1 is a conceptual diagram of an IoT-based opening and closing system according to an embodiment of the present invention.

Referring to FIG. 1, an IoT-based opening and closing system 1000 according to an embodiment of the present invention may include an IoT-based opening and closing device 200 and a user terminal 100.

The user terminal 100 is a device capable of communication and input/output of information, and may be implemented as, for example, a PC, a smartphone, a tablet, etc., and a software (application) that provides an automatic door opening service is installed. Can be implemented.

The user terminal 100 may transmit and receive information for implementing an automatic door opening/closing service with the IoT-based opening and closing device 200. For example, the user terminal 100 may remotely manually control the opening and closing of the door by transmitting a door opening or closing signal to the IoT-based opening and closing device 200. Alternatively, the user terminal 100 may receive sensing information inside and outside the door from the IoT-based opening and closing device 200. Alternatively, the user terminal 100 may receive various related service information according to sensing information inside and outside the door from the IoT-based opening and closing device 200. The IoT-based opening/closing device 200 may refer to the door itself for inputting and outputting electrical signals. In addition, the above-described or later-described door means all structures that can be opened and closed, such as doors and windows.

The IoT-based opening and closing device 200 may be installed on one side of the door to implement an automatic door opening and closing service in which the user terminal 100 participates.

In this embodiment, the door may be a door or a window capable of automatically opening and closing, and may be a sliding door as shown in FIG. 1.

For example, a door has a door frame frame with an upper and lower sliding rail inside and an installation space formed at the top, and a plurality of doors installed to slide left and right by motor driving along the sliding rail of the door frame frame. It can be composed of. Here, the door frame frame constituting the door may be made of a plastic sheet according to the plastic sheet manufacturing method according to an embodiment of the present invention as follows.

The method for manufacturing a plastic sheet according to an embodiment of the present invention includes 100 parts by weight of a polyethylene telephthalate (PET) resin, 2 to 4 parts by weight of a polyurethane dispersant, and polyethylene dioxythiophene polystyrene sulfonate. polystyrene sulfonate) 0.1 to 0.2 parts by weight, polystyrolsulfonic acid, N-methyl-2-pyrrolidone 3 to 5 parts by weight, triethyl amine 0.1 A first step of preparing a mixed composition by mixing ~0.3 parts by weight, 42 to 45 parts by weight of isopropyl alcohol and 50 to 52 parts by weight of water; A second step of preheating the mixed composition; A third step of removing moisture from the preheated mixed composition; A fourth step of heating the mixed composition from which moisture has been removed; A fifth step of removing foreign substances from the heated mixed composition; A sixth step of preparing a plastic sheet by stretching the mixed composition from which the foreign substances are removed while cooling; And a seventh step of drying after applying the silicone to the plastic sheet. According to the present invention, a plastic sheet having excellent moldability and durability can be prepared by mixing various additives with a conventional PET resin, and preheating, dehumidifying, heating and cooling.

The first step is a mixing step of raw materials, using a polyethylene telephthalate (PET) resin as the base resin, a polyurethane dispersant, a polyethylene dioxythiophene polystyrene sulfonate, and a police. This is a step of mixing polystyrolsulfonic acid, N-methyl-2-pyrrolidone, triethyl amine, isopropyl alcohol, and water.

PET resin, as a base resin, has excellent thermal stability and high crystallinity, can be recycled, and is manufactured in the form of a master batch. Polyurethane dispersants function to improve miscibility with other ingredients. Polyethylene dioxythiophene polystyrene sulfonate, polystyrolsulfonic acid, N-methyl-2-pyrrolidone and triethyl amine Functions as an antistatic agent. Since plastic sheets for manufacturing plastic containers are generally electrical insulators, static electricity is generated due to frictional charging, and severe discharge or electrical conduction can lead to accidents such as explosions and fires, so it is preferable to add a charging agent. . Isopropyl alcohol functions as an antifogging agent. The antifogging agent can suppress the formation of water droplets caused by water vapor that may occur when manufacturing plastic containers or storing fruits, etc. by using a plastic sheet.

