A door is a movable part composed of a door and a door frame, and serves to close one area. In particular, since the entrance door of the home or the entrance of the office is provided between the indoor space and the outdoor space, it is important that safety and robustness are maintained in order to prevent intrusion of the outsider and protect the indoor space.

However, since the entrance door of the home or the entrance of the office is mainly made of a heavy metal material, the accident occurs frequently during the closing process.

In addition, there is a problem among neighbors due to the noise generated in the process of closing the front door in a multi-family house or apartment house.

Also, since the entrance door of the home or the office is provided between the indoor space and the outdoor space, it is an important factor to lower the efficiency of the cooling and heating energy due to the movement of the air through the door.

Door closers are usually installed at the entrance doors of the homes (especially apartments and office buildings) and offices. Door closer is a device that automatically closes an open door. It consists of a combination of a metal spring and an oil damper. By adjusting the speed control valve clockwise or counterclockwise using a driver or a coin, .

Applicants have been studying a device capable of automatically adjusting the speed control valve of a door closure to solve the energy efficiency problem, the safety accident problem, and the noise problem described above.

Referring to FIG. 1, generally, two door regulating valves V1 and V2 are formed on a door closer DC.

6, one of the two speed-regulating valves V is a primary section in which the internal resistance of the door closer DC is large, that is, the door opening angle alpha is in a range of 0 to 10 degrees, And the other one of the two speed-regulating valves V is a secondary section having a small internal resistance of the door closer DC, that is, a door opening angle alpha of 10 degrees to 180 degrees This is to change the internal resistance small or large.

As described above, since the resistance of the secondary section is smaller than the resistance of the primary section, the door closure (DC) can not be modeled as a continuous type of attenuation motion and should be approached by two-stage modeling.

That is, in the secondary section having a small resistance, the rotational motion of the hinged door (D) must be modeled as a damping motion, and in the first section having a large resistance, the rotational motion of the hinged door (D) . FIG. 7 (a) shows a graph in which the underexposure motion and the excessive damping motion of the door closer DC are overlapped. FIG. 7 (b) It shows the graph.

As described above, the door D provided with the door closer DC is rotated at different speeds in the primary section and the secondary section by two attenuating movements of the door closer DC. Therefore, depending on how the two speed control valves V1 and V2 are adjusted, the amount of heat energy flowing through the open space of the door, the size of the noise generated when the door is closed, and the possibility of a safety accident are determined. The applicant of the present invention has proposed an automatic regulating device 1 for reducing the amount of heating energy escaping through the door D to a minimum by minimizing the size of the noise and the possibility of a safety accident through the automatic adjustment of the speed- ) And its control method (S100).

First, the present applicant conducted the first experiment using only the door opening angle as a variable.

The temperature change was measured by using a thermal camera to determine the temperature at which the temperature changes at the moment of closing the door. As a result, the distance was 0.8 m. Using a MBL (Microcomputer-Based Laboratory) PT temperature sensor with an error of ± 0.1 ° C, eight units were installed, four each at 0.2 m intervals inside and outside the door.

In the noise measurement, five noise measuring machines with an error of ± 1.5dB were installed at intervals of 0.5m on the inside of the door, and one was installed at the same position in the upper and lower layers.

We used a load cell to measure the closing force of the door. Two load cell units with error ± 0.1N were installed at the middle of the door gap and at the middle height of the door gap.

The door closing time was measured using a GOPRO camera with an error of ± 0.01 sec.

The speed of the door was measured using a speed meter with an error of ± 0.01m / s. The speed was measured by attaching a rod to the door and passing through the speed meter.

And it was possible to measure the movement of minute heat by using the thermal camera. The thermal imaging camera was photographed by the door as the GOPRO camera. In particular, it was possible to logically determine the interval of the PT temperature sensor by letting the temperature change to a certain distance at the moment of closing the door.

