Information processing system and information processing method

Abstract

The amount of contribution to reduction of carbon dioxide gas, which is achieved by a drive system having a drive device being replaced from a reference system to a target system, is determined as a more actual value. The sensor (123) actually measures a first amount of power consumed by the object system by the drive device. A first conversion unit (201) converts the first power consumption amount, and acquires a first emission amount of carbon dioxide gas emitted during power generation with a power amount equivalent to the first power consumption amount. The acquisition unit (202) uses a power consumption model that derives power consumption on the basis of the control mode of the drive device, and acquires a second power consumption amount that will be consumed in accordance with the control mode of the reference system. A second conversion unit (203) converts the second amount of power consumed, and acquires a second amount of emission of carbon dioxide gas that is emitted during power generation with an amount of power equivalent to the second amount of power consumed. A calculation unit (204) calculates the difference between the first emission amount and the second emission amount as a reduction contribution amount.

[0009] Non-patent document 1: Japan LCA Society, "Calculation of Contribution to Greenhouse Emission Reduction", Japan LCA Society, 2nd edition, March 8, 2022 Summary of the Invention

[0010] The problem the invention aims to solve

[0011] There is a widespread demand to reduce greenhouse gas emissions. Emissions from the generation of greenhouse gases generated by the energy consumed in driving equipment can be reduced, for example, by changing the production and transportation processes of goods. The reductions achieved through such methods are called Avoided Emissions. Avoided Emissions are increasingly used, for example, as an indicator to publicize efforts to address environmental issues, and there is a desire to determine them as more realistic values.

[0012] In recent years, the development of methodologies related to greenhouse gas emission planning has been progressing in Japan's chemical, electrical, and electronics industries. However, these methodologies are specific to particular industries and do not involve estimating the overall contribution of the industry to greenhouse gas emission reduction.

[0013] The Japan LCA Society and the WBCSD (World Business Council for Sustainable Development) are compiling ideas related to the overall contribution of the industry to greenhouse gas emission reduction, with participating companies at the center. Furthermore, the Japan LCA Society and the WBCSD have explored directions for evaluation methods of greenhouse gas emission reduction contributions and published their summarized results. For example, the Japan LCA Society published "Guideline for Estimating Greenhouse Gas Emission Reduction Contributions, 2nd Edition, March 8, 2022" (see Non-Patent Literature 1).

[0014] The above guidelines are a compilation of assessments of greenhouse gas emissions. The estimates of reduction contributions are documented as being derived by multiplying by the following three items.

[0015] 1. The net reduction in greenhouse gases by the final products that achieve the reduction effect, relative to a baseline, where the baseline is a life-cycle assessment-based baseline per functional unit.

[0016] 2. The prevalence of end products that achieve the reduction effect.

[0017] 3. Contribution rate of the evaluated products, etc.

[0018] In addition, regarding the setting of the baseline, the following principles related to the setting of the baseline are described below.

[0019] "Products that are widely available even when there is no product to be evaluated (object equipment) are defined as comparison objects (benchmark equipment). When the product to be evaluated (object equipment) is the final product that achieves the reduction effect, the comparison objects (benchmark equipment) are defined as the baseline. The baseline must have the same function as the final product that achieves the reduction effect."

[0020] However, the aforementioned guidelines only provide guidance based on the definition of greenhouse gas emission reduction contributions. Therefore, they do not describe methods for calculating greenhouse gas emissions during operation that matches the characteristics of the target equipment, nor for calculating greenhouse gas emissions generated when a benchmark device, serving as a comparison object and operating for the same purpose as the target equipment, is used. Therefore, there is a need for a method for calculating greenhouse gas emissions based on the operation of industrial equipment used to produce and transport goods, as well as a suitable mechanism for evaluating reduction contributions.

[0021] As industrial equipment used to produce and transport goods, drive systems can be cited as an example. Drive systems consist of motors, inverters, etc., which are energy-consuming drive devices, or machine tools, conveyors, conveying robots, Automated Guided Vehicles (AGVs), etc., which are mechanical devices that contain them.

