Referring to FIG. 1, the air purifier integrated management system according to the present embodiment includes a management server 1 and a plurality of air purifiers 2. In this embodiment, one management server and six air cleaners are shown. However, the number of the management servers and the air cleaners may vary depending on the size and structure of the space where the management server and the air cleaner are installed. Both the management server and the plurality of air cleaners include an access point (AP) module and can act as an access point. The access point can establish a wireless link with another access point within the coverage area of the access point. That is, a wireless link can be established between the management server, the air purifier, and the air purifier.

The second air cleaner 22 establishes a wireless link with the fourth air cleaner 24 located in the communicable area of the second air cleaner 22 and the third air cleaner 23 establishes a wireless link with the third air cleaner 23. [ And the fifth air cleaner 25 located in the communicable area of the second air cleaner 23.

Thereby, the wireless link between the management server 1 and the first air cleaner 21, the wireless link between the first air cleaner 21 and the second air cleaner 22, and the wireless link between the second air cleaner 22 and the fourth The wireless link between the air cleaner 24 and the air cleaner 24 is cascade connected and the wireless link between the management server 1 and the third air cleaner 23 and the wireless link between the third air cleaner 23 and the fifth air cleaner 25 A wireless chain network is formed in which links are cascade-connected.

As shown in FIG. The management server 1 comprises an AP module 11, a data processing module 12, a control module 13, and a storage 14. The AP module 11 of the management server 1 establishes a wireless link with the AP module 211 of the air cleaner 21. [ The AP module 11 assigns an IP address to the first air cleaner 21 that establishes a wireless link with the management server 1. [ The management server 1 receives dust concentration data or status data from the first air cleaner 21 via a wireless link or transmits operation schedule data to the first air cleaner 21. [ In addition, the AP module 11 can receive dust concentration data from other servers such as a school office server, a weather station server, etc. through a network such as the Internet and receive usage schedule data from a computing device such as a user's smart phone, . For example, the AP module 11 of the management server 1 can wirelessly communicate with the first AP module 211 of the first air cleaner 21 through a wireless communication network such as Wi-Fi . The AP module 11 of the first air cleaner 2 inputs the data received from the management server 1 to the data processing module 12.

The data processing module 12 stores the extracted IP address in the storage 14 and inputs the extracted dust concentration data to the server control module 13. [ The data processing module 12 receives operation schedule data including the operation strength and operation time of each air cleaner inputted from the control module 13 and the IP address of each air cleaner inputted from the storage 14 . The data processing module 12 inputs the generated operation schedule data to the wireless communication module 11, and the wireless communication module 11 transmits the operation schedule data to each air cleaner.

The control module 13 of the management server 1 determines the operation time and the operation strength of each air cleaner based on the dust concentration data inputted from the data processing module 12. [ The control module 13 controls the operation of the air cleaner based on the dust concentration measured by the dust sensor of each air cleaner from the plurality of air cleaners 21, 22, 23, 24, 25 connected to the management server 1 and the wireless link and wireless chain network The operating strength and operating time of each air cleaner are determined. Then, the control module 13 inputs the operation intensity and operation time for each determined air cleaner to the data processing module 12. [

For example, when there is a large amount of dust in the space where the first air cleaner 21 is installed and less dust is present in the space where the second air cleaner 22 is installed, the dust sensor 216 of the first air cleaner 21 The measured dust concentration data indicates a high dust concentration and the dust concentration data measured by the dust sensor 216 of the second air cleaner 22 indicates a low dust concentration. In this case, the management server 1 receives the dust concentration data from each of the first air cleaner 21 and the second air cleaner 22, and based on this data, the first air cleaner 21 and the second air cleaner 22 ) And the operating time and the operating time of each of them. The management server 21 allows the first air cleaner 21 to operate for a longer period of time than the second air cleaner with a higher operating intensity and the second air cleaner 22 can operate the first air cleaner 21 with a lower operating intensity, To operate for a short period of time.

