Description

Technical Field

[0001] This invention relates to the field of building carbon emission measurement technology, specifically to a method for dynamic tracking and itemized accounting of construction carbon emissions for mobile temporary facilities. Background Technology

[0002] Construction typically requires the erection of temporary power supply facilities, temporary power distribution facilities, temporary buildings, temporary lighting facilities, and temporary processing facilities. As the construction phase, work area, and tasks change, some temporary facilities need to be relocated between different construction areas, requiring the assistance of hoisting equipment, transport vehicles, forklifts, dismantling and rewiring equipment to complete the relocation work. The electricity, fuel, or gas consumption generated during the operation and relocation of these facilities and auxiliary equipment are all included in the activity data related to construction carbon emission accounting.

[0003] Existing methods for calculating carbon emissions from construction typically use construction projects, construction areas, construction tasks, or sub-projects as accounting units. They collect energy consumption data from facilities or equipment using energy metering devices and assign this data to corresponding accounting accounts based on equipment identification, equipment type, or the construction area. Carbon emissions are then calculated by combining this data with the emission factors for the appropriate energy type. Some existing methods also use positioning devices to obtain the location coordinates of construction facilities or equipment and update the energy consumption data based on the spatial correspondence between these coordinates and the construction area.

[0004] However, the relocation of mobile temporary facilities is not instantaneous. During the process of the mobile temporary facilities leaving the original construction area, entering the target construction area, and resuming stable operation, location drift, short-term location fluctuations, and location data interruptions may cause misjudgments of the relocation or premature switching of accounting accounts. If the accounting account is switched based solely on a single location coordinate or construction area boundary, the energy consumption before and after the relocation confirmation may be incorrectly attributed to the original construction task or the target construction task.

[0005] Meanwhile, energy consumption during the relocation of mobile temporary facilities may include not only the energy consumption generated by the mobile temporary facilities themselves, but also the energy consumption generated by auxiliary equipment such as hoisting, transportation, dismantling, and rewiring. Existing methods typically record the energy consumption data of mobile temporary facilities and auxiliary equipment separately, lacking a unified data association basis to represent a complete relocation process, making it difficult to determine the effective relocation operation time of auxiliary equipment and its service targets. When the same auxiliary equipment serves multiple mobile temporary facilities, there may also be problems such as auxiliary equipment energy consumption being repeatedly included in multiple facilities, unclear allocation basis, or some relocation energy consumption not being collected. Summary of the Invention

[0006] The technical problem this invention aims to solve is: how to collaboratively process continuous location data, energy consumption data, and operational status data of mobile temporary facilities to accurately identify the migration process and time boundaries of these facilities, and to utilize the same migration event to uniformly constrain the switching of accounting accounts, the identification of the migration energy consumption of the mobile temporary facility itself, and the association and allocation of the migration energy consumption of auxiliary equipment. This reduces incorrect energy consumption attribution caused by location drift or migration confirmation delays, avoids duplicate collection or omission of shared auxiliary equipment energy consumption, and achieves dynamic tracking and itemized accounting of carbon emissions from the construction of mobile temporary facilities. To this end, this invention provides a method for dynamic tracking and itemized accounting of construction carbon emissions for mobile temporary facilities, ensuring consistency in the migration status of mobile temporary facilities, accounting account switching time, migration energy consumption identification range, and auxiliary equipment energy consumption attribution, thereby improving the accuracy, completeness, and traceability of the construction carbon emission itemized accounting results.

[0007] This invention is achieved through the following technical solution:

[0008] A method for dynamic tracking and itemized accounting of carbon emissions from the construction of mobile temporary facilities includes:

[0009] By setting up positioning devices, energy metering devices, and operation status acquisition interfaces on the target mobile temporary facilities, the equipment identification, location coordinates, sampling time, energy consumption, and operation status of the target mobile temporary facilities are collected, and the correspondence between construction area, construction task, sub-item project, and carbon emission accounting account is established.

[0010] The migration status of the target mobile temporary facility is determined based on its continuous location trajectory, displacement distance, duration, and regional status. When the migration status is a suspected migration status, the energy consumption whose attribution is yet to be determined is included in the energy consumption to be confirmed. The suspected migration status is a state in which the target mobile temporary facility has continuously deviated from its original stable area before migration and has reached the preset suspected migration judgment condition, but its cumulative displacement, continuous deviation time, and consistency of movement direction have not yet simultaneously met the corresponding migration confirmation condition.

[0011] When a target mobile temporary facility in the suspected migration state meets the migration confirmation conditions, a migration event ID corresponding to this migration process is established, and the migration start time and migration completion time are determined according to the migration state to form a migration event time window.

[0012] Before the migration completion time, the normal operating energy consumption, excluding the energy consumption to be confirmed and the migration energy consumption, shall be attributed to the original accounting account corresponding to the previous migration. After the migration completion time, the normal operating energy consumption shall be attributed to the target accounting account corresponding to the previous migration.

