The present invention relates to an automatic door controller and a method of operating the same, and more particularly, to diagnose the amount of traffic by considering the number of people entering and exiting the vehicle, and to optimize the opening and closing operation of the door by considering the diagnosis value in the door opening and closing control. The present invention relates to an automatic door controller having a traffic diagnosis function and an SMPS and a method of operating the same.

Automatic doors are often installed at entrances of hotels, large buildings, electric cars, etc. Depending on the type of opening and closing, sliding sliding doors / double sliding automatic doors / automatic doors with sliding and swinging doors / swivel automatic doors / opening doors It can be classified as an automatic door.

Automatic doors usually have a switch installed on the floor in front of the door, and the switch is configured to be driven when the person stepped on it to drive the door engine, or the fuselage to the door frame 10 near the door (door) as shown in FIG. When the light entering the photoelectric tube is blocked by a person approaching the door by installing a photoelectric tube, which is a sensing sensing unit (S), the door may be automatically opened by operating the door engine.

The door may be opened and closed by calculating the speed and the like reflected by emitting infrared rays to determine whether there is a moving object, and automatically reacting according to the determined value to drive the door engine.

The above-mentioned emission of infrared rays and the reception of reflected infrared rays are usually performed by an infrared sensor, which is usually installed at the center of the upper side of the door and also uses an ultrasonic sensor as in an autofocus camera. .

The door engine of the automatic door is driven by a signal from the sensor and automatically opens and closes the door. The door engine is divided into pneumatic, hydraulic, and electric motors depending on the force.

Meanwhile, a hydraulic door engine is widely used to open or close a large or heavy door, and the automatic door employing the hydraulic door engine includes the door engine and a link mechanism embedded in the upper door frame of the door or the door itself.

In addition, the electric door engine is also built into the space formed on the upper side of the door frame, and has a structure in which the upper end of the doors are respectively fixed to the upper and lower sections of the drive belt driven by the motor capable of forward and reverse rotation.

By the way, the conventional automatic door as described above has a problem that the door is opened more than necessary, regardless of the degree of entry and exit, because the time to maintain the door in the open state is given a fixed set value.

For example, even when there is a large amount of access traffic, the door is closed only when a time corresponding to a fixed set time has elapsed, and the door is reopened according to the detection information about the presence of a person who has been read again while the door is already closed, i.e. The door is repeatedly closed and opened until it is completed.

This operation not only shortens the lifetime of the automatic door system, but also wastes driving power energy and leads to a problem of increasing the cost of maintenance and management.

On the contrary, not only the problem of the door being opened for an unnecessarily long time even though the entry and exit traffic volume is very small, that is, the loss of heat energy of the room, but also the loss of heat energy as above by causing the door to be completely opened throughout the entire section. In addition to aggravating the problem, the waste of power energy due to driving as much as the unnecessary opening of the door is also aggravated, and thus, a method of solving these problems was required.

2 is a schematic configuration diagram of a connection state of a power supply unit of a conventional automatic door.

As shown, the upper and lower sections of the doors (not shown) are respectively fixed to the upper and lower sections of the driving belt (not shown) of the belt pulley 16 driven by the motor 14 capable of forward and reverse rotation. The moving position of the door is detected by the position sensor and input to the controller 30 so that the controller 30 can consider such input information in the opening and closing driving control of the door.

That is, by controlling the drive of the motor 14 by the controller 30 that senses the need to open and close, the door is to be opened and closed automatically.

On the other hand, in order to supply 24V direct current to the motor 14 driving unit, and supply 5V direct current to the plurality of sensors (2) (4) or the processor (6) (C) step-down AC current of the power supply 220V The DC current of 24V required to drive the motor 14 must be converted to obtain an AC current stepped down to 24V through a transformer 55 electrically connected to the power switch SW.

As described above, the transformer 55 may be variably adjusted to obtain a DC of 5V required for the plurality of sensors 2, 4, and the processors 6, and C, and thus, through the transformer 55. The resulting 24V direct current and 5V direct current are supplied to each current consuming element under the condition controlled by the controller 30.

