Description

TECHNICAL FIELD

[0001] The present application relates to the field of photoelectric tracking monitoring and laser communication technology, in particular to a tracking monitoring and laser communication integrated device. BACKGROUND

[0002] In recent decades, photoelectric tracking monitoring systems have been widely used in various fields such as industry and agriculture. The current advanced photoelectric tracking system usually has various sensors of different wavebands and types such as visible light, infrared, and laser range finder. The photoelectric tracking monitoring system has the characteristics of long-distance observation, target positioning and tracking, all-weather operation, and servo precise control, and is applied more and more widely. At present, the vehicle data transmission mode is to use the vehicle-mounted radio communication system or the ground mobile communication network for data transmission, which has a large dependence on the ground mobile network and the vehicle-mounted communication radio station. In field investigation and unpopulated area operation, there are a large number of local areas without mobile signal coverage, and communication cannot be carried out when data transmission is needed. CONTENT OF THE UTILITY MODEL

[0003] To solve the above technical problems, the present application provides a tracking monitoring and laser communication integrated device, which comprises a rotating platform, a control assembly, and a laser ranging communication module. The rotating platform comprises a base, an elevation support capable of rotating in the horizontal direction is arranged on the base, and an optical cabin capable of rotating in the vertical direction is arranged on the elevation support. The control assembly is installed in the rotating platform.

[0004] The laser ranging communication module is accommodated in the optical cabin, and the laser ranging communication module comprises a visible light imaging assembly, a laser ranging assembly, and a laser communication assembly with parallel optical axes. The visible light imaging assembly is used for tracking or monitoring a target, and the visible light imaging assembly is electrically connected with the control assembly. The laser ranging assembly is used for emitting a first ranging laser and receiving a second ranging laser, and the second ranging laser is a laser reflected by the target after the first ranging laser is irradiated on the target. The laser ranging assembly is electrically connected with the control assembly. The laser communication assembly is used for emitting a first communication laser and receiving a second communication laser emitted by the target, and the laser communication assembly is electrically connected with the control assembly.

[0005] The visible light imaging assembly transmits the received visible light signal to the control assembly, the control assembly identifies the monitored target according to an image recognition algorithm, and controls the pitching support and the optoelectronic cabin of the rotating platform to move, so that the visible light imaging assembly is always aimed at the target. Since the optical axis of the laser communication assembly is arranged in parallel with the optical axis of the visible light imaging assembly, the laser communication assembly can be aimed at the target at the same time as the visible light imaging assembly. When a laser communication link needs to be established, the laser communication assembly emits a predetermined first communication laser to the target, and after receiving the corresponding second communication laser returned by the target, the establishment of the bidirectional communication link is completed. When the distance of the target needs to be measured, the laser ranging assembly emits a first ranging laser to the target, and receives a second ranging laser returned by the target, and the distance of the target is determined by analyzing the difference between the first ranging laser and the second ranging laser.

[0006] In some embodiments, the laser ranging assembly comprises a first laser and a laser receiver, and the laser communication assembly comprises a second laser. The first laser is used to emit the first ranging laser, the second laser is used to emit the first communication laser, and the laser receiver is used to receive the second ranging laser and the second communication laser.

[0007] The wavelength of the laser that can be received by the laser receiver is related to the material of the semiconductor device in the laser receiver, so the same laser receiver can only receive laser of a specific wavelength band. When the wavelength bands of the second ranging laser and the second communication laser are quite different, different laser receivers need to be used for receiving respectively, and when the wavelength bands of the second ranging laser and the second communication laser are similar, the same laser receiver can be used to receive the communication laser and the ranging laser, thereby simplifying the optical path, reducing the complexity of the device, and reducing the cost.

[0008] In some embodiments, the first laser and the second laser are both solid-state pulse lasers. Compared with gas pulse lasers, solid-state pulse lasers have the advantages of small size and high output power.

[0009] In some embodiments, the visible light imaging assembly comprises a camera, which can be a fixed-focus camera or a continuous zoom integrated camera. Preferably, the continuous zoom integrated camera is a commonly used camera in optoelectronic communication devices, which has high integration, is easy to install, has clear imaging, and can shoot targets at a long distance.

[0011] In some embodiments, the tracking, monitoring and laser communication integrated device further comprises a wireless communication component electrically connected to the control component, the wireless communication component being used for wireless communication. When the target is monitored by the visible light imaging component or the infrared imaging component, the wireless communication with other targets can also be performed.

