rear limit angles A and B, the adjustment angle of the visible light in front of the lamp is ±α, and the adjustment angle of the visible light in the rear is ±β. That is to say, for a light source on one side, the visible angle range is a minimum of 180°-α-β and a maximum of 180°+α+β. Based on the above scheme, the shading component 1 can be set to be fixed and movable. The first arc-shaped light shielding plate 11 is a fixed part, and the second arc-shaped light shielding plate 12 and the third arc-shaped light shielding plate 13 are adjustable movable parts.

[0045] The present embodiment also provides a navigation signal light shading plate control method comprising the following steps: the control selection module enters the manual mode or the automatic mode; when entering the automatic mode, the blind spot angle adaptive auxiliary decision module transmits the first angle parameter and the second angle parameter to the blind spot angle control module, and the blind spot angle control module sends the execution angle adjustment command to the drive unit, and the drive unit drives the second curved shading plate 12 to rotate the first angle parameter and drives the third curved shading plate 13 to rotate the second angle parameter; when entering the manual mode, the manual operation knob is rotated to transmit the third angle parameter and the fourth angle parameter to the blind spot angle control module, and the blind spot angle control module sends the execution angle adjustment command to the drive unit, and the drive unit drives the second curved shading plate 12 to rotate the third angle parameter and drives the third curved shading plate 13 to rotate the fourth angle parameter. The navigation signal light shading control method not only has both manual and automatic modes, but also can adjust the angle of illumination according to actual use requirements, eliminate blind spots in the field of vision, and help ships to navigate safely.

[0046] Furthermore, the angle adjustment unit of the blind spot angle control module is preset with a first angle limit value and a second angle limit value, the first angle parameter and the third angle parameter are not greater than the first angle limit value, and the second angle parameter and the fourth angle parameter are not greater than the second angle limit value. By presetting the first angle limit value and the second angle limit value, the blind spot angle control module has a limit function, which limits the rotatable angle range of the second arc-shaped light shielding plate 12 and the third arc-shaped light shielding plate 13.

[0047] Furthermore, the blind spot angle adaptive auxiliary decision-making module is connected to the radar, electronic nautical chart, ship automatic identification system and ship CCTV system to provide real-time angle adjustment suggestions, assist decision-making, accurately locate nearby ships, and cooperate with intelligent algorithms to achieve blind spot adaptive avoidance.

[0048] Exemplarily, the blind spot angle adaptive auxiliary decision-making module uses the signals of the radar and ship CCTV system as input conditions for image recognition, calculates the heading of surrounding ships through the target detection algorithm, and then assists in decision-making for heading adjustment and avoidance based on the calculated heading of surrounding ships.

[0049] For example, based on the ship's own heading and avoidance priority, the blind spot angle adaptive auxiliary decision-making module gives real-time direction and angle parameters of the blind spot that should be avoided. On the one hand, it avoids ship collisions by changing the heading, and on the other hand, it eliminates or reduces the blind spot of vision by adjusting the sunshade, thereby avoiding ship collisions.

[0050] Furthermore, in the avoidance priority, the oncoming ship is marked as the first-level avoidance target, and the non-oncoming ship is marked as the second-level avoidance target. When there are oncoming ships and ships from other directions, the oncoming ship is prioritized as the first-level avoidance target to avoid head-on collisions of ships and reduce collision losses.

[0051] Furthermore, in the avoidance priority, the departing ship is marked as the third-level avoidance target. The departing ship is the least dangerous, so the lowest priority avoidance target is the departing ship.

[0052] Furthermore, the blind spot angle adaptive auxiliary decision-making module and the angle measurement unit are both electrically connected to the blind spot range comprehensive display module. The blind spot range comprehensive display module can comprehensively display the connected radar, electronic chart, ship automatic identification system and ship CCTV system, and additionally receive feedback of the measured angle to increase the display of the blind spot range.

[0053] Furthermore, the system abnormal alarm module is used to detect power failure, control system failure and angle input and feedback deviation in real time and alarm to ensure the stable operation of the system. The power drive module is used to provide stable power quality for the servo motor, angle measurement unit and main control unit.

[0054] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
