6 is a view for explaining an indoor environment in which a home gateway device according to an embodiment is provided.

The home gateway device 200 supports the communication between the collecting device 100 and the sensor module 150 and the external server 300 and means a device capable of interlocking with various object Internet devices existing in the room through the home network do.

Here, the object Internet device refers to a device through which various devices exist in daily life, and can connect to the home network through the built-in communication module and exchange data. For example, the object Internet appliance is not limited to household appliances such as a refrigerator, an air conditioner, a display device, a cleaning robot, a lighting device, a wine refrigerator, a washing machine, a desk top and the like as well as a wearable user terminal such as a smart phone, .

Herein, the home network refers to a network that provides a path through which data can be exchanged with all the Internet devices in the room while providing a path for connection with an external Internet network. The home network may be managed by the home gateway device 200 in an integrated manner.

On the other hand, the home gateway device 200 may be separately provided indoors or outdoors. The home gateway apparatus 200 described below may be one of a separately provided apparatus or a destination Internet appliance.

For example, the home gateway apparatus 200 may be separately provided as shown in FIG. As another example, any one of the object Internet devices may replace the home gateway device 200. 6, any one of the Internet devices such as the air conditioner T1, the display device T2, the portable terminal T3, and the cleaning robot T4 may be operated as the home gateway device 200 There is no restriction, such as can be done.

In other words, the home gateway device 200 includes a communication module capable of communicating with an external device, and includes any electronic device including a processor and capable of various arithmetic processing. Hereinafter, the internal configuration of the home gateway apparatus 200 will be described.

FIGS. 7 and 8 are views showing a control block diagram of a home gateway apparatus according to another embodiment. FIG. 9A schematically shows an indoor environment in which parameters such as gas, electricity, And FIG. 9B is a view schematically showing an indoor environment in which a refrigerator equipped with an opening / closing detection sensor according to an embodiment is installed. Hereinafter, the description will be described together to prevent duplication of description.

Referring to FIG. 7, the home gateway apparatus 200 may include a gateway communication module 210 for supporting communication with an external device via a wired communication network or a wireless communication network, dwelling status information, and usage information, A storage unit 240 for storing control data for controlling the overall operation of the home gateway device 200 and a control unit for controlling the overall operation of the home gateway device 200 230).

Here, the internal structure of the home gateway apparatus 200 is not limited to that shown in FIG. Referring to FIG. 8, the home gateway apparatus 200 may not include the determination unit 220. At this time, all or a part of the operations performed by the determination unit 220 and the control unit 230 may be performed in the external server 300. [ A detailed description thereof will be described later. Hereinafter, it will be assumed that the home gateway apparatus 200 includes the determination unit 220. [

At least one of the gateway communication module 210, the determination unit 220, the control unit 230 and the storage unit 240 is integrated into a system on chip (SOC) built in the home gateway device 200 It is possible. However, since there is not only one system-on-chip included in the home gateway apparatus 200, it is not limited to being integrated into one system-on-chip.

The gateway communication module 210 is a module that supports at least one of a wired communication method and a wireless communication method, such as the collecting device communication module 150 described above. It is omitted.

For example, the gateway communication module 210 may receive usage-by-parameter information from the collection device communication module 150 and may receive the residence status information from the sensor module 160. Also, the gateway communication module 210 may transmit at least one of the received usage-by-parameter information and the residence status information to the external server 300. As described later, the gateway communication module 210 can transmit to the external server 300 the information on the average usage information for each period derived based on the usage information and the information on the result of the specific situation determination, Weather information, and the like.

In addition, as will be described later, when the external server 300 determines a specific situation and decides a countermeasure, the gateway communication module 210 receives from the external server 300 information on the result of the specific situation determination, The gateway communication module 210 can exchange various data with an external device according to a subject performing a specific situation determination process and a countermeasure determination process such as receiving information from the external device. Hereinafter, the determination unit 220 will be described.

The determination unit 220 can determine whether a specific situation has occurred in the room. Here, the specific situation includes various situations that do not occur when a health problem of a member residing in a room is generated, as well as when a malfunction of an indoor device, intrusion of a thief, or the like occurs normally.

The determination unit 220 may determine whether a specific situation occurs in the room based on various information. First, the determination unit 220 may determine whether a specific situation occurs based on the dwelling state information obtained through the sensor module 170. [

Table 1 below roughly describes a process for determining a specific situation using the dwelling status information.

