The gateway 2000 can identify the external device 1000 connected to the gateway 2000 in step S200. As the external device 1000 is connected to the gateway 2000, the gateway 2000 can receive the device information of the external device 1000 from the external device 1000. [ In addition, the gateway 2000 can identify the external device 1000 based on the device information received from the external device 1000. [ The device information of the external device 1000 is information indicating the attributes of the external device 1000 and the external device 1000. The device information includes information such as an identification value of the external device 1000, The type and the attribute of the sensing data generated by the sensing device 1000, and the sensing period of the external device 1000.

In addition, the gateway 2000 can store device information of the external device 1000. The gateway 2000 may store the device information of the external device 1000 in association with the service to be provided by the device 3000 or the server 4000. [ In this case, the gateway 2000 can receive the service information from the device 3000 or the server 4000, and can identify, based on the received service information, which service the external device 1000 is associated with. The service information includes, for example, the identification value of the service, the type and number of external devices for the service, the priority of the external device for the service, the type and number of the sensing data for the service, Priority, and the like.

In step S210, the gateway 2000 can set a data transmission rule of the sensing data. The data transmission rule may be a rule as to how the sensing data is received from an external device 1000 according to the resource occupancy rate of the gateway 2000. [ The gateway 2000 can set the data transmission rule according to the preset reference based on the device information of the external device 1000 and the service information of the service provided by the device 3000 or the server 4000. [ Alternatively, the gateway 2000 may set data transmission rules based on user input.

For example, an external device to be used for a service, an external device to be paused, a data processing method of sensing data, A transmission period, a data transmission amount, and a rule regarding whether to transmit reservation data of the sensing data. For example, the gate weight 2000 may set a rule for determining a data transmission period of the sensing data, a data transmission amount, and whether to transmit the sensing data in accordance with at least one of season, weather, and time. For example, on a dry day, the gateway 2000 can shorten the transmission period of the sensing data related to the fire alarm service. In addition, for example, the gateway 2000 can set the transmission period of the sensing data to be longer at night than the daytime.

In step S220, the gateway 2000 may monitor the resource occupancy of the gateway 2000. [ The resource occupancy rate of the gateway 2000 can be determined based on at least one of the CPU usage, the memory usage, the buffer memory usage, and the communication state of the gateway 2000, for example. For example, the resource occupancy rate can be determined according to how much the CPU of the gateway 2000 is currently used (e.g., how many percent of the maximum performance of the CPU is currently being used). Also, for example, the resource occupancy rate can be determined depending on how many percent of the total capacity of the memory of the gateway 2000 is currently used. Also, for example, the resource occupancy rate can be determined depending on how much data is currently stored in the buffer memory of the gateway 2000. [ However, the present invention is not limited thereto, and the resource occupation rate of the gateway 2000 can be determined according to the usage state of various resources other than the CPU, the memory, and the buffer.

 In addition, the gateway 2000 can determine whether the resource occupancy rate exceeds a preset threshold value.

In step S300, the external device 1000 can provide the gateway 2000 with the device information of the external device 1000. [ The external device 1000 may communicate with the gateway 2000 and may transmit the device information of the external device 1000 to the gateway 2000 in order to register the external device 1000 with the gateway 2000. [ The device information may include, for example, an identification value of the external device 1000, a type of the external device 1000, a kind of sensing data, an attribute of the sensing data, and information about a sensing period. The gateway 2000 can identify the type of the device and the type of the sensing data generated by the external device 1000 for each external device 1000 based on the received device information.

The device 3000 or the server 4000 may provide the service information to the gateway 2000 in step S310. The service information is information related to the service provided by the device 3000 or the server 4000, for example, the identification value of the service, the type and number of the external device for the service, and the priority of the external device for the service The type and number of sensing data for the service, and the priority of the sensing data for the service, and the like, but the present invention is not limited thereto. The services may include, but are not limited to, home network services, security services, fire alarm services, power management services, and content sharing services, for example.

In step S320, the gateway 2000 may determine an external device associated with the service. Based on the service information, the gateway 2000 can determine which external device is needed for providing the service, and can determine some or all of the external devices connected to the gateway 2000 as devices related to the service.

In step S330, the gateway 2000 can store the device information of the determined external device 1000 in association with the service. For example, the gateway 2000 can add a field indicating the identification value of the service to the device information table of the external device 1000, and record the identification value of the service associated with the external device 1000 in the added field have. However, it is not limited thereto.

