1 , 2A and 2B , the water quality measuring apparatus 100 includes a water flow former 110 and a water quality sensor 120 .

First, the water flow generator 110 is for forming a water flow by inflow and outflow of water, and may be composed of a bracket 111 , a fan 112 , and a sieve 113 .

The bracket 111 is provided with a water passage through which water passes. In the drawings, the bracket 111 is provided in a circular pipe shape to facilitate water flow formation so that the water channel is formed in a straight line, but the present invention is not limited thereto. The shape of the water channel can be formed in a curved shape as needed, and the shape of the bracket 111 is also applicable to any shape through which water can pass.

In addition, the bracket may be formed to be porous, and may be provided to allow water to flow therethrough.

The fan 112 functions to introduce water into the waterway and to discharge it to the outside. The fan 112 may be in the form of a screw fan, but is not limited thereto, and any shape capable of introducing water into a water channel is applicable.

The operating speed of the fan 112 may be changed according to a water level measurement sensor value to be described later, and may be selected from preset values through an experiment. For example, in the case of the fan 112 installed in an area where the water level is high, the operating speed may be controlled relatively faster than in the area where the water level is low. As the operating speed of the fan 112 is controlled according to the water level, there is an advantage in that the measured value of the water quality can be accurately measured regardless of the water level.

The sieve 113 is disposed at the inlet portion of the water passage through which the water flows so that foreign substances do not flow into the water passage. The arrangement position of the strainer 113 is not limited thereto, and may be arranged in various forms.

In particular, when the bracket 111 is formed to be porous, the strainer 113 may be disposed to surround the entire exterior of the bracket 111 . For this reason, when water flows into the pores formed in the bracket 111 , it is possible to prevent foreign substances from flowing into the inside of the bracket 111 .

The sieve net 113 may be formed in the same form as a mesh net, but is not limited thereto and may be provided in various forms.

As the water flow generator 110 includes the fan 112, the inflow and discharge of water becomes easier by the operation of the fan 112, and as the sieve 113 is provided in the water flow generator 110, the floats in the plantation are There is an advantage in that it is possible to minimize the measurement error of the water quality sensor 120 by preventing the inflow into the inside of the water flow former 110 .

Subsequently, the water quality sensor 120 is disposed inside the water flow generator 110 to measure water quality data, and may include at least one of a temperature sensor, an EC sensor, and a pH sensor.

A plurality of water quality sensors 120 may be provided, and the arrangement position is not limited to the drawings. For example, it may be installed on the inner wall of the waterway to measure water quality data of water passing through the waterway.

The water quality sensor 120 may be sealed with silicone or the like so that the inside of the sensor is not exposed to water.

When the water quality measuring device of the present invention described above is used, since the water quality sensor is mounted inside the water flow former, it is possible to prevent damage from external environmental factors or interference with measurement.

In addition, as the water flow generator forms the water flow, the water quality environment in the hydroponic cultivation area such as paddy fields where water is not circulated and stagnant is circulated without stagnation, thereby forming and maintaining an equilibrium state, thereby reducing the deviation of the measurement value and providing an accurate water quality environment. There are measurable benefits.

In the above, the configuration of the water quality measuring device was examined. Hereinafter, a smart farm monitoring system including the above-described water quality measurement device will be described.

Hereinafter, content overlapping with those described with reference to FIGS. 1 and 2 will be omitted or simply described.

3 shows a smart farm monitoring system according to an embodiment of the present invention.

Referring to FIG. 3 , the smart farm monitoring system 1 may be provided to include a water quality measuring device 100 , a water level measuring device 200 , a plantation management server 50 , and a water supply device 300 . .

First, the water quality measuring apparatus 100 functions to measure the water quality of the cultivation area 10 as described above. The water quality measuring device 100 includes a water quality sensor, and measures water temperature, electrical conductivity (EC), and pH of the cultivation area 10 . The measured water quality data is transmitted to the cultivated land 10 management server 50 to be described later.

Subsequently, the water level measuring device 200 measures the water level of the cultivated land 10 and transmits the measured water level to the cultivated land 10 management server 50 .

The water level measuring device 200 includes a main body having an upper and lower opening and an inner space; a cover covering the upper part of the body; and a water level sensor disposed on the upper end of the inner wall of the body to measure the water level.

