Description
Technical Field

Background
Building Information Modeling (BIM) is continuously extended from Building design and construction to Building operation and maintenance management, which inevitably requires the problem that the BIM is integrated with a large number of existing intelligent systems in a Building, that is, thousands of internet of things data points existing in a Building need to be associated with model objects such as equipment or space in the BIM.
In most of the existing processes, engineers generally use Excel-based table work to edit a point location table and then upload the point location table to a background database, or use single-point configuration editing, that is, a computer visualization interface is used to make data points and an existing data table of the database correspond to model objects in a BIM model, such as equipment or space, one by one.
The method for editing the Excel table is high in flexibility, but most field engineers cannot master some advanced editing functions in the Excel tool and still can edit the Excel table one by one only by a single point, so that the final working efficiency is not high; secondly, automatic conversion of data formats sometimes occurs in the Excel tool, for example, original data is a string of numbers "0123", but the format is character type, and the original data is imported into Excel to convert into numbers 123 by default, and the formats are easy to change to cause errors of subsequent table processing and data storage; in addition, the situation that management data is edited under the off-line condition is difficult to be put away by the working mode, so that the problem that the data in the cloud database and the off-line profile data are not synchronous is caused; due to human misoperation, the error of data asynchronization is easy to generate.
The single-point configuration editing method has a large workload, for example, for a public building with 10 ten thousand square meters, the number of point locations may reach 3 ten thousand, the number of devices may reach 4 thousand, 3 ten thousand points are corresponded to 4 thousand devices one by one, the workload is large, errors are easy to occur, and the checking is not easy after the errors occur, so that the overall engineering efficiency is extremely low.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for associating data with a model according to an embodiment of the present invention, where the embodiment is applicable to a case where data of an internet of things is associated with a model object, such as a device or a space, in a BIM model, and the method may be executed by a device for associating data with a model, where the device may be implemented in a software and/or hardware manner, and the device may be integrated in a processor in a computer, as shown in fig. 1, and the method specifically includes:
s110, acquiring a point location table of data from an Internet of things database, and determining a point location name/description list from the point location table;
fig. 2 is a schematic diagram of a dot bit table according to an embodiment of the present invention. As shown in fig. 2, the point location table may be obtained from an internet of things database, or may be obtained by interfacing with a supplier or an implementer of the intelligent system. The point location table may include point location description information according to field implementation. For example, the point location Description information may include a point location name/Description (Description), such as "chilled water supply temperature of # 1 chiller"; point location Data types (Data types), such as, for example, pool, int, double, str, etc.; a value specification (not shown in fig. 2), for example, 0 is "off", and 1 is "on"; physical units (not shown in fig. 2), such as c, m3/h, MPa, etc., and point to point communication addresses, etc.
In an implementation manner of the embodiment of the present invention, optionally, determining the point location name/description list from the point location table may include: determining point location description information from a point location table; a point location name/description list is determined from the point location description information.
As shown in fig. 2, point location Description information may be determined from the point location table, and a column of point location Description information as a point location name/Description (Description) is extracted to generate a point location name/Description list. The point location name/description list includes a plurality of point location name/description fields, and each point location name/description field may correspond to data of the internet of things. For example, the point location name/description field may correspond to internet of things data such as a point location communication address, a point location value, a point location data type, a value description, and a physical unit. For example, the point location name/description field is "1 # cooling pump start order", and the corresponding internet of things data may be the point location communication address "17", the point location value "3.000000", and the point location data type "Float".
S120, determining a main body type field, a parameter type field and an instance sequence number field in each point name/description field in the point name/description list;
wherein, each point bit name/description field can be composed of a body type field, a parameter type field and an instance sequence number field. The body type field may be the name of a device or space used in the actual engineering, such as a refrigerator, a freezing pump, or a cooling tower; the parameter type field can be a data type required by equipment or space, such as a starting sequence, a difference between a water supply temperature and a set value, a water supply and return temperature difference, a water supply and return pressure difference, a water return temperature setting, a load requirement, the number of equipment or a water return flow and the like; the instance number may represent a number of devices or spaces, and may be composed of positive integers and set symbols, e.g., 1#, 2#, 3#, etc. For example, the point name/description field is "chilled water supply temperature of 1# chiller", the body type field is "chiller", the parameter type field is "chilled water supply temperature", and the instance number field is "1 #".
In an implementation manner of the embodiment of the present invention, optionally, determining a body type field, a parameter type field, and an instance sequence number field of each point name/description field in the point name/description list includes: acquiring a current specified characteristic field, wherein the specified characteristic field comprises a specified main body type field, a specified parameter type field or a specified instance sequence number field; checking whether each point bit name/description field contains a current specified characteristic field; if yes, judging whether a characteristic field in each point bit name/description field is empty or not, wherein the characteristic field comprises a main body type field, a parameter type field or an instance sequence number field; if the designated characteristic field of each point name/description field is not empty, covering the non-empty designated characteristic field by using the current designated characteristic field; and if the characteristic field of each point bit name/description field is empty, taking the current specified characteristic field as the characteristic field of the point bit name/description field.
