Unless otherwise indicated, all the technical and scientific terms used in this paper have the same meaning as that understood by the ordinary skilled person in the technical field to which the utility model belongs.

[0025] It should be noted that the terms used here are only for describing the specific embodiments, and are not intended to limit the exemplary embodiments according to the utility model.

[0026] Embodiment one

[0027] As Figure 1 Indicated, the wind farm display system includes: monitoring module, laser projection module, control module, optical signal receiving module, processing module, display module, brightness adjustment module.

[0028] The monitoring module is connected with the control module, and is used for monitoring the target ship in real time, and sending the target ship information to the control module;The laser projection module is connected with the control module and the processing module respectively, receives the instruction sent by the control module, projects laser to the surface of the target ship, and transmits the indicating cursor to the display module for display through the processing module;The optical signal receiving module is connected with the processing module and the control module respectively, receives the returned target ship image digital signal, and transmits to the processing module for processing;The display module is connected with the processing module, and includes image display screen and indicating cursor display screen, and is used for displaying the target ship image information and laser indicating cursor respectively after processing;The brightness adjustment module is connected at the signal output end of the control module, and adjusts the brightness data of the display screen.

[0029] In the embodiment, the hardware device of the monitoring module includes an AIS device and a distance sensor, which automatically identifies and monitors the distant ship in real time; the laser projection module is used for emitting laser and projecting a laser indication point on the surface of the target ship, and includes a laser pointer and a laser beam expansion lens. The indication point of the laser pointer is visible, and the laser beam expansion lens can collimate and shape the outgoing light of the laser pointer, so that the divergence angle of the emitted light beam is smaller, and the quality of the emitted light indication point is approximately flat light, which can be calibrated with the indication cursor on the display screen; the control module includes a controller; and the processing module includes a central processing unit and an image signal processor.

[0030] The optical signal receiving module includes an optical lens, a filter, and a gated image intensifier, and directly transmits a digital image signal. Specifically,

[0031] The optical lens collects the reflected and scattered light signals after the light beam emitted from the laser beam expansion lens irradiates on the surface of the target ship; the filter is a narrow-band filter corresponding to the wavelength of the laser emitted by the laser pointer, and the purpose is to filter out the stray signals in the returned light signals collected by the optical lens. After filtering, the returned light signals enter the gated image intensifier. The target image signal obtained by the gated image intensifier is collected by the image signal processor of the processing module and is subjected to denoising processing, and then the digital signal is sent to the central processing unit of the processing module. The central processing unit further enhances the received digital signal, and displays the image on the display screen of the display module.

[0032] The laser projection module and the optical signal receiving module are connected to the processing module, and the laser indication cursor and the image digital signal of the target ship are both transmitted to the processing module. The processing module is connected to the display module and the control module, and is used for transmitting the laser indication cursor and the processed target ship image information to the display module for display.

[0033] In the embodiment, the monitoring module further includes a serial port, a UDP, and a server. When the AIS device automatically identifies a ship close to the wind farm area, the controller receives the AIS device information through the RS-232 serial port / RJ-45 network port and decodes it, and the server extracts and analyzes it. Considering the real-time nature of information transmission and a series of advantages of the UDP protocol such as no connection, high speed, and less resource occupation, the UDP protocol is used for information transmission. However, UDP has the problem of packet loss, which cannot guarantee the correctness of the transmitted information. Therefore, a check code is added to the tail of the UDP data for transmission information verification.

[0034] After the controller receives the monitoring information, the controller controls the laser pointer to emit laser and project a laser indication point on the surface of the target object, and the distance sensor detects the distance and sends it to the controller. The controller obtains the distance between the laser indication point and the display system through the distance sensor, so as to realize accurate positioning.

[0035] The brightness adjusting module comprises a light sensor, which is connected in communication with the control module and the processing module, and is used for detecting and generating brightness data of the display screen and transmitting the brightness data to the control module.

[0036] In the embodiment, the display screen is divided into n equal-area blocks, wherein n is greater than or equal to 1 and is a positive integer.

[0037] The controller receives n pieces of brightness data L , , …, of different blocks through the light sensor, takes the maximum value of the n pieces of brightness data as a standard value , and takes the difference between the remaining brightness data L and the standard value as a difference value. If the difference value is greater than a preset difference threshold value, the corresponding light intensity is adjusted through the brightness adjusting module until the brightness data is the same. In the case of bad weather, the overall brightness of the display screen can be automatically increased to ensure the visual effect.

[0038] In the embodiment, the image display screen and the indicating cursor display screen are liquid crystal display screens, and the optical lens is a long-focus lens.

[0039] Although the specific embodiments of the utility model have been described in combination with the drawings, the description is not a limitation on the protection scope of the utility model. Those skilled in the art should understand that various modifications or changes made on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