[0012] In some embodiments, the tracking, monitoring and laser communication integrated device further comprises a console electrically connected to the control component and a display electrically connected to the control component. The console and the display cooperate to facilitate the operator to control the operation of each component.

[0013] In some embodiments, the working waveband of the laser ranging component and the laser communication component is 964-1164 nm. The laser in this waveband has strong penetration and small loss in the atmosphere.

[0014] The tracking, monitoring and laser communication integrated device provided by the application comprises a turntable, a control component and a laser ranging and communication module. The turntable comprises a base, the base is provided with a tilting support which can rotate in the horizontal direction, and the tilting support is provided with an optical cabin which can rotate in the vertical direction. The control component is installed in the turntable, and the laser ranging and communication module is accommodated in the optical cabin.

[0019] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other alternative embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0020] The first embodiment of the present application provides a tracking and monitoring and laser communication integrated device, as shown in the figure, comprising a rotating platform 1, a control assembly 2 and a laser ranging and communication module. The rotating platform 1 comprises a base 11, the base 11 is provided with a tilting support 12 which can rotate in the horizontal direction, and the tilting support 12 is provided with an optical cabin 13 which can rotate in the vertical direction. The horizontal direction rotation refers to the rotation around the axis d1 which is perpendicular to the horizontal plane, and the vertical direction rotation refers to the rotation around the axis d2 which is parallel to the horizontal plane. Figure 1

[0021] The control assembly 2 is installed in the rotating platform 1. The laser ranging and communication module is accommodated in the optical cabin 13, and the laser ranging and communication module comprises a visible light imaging assembly 31, a laser ranging assembly 32 and a laser communication assembly 33, the optical axes of which are parallel to each other. The visible light imaging assembly 31 is used for tracking or monitoring the target, and the visible light imaging assembly 31 is electrically connected with the control assembly 2; the laser ranging assembly 32 is used for emitting first ranging laser and receiving second ranging laser, the second ranging laser being the laser reflected after the first ranging laser irradiating the target, and the laser ranging assembly 32 is electrically connected with the control assembly 2. The laser communication assembly 33 is used for emitting first communication laser and receiving second communication laser emitted by the target, and the laser communication assembly 33 is electrically connected with the control assembly 2.

[0022] The tracking and monitoring and laser communication integrated device can be installed on a mobile carrier such as a vehicle, an airplane or a ship, or on a fixed building such as a building or a steel structure, and the tracked and monitored target can be a person, a vehicle, an airplane or a ship. The tracking and monitoring and laser communication integrated device provided by the present application can work in a surveillance and monitoring mode or in a laser communication mode.

[0023] When working in the surveillance and monitoring mode, for example, when tracking and monitoring a vehicle, when the vehicle enters the field of view of the visible light imaging assembly 31 or the operator aims the visible light imaging assembly 31 at the monitored vehicle through the control assembly 2, the visible light imaging assembly 31 will transmit the received visible light signal to the control assembly 2, the control assembly 2 identifies the monitored vehicle according to the image recognition algorithm, and controls the tilting support 12 and the optical cabin 13 of the rotating platform 1 to move, so that the visible light imaging assembly 31 can always aim at the monitored vehicle when the monitored vehicle moves, thereby realizing the tracking and monitoring of the moving vehicle.

[0024] ​When working in the laser communication mode, there are multiple ways to establish a communication link with the target, i.e. the active communication request from the side or the communication request from the target. There are multiple ways to make a communication request, such as the appointment of a fixed time, the display of a predetermined marker to the target or the emission of a predetermined laser signal. For example, the target makes a communication request by displaying a predetermined marker to the side, when the predetermined marker enters the field of view of the visible light imaging assembly 31, the visible light imaging assembly 31 automatically aligns the target under the cooperation of the control assembly 2 and the turntable 1, and since the laser communication assembly 33 is arranged in parallel with the optical axis of the visible light imaging assembly 31, the laser communication assembly 33 can simultaneously align the target. The target is also provided with the tracking and monitoring and laser communication integrated device provided in the present application, the laser communication assembly 33 emits a predetermined first communication laser to the target, and the target returns a predetermined second communication laser after receiving the first communication laser, and the laser communication assembly 33 receives the second communication laser, and the control assembly 2 decodes it to complete the establishment of a bidirectional communication link. Subsequently, the tracking and monitoring and laser communication integrated device can use the visible light imaging assembly 31 to keep the laser communication assembly 33 aligned with the target, or determine the relative position of each other by transmitting laser beacons between the laser communication assembly 33 and the target, so that the laser communication assembly 33 keeps aligned with the target. When it is necessary to measure the distance of the target, the laser ranging assembly 32 emits a first ranging laser to the target and receives a second ranging laser returned by the target, and by analyzing the difference between the first ranging laser and the second ranging laser, the distance between the target and the tracking and monitoring and laser communication integrated device is determined.

