[0247] The upper part (250) can be maintained in position above the lower part (210) by a bushing (290). The upper part (250) is positioned so as to be able to move upward and downward above the lower part (210). The bushing (290) can limit the upward movement of the upper part (250).

[0248] In a state where the upper part (250) is placed on the upper side of the lower part (210), the bushing (290) can be mounted on the protrusion (242) formed on the lower part (210). When the bushing (290) is mounted on the protrusion (242), the middle plate (280) of the upper part (250) can be placed in contact with the weight sensor (244) of the lower part (210).

[0249] The middle plate (280) is fixedly placed on the inner side of the seat cover (266).

[0250] When the upper part (250) is placed on the upper side of the lower part (210), the pressurizing part (284) of the middle plate (280) can be placed in contact with the upper side of the weight sensor (244).

[0251] The upper part (250) is positioned above the lower part (210). The positioning of the upper part (250) can be maintained by the middle plate (280), the protrusion (242), and the bushing (290). The upper part (250) is positioned so as to be able to move up and down on the upper side of the lower part (210).

[0252] The middle plate (280) is positioned apart from the printed circuit board (246). Therefore, even when the upper part (250) moves up and down, the middle plate (280) does not come into contact with the printed circuit board (246).

[0253] The pressurizing portion (284) of the middle plate (280) is arranged to be in contact with the weight sensor (244). When a pet is placed on the upper side of the upper part (250), at least one of the plurality of pressurizing portions (284) can press the corresponding weight sensor (244). Accordingly, the weight of the pet placed on the upper side of the upper part (250) can be measured.

[0254] When force is applied to one side of the upper part (250), the upper part (250) in the area where the force is applied can move downward. At this time, the middle plate (280) arranged on one side also moves downward.

[0255] The air purifier (1) can perform air purification operation even when a pet is positioned on the seat device (200) by positioning the seat device (200) on the upper side of the main body (100).

[0256] Furthermore, by placing the resting area in a high space, we increased the possibility of pets entering the resting area. In particular, reflecting the characteristic of cats who like to climb to high places, we incorporated a space for cats to rest on top of the air purifier (1).

[0257] The height of the seat device (200) is similar to that of a bed, providing a resting space at eye level with the cat owner. This has the effect of enhancing the happiness and comfort of the pet.

[0258] According to the present disclosure, there is an advantage in that a single product simultaneously provides a resting space for pets and air purification functions, thereby eliminating the need for additional products.

[0259] In addition, reflecting the characteristics of cats that like to wrap themselves around the body and prefer warm spaces, the air purifier (1) provides a heating function using a heater (264).

[0260] Additionally, functions such as measuring a cat's weight and usage time are applied to the space, allowing the cat's daily life patterns to be naturally measured, and cat owners can utilize this information to manage their cat's health. The measured data can be checked and managed through the application.

[0261] The air purifier (1) features various functions, such as pet weight measurement, heating function, and usage time measurement, and can analyze the pet's condition and lifestyle patterns. Users can run the application on their mobile devices to check real-time weight measurement results, weight measurement history, and other information, and control the heating temperature.

[0262] In households with multiple pets, it's important to identify and manage them. The air purifier (1) can identify pets using a Radio Frequency Identification System (RFID).

[0263] RFID is a technology that uses radio frequencies to identify objects. It stores information in RF tags, which consist of an antenna and a chip. These tags are then attached to the target and read by an RFID reader. RFID tags are categorized as active and passive, depending on whether they contain a built-in battery.

[0264] FIG. 10 is a drawing for reference in the description of an RFID tag according to one embodiment of the present disclosure.

[0265] Referring to FIG. 10, an RFID tag (1000) may be provided on a collar worn by a pet, such as a cat. Alternatively, an RFID tag (1000) may be provided on clothing or a harness worn by the pet. Alternatively, the RFID tag (1000) may be attached to the pet in various forms.

[0266] An RFID tag (1000) communicates with an RFID reader (not shown) and wirelessly transmits data to the RFID reader. The RFID reader (not shown) may be provided in a control unit (1340, see FIG. 12) or a communication unit (1370, see FIG. 12) described below. For signal transmission and reception, the RFID reader may include an RFID antenna (1300, see FIG. 13).

[0267] Referring to Fig. 10, each cat is fitted with a necklace-type RFID tag (1000) around its neck.

[0268] The air purifier (1) can recognize an RFID tag (1000) and check identification (ID) information corresponding to the RFID tag (1000).