Access sensor Motion detection sensor Judge occurrence of specific situation and determine cause of occurrence ON ON A comparison between real-time usage information and average usage information during the period of residence ON OFF It is judged that a specific situation occurred because there is no movement of members OFF ON Intrusion occurs at a place other than a door, and a specific situation occurs. OFF OFF A comparison between real-time usage information and average usage information during non-residency period

Referring to Table 1, when the movement of the member is not detected for a predetermined time or longer (motion sensor is OFF) even though the member is living in the room through the dwelling state information (entrance sensor ON) It can be judged that a situation has occurred. At this time, when the member is residing indoors, the determination unit 220 may not apply the above-described specific situation determination process to the night time zone in which the motion does not mainly occur. In particular, the judging unit 220 according to the embodiment applies the above-described specific situation judgment process to the assumption that a safety net is required such as a single-family home, a juvenile home or a grandchild living with a grandparent living on a basis of the member information , And a social safety net that can guarantee the safety of the stratum that needs help.

On the other hand, when the amount of indoor use differs from the average usage amount, there is a high probability that a specific situation occurs in the room. Accordingly, the determination unit 220 can determine a specific situation by combining the comparison between the residence status information, the real-time usage information, and the average usage information for each period as shown in Table 1. [

Here, the average usage information for each period refers to information derived from the average usage amount and usage pattern for each period by using usage information collected during a certain period such as quarter, month, day, and time. The average usage information for each period may be derived by the determination unit 220 or may be derived by the external server 300.

9, various electronic devices such as an air conditioner T1 and a display device T2 may be provided in the room. In addition, a gas range G, a water pipe W, and the like may be provided. Therefore, average usage information for each period can be derived for each parameter such as electricity, gas, water, and the like.

In addition, the average usage information for the period can be derived separately when the member is resident and when the user is not resident. The amount of usage may change depending on whether the member is living in the room or not. Therefore, in order to more accurately determine whether a specific situation is based on the real-time use information, it is required to grasp whether or not the member is living in the room.

Accordingly, the determination unit 220 determines whether the member is resident using the residence status information acquired through the sensor module 150, acquires average usage information for the period when the member is resident and when the resident is not resident . Hereinafter, for the sake of convenience, the average usage information for the period when the user is resident is referred to as first average usage information for each period, and the average usage information for each period when the user is not resident is referred to as the second average usage information for each period. However, when it is not necessary to distinguish between the first average usage information and the second average usage information for each period, it is simply referred to as average usage information for each period.

The determination unit 220 may select one of the first average usage information for each period and the second average usage information for each period according to whether the member is resident, and compare the selected one with the real-time usage information to determine a specific situation. That is, when the real-time usage information is collected, the determination unit 220 performs a comparison process with either one of the first average usage information for each period and the second average usage information for each period, It is possible to improve the accuracy of the specific situation judgment.

For example, the determination unit 220 compares the real-time usage information with any one of the first average usage information for each period or the second average usage information for each period to determine a real-time usage amount of at least one parameter among electricity, It is possible to judge whether or not a situation that can not be regarded as a normal state beyond the threshold value of the average usage amount of the comparison target period, that is, whether a specific situation has occurred.

Here, the comparison target period can be set in various ways such as year, quarter, month, day, and time. In one embodiment, the determination unit 220 may set the branch according to various methods. For example, the judging unit 220 divides the year into four quarters and divides the average usage information for each quarter into January-March, April-June, July-September, and October-December Can be obtained. Alternatively, the judging unit 220 may divide into December-February, March-May, June-August, and September-November to reflect seasonal use characteristics.

At this time, the determination unit 220 may select only one comparison target period, that is, compare only average usage information and real-time usage information for one period. However, in order to secure reliability, the determination unit 220 selects a plurality of comparison target periods, It is also possible to compare the average usage information and the real-time usage information in the target period. Accordingly, the determination unit 220 may determine whether a specific situation occurs based on whether the real-time use information is out of the threshold of the average usage information in a plurality of comparison objects.

For example, the determination unit 220 may select the branch and month as the comparison target period, and compare the real-time usage information with the quarterly average usage information, the real-time usage information, and the monthly average usage information.

