The basic principle of the present invention is to automatically measure the temperature and humidity inside the greenhouse to prevent dew from forming on the leaves of the plant, and then to remove the humidity or to prevent dew if the threshold value, which is a predetermined dew point temperature, is exceeded. It is about a method.

1 is a block diagram schematically showing a system for automatically controlling a greenhouse environment according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the automatic greenhouse environment control system 100 according to the present invention calculates a dew point temperature according to a sensing device 110 for measuring an environment inside a greenhouse and a wirelessly received measurement value from the sensing device 110. A base unit 120, a control unit 130 for storing the dew point temperature calculated by the base unit 120 and the wirelessly received measured value and transmitting a control command according to preset information, and when the control command is received, The relay device 140 short-circuits a relay and inputs the control command to at least one corresponding device, and when the relay is connected, the devices are activated so that dew does not form in the greenhouse according to the control command. It is configured to include an environmental control device 150 for adjusting the environment.

Operation of the automatic greenhouse environment control system 100 according to the present invention configured as shown in Figure 1 is as follows.

First, the sensing device 110 measures temperature and humidity inside the greenhouse and rainfall outside the greenhouse.

Preferably, the temperature of the plant leaves is measured using a contact sensor.

In addition, the sensing device 110 further includes a rain sensor.

The rain sensor detects whether rain outside the greenhouse.

The measured values collected and collected as described above are periodically transmitted to the base apparatus 120.

Preferably, the sensing device 110 wirelessly transmits the measured value to the base device.

The base unit 120 calculates the dew point temperature based on the received measurement.

Thereafter, the base apparatus 120 transmits the received measured value and the calculated dew point temperature to the controller 130.

Here, the base device 120 communicates with the control device 130 using a wired or public network.

In the case of the communication, a method such as the Internet, serial port communication, or Universal Serial Bus (USB) communication may be used.

Then, the control device 130 stores the measured value received from the base device 120 and the calculated dew point temperature.

Here, when it is determined that the received measured value is the dew point temperature which is the generation temperature of the dew, the control device 130 transmits a control command to the relay device 140 according to preset information.

In addition, the control device 130 further includes a display unit for displaying a controller so that the controller can check the received measured value and the calculated dew point temperature.

That is, the controller may monitor the current greenhouse environment through the display unit.

If a problem occurs in the greenhouse environment because a preset threshold is exceeded, the display unit may alert the controller of the current situation using a means such as blinking.

The controller may then enter appropriate control commands to control the indoor environment of the greenhouse.

On the other hand, when the dew is generated temperature, it is possible to automatically transmit a control command necessary to adjust the indoor environment of the greenhouse according to a predetermined command.

In addition, the control command also includes a command as to whether to open the window if the rain outside the greenhouse.

In other words, do not open the window if it rains outside.

Here, the control command generated by the control device 130 is transmitted via the base device 120.

As such, when the control command is transmitted to the relay device 140 via the base device 120, the relay device 140 transmits the control command to the environment control device 150.

Preferably, the relay device 140 acts as a kind of switch that connects the control device 130 and the environmental control device 150 by operating an internal relay when receiving the control command.

Accordingly, the environmental control device 150 receiving the control command operates the internal warm fan or the fan so that dew is not generated in the greenhouse according to the control command.

In addition, if the information sensed by the rain sensor is information that the rain outside the greenhouse does not open the window of the greenhouse.

Here, each of the devices 110, 120, 130, 140, and 150 of FIG. 1 will be described in detail with reference to FIGS. 2 to 6.

2 is a detailed block diagram showing in detail the sensing device 110 of FIG. 1 according to an embodiment of the present invention.

2 shows the same reference numerals for the same members of FIG. 1.

2, the sensing device 110 according to the embodiment of the present invention is a leaf temperature sensor 111 for measuring the temperature of the leaf, leaf wetting sensor 112 for measuring the humidity of the leaf, and the atmosphere of the greenhouse Atmospheric temperature sensor 113 for measuring the temperature, Atmospheric humidity sensor 114 for measuring the humidity of the atmosphere in the greenhouse, Rain sensor 115 for detecting the presence of rain outside the greenhouse, and the sensors (111 ~ 115) A collection unit 116 collecting the values measured in step 2), a transmission unit 117 transmitting the measurement values collected by the collection unit 116, and a first transmission unit for transmitting transmission information of the transmission unit 117. It is configured to include an antenna 118.

The operation of the sensing device 110 according to the embodiment of the present invention configured as shown in FIG. 2 is as follows.

First, the leaf temperature sensor 111 measures the temperature of the leaf.

Here, the leaf temperature sensor 111 is preferably configured as a contact sensor in order to accurately measure the temperature of the leaf.

On the other hand, the leaf wetting sensor 112 measures the humidity of the leaf.