[0013] Based on the migration event time window and the operating status of the target mobile temporary facility, the migration energy consumption generated by the target mobile temporary facility itself is identified, and based on the operating data of the auxiliary equipment participating in this migration process, the migration energy consumption of the auxiliary equipment is associated with the migration event ID.

[0014] When the same auxiliary device serves multiple mobile temporary facilities, the migration energy consumption of the auxiliary device is allocated according to the service characteristic value corresponding to each mobile temporary facility;

[0015] After confirming that a migration has occurred, the energy consumption that is within the migration event time window and corresponds to the migration-related status in the energy consumption to be confirmed is parsed to the migration energy consumption. After denying that a migration has occurred, the energy consumption to be confirmed is parsed to the normal operating energy consumption of the original accounting account.

[0016] The actual energy consumption in each sampling period is decomposed into normal operation energy consumption, migration energy consumption, and energy consumption to be confirmed, so that the decomposed energy consumption components are not repeatedly assigned and the sum of the energy consumption components is equal to the actual energy consumption in the corresponding sampling period. The construction carbon emissions are calculated according to the emission factors corresponding to the energy type, and the sub-item accounting results corresponding to the construction task or sub-item project are obtained.

[0017] Furthermore, the target mobile temporary facilities include temporary power supply facilities, temporary power distribution facilities, temporary rooms, mobile office facilities, temporary lighting facilities, or temporary processing facilities whose locations change with the construction progress at the construction site; the auxiliary equipment includes hoisting equipment, transport vehicles, forklifts, dismantling and assembly equipment, or rewiring equipment that participate in the relocation process of the target mobile temporary facilities; the energy consumption includes at least one of electricity consumption, fuel consumption, and gas consumption.

[0018] Furthermore, the migration status of the target mobile temporary facility is determined based on its continuous location trajectory, displacement distance, duration, and regional status, including:

[0019] The location coordinates of the target mobile temporary facility are continuously acquired according to a preset sampling period;

[0020] The adjacent displacement distance is determined based on the position coordinates of adjacent sampling points, and the cumulative displacement of the target mobile temporary facility relative to the original stable area is determined based on multiple consecutive adjacent displacement distances;

[0021] The duration of deviation is determined based on the sampling time during which the target mobile temporary facility continuously deviates from the original stable area.

[0022] The consistency of the movement direction is determined based on the directional angle between adjacent displacement vectors, and sampling points whose displacement does not meet the effective displacement condition are excluded from the calculation range of the consistency of the movement direction.

[0023] The state of the area is determined based on the relationship between the location coordinates and the boundary of the construction area.

[0024] Furthermore, determining the relocation status of the target mobile temporary facility includes:

[0025] A comprehensive migration judgment index is formed based on the cumulative displacement, duration of deviation, and consistency of movement direction.

[0026] When the target construction area has been determined according to the relocation instruction or construction task, the comprehensive relocation judgment index is further formed based on the spatial matching degree between the target mobile temporary facility and the target construction area.

[0027] When the target mobile temporary facility continuously deviates from the original stable area and the migration comprehensive judgment index reaches the preset suspected migration threshold, the migration status will be changed from stable operation status to suspected migration status.

[0028] After entering the suspected migration state, when the target mobile temporary facility re-enters the original stable area, or when the migration confirmation conditions corresponding to the cumulative displacement, continuous deviation time, and consistency of movement direction are not simultaneously met within the preset migration confirmation time limit, the migration state is restored to the stable operation state, and it is determined that no migration has occurred.

[0029] Furthermore, the migration status also includes the target area arrival status and the target area stable operation status;

[0030] When the location coordinates of the target mobile temporary facility enter the target construction area, and the location fluctuation within multiple consecutive sampling periods is within a preset stable range, the migration state is converted to the target area arrival state.

[0031] When the target mobile temporary facility maintains a preset stable state for a continuous period of time within the target construction area, and the operating state meets the preset operating conditions, the migration state is converted to the stable operating state of the target area, and the moment of conversion to the stable operating state of the target area is determined as the migration completion time.

[0032] Furthermore, determining the migration start time includes:

[0033] After the target mobile temporary facility meets the migration confirmation conditions, backtrack along the continuous position trajectory corresponding to this migration process to find the first valid sampling time when the target mobile temporary facility continuously deviates from the original stable area, and determine the first valid sampling time as the migration start time;

[0034] If, during the backtracking process, the target mobile temporary facility re-enters the original stable area, the continuous positioning data is interrupted for more than a preset time, or the migration trajectory cannot be continuously associated, the backtracking is stopped, and the first valid sampling time that is located after the stop backtracking position and belongs to the current continuous migration trajectory is determined as the migration start time.

