For example, a refrigerator, a lighting, a TV, a washing machine, a radio, a vacuum cleaner, and a CCTV.

Hereinafter, the gateway device 100 will be described in detail.

2 is a block diagram of a gateway device according to an embodiment of the present invention. Referring to FIG. 2, the gateway device 100 may include a terminal connection unit 10, a control unit 20, and a wireless communication unit 30.

The terminal connection unit 10 may electrically connect the gateway device 100 and the terminal 200. Accordingly, the gateway device 100, which is supplied power from the terminal 200, can perform necessary operations and can transmit / receive various data by performing wireless communication with the plurality of Internet devices 500.

The wireless communication unit 30 is configured to perform communication with various types of external devices according to various types of communication methods. The wireless communication unit 30 may include various wireless communication modules 31 to 34. Specifically, the first wireless communication module 31 can communicate with the first object Internet device D1 and the second wireless communication module 32 can communicate with the second object Internet device D2. have. In this case, if the first and second Internet devices D1 and D2 use the same communication network 400, one wireless communication module may be used.

Meanwhile, there are various types of wireless communication modules and there are various types of wireless communication modules including a Wi-Fi module, a Bluetooth module, a ZigBee module, a wireless LAN module, a geo-wave module, an NFC module, a 3G (3rd Generation) module, a 3GPP ) Module, a 5G (5th generation) module, an LTE (Long Term Evolution) module, and the like.

Meanwhile, the wireless communication unit 30 can perform communication with the server 300. Accordingly, various search words may be transmitted or received, and search results related to the search words may be received. In addition, the wireless communication unit 30 can directly control the object Internet device by directly communicating with the object Internet device.

2, various external terminals such as a USB port, a High-Definition Multimedia Interface (HDMI), a headset, a mouse, a LAN, and the like, to which a USB connector can be connected are provided in the gateway device 100 And various external input ports for connection.

The control unit 20 can control the operation of each of the plurality of Internet unnecessary devices 500 using the data received through the wireless communication unit 30. [ The control unit 20 will be described in detail below.

3 is a flowchart illustrating a method of controlling a gateway device according to an embodiment of the present invention.

The gateway device 100 transmits a plurality of control signals to the plurality of Internet devices 500 to control the plurality of Internet devices 500 and receives an operation signal from each of the plurality of Internet devices 500 can do. The data transmission / reception with the object Internet device is performed through the respective wireless communication modules as described above. Herein, each of the wireless communication modules consume power according to data transmission / reception. As shown in FIG. 4, the power consumption of the wireless communication module differs according to the type of the wireless communication module. Accordingly, each wireless communication module consumes various levels of power. In some cases, the power consumption exceeded the power consumption set to the gateway device by the operation of two or more wireless communication modules may overload the gateway device. A case in which two or more wireless communication modules operate at the same time is a representative example. Therefore, there is a need to control the operation timing of each of the wireless communication modules 31 to 34. [

Hereinafter, only a case where a plurality of control signals are transmitted from the gateway apparatus 100 to the plurality of Internet apparatuses 500 is described. However, when the gateway apparatus 100 transmits a plurality of operation signals to the plurality of Internet apparatuses 500, The present invention is not limited thereto. However, when the gateway device 100 receives a plurality of operation signals from the plurality of Internet devices 500, the gateway device 100 may be operated regardless of the power consumption of the corresponding wireless communication module upon receipt of the operation signal, It may mean that the power consumption of the corresponding wireless communication module is small enough not to affect its operation upon reception of the signal.

Referring to FIG. 3, the controller 20 may measure the power consumption of each wireless communication module when transmitting a plurality of control signals (S310). Specifically, the gateway device 100 may transmit respective control signals to control the plurality of Internet devices 500. The plurality of control signals are transmitted to the plurality of Internet apparatuses 500 by the respective wireless communication modules. The controller 20 can measure the power consumption of each wireless communication module when each control signal is transmitted.

Thereafter, the controller 20 may compare the measured power consumption with the predetermined power consumption (S320). Specifically, the gateway device 100 may further include a storage unit (not shown), and the power consumption set for the gateway device 100 may be stored in the storage unit (not shown). The predetermined power consumption may mean limited power consumption so that the gateway device 100 is not overloaded. That is, if the measured power consumption is equal to or greater than the predetermined power consumption, the gateway device 100 is in an overload state, and if the measured power consumption is less than the predetermined power consumption, the gateway device 100 may be in a normal state. Here, 'ideal' may be replaced with 'excess', and 'less than' may be replaced with 'less'.

If the measured power consumption is equal to or greater than the predetermined power consumption (S330_N), the control unit 20 can measure a plurality of the power consumption again (S310). If the same result is obtained by measuring the power consumption again, the control unit 20 turns off the operation of the wireless communication module having the predetermined power consumption or more, because the power consumption is exceeded by the operation of only one wireless communication module (turn-off).