[0022] To reduce the energy consumed in the production and transportation of goods, it is important to optimize the energy consumption of drive equipment by optimizing the operation of drive equipment.

[0023] Solution for solving the problem

[0024] One implementation of the information processing system provides the contribution of a drive system with a drive device to the reduction of carbon dioxide emissions achieved by replacing a reference system with an object system. This information processing system includes a sensor, a first conversion unit, an acquisition unit, a second conversion unit, and a calculation unit. The sensor actually measures the electrical power consumed by the object system through the drive device, i.e., the first electrical power consumed. The first conversion unit converts the first electrical power actually measured by the sensor to obtain the amount of carbon dioxide emitted during power generation equivalent to the first electrical power consumed, i.e., the first emission amount. The acquisition unit derives a power consumption model based on the control mode of the drive device to obtain the electrical power consumed corresponding to the control mode of the reference system, i.e., the second electrical power consumed. The second conversion unit converts the second electrical power consumed to obtain the amount of carbon dioxide emitted during power generation equivalent to the second electrical power consumed, i.e., the second emission amount. The calculation unit calculates the difference between the first emission amount and the second emission amount as the reduction contribution.

[0025] The effects of the invention

[0026] Using the above method, the reduction contribution can be calculated as a more realistic value. Attached Figure Description

[0034] Figure 8 This is a flowchart illustrating an example of the process involved in calculating emissions from an object system. Detailed Implementation

[0035] The following describes in detail an article production system as an example of an implementation of the drive system, with reference to the accompanying drawings.

[0036] Figure 1 This is a diagram illustrating a summary of embodiments of the present invention.

[0037] like Figure 1 As shown, the information processing device 100 is connected to the database 110. The information processing device 100 calculates the contribution of the drive system with drive equipment in the production system of the article in the factory 120 to the reduction of carbon dioxide gas emissions achieved through updates and provides it to the delivery destination 130.

[0038] In factory 120, items are produced by an updated production system (object system 121). Object system 121 is configured to have multiple object devices 122 as multiple drive devices. Furthermore, in... Figure 1 The object system 121 is composed of three object devices 122, but this structure is ultimately an example, and the number of object devices 122 constituting the object system 121 can be arbitrary.

[0039] Sensors 123 are installed on the object device 122. The sensors 123 actually measure the electrical power consumed by the object device 122 constituting the object system 122 in the production of the article.

[0040] The power receiving and transformation system 124 receives and transforms the power required to operate the factory 120 to supply power to the target system 121. In this embodiment, the power required to operate the factory 120 is supplied from multiple power sources, and the proportion of power supplied from each power source is changed in real time. The power receiving and transformation system 124 calculates the proportion based on the power supplied from each power source and has data representing the proportion of power supplied from each power source (proportion data described later).

[0041] The Production Management System (PMS) 125 is a system for managing the production plan of items in the factory 120. It has information on the production quantity of items and information (structural information) of the equipment that constitutes the object system 121.

[0042] Database 110 contains reference equipment data 111, reference equipment control data 112, and emission coefficient data 113.

[0043] Reference equipment data 111 is data about the control status and power consumption under load of each piece of equipment in the production system (reference system) that constituted the production of items before the update.

[0044] The reference equipment control data 112 consists of data such as the production quantity of the item during the production of the item by the reference system, the information of each piece of equipment constituting the reference system, the control information of each piece of equipment, and the information of each power supply source.

[0045] Emission coefficient data 113 represents the emission coefficient of carbon dioxide gas per electricity supply source. The carbon dioxide emission coefficient refers to the value of the amount of carbon dioxide gas emitted when generating electricity per unit of electricity from the electricity supply source that powers plant 120. In this embodiment, the value of this emission coefficient is provided in real time from each electricity supply source.

[0046] The information processing device 100 provides a target system emission calculation function 101, a baseline system emission calculation function 102, a reduction contribution calculation function 103, an authentication function 104, and a provision function 105.

[0047] The object system emission calculation function 101 has the following function: calculating the amount of carbon dioxide gas emitted by the production of articles by the object system 121. In this calculation, the total power consumption of the object system 121 as actually measured by multiple sensors 123, the proportion of power supplied by each of the above-mentioned supply sources obtained from the power receiving system 124, and the emission coefficient data 113 obtained from the database 110 are used.