5, the service information table includes a service ID field 50, a required device field 52, a priority 1 field 54, a priority 2 field 56, and a priority 3 field 58 can do.

In the service ID field 50, an identification value indicating a service can be recorded. In the required device field 52, information on the type and number of external devices 1000 required for providing a service can be recorded. For example, in the required device field 52, " two temperature sensors ", " three gas detection sensors " and " one fire alarm "

In the priority 1 field 54, the priority 2 field 56 and the priority 3 field 58, among the external devices 1000 necessary for providing the service, the priority of the external device 1000 corresponding to each priority The type and number may be recorded.

For example, with respect to device A, which is a temperature sensor, " home control service B " and " fire alarm service A "

7 is a flowchart of a method by which a gateway 2000 according to some embodiments establishes a data transmission rule of sensing data.

In step S700, the gateway 2000 can determine the external device 1000 corresponding to the resource occupancy rate. The gateway 2000 can determine an external device 1000 required for providing a service according to the interval of the resource occupation rate of the gateway 2000. The gateway 2000 can determine the external device 1000 corresponding to the resource occupancy rate of the gateway 2000 based on the device information of the external device and the service information of the device 3000 or the server 4000. [ The gateway 2000 may not select the external device 1000 not related to the service. In addition, the gateway 2000 may select an external device 1000 that is indispensable among the external devices 1000 required for the service, and may not select an external device 1000 that is not essential.

For example, in the case where the external device 1000 required for the fire alarm service includes two temperature sensors, three gas sensors, and one fire alarm, the gateway 2000 receives external resources corresponding to the resource occupation rate of 0 to 70% As the device 1000, a temperature sensor A, a temperature sensor B, a gas sensor A, a gas sensor B, a gas sensor C and a fire alarm A can be selected. Also, the gateway 2000 can select the temperature sensor A, the gas detection sensor A, the gas detection sensor B, and the fire alarm A as the external device 1000 corresponding to the resource occupancy rate of 70% to 100% of the gateway.

In step S710, the gateway 2000 can determine the data providing method of the sensing data to be received from the determined external device 1000. [ The data providing method may include, for example, a method of collecting and providing sensing data, a method of separately providing sensing data, and a method of calculating and providing an average value of sensing data. The data providing method may include a method of transmitting only the changed data compared with the sensing data previously transmitted to the gateway 2000 among the newly generated sensing data in the external device 1000. The gateway 2000 can determine the data providing method of the sensing data in consideration of the real-time performance of the sensing data and the size of the sensing data. The gateway 2000 may determine that the external device 1000 separates a large amount of sensing data and decide that the external device 1000 should collect a small amount of sensing data. In addition, the gateway 2000 may determine that the external device 1000 transmits the average value of the sensing data when the attribute of the sensing data is a number value.

For example, in the fire alarm service, the gateway 2000 can detect a temperature sensor A, a temperature sensor B, a gas sensor A, a gas sensor B, a gas sensor C, The alarm A can decide to send the sensing data to the gateway 2000 without any additional processing. In the case where the gateway 2000 has a resource occupancy rate of 70% to 100% of the gateway, the temperature sensor A decides to transmit the average value of the sensing data, the gas sensing sensor A decides to separately transmit the sensing data, The sensor B can decide to collect and transmit the sensing data.

In addition, the gateway 2000 can determine whether the resource occupation rate is maintained for a predetermined time or longer with exceeding a preset threshold value.

In Fig. 9, although the gateway 2000 has been described as determining resource occupancy based on CPU usage and / or memory usage, it is not limited thereto. For example, the gateway 2000 can determine the resource occupancy rate according to various resource usage states such as buffer memory usage, communication status, and the like, as well as the CPU usage and memory usage of the gateway 2000. [ In addition, the criteria for determining the resource occupancy rate can be set variously.

For example, the first external device 1100, the second external device 1200, the third external device 1300, and the fourth external device 1400 can transmit the sensing data to the gateway 2000 without any additional processing have. The transmission period of the sensing data provided from the first external device 1100, the second external device 1200, the third external device 1300, and the fourth external device 1400 may have a default value.

The gateway 2000 can monitor the gateway's CPU occupancy and memory occupancy. Further, the gateway 2000 can determine whether the CPU occupation rate and / or memory occupancy rate of the gateway exceeds a predetermined threshold value.

