The communication unit 210 is a communication interface for the material management device 20 to communicate with the battery device 10 and the support material distribution center 30 . For example, the communication unit 210 may be a wireless communication interface that connects to a cellular network, or a LAN interface that connects to a wireless LAN or wired LAN. The communication unit 210 receives power information from the battery device 10 and transmits support information to the support goods distribution center 30 . A communication path between the material management device 20 and the support material distribution center 30 may include a wide area network such as the Internet or a dedicated line.

The input unit 220 is, for example, an input device such as a mouse, keyboard, or touch panel. The input unit 220 receives input operations to the material management device 20 . The input unit 220 outputs input information to the control unit 250 .

The display unit 230 is, for example, a display device such as a liquid crystal display, an organic EL display, or a touch panel. The display unit 230 can display any specified information under the control of the control unit 250 .

The storage unit 240 is, for example, a storage device such as an HDD or flash memory. The storage unit 240 stores various information related to the operation of the material management device 20 . For example, the storage unit 240 records programs executed by the control unit 250, setting information, and the like. For example, the storage unit 240 may store power information acquired from the battery device 10 or may store support information provided to the support goods distribution center 30 .

The control unit 250 has a control function of the material management device 20 . For example, the control unit 250 includes an information acquisition unit 251 , a supply destination identification unit 252 , an estimation unit 253 , a supply necessity determination unit 254 , a supply amount determination unit 255 and an information output unit 256 . The information acquisition unit 251 acquires device power information from each battery device 10 by communication via the communication unit 210 . The information acquisition unit 251 records the acquired power information in the storage unit 240 .

The supply destination identification unit 252 identifies the supply destination of the material based on the position information of the battery device 10 . As described above, in the present embodiment, it is assumed that the position information of the battery device 10 is included in the power information and supplied to the material management device 20 . The supply destination specifying unit 252 acquires position information from the power information received from the battery device 10 and specifies a location identified by the acquired position information as a supply destination of the material related to the equipment of the battery device 10 . For example, when the location information of the battery device 10 that supplies power to the refrigerator is obtained, the supply destination identification unit 252 identifies the location identified by the location information as the supply location of the food, drink, and other items stored in the refrigerator. Identify as destination. By specifying the supply destination of supplies in this way, supplies can be supplied to a plurality of shelters.

The estimating unit 253 estimates various types of information necessary for determining the supply amount of each material for each supply destination based on the power information acquired from the battery device 10 . The estimation unit 253 notifies the supply amount determination unit 255 of the estimation result of various information. The estimating unit 253 includes, for example, a device estimating unit 261, a material estimating unit 262, an operation estimating unit 263, and a consumption estimating unit 264.

Each estimation unit may estimate the target by comparing the feature amount extracted from the power information with dictionary information prepared in advance for the feature amount. The feature quantity may be of any type as long as it contributes to the estimation of the target. For example, the feature amount may be related to variation patterns or statistical values. In this case, each estimating unit can select dictionary information indicating a feature amount similar to the extracted feature amount, and use the label associated with the selected dictionary information as the target estimation result. Further, for example, each estimation unit may estimate the target using a learned model generated by machine learning of power information. The machine learning method may be supervised learning, unsupervised learning, or reinforcement learning. Machine learning algorithms are not limited to specific algorithms. Machine learning algorithms may be appropriately selected from arbitrary algorithms such as neural networks, deep learning, support vector machines, decision trees, linear regression, random forests, k-nearest neighbors, and k-means, depending on the properties of the estimation target. .

Based on the power information, the device estimation unit 261 estimates the type of device (hereinafter referred to as “target device”) that operates with the power consumption indicated by the power information. For example, the device estimation unit 261 estimates the type of the target device based on the feature amount related to the power consumption fluctuation pattern.

The material estimation unit 262 estimates materials consumed in relation to the operation of the target device based on the power information. For example, the commodity estimation unit 262 recognizes the time period during which the refrigerator was used based on the electric power information acquired for the refrigerator, and estimates that the commodity highly related to the recognized time period was consumed. can be done. For example, if it is recognized that the refrigerator has been used during breakfast hours, it can be estimated that ingredients such as bread, milk, and eggs that are likely to be used for breakfast have been consumed. The commodity estimation unit 262 may combine other information with the power information in estimating the consumed commodity. For example, if the goods stored in the refrigerator are known in advance, the goods estimation unit 262 may select the goods estimated to have been consumed from the stored goods. Further, when the power information to be acquired is not associated with the target device, the commodity estimation unit 262 may estimate the consumed commodity using the estimation result of the device estimation unit 261 .