As an example, the above-described raw materials are, based on 100 parts by weight of a polyethylene telephthalate (PET) resin, 2 to 4 parts by weight of a polyurethane dispersant, polyethylene dioxythiophene polystyrene sulfonate 0.1 ~0.2 parts by weight, polystyrolsulfonic acid (polystyrolsulfonic acid) 0.4 to 0.6 parts by weight, N-methyl-2-pyrrolidone (N-methyl-2-pyrrolidone) 3 to 5 parts by weight, triethyl amine It is preferable to mix 0.1 to 0.3 parts by weight, 42 to 45 parts by weight of isopropyl alcohol, and 50 to 52 parts by weight of water. When added outside the above-described range, various problems may occur. In particular, in the case of the antistatic agent, when mixed beyond each range, the surface of the plastic to be produced may be sticky, sealing properties and printability may be deteriorated, and in the case of white plastic, yellowing may occur.

In addition, in the first step, various additional components may be further mixed with the raw materials to enhance the functionality of the plastic sheet.

For example, a boron-based binder may be further mixed. The boron (B)-based binder is used to combine each component, and the boron-based binder is preferably mixed in an amount of 2 to 10 parts by weight based on 100 parts by weight of the PET resin. When the content of the boron-based binder is less than 2 parts by weight, raw materials and the like cannot be effectively combined, and when the content of the boron-based binder exceeds 70 parts by weight, it is uneconomical.

For example, garlic extract may be further mixed. Garlic extract is a natural adhesive component, and functions as a binder that improves miscibility with other constituents together with a boron-based binder. The garlic extract is peeled and pulverized, and then 2-3 parts by weight of water are added per 1 part by weight of garlic, heated at 80-100°C for 5 hours or more, and then the liquid component is extracted and filtered. It can be prepared by concentrating the liquid component at 55~60℃. The garlic extract is preferably mixed in 5 to 10 parts by weight based on 100 parts by weight of the PET resin. If the content of the garlic extract is less than 5 parts by weight, the raw materials cannot be properly entangled and thus the surface may not be formed evenly during the manufacture of the plastic sheet.If it exceeds 10 parts by weight, the dispersibility and mixing properties of each component are rather There is a risk of deterioration.

For example, apatite powder may be further mixed. Apatite powder functions as a filler, and maintains the shape of a plastic sheet to improve workability, maintain strength, and improve corrosion resistance. Apatite is an inorganic material that exists in bones, and in order to use it as a filler, it is important to have a small particle size, high residual amount of carbonic acid, and low crystallinity. Preferably, the size of the apatite granules is 200 to 400 μm. For this, it is important to go through the sintering process at 500~700℃. When sintering at less than 500°C, there is a disadvantage that the size and crystallinity of the desired granules cannot be obtained, and when sintering exceeding 700°C, the residual amount of carbonic acid groups is low, and the crystallinity is too high. The apatite powder is preferably mixed in an amount of 20 to 30 parts by weight based on 100 parts by weight of the PET resin. When the content of the apatite powder is less than 20 parts by weight, there is a disadvantage of lowering the adhesive strength, and when it exceeds 30 parts by weight, there is a disadvantage that the impact resistance is weakened.

For example, cork powder may be further mixed. Cork powder can improve the durability of the plastic sheet together with the apatite powder. Cork powder can be prepared by removing the bark of the oyster oak and pulverizing it. It is preferable to use finely pulverized particles filtered through a mesh of 400 mesh or more in order to mix the cork powder with PET resin. The cork powder is preferably mixed in an amount of 15 to 25 parts by weight based on 100 parts by weight of the PET resin. When the cork powder is less than 15 parts by weight, the degree of improvement in durability is insignificant, and when it exceeds 25 parts by weight, voids may be formed inside the plastic during manufacture, so durability may be rather degraded.

