The controller 2140 uses the communicator 2130 to establish communication with the gateway 2000, and can transmit the component information of the external device 1000 to the gateway 2000 to register the external device 1000 to the gateway 2000. The device information may include information on, for example, the identification value of the external device 1000, the type of the external device 1000, the type of sensing data, the nature of the sensing data, and the sensing period.

First, the controller 2140 can provide the sensing data to the gateway 2000 according to the default transmission rule. For example, the controller 2140 can transmit the sensing data to the gateway 2000 without performing an additional process. In this case, the transmission period of the sensing data provided from the controller 2140 may have a default value.

Thereafter, if the resource utilization rate of the gateway 2000 exceeds a predetermined threshold, the controller 2140 may receive information about the data transmission rule corresponding to the resource utilization rate from the gateway 2000. The data transmission rule may be a rule regarding how the gateway 2000 receives the sensing data from which external element 1000 according to the resource utilization rate of the gateway 2000. The data transmission rules may include rules regarding, for example, the external component 1000 to be used to provide the service, the external component 1000 to be suspended, the data providing method of the sensing data, the data transmission period of the sensing data, the data transmission volume, And scheduled transmission of sensing data.

In addition, the controller 2140 may provide the sensing data to the gateway 2000 according to the data transmission rule. For example, the controller 2140 may be scheduled to transmit the average value of the sensing data to the gateway 2000 at a predetermined time. In addition, for example, the controller 2140 may transmit the sensing data to the gateway 2000 after dividing the sensing data, and may change the data transmission period. In addition, the controller 2140 may combine the sensing data and transmit the combined sensing data to the gateway 2000. In addition, the controller 2140 may suspend the transmission of the sensing data.

Thereafter, when the resource utilization rate of the gateway 2000 is reduced to a predetermined threshold value or lower than the threshold value, the controller 2140 may transmit the sensing data to the gateway 2000 according to the default transmission rule.

The gateway 2000 can control at least one external element 1000, and can include a communicator that receives sensing data from the external element 1000, and a controller that determines the processing cycle of the sensing data based on at least one selected from: The resource utilization rate of the gateway 2000 for processing the sensing data, the status information of the external component 1000, and the number of external components 1000.

In addition, the external element 1000 may further include a user input unit (not shown in the figure), an output unit (not shown in the figure), and a memory (not shown in the figure), but it is not limited thereto.

22 is a diagram showing a gateway 2000 receiving sensing data from a plurality of external elements 1000 to change the sense transmitted from the plurality of external elements 1000 when the resource utilization rate of the gateway 2000 changes according to an exemplary embodiment Flow chart of the method for measuring the processing cycle of data.

Referring to FIG. 22, the external device 1000 may transmit the sensing data to the gateway 2000. The gateway 2000 receives the sensing data from the external device 1000 (operation S2201). The gateway 2000 determines whether the resource utilization rate of the gateway 2000 is less than a critical value (operation S2203), and if the resource utilization rate of the gateway 2000 is less than the critical value, the sensing data is processed in the first cycle (S2205); and If the resource utilization rate is greater than the critical value, the sensing data is processed in the second cycle (S2207). That is, the gateway 2000 may change the processing cycle of the sensing data based on the resource utilization rate of the gateway 2000.

For example, a temperature sensor as an external element 1000 may be connected to the gateway 2000, and the temperature sensor transmits the sensed temperature data to the gateway 2000 once per second. Gateway 2000 can be used in the resources of Gateway 2000 When the rate is equal to or less than the critical value of 70%, the temperature data is processed in a second cycle. If the resource utilization rate is greater than 90% of the critical value, the gateway 2000 may change the processing cycle for processing temperature data to every two seconds.

When the resource utilization rate of the gateway 2000 is greater than the critical value, the gateway 2000 may request the temperature sensor to change the data transmission period. For example, when the resource utilization rate of the gateway 2000 is equal to or less than the critical value of 70%, the gateway 2000 may request the temperature sensor to transmit the temperature data to the gateway 2000 once per second. In addition, for example, if the resource utilization rate of the gateway 2000 is greater than the critical value by 90%, the gateway 2000 may request the temperature sensor to send the temperature data to the gateway 2000 every two seconds.

In addition, if the resource utilization rate of the gateway 2000 is greater than the critical value, the gateway 2000 can only receive temperature data from the temperature sensor once per second, but does not process the temperature data.

