(Also referred to as "electrical equipment"), for example, defects or failures occur due to aging or deterioration of the equipment. In order to avoid the influence on business activities, it is preferable to repair or replace the equipment before it breaks down.

Repairs and replacements of equipment installed in convenience stores and supermarket chains that have stores in a wide area are generally managed centrally by the headquarters that controls the stores. For example, replacement of equipment in a store is usually carried out under the control of the headquarters. At that time, when the headquarters (management center) receives a contact (report) about equipment failure from the store, it dispatches maintenance personnel to the store, for example, through a maintenance service company (facility management company) of the contractor, etc. Repair or replace equipment.

In stores, houses, commercial buildings, etc., an energy management system (EMS) that visualizes the amount of electric power used and controls equipment for saving electricity has been commercialized. For example, EMS for residential use is also called HEMS (Home EMS), and EMS for commercial buildings is also called BEMS (Billing EMS).

In relation to energy management of stores and the like, for example, Patent Document 1 discloses a power management server that efficiently suppresses power consumption of stores. This power management server is a power consumption acquisition means for acquiring the power consumption of a store or the power consumption of an installed electric device, and a notification for the purpose of reducing the power consumption based on the acquired power consumption information, or an operation of the electric device. The storage device is provided with a management means for controlling, an information acquisition means for acquiring POS (Point Of Sale) information in a store, and a storage device for storing POS information and power consumption information in association with each other. Based on the relationship between the stored past POS information and the power consumption information, it is provided with a power consumption prediction means for predicting the subsequent power consumption in the store from the POS information acquired sequentially.

Further, Patent Document 2 does not include an electric power measuring device by discriminating the state of an electric device by utilizing a characteristic change of an electric power waveform such as a stepped change or an instantaneous high power waveform. It is also described that the device is determined to determine the period during which it is not operating or the period during which power consumption is low.

In Non-Patent Documents 1 and 2, the current waveform flowing through the main trunk of the distribution board is measured, transferred to a cloud server, observed, and the waveform is generated for each device by a separator or the like learned by machine learning on the cloud server. A device separation technique that separates and estimates the power consumption of each device and the on / off of each device is disclosed.

In Non-Patent Document 3, each sensor, camera, etc. detects signs of abnormality or failure of store equipment, notifies a remote office with an alarm, visualizes the operating status of store equipment, and enables prompt repair response. The case was disclosed.

In Non-Patent Document 4, as an example of the relationship between the temperature of the refrigerator and the power consumption (profiling), when the power suddenly increases according to the temperature (low efficiency), the equipment is aged, the outdoor unit environment is deteriorated, and the like. When the electric power is constant against changes in temperature (always in a full operating state), the capacity of the refrigerator is insufficient, and the environment of the outdoor unit is deteriorated.

FIG. 5A is a diagram schematically illustrating an example of the configuration of the EMS cloud server 10 of FIG. Note that FIG. 5A is a diagram illustrating a detailed example of FIG. 4, and the same reference reference numerals are given to the same and equivalent elements as those in FIG. Hereinafter, the differences from FIG. 4 will be described with reference to FIG. 5 (A). The information acquisition unit 11 includes a current waveform acquisition unit 111 that acquires a current waveform transmitted from the communication device 21 of the store 20. The evaluation unit 12 includes an equipment separation unit 121, a deterioration status evaluation unit 122, and an operating rate acquisition unit 123.

The current waveform acquisition unit 111 may periodically acquire the power consumption and the current waveform in a predetermined time interval (time interval) from the communication device 21 of the store 20. Alternatively, in the case of the store 20 which is open 24 hours a day, for example, the power consumption and current of a predetermined time section from the communication device 21 of the store 20 at a predetermined fixed time for each of morning, morning, noon, afternoon, evening, and night. The waveform may be acquired. The acquired power consumption and current waveform may be transmitted to the EMS cloud server 10 side by starting from the communication device 21 side of the store 20. Alternatively, conversely, the communication device 21 of the store 20 may transmit the power consumption and the current waveform to the EMS cloud server 10 by starting from the EMS cloud server 10 side. For example, the current waveform acquisition unit 111 transmits a request for power consumption and current waveform to the communication device 21 of the store 20, and the communication device 21 of the store 20 that receives the request stores and holds the request. The power consumption and current waveforms may be transmitted to the EMS cloud server 10. Alternatively, the communication device 21 of the store 20 that receives the request requests the current sensor 23 or the like (FIG. 2A) to measure the current waveform, and transmits the measured current waveform to the EMS cloud server 10. You may.

