The planetary gear has a front end portion coupled to a gear formed on an inner peripheral surface of the rotating ring gear portion, and a rear end portion coupled to a gear formed on an inner peripheral surface of the fixed ring gear portion.

In particular, the planetary gear rotates and simultaneously rolls along the inner circumferential surface of the fixed ring gear to reduce the rotation of the rotary ring gear.

That is, in the electronic green house opening/closing apparatus according to the present invention, when the motor unit 100 generates an initial driving force, the torque increases while passing through the reduction unit 200 to open and close the side length of the green house.

The detailed structure and operation of the motor unit 100 and the reduction unit 200 as described above are as disclosed in the prior art document.

A plurality of electronic plastic house opening and closing devices according to the present invention are driven by receiving power from the main body 10, and the electronic limit device 300 of the electronic green house opening and closing device checks the polarity of the power source and, if necessary, changes the polarity. It is changed so as to be output to the motor unit 100.

The electronic limit device 300 is installed at the lower rear of the reduction unit 200 instead of the conventional mechanical limit device as shown in FIG. 2B.

More specifically, as shown in FIG. 3, the electronic limit device 300 includes an input unit 301, a polarity check unit 302, a relay 303, an output unit 304, a display unit 305, and a main control unit 306. ), a setting encoder 307, a memory unit 308, a time setting unit 309, and a communication unit 310.

The input unit 301 is connected to the main unit 10 to receive power applied from the main unit 10.

The polarity check unit 302 is connected to the input unit 301 to monitor the power input terminal and checks the polarity of the power supplied from the main unit 10 to the input unit 301.

The polarity check unit 302 transmits the polarity check result of the power input to the input unit 301 to the main control unit 306.

In the relay 303, a plurality of switches are connected therein to change the switching contact point of the switch under the control of the main control unit 306, so that the input unit 301 changes the polarity of the input power and outputs it.

That is, when the power terminal of the input unit 301 is composed of red and black, when the power input to the red power terminal is `+` and the power input to the black power terminal is `-`, the relay 303 is Under the control of the main control unit 306, likewise, the red terminal of the output unit 304 composed of red and black power terminals can output the power'+' and the black terminal can output power'-', and the switching contact can be changed. As a result, the red terminal of the output unit 304 may be used to output a'-' and the black terminal may be used to output a'+' power.

In addition, the relay 303 opens and closes a switch under the control of the main control unit 306 to supply or cut off the power transmitted to the output unit 304.

That is, when the opening/closing motor of the motor unit 100 is rotated by the number of rotations set by the rotation setting unit 305, the relay 303 opens the included power supply switch and is supplied to the output unit 304. Power is turned off, and power is continuously supplied by maintaining the power supply switch in a closed state when the opening/closing motor is not rotated by the set number of rotations.

The number of revolutions set by the rotation setting unit 305 may be the number of revolutions of the opening/closing motor as described above, but more precisely, the deceleration connected to the opening/closing rod that rolls up the vinyl of the greenhouse to open or unwind it to close. It is preferable that the number of rotations is on the negative axis of rotation.

The output unit 304 is formed at the output terminal of the relay 303 and is connected to the motor unit 100 to output and supply power according to the polarity input to the input unit 301, or to the input unit 301 After input, the relay 303 outputs and supplies the power whose polarity is changed.

The rotation setting unit 305 is configured to set the number of rotations of the drive shaft of the motor unit 100, more precisely, the number of rotations of the rotational shaft of the reduction unit 200, and may be set by rotation.

That is, the rotation setting unit 305 rotates in a clockwise direction according to a manager's operation to increase the number of rotations of the drive shaft, and reversely rotates in a counterclockwise direction to decrease the number of rotations of the drive shaft.

In particular, the rotation setting unit 305 is rotated, and after determining the number of rotations of the drive shaft through rotation, the number of rotations may be determined through a pressing operation, and after determining the number of rotations of the drive shaft with a `-` sign, The number of rotations in the opposite direction can be determined.

The display unit 307 is interlocked with the rotation setting unit 305 to display the number of rotations of the drive shaft that increases by rotating clockwise of the rotation setting unit 305, and rotates counterclockwise to decrease the driving shaft. It displays the number of revolutions.

In this case, the display unit 307 may display the number of revolutions as a number and display a clockwise direction as `+` and a counterclockwise direction as `-`.

In the above, it has been described that the number of rotations of the drive shaft increases and decreases when the rotation setting unit 305 rotates in a clockwise direction and a counterclockwise direction, but is not limited thereto and may be set by operating differently.

The main control unit 306 controls the relay 303 by receiving the rotation direction of the open/close motor of the motor unit 100 by rotation of the rotation setting unit 305 and power polarity information of the polarity check unit 302 By doing so, the polarity of the power output to the output unit 304 is maintained or changed as it is when it is input to the input unit 301.

The memory unit 308 is an opening/closing motor of the motor unit 100 set by the rotation setting unit 305 so that the main control unit 306 can control the rotation of the motor unit 100 with driving information. The driving information for is stored.

