Description
Technical Field
The invention relates to an infrared touch screen capable of achieving night vision compatibility.
Background
The infrared touch screen is widely used in the field of onboard touch control due to the advantages of high light transmittance, accurate positioning, strong stability and the like. Currently, 2 sets (AB) of infrared scanning lamps are backed up by each other and distributed in a staggered manner in an airborne infrared touch screen, as shown in fig. 1.
For airborne display, night vision compatibility means that the lights in the cabin do not interfere with NVIS (night vision system) and remain visible to the naked eye.
The pilot wears an onboard helmet mounted NVIS night vision goggles that respond to visible to near infrared light with a wavelength of 930 nm. Helmet night vision goggles are used by pilots to view the external environment and objects only when they are working at night.
At present, the operating wavelength of an infrared emission lamp used by an airborne infrared touch screen is 850nm-1000nm, the wavelength of the infrared emission lamp and the wavelength of a night vision goggles have an overlapping area, light emitted by the infrared lamp irradiates on glass at the top and the side of an engine room, and partial light possibly reflects to influence a pilot to observe external conditions through the night vision goggles, so that night vision compatibility of the infrared touch screen is very important.
In order to solve the problem of infrared night vision compatibility, 1300nm transmitting and receiving paired lamps can be used, and under night vision goggles, a light source can not be seen, but a receiving end can not receive signals in a long distance. Because the 1300nm infrared receiving tube adopts a photosensitive diode, the generated photocurrent is very weak, and the situation that the receiving end is difficult to receive signals is easy to occur under the long-distance transmission. In addition, 1300nm infrared geminate transistors are not special for touch screens, need customization, are high in cost and high in cost, and therefore the scheme is not the optimal choice.
Disclosure of Invention
The invention aims to provide an infrared touch screen for solving night vision compatibility, the infrared touch screen is added with a night working mode of the infrared touch screen, the night vision compatibility problem of the infrared touch screen is effectively solved, and the safety performance is improved through airborne flight test.
In order to achieve the above purpose, the present invention provides an infrared touch screen for solving night vision compatibility, the infrared touch screen includes two sets of infrared lamps a and B which are backup to each other, the two sets of infrared lamps are distributed around the infrared touch screen in a staggered manner, and the infrared touch screen can switch between a day mode and a night mode when receiving a working command sent from the outside.
Preferably, when the infrared touch screen operates in a daytime mode, the two sets of infrared lamps A, B are used as backups for each other in order to avoid abnormal operation caused by strong light interference; when one set of the infrared touch screen can not work normally under the interference of strong light, the system is immediately switched to the other set of the infrared touch screen to ensure that the infrared touch screen can work normally.
Preferably, when the infrared touch screen operates in a night mode, the luminous intensity of the infrared lamp tube is reduced to reduce interference of the infrared light to night vision.
Preferably, the night mode comprises a static touch-free working mode, at the moment, the transverse transmitting tube only has the upper transmitting lamp, namely the B-set transmitting lamp works, and the vertical left and right transmitting lamps do not work, so that no infrared light irradiates the top of the cabin and the side glass, and the interference of reflected light to the sight of a pilot is avoided.
Preferably, the night mode further comprises a touch working mode, and at the moment, when the B sets of transverse long-edge receiving lamps in work detect that a touch exists, the vertical short-edge transmitting and receiving lamps of the screen are started.
According to the technical scheme, the invention designs an infrared night working mode aiming at the infrared touch screen. When a pilot observes external conditions, the touch screen does not need to be touched, so that the touch screen is designed to be in a night working mode, the vertical edge infrared lamp tube of the screen does not emit light when no touch occurs, and the transverse edge infrared lamp only keeps the lamp tubes from top to bottom to continue to emit, so that the working brightness of the lamp is reduced at the same time. The transverse edge infrared lamp only keeps the lamp tubes from top to bottom to continuously emit light, and the infrared light only irradiates the bottom of the cabin from top to bottom, so that the interference of the infrared light irradiating the top of the cabin and reflecting the infrared light to the eyes of a pilot on sight is avoided; and the vertical edge infrared lamp tube does not emit light, so that infrared rays are prevented from irradiating the side of the engine room and being emitted. Therefore, the method overcomes the reflection interference which can occur when infrared light irradiates on the glass at the top and the side of the cabin, the visual field of a pilot is not interfered by the infrared light emitted by the touch screen when the pilot observes the external condition through the night vision device, and the safety is greatly improved.
