Description

Technical Field

[0001] The invention belongs to the technical field of aircraft lighting, and in particular relates to a laser search light lighting system with a one-button homing function. Background Art

[0002] The search light system is used to search for targets at night or in low visibility. The left and right and pitch angles are controllable. It can be used for helicopters, ships, vehicles, etc. The existing search lights are used for long-distance search. They cannot illuminate flammable objects and search and rescue personnel within 30 meters. The illumination light intensity is strong and suitable for search tasks at an altitude of 500 to 1000 meters. The search light system is mainly composed of search lights, junction boxes, control boxes and finished cables. Generally, xenon lamps are used as light sources. The control is relatively simple. The search lights generally use a separate control system, and the search lights are xenon lamp bulbs with low reliability and high illumination temperature, which results in the search lights not allowing flammable objects in the near range of illumination, and not being able to illuminate the equipment or structures on the aircraft. Therefore, the rotation angle of the search light is limited, and the original search light bulb is complicated to start, and a separate junction box is required to convert the instructions issued by the search light control box to control the search light. At present, the conventional search lights mainly have poor reliability, limited rotation illumination range of the search and rescue lighting, and difficult operation of the search and rescue lighting by the crew. Summary of the invention

[0003] The main purpose of the present invention is to optimize the following problems by selecting a new type of laser search light illumination system with a one-button homing function:

[0004] a) The use of laser light sources can greatly improve the reliability of searchlights;

[0005] b) Increase the rotational illumination range of search and rescue lighting;

[0006] c) It can reduce the crew's burden of operating search and rescue lights;

[0007] d) It can follow the optoelectronic system to improve the image quality of the optoelectronic system.

[0008] Technical solution: To achieve the above purpose, the present invention designs a laser search and rescue lighting system with a one-button homing function, the system is composed of a control box, a control box separation socket, a search light separation socket, a search light, an optoelectronic system separation surface, an optoelectronic system stabilizing turret, a power fuse, a power negative line grounding point and a conductor;

[0009] The control box is connected to the search light through the control box separation socket and the search light separation socket in turn, and controls the search light 4 to realize the conversion of different modes; the photoelectric system stabilizing turret is connected to the search light through the photoelectric system separation surface and the search light separation socket in turn, and the search light 4 and the photoelectric system stabilizing turret 6 realize the follow-up function;

[0010] The power fuse is connected to the search light through the search light separation socket to provide power; the power negative line grounding point is connected to the search light through the search light separation socket to provide a grounding point for the search light.

[0011] Furthermore, the control box is provided with a "LAMP / ON / OFF" control switch, which has a one-key reset and power-off function. When the switch is placed in the "OFF" position, the search light automatically resets and the system is powered off.

[0012] Furthermore, the control box is also provided with a "light source on" interface, a "light source off" interface, and a "reset" interface;

[0013] The No. 7 terminal of the "light source on" interface on the control box is connected to the No. 7 terminal of the search light separation socket interface through the control box separation socket and the No. 7 terminal of the search light separation socket interface and the No. 7 terminal on the search light to control the lighting of the search light;

[0014] The "light source off" interface No. 8 on the control box is connected to the No. 8 terminal on the search light through the control box separation socket and the search light separation socket interface No. 8 to control the extinguishing of the search light;

[0015] Terminal 9 of the "reset" interface on the control box is connected to terminal 9 on the search light through the control box separation socket and terminal 9 of the search light separation socket interface to control the reset terminal of the search light.

[0016] Furthermore, the search light system communicates with the optoelectronic system stabilization turret through the RS-422 interface, and the No. 14 terminal "RS-422TX+" on the search light is connected to the U terminal of the optoelectronic system separation surface interface through the No. 14 terminal of the search light separation socket interface; the U terminal of the detection system separation surface interface communicates with the T terminal "B_RXO+" of the optoelectronic system stabilization turret.

[0017] Furthermore, terminal No. 15 "RS-422TX-" on the searchlight is connected to terminal T of the optoelectronic system separation surface interface through terminal No. 15 of the searchlight separation socket interface; terminal T of the detection system separation surface interface communicates with terminal S of the optoelectronic system stabilization turret interface "B_RXO-".

[0018] Further, the No. 16 terminal "RS-422RX+" on the searchlight is connected to the R terminal of the optoelectronic system separation surface interface through the No. 16 terminal of the searchlight separation socket interface; the R terminal of the detection system separation surface interface communicates with the P terminal of the optoelectronic system stabilization turret interface "B_TXO+";

[0019] Further, the terminal 17 "RS-422RX-" on the searchlight is connected to the terminal S of the optoelectronic system separation surface interface through the terminal 17 of the searchlight separation socket interface; the terminal S of the detection system separation surface interface communicates with the terminal R of the optoelectronic system stabilization turret interface "B_TXO-";

[0020] Furthermore, terminal 18 "GND" on the search light is connected to terminal P of the optoelectronic system separation surface interface through terminal 18 of the search light separation socket interface; terminal P of the detection system separation surface interface communicates with terminal L of "GND" of the optoelectronic system stabilization turret interface.