In one embodiment, the determination unit 220 may compare the real-time use information of February 5, 2015 with the average usage information of the first quarter of 2014 to determine whether or not the preset threshold is exceeded. As a specific example, the determination unit 220 may determine whether the real-time usage information of February 5, 2015 is within the range of 10% from the average usage information of the first quarter of 2014. At this time, the judging unit 220 stores the electricity usage information, the water usage information and the gas usage information of February 5, 2015, the average electricity usage information, the average water usage information, and the average gas usage information of the first quarter of 2014 By comparison, it can be determined whether the real time usage information for February 5, 2015 is within the 10% range from the average usage information for the first quarter of 2014.

If it is determined that the first threshold is exceeded, the determination unit 220 compares the real-time usage information of February 5, 2015 with the average usage information of February 5, 2014, and determines whether or not the second threshold is exceeded Can be determined. Accordingly, if it is determined that the real-time use information of February 5, 2015 is out of the first threshold value and the second threshold value, the determination unit 220 can determine that a specific situation has occurred. In addition, the determination unit 220 can identify the cause determined as a specific situation using other information, and increase or decrease the accuracy of the determination of the specific situation by reaffirming or correcting the determination result regarding the specific situation. .

On the other hand, the determination unit 220 is not limited to the comparison of usage information regarding all parameters of electricity, water, and gas. The determination unit 220 may compare at least one parameter with usage information about at least one selected parameter and average usage information per period to determine that the real time usage amount of the selected parameter is out of the threshold value of the average usage amount of the comparison target period It can be judged that the surface condition is satisfied.

For example, the determination unit 220 may use any weather information to select any one parameter having an average usage amount in the corresponding season, compare only the usage information of the selected parameter with the usage information of the selected season, It can be judged that the condition is satisfied if the real-time usage amount is changed by 10% or more from the average usage amount of the comparison target period.

As another example, the determination unit 200 may select two parameters and determine that the condition is satisfied if the usage information about the selected two parameters has changed by 10% or more from the average usage information. When determining a specific situation based on usage information on a plurality of parameters, the determination unit 220 can set a priority order among parameters to be compared using weather information. The parameters that are mainly consumed indoors are different depending on the season. For example, summer consumes more electricity than gas. In winter, more gas is consumed than in the capital.

In one embodiment, in the case of summer, the determination unit 220 may select electricity and water as comparison target parameters, and set priorities in order of electricity and water. At this time, if the real-time electricity use amount is within the threshold value, the determination unit 220 may not perform the comparison process of the real time water usage amount. However, if the real-time electricity usage amount is out of the threshold, the determination unit 220 may compare the real water usage amount with the average water usage amount of the comparison target period to determine whether or not the actual usage amount is out of the threshold. That is, the judging unit 220 according to the embodiment not only prevents the overload of the calculation by comparing the usage information about the parameter judged to be high in use, reflecting the seasonal characteristics, It can be judged.

On the other hand, the average usage information per period can be obtained only when usage information is collected for a certain period of time. Therefore, the usage comparison process can be performed using the member information or usage information input by the user through the input interface of the home gateway device 200 before usage information is collected for a predetermined period of time. Alternatively, the determination unit 220 may receive the member information or usage information from the external device through the gateway communication module 210, and may perform the usage amount comparison process.

Here, the member information is information on the member residing in the home, and may include various information such as the number of members, the age of the members, characteristics of the members, and the like. In addition, the member information may include information on a defective assumption, only a living elderly person living alone, a member having a medical history, or a family member who is currently suffering from a diseased member.

The determination unit 220 derives the average usage information for each period by using the number of residents and age groups of the members using the member information, compares the average usage information with the real-time usage information, It can be judged. The data related to the method of deriving the average usage information for each period based on the member information may be implemented in an algorithm and a program form and stored in the storage unit 240. The determination unit 220 may store Data can be used to derive average usage information for each period.

On the other hand, when it is judged that the specific situation is arithmetic only based on the use information, the accuracy of the specific situation judgment may be lowered. Accordingly, the judging unit 220 according to the embodiment confirms the cause judged to be a specific situation by using various information that helps to grasp the situation of the actual residence area, and reaffirms whether the specific situation is correct based on the confirmation result can do. In other words, the determination unit 220 according to the embodiment can increase or decrease the accuracy of the specific situation determination by checking or correcting the determination result regarding the specific situation using various information.

According to one embodiment, the determination unit 220 may compute the temperature difference between indoor / outdoor by comparing the temperature information measured through the temperature sensor provided in the room with the weather information received from the external network. Accordingly, the determination unit 220 can identify the cause of the specific situation based on the temperature difference between indoor / outdoor and the presence or absence of the member.