[0269] In addition, the air purifier (1) can manage data by identification information and provide customized services.

[0270] FIG. 11a and FIG. 11b are drawings for reference in a description of a pet management function using a mobile terminal according to an embodiment of the present disclosure, and illustrate user interface screens of an application executed on the mobile terminal.

[0271] A user can check and control the status of the air purifier (1) by running an application (e.g., ThinQ) or accessing a specific website via a mobile terminal. In addition, the user can control the weight measurement function, heating function, etc. of the air purifier (1) via the mobile terminal.

[0272] For example, users can set the operating mode and target temperature of the heating function via their mobile device. Furthermore, users can measure their pet's weight and check the most recent weight measurement data and existing data via their mobile device.

[0273] Additionally, data can be stored and managed for each pet according to identification information recognized using an RFID tag (1000).

[0274] Referring to FIG. 11a, when an air purifier-related application is executed on a mobile terminal, a user interface (UI) screen (1110) is exemplified.

[0275] The UI screen (1110) may include pet items (1111, 1112) registered by the user. For example, the user may register his or her own pet cats.

[0276] The pet items (1111, 1112) may include a photo and / or icon of the pet. Additionally, the pet items (1111, 1112) may include user-registered information such as the pet's name and age.

[0277] Additionally, the UI screen (1110) may include items related to the pet's weight measurement function and items related to the heating function. Items related to the heating function may include items for setting the operating mode of the heating function and items for setting the target temperature of the heating function.

[0278] For example, an item that can set the target temperature of the heating function can be provided so that heating level 1 or heating level 2 can be selected, or so that the target temperature can be selected directly.

[0279] For example, the operating mode of the heating function may include a constant mode and a recognition mode.

[0280] The constant mode is a mode that provides the heating function according to the set target temperature when the heating function is turned on through a switch (248a, 248b, 248c) or an application.

[0281] The recognition mode is a mode that provides a heating function only when a pet is detected by the weight sensor (244), and provides a heating function from the moment the pet gets on the seat device (200).

[0282] Meanwhile, the user can select one of the pet items (1111, 1112). The selected pet item (1111) can be displayed separately from the remaining pet items (1112).

[0283] Meanwhile, when a user executes the weight measurement function while a pet item (1111) is selected or calls up the detailed menu of the pet item (1111), additional information / functions related to the pet item (1111) can be provided.

[0284] Referring to Figure 11b, the detailed screen for the selected pet item (1111) includes information on the average weight and weight trend of the corresponding pet over a given period. Additionally, menu items allowing users to view additional information, such as "View All Data," are provided.

[0285] The air purifier (1) can automatically identify and measure the weight of multiple cats or other pets. The weights of the identified cats can be recorded and provided to the user through an application.

[0286] The air purifier (1) can identify a pet on a seat device (200) using RFID and transmit measured data along with the identification information of the identified pet to a server via a communication unit (1330, see FIG. 12). The server can store and manage the received information and provide pet-related services through applications, websites, etc.

[0287] According to an embodiment, the air purifier (1) can communicate directly with a mobile terminal. For example, the communication unit (1330) can transmit measured data along with identification information of the identified pet to the mobile terminal.

[0288] The air purifier (1) can identify a pet on the seat device (200) using RFID, map measured data to the identification information of the identified pet, and store it in the memory (1330, see FIG. 12).

[0289] FIG. 12 is a block diagram of an air purifier according to an embodiment of the present disclosure.

[0290] Referring to FIG. 12, an air purifier according to an embodiment of the present disclosure may include a control unit (1340) and a fan driving unit (1380) that drives a fan (140) according to the control of the control unit (1340).

[0291] At least some of the internal blocks of the air purifier illustrated in FIG. 12, such as the control unit (1340) and the fan drive unit (1380), may be placed inside the main body (100). For example, the control unit (1340) may be mounted on a printed circuit board (123) placed in a space formed by the lower housing (114) placed on the upper side of the base (110).

[0292] A fan (140) is installed inside the main body (100) to control the flow of indoor air that is purified while passing through a filter (101) and then discharged into the indoor space. The fan (140) can be rotatably arranged between the inlet (106) and the outlet (112) to form an air flow from the inlet (106) to the outlet (112).

[0293] The fan motor (148) rotates the fan (140) according to a control signal received from the fan driving unit (1380). The rotation of the fan (140) is controlled by the fan driving unit (1380), and the operation of the fan driving unit (1380) is controlled by the control unit (1340). The fan driving unit (1380) may be equipped with a power conversion device such as an inverter to operate the fan motor (148).

