Example 1
Fig. 1 is a schematic structural diagram of a system for converting and processing building information model data according to a first embodiment of the present invention, where the system can process BIM data efficiently and accurately, as shown in fig. 1, and includes: reactor, component library and connection library: the reactor sends an operation instruction to a component library, wherein the component library comprises an associated component for converting building information model BIM data; the component library starts all the associated components according to the operation instruction; and each associated component in the running state calls a matched connection unit from the connection library, and performs parallel conversion processing on the matched BIM data based on the connection unit.
Specifically, the component library includes a plurality of association components, for example, a file component, a data extraction component, a geometric entity component, a tissue tree component, a data creation component, a post-processing component, a read component, a write component, and the like, where the type of BIM data processed by the geometric entity component may be geometric and material data, the type of BIM data processed by the tissue tree component may be spatial tissue data, the type of BIM data processed by the data creation component may be attribute data, and of course, the present embodiment is merely illustrative, and the number and specific types of association components included in the component library are not limited, and each association component is specifically connected through a connection unit matched in the connection library. In this embodiment, the data processing flow may be packaged into components based on a pipeline filter model, so that a connection mode between the components may be autonomously organized when development is performed, so that the data conversion flow is configured, and a user may pre-configure the number, types and connection relations of related components in the component library according to actual needs, and in this embodiment, the specific configuration mode of the component library is not limited. The configuration mode can improve the multiplexing of the components, and the data processing conversion efficiency can be improved by the multithreading and data stream transmission modes.
It should be noted that before the reactor sends the operation instruction to the component library, dynamic expansion, modification, replacement and organization structure configuration of the components in the component library may be performed to obtain the associated components, where the modification may specifically be related operations such as component increase, decrease, connection, etc., that is, the component library is configurable, and in this embodiment, the specific configuration mode of the component library is not limited.
The processing system of this embodiment further includes a thread pool connected to the component library, and the thread pool includes a plurality of threads that are executed independently, and the specific number of threads included in the thread pool is not limited in this embodiment. Each component includes an output interface and an input interface, and the interfaces are connected in the form of pipes so as to form an overall data flow. And each component can asynchronously process data based on the thread pool while processing the data, and does not block message loops of the main thread.
The connection mode of the association component in the data non-heterogeneous scenario is shown in fig. 2, in which no converter component is required to be introduced to convert data, and the connection mode of the association component in the data heterogeneous scenario is shown in fig. 3, in which the converter component is required to be introduced to convert data. In this embodiment, only the interaction process of the components is illustrated in this embodiment, and the interaction manner of other associated components in the component library is approximately the same, so that no further description is given in this embodiment.
Optionally, the first association component in the component library determines a matched first connection unit from the connection library according to the configured output interface, and stores a first processing result of processing the matched first BIM data into a data queue of the first connection unit; a second association component adjacent to the first association component reads a first processing result from a data queue of the first connection unit according to the configured input interface, and takes the first processing result as BIM data matched with the second association component; the second association component processes the first processing result and synchronously processes the received matched second BIM data, wherein the second BIM data and the first BIM data are time sequence data, and the second BIM data are later than the first BIM data.