[0048] The baseline system emission calculation function 102 calculates the amount of carbon dioxide gas emitted from the production of goods by the baseline system. This calculation uses baseline equipment data 111, baseline equipment control data 112, and emission coefficient data 113 obtained from database 110.

[0049] The reduction contribution calculation function 103 calculates the reduction contribution of the drive system with drive equipment in the production system of the article in the factory 120 in the reduction of carbon dioxide gas emissions achieved by replacing the reference system with the target system 121. This function calculates the difference between the emissions calculated by the target system emission calculation function 101 and the emissions calculated by the reference system emission calculation function 102 as the reduction contribution.

[0050] The authentication function 104 performs the following function: it authenticates that the information of the object devices 122 constituting the object system 121 in the factory 120 is consistent with that of the constituting devices of the object system 121 managed by the production management system 125. This authentication is used to confirm that there is no impersonation or data tampering of the constituting devices of the object system 121 each time the reduction contribution is calculated, and this authentication is performed during the initial operation when the object system 121 is set up in the factory 120.

[0051] The function 105 provides the following function: it provides the reduction contribution calculated by the reduction contribution calculation function 103 to the providing destination 130. Furthermore, in Figure 1 The diagram illustrates a scenario where a reduction contribution is provided to four destinations 130, but this structure is ultimately illustrative, and the number of destinations 130 providing the reduction contribution can be arbitrary.

[0052] Next, regarding Figure 2 Please provide an explanation. Figure 2 A detailed structural example of the information processing system 200 implementing the present invention is shown.

[0053] The information processing system 200 provides the contribution of the drive system with drive equipment, which is a production system for an article, to the reduction of carbon dioxide emissions achieved by replacing the baseline system with the target system 121. The information processing system 200 is configured to have... Figure 1 The information processing device 100, database 110, and sensor 123 are included.

[0054] Figure 2 The sensor 123 in the summary represents Figure 1 The multiple sensors 123 in the system actually measure the electrical power consumed by the object system 121, which is composed of multiple object devices 122, through the production of the items, i.e., the first electrical power consumed.

[0055] The information processing device 100 includes a first conversion unit 201, an acquisition unit 202, a second conversion unit 203, a calculation unit 204, a provision unit 205, and an authentication unit 206.

[0056] The first conversion unit 201 converts the first power consumption measured by the sensor 123 to obtain the amount of carbon dioxide gas emitted in the power generation with an amount of power equivalent to the first power consumption, i.e., the first emission amount.

[0057] Alternatively, the actual measurement of the first power consumption may not be performed by directly measuring the power consumption of the object system 121 as in the case of sensor 123. For example, the power consumption calculated by a software sensor may also be treated as the first measured power consumption, wherein the software sensor estimates the power consumption of the object system 121 based on the power consumption of associated devices and the power consumption measured by other associated sensors.

[0058] The acquisition unit 202 acquires the electrical energy consumed by the production of the item through the benchmark system, which is the second electrical energy consumed.

[0059] In this embodiment, power consumption data and equipment control data are registered in the database 110. The power consumption data represents the power consumption of each of the multiple reference devices used in the reference system, according to the control content for each reference device. The equipment control data represents the control content performed on each of the multiple reference devices for producing an article by the reference system. The acquisition unit 202 acquires the power consumption data and equipment control data from the database 110, and uses this data to calculate and acquire a second power consumption.

[0060] Alternatively, the acquisition unit 202 may use the control modes of the multiple object devices 122 constituting the object system 121 to derive a power consumption model of the power consumption, and acquire the power consumption corresponding to the control mode of the reference system as a second power consumption.

[0061] That is, for example, a power consumption model of a reference system can be constructed in virtual space using a digital twin method, the environment of the reference system can be built, a second power consumption can be calculated based on the model, and the second power consumption can be acquired by the acquisition unit 202. In this case, the reference power consumption model is composed of a database 110, which registers power consumption data and equipment control data. The power consumption data represents the power consumption of each of the multiple reference devices according to the control content of each reference device for each of the multiple reference devices used in the reference system, and the equipment control data represents the control content performed on each of the multiple reference devices by operating the reference system.