[0294] The filter (101) removes foreign substances in the air flowing into the inlet (106). The filter (101) may include a pre-filter that filters foreign substances in the air, a HEPA filter that collects pollutants in the air, a deodorizing filter that removes odors in the air, etc. The pre-filter has a grill formed to primarily filter foreign substances in the air being sucked in. The HEPA filter collects pollutants in the sucked in air, and the deodorizing filter can remove odors in the sucked in air.

[0295] Meanwhile, the air purifier may include a memory (1330), a sensing unit (1350), a communication unit (1370), etc.

[0296] The memory (1330) may store data for controlling the operation of the air purifier, data detected or measured through the sensing unit (1350) during operation, and data received through the communication unit (1370). Meanwhile, the air purifier may include a buffer for temporarily storing data, and the buffer may be included in the control unit (1340) or the memory (1330).

[0297] The control unit (1340) can process various data received through the communication unit (1370) to update the memory (1145). For example, if the data input through the communication unit (1370) is update data for a driving program pre-stored in the memory (1330), the memory (1330) can be updated using this, and if the input data is a new driving program, the memory (1330) can be additionally stored therein.

[0298] The sensing unit (1350) can measure the level of air pollution or sense the operating status of the air purifier by including one or more sensors.

[0299] The control unit (1340) can control the flow of data input or output to the air purifier and generate and apply a control command based on data input from the sensing unit (1350).

[0300] Meanwhile, the air purifier can communicate with other devices such as servers, home appliances, and terminals through the communication unit (1370) to transmit and receive data.

[0301] The input unit (1310) can receive various user commands related to the operation of the air purifier and transmit a control signal corresponding to the input command to the control unit (1340). The input unit (1310) can include a touch pad, physical buttons, etc.

[0302] The output unit (1320) may be equipped with a display device such as a display (not shown) or a light emitting diode (LED) (not shown). For example, the output unit (1320) may display information such as the operating status of the air purifier, the occurrence of an error, the indoor temperature, and the target temperature.

[0303] The output unit (1320) may be equipped with an audio device such as a speaker (not shown) or a buzzer (not shown). For example, the output unit (1320) may output a sound effect regarding the operating status of the air purifier and may output a predetermined warning sound when an error occurs.

[0304] The control unit (1340) may be connected to each component of the air purifier. For example, the control unit (1340) may transmit and / or receive signals between each component of the air purifier and control the overall operation of each component.

[0305] The control unit (1340) may include at least one processor, and may control the overall operation of the air purifier using the processor included therein. Here, the processor may be a general processor, such as a central processing unit (CPU). Of course, the processor may also be a dedicated device, such as an ASIC, or another hardware-based processor.

[0306] Meanwhile, the control unit (1340) can control the overall operation of the air purifier and control a series of air purification processes such as intake of outside air and discharge of purified air.

[0307] The control unit (1340) can perform an air purification process according to a preset algorithm, and the fan drive unit (1380) can drive the fan (140) according to the control of the control unit (1340). The fan motor (148) is operated by a control signal sent from the fan drive unit (1380). The fan drive unit (1380) can control the rotation speed and direction of the fan (140) based on the control signal generated to improve air characteristics.

[0308] When the fan driver (1380) drives the fan (140) by rotating the fan motor (148), external air can be sucked into the air purifier through the inlet (106). The sucked air can be purified while passing through the filter (101) and then discharged to the outside through the outlet (112).

[0309] Meanwhile, the air purifier may be equipped with a temperature control function for pets. For example, a heater (264) is provided within the seat device (200). The control unit (1340) can operate the heater (264) to provide a heating function for pets positioned on the seat device (200).

[0310] The control unit (1340) can receive sensing data of the weight sensor (244) from the printed circuit board (246) of the seat device (200) and determine whether the pet is in the seat device (200). The control unit (1340) can control the fan (140) and the heater (264) based on whether the pet is in the seat device (200).

[0311] Additionally, one or more temperature sensors (not shown) may be placed in the sheet device (200), and the printed circuit board (246) may transmit sensing data of the temperature sensor to the control unit (1340).

[0312] According to an embodiment, the seat device (200) may include a separate seat control unit. The seat control unit may be mounted on a printed circuit board (246). The seat control unit may control the heater (264) of the seat device (200). The seat control unit may communicate with the control unit (1340) and operate the heater (264) based on a signal received from the control unit (1340).