The reason for measuring the humidity of the leaf with the leaf wetting sensor 112 is to prepare for the dew condensation by the environment in the greenhouse even when the temperature inside the greenhouse is not the dew point temperature.

Meanwhile, the sensing device 110 further includes an air temperature sensor 113 and an air humidity sensor 114 to measure the state of the atmosphere in the greenhouse.

This is because plants are inhibited from photosynthesis at a relative humidity of 40% or less, and excessively increase the amount of lateral growth at 20% or less.

In addition, at 80% or more, the photosynthetic action is disturbed, so that the growth of germs is easy, and the disease resistance of plants is also reduced.

Therefore, the air temperature sensor 113 and the air humidity sensor 114 is further provided to measure the temperature and humidity of the atmosphere in the greenhouse.

Preferably, the atmospheric temperature sensor 113 and the atmospheric humidity sensor 114 may be configured as one module.

Finally, the sensing device 110 further includes a rain sensor 115.

The rain sensor 115 detects whether the rain outside the greenhouse.

This is to prevent the windows provided in the greenhouse from opening in the rain when the dew is generated inside the greenhouse.

This is because if the rain opens a window today, the relative humidity rises and eventually the dew point temperature rises.

As such, the temperature and humidity values of the leaves and the atmosphere of the plants in the greenhouse measured by the sensors 111 to 115 are transmitted to the collecting unit 116.

Then, the transmitter 117 wirelessly transmits the measured leaves and the atmosphere temperature and humidity values of the plants in the greenhouse and the measured antenna 118 that detects the rain outside the greenhouse.

That is, the sensing device 110 is provided with the respective sensors 111 to 115 and collects the leaf and air temperature and humidity values of plants in the greenhouse and rainfall information outside the greenhouse, and is shown in FIG. 1. Wireless transmission to one base apparatus 120 is performed.

Preferably, each of the sensors 111 to 115 collects sensing data at 5 second intervals.

However, if the dew point temperature is higher than the leaf temperature, it can be used as a timer by increasing the counter from which sensing data will be collected.

For example, it is 5 seconds per count, and the counter 360 is 30 minutes.

Therefore, if the dew point temperature is higher than the leaf temperature, dew forms on the leaves.

For this reason, the count is used to operate the devices by means such as a timer.

3 is a detailed block diagram illustrating in detail the base apparatus 120 of FIG. 1 according to an exemplary embodiment of the inventive concept.

3 shows the same reference numerals for the same members of FIG. 1.

A first transceiver 122 which attenuates noise of the received measurement value and amplifies and transmits a signal; an arithmetic unit 123 that calculates a dew point temperature based on the measurement value received by the first transceiver 122; The first transceiver unit 122 that receives the measured value and the dew point temperature calculated by the calculator 123, and the first transceiver 122 configured to transmit the measured value and the dew point temperature calculated by the first transceiver 122 to the outside. 1 communication port 124 is included.

The operation of the base apparatus 120 according to the embodiment of the present invention, configured as shown in FIG. 3, is as follows.

First, a measurement value wirelessly transmitted through the first antenna 118 of FIG. 2 is received by the second antenna 121.

Then, the measured value is transmitted to the calculator 123 via the first transceiver 122.

Preferably, the first transceiver 122 serves to attenuate the noise of the signal being transmitted and received and to amplify the signal strength.

Thereafter, the calculator 123 calculates the dew point temperature based on the measured value.

Here, a method of calculating the dew point temperature in the calculator 123 will be described.

Firstly, the measured values consist of the ambient temperature and humidity inside the greenhouse, the temperature of the leaves of the plant and the humidity of the leaves.

의 오차 값을 갖는 Barenbrug 이슬점 계산식에 대입시킨다.The data transmitted as described in <Equation 1>

Substitute the Barenbrug dew point equation with the error value of.

Effective range Remark

Equation 1 is as follows.

here,

That is, it is determined that the dew forms an environment when the dew point temperature calculated as in Equation 1 is higher than the leaf temperature.

In this way, the dew point temperature calculated by the calculation unit 123 based on the measured value is transmitted to the first transceiver 122 again to be transmitted to the outside.

Then, when the first transceiver 122 transmits the dew point temperature and the measured value to the first communication port 124, the calculated dew point temperature and the measured value are externally transmitted via the first communication port 124. Is sent.

Preferably, the first communication port 124 may be a wired port such as a serial port or a universal serial bus (USB).

4 is a detailed block diagram showing in detail the control device 130 of FIG. 1 according to an embodiment of the present invention.

It is configured to include.

Operation of the control device 130 of FIG. 1 according to the embodiment of the present invention configured as shown in FIG. 4 is as follows.

First, the second communication port 131 is the first communication port of FIG. 3 as the second communication port 131 that receives the calculated dew point temperature and the measured value transmitted from the first communication port 124 of FIG. 3. The same serial port or wired port such as Universal Serial Bus (USB) may be used to be compatible with 124.

