The present application claims priority to Korean Patent Application No. 10-2019-0107376, filed Aug. 30, 2019, the entire contents of which is incorporated herein for all purposes by this reference.
The present invention relates to a wall landscaping system creating a vertical garden on interior and exterior walls of a structure to improve global warming measures and perform fine dust purification, as well as reduce cooling and heating energy using a wall greening technology of carbonized cork which is a material for internal and external combustion, soundproofing, and insulation. More particularly, the present invention relates to a wall landscaping system that facilitates the growth management of plants and has an intelligent air cleaning function creating an optimal environment according to the surrounding environment and an advertisement function implementing letters or pictures with plants created on the wall, by applying a watering system that automatically supplies water at a predetermined interval for each plant and a monitoring system that automatically analyzes and announces the growth status of the plant.
Wall landscaping refers to a method of covering artificially constructed structures, such as walls, fences, soundproof walls, concrete retaining walls, and piers, with plants and is used to build indoor and outdoor nature-friendly structures such as public institutions, companies, and schools.
In other words, the wall landscaping is a nature-friendly interior design that combines the art of painting and sculpture, the natural elements that make use of the charm of leaves and flowers, the artificial element of a horticultural environment, and the resulting aesthetic and landscape element. Such wall landscaping has other effects such as air purification and noise reduction.
According to the Korean Ministry of Land, Transport, and Maritime Affairs (2009-905), it says that “wall greening is defined as planting or covering all or a part of a wall of a building or structure with plants”, and green walls, plant walls, eco-walls, vertical greening, and vertical gardens are used in the same sense as wall greening.
Wall greening refers to covering the walls of buildings, walls of structures such as fences surrounding buildings, retaining walls of roads, walls of civil structures such as banks of banks and embankments, and the facades of fairs, exhibitions, and venues, with plants.
In addition to rooftop greening, wall greening allows three-dimensional greening of buildings and structures that are artificially constructed in cities with insufficient green spaces, thereby enabling formation of urban ecosystems and creation of a pleasant environment. It is possible to make people feel comfort and abundance in the city by expanding the space where creatures can live in the inorganic urban space and increasing the greening that enables people to come into contact with nature.
In addition, there are advantages that a heat island phenomenon of the city is reduced, energy is reduced by the thermal insulation performance of a building, and the wall is protected by preventing cracking thereof. In addition, it is possible to increase the greening ratio since wall greening is artificial ground landscaping.
In addition, wall greening indoor literally means creating green space on the vertical surface of the building's interior space. In general, wall greening is greening on the outer wall of a structure or building that is installed outdoors, and indoor wall greening is a method of landscaping the indoor space using walls or pillars of the indoor space.
As examples of such wall landscape are disclosed in Korean Patent No. 10-1414933 (titled “Indoor and Outdoor Landscape Decoration”) and Korean Patent No. 10-1485824 (titled “Vertical Garden”)
According to the disclosed publications, the structures thereof are slightly different from each other, but a watering system automatically supplying water to plants according to a prescribed interval is provided, together with a cork board where plants are grown on the interior and exterior walls, thereby improving convenience of plant growth management.
Here, the maintenance of wall landscaping is most important. However, there is a problem that maintenance is often difficult in terms of manpower and cost. In other words, the proper supply of moisture is required to be supplied to the plants, as well as the plants has to be inevitably replaced when the plants are planted in a fresh state and then the plants wither or deteriorate during growth.
Therefore, when such problems occur, it is necessary to introduce a system that accurately measures and automatically determinate the growth state of the plants in order to solve the problems.

The waterproof cloth 13 preferably has a coal tar adhered thereto, the coal tar having a relatively low price and excellent waterproofness.
The root-resistant film 14 is a resin film having a thickness of 2.0 mm or more so as not to allow the plant root to penetrate therethrough, and is integrally attached to the rear surface of the plantation board 15. The root-resistant film 14 is formed of a resin material of any one of polyethylene, polypropylene, polyester, polyvinyl chloride, and urethane, and is preferably coated with an adhesive for adhesion on one surface thereof.