As a result of the determination in step S1040, if the resource occupation rate of the gateway 2000 does not exceed the predetermined threshold value, the gateway 2000 can repeat step S1040.

As a result of the determination in step S1040, if the resource occupancy rate of the gateway 2000 exceeds a predetermined threshold value, the gateway 2000 can perform step S1050.

In step S1050, the gateway 2000 may identify a data transmission rule corresponding to a resource occupancy rate. The gateway 2000 can identify a data transmission rule corresponding to a resource occupancy rate of the gateway 2000 using a pre-generated data transmission rule table.

In steps S1060 to S1090, the gateway 2000 transmits the first external device 1100, the second external device 1200, the third external device 1300, and the fourth external device 1400 according to the identified data transmission rule. It is possible to control the transmission of the sensing data.

In step S1060, the gateway 2000 may transmit a control message to the first external device 1100 to transmit the average value of the sensing data at a preset time.

In step S1070, the gateway 2000 may send a control message to the second external device 1200 to separately transmit sensing data and change the transmission period.

In step S1080, the gateway 2000 may send a control message to the third external device 1300 to collect the sensing data and transmit it.

Further, in step S1090, the gateway 2000 may transmit a control message to the fourth external device 1400 to suspend the transmission of the sensing data.

The first external device 1100 and the second external device 1200 can then transmit the sensing data to the gateway 2000 based on the control message received from the gateway 2000 .

The gateway 2000 also provides sensing data received from the first external device 1100, the second external device 1200 and the third external device 1300 to the device 3000 or the server 4000, The server 3000 or the server 4000 can provide a predetermined service to the user.

11 is a diagram showing an example of a control message that the gateway 2000 according to some embodiments transmits to the external device 1000 to control transmission of sensing data from the external device 1000. [

Referring to FIG. 11, the control message may have a value of, for example, 2 bytes. In this case, the control message includes a 1-bit value 110 indicating the type of the control message, a 3-bit value 112 indicating the data providing method, a 4-bit value 114 indicating the sub- And a value 116 of 8 bits for changing the transmission period of the data.

The 1-bit value 110 indicating the type of the control message may be a value indicating whether the control message is a message for suspending transmission of the sensing data of the external device 1000. For example, when the 1-bit value 110 indicating the type of the control message is " 1 ", the control message may be a message for granting and controlling transmission of the sensing data of the external device 1000. [ Also, for example, when the 1-bit value 110 indicating the type of the control message is " 0 ", the control message may be a message for suspending transmission of the sensing data of the external device 1000. [ On the other hand, when the 1-bit value 110 indicating the type of the control message is " 0 ", and the remaining bits in the control message are all 1, the control message indicates that the external device 1000 pauses the sensing data transmission, And accumulate and store the sensing data.

The value of 3 bits (112) indicating the data providing method may be a value indicating how the external device 1000 should process and provide the sensing data. For example, when the value 112 of 3 bits indicating the data providing method is " 0 ", the control message may be a message for controlling the external device 1000 not to process the sensing data separately. Also, for example, when the value 112 of 3 bits indicating the data providing mode is "1", the control message may be a message for allowing the external device 1000 to transmit the average value of the sensing data. Also, for example, when the value 112 of 3 bits indicating the data providing mode is "2", the control message may be a message for allowing the external device 1000 to collect and transmit the sensing data. Further, for example, when the value 112 of 3 bits indicating the data providing method is " 3 ", the control message may be a message for allowing the external device 1000 to divide and transmit the sensing data. For example, when the 3 bits value 112 indicating the data providing mode is " 4 ", the control message indicates that the external device 1000 has compared only the changed sensing data with the previous sensing data Message to be transmitted. Further, for example, when the value 112 of 3 bits indicating the data providing method is " 5 ", the control message may be a message for allowing the external device 1000 to collect and transmit the average value of the sensing data .

A value 114 of 4 bits indicating sub-rules of the data providing scheme may indicate the number of times related to data processing. For example, a 4-bit value 114 indicating a sub rule of a data providing scheme may indicate the number of times the sensing data is divided, the number of times the sensing data is collected, or how many sensing data should be averaged.

A value 116 of 8 bits for changing the transmission period of the sensing data may indicate the transmission period of the sensing data.

