A boiler auxiliary machinery installation and dismounting construction process simulation management system

Abstract

This invention belongs to the field of construction process simulation management technology, and relates to a simulation management system for the installation and dismantling of boiler auxiliary machinery. This invention acquires residual occupied objects in completed processes (such as the preheater and fan processes) that still occupy construction space areas, determines candidate temporary storage areas, and forms a priority release sequence accordingly. When the priority release sequences of multiple construction space areas sequentially connect and return to the starting construction space area, and none of the residual occupied objects in the chain have candidate temporary storage areas that can be used without first releasing other construction space areas within the chain, a closed release chain is formed. A backup temporary storage area is determined from outside the closed release chain, generating a chain-breaking and clearing sequence. This invention can identify construction space loops caused by the continuous transfer of residual occupied objects and break the closed release chain through transfers outside the chain, reducing repeated transfers of residual occupied objects and construction waiting times.

Description

Technical Field

[0001] This invention relates to the field of construction process simulation management technology, and in particular to a simulation management system for the installation and dismantling of boiler auxiliary machinery. Background Technology

[0002] During boiler unit overhaul and construction, to improve the efficiency of the installation and dismantling of boiler auxiliary machinery such as preheaters and fans, a simulation management approach combining construction schedule planning and 3D construction models is currently commonly used. This approach arranges construction according to the planned time, transportation route, hoisting area, and temporary storage area for each construction process, and handles conflicts in construction space by adjusting the construction sequence or temporary storage location. Currently, after a construction process is completed, the corresponding construction space is typically repurposed for subsequent processes.

[0003] However, during the parallel installation and dismantling of the preheater and fan, preheater modules, fan components, dismantling tools, transport vehicles, and temporary supports corresponding to completed processes may still continue to occupy construction space. For example, this may be necessary to free up space for the fan rotor hoisting. The area needs to be The preheater module in the middle is transferred to the area ;area The area is currently occupied by another residual object and needs to be released first. ;area Another waiting area The corresponding fan process can only be completed before it can be released, thus forming a region. ,area ,area A sequential, mutually waiting space release loop occurs. At this point, although each residual occupied object individually has a candidate temporary storage area, continuous analysis reveals no space release action that can be executed first.

[0004] The aforementioned space release cycle easily leads to repeated adjustments of preheater modules and fan components between multiple construction space areas. This causes the current construction conflict to be resolved only to be transferred to subsequent processes, resulting in continuous waiting for cranes, transport vehicles, and construction personnel. In severe cases, it can prevent both the preheater and fan processes from continuing. Therefore, existing construction simulation management methods still struggle to accurately identify space release cycles formed by the continuous transfer of residual occupied objects, and are unable to prevent new space release cycles from occurring after the current cycle is resolved. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the above-mentioned background technology that during the parallel installation and dismantling of preheaters and fans, the residual objects corresponding to the completed procedures continue to occupy the construction space area, causing multiple construction space areas to form a space release cycle of mutual waiting, and resulting in repeated transfer of residual objects and continuous waiting of construction procedures. Therefore, a simulation management system for the installation and dismantling construction process of boiler auxiliary machinery is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a simulation management system for the installation and dismantling of boiler auxiliary machinery, comprising: The area determination module is used to obtain the residual occupied objects in the preheater process and the fan process that are still occupying the construction space area corresponding to the completed process, and to determine the candidate temporary storage area for each residual occupied object. The sequence formation module is used to determine the construction space areas that need to be released before the residual occupied objects are transferred, based on the candidate temporary storage areas, and to form a priority release order; The closed release module is used to select a construction space area as the starting construction space area, track the construction space areas along the priority release order, and form a closed release chain when the tracking returns to the starting construction space area and there are no candidate temporary storage areas that can be used without first releasing other construction space areas that have been tracked, since none of the residual occupied objects tracked have been released. The chain breakage and clearance module is used to determine the backup temporary storage area from outside the closed release chain, transfer the residual occupied objects in the closed release chain that can be transferred to the backup temporary storage area to the backup temporary storage area, and generate the chain breakage and clearance sequence. The sequence update module is used to redetermine the priority release sequence based on the chain break clearance sequence. When no new closed release chain is formed, it adjusts the transfer arrangement of residual occupied objects and updates the construction sequence of the preheater process and the fan process.