The device separation unit 121 converts the entire current waveform of the store 20 transmitted from the communication device 21 of the store 20 into a current waveform for each device by, for example, the device separation technology disclosed in Non-Patent Documents 1, 2, and the like. It may be separated. In the case of the configuration in which the communication device 21 of the store 20 acquires the current waveform of each device and transmits it to the EMS cloud server 10 as shown in FIGS. 3 (A) and 3 (B), the device separation unit 121 It is not necessary to separate the current waveform by.

The deterioration status evaluation unit 122 estimates the deterioration status of the device based on the current waveform of each device separated by the device separation unit 121 or the current waveform of each device transmitted from the communication device 21. For example, in air-conditioning / refrigerating equipment, if the compression efficiency of the refrigerant gas decreases due to a defect or deterioration over time in the compressor or the like, the high-speed operation time until the set temperature is reached becomes long, and the power consumption increases. Further, in air-conditioning / refrigerating equipment and the like, the time of low-speed operation for maintaining the set temperature occupies most of the operating time, so that when the efficiency of low-speed operation deteriorates, the power consumption increases remarkably. In this way, when the power consumption pattern and distribution of the device to be evaluated deviate significantly from the standard, it can be seen that the device is deteriorating. The deterioration status evaluation unit 122 may quantify the degree of deviation from the standard of power consumption of the device to be evaluated to represent the deterioration status.

The deterioration status evaluation unit 122 may estimate the failure or defective state of the device by utilizing the characteristic change of the current waveform pattern at the time of switching the operation of the device. The deterioration status evaluation unit 122 may group or quantify the degree of deviation of the current waveform pattern from the standard (for example, the settling time is significantly delayed) to represent the deterioration status.

The deterioration status evaluation unit 122
・ Relationship between aging of equipment and power consumption,
・ Correspondence between temperature and power consumption of equipment,
・ Number of visitors,
・ Store scale,
·amount of sales,
The degree of deterioration of each device may be evaluated based on the above.

Regarding the aging and power consumption of the above equipment, the deterioration status evaluation unit 122 evaluates the deterioration status of the equipment from the measured value of the power consumption of the equipment in consideration of the increase in power consumption due to the aging of the equipment. May be good. For example, in air conditioning equipment such as air conditioners, it is said that the current consumption increases by, for example, about 20% in 5 years and by, for example, about 50% in 10 years due to aging. Therefore, when the equipment to be evaluated is an air conditioner such as an air conditioner, if the measured value of the power consumption is within the standard fluctuation range of the power consumption due to aging, the deterioration status evaluation unit 122 deteriorates due to aging. If it is significantly out of the standard fluctuation range (for example, if it is statistically far from other values), it is judged that there is a defect or failure other than deterioration due to aging. To do. Alternatively, when the device to be evaluated is a refrigerator, the deterioration status evaluation unit 122 uses the device based on the relationship between the temperature and the power consumption of the refrigerator (power consumption increase rate) described in Non-Patent Document 4 described above. The deterioration status of (for example, a refrigerator) may be evaluated. Further, when the device to be evaluated is a door switch, the number of visitors may be used as a variable in the analysis of power consumption. That is, in a store where the number of visitors is larger than that of other stores, the number of times the door switch is opened and closed increases, and the power consumption (cumulative value) also increases. Therefore, the deterioration status evaluation unit 122 may evaluate the deterioration status from the power consumption of the door switch in consideration of the number of visitors and the like.

Further, the deterioration status evaluation unit 122 may perform a statistical test on the presence or absence of deterioration of the device.

