Description

Smart spray hydroponic system with bypass nutrient supply path

[0001] The present invention relates to a smart spray hydroponic system having a bypass type nutrient solution supply path.

[0002] Hydroponics is divided into pure water culture, where the roots are immersed only in a nutrient solution, and medium culture, where the roots are placed in a medium. Among these, pure hydroponics is a method of growing plants only in a nutrient solution without any substances to support the roots, and is further subdivided into deep water culture (DWC), nutrient film technique (NFT), aeroponics, and capillary culture.

[0003] Among these, spray hydroponics involves spraying nutrient solution onto the roots of the crop while they are suspended in the air. This method overcomes the oxygen deficiency problem in the roots that occurs in submerged hydroponics.

[0004] Therefore, spray hydroponics has the advantage of faster growth than other hydroponics methods because it does not cause oxygen deficiency and can be installed more densely in terms of space utilization.

[0005] Systems built for this type of spray hydroponics are being transformed into smart farms in line with technological advancements, and are being developed in ways that further enhance management convenience and cultivation efficiency.

[0006] In particular, various technologies are being developed to improve the convenience of managers' cultivation operations through the establishment of a smart spray hydroponic cultivation system, enable the acquisition and analysis of more precise cultivation-related information, and enable more efficient real-time response to various situations based on programs or algorithms.

[0007] In this regard, a prior art document for providing a hydroponic cultivation device with an automated nutrient solution supply process includes Korean Patent Publication No. 10-2544547 entitled “Smart hydroponic cultivation device with automated nutrient solution supply” (hereinafter referred to as “prior art”).

[0063] Accordingly, the sixth valve unit (160) and the second pressure sensing unit (165) are sequentially installed in the front second nutrient solution supply pipe (40), and the other end of the rear second nutrient solution supply pipe (75) is connected to the nutrient solution recovery pipe (50).

[0064] In addition, one end of the nutrient solution recovery pipe (50) is connected to the other end of the second nutrient solution supply pipe (75) on the rear side, and the other end is connected to the nutrient solution storage unit (120). On one side of the nutrient solution recovery pipe (50), a fourth pump unit (140) is installed that can control the movement speed of the nutrient solution that is used in the spray hydroponic cultivation unit (150) and then reused by controlling the pressure so that the nutrient solution is moved to the nutrient solution recovery pipe (50) and then recovered back to the nutrient solution storage unit (120).

[0065] In addition, the other end of the second nutrient solution supply pipe (75) on the rear side can be designed to have a configuration corresponding to the waste solution discharge pipe (39) and the ninth valve section (147) described above so that waste solution that cannot be reused after use in the spray hydroponic cultivation section (150) can be discharged to the outside.

[0066] The seventh valve section (180) is installed on one side of the bypass pipe (60, 65) and corresponds to a valve module that can control the supply amount of nutrient solution that moves through the bypass pipe (60, 65) by being pressurized and supplied through the second pump section (125) through opening and closing.

[0067] Here, the bypass pipe (60, 65) corresponds to a pipe that establishes a bypass-type nutrient solution supply path by connecting one end of the nutrient solution preparation pipe (20, 25) among the nutrient solution preparation pipes (20, 25) and the installation location of the second pump unit (125), and connecting the other end between the installation location of the first pressure sensing unit (145) among the first nutrient solution supply pipes (30, 35) and the other end of the first nutrient solution supply pipe (30, 35).

[0068] Accordingly, the bypass pipes (60, 65) are divided into a front bypass pipe (60) and a rear bypass pipe (65) based on the branching point so that multiple spray hydroponic cultivation units (150) are grouped into one group and each group is divided into groups, as shown in FIG. 1.

[0069] Additionally, a seventh valve section (180) is installed in the rear side bypass pipe (65).

[0070] The control unit (190) controls the operating status of the first valve unit (115) to the ninth valve unit (147) and the first pump unit (117) to the fourth pump unit (75) based on the detection information provided through the first pressure detection unit (145) and the second pressure detection unit (165).

[0071] To this end, the control unit (190) includes an information receiving unit (191), a first operation control unit (192), a second operation control unit (193), a third operation control unit (194), and an abnormal situation notification unit (195), as illustrated in FIG. 5.

[0072] First, the information receiving section (191) corresponds to a communication module that receives detection information provided from the first pressure detection section (145), the second pressure detection section (165), the first nutrient solution status detection section (127), and the second nutrient solution status detection section (128), and enables the generated notification information to be transmitted to a preset administrator terminal through the abnormal situation notification section (195).

[0073] In addition, according to the implementation, the information receiving section (191) also receives environmental detection information provided from a temperature detection section (not shown) and a humidity detection section (not shown).

[0074] Next, the first operation control section (192) performs control to open, close, or open only a certain percentage of at least one of the first valve section (115) to the ninth valve section (147) in order to perform the supply process and preparation process of the nutrient solution material, and performs control to determine whether or not at least one of the first pump section (117) to the fourth pump section (75) is driven and the driving level.

