Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of window curtains, in particular to an intelligent louvered window curtain system and a control method thereof. BACKGROUND

[0002] With the satisfaction of basic material life of society, further healthy and comfortable indoor space environment has become the hotspot and trend of people's research and pursuit. Good indoor environment can provide people with safe and comfortable living conditions, and is also conducive to people's efficient work or other activities.

[0003] Modern office tasks require more and more brain power of workers. Studies have shown that the light of indoor working environment has a not small influence on people's work efficiency. For example:

[0004] In 2001, Shimomura et al. studied the influence of light source color temperature on the arousal level of personnel during brain work. Studies have shown that when the light source color temperature is high, the excitability and activity of the human brain are improved.

[0005] In 2006, Shi Lu studied the influence of light source color temperature change on the central nervous system, psychology and physiological function of human body. Through analysis, it is known that the function of the central nervous system of the human body will be affected by the change of indoor lighting color temperature.

[0006] In 2014, Zhang Yanmei and Zheng Jie of Chongqing University combined the knowledge of cognitive psychology and physiology, designed five illumination experimental conditions of 50lx, 100lx, 300lx, 500lx and 800lx, used the cognitive ability test project designed in advance to meet the work efficiency evaluation model, collected the heart rate and blood pressure signals of the subjects, and combined with the subjective evaluation, analyzed the changes of cognitive ability test results, subjective evaluation results, heart rate and blood pressure in different illumination environments, so as to analyze the influence of different illumination on the work efficiency of personnel.

[0007] In 2018, Wu Wenmiao and Yang Yalong designed an experiment: the experimental thermal environment was controlled at 24±1℃, three illumination conditions of 100lx, 300lx and 1000lx were set, three color temperature conditions of 3000K, 4000K and 6500K were set, when the experiment was carried out in different illumination environments, the color temperature was controlled at 4000K, when the experiment was carried out in different color temperature environments, the illumination was controlled at 300lx, a total of five experimental conditions were set. The influence of indoor illumination and color temperature on work efficiency was studied. Studies have shown that low illumination and low color temperature environment will reduce work efficiency, standard illumination and color temperature environment will improve work efficiency, and high illumination and high color temperature environment will also improve work efficiency in the case of short-term exposure.

But these studies have certain limitations, only verification, not good combination into the actual working environment. Therefore, how to further apply these theoretical research to the actual working environment is the problem to be solved at present.

DETAILED DESCRIPTION

[0038] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] Luminous flux refers to the radiation power that can be sensed by the human eye, which is equal to the product of the radiation energy of a certain waveband per unit time and the relative visibility of the waveband. Since the relative visibility of the human eye to light of different wavelengths is different, the luminous flux of light of different wavelengths is not equal when the radiation power is equal. The unit of luminous flux is lm (lumen).

[0040] Illuminance, also known as light intensity or illumination, is commonly known as lux, which represents the luminous flux received by the surface of the subject per unit area. 1 lux is equivalent to 1 lumen per square meter, that is, the luminous flux of the subject per square meter of area is vertically irradiated by a light source with a distance of 1 meter and a luminous intensity of 1 candle. The unit of illumination is lux (lx).

[0041] As Figures 1-10 The intelligent venetian blind system of the present application shown in the figure comprises a blind piece 1 and a blind box 2 with an electric control system 3. The blind piece 1 is V-shaped and comprises an outer blind piece 11 and an inner blind piece 12. It is worth noting that the V-shaped blind piece 1 (which can not be split into an outer blind piece 11 and an inner blind piece 12 and is vertically wound by a winding device, but the application is relatively small and not practical) has the following characteristics in use compared with the conventional S, L and other designs of the prior art: when the angle is appropriate, it is inverted V-shaped or reversed normal V-shaped, and there is no gap in the downward blind piece quality inspection, which can meet the light shielding requirement and has a V-shaped air flow channel, and the side rail frame 41 and the adsorption structure on both sides realize the windproof limiting of the blind piece 1, so that the first characteristic effect of the present application is that the blind piece can simultaneously have the ventilation + light shielding effect in the normal use state, which is a characteristic effect that general blind pieces do not have. On this basis, the present application designs the blind piece 1 to be hinged between the outer blind piece 11 and the inner blind piece 12, which can be horizontally expanded without losing the general single-layer blind piece design and can be V-shaped ventilation and light shielding. Figure 6

[0042] As described above, the blind piece 1 of the present application is designed to be hingedly arranged between the outer blind piece 11 and the inner blind piece 12, and further comprises a turnover system 4 for controlling the relative swinging of the outer blind piece 11 and the inner blind piece 12. The turnover system 4 is connected to the electric control system 3, and the electric control system 3 is further provided with a plurality of brightness detection units for detecting the indoor environment brightness and a camera dynamic capture unit 35 for detecting the activity status of personnel.

