Description

SYSTEM AND METHOD FOR DETERMINING EMERGENCY STATE

The present invention relates to an emergency situation determination system and method, and more particularly, to an emergency situation determination system for determining an emergency situation of an elderly person using electricity consumption.

With the development of medical technology and medical technology, the lifespan of human beings is greatly increased, while the number of elderly people living alone is also increasing due to the nuclear family and changes in the times.

Therefore, an increase in the number of senior citizens living alone who do not receive help from their neighbors or family members and safety issues for them are emerging as social problems.

Elderly people living alone are easily exposed to accidents because their bodies are aging, and even minor accidents can cause serious injuries. Also, since they live alone, it is difficult to notify neighbors or emergency personnel of the situation in case of an accident.

As a result, social protection systems for the elderly living alone are increasing. In such a social protection system, the activities of social workers or volunteers are an important part, so the number and labor force are limited. that is impossible.

In particular, the elderly living alone who do not have financial resources cannot use expensive social protection systems such as Silver Town, and are therefore more exposed to various accidents such as fire.

Therefore, there is a need for a system that can inform the elderly living alone about their accident or emergency situation with a simple operation method that is inexpensive enough to not have a financial burden. Based on this, the need for a system that can manage the elderly living alone before an accident is further increased.

As shown in FIG. 1, each of the electrical distributors 51-53 may have the same structure.

As an example, each of the electrical distributors 51-53 includes at least one plug insertion hole 511 , 521 , 531 into which the plug of the electronic product 100 is inserted, the power supply line L1 and the plug insertion hole 511 , 521 , 531 . ) connected to the switching unit [eg, relay] (513, 523, 533), the power consumption sensing unit ( 514, 524, 534).

The warning unit 60 operates under the control of the emergency determination unit 41 of the control unit 40 , and operates when the state of the house is determined to be an emergency.

The warning light unit 60 may include a speaker that outputs a predetermined sound using the audio signal stored in the storage unit 20 and a light emitting unit such as a light emitting diode or a fluorescent lamp.

The light unit 60 is mounted on the outside of the house so that people around can quickly recognize the operation of the light unit 60 from the outside to quickly recognize the emergency state of the house.

Such a light unit 60 may be wirelessly connected to the control module 70 through the communication unit 70 and the one shown in FIG. 1 , and in this case, the light unit 60 communicates with the communication unit 70 (eg , short-distance communication) may be provided with a communication unit.

The communication unit 70 is for communication with an external device such as the manager terminal 80 , and may perform at least one of wired communication and wireless communication.

The communication unit 70 may include at least one of an Internet communication module and a short-range communication module.

The Internet communication module refers to a module for wireless or wired Internet access, and the Internet communication module may be built-in or external to the elderly management system of this example.

The manager terminal 80 receives the operating state of each electric distributor 51-53 of the distribution unit 50 to the control unit 40 through the communication unit 40 and short-distance communication or Internet communication, etc., as previously described, The operation of each electrical distributor 51-53 can be monitored.

Accordingly, the user of the manager terminal 80 can quickly recognize the emergency of the corresponding house and take necessary measures such as visiting the corresponding house.

A manager who is a user of the manager terminal 80 may be a guardian of a resident of the corresponding house or a manager of a public institution, and the manager terminal 80 may be at least one of a smart phone, a notebook computer, or a desktop computer.

However, if necessary, the manager terminal 80 may be omitted in the emergency situation determination system.

Next, with reference to FIGS. 2A and 2B , the operation of the emergency situation determination system having such a structure is as follows.

First, when the power required for the operation of the emergency determination system is supplied and the operation of the emergency determination system starts, the operation of the emergency determination unit 41 of the control unit 40 is also started ( S10 ).

Accordingly, the emergency determination unit 41 of the control unit 40 reads the signal applied from the timer 42 to determine whether the first elapsed time has reached the first set time (S11).

In this case, the first set time is a time for determining the current accumulated electricity consumption, and the elderly management system of this example may determine the current accumulated electricity consumption for each first set time to determine whether an emergency has occurred.

The first set time may be set to a one-day cycle, that is, 24 hours.

Therefore, when it is determined that the first elapsed time has reached the first set time, the emergency determination unit 41 initializes the first elapsed time to '0' (S12) and stores it in the storage unit 20 The current accumulated electricity consumption for the first set time is read (S13).

In this example, the current accumulated electricity consumption is the total amount of electricity consumed during the first set time, and may be the accumulated power consumption or the accumulated current consumption intensity.