[0075] Specifically, as illustrated in FIG. 2, the first operation control section (192) first opens only the first valve section (115) and the second valve section (119), operates only the first pump section (117), and performs a supply process (W1) in which at least two nutrient solution materials are supplied for mixing from the at least two nutrient solution storage sections (110) to the at least one nutrient solution storage section (120) through the nutrient solution supply pipe (10, 15).

[0076] After the supply process (W1) of the nutrient solution material is completed, the first operation control part (192) opens only the second valve part (119) and the third valve part (129), and operates only the second pump part (125) to repeatedly move the partially mixed nutrient solution stored in at least one nutrient solution storage part (120) through the nutrient solution preparation pipe (20, 25) to form a completely mixed nutrient solution, thereby carrying out the preparation process (W2).

[0077] Here, the progress of the preparation process (W2) through the first operation control section (192) is linked to the first nutrient solution state detection section (127) and the second nutrient solution state detection section (128), and the operation states of the first valve section (115) to the ninth valve section (147) and the first pump section (117) to the fourth pump section (75) are controlled based on the detection information received through the information receiving section (191) from the first nutrient solution state detection section (127) and the second nutrient solution state detection section (128).

[0078] Specifically, as illustrated in FIG. 2, the first operation control section (192) analyzes the detection information provided to the information receiving section (191) from the first nutrient solution state detection section (127) and the second nutrient solution state detection section (128) according to a preset cycle, and repeatedly determines whether the detection information regarding the pH and electrical conductivity of the real-time nutrient solution corresponds to the nutrient solution standard state information regarding the preset standard pH and standard electrical conductivity.

[0079] As a result of this judgment, the preparation process (W2) through the first operation control section (192) is repeated until the detection information regarding the pH and electrical conductivity of the real-time nutrient solution provided to the information receiving section (191) from the first nutrient solution state detection section (127) and the second nutrient solution state detection section (128) matches the nutrient solution standard state information regarding the preset standard pH and standard electrical conductivity.

[0080] In addition, the second operation control section (193) controls the operating states of the first valve section (115) to the ninth valve section (147) and the first pump section (117) to the fourth pump section (75) based on the detection information received from the first pressure detection section (145) through the information receiving section (191).

[0081] Specifically, as illustrated in FIG. 3, the second operation control section (193) opens only the fourth valve section (135), the fifth valve section (140), and the sixth valve section (160) after the nutrient solution preparation process (W2) is completed, and operates only the third pump section (130), so that the nutrient solution in a completely mixed state stored in at least one nutrient solution storage section (120) is distributed and supplied to at least two or more spray hydroponic cultivation sections (150) through the first nutrient solution supply pipe (30, 35) and the second nutrient solution supply pipe (40, 45), thereby carrying out the first nutrient solution supply process (W3) according to the basic nutrient solution supply path.

[0082] The progress of the first nutrient solution supply process (W3) as described above is a basic nutrient solution supply form through the second operation control part (193), and in this process, the second operation control part (193) continuously analyzes the detection information received from the first pressure detection part (145) through the information receiving part (191) according to a preset cycle.

[0083] As a result, when the detection information provided from the first pressure detection unit (145) to the information receiving unit (191) during the first nutrient solution supply process (W3) is lower than the first supply pressure reference information regarding the preset reference supply pressure on the first nutrient solution supply pipe (30, 35), the second operation control unit (193) allows the second nutrient solution supply process (W4) to proceed alternatively according to the bypass type nutrient solution supply path.

[0084] Specifically, as illustrated in FIG. 4, the second operation control section (193) opens only the third valve section (129), the sixth valve section (160), and the seventh valve section (180), and operates only the second pump section (125), so that the completely mixed nutrient solution stored in at least one nutrient solution storage section (120) is distributed and supplied to at least two or more spray hydroponic cultivation sections (150) through the nutrient solution preparation pipe (20, 25), the bypass pipe (60, 65), and the second nutrient solution supply pipe (40), thereby allowing the second nutrient solution supply process (W4) to proceed in place of the first nutrient solution supply process (W3) according to the basic nutrient solution supply path.

[0085] Here, the detection information provided from the first pressure detection unit (145) to the information receiving unit (191) is lower than the first supply pressure reference information regarding the preset reference supply pressure on the first nutrient solution supply pipe (30, 35), which means that a defect has occurred in the operating status of at least one of the third pump unit (130), the fourth valve unit (135), and the fifth valve unit (140), or that a specific foreign substance filtered by the second filter unit (137) is causing a significant obstruction to the supply flow of the nutrient solution.

[0086] Accordingly, the first nutrient solution supply process (W3) according to the basic nutrient solution supply route is immediately stopped, and the second nutrient solution supply process (W4) according to the bypass nutrient solution supply route is immediately performed to prevent any disruption in performing spray hydroponics and thus problems in the growth of the cultivation target.