Alternatively, stores having substantially the same store size, location, sales, and number of visitors (similar ones) may be classified into the same group (cluster). In this case, the deterioration status evaluation unit 122 determines the power consumption of the equipment to be evaluated for the store in which the equipment to be evaluated for the deterioration status is installed, for example, the corresponding device in the same group as the group to which the store belongs. By comparing the power consumption in the same time zone as a reference, the abnormality and deterioration status of the power consumption of the device may be evaluated. In this case, the deterioration status evaluation unit 122 uses the time-series data of the power consumption of the device to be evaluated for a predetermined time period in the same time zone of the corresponding device in the store belonging to the same group as the store in which the device to be evaluated is installed. It may be compared with the time series data of the power consumption in. The deterioration status evaluation unit 122 sets the statistical value (average, variance) of the power consumption of the device to be evaluated and the corresponding device in the same time zone in a plurality of stores belonging to the same group as the store in which the device to be evaluated is installed. The power consumption statistics (mean, variance) may be compared.

The deterioration status evaluation unit 122 selects a device evaluated to be in a state of advanced deterioration as a device to be replaced or a device to be repaired. Lighting equipment and the like may be replaced, but air conditioning equipment and the like may not be replaced as a whole, but may be, for example, repair of a compressor or an outdoor unit or replacement of parts. The deterioration status evaluation unit 122 may express the deterioration status of the device numerically, for example, from 1 stage to 5 stages.

The operating rate acquisition unit 123 may acquire the operating rate of the device based on the operating rate information for each device transmitted from the communication device 21 of the store 20. For example, in the case where the device of the store 20 is connected to the home outlet via the smart taps 25A to 25C of FIG. 3A, or the devices 26A to 26C having the power measurement function and the communication function of FIG. 3B. , Smart taps 25A to 25C or devices 26A to 26C transmit the operating rate (for example, the ratio of operating time) of each device to the communication device 21, and the communication device 21 transmits to the EMS cloud server 10. Good.

Alternatively, the operating rate acquisition unit 123 estimates the operation, stop, etc. of the device based on the characteristic waveform of the current waveform data for each device separated by the device separation technology, and acquires the operating rate. May be good.

The priority setting unit 13 sets the priority of repair and replacement based on the deterioration status of the device evaluated by the deterioration status evaluation unit 122 and the operation rate of the device acquired by the operation rate acquisition unit 123. Repairs and replacements are performed from the equipment with the highest priority. The priority may be a numerical value, or may be ranked or categorized such as A rank and B rank. The priority setting unit 13 may classify the equipment to be repaired or replaced not only by priority but also by ranking or category.

The priority setting unit 13 may set the priority of repair and replacement based on the operating rate of the equipment in one store. For example, priorities may be given to different types of devices (one for each) in one store according to their respective operating rates. Alternatively, priorities may be given to a plurality of devices of the same or the same type installed in one store according to their respective operating rates.

Alternatively, the priority setting unit 13 may set the priority of repair or replacement based on the operating rate in the plurality of stores. In this case, priorities may be given to the same or the same type of equipment installed in the plurality of stores according to their respective operating rates. For example, if the operating rate of a coffee maker (coffee machine) in one store A is higher than the operating rate of a coffee maker in another store B, the priority of repairing or replacing the coffee maker (coffee machine) in store A is set. It may be higher. Alternatively, priorities may be given to a plurality of devices of different types installed in a plurality of stores according to their respective operating rates.

In the priority setting unit 13, for example, when the deterioration of the device is progressing (the state of deterioration of the device is 4 or 5 stages) and the operating rate of the device is high, the priority of repair or replacement of the device is increased. May be good.

Alternatively, the priority setting unit 13 may give higher priority to repair and replacement as the operating rate of the equipment in the store is higher, even if the equipment has not deteriorated.

Alternatively, the priority setting unit 13 may set a high priority for a device having a low operating rate, and preferentially repair or replace the device having a low operating rate. This guides the user to select a period during which the device is not operating and repair or replace the device.

In the present embodiment, as a modification of the priority setting unit 13, instead of the operating rate of the device, the priority of repair or replacement of the device may be set based on the sales forecast information between stores. That is, as shown in FIG. 5B, the evaluation unit 12 includes an equipment separation unit 121, a deterioration status evaluation unit 122, and a sales forecast unit 124.