In step S1200, the gateway 2000 can determine whether the resource occupation rate of the gateway 2000 is smaller than a preset threshold value. As the resource occupancy rate of the gateway 2000 is lower than a predetermined threshold value, the gateway 2000 can be in a state of being able to communicate smoothly with the external device 1000 without any restriction. The gateway 2000 can determine whether the CPU occupancy rate is smaller than a predetermined threshold value, whether the memory occupancy rate is smaller than a predetermined threshold value, whether the CPU occupancy rate and the memory occupancy rate are both smaller than a preset threshold value. Also, the gateway 2000 can determine whether the average value of the CPU occupancy rate and the memory occupancy rate is smaller than a preset threshold value. Further, the gateway 2000 can determine whether the resource occupancy rate is maintained for a predetermined time or longer, while being smaller than a predetermined threshold value.

20 is a block diagram of a gateway 2000 in accordance with some embodiments.

As shown in FIG. 20, the gateway 2000 according to some embodiments may include a memory 2100, a communication unit 2200, and a control unit 2300. The communication unit 2200 may include a wireless communication unit 2210 and a wired communication unit 2220.

The control unit 2300 can identify the external device 1000 connected to the gateway 2000. As the external device 1000 is connected to the gateway 2000, the control unit 2300 can receive the device information of the external device 1000 from the external device 1000. [ In addition, the control unit 2300 can identify the external device 1000 based on the device information received from the external device 1000. [ The device information of the external device 1000 is information indicating the attributes of the external device 1000 and the external device 1000. The device information includes information such as an identification value of the external device 1000, The type and the attribute of the sensing data generated by the sensing device 1000, and the sensing period of the external device 1000.

[ The control unit 2300 may store the device information of the external device 1000 in the memory 2100 in association with the service to be provided by the device 3000 or the server 4000. [ In this case, the control unit 2300 can receive service information from the device 3000 or the server 4000, and can identify which service is associated with the external device 1000 based on the received service information. The service information includes, for example, the identification value of the service, the type and number of external devices for the service, the priority of the external device for the service, the type and number of the sensing data for the service, Priority, and the like.

For example, the control unit 2300 may add a field indicating the identification value of the service to the device information table of the external device 1000, and record the identification value of the service associated with the external device 1000 in the added field have. However, it is not limited thereto.

The control unit 2300 can set the data transmission rule of the sensing data. The data transmission rule may indicate a rule as to how the sensing data is received from an external device 1000 according to the resource occupancy rate of the gateway 2000. The control unit 2300 can set the data transmission rule according to the preset reference based on the device information of the external device 1000 and the service information of the service provided by the device 3000 or the server 4000. [ Alternatively, the control unit 2300 may set a data transmission rule based on a user input.

The data transmission rules can be set to be distinguishable according to the resource occupancy of the gateway 2000. For example, an external device to be used for a service, an external device to be paused, a data processing method of sensing data, A transmission period, and a rule regarding whether to transmit reservation data of the sensing data.

Specifically, the control unit 2300 can determine the external device 1000 corresponding to the resource occupancy rate. The control unit 2300 can determine the external device 1000 required for providing the service according to the interval of the resource occupation rate of the gateway 2000. [ The control unit 2300 can determine the external device 1000 corresponding to the resource occupation rate of the gateway 2000 based on the device information of the external device and the service information of the device 3000 or the server 4000. [ The control unit 2300 may not select the external device 1000 not related to the service. In addition, the gateway 2000 may select an external device 1000 that is indispensable among the external devices 1000 required for the service, and may not select an external device 1000 that is not essential.

For example, when the external device 1000 required for the fire alarm service includes two temperature sensors, three gas sensors, and one fire alarm, the control unit 2300 controls the external As the device 1000, a temperature sensor A, a temperature sensor B, a gas sensor A, a gas sensor B, a gas sensor C and a fire alarm A can be selected. Also, the controller 2300 can select the temperature sensor A, the gas sensor A, the gas sensor B, and the fire alarm A as the external device 1000 corresponding to 70% to 100% of the resource occupancy rate of the gateway.

The control unit 2300 can determine the data providing method of the sensing data to be received from the determined external device 1000. [ The data providing method may include, for example, a method of collecting and providing sensing data, a method of separately providing sensing data, and a method of calculating and providing an average value of sensing data. The data providing method may include a method of transmitting only the changed data compared with the sensing data previously transmitted to the gateway 2000 among the newly generated sensing data in the external device 1000. The controller 2300 can determine the data providing method of the sensing data in consideration of the real time characteristics of the sensing data and the size of the sensing data. The control unit 2300 may determine that the external device 1000 should separate the large amount of sensing data and decide that the external device 1000 should collect a small amount of sensing data. Also, when the attribute of the sensing data is a number value, the controller 2300 can determine that the external device 1000 transmits the average value of the sensing data.