In addition, the management server 1 can receive data on the fine dust concentration in the area where a plurality of air cleaners are installed, from the meteorological office server via the Internet. The management server 1 can control the operation of a plurality of air cleaners based on the received fine dust concentration data. For example, if the concentration of fine dust in a region where a plurality of air cleaners are installed is high, all the air cleaners can be controlled to operate with high operating intensity and for a long operating time.

The storage 14 of the management server 1 stores the IP address assigned to the air cleaner connected to the management server 1. [ The storage 14 is connected to the management server 1 and the air cleaners 22, 24 and 25 when the air cleaners 22, 24 and 25 are connected to the management server 1 through the other air cleaners 21 and 23.

The first AP module 211 establishes a wireless link with the AP module 11 of the management server 1 and receives the operation schedule data from the management server 1 or transmits the dust concentration data or status data to the management server 1 send. In another embodiment, the first AP module 211 of the first air cleaner 21 can establish a wireless link with the AP module of another air purifier.

The second AP module 212 of the first air cleaner 21 establishes a wireless link with the first AP module 221 of the second air cleaner 22 and sets the operation schedule data transmitted from the air cleaner 1 2 air cleaner 22 and receives the dust concentration data or the status data transmitted from the second air cleaner 22. [ The second AP module 212 assigns an IP address to the second air cleaner 22. As such, the air purifier according to the present embodiment includes two AP modules, so that an IP address can be assigned from the management server 1 (or an air purifier connected to the management server) to establish a wireless link, You can assign an address to establish a wireless link.

When the extracted IP address matches the IP address of the first air cleaner 21, the data processing module 212 inputs the extracted operation schedule data to the control module 214. When the extracted IP address is the first air And inputs the data transmitted from the management server 1 to the second AP module 212 when it does not match the IP address of the purifier 21. The second AP module 212 transmits the input data to the second air cleaner 22 again. That is, when the destination of the data transmitted from the management server 1 is not the first air cleaner 21 but the second air cleaner 22, the first air cleaner 21 transmits the data transmitted from the management server 1 And transmits it to the second air cleaner 22 again.

The control module 214 of the first air cleaner 21 operates the first air cleaner by controlling the filter 13 and the suction fan 215 according to the operation intensity and the operation time included in the inputted operation schedule data.

The integrated management method of the air purifier according to the present embodiment includes the following steps performed between the management server 1, the first air cleaner 21 and the second air cleaner 22 shown in FIG. 1 .

In step 301, the first air cleaner 21 searches the management server 1 or another air cleaner located in the communicable area of the first air cleaner 21 and serving as an access point. For example, the first air cleaner 21 may include a management server 1 serving as an access point in such a manner as to broadcast a DHCP discover message including a Media Access Control (MAC) address of the first air cleaner, Or an air purifier.

In step 302, when the management server 1 is located within the communicable area of the first air cleaner 21, the management server 1 sends a DHCP offer message to the first air cleaner 21. In response to the DHCP discovery message of the first air cleaner 21, the management server 1 transmits a DHCP provision message to the first air purifier 21. For example, the DHCP providing message includes data such as a MAC address of the first air cleaner 21, an IP address to be assigned to the first air cleaner 21 by the management server 1, and the like.

In step 303, the first air cleaner 21 transmits an IP address allocation request message to the management server 1. [ For example, the first air cleaner 21 transmits a DHCP request message to the management server 1. The DHCP request message includes data such as a MAC address of the first air cleaner 21, an IP address that the management server 1 is to assign to the first air cleaner 21, and the like.

In step 304, the management server 1 assigns an IP address to the first air cleaner 21 that has transmitted the IP address allocation request message. When receiving the IP address allocation request message (DHCP request message) from the first air cleaner 21, the management server 1 responds to the IP address allocation request message transmitted from the first air cleaner 21, And transmits an IP address assignment message including the IP address assigned to the purifier 21. For example, in response to the DHCP request message of the first air purifier 21, the management server 1 sends a DHCP acknowledgment message including the IP address assigned to the first air purifier 21 to the first air purifier 21, To the purifier (1). The management server 1 can assign a dynamic IP address to the first air cleaner 21 by acting as a DHCP server to the first air cleaner 21 located in the communicable area of the management server 1 .

