At present, the indoor privacy monitoring window is mainly realized through single-side transmission of glass, and the main principle is that a high-reflection film is evaporated on one side of the glass, when the brightness of the space facing the side is high, the glass can generate high reflection to visible light, and the glass looks like a mirror and cannot penetrate through the glass to see the condition in the room on the other side. And because the glass still has the most basic permeability, personnel in the room on the other side can observe the specific situation in the room on the side of the evaporated high-reflection film through the glass. The window needs to identify the specific room function when being installed, the side coated with the reflecting film is installed to the side of the monitored room, and the irreversibility is realized after the installation is finished. Although the scheme can meet the use requirements of people to a certain extent, the physical implementation method has the characteristic of being irreversible, cannot realize bidirectional control, and brings certain inconvenience to actual use.

Example one
Fig. 1 is a flowchart of a method for controlling a privacy window according to a first embodiment of the present invention, where the embodiment is suitable for a case where privacy rooms are flexibly switched, the privacy window is disposed at a joint between a first room and a second room, the first room includes a first lamp, and the second room includes a second lamp, and the method specifically includes the following steps:
In this embodiment, the privacy window comprises a double layer of ITO glass and a liquid crystal polymer. The ITO glass is manufactured by coating a layer of indium tin oxide (commonly called ITO) film on the basis of sodium-calcium-based or silicon-boron-based substrate glass by a magnetron sputtering method. In this embodiment, specifically, the design of the privacy window requires two ITO glass/plastic conductive substrates, wherein the inner surfaces of the two substrates are coated with a layer of vertical alignment agent (the alignment liquid crystal direction is the cell thickness direction) in a suspended manner, the middle of the substrates is filled with a liquid crystal polymer mixed solution (the invention mainly uses negative liquid crystal mixed with polymer), and after exposure and polymerization under certain conditions, a PSLC (polymer stabilized liquid crystal) structure is formed (when the negative liquid crystal PSLC has no voltage, the refractive index of the liquid crystal extraordinary ray is matched with the refractive index of the polymer, light can pass through the window, the window is in a transparent state, after voltage is applied, the liquid crystal molecules rotate 90 degrees, the refractive indexes of the two materials are not matched, and light cannot pass through the window), wherein the liquid crystal polymer is formed by mixing the negative liquid crystal HNG715600-100 produced by Jiangsu synthetic display technology ltd and the polymer RM257 produced by the company in a mass ratio of, the verification proves that after exposure, the transmittance can reach 100% without voltage, and the transmittance is reduced to 8% after processing the working voltage (about 30V), and light hardly penetrates; the response time under the working voltage can be shortened to about 7 ms.
In this embodiment, the privacy window is disposed at a connection between the first room and the second room, and the condition of controlling whether the privacy window is in a transparent state is achieved by driving voltages of the first lamp in the first room and the second lamp in the second room in the association circuit. Specifically, in this embodiment, the first lamp and the second lamp can be implemented by using LEDs, and the LEDs can be common lamps in the market at present, and in this embodiment, the LEDs with rated voltage of 3V and rated current of 20mA are taken as an example for description.
And step 110, generating a privacy window control voltage after processing the first driving voltage and the second driving voltage.
In this embodiment, the driving voltage of the LED in the first room and the driving voltage of the LED in the second room jointly generate the privacy window control voltage, and the privacy window can accurately switch the transparent or opaque state according to the control voltage. For example, the first driving voltage and the second driving voltage may generate the privacy window control voltage according to a control effect of the logic circuit, and when the first driving voltage and the second driving voltage are simultaneously present, the privacy window control voltage may be generated, and when the first driving voltage and the second driving voltage are not simultaneously present, the privacy window control voltage may not be generated. Alternative embodiments may also use the first drive voltage or the second drive voltage directly as the privacy window control voltage.
And step 120, controlling the transparent state of the privacy window by using the privacy window control voltage.
In this embodiment, a vertical alignment agent is coated on a double-layer ITO glass or a conductive plastic plate in a suspended manner, and then the double-layer ITO glass or the conductive plastic plate is bonded with thermosetting glue, spacer beads are doped in the glue to form a gap with a certain thickness, a liquid crystal filling port is reserved in a path of the thermosetting glue, and a liquid crystal polymer solution is filled through a vacuum isolation system. After the liquid crystal polymer is cured, the polymer in the PSLC structure forms a chain structure, liquid crystal is dispersed in the PSLC structure, and because the vertical orientation layer can orient the long axis direction of the liquid crystal to be the box thickness direction, the refractive index of light rays passing through the liquid crystal follows the refractive index of extraordinary rays under the condition of not applying privacy window control voltage, the light rays can penetrate through the liquid crystal and the window is in a transparent state; after the privacy window control voltage is added, the liquid crystal molecules rotate by 90 degrees, the refractive indexes of the two materials are not matched, most of light rays are scattered and cannot penetrate through, and the privacy window is in an impermeable state.
