Description

Technical Field

[0001] The invention relates to a cab adaptive lighting system, belonging to the technical field of ship lighting control. Background Art

[0002] When a ship is sailing and another ship is approaching, if the user fails to find out in time, it is easy to cause a safety accident and irreparable losses. The traditional way to avoid collisions is for the personnel in the cab to use telescopes and other equipment to observe and remind the driver to make avoidance operations in time when there is a risk of collision. This requires the observer to concentrate highly and there are certain safety hazards.

[0003] In response to this type of situation, the art urgently needs a reminder system that can automatically sense the dynamics of a ship when it approaches and reflect it to the user in a physical form that is easily perceived by the human body, while being adaptable to various ships and eliminating the potential safety hazards of ship navigation collisions. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cab adaptive lighting system, which automatically controls the flashing of the cab lights to alert users when a ship approaches, thereby solving potential ship collision safety issues.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] The present invention provides an adaptive lighting system for a driving cab, comprising a ship identification system, which is arranged on the hull and used for monitoring various operation data information of ships around the currently driven ship; a driving cab lighting system, which is arranged on the top wall of the ship's driving cab and used for lighting and collision emergency feedback; and a control module, which is used for receiving the operation data information of surrounding ships collected by the ship identification system and converting it into a control signal and transmitting it to the driving cab lighting system to make the collision emergency feedback.

[0007] Preferably, the ship identification system includes an AIS automatic identification system and a radar system, both of which are connected to the control module signal, and the radar system is an S-band and X-band radar.

[0008] Furthermore, the various operating data information of the surrounding ships include location information, trajectory information, speed information and ship size information.

[0009] Furthermore, the cab lighting system includes a plurality of cab lights, and the plurality of cab lights are evenly spaced according to the shape of the cab, and one third of the cab lights are emergency lighting lights.

[0010] Furthermore, the collision emergency feedback of the cab lighting system includes flashing of the cab lights.

[0011] Furthermore, the control module includes an MCU module, a demodulation module, a data storage module, a radar interface module and an AIS interface module. The demodulation module is electrically connected to the AIS automatic identification system through the AIS interface module, and is used to convert the ship information acquired by the AIS automatic identification system into a digital signal; the demodulation module is electrically connected to the radar system through the radar interface module, and is used to convert the radar signal into a digital signal; the demodulation module is electrically connected to the MCU module, and is used to verify the digital signal to control the flashing rhythm of the cab light, and the data storage module is electrically connected to the MCU module for storing MCU module data.

[0012] Furthermore, the cab light is connected to the MCU module via a ZigBee module signal.

[0013] Furthermore, the control module is electrically connected to a watchdog module for monitoring the operation of the control module and ensuring the process operation of the system.

[0014] Furthermore, the flashing rhythm of the cab lights includes strong flashing and weak flashing. When the surrounding ships are within the first preset range of the currently driven ship, the cab lights of the currently driven ship perform strong flashing; when the surrounding ships are within the second preset range of the currently driven ship, the cab lights of the currently driven ship perform weak flashing.

[0015] Furthermore, the first preset range includes surrounding ships within a 1.5-kilometer range around the currently driven ship, and the second preset range includes surrounding ships within a 1.5-kilometer to 3-kilometer range around the currently driven ship.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1 and Figure 2 The present application provides a cab adaptive lighting system, including a ship identification system, a cab light 2 light system and a control module. The ship identification system is installed on the hull to monitor various operating data information of ships around the current ship. The cab light 2 light system is arranged on the top wall of the ship's cab 1 for lighting and collision emergency feedback. The control module is installed in the ship's cab 1 to receive the surrounding ship operating data information collected by the ship identification system and convert it into a control signal to transmit to the cab light 2 light system to make a collision emergency feedback, so as to promptly remind the user when a ship approaches to eliminate collision safety hazards.

[0028] The ship identification system includes an AIS automatic identification system 3 and a radar system 4, both of which are connected to the control module signal. Specifically, the AIS automatic identification system 3 is used to obtain ship information within a certain range of the current driving ship; the radar system 4 is an S-band and X-band radar, which is used to autonomously detect the position, trajectory, speed of the target ship, judge and analyze the size of the target ship and other information, and transmit it to the control module for further processing. When the AIS automatic identification system 3 is used alone, it is impossible to identify the ship information that is not turned on or installed. Therefore, it is necessary to use the radar system 4 and the AIS automatic identification system 3 at the same time to obtain the surrounding ship information to ensure the comprehensiveness of the ship identification system. In this embodiment, the use and detection principles of the AIS automatic identification system 3 and the radar system 4 are all existing technologies and will not be described in detail.