[0062] Alternatively, for example, a power consumption model of the reference system can be created by simulating the operating mode of the object system 121 when the first power consumption is obtained, and the acquisition unit 202 acquires the second power consumption from this model. In this case, the reference power consumption model is composed of a database 110, which registers power consumption data and equipment control data. The power consumption data represents the power consumption of each of the multiple reference devices according to the control content of each reference device for each of the multiple reference devices used in the reference system, and the equipment control data represents the control content performed on each of the multiple reference devices by operating the reference system.

[0063] The second conversion unit 203 converts the second power consumption obtained by the acquisition unit 202 to obtain the amount of carbon dioxide gas emitted during power generation with a power consumption equivalent to the second power consumption, i.e., the second emission amount.

[0064] exist Figure 2 In this structural example, the acquisition unit 202 acquires proportional data and emission coefficient data 113 from the external system 210. The proportional data represents the proportion of electricity supplied by each power source to the installation site (factory 120) of the target system 121, which is supplied from multiple power sources. Furthermore, as described above, the emission coefficient data 113 represents the emission coefficient of carbon dioxide gas for each power source. In this embodiment, the acquisition unit 202 acquires the proportional data from the power receiving and transformation system 124 of the factory 120, and acquires the emission coefficient data 113 from the power generation system of the power supply source via the database 110. That is, the power receiving and transformation system 124 and the power generation system of the power supply source are examples of the external system 210.

[0065] The first conversion unit 201 and the second conversion unit 203 use the proportional data and emission coefficient data 113 acquired by the acquisition unit 202 to convert the amount of electricity consumed. That is, the first conversion unit 201 uses the proportional data and emission coefficient data 113 to convert the first amount of electricity consumed actually measured by the sensor 123 to obtain the first emission amount. In addition, the second conversion unit 203 uses the proportional data and emission coefficient data 113 to convert the second amount of electricity consumed acquired by the acquisition unit 202 to obtain the second emission amount.

[0066] The calculation unit 204 calculates the difference between the first emission amount obtained by the first conversion unit 201 and the second emission amount obtained by the second conversion unit 203 as the reduction contribution.

[0067] The providing unit 205 provides the reduction contribution calculated by the calculation unit 204.

[0068] The information processing system 200 with such a structure uses the object system 121 to calculate the contribution of carbon dioxide reduction by using the actual measured value of the electrical power consumed in the production of the item, and thus can obtain the reduction contribution as an actual value.

[0069] The authentication unit 206 performs authentication on multiple devices that actually constitute the target system 121, verifying that they match the structural information obtained from the external system 210. Furthermore, the structural information is used to identify the devices constituting the target system 121. In this embodiment, the authentication unit 206 obtains the structural information from the production management system 125. That is, the production management system 125 is also an example of the external system 210.

[0070] Figure 2 The information processing system 200 illustrated above includes the above-mentioned components. Furthermore, among the functions provided by the information processing device 100, the target system emission calculation function 101 is provided by the first conversion unit 201, the baseline system emission calculation function 102 is provided by the second conversion unit 203, and the reduction contribution calculation function 103 is provided by the calculation unit 204. Additionally, the authentication function 104 is provided by the authentication unit 206, and the provision function 105 is provided by the provision unit 205.

[0071] Alternatively, the first conversion unit 201 may convert the power consumption per unit of production of the item, calculated based on the first power consumption, to obtain the first emission amount based on the production volume of the item by the object system 121. Alternatively, the second conversion unit 203 may convert the power consumption per unit of production of the item, calculated based on the second power consumption, to obtain the second emission amount based on the production volume of the item by the reference system. In this case, the calculation unit 204 calculates the difference between the first emission amount obtained by the first conversion unit 201 and the second emission amount obtained by the second conversion unit 203 as the reduction contribution per unit of production of the item.

[0072] Next, use Figure 3 The data structure of each registered data in database 110 is explained.