Conventionally, as the upper portion of the water level measuring device 200 is formed in an open cylindrical shape, it has a structure that is easy to be affected by environmental factors. there has been In addition, even when the water level sensor is installed outside the water level measuring device 200 , there is a problem in that the leaf of a crop touches the water level sensor or blocks the water surface, thereby preventing accurate water level measurement.

In order to solve this problem, the water level measuring device 200 of the present invention is provided with a cover on the main body so that interference with external environmental factors does not occur, and the upper part is provided in a closed form, but only a part of the upper part is opened.

According to one embodiment, the diameter of the main body of the water level measuring device may be provided to be smaller than the arrangement interval of the crop. Accordingly, there is an advantage in that it is possible to prevent a part of the crop from being swept into the inside of the water level measurement device to prevent the measurement of the water level or generate an error in the measurement value. Accordingly, it is possible to accurately measure the water level without being affected by external environmental factors.

At this time, the water level sensor is disposed on the upper end of the inner wall of the body, and by measuring the distance from the water surface using an infrared distance sensor, it may be provided to measure the water level of the cultivation area (10). That is, the method of deriving the water level by measuring the distance between the water surface and the sensor by providing the infrared rays emitted by the infrared distance sensor toward the water surface may be applied. The shape of the water level sensor is not limited to the infrared distance sensor, and various types of sensors such as an ultrasonic sensor or a floating sensor may be applied.

Subsequently, the plantation 10 management server 50 receives measurement data from the water quality measurement device 100 and the water level measurement device 200 to control the supply of water and nutrient solution, and includes the following configurations may be provided to do so.

The receiver 51 receives water quality data from the water quality measuring device 100 and water level data from the water level measuring device 200 .

The pH control unit 52 serves to derive an appropriate pH value of irrigation water to be supplied to the cultivation area 10 based on the pH value of the water quality data, and transmits a pH control signal to the water supply device 300 to be described later. do.

The supply control unit 53 functions to transmit a water supply signal to the water supply device 300 based on the water level data.

Subsequently, the water supply device 300 receives a water supply signal from the supply control unit 53 of the cultivation area 10 management server 50 , and controls the operation of the pump to automatically supply water to the cultivation area 10 . carry out

For example, the water supply device 300 may be provided to control the water supply by turning on or off the power of the pump. At this time, when the desired water level is reached by applying the floating sensor together, the operation of the water supply device 300 may be controlled to automatically stop by shutting off the power of the pump.

At this time, when the water supply device 300 supplies water, a specific pH is applied to the irrigation water supplied to the cultivation area 10 according to the pH control signal received from the pH control unit 52 of the cultivation site 10 management server. Eggplant may be controlled to adjust the pH of the culture medium (10) water quality by adding a culture solution. In general, an environment in which a pH value of about 5.5 to 6.0 is maintained is suitable for growing crops.

Specifically, when the pH of the soil of the cultivation area 10 is alkaline, irrigation water diluted with an acidic culture solution such as sulfuric acid is supplied to the cultivation area 10 to control the water supply device 300 to maintain a specific pH range. can

First, the soil data received to the receiving unit 51 of the plantation 10 management server 50 is transmitted to the pH adjusting unit 52, and based on the soil pH value among the soil data, the amount of irrigation supplied to the plantation area 10 is An appropriate pH value is derived. When the derived pH value is transmitted to the water supply device 300 of the cultivation area 10 , the water supply device 300 supplies irrigation water having the corresponding pH value to the cultivation area 10 .

For example, in the case of an area having a desert dry climate (eg, Dubai), where it is difficult to cultivate crops as the soil itself is alkaline and the alkali is maintained even in rainy weather, if the present invention is applied, the irrigation water supplied to the plantation is acidic. By mixing and supplying the culture medium, it is possible to maintain an appropriate pH value.

In an embodiment of the present invention, measurement data measured from the sensors may be stored in a storage DB.

The storage DB stores smart farm data received from the smart farm data processing server.

The storage DB may be provided inside the smart farm data processing server or separately provided outside the server, and the form of the provision is not limited thereto.

