[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. [Example 1] First, a CO2 emission reduction policy generating device according to a first embodiment of the present invention will be described.
[0011] <Configuration> 1 is a diagram showing an example of the configuration of a CO2 emission reduction policy generation device 1 according to this embodiment. The CO2 emission reduction policy generation device 1 is an information processing device that proposes a policy for reducing CO2 emissions based on the amount of CO2 emissions emitted by conventional methods and the target CO2 emission amount, for example, in on-site construction work using equipment such as construction machinery.
[0012] The CO2 emission reduction policy generating device 1 includes a storage unit 100, a memory 200, a calculation unit 300, an input unit 400, an output unit 500, and a communication unit 600.
[0013] The storage unit 100 is configured, for example, by a ROM (Read Only Memory), and stores theoretical data 110 of fuel or power consumption for the equipment to be introduced, actual measurement data 111 of the amount of fuel or power consumed in predetermined work for the conventional equipment, data 120 of CO2 emissions per fuel or power consumption unit, budget data 130 based on the budget for introducing the equipment, and price data 140 based on the price when each equipment is introduced. Note that the theoretical data 110 of fuel or power consumption for the equipment to be introduced and actual measurement data 111 of the amount of fuel or power consumed in predetermined work for the conventional equipment correspond to the equipment data in the claims.
[0014] The memory 200 is configured by, for example, a RAM (Random Access Memory), and programs for various calculations are loaded onto the memory 200 and executed by the calculation unit 300 to perform various functions.
[0015] The calculation unit 300 is configured by, for example, a CPU (Central Processing Unit). The input unit 400 is configured by, for example, a keyboard. The output unit 500 is configured by, for example, a display. The input unit 400 and the output unit 500 may be integrated into, for example, a display-type interface equipped with a touch panel. The communication unit 600 is configured to be connectable to a communication network and is responsible for sending and receiving data to and from external devices.
[0016] <Processing> Fig. 2 is a flowchart showing the process flow executed by the CO2 emission reduction policy generation device to present options for equipment to be introduced. The process shown in this figure is executed, for example, in the phase of formulating a future construction plan, when the CO2 emissions of equipment used in past on-site construction work are known.
[0017] First, in the process flow for presenting options for equipment to be introduced, the CO2 emission reduction policy generation device determines whether actual measurements of fuel or power consumption are known for the conventional equipment (S201). Next, if the actual measurements are unknown (NO), the device calculates the estimated CO2 emissions estimated to be emitted throughout the entire construction plan from theoretical fuel or power consumption data 110 for the equipment to be introduced. If the actual measurements are known (YES), the device calculates the estimated CO2 emissions estimated to be emitted throughout the entire construction plan from actual fuel or power consumption data 111 for the conventional equipment and CO2 emission data 120 per unit of fuel or power consumption (S202). Specifically, the estimated CO2 emissions can be calculated by, for example, multiplying the theoretical fuel or power consumption data 110 for the equipment to be introduced by the CO2 emission data 120 per unit of fuel or power consumption, or by multiplying the actual measurement data 111 for the fuel or power consumption of the conventional equipment consumed in a specified task by the CO2 emission data 120 per unit of fuel or power consumption.
[0018] Next, the target CO2 emission amount for the construction plan to be executed is input (s203), and it is determined whether the estimated CO2 emission amount is greater than the target CO2 emission amount (s204). If the estimated CO2 emission amount is greater than the target CO2 emission amount (YES), the difference between the two is calculated (s205). The target CO2 emission amount may be stored in the storage unit 100 in advance.
[0019] Next, budget data 130 based on the budget for introducing the equipment and price data 140 based on the price of each piece of equipment are input, and options for equipment to be introduced that fall within the specified budget are presented (S206). That is, in this step, all options for equipment that meet the budget are presented first, rather than focusing on the amount of CO2 emission reduction. For the person in charge of on-site construction, there is a target CO2 emission reduction that needs to be achieved, but there is also a limit to the budget that can be spent on measures to reduce CO2 emissions (such as introducing electric construction machinery). Therefore, by presenting a policy that falls within the budget that can be spent on the policy, the feasibility of the policy can be improved.