The priority setting unit 13 sets the priority of repairing or replacing the device based on the deterioration status of the device from the deterioration status evaluation unit 122 and the sales forecast information of the store acquired by the sales forecast unit 124.

The sales forecasting unit 124 may forecast future sales from the sales information of the store 20 acquired by the EMS cloud server 10 by a method such as regression analysis (curve fitting of an approximate curve). Alternatively, the sales forecasting unit 124 may acquire the sales forecast between stores from the headquarters 40 (FIG. 1), which is a client of the cloud service, via the information acquisition unit 11. The sales forecasting unit 124 acquires the sales forecasting information of the plurality of stores 20, and the priority setting unit 13 repairs or replaces the equipment based on the sales forecasting information of the plurality of stores 20 acquired by the sales forecasting unit 124. The priority may be set. In this case as well, the priority may be a numerical value, or may be ranking or categorization. The priority setting unit 13 may classify the equipment to be repaired or replaced not only by priority but also by ranking or category.

Alternatively, in FIG. 5B, the sales forecasting unit 124 acquires the measured value of the sales by collecting the POS information of the store 20, for example, and the priority setting unit 13 obtains the measured value of the sales based on the measured value of the sales. You may want to set the priority of equipment repair and replacement.

The priority setting unit 13 may raise the priority of repairing or replacing the equipment of the store where the increase in sales is expected, even if the deterioration of the equipment has not progressed.

As a further modification of the priority setting unit 13, the priority of repair or replacement of the device may be set based on the deterioration status of the device, the operating rate of the device, and the sales forecast between stores.

Alternatively, the priority setting unit 13 may set the priority of repair or replacement of the device according to what the classification of the deteriorated device is. For example, air conditioning equipment and freezing / refrigerating equipment are known to account for most of the power consumption in the store 20. In addition, depending on the delay in recovery from the failure of the freezing equipment, there is a possibility that all the displayed products (frozen foods, etc.) will be destroyed. Therefore, even if the priority setting unit 13 sets the priority so that the repair or replacement of equipment such as freezing / refrigerating equipment and air conditioning equipment is prioritized over the repair and replacement of other equipment. Good. That is, the priority setting unit 13 may set the priority according to the classification of the devices.

The result reporting unit 14 includes a repair / exchange information generation unit 141 and a repair / exchange information transmission unit 142. The repair / replacement information generation unit 141 creates repair / replacement information for the device. Although not particularly limited, the device repair / replacement information includes, for example, store information in which the device to be repaired or replaced is installed, information on the device, and priority. The repair / replacement information transmission unit 142 transmits the repair / replacement information of the device to the headquarters 40 via the communication unit 17.

FIG. 6A is a diagram illustrating an example of store information stored in the storage unit 15 of FIG. 4 or FIG. 5A. Although not particularly limited, the store information includes identification information (ID), store name (name), address, location, sales floor area, parking lot, sales, number of visitors, device information, and the like. As shown in FIG. 6B, the device information includes columns for device ID, classification, device name, product number, installation location (option), history, nominal power, operating rate, and power consumption. The power consumption column may be configured to point to the location (record data, file, etc.) of the time series data or the current waveform data of the power consumption instead of the actual data. In addition, at least one item of the store information of FIG. 6A may be used for the above-mentioned classification of stores into groups (clusters) and sales forecast.

FIG. 6C is a diagram illustrating an example of repair / replacement information (equipment subject to repair / replacement, priority, and store) created by the repair / replacement information generation unit 141 of FIG. 5A. Although not particularly limited, the repair / replacement information sets the ID of the store where the equipment is repaired / replaced, the store name, the equipment to be repaired / replaced, the equipment ID, the name, the product number, the installation location, and the priority of the repair / replacement. .. The priority of repair and replacement of the air conditioner AC2 in store A is set high. The priority may be a numerical value in the range of 0 to 10, for example, in addition to the three levels of high, medium, and low. The repair / replacement information of FIG. 6C is transmitted to the headquarters 40 of FIG. 1 by the repair / replacement information transmission unit 142 of FIG. 5A.

Next, the operation of this embodiment will be described. FIG. 7 is a flow chart illustrating an example of the operation of the EMS cloud server 10 (configuration for separating devices based on the current waveform) in the present embodiment described with reference to FIG. 5 (A).

