FIG. 5 is a flowchart illustrating an anomaly detection method for each space in an air conditioner system according to the present invention.

As shown in FIG. 5, the data analysis unit 220 analyzes accumulated data on the stored energy usage (S310). The data analysis unit 220 analyzes the energy usage by space, and analyzes the changes over time.

The data analyzer 220 calculates a normal interval for energy usage, room temperature, indoor humidity, and comfort level. That is, the data analysis unit 220 sets a period in which the energy usage, the indoor temperature, the indoor humidity, and the comfort level can be judged as normal use based on the stored energy usage amount. In addition, you can set the normal section for CO2, dust concentration, and density.

For example, the data analysis unit 220 can set the normal temperature interval and the normal humidity interval to be different from each other according to the seasons, and divide the comfort level into a plurality of steps, and the comfort level is good in the normal temperature interval or the normal humidity interval And the case where it is very good is set as the normal section of the degree of comfort.

The plurality of units measure and store the temperature and humidity of the installed space, and transmit the measured temperature and humidity to the connected controller 50 or the main server 200 (S330). At this time, each unit can measure not only the room temperature and indoor humidity but also CO2, dust concentration, and the number of occupants according to the types of sensors provided.

The watt hour meter 70, the gas meter 80 and the water meter 90 measure the usage amounts of electricity, gas and water and transmit them to the main server 200, respectively. In some cases, the main server 200 can receive usage data from an electric company, a gas company, and a water company.

The control unit 210 compares the measured data with the normal intervals set for the energy usage, the temperature, the humidity, and the comfort level, and determines whether they are included in the normal interval (S340).

If the measured data is included in the normal period as a result of comparing the measured data with the normal period, the controller 210 determines normal operation (S350).

On the other hand, if the measured data is not included in the normal section, the controller 210 diagnoses an abnormality (S360). At this time, the controller 210 diagnoses an abnormality of each of the energy usage, the temperature, the humidity, and the comfort, and outputs a warning accordingly (S370). The control unit 210 may display a warning mark on the control screen to indicate that there is an error.

If the controller 210 determines that it is abnormal, the controller 210 outputs the diagnostic result and the inspection guide (S380). At this time, the inspection guide includes a countermeasure or a solution according to the diagnosis result.

The control unit 210 stores the data related to the normal judgment and the abnormality diagnosis as history data, respectively (S390).

6A to 6C are diagrams for explaining a space-specific analysis method of the air conditioner system according to the present invention.

As shown in FIG. 6A, the controller 210 outputs the amount of energy used and the degree of comfort on the control screen based on the measured data.

At this time, in outputting the energy usage amount, the horizontal axis represents the degree of comfort, and the vertical axis represents one of indoor temperature, indoor humidity, CO2, dust concentration, and occupational density. Data on the vertical axis may be limited to data that can be set to the type of sensor provided in the unit.

The control unit 210 divides the energy usage into layers and displays them in a circle, and the sizes of the circles are displayed differently according to the amount of energy used for each layer. That is, the larger the amount of energy used per space, the larger the size of the corresponding circle.

In addition, the control unit 210 displays the colors of the circles differently according to the degree of comfort for each space. The control unit 210 divides the comfort level into very uncomfortable, uncomfortable, normal, pleasant, and very comfortable, sets the position of the horizontal axis, and displays different colors of the circle. For example, if the comfort level is low, it can be displayed in red, and if it is comfortable, it can be displayed in white.

The control unit 210 sets and displays the vertical position of the circle in accordance with the vertical axis data. For example, in the case of room temperature, the temperature range is indicated on the vertical axis, and the position is set for each layer according to the temperature. That is, the energy usage of the control screen varies depending on the amount of usage, and the position of the horizontal axis changes according to the vertical axis and the degree of comfort according to the temperature.

At this time, time 301 is displayed on the screen of the screen, and the amount of energy used for a specific time is displayed. For example, when the time 301 is set to the first time T1, the energy usage for the first time T1 is displayed.

At this time, the degree of comfort is set by the dry bulb temperature and the relative humidity as shown in Fig. 6B. It can be judged to be comfortable when the relative humidity condition in the constant dry bulb temperature range is satisfied. Even when the humidity is normal, the comfort level is set low when the dry bulb temperature is too low.

In displaying energy usage, after selecting a layer for one of the plurality of layers shown, for example, the first layer (1F), the time 301 at the bottom of the screen is changed from the first time T1 to the second When moving to the time T2, the control unit 210 displays a change 302 of the energy usage for the first floor, as shown in FIG. 6C. At this time, the control unit 210 displays the change in a plurality of circles on a time-by-time basis to display a change over time. The control screen displays a change in the amount of energy used in the first floor, and it does not vary significantly with the lapse of time, but remains constant. However, it can be seen that the comfort also changes as the outside air temperature decreases.

FIG. 7 is a view showing an example of a normal section according to anomaly diagnosis of each space in the air conditioner system according to the present invention. FIG.

7, the data analyzer 220 sets the normal interval 306 for the temperature and the normal interval 305 for the comfort level on the basis of the stored data, 306 and the normal interval 305 for the degree of comfort is set as the normal pattern interval 303. In addition, the data analysis unit 220 analyzes the energy data and sets a normal energy usage amount 304 for each space.

The data analyzer 220 sets a normal interval by calculating statistics of data satisfying a predetermined condition for a predetermined period of the stored data.

At this time, the normal pattern section 303 can be changed according to the condition. For example, you can set a normal interval based on any one of the recent 30 data statistics with similar weather conditions, the data statistics of the last 30 days with the same day, the data statistics of the same month of the previous year, or the data statistics of the last 30 days of the weekday or holiday .

The control unit 110 determines that the energy consumption, the normal zone 305 for the degree of comfort, and the normal zone 306 for the temperature are normal for each space.

That is, in the case of the 10th floor (10F), it can be seen that the normal section is satisfied with respect to the temperature and the degree of comfort, but the normal energy consumption is exceeded.

On the other hand, the 8th floor (8F) satisfies all the normal ranges for temperature, comfort, and energy usage.

FIG. 8 is an exemplary diagram referred to for explaining the abnormality diagnosis using the normal section in FIG. 7; FIG.

As shown in FIG. 8A, the 1F 307a is included in the normal pattern section 303 with respect to the temperature and the degree of comfort, and the energy usage is also smaller than the normal energy usage amount 304, ) Is judged to be normal.

On the other hand, as shown in FIG. 8B, the 1F 307b is included in the normal pattern section 303 with respect to the temperature and the degree of comfort, but since the energy usage is larger than the normal energy usage 304, (210) judges that it is abnormal. Accordingly, the control unit 210 outputs a warning mark to the 1F 307b.

As shown in FIG. 8C, the 1F 307c is included in the normal section with respect to temperature, and the energy usage is also less than the normal energy usage 304, but the comfort level is low and included in the normal pattern section 303 The control unit 210 judges the abnormality and outputs a warning mark.

As shown in (d) of FIG. 8, the 1F 307d is smaller than the normal energy usage amount 304 but is not included in the normal pattern section 303 because the temperature is higher than the normal section and the comfort level is lower , The control unit 210 determines that it is abnormal and outputs a warning mark.

FIGS. 9A and 9B are views showing the result of the abnormality diagnosis and the countermeasure of the air conditioner system according to the present invention.

If any one of energy usage, temperature, and comfort level is not satisfied, the controller 110 diagnoses an abnormality and displays a warning mark on the screen.