As an example, it is possible to further mix the extract of the herringbone. Conch extract not only acts as an antibacterial agent, but can also suppress the yellowing phenomenon that may occur in white plastic sheets. Rumex crispus is a plant of the genus Rumex of the family Rumex that grows wild in Korea. Hermitage is a perennial plant that grows well in humid places in various places. The private use of young shoots for food. In oriental medicine, it is called yangje, and it It is used as an adjuvant treatment for tumors or cancer. Conch extract extracted from conch has antibacterial and antioxidant effects against various microorganisms, and when used in combination with a small amount of sulfur, it has an excellent effect on skin itching. It is reported that known useful ingredients of sori chinensis include saponins, tannins, flavonoids, essential oils, and anthraquinone derivatives such as chrysophanol and emodin. After washing the collected conch extract well, it is dried in the shade, divided into above-ground (parts excluding roots) and underground (roots), and then cut into 80% (v/v) methanol as an extraction solvent for 3 days. After immersion, the extract may be filtered through a membrane filter (porosity of 0.5 μm) to separate the solid, and the methanol extract may be concentrated at 50° C. using a rotary evaporator. It is preferable to mix the conch extract in 3 to 8 parts by weight based on 100 parts by weight of the PET resin. When the content of the conch extract is less than 3 parts by weight, the anti-yellowing effect is insignificant, and when it exceeds 8 parts by weight, it is uneconomical.

The second step is a step of preheating the mixed composition, in which heat is applied to the mixed raw materials so that the raw materials are first stably mixed.

The third step is a dehumidification step of removing moisture present in the preheated mixed composition, and the dehumidification is preferably performed in a temperature range of 150 to 180°C. If it is less than or exceeds the above range, dehumidification may not be sufficiently performed or may adversely affect the durability of the plastic.

The fourth step is a step of heating the mixed composition from which moisture has been removed, and after melting the mixed composition, the heating temperature is preferably controlled to 260 to 270°C in order to maintain.

The fifth step is a step of removing foreign substances from the heated mixed composition. By passing through a mesh-shaped screen, foreign substances that are problematic inside the mixed composition may be removed.

The sixth step is a step of producing a plastic sheet by stretching while cooling the mixed composition from which foreign matters have been removed, and stretching in two stages using a cooling roll. The primary stretching is performed in the longitudinal direction through a cooling roll maintained at 16 to 17°C, and the secondary stretching is performed in the width direction (vertical direction in the longitudinal direction) through a cooling roll maintained at 20 to 23°C. The reason for raising the temperature of the secondary stretching than the primary stretching temperature is to prevent the plastic sheet to be solidified from becoming inferior in formability by curling, and improving the durability and formability of the plastic sheet by alternately stretching the longitudinal and transverse directions. I can make it.

The seventh step is a step of applying silicone to the plastic sheet and then drying it. The antistatic effect can be obtained at the same time as finishing treatment by applying silicone. Silicone is preferably applied using a coating solution diluted in a concentration range of 5 to 25%, and dried at 160 to 215°C after applying the silicon. In addition, it is preferable to mix the above-described antifogging agent component in the coating liquid containing silicone in order to suppress the phenomenon of moisture formed inside the manufactured plastic container.

The configuration of the communication unit 210, the sensor unit 230, the control unit 250, the display unit 270, and the driving unit 290 shown in FIG. 2 may be formed as an integrated module or may be formed of one or more modules. However, on the contrary, each component may be formed as a separate module.

The IoT-based opening and closing device 200 according to an embodiment of the present invention may have mobility or may be fixed. The IoT-based switching device 200 according to an embodiment of the present invention may be in the form of a server or an engine, and may be a device, an apparatus, a terminal, and a user equipment (UE). ), MS (mobile station), wireless device (wireless device), handheld device (handheld device) may be referred to as other terms.

Hereinafter, each configuration of the IoT-based opening and closing device 200 according to an embodiment of the present invention shown in FIG. 2 will be described in detail.

The communication unit 210 enables wireless communication of the IoT-based switching device 200, and for this purpose, it may be implemented by including one or more components enabling wireless communication. For example, the communication unit 210 may be implemented by including a component that enables at least one communication among Bluetooth, Wi-Fi, 3G, 4G, and 5G. Accordingly, the communication unit 210 may transmit and receive information for providing an automatic door opening/closing service with the user terminal 100 illustrated in FIG. 1.

The sensor unit 230 may be implemented by including at least one IoT sensor for sensing internal and external environment information of the door.

For example, the sensor unit 230 may include a rain detection sensor to detect raindrops outside the door. The rain detection sensor may detect raindrops on the outside of the door by measuring the refraction and reflection amount of water droplets of LED light emission or by detecting a voltage change according to the amount of moisture on the sensing surface. The sensor unit 230 may generate sensor data that can regard rain situation information from the rain detection sensor and transmit it to the controller 250 to be described later.