[0035] Furthermore, based on the migration event time window and the operating status of the target mobile temporary facility, the migration energy consumption generated by the target mobile temporary facility itself is identified, including:

[0036] Historical energy consumption data of the target mobile temporary facility in a stable operating state during a preset historical period before the relocation is selected, and historical energy consumption data corresponding to shutdown, failure, communication interruption, maintenance period and energy consumption anomaly are removed;

[0037] Regarding the running status The target mobile temporary facility is determined according to the following formula. Normal energy consumption baseline within a unit sampling period:

[0038] ;

[0039] in, For the target mobile temporary facility In running state The following is the effective historical energy consumption data. The amount of valid historical energy consumption data, For indexing mobile temporary facilities, This is the time for energy consumption sampling;

[0040] For target mobile temporary facilities that continue to consume energy during relocation, the sampling time is determined according to the following formula. Energy consumption exceeding the normal energy consumption baseline within the sampling period :

[0041] ;

[0042] in, For mobile temporary facilities At sampling time Actual energy consumption For mobile temporary facilities At sampling time The running status, For mobile temporary facilities In running state Normal energy consumption baseline;

[0043] The migration energy consumption generated by the target mobile temporary facility itself is determined according to the following formula. :

[0044] ;

[0045] in, For mobile temporary facilities Its own migration energy consumption, For mobile temporary facilities The corresponding migration event time window, For mobile temporary facilities At sampling time The migration status, For the set of states related to the migration;

[0046] For target mobile temporary facilities whose energy supply is interrupted during the relocation process and whose own energy consumption is not collected, their own relocation energy consumption is not calculated, but the energy consumption generated by the corresponding relocation activities is calculated based on the auxiliary equipment involved in their hoisting, transportation, disassembly, or rewiring.

[0047] Furthermore, associating the auxiliary equipment migration energy consumption with the migration event ID includes:

[0048] The location coordinates, sampling time, energy consumption, and operating status of the auxiliary equipment are collected.

[0049] When the running time of the auxiliary equipment overlaps with the migration event time window, the location trajectory of the auxiliary equipment spatially matches the migration starting point, migration path, target construction area or corresponding work area of ​​the target mobile temporary facility, and the running status of the auxiliary equipment matches the handling, hoisting, transportation, disassembly or rewiring operations, it is determined that the auxiliary equipment participates in the migration process corresponding to the migration event ID.

[0050] Based on the start and end times of the actual handling, hoisting, transportation, disassembly, or rewiring operations performed by the auxiliary equipment, the effective relocation operation time period is determined, and the energy consumption actually collected by the auxiliary equipment during the effective relocation operation time period is determined as the relocation energy consumption of the auxiliary equipment.

[0051] Furthermore, determining the migration event corresponding to the auxiliary device includes:

[0052] When the effective migration operation time period of the auxiliary equipment overlaps with the time windows of multiple migration events, the corresponding multiple migration events are identified as candidate migration events;

[0053] Based on the overlap between the effective migration operation time period of the auxiliary equipment and the time windows of each candidate migration event, the spatial matching relationship between the location trajectory of the auxiliary equipment and the migration trajectory of the corresponding mobile temporary facility, and the operating status of the auxiliary equipment during the effective migration operation time period, the migration event corresponding to the auxiliary equipment is determined from the candidate migration events.

[0054] When multiple matching candidate migration events are determined based on the overlap relationship, the spatial matching relationship, and the operating status, the migration event corresponding to the auxiliary equipment is determined based on the task number, work instruction, or manual confirmation information.

[0055] Furthermore, when the same auxiliary equipment When serving multiple mobile temporary facilities, each mobile temporary facility should be identified separately. Corresponding service feature value ;

[0056] When the auxiliary equipment is a hoisting device, the service characteristic value is determined according to the following formula:

[0057] ;

[0058] in, For mobile temporary facilities Effective working time for performing hoisting operations For the corresponding workload;

[0059] When the auxiliary equipment is a transport vehicle, the service characteristic value is determined according to the following formula:

[0060] ;

[0061] in, For mobile temporary facilities Effective transportation time for carrying out transportation operations. This corresponds to the transportation distance;

[0062] When the auxiliary equipment is a disassembly / reassembly device or a rewiring device, the service characteristic value is determined according to the following formula:

[0063] ;

[0064] in, For mobile temporary facilities Effective working time for performing disassembly, assembly, or rewiring operations. This corresponds to the number of assignments.

[0065] The allocation weight of the auxiliary equipment migration energy consumption corresponding to each mobile temporary facility is determined according to the following formula:

[0066] ;

[0067] The energy consumption for migrating the auxiliary equipment is then allocated to the corresponding mobile temporary facilities according to the following formula:

[0068] ;

[0069] in, For the auxiliary equipment Migration energy consumption during the corresponding effective migration operation period To be allocated to mobile temporary facilities The energy consumption of auxiliary equipment migration, and meets the following requirements:

[0070] ;

[0071] This allows the energy consumption of the auxiliary equipment to be distributed among the various mobile temporary facilities in a single operation.

[0072] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0073] This invention identifies the migration status based on the continuous location trajectory, cumulative displacement, continuous deviation time, consistency of movement direction, and regional status of mobile temporary facilities. This avoids judging migration based solely on a single location coordinate or a single boundary crossing result, and can reduce misjudgments of migration caused by positioning drift, short-term position fluctuations, and abnormal sampling.