In addition, the gateway 2000 may determine the period of receiving the sensing data from the external element 1000 based on the resource utilization rate of the gateway 2000. If the resource utilization rate is less than the critical value, the gateway 2000 can receive the sensing data from the external device 1000 in the first cycle, and if the resource utilization rate is greater than the critical value, the gateway 2000 can receive the sensing data from the external device 1000 in the second cycle Test data. For example, when the resource utilization rate of the gateway 2000 is equal to or less than the critical value of 70%, the gateway 2000 can receive sensing data from the external device 1000 once per second, and when the resources of the gateway 2000 When the utilization rate is greater than 90% of the critical value, the gateway 2000 can receive the sensing data from the external device 1000 once every two seconds.

23 is a method of changing the processing cycle of the sensing data transmitted from the plurality of external elements 1000 when the gateway 2000 receiving the sensing data from the plurality of external elements 1000 is being repaired according to an exemplary embodiment flow chart.

The situation where the gateway 2000 is being repaired may include a situation where the gateway 2000 changes or updates software related to the operation of the gateway 2000. For example, the case where the gateway 2000 is being repaired may include the case where the driver software of the gateway 2000 is updated, the case where the application software installed on the gateway 2000 is updated, and the update is installed on the gateway 2000 The situation of the operating system, but not limited to this.

Referring to FIG. 23, the external device 1000 can transmit the sensing data to the gateway 2000. The gateway 2000 can receive sensing data from the external device 1000 (operation S2301). The gateway 2000 judges whether the gateway 2000 is being repaired (operation S2303). If the gateway 2000 is being repaired, the gateway 2000 processes the sensing data in the first cycle (S2305); and if the gateway 2000 is not being repaired, the gateway 2000 can process the sensing data in the second cycle (S2307). That is, the gateway 2000 may change the processing cycle of the sensing data based on whether the gateway 2000 is being repaired.

For example, a temperature sensor as an external element 1000 may be connected to the gateway 2000, and the temperature sensor may transmit temperature data to the gateway 2000 once per second. The gateway 2000 can process temperature data once per second when the software is not being updated. While the software is being updated, the gateway 2000 can process the temperature data every two seconds after changing the processing cycle.

When the software is being updated, the gateway 2000 may request the temperature sensor to change the data transmission period. For example, the gateway 2000 is not updating the software period In the meantime, the gateway 2000 can control the temperature sensor to transmit the temperature data to the gateway 2000 once per second. While the gateway 2000 is updating the software, the gateway 2000 may request the temperature sensor to send temperature data every two seconds.

In addition, during the software update, the gateway 2000 may only receive temperature data from the temperature sensor once per second, but may not process the temperature data.

24 is a processing cycle for the gateway 2000 to receive sensing data from a plurality of external elements 1000 to change the sensing data transmitted from the plurality of external elements 1000 according to the number of external elements 1000 according to an exemplary embodiment Flowchart of the method.

Referring to FIG. 24, the external device 1000 may transmit the sensing data to the gateway 2000. The gateway 2000 can receive sensing data from the external device 1000 (S2401). The gateway 2000 judges whether the number of external components 1000 is smaller than the set value (S2403). If the number of external components 1000 is smaller than the set value, the gateway 2000 processes the sensing data in the first cycle (S2405); and if the number of external components 1000 is larger than the set value, the gateway 2000 can process the sensing in the second cycle Information (S2407). That is, the gateway 2000 can change the processing cycle of the sensing data based on the number of external components 1000.

For example, if the set value is 10 and ten or less than ten external components 1000 are connected to the gateway 2000, the gateway 2000 can process the sensing data transmitted from the external component 1000 once per second. If fifteen external components 1000 are connected to the gateway 2000, the gateway 2000 can process the sensing data transmitted from the external component 1000 once every two seconds.

In addition, if the number of external components 1000 greater than the set value is connected to the gateway Device 2000, the gateway 2000 may request the external component 1000 to change the data transmission period. For example, if seven (ie, less than a set value) external components 1000 are connected to the gateway 2000, the gateway 2000 may request the external component 1000 to transmit the sensing data to the gateway 2000 once per second. If fifteen (ie, greater than a set value) external components 1000 are connected to the gateway 2000, the gateway 2000 may request the temperature sensor to transmit the sensing data to the gateway 2000 every two seconds.

In addition, if fifteen external components 1000 whose number is greater than the set value are connected to the gateway 2000, the gateway 2000 may receive the sensing data only once per second, but may not process the sensing data.

