Description

Technical Field

[0001] The invention relates to the technical field of underwater flexible observation mirrors, and in particular to an underwater flexible observation mirror device and a control system thereof. Background Art

[0002] When natural disasters and accidents occur, rescue efforts must be taken immediately. For underwater natural disasters and accidents, people currently have very limited means and measures to take. Therefore, a device that can observe unknown underwater environments in real time is needed to obtain the situation at the scene of the dangerous situation in real time, so as to better formulate response plans. Since people's vision underwater is obstructed and visibility is poor, they cannot see the underwater situation through normal vision and cannot implement targeted rescue measures like on land. This requires the full use of high technology to solve the limited vision of the human eye and expand the field of vision. To this end, we propose an underwater flexible observation mirror device and its control system.

[0003] Patent CN213149371U discloses a controllable bending angle dual-light source flexible observation mirror device. By setting up the observation mirror and operating remote sensing, the interior of the building can be detected and observed through small gaps. It is suitable for operations in narrow and cluttered environments on land. However, when rescue or salvage operations are required underwater, water easily enters the shell of the observation mirror, and its joystick control probe direction design is not suitable for underwater control. For this reason, we propose an underwater flexible observation mirror device and its control system. Summary of the invention

[0007] As a preferred technical solution of the present invention, the fiber optic probe is connected to the first light source and the second light source through the first fiber optic light guide and the second fiber optic light guide. The fiber optic probe is composed of two light sources, visible light 550 and infrared light 940, which are alternately arranged in a uniform row along the outer circle of the endoscope probe.

The real-life images collected by the image acquisition module can be saved in the database of the underwater flexible observation mirror controller for subsequent playback. The videos and photos saved in the database of the underwater flexible observation mirror controller can be browsed on land through an external computer via USB. When used on land, it can be directly connected to an HDMI external display and transmitted to the smart terminal APP for real-time display via wireless, thereby facilitating the operator to make decisions and actions, and improving the convenience of the device.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0025] Example:

[0026] See also Figure 1-Figure 6 , an underwater flexible observation mirror device and its control system, including an underwater flexible observation mirror body 1, an aviation plug interface 7 and a stepper motor 13, the underwater flexible observation mirror body 1 is provided with an aviation plug interface 7 at the top, the underwater flexible observation mirror body 1 is provided with a connecting hose 3 at the top, and an endoscope probe 2 is provided at the top of the connecting hose 3, and a plurality of groups of optical fiber probes 12 are provided on the endoscope probe 2, two groups of stepper motors 13 are provided inside the underwater flexible observation mirror body 1, and a steel wire rope 4 is wound around the output end of the stepper motor 13, the top of the steel wire rope 4 is connected to the inner shell steel ring 9, and the endoscope probe 2 is installed inside the inner shell steel ring 9, the bottom end of the inner shell steel ring 9 is fitted with a bending joint snake bone 8, and the bending joint snake bone 8 is embedded in the connecting hose 3, the underwater flexible observation mirror body 1 is connected to a smart terminal, and a smart terminal window is installed on the smart terminal.

[0027] When the device needs to be used, the intelligent terminal is started to control the underwater flexible observation mirror body 1 through the wireless network, so that the underwater flexible observation mirror body 1 controls the stepping motor 13 to pull the corresponding steel wire rope 4, so that the steel wire rope 4 pulls the inner shell steel ring 9 to produce an angle change, and the inner shell steel ring 9 squeezes the bending joint snake bone 8. The bending joint snake bone 8 is elastically deformed due to the squeezing of the inner shell steel ring 9 and rotates in multiple directions, so that the inner shell steel ring 9 drives the endoscope probe 2 to adjust the angle and direction, and the direction and field of view of the endoscope probe 2 change. At the same time, the place and range of the image sensor collecting the real scene of the underwater environment in real time change, and then the first light source 5 or the second light source 6 is started, so that the first light source 5 or the second light source 6 respectively controls the optical fiber probe 12 to open through the first optical fiber light guide 10 and the second optical fiber light guide 11, so that the endoscope probe 2 can turn on the visible light 550 or the infrared light 940 for illumination according to the actual rescue environment and light while shooting and taking pictures underwater.