In step 305, the management server 1 stores the IP address assigned to the first air cleaner 21 in the storage 14 of the management server 1. The management server 1 stores the IP address assigned to the first air cleaner 21 in the storage 14 of the management server 1 when a wireless link is established with the first air cleaner 21, When the operation schedule data is transmitted to the purifier 21, it is used as the destination IP address of the data.

In step 306, the management server 1 establishes a wireless link with the first air cleaner 21. [ As described above, the management server 1 allocates an IP address to the first air cleaner 21, which is located in the communicable area of the management server 1 and serves as an access point, And establishes a wireless link between the air cleaners 21. The management server 1 and the first air cleaner 21 can exchange commands, operation schedule data, dust concentration data, or status data via a wireless link. Referring to Fig. 1, the third air cleaner 23 is also located in the communicable area of the management server 1 and serves as an access point. Accordingly, the third air cleaner 21 can also perform the steps 301 to 306 to establish a wireless link with the management server 1. [ A detailed description of a process of setting up a wireless link between APs in order to prevent the characteristic of the present embodiment of the present invention from being blurred will be omitted.

In step 307, the second air cleaner 22 located outside the communicable area of the management server 1 and serving as an access point is located in the communicable area of the second air cleaner 22 and functions as an access point The management server 1 or another air purifier. For example, the second air cleaner 22 searches the management server 1 or the first air cleaner 21 serving as an access point in such a manner as to broadcast a DHCP discovery message.

If the first air cleaner 21 is located within the communicable area of the second air cleaner 22 in step 308, the first air cleaner 21 sends a DHCP offer message to the second air cleaner 22 . As shown in Fig. 1, the second air cleaner 22 is located outside the communicable area of the management server 1, and is located within the communicable area of the first air cleaner 21. The management server 1 can not receive the DHCP discovery message from the second air cleaner 22 and the management server 1 can not transmit the DHCP discovery message to the second air cleaner 22. [ The first air cleaner 21 transmits a DHCP providing message to the second air cleaner 22 in response to the DHCP discovery message of the second air cleaner 22. For example, the DHCP providing message includes the MAC address of the second air cleaner 22, the IP address to be assigned to the second air cleaner 22 by the first air cleaner 21, and the like.

In step 309, the second air cleaner 22 sends an IP address allocation request message to the first air cleaner 21. For example, the second air cleaner 22 transmits a DHCP request message to the first air cleaner 21. The DHCP request message includes data such as the MAC address of the second air cleaner 22 and the IP address assigned to the second air cleaner 22 by the first air cleaner 21.

In step 310, the first air cleaner 21 assigns an IP address to the second air cleaner 22 that has transmitted the IP address allocation request message. When the second air cleaner 22 is located within the communicable area of the first air cleaner 21, the first air cleaner 21 responds to the IP address allocation request message transmitted from the second air cleaner 22 And transmits an IP address assignment message including the IP address assigned to the second air cleaner 22.

In step 311, the management server 1 stores the IP address assigned to the first air cleaner 21 in the storage 14 of the management server 1. When the management server 1 is connected to the second air cleaner 22 through the first air cleaner 21, the management server 1 stores the IP address allocated to the second air cleaner 22 in the storage, ), It is used as the destination IP address of the data.

In step 312, the first air cleaner 21 transmits the IP address assigned to the second air cleaner 22 to the management server 1. The first air cleaner 21 is connected to a wireless link between the management server 1 and the first air cleaner 21 and a wireless link between the first air cleaner 21 and the second air cleaner 22, The second air cleaner 22 is connected to the management server 1 via the wireless network to transmit the IP address of the second air cleaner 22 connected to the management server 1 to the management server 1 ) ≪ / RTI > network.

