Description

Protection layer living condition monitoring device and method {APPARATUS AND METHOD FOR MONITORING LIVING SITUATION OF RECIPIENT OF LIVELIHOOD PROGRAM}

The present invention relates to a protective layer living condition monitoring device and method, and more particularly to a protective layer living condition monitoring device and method for monitoring the living state of the protective layer based on the power consumption.

According to the data released by the Organization for Economic Cooperation (OECD), in 2030, Korea predicts that the proportion of the elderly aged 65 or over will be 24.3%, the fourth-largest elderly society.

As a result, many companies and governments are providing benefits and services to the minority, even though they are providing volunteer services and various services for the social protection class who are socially and economically disadvantaged, such as the elderly living alone, the demented elderly, the boys and girls and the disabled. There are practical difficulties in using it.

In addition, the economic population that can support the protection layer is decreasing every year, and the government's support policy due to the increase in the protection layer is limited due to lack of budget.

Therefore, the field of protection layer safety confirmation technology using electric power consumption that can be used without additional installation or additionally various sensors has been developed, and active research has been conducted since the late 2000s.

For example, in Korean Patent Laid-Open Publication No. 10-2011-0022171 (name: system and method for monitoring living conditions of elderly people living alone), a threshold value is set for monitoring living conditions of elderly people living alone. Find out. The threshold value used here is set to the sum of the variation amount of the periodic on / off pattern and the variation amount of the random variation pattern. However, since the above threshold is maintained for one day, the accuracy of detecting the user on / off pattern is inferior, and the fluctuating power consumption is classified only by the threshold expressed as the sum of the variation of the periodic on / off pattern and the random variation pattern. How to do this is not clear.

In addition, Korean Patent No. 10-1092734 (name: customer management system and management method using the integrated metering system) to set the reference value of the power consumption using the curve fitting method to detect inactivity. This extracts a plurality of peak points and determines only one peak point having the lowest value among the peak points as the reference value. However, this curve fitting method is easy to identify the pattern by reducing the deviation of the power consumption, but there is a problem that it is difficult to classify the timer-based power consumption or the constant power consumption if the lowest value among the peak points is a reference value.

In addition, although many prior arts use various sensors (fire, entry, operation, emergency, bio, gas, temperature, humidity sensors) in determining the activity / inactivity of the protection layer, the protection layer privacy problem There may be a lot of constraints on installation, and there is a problem that the accuracy of the activity / inactivity judgment is determined according to the number and combination of sensors.

The present invention has been proposed to solve the above-described problems, and to classify the household appliances in use in the protection layer based on the threshold value calculated in real time using the power consumption of the protection layer consumer to determine the inactivity of the protection layer. It is an object of the present invention to provide an apparatus and method for monitoring a protection layer living condition.

It includes a determination unit for determining whether or not.

The calculator sets the current power consumption as a reference value when the initially set threshold value is equal to or greater than the minimum power consumption, and sets the average of four power consumption before the reference value as a comparison value.

The calculation unit resets the reference value to the threshold value if the reference value and the previous three power consumptions are within the error range of the comparison value, respectively, and returns the previous threshold value if the reference value and the previous three power consumptions are outside the error range of the comparison value. Set to the threshold.

The determination unit determines that there is no activity of the protection layer consumer when there is no operation of the user-operated home appliance.

The communication unit further collects sensor detection information and telephone usage of the protection layer consumer.

The determination unit determines that there is no operation of the user of the home appliance, there is no movement of the protection layer on the basis of the sensor detection information, and the inactivity of the protection layer consumer is not generated.

If the current power usage is less than the threshold value, the determination unit determines that the home appliance is always operating. If the current power usage is not within the threshold range, the previous week average value of the same time zone is set as the reference value. If it is less than the reference value is determined as the operation of the timer-based home appliances, if the current power consumption exceeds the reference value is determined as the operation of the user operating home appliances.

The determination unit generates an alarm when the inactivity time of the protection layer consumer is maintained for more than the reference time.

The service provider may further include a service providing unit configured to provide a monitoring result of the protection layer consumer to a subject who has been authenticated in the form of at least one of web, mobile web, phone, email, and SMS.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to facilitate a person skilled in the art to easily carry out the technical idea of the present invention. . In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Hereinafter, a protection layer living state monitoring apparatus according to a first embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 is a view for explaining a protection layer living state monitoring apparatus according to a first embodiment of the present invention, Figure 2 is a block diagram for explaining the configuration of the protection layer living state monitoring apparatus of FIG. 3 is a diagram for describing the communication unit of FIG. 2, and FIG. 4 is a diagram for explaining the calculation unit of FIG. 2.

As shown in FIG. 1, the protection layer living state monitoring device 100 is connected to one or more protection layer consumers 200 and the network 300 to collect strategic usage, and to use the life cycle and safety of the protection layer. Monitor the occurrence of accidents.

To this end, as shown in FIG. 2, the protection layer living state monitoring apparatus 100 includes a communication unit 110, a calculation unit 130, and a determination unit 150.