[0007] In summary, due to the adoption of the above-mentioned simulation management system for the installation and dismantling of boiler auxiliary machinery, the beneficial effects of this invention are: This invention identifies residual occupied objects in the construction space areas corresponding to completed preheater and fan processes, and determines the construction space areas that need to be released first based on candidate temporary storage areas, thus forming a priority release order. This method does not directly treat the construction space area as usable space after the process is completed. Instead, it continues to consider the actual occupancy of preheater modules, fan components, dismantling tools, transport vehicles, and temporary supports. A priority release order is formed when there are no candidate temporary storage areas that can be used without first releasing other construction space areas, thereby ensuring that the construction space release judgment corresponds to the actual transfer conditions of the residual occupied objects.

[0008] This invention continuously tracks construction space areas along a priority release sequence. After returning to the initial construction space area, it further determines whether there are candidate temporary storage areas for residual occupied objects within the chain that can be used without first releasing other construction space areas within the chain. This method can distinguish between continuous occupation of construction space with potential for direct transfer and release cycles of space that truly lack a first-mover advantage. A closed release chain is formed when the cycle connection is satisfied and there is no direct transfer exit, thereby reducing misjudgments of construction space cycle waiting.

[0009] This invention identifies a backup temporary storage area outside the closed release chain, and first transfers the corresponding residual occupied objects to this area, thus releasing their original occupied construction space. Following the chain-breaking and clearance sequence, other residual occupied objects are transferred sequentially. Subsequently, based on the actual released construction space areas, the priority release order and the construction sequence for updating the preheater and fan processes are re-determined. This method utilizes the construction space outside the chain to form the starting point for the closed release chain, and allows the subsequent transfer arrangements of residual occupied objects to be adjusted as construction space areas are continuously released, reducing the likelihood of a new cycle of waiting after the current space release cycle is completed.

[0011] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a simulation management system for the installation and dismantling of boiler auxiliary machinery. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0012] The specific implementation process of the present invention will be described below with reference to the embodiments.

[0013] Example 1: See Figure 1 - Figure 4 A simulation management system for the installation and dismantling of boiler auxiliary machinery includes a region determination module, a sequence formation module, a closure release module, a chain break clearing module, and a sequence update module.

[0014] In this embodiment, the boiler auxiliary machinery installation and dismantling construction process simulation management system obtains the construction schedule, three-dimensional construction model and the on-site location of each object, generates the transfer arrangement of residual occupied objects and the construction sequence of preheater process and fan process in the three-dimensional construction model; after the corresponding transfer is completed on site, the occupancy status of the construction space area is updated according to the actual location.

[0015] This invention addresses the problem that during the parallel installation and dismantling of preheaters and fans, preheater modules, fan components, dismantling tools, transport vehicles, and temporary supports corresponding to completed processes continue to occupy construction space, requiring the continuous transfer of residual occupied objects between multiple construction space areas. The invention proposes a simulation management method based on the step-by-step release of construction space and the identification of closed release chains.

[0016] First, the region determination module identifies residual occupied objects in the preheater and fan processes that have been completed but still occupy construction space areas. Based on the occupied range and transfer path of these residual occupied objects, candidate temporary storage areas are determined. Then, the sequence formation module identifies the construction space areas that need to be released before the residual occupied objects can be used without first releasing other construction space areas, forming a priority release sequence. Further, the closed release module tracks construction space areas step-by-step along the priority release sequence. When multiple construction space areas connect sequentially and return to the starting construction space area, and none of the residual occupied objects in the chain have candidate temporary storage areas that can be used without first releasing other construction space areas within the chain, a closed release chain is formed. Based on this, the chain-breaking and clearing module determines backup temporary storage areas outside the closed release chain. Residual occupied objects that can be transferred to the backup temporary storage area are transferred first, releasing their original occupied construction space areas. This construction space area then drives the sequential transfer of the remaining residual occupied objects in the chain, forming a chain-breaking and clearing sequence. Finally, the sequence update module re-determines the priority release order based on the actual construction space areas released during the chain break clearance process, and adjusts the transfer arrangement of residual occupied objects when no new closed release chain is formed, while updating the construction sequence of the preheater process and the fan process.