Wherein, optionally, the field for specifying the type of the subject includes at least one of a water chilling unit, a freezing pump, a cooling tower, cooling water or chilled water; the specified parameter type field comprises at least one of the difference between the water supply temperature and a set value, the temperature difference between the water supply and the water return, the pressure difference between the water supply and the water return, the setting of the water return temperature, the load requirement, the number of the units, the water return flow or the starting sequence; the specified instance sequence number field refers to a field consisting of a positive integer and a set symbol.
Specifically, the current specified feature field may be specified as a specified body type field, and it is checked whether the name/description field of each point contains the current specified body type field. If yes, judging whether a main body type field in each point bit name/description field is empty; if not, covering the non-empty body type field with the current specified body type field; if the point location name/description field is empty, the current specified body type field is used as the body type field of the point location name/description field. If not, the body type field of the entry point bit name/description field may be left unchanged.
It should be noted that the current specified feature field is a body type field, wherein the specified body type field may be one or more of a water chiller, a refrigeration pump, a cooling tower, cooling water, or chilled water; after the body type field in each point name/description field in the point name/description list is checked, a next body type field can be designated as a current designated body type field, and whether the current designated body type field is contained in each point name/description field is checked again until all preset body type fields are designated.
In an example, the point name/description list includes 2 point name/description fields of "1 # chiller chilled water supply temperature" and "number of chiller required cooling towers". If the current specified body type field is specified as the "water chilling unit", the body type field of the "1 # water chilling unit frozen water supply temperature" is the "water chilling unit"; while the body type field for "number of cold-required cooling towers" remains unchanged. At this time, if the currently specified subject type field is specified as "cold", the subject type field of the "chilled water supply temperature of # 1 chiller" is kept unchanged, i.e., "chiller", and the subject type field of the "number of towers that the cold requires" is "cold". If the currently specified subject type field is designated as "cooling tower", the subject type field of "chilled water supply temperature of # 1 chiller" is kept unchanged, i.e., "chiller", and the subject type field of "number of chillers requiring cooling towers" is overwritten with "cooling tower". This process may be repeated until all of the predetermined specified subject type fields have been specified, or none of the subject type fields of each bit name/description field are empty.
In the embodiment of the present invention, the current specified feature field can be specified as the specified parameter type field, and whether the current specified parameter type field is contained in the name/description field of each point bit is checked. If yes, judging whether a parameter type field in each point bit name/description field is empty; if not, covering the non-empty parameter type field by using the current specified parameter type field; and if the current specified parameter type field is empty, the current specified parameter type field is used as the parameter type field of the point location name/description field. If not, the parameter type field of the entry point bit name/description field may be left unchanged.
It should be noted that, for the current designated parameter type field, the designated parameter type field may include one or more of a difference between a water supply temperature and a set value, a water supply and return temperature difference, a water supply and return pressure difference, a water return temperature setting, a load demand, a number of sets, a water return flow rate, or a start sequence; after the parameter type fields in each point name/description field in the point name/description list are checked, the next specified parameter type field can be specified as the current specified parameter type field, and whether the specified parameter type fields are contained in each point name/description field is checked again until all the preset specified parameter type fields are specified.
For example, the site name/description list includes 2 site name/description fields of "number of cold-required cooling towers" and "1 # cooling pump start sequence". If the currently specified parameter type field is specified as "startup sequence", the parameter type field of "1 # cooling pump startup sequence" is the "startup sequence", and the parameter type field of "number of cold-required cooling towers" remains unchanged. If the currently specified parameter type field is specified as "number of stages", the parameter type field of "number of stages required for cooling by refrigerator" is "number of stages", and the parameter type field of "start sequence of # 1 cooling pump" is left unchanged, i.e., "start sequence". This process may be repeated until all of the predetermined specified parameter type fields have been specified, or until none of the parameter type fields of the bit name/description field are empty.
In the embodiment of the present invention, the current specified feature field can be specified as the specified instance number field, and whether the current specified instance number field is contained in the name/description field of each point bit is checked. If yes, judging whether an example sequence number field in each point bit name/description field is empty; if not, the current appointed example sequence number field is adopted to cover the non-empty example sequence number field; if it is null, the current specified instance sequence number field is used as the instance sequence number field of the point location name/description field. If not, the instance sequence number field of the entry point bit name/description field may be left unchanged.
