1 is a block diagram illustrating the operation of the automatic temperature control system of the greenhouse and barn according to the present invention, Figure 2 is a flow chart for explaining the operation of the automatic temperature control system of the greenhouse and barn according to the present invention. .

As shown in Figure 1, the automatic temperature control system of the greenhouse and barn in accordance with the present invention is installed a temperature sensor 100 for detecting the temperature in the greenhouse and the barn and a water sensor 110 for detecting the rainfall state do. At least one or more temperature sensor 100 and the water sensor 110 is installed in the greenhouse and barn. The output stages of the temperature sensor 100 and the water sensor 110 are installed in the greenhouse and the barn in order to adjust the temperature of the greenhouse and the barn to the optimum temperature input by the user according to the temperature change state and the rainfall state in the greenhouse and the barn. It is connected to the control device 130 for controlling the opening and closing operation of the opening and closing membrane. One end of the control device 130 is connected to the key input unit 120 for receiving a key operation of the user.

In addition, a display device 140 for displaying the current temperature state of the greenhouse and livestock house, the temperature set by the user, and the operation state of the device is connected to the output terminal of the control device 130, and controls the control device 130. The driving device 150 for opening and closing the opening and closing membrane installed in the greenhouse and the barn is connected. Drive device 150 is composed of a plurality of relay switches for opening and closing the power applied to the drive motor (not shown) for transmitting the driving force to the winding rod for winding or unwinding the opening and closing membrane installed on the upper and / or side of the greenhouse and the barn do.

In addition, the automatic temperature control system of the greenhouse and barn according to the present invention, if necessary, the ventilation device 160 and the greenhouse and barn internal temperature for forcibly ventilating the inside of the greenhouse and the barn become the upper and lower limits. An alarm device 170 for alarming may be mounted at an output end of the control device 130.

The detailed operation of the automatic temperature control system of the greenhouse and the barn according to the present invention configured as described above will be described with reference to FIG. 2.

When power is applied to the automatic temperature control system of the greenhouse and the barn, the display device 140 for visually displaying the temperature and the set function is operated. (Step S1) The user views the display device 140 and the key input unit 120. (Step S2-S3) That is, the user sets the temperature range, the proportional control function, the set temperature, the operating time, the stop time, and the like through the key input unit 120.

When the user sets various functions through the key input unit 120, the control device 130 detects the current temperature in the greenhouse and the barn by the detection of the temperature sensor 100 (step S4). ) Detects an abnormality in the short circuit or disconnection of the temperature sensor 100 and the water sensor 110 and outputs a control signal to the display device 140 to visually display the sensor abnormality. After step S5-S6), the control device 130 to the alarm device 170 if the current temperature in the greenhouse and barn detected by the temperature sensor 100 is the upper limit temperature input by the user through the key input unit 120. It outputs a control signal and alarms it (steps S7-S8) and outputs a control signal to the alarm device 170 even when the current temperature in the greenhouse and barn is the lower limit temperature input by the user through the key input unit 120. Alarm (steps S9-S10).

However, if the present temperature of the greenhouse and the barn is not the upper limit temperature or the lower limit temperature, the control device 130 determines whether the present temperature in the greenhouse and the barn is lower than the set temperature. (Step S11) The control device 130 If the current temperature in the greenhouse and barn is lower than the set temperature, after a predetermined time of about 5 seconds to 10 seconds has elapsed, it is determined whether the user sets the proportional control function through the key input unit 120, and then the user controls the proportional control. If the function is not set, a control signal is output to the driving device 150 to apply power to a driving motor that transmits driving power to a winding rod for winding or unwinding the opening and closing membrane installed on the upper and / or side surfaces of the greenhouse and the house. Block the opening and closing membrane mounted on the top and or side of the (steps S12-S13), where the user has set the proportional control function through the key input unit 120, the control device 130 Outputs a control signal to the driving device 150 only for a set time to supply power to the drive motor operating to block the opening and closing membrane to cut off the opening and closing membrane mounted on the upper and / or side of the greenhouse and barn so as to be proportional to the set time. The blocking operation of the opening / closing membrane is stopped. (Steps S15-S17) Here, the time set in step S15 coincides with the time when the blocking limit value of the closing machine is reached. That is, even when the closing limit value of the switch is reached, the control device 130 outputs a control signal to block the opening and closing membrane, so that power is applied to the magnetic or electric component without a need, thereby shortening the life of the device. Therefore, when a time of about 100 minutes, which is determined as the cutoff limit of the opening and closing membrane, passes in step S15, the control device 130 operates in a so-called slim mode to stop the blocking operation of the opening and closing membrane, thereby extending the sleep of the device and saving power. There is an effect of improvement. By this operation, the opening and closing membrane is blocked, so that the temperature in the greenhouse and the barn is raised.