For example, if the real-time usage is less than 90% of the average usage and the member is living and the summer room temperature is more than 5 degrees above the outdoor temperature, there is a high probability that the occupant's health is problematic due to the high temperature in the room . Accordingly, the determination unit 220 may determine that a specific situation has occurred, and may perform a corresponding action according to the specific situation.

As another example, if the real-time electricity consumption is lower than a predetermined threshold value of the average electricity consumption in the comparison period, that is, the real-time electricity consumption is less than 90% of the average electricity consumption in the comparison period, If the temperature is higher than the outdoor temperature by more than 5 degrees, it is more likely that the indoor devices are turned off (OFF) rather than the specific situation. Therefore, the determination unit 220 can determine that the determination result is not a specific situation and corrects the determination result, and does not perform any countermeasure.

As another example, when the real-time usage amount is higher than a preset threshold value of the average usage amount, that is, when the real-time electricity usage amount is 110% or more of the average electricity usage amount in the comparison target period, The reason why the high temperature is maintained even when the indoor device is in operation is that there is a high probability that an abnormality has occurred in the indoor device. Accordingly, the determination unit 220 may determine that the abnormal condition such as a malfunction of the indoor apparatus corresponds to a specific situation, and decide to perform a countermeasure according to the identified specific situation.

In other words, the determination unit 220 according to the embodiment not only analyzes a specific situation based on usage information, but also analyzes the cause determined to be a specific situation using other information, By judging again, it is possible to increase the accuracy of the specific situation judgment and to decide an appropriate countermeasure according to the cause of the occurrence.

In addition, the judging unit 220 according to the embodiment can detect the cause of the occurrence of the specific situation by using the opening / closing sensor provided in the indoor device, check whether the judgment result on the specific situation is correct, The accuracy of the specific situation judgment can be enhanced.

For example, when the member is in a residence and the real-time electricity usage is larger than the electricity usage in the comparison period, the determination unit 220 checks the abnormal state of the indoor device using the output value of the opening / closing sensor, The cause of the occurrence can be grasped.

For example, as shown in FIG. 9B, the opening / closing detection sensor 190 may be provided on one side of the refrigerator door to detect opening / closing of the refrigerator door. Accordingly, the determination unit 220 can determine whether the refrigerator door has been opened for a predetermined time or longer by using the output value received from the opening / closing detection sensor 190, so that the electricity consumption is high. If it is determined that the refrigerator door has been opened for a predetermined time or longer, the determination unit 220 may determine that the cause of the occurrence of the specific condition is the opening of the refrigerator door, and decide to take countermeasures according to the specific situation.

As another example, when the amount of electricity used is less than the amount of electricity used in the comparison period even though the member is resident, the determination unit 220 uses the output value of the opening / closing sensor 190 to determine the cause of the occurrence of the specific condition I never do that. At this time, the determination unit 220 may determine that the cause of the occurrence of the specific situation is a health cause of the member, and may decide to perform the countermeasure according to the specific situation.

In other words, the determination unit 220 according to the embodiment does not determine the specific situation by merely performing the arithmetic comparison, but rather grasps the reason why the real-time usage amount per parameter is larger or smaller than the usage amount of the comparison target period by using other information, Appropriate response measures can be decided.

11 and 12 are diagrams for explaining an operation flow of a safety net management system for determining whether a specific situation occurs and at least one of specific events through at least one of a dwelling state information of a member according to different embodiments and a usage amount analysis to be.

Referring to FIG. 11, the collecting apparatus 100 may transmit parameter-specific usage information to the home gateway apparatus 200 (1300). The collecting apparatus 100 may include a device capable of measuring the usage amount of various parameters consumed in the room such as electricity, gas, water, and the like, and a communication module capable of transmitting the measured usage amount. Accordingly, the collecting apparatus 100 can periodically collect usage information according to a preset period and deliver it.

Also, the sensor module 160 may collect the residence status information and transmit the collected residence status information to the home gateway apparatus 200 (1310). Here, the dwelling status information is information on the dwelling status of the member, and may include information on whether the user is resident or non-dwelling, as well as information on the movement of the member in the case of residence. In addition, the residence status information may include information as to whether or not the entry of a member or another user corresponds to a normal access.

For example, when a motion of a specific person is detected through a motion sensor or a camera module, the sensor module 160 determines whether the output value of the access sensor has been changed before the motion is detected, It is possible to obtain information as to whether or not it has been done, that is, whether it corresponds to a normal access.