Fig. 8 (a) is a temperature distribution diagram of a door taken by a thermal imaging camera. It can be seen that the temperature actually varies up to 0.8 m. 8 (b) shows an experimental model designed by CAD. Noise level meter, MBL PT temperature sensor, load cell, and speed meter. 8 (c) is a photograph of an actual test scene. The experimental equipment was used equally in the second experiment.

The first experiment was conducted according to the open angle of the door (30 °, 45 °, 60 °, 90 °). First, 40 experiments were repeated 10 times for each angle. Next, the experiment was repeated for every experiment in which a measurement error occurred in order to correct the measurement error.

9 (a) is a graph in which the noise, door closing time, and door closing amount are measured with the door opening angle (30 degrees, 45 degrees, 60 degrees, 90 degrees) 30 degrees, 45 degrees, 60 degrees, and 90 degrees).

As shown in Figs. 9 (a) and 9 (b), before the first experiment, the angle was expected to be an important factor for changing noise, heat loss, and power. All the results were proportional to the angle and did not satisfy all optimization conditions. Therefore, we have planned a second experiment to change the resistance adjustment setting.

The second experiment was to fix the door opening angle of 60 degrees, which is the most open and closed angle of the people, and to set the resistance control of the speed control valve for the first section of the door closure in the order of resistance 1 ~ 6, .

First, we repeated the experiment five times for each resistance adjustment setting, and then performed a total of 30 experiments. After that, the experiment was repeated for each experiment in which a measurement error occurred in order to correct the measurement error from the first experiment. 10 (a) and 10 (b) show the results of the second experiment.

10 (a) is a graph showing noise, door closing time, and door closing impulse with the variable resistance setting of the speed regulating valve for the primary section, FIG. 10 (b) And the force of closing the door is measured.

As shown in Figs. 10 (a) and 10 (b), the second experiment showed that the optimization condition that the temperature change, the noise and the power were all minimized was not obtained. However, The resistance of 6 steps representing the minimum value and the step of 2 different resistance are the closest to the optimization conditions for all variables.

As shown in Figs. 10 (a) and 10 (b), the tendency of the data of the two kinds of data of door closing time, temperature change, noise change and force is quite similar . ≪ / RTI >

As the door closing time increases, the movement of air through the open part increases and the temperature change increases. The greater the change of the noise, the larger the angular momentum of the door is lost due to the collision with the door opening. That is, it can be explained that the door closing time, the temperature change, the noise change and the force tend to be the same.

Door closing time, temperature change, noise change and force, ie, all four parameters, are closely related to optimization conditions. However, it is not easy to use MBL PT temperature sensor or load cell in real life, load cell can be easily damaged by impact, and temperature measurement through MBL PT temperature sensor is difficult to measure due to variables such as window opening. And door closing time and noise with different tendencies are considered to be suitable parameters for setting the criteria of the optimization condition.

Also, since the door closing time, the temperature change, the noise change and the force show the same tendency, the optimization condition can be judged only by the door closing time and the noise change.

However, the door closing amount can be set as a parameter. That is, the load cell may be installed at a position where the door and the door frame collide with each other to measure an amount of door closing impact and set an optimal resistance stage of the door closure as a variable.

A more detailed description of the above-described experiments is disclosed in the development of a smart green door buffer that minimizes thermal energy loss, noise, and safety accidents using analysis of damping harmonic motion, which was published on March 28, 2015.

1 and 3, the door closing automatic control apparatus 1 of the present invention is a door closing automatic control apparatus for a door closing door And includes a sensor unit 10, an adjustment unit 20, and a control unit 30. The sensor unit 10, the adjustment unit 20,

1 and 2, the sensor unit 10, the adjusting unit 20 and the control unit 30 are installed inside the case C, and the case C is provided near the door closer DC, Respectively. The case C is made of a synthetic resin or a metal material, and is preferably formed in a rectangular parallelepiped shape.

The sensor unit 10 is configured to measure at least one of a door opening angle and a door closing time and door closing amount during opening and closing of the hinged door D. In an embodiment of the present invention, ) And an acoustic sensor 12 to measure noise and gate closing time.