For example, in the fire alarm service, the control unit 2300 controls the temperature sensor A, the temperature sensor B, the gas sensing sensor A, the gas sensing sensor B, the gas sensing sensor C, and the fire sensor A, when the resource occupancy rate of the gateway is 0 to 70% The alarm A can decide to send the sensing data to the gateway 2000 without any additional processing. The control unit 2300 determines that the temperature sensor A transmits the average value of the sensing data when the resource occupancy rate of the gateway is 70 to 100%, the gas sensing sensor A decides to transmit the sensing data separately, The sensor B can decide to collect and transmit the sensing data.

The control unit 2300 can determine the data transmission period of the sensing data to be received from the determined external device 1000. [ The control unit 2300 can determine the data transmission period in consideration of the real time characteristics of the sensing data, the data size, and the data providing method of the sensing data.

For example, in the fire alarm service, the control unit 2300 controls the temperature sensor A, the temperature sensor B, the gas sensing sensor A, the gas sensing sensor B, the gas sensing sensor C, and the fire sensor A, when the resource occupancy rate of the gateway is 0 to 70% The alarm A can decide to send the gateway 2000 the sensing data according to the default period value. In the case where the resource occupancy rate of the gateway is 70 to 100%, the control unit 2300 determines that the temperature sensor A transmits an average value of the sensing data every 30 minutes, and the gas sensing sensor A sends the separated sensing data every 2 minutes It can decide to transmit.

The control unit 2300 can determine whether or not to transmit the sensing data to be received from the determined external device 1000. The control unit 2300 can determine whether or not to transmit the sensing data in consideration of the real time characteristics of the sensing data, the data size, and the data providing method of the sensing data.

For example, in the fire alarm service, the control unit 2300 can determine that the gas sensing sensor B should reserve the collected sensing data at a preset time, when the resource occupancy rate of the gateway is 70 to 100%.

The control unit 2300 may monitor the resource occupancy of the gateway 2000. [ The control unit 2300 can monitor the CPU occupancy rate of the gateway 2000 and the memory occupancy rate of the gateway 2000. [ Also, the control unit 2300 can determine whether the resource occupancy rate exceeds a preset threshold value. The control unit 2300 can determine whether the CPU occupation rate exceeds a predetermined threshold value, whether the memory occupancy rate exceeds a predetermined threshold value, and whether both the CPU occupancy rate and the memory occupancy rate exceed a preset threshold value. The control unit 2300 can determine whether the average value of the CPU occupancy rate and the memory occupancy rate exceeds a predetermined threshold value. The control unit 2300 can determine whether the resource occupancy rate is maintained for a predetermined time or longer in a state where the resource occupancy rate exceeds a predetermined threshold value.

The control unit 2300 may transmit the control message related to the transmission of the sensing data to the external device 1000 according to the data transmission rule. The control unit 2300 identifies a data transmission rule corresponding to the current resource occupation rate of the gateway 2000 and transmits a control message related to the transmission of sensing data to the external device 1000 in order to control the external device 1000 according to the identified data transmission rule To the device (1000). The control message transmitted to the external device 1000 may include information such as, for example, whether to suspend the external device, data providing method of sensing data, data transmission period, and the like.

On the other hand, the control unit 2300 can determine whether the resource occupation rate of the gateway 2000 is smaller than a preset threshold value. If the resource occupancy rate is not smaller than the preset threshold value, the control unit 2300 can maintain the current data transmission rule without changing. If the resource occupancy rate is smaller than the preset threshold value, the control unit 2300 can request the external device 1000 to transmit the sensing data according to the default rule. The control unit 2300 may transmit a control message to the external device 1000 to allow the external device 1000 to transmit the sensing data according to the default rule. The default rule is a data transmission rule in the case where the gateway 2000 can smoothly use the resource, and may be a data transmission rule having a default value.

21 is a block diagram of an external apparatus 1000 according to some embodiments.

Referring to FIG. 21, the external device 1000 may include a sensing unit 1100, a communication unit 1200, and a control unit 1300. The gateway 2000 may be connected to various external devices 1000 and the external device 1000 may be connected to the sensing unit 1100, the communication unit 1200 and the control unit 1300 in addition to the sensing unit 1100, Configuration.