It should be noted that, for the current designated instance sequence number field, the designated instance sequence number field may refer to a field composed of a positive integer and a set symbol; after the example sequence number fields in each point name/description field in the point name/description list are checked, the next specified example sequence number field can be designated as the current specified example sequence number field, and whether the specified example sequence number fields are contained in each point name/description field is checked again until all the preset specified example sequence number fields are designated.
For example, the site name/description list includes 2 site name/description fields of "1 # cooling pump start sequence" and "2 # cooling pump start sequence". If the currently specified instance number field is designated as "1 #", then the instance number field of the "1 # cooling pump startup sequence" is "1 #", while the instance number field of the "2 # cooling pump startup sequence" remains unchanged. If the currently specified instance number field is designated as "2 #", then the instance number field of the "1 # cooling pump startup sequence" remains unchanged, i.e., "1 #", while the instance number field of the "2 # cooling pump startup sequence" is "2 #". This process may be repeated until all of the predetermined specified instance sequence number fields have been specified, or until none of the instance sequence number fields of each point bit name/description field are empty.
It should be further noted that, the determination process of the main type field, the parameter type field, and the instance sequence number field of each point name/description field in the point name/description list may be performed simultaneously or separately, but the order of the main type field, the parameter type field, and the instance sequence number field is not limited in the present invention.
In an implementation manner of the embodiment of the present invention, optionally, when a local adjustment instruction is received, it is determined whether a main body type field, a parameter type field, and an instance sequence number field in each point bit name/description field respectively match a historical adjustment record of a specified main body type field, a specified parameter type field, and a specified instance sequence number field; if not, replacing the corresponding unmatched item in the point location name/description field with the specified main body type field, the specified parameter type field or the specified instance sequence number field of the history adjustment record.
After determining the main body type field, the parameter type field and the instance sequence number field of each point name/description field in the point name/description list, receiving a local adjustment instruction, and locally adjusting the main body type field, the parameter type field and the instance sequence number field of the point name/description field, so that the main body type field, the parameter type field and the instance sequence number field of the determined point name/description field are correct. The history adjustment record can be a field for specifying a body type, a field for specifying a parameter type and a field for specifying an instance sequence number, which are adjusted once or are easy to generate errors. For example, the point location name/description field is "number of cooling towers needed by a refrigerator", and when the current specified subject type field is specified as "refrigerator", the subject type field is "refrigerator"; and when the currently specified body type field is re-specified as "cooling tower", its body type is overwritten as "cooling tower". However, the body type field of "number of cooling towers required for a chiller" is actually "chiller". At this time, the specified subject type field "cold" may be used as an entry of the history adjustment record. And judging that the main body type field in the number of the cooling towers needed by the cold machine is the cooling tower and is not matched with the cold machine in the historical adjustment record, and replacing the main body type field in the number of the cooling towers needed by the cold machine with the cold machine.
Fig. 3 is a flowchart for determining a feature field of each point location name/description field in the point location name/description list according to an embodiment of the present invention. As shown in fig. 3, a point location name/description list may be obtained first, and the point location name/description list may have multiple point location name/description fields; then, the current specified characteristic field can be specified, and the specified characteristic field can comprise a specified main body type field, a specified parameter type field and a specified instance sequence number field; each point bit name/description field may be checked for the presence of a current specified feature field; if yes, judging whether a characteristic field in each point bit name/description field is empty or not, wherein the characteristic field comprises a main body type field, a parameter type field or an instance sequence number field; if the name/description field of each point bit is not empty, covering the non-empty characteristic field by using the current specified characteristic field; if each point location name/description field is empty, taking the current specified characteristic field as the characteristic field of the point location name/description field; if the point location name/description field does not contain the current specified feature field, the feature field of the point location name/description field is kept unchanged. After the current designated feature field is checked, the next designated feature field can be designated as the current designated feature field until all designated feature fields are designated. After the body type field, the parameter type field and the instance sequence number field of each point name/description field in the point name/description list are determined, a local adjustment instruction is received, and the body type field, the parameter type field and the instance sequence number field of the point name/description field are adjusted locally, so that the body type field, the parameter type field and the instance sequence number field of the determined point name/description field are correct.
The flowchart for determining the body type field, the parameter type field, and the instance sequence number field of each point name/description field in the point name/description list may refer to fig. 4. Fig. 4 is a flowchart for determining a feature field of each point location name/description field in the point location name/description list according to an embodiment of the present invention. As shown in fig. 4, the current specified feature field str may be specified to sequentially retrieve all point location name/description fields Li in the point location name/description list { Li }. Judging whether str is contained in Li, if not, judging the next Li, and if so, judging whether the characteristic field of the Li is empty; if the str is empty as the feature field of Li, if the str is not empty, other specified feature fields already existing in Li are overwritten. As shown in FIG. 4, after the characteristic field of Li in { Li } is determined, a local adjustment instruction may be received to locally adjust the characteristic field of Li, so that the determined characteristic field of Li is correct. It is also possible to make local adjustments only for the point location name/description field that the feature field is covered. The workload can be reduced, and the characteristic field determination of the point location name/description field can be realized quickly.