Additional features and advantages of the invention will be set forth in the detailed description which follows.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, unless otherwise specified, the directional words "upper, lower, left, right" and the like included in the terms merely represent the orientation of the terms in a conventional use state or are colloquially understood by those skilled in the art, and should not be construed as limiting the terms.
The invention provides an infrared touch screen capable of achieving night vision compatibility, which comprises an A set of infrared lamps and a B set of infrared lamps which are backup to each other, wherein the two sets of infrared lamps are distributed around the infrared touch screen in a staggered mode, and the infrared touch screen can be switched between a day mode and a night mode when receiving a working command sent from the outside.
As shown in fig. 2, the touch screen works in the daytime (day mode), the pilot does not use night vision goggles to observe the target, but in order to avoid abnormal work possibly caused by strong light interference, two sets of infrared lamps A, B are backup for each other, when one set of infrared lamps is interfered by the strong light and can not work normally, the system is switched to the other set of infrared lamps immediately, and the infrared touch screen can work normally. Wherein, A set of infrared lamp includes A set of emission lamp and A set of receiving lamp, and B set of infrared lamp includes B set of emission lamp and B set of receiving lamp.
During night flight, because of no strong light interference possibly encountered in the daytime, the infrared touch controller receives a night mode work command sent by the outside, and the infrared touch controller can be immediately switched to the night mode to work (night mode). The infrared touch works in a night mode and has the following changes:
first, the emission intensity of the infrared lamp decreases. The working environment is in a dark environment, the night vision goggles enter a night mode, compared with the working environment condition of the day mode, the external interference in the night mode is small, and a high signal to noise ratio is not needed, so that the interference of infrared light to night vision can be reduced by reducing the luminous intensity of the infrared lamp tube in the night mode.
And secondly, a static non-touch mode and a touch working mode are adopted in the scanning mode. The static touchless operating mode is shown in fig. 3. The transverse transmitting tube only works as an upper transmitting lamp (B sets of transmitting lamps), and the vertical left and right edge transmitting lamps do not work. The design work like this, infrared light can not shine on cabin top and side glass, avoids the interference that the reflection light probably has to pilot's sight.
When the aircraft observes the external conditions through the engine room cover, touch operation is not carried out, the sight of the pilot is not interfered by infrared rays in a static touch-free working mode, and the external conditions can be well observed.
When the flight person touches, night vision mirror gets into touch mode, see fig. 4, and the horizontal long limit receiving lamp of B set in the work detects there is the touch, launches the vertical minor face transmission of screen this moment, receiving lamp, but the pilot does not observe external conditions this moment, consequently does not influence the sight.
The technical scheme of the application is directed at an infrared touch screen, and an infrared night working mode is designed. Under the night mode, it is external environment that the pilot need observe during static nothing touch, and vertical minor face infrared lamp is luminous this moment, and horizontal long limit infrared lamp only stays the part transmission from top right to bottom, and the luminance of lamp reduces simultaneously, has avoided infrared light to shine cabin side and top glass. The pilot observes the external condition through the night-vision device and is no longer disturbed by the infrared ray of touch-sensitive screen. At night, a pilot performs touch operation, the night vision goggles enter a touch working mode, the vertical short edge transmitting and receiving lamp of the screen is started when the touch is detected, at the moment, the pilot does not need to observe external conditions, and therefore the pilot is not interfered by reflected light even if the reflected light exists.
Therefore, the night vision compatibility problem of the night vision goggles can be effectively solved by aiming at the night mode additionally arranged on the infrared touch screen; the day mode can effectively improve the strong light interference and passes the airborne flight test.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.
It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and the invention is not described in any way for the possible combinations in order to avoid unnecessary repetition.
In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