[0017] S1, the area determination module is used to obtain the residual occupied objects in the preheater process and the fan process that are still occupying the construction space area corresponding to the completed process, and to determine the candidate temporary storage area for each residual occupied object.

[0018] Considering the preheater and fan installation and dismantling process, the completion of a construction step does not necessarily mean the construction space is simultaneously released. For example, after the preheater module is dismantled, it may remain in the original construction space; after the fan components are transported, they may remain in a temporary storage location; and dismantling tools, transport vehicles, and temporary supports may continue to occupy the construction space after the corresponding steps are completed. If the construction space is directly designated as usable area based solely on the completion time of each step, subsequent preheater and fan installations may conflict with the actual remaining occupied areas.

[0019] Therefore, this step does not directly determine whether the construction space area should be released based on whether the process is completed. Instead, it obtains the actual occupancy status of the objects corresponding to the completed processes and filters out candidate temporary storage areas that can be reached and accommodated, providing a basis for subsequent determination of whether other construction space areas need to be released first.

[0020] In one specific embodiment, the determination of residual occupied objects and candidate temporary storage areas includes the following steps: S101. Determine the completed preheater and fan processes from the construction schedule, and obtain the preheater modules, fan components, dismantling tools, transport vehicles, and temporary supports corresponding to the completed processes; match the positions of the objects in the three-dimensional construction model with the on-site positions after the corresponding processes are completed, and determine the objects still located within the construction space area as residual occupied objects.

[0021] Specifically, the on-site location of each object can be obtained from the on-site positioning device, construction records, or on-site scanning results, and mapped to the three-dimensional construction model to determine whether the corresponding object still occupies the construction space area after the process is completed.

[0022] S102. For each remaining occupied object, determine the currently occupied construction space area and its scope based on its outer contour in the three-dimensional construction model; then select a construction space area from other construction space areas that can accommodate the occupied scope.

[0023] Specifically, the occupied area of ​​the residual object is compared with the area of ​​each construction space. When the occupied area of ​​the residual object can be completely located within the corresponding construction space area, it is determined that the construction space area can accommodate the residual object.

[0024] S103. Take the construction space area currently occupied by the residual object as the starting point of the transfer and the selected construction space area as the ending point of the transfer. Determine the transfer path based on the connectivity of adjacent construction space areas in the three-dimensional construction model. When there is a transfer path that can continuously reach the ending point, retain the corresponding ending point as a candidate temporary storage area.

[0025] Specifically, the construction space areas that the residual occupied objects pass through sequentially from the transfer start point to the transfer end point are checked. When adjacent construction space areas can be continuously connected and the construction space areas through which the transfer path passes can accommodate the occupied area of ​​the residual occupied objects, it is determined that the transfer path can continuously reach the transfer end point.

[0026] S2, the sequence formation module is used to determine the construction space areas that need to be released before the residual occupied objects are transferred, based on the candidate temporary storage areas, and to form a priority release order.

[0027] Considering that although candidate temporary storage areas may meet the requirements in terms of occupancy range and transfer path, they may already be occupied by other residual objects. If the system immediately changes the target location as soon as it detects that a candidate temporary storage area is occupied, it is easy to continuously search for new temporary storage locations among multiple construction space areas, without being able to determine whether the current residual object truly needs to wait for other construction space areas to be released first.

[0028] Therefore, this step first determines whether there are candidate temporary storage areas for the remaining occupied objects that can be used without first releasing other construction space areas; only when there are no such candidate temporary storage areas will the construction space areas that need to be released first for the current transfer be further determined, thus forming a priority release order with actual sequential constraints.

[0029] In one specific embodiment, the formation of the priority release order includes the following steps: S201. For each residual occupied object, read its candidate temporary storage area in sequence, and determine the construction space area passed through by each transfer path according to the transfer path from the construction space area currently occupied by the residual occupied object to each candidate temporary storage area.

[0030] S202. Compare the construction space areas and corresponding candidate temporary storage areas traversed by each transfer path with the construction space areas occupied by other residual occupants. When neither the construction space areas traversed by the transfer path nor the corresponding candidate temporary storage areas are occupied by other residual occupants, the corresponding candidate temporary storage area is determined as a candidate temporary storage area that can be used without first releasing other construction space areas.