That is, the motor unit 100 may be driven in real time according to the driving information set by the rotation setting unit 305 to open and close the vinyl house, but is driven by driving information previously stored in the memory unit 308 to You can also open and close the house.

The time setting unit 309 is configured to set the open time and the closing time of the green house, together with the number of rotations of the opening/closing motor (rotation shaft of the reduction unit) of the motor unit 100 set by the rotation setting unit 305 It is linked to form driving information.

That is, in the rotation setting unit 305, the number of rotations of the opening and closing motor (more precisely, the number of rotations of the rotation shaft of the reduction unit) is clockwise (green house open), and the number of rotations is 10 times, counterclockwise (green house is closed). If the number of rotations is set to 10, and the opening time and the closing time are set to 20 minutes and 30 minutes in the time setting unit 309, respectively, the opening and closing motor of the motor unit 100 is clockwise according to the set driving information. Roll the vinyl by 10 turns to open the greenhouse, and if 20 minutes of opening time has elapsed, rotate 10 counterclockwise to release the rolled vinyl and close the greenhouse.

Thereafter, when the closing time of 30 minutes has elapsed, the opening/closing motor of the motor unit 100 rotates 10 clockwise according to the set driving information again to open the vinyl house by rolling the vinyl.

As described above, the driving information is set to the number of rotations in the clockwise (green house open) 10 times, counterclockwise (green house closed) rotations 10 times, and the opening time and closing time are set to 20 minutes and 30 minutes, respectively. In the case, the electronic vinyl house opening and closing device according to the present invention repeatedly opens and closes the vinyl house as described above.

The clockwise rotation speed and the counterclockwise rotation speed of the opening and closing motor are set differently in the morning time, afternoon time, or late-night time or season for each time zone, in spring, summer, autumn, and winter, and the time setting unit 309 ) Can be set in various ways.

The communication unit 310 is configured to enable communication with an external device. In particular, the communication unit 310 may communicate with a mobile terminal such as a mobile phone of a green house manager to receive driving information of the reduction unit 200 transmitted from the mobile terminal.

As described above, the main control unit 306, which has received the driving information received by the communication unit 310, controls the relay 303 according to the setting information included in the corresponding driving information to control the opening/closing motor of the motor unit 100. It can also be driven.

The electronic limit device 300 of the electronic plastic house opening/closing apparatus according to the present invention further includes a rotation sensing encoder 311 formed at the end and formed on the reduction unit 200 connected to the opening/closing rod for rolling up the vinyl.

The rotation detection encoder 311 counts the rotation speed of the rotation shaft of the deceleration part 200 and transmits the counted rotation speed to the main control part 306.

Specifically, the rotation detection encoder 311 is formed on one side of the reduction unit 200 as shown in FIG. 4 and counts the number of rotations of a rotation shaft connected to an opening/closing rod that rolls up or unrolls the vinyl.

More specifically, the rotation detection encoder 311 includes a hall disk 311a, an LED light source 311b, and an LED light detection sensor 311c, as shown in FIG. 5.

In the hole disk 311a, a hole H formed in the center is inserted into the rotation shaft of the reduction unit 200 to rotate with the rotation of the rotation shaft.

In addition, the hole disk 311a has a plurality of holes h formed at equal intervals at the edge portion.

The LED light source 311b is positioned on one side of the hole disk 311a to irradiate the LED light into the hole h formed in the edge portion.

The LED light detection sensor 311c is formed at a position corresponding to the LED light source 311 in a direction opposite to the hole disk 311a.

In the rotation detection encoder 311 having the structure as described above, as the hole disk 311a rotates while the LED light source 311b is being irradiated, the LED light passes through the hole h The reduction unit by counting the hole (h) using a mechanism that is sensed by the LED light detection sensor 311c and is blocked where the hole (h) is not formed and is not detected by the LED light detection sensor 311c. The rotation speed of the rotation axis of 200 is detected.

For example, when the LED light sensor 311c detects light irradiated from the LED light source 311b and counts the number of holes h as 40, the rotation detection encoder 311 If the number of rotations of the rotation shaft of 200 is detected as one, when the number of holes h is counted as 400, it is sensed that the rotational shaft of the reduction unit 200 has rotated 10 times.

The main control unit 306 compares the number of rotations of the rotation axis of the reduction unit counted by the rotation detection encoder 311 with the rotation number of the rotation axis set in the rotation setting unit 305, and the rotation detection encoder ( When 311) detects the number of rotations, power supplied from the relay 303 to the output unit 304 is cut off.

On the other hand, the main control unit 306 is continuously powered from the relay 303 to the output unit 304 when the number of rotations detected by the rotation detection encoder 311 is smaller than the number of rotations set by the rotation setting unit 305. Let the supply come true.

In the above, the technical idea of the present invention has been described with reference to the accompanying drawings, but this is illustrative of a preferred embodiment of the present invention and does not limit the present invention. In addition, it is obvious that any person of ordinary skill in the technical field to which the present invention pertains can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