Then, the home gateway apparatus 200 may determine whether the indoor situation corresponds to a specific situation using the dwelling state information and the usage information for each parameter (1320). Here, the home gateway device 200 compares the usage information for each parameter received in real time with any one of the average usage information for each period stored in the storage unit of the home gateway device 200 and the average usage information for each period stored in the external server 300 , It is possible to determine whether or not a specific situation has occurred according to whether or not the predetermined threshold is exceeded.

At this time, the home gateway apparatus 200 can select the average usage information to be compared among the first average usage information or the second average usage information for each period stored in the home gateway apparatus 200 or the external server 300 according to the dwelling state information . The usage amount of each parameter varies depending on whether the member is in the residence. Therefore, the home gateway device 200 according to the embodiment classifies and calculates the average usage information for each period according to the presence or absence of the member, and then calculates average usage information It is possible to increase the determination accuracy of the specific situation.

At this time, the home gateway apparatus 200 compares only the usage amount of one parameter among the parameters and determines whether or not the difference exceeds a preset threshold value, or selects two or more parameters, and if the usage amounts of the selected parameters all exceed a predetermined threshold value It may be judged that it corresponds to a specific situation. At this time, the selection of the parameter to be compared and the selection of the number of parameters may be changed according to the season or the weather, or may be changed according to the setting of the user

In addition, the home gateway device 200 has no limitation, for example, setting only one comparison target period or setting two or more comparison target periods, and then comparing the average usage information and the real-time usage information in the set comparison period.

If it is determined that the real-time use information is out of the preset threshold value of the average usage information of the comparison period, the home gateway device 200 firstly determines that the specific situation corresponds to the specific use situation, And the opening / closing information may be additionally used. Here, the weather information includes information about the outdoor temperature and the season received from the web through the communication network, and the room temperature obtained through the temperature sensor. The opening / closing information includes information on an output value of the opening / closing sensor.

The home gateway device 200 checks once again whether it can be seen as a specific situation such as health of a member, abnormality of an indoor device, malfunction, or the like by grasping what is the cause of the usage amount of at least one parameter out of the threshold.

For example, when the member is in a residence and the amount of electricity used exceeds the preset threshold value, the home gateway device 200 uses the output value of the opening / closing sensor provided in the refrigerator to open the refrigerator door It is possible to determine whether a specific situation has occurred. If it is determined that the refrigerator door has been opened for a predetermined time or more, the home gateway device 200 can confirm that the specific situation has occurred and determine the corresponding countermeasure.

The home gateway device 200 receives the outdoor temperature information and the seasonal information from the web server and receives the outdoor temperature information and the seasonal information from the web server, Lt; / RTI > The home gateway device 200 can calculate the temperature difference between indoor / outdoor using the above-described information, and can confirm whether a specific situation has occurred by using the calculated temperature difference of indoor / outdoor.

Meanwhile, the home gateway device 200 according to the embodiment can not only use the output values of the opening / closing sensor, the temperature sensor, and the like in all cases, but can also determine the cause of the occurrence of the specific situation by using the output value only under predetermined conditions .

For example, if a member is not resident indoors, the temperature in the room is below 5 degrees Celsius in summer, and the real-time electricity usage is less than 90% of the average electricity consumption during the comparison period, Otherwise, there is a low probability that a malfunction or abnormality of an indoor device has occurred. Accordingly, the home gateway apparatus 200 can correct the determination result that the abnormal state is not a specific situation without checking the output value of the autonomic nervous system sensor. That is, the home gateway device 200 according to the embodiment does not judge a specific situation by comparing only the usage amount, but can confirm whether or not it can be viewed as a specific situation by using weather information, open / close information, .

Table 2 below outlines the process of identifying the cause of a specific situation based on the indoor / outdoor temperature difference and confirming or correcting the occurrence of a specific situation.

In Table 2, the parameter to be used for the usage comparison may be at least one or more, and may be different depending on the season. For example, in summer, the cause and reaffirmation of a specific situation can be performed on the basis of electricity consumption, and there is no limitation such that the cause and reaffirmation of a specific situation can be performed based on the amount of gas used in winter.

In addition, Table 3 outlines the process of identifying the cause of the specific situation through the dwelling state information of the member and the output value of the opening / closing sensor, and re-confirming whether a specific situation has occurred.
