1 is a block diagram illustrating functions of a greenhouse monitoring system according to an embodiment of the present invention.

As shown in FIG. 1, the greenhouse monitoring system according to the embodiment of the present invention not only monitors the growth of plants grown in the greenhouse, but also monitors the degree of deformation of the greenhouse ceiling. Through this, it is possible to detect growth environment information including information such as temperature, humidity, solar radiation amount, atmospheric condition, and plant growth image inside the greenhouse where the plant is grown, and provide it to the portable terminal. Also, by monitoring the deformation of a greenhouse ceiling where plants are grown, the risk of greenhouse collapse due to external weather conditions can be detected in advance.

Specifically, the greenhouse monitoring system may include a sensing unit 100, a control unit 200, and a portable terminal 300.

The sensing unit 100 can detect the growth environment information including the temperature, humidity, solar radiation amount, or atmospheric state in which the plant is grown, and can shoot an image.

In particular, the sensing unit 100 can be mounted on a moving body and can move along a rail installed in a greenhouse. The description will be made again with reference to Figs. 2 to 6.

The portable terminal 300 may include a portable terminal using a mobile communication network such as a smart phone or a mobile phone, or a portable terminal equipped with a data communication module such as a WiFi module.

The portable terminal 300 may be connected to the controller 200 through wireless communication to receive plant growth environment information or image data in real time. In addition, the portable terminal 300 can receive the alarm signal provided by the control unit 200.

The control unit 200 may store data input from the sensing unit 100 and may control the greenhouse using data. The control unit 200 may generate image data by matching the photographing position of the camera module included in the sensing unit 100 with the photographing image.

The control unit 200 receives the deformation of the greenhouse ceiling inputted from the sensing unit 100, compares the deformation with the reference value stored in advance, and generates an alarm when the comparison result is out of the reference value.

The control unit 200 can control the switch a, the water pump b, the fluid supplier c, and the like using data input from the sensing unit 100. The controller 200 may control the peripheral device by generating a signal to open / close the window through the switch (a) or to activate the cold / warm fan when the temperature input from the sensing unit 100 does not match the set temperature . In addition, when the humidity input from the sensing unit 100 does not match the set humidity, the control unit 200 can generate and operate a signal for operating the irrigation pump b. The controller 200 may compare the luminous intensity of the incident light input from the sensing unit 100 with the luminous intensity thus set so as to enable automatic control such as generating a signal for activating the light-shielding film when the luminous intensity is out of the setting range.

The control unit 200 may convert the image input from the sensing unit 100 and provide the converted image to the portable terminal 300. At this time, the control unit 200 compares the input image with the stored image to determine the state of the plant, and can provide the portable terminal 300 with the state of the plant.

The controller 200 may be implemented as a control box or a server.

As described above, the greenhouse monitoring system according to the embodiment of the present invention can automatically control the plant growth environment, and can confirm the state of plants grown in the photographed image.

Hereinafter, each of the components will be described in more detail with reference to FIGS. 2 to 8. FIG.

2 is a block diagram showing each configuration of the sensing unit shown in FIG.

Referring to FIG. 2, the apparatus may include a growth environment measurement sensor module 110, a camera module 120, a wireless communication module 130, a micro control unit 140, and a strain measurement sensor module 150.

Specifically, the growth environment measurement sensor module 110 may include at least one of a temperature sensor, a humidity sensor, a brightness sensor, and a carbon dioxide measurement sensor. The growth environment measurement sensor module 110 can measure temperature, humidity, solar radiation amount, carbon dioxide concentration, and the like among factors that may affect plant growth in real time and transmit it to the control unit 200.

The temperature sensor may be a thermocouple, a temperature measuring resistor, a thermistor, or a metallic thermometer. The temperature sensor may be a sensor using an NQR (nuclear quadrupole name), an ultrasonic wave, or an optical fiber.

The humidity sensor may be a sensor used for detecting humidity by using various phenomena related to moisture in the air (physical / chemical phenomenon). The humidity sensor may be a sensor using a change in electrical resistance or capacitance caused by absorption by a porous ceramics or a polymer membrane or a sensor for sensing humidity using a change in the resonance frequency of the vibrator due to a change in weight of an absorbing material provided in the vibrator .

A light intensity sensor is a sensor that measures the amount of light that is input, and a light intensity sensor may be a photoconductive sensor in which electricity flows when light is incident.