The plantation board 15 is a compressed plate with a waterproof, soundproofing, and insulating function and a thickness of 75 mm or more, to create a soil-like environment in which plants may grow, and one or more plantation boards 15 are attached to an outer surface of the root-resistant film 14. The plantation board 15 is formed of raw cork or carbonized cork or a mixture thereof, and is provided on one surface thereof with multiple planting holes 15a perforated with a diameter of 72 mm or more at intervals of 125 mm.
Here, the planting holes 15a may be formed to be inclined at 15°, toward the rear side, that is, downward as shown in
Although not shown in the drawing, watering holes are formed perpendicularly to the planting holes 15a, and the watering holes are filled with the good absorbent cotton fabric, thereby allowing water to be supplied to the root of the plant in a drop manner. The plantation board 15 may be equipped with a sensor that may measure the temperature and humidity and nutrients, and may be implemented so that a self-checking function is performed with information measured by the sensor.
Herein, it is preferable that the plantation board 15 is coated on the outer surface thereof with a flame-resistant layer 16 which blocks deformation or combustion due to heat as shown in
The phosphate ester is triaryl phosphate; ethyl phosphate is monoethyl phosphate; ethanol amine is triethanolamine (TEA); and ammonia is used at concentration of 60%.
Preferably, the flame-resistant layer 16 is composed of 7.2% by weight of borax, 0.8% by weight of boric acid, 1.0% by weight of phosphoric acid, 16% by weight of phosphate ester, 1.5% by weight of ethyl phosphate, 0.5% by weight of ammonia, and 5.0% by weight of ethanol amine.
The plantation board 15 coated with the flame-resistant layer 16 has an excellent fire resistance performance in which even when a flame is applied for 3 seconds with a torch spaced 10 cm from one surface, the flame disappears with the removal of the torch, thereby having fire resistance that satisfies both fire safety laws and the building laws.
In addition, the main body 10 may further comprise a reinforcing pipe 17 attached between the waterproof cloth 13 and the root-resistant film 14 to increase durability as shown in
The watering part 20 is a water supply facility that is disposed on an upper end of the main body 10 to automatically supply water to the plant, as shown in
The watering pipe 21 is a pipe having a diameter of 10 mm or more and is disposed above the top of the main body 10 in a traverse direction. The watering nozzle 22 is disposed downward toward the plantation board 15 below the watering pipe 21 and supply the water supplied to the watering pipe 21 in a drop manner. Here, the watering nozzle 22 may be arranged to match the longitudinal direction of the planting holes 15a arranged on the vegetation board 15.
The watering machine 25 is connected to the watering pipe 21 in communication therewith to automatically supply water at every predetermined interval of time. This watering machine 25 is configured with an on-off valve 25a, a water tank 25b, a pump 25c, a filter 25d, a pressure reducing valve 25e, and a timer 25f disposed in the enclosure as shown in

The water tank 25b is connected to a water flow passage to store a predetermined amount of water all the time. The water tank 25b has a detector built therein to measure the water level, thereby outputting the supply signal to the on-off valve 25a.
The pump 25c is disposed between a suction flow passage connected to the water tank 25b and a supply flow passage connected to the watering pipe 21 and is selectively operated according to a signal. That is, the pump 25c is driven in response to the signal of the timer 25f to pump the water stored in the water tank 25b into the watering pipe 21.
The filter 25d is attached to the suction flow path in a replaceable manner to filter water sucked by the pump 25c. It is preferable to use the filter 25d that has a combination of activated carbon and zeolite grains.
The pressure reducing valve 25e is disposed in the supply flow path that is between the pump 25c and the watering pipe 21 to adjust a flow rate of water being pumped. That is, the pressure reducing valve 25e adjusts the flow rate of water supplied to the watering pipe 21 to discharge the water of the watering nozzle 22 in a drop state.