In step 313, the first air cleaner 21 establishes a wireless link with the second air cleaner 22. The first air cleaner 21 is disposed within the communicable area of the first air cleaner 21 and by assigning an IP address to the second air cleaner 22 serving as an access point, 2 < / RTI > The management server 1 and the second air cleaner are configured such that a wireless link between the management server 1 and the first air cleaner 21 and a wireless link between the first air cleaner 21 and the second air cleaner 22 are cascade- Operation schedule data, dust concentration data, or status data can be exchanged through a connected wireless chain network. 1, the fifth air cleaner 25 performs steps 307 through 312 to establish a wireless link with the third air cleaner 23 located in the communicable area of the management server 1, 1) and operation schedule data, dust concentration data, or status data.

In step 314, the management server 1 stores the IP address of the second air cleaner 22 received from the first air cleaner 21 in the storage. When the first air cleaner 21 with the wireless link established with the management server 1 establishes a wireless link with the second air cleaner 22, that is, the management server 1, When the second air cleaner 22 is connected, the IP address assigned to the second air cleaner 22 by the first air cleaner 21 is received and stored in the storage 14, When sending operation schedule data, it is used as destination IP address of data.

Although not shown in FIG. 3, the second air cleaner 22 can establish a wireless link with the fourth air cleaner 24, which is located outside the communicable area of the management server 1 and serves as an access point. The fourth air cleaner 24 broadcasts the DHCP discovery message to search for the air cleaner located in the communicable area of the fourth air cleaner 24 and serving as the access point. The second air cleaner 22 located in the communicable area of the fourth air cleaner 24 transmits a DHCP providing message in response to the DHCP discovery message of the fourth air cleaner 24. [ The fourth air cleaner 24 transmits an IP address allocation request message (DHCP request message) to the second air cleaner 22 in response to the DHCP providing message of the second air cleaner 22. [ The second air cleaner 22 responds to the IP address assignment request message of the fourth air cleaner 24 and transmits an IP address assignment message (DHCP acknowledgment message) including the IP address assigned to the fourth air cleaner 24 send.

In other words, when the second air cleaner 22 is found as a result of the search of the fourth air cleaner 24, the second air cleaner 22 assigns the IP address to the fourth air cleaner 24, And establishes a wireless link between the first air cleaner (22) and the fourth air cleaner (24). Accordingly, the management server 1 has a wireless link between the management server 1 and the first air cleaner 21, a wireless link between the first air cleaner 21 and the second air cleaner 22, A wireless chain network in which a wireless link between the first air cleaner 22 and the fourth air cleaner 24 are cascade-connected is constituted. The management server 1 can exchange status data and operation schedule data with the fourth air cleaner through this wireless chain network. The management server 1 transmits the operation schedule data of the fourth air cleaner 24 to the fourth air cleaner 24 through the wireless chain network connected to the fourth air cleaner 24, The operation can be managed.

In step 315, the first air cleaner 21 and the second air cleaner 22 measure the dust concentration of the air around each air cleaner by the dust sensors 216 and 226 installed in the respective air cleaners. The first air cleaner 21 measures the concentration of dust contained in the air in the space where the first air cleaner 21 is installed and the second air cleaner 22 measures the concentration of dust contained in the air in the space where the second air cleaner 22 is installed Measure the contained dust concentration.

In step 316, the second air cleaner 22 transmits dust concentration data indicating the dust concentration measured by the dust sensor to the first air cleaner 21 through the wireless link established with the first air cleaner 21. The second air cleaner 22 is connected to the wireless chain network between the management server 1 and the second air cleaner 22 in order to transmit the dust concentration data of the air around the second air cleaner 22 to the management server 1. [ And transmits the dust concentration data of the second air cleaner to the first air cleaner 21 to which the second air cleaner belongs.

The first air cleaner 21 sends dust concentration data indicating the dust concentration measured by the dust sensor 216 of the first air cleaner 21 to the management server 1 via the wireless link established with the management server 1, (1). At this time, the first air cleaner can transmit the dust concentration data of the first air cleaner (21) and the dust concentration data of the second air cleaner (22) sent from the second air cleaner (22) to the management server have. That is, the second air cleaner 22 is configured such that the wireless link between the management server 1 and the first air cleaner 21 and the wireless link between the first air cleaner 21 and the second air cleaner 22 are cascade- And transmits the dust concentration data of the second air cleaner 22 to the management server 1 through the wireless chain network.

