Description

Technical Field

[0001] This invention belongs to the field of optoelectronic control device design, and particularly relates to a fish optoelectronic combined control device and its usage method. Background Technology

[0002] Photoelectric and electromagnetic biocontrol technology utilizes optical, electrical, and magnetic signals to control bio-hybrid robots. It has broad application prospects in areas such as area search, disaster management, and agricultural production. Fish-based biocontrol devices achieve biocontrol by mounting a device on the fish's head and emitting light stimulation signals to the fish's eyes, or projecting electrical or magnetic stimulation signals onto its head. These mounting devices are mainly installed in two ways: one is a head-mounted installation method, such as CN201911048995.8 "A light stimulation mounting device and method for motion control of a carp robot." This type of installation method results in a large device structure. This method not only obstructs the fish's original field of vision but also significantly hinders their movement and feeding behavior. Another approach is through fixed installation, as described in CN202011484913.7, "A Rotatable Light Source Light Stimulation Mounting Device and Method Thereof." This structure has less impact on fish, but it requires a complex switching mechanism to achieve light stimulation, resulting in a large volume and weight on both sides of the device. Furthermore, the light source is far from the fish's eyes, leading to significant energy dissipation of the light stimulation signal and making precise input impossible. Independent output and control of the light signals on both sides necessitate a dedicated synchronization system. Therefore, the overall structure and functionality are too complex for industrial applications. Summary of the Invention

Detailed Implementation

[0032] The present invention will be described in detail below with reference to specific embodiments.

[0033] This invention provides a smaller, simpler, more efficient, and lower-energy-consumption photoelectric electromagnetic joint control device for fish. By optimizing the light control structure and reducing the frequency of light control LED usage, energy consumption is reduced while ensuring that the light signal can reach both eyes synchronously. It supports various photoelectric electromagnetic control output modes, such as binocular synchronous light signal mode, monocular asynchronous light signal, and dual-sided synchronous or single-sided asynchronous electromagnetic signal. The device adopts a fully enclosed structure with no internal moving parts, featuring low energy consumption, small size, and silent and vibration-free operation. It can minimize adverse effects on the test object. At the same time, the device does not affect the normal line of sight of the object when not in use. When not actively controlled, it can minimize interference with the target's autonomous movement behavior, which is conducive to further research on autonomous movement combined with active behavior control.

[0034] like Figure 1 As shown, Figure 2 As shown, the core structure of the fish photoelectric electromagnetic combined control device of the present invention includes a mounting box 1, an electrode assembly 2, a light guide assembly 3, and an electromagnetic assembly 4.

[0035] The mounting box is used to protect the internal optoelectronic components, provide a watertight environment, and ensure that the device can be stably connected to the target head.

[0036] The mounting box 1 is a hollow arc-shaped box with a mounting platform 10 on its top. The top of the mounting platform 10 has an opening, and a cover plate 6 is provided at the opening.

[0037] The mounting box 1 is provided with two isolation ribs 11 arranged parallel to each other in the left and right direction. The two isolation ribs 11 divide the inner cavity of the mounting box 1 into a light guide cavity 1b in the middle and mounting cavities 1c located on the front and rear sides of the light guide cavity 1b. The bottom of the light guide cavity 1b is provided with a light passage hole 1a, and a light transmission lens 50 is embedded in the bottom opening of the light passage hole 1a. The top opening of the mounting cavity 1c is provided with a set of electrode mounting holes 1f arranged symmetrically in the left and right direction and fixing holes 1d located on both sides of the electrode mounting holes 1f.

[0038] A fixing bolt is provided in the fixing hole 1d. During the installation of the device, a hole is drilled in the frontal bone area of ​​the head of the object to connect the device. During the drilling process, the brain's supplementary function area should be avoided and appropriate protective measures should be taken.

[0039] To ensure structural water tightness and integrity while reducing structural weight, the mounting box 1 is preferably manufactured using 3D printing technology.

[0040] In this application, an independent and symmetrical light guide cavity and a front-to-back and left-to-right symmetrical mounting cavity combination structure are adopted. The independent light guide cavity ensures the stability of the output of the internal light stimulation output device and avoids interference from other components. The mounting cavities on both sides provide sufficient installation space, which facilitates the installation and fixation of supporting power supply, control board and other structures. The overall structure is omnidirectionally symmetrical and centrally distributed, which is conducive to the installation and use of the structure.

[0041] The electrode assembly is used to provide electrical stimulation signals, the light guide assembly is used to provide light stimulation signals, and the electromagnetic assembly is used to provide magnetic stimulation signals.

[0042] The electrode assembly 2 includes: a circuit mounting plate 20 disposed inside the mounting platform 10, two sets of electrode pins 21 located on the front and rear sides of the circuit mounting plate 20 and respectively facing the two sets of electrode mounting holes 1f, and a first LED lamp bead group 22 located at the bottom of the circuit mounting plate 20.

[0043] The light guide assembly 3 includes: installed in the light guide cavity 1b A light guide plate 30 in the shape of a dome, and second LED lamp bead groups 31 located at both ends of the light guide plate 30;

[0044] The light guide plate 30 has an arc-shaped structure. The top of the light guide plate 30 is provided with a main light-receiving platform 30a, and the two ends of the light guide plate 30 are provided with auxiliary light-receiving platforms 30b. The bottom of the auxiliary light-receiving platform 30b is directly opposite to the light-passing hole 1a. The main light-receiving platform 30a is located directly below the first LED lamp bead group 22, and the second LED lamp bead group 31 is located directly above the auxiliary light-receiving platform 30b.