In addition, the sensor unit 230 may include a fine dust sensor to detect fine dust inside and outside the door. The fine dust sensor can express the amount of the LED emitted light reaching the light receiving unit as a voltage value. The sensor unit 230 may generate sensor data that can consider the value of the fine dust from the fine dust sensor and transmit it to the controller 250 to be described later.

In addition, the sensor unit 230 may include a temperature sensor to detect the temperature inside and outside the door. The temperature sensor can detect a change in temperature using the thermistor resistance. The sensor unit 230 may generate sensor data for confirming the temperature change of the interior and exterior environment of the door from the temperature sensor and transmit it to the controller 250 to be described later.

In addition, the sensor unit 230 may include a radon detection sensor to detect radon inside and outside the door. The radon detection sensor can detect radon concentration by analyzing statistical values such as frequency and pulse count of particles generated from radioactive decay of radon. The sensor unit 230 may generate sensor data for confirming the radon level in the interior and exterior environment of the door from the radon detection sensor and transmit it to the controller 250 to be described later.

The sensor unit 230 may provide information on the internal and external environment of the door to the user terminal 100 through the communication unit 210. Alternatively, the sensor unit 230 may output information on the interior and exterior environment of the door through the display unit 270 to be described later, and provide the information so that the user can check it.

The controller 250 may control the overall operation of the IoT-based opening and closing device 200. In particular, the controller 250 can provide a user-customized automatic door opening/closing service according to the interior and exterior environment of the door by learning sensor data of the interior and exterior environment of the door acquired by the sensor unit 230 and automatic door control information of the user. have. To this end, the control unit 250 may include a learning unit 251 and a linked service providing unit 255.

The learning unit 251 may learn a user's door opening/closing preference condition according to sensor data of an internal/external environment of the door acquired by the sensor unit 230.

In this embodiment, the door is a door capable of automatically opening and closing as described above, and may be automatically opened and closed by a driving unit 290 to be described later. For example, the user can control the door to open and close by directly manipulating the driving unit 290 to be described later. Alternatively, the door may be opened and closed by remotely manipulating the driving unit 290 through the user terminal 100 held by the user.

When the door is opened or closed in this way, the learning unit 251 may learn by matching sensor data acquired by the sensor unit 230 at a corresponding time point. When the door is opened or closed by a user's manipulation, the learning unit 251 may check a rainy weather situation, a fine dust level, a temperature, a radon level, and the like at a corresponding time point.

From this, the learning unit 251 may set a range of rain conditions, fine dust values, temperature, radon values, etc. corresponding to the opening or closing time of the door that the user prefers. For example, the learning unit 251 may set the user's door opening/closing preference condition by averaging the rainy conditions, fine dust values, temperature, radon values, etc. when the user opens or closes the door.

Here, the learning unit 251 may set a door opening/closing preference condition for each family member. For example, the learning unit 251 may acquire identification information of family members through other IoT sensors inside and outside the door, for example, a camera, and learn the door opening/closing preference condition for each family member. In this case, even if only the elderly are present in the house, safety can be ensured by allowing smooth ventilation through automatic door opening/closing control according to environmental information.

The learning unit 251 may collect sensor data obtained from the sensor unit 230 and automatically control the opening or closing of the door when the sensor data satisfies the user's preference for opening and closing the door. Alternatively, the learning unit 251 may automatically control the opening or closing of the door only when a door open/close permission request signal is transmitted to the user terminal 100 and a door open/close permission signal is received in response thereto. Alternatively, the learning unit 251 may provide only information informing the user terminal 100 that the user's door opening/closing preference condition is met to the current interior and exterior environment of the door.

In addition, the learning unit 251 may set a door open/close condition in advance, and automatically control the opening or closing of the door when sensor data collected by the sensor unit 230 satisfies the door open/close condition. Here, the door open/close condition may be set by the user. Alternatively, the door opening/closing condition may be set in advance as a rainy weather situation, fine dust level, temperature, radon level, etc. that generally require the door to be opened or closed.