[0073] As described above, the database 110 contains reference equipment data 111, reference equipment control data 112, and emission coefficient data 113.

[0074] Reference device data 111 is an example of power consumption data, which is obtained by establishing a correspondence between the model name, type name, and manufacturing number of each reference device constituting the reference system and the power consumption. Furthermore, regarding power consumption, the value of each control logic is registered, representing the control content (e.g., the device's operating mode) for the reference device.

[0075] Reference equipment control data 112 is an example of equipment control data. It is data obtained by establishing a correspondence between the model name and type name of each reference equipment constituting the reference system and the control logic. Furthermore, the control logic records information used to identify the control content applied to each reference equipment during the production of an article by the reference system. By establishing a correspondence between the reference equipment control data 112 and the reference equipment data 111 using the model name and type name information and the control logic information, the power consumption of each reference equipment when the reference system produces an article is obtained.

[0076] The emission coefficient data 113 is obtained by establishing a correspondence between the name of the power supply source that supplies electricity to the plant 120 and the aforementioned emission coefficient of that power supply source.

[0077] Next, use Figure 4 An example of the hardware structure of the information processing device 100 will be described.

[0078] The information processing device 100 includes components such as a CPU 301, a memory 302, an input device 303, an output device 304, an auxiliary storage device 305, an object device I / F 306, and a communication I / F 307. These components are all connected to an internal bus 308, enabling data exchange between them. Furthermore, "CPU" is short for Central Processing Unit. Additionally, "I / F" is short for Interface.

[0079] CPU 301, for example, controls the various hardware components of information processing device 100 by executing a prescribed program using memory 302, thereby providing the various functions of information processing device 100.

[0080] The memory 302 is, for example, a semiconductor memory, comprising RAM and ROM regions. Furthermore, "RAM" is short for Random Access Memory, and "ROM" is short for Read Only Memory.

[0081] The input device 303 is, for example, a keyboard for indicating input, a pointing device, etc.

[0082] Output device 304 is a display device used for outputting various types of information.

[0083] The auxiliary storage device 305 is a non-volatile storage device, such as flash memory.

[0084] The object device I / F 306 sends and receives various data with the object device 122 according to the instructions sent from the CPU 301. The data received by the object device I / F 306 from the object device 122 also includes data on the power consumption of the object device 122 as actually measured by the sensor 123.

[0085] According to the instructions sent from the CPU 301, the communication I / F 307 sends and receives various data with the database 110, the power receiving system 124, the production management system 125, the destination provider 130, etc. via a communication network not shown.

[0086] The information processing device 100 has the hardware structure described above.

[0087] Next, the various processes performed by the information processing device 100 will be described. These processes are implemented by the CPU 301 executing a prescribed program.

[0088] First, let's explain the authentication process. Figure 5 This is a flowchart illustrating an example of the authentication process.

[0089] The authentication process is a process that verifies the consistency between the multiple devices that actually constitute the object system 121 and the structural information obtained from the external system 210. It is a process used to provide the function of the authentication unit 206.

[0090] When it begins Figure 5 During the processing, firstly, the following processing is performed in S101: obtain the structural information of the object system 121 from the production management system 125.

[0091] Next, in S102, the following process is performed: an identification information transmission request is sent to each object device 122 constituting the object system 121 set in the factory 120.

[0092] Assume that the target device 122 has the following function: when it receives the identification information transmission request, it returns the identification information containing its own model name, model name and manufacturing number to the source of the request.

[0093] Next, in S103, the following process is performed: receiving identification information sent from the target device 122, and in the following S104, determining whether identification information has been received. In this determination process, if it is determined that identification information has been received (when the determination result is "yes"), the process proceeds to S107.

[0094] On the other hand, in the determination process of S104, when it is determined that no identification information has been received (when the determination result is "no"), the process is advanced to S105, and the following process is performed: determining whether a predetermined time has elapsed in the state of not receiving identification information.

[0095] In the process of S105, when the determination process of S104 first becomes "No", a timer (not shown) is started to count down. When the timer has counted for a specified time, the determination result is changed from "No" to "Yes". In addition, if the determination process of S104 becomes "Yes" after the timer starts counting down, the timer is stopped and reset.