In addition, if the present temperature of the greenhouse and the house is equal to the set temperature, after a predetermined time of about 2 seconds to 5 seconds has elapsed, a control signal is output to the driving device 150 to the upper and / or side surfaces of the greenhouse and the house. Maintains the current opening and closing state by cutting off the power of the driving motor which transmits the driving force to the winding rod for winding or unwinding the installed opening and closing membrane. (Steps S18-S20)

If the present temperature in the greenhouse and house is higher than the set temperature, the controller 130 sets a proportional control function through the key input unit 120 after a predetermined time of about 5 seconds to 10 seconds has elapsed. If the user does not set the proportional control function, and then outputs a control signal to the driving device 150 to the driving motor for transmitting the driving force to the winding rod for winding or unwinding the opening and closing membrane installed on the upper and / or side of the greenhouse and livestock house. The power is applied to open the opening and closing membrane mounted on the upper and / or side of the greenhouse and the house. (Steps S21-S24) Here, if the user sets the proportional control function through the key input unit 120, the control device 130 is set. Greenhouse and shaft so as to be proportional to the set time by applying power to the drive motor that operates to open and close the membrane by outputting a control signal to the drive device 150 only for a period of time A is opened to stop the opening attached to the top and or side to stop the opening operation of the two closing. Time is set (step S25-S27) Here, the step S26 is matched to the time it reaches the opening limit of the total waste. That is, even when the opening limit value of the switch is reached, the control device 130 outputs a control signal for opening the opening / closing membrane, so that power is applied to the magnetic or electric component without a need, thereby shortening the life of the device. Therefore, when about 100 minutes of time determined as the opening limit of the opening and closing membrane in step S26, the control device 130 is operated in a so-called slim mode to stop the opening operation of the opening and closing membrane to extend the sleep of the device, as well as the power saving effect There is an effect of improvement.

Therefore, the outside air flows into the greenhouse and the livestock house, thereby lowering the temperature inside the greenhouse and the livestock house.

In addition, if the temperature of the greenhouse and the barn rises separately, the control device 130 may output the control signal to the ventilation device 160 as needed to operate the ventilation device 160 for a set time.

Finally, the control device 130 detects the rainfall state by the output of the water sensor 110, and if it is determined that the current rainfall state, the control device 130 has a predetermined time of about 5 seconds to 10 seconds Then, power is applied to the driving motor that blocks the opening and closing membrane by outputting a control signal to the driving device 150 to block the opening and closing membrane mounted on the upper and / or side surfaces of the greenhouse and the house. (Steps S28-S30)

In the automatic temperature control system of the greenhouse and barn according to the present invention, a predetermined waiting time when the control device 130 outputs a control signal to the driving device 150 in preparation for the case in which the driving motor, such as the forward and reverse rotation, is damaged. Control to have

As described above, the present invention is suitable for a set temperature range by detecting a temperature state and rainfall in a greenhouse and / or barn, and can cope appropriately with a rain state, and automatically shuts off or closes the opening and closing membrane so that the driving device does not become excessive. Opening has the effect of increasing convenience for the management of greenhouses and houses.