[0043] ​As the structure is set as above, the outer curtain piece 11 and the inner curtain piece 12 of the shutter curtain system of the present application can be independently turned over, thereby forming various shapes of the curtain pieces, from a single structure to a V-shaped structure with any included angle. One of the features of the present application is that by controlling the relative swinging of the two curtain pieces, the swinging is centered at the middle hinge point, thereby forming various light transmission and reflection modes, to obtain a more comfortable indoor lighting environment. The electric control system 3 of the present embodiment cooperates with the program to demarcate various areas in the room by the dynamic camera capturing unit 35 based on machine vision, and the brightness detection unit arranged in each area is used for feedback. The position of the person, the brightness of the position area, and the program triggering the brightness adjustment of the area are used for triggering the program to adjust the brightness of the area. The adjustment principle includes adjusting the angle of light transmission by turning over the curtain piece, and reflecting the outdoor natural light to the indoor by the mirror on the back of the curtain piece, thereby controlling the indoor brightness. The specific structure and principle of the improvement of the present application are as follows:

[0044] As a further arrangement of the above-mentioned scheme, the turning system 4 of the present application includes a side rail frame 41 arranged along the lifting direction of the shutter curtain piece 1. The side rail frame 41 is in a U-shaped structure, and either one end or both ends of the shutter curtain piece 1 are arranged in the opening of the side rail frame 41. The side rail frame 41 further comprises an adjusting mechanism 42 with a permanent magnet 43, and the end of the shutter curtain piece 1 arranged in the side rail frame 41 is provided with an adsorption block 44 connected with the adjusting mechanism 42.

[0045] As the shutter curtain piece 1 of the present application is arranged in the U-shaped structure of the side rail frame 41 after being released by the rope winder 32, and the end adsorption block 44 of the shutter curtain piece 1 is adsorbed with the adjusting mechanism 42, the adjusting mechanism 42 can drive the outer curtain piece 11 or the inner curtain piece 12 to swing along the hinge point, thereby realizing the angle control of the curtain piece.

[0046] As a further arrangement of the above-mentioned scheme, the adjusting mechanism 42 further comprises an arc-shaped rail 421, and the arc-shaped rail 421 is arranged in the same horizontal direction and has two arc-shaped rails 421 corresponding to the outer curtain piece 11 and the inner curtain piece 12, respectively. Each of the arc-shaped rails 421 is provided with a permanent magnet 43, and the permanent magnet 43 is movable along the corresponding arc-shaped rail 421, thereby driving the shutter curtain piece 1 adsorbed therewith to relatively turn over along the hinge point of the corresponding outer curtain piece 11 and inner curtain piece 12, to control the included angle change of the shutter curtain piece 1.

[0047] Through the above structure, the adjusting mechanism 42 of the present application includes a permanent magnet 43 to be attracted to the adsorption block 44, and the arc rail 421 is arranged to allow the permanent magnet 43 to move along the arc rail 421, and the arc rail 421 is horizontally open. When the permanent magnet 43 moves up and down along the arc rail 421, the hinge point of the outer curtain piece 11 or the inner curtain piece 12 does not move, and the outer curtain piece 11 or the inner curtain piece 12 is pulled by the adsorption block 44 to swing, and the outer curtain piece 11 is turned upward from the outer side, and then it is horizontal and then downward, or it is downward from the outer side, and then it is horizontal and then upward. Each louver piece 1 is independently controlled, and the outer curtain piece 11 and the inner curtain piece 12 of each louver piece 1 can also be independently controlled. The specific principle and structure are as follows:

[0048] As a further arrangement of the above-mentioned scheme, the permanent magnet 43 of the present application includes a sliding sleeve 431 with an inner telescopic hole 432, a permanent magnet block 433 axially movable towards or away from the adsorption block 44 in the inner telescopic hole 432, a movable motor 434 for driving the permanent magnet block 433 to axially move, and a driving structure 435 for driving the permanent magnet 43 to move along the arc rail 421. The inner telescopic hole 432 is provided with an inner threaded section 4321, and the permanent magnet block 433 is provided with an outer threaded section 4331 corresponding to the inner threaded section 4321. The movable motor 434 is used to drive the permanent magnet block 433 to rotate and telescope. Through the above structure, the corresponding permanent magnet 43 of the adsorption block 44 provided at the end of the louver piece 1 includes a permanent magnet block 433 that moves towards or away from the adsorption block 44. By setting the inner and outer threaded structure, the movable motor 434 drives the permanent magnet block 433 to rotate, and the sliding sleeve 431 with the inner thread is screwed, and the threads between the two are screwed, so as to realize the action of the permanent magnet block 433 moving towards or away from the adsorption block 44. When the permanent magnet block 433 moves towards the adsorption block 44, it is attracted to the adsorption block 44, that is, the outer curtain piece 11 or the inner curtain piece 12 of the louver piece 1 will only swing when the permanent magnet 43 slides along the arc rail 421. Conversely, the two are disconnected. The purpose of this linkage and disconnection is that, referring to the existing technology of louver winding design, if a rope winding device and a ladder rope are designed, the ladder rope can be wound by the rope winding device, and the louver piece 1 can be stacked and stored. The storage state of the louver piece 1 should be in a horizontal flat state.

[0049] As a further arrangement of the above solution, the permanent magnet piece 43 is provided with an electromagnetic clutch assembly 436, the electromagnetic clutch assembly 436 comprises a rotating disc gear 437 connected with the permanent magnet piece 43, the driving structure 435 comprises a forward-reverse servo motor 4351 arranged in the curtain box 2 and a plurality of sets of meshing and linkage rotating gears 4352, the rotating disc gear 437 is provided with an electromagnet 4371 for driving the rotating disc gear 437 to axially move and mesh and link with the rotating gear 4352, and a spring piece 4372 for driving the rotating disc gear 437 to separate from the rotating gear 4352.

[0050] Through the above structural arrangement, the above structure plays a role in the present application. Through the arrangement of the electromagnetic clutch assembly 436, the electromagnet 4371 is energized to attract the rotating disc gear 437 to axially move, thereby meshing and linking with the rotating gear 4352, thereby rotating based on the rotating rotating gear 4352, driving the permanent magnet piece 43 to rotate, thereby making the permanent magnet piece 43 move along the arc rail 421, driving the swing of the curtain piece. It is worth noting that, in the use of the embodiment of the application, when the rotating gear 4352 and the rotating disc gear 437 are axially meshed, the possible tooth misalignment problem is solved by the continuous attraction of the electromagnet 4371 to axially move and smoothly mesh after rotating a small angle.

[0051] As a further arrangement of the above solution, the servo motor 4351, the electromagnetic clutch assembly 436, and the activity motor 434 are electrically connected to the electric control system 3, and are started or stopped by the control signal sent by the electric control system 3. The camera dynamic capture unit 35 and the brightness detection unit are used to monitor the illumination brightness and personnel position of each area in the room, and feed back signals to the electric control system 3.

[0052] As a further arrangement of the above solution, the adsorption block 44 is arranged at one end of the outer curtain piece 11 and the inner curtain piece 12 away from the hinge, the outer curtain piece 11 and the inner curtain piece 12 are made of aluminum or PVC material, and the surface of the outer curtain piece 11 and the inner curtain piece 12 facing the curtain box 2 is provided with a mirror structure, and the surface of the outer curtain piece 11 away from the curtain box 2 is provided with LED light beads 19 connected with the electric control system 3.

[0053] Through the structure setting, the mirror surface structure of the outer curtain piece 11 and the inner curtain piece 12 of the embodiment is used to form a mirror surface effect after the curtain piece included angle is adjusted through a program, more light is reflected into the room through the mirror surface when the indoor and outdoor light is not very strong, and further, when the outdoor light is not enough to reach the desired brightness, the light can be supplemented through the LED light beads 19. It is worth noting that the light supplement of the embodiment is different from the direct light supplement of the prior art, the light supplement of the embodiment is to reflect the light of the LED light beads 19 of the upper layer outer curtain piece 11 upward through the mirror surface structure of the shutter piece 1, compared with the light supplement scheme of the prior art, the light of the embodiment is not directly reflected but is diffusely reflected through the mirror surface, which is more soft and closer to the natural light state, and a better comfortable feeling is obtained.

[0054] As a further setting of the above scheme, the shutter piece 1 is provided with a side rail frame 41 at both ends, the side rail frame 41 is provided with an adjusting mechanism 42 and an adsorption block 44 opposite to the adjusting mechanism 42, the adjusting mechanisms 42 in the side rail frames 41 at both ends of the shutter piece 1 are synchronously actuated through a linkage rod mechanism 49, and the linkage rod mechanism 49 comprises a synchronous wheel 491 and a synchronous rod 492.