The distance sensor 11 is configured to measure the distance between the hinged door D and the fixed object, and an ultrasonic sensor or an infrared sensor can be used. Fig. 1 shows an ultrasonic sensor as the distance sensor 11. Fig.

6, the distance sensor 11 is provided for measuring the rotation distance of the door when opening and closing the hinged door D, and the distance sensor 11, D are opened and closed and are arranged to measure the distance in the rotating direction.

As shown in Fig. 4, the distance sensor 11 preferably measures the normal direction distance from the surface where the door closer DC is installed to the fixed object. 3 and 4, a bracket B for reflecting the infrared rays or the ultrasonic waves of the distance sensor 11 may be attached to the door frame F, It is desirable to install it.

The infrared or ultrasound waves output from the output section 11A of the distance sensor 11 are reflected toward the input section 11B of the distance sensor 11 after colliding with the bracket B and the control section 30 is irradiated with ultraviolet The distance between the door and the bracket B is calculated through the time difference between the output signal of the door and the input signal and the distance between the door and the bracket B is substituted into the trigonometric function to calculate the rotation angle of the hinged door D.

That is, since the infrared ray or the ultrasonic wave is outputted from the hinge door D in the normal direction, the controller 30 controls the distance from the rotation axis of the hinge door D to the distance sensor 11, B is substituted into the trigonometric function to calculate the rotation angle of the sliding door D.

The acoustic sensor 12 is configured to measure the noise when the hinged door D is closed so that the hinged door D is exposed from the case C toward the opposite side or the bottom of the rotary shaft connected rotatably with the door frame F . 3 and 4, the acoustic sensor 12 is shown exposed to the bottom.

The control unit 30 continuously receives the input signal of the distance sensor 11 to determine whether the opening and closing of the sliding door D is opened or closed by increasing or decreasing the input signal, Is stored as noise due to the closing of the sliding door (D).

The control unit 30 stores the door opening angle of the door D calculated at a point where the input signal increases and then decreases. The control unit 30 calculates the time taken from the point at which the input signal increases to the point at which the door closes And stored as door closing time.

1 and 2, the adjustment unit 20 is configured to adjust the speed control valve V of the door closer DC installed on the hinged door D, and includes a servomotor M and a coupler U ).

1 shows a state where the control unit 30 and the servo motor M are coupled to the mounting plate A1 and the mounting plate A1 is coupled to the heat dissipating plate A2 on the opposite side of the control unit 30. [ The heat dissipating plate A2 is coupled to the case C and the heat of the control unit 30 is quickly discharged to the hinged door D through the mounting plate A1, the heat dissipating plate A2 and the case C.

The servo motor M is configured to generate a rotational force for rotating the speed control valve V, and the rotational angle is controlled by the control unit 30. [

Generally, in the door closer (DC), in the primary section (10 degrees at the door opening angle of 0 degrees) and the secondary section (180 degrees at the door opening angle of 10 degrees) Two speed regulating valves V1 and V2, namely, a first speed regulating valve V1 and a second speed regulating valve V2 are formed to adjust the rotational speeds respectively. 1 and 2 show a first servo motor M1 for adjusting the first speed regulating valve V1 and a second servo motor M2 for regulating the second speed regulating valve V2.

Of course, since the door closer DC having only one speed control valve V is distributed in the market, it is also possible to produce a product in which only a single servomotor M is installed at the time of manufacturing the automatic adjustment device 1. [ The first servo motor M1 and the second servo motor M2 are controlled by changing the setting of the control unit 30 so as to drive only one servo motor M of the first servo motor M1 and the second servo motor M2 M2 may be used as it is. The setting of the control unit 30 can be performed by connection to the Ardino via the personal PC.

The intervals between the rotating shafts of the first servomotor M1 and the second servomotor M2 are arranged at the same intervals as the intervals between the first speed control valve V1 and the second speed control valve V2.