In a specific implementation, when the first association component is a read component and the second association component is a write component, and the connection relationship between the first association component and the second association component is shown in fig. 2 in a data non-heterogeneous scenario, a conversion processing interaction diagram of building information model data corresponding to the two components is shown in fig. 4. The reactor can respectively send an operation instruction run () to the read component and the write component, when the read component and the write component receive the operation instruction, the read component and the write component respectively detect the configuration conditions of the read component and the write component, and when the configuration is determined to be completed and the read component has the operation conditions, the read component can feed back a read data preparation completion instruction ReadAStarted () to the reactor, and meanwhile, the write component can feed back a write data preparation completion instruction noAvtiveJob () to the reactor. At this time, the reading component can obtain the first processing result after performing the reading operation and the corresponding processing according to the first BIM data input by the user on the interface, that is, the a data, and because the reading component only needs to complete the reading operation of the data, the a data can be directly used as the first processing result. As can be seen from fig. 2, since the output interface of the reading component is output port1, it can be determined that the output port1 is associated with the first connection unit connection1 according to the mapping relationship between the pre-configured data interface and the connection unit, at this time, the reading component stores the first processing result in the data queue of connection1, and when the first connection unit is stored, a storage completion message is fed back to the reading component, so that the reading component continues to read the subsequent second BIM data, i.e. B data, where both the a data and the B data are time sequence data, and the B data is later than the a data. In order to ensure that the read component and the write component keep running at all times, the reactor periodically sends running instructions, and when the feedback preparation work completion instructions of the read component and the write component are determined to be received, the read component and the write component can be determined to work normally, so that the reactor can know the working state of the components in time conveniently. When it is determined that the first processing result is stored in the data queue of connection1, since the input interface inport1 of the writing component is connected to the output interface outport1 of the reading component, the writing component sends a first processing result acquisition instruction receiveA () to the first connection unit through the input interface inport1, and performs a data writing operation write a () after receiving the a data fed back by the first connection unit. And when the writing component performs writing operation on the data A, the reading component can perform reading operation according to second BIM data input by a user on the interface, namely, the data B is subjected to corresponding processing to obtain a second processing result, and because the reading component only needs to complete the data reading operation, the data B can be directly used as the second processing result and sent to a data queue of the first connection unit connection1 through the output interface port 1. From the foregoing, it can be seen that fig. 4 shows an asynchronous execution mechanism based on a pipeline-filter model, and through an interaction process of a read component and a write component, it can be seen that after a reactor notifies the read component and the write component to execute tasks, data is transmitted in a first connection unit in a streaming manner, the components execute in a pipeline manner, the write component processes data a while the data B is processed by the data B, and each item of data is executed in parallel, so that higher data processing efficiency is achieved.
Optionally, the first association component processes the first BIM data based on the overall thread of the reactor to obtain a first processing result.
Optionally, the first association component sends a processing task to the thread pool, wherein the processing task includes first BIM data; the thread pool determines a target thread aiming at the processing task, processes the processing task by adopting the target thread to obtain a first processing result, and sends the first processing result to the first association component. In the present embodiment, when each associated component processes the matched BIM data, the corresponding processing result may be obtained by using a bus thread corresponding to the reactor or by using a thread in the thread pool, and the method of obtaining the corresponding processing result by each associated component is not limited in the present embodiment. Of course, the blocking of the total thread can be greatly reduced by adopting the mode of processing the threads in the thread pool. When it is determined that the first association component obtains the first BIM data and needs to process data based on threads in the thread pool, the first association component generates a processing task according to the first BIM data and sends a conversion processing task containing the first BIM data to the thread pool, the thread pool screens out a matched target thread according to the workload of the task, and when the task amount is large, the newly requested task needs to be queued for a spare thread because the working threads in the thread pool are all processing the task.
Optionally, when the first association component is further configured to determine that the first processing result is non-heterogeneous scene data, directly store the first processing result in a data queue of the first connection unit, so that the second association component reads the first processing result from the data queue of the first connection unit; when the first processing result is the heterogeneous scene data, the first processing result is converted by the converter component to obtain target data, and the target data is stored in a data queue of the second connection unit so as to be read by the second association component from the data queue of the second connection unit, wherein the second connection unit is matched with the converter component.
Optionally, the converter component queries the target data template file according to the first processing result to determine the data structure of the target data; calculating a first processing result according to a preset data conversion configuration to obtain the data content of the target number, wherein the data conversion configuration comprises a data calculation mode; target data is determined based on the data structure and the data content.
Specifically, in the heterogeneous data scenario, a converter component needs to be introduced, and data is converted by the converter component, as shown in fig. 3, that is, the processing result of the first association component is not directly sent to the second association component, but the first processing result is converted by the converter component and then sent to the second association component. For example, after the first association component saves the first processing result in the queue of the first association component connection1 through the matched output port1, the converter component reads the first processing result from the queue, processes the first processing result as source data to obtain target data, and saves the obtained target data in the queue of the second association component connection2 through the matched output port2, so that the second association component reads the target data from the queue.