[0031] In a preferred embodiment, to further eliminate time occupancy conflicts, the estimated times for residual occupants to enter and leave the candidate temporary storage area, as well as the estimated times for subsequent preheater and fan processes to begin and end use of the construction space area, are obtained. The estimated entry and exit times are determined based on the transfer schedule of the residual occupants, while the estimated start and end times for subsequent preheater and fan processes are obtained from the construction schedule. The time overlap length is calculated using the following formula: The estimated entry time is the time when the residual occupied object arrives at the candidate temporary storage area in the transfer arrangement, and the estimated departure time is the time when the residual occupied object leaves the candidate temporary storage area in the transfer arrangement.

[0032]

[0033] In the formula, Indicates the first The estimated dwell time of the residual occupant in the candidate temporary storage area is related to the first The overlap length between the time that subsequent preheater or fan processes use the construction space area; The sequence number of the residual occupied object, taken as a positive integer; Indicates the sequence number of the subsequent preheater process or fan process, and takes a positive integer; Indicates the first The estimated time for a residual object to enter the candidate temporary storage area, where the first index... Corresponding residual occupied object sequence number, second subscript Corresponding entry time; Indicates the first The estimated time for a residual object to leave the candidate temporary storage area, where the second index... Corresponding departure time; Indicates the first The estimated start date for the use of the construction space area for subsequent preheater or fan processes, where the first subscript... Corresponding to the subsequent process sequence number, the second subscript Corresponding start time; Indicates the first The estimated time for the completion of subsequent preheater or fan processes using the construction space area, where the second subscript... Corresponding end time; This indicates that the larger value is selected from the time values ​​compared within the parentheses; This indicates that the smaller value is taken from the time values ​​compared within the parentheses; constants in the formula This indicates the lower limit of the time overlap length. All the above time parameters use the same time unit; when... equal When, it is determined that there is no time overlap between the two; when Greater than When that happens, exclude the corresponding candidate temporary storage area.

[0034] In this embodiment, the lower limit of the time overlap length is set to 0 because this value is used to determine whether the time when the residual object occupies the candidate temporary storage area overlaps with the time when the subsequent preheater process and fan process use the construction space area. When the time overlap length is 0, there is no overlap between the two time periods. When the time overlap length is greater than 0, there is a situation where the construction space area is occupied at the same time. Therefore, there is no need to set other judgment values.

[0035] S203. When there are no candidate temporary storage areas available for use without prior release of other construction space areas for the remaining occupied object, a priority release order is established for candidate temporary storage areas occupied by other remaining occupied objects that can receive the current remaining occupied object after release. Once any candidate temporary storage area is released and available for use, other priority release orders corresponding to the current remaining occupied object are no longer tracked. When establishing the priority release order, construction space areas that need to be released first are arranged before the construction space areas currently occupied by the corresponding remaining occupied object.

[0036] Specifically, preheater module A currently occupies construction space area A, and construction space area B is its candidate temporary storage area, but construction space area B is currently occupied by fan component B. When there are no other candidate temporary storage areas for preheater module A that can be used without first releasing a construction space area, it is determined that construction space area B needs to be released first, forming a priority release order where construction space area B is released before construction space area A. This order is adopted because only after construction space area B is released can preheater module A be transferred from construction space area A to construction space area B.

[0037] S3, the closed release module is used to form a closed release chain based on the priority release order.

[0038] Considering the continuous transfer of multiple residual occupied objects, even if each residual occupied object individually has a candidate temporary storage area, there may be situations where the previous construction space area waits for the next construction space area to be released, and the next construction space area eventually waits again for the initial construction space area to be released. If only a single transfer is analyzed, it is impossible to identify construction space cycles where there is no overall space release action that can be executed first.

[0039] Therefore, this step tracks the construction space areas level by level in the priority release order, and after tracking back to the starting construction space area, it continues to determine whether there are still candidate temporary storage areas in the chain that can be used without first releasing other construction space areas that have been tracked, thus eliminating the situation where a loop is formed on the surface but there are still executable transfer paths.