[0055] The structure is set to link the adjusting mechanisms 42 on both sides, so that the turning direction and angle of the outer curtain piece 11 or the inner curtain piece 12 of the same shutter piece 1 are the same, and the problems of inclination and angle deviation are avoided.

[0056] The application further includes a control method of an intelligent shutter curtain system, the shutter curtain system is used to divide a room in which the shutter curtain system is installed into regions through a program built in an electric control system 3, capture the moving and staying position region of indoor personnel through a camera dynamic capture unit 35, detect the light intensity of the region in which the personnel stay through a plurality of brightness detection units arranged in the room, and perform program calculation on the light intensity of the region in which the personnel stay and a preset light value.

[0057] Based on the calculation result of the program calculation, a shutter piece 1 adjusting instruction is determined, and the servo motor 4351, the electromagnetic clutch assembly 436 and the activity motor 434 are controlled to act based on the shutter piece 1 adjusting instruction, the shutter piece 1 is controlled to change the included angle, the target region is adjusted to a preset light flux, and the illumination in the region is kept in a comfortable illumination range.

[0058] The overall use principle is as follows:

[0059] As Figures 2-6The main structure of the shutter curtain system of the present application includes the shutter curtain piece 1 which is arranged to be swingable at one end of the outer curtain piece 11 and the inner curtain piece 12 which are hinged to each other, and it is worth noting that the adsorption block 44 of the present application is arranged away from the hinge, and its position is adjusted according to the position of the arc-shaped rail 421, and when the outer curtain piece 11 or the inner curtain piece 12 swings to the end of either side of the arc-shaped rail 421, the end of the curtain piece is higher than the hinge point of the outer curtain piece 11 and the inner curtain piece 12, which is to ensure that there is no light leakage problem.

[0060] The adjusting mechanism 42 of the present application includes two sub-assemblies:

[0061] One is the permanent magnet piece 43, which is provided with an electromagnetic clutch assembly 436, and through the electromagnetic clutch assembly 436, the permanent magnet piece 43 can be linked with the rotating gear set 4352, so that the permanent magnet piece 43 can be driven to rotate by the servo motor 4351, and the rotation of the permanent magnet piece 43 can realize the movement of the sliding sleeve 431 along the arc-shaped rail 421, and when the adsorption block 44 and the permanent magnet block 433 are adsorbed, the outer curtain piece 11 or the inner curtain piece 12 of the shutter curtain piece 1 is turned over to realize the control and adjustment of the curtain piece.

[0062] The second is the driving matching structure of the permanent magnet block 433, as shown in the figure, Figure 4 The sliding sleeve 431 of the present application is provided with an inner telescopic hole 432, and the inner wall of the inner telescopic hole 432 is provided with an inner thread segment 4321, and the permanent magnet block 433 penetrating in the inner telescopic hole 432 is provided with a corresponding outer thread segment 4331, and the activity motor 434 fixed on the permanent magnet piece 43 can drive the permanent magnet block 433 to rotate forward and backward, and based on the cooperation of the inner thread segment 4321 and the outer thread segment 4331, the axial movement of the permanent magnet block 433 is realized, and it is worth noting that the permanent magnet block 433 and the main shaft of the activity motor 434 are matched by spline or polygon, and they are relatively movable in the axial direction and fixedly arranged in the circumferential direction, so that when the activity motor 434 is started to rotate forward and backward, the permanent magnet block 433 can be driven to move axially.

[0063] Through the above-mentioned two sub-assemblies, the shutter curtain piece 1 of the present application can be linked with the rotating gear set 4352 through the adjusting mechanism 42, and in the present application, the independent electromagnetic clutch assembly 436 is controlled by program to control each outer curtain piece 11 or inner curtain piece 12 independently, and through the on-off driving of the electromagnet 4371, the linkage or non-linkage of the two is realized, so as to realize the swing control of the shutter curtain piece 1, and thus the swing angle adjustment of the curtain piece is realized.

[0064] It is worth noting that the above-mentioned as Figure 4As shown, the diameter of the permanent magnet block 433 is smaller than that of the adsorption block 44, and the adsorption block 44 has a groove on the side opposite to the permanent magnet block 433. When the permanent magnet block 433 is fully extended, not only do the two adhere to each other, but the permanent magnet block 433 is located in the groove and forms a linkage when moving radially, thus preventing the adsorption block 44 from detaching from the permanent magnet block 433.

