Description

Technical Field

[0001] The present invention relates to the technical field of construction project management, and particularly to an intelligent digital operation and maintenance system for equipment in large public construction projects based on the Internet of Things and BIM. Background Art

[0002] Large public construction projects include stadiums, libraries, museums, various memorial halls, etc. The main characteristics of such public construction projects are large floor areas, complex projects, and wide coverage, often requiring multiple construction sites to start work simultaneously and jointly promote the progress.

[0003] At this time, the problem of how to allocate resources among multiple construction sites is involved, including the sharing and scheduling of various mechanical and electrical equipment. For example, if Foundation Pit A and Foundation Pit B start construction simultaneously, and pile drivers are required at both adjacent foundation pits, how to reasonably arrange the sharing of mechanical and electrical equipment without significantly increasing costs is a problem that needs to be solved.

[0004] In the prior art, special dispatching personnel are usually arranged to coordinate the use of resources among multiple construction sites. However, in this way, the dispatching personnel cannot timely understand the real-time progress of each construction site, resulting in scheduling delays, and the idle time of each mechanical and electrical equipment cannot be fully utilized, and the efficiency is not high. Summary of the Invention

[0009] A BIM model, which is respectively connected to the acquisition module and the management and dispatching module, and is used for displaying the position information of each mechanical and electrical equipment, each group of parallel partitions, and the dispatching arrangement table.

[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] It can be understood that the terms "first", "second", etc. used in the present invention may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present invention, the first xx script may be referred to as the second xx script, and similarly, the second xx script may be referred to as the first xx script.

[0015] As Figure 1 shown, in an embodiment, an intelligent digital operation and maintenance system for large public construction project equipment based on the Internet of Things and BIM is proposed, which may specifically include:

[0016] A collection module, configured to obtain the location information and working status of each mechanical and electrical device through the Internet of Things technology;

[0017] A management and scheduling module, configured to divide the project based on the BIM model to obtain several groups of parallel partitions, and generate a scheduling arrangement table for the mechanical and electrical equipment according to the configuration information of each group of parallel partitions, the obtained location information and working status of the mechanical and electrical equipment;

[0018] The BIM model is respectively connected to the acquisition module and the management and scheduling module, and is used for displaying the position information of each mechanical and electrical equipment, each group of parallel partitions, and the scheduling arrangement table.

[0019] In this embodiment, the acquisition module includes an acquisition device and a data transmission device arranged on the mechanical and electrical equipment. Here, the acquisition device judges whether the motor equipment is in a working state or an idle state by obtaining the operation signal of the motor equipment, and sends the judged state of the mechanical and electrical equipment to the management and scheduling module through the data transmission device. Here, the data transmission device can be implemented by using conventional wireless modules such as a Bluetooth module, a wifi module, etc. This is a common communication module in the Internet of Things technology, and the present invention will not elaborate further on this. In this embodiment, the acquisition module uses the Internet of Things technology to obtain the working state and position information of each mechanical and electrical equipment. Among them, the position information can be obtained through the GPS module set on each mechanical and electrical equipment, and can also be realized through the communication between each mechanical and electrical equipment and the router. This is a common positioning method in the prior art, and the embodiments of the present invention will not elaborate further on this.

[0020] In this embodiment, the management and scheduling module divides the BIM model to obtain several groups of parallel partitions, and automatically generates a scheduling arrangement table for the mechanical and electrical equipment based on the division result and the information obtained by the acquisition module. The staff schedules the motor equipment by executing the scheduling arrangement table, which can realize the automatic generation of the scheduling plan, make full use of the idle time of the motor equipment, and improve the utilization rate of the mechanical and electrical equipment. In this embodiment, the parallel partition here refers to a partition where construction can be carried out simultaneously, and the partition refers to a specific construction area on the BIM model, that is, the building project. The present invention is mainly applied to large public building projects because large public building projects are often complex projects composed of multiple construction points, and mechanical and electrical equipment needs to be scheduled between each construction point; of course, it can also be applied to general building projects, rather than specifically in large public building projects. This belongs to an example rather than a limitation.

[0021] In this embodiment, the BIM model shows the overall situation of the large public building project. Using the BIM model, the specific positions of each mechanical and electrical equipment on the large public building project and the specific content of the scheduling arrangement table can also be shown in the form of documents, which is intuitive and easy to understand.

[0022] The intelligent digital operation and maintenance system for large public building projects based on the Internet of Things and BIM provided by the present invention uses a collection module to obtain the positions and status information of various mechanical and electrical devices through the Internet of Things technology. The BIM model is divided by the management and scheduling module, and based on the division results, as well as the obtained position information and working status of the mechanical and electrical devices, a scheduling arrangement table is automatically generated. Finally, through the BIM model, the positions of various mechanical and electrical devices, the division results of the BIM model, and the generated scheduling arrangement table are displayed, realizing the automatic arrangement of the scheduling of mechanical and electrical devices, making full use of the idle time of mechanical and electrical devices, improving the utilization rate of mechanical and electrical devices, being conducive to shortening the construction period, and saving costs.