The case C is a case in which the rotary shaft of the first servomotor M1 and the second servomotor M2 is in the state of facing the first speed regulation valve V1 and the second speed regulation valve V2 . Although not shown, through-holes (not shown) to be fastened with bolts are formed on the hinged door D in the case (C).

As shown in Figs. 1 and 5, the coupler U has a structure in which the servo motor M and the speed control valve V are rotated in conjunction with each other, A groove H1 is formed and a projection P inserted into the groove of the speed control valve V is formed at the other end.

The coupling groove H1 and the projection P formed in the coupler U are formed in the shape of the rotary shaft of the servo motor M and the shape of the groove formed in the speed adjusting valve V It can be manufactured variously according to the shape.

Although not shown, the coupler U may be formed of a flexible material in the middle, or may be formed of a universal joint or a ball joint.

Even if the coupler U is formed of a flexible material in the middle or is formed of a universal joint or a ball joint so that the servo motor M and the speed control valve V are not aligned with each other, The speed control valve V can be rotated. The other end of the coupler U may be fixed to the speed control valve V by welding or the like so that the projecting portion P does not deviate from the groove of the speed control valve V. [

1 and 2, the control unit 30 stores and analyzes the data measured by the sensor unit 10 to perform driving of the adjustment unit 20 so as to minimize noise during opening and closing of the sliding door D And is provided with a micro controller such as Arduino.

Arduino is a single-board microcontroller based on open source and is a complete board and related development tools and environment. Arduino is easy to create devices that can interact with the environment by taking the values from multiple switches or sensors and controlling external electronic devices such as servo motors (M).

Arduino is one of the embedded systems and controls the devices using an environment that can be easily developed. As a known technique, a detailed description thereof will be omitted.

Hereinafter, a control method (S100) of the automatic door closing apparatus of the present invention will be described in detail.

As shown in FIG. 11, a control method (S100) of a door closer automatic control apparatus according to an embodiment of the present invention includes a pre-storing step (S110) and a valve adjusting step (S120).

The control method S100 of the door closing automatic control device is started when the door closing automatic control device 1 is installed on the hinged door D as shown in Fig. 3, and below the two speed control valves V1 , V2) as a door closer.

The pre-storing step S110 is a step of measuring and storing one or more data among the noise, door closing time and door closing amount of the door through the sensor unit 10 while the door opening degree D is opened and closed N times In the control method (S100) of the door closer automatic control apparatus according to the embodiment of the present invention, the sensor unit 10 detects the door opening angle and the noise and door closing degree through the distance sensor 11 and the acoustic sensor 12, I will explain it by measuring time.

In the pre-storing step S110, the controller 30 adjusts the two speed control valves V1 and V2 by M stages through the driving of the adjusting unit 20, and adjusts the noise and door closing time And the distance sensor 11 and the acoustic sensor 12 of the sensor unit 10 and stores the measured data.

In the pre-storing step S110, the number N of opening and closing of the hinged door D means a plurality of times that data of the noise and door closing time can be sufficiently obtained for each door opening angle. And the number of door opening angle sections.

The adjusting step of the speed adjusting valve V means the number of resistance steps of the speed adjusting valve V varying through the driving part. For example, the first speed adjusting valve V1 and the second speed adjusting valve V2, Can be adjusted in six stages through the driving unit.

That is, the resistance of the door closure DC, which is changed by the pair of speed control valves V1 and V2, is adjusted from the first stage to the sixth stage through the rotation of the driving unit. Of course, the steps of the pair of speed control valves (V1, V2) can be changed at any time in addition to six stages.

The number of door opening angle sections is for determining the adjustment amount of the speed control valve V that minimizes noise generation at different door opening angles at which the hinged door D is opened. For example, Can be selected at intervals of 10 degrees. That is, the control unit 30 determines the amount of adjustment of the speed control valve V that minimizes the noise generation for each of the opening intervals of the total of nine doors from 0 to 90 degrees.