[0074] This invention establishes a migration event ID after the migration confirmation conditions are met, determines the migration start time by backtracking, and determines the migration completion time by the target mobile temporary facility reaching a stable operating state within the target construction area. It can include the relevant energy consumption during the migration confirmation delay period into the migration event time window and avoid switching the accounting account in advance before the facility has completed the migration.

[0075] This invention utilizes the same migration event to simultaneously determine the accounting account switching boundary and the migration energy consumption identification boundary, enabling the location changes of mobile temporary facilities, construction task changes, and energy consumption attribution to form a continuous data processing relationship, reducing the situation where energy consumption near the migration boundary is incorrectly attributed to the original accounting account or the target accounting account.

[0076] This invention associates the target mobile temporary facility and the auxiliary equipment involved in the migration with the migration event ID, and determines the correspondence between the auxiliary equipment and the migration event by combining the degree of time overlap, the degree of spatial trajectory matching and the degree of operational status matching. It can identify the effective migration operation time period from all the operational data of the auxiliary equipment, and avoids including idle time or operation energy consumption unrelated to the migration event in the migration energy consumption.

[0077] When the same auxiliary equipment serves multiple mobile temporary facilities, the present invention forms a service characteristic value based on the effective working time, working load, transportation distance or number of operations, and allocates the migration energy consumption of the auxiliary equipment in one go, so that the sum of the energy consumption allocated to each mobile temporary facility is equal to the actual migration energy consumption determined by the auxiliary equipment, thereby reducing the duplication of energy consumption of shared auxiliary equipment.

[0078] This invention sets up normal operating energy consumption, migration energy consumption, and energy consumption to be confirmed. After migration confirmation or migration rejection, the energy consumption to be confirmed is analyzed, so that each energy consumption component is not repeatedly assigned and the total energy consumption after decomposition is consistent with the actual collected energy consumption. This helps to avoid duplication or omission of energy consumption data during migration identification.

[0079] This invention establishes a correlation between equipment identification, location trajectory, migration status, migration event ID, construction task, accounting account, auxiliary equipment, energy consumption, emission factors, and carbon emissions, thereby forming a traceability relationship from the migration process of mobile temporary facilities to the carbon emission results of construction tasks and sub-projects, improving the completeness and traceability of the sub-item carbon emission accounting results.

[0082] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0083] Example

[0084] This embodiment provides a method for dynamic tracking and itemized accounting of carbon emissions from the construction of mobile temporary facilities, such as... Figure 1 As shown, it includes steps S101 to S108.

[0085] S101 collects data on the location, energy consumption, and operational status of mobile temporary facilities, and establishes the correspondence between construction areas, construction tasks, sub-projects, and accounting accounts.

[0086] Positioning devices, energy metering devices, and operational status acquisition interfaces are installed on the mobile temporary facilities at the construction site. The positioning devices can be GPS, BeiDou, RFID, or other positioning devices capable of continuously outputting position coordinates; the energy metering devices can be smart meters, fuel flow meters, or gas flow meters; the operational status acquisition interface is used to obtain the power-on, power-off, operation, shutdown, relocation, or fault status of the mobile temporary facilities.

[0087] For auxiliary equipment involved in the relocation of mobile temporary facilities, data such as auxiliary equipment identification, location coordinates, sampling time, energy consumption, and operating status are collected. The auxiliary equipment includes hoisting equipment, transport vehicles, forklifts, disassembly / reassembly equipment, or rewiring equipment.

[0088] Each sampled data entry includes at least the device identifier, sampling time, location coordinates, energy type, energy consumption, and operating status. Based on the device identifier, data generated by the same mobile temporary facility or auxiliary equipment at different sampling times are linked into a continuous data sequence.

[0089] This embodiment sets up construction area A and construction area B. Construction area A corresponds to the reinforcement engineering construction task TA and accounting account AC-A, while construction area B corresponds to the formwork engineering construction task TB and accounting account AC-B. Construction area A and construction area B belong to their respective sub-items of the project.

[0090] A mobile temporary power supply facility F001 is installed in construction area A. Initially, F001 supplies power to the steel reinforcement work in construction area A. As the construction progresses, it needs to be moved to construction area B to supply power to the formwork work in construction area B.

[0091] The corresponding relationship before the relocation of mobile temporary power supply facility F001 was as follows:

[0092] F001—Construction Area A—Reinforcement Engineering TA—Accounting Account AC-A.

[0093] The corresponding relationship after the relocation of mobile temporary power supply facility F001 is as follows:

[0094] F001—Construction Area B—Formwork Engineering TB—Accounting Account AC-B.

[0095] In this embodiment, the positioning sampling period for the mobile temporary power supply facility F001 is 10 seconds. In other embodiments, the sampling period can be determined based on the positioning accuracy of the positioning device, the size of the mobile temporary facility, the construction area range, and the expected migration speed.

[0096] S102, determine the migration status based on continuous position trajectory, displacement distance, duration and regional status, and include the undetermined energy consumption during the suspected migration period into the energy consumption to be confirmed.