Also, the material estimation unit 262 may estimate the number of times the target device is used based on the power information, and estimate the type of material consumed based on the estimated number of times of use. For example, the goods estimation unit 262 estimates, based on the power information, whether or not a device with a fixed number of uses per day is used. It can be presumed that the material used with it was consumed. Also, for example, when the use of the microwave oven for meals is recognized three times a day, the goods estimation unit 262 can estimate that frozen food was consumed by the use of the microwave oven.

That is, the material estimation unit 262 estimates the timing at which the equipment was used or the number of times the equipment was used based on the power information, and estimates the type of material consumed based on the estimated timing or the number of times the equipment is used. It can be said that

The operation estimation unit 263 estimates an operation performed on the target device based on the power information. For example, in a refrigerator, when the temperature inside the refrigerator rises due to the opening and closing of the door, the power consumption rises temporarily because the compressor is activated to accelerate the cooling of the inside of the refrigerator. Therefore, by detecting the timing when the power consumption rises in this way, it is possible to estimate whether the door has been opened or closed. Further, for example, a microwave oven having a range function and an oven function differs in power consumption depending on the functions used. Therefore, by detecting such a difference in power consumption, it is possible to estimate whether the operation using the range function or the oven function has been performed.

The consumption amount estimator 264 estimates the amount of material consumed in relation to the operation of the target device based on the power information. For example, when the usage amount of the target device and the consumption amount of the material are proportional, the consumption estimation unit 264 calculates the amount of the material according to the total power consumption (an example of the usage amount) of the target device calculated based on the power information. can be estimated to have been consumed. For example, since the toilet light and toilet paper are used each time the tray is used, toilet paper consumption may be proportional to toilet light usage. In this case, the consumption estimation unit 264 can estimate the toilet paper consumption according to the total power consumption of the lighting equipment. Toilet paper is one example of a material that may be provided in a sanitary facility. For example, the consumption estimation unit 264 may estimate the consumption of toiletries (soap, toothpaste, shampoo, etc.) based on the power information of the lighting equipment in the washroom. Also, in evacuation shelters, toilet water, water used for washing clothes, etc. are also supplies, so the amount of water used for these purposes may be estimated based on the power information of the lighting equipment.

Also, the consumption estimation unit 264 may estimate the material consumption based on the estimation results of the device estimation unit 261 , the material estimation unit 262 , and the operation estimation unit 263 . For example, the consumption amount estimation unit 264 obtains the number of times the door of the refrigerator is opened and closed based on the detection result of the operation estimation unit 263, and estimates that the amount of goods stored in the refrigerator has been consumed according to the number of times the door has been opened and closed. can be done. Also, the consumption estimation unit 264 may estimate the consumption of the material estimated to be consumed by the material estimation unit 262 . Also, the consumption estimation unit 264 may recognize the number of times the rice cooker has been used based on the power information acquired for the rice cooker, and estimate that rice has been consumed according to the number of times of use. In addition, the consumption estimation unit 264 recognizes the number of times the range function of the power information has been used based on the power information acquired for the microwave oven, and estimates that the frozen food corresponding to the number of times of use has been consumed. good. Also, the consumption amount estimation unit 264 may change the estimated material consumption amount depending on the timing at which the target device is used. For example, the consumption amount estimation unit 264 may estimate that more ingredients are consumed at dinner than at breakfast.

That is, the consumption estimating unit 264 determines whether a heat retaining device (for example, a refrigerator) that has a storage for storing goods and adjusts the temperature in the storage is opened or closed based on fluctuations in the power consumption of the heat retaining device. It can be said that the number of times is estimated, and the amount of consumption of the goods stored in the storage is estimated based on the estimated number of times the storage is opened and closed.

In addition, the consumption estimating unit 264 estimates the amount of use of the equipment (for example, an electric cooker, an electric pot, etc.) that consumes materials with its use based on the fluctuation of the power consumption of the equipment, and estimates It can be said that the amount of consumption of materials caused by the use of equipment is estimated based on the amount of equipment used.

In addition, the consumption estimation unit 264 estimates the amount of lighting equipment used in sanitary equipment (for example, sanitary equipment such as toilets, washrooms, and bathrooms) based on fluctuations in the power consumption of the lighting equipment. It can be said that the consumption amount of materials installed in the facility is estimated based on the usage amount of the lighting equipment.

Also, the consumption estimation unit 264 may calculate the current estimated remaining amount of each material based on the estimated consumption of each material. For example, the consumption estimating unit 264 can calculate the current estimated remaining amount of materials by subtracting the amount of material consumption that has occurred from the reference time to the present time from the remaining amount of materials at the past reference time.

The supply necessity determination unit 254 determines necessity of supply of materials to each supply destination based on the estimation result of the estimation unit 253 . For example, the supply necessity determining unit 254 acquires the estimation result of the remaining amount of each material from the consumption amount estimating unit 264, and determines that supply is necessary for the material whose remaining amount is equal to or less than a predetermined threshold. The determination result of the necessity of supply may be the necessity of supply in units of goods, or the necessity of supply in units of supply destinations. Information indicating the determination result as to whether or not supply is necessary may be sent to the support supply distribution center 30 as support information instead of/in addition to information indicating the supply amount of each supply determined by the supply amount determination unit 255 .