Upon receiving the calculated dew point temperature and the measured value at the second communication port 131, the first controller 132 compares the calculated dew point temperature value with the current leaf temperature.

If the dew point temperature exceeds the threshold of dew condensation, a control command is generated to prevent dew condensation or to remove dew.

As an example of the control command, when the temperature measured by the leaf temperature sensor of FIG. 2 exceeds the temperature of the calculated dew point, the window is automatically opened to control the environmental controller 150 of FIG. Generate control commands to run devices such as circulation fans.

Preferably, the measurement does not generate a command to open the window if it is raining outside the greenhouse.

Here, the control command of the environmental control device 150 of FIG. 1 varies depending on the degree of excess of the threshold value for generating dew.

In other words, the higher the threshold value, the more the devices included in the environmental control device 150 are operated, or a control command is generated to operate at a higher level.

On the other hand, even if the calculated dew point temperature does not exceed the threshold value, if the humidity of the leaf of the measured value is high can generate a control command for removing the humidity.

In this case, the controller may manually input a control command through the input unit 134.

Such a series of processes are displayed on the display 135 to be recognized by the controller.

In addition, the storage unit 133 stores the measured value, the calculated dew point temperature, the generated control command, operation step and time information of the actual devices, and the like.

The storage unit 133 may be a high capacity memory medium such as a hard disk drive.

Because it is necessary to store information continuously, it is appropriate to use a high capacity storage medium.

Meanwhile, the control command generated as described above is transmitted to the first communication port 123 of FIG. 3 again through the second communication port 131.

Then, the control command is wirelessly transmitted to the relay device 140 of FIG. 1 via the first antenna 121 through the first transceiver 122 of FIG. 3.

5 is a detailed block diagram illustrating in detail the relay device 140 of FIG. 1 according to an exemplary embodiment of the present disclosure.

5 shows the same reference numerals for the same members of FIG. 1.

Referring to FIG. 5, the relay device 140 according to an embodiment of the present invention receives a control command received from the first antenna 121 of FIG. 3 via the third antenna 141 to remove noise and to receive a signal. And a second control unit 142 for amplifying a and a second control unit 143 for operating the relay 144 when the control command is input.

The operation of the relay device 140 according to the embodiment of the present invention configured as shown in FIG. 5 is as follows.

First, referring to FIG. 4, the control command generated by the first control unit 132 is transmitted to the first communication port 124 of FIG. 3 through the second communication port 131.

Thereafter, the control command is transmitted from the first communication port 124 to the second transceiver 142 through the third antenna 141 of FIG. 5 via the first antenna 121 through the first transceiver 122. Is received).

Then, the second transceiver 142 attenuates the noise of the control command, amplifies the signal strength, and transmits the signal to the second controller 143.

As such, when the control command is input to the second control unit 143, the second control unit 143 operates the relay 144.

Preferably, the relay 144 is a kind of switch, and the relay 144 connected to the device to which the control command is input is shorted with the specific device of the environmental control device 150 of FIG. 1.

That is, the relay 144 may be shorted only when the control command is input to the relay device 140, and thus the control command may be transmitted to the environmental control device 150.

In addition, since the environmental control device 150 includes at least one or more devices, the relay 144 is provided with the number of devices provided in the environmental control device 150.

6 is a detailed block diagram showing in detail the environmental control device 150 of FIG. 1 according to an embodiment of the present invention.

6 shows the same reference numerals for the same members of FIG. 1.

Operation of the environmental control device 150 according to an embodiment of the present invention, configured as shown in Figure 6 is as follows.

For example, if the control command is a command for controlling the hot air heater 151 and the boiler 152, the relay 144 connected to the hot air heater 151 and the boiler 152 is shorted and operated after the corresponding control command is input. .

That is, the relay connected to the specific device to which the control command is to be operated is shorted.

Therefore, the relay 144 is preferably provided according to the number of each device.

In addition, each relay 144 is preferably attached to each timer is activated for a predetermined time.

Here, the controller may arbitrarily set a predetermined time.

However, if the measured value received from the sensing device 110 shows that the state in the greenhouse is normal, the control device 130 may clear the remaining time of the timer.

That is, when the temperature of the leaf is lower than the dew point temperature, the control command will be a command to increase the temperature of the leaf by driving the warm fan 151 or the boiler 152.

On the other hand, even when the leaf temperature is higher than the dew point temperature, if the humidity values measured by the leaf wetting sensor 112 and the atmospheric humidity sensor 114 of FIG. 2 are high, the control command operates the window controller 154 to open the window. Open it, ventilate or operate the other device to remove the humidity.

Here, if the value detected by the rain sensor 115 of FIG. 2 includes information indicating that rain is outside the greenhouse, the control command includes a command not to open a window.