[0313] The seat control unit can transmit data from the sensors to the control unit (1340). In addition, the seat control unit can receive sensing data from the weight sensor (244) and determine whether the pet is in the seat device (200). The seat control unit can receive sensing data from the temperature sensor and determine the temperature of the seat device (200) and / or the pet.

[0314] The seat device (200) includes a weight sensor (244) that detects the presence of a pet. For example, the control unit (1340) recognizes, through the weight sensor (244), whether a pet cat is present in the cat resting area of ​​the seat device (200).

[0315] The weight sensor (244) can be placed on the upper side of the lower body (211). The weight sensor (244) can detect the weight on the upper side of the upper part (250).

[0316] For example, the weight sensor (244) may be a load cell (244). Hereinafter, a case in which a load cell (244) is used will be described as an example.

[0317] The load cell (244) can detect whether a cat is on the seat device (200). In addition, the load cell (244) can measure the weight of the cat on the seat device (200).

[0318] The load cell (244) can measure the time the cat climbs onto the seat device (200) and the time the cat climbs off the seat device (200). In addition, the control unit (1340) can measure the resting pattern of the pet using the load cell (244).

[0319] The air purifier (1) measures the point at which the cat goes up and down through the load cell (244), and can control the temperature and air volume of the heater (264) according to the logic.

[0320] The air purifier (1) includes an RFID reader, and the RFID reader can recognize an RFID tag (1000) and receive data.

[0321] An RFID reader may be included in the control unit (1340).

[0322] Alternatively, the RFID reader may be included in the communication unit (1370) or may be provided independently. In this case, the RFID reader may transmit information about the recognized RFID tag to the control unit (1340).

[0323] Meanwhile, the air purifier (1) includes an RFID antenna (1300). The RFID antenna (1300) may be composed of an RFID reader and an RFID module, or may be independently installed in the air purifier (1).

[0324] The RFID antenna (1300) can output signals from the RFID reader to the outside in the form of radio waves. The RFID tag (1000) can receive energy through the signals.

[0325] Additionally, the RFID antenna (1300) can receive a signal from the FID tag (1000) and transmit the received signal to the RFID reader.

[0326] An RFID reader can recognize an RFID tag (1000) by receiving a signal containing unique identification information transmitted from the RFID tag (1000).

[0327] An RFID tag (1000) can be mapped to each pet. In some cases, the RFID tag (1000) may include the type of pet and other information in addition to identification information.

[0328] The air purifier (1) can be used to manage data and provide customized services by using the information of the recognized RFID tag (1000).

[0329] Meanwhile, even when a pet such as a cat does not climb onto the seat device (200), the RFID tag (1000) may be recognized if the pet is around the air purifier (1). In this case, the pet is not resting on the seat device (200) and is not using any pet-related functions, so it is considered an RFID misrecognition.

[0330] The present disclosure proposes a structure and control method that can prevent such RFID misrecognition and improve the accuracy of RFID recognition.

[0331] FIG. 13 is a cross-sectional view of one side of a sheet device according to an embodiment of the present disclosure, and FIG. 14 is a drawing illustrating an RFID antenna arranged in the sheet device of FIG. 13.

[0332] Referring to FIGS. 13 and 14, the seat device (200) includes a seat (254) and a seat cover (266) surrounding the outer periphery of the seat (254).

[0333] The seat cover (266) forms a space (267) above the seat (254) where a pet such as a cat can rest. The RFID antenna (1300) is formed in a circular shape. The RFID antenna (1300) is arranged to surround the space (267).

[0334] By using a circular RFID antenna (1300), the influence of the direction in which the pet enters the space (267) and the pet's location within the space (267) can be minimized. For example, even if a cat falls behind the seat cover (266) and is located only on one side of the seat (254), the RFID antenna (1300) can receive a signal from the RFID tag (1000).

[0335] When a pet wearing an RFID tag (1000) enters the space (267), the RFID antenna (1300) receives a signal from the RFID tag (1000), and the air purifier (1) can identify the pet located in the space (267).

[0336] The seat cover (266) may be partially opened so that the pet can enter and exit the space (267). The seat cover (266) may be opened on the upper side and one side of the front, and may form a space (267) on the inside.

[0337] The RFID antenna (1300) may be placed on the top of the seat cover (266). The RFID antenna (1300) may be placed on the LL line connecting the top of the seat cover (266). The RFID antenna (1300) may receive a signal from the RFID tag (1000) of the pet that has passed through the LL line. The opening of the seat cover (266) may be an entrance to a space (267). When the upper surface of the opening of the seat cover (266) is viewed from the side, it becomes the LL line. The RFID antenna (1300) may be placed to surround the entrance to the space (267).