[0065] It is worth noting that if the overall width of the Venetian blind slat 1 is greater than the inner opening of the side rail frame 41, then the portion of the blind body located within the side rail frame 41 needs to be processed, such as... Figure 4 The notch 17 shown is designed to prevent the slats from being affected by the side rail frame 41 during the flipping process, thus preventing them from flipping over.

[0066] It is worth noting that the Venetian blind slat 1 of the present invention generally maintains a long-term linkage between the adsorption block 44 and the permanent magnet block 433. When the two become detached, the program can reset all the blinds, that is, all the blinds are detached and allowed to hang naturally so that all the outer blinds 11 and inner blinds 12 are at the bottom of the swing. Then the program controls all the permanent magnets 43 to rotate again so that the sliding sleeve 431 is aligned with the adsorption block 44. Subsequently, the active motor 434 is controlled to push the permanent magnet block 433 out to establish a connection with the adsorption block 44. If the linkage still fails, there is a problem, and the staff needs to manually repair it or the user can temporarily link it.

[0067] The invention is characterized by the ability of the adjustment mechanism 42 to rotate the outer slats 11 and inner slats 12 of the Venetian blind 1 relative to each other, and the ability of adjacent upper and lower Venetian blind slats 1 to be adjusted to different angle structures. The machine vision system detects, calculates, and locates the position of the person, and the brightness detection unit detects the brightness of the person's position and calculates it with the set brightness, taking into account the current time, the day-night cycle, and outdoor lighting. Finally, the power mechanism is controlled by the program to adjust the Venetian blind 1. When the light received by the person is too strong, the blinds are dimmed, and vice versa, to allow more external light to enter. Furthermore, when the external light is too dim and cannot meet the set brightness, multiple LED light beads 19 can be used to supplement the light. The brightness is adjusted through multiple means to improve the comfort of the person.

[0068] like Figure 7 The diagrams shown depict the changing structure of the curtains in the indoor setting. Under this change, light from both inside and outside cannot penetrate, keeping the room dark. This is suitable for adjusting the curtains when a darker indoor environment is needed. Figure 8The state of the shown louver sheet 1 is that when the indoor lighting is insufficient, the existing louver sheet 1 transmits light generally by adjusting the curtain sheet to be horizontal, but the sunlight is generally inclined to enter, and the wider the horizontal louver sheet 1 is, the more the light is affected by the direct light, so that the light that can enter is not much, and as Figure 8 The mirror structure is arranged on the upper surface of the inner curtain sheet 12, like a lens, when the sunlight from the outside is obliquely incident through the included angle of the two outer curtain sheets 11, the main rays of the light are as shown in the figure, the inner curtain sheet 12 is horizontal or has a little angle, so that the light on the curtain sheet is reflected upward, and the indoor brightness is improved.

[0069] As Figures 9-10 As shown, when the outdoor light is insufficient, the light can also be supplemented by the LED light beads 19, and there are two light supplementing modes, one is to simulate sunlight reflection, the LED light beads 19 of the outer curtain sheet 11 are reflected by the mirror surface of the inner curtain sheet 12, which not only can supplement light when the outdoor light is insufficient, but also generally cannot be seen by personnel looking straight at the window, avoiding the problem of dazzling, making the light more soft and comfortable, and the other use, Figure 9 The structure can be applied to some indoor rooms without windows, and the louver window curtain designed by the application can simulate the sunlight of the window, create a room with a window, and the simulation effect is excellent, and the included angle and the turning angle of the louver sheet 1 can realize manual and automatic adjustment of the light.

[0070] The automatic control method of the louver window curtain system includes a plurality of brightness detection units for detecting the indoor environment brightness, a camera dynamic capture unit 35 for detecting the activity of personnel, when there is personnel in the room, the device starts the camera dynamic capture unit 35 based on machine vision technology, locks the personnel, and tracks the area where the personnel are located, and the program is designed and divided in advance, the position coordinates of the personnel are calculated, the signal is sent to the brightness detection unit of the corresponding coordinate area, the brightness of the current area is fed back to the electric control system 3 for program operation, the difference between the suitable light setting under the current condition is matched, then the adjustment mode is further calculated, and the plurality of power elements are controlled through the adjustment instruction, so that the all outer curtain sheets 11 and inner curtain sheets 12 of the louver sheet 1 are controlled to swing, and the LED light beads 19 are started to supplement light according to the actual demand, so that the brightness of the position where the personnel are located is adjusted to the set value as much as possible, and the brightness demand is met.

[0071] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