It should be noted that the virtual table mechanism provided by the SQLite database of the converter in this embodiment directly accesses the structured BIM semantic data, supporting the SQL structured query language and CTE generic table expression. For example, when it is determined that the accessed source data is an array, for example, one of the arrays is (a, b, c, d, e), the data structure of the output target data is determined by looking up the pre-configured target data template file, for example, when it is determined that the data structure is (x, y, z) by looking up the target data template file, for example, the data structure of the target data is as shown in the following table 1:
TABLE 1
| x | y | z |
It can be seen from table 1 that only the data structure of the target data is known at this time, and the specific value of the target data is not known. However, since the data conversion configuration is set in advance, the structured data query is performed by reading the data conversion configuration, and the query result is mapped to the data table specified by the target data template file, so that the target data is output. Based on the configured data conversion mechanism, when the target data structure is changed, only the target data template file and the data conversion configuration are required to be adjusted, codes are not required to be adjusted, and program compiling is waited, so that the test period can be shortened, and the data conversion and delivery cost can be reduced. For example, for the source data (a, b, c, d, e), the data conversion configuration is described with (a×b+c, d+e, d/e), so that x=a×b+c, y=d+e, z=d/e can be obtained, and the above obtained values are added to table 1. Of course, in this embodiment, only the source data obtained by processing one item of data in the source data array is the same as the conversion processing manner of the other item of data in the array, and the description thereof will not be repeated in this embodiment.
It should be noted that, in addition to the above basic computing operation, the data computing manner in the data conversion configuration may also perform a series of operations such as connection, merging, counting, extremum taking, etc. on the data, or write a c++ language program custom data processing behavior based on the SQL language capability and the UDF custom function mechanism supported by the SQLite database. Of course, this embodiment is merely illustrative, and the specific type of data calculation mode is not limited.
It should be noted that the converter in this embodiment is mainly used for converting semantic data, matching heterogeneous data definitions and converting, and the conversion rule of the converter may be configured, which is merely illustrative, and the conversion rule of the converter is not specifically limited in this embodiment. In addition, the above data processing framework is mainly used for converting the BIM data in the form of a file into various data formats supported in the BIMBase platform, and supporting the whole flow of BIM data conversion. In addition to the semantic data conversion, the present application includes conversion of graphics data, conversion of texture data, conversion of model organization information, conversion of component type definition, and the like.
Optionally, each associated component in the component library is further configured to generate a fault prompt when determining that a blocking fault occurs, and send the fault prompt to the reactor; and the reactor is used for generating an operation stopping instruction according to the fault prompt and sending the operation stopping instruction to each associated component in the component library so as to stop the operation of each associated component.
In the process of receiving the operation instruction sent by the reactor and operating the associated components in the embodiment, when it is determined that a blocking fault occurs, a fault prompt is generated and sent to the reactor, for example, after it is determined that the first associated component has the blocking fault and sends the fault prompt to the reactor, since the output result of the first associated component cannot be obtained by the second associated component at the moment, the second associated component performs invalid operation, at the moment, the reactor sends an operation suspension instruction to the component library, and each associated component suspends operation according to the operation suspension instruction, thereby avoiding resource waste caused by invalid operation.
In the embodiment, all the association components in the component library are started through the reactor, and the association components process the matched BIM data by calling the connection component, so that the BIM data can be accurately and efficiently processed through the system.
Example two
Fig. 5 is a schematic diagram of a second embodiment of the present invention, where the present invention is applicable to a case of performing efficient and accurate processing on BIM data, and the method may be performed by the above-mentioned building information model data conversion processing system, as shown in fig. 5, and includes:
step S101, sending an operation instruction to the component library through the reactor.
The component library comprises association components of building information model BIM data. For example, the file component, the data extraction component, the geometric entity component, the organization tree component, the data creation component, the post-processing component, the reading component, the writing component, and the like are processed, wherein the BIM data processed by the geometric entity component can be of geometric and material data, the BIM data processed by the organization tree component can be of spatial organization data, the BIM data processed by the data creation component can be of attribute data, and of course, the number and the specific types of the association components contained in the component library are not limited, and the association components are specifically connected through the matched connection units in the connection library. In this embodiment, the data processing flow may be packaged into components based on a pipeline filter model, so that a connection mode between the components may be autonomously organized when development is performed, so that the data conversion flow is configured, and a user may pre-configure the number, types and connection relations of related components in the component library according to actual needs, and in this embodiment, the specific configuration mode of the component library is not limited. The configuration mode can improve the multiplexing of the components, and the data processing conversion efficiency can be improved by the multithreading and data stream transmission modes.