[0020] Next, it is determined whether or not an electric construction machine is being used as the main equipment for on-site construction (S207). If an electric construction machine is not being used (NO), the differential CO 2Estimated emissions The system presents options such as electric construction machinery as equipment that should be introduced to reduce CO2 emissions (S208). The person in charge of the on-site construction considers the presented options, taking into account the budget and the CO2 emissions that will be reduced by the introduction, and decides on the equipment to be introduced, including whether to purchase or lease it.
[0021] If an electric construction machine has already been installed as the main equipment (YES), options for sub-equipment to be installed within the specified budget are presented (S209). Then, it is determined whether a power bank has been installed as a sub-equipment (S210). A power bank is a large storage battery that can be mounted on construction machinery. This eliminates the need to move the construction machinery to a power source installed on-site each time it is charged, thereby reducing CO2 emissions by the same amount. Therefore, if a power bank has not been installed as a sub-equipment (NO), the option of a power bank is presented as an option for equipment to be installed (S211). If a power bank has been installed as a sub-equipment (YES), options for equipment to be installed related to fuel or power consumption measurement devices for specific tasks are presented as options. Specifically, these are vibration sensors and temperature sensors for checking the operating status of the construction machinery's drive components, and sensors with lower CO2 emissions are presented as options.
[0022] In the above example, EV construction machinery was used as the main equipment and a power bank as the sub-equipment, but other examples include drones for site inspection as the main equipment and solar panels for generating electricity as the sub-equipment.
[0023] In summary, the CO2 emission reduction policy generation device 1 according to the present invention includes a storage unit 100 and a calculation unit 300. The storage unit 100 stores equipment data (110, 111) based on the equipment used in the work and unit consumption data 120, which is set for each equipment and is the amount of CO2 emission caused by the unit consumption of fuel or electricity. The calculation unit 300 calculates an estimated amount of CO2 emission that is estimated to be caused by a predetermined work based on the equipment data and the unit consumption data, and when the estimated CO2 emission is greater than a predetermined target CO2 emission, calculates a differential CO2 emission estimated amount, which is the difference between the target CO2 emission and the estimated CO2 emission, and calculates the differential CO2 emission. 2Estimated emissions Based on equipment data, we suggest equipment that should be introduced to reduce this.
[0024] More specifically, the calculation unit 300 calculates the estimated CO2 emissions based on the fuel or electricity consumption (110, 111) consumed by each device when it performs a specified task and the unit consumption data 120 corresponding to each device.
[0025] Furthermore, the memory unit 100 further stores budget data 130 based on the budget for introducing the equipment and price data 140 based on the price if each piece of equipment is introduced, and when the estimated CO2 emissions are greater than the target CO2 emissions, the calculation unit 300 presents options for equipment to be introduced so as to fall within a specified budget based on the budget data 130 and the price data 140.
[0026] As described above, according to this embodiment, by presenting options for equipment that can reduce CO2 emissions based on the difference between the estimated CO2 emissions and the target CO2 emissions, the parties involved in the on-site construction work can understand and implement what changes should be made to equipment, etc. in order to reduce CO2 emissions.
[0027] [Example 2] Next, a description will be given of a CO2 emission reduction policy generating device according to a second embodiment of the present invention. Note that, in the following, a description of the same configuration as in the first embodiment will be omitted.
[0028] <Configuration> 3 is a diagram illustrating an example of the configuration of a CO2 emission reduction policy generation device 1 according to Example 2. The CO2 emission reduction policy generation device 1 according to this example differs from Example 1 in that in this example, a memory unit 100 of the CO2 emission reduction policy generation device 1 further stores data on the amount of fuel or electricity consumed so far (amount already consumed) 150, data on the amount of work already completed (completed work data) 160, data on the amount of work remaining (remaining work data) 170, and data on available operation time 180.
[0029] <Processing> 4 is a flowchart showing the process of presenting options for equipment to be introduced, which is executed by the CO2 emission reduction policy generation device in this embodiment. The process shown in this figure is executed, for example, in the phase of re-planning the remaining construction work plan when the CO2 emissions so far of the equipment currently being used in on-site construction work that has already started are known.
[0030] The CO2 emission reduction policy generation device first inputs data 150 on the amount of fuel or electricity consumed so far and data 160 on the amount of work already completed for equipment currently being used in on-site construction work that has already begun, and calculates the amount of fuel or electricity consumed per unit of work (s601).