[0040] In one specific embodiment, the formation of the closed release chain includes the following steps: S301. Select a residual occupied object from the residual occupied objects with priority release order, determine the construction space area currently occupied by it as the starting construction space area, and determine the construction space area that needs to be released first according to the corresponding priority release order.

[0041] S302. Take the construction space area that needs to be released first as the construction space area being tracked, continue to read the priority release order of the remaining occupied objects in the construction space area, and track them sequentially. If a candidate temporary storage area appears during the tracking process that can be used without releasing other construction space areas that have been tracked first, then terminate the current tracking.

[0042] S303. When the tracking returns to the starting construction space area, check each residual occupied object that the tracking has passed through one by one; when there are no candidate temporary storage areas for each residual occupied object that can be used without first releasing other construction space areas that the tracking has passed through, form a closed release chain for the construction space areas that the tracking has passed through.

[0043] When the same residual occupied object corresponds to multiple priority release sequences, they are tracked separately; if any priority release sequence can terminate the tracking, a closed release chain corresponding to the current residual occupied object is not formed based on other priority release sequences. S301 to S303 are executed sequentially for construction space areas with priority release sequences to avoid missing other closed release chains.

[0044] See Figure 3 In this embodiment, construction space area A, construction space area B, and construction space area C form a spatial dependency relationship of a closed release chain. Specifically, preheater module A is located in construction space area A, and its transfer requires construction space area B to be released first; fan component B in construction space area B requires construction space area C to be released first; and preheater module C in construction space area C requires construction space area A to be released first.

[0045] In this embodiment, the construction space area A currently occupied by preheater module A is first selected as the starting construction space area because construction space area A has already formed a priority release order and can serve as the starting point for tracking the priority release order. Subsequently, construction space area B is determined according to the priority release order corresponding to preheater module A. The reason for determining construction space area B is that preheater module A currently does not have any candidate temporary storage areas that can be used without first releasing other construction space areas, while construction space area B can receive preheater module A after its release is completed.

[0046] Then, taking construction space area B as the currently tracked construction space area, the same judgment is performed on the fan component B in it, and it is determined that construction space area C needs to be released first; further, the same judgment is performed on the preheater module C in construction space area C, and it is determined that construction space area A needs to be released first. At this time, the tracking returns to construction space area A.

[0047] After tracing back to the initial construction space area, instead of directly forming a closed release chain for construction space areas A, B, and C, the system continues to check whether there are candidate temporary storage areas for preheater module A, fan component B, and preheater module C that can be used without first releasing the aforementioned construction space areas. Only when none of the three have such candidate temporary storage areas will construction space areas A, B, and C be formed into a closed release chain.

[0048] The above determination method is adopted because if we only return to the starting construction space area based on the priority release order, there may still be a situation where one of the remaining occupied objects can be directly transferred to other candidate temporary storage areas; by continuing to check the candidate temporary storage areas of each remaining occupied object, we can avoid mistakenly forming a closed release chain of construction space areas that can still be transferred.

[0049] S4, the chain break and clear module is used to determine a backup temporary storage area outside the closed release chain that can receive residual occupied objects in the chain, transfer the corresponding residual occupied objects to the backup temporary storage area, and generate the chain break and clear sequence.

[0050] Considering that construction space areas within a closed release chain are mutually waiting, continuing to rearrange residual occupied objects within the closed release chain will only change the position of the residual occupied objects within the chain, and will not create a construction space area that can be actually released first. Furthermore, simply requiring the target construction space area to be outside the closed release chain is insufficient to guarantee that the transfer can be executed. When the transfer path of the residual occupied object to that area still passes through other construction space areas within the closed release chain, the transfer action is still restricted by the closed release chain.

[0051] Therefore, this step simultaneously determines the backup temporary storage area and its corresponding transfer path, identifies the backup temporary storage area that can be used without first releasing other construction space areas within the chain from outside the closed release chain, and first releases one construction space area within the chain using the transfer outside the chain, and then uses the released construction space area to drive the transfer of other residual occupied objects step by step.