The sensing unit 1100 can generate sensing data. The sensing unit 1100 can generate predetermined sensing data by using a temperature sensor, a humidity sensor, an acoustic sensor, a motion sensor, a proximity sensor, a gas sensing sensor, and a heat sensing sensor, for example. In addition, the sensing unit 1100 can generate sensing data at a predetermined cycle by being controlled by a control unit 1300, which will be described later.

The communication unit 1200 receives information related to the transmission of the sensing data from the gateway 2000 and can transmit the sensing data to the gateway 2000. [

The control unit 1300 can provide the gateway 2000 with the device information of the external device 1000. [ The control unit 1300 establishes communication with the gateway 2000 using the communication unit 1200 and transmits the device information of the external device 1000 to the gateway 2000 in order to register the external device 1000 in the gateway 2000 Lt; / RTI > The device information may include, for example, an identification value of the external device 1000, a type of the external device 1000, a kind of sensing data, an attribute of the sensing data, and information about a sensing period.

First, the control unit 1300 may provide sensing data to the gateway 2000 according to a default rule. For example, the control unit 1300 may transmit the sensing data to the gateway 2000 without any additional processing. In this case, the transmission period of the sensing data provided from the control unit 1300 may have a default value.

Thereafter, when the resource occupancy rate of the gateway 2000 exceeds a predetermined threshold, the controller 1300 can receive information on the data transmission rule corresponding to the resource occupancy rate from the gateway 2000. [ The data transmission rule may be a rule as to how the gateway receives the sensing data from an external device according to the resource occupancy rate of the gateway. The data transfer rule is, for example, an external device to be used for a service, an external device to be paused, a data providing method of the sensing data, a data transfer cycle of the sensing data, a data transfer amount, . ≪ / RTI >

In addition, the control unit 1300 may provide sensing data to the gateway 2000 according to the received data transmission rule. For example, the control unit 1300 can transmit the average value of the sensing data to the gateway 2000 at a preset time. Also, for example, the control unit 1300 can separately transmit the sensing data to the gateway 2000 and change the transmission period. Further, for example, the control unit 1300 may collect the sensing data and transmit it to the gateway 2000. Also, for example, the control unit 1300 can suspend the transmission of the sensing data.

Thereafter, when the resource occupation rate of the gateway 2000 falls below a preset threshold value, the controller 1300 can provide the sensing data to the gateway 2000 according to the default rule.

The gateway 2000 can control at least one external device 1000 and includes a communication unit for receiving sensing data from the external device 1000 and a resource occupancy rate of the gateway used for processing the received sensing data, And a controller for determining a processing period of the sensing data based on at least one of status information of the external apparatus and the number of the external apparatuses.

22 is a flowchart illustrating a process of changing the processing cycle of sensing data received from a plurality of external devices 1000 as the gateway 2000 receiving the sensing data from a plurality of external devices 1000 according to some embodiments changes the resource occupancy rate And the like.

Referring to FIG. 22, the external device 1000 can transmit data sensed to the gateway 2000. The gateway 2000 can receive the sensing data from the external device 1000 (step S2201). The gateway 2000 determines whether the resource occupancy rate of the gateway 2000 is smaller than the threshold value (step S2203). If the resource occupancy rate of the gateway 2000 is smaller than the threshold value, the gateway 2000 processes the received sensing data as the first period (step S2205 ), And if the resource occupancy rate is larger than the threshold value, the received sensing data may be processed in the second period (step S2207). That is, the gateway 2000 can change the processing period of the received sensing data based on the resource occupancy rate of the gateway 2000. [

For example, a temperature sensor, which is an external device 1000, is connected to the gateway 2000, and a temperature sensor transmits temperature data sensed by the gateway 2000 every one second. The gateway 2000 can normally process the received temperature data at a cycle of 1 second when the resource occupancy rate of the gateway 2000 is equal to or lower than the threshold value of 70%. If the resource occupancy rate is higher than the threshold value by 90%, the gateway 2000 can process the received temperature data in a cycle of 2 seconds by changing the processing cycle of the received temperature data.

The gateway 2000 may request the temperature sensor to change the data transmission period if the resource occupancy of the gateway 2000 is higher than the threshold. For example, when the resource occupation rate of the gateway 2000 is equal to or less than the threshold value of 70%, the gateway 2000 may request the temperature sensor to send the temperature data sensed by the gateway 2000 to the gateway 2000 once per one second . Also, for example, if the resource occupancy rate of the gateway 2000 is higher than the threshold value of 90%, the gateway 2000 can request the gateway 2000 to send the sensed data to the gateway 2000 once every 2 seconds.