The timer 25f interrupts the power supplied from the outside, and drives the pump 25c at a predetermined interval. The timer 25f is configured with a mechanical relay or an electronic relay, and it is preferable to configure a circuit breaker and a fuse together in order to prevent an electrical safety accident.
Herein, the watering machine 25 may include a cleaning module for automatically cleaning the filter 25d for filtering the water in the water tank 25b, in a periodical manner or according to contaminated state. Such a cleaning module may perform cleaning with high pressure water that is pumped in the opposite direction to the filtration, or cleaning via ionic activity caused by ultrasonic vibration or strong static electricity.
A detection unit 30 is disposed around the main body 10 as shown in
The color camera 31 is a general camera having RGB color, and preferably has a specification in which a high-definition image of HD level or higher is photographed as shown in
The depth camera 35 calculates the depth value of each pixel of an image, and is implemented with any one of stereo, time-of-flight (TOF), and structured light pattern methods, or a hybrid of a combination of thereof. Among them, it is preferable to use the TOF method which has depth recognition in units of mm, fast processing speed, good performance regardless of ambient brightness, and relatively low cost.
According to the TOF method, travel time information is obtained by measuring the delay or phase shift of the modulated infrared light signal for all pixels, and the depth of the subject (plant) is measured by measuring the delay of the optical signal obtained by reflecting the transmitted infrared light signal from the subject as shown in
For reference, the larger the distance to the subject, the smaller the size (projection height) of the plant, and herein the red is shown. In addition, the closer the distance to the subject, the larger the size of the plant, and herein blue in contrast to red is shown.
The controller 40 is a monitoring server that is connected to the detector 30 to store and analyze the photographed image as shown in
The controller 40 is provided with an image analysis application having a load module 41, an adjustment module 42, an arrangement module 43, a capture module 44, an analysis module 45, an output module 46, and a notification module 47 as shown in
The load module 41 makes a request for a photographing signal to the color camera 31 and the depth camera 35 to receive the color image and the depth image, respectively, as shown in
The adjustment module 42 sets the range of the main body 10 as the analysis area in the input color image and depth image. That is, X and Y coordinates are set according to the size of the plantation board 15 displayed on the image or specified in a drag-and-drop manner, as shown in
The arrangement module 43 extracts only the set analysis area to partition the boundary area for each planting part. That is, when the analysis area is set, the analysis area is extracted with the unnecessary images being excluded as shown in
The capture module 44 extracts and records images continuously input at a predetermined interval as a picture which is a single image frame, as shown in
The analysis module 45 determines the growth state of the plant using the average color and depth of the plant for each area of the recorded pictures, the output module 46 displays the growth state of each boundary area in the analyzed picture using management target color (red) capable of being distinguishable by a naked eye, and the notification module 47 notifies the manager of the growth state of the plant for each boundary area through the audible and visual information.
Herein, the controller 40 may also perform indoor and outdoor crime prevention, environmental condition monitoring, and resident health care, in addition to analysis of the growth state of the plant. In addition, the controller 40 is equipped with artificial intelligence to check the condition and operation of the watering machine 25.
Hereinafter, a detailed process of implementing the analysis module 45, the output module 46, and the notification module 47 will be described on the basis of examples.
That is, when the first recorded picture is analyzed, as shown in
Upon analyzing pictures recorded after 24 hours elapses from the first time, the plant growths in the zones 1-8, 2-8, and 2-9 are rapidly increased to be 64 mm, 56 mm, and 50 mm, respectively, which are determined to be normal. Herein, upon analyzing pictures recorded after 48 hours elapses from the first time, the plant growths in zones 1-8, 2-8, and 2-9 are 65 mm, 57 mm, and 58 mm, respectively, and thus are excluded from the management target, since initial growth is slow but the growth rate gradually increases.
