Hereinafter, with reference to the drawings will be described a customer management method for determining whether or not the person activity / inactivity in the customer (100_1, ... 100_N) using the customer management apparatus 200 according to the present invention.

1 to 3, each of the plurality of meter reading devices 101, 102, 104 in the customers 100_1,... 100_N may use the electricity, gas, and water consumption of the customers 100_1,. The meter may be read and the metered amount may be transmitted to the data concentrator 110 (S10).

The data collection device 210 of the customer management device 200 may output the meter data DATA of the customers 100_1,... 100_N transmitted from the data concentrator 110 to the control device 220.

The reference value calculator 223 of the control device 220 may calculate the determination reference value Ref1 from the electricity consumption of the meter data DATA output from the data collection device 210 (S21).

For example, the reference value calculator 223 may calculate the determination reference value Ref1 from the electricity consumption, that is, the constant electricity usage, among the meter reading data DATA collected by the data collection device 210 for a predetermined period of time. Can be.

1 to 4, the reference value calculator 223 may calculate the determination reference value Ref1 from the constant electricity consumption by the curve fitting method.

In other words, the reference value calculator 223 may extract a plurality of peak points from the constant electricity usage by using the curve fitting method.

Subsequently, the reference value calculator 223 removes signals other than the peak point through at least one noise removing operation, extracts one peak point having the lowest value among the extracted plurality of peak points, and determines the determination reference value Ref1. Can be calculated.

1 to 3 and 5, the reference value calculator 223 may calculate the determination reference value Ref1 from the constant electricity consumption through a fast Fourier transform (FFT) method.

In other words, the reference value calculator 223 may calculate the signal of the frequency component from the constant amount of electricity using the fast Fourier transform method. Subsequently, the low frequency component may be removed from the signal of the frequency component calculated based on the set reference cycle, that is, the reference frequency. The signal from which the low frequency component has been removed may be converted into a signal of a time component using a fast Fourier inverse transform (IFFT) method, and the determination reference value Ref1 may be calculated by extracting the maximum value of the converted signal.

Referring back to FIGS. 1 to 3, the determination unit 225 of the control device 220 may determine the electricity consumption of the meter reading data DATA output from the data collection device 210 and the reference value calculation unit 223. The reference value Ref1 may be compared to determine whether a person in the customers 100_1,... 100_N is active or inactive (S23).

For example, if the electricity usage of the meter reading data DATA is greater than the determination reference value Ref1, the determination unit 225 may determine that a person in the customers 100_1,..., 100_N is in an active state (S14).

The determination unit 225 may output the determination result DR to the alarm counter 227, and the alarm counter 227 may decrease the counter value according to the determination result DR (S27).

Subsequently, the determination unit 225 may determine whether a person in the customers 100_1,... 100_N is active / inactive from the gas usage amount or the water consumption amount of the meter reading data DATA (S30, S40).

For example, the determination unit 225 may compare the gas usage amount of the meter reading data DATA with the previous gas usage amount of the customers 100_1,... 100_N stored in the storage unit 221 (S30).

As a result of the comparison, when the gas usage of the metering data DATA is greater than the previous gas usage, that is, when a person in the customers 100_1,... 100_N is using the gas, it is determined that the person in the customers 100_1,... It may be (S25).

As a result of the comparison, when the water consumption of the meter reading data DATA is greater than the previous water consumption, that is, when a person in the consumers 100_1, ... 100_N is using the water, it is determined that the person in the consumers 100_1, ... 100_N is active. It may be (S25).

Subsequently, the determination unit 225 may reduce the counter value of the alarm counter 227 by outputting the determination result DR (S27).

However, it is determined that the person within the customers 100_1, ... 100_N is inactive from the electricity consumption of the meter reading data DATA (S29), and the gas consumption and water consumption of the meter reading data DATA are also inactive. In operation S50, the determination unit 225 may determine whether the person within the customer 100_1, ... 100_N is active / inactive based on the predetermined average activity / inactivity period information AC.

Here, the average activity / inactivity period information (AC) is classified into 24 hours a day as the active time within the customer (100_1, ... 100_N), such as morning to evening, and inactive time, such as night or dawn time It may be one piece of information.

In this case, if the meter reading data DATA is data collected in the average activity period, the determination unit 225 may output the determination result DR to the alarm counter 227, and the alarm counter 227 may determine the determination result DR. In step S60, the counter value may be increased.

In addition, if the meter data DATA is data collected in an average period of inactivity, the determination unit 225 may control the alarm counter 227 to perform a comparison operation.

For example, the alarm counter 227 may compare the counter value increased or decreased according to the determination result DR output from the determination unit 225 with the counter reference value Ref2 (S65).

If the counter value of the alarm counter 227 is greater than or equal to the counter reference value Ref2, the alarm counter 227 may output a control signal CNT capable of generating an alarm event (S70).

The control signal CNT output from the alarm counter 227 may generate an alarm or notify the administrator of the current situation through a text message or a telephone.

According to the alarm event, the manager may perform a follow-up action, for example, the customer 100_1, ... 100_N, in which the alarm event is generated, to check the situation.

However, if the counter value of the alarm counter 227 is smaller than the counter reference value Ref2 as a result of the comparison, the customer management apparatus 200 waits for a predetermined time and then reads the meter reading data DATA output from the data collection apparatus 210. In operation S21, the operation of calculating the determination reference value Ref1 may be repeatedly performed.