[0097] In this embodiment, the suspected migration state refers to an intermediate state in which a mobile temporary facility has continuously deviated from its original stable area and reached the preset suspected migration judgment conditions, but the cumulative displacement, continuous deviation time, and consistency of the movement direction have not yet simultaneously met the corresponding migration confirmation conditions. Entering the suspected migration state only indicates that the mobile temporary facility may migrate, but migration has not yet been finally confirmed. Therefore, during the suspected migration state, the accounting account is not switched, and the energy consumption whose attribution is not yet determined is temporarily included in the energy consumption to be confirmed.

[0098] Set up mobile temporary facilities In the The position coordinates at each sampling time are:

[0099]

[0100] Based on the position coordinates of two adjacent sampling times, the adjacent displacement distance is calculated using the following formula. :

[0101]

[0102] Including continuous Within a sliding time window of one sampling period, the cumulative displacement is calculated according to the following formula. :

[0103]

[0104] in, The number of sampling periods contained in the sliding time window. To traverse the index during the sampling period, For adjacent displacements;

[0105] The duration of deviation is determined based on the sampling time during which the mobile temporary facility continuously deviates from its original stable area. .

[0106] For adjacent displacements For sampling points that meet the effective displacement condition, the consistency of the movement direction is calculated based on the directional angle between adjacent displacement vectors:

[0107]

[0108] in, For the first The set of indices of adjacent displacement vector pairs that satisfy the effective displacement condition within a sliding time window. The number of valid vector pairs in the set of sampling points.

[0109] When the magnitude of the displacement vector is not greater than the effective displacement threshold, the corresponding vector pair is not included in the calculation of the consistency of the movement direction, so as to avoid calculation abnormalities caused by zero displacement vector.

[0110] The cumulative displacement index is determined based on the cumulative displacement and migration, confirming the cumulative displacement threshold.

[0111]

[0112] Determine the duration metric based on the duration of deviation and the migration confirmation time threshold:

[0113]

[0114] in, To confirm the cumulative displacement threshold for migration; The threshold for migration confirmation duration.

[0115] When a target construction area has been specified in the migration instruction or construction task, the spatial matching degree is determined based on the distance between the current location and the target construction area:

[0116]

[0117] in, This represents the distance between the current location and the target construction area. To match distances in space.

[0118] When the target construction area is not determined, the spatial matching index is not calculated, and the weight corresponding to the spatial matching index is set to zero, while the sum of the weights corresponding to the other indicators is 1.

[0119] A comprehensive migration assessment index is formed based on cumulative displacement, duration, consistency of movement direction, and spatial matching degree.

[0120]

[0121] in, , , and These are the non-negative weights corresponding to cumulative displacement, duration, consistency of movement direction, and spatial matching degree, respectively, and satisfying the following:

[0122]

[0123] The weights and corresponding thresholds are preset based on the positioning error at the construction site, the normal positional fluctuation range of the mobile temporary facilities, the typical migration distance, the scale of the construction area, and the sampling period.

[0124] In this embodiment, the cumulative displacement threshold for suspected migration is 5m, the cumulative displacement threshold for confirmed migration is 20m, the duration threshold for suspected migration is 30s, and the duration threshold for confirmed migration is 60s.

[0125] During the period from 09:58:00 to 09:58:20, the location coordinates of the mobile temporary power supply facility F001 were (100.0, 50.0), (100.2, 50.1) and (100.3, 50.2), respectively. The location changes were within the normal fluctuation range, thus maintaining a stable operating state.

[0126] After 09:58:30, the mobile temporary power supply facility F001 continuously moved away from its original stable area, and its position coordinates changed sequentially as follows:

[0127] 09:58:30: (101.2, 50.6);

[0128] 09:58:40: (103.0, 51.4);

[0129] 09:58:50: (105.5, 52.8);

[0130] 09:59:00: (108.2, 54.3).

[0131] At 09:59:00, the displacement of the mobile temporary power supply facility F001 relative to its original stable position has exceeded the cumulative displacement threshold for suspected migration, and the deviation has continued for 30 seconds. Therefore, its migration status has been changed from stable operation status to suspected migration status.

[0132] Upon entering a suspected migration state, the accounting account is not directly switched based on the current location of the mobile temporary power supply facility F001. Instead, the energy consumption whose attribution is yet to be determined is temporarily included in the energy consumption pending confirmation. When the mobile temporary power supply facility F001 re-enters the original stable area, or when the migration confirmation conditions corresponding to cumulative displacement, continuous deviation time, and consistency of movement direction are not simultaneously met within the preset migration confirmation time limit, the migration state is restored to a stable operating state, and it is determined that no migration has occurred.

[0133] The mobile temporary power supply facility F001 continued to move in a basically consistent direction. At 09:59:40, its displacement relative to its original stable position exceeded 20m, the deviation time exceeded 60s, and the consistency of the moving direction reached the corresponding threshold. Therefore, the migration was confirmed, and the migration process continued to be tracked.