Also, when the resource occupancy rate is higher than the threshold value, the gateway 2000 may only receive the sensed data from the temperature sensor once per second, and may not process the received sensed data.

The gateway 2000 can determine the reception period of the sensing data received from the external device 2000 based on the resource occupancy rate of the gateway 2000. [ The gateway 2000 receives the sensing data in the first cycle from the external device 2000 when the resource occupancy rate is lower than the threshold value and receives the sensing data in the second cycle from the external device 2000 when the resource occupancy rate is higher than the threshold value For example, the gateway 2000 receives sensing data from the external device 1000 at a cycle of 1 second when the resource occupation rate of the gateway 2000 is 70% or less, which is the threshold value, and when the resource occupancy rate is 90% , It is possible to receive the sensing data at a cycle of 2 seconds.

23 is a diagram illustrating a method of changing the sensing data processing cycle received from a plurality of external devices 1000 when the gateway 2000 receiving the sensing data from a plurality of external devices 1000 according to some embodiments is in maintenance FIG.

When the gateway 2000 is under maintenance, the gateway 2000 may include a case where the gateway 2000 changes or updates software associated with the operation of the gateway 2000. For example, when the gateway 2000 is under maintenance, when updating the driver software of the gateway 2000, when updating the application software installed in the gateway 2000, and when updating the operating system installed in the gateway 2000 But the present invention is not limited thereto.

Referring to FIG. 23, the external device 1000 can transmit data sensed to the gateway 2000. The gateway 2000 can receive the sensing data from the external device 1000 (step S2301). The gateway 2000 determines whether maintenance is in progress (step S2303). If the gateway 2000 is under maintenance, the gateway 2000 processes the received sensing data in a first cycle (step S2305) The received sensing data can be processed in the second period (step S2307). That is, the gateway 2000 can change the processing period of the received sensing data based on whether the gateway 2000 is in maintenance or not.

For example, a temperature sensor, which is an external device 1000, is connected to the gateway 2000, and a temperature sensor transmits temperature data sensed by the gateway 2000 every one second. When the gateway 2000 does not update the software, it can process the received temperature data normally at a cycle of 1 second. When the gateway 2000 is updating the software, the gateway 2000 can process the temperature data every 2 seconds by changing the processing period of the received temperature data.

The gateway 2000 may request the temperature sensor to change the data transmission period when software is being updated. For example, while the gateway 2000 is not performing a software update, the gateway 2000 may cause the temperature sensor to send temperature data sensed by the gateway 2000 once per second. When the gateway 2000 is under software update, the gateway 2000 may request the temperature sensor to send the sensed data once every 2 seconds.

Further, when the gateway 2000 is in the process of updating the software, the gateway 2000 may only receive the sensed data from the temperature sensor once per second, and may not process the received sensed data.

FIG. 24 is a diagram illustrating a sensing data processing cycle received from a plurality of external apparatuses 1000 according to the number of external apparatuses 1000 by a gateway 2000 receiving sensing data from a plurality of external apparatuses 1000 according to some embodiments Fig.

Referring to FIG. 24, the external device 1000 can transmit data sensed to the gateway 2000. The gateway 2000 can receive the sensing data from the external device 1000 (step S2401). The gateway 2000 determines whether the number of the external devices 1000 is smaller than the set value (step S2403). If the number of the external devices 1000 is smaller than the set value, the gateway 2000 processes the received sensing data in the first cycle If the number of the external devices 1000 is larger than the set value, the received sensing data may be processed in the second period (step S2407). That is, the gateway 2000 can change the processing cycle of the received sensing data based on the number of the external devices 1000. [

For example, when the set value is 10, when the number of the external devices 1000 is less than 10 in the gateway 2000, the gateway 2000 can process the sensing data received from the external device 1000 every 1 second have. When 15 external devices 1000 are connected to the gateway 2000, the gateway 2000 can process the sensing data received from the external device 1000 every 2 seconds.

In addition, the gateway 2000 may request the external device 1000 to change the data transmission period when the external device 1000 is connected with more than the set value. For example, when seven external devices 1000 are connected to the gateway 2000, the gateway 2000 controls the external device 1000 to send the sensing data to the gateway 2000 once per second . When the external device 1000 is connected to the gateway 2000, which is larger than the set value, the gateway 2000 may request the temperature sensor to send the sensed data once every 2 seconds.