The supply amount determination unit 255 determines the supply amount of materials to each supply destination based on the estimation result of the estimation unit 253 . The supply amount determination unit 255 generates support information indicating the supply amount determined for each material, and transmits the generated support information to the support material delivery center 30 . For example, the supply amount determination unit 255 may be configured to determine the consumption amount of each material estimated by the consumption amount estimation unit 264 as the supply amount of each material.

Further, the supply amount determining unit 255 may be configured to compare the remaining amount of each material estimated by the consumption amount estimating unit 264 with a threshold, and determine the supply amount of the material whose remaining amount is equal to or less than the threshold. good. In this case, the supply amount determination unit 255 predicts future fluctuations in the remaining amount of supplies after supply based on past fluctuations in the remaining amounts of the supplies, and based on the prediction results, determines whether the supplies are supplied. The supply amount of the material may be determined so that the remaining amount does not become equal to or less than the threshold until at least a predetermined period of time has elapsed since the material supply.

For example, the supply amount determination unit 255 cumulatively adds the supply amount of each material determined for each evacuation center and cumulatively subtracts the consumption amount of each material estimated for each evacuation center. manages the remaining amount of each item in each evacuation center. For example, the supply amount determination unit 255 manages the remaining amount and the threshold value of each item in each evacuation center using a remaining amount management table TB illustrated in FIG. In FIG. 4, the numerical value outside ( ) represents the remaining amount, and the numerical value within ( ) represents the threshold value. In this case, the supply amount determination unit 255 determines the necessary supply amount (for example, +200) for the “frozen food C” of the shelter X whose remaining amount (500) is equal to or less than the threshold (600), and determines the determined supply amount. The amount is notified to the support material delivery center 30 by the support information.

The information output unit 256 outputs information indicating various estimation results estimated by the estimation unit 253 (hereinafter referred to as “estimation result information”) to an output unit according to a predetermined output mode. For example, the information output unit 256 outputs estimation result information including the consumption amount and remaining amount of each material estimated by the consumption amount estimation unit 264 . For example, when the information output mode is information display, the information output unit 256 may output the estimation result information to the display unit 230 . Further, for example, when the mode of information output is information recording, the information output section 256 may output the estimation result information to the storage section 240 . Further, for example, when the mode of information output is transmission of information, the information output section 256 may output the estimation result information to the communication section 210 .

However, if the location information of each battery device 10 is registered in advance in the resource management device 20, or if the location information of the battery device 10 is provided to the resource management device 20 from a device other than the battery device 10, the battery device 10 The transmission of the location information to the material management device 20 by , may be omitted. Similarly, when equipment information about each battery device 10 is registered in advance in the material management device 20, or when equipment information is provided to the material management device 20 from a device other than the battery device 10, material management by the battery device 10 is performed. The transmission of device information to device 20 may be omitted.

Subsequently, in the goods management device 20, the consumption estimation unit 264 estimates the consumption of goods in each shelter where each battery device 10 is installed based on the power information received from each battery device 10 ( step S107). Subsequently, the supply necessity determining unit 254 determines whether or not each material needs to be supplied for each shelter based on the consumption amount of each material estimated by the consumption amount estimating unit 264 (step S108). Subsequently, the supply amount determination unit 255 determines the supply amount of the material to be supplied to the shelter based on the consumption amount of each material estimated by the consumption amount estimation unit 264 (step S109). The supply amount determination unit 255 generates support information for notifying the support material distribution center 30 of the determined supply amount (step S110), and transmits the generated support information to the support material distribution center 30 (step S111). At the support supply delivery center 30, based on the support information received from the supply management device 20, each supply is delivered to each shelter in the amount determined for each supply (step S112).

Thereafter, step Sn (n is an integer of 1 or more), which is a group of steps S105 to S112, is repeatedly executed at predetermined timings, so that while monitoring the remaining amount of each material in each evacuation center, It will be possible to continuously supply a large amount of goods.

In this embodiment, the supply management system 1 manages the supply of relief supplies to evacuation shelters in the event of a disaster. There is no need for the goods to be managed to be relief goods. The goods management system 1 of the present embodiment can be applied to the management of distribution in which the supply of goods is managed from a remote location, and in which the supplied goods are consumed according to the operation of electrical equipment. can be done.

Further, in the present embodiment, a case has been described in which the material management apparatus 20 determines the supply amount of each material, but the material management apparatus 20 does not determine the supply amount of each material. It may be configured as a device that estimates the consumption amount or the remaining amount and outputs the estimation result.