[0031] Next, the amount of fuel or power expected to be consumed when the remaining construction plan is carried out is calculated from the data 170 relating to the amount of fuel or power consumed per unit work amount and the remaining work amount (s602).
[0032] Next, the estimated CO2 emissions that are estimated to be emitted throughout the entire construction plan are calculated from the estimated fuel or electricity replenishment amount mentioned above, the fuel or electricity consumption data 150 so far, and the CO2 emissions data 120 per fuel or electricity unit (s603).
[0033] Next, the target CO2 emissions are calculated (s604), and the difference between the calculated target CO2 emissions and the estimated CO2 emissions is calculated (s605). Then, it is determined whether the estimated CO2 emissions are greater than the target CO2 emissions (s606). If the estimated CO2 emissions are greater than the target CO2 emissions (YES), budget data 130 based on the budget for introducing the equipment and price data 140 based on the price of each equipment are input, and options for equipment to be introduced and its usage methods are presented so as to fit within the specified budget (s607).
[0034] Then, an operation plan and a power supply method that can reduce the estimated differential CO2 emission amount are presented (S608). Specifically, as in the first embodiment, the replacement of the main equipment and the sub-equipment is proposed, and in this embodiment, a change in the method of using the equipment is also proposed. The reason why the method of using the equipment is considered only in this embodiment is that the processing in the first embodiment is performed at the planning stage of the construction plan as described above, and it is practically impossible to consider a change in the method of using the equipment at that point.
[0035] Furthermore, if the estimated CO2 emissions are less than the target CO2 emissions (NO) in (s606), the data 180 on available operating time is used to present an equipment operation plan and power supply method that will complete the remaining work volume in the shortest time possible while keeping the estimated CO2 emissions within the target CO2 emissions (s609). For the person in charge of on-site construction, the construction period is a very important factor that affects the trust of the on-site construction client, so by presenting a policy that encourages both the target CO2 emissions and adherence to the construction period, a more realistic work policy can be formulated.
[0036] In summary, in the CO2 emission reduction policy generation device according to this embodiment, the memory unit 100 further stores an already consumed amount 150, which is the amount of fuel or electricity consumed up to now, completed work data 160, which is the amount of work that has already been completed, and remaining work data 170, which is the amount of work that remains. The calculation unit 300 calculates a consumption per unit of work, which is the amount of fuel or electricity consumed per unit of work, based on the already consumed amount 150 and the completed work data 160, calculates an estimated consumption, which is the amount of fuel or electricity that is estimated based on the consumption per unit of work and the remaining work data 170, calculates an estimated CO2 emission amount based on the already consumed amount, the estimated consumption amount, and the basic unit data, and calculates an estimated CO2 emission amount if the estimated CO2 emission amount is less than the target CO2 emission amount. Larger In this case, the system will present the options for equipment to be replaced and how to use it so that it fits within the specified budget.
[0037] More specifically, the calculation unit 300 calculates the amount of CO2 emissions during construction from the amount of consumption already achieved 150 and the basic unit data, calculates the amount of CO2 emissions per unit of work by dividing the amount of CO2 emissions during construction by the completed work data 160, multiplies the amount of CO2 emissions per unit of work by the remaining work data 170, and adds it to the amount of CO2 emissions during construction to calculate the estimated amount of CO2 emissions.
[0038] The calculation unit 300 also calculates the estimated difference in CO2 emissions, which is the difference between the target CO2 emissions and the estimated CO2 emissions, and presents again options for devices to be introduced and their usage methods based on the estimated difference in CO2 emissions.
[0039] Examples of screens output by this embodiment are shown in FIGS. Screen 700 shown in FIG. 5 displays the current status of CO2 emissions at a certain site A. Screen 700 includes graph 701 showing the trend in CO2 emissions up to that point. This graph reveals that the construction plan was changed on July 14, resulting in predicted actual values exceeding the planned values from August onward. Graph 702, which shows the relationship between CO2 emissions and planned values, reveals that the target CO2 emissions are 100,000 kg and the current total emissions are 75,000 kg. Displays 703, 704, and 705 show CO2 emissions by work process and type of construction equipment. The display period can be changed by selecting calculation period switch button 707. Selecting reduction simulation button 706 takes the user to the CO2 reduction simulation screen shown in FIG. 6.