The EMS cloud server 10 acquires the current waveform data of the main trunk or the branch breaker of the distribution board from the communication device 21 of the store 20 (S11).

The device separation unit 121 of the EMS cloud server 10 separates into current waveforms of each device by the device separation technique (S12).

The deterioration status evaluation unit 122 of the EMS cloud server 10 evaluates the deterioration status of each device (S13).

The priority setting unit 13 of the EMS cloud server 10 sets the priority of repair and replacement for the device to be repaired and replaced (S14).

The repair / replacement information generation unit 141 of the EMS cloud server 10 creates a report of equipment repair / replacement information (S15).

The repair / replacement information transmission unit 142 of the EMS cloud server 10 transmits a device repair / replacement information report (for example, FIG. 6C) to the headquarters 40 (S16).

FIG. 8 is a flow chart illustrating an example of the procedure for evaluating the deterioration state of FIG. 7 (S13).

The deterioration status evaluation unit 122 of the EMS cloud server 10 classifies, for example, a plurality of stores having substantially the same (similar) store size, location, sales, and number of visitors into the same group (cluster) (S131). Alternatively, the categorization of the stores into clusters in step S131 may be performed in advance in the EMS cloud server 10 and stored in the storage unit 15 instead of being performed by the deterioration status evaluation unit 122. Alternatively, if it is available by contract or the like, the EMS cloud server 10 may acquire information in which the store 20 is classified into a group (cluster) or related information from the headquarters 40 that controls the store 20.

The deterioration status evaluation unit 122 acquires the power consumption (for example, a value converted into the power consumption amount) of the corresponding device of at least one store belonging to the same group as the store in which the device to be evaluated is installed (S132).

The deterioration status evaluation unit 122 of the EMS cloud server 10 compares the equipment to be evaluated for the deterioration status with the power consumption and the like of the corresponding equipment in the stores of the same group (S133).

In the deterioration status evaluation unit 122 of the EMS cloud server 10, when the power consumption of the device to be evaluated is larger than the power consumption of the corresponding device of the same group by, for example, a predetermined ratio, the device to be evaluated is deteriorated. It is evaluated as being done (S134). The deterioration status evaluation unit 122 may compare the power consumption of the device to be evaluated with the average value of the power consumption of a plurality of corresponding devices in a plurality of stores in the same group. The deterioration status evaluation unit 122 calculates the degree of deterioration (progress of deterioration) based on the ratio of the power consumption Wref of the corresponding devices in the same group to the power consumption W1 of the device to be evaluated, the statistical processing result thereof, and the like. You may do so. For example, the ratio: W1 / Wref × 100 may be set to a numerical value or rank indicating that the state of deterioration is progressing according to 110%, 120%, 130%, ....

According to the above embodiment, the EMS cloud server 10 gives priority to repair or replacement of information on a device that is deteriorated and needs to be repaired or replaced, for example, before the device installed in the store 20 is deteriorated and a failure occurs. By adding degree information and presenting it to the headquarters 40, it is possible to properly repair and replace the equipment in consideration of the sales activity situation at the store etc., and an operating loss occurs due to a sudden equipment failure etc. Can be avoided.

In the above embodiment, the description is based on an example in which a device management device is mounted on an EMS cloud server 10 that connects to the Internet or the like and provides a cloud service. However, the device management device includes power consumption, current waveform, etc. of the device in the store. Can be implemented in any network node as long as it can be acquired.

In the above embodiment, some examples in which the communication device 21 is configured by the HEMS controller and the meter reading data (power consumption, etc.) of the smart meter 31 is acquired in real time from the B route or the like have been described, but the EMS cloud server 10 or The headquarters 40 may acquire meter reading data (power consumption, etc.) acquired by the power supply business owner 30 from the smart meter 31 of the store 20 via route A as the power consumption of the store 20. For example, the EMS cloud server 10 or the headquarters 40 may access the information providing site of the power supply business owner 30 to acquire the power consumption (or its transition information, etc.) of the store 20 (however, it is not real-time information but Power consumption information for about 1 hour).