[0028] In other embodiments, a connecting hole 15 is provided at the bottom end of the underwater flexible observation mirror body 1;

[0029] When the underwater flexible observation mirror body 1 needs to be placed in an underwater environment for work, multiple sections of 5 to 30 meter long protection chains are connected to the underwater flexible observation mirror body 1 through the connecting holes 15. Multiple protection chains can be connected according to the needs of the rescue site. If necessary, the length can be continuously increased to meet the needs, but it cannot exceed the wireless communication coverage range. After the underwater operation is completed, the underwater flexible observation mirror body 1 can be retracted through the protection chain.

[0030] In other embodiments, the optical fiber probe 12 is connected to the first light source 5 and the second light source 6 through the first optical fiber light guide 10 and the second optical fiber light guide 11, and the optical fiber probe 12 is staggered with two light sources of visible light 550 and infrared light 940 and evenly arranged in a row along the outer circle of the endoscope probe 2;

[0031] Since the existing probe uses two light sources that use completely separate optical fiber light guides, the illumination on one side of the observation mirror probe is uneven. By arranging multiple groups of small optical fiber bundles evenly along the outer circle of the endoscope probe 2 according to the two light sources, the entire observation mirror probe can be illuminated evenly when the two light sources are illuminated.

[0032] In other embodiments, a central processing controller 17 and a sensor 14 are provided inside the underwater flexible observation mirror body 1, and the central processing controller 17 is integrated with a wireless communication module, a GPS, an image acquisition module, a database, a stepper motor control module, a visible light and infrared light illumination control module, a power supply module, a temperature, humidity and air pressure acquisition module, a USB interface, an RJ-45 interface and an HDMI interface;

[0033] Through this design, the central processing controller 17 controls the wireless signal generator 16 through the wireless communication module, and the wireless signal generator 16 is connected to the intelligent terminal through the wireless network system. The central processing controller 17 controls the endoscope probe 2 through the image acquisition module. The central processing controller 17 controls the stepper motor 13 through the stepper motor control module. The central processing controller 17 controls the optical fiber probe 12 through the visible light and infrared light illumination control module. The central processing controller 17 controls the sensor 14 through the acquisition module. The sensor 14 includes a temperature sensor, a humidity sensor and an air pressure sensor, so as to achieve the purpose of centralized processing of information through the central processing controller 17.

[0034] In other embodiments, the image data collected by the endoscopic probe 2 is transmitted to the wireless signal generator 16 via a wire, and the wireless signal generator 16 transmits the image data to the smart terminal via a wireless network system;

[0035] Through this design, the wireless signal generator 16 can adopt WIFI, 5G signals, etc., so that the smart terminal can connect and communicate with the underwater flexible observation mirror body 1 through the wireless network. When a wireless module is installed on the underwater flexible observation mirror body 1, it can also independently lay a network and adopt LoRa wireless communication technology.

[0036] In other embodiments, the underwater flexible observation mirror body 1, the endoscope probe 2 and the connecting hose 3 are all made of waterproof materials, and the RJ-45, USB and HDMI interfaces are provided with waterproof seals on the outside;

[0037] Since the RJ-45, USB, HDMI and other external interfaces on the underwater flexible observation mirror body 1 are not suitable for externally connecting related devices in water, when the underwater flexible observation mirror body 1 is working in water, the RJ-45, USB, and HDMI interfaces are protected by a waterproof sealing device.

[0038] In other embodiments, the intelligent terminal window consists of three parts: a video area, a menu area, and a status bar;

[0039] In the video area, you can view the video in real time, as well as play recorded videos and photos;

[0040] The menu area contains menus at all levels and shortcut buttons for the main menus. You can navigate through the menus to perform operations and set parameters. The menus can be hidden when browsing in full screen or playing videos.

[0041] The status bar displays the current underwater temperature, humidity and air pressure in real time, as well as GPS positioning data. If you are in water, the humidity will not be displayed.

[0042] In other embodiments, the menu area of ​​the intelligent terminal consists of four parts: video display preview playback, lighting, probe direction adjustment and parameter setting;

[0043] The video display preview playback can control the camera sensor to record videos and take photos of underwater places, and play back the videos and photos that have been taken;

[0044] Lighting can control the opening or closing of two light sources, visible light 550 and infrared 940, and provide lighting;

[0045] The probe direction adjustment can control the stepper motor to adjust the underwater probe up, down, left, and right, so as to observe the real scene from different angles and directions. It can also reset the probe to return to its original state.

[0046] Parameter setting can set parameters for the state of the endoscopic probe 2 .