The carbon dioxide measuring sensor is a sensor for measuring the concentration of carbon dioxide in the air. It is possible to determine whether the carbon dioxide measuring sensor maintains the optimum carbon dioxide concentration at which the photosynthesis of the plant can be smoothly performed.

The camera module 120 captures a cultivation environment image. The camera module 120 may be a PTZ (Pan & Tilt & Zoom) camera, and may include a forward surveillance camera including left, right, up and down, and zoom functions.

The strain measurement sensor module 150 measures the height change of the greenhouse ceiling. The deformation degree measurement sensor module 150 can measure the height change of the ceiling using a laser or an acoustic wave.

For example, the deformation degree measurement sensor module 150 may include a sensor having a light source and a light receiving unit. The light emitted from the light source receives the light reflected from the greenhouse ceiling at the light receiving unit and transmits the received value to the control unit 200. Here, the light source may be an LED or a short-wavelength laser light source. A photoelectric conversion element can be used as the light receiving portion. At this time, the strain measuring sensor module 150 may detect the wavelength or intensity of the reflected light to measure the deformation of the greenhouse ceiling and transmit the detected wavelength or intensity to the controller 200.

Here, the deformation degree measurement sensor module 150 periodically measures the degree of deformation of the ceiling at predetermined time intervals and transmits the measured deformation degree to the micro control unit 140 or receives the remote signal transmitted from the portable terminal 300 . In particular, the strain measuring sensor module 150 may be provided with at least two light sources and a light receiving unit so as to measure both deformation degrees of both sides of the greenhouse ceiling.

5, the deformation degree measurement sensor module 150 irradiates the light source to the lower surface of the greenhouse ceiling and receives the reflected light reflected from the greenhouse ceiling. At this time, when the snow does not fall on the outside of the greenhouse ceiling, the intensity of the reflected light has a small value. On the contrary, when the snow falls on the ceiling of the greenhouse, the intensity of the reflected light is greater than the intensity of the reflected light when the snow is not lowered. The measured intensity of the reflected light is transmitted to the control unit 200.

Further, the wavelength of the reflected light reflected from the greenhouse ceiling is measured and transmitted to the control unit 200. 6, when the greenhouse ceiling is partially deformed, the wavelength of the reflected light is measured and transmitted to the control unit 200. [

The micro control unit 140 refers to a dedicated processor for controlling a specific system and functions as a brain of the sensing unit 100. More specifically, it functions to process or modify various information inputted through the growth environment measurement sensor module 110. Further, the micro control unit 140 generates image data by combining the photographing position of the camera module 120 and the photographed image. At this time, the photographing position of the camera module 120 may be an identification sensor installed on a rail inside a greenhouse or Wifi, bluetooth or the like, which will be described below.

The sensing unit 100 includes a wireless communication module 130 for wirelessly transmitting growth environment information or image data to the control unit 200. The wireless communication module 130 may include a Wifi communication module, But is not necessarily limited thereto.

The moving body 430 can be installed to move along the rail 440 installed in the greenhouse.

The rail 440 may be an I-shaped long frame or the like and is used as a moving path of the moving body 430. At least one rail 440 may be provided in the longitudinal direction of the greenhouse, or a plurality of rails may be separated.

The moving body 430 may include a sensor receiving portion 432, a power receiving portion 434, a conveying wheel 436, and a mounting wheel 438.

The sensor accommodating unit 432 may mount the sensing unit 100 such as the sensor module 110, the camera module 120, and the micro control unit 140. At this time, the sensor receiving portion 432 may be formed in a hemispherical shape.

The power receiving portion 434 may receive power means such as a motor to transmit power to the conveying wheels 436 or the mounting wheels 438. [ The power receiving portion 434 may be provided with a conveying wheel 436 and a mounting wheel 438 on its upper surface.

The conveying wheels 436 are installed so that two wheels rotate in the horizontal direction with the upper surface of the power receiving portion 434 and can be rotated in close contact with both sides of the vertical portion of the 'I' shaped rail 440. The moving wheel 436 can move the moving body 430 along the rail 440 by a motor or the like installed in the power receiving portion 434 by receiving power from the power means.

Two mounting wheels 438 are provided at the front end and two at the rear end, and are installed closely to the upper surface of the lower end portion of the 'I' shaped rail 440. Accordingly, the conveying wheel 436 is prevented from being detached from the rail 440 when the moving body 430 is moved, and can be easily moved along the rail 440.