When the external device 1000 is connected to the gateway 2000, which is larger than the set value, 15, the sensed data may be received only once per second, and the received sensing data may not be processed.

The gateway 2000 can determine the reception period of the sensing data received from the external device 1000 based on the number of the external devices 1000. The gateway 2000 receives the sensing data in the first cycle from the external device 1000 when seven external devices 1000 are connected and the second external device 1000 receives the sensing data from the external device 1000 when fifteen external devices 1000 are connected. It is possible to receive the sensing data in a cycle. For example, the gateway 2000 receives sensing data from the external device 1000 every one second when the external device 1000 connected to the gateway 2000 has seven, and the external device 1000 connected to the gateway 2000 15, the sensing data can be received every two seconds.

25 is a block diagram illustrating a configuration of a gateway 2000 that receives sensing data from a plurality of external devices 1000 according to some embodiments and receives the sensing data from a plurality of external devices 1000 according to the state of the external device 1000, And a method of changing the sensing data processing cycle.

Referring to FIG. 25, the external device 1000 may transmit sensed data to the gateway 2000. The gateway 2000 can receive the sensing data from the external device 1000 (step S2501). The gateway 2000 determines whether the battery remaining amount of the external device 1000 is greater than the threshold value (step S2503). If the battery remaining amount of the external device 1000 is larger than the threshold value, the gateway 2000 processes the received sensing data in the first period If the battery remaining amount of the external device 1000 is smaller than the threshold value, the received sensing data may be processed in the second cycle (step S2507). That is, the gateway 2000 can change the processing cycle of the received sensing data based on the state of the external device 1000, for example, the battery remaining amount of the external device 1000. [ In this case, the gateway 2000 can receive from the external device 100 information on the remaining battery power of the external device 1000. [ For example, the gateway 2000 can receive information regarding the battery remaining amount of the external device 1000 from the external device 100 at a predetermined period or when a specific event occurs. The gateway 2000 receives status information of the external device 1000 (for example, information indicating the remaining battery level, information indicating the resource occupancy rate, information indicating the network status, and the like) while receiving the sensing data from the external device 1000 .

When the battery remaining amount of the external device 1000 is greater than the threshold value, the external device 1000 transmits the sensing data to the gateway 2000 in the first cycle, and the gateway 2000 processes the received sensing data in the first cycle . When the battery remaining amount of the external device 1000 is smaller than the threshold value, the external device 1000 transmits the sensing data to the gateway 2000 in the second cycle. The gateway 2000 may process the received sensing data in a second period.

For example, when the remaining battery level of the external device 1000 is 80%, the external device 1000 transmits sensing data to the gateway 2000 at a cycle of 1 second, and the gateway 2000 receives the sensing data from the external device 1000 The sensing data can be processed in a cycle of 1 second. When the battery remaining amount of the external device 1000 is 20%, the external device 1000 transmits the sensing data to the gateway 2000 at a cycle of 2 seconds, and the gateway 2000 transfers the sensing data received from the external device 1000 to 2 It can be processed in seconds.

In addition, the gateway 2000 may request the external device 1000 to change the data transmission period when the battery remaining amount of the external device 1000 is smaller than the threshold value. For example, when the threshold value is 30%, when the battery remaining amount of the external device 1000 is 80% larger than the threshold value, the external device 1000 can send the sensing data to the gateway 2000 once per one second. If the battery remaining amount of the external device 1000 is 20% smaller than the threshold value, the gateway 2000 may request the external device 1000 to send the sensed data once every 2 seconds.

Also, if the battery remaining amount of the external device 1000 is 20%, which is less than the threshold value of 30%, the sensing data is received once per second from the external device 1000, but the received sensing data may not be processed.

Also, the gateway 2000 can determine the reception period of the sensing data received from the external device 1000 based on the battery remaining amount of the external device. When the battery remaining amount of the external device 1000 is greater than the threshold value, sensing data is received from the external device 1000 in the first cycle, and when the battery remaining amount of the external device 1000 is less than the threshold value, And receives data. For example, when the threshold value is 30%, the gateway 2000 receives the sensing data from the external device 1000 at a cycle of 1 second when the battery remaining amount of the external device is 80%, and when the battery remaining amount of the external device is 20% The gateway 2000 can receive the sensing data from the external device 1000 every two seconds.