[0029] Reference Figure 1 and Figure 2 The cab light 2 light system includes a plurality of cab lights 2, which are LED lights. The plurality of cab lights 2 are evenly arranged according to the shape of the ship's cab 1 to meet the illumination requirements of the cab. In this embodiment, the cab lights 2 are preferably 2×8W LED ceiling lights, and the spacing between the adjacent cab lights 2 in the front, back, left and right directions is preferably two meters, and one-third of the cab lights 2 are used as emergency lighting lamps. The collision emergency feedback of the cab light 2 light system is in the form of flashing cab lights 2.

[0030] Reference Figure 1-Figure 3 The control module includes an MCU module 5, a demodulation module 6, a data storage module 7, a radar interface module 8 and an AIS interface module 9. The demodulation module 6 is electrically connected to the AIS automatic identification system 3 through the AIS interface module 9, and is used to convert the ship information obtained by the AIS automatic identification system 3 into a digital signal; the demodulation module 6 is electrically connected to the radar system 4 through the radar interface module 8, and is used to convert the radar signal into a digital signal; the demodulation module 6 is electrically connected to the MCU module 5, and then the digital signal converted by the demodulation module 6 is verified by the MCU module 5 to automatically control the flashing rhythm of the cab light 2. The data storage module 7 is electrically connected to the MCU module 5 for storing various data of the MCU module 5 to prevent data loss. In a feasible embodiment, the MCU module 5 can also be replaced by other control units that can be connected to each module and realize processing control, such as a PLC control unit. In this embodiment, the demodulation processing of the demodulation module 6, and the use of the data storage module 7, the radar interface module 8 and the AIS interface module 9 are all existing technologies and will not be described in detail.

[0031] Furthermore, several cab lights 2 are connected to the MCU module 5 through the ZigBee module 10 signal, and then the control signal output by the MCU module 5 is sent to the cab lights 2 to realize the control of the flashing state of the cab lights 2. In a feasible embodiment, other wireless communication technologies such as WIFI, Bluetooth, etc. can also be used. Compared with WiFi and Bluetooth technologies, ZigBee wireless communication technology has great advantages in battery life, maximum network nodes and networking time, and has higher reliability and response speed, which can meet the use requirements in the cab.

[0032] The flashing rhythm of the cab light 2 includes strong flashing and weak flashing. The MCU module 5 is preset with a first preset range and a second preset range for controlling the flashing state of the cab light 2. When the surrounding ships are within the first preset range of the currently driven ship, the cab light 2 of the currently driven ship performs strong flashing; when the surrounding ships are within the second preset range of the currently driven ship, the cab light 2 of the currently driven ship performs weak flashing. The first preset range and the second preset range are adjusted and adapted according to the ship conditions and the equipment response speed. In this embodiment, the first preset range is preferably that the surrounding ships are within 1.5 kilometers around the currently driven ship, and the second preset range is preferably that the surrounding ships are within 1.5 kilometers to 3 kilometers around the currently driven ship.

[0033] During ship navigation monitoring, the MCU module 5 simultaneously receives signals from the AIS automatic identification system 3 and the radar system 4. The MCU module 5 first determines whether there is a ship within 1.5 km. If there is a ship, it turns on strong flashing, and stops flashing when it leaves. If not, it then determines whether there is a ship within 3 km. If there is a ship, it turns on weak flashing until it leaves and stops flashing. When it is determined that there is no ship within 3 km, the cab light 2 remains in a normal state and does not flash.

[0034] Reference Figure 2 The control module is also electrically connected to a watchdog module 11 for monitoring the operation of the control module. When the control module freezes, it can automatically reset it to ensure the operation of the system process.

[0035] The above is only a preferred embodiment of the present invention, and is not any formal or substantial limitation of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be regarded as the protection scope of the present invention. Any technician familiar with this profession, without departing from the spirit and scope of the present invention, can make some changes, modifications and equivalent changes made by using the technical content disclosed above, which are equivalent embodiments of the present invention; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the present invention are still within the scope of the technical solution of the present invention.