The movement of the moving object 430 is controlled by the server 200. In more detail, the server 200 can control the motor by wired or wireless lines or the power means inside the moving body 430.

Meanwhile, at least one identification sensor 460 may be installed on the rail 440. The identification sensor 460 can recognize that the moving body 430 has passed the position where the identification sensor 460 is installed when the mounting wheel 438 of the moving body 430 is stepped on and the approximate position of the moving body 430 This is possible.

7 and 8, the control unit 200 may include a communication interface unit 210, an environment control unit 200, an image data processing unit 230, a storage unit 240, and an alarm unit 250 .

Specifically, the communication interface 210 receives growth environment information and image data information transmitted from the sensing unit 100 in real time. Wired communication is possible, but wireless communication is more preferable. A detailed description of the wireless communication will be omitted.

The environment control unit 200 generates a control signal for controlling the temperature, the humidity, the intensity of the incident light, or the concentration of the carbon dioxide using the growth environment information sensed by the sensor module 110, and transmits the control signal to each device . 1, the environment control unit 220 generates a signal for controlling the switch a, the irrigation pump b, the fluid pipe c, and the like, which are connected to the control unit 200.

For example, if the temperature does not match the preset temperature, the peripheral device is controlled by opening / closing the window through the switch (a) or by generating a signal to activate the cold / warm fan. In addition, even when the humidity is not matched, a signal for operating the irrigation pump (b) is generated and activated, or an automatic control such as generating a signal for activating the light shielding film when the incident light intensity is out of the set range is made possible.

The image data processing unit 230 determines a plant in which a growth abnormality has occurred. When the plant grows abnormally, the color of the leaf surface is discolored or discolored. In addition, visually identifiable anomalies such as sudden changes in shape of the leaves or shrinkage may occur. The image data processing unit 230 compares the already stored image data with the image data generated by the current photographing so as to determine whether the shape of the leaf has changed suddenly or not by various algorithms.

In order to allow a more detailed photographing of a changed state such as a state improvement, the image data processing unit 230 controls the camera module 120 in the sensing unit 100 to selectively zoom in and zoom out images Take a picture. At the same time, the motion of the moving body 430 on which the camera module 120 is mounted can be controlled by the image data processing unit 230.

The storage unit 240 stores information on the temperature, humidity, light intensity or carbon dioxide concentration input by the user, and stores image data.

When the plant is cultivated, the optimal temperature, humidity, light intensity or carbon dioxide concentration for cultivation is input and stored in the storage unit 240, and the real-time growth environment information input from the sensing unit 100 is transmitted to the control unit 200 The controller 200 determines whether the growth environment information is within the optimal temperature, humidity, light intensity, or carbon dioxide concentration range stored in the storage unit 240. [

The image data stored in the storage unit 240 is stored in the image data processing unit 230 for use as reference data for searching for plants exhibiting abnormal growth patterns.

In addition, the storage unit 240 may store the deformation information of the ceiling collected by the deformation measuring sensor module 150.

The alarm unit 250 can calculate the degree of deformation of the greenhouse ceiling using the signals input from the deformation degree measurement sensor module 150. [ At this time, the alarm unit 250 determines that snow is accumulated when the intensity of the reflected light is larger than the reference value. Then, the distance between the moving body 430 and the greenhouse ceiling can be calculated using the optical wavelength inputted from the deformation degree measuring sensor module 150. At this time, the alarm unit 250 compares the reference distance value between the moving body 430 and the greenhouse ceiling to measure the degree of deformation. At this time, the reference distance value is stored in the storage unit 240, and the reference distance value may be a distance value using a light wavelength received on a clear day or a distance value using a previously received light wavelength.

The alarm unit 250 recognizes that the deformation has occurred when the measured distance value is smaller than the reference distance value and can transmit the alarm signal to the portable terminal 300. [

The alarm unit 250 generates an alarm signal as described above even when the light shielding film is installed on the greenhouse ceiling. In this case, the alarm unit 250 detects the light shielding film operation Signals can be transmitted simultaneously.

In addition, the greenhouse monitoring system according to the embodiment of the present invention can remotely move the sensing unit, capture a desired plant in real time, and provide information on the desired plant.

In addition, the greenhouse monitoring system according to the embodiment of the present invention can measure the degree of deformation of the greenhouse ceiling and prevent the risk of collapse of the greenhouse by providing an alarm to the portable terminal in advance when snow is accumulated outside the greenhouse ceiling.