[0025] In the first embodiment, as shown in Figure 2 The laser ranging assembly 32 includes a first laser 321 and a laser receiver 322, and the laser communication assembly 33 includes a second laser 331. The first laser 321 is used to emit a first ranging laser, the second laser 331 is used to emit a first communication laser, and the laser receiver 322 is used to receive a second ranging laser and a second communication laser.

[0026] The wavelength of the laser that can be received by the laser receiver is related to the material of the semiconductor device in the laser receiver, so the same laser receiver can only receive a specific wavelength band of laser. When the wavelength bands of the second ranging laser and the second communication laser are different, different laser receivers need to be used to receive them respectively, and when the wavelength bands of the second ranging laser and the second communication laser are similar, the same laser receiver can be used to receive the communication laser and the ranging laser, thereby simplifying the optical path, reducing the complexity of the device and reducing the cost.

[0027] In the first embodiment, a solid-state pulsed laser is preferably used. Lasers can be classified into gas lasers and solid-state lasers according to their laser generation principle, and into continuous-wave lasers and pulsed lasers according to their emission method. In practical applications, solid-state lasers have the advantages of small size and high output power. Solid-state pulsed lasers are a commonly used type of laser for laser ranging.

[0028] In the first embodiment, as Figure 2 As shown, the visible light imaging component 31 includes a camera 311, which can be either a fixed-focus camera or a continuous zoom integrated camera. Preferably, a continuous zoom integrated camera is a type of camera commonly used in optoelectronic communication equipment, which has high integration, is easy to install, produces clear images, and can capture targets at a relatively long distance.

[0029] As a further improvement, such as Figure 3 As shown, in the second embodiment of this application, the laser ranging communication module further includes an infrared imaging component 34 for tracking or monitoring the target. The optical axis of the infrared imaging component 34 is parallel to the optical axis of the visible light imaging component 31. The infrared imaging component 34 includes an imaging unit 341. Infrared cameras are classified into fixed-focus infrared cameras and zoom infrared cameras according to whether they are zoomed, and into cooled infrared cameras and uncooled infrared cameras according to whether they are cooled. Preferably, the imaging unit 341 adopts a cooled fixed-focus infrared camera, which has high resolution and can capture images of distant targets at night, enabling all-weather tracking and monitoring of targets.

[0030] In the second embodiment of this application, as Figure 3 As shown, the integrated tracking, monitoring, and laser communication device also includes a wireless communication component 4, which is electrically connected to the control component 2 and is used for wireless communication. When monitoring a target using the visible light imaging component 31 or the infrared imaging component 34, it can also communicate wirelessly with other targets.

[0031] In the second embodiment of this application, as Figure 3 As shown, the integrated tracking, monitoring, and laser communication device also includes a control console 5 and a display 6. The control console 5 is electrically connected to the control component 2, and the display 6 is electrically connected to the control component 2. The control console 5 and the display 6 work together to facilitate operator control of the operation of each component. The control console 5 and the display 6 can be installed on the same vehicle as the integrated tracking, monitoring, and laser communication device, such as a vehicle, aircraft, or ship, or they can be installed separately in a ground building and communicate wirelessly with the control component 2 via the wireless communication component 4 for remote control operation.

[0032] Preferably, both the laser ranging component 32 and the laser communication component 33 operate in the 964–1164 nm wavelength range. Lasers in this wavelength range have strong penetrating power and low loss when propagating through the atmosphere.

[0033] The laser ranging assembly 32 in the present application can not only be used for ranging, but also can continuously irradiate a target. When laser guidance is needed, for example, when a position of a target needs to be identified in a field activity, a predetermined laser signal can be used to continuously irradiate the target. Other laser devices can find the target after receiving the laser signal reflected by the target, so as to determine the position of the target.

[0034] Finally, it should be noted that if the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings). If the certain posture changes, the directional indications will also change accordingly.

[0035] In addition, if the present application involves descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the scope of protection claimed by the present application.

[0036] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