[0338] The seat cover (266) may include an inner cover (276) arranged to face the space (267) and an outer cover (268) arranged around the outer perimeter of the inner cover (276).

[0339] A space (267) is formed on the upper side of the sheet (254). A mounting plate (258) is arranged on the lower side of the sheet (254). A mounting portion (270) protruding in the direction in which the mounting plate (258) is arranged is arranged on the outer cover (268). The mounting portion (270) can form a surface parallel to the mounting plate (258).

[0340] The inner cover (276) can be mounted on the inner side of the outer cover (268). The RFID antenna (1300) is mounted in a ring shape between the inner cover (276) and the outer cover (268), so as to identify a pet entering the inside of the seat cover (266).

[0341] A separation space (278) may be formed between the inner cover (276) and the outer cover (268). The inner cover (276) contacts the outer cover (268) at each of the upper portion (276a) and the lower portion (276b), and a separation space (278) may be formed between the inner cover (276) and the outer cover (268) in the area between the upper portion (276a) and the lower portion (276b).

[0342] The RFID antenna (1300) can be placed inside the isolation space (278). If the RFID antenna (1300) is in the isolation space (278), it is not exposed to the outside and can be prevented from being damaged by pets.

[0343] The RFID antenna (1300) may be positioned at the upper portion of the separation space (278). By positioning the RFID antenna (1300) at the upper portion of the separation space (278), a signal can be received from the RFID tag (1000) of the companion animal that has passed through the LL line. More preferably, the RFID antenna (1300) may be positioned at the uppermost portion of the separation space (278).

[0344] Meanwhile, the RFID antenna (1300) can come into contact with the inner cover (276) and the outer cover (268). The RFID antenna (1300) can be stably fixed at a position where it comes into contact with both the inner cover (276) and the outer cover (268).

[0345] The outer cover (268) may include a first outer cover (268a) extending upwardly from the mounting plate (258) and a second outer cover (268b) extending downwardly from the first outer cover (268a).

[0346] The first outer cover (268a) may have a structure extending upward from the second outer cover (268b). The first outer cover (268a) may form a space (267) in which a companion animal is positioned above the mounting plate (258).

[0347] The first outer cover (268a) may have a structure in which the height varies depending on the circumference. The upper end of the first outer cover (268a) may have a structure in which the height increases from the first point (269a) to the second point (269b).

[0348] The RFID antenna (1300) may be positioned along the perimeter of the first outer cover (268a). Depending on the shape of the first outer cover (268a) with varying heights, the RFID antenna (1300) may be positioned at an angle when viewed from the side.

[0349] According to an embodiment, an RFID reader circuit may be mounted on a printed circuit board (246) on the lower side of the sheet (254). Alternatively, the RFID reader circuit may be mounted on a printed circuit board (123) inside the main body (100). Alternatively, an RFID reader may be provided separately and placed inside the sheet device (200) or the main body (100).

[0350] The air purifier (1) provides a resting space (267) for pets and can measure and manage the weight of pets located in the resting space (267). Weight measurement data can be managed for each identified pet.

[0351] Additionally, the air purifier (1) can provide a heating function to a pet located in a resting area (267). At this time, an optimized temperature setting for each identified pet can be applied to the heating function.

[0352] In addition, the air purifier (1) can minimize the stress that the pet receives from the movement of the main body (100) by adjusting the air volume in response to the pet located in the resting area (267).

[0353] Meanwhile, even when the pet is not on the seat (254), the information of the RFID tag (1000) can be recognized if it is located within the recognition range of the RFID antenna (1300). In this case, the air purifier (1) can perform unnecessary customized service operations.

[0354] In order to prevent RFID misrecognition, the information of the weight sensor (244) described above can be additionally utilized.

[0355] When an RFID tag (1000) is recognized by the RFID antenna (1300), the control unit (1340) checks the data of the weight sensor (244). Based on the data of the weight sensor (244), when a pet on the sheet (254) is detected, the communication unit (1370) can transmit identification information corresponding to the RFID tag (1000) to the server.

[0356] Accordingly, the air purifier (1) and server can provide customized services to the identified pet.

[0357] When the heating function is used, if an RFID tag (1000) is recognized by the RFID antenna (1300), the heater (264) can operate based on the temperature set in the identification information corresponding to the RFID tag (1000).

[0358] Additionally, the memory (1330) can store the operating time information of the heater (264) by mapping it to identification information corresponding to the RFID tag (1000).