[0096] In the determination process of S105, when it is determined that a predetermined time has elapsed (when the determination result is "yes"), the process proceeds to S106, where the following process is performed: the output device 304 outputs a message indicating authentication failure. After that, the authentication process ends.

[0097] In S107, the following process is performed: determining whether the received identification information is appropriate. This process compares the model name, serial number, and manufacturing number information contained in the identification information with the equipment information contained in the structural information obtained from the production management system 125 through the process in S101. If the comparison result is consistent, the identification information is determined to be appropriate; otherwise, the identification information is determined to be inappropriate.

[0098] In the determination process of S107, if the identification information is determined to be appropriate (the determination result is "yes"), the process proceeds to S108. On the other hand, in the determination process of S107, if the identification information is determined to be inappropriate (the determination result is "no"), the process proceeds to S106, where the output device 304 outputs information indicating authentication failure, and then the authentication process ends.

[0099] In S108, the following process is performed: determining whether identification information has been received from all devices represented by the structure information of the object system 121. In this determination process of S108, if it is determined that identification information has been received from all devices (if the determination result is "yes"), the process proceeds to S109. On the other hand, in the determination process of S108, if it is determined that there are still devices that have not received identification information (if the determination result is "no"), the process returns to S103, and the above-mentioned process is performed again.

[0100] In the determination process of S108, if the structural information obtained from the production management system 125 contains information about a device that has not been compared with the identification information received through the process of S103, the determination result is "No".

[0101] In S109, the following process is performed: the output device 304 outputs a message indicating successful authentication. Afterward, the authentication process ends.

[0102] The above processing is Figure 5 The authentication process is illustrated in the example.

[0103] Furthermore, in the processing of S106, the information of the device determined to be inappropriate in the determination processing of S107, and the information of the device that was not compared with the identification information received in the processing of S103, may be output together with the information indicating authentication failure or as the information indicating authentication failure.

[0104] Next, the calculation and processing of the reduction contribution will be explained. Figure 6 This is a flowchart illustrating an example of the process for calculating the reduction contribution.

[0105] The reduction contribution calculation process is as follows: calculating and providing the reduction contribution of the drive system with drive equipment in the production system of the article in the reduction of carbon dioxide gas emissions achieved by replacing the reference system with the object system 121.

[0106] When it begins Figure 6 During the processing, firstly, a baseline system emission calculation process is performed in S201. This process involves calculating the amount of carbon dioxide gas emitted from the production of articles by the baseline system. Details of this process will be described later.

[0107] Next, in S202, the emission calculation process for the object system is performed. This process involves calculating the emission of carbon dioxide gas produced by the object system 121. Details of this process will also be described later.

[0108] In S203, the following process is performed: The reduction contribution is calculated based on the carbon dioxide emissions of the reference system calculated by the process in S201 and the carbon dioxide emissions of the target system 121 calculated by the process in S202. In this process, the reduction contribution is calculated by subtracting the carbon dioxide emissions of the reference system (second emission) from the carbon dioxide emissions of the target system 121 (first emission). This process is for providing the function of the calculation unit 204.

[0109] In S204, the following processing is performed: a request to provide the calculated reduction contribution is received; in the following S205, the following processing is performed: it is determined whether the request to provide has been received. The request to provide is a request sent from the providing destination 130.

[0110] In the determination process of S205, when it is determined that a provision request has been received (when the determination result is "yes"), the process proceeds to S206, where the following process is performed: the reduction contribution calculated by the process of S203 is sent to the provision destination 130, which is the sending source of the received provision request. The process of S206 is for providing the function of the provision unit 205.

[0111] After processing in S206, the process returns to S202, repeating the processing after the calculation of the system emissions.

[0112] On the other hand, in the determination process of S205, if it is determined that no request has been received (when the determination result is "no"), the processing of S206 is skipped and the processing is returned to S202.

[0113] The above processing is Figure 6 The example illustrates the calculation and processing of the reduction contribution.