[0052] In one specific embodiment, determining the backup temporary storage area and the order of clearing out broken chains includes the following steps: S401. From the candidate temporary storage areas outside the closed release chain, select candidate temporary storage areas that can accommodate the occupied area of ​​each chain's residual occupied object, and determine the transfer path of the corresponding residual occupied object from the currently occupied construction space area to the candidate temporary storage area.

[0053] S402. Exclude candidate temporary storage areas whose transfer paths pass through other construction space areas within the closed release chain; for the remaining candidate temporary storage areas, determine whether they can be used without first releasing the construction space areas within the closed release chain, and determine the candidate temporary storage areas that meet this condition as backup temporary storage areas.

[0054] S403. Select one residual occupied object from the chain that can be transferred to the backup temporary storage area as the first residual occupied object to be transferred, transfer it to the backup temporary storage area, and determine the construction space area originally occupied by it as the first released construction space area in the closed release chain.

[0055] S404. According to the priority release order in the closed release chain, determine the residual occupied objects in the chain that can be used as candidate temporary storage areas in the previous released construction space area, and arrange the transfer order of each residual occupied object in the chain according to the determined order to form the chain break clearance order.

[0056] See Figure 4 In this embodiment, before the chain breaks, construction space areas A, B, and C form a closed release chain. Construction space area D is located outside the closed release chain and is used as a backup temporary storage area. Specifically, construction space areas A, B, and C have already formed a closed release chain. Construction space area D is determined outside the closed release chain, and it is judged whether construction space area D can serve as a backup temporary storage area for residual occupied objects in the closed release chain.

[0057] First, the occupancy range of each residual object is compared with the construction space area D. In this embodiment, preheater module A is selected because construction space area D can accommodate the occupancy range of preheater module A. Then, the transfer path of preheater module A from construction space area A to construction space area D is determined. This transfer path does not pass through construction space areas B and C. Therefore, preheater module A can be transferred to construction space area D without first releasing other construction space areas within the closed release chain. Based on this, construction space area D is designated as the backup temporary storage area for preheater module A. The reason for selecting construction space area D, rather than other construction space areas in the closed release chain, is that the construction space areas in the closed release chain are all waiting for each other. Continuing to adjust residual objects between construction space areas A, B, and C will not first generate a released construction space area. Construction space area D is located outside the closed release chain, and its transfer path does not pass through other construction space areas within the closed release chain, therefore, the transfer can be performed first.

[0058] Then, preheater module A is transferred from construction space area A to construction space area D, thus releasing construction space area A. After construction space area A is released, the next residual occupying object is not pre-designated, but is judged according to the priority release order in the closed release chain; since preheater module C can use the previously released construction space area A as a candidate temporary storage area, preheater module C is transferred from construction space area C to construction space area A, thus releasing construction space area C.

[0059] Subsequently, the remaining occupied objects are determined according to the priority release order in the closed release chain. Fan component B can be transferred using the already released construction space area C. Therefore, fan component B is transferred from construction space area B to construction space area C, so that construction space area B is released. This forms the broken chain clearance sequence of preheater module A, preheater module C, and fan component B being transferred in sequence.

[0060] The above selection process ensures that the determination of the backup temporary storage area is not an arbitrary choice of construction space area outside the closed release chain, but simultaneously satisfies the requirements of being able to accommodate the remaining occupied objects and that the transfer path is not restricted by other construction space areas within the closed release chain. After releasing one construction space area first, the subsequent transfers are completed in sequence using the already released construction space areas, thereby reducing the need to repeatedly change the temporary storage location of the remaining occupied objects in order to release the closed release chain.

[0061] If there is no suitable backup temporary storage area outside the closed release chain, the current chain clearance will be suspended. Once the construction space outside the closed release chain is released, the remaining occupied objects are transferred, or the occupancy status of the construction space area through which the transfer path passes changes, a new backup temporary storage area will be determined.

[0062] S5, the sequence update module is used to redetermine the priority release sequence based on the chain break clearance sequence. When no new closed release chain is formed, the transfer arrangement of residual occupied objects is adjusted according to the chain break clearance sequence, and the construction sequence of the preheater process and the fan process is updated.