Step S102, starting all the associated components according to the operation instructions through the component library
After the reactor sends an operation instruction to the component library, each associated component in the component library starts to operate according to the operation instruction. The starting process of each associated component may refer to the interactive diagram of fig. 4, when the read component and the write component receive the operation instruction, the read component detects the configuration condition of the read component and the write component, and when the configuration is determined to be completed and the read component has the operation condition, the read component feeds back a read data preparation completion instruction ReadAStarted () to the reactor, and at the same time, the write component feeds back a write data preparation completion instruction noAvtiveJob () to the reactor. Of course, this embodiment is merely illustrative, and the specific form of the instruction fed back by each component is not limited.
Step S103, calling the matched connection units from the connection library through each associated component in the running state, and carrying out parallel processing on the matched BIM data based on the connection units.
Specifically, a first association component in the component library determines a matched first connection unit from the connection library according to the configured output interface, and stores a first processing result of processing the matched first BIM data into a data queue of the first connection unit; a second association component adjacent to the first association component reads a first processing result from a data queue of the first connection unit according to the configured input interface, and takes the first processing result as BIM data matched with the second association component; the second association component processes the first processing result and synchronously processes the received matched second BIM data, wherein the second BIM data and the first BIM data are time sequence data, and the second BIM data are later than the first BIM data. The first association component and the second association component in this embodiment may be any two associated components in the component library, and the types of the first association component and the second association component are not limited in this embodiment.
It should be noted that, the first association component processes the first BIM data based on the total thread of the reactor to obtain a first processing result. The first association component sends a processing task to the thread pool, wherein the processing task comprises first BIM data; the thread pool determines a target thread aiming at the processing task, processes the processing task by adopting the target thread to obtain a first processing result, and sends the first processing result to the first association component.
When each associated component processes the matched BIM data, the corresponding bus process of the reactor may be adopted, or the threads in the thread pool may be adopted to process the matched BIM data to obtain the corresponding processing result, and in this embodiment, the mode of obtaining the corresponding processing result by each associated component is not limited. Of course, the blocking of the total thread can be greatly reduced by adopting the mode of processing the threads in the thread pool. When it is determined that the first association component obtains the first BIM data and needs to process data based on threads in the thread pool, the first association component generates a processing task according to the first BIM data and sends a conversion processing task containing the first BIM data to the thread pool, the thread pool screens out a matched target thread according to the workload of the task, and when the task amount is large, the newly requested task needs to be queued for a spare thread because the working threads in the thread pool are all processing the task.
Optionally, the method further comprises: each associated component in the component library generates a fault prompt when determining that a blocking fault occurs, and sends the fault prompt to the reactor; the reactor generates an operation stopping instruction according to the fault prompt and sends the operation stopping instruction to each associated component in the component library so as to stop the operation of each associated component.
In this embodiment, in the process of receiving the operation instruction sent by the reactor and performing operation, when it is determined that a blocking fault occurs, a fault prompt is generated and sent to the reactor, for example, after it is determined that the first association component fails to block and sends the fault prompt to the reactor, since the second association component cannot acquire the output result of the first association component at this time, the second association component performs invalid operation, at this time, the reactor sends an operation suspension instruction to the component library, and each association component suspends operation according to the operation suspension instruction, thereby avoiding resource waste caused by invalid operation.
According to the embodiment of the invention, all the associated components in the component library are started through the reactor, and the associated components process the matched BIM data by calling the connecting component, so that the BIM data can be accurately and efficiently processed through the system.
It should be appreciated that various forms of the flows shown above may be used to reorder, add, or delete steps. For example, the steps described in the present invention may be performed in parallel, sequentially, or in a different order, so long as the desired results of the technical solution of the present invention are achieved, and the present invention is not limited herein.
The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives are possible, depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