[0114] In addition, Figure 6 In the processing, the reduction contribution is sent to the delivery destination 130, which is the sending source, in response to the receipt of the delivery request. However, it can also be set so that whenever a new reduction contribution is calculated (regardless of whether a delivery request is received), the calculated reduction contribution is sent to the delivery destination 130.

[0115] Next, regarding Figure 6 The details of the S201 processing in the calculation of reduction contribution, namely the baseline system emission calculation processing, will be explained. Figure 7 This is a flowchart illustrating an example of the processing steps involved in calculating emissions from a baseline system.

[0116] When it begins Figure 7 During processing, firstly, in S211, the following process is performed: reference device data 111 and reference device control data 112 are obtained from database 110. Next, in S212, the following process is performed: using the data obtained through the processing in S211, the electrical power consumed by the reference system through the production of items in the reference system (second electrical power consumption) is calculated.

[0117] In the S212 process, firstly, for each reference device shown in the reference device control data 112, the electrical power consumed when the reference device operates under the control logic applied during the production of the item in the reference system is obtained from the reference device data 111. Then, the electrical power consumed by each reference device is summed, and the sum is used as the calculation result of the second electrical power consumption.

[0118] Next, in S213, the following processing is performed: the above-mentioned proportional data, that is, the data representing the proportion of the power supply source, is obtained from the power receiving system 124, and in the following S214, the following processing is performed: emission coefficient data 113 is obtained from the database 110.

[0119] The processes described above, S211 to S214, are processes used to provide the functions of the acquisition unit 202.

[0120] Next, in S215, the following process is performed: using the proportion data and emission coefficient data 113 obtained through the processes in S212 and S213, the second power consumption calculated through the process in S212 is converted into carbon dioxide emissions. This process is for providing the function of the second conversion unit 203.

[0121] In the process of S215, firstly, for each power supply source shown in the emission coefficient data 113, the emission coefficient for that power supply source is multiplied by the proportion of that power supply source, as represented by the proportional data. Then, by summing the values ​​obtained for each power supply source, the emission coefficient in plant 120, i.e., the carbon dioxide emission per unit of electricity consumed, is calculated. The emission coefficient in plant 120 thus obtained is multiplied by the second power consumption calculated through the process of S212, thereby calculating the carbon dioxide emission (second emission) for the reference system.

[0122] Once the carbon dioxide emissions of the reference system are obtained through the process described in S215 above, the reference system emission calculation process ends, and the process is then returned to... Figure 6 The calculation and processing of the reduction contribution.

[0123] The above processing is Figure 7 The example shows the calculation and processing of emissions from the baseline system.

[0124] Next, regarding Figure 6 The details of the S202 processing in the calculation of the reduction contribution, namely the calculation of the emission of the target system, will be explained. Figure 8 This is a flowchart illustrating an example of the process involved in calculating emissions from an object system.

[0125] When it begins Figure 8 During the processing, firstly, the following processing is performed in S221: the actual measured value of the power consumed by each object device 122 is obtained from the sensor 123 respectively installed on each object device 122 constituting the object system 121.

[0126] Next, in S222, the following process is performed: the power consumption data obtained from each sensor 123 through the processing in S221 are summed to calculate the total power consumption of the target system 121 (first power consumption).

[0127] Next, in S223, the following processing is performed: the aforementioned proportional data, i.e., data representing the proportion of power supply sources, is obtained from the power receiving and transformation system 124. Then, in S224, the following processing is performed: emission coefficient data 113 is obtained from the database 110. These processes in S223 and S224 are for providing the functions of the acquisition unit 202.

[0128] Next, in S225, the following process is performed: using the proportion data and emission coefficient data 113 obtained through the processes in S222 and S223, the first power consumption calculated through the process in S222 is converted into carbon dioxide emissions. This process is for providing the function of the first conversion unit 201.

[0129] In the process of S225, firstly, for each power supply source shown in the emission coefficient data 113, the emission coefficient for that power supply source is multiplied by the proportion of that power supply source, as represented by the proportional data. Then, by summing the values ​​obtained for each power supply source, the emission coefficient in plant 120, i.e., the carbon dioxide emission per unit of electricity consumed, is calculated. The emission coefficient in plant 120 thus obtained is multiplied by the first power consumption calculated by the process of S222, thereby calculating the carbon dioxide gas emission (first emission) for the target system 121.