[0134] S103. When the migration confirmation conditions are met, a migration event ID is established, the migration start time and migration completion time are determined, and a migration event time window is formed.

[0135] After confirming the relocation of mobile temporary power supply facility F001, a migration event ID is created for this relocation process:

[0136] ME-F001-20260831-001.

[0137] The migration event ID is stored in association with at least the equipment identifier of the mobile temporary power supply facility F001, the original construction area, the target construction area, the original construction task, the target construction task, the original accounting account, and the target accounting account.

[0138] Since migration confirmation requires both cumulative displacement and duration to meet certain conditions, the confirmation of migration usually occurs later than the actual start of movement. To incorporate energy consumption during the confirmation delay into the migration event, after the migration is confirmed at 09:59:40, the trajectory is traced back along the continuous position of the mobile temporary power supply facility F001.

[0139] During the backtracking process, the first valid sampling time when the mobile temporary power supply facility F001 continuously deviated from the original stable area was found to be 09:58:30. Therefore, 09:58:30 was determined as the migration start time.

[0140] If, during the backtracking process, a temporary mobile facility re-enters the original stable area, continuous positioning data is interrupted for more than a preset time, or the migration trajectory cannot be continuously associated, the backtracking will be stopped, and the first valid sampling time that is located after the stop backtracking position and belongs to the current continuous migration trajectory will be determined as the migration start time.

[0141] At 10:00:40, the mobile temporary power supply facility F001 entered construction area B. Its subsequent location coordinates are as follows:

[0142] 10:00:40: (137.0, 70.0);

[0143] 10:00:50: (137.3, 70.2);

[0144] 10:01:00: (137.1, 70.1);

[0145] 10:01:10: (137.2, 70.2);

[0146] 10:01:20: (137.1, 70.1);

[0147] 10:01:30: (137.2, 70.2).

[0148] The maximum positional deviation of the mobile temporary power supply facility F001 within the target construction area is 0.36m, which is less than the 1m allowable positional fluctuation range set in this embodiment. With the target area stabilization time set to 50s, at 10:01:30, the mobile temporary power supply facility F001 has met the target area stabilization time and operational status conditions. Therefore, its migration state is changed to the target area stable operational state, and 10:01:30 is determined as the migration completion time.

[0149] Therefore, the time window for this migration event is:

[0150]

[0151] That is, the duration of the migration event time window is 180 seconds.

[0152] S104, control the switching of accounting accounts based on the migration completion time.

[0153] Before 10:01:30, the mobile temporary power supply facility F001 had not yet reached a stable operating state in construction area B. Therefore, the accounting account was not switched immediately based on the time it entered construction area B.

[0154] For energy consumption components generated before the migration is completed and determined to be normal operating energy consumption after processing, they will continue to be attributed to the original accounting account AC-A corresponding to the steel reinforcement project TA; for energy consumption components determined to be migration energy consumption, they will be attributed to the migration event ME-F001-20260831-001.

[0155] During the stable period in the aforementioned target area, the operation status acquisition interface continuously detected that the mobile temporary power supply facility F001 was in a powered and normal power supply state, meeting the preset operation conditions.

[0156] After confirming the relocation was completed at 10:01:30, the normal operating energy consumption of the mobile temporary power supply facility F001 was switched to the target accounting account AC-B corresponding to the template project TB.

[0157] Therefore, even if the mobile temporary power supply facility F001 has entered construction area B at 10:00:40, the period from 10:00:40 to 10:01:30 is still in the relocation completion confirmation stage, and the total energy consumption of this stage will not be directly regarded as the normal operating energy consumption of the formwork project in construction area B.

[0158] S105, Identify the facility's own migration energy consumption based on the migration event time window, and associate the auxiliary equipment migration energy consumption with the migration event ID.

[0159] This embodiment assumes that the mobile temporary power supply facility F001 remains energized or continues to supply power to the electrical load during the relocation.

[0160] Historical energy consumption data of mobile temporary power supply facility F001 during a preset historical period before the relocation was selected when it was in stable operation, and data corresponding to shutdown, fault, communication interruption, maintenance period and abnormal energy consumption were removed.

[0161] In other implementations, the normal energy consumption benchmark can be determined based on the average value of the remaining historical energy consumption data after removing abnormal historical energy consumption data.

[0162] Regarding the running status The normal energy consumption baseline within a unit sampling period is determined according to the following formula:

[0163]

[0164] in, For the target mobile temporary facility In running state The following is the effective historical energy consumption data. The amount of valid historical energy consumption data, For indexing mobile temporary facilities, This is the time for energy consumption sampling;

[0165] The historical energy consumption per unit sampling period obtained in this embodiment were 0.48 kWh, 0.51 kWh, 0.49 kWh, 0.52 kWh, 0.50 kWh, 0.51 kWh, and 0.49 kWh, respectively. Taking the median, we get:

[0166]

[0167] The 0.50kWh mentioned above represents the normal energy consumption baseline corresponding to one sampling period. The sampling period in this embodiment is 10s.