The current accumulated electricity consumption is a calculated amount of electricity consumed by accumulating real-time electricity consumption determined using a detection signal applied in real time from each electricity consumption detection unit 514 , 524 , 534 for a first set time, and determining a dangerous state It may be calculated by the unit 41 and stored in the storage unit 20 .

However, as another example, the current accumulated electricity consumption for the first set time can be calculated using a signal applied from a separate electricity meter (not shown) or the accumulated electricity consumption applied from an electricity rate management server (not shown). there is.

For example, the emergency determination unit 41 periodically receives the accumulated electricity consumption through the communication unit 70 from the electricity meter or the electricity rate management server every first set time, and then receives the previously received accumulated electricity consumption and the current By calculating a difference between the received accumulated electricity consumption, the current accumulated electricity consumption for the first set time may be calculated.

As such, when the current accumulated electricity consumption is calculated or confirmed for the first set time, the emergency determination unit 41 subtracts the current accumulated electricity consumption from the previous accumulated electricity consumption that is the previously calculated accumulated electricity consumption, and the previous accumulated consumption A decrease amount of the current accumulated electricity consumption compared to the amount of electricity is calculated (S14).

Then, the emergency determination unit 41 compares the calculated reduction amount with the set reduction amount stored in the storage unit 20 to determine whether the calculated reduction amount is equal to or greater than the set reduction amount (S15). In this case, the set reduction amount is for determining an emergency situation of the corresponding house using the accumulated electricity consumption, and may be set by a guardian or a manager.

The calculated reduction amount is equal to or greater than the set reduction amount, and the emergency determination unit 41 determines the current house electricity use state as an abnormal state and determines the current house state as an emergency state. Accordingly, the emergency determination unit 41 outputs a driving signal to the light unit 60 to drive the light unit 60 .

Accordingly, since the warning light 60 installed outside the house operates a speaker and a warning light to output a warning light together with a warning sound, the operating state of the warning light 60 is known to the outside. Due to the operation of the warning light unit 60, people around the house quickly recognize the emergency situation, and visit the house to check whether an accident has occurred.

At this time, when the warning light unit 60 is wirelessly connected to the control module 40 , the emergency determination unit 41 outputs a driving signal of the warning light unit 60 to the communication unit 70 , and the warning light unit 60 ) operates according to the driving signal applied from the emergency determination unit 41 using the provided communication unit (not shown).

Also, the emergency determination unit 41 may transmit an emergency notification message to the manager terminal 80 using the manager's contact information stored in the storage unit 20 (S17). In this case, the emergency determination unit 41 may transmit the installation address of the corresponding distribution unit 40 stored in the storage unit 20 together with the emergency notification message.

Accordingly, the user who has received the emergency notification message through his/her terminal 80 can quickly visit the house to check the house situation or make a phone call. At this time, as the warning light unit 60 operates outside the house, the manager can quickly find and inspect the house even if it is the first road.

However, if the calculated reduction amount is smaller than the set reduction amount (S15), the emergency determination unit 41 determines that electricity is being consumed in a normal state, and a resident (eg, an elderly person over 70 years old) living in the house It can be judged as a state in which there is no risk to the person's life.

Therefore, when the calculated reduction amount is smaller than the set reduction amount (S15), the emergency determination unit 41 may store the current accumulated electricity consumption calculated in step S14 as the previous accumulated electricity consumption in the storage unit 20 ( S18).

Next, the emergency determination unit 41 may determine whether the second elapsed time has reached the second set time by using the signal applied from the timer 42 ( S110 ).

In this case, the second set time is much shorter than the first set time, and the second set time is a time for determining an emergency situation of a resident living in the house using the total amount of electricity consumed in real time. For example, when the total amount of electricity consumption does not change for the second set time and is constant, the emergency determination unit 41 may determine that the resident is in danger.

When it is determined that the second elapsed time has reached the second set time (S110), the emergency determination unit 41 initializes the second elapsed time to '0' so that the second elapsed time can be counted again. (S111).

Next, the emergency determination unit 41 uses a detection signal applied from the electricity consumption detection units 514, 524, 534 located in each electricity distributor 51-53 to determine the instantaneous total electricity consumption of the distribution unit 50 It can be calculated and stored in the storage unit 20 as the current instantaneous total electricity consumption (S112).