The linked service providing unit 255 may provide an additional service according to sensor data of an internal and external environment of the door acquired by the sensor unit 230.

The linked service provider 255 may analyze sensor data of the interior and exterior environment of the door acquired by the sensor unit 230 for a predetermined period of time, and obtain environmental characteristics of a corresponding region. For example, the linked service providing unit 255 may confirm that the area is a hot and humid area from sensor data such as a rainy weather condition and temperature.

The linked service provider 255 may search for additional services according to environmental characteristics. The linked service providing unit 255 accesses a separate additional service search engine to search for an additional service according to environmental characteristics, and transmits it to the user terminal 100, or outputs it to the display unit 270, which will be described later, for user confirmation. It can be provided as possible. For example, when it is confirmed that it is a rainy weather, the linked service providing unit 255 may search for a delivery food with high sales or a related marketing in the rain and provide it to the user. Alternatively, when it is determined that the temperature is low, the linked service providing unit 255 may search for cold weather products, heating devices, and the like and provide them to the user. Alternatively, the linked service providing unit 255 may provide a living health management solution according to the monitoring result of the overall residential environment. For example, the linked service providing unit 255 may provide an air purifier rental service when the fine dust level is high. In this way, the linked service provider 255 can build a management platform for overall housing that combines healthcare and home care, and builds big data by accumulating records of environmental characteristics and users' use of linked services, and uses them to make profits. In addition, the linked service providing unit 255 may check the life characteristics of the user according to the user's door opening/closing preference condition learned by the learning unit 251. For example, the linked service providing unit 255 may check the temperature condition at the time of closing the door and predict whether the user is a cold type by comparing it with a preset temperature standard.

The linked service provider 255 may search for an additional service according to a user's life characteristics. The linked service providing unit 255 accesses a separate additional service search engine to search for an additional service according to the characteristics of life, and transmits it to the user terminal 100 or outputs it to the display unit 270 to be described later for user confirmation. It can be provided as possible. For example, the linked service provider 255 may search for rental services such as air purifiers and dehumidifiers according to the user's life characteristics and provide them to the user.

In this way, the controller 250 learns sensor data of the interior and exterior environment of the door acquired by the sensor unit 230 and automatic door control information of the user, and provides a user-customized automatic door opening and closing service according to the interior and exterior environment of the door. I can.

The display unit 270 is for outputting an audio signal, a video signal, or an alarm signal, and may be implemented as a display panel.

For example, the display unit 270 is a GUI so that sensor data of environmental information acquired from the sensor unit 230, various related service information, operation status, access record, security check, self check, failure notification, etc. You can create and print (graphical user interface).

The driving unit 290 is driven under the control of the controller 250 to enable automatic opening and closing of the door. Alternatively, the driving unit 290 is driven according to a user's manipulation to enable automatic opening and closing of the door. Alternatively, the driving unit 290 is driven according to a signal remotely received from the user terminal 100 to enable automatic opening and closing of the door.

To this end, the driving unit 290 may be implemented by including a piezoresistive operation button and a linear motor.

3 is an example of a linear motor included in the driving unit illustrated in FIG. 2.

The drive unit 290 includes a linear motor as shown in FIG. 3 to enable automatic opening and closing of the door in a sliding manner.

Linear motor is a linear movement module in which the central axis of the motor moves directly through a screw, and is widely applied to sliding automatic doors because it can supply linear reciprocating power. Linear motors can be divided into two types: the motor moves directly from the screw and the screw turns. Compared to the gear method, the linear motor is quieter and smoother, and the parts can be simplified to prevent failure of the automatic door. It can also be applied to existing window frames.

The piezoresistive operation button may be provided on one side of the door frame. The piezoresistive operation button is interlocked with the linear motor, and when pressure is applied to the piezoresistive operation button, the linear motor can be operated. The user can open or close the door by pressing the piezoresistive operation button. For example, the piezoresistive operation button may be provided in the form of a footrest at the bottom of the door frame. The user can open and close the door by operating the footrest.

In the present embodiment, the piezoresistive operation button may control the driving speed of the linear motor by subdividing the pressing pressure. That is, the user can adjust the opening and closing speed of the door by adjusting the intensity of pressing the piezoresistive operation button. For example, when the user touches the piezoresistive operation button, the door can be completely opened or closed at a normal speed. Alternatively, when the user opens the door to an arbitrary size, the opening and closing size can be easily adjusted by using a piezoresistive operation button.