Otherwise, if the measured power consumption is less than the predetermined power consumption (S330_Y), the controller 20 may compare the sum of at least two power consumption with predetermined power consumption (S340). For example, the control unit 20 can compare the power consumption of the first wireless communication module 31 and the power consumption of the second wireless communication module 32 with the preset power consumption. Alternatively, the control unit 20 may compare the power consumption of the first wireless communication module 31 with the power consumption of the third wireless communication module 33 and compare the power consumption with the predetermined power consumption. Alternatively, the control unit 20 may sum up the respective power consumption of the first to fourth wireless communication modules 31 to 34 and compare the power consumption with the predetermined power consumption.

If the sum of the power consumption of at least two is less than the predetermined power consumption (S350_Y), the controller 20 can simultaneously transmit the respective control signals generated from the two or more wireless communication modules corresponding to the power consumption (S360) .

Alternatively, when the sum of the power consumption of at least two or more is equal to or greater than the predetermined power consumption (S350_N), the control unit 20 sequentially outputs the respective control signals generated by the two or more wireless communication modules corresponding to the power consumption, (S370).

As described above, according to the present invention, when the sum of two or more power consumption is determined to be within the predetermined power consumption, the respective wireless communication modules corresponding to the two are operated at the same time, whereby the plurality of Internet devices can be controlled quickly and stably .

4 to 8 are various examples of drawings for explaining the operation of the gateway device according to an embodiment of the present invention. Hereinafter, the operation of the gateway device 100 will be described by way of a specific example, and a description of a part overlapping with the above description will be omitted.

4 shows the power consumption levels of the plurality of wireless communication modules with respect to the predetermined power consumption. Referring to FIG. 4, it can be seen that the power consumption of the first to fourth wireless communication modules 31 to 34 is all below the predetermined power consumption level. Therefore, it can be said that there is no problem in operating each wireless communication module for different time periods. Hereinafter, a method for controlling a plurality of object Internet devices 500 quickly and stably by operating a plurality of wireless communication modules at the same time without exceeding a predetermined power consumption level will be described. Hereinafter, the power consumption of the first to fourth wireless communication modules 31 to 34 will be referred to as first to fourth power consumption, respectively. Hereinafter, it is assumed that each of the first to fourth power consumption is within a predetermined power consumption level.

5A shows a case where the sum of the first and second power consumption and the sum of the third and fourth power consumption are both lower than a predetermined power consumption level. That is, the first and second wireless communication modules 31 and 32 may operate simultaneously or the third and fourth wireless communication modules 33 and 34 may operate simultaneously. Here, referring to FIG. 5B and FIG. 5C relating to the transmission time slot of the control signal, it can be seen that a transmission time slot for a plurality of time intervals is allocated. When the assigned transmission time slot arrives, the control signal corresponding to the transmitted transmission time slot can be transmitted. Therefore, since the two transmission time slots are allocated in FIGS. 5 (b) and 5 (c), the first and second wireless communication modules 31 and 32 simultaneously transmit the respective control signals according to one transmission time slot And the third and fourth wireless communication modules 33 and 34 can simultaneously transmit respective control signals according to one transmission time slot.

The first and second wireless communication modules 31 and 32 may operate before the third and fourth wireless communication modules 33 and 34 operate as shown in FIG. 5 (b) Third and fourth wireless communication modules 33 and 34, and a predetermined time interval may be arranged between the transmission time slots. As such, a time interval is placed between each transmission time slot to avoid collisions between each transmission time slot.

In FIG. 6 (a), the sum of the first and fourth power consumption and the sum of the second and third power consumption are both lower than a predetermined power consumption level. That is, the first and fourth wireless communication modules 31 and 34 may operate simultaneously or the second and third wireless communication modules 32 and 33 may operate simultaneously. Therefore, as shown in Figs. 6 (b) and 6 (c) regarding the transmission time slot of the control signal, the first and fourth wireless communication modules 31 and 34 can simultaneously transmit respective control signals, The second and third wireless communication modules 32 and 33 can simultaneously transmit respective control signals. In this case, the first and fourth wireless communication modules 31 and 34 can operate before the operation of the second and third wireless communication modules 32 and 33 as shown in FIG. 6 (b) And may operate after the operation of the second and third wireless communication modules 32 and 33 as well.

7A shows a case where the sum of the first to fourth power consumption is all lower than a predetermined power consumption level. That is, the first to fourth wireless communication modules 31 and 34 may be operated simultaneously. Therefore, as shown in FIG. 7 (b) regarding the transmission time slot of the control signal, the first to fourth wireless communication modules 31 and 34 can simultaneously transmit respective control signals.