To this end, the emergency determination unit 41 calculates the instantaneous electricity consumption of each electricity distributor 51-53 by using the detection signal applied from each electricity distributor 51-53, and then all the calculated instantaneous electricity consumption amounts. By summing the , it is possible to calculate the current instantaneous total electricity consumption currently consumed by the distribution unit 50 .

In an alternative example, when one electricity consumption detection unit for detecting the amount of electricity consumed in the entire distribution unit 50 exists in one distribution unit 50, using a detection signal applied from one electricity consumption detection unit The calculated amount of electricity consumption may be determined as the instantaneous total amount of electricity consumed by the distribution unit 50 .

In another alternative example, the emergency determination unit 41 may use the instantaneous total electricity consumption applied from the electricity meter or the electricity rate management server, such as the current accumulated electricity consumption. In this case, the amount of electricity consumption detection unit (514, 524, 534) may be omitted.

As such, when the instantaneous total electricity consumption of the distribution unit 50 (ie, the current instantaneous total electricity consumption) is calculated ( S112 ), the emergency determination unit 41 stores the previous instantaneous total consumption in the storage unit 20 . It may be determined whether the amount of electricity and the calculated current instantaneous total electricity consumption are the same (S113).

If the previous instantaneous total electricity consumption and the current instantaneous total electricity consumption are the same (S113), it may be determined that the real-time consumed electricity amount remains the same even after the second set time elapses. For example, during the second set time period, the television may be continuously turned on.

However, if the previous instantaneous total electricity consumption and the current instantaneous total electricity consumption are different, the emergency determination unit 41 determines that the resident normally lives in the house and uses the electronic product 100 as necessary and stops using it. can do. In this case, the emergency determination unit 41 may determine the current state of the resident of the corresponding house as a normal state in which there is no special emergency.

Therefore, if the previous instantaneous total electricity consumption and the current instantaneous total electricity consumption are different (S113), the emergency determination unit 41 stores the current instantaneous total electricity consumption as the previous instantaneous total electricity consumption in the storage unit 20 ( S114), the process proceeds to step S11 to continuously determine the emergency situation of the resident by using the electricity consumption of the corresponding house.

However, in step S113, if it is determined that the current instantaneous total electricity consumption and the previous instantaneous total electricity consumption are the same, the emergency determination unit 41 does not change the electricity consumption for the second set time. judge the state For example, a resident may have collapsed while watching television in the house and not be able to turn off the television normally.

Therefore, if the current instantaneous total electricity consumption and the previous instantaneous total electricity consumption are the same (S113), the emergency determination unit 41 reads the signal applied from the human body sensor 30 to determine whether a person is present in the house It can be done (S115).

When a person is detected in the house (S115), the emergency determination unit 41 determines whether the detected movement of the person occurs within a third set time (S116, S117).

In this example, the emergency determination unit 41 may also determine whether a person moves by using a signal applied from the human body sensor 30 . For example, by using a signal output from the human body sensor 30, the previously sensed position of the person and the current sensed position of the person are compared, and the emergency determination unit 41 may determine whether or not the person is moving. .

In this case, the third set time is a time much shorter than the second set time, and may be a time for determining whether a person is down.

If a person is currently detected in the house but no movement is detected for the third set time (S116, S117), the emergency determination unit 41 determines that the person is in an emergency state in the house.

Accordingly, the emergency determination unit 41 may output a driving signal to the warning light unit 60 to operate the warning light unit 60 ( S118 ).

Then, the emergency determination unit 41 may transmit an emergency notification message to the manager terminal 80 through the communication unit 70 (S119).

However, if it is determined that there is a person in the house whose movement occurs within the third set time (S117), the emergency determination unit 41 initializes the third elapsed time to '0' and then determines the current house state. Determining the normal state, the determined current instantaneous total electricity consumption is stored in the storage unit 20 as the previous instantaneous total electricity consumption (S120, S121), and then the process may proceed to step S11.

As such, when the instantaneous total electricity consumption does not change for the second set time and there is no movement of a person detected during the third set time, the emergency determination unit 41 operates the warning unit 60 to By notifying the outside of the emergency situation in the house, outsiders can quickly recognize the current emergency and take necessary safety measures.

In addition, by the emergency notification message transmitted to the manager terminal 80, the guardian or the manager can quickly recognize the current emergency.

However, in an alternative example, when the instantaneous total electricity consumption does not change for the second set time, the warning light unit 60 is immediately driven regardless of whether a person is detected and an emergency notification message is transmitted to the manager terminal 80 . can In this case, the motion detection unit 30 may be omitted.