In addition, the gateway 2000 may determine the period of receiving sensing data from the external element 1000 based on the number of the external elements 1000. When seven external components 1000 are connected to the gateway 2000, the gateway 2000 can receive sensing data from the external component 1000 in the first cycle, and when fifteen external components 1000 are connected to the gateway 2000, the gateway 2000 can receive the sensing data from the external device 1000 in the second cycle. For example, when the number of external components 1000 connected to the gateway 2000 is seven, the gateway 2000 can receive sensing data from the external components 1000 once per second, and when connected to the external of the gateway 2000 When the number of the components 1000 is fifteen, the gateway 2000 can receive sensing data from the external components 1000 once every two seconds.

FIG. 25 is a method for causing the gateway 2000 to receive sensing data from a plurality of external elements 1000 to change the sense from the plurality of external elements 1000 according to an exemplary embodiment according to the state of the external elements 1000 (for example, remaining battery power) Flow chart of the method for measuring the processing cycle of data.

Referring to FIG. 25, the external device 1000 may transmit the sensing data to the gateway 2000. The gateway 2000 can receive sensing data from the external device 1000 (S2501). The gateway 2000 judges whether the remaining battery capacity of each of the external components 1000 is greater than a critical value (S2503). In addition, if the remaining battery capacity of each external device 1000 is greater than the threshold, the gateway 2000 processes the sensing data in the first cycle (S2505); and if the remaining battery capacity of each external device 1000 is less than the threshold Value, the gateway 2000 can process the sensing data in the second cycle (S2507). That is, the gateway 2000 may change the processing cycle of the sensing data based on the state of the external device 1000 (for example, the remaining battery power in the external device 1000). In this case, the gateway 2000 may receive information about the remaining battery capacity of the external device 1000 from the external device 1000. For example, the gateway 2000 may receive information about the remaining capacity of the battery in the external device 1000 from the external device 1000 whenever an event occurs or at a predetermined period. The gateway 2000 can receive the status information of the external component 1000 (for example, information indicating the remaining battery power, information indicating resource utilization, and information indicating network status) while receiving sensing data from the external component 1000.

When the remaining battery capacity of the external device 1000 is greater than the critical value, the external device 1000 transmits the sensing data to the gateway 2000 in the first cycle, and the gateway 2000 can process the sensing data in the first cycle. When the remaining battery capacity of the external device 1000 is less than the critical value, the external device 1000 can transmit the sensing data to the gateway 2000 in the second cycle, and the gateway 2000 can process the sensing data in the second cycle.

For example, if the remaining battery capacity of the external device 1000 is 80%, the external device 1000 can send the sensing data to the gateway 2000 once per second, and The gateway 2000 can process the sensing data transmitted from the external device 1000 once per second. If the remaining battery capacity of the external device 1000 is 20%, the external device 1000 transmits the sensing data to the gateway 2000 every two seconds, and the gateway 2000 can process the transmission from the external device 1000 once every two seconds Sensory data.

In addition, when the remaining battery capacity of the external device 1000 is less than the critical value, the gateway 2000 may request the external device 1000 to change the data transmission period. For example, when the critical value is 30% and the remaining battery capacity of the external device 1000 is 80% greater than the critical value, the external device 1000 can transmit the sensing data to the gateway 2000 once per second. When the remaining battery capacity of the external device 1000 is 20% smaller than the critical value, the gateway 2000 may request the external device 1000 to transmit sensing data once every two seconds.

In addition, if the remaining battery capacity of the external device 1000 is 20% smaller than the critical value, the gateway 2000 may receive the sensing data from the external device 1000 once per second, but the sensing data may not be processed.

In addition, the gateway 2000 may determine a period for receiving sensing data from the external device 1000 based on the remaining battery capacity in the external device 1000. If the remaining battery capacity of the external device 1000 is greater than the threshold, the gateway 2000 can receive sensing data from the external device 1000 in the first cycle, and if the remaining battery capacity of the external device 1000 is less than the threshold, the gateway 2000 The sensing data can be received from the external device 1000 in the second cycle. For example, if the threshold is 30% and the remaining battery capacity of the external device 1000 is 80%, the gateway 2000 can receive sensing data from the external device 1000 once per second, and if the battery in the external device 1000 The remaining power is 20%, the gateway 2000 can receive the sensing data from the external device 1000 once every two seconds.