However, according to the configuration as described above, the motor that generates the driving force for opening and closing the door is driven by applying a DC current of 24V, so there is a problem that the power efficiency is very low and the driving force enough to open and close the door cannot be obtained. .

In addition, it is easy to cause a case in which the time that the transformer is turned on becomes longer than the time that is turned off. Accordingly, as the output voltage increases, the input current increases, causing power loss. It had the disadvantage of raising the cost.

The present invention satisfies the conventional requirements as described above, and solves the problems associated with the conventional automatic doors, and the present invention does not allow the doors to be opened more than necessary or the doors are opened and closed unnecessarily according to the traffic volume. In addition, it has a main purpose to provide an automatic door and its operation method to open the door as many times as necessary.

The object of the present invention is to ultimately solve the problem of shortening the lifetime of the automatic door system, to prevent the waste of driving power energy, and to lower the cost of maintenance and management, and to prevent the loss of indoor thermal energy. It is to provide a automatic door and its operation method.

The present invention also changes the method of applying power to the automatic door driving source from the transformer usage method to the SMPS (Switching Mode Power Supply) method to increase the efficiency of the power, automatic door that is not affected by external power fluctuations. There are other purposes to implement the controller, and the SMPS is embedded in the control board to facilitate installation and maintenance as well as to reduce the size of the product.

In addition, the present invention can provide a terminal for communication to transmit the state and the number of operation of the automatic door to the outside, the automatic door remote control such as opening and closing the automatic door and setting the control parameters as well as several automatic doors If there are, automatic doors communicate with each other to achieve interrelated behavior.

In order to achieve the above objects, the present invention, the forward and reverse rotation drive motor is installed on the installation panel in the door frame; The driving pulley and the driven pulley which are driven by receiving the rotational power from the reducer which receives the rotational power from the driving motor and decelerates at a specific reduction ratio are wound around the driving belt and connected to each of the upper and lower sections of the driving belt. A deceleration / power transmission unit for coupling a pair of door hangers mounted at positions with the upper ends of the doors to decelerate rotational power from the drive motor and to transmit the deceleration / power transmission unit to the doors; Receives the reflected signal from the transmitter sensor member installed at the center of the upper side of the door frame as the receiver sensor member, and calculates / detects the data value of the access traffic in the calculator, and temporarily calculates the arithmetic data value output from the calculator. A body-sensing sensing unit for storing and transmitting the data according to the operation of the data output management unit; A controller for controlling the driving of the drive motor according to the signal detected by the fuselage sensing sensor; Switching mode in which 220V AC current can be converted into 24V DC required for driving the motor and 5V DC required for multiple sensors / processors, respectively, and electrically connected to the inside of the controller while being electrically connected to the power switch. It provides an automatic door controller comprising a power supply unit which is a power supply (SMPS).

The controller provides an automatic door controller, characterized in that the communication port is further provided to communicate with the controller of the other automatic door controller.

The switching mode power supply (SMPS) is composed of an inductor / semiconductor switch / diode and a resistor / capacitor. When the voltage at the 'g' point is about 5V different from the voltage at the 's' point, the 'd' And 's' are electrically connected, when the voltage between points 'g' and 's' is near 0V, 'd' and 's' are electrically disconnected, and the voltage at point 'g' 'D' and 's' are electrically connected when there is a difference of approximately 5V from the voltage at this 's' point, and 'd' and 's' when the voltage between the points 'g' and 's' is near 0V. A switching function is performed in which 's' is electrically disconnected. When the current Vi is applied to the inductor L, the current iL turns on the semiconductor switch dgs, and the current amount is controlled by the inductor L. Increases, the load R consumes the current from the capacitor C, and the inductor L current when the semiconductor switch dgs is turned off. Allow (iL) to be applied to the resistor (R) through the diode, and some current (iL) may be made to charge the capacitor (C).