[0045] Traditional light stimulation signal triggering methods involve setting up independent light stimulation structures in the visible areas on both sides of the target, and switching the light source through a rotating mechanism. This results in independent installation structures on both sides, independent control of the light stimulation output on both sides, and the need for additional electrical synchronization control structures when synchronization is required. Furthermore, this makes the installation structure more complex and bulky, consumes more energy, and has a greater impact on the target. In this application, a dual-LED group control mode is proposed based on actual needs.

[0046] The first LED bead group 22 serves as the main bead group to provide synchronous light stimulation signals to both eyes. The light stimulation signals reach both eyes synchronously through the light guide plate. Since the light signals originate from the same light source, the consistency and synchronicity of the signals are effectively guaranteed. The pure physical synchronization method does not require a complex circuit control structure, resulting in lower cost, simpler structure, and effectively reduced energy consumption for signal generation and the amount of control resources required.

[0047] As a light guiding material, the light guide plate is often used in the backlight assembly of liquid crystal displays as a light path guiding and control material. In this application, it is used to guide the emitted light of the first LED lamp bead group 22 to both sides, and then emit it through the light through hole 1a, and project it to the target eye through the light transmission lens 50 embedded in the bottom opening to achieve light stimulation output.

[0048] To improve signal effectiveness and prevent signal energy dissipation, in this embodiment, the light guide plate 30 is made of a special transparent PMMA material, and the surface of the light guide plate 30, except for the top surface of the main light-receiving platform 30a and the upper and lower end surfaces of the auxiliary light-receiving platform 30b, is coated with a reflective coating.

[0049] Alternatively, a reflective coating can be applied to the inner wall of the light guide cavity 1b to reflect the light signal overflowing from the light guide plate, thereby reducing signal energy loss during propagation.

[0050] The electromagnetic component 4 includes electromagnets 40 symmetrically arranged in the light guide cavity 1b or the mounting cavity 1c. The electromagnetic component forms a complete magnetic field around the target brain through the electromagnets on both sides, and the direction, intensity and other parameters of the magnetic field are controlled by the electromagnets to complete the output of electromagnetic stimulation signals.

[0051] To further simplify the structural design and facilitate assembly and use, this embodiment also includes an auxiliary lamp mounting base 51 for assembling the second LED bead group 31 and the electromagnetic components.

[0052] like Figure 2 , Figure 3 As shown, the auxiliary lamp mounting base 51 is fixedly installed in the light guide cavity 1b and located directly above the auxiliary light-receiving platform 30b. The second LED lamp bead group 31 is installed at the bottom of the auxiliary lamp mounting base 51, and the electromagnet 40 is installed on the upper side of the auxiliary lamp mounting base 51.

[0053] The top of the auxiliary lamp mounting base 51 is provided with an electromagnetic mounting plate surface 51a, and the electromagnet 40 is mounted on the electromagnetic mounting plate surface 51a.

[0054] The above structure is simple and convenient, facilitating integrated processing and manufacturing as well as rapid assembly. Its symmetrical installation and the installation structure with the longest span ensure the balance of mass on both sides of the device, improving the stability of the device. At the same time, it ensures that the electromagnet can provide a sufficiently large magnetic field control area, ensuring effective control of the magnetic field parameters at the head.

[0055] In particular, to ensure stable connection after structural installation, the internal fixing installation method of the structure is simplified, such as... Figure 2 , Figure 3 As shown, in this embodiment, a cylindrical connecting platform 1e is provided at the top of the fixing hole 1d, and a connecting post 6a that can be inserted into the cylindrical connecting platform 1e is provided at the bottom of the cover plate 6; the connecting post 6a is provided with a bolt mounting hole that can be connected to the fixing hole 1d.

[0056] During installation, by inserting the connecting post 6a into the cylindrical connecting platform 1e and treating the contact surface with a sealing ring or sealant, the water tightness of the installation box 1 can be effectively guaranteed.

[0057] like Figure 2 As shown, the circuit mounting plate 20 includes a connecting portion 200 at the bottom along the left-right direction, and mounting portions 201 located on the front and rear sides of the connecting portion 200;

[0058] The connecting part 200 is snapped downward between the two isolation ribs 11. The bottom of the connecting part 200 is provided with a mounting groove extending in the left and right direction, and the first LED lamp bead group 22 is disposed in the mounting groove.

[0059] The mounting part 201 is provided with holes evenly distributed for connecting the electrode needles 21.

[0060] By making full use of the interlocking connections between the installation structures, the number of fixed structures is reduced, which facilitates assembly and alignment while effectively compressing structural complexity and weight, and optimizing the basic parameters of the device.

[0061] The present invention also provides a method for using the aforementioned fish photoelectric electromagnetic combined control device, which specifically includes the following steps:

[0062] S1. Obtain an adult fish target as the carrier, use local anesthesia, and use the bolt located in the fixing hole 1d to fix the device to the head of the target, so that the bottom opening of the light-passing hole 1a and the light-transmitting lens 50 are located directly above the target's eye.

[0063] S2. Adjust the LED output wavelength according to the control mode, wherein the first LED bead group 22 is used to generate light of the specific wavelength that is used most frequently during the operation and needs to be used as a binocular signal output; wherein the second LED bead group 31 is used to generate light of the specific wavelength that is used less frequently during the operation and needs to be used as a monocular signal output.

[0064] S3. Test the light control effectiveness of the first LED bead group 22 and the second LED bead group 31 under no-light conditions; test the effectiveness of electric control and magnetic control under normal conditions; test the autonomous movement behavior of fish under normal conditions; and adjust the device parameters according to the aforementioned test results.

[0065] The aforementioned normal situation refers to the situation where, after eliminating other interfering factors, a specific item is tested, and the fish's autonomous movement behavior is examined. In this case, photoelectromagnetic stimulation should be stopped, and the impact of the device on the fish's movement and other aspects should be analyzed by judging the fish's autonomous movement behavior.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