However, considering pictures recorded at the first time and 24 hours after the first time, the plant in the zone 3-9 is found to grow relatively slowly from 65 mm to 67 mm. However, when 48 hours elapses from the first time, the plant in the zone 3-9 is 64 mm and thus is considered to be withered, whereby the plant in zone 3-9 is included in the control object.
The growth status of plant of each zone analyzed by this process is automatically generated as a report of numbers or pictures, and the generated report is output as the monitor and document, and also sent to the administrator's mobile terminal and e-mail address.
Herein, although not shown in a separate drawing, when it is determined that the average color of the plant for each zone is 50% or less compared to the average color of the plant, it is required to perform monitoring so that the manager may check the plants by a naked eye.
Hereinafter, the effectiveness of the wall landscaping system according to the present invention is considered through the experiment.
—Experiment Method—
The growth state of the plant obtained using the camera of the present invention and the growth state of the plant obtained by the actual measurer are compared in order to check the reliability.
—Experiment Conditions—
Glossy-leaf paper plant was planted on the plantation board of the same specifications and conditions, and the height exposed forward from the plantation board was measured every 24 hours from the 7th day after planting. The error in the actual measurement is ±5.0 mm.
—Experiment Result—
When analyzing the error according to the measured value as a experiment result, the growth state using the camera (A line) and the growth state using the actual measurer (B line) were indicated from 0.65% at a minimum to 35.05% at a maximum, with an average error rate of 7.3%, with reference to
That is, it may be appreciated that the measured value through the image analysis of the present invention and the actual measured value have an error rate of less than 10%, thereby ensuring the reliability of 90% or more to determine the growth state of the plant. Of course, when big data and artificial intelligence are introduced, it is expected to have the reliability of 95% or more.
Meanwhile, the wall landscaping system according to the present invention may further include an auxiliary part 50 which is configured with any one of an artificial intelligent air purifier 51 and a plant printing billboard 55, or a combination thereof, as shown in
The air purifier 51 is disposed at the top of the main body 10 to blow air filtered in a wet or dry manner toward the plant to double the self-cleaning and transpiration functions of the plant, thereby creating a more comfortable environment.
The air purifier 51 is equipped with artificial intelligence to monitor the surrounding environment, and to create a comfortable environment automatically or via an alarm according to the environment. That is, the air purifier 51 operates properly according to the ambient temperature, humidity, and illuminance, and also performs self-test periodically to prevent a failure.
In addition, the air purifier 51 may include a cleaning module for cleaning the filter filtering the air, periodically, or automatically according to the polluted state. The cleaning module performs high pressure cleaning using water received from the watering machine 25, or performs cleaning using a brush that rotates or flows in a predetermined direction.
In addition, the billboard 55 is attached to the main body 10 to install the mulching material 1 so that the embedded seeds guide information identified by colors of the plant grown as shown in
The seeds are embedded in the mulching material 1 through a seed preparation step S10, an area setting step S20, a seed designation step S30, a seed input step S40, a seed supply step S50, a seed embedment step S60 as shown in
First, the seed preparation step S10 is a step of selecting and preparing types of seeds embedded in the mulching material 1 and cultivated in the plant cultivation board, in which the user may select the type of the seed randomly or prepare the same among designated plants.
In the region setting step S20, a drawing requested by an advertiser is created in such a manner as to be divided or connected by predetermined areas or lines or dots using drawing creation software such as CAD or illustration. For example, in the case of creating a certain area of drawing, as the seeds are sown and grown, figures such as letters or pictures are distinguished by the areas.
The seed designation step S30 is a step of specifying the seeds to be embedded to each area for the areas set in the area setting step S20, in which the areas are distinguished by colors or symbols for each area, and seeds embedded in the mulching material 1 for each color are specified.
The seed input step S40 is a step of inputting the file created by specifying the seed for each area in the seed designation step S30, to the control unit 100 for controlling the seed embedment device A to be described later. For example, the step is performed so that the pattern file formed is input to the seed embedment device control unit 100 of the computer to read the area set by the controller 100 and control the seed embedment device A, so that the seeds specified according to the area are embedded in the mulching material 1.