In step 318, the management server 1 determines whether or not the first air cleaner 21 and the second air cleaner 22 are in contact with each other based on the received dust concentration data of the first air cleaner 21 and the second air cleaner 22. [ Create an action schedule. The control module 13 of the management server 1 generates an operation schedule for each air cleaner according to the dust concentration measured by each air cleaner. The operation schedule includes the operating intensity and operating time of the air cleaner. The control module 13 of the management server 1 determines the operation intensity and the operation intensity of each air cleaner based on the dust concentration measured by the first air cleaner 21 and the dust concentration measured by the second air cleaner 22, The operating time is determined.

The operation strength and operation time of the first air cleaner 21 and the second air cleaner 22 may be different depending on the degree of pollution of the air in the space where the first air cleaner 21 and the second air cleaner 22 are installed . When the dust concentration of the air around some air cleaners is high and the dust concentration around other air cleaners is low, only the air cleaner in a space with a high dust concentration operates for a long time at a high operating intensity, and the air cleaner By controlling the operation intensity to operate for a short time, all of the air cleaners can be prevented from operating for a long period of time with high operation strength, thereby reducing power consumption.

The management server 1 can be connected to a weather station server via the Internet and can receive a dust concentration indicating the concentration of fine dust in the air in a region where a plurality of air cleaners 21, 22, 23, 24, Data can be received. The control module 13 of the management server 1 can determine the operation intensity and the operation time for each of the plurality of air cleaners 21, 22, 23, 24, and 25 based on the dust concentration data received from the weather station server . For example, when the concentration of fine dust in the air in a region where a plurality of air cleaners 21, 22, 23, 24, and 25 are installed is very high, the management server 1 has a plurality of air cleaners 21, 22, 23, 24, and 25, respectively, to operate at high operating intensity and long operating time. On the contrary, when the concentrations of fine dusts in the air in the areas where the plurality of air cleaners 21, 22, 23, 24, and 25 are installed are low, the management server 1 has a large number of air cleaners 21, 22, 23, 24, 25 can be controlled to operate with a low operating intensity and a short operating time.

According to another embodiment of the present invention, the management server 1 can receive usage schedule data indicating a usage schedule at a place where each air cleaner is installed from a user. For example, the management server 1 may receive usage schedule data indicating the usage schedule of the place where the first air cleaner 21 is installed and the usage schedule of the place where the second air cleaner 22 is installed. When a plurality of air cleaners are installed in each classroom of a school, a use schedule indicating a class time and a break time, or a usage schedule indicating a business time and a break time when a plurality of air cleaners are installed in the office, ).

The management server 1 can determine the operation intensity and the operation time of each of the plurality of air cleaners based on the input use schedule and generate the operation schedule data indicating the operation strength and operation time of each of the plurality of air cleaners. For example, the management server 1 may operate the air purifier in such a manner as to weaken the operation intensity of the air purifier in order to reduce noises caused by the air cleaner during class hours or work hours, The operation schedule of each air cleaner can be generated. The present embodiment can efficiently purify the air without discomfort due to driving noise of the air cleaner by adjusting the use schedule of the air cleaner by the user.

In addition, the management server 1 determines the operation strength and operation time of each of the plurality of air cleaners based on both the dust concentration data received from the weather station server and the usage schedule data of the place entered by the user, It is possible to generate the operation schedule data indicating the operation strength and the operation time of the operation schedule data. The management server 1 controls the operation strength and the operation time of each of the plurality of air purifiers in consideration of both the fine dust concentration in the air in the area where a plurality of air cleaners are installed and the usage schedule of the place where a plurality of air cleaners are installed, It is possible to purify the air energy efficiently while minimizing the noise caused by the air cleaner.

In step 319, the management server 1 transmits the operation schedule data of the first air cleaner 21 including the operation intensity and the operation time of the first air cleaner 21 to the first air cleaner 21, To the first air cleaner (21). At this time, the management server 1 may transmit the operation schedule data of the second air cleaner 22 including the operation intensity and the operation time of the second air cleaner 22 connected to the first air cleaner 21.