In addition, in the present embodiment, a piezoresistance may be embedded in the rail guiding the sliding movement of the door. The piezoresistive built-in rail can detect contact, and when the contact is detected, the opening and closing operation of the door is automatically stopped, thereby preventing injury.

Meanwhile, although not shown in FIG. 2, the IoT-based switching device 200 may further include a power supply unit. The power supply unit may receive external power and supply power required for the operation of the IoT-based switchgear 200. In addition, the power supply unit may supply power necessary for the operation of the IoT-based switchgear 200 even when external power cannot be supplied due to the battery. Accordingly, in an emergency situation such as a natural disaster, the user's safety can be secured through automatic door control.

As such, the IoT-based opening and closing device 200 according to an embodiment of the present invention is applied to a door capable of automatically opening and closing, and provides a door automatic opening/closing service according to internal and external environment information of the door or a user's door opening pattern. Can provide.

Accordingly, the user can not only open and close the door without difficulty, but also provide a comfortable living environment by providing adequate ventilation and the like according to the surrounding environment information. In addition, it is possible to improve the user's convenience in life by allowing automatic opening and closing without a separate operation according to the user's life pattern.

Hereinafter, an IoT-based opening and closing method according to an embodiment of the present invention will be described with reference to FIG. 4.

4 is a flowchart of an IoT-based opening and closing method according to an embodiment of the present invention.

The IoT-based opening and closing method according to an embodiment of the present invention may be performed in substantially the same configuration as the IoT-based opening and closing device 200 shown in FIGS. 1 and 2. Accordingly, the same components as those of the IoT-based opening and closing device 200 of FIGS. 1 and 2 are given the same reference numerals, and repeated descriptions are omitted.

Referring to FIG. 4, the sensor unit 230 may collect sensor information (S500 ).

The sensor unit 230 may collect sensor information by sensing internal and external environment information of the door. The sensor unit 230 may include a rain detection sensor, a fine dust sensor, a temperature sensor, and a radon detection sensor to collect sensor data about internal and external environment information of the door.

The controller 250 may analyze the sensor information (S510).

The control unit 250 may learn a user's door opening/closing preference condition according to sensor information of an internal/external environment of the door acquired by the sensor unit 230. When the door is opened or closed, the controller 250 may learn a user's door opening/closing preference condition by matching sensor data acquired by the sensor unit 230 at a corresponding time point.

The controller 250 may control the opening or closing of the door according to the sensor information (S520).

When the sensor information satisfies the user's preference for opening and closing the door, the controller 250 may automatically control the opening or closing of the door. Alternatively, the controller 250 may automatically control the opening or closing of the door only when it transmits a door open/close permission request signal to the user terminal 100 and receives a door open/close permission signal in response thereto. Alternatively, the control unit 250 may provide only information notifying the user terminal 100 that the user's door opening/closing preference condition is met to the current interior/exterior environment of the door.

In addition, the controller 250 may set a door open/close condition in advance, and automatically control opening or closing of the door when sensor data collected by the sensor unit 230 satisfies the door open/close condition. Here, the door open/close condition may be set by a user. Alternatively, the door opening/closing condition may be set in advance as a rainy weather situation, fine dust level, temperature, radon level, etc. that generally require the door to be opened or closed.

The controller 250 may provide a linked service according to the sensor information (S530).

The controller 250 may provide an additional service according to sensor information of the interior and exterior environment of the door acquired by the sensor unit 230. The controller 250 may obtain environmental characteristics of a corresponding region by analyzing sensor data of the interior and exterior environment of the door acquired by the sensor unit 230 for a predetermined period. The controller 250 may search for and provide additional services according to environmental characteristics. Alternatively, the control unit 250 may check the life characteristics of the user according to the user's preference for opening and closing the door. The control unit 250 may search for an additional service according to the user's life characteristics, transmit it to the user terminal 100, or output it to the display unit 270, which will be described later, so that the user can check it.

Although the above has been described with reference to embodiments, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention described in the following claims. I will be able to.