In addition, in the present invention, the initialization step is executed by starting by turning on the power switch; Inputting and storing an input value from the fuselage sensing sensor; Reading a preset time value corresponding to the input stored value in the step and storing the inputted time in another register; Starting to drive by applying an electrical signal to the drive motor; Starting a time count by operating a timer; Receiving and storing a time value from the timer; Comparing the magnitudes of the input stored values; In the above step, when it is determined that the door opening time has elapsed sufficiently, it provides a method of operating the automatic door controller comprising the step of driving back the drive motor and returning to the initial stage.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a schematic configuration diagram for showing the relationship between the automatic door controller and the automatic door according to the present invention, Figure 4 is a schematic configuration diagram of a wiring state for showing the automatic door controller according to the present invention.

As shown, the present invention relates to an automatic door having an electric door engine (motor), the door engine (drive motor) and deceleration, such that the action of sliding the door closer to one or more doors in accordance with the forward and reverse rotation action of the motor It consists of a power transmission unit, a fuselage sensing sensing unit, and a controller.

That is, the drive motor 14, which can be rotated forward and backward, is mounted on one side of the installation panel 12 in the door frame 10 in combination with the reducer 15 and the drive pulley 16, and driven to correspond to the drive pulley 16. Through the door hangers 22 and 24 at the positions of the upper section and the lower section of the drive belt 20 provided to wind the drive pulley 16 and the driven pulley 18 by installing the pulley 18. The tops of the doors 26 and 28 are mounted.

In addition, the body sensing sensing unit (S) for detecting the entrance and the controller 30 for controlling the driving of the drive motor 14 in accordance with the signal detected by the body sensing sensing unit (S) is further provided. The above-described fuselage sensing sensing unit (S) is installed to emit far infrared rays or ultrasonic waves downward in the center of the upper side of the door frame (10), and is usually a rectangular area of a predetermined width with respect to the floor of the building. It is possible to identify the access body located inside and detect the access traffic at the same time.

That is, it is possible to shoot and emit far infrared rays from the transmitter far infrared sensor member 2, and to receive the far infrared rays reflected by the fuselage in the rectangular area of a certain area with respect to the floor of the building and its bottom, etc. 4) can be accepted to calculate the traffic volume.

In addition, the data value for the amount of access traffic detected / calculated by the calculating section 6 of the fuselage sensing sensing unit S is inputted to the controller 30 by the data output management device 8. The controller 30 calculates the driving control value of the door engine, that is, the driving motor 14 in consideration of the input data value, thereby controlling the opening time and the opening amount of the doors 26 and 28.

The controller 30 may be further provided with a communication port C1 to allow communication between the communication port C1 and the communication port C2 of another automatic door controller controller 30 '.

Therefore, when multiple automatic doors are installed, the traffic volume information is communicated between the automatic doors to maximize the efficiency of opening and closing the door, and remotely performing operations such as opening and closing of automatic doors and setting control parameters through a remote controller (not shown). You may.

In addition, as shown in Figure 4, the power supply unit, the upper end of the door (not shown) in each of the upper and lower sections of the drive belt (not shown) of the belt pulley 16 driven by the forward and reverse rotation motor 14 The same applies to the above automatic doors, each having a fixed door engine.

As well as the automatic door as described above, by detecting the position of the moving position of the door by the position sensor and input to the controller 30, the controller 30 can consider this input information in the opening and closing drive control of the door. Is done.

That is, the door is automatically opened and closed by controlling the driving of the motor 14 by the controller 30 which senses the need for opening and closing as in the prior art.

On the other hand, in the present invention, in order to supply a 24V direct current to the motor 14 drive portion, the alternating current of the power supply 220V must be converted into a 24V direct current, and a plurality of sensors (2) (4) or processor (6) (C) In order to supply 5V direct current, 24V direct current must be stepped down to 5V direct current.

The 24V direct current required to drive the motor 14 as described above is a circuit transformer as shown in FIG. 5 inside the controller 30 electrically connected to the power switch SW (ie, switching mode power supply (SMPS)). It is obtained by pressing down.

In addition, a 5V direct current required for the multiple sensors 2 (4) or the processors 6 (C) is also obtained by stepping down a 24V direct current through the SMPS in the controller 30.