In the case where the adjustment steps of the pair of speed control valves V1 and V2 are respectively set to six stages and the door opening angle section is selected in nine sections in total, in the pre-storing step S110, N times is preferably about 1000 times.

The Applicant has found through the first experiment and the second experiment that the absolute values of noise, door closing time, temperature and force in the pre-storage step (S110) show a tendency to increase with door opening angle (see FIG. 9) It was confirmed that at the same door opening angle, the resistance level of the first speed regulating valve V1 was distributed by a specific trend (see FIG. 10).

Although not shown, when the resistance value of the second speed regulating valve V2 is used as a variable at the same door opening angle, it is confirmed that the absolute value is slightly increased or decreased, but the trend of FIG. 10 is maintained.

10, when the resistance of the first section of the door closer DC is adjusted to six levels through the adjustment of the first speed control valve V1 at the door opening angle of 60 degrees, the noise and force The temperature change was measured close to the minimum value.

Therefore, the first speed regulating valve (V1) must be adjusted to the two-stage resistance in order to minimize the noise and the force at a door opening angle of 60 degrees so that the temperature change approaches the minimum value.

Even though the door closers (DC) are produced by different manufacturers, the principle of forming the resistance of the primary section and the secondary section different from each other by using elasticity and hydraulic pressure of the spring is the same,

The pre-storing step (S110) may be preliminarily inputted at the time of manufacturing the automatic adjusting apparatus (1). That is, when the automatic adjustment device 1 is pre-stored (S110) for each of a plurality of door closers (DC) produced by different manufacturers and sold in a state in which it is input to the controller 30, It is only necessary to select the door closer (DC) installed in the sliding door (D) by connecting to the Arduino via the personal PC.

The valve adjusting step S120 is a step of controlling the driving of the adjusting unit 20 so as to minimize the noise by predicting the next door opening angle by analyzing the data stored in the control unit 30 at the time of opening and closing N times of the door D , An additional storing step (S121), and a correction adjusting step (S122).

The next door opening angle is selected as the most open door opening angle (or the average value of the stored data) of the door opening angle of the stored data. The door opening angle may be different depending on the habit of opening the door of the residence or the surrounding environment interfering with the opening angle of the door. In general, the door opening (D) is predicted to be about 60 degrees There is a high probability.

The additional storing step S121 is a step of storing the data of the noise and the door closing time through the sensor unit 10 together with the door opening angle of the control unit 30 at the time of opening and closing of the sliding door D after the pre- , The data stored in the additional storing step S121 is used to correct the driving of the adjusting unit 20 in the correction adjusting step S122.

The door closures (DC) can change the mechanical operating performance due to the friction between the components over time that is used as a mechanical device. As a result, due to the leakage of oil or the formation of deposits in oil, The data of the closing time may also change.

In the correction adjustment step S122, the control unit 30 analyzes the data of the additional storage step S121 together with the data of the data storage step to predict the door opening angle when the sliding door D is opened next time, As a step of controlling the driving of the adjustment unit 20, data on the door opening angle at which the sliding door D is opened and closed next is corrected through data construction in the correction adjustment step S122.

Further, even if the absolute value of the noise and door closing time for the door opening angle changes due to the change of the mechanical properties of the door closer (DC) or the leakage of the oil or formation of precipitates in the oil, Even if the performance of the door closer DC is changed by correcting the noise and the door closing time data, the automatic door closing apparatus 1 of the present invention maintains the occurrence of noise and safety accidents to a minimum, As shown in FIG.

According to the present invention, the speed control valve (V) of the door closure (DC) installed on the hinged door (D) is automatically adjusted so as to minimize noise during opening and closing of the hinged door (D) It reduces the amount of air that escapes through the hinged door (D) while minimizing the noise generated when the door (D) is closed, and prevents accidents caused by the body being caught when the hinged door (D) is closed It is possible to provide a door closer automatic controlling apparatus 1 and a control method thereof (S100).

Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