The embodiment discloses a control method of a privacy window, the privacy window is arranged at a joint of a first room and a second room, the first room comprises a first lamp, the second room comprises a second lamp, the method comprises the following steps: acquiring a first driving voltage of a first lamp and a second driving voltage of a second lamp; processing the first driving voltage and the second driving voltage to generate a privacy window control voltage; controlling a transparency state of a privacy window using the privacy window control voltage. According to the control method of the privacy window, disclosed by the embodiment of the invention, any room can be used as a visual independent privacy room by controlling the intelligent window and the lamps in the two rooms in a circuit correlation manner, so that the problem that the privacy rooms cannot be visually switched in the prior art is solved, the effect of flexibly switching the privacy rooms is realized, and the control method is favorable for meeting the requirements of users.
Example two
Fig. 2 is a flowchart of a method for controlling a privacy window according to a first embodiment of the present invention, where the embodiment is suitable for a case where privacy rooms are flexibly switched, the privacy window is disposed at a joint between a first room and a second room, the first room includes a first lamp, and the second room includes a second lamp, and the method specifically includes the following steps:
And step 210, generating a privacy window control voltage after the first driving voltage and the second driving voltage are processed by AND gate logic.
In this embodiment, referring to fig. 3, fig. 3 is a circuit connection diagram of an LED1 and an LED2 controlling a transmission state of the privacy window PSLC according to a second embodiment of the present invention, where a switch K1 controls whether a power supply is turned on, and a switch K2 and a switch K3 control light emitting conditions of an LED1 and an LED2, respectively. When the voltage at two ends of the PSLC privacy window is 0V, the PSLC privacy window is in a transmission state; when the voltage between both ends is 30V, the liquid crystal display device is in a non-transmission state. When the voltage at two ends of the LED lamp is 0V, the LED lamp is in a turn-off state; when the voltage between the two ends is 3V, the switch is in an open state. When the LED lamp in the room 1 is in a closed state and the intelligent window is in a transparent state, no matter what state the lamp in the room 2 is in, the room 2 cannot see the state in the room 1, and the room 1 can see the state in the room 2, so that one-way visibility is realized; conversely, when the LED in room 1 is in the open state, the smart window is in the opaque state, and no matter what state the light in room 2 is, the two rooms are invisible to each other.
In other embodiments, when the first room is a privacy room, the first driving voltage and the privacy window control voltage are pulsed voltages of a first frequency. When the second room is a privacy room, the second driving voltage and the privacy window control voltage are pulse voltages of a second frequency. The first and second frequencies are greater than 16.7 times per millisecond.
Specifically, when the first frequency and the second frequency are greater than 16.7 times per millisecond, that is, the recognition frequency of the human eye is exceeded, the human eye stays in the initial observation state. When the first room is a privacy room, if the first driving voltage and the privacy window control voltage are both pulse voltages of 16.7 times per millisecond, and whenever the privacy window control voltage is a pulse high voltage, the window is in a transparent state, a person in the first room can see light transmitted from the second room at a frequency of 16.7 times per millisecond and observe the second room, and the person in the first room can consider the smart window to be in a transparent state due to human eye delay. At this time, because the light emitting frequency of the first lamp is consistent with the closing frequency of the intelligent window, namely when the control voltage of the privacy window is pulse high voltage and the window is in an opaque state, light emitted to the second room by the first lamp at 16.7 times per millisecond frequency in the first room is just completely blocked by the window in the opaque state, so that people in the second room can not observe any light in the first room in the privacy state, and the first room can be viewed in one direction in the second room;
similarly, when the second room is the privacy room, if the second driving voltage and the privacy window control voltage are both pulse voltages of 20 times per millisecond, when the window is in a transparent state every time the privacy window control voltage is a pulse low voltage, a person in the second room can see the light transmitted from the first room and observe the first room at a frequency of 20 times per millisecond, and the person in the second room can consider the smart window to be in a transparent state due to the time delay of the eyes of the person. At this moment, because of the second lamps and lanterns luminous frequency and the closing frequency unanimity of intelligent window, namely when privacy window control voltage was the pulse low voltage, when the window was in the impenetrable state, because of the second lamps and lanterns just in time all are blocked by the window that is in the impenetrable state to the light of first room with 20 times every millisecond frequency luminous illumination in the second room for people in the first room can not observe any light in the second room of privacy state at all, consequently this second room one-way visual first room. Taking the circuit in fig. 3 as an example, when the switch K1 and the switch K2 are turned off and the switch K3 is turned off at the same time, the first room is one-way visible to the second room; when the switch K1 and the switch K3 are closed and the switch K2 is opened at the same time, the second room can unidirectionally view the first room. Since the driving voltage of the LED is much smaller than that of the PSLC, a resistance of about 1.35k Ω is added to the circuit.