SMPS as described above is shown in FIG. It may be composed of an inductor (L) / semiconductor switch (dgs) / diode and a resistor (R) / capacitor (C).

According to the above configuration, when the voltage at point 'g' is approximately 5V different from the voltage at point 's', 'd' and 's' are electrically connected, and point 'g' and 's' When the voltage between them becomes near 0V, a switching function is performed in which the 'd' and 's' are electrically disconnected.

Therefore, when the voltage at point 'g' is approximately 5V different from the voltage at point 's', 'd' and 's' are electrically connected, and the voltage between points 'g' and 's' is 0V. The switching function is performed in which 'd' and 's' are electrically disconnected when near.

When a constant current Vi is applied to the inductor L, this current iL turns on the semiconductor switch dgs and increases the amount of current by the inductor L, and the load R is the capacitor C. Consumes current from

In addition, when the semiconductor switch dgs is turned off, the inductor L current iL is applied to the resistor R through the diode, and part of the current iL is charged in the capacitor C.

The 24V direct current obtained by the above-described action is applied to the motor 14 driving part, and the 5V direct current required for the multiple sensors 2 (4) or the processors (6) (C) is also switched mode as described above. It is obtained by converting and stepping down 220V of alternating current from the power supply through a switching mode power supply (SMPS).

With reference to the accompanying drawings will be described in detail the operation of the present invention as follows.

6 is a flowchart illustrating a method of operating an automatic door as described above.

In the method of the present invention, first, by simultaneously turning on the power switch, the controller 30 initializes all the registers (S100), and registers the input values from the fuselage sensing sensing unit S which are arbitrarily named. The step S200 of storing the input in 'q' is executed and implemented.

In addition, reading the predetermined time value corresponding to the value of the register 'q' and storing it in a randomly named register 't1' (S300) and applying an electrical signal to the driving motor 14 which is a door engine. The step S400 of starting to drive the driving motor 14 and the step S500 of starting to operate a timer (not shown) built in the controller 30 are continuously executed.

In the step S400 of starting the driving motor 14, for example, the driving motor 14 is driven in the opening direction of the doors 26 and 28.

Next, receiving the time value from the timer as described above and storing it in an arbitrarily named register 't2' (S600), and comparing the magnitudes of the values of the register 't1' and 't2' (S700). In step S700, when it is determined that the size of the value 't1' is smaller than or equal to the size of the value 't2', the driving motor 14 (door engine) is reversely driven. (S800), the return is executed in the initial stage.

That is, it causes the doors 26 and 28 to be opened for a predetermined time with a predetermined opening amount, and immediately after this action is completed, the driving motor 14 (door engine) is reversed in the closing direction of the doors 26 and 28. To drive.

In addition, although not shown, the position position of the doors 26 and 28 may be detected by the position sensor and input to the controller 30 so that the controller 30 may transmit such input information to the doors 26 and 28. Consideration may be given to the opening and closing drive control.

And (not shown) in the case of installing a plurality of automatic doors by further executing the communication step and remote control step, the traffic volume information is communicated between the automatic doors to maximize the efficiency of the door opening and closing, automatic through the remote control controller (not shown) You can also remotely perform operations such as opening and closing doors and setting control parameters.

As described above, the automatic door controller and the drive control method thereof according to the present invention, in consideration of the calculation of the time value for detecting the access traffic volume and maintaining the detected value in the open state and the calculation of the value for the opening amount of the door, It provides the effect that the door is not opened more than necessary depending on the amount of traffic.

For example, if there is a large amount of entrance and exit traffic, the door is kept open for a time until all the people pass through the door, thereby avoiding opening and closing the door repeatedly.

This operation not only reduces the lifetime of the automatic door system, but also saves the driving power energy by that amount, and also reduces the cost of maintenance and management.

On the contrary, the problem of leaving the door open for an unnecessarily long time, even if the entry and exit traffic volume is very small, is solved. Opening only as much as possible to further prevent the loss of thermal energy, as well as to prevent the waste of power energy.

The present invention described as described above is merely a preferred embodiment, and the scope of the present invention is not limited to the above, but may be appropriately changed within the scope of the same idea.