[0021] Furthermore, terminal 18 "GND" on the search light is connected to terminal P of the optoelectronic system separation surface interface through terminal 18 of the search light separation socket interface; terminal P of the detection system separation surface interface communicates with terminal L of "GND" of the optoelectronic system stabilization turret interface.

[0022] Furthermore, the search and rescue lighting system uses laser as a light source.

[0023] Technical effect: The original searchlight is a separately controlled system, and the searchlight is a xenon lamp with low reliability and high irradiation temperature, so that flammable objects are not allowed to be in the close range of the searchlight, and the equipment or structure on the aircraft cannot be irradiated. Therefore, the rotation angle of the searchlight is limited, and the original searchlight bulb is complicated to start, and a separate junction box is required to convert the instructions issued by the searchlight control box to control the searchlight.

[0024] The new searchlight uses a laser light source, which will greatly improve the reliability index and solve the problem of heat radiation from the light source. The rotation angle of the searchlight is no longer affected by irradiating nearby fuselages or equipment. The relaxation of the rotation angle will greatly improve the operability of the searchlight.

[0025] The cancellation of the original system junction box frees up space for cabin layout and reduces cable connections.

[0026] The addition of one-button reset and system power-off functions to the search light control reduces the burden on the crew;

[0027] The follow-up function has been added, and visible light illumination has been added when the electro-optical pod searches for targets, making the electro-optical display clearer and more recognizable. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. 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 technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See attached Figure 2 In the specific implementation process of the present invention, a laser search and rescue lighting system with a one-key homing function is proposed, which is composed of a control box 1, a control box separation socket 2, a search light separation socket 3, a search light 4, an optoelectronic system separation surface 5, an optoelectronic system stabilizing turret 6, a power fuse 7, a power negative line grounding point 8 and a conductor;

[0034] The control box is connected to the search light 4 through the control box separation socket 2 and the search light separation socket 3 in sequence, and controls the search light 4 to realize the conversion of different modes; the photoelectric system stabilizing turret 6 is connected to the search light 4 through the photoelectric system separation surface 5 and the search light separation socket 3 in sequence, and the search light 4 and the photoelectric system stabilizing turret 6 realize the follow-up function;

[0035] The power fuse 7 is connected to the search light 4 through the search light separation socket 3 to provide power; the power negative line grounding point 8 is connected to the search light 4 through the search light separation socket 3 to provide a grounding point for the search light 4.

[0036] Embodiment 1:

[0037] 1) Use laser as light source

[0038] The laser light source has strong emission capability and highly concentrated energy. To reduce power consumption, under the same light intensity index and input voltage, the working current is reduced from 55A to 17A and the reliability index of the search light is increased from a maximum of 1000h or 2 years to 6000h.

[0039] Laser is selected as the light source of the searchlight. Compared with xenon lamps, laser light sources radiate less heat and will not cause damage to the aircraft structure that may be irradiated. Therefore, there is no need to limit the rotation angle of the searchlight, but it is necessary to avoid affecting the crew.

[0041] The "LAMP / ON / OFF" control switch has a one-touch reset and power-off function. When the switch is in the "OFF" position, the search light automatically resets and the system is powered off. This will reduce the workload for the crew, allowing the search light to reset before the helicopter lands, avoiding the danger of the search light touching the ground due to excessive landing load.

[0042] The "light source on" interface No. 7 on the control box 1 is connected to the No. 7 terminal on the search light 4 through the control box separation socket 2 and the search light separation socket 3 interface No. 7 terminal to control the lighting of the search light;

[0044] The "reset" interface No. 9 on the control box 1 is connected to the No. 9 terminal on the search light 4 through the control box separation socket 2 and the search light separation socket 3 interface No. 9 terminal to control the search light reset terminal.

[0045] 3. Follow-up function of search light and optoelectronic system stabilizing turret

[0049] The No. 17 terminal "RS-422RX-" on the searchlight 4 is connected to the S terminal of the interface of the optoelectronic system separation surface 5 through the No. 17 terminal of the searchlight separation socket 3 interface; the S terminal of the interface of the detection system separation surface 5 communicates with the R terminal of the interface "B_TXO-" of the optoelectronic system stabilization turret 6;

[0050] Terminal No. 18 "GND" on the search light 4 is connected to the P terminal of the optoelectronic system separation surface 5 interface through terminal No. 18 of the search light separation socket 3 interface; the P terminal of the detection system separation surface 5 interface communicates with the L terminal "GND" of the optoelectronic system stabilization turret 6 interface.

[0052] In the present invention, the searchlight uses a laser light source, which will greatly improve the reliability index and solve the problem of heat radiation of the light source. The rotation angle of the searchlight is no longer affected by irradiating nearby fuselages or equipment. The relaxation of the rotation angle will greatly improve the operability of the searchlight.