In this embodiment, when the first driving voltage of the first lamp and the second driving voltage of the second lamp exist at the same time, the privacy window maintains an opaque state. Specifically, the first lamp first driving voltage is an on voltage (to light the lamp), and the second lamp second driving voltage is an off voltage (to light the lamp). The double-layer ITO glass or the conductive plastic plate is coated with a vertical orientation agent in a hanging mode, then the double-layer ITO glass or the conductive plastic plate is bonded through thermosetting glue, spacer balls are doped in the glue to form a gap with a certain thickness, a liquid crystal filling port is reserved in a thermosetting glue path, and liquid crystal polymer solution is filled through a vacuum isolation system. After the liquid crystal polymer is cured, the polymer in the PSLC structure forms a chain structure, liquid crystal is dispersed in the PSLC structure, and because the vertical orientation layer can orient the long axis direction of the liquid crystal to be the box thickness direction, the refractive index of light rays passing through the liquid crystal follows the refractive index of extraordinary rays under the condition of not applying privacy window control voltage, the light rays can penetrate through the liquid crystal and the window is in a transparent state; after the privacy window control voltage is added, the liquid crystal molecules rotate by 90 degrees, the refractive indexes of the two materials are not matched, most of light rays are scattered and cannot penetrate through, and the privacy window is in an impermeable state.

According to the control circuit of the privacy window, disclosed by the embodiment of the invention, any room can be used as a visual independent privacy room by controlling the intelligent window and the lamps in the two rooms in a circuit correlation manner, so that the problem that the privacy rooms cannot be visually switched in the prior art is solved, the effect of flexibly switching the privacy rooms is realized, and the control circuit is favorable for meeting the requirements of users.
Example four
Fig. 5 is a schematic structural diagram of an isolation system provided in an embodiment of the present invention, as shown in fig. 5, the isolation system includes a first room a, a second room B, a first luminaire LED1, a second luminaire LED2, and a privacy window C, and specifically, the isolation system provided in this embodiment is configured to perform the following methods:
the privacy window is arranged at a joint of a first room and a second room, the first room comprises a first lamp, the second room comprises a second lamp, and the privacy window comprises:
acquiring a first driving voltage of a first lamp and a second driving voltage of a second lamp;
processing the first driving voltage and the second driving voltage to generate a privacy window control voltage;
controlling a transparency state of a privacy window using the privacy window control voltage.
In the present embodiment, the privacy window C is provided at the junction of the first room a and the second room B, and the condition of controlling whether the privacy window C is in the transparent state is achieved by the driving voltages of the first lamp LED1 in the first room a and the second lamp LED2 in the second room B in the association circuit. The driving voltage of the LED in the first room A and the driving voltage of the LED in the second room B jointly generate a privacy window C control voltage, and the privacy window C can accurately switch a transparent state or an opaque state according to the control voltage. For example, the first driving voltage and the second driving voltage may generate the privacy window C control voltage according to a control effect of the logic circuit, and the privacy window C control voltage may be generated when the first driving voltage and the second driving voltage are simultaneously present, and may not be generated when the first driving voltage and the second driving voltage are not simultaneously present. Alternative embodiments may also use the first driving voltage or the second driving voltage directly as the privacy window C control voltage.
When the first room a is a privacy room, if the first driving voltage and the privacy window C control voltage are both pulse voltages of 16.7 times per millisecond, then whenever the privacy window C control voltage is a pulse low voltage, the window is in a transparent state, a person in the first room a can see the light transmitted from the second room B and observe the second room B at a frequency of 16.7 times per millisecond, and the person in the first room a can consider the smart window to be in a transparent state due to the human eye delay. At this time, because the light emitting frequency of the first lamp LED1 is consistent with the closing frequency of the smart window, that is, whenever the control voltage of the privacy window C is a pulse high voltage, and the window is in the opaque state, the light emitted by the first lamp LED2 at 16.7 times per millisecond frequency to the second room B in the first room a is just completely blocked by the window in the opaque state, so that people in the second room B cannot observe any light in the first room a in the privacy state, and therefore the first room a can unidirectionally view the second room B;
similarly, when the second room B is the privacy room, if the second driving voltage and the privacy window C control voltage are both 20 times pulse voltages per millisecond, then whenever the privacy window C control voltage is a pulse low voltage, the window is in the transparent state, the person in the second room B can see the light transmitted from the first room a and observe the first room a at a frequency of 20 times per millisecond, and the person in the second room B can consider the smart window to be in the transparent state due to the human eye delay. At this time, since the light emitting frequency of the second lamp LED2 is the same as the closing frequency of the smart window, that is, whenever the control voltage of the privacy window C is a pulse high voltage, the window is in the opaque state, and the light emitted to the first room a by the second lamp LED2 at 20 times per millisecond frequency in the second room B is just completely blocked by the window in the opaque state, so that the person in the first room a cannot observe any light in the second room B in the privacy state, and therefore the second room B can unidirectionally view the first room a.
In one embodiment, the computer isolation system provided in the embodiment of the present invention is not limited to the above method operations, and may also perform related operations in the control method of the privacy window provided in any embodiment of the present invention.