For example, the storage DB is a relational database management system (RDBMS) such as Oracle, Infomix, Sybase, DB2, or MySQL, or a non-relational database management system (NoSQL), Gemston ), Orion, O2, etc. using an object-oriented database management system (OODBMS) may be implemented for the purpose of the present application, and may have appropriate fields to achieve its function.

In the storage DB, smart farm data accumulated in real time may be accumulated and stored according to time series. In addition, in the storage DB, smart farm data according to crop items and objects is converted into a database for each field and accumulated and stored, so that big data can be built.

In an embodiment, the smart farm monitoring system of the present invention may be provided to further include a manager terminal 70 connected to enable communication with the plantation management server.

The manager terminal 70 is equipped with a normal web browser, and may be provided as any type of wired/wireless communication device capable of accessing the plantation management server 50 and using various web services.

Accordingly, it is possible to monitor the environment such as water quality and soil of the plantation 10 on the manager terminal 70, and to be implemented to enable manual control of the environment control device including the water supply device 300 provided in the plantation. can

Further, in an embodiment, the smart farm monitoring system may be provided to further include a root zone sensor that is disposed inside the soil of the cultivation area, and measures the temperature, moisture content, and EC of the soil.

4 shows a smart farm monitoring system according to another embodiment of the present invention, and FIGS. 5A and 5B show examples of actual use of the root zone sensor according to an embodiment of the present invention. Hereinafter, content overlapping with those described with reference to FIGS. 1 to 3 will be omitted or simply described.

4, 5A, and 5B, the smart farm monitoring system 1 according to an embodiment of the present invention includes a water quality measuring device 100, a root zone sensor 400, a plantation management server 50, and It may be provided to include a water supply device (300).

The rhizosphere sensor 400 is for measuring the soil quality of the rhizome, which means the vicinity of where the roots of plants grow, is provided to be inserted in the depth direction into the interior of the soil. It can be waterproofed with a silicone finish or taping to prevent leaks.

A plurality of the root zone sensor 400 may be provided according to the area of the soil. The soil can be divided into a plurality of zones and sensor can be measured and monitored, and the zones can be provided to be divided into mounds such as weirs and farm fields.

In addition, the root zone sensor 400 may be provided to measure the soil quality of topsoil, medium soil, and subsoil according to a depth inserted into the soil. For example, topsoil refers to a soil surface, medium soil may be soil having a depth of about 100 mm from topsoil, and subsoil may be soil having a depth of about 100 mm to about 200 mm.

The root zone sensor 400 is disposed in each of topsoil, medium soil, and subsoil of the soil to measure soil data including temperature, moisture content, and electrical conductivity (EC) of the soil.

In particular, in the case of the electrical conductivity (EC) of the soil, since it is a standard indicating the content of nutrients contained in the soil, if it rises above a certain level, the osmotic pressure in the soil increases, and the crop closes the stomata and stops water absorption. Growth is slow and yields are reduced. Therefore, monitoring is essential so that the electrical conductivity maintains a constant value.

The soil data measured by the root zone sensor 400 is transmitted to the above-described plantation management server 50 like the water quality data, and may be implemented to control the characteristics of the soil based on the data.

For example, when the EC of the soil of the cultivation area is out of a preset range, the EC of the soil of the cultivation area may be adjusted by adjusting the components of the solid fertilizer.

In an embodiment, the plantation management server 50 of the present invention transmits fertilizer information to the manager terminal to have a preset EC appropriate value for each crop based on the EC value received from the root zone sensor 400 EC control unit It may be provided to further include (54).

In addition, the EC controller 54 may be provided to derive a suitable EC control value by receiving the water quality EC value received from the water quality measurement sensor 100 in addition to the soil EC value.

In this case, the EC control unit 54 may derive an EC control value based on a preset appropriate EC value for each crop, and provides fertilizer information including ingredients and supply amount of fertilizer to satisfy the derived EC control value to the manager terminal. may be provided to be transmitted to

The manager terminal may control the water quality of the plantation and the EC values of the soil to satisfy preset values by processing the corresponding fertilizer in the plantation based on the fertilizer information provided from the EC controller 54 .

The smart farm monitoring system of the present invention as described above can be easily used for cultivation of crops including rice grown in paddy fields or hydroponics cultivated by confining water.

