Description

SMART OPENING AND SHUTTING DEVICE AND SYSTEM HAVING THE SAME}

The present invention relates to a smart switchgear and a smart switchgear including the same, and more particularly to a smart switchgear and a smart switchgear system including the same used in gardening facilities, such as smart greenhouse.

The cultivated plants are greatly influenced by their external environmental factors such as ambient temperature and humidity. Therefore, in the past, crops that can be cultivated have been limited according to external environmental factors of the growing region, but since the development of greenhouses and the like, the limited crops have been reduced as humans can control these external environmental factors. .

On the other hand, the greenhouse for growing crops is required to open and close the greenhouse in order to control the temperature, humidity, ventilation and the like in the greenhouse. For such opening and closing, a system for opening and closing a greenhouse by winding or unwinding a screen for shading or thermal insulation to a winding pipe is widely used.

Such a winding pipe is driven by a switch including a motor. In the related art, when the opening degree (1 to 100%) application technology is used in an indirect manner with time, a problem occurs frequently.

The mode switch 120 switches the smart switch 200 to an automatic mode or a manual mode. When the mode switch 120 sets the smart switch 200 to the automatic mode, the smart switch 200 is automatically driven according to the environment inside the greenhouse such as temperature and humidity.

The manual mode switch 130 manually drives the smart switch 200 in the manual mode of the mode switch 120. That is, the user controls the driving of the smart switch 200 by operating the mode switch 120.

The power line communication module 150 enables transmission and reception of the control signal of the control unit 140 to the smart switch 200 by power line communication.

The smart switch 200 receives power from the power supply 110 through the power line 300, and receives a control signal from the control unit 140 through power line communication through the power line 300 to screen Rotate the winding pipe connection to wind the coil.

Therefore, the smart opening and closing system according to the present invention utilizes the power supply line 300 for supplying power as a control line for controlling the operation of the smart switch 200, thereby eliminating the need for a separate control line.

The winding pipe connection part 250 is connected to a winding pipe (not shown) winding the screen of the greenhouse (not shown), and rotates the winding pipe (not shown) to wind or unwind the screen to raise or lower the screen. In order to prevent the sudden rotation of the winding pipe (not shown), the reduction unit 220 may reduce the rotation of the motor 210 and transmit the deceleration unit 220 to the winding pipe connection unit 250. Since the gear configuration of the reduction unit 220 is obvious to those skilled in the art, a detailed description thereof will be omitted.

The smart control unit 230 is connected to the deceleration unit 220 to control the rotation angle of the winding pipe connection unit 250. In more detail, in the memory (not shown) of the control unit 140, the rotation angle of the winding pipe connection unit 250 is stored so as to be in a state of being fully opened from the maximum closed state. An appropriate amount of open state of the screen is stored according to temperature and humidity, external temperature and humidity. Accordingly, when the mode switch 120 is in the automatic mode, according to the sensed temperature and humidity, the processor (not shown) of the controller 140 rotates the rotation angle of the winding pipe connection 250 necessary for the open state of the screen. When the calculated rotation angle is transmitted to the power line communication module (not shown) of the smart control unit 230 through the power line communication module 150, driving of the motor 210 is performed according to the transmitted rotation angle. Control

The opening and closing amount setting unit 240 is connected to the smart control unit 230 to limit the rotation angle of the winding pipe connection unit 250 within the opening and closing amount setting range input from the user.

It may further include a third spur gear 233 to make the same rotation direction.

The first spur gear 231 is connected to the reduction unit 220. Therefore, when the first spur gear 231 rotates in conjunction with the gear of the a reduction unit 220, the third spur gear 233 rotates, and accordingly, the third spur gear 233 The interlocked second spur gear 232 is rotated. In this case, the second spur gear 232 is interlocked with the first spur gear 231 to measure the rotation angle of the first spur gear 231.

As described above, in the smart switch 200 according to the present invention, the second spur gear 232 is interlocked with the first spur gear 231 to measure the rotation angle of the first spur gear 231, thereby providing a first switch.

Restrict.

For example, the first limit gear 242 may set the maximum opening value (or the maximum opening degree), and the second limit gear 243 may set the maximum closing value (or the minimum opening degree). Or vice versa.

That is, when opening, when the first limit gear 242 rotates, and reaches the maximum opening value, the rotation of the first limit gear 242 is stopped, and accordingly the fourth spur gear 241. And the driving of the first spur gear 231 is stopped, and the first spur gear 231 stops the rotation of the reduction unit 220.

On the contrary, when closing, when the second limit gear 243 rotates and reaches the maximum opening value, the rotation of the second limit gear 243 is stopped, and accordingly the fourth spur gear 241. And the driving of the first spur gear 231 is stopped, and the first spur gear 231 stops the rotation of the reduction unit 220.
