The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail with reference to the drawings. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Like reference numerals are used for like elements in describing each drawing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is simple in structure, easy to manufacture, low in manufacturing cost, can control the driving of the motor according to speed and weight, and also can reduce standby power and unnecessary power consumption.

As shown in FIG. 2, the integrated controller using the inverter control according to the present invention is supported by a guide frame 300 so as to be able to be elevated and lowered. The integrated controller is wound around the winding bar 200, And a motor for rotating the winding bar to control the driving of the motor 100. The inverter controller controls the operation of the motor.

As shown in FIG. 1, the controller of the present invention includes an encoder 10 installed at one side of the motor and sensing the rotation speed and load of the motor shaft. A controller (20) for calculating an ascending / descending speed of the shutter from the rotational speed of the motor shaft sensed by the encoder, and controlling the speed of the power supplied to the motor through an inverter method; And a touch screen 30 for inputting a control signal to the controller and displaying the open / closed state of the door.

The encoder 10 may use a conventional rotary encoder as a means for sensing the rotation speed of the motor and the position of the rotation axis. The controller 20 calculates the rotation speed of the motor by the rotation speed sensed by the encoder , The speed at which the shutter is opened or closed can be sensed by calculating the winding length of the shutter wound on the winding bar 200 from the rotational speed of the motor.

In addition, the controller 20 may calculate the rotation speed of the motor depending on the weight of the shutter wound on the winding bar, calculate the load applied to the motor from the rotation speed of the motor according to the weight of the shutter, To control the power supplied to the motor.

The controller calculates the speed at which the shutter is lifted and lowered from the rotational speed of the motor sensed by the encoder 10 and the load applied to the motor to control the power supplied to the motor. In other words, it is controlled by the inverter method through the frequency control of the power supplied to the motor.

The controller 20 controls the open / close speed of the shutter according to a set value input by the user, and the touch screen 30 is provided as means for inputting a value desired by the user.

As described above, the touch screen 30 can display not only a control command but also a current shutter opening / closing speed, a load applied to the motor, a rotation speed, and the like, and displays the history of the shutter opening / You may.

Of course, the information such as the history of opening and closing of the shutter, the failure history, and the like displayed on the touch screen 30 is stored in the memory provided in the controller 20. [

The controller 20 can open or close the shutter by driving the motor for a predetermined time, and the opening / closing time can be calculated from the rotation speed of the winding bar rotated by the motor and the length of the shutter.

In addition, the controller of the present invention further includes an infrared sensor (40) for sensing a vehicle or a person approaching a doorway on one side of the guide frame.

The infrared sensor 40 functions to prevent a person or a vehicle from being damaged due to the motor being driven unintentionally by shutting off the power supplied to the motor when a person or a vehicle is present at the doorway.

Of course, a plurality of the infrared sensors 40 may be installed. Some of them are installed toward the front or rear of the entrance, and some are installed between the entrance and exit to detect an object moving toward the entrance, When an opening signal is transmitted to the controller or when the shutter is lowered in a state where an object is present at an entrance, the shutter is detected and the stop signal is transmitted to the controller so that the shutter does not descend any further.

Further, an emergency switch 50 is further provided.

The emergency switch 50 serves to shut off the power supplied to the motor so that the shutter can not be lowered when the shutter is lowered because the motor is driven unintentionally due to malfunction of the infrared sensor or other electronic equipment.

That is, when an error occurs in the controller or the infrared sensor at the moment when the motor is driven and the shutter is lowered in the state where there is an object at the doorway, the motor is continuously supplied with power and the shutter is lowered. The object placed in the doorway may be damaged. In such a situation, the power supplied to the motor is cut off due to the depression of the emergency switch, so that the shutter can be prevented from falling as the mower stops.

Of course, even when the shutter is lifted up by the shutter in the process of raising the shutter, if the emergency switch is depressed, the power supplied to the motor is cut off and the shutter can be prevented from rising as the mower stops.

Further, the controller of the present invention may further include a standby power cut-off switch 70 to shut off power supplied to the motor when the motor is not operated between the motor and the commercial power supply so that standby power is not consumed.

The standby power cut-off switch 70 is operated by sensing a current supplied to the motor when the motor is driven, or by using rotational speed information sensed by the encoder, and when the motor is not operating, When the shutter is opened by detecting an object moving toward the entrance from an infrared sensor installed toward the front or rear of the doorway, the electric power is supplied to the motor by connecting a commercial power source.