[0168] For sampling time During the sampling period, the portion of actual energy consumption exceeding the normal energy consumption benchmark is determined using the following formula:

[0169]

[0170] in, For mobile temporary facilities At sampling time Actual energy consumption For mobile temporary facilities At sampling time The running status, For mobile temporary facilities In running state Normal energy consumption baseline;

[0171] Only when the sampled data falls within the migration event time window and corresponds to a migration-related state will the corresponding excess energy consumption be included in the facility's own migration energy consumption. :

[0172] ;

[0173] in, For mobile temporary facilities Its own migration energy consumption, For mobile temporary facilities The corresponding migration event time window, For mobile temporary facilities At sampling time The migration status, For the set of states related to the migration;

[0174] For ease of explanation, 15 effective energy consumption sampling periods were selected from the migration event time window, ranging from 09:59:00 to 10:01:20, for calculation. Within these 15 sampling periods, the actual energy consumption of the mobile temporary power supply facility F001 was as follows:

[0175] 0.82kWh, 0.78kWh, 0.86kWh, 0.80kWh, 0.75kWh, 0.72kWh, 0.70kWh, 0.65kWh, 0.62kWh, 0.60kWh, 0.58kWh, 0.55kWh, 0.54kWh, 0.53kWh and 0.52kWh.

[0176] The corresponding above-baseline energy consumptions are as follows:

[0177] 0.32kWh, 0.28kWh, 0.36kWh, 0.30kWh, 0.25kWh, 0.22kWh, 0.20kWh, 0.15kWh, 0.12kWh, 0.10kWh, 0.08kWh, 0.05kWh, 0.04kWh, 0.03kWh and 0.02kWh.

[0178] Adding the above above-baseline energy consumption, we get:

[0179]

[0180] Therefore, within the aforementioned effective energy consumption sampling period, the migration energy consumption generated by the mobile temporary power supply facility F001 itself is 2.52 kWh. For mobile temporary facilities that stop energy supply during migration and whose own energy consumption is not collected, their own migration energy consumption is not calculated; instead, the energy consumption of the corresponding migration activity is calculated through the auxiliary equipment involved in the migration.

[0181] This embodiment also employs a transport vehicle V001 to participate in the relocation of the mobile temporary power supply facility F001. The location trajectory, operation time, running status, and diesel consumption of the transport vehicle V001 are collected.

[0182] When the running time of transport vehicle V001 overlaps with the time window of the migration event, the location trajectory of transport vehicle V001 spatially matches the migration starting point, migration path, or target construction area of ​​mobile temporary power supply facility F001, and the running status of transport vehicle V001 matches the transportation operation, it is determined that transport vehicle V001 participates in this migration event.

[0183] In this embodiment, the effective relocation operation time of transport vehicle V001 is from 09:58:50 to 10:01:10, during which 3.0L of diesel fuel is actually consumed. Therefore, 3.0L is taken as the energy consumption for the relocation of auxiliary equipment corresponding to transport vehicle V001, and the normal operating energy consumption benchmark of the transport vehicle is no longer deducted from this 3.0L.

[0184] Since the construction management data contains a transportation task number corresponding to migration event ME-F001-20260831-001, the following association is directly established:

[0185] V001—ME-F001-20260831-001—F001.

[0186] When the effective relocation operation time period of transport vehicle V001 overlaps with the time windows of multiple relocation events, the corresponding relocation events are identified as candidate relocation events. The process involves determining whether the effective relocation operation time period of V001 overlaps with the time windows of each candidate relocation event, whether the transport trajectory of V001 matches the relocation trajectory of the corresponding mobile temporary facility, and whether V001 is in a loading, transporting, or unloading state during the overlapping time period. Based on these factors, the relocation event corresponding to V001 is determined. If multiple matching candidate relocation events still exist, the actual relocation event served by V001 is further determined based on the transport task number, work instruction, or manual confirmation information.

[0187] S106 When the same auxiliary equipment serves multiple mobile temporary facilities, the migration energy consumption of the auxiliary equipment is allocated according to the service characteristic value of each mobile temporary facility.

[0188] This embodiment further assumes that transport vehicle V001 also serves another mobile temporary facility F002 during the corresponding operation. The effective transport time of transport vehicle V001 to mobile temporary power supply facility F001 is 20 minutes, and the transport distance is 4 km; the effective transport time to mobile temporary facility F002 is 10 minutes, and the transport distance is 2 km.

[0189] For transport vehicles, service characteristic values ​​are determined based on effective transport time and transport distance:

[0190]

[0191] in, For auxiliary equipment For mobile temporary facilities Effective transportation time for carrying out transportation operations. This represents the corresponding transportation distance.