In particular, the present invention has an advantage in that crops can be grown even in desertified plantations. Unlike Korean paddy fields made of mud, Dubai's soil has the characteristics of sandy soil, and the drainage is very severe, so there has been a problem that irrigation water must be continuously supplied to the cultivated land.

The smart farm monitoring system of the present invention is to solve the above problems, and can be most suitably applied to cultivate cultivated rice such as tropical japonica in a cultivated land of sandy characteristics such as Dubai. The present invention is not limited to the above-described example, and in addition, it may be used in a growing environment of various crops using hydroponics.

The smart farm monitoring system described above may be implemented in the following form.

6 shows a smart farm monitoring system according to another embodiment of the present invention.

Referring to FIG. 6 , the plantation management server 50 may be provided in the form of a cloud server 50 to be able to communicate with the manager terminal 70 .

The cloud server 50 may be provided in various forms, such as Infrastructure as Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

The manager terminal 70 is a terminal possessed by the manager to manage the smart farm monitoring system 1, and is connected to the cloud server 50 to enable data transmission and reception by cell phone, PDA, PC, laptop, tablet PC, etc. It may be a device with functions and output functions.

If the cloud server 50 is utilized, the plantation management server 50 of the present invention can be implemented to be connected to a plurality of plantations 10 . Accordingly, it is possible to simultaneously monitor the environment of a plurality of cultivation fields 10 from one manager terminal 70 , and it is possible to remotely control an environment control device including a water supply device provided in the cultivation field.

The cloud server 50 may be connected to a storage DB. Accordingly, since the cloud server 50 can load appropriate data from the storage DB and transmit it to the manager terminal 70 , there is an effect that the data processing speed and efficiency can be further increased. In addition, the cloud server 50 may be provided to store and store the data received from the cultivation area 10 accumulatively.

For example, water quality measurement data, water level measurement data, soil quality measurement data, and crop image data received from the cultivation area 10 may be accumulated and stored in the storage DB.

In an embodiment, the smart farm monitoring system of the present invention may be provided to further include a camera.

The camera functions to photograph the cultivated land, and a plurality of cameras may be arranged as needed for each area of the plantation. The photo or image taken through the camera may be transmitted to the farmland management server in real time and provided so that it can be monitored through the manager terminal.

In this case, the camera may be provided as a CCTV or a PTZ network camera with Pan, Tilt, and Zoom functions, and may be provided so that rotation and enlargement of images can be performed remotely and in real time.

7A to 7D are examples of screens provided to an administrator terminal according to an embodiment of the present invention.

7A to 7D , water quality data measured from a water quality measuring device and soil data measured from a root zone sensor together with crop image data including photos or images taken through the above-described camera are displayed on the manager terminal. can be provided.

On the screen provided by the manager terminal, water quality data and soil data of topsoil, medium soil, and subsoil for each area of the cultivation area are displayed. The water quality data may include an irrigation water temperature, an irrigation water EC, and an irrigation water pH value, and the soil data may include a soil temperature, a soil moisture content, and a soil EC value.

At this time, since the water quality sensor can be installed only on topsoil to which irrigation water is supplied, only the measured values of the topsoil are transmitted to the server. Accordingly, in the case of topsoil, the water quality sensor value and the rhizosphere sensor value may be displayed together, and in the case of medium soil and subsoil, since there is no water quality sensor measurement value, only the rhizosphere sensor value may be displayed.

As described above, in the smart farm monitoring system of the present invention, as the farmland management server and the manager terminal are provided to be connectable, there is an advantage in that the growth and growth of crops can be monitored in real time without the manager directly visiting the farmland. .

In particular, if the smart farm monitoring system of the present invention is used, there is an advantage in that soil and water quality data according to the depth of the soil for each cultivation area can be monitored in real time.

Furthermore, in an embodiment, the smart farm monitoring system of the present invention may be implemented to generate sensor arrangement information for each soil area to control the arrangement position and the number of arrangement of sensors.

For example, referring back to FIG. 4 , the plantation management server 50 according to an embodiment of the present invention may further include a sensor arrangement information table generating unit 55 . The sensor arrangement information table generating unit 55 may generate a table for the sensor arrangement information for each area in consideration of topography (slope, altitude) and water level and transmit it to the manager terminal 70 .