[0023] As an optional embodiment of the present invention, the division of the project based on the BIM model to obtain several parallel areas includes:

[0024] Call the BIM model, establish an association between each component of the BIM model and the mechanical and electrical devices, and obtain the corresponding relationship between each component and the mechanical and electrical devices;

[0025] Divide the BIM model into several construction areas according to the corresponding relationship between each component and the mechanical and electrical devices;

[0026] Obtain at least one current construction position, and determine the construction area to which the current construction position belongs as the reference area;

[0027] Determine a group of parallel areas according to each reference area.

[0028] In this embodiment, establishing an association between each component of the BIM model and the mechanical and electrical devices is to divide the components of the BIM model to obtain components such as beams, walls, floor panels, and columns. According to the mechanical and electrical devices required for the construction process of each component, an association can be established between each component and the mechanical and electrical devices, thereby obtaining the corresponding relationship between each component and the mechanical and electrical devices.

[0029] In this embodiment, by dividing the construction areas of the BIM model, the progress of each area can be intuitively displayed, facilitating the arrangement and scheduling of mechanical and electrical devices according to the division results of the areas.

[0030] In this embodiment, the area to which the currently under-construction position belongs is used as the reference area, and the corresponding parallel areas are determined from the reference area to obtain a group of parallel areas. It should be understood that there can be multiple currently under-construction positions, that is, there can be multiple reference areas, thus obtaining multiple groups of parallel areas; each group of parallel areas is distinguished according to its reference area. Multiple parallel areas parallel to a reference area may be obtained from one reference area, and these multiple parallel areas form a group of parallel areas.

[0031] As an alternative embodiment of the present invention, dividing the BIM model into several construction zones according to the corresponding relationship between each component and the electromechanical equipment includes:

[0032] Classify the electromechanical equipment;

[0033] For each type of electromechanical equipment, determine all the components associated with it on the BIM model;

[0034] Among all the determined associated components, regard the components that are structurally connected to each other as a component group, and each type of electromechanical equipment corresponds to at least one component group;

[0035] Set a crossover threshold and an associated equipment threshold, and according to the crossover threshold and the associated equipment threshold, obtain several construction zones from the crossover and overlap relationships of the component groups;

[0036] Wherein, the number of component groups included in each construction zone takes the maximum value and is less than or equal to the crossover threshold, and the number of associated equipment included in each construction zone takes the maximum value and is less than or equal to the associated equipment threshold.

[0037] In this embodiment, the electromechanical equipment is classified according to the functions of the electromechanical equipment. For example, it can be specifically divided into excavation type, reinforcement type, general type, environmental maintenance type, etc.; of course, each type of electromechanical equipment can also be regarded as a class. The specific classification method has no essential influence on the implementation process of the present invention. The purpose of classification is to group the components according to the association relationship between the components and the electromechanical equipment, so as to determine the components that can be constructed simultaneously at a certain moment and the corresponding zones.

[0038] In this embodiment, the crossover threshold and the associated equipment threshold can be set as needed. Among them, the crossover threshold should be 5%-10% of the total number of all components at the same horizontal height, and the associated equipment threshold should be between 15%-25% of the total number of equipment classifications, so that the number of construction zones at the same horizontal height will not be too many or too few; reasonably controlling these two values can control the total amount of construction zones. Of course, the range of the total amount of construction zones can be set. When there is a deviation between the obtained total amount of construction zones and the set range, adjust these two values so that the total amount of construction zones falls within the set range. In this embodiment, when determining the construction zones, the total amount of construction zones can be regulated by the two set values, so that the size of the construction zones can be adjusted.

[0039] As an alternative embodiment of the present invention, determining a group of parallel zones according to each reference zone includes:

[0040] Screen out the zones that overlap with the reference zone in the height direction;

[0041] Among the selected partitions that overlap in the height direction, select the partitions that have no direct connection of components with the reference partition;

[0042] Among the selected partitions that have no direct connection of components with the reference partition, select the partitions that have at least one same mechanical and electrical equipment as the reference partition and the total number of such mechanical and electrical equipment in the reference partition and the selected partitions is less than or equal to the available value of the corresponding mechanical and electrical equipment, so as to obtain a set of parallel partitions corresponding to the reference partition.

[0043] In this embodiment, the partitions that overlap with the reference partition in the height direction refer to that the height dimensions of the components included in the two partitions overlap. For example, the height of component 1 in partition 1 is 10 meters to 12 meters (relative to the same reference, such as sea level, foundation pit plane, etc.), and the height of component 1 in partition 2 is 9.8 meters to 10.4 meters. Then there are components that overlap in the height direction between the two partitions, and the two partitions overlap in the height direction. In this embodiment, partitions are screened through the overlapping area, so that the division of parallel partitions can closely follow the construction progress, and the obtained parallel partitions are basically maintained on the same horizontal construction surface, realizing parallelism in construction.