[0192] The service characteristic value corresponding to mobile temporary power supply facility F001 is:

[0193]

[0194] The service characteristic value corresponding to mobile temporary facility F002 is:

[0195]

[0196] The allocation weight for each mobile temporary facility is determined according to the following formula:

[0197]

[0198] Therefore, the allocation weights corresponding to mobile temporary power supply facility F001 and mobile temporary power supply facility F002 are as follows:

[0199]

[0200]

[0201] The migration energy consumption of transport vehicle V001 shall be allocated according to the following formula:

[0202]

[0203] Therefore, the diesel consumption allocated to the mobile temporary power supply facility F001 is:

[0204]

[0205] The diesel consumption allocated to mobile temporary facility F002 is as follows:

[0206]

[0207] The allocation result satisfies:

[0208]

[0209] That is, the sum of the auxiliary equipment relocation energy consumption allocated to each mobile temporary facility is equal to the actual relocation energy consumption of transport vehicle V001 during the effective relocation operation period.

[0210] For hoisting equipment, the service characteristic value can be determined by multiplying the effective hoisting operation time by the operating load; for disassembly or rewiring equipment, the service characteristic value can be determined by multiplying the effective operation time by the number of operations.

[0211] S107, Analyze the energy consumption to be confirmed based on the migration confirmation results, and decompose the actual energy consumption into normal operation energy consumption, migration energy consumption and energy consumption to be confirmed.

[0212] For the unconfirmed energy consumption generated by the mobile temporary power supply facility F001 during the suspected relocation period, after the relocation is confirmed, it is analyzed based on the relocation start time determined by retrospection, the operating status of the corresponding sampling period, and the normal energy consumption benchmark.

[0213] For energy consumption exceeding the baseline that falls within the migration event time window and corresponds to a migration-related state, it is resolved as migration energy consumption; for energy consumption components determined to be normal operation, they are resolved to the original accounting account AC-A. If a subsequent negative migration occurs, the unconfirmed energy consumption during the suspected migration period is resolved as the normal operation energy consumption of the original accounting account AC-A.

[0214] Within the aforementioned 15 effective energy consumption sampling periods, the actual total energy consumption collected was 10.02 kWh. The normal operating energy consumption, determined according to the normal energy consumption benchmark, is:

[0215]

[0216] The identified migration energy consumption is 2.52 kWh. After completing the analysis of the energy consumption to be confirmed, the energy consumption to be confirmed within the corresponding sampling period is 0, thus satisfying:

[0217] 10.02 = 7.50 + 2.52 + 0

[0218] Right now:

[0219]

[0220] in, This represents the actual energy consumption for this sampling period. To determine the energy consumption attributable to normal operation, To determine the additional energy consumption attributable to migration events, This refers to energy consumption for which attribution cannot be determined at this time.

[0221] By decomposing the actual collected energy consumption according to the energy consumption amount, the energy consumption components in normal operation energy consumption, migration energy consumption and unconfirmed energy consumption are not repeatedly assigned, and the total energy consumption after decomposition is consistent with the actual collected energy consumption amount.

[0222] S108, calculate the construction carbon emissions based on the emission factors corresponding to the energy type, and obtain the sub-item accounting results.

[0223] Calculate the carbon emissions corresponding to each type of energy consumption after attribution using the following formula:

[0224]

[0225] in, To meet the energy consumption requirements after ownership, For the emission factors corresponding to the energy type, This represents the corresponding carbon emissions.

[0226] The power emission factor used in this embodiment is 0.570. The diesel emission factor is 2.63. The emission factors mentioned are only used to illustrate the calculation process; in actual applications, emission factors corresponding to the calculation time and calculation area should be used.

[0227] The carbon emissions corresponding to the relocation energy consumption of the mobile temporary power supply facility F001 are:

[0228]

[0229] The diesel consumption of transport vehicle V001 allocated to mobile temporary power supply facility F001 is 2.4L, and the corresponding carbon emissions are:

[0230]

[0231] Therefore, the carbon emissions from the relocation activity attributable to mobile temporary power supply facility F001 in this relocation event are:

[0232]

[0233] That is approximately 7.75 .

[0234] Energy consumption of auxiliary equipment within the migration event time window but outside the effective migration operation time period is not included in the corresponding migration event, but is attributed according to the construction task actually served by the auxiliary equipment, the operating status, and the original accounting rules.

[0235] Finally, the equipment identifier, sampling time, location coordinates, migration status, migration event ID, original construction area, target construction area, original construction task, target construction task, original accounting account, target accounting account, auxiliary equipment identifier, energy type, energy consumption type, energy consumption, emission factor, and carbon emission are associated and stored.

[0236] Through the above processing, changes in the location, construction tasks, and energy consumption of mobile temporary power supply facility F001 are all associated through the migration event ME-F001-20260831-001. Before the migration is completed, the accounting account is not switched prematurely due to mobile temporary power supply facility F001 entering construction area B. When auxiliary equipment serves multiple mobile temporary facilities, the migration energy consumption of the auxiliary equipment is allocated in one go according to the service characteristic value. Through the decomposition and analysis of normal operation energy consumption, migration energy consumption, and energy consumption to be confirmed, the total energy consumption after decomposition is kept consistent with the actual collected energy consumption, thereby obtaining the construction carbon emission sub-item accounting results that match the steel reinforcement engineering, formwork engineering, and corresponding sub-item engineering projects.

[0237] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