[0130] When the carbon dioxide emissions of object system 121 are obtained through the above-described S225 process, the object system emission calculation process ends, and then the process is returned to... Figure 6 The calculation and processing of the reduction contribution.

[0131] The above processing is Figure 8 The example above illustrates the calculation and processing of emissions from the system.

[0132] By performing the aforementioned processes by the information processing device 100, it is possible to provide the contribution of the drive system with drive equipment in the production system of the article to the reduction of carbon dioxide emissions achieved by replacing the reference system with the target system 121.

[0133] The disclosed embodiments and their advantages have been described in detail above, but those skilled in the art can make various changes, additions, and omissions without departing from the scope of the invention as expressly stated in the claims.

[0134] For example, a target value for reducing the contribution can be preset and stored in the storage area of ​​the information processing device 100. In this case, it can also be set to determine if the decision is successful. Figure 6 In the illustrated reduction contribution calculation process, step S203 determines whether the calculated reduction contribution meets the target value. If it is determined that the reduction contribution does not meet the target value, the output device 304 outputs a notification indicating that the reduction contribution does not meet the target value. Alternatively, if it is determined that the reduction contribution does not meet the target value, step S206 may send a message indicating that the reduction contribution does not meet the target value, either along with or in lieu of the calculated reduction contribution.

[0135] Alternatively, for example, an appropriate range for the power consumption of the target device 122 can be preset and stored in the storage area of ​​the information processing device 100. In this case, it can also be set to determine in Figure 8 In the S221 process illustrated in the example, if the actual measured value of the power consumed by the object device 122 obtained from the sensor 123 meets the appropriate range, and if it is determined that it does not meet the range, the output device 304 outputs a notification of the main point.

[0136] Alternatively, for example, it can also be set to pass through Figure 7 The second power consumption calculated by the process of S212 in the illustrated process, and through Figure 8 The first power consumption calculated in process S222 of the illustrated process is used as the power consumption per unit of product production. That is, for example, in process S212, the total power consumption of each reference device is divided by the product production quantity of the reference system consuming that total power, and the result is used as the calculation result of the second power consumption. Furthermore, in process S222, the total power consumption obtained from each sensor 123 is divided by the product production quantity of the target system 121 consuming that total power, and the result is used as the calculation result of the first power consumption. By doing so, through... Figure 6 The reduction contribution calculated by process S203 in the illustrated process becomes the reduction contribution for each production quantity of the item. Furthermore, the unit for the production quantity of the item can be, for example, a batch unit.

[0137] In addition, as another implementation of the drive system, there is an article conveying system. For example... Figure 1 As shown, the information processing device 100 is connected to the database 110. The information processing device 100 calculates the contribution of the drive system with drive equipment, which is a conveying system for goods in a factory or warehouse, to the reduction of carbon dioxide emissions achieved through updates, and provides this information to the destination 130.

[0138] Furthermore, in the above embodiments, the information processing system 200 was described as a drive system related to the production of goods, but the information processing system 200 can also be applied as a goods transportation system. In the goods transportation system, "goods production" can be replaced with "goods transportation," and "Production Management System (PMS)" can be replaced with "Point of Distribution System (PDS)" and "Warehouse Management System (WMS)," etc.

[0139] Furthermore, in the above embodiments, examples of calculating the reduction contribution for each production quantity of items and the reduction contribution per batch were described. Here, when the information processing system 200 is applied as a drive system related to transportation, the reduction contribution required to transport a specific number of items and the reduction contribution required to transport one item can also be calculated. Additionally, as an example of a business operation, in the automation of the operation of sorting, retrieving, and moving items from a factory site or warehouse to a designated location (picking work), the reduction contribution of the drive system with drive equipment, which is the item transportation system, is calculated in terms of the reduction of carbon dioxide emissions achieved through updates. In this case, the drive equipment consists of inverters, conveyors, transport robots, Automated Guided Vehicles (AGVs), etc.