[0359] Additionally, the communication unit (1370) can transmit the operating time information of the heater (264) to the server together with the RFID tag (1000).

[0360] In addition, when an RFID tag (1000) is recognized by the RFID antenna (1300) and a pet on the sheet (254) is detected based on data from the weight sensor (244), the communication unit (1370) can transmit weight information measured by the weight sensor (244) to the server. In this case, the communication unit (1370) can transmit identification information corresponding to the RFID tag (1000) together with the weight information. The server can store and manage the measured weight information by mapping it to identification information corresponding to the RFID tag (1000).

[0361] When an RFID tag (1000) is recognized by the RFID antenna (1300), the control unit (1340) checks the data of the weight sensor (244). Based on the data of the weight sensor (244), when a pet on the sheet (254) is detected, the memory (1330) can store identification information corresponding to the RFID tag (1000).

[0362] The memory (1330) can store and manage measured weight information by mapping it to identification information corresponding to an RFID tag (1000).

[0363] FIG. 15 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure. FIG. 16 and FIG. 17 are drawings referenced in a description of RFID recognition of an air purifier according to an embodiment of the present disclosure.

[0364] First, referring to FIG. 15, an RFID tag (1000) can be registered in an application (S1510). For example, after a user launches the application on a mobile terminal, the user can select an RFID tag (1000) and enter information about a pet wearing the RFID tag (1000).

[0365] When the RFID tag (1000) is registered, the registered pet items are displayed on the UI screen of the application (App).

[0366] If there are multiple RFID tags (1000), the user can register other pets in the same manner.

[0367] Figure 11a illustrates a user interface (UI) screen (1110) when two cats are registered. A user can select a registered pet item (1111, 1112) to check detailed information about the pet and set up customized services.

[0368] Referring to Fig. 16, when a cat (1600) wearing an RFID tag (1000) climbs onto the seat device (200), the signal of the RFID tag (1000) can be received by the RFID antenna (1300) (S1520).

[0369] According to an embodiment, it is possible to additionally check whether the signal received from the RFID antenna (1300) is an RFID signal (S1530). In addition, it is possible to additionally check whether the signal received from the RFID antenna (1300) is an RFID signal that can be processed by the air purifier (1) (S1530).

[0370] Referring to Fig. 17, even if the cat (1800) is not on the seat device (200), if the cat (1800) wearing the RFID tag (1000) comes near the RFID antenna (1300), the RFID tag may be incorrectly recognized. For example, if the cat (1800) moves on an object (1700) around the air purifier, such as a desk, chair, or sofa, the RFID tag (1000) may be unintentionally recognized without the cat (1800) coming up onto the seat device (200).

[0371] In order to determine whether the pet has climbed onto the seat device (200) or is only around the seat device (200), the control unit (1340) can check the load cell (244) signal (S1540).

[0372] When the RFID antenna (1300) receives a signal from the RFID tag (1000) (S1520), the control unit (1340) can check the signal from the load cell (244) (S1540). If the weight is detected from the load cell (244) and a signal is generated (S1540), the control unit (1340) can determine that the pet has climbed onto the seat device (200).

[0373] The control unit (1340) can accurately measure the weight of a pet that has climbed onto the seat device (200) through the load cell (244) (S1550).

[0374] The control unit (1340) can check identification information such as an ID corresponding to the RFID tag (1000) (S1560).

[0375] To prevent misrecognition, when the value of the load cell (244) and the RFID signal are input together, the control unit (1340) processes the received RFID signal and confirms the identification information of the corresponding RFID tag (1000) (S1560).

[0376] Thereafter, the control unit (1340) can provide customized services to the identified pet. In addition, the control unit (1340) can manage data by identification information.

[0377] For example, the communication unit (1370) may transmit a body weight measurement value to a connected application or server (S1570). In this case, the communication unit (1370) may also transmit identification information, and the body weight measurement value may be mapped to an identified pet for management.

[0378] The combination and order of each of the steps illustrated may vary. For example, after the control unit (1340) verifies the identification information corresponding to the RFID tag (1000) (S1560), the weight of the pet that has climbed onto the seat device (200) can be measured through the load cell (244) (S1550).

[0379] Alternatively, when the RFID antenna (1300) receives a signal from the RFID tag (1000) (S1520), the control unit (1340) may determine the weight of the pet based on the confirmed load cell (244) signal (S1540). In this case, the step (S1550) of measuring the weight by checking the load cell (244) value again will be omitted.