[0063] Considering that the locations of remaining occupied objects and the occupancy of construction space have changed after the chain-breaking and clearance operation, the priority release order established before the chain-breaking may no longer be valid. If the original priority release order is still used, it may cause remaining occupied objects that can be directly transferred to continue waiting, or cause a new closed release chain to be formed in subsequent construction phases even though the current closed release chain has been broken.

[0064] Therefore, this step utilizes the continuously released construction space areas generated during the chain-breaking and clearing process to reassess the transfer conditions of the remaining occupied objects that have not yet been transferred, simultaneously cancels the advance release requirements that are no longer needed, and updates the transfer arrangements of the remaining occupied objects and the construction sequence of the preheater process and the fan process when the newly formed priority release sequence does not generate a new closed release chain.

[0065] In one specific embodiment, the priority release order redetering and construction sequence update include the following steps: S501. Process the residual occupied objects in the chain in the order of chain breakage and clearance, and generate the transfer arrangement of the corresponding residual occupied objects in the three-dimensional construction model. After the transfer of a residual occupied object in the chain is completed on site according to the transfer arrangement, update its actual position, and re-judge the construction space area originally occupied by it as a candidate temporary storage area for the residual occupied objects that have not yet been transferred.

[0066] S502. For residual occupied objects within the chain that have not yet been transferred, determine whether they can be transferred using the already released construction space area; if the transfer can be completed, cancel the original priority release requirement of the residual occupied object; if the transfer cannot be completed, retain the priority release requirement of the corresponding construction space area, and rearrange the priority release order according to the retained priority release requirements.

[0067] S503. Track the rearranged priority release order according to method S3; if a new closed release chain is formed, the current remaining transfer arrangement is not executed, and the determination of the backup temporary storage area is re-executed; if a new closed release chain is not formed, the transfer order of the remaining residual occupied objects in the chain break clearance sequence is adjusted according to the newly determined priority release order. After each residual occupied object is transferred, the transfer order of the remaining residual occupied objects is adjusted according to the released construction space area until the residual occupied objects in the chain break clearance sequence are transferred.

[0068] S504. Determine the construction space areas required for each preheater process and fan process, and determine the release order of the corresponding construction space areas according to the chain breakage and clearance sequence; for each preheater process and fan process, determine the last construction space area to be released in all required construction space areas, and on the basis of satisfying the construction sequence of preheater process and fan process already determined in the construction schedule, arrange the preheater process and fan process that meet the execution conditions according to the release order of the last released construction space area to form an updated construction sequence.

[0069] In a preferred embodiment, to ensure that the preheater process and the fan process only commence construction after all required construction space areas have been released, the time when the corresponding process has the necessary construction space conditions is determined according to the release time of each construction space area:

[0070] In the formula, Indicates the first The time required for each preheater process or fan process to have all the necessary construction space conditions; The serial number represents the preheater process or the fan process, and is a positive integer. Indicates the first The release time required for the first construction space area of ​​each process, where the first subscript Corresponding process number, second subscript Corresponding to the first construction space area; Indicates the first The release time required for the second construction space area in each process, where the second subscript This corresponds to the second construction space area; Indicates the first The first process requires the first Release time for each construction space area, including the second subscript Corresponding to the One construction space area; Indicates the first The total number of construction space areas required for each process, rounded to a positive integer; The release times from the second construction space area are listed sequentially up to the [number missing]. Release time for each construction space area; This indicates that the maximum release time is taken from all the release times within the parentheses. All release times use the same time unit, therefore... For the first The latest release time for all construction space areas required for each process; while satisfying the original construction sequence, according to... The preheater process and the fan process are arranged from morning to night as they are ready for execution.

[0071] In this embodiment, the maximum value among the release times of each construction space area is taken as the time when the corresponding preheater process or fan process has all the construction space conditions. This is because if any construction space area required by the same process has not been released, the process does not have all the construction space conditions. Therefore, the construction space area that is finally released determines the earliest time when the process can enter the construction schedule.

[0072] This ensures that the resumption of the preheater and fan processes is consistent with the actual release of construction space after the removal of residual occupied objects, avoiding a cycle of waiting for construction space to resume after the closed release chain is broken due to some construction space not yet being released.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the simulation management system for the installation and dismantling of boiler auxiliary machinery and its inventive concept, should be covered within the scope of protection of the present invention.