[0087] Furthermore, the second operation control section (193) is configured with a plurality of spray hydroponic cultivation units (150) based on environmental detection information regarding the temperature and humidity levels of the surrounding environment of each group, which is received through the information receiving section (191) from the temperature detection section (not shown) and the humidity detection section (not shown), and supplies the nutrient solution through the first nutrient solution supply process (W3) or the second nutrient solution supply process (W4) according to the cycle according to the temperature and humidity levels in accordance with the nutrient solution supply algorithm according to the preset temperature and humidity levels.

[0088] In addition, the third operation control section (194) controls the operating states of the first valve section (115) to the ninth valve section (147) and the first pump section (117) to the fourth pump section (75) based on the detection information received from the second pressure detection section (165) through the information receiving section (191).

[0089] Here, the third operation control section (194) continuously analyzes detection information received from the second pressure detection section (165) through the information receiving section (191) according to a preset cycle during the first nutrient solution supply process (W3) according to the basic nutrient solution supply path or the second nutrient solution supply process (W4) according to the bypass type nutrient solution supply path.

[0090] As a result, when the detection information provided from the second pressure detection unit (165) to the information receiving unit (191) during the first nutrient solution supply process (W3) according to the basic nutrient solution supply route or the second nutrient solution supply process (W4) according to the bypass type nutrient solution supply route is lower than the second supply pressure reference information regarding the standard supply pressure on the preset second nutrient solution supply pipe (40), the third operation control unit (194) controls the opening and closing degree of the sixth valve unit (160) differently for each installed second nutrient solution supply pipe (40) so that a supply control process is simultaneously performed so that more nutrient solution can flow in a specific second nutrient solution supply pipe (40).

[0091] In a relief manner, the third operation control section (194) controls the opening / closing degree of the sixth valve section (160) connected to the second nutrient solution supply pipe (40) in which the second pressure detection section (165) that generates detection information detected as a lower value than the second supply pressure reference information is installed, to be different from the opening / closing degree of the sixth valve section (160) connected to the remaining second nutrient solution supply pipe (40), so that the supply control process is performed simultaneously with the first nutrient solution supply process (W3) according to the basic nutrient solution supply path or the second nutrient solution supply process (W4) according to the bypass nutrient solution supply path.

[0092] For example, the sixth valve unit (160) connected to the second nutrient solution supply pipe (40) in which the second pressure detection unit (165) is installed, which generates detection information detected at a lower value than the second supply pressure reference information, opens at a greater rate than the sixth valve unit (160) connected to the remaining second nutrient solution supply pipes (40), so that the amount of nutrient solution moved through the second nutrient solution supply pipe (40) in which the second pressure detection unit (165) is installed, which generates detection information detected at a lower value than the second supply pressure reference information, can be relatively increased, thereby maintaining an overall balanced supply.

[0093] As another example, the sixth valve unit (160) connected to the second nutrient solution supply pipe (40) in which the second pressure detection unit (165) that generated the detection information detected as a lower value than the second supply pressure reference information is installed may be temporarily closed to prevent the supply of nutrient solution to the connected spray hydroponic cultivation unit (150) for a certain period of time until repair.

[0094] Lastly, the abnormal situation notification part (195) is activated when the second nutrient solution supply process starts through the second operation control part (193) and generates first abnormal situation notification information notifying that an abnormal situation has occurred on the first nutrient solution supply pipe (30, 35) and transmits the information to a preset administrator terminal.

[0095] In addition, the situation notification section (195) is activated when the supply control process begins through the third operation control section (194) to generate second abnormal situation notification information that notifies that an abnormal situation has occurred on the second nutrient solution supply pipe (40) and transmits the information to a preset administrator terminal.

[0096] In connection with this, the manager who has received the first abnormal situation notification information or the second abnormal situation notification information through the situation notification section (195) immediately performs direct repair or replacement work on the part where the abnormal situation occurred while the situation response through the smart spray hydroponic system (100) is being automated.

[0097] Through this process, when the direct repair or replacement work by the administrator is completed, a response completion notification information is generated to notify that the response to the specific first abnormal situation notification information or second abnormal situation notification information provided using the administrator terminal has been completed and is transmitted to the control unit (190).

[0098] Accordingly, when the response completion notification information according to the first abnormal situation notification information is received through the information receiving section (191), the second operation control section (193) allows the second nutrient solution supply process (W4) according to the bypass type nutrient solution supply path to be replaced by the first nutrient solution supply process (W3) according to the basic nutrient solution supply path.

[0099] In addition, when the response completion notification information according to the second abnormal situation notification information is received through the information receiving section (191), the third operation control section (194) controls so that the sixth valve section (160) connected to all second nutrient solution supply pipes (40) can be opened at the same rate.