[0040] Screen 800 shown in Fig. 6 is a screen that displays a reduction simulation based on the selected plan. In Fig. 6, the "large reduction" plan is selected, and this plan can be switched by selecting switch button 805. Screen 800 displays graph 801 that compares the emissions when the selected plan is implemented, and by referring to this graph, it is possible to confirm the change in emissions due to the plan selection. In addition, displays 802, 803, and 804 respectively show the specific content of the plan, the expected impact, and the analysis results. The content of these changes as the plan is changed as appropriate.
[0041] The site manager or the like considers the presented plans while taking into account the budget and the target CO2 emission reduction amount, while referring to the screens shown in Figures 5 and 6. Note that the screens in Figures 5 and 6 are example screens in this embodiment in which the construction plan is re-drafted during construction, but similar screens are also output in Example 1 in which the construction plan is drafted before the start of construction.
[0042] As described above, this embodiment also presents options for equipment that can reduce CO2 emissions based on the difference between estimated CO2 emissions and target CO2 emissions, enabling the parties involved in on-site construction to understand and implement what changes should be made to equipment, etc. in order to reduce CO2 emissions.
[0043] According to the embodiment of the present invention described above, the following advantageous effects are achieved. (1) A CO2 emission reduction policy generation device according to the present invention includes a storage unit and a calculation unit. The storage unit stores equipment data based on equipment used in a task and unit consumption data set for each piece of equipment, which is CO2 emissions resulting from unit consumption of fuel or electricity. The calculation unit calculates estimated CO2 emissions estimated to result from a predetermined task based on the equipment data and unit consumption data. If the estimated CO2 emissions are greater than a predetermined target CO2 emissions, the calculation unit calculates a differential CO2 emission estimate, which is the difference between the target CO2 emissions and the estimated CO2 emissions. 2Estimated emissions Based on equipment data, we suggest equipment that should be introduced to reduce this.
[0044] By adopting the above configuration, it is possible to provide a CO2 emission reduction policy generation device that enables the parties involved in on-site construction to understand and implement what changes should be made to equipment, etc. in order to reduce CO2 emissions based on the visualized CO2 emissions.
[0045] (2) The calculation unit calculates the estimated CO2 emissions based on the amount of fuel or electricity consumed by the equipment when it performs a predetermined operation and the unit consumption data corresponding to the equipment.
[0046] (3) The memory unit further stores price data based on the price of introducing the equipment and budget data based on the budget for introducing the equipment, and when the estimated CO2 emissions are greater than the target CO2 emissions, the calculation unit presents options for equipment to be introduced so as to be within a specified budget based on the price data and the budget data.
[0047] (4) The memory unit further stores an already consumed amount, which is the amount of fuel or electricity consumed up to now, completed work data relating to the amount of work already completed, and remaining work data relating to the amount of work remaining. The calculation unit calculates a consumption per unit of work, which is the amount of fuel or electricity consumed per unit of work, based on the already consumed amount and the completed work data, calculates an estimated consumption, which is the amount of fuel or electricity expected to be consumed based on the consumption per unit of work and the remaining work data, calculates an estimated CO2 emission amount based on the already consumed amount, the estimated consumption amount, and the basic unit data, and calculates an estimated CO2 emission amount if the estimated CO2 emission amount is greater than the target CO2 emission amount. Larger In this case, the system will present the options for equipment to be replaced and how to use it so that it fits within the specified budget.
[0048] (5) The calculation unit calculates the amount of CO2 emissions during construction from the amount already consumed and the basic unit data, calculates the amount of CO2 emissions per unit of work by dividing the amount of CO2 emissions during construction by the data on completed work, multiplies the amount of CO2 emissions per unit of work by the remaining work data, and adds this to the amount of CO2 emissions during construction to calculate the estimated amount of CO2 emissions.
[0049] (6) The calculation unit calculates the difference between the target CO2 emission amount and the estimated CO2 emission amount, which is the difference between the target CO2 emission amount and the estimated CO2 emission amount, and again presents options for the equipment to be introduced and its usage method based on the calculated difference CO2 emission amount.