8A shows a case where the sum of the second and third power consumption exceeds a predetermined power consumption level. In this case, when the second and third wireless communication modules 32 and 33 operate simultaneously, a failure may occur in these modules due to the power consumption exceeded. Therefore, as shown in FIG. 8 (b) regarding the transmission time slot of the control signal, the first to fourth wireless communication modules 31 and 34 may be sequentially operated. That is, the first to fourth wireless communication modules 31 and 34 can sequentially transmit the respective control signals according to a predetermined priority order.

FIGS. 9 to 13 illustrate various examples of operations of a gateway apparatus according to another embodiment of the present invention, in which priority of transmission of control signals is given according to a weight. FIG. Hereinafter, the description of the parts overlapping with the above description will be omitted.

9 shows results obtained by applying weights (a, b, c, and d) according to the priority of operation to the power consumption levels of the first to fourth wireless communication modules 31 to 34, respectively. The weight of each weight becomes smaller as a, b, c, and d, and the larger the weight, the higher the priority of the wireless communication module. Also, since it is assumed that all the weights are smaller than 1, it can be seen that the result values to which the weights are applied are all below the predetermined power consumption level. In this case, the resultant value may mean a value obtained by multiplying the value of the power consumption by the weight.

In FIG. 10 (a), the sum of the first and second resultant values and the sum of the third and fourth resultant values are both lower than a predetermined power consumption level. That is, the first and second wireless communication modules 31 and 32 may operate simultaneously or the third and fourth wireless communication modules 33 and 34 may operate simultaneously. Therefore, as shown in FIG. 10 (b) regarding the transmission time slot of the control signal, the first and second wireless communication modules 31 and 32 can simultaneously transmit respective control signals, and the third and fourth wireless The communication modules 33 and 34 can simultaneously transmit respective control signals. However, since the weights a and b are high in the weights c and d, it is known that the first and second wireless communication modules 31 and 32 should preferentially operate with respect to the third and fourth wireless communication modules 33 and 34 have. Accordingly, after the first and second wireless communication modules 31 and 32 simultaneously transmit the respective control signals, the third and fourth wireless communication modules 33 and 34 can simultaneously transmit the respective control signals.

11A shows a case where the sum of the first and fourth result values and the sum of the second and third result values are both equal to or lower than a predetermined power consumption level. That is, the first and fourth wireless communication modules 31 and 34 may operate simultaneously or the second and third wireless communication modules 32 and 33 may operate simultaneously. Therefore, as shown in FIG. 11 (b) and FIG. 11 (c) regarding the transmission time slot of the control signal, the first and fourth wireless communication modules 31 and 34 can simultaneously transmit respective control signals, The second and third wireless communication modules 32 and 33 can simultaneously transmit respective control signals. In this case, the first and fourth wireless communication modules 31 and 34 can operate before the second and third wireless communication modules 32 and 33 operate as shown in FIG. 11 (b) And may operate after the operation of the second and third wireless communication modules 32 and 33 as well.

12A shows a case where the sum of the first to fourth result values is equal to or less than a predetermined power consumption level. In other words, it may mean that the first to fourth wireless communication modules 31 to 34 may operate simultaneously. In this case, as shown in FIG. 12 (b) regarding the transmission time slot of the control signal, 4 wireless communication modules 31 to 34 can simultaneously transmit respective control signals. 12 (a), when the sum of the first to fourth result values exceeds the predetermined power consumption level, the first to fourth wireless communication modules 31 to 34 May sequentially transmit the respective control signals.

FIG. 13 shows a case where a time interval is arranged between each transmission time slot. As described above, since any one of the plurality of control signals is transmitted and the other is transmitted after the time interval passes, collision occurring between each transmission time slot can be avoided.

A predetermined time interval may be arranged between each transmission time slot, but a different time interval may be arranged. 13A shows a case in which different time intervals are arranged and time intervals according to the operations of the first to fourth wireless communication modules 31 to 32 are respectively set to first to fourth time intervals G1, G2, G3, G4). In this case, time intervals of a magnitude proportional to the magnitude of the power consumption may be arranged. Therefore, if the magnitude of the power consumption is large (P1> P2> P3> P4) in the order of the first to fourth wireless communication modules 31, 32, 33 and 34, (G1 > G2 > G3 > G4). This is advantageous in that the operation of the gateway device 100 is made less laborious by increasing the downtime between transmission of control signals as the higher power is consumed.

13 (b) shows a case where a plurality of control signals are simultaneously transmitted, which means that the second and third wireless communication modules 32 and 33 operate simultaneously. In this case, since the second and third wireless communication modules 32 and 33 operate simultaneously, time intervals in which the second and third time intervals are added can be arranged.

The present invention described above can be embodied as computer readable codes on a medium on which a program is recorded. A computer readable medium includes any type of recording device in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). The computer may also include a controller 180 of the terminal. The foregoing detailed description, therefore, should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