And S130, correspondingly matching the main body type field in each point name/description field with the name of a type of model object in the BIM.
The main body type field in the point location name/description field is correspondingly matched with the name of a type of model object in the building information model BIM, so that each point location name/description field can be respectively associated with the corresponding type of model object in the BIM. The model object of one type can be a device family or a space class, and the embodiment of the invention is suitable for matching the device family or the space class in the BIM and the data of the Internet of things. The equipment family can be a plurality of pieces of equipment of the same type, for example, a plurality of centrifugal coolers exist in the BIM model, all the centrifugal coolers can be called as an equipment family named as 'centrifugal coolers', the equipment family belongs to a class of model objects, and a main body type field 'water chilling unit' can be correspondingly matched with all the centrifugal coolers named as 'centrifugal coolers' in the BIM model. The space class may be a plurality of spaces of the same type, and the space may be an object of a non-device family having a spatial dimension in the BIM model, such as a room, a sump, and the like. For example, there are a plurality of slops in the BIM model, all of which may be referred to as a space class named "slop", belong to a class of model objects, and the body type field "slop" may be correspondingly matched with all of the slops named "slop" in the BIM model. The model object in the BIM model can be a device family or a space class, and the correlation between the model object and the data of the Internet of things can be realized by adopting the method provided by the embodiment of the invention.
And S140, correspondingly matching the parameter type field and the instance sequence number field in the point name/description field of each item with the parameter type and the instance sequence number of a type of model object in the BIM respectively based on the matching result of the body type.
The matching of the subject type can be realized, and the subject type field in the point location name/description field is correspondingly matched with the name of one type of model object in the BIM. Based on the result, the parameter type field and the instance sequence number field in the point location name/description field are respectively and correspondingly matched with the parameter type and the instance sequence number of the class of model object in the BIM, that is, the parameter type and the instance sequence number of the class of model object which is already matched, such as a certain class of equipment family or space class, are correspondingly matched. It can be convenient to implement that each dot-bit name/description field can be respectively associated with a matching item of a corresponding device or space in the BIM model, wherein the matching item can be formed by the name, parameter type and instance serial number of a class of model object in the BIM model. For example, a class model object is a certain class of equipment family, and the main body type field "water chilling unit" can be correspondingly matched with the equipment family "centrifugal chiller" in the BIM model; correspondingly matching the parameter type field 'chilled water supply water temperature' with the parameter type 'CHW-Temp' corresponding to the equipment family named 'centrifugal chiller' in the BIM model; and correspondingly matching the example serial number field '1 #' with the example serial number 'CH 01' corresponding to the equipment family named 'centrifugal cooler' in the BIM model. The first-class model object is a certain class of space class, and a main body type field 'sump' can be correspondingly matched with the space class 'sump' in the BIM model; correspondingly matching the parameter type field 'Water temperature' with a parameter type 'Water-Temp' corresponding to a space class named 'sump' in the BIM model; and correspondingly matching the example serial number field '1 #' with the example serial number 'WW 01' corresponding to the space class named 'sump' in the BIM model. The corresponding matching between the main body type field and the name is before, the corresponding matching between the parameter type field and the parameter type and the corresponding matching between the instance sequence number field and the instance sequence number are after, and the corresponding matching between the parameter type field and the parameter type and the corresponding matching between the instance sequence number field and the instance sequence number may not be in order. The matching can be that all fields are subjected to word segmentation operation by adopting dictionary search, maximum probability segmentation, a hidden Markov model, a Viterbi algorithm and the like to generate keywords; generating a word segmentation dictionary by using the numbers and the keywords; and (3) replacing the two fields with the number combinations respectively, and judging the number of codes of the first field in the second field and the total number of codes of the second field in the two fields needing to be matched, wherein the ratio of the two numbers is the similarity. The two fields with the highest degree of similarity may be selected for matching. At this time, the point location name/description field "chilled water supply temperature of # 1 chiller" may be associated with the "CHW-Temp" matching item of the centrifugal chiller with the example serial number "CH 01" in the BIM model; the point location name/description field "1 # sump Water temperature" may be associated with the "Water-Temp" matching item of the sump with the example serial number "WW 01" in the BIM model.
One use process of the embodiment of the invention can be as follows: for a point location table obtained by docking from an internet of things database or with a supplier or an implementer of an intelligent system, point location description information contained in the point location table can be obtained, and a point location name/description can be obtained from the point location description information; the column corresponding to the point location name/description in the point location table may be extracted to generate a point location name/description list. The point location name/description list includes a plurality of point location name/description fields, for example, the point location name/description fields are: "1 # water chilling unit freezing water supply temperature".