The communication unit 110 collects power consumption from the electricity meter 220 installed in the protective layer consumer 200. That is, as shown in Figure 3, the communication unit 110 is composed of a PLC communication module 112, the always-operating home appliances 222, user-operated home appliances 224, used in the protection layer customer 200, Collect the power consumption (ie power consumption (kW)) of the timer-based home appliance 226. In this case, the permanent home appliance 222 is a minimal household appliance basically used by the protection layer consumer 200, and has a small amount of change. User-operated home appliances are electronic devices that are turned on / off by a protection layer and have a large change in power consumption. The timer-based home appliance 226 is an electronic device that is periodically turned on and off, such as a refrigerator, but may vary depending on the season, but has a change amount of approximately periodic and constant size. Here, Table 1 below shows an example of home appliances used in the protective layer consumer (200).

The calculation unit 130 calculates a threshold value that is the basis for determining the living state of the protection layer. To this end, the calculator 130 calculates the threshold of the protection layer consumer 200 using the power consumption and threshold calculation algorithm (TCA) collected through the communication unit 110. Here, the threshold calculation algorithm will be described in more detail.

First, the calculator 130 sets the current power consumption of the protection layer consumer 200 collected through the communication unit 110 as a threshold for initialization of the threshold. The calculator 130 sets the current power consumption as a reference value when the initially set threshold value is greater than or equal to the minimum power consumption. In this case, if the threshold value is less than the minimum power consumption, the previously collected power consumption (that is, the power consumption collected 15 minutes ago) is set as the reference value. The calculator 130 calculates an average value of the four power consumptions (that is, the power consumption collected one hour ago) before the preset reference value, and sets it as a comparison value. The calculator 130 determines whether the reference value and the previous three power consumptions (that is, the power consumptions collected up to 45 minutes ago) are within an error range of the comparison value. At this time, the calculator 130 sets the reference value as the current threshold value if the reference value and the previous three power usage amounts are within an error range of the comparison value. The calculator 130 sets the previous threshold as the current threshold when the reference value and the previous three power usage amounts are out of the comparison value error range.

Here, since power data are acquired at 15 minute intervals, the threshold target interval is based on the fact that four data at one time interval should be within a certain range. Since being within a certain range means that it should not respond to minimum power consumption, the current threshold is determined by determining whether four power data within the minimum power consumption range are within the range of the average value, which is changed in real time. For example, FIG. 4 illustrates a threshold calculated based on power consumption measured based on 24 hours a day.

Therefore, the threshold value calculated by the calculating unit 130 is not constant because it is obtained by recalculating in real time (every 15 minutes), but it is a basis for discriminating always-operated home appliances with a small amount of change.

The determination unit 150 determines whether the protection layer consumer 200 is inactive based on the threshold value calculated by the calculation unit 130 and the power consumption collected by the communication unit 110. That is, the determination unit 150 classifies the always-operated home appliance, the timer-based home appliance 226, and the user-operated home appliance 224 based on the threshold value and the power consumption. The determination unit 150 monitors the activity state of each home appliance to determine whether the protection layer consumer 200 is inactive. In this case, the determination unit 150 determines that the protection layer consumer 200 is inactive when power is consumed only in at least one of the permanently operated home appliance 222 and the timer-based home appliance 226. That is, the determination unit 150 determines whether the user-operated home appliance 224 consumes power based on the threshold value and the power consumption, and when there is no power consumption of the user-operated home appliance 224, the protection layer consumer 200. Judging by inactivity.

To this end, the determination unit 150 determines that the home appliance is always operated when the current power usage amount is less than the threshold. The determination unit 150 sets the average value of the previous week in the same time zone as a reference value when the current power usage amount does not exist within an error range of the threshold value. The determination unit 150 determines that the timer-based home appliance 226 operates when the current power usage is less than the reference value, and determines that the user operated home appliance 224 operates when the current power usage exceeds the reference value.

The determination unit 150 determines to be careful if the inactive state of the protection layer lasts for more than 24 hours, and generates an alarm if it determines to be abnormal if the inactive state of the protection layer lasts for more than 48 hours.

At this time, if the reference value and the previous three power use amount is within the error range of the comparison value (S126; YES), the reference value is set to the current threshold value (S127).

The calculator 130 sets the previous threshold as the current threshold when the reference value and the previous three power usage amounts are out of the comparison value error range (S128).

The determination unit 150 determines the inactive state of the protective layer consumer 200 based on the calculated threshold value (S130). That is, the determination unit 150 determines whether the protection layer consumer 200 is inactive based on the threshold value calculated in step S120 and the power consumption collected by the communication unit 110.

At this time, if the current power usage is out of the threshold error range (S133; no), the determination unit 150 sets the average value of the previous week in the same time zone as the reference value (S134). For example, when the current power usage is measured at 2 pm on Monday, the average value of the power consumption collected at 2 pm from the previous Tuesday to Sunday is calculated and set as the reference value.

The determination unit 150 compares the current power consumption with a reference value. At this time, if the current power usage is less than the reference value (S135; Yes), the determination unit 150 determines that the timer-based home appliance 226 of the protection layer consumer 200 is operating (S136).