The data processing module 212 of the first air cleaner 21 extracts the IP address from the operation schedule data transmitted from the management server 1 and if it matches the IP address of the first air cleaner 21, And inputs the data to the control module 214 of the first air cleaner 21. If the IP address of the second air cleaner 22 is not matched with the IP address of the first air cleaner 21, The operation schedule data of the second air cleaner 22 transmitted from the first air cleaner 1 is input.

In step 320, the first air cleaner 21 transmits the operation schedule data of the second air cleaner 22 transmitted from the management server 1 to the second air cleaner 22. According to steps 319-320, the management server 1 receives a radio link between the management server 1 and the first air cleaner 21 and a radio link between the first air cleaner 21 and the second air cleaner 22, The operation schedule data of the second air cleaner 22 is transmitted to the second air cleaner 22 through the connected wireless chain network.

According to steps 318-320, the management server 1 transmits the operation schedule data of the first air cleaner 21 to the first air cleaner 21 through the wireless link between the management server 1 and the first air cleaner 21, And transmits a second link between the wireless link between the management server 1 and the first air cleaner 21 and the wireless link between the first air cleaner 21 and the second air cleaner 22 in a cascade- The operations of the first air cleaner 21 and the second air cleaner 22 can be integrally managed by transmitting the operation schedule data of the second air cleaner 22 to the air cleaner 22. [

In step 321, the first air cleaner 21 and the second air cleaner 22 perform the filtering operation of the ambient air based on the respective operation schedule data transmitted from the management server 1. Each of the air cleaners operates the suction fans 215 and 225 in accordance with the operation schedule transmitted from the management server 1 to suck the surrounding air of each air cleaner and filter them by the filters 216 and 226, Cleanse. The control modules 214 and 224 of each air cleaner monitor the operating time of each air cleaner and sum the monitored operating time with the previous total operating time recorded in the storage 218 and 228 of each air cleaner, Calculate the total operating time of the purifier. The control modules 214 and 224 of each air cleaner store the total operation time of the calculated air cleaner in the storage units 218 and 228 again.

The second air cleaner 22 sends status data indicating the total operation time of the second air cleaner stored in the storage 228 of the second air cleaner 22 to the first air cleaner 21, To the first air cleaner (21). The second air cleaner 22 is connected to the first air cleaner 21 via the wireless link between the management server 1 and the first air cleaner 21 and the first air cleaner 21, The status data of the second air cleaner 22 is transmitted to the first air cleaner 21 to the management server 1 through the wireless chain network in which the wireless link between the second air cleaner 22 and the second air cleaner 22 are cascade- do.

In step 323, the first air cleaner 21 transmits status data representing the total operation time of the first air cleaner 21 stored in the storage 218 of the first air cleaner 21 to the management server 1, To the management server 1 via a link. At this time, the first air cleaner can transmit the status data of the second air cleaner 22 to the management server 1 together with the status data of the first air cleaner 21. The management server 1 can determine the filter usage amount of each air cleaner based on the total operation time of the first air cleaner 21 and the second air cleaner 22. [ The control module 13 of the management server 1 can inform the user of the filter replacement timing based on the determined filter usage amount of each air cleaner. For example, when the total operation time of the first air cleaner 21 exceeds the critical operation time, the control module 13 of the management server 1 determines that the filter replacement time of the first air cleaner 21 is , The management server 1 can transmit the filter replacement alarm of the first air cleaner 21 to the smartphone of the user through the external network connected to the management server.

[ The management server 1 transmits the operation schedule data to each of the plurality of air cleaners through the wireless chain network in which the wireless links set in this manner are cascade-connected, so that one management server 1 is connected to the plurality of air cleaners 21 , 22, 23, 24, 25) can be integrally managed. Accordingly, even if the plurality of air cleaners 21, 22, 23, 24, and 25 are installed apart from each other, all of the air cleaners can be managed through the management server 1 without having to individually control the air cleaners Therefore, it enables the integrated management of a plurality of air cleaners.