8 is an example showing the topography and sensor layout for each area generated by the sensor arrangement information table generation unit of the plantation management server according to an embodiment of the present invention.

Referring to FIG. 8 , it can be seen that the number of sensors arranged in each zone is different. This is set in consideration of the topography (slope, altitude) and water level for each area.

Table 1 below shows the number of sensor arrangements according to the topography and water level for each area of FIG. 8 .

plantation terrain Water level
(cm) water quality Soil (root zone) evaluation slope Altitude topsoil topsoil baryta subsoil Key Zone 1 flat lowness 8.0 One One fitness Key Zone 2 slope height 6.5 One One One security concentration zone slope lowness 10 One One One One fitness

Referring to FIG. 8 and Table 1, in the case of the central zone 1, it can be seen that the terrain is flat and the water level is high. Accordingly, since the movement of water is relatively free compared to the slope, it is easy to maintain the equilibrium state of water quality, so the number of sensors is arranged the least. On the other hand, in the case of the central zone 2, since the terrain has a high slope, the flow of irrigation water is not free, so the measurement value of each water quality sensor may be different depending on the arrangement location. Therefore, it is necessary to provide a plurality of sensors compared to the flat area, and the distance between the sensors according to the altitude can be adjusted together.

In addition, by further considering the sensor measurement values according to the sensor arrangement positions for each zone, the number and spacing of the sensors for topsoil, midsoil, and subsoil of the water quality sensor and the root zone sensor may be controlled.

For example, in the case of an area where the same sensor value is measured, the number of batches of sensors is reduced, and in the case of a zone where there is a difference in the measured values of sensors by location, the number of batches of sensors is supplemented and the arrangement interval is narrowed. can do.

In addition, it is also possible to control the sensor arrangement based on the drainage degree and flow rate according to soil characteristics (mud, sand, composition).

Depending on the region, terrain having the same or very similar soil quality may exist as a whole, and in contrast, regions with a mixture of various soils may exist. can

For example, it is easy to maintain the equilibrium state of water quality after supply of irrigation water because continuous supply of irrigation water is unnecessary in the cultivated land with muddy soil as in Korea because water loss is not large.

On the other hand, in the case of a cultivated land having desertified sandy soil such as Dubai, water loss is very severe due to the nature of the soil, so irrigation water must be continuously supplied. For this purpose, the sprinkler is operated. Because the flow of water around the sprinkler is fast, it is difficult to grow crops in the vicinity, and there may be a difference in the sensor measurement value between the vicinity of the sprinkler and the area far away from the sprinkler. there is. That is, there is a problem in that it is difficult to maintain the water quality of the plantation in an equilibrium state.

Therefore, in a zone with a high deviation, such as the corresponding zone, it is possible to compensate for the arrangement number of sensors and to narrow the arrangement interval to control accurate sensor measurement.

In this way, using the smart farm monitoring system of the present invention described above, it is possible to control the number and arrangement of sensors for each area based on the measured values of the water quality sensor and the root zone sensor arranged for each area. For this reason, there is an advantage in that it is possible to minimize unnecessary sensor arrangement, derive the most suitable sensor arrangement for the topography and environmental requirements of the cultivated area, and improve the measurement efficiency of the sensor.

In the above, the configuration of a smart farm monitoring system according to an embodiment of the present invention has been reviewed. Hereinafter, a smart farm monitoring method according to an embodiment of the present invention will be described.

Hereinafter, in the process of explaining each step, content overlapping with those described with reference to FIGS. 1 to 3 will be omitted or simply described, and FIGS. 1 to 3 will be referred to together to help the understanding of the description. In addition, unless otherwise stated, it is assumed that the subject performing each step is the plantation management server shown in FIGS. 1 to 3 .

Thereafter, the step of supplying water to the plantation by the water supply device is performed.

Thereafter, the manager terminal communicates with the plantation management server, and the step of monitoring the environment of the plantation is performed.

Furthermore, according to an embodiment of the present invention, a computer-readable recording medium including a program for executing the above-described smart farm data processing method may be implemented.