In the seed supply step S50, the seed prepared in the seed preparation step S10 is stored in a seed storage hopper 2 provided in the seed embedment device A, so that the seed may be embedded in each area set in the mulching material 1, in which different seeds are included in at least one hopper 2 and thus supplied to the mulching material 1.
In the seed embedding step S60, the seeds are embedded for each area specified in the mulching material 1, in which the seeds specified for each area are supplied and then attached by controlling the seed on-off valve provided in the hopper 2 under the control of the control unit 100 to allow the seeds stored in the hopper to be embedded for each specified area. In addition, the seed embedment position is selected so that the advertiser may attach the seed at a certain interval in consideration of the type of the seed, whereby the operation of the seed embedment device A is controlled automatically. When the seed is embedded, the mulching material 1 is cut to fit the size of the billboard 55 and then attached to the billboard 55.
Here, the seed embedment device A is provided so that multiple hoppers 2 equipped with on-off valves are mounted on the horizontal axis 8, a plurality of longitudinal axes 9 is connected to the horizontal axis 8, in the lower part of the hopper 2 is provided a mulching material mounting base B on which the mulching material 1 is placed, and the control unit 100 for controlling the operation of the on-off valve and the movement position of the hopper is included, as shown in
For example, the process of embedding the seed to the mulching material 1 by the seed embedment device A will be described. When the area to which the seed is embedded in the mulching material 1 having a predetermined length is divided into five areas and different seeds are embedded to each area, the control unit 100 opens and closes the on-off valve of the first hopper 2a at regular intervals such that a first seed 3a is embedded in the first area 3.
When the first seed 3a stored in the first hopper 2a is supplied to the first area 3 by opening and closing the on-off valve, the hopper 2 is transferred left to right (or right to left), front to rear (or rear to front) of mulching material 1 through horizontal axis 8 and longitudinal axis 9 at a constant speed within the range of the first area 3, so that the first seed 3a may be embedded in the first area 3 of the mulching material 1 at regular intervals.
Subsequently, the control unit 100 opens and closes the on-off valve of the second hopper 2b at regular intervals such that a second seed 4a is embedded in the second area 4. When the second seed 4a stored in the second hopper 2b is supplied to the second area 4 by opening and closing the on-off valve, the hopper 2 is transferred at a constant speed within the range of the second area 4 from the left to the right, front to rear of the mulching material 1 through the horizontal axis 8 and the longitudinal axis 9, so that the second seed 4a is embedded in the second area 4 of the mulching material 1 at regular intervals.
Subsequently, the controller 100 opens and closes only the on-off valve of the fourth hopper 2d at regular intervals such that a fourth seed 6a is embedded in the fourth area 6. When the fourth seed 6a stored in the fourth hopper 2d is supplied to the fourth area 6 by opening and closing the on-off valve, the hopper 2 is transferred at a constant speed within the range of the fourth area 6 from the left to the right, front to rear of the mulching material 1 through the horizontal axis 8 and the longitudinal axis 9, so that the fourth seed 6a is embedded in the fourth area 6 of the mulching material 1 at regular intervals.
Subsequently, the controller 100 opens and closes only the on-off valve of the fifth hopper 2e at regular intervals such that a fifth seed 7a is embedded in the fifth area 7. When the fifth seed 7a stored in the fifth hopper 2e is supplied to the fifth area 7 by opening and closing the on-off valve, the hopper 2 is transferred at a constant speed within the range of the fifth area 7 from the left to the right, front to rear of the mulching material 1 through the horizontal axis 8 and the longitudinal axis 9, so that the fifth seed 7a is embedded in the fifth area 7 of the mulching material 1 at regular intervals.
In this way, since characters, pictures, and characters can be represented on the wall of the structure as the plant grows, it is possible to obtain promotional effects, as well as aesthetic beauty by combining various colors.
It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