[0044] In this embodiment, selecting the partitions that have no direct connection of components with the reference partition can avoid the existence of a construction sequence between the two partitions due to the association of components in adjacent partitions, making it impossible to achieve parallelism.

[0045] In this embodiment, for example, both the reference partition and another partition need to use water pumps. However, the number of water pumps required for the reference partition is 8, and the number of water pumps required for the other partition is 4. The total number of water pumps required by both is 12, which exceeds the total existing number of water pumps, which is 10. Then these two partitions cannot be used as parallel partitions.

[0046] As an optional embodiment of the present invention, generating a scheduling arrangement table for mechanical and electrical equipment according to the configuration information of each group of parallel partitions, the obtained position information and working status of mechanical and electrical equipment includes:

[0047] According to the configuration information of each partition within each group of parallel partitions, merge the start and end times of each reference partition and its corresponding parallel partitions to obtain the start and end time ranges of each group of parallel partitions;

[0048] Establish several time axes according to the number of construction points of the project, and represent the start and end time ranges of each group of parallel partitions on the corresponding time axes;

[0049] Determine the mechanical and electrical equipment required for each group of parallel partitions according to the configuration information of each partition within each group of parallel partitions;

[0050] Allocate electromechanical equipment to each parallel partition according to the start times of each group of parallel partitions and the total amount of electromechanical equipment;

[0051] Generate a scheduling arrangement table for each electromechanical equipment based on the allocation results, the current position information, and the working status of the electromechanical equipment.

[0052] In this embodiment, the configuration information of each group of parallel partitions includes the required electromechanical equipment for each partition, the construction site to which each partition belongs, the planned start time and the planned completion time of each partition, etc. The basic information of the parallel partition can be obtained from the configuration information of each parallel partition, and these basic information have been determined when the BIM model is constructed.

[0053] In this embodiment, a parallel partition means that construction can be carried out simultaneously between two partitions. Therefore, there must be overlapping time periods in the construction time of parallel partitions. In this embodiment, the start and end time ranges are determined according to the start and end times of each group of parallel partitions. For example, the construction period of partition one is from the 5th to the 8th of a certain month, the construction period of partition two is from the 4th to the 9th of the same month, and the construction period of partition three is from the 7th to the 11th of the same month. Then the start and end times of a group of parallel partitions composed of these three partitions are from the 4th to the 11th of this month, and this time includes the start and end times of all partitions in the same group of parallel partitions.

[0054] In this embodiment, when the project has two construction sites, two time axes are established, and the start and end times of each parallel partition are represented on the time axis of the corresponding construction site. Allocate electromechanical equipment to each group of parallel partitions according to the start times of each group of parallel partitions from the earliest to the latest, and generate a height arrangement table based on the allocation results. In this embodiment, multiple time axes are established to distinguish the parallel partitions of different construction sites in time and avoid time overlap of partitions at different construction sites. For example, the process of allocating equipment can be as follows: the total number of mixers is 20, the start time of the first partition is the earliest and it requires 9 mixers, the start time of the second partition is the second earliest and it requires 12 mixers. Then allocate 9 mixers to the first partition first, and then allocate 11 mixers to the second partition.

[0055] As an alternative embodiment of the present invention, the generating a scheduling arrangement table for each electromechanical equipment based on the allocation results, the current position information, and the working status of the electromechanical equipment includes:

[0056] Determine the electromechanical equipment to be scheduled according to the allocation results and the current position information of the electromechanical equipment;

[0057] Obtain the working status of the electromechanical equipment to be scheduled, and schedule the electromechanical equipment with the working status of idle to the nearest parallel partition according to the principle of the shortest path;

[0058] Monitor the working status of each electromechanical device to be scheduled until the working status is idle;

[0059] Generate a scheduling notice;

[0060] Generate a scheduling arrangement form according to the above steps.

[0061] In this embodiment, determine the electromechanical devices that need to be scheduled according to the allocation result and the current position of the electromechanical devices, and perform scheduling according to the above steps. In this embodiment, it should be noted that the system provided by the present invention needs to monitor the project progress in real time (which can be entered by designated personnel), and monitor and schedule the electromechanical devices in real time according to the progress of each part of the project. This is because the generated scheduling plan or construction progress usually cannot be accurately completed according to the scheduled time. Therefore, by dynamically and repeatedly applying the system provided by the present invention, dynamic scheduling of electromechanical devices can be achieved, making the use of electromechanical devices in the entire project always close to the maximum utilization rate, thereby accelerating the project progress and reducing the time cost.
