[0120] The following sections will explain the cases of extracting similar machine data points from machine data points of multiple machines and the cases of extracting common data points similar to machine data points of a new machine.

[0121] First, let's explain the situation of extracting similar machine data points from machine data points of multiple machines.

[0122] [Extracting similar machine data points from machine data points of multiple machines]

[0123] The machine data point acquisition unit 101 obtains the machine's description of machine data points from the machine's communication specification.

[0124] Specifically, the machine data point acquisition unit 101 acquires data from the machine's communication specification (for example, digitized data if the communication specification is paper), and obtains a description of the machine's data points from the data in the communication specification (for example, descriptions of the machine data point's name, definition, read / write permissions, or unit, etc.).

[0125] [Communication Specification]

[0126] Figure 4This is an example of a communication specification for a machine according to an embodiment of the present invention. The machine's communication specification describes the specifications when the machine uses a communication protocol (e.g., BACnet). The machine data point acquisition unit 101 obtains data from... Figure 4 The data from the communication specification document is used to obtain descriptions of machine data points. For example, a description of a machine data point includes at least one of the following: the name of the machine data point, a description of its definition, read / write permissions, and the unit of measurement. Furthermore, Figure 4 It can be expressed in Japanese, but it can be any language such as English.

[0127] Back Figure 3 Explanation.

[0128] The first extraction unit 102 extracts similar machine data points from machine data points of multiple machines. For example, the following situation is described: similar machine data points are extracted from machine data points of the first machine (machine A) and the second machine (machine A′). For example, machine A and machine A′ are the same type (type a), but different models.

[0129] Specifically, the first extraction unit 102 extracts common data points common to multiple machines (i.e., machine data points of the first machine (machine A) and machine data points of the second machine (machine A') based on whether the description of machine data points of the first machine (machine A) and the description of machine data points of the second machine (machine A') are similar (e.g., at least one of the following: the name of the machine data point, the description of the definition of the machine data point, the read / write permissions of the machine data point, or the unit of the machine data point).

[0130] For example, the first extraction unit 102 performs natural language processing on the names of machine data points of the first machine (machine A) and the names of machine data points of the second machine (machine A′), and extracts common data points based on their similarity (for example, the machine data points of the first machine (machine A) and the machine data points of the second machine (machine A′) with a similarity of more than a threshold are taken as common data points).

[0131] For example, the first extraction unit 102 performs natural language processing on the definition descriptions of the machine data points of the first machine (machine A) and the definition descriptions of the machine data points of the second machine (machine A'), and extracts common data points based on the similarity between the two (for example, the machine data points of the first machine (machine A) and the machine data points of the second machine (machine A') with similarity above a threshold are taken as common data points).

[0132] For example, the first extraction unit 102 performs natural language processing on the read / write permissions or units of machine data points of the first machine (machine A) and the read / write permissions or units of machine data points of the second machine (machine A'), and extracts common data points based on the similarity between the two (for example, the machine data points of the first machine (machine A) and the machine data points of the second machine (machine A') with a consistency of more than a threshold are taken as common data points).

[0133] Reference Figure 5 and Figure 6 This section provides a detailed explanation of how to determine the similarity of machine data points.

[0134] Figure 5 This is a diagram illustrating the similarity judgment of the definition of machine data points according to one embodiment of the present invention. The first extraction unit 102 calculates a certain machine data point of the first machine (machine A) (for example, Figure 5 The first extraction unit 102 calculates the similarity between the definition description of data point 1) and the definition description of each machine data point of the second machine (machine A'). Next, the first extraction unit 102 calculates the similarity between the definition description of the other machine data points of the first machine (machine A) and the definition description of each machine data point of the second machine (machine A'). Figure 5 The first extraction unit 102 calculates the similarity between the definition description of data point 2) and the definition description of each machine data point of the second machine (machine A'). Similarly, the first extraction unit 102 calculates the similarity for all machine data points of the first machine (machine A).

[0135] Figure 6 This diagram illustrates the similarity determination of read / write permissions for machine data points according to one embodiment of the present invention. The first extraction unit 102 calculates a specific machine data point (e.g., ...) of the first machine (machine A). Figure 6 The first extraction unit 102 calculates the similarity between the read / write permissions of data point 1) and the read / write permissions of each machine data point of the second machine (machine A'). Next, the first extraction unit 102 calculates the similarity between the read / write permissions of other machine data points of the first machine (machine A) and the read / write permissions of each machine data point of the second machine (machine A'). Figure 6 The first extraction unit 102 calculates the similarity between the read / write permissions of data point 2) and the read / write permissions of each machine data point of the second machine (machine A'). Similarly, the first extraction unit 102 performs similarity calculations on all machine data points of the first machine (machine A).

[0136] Thus, in one embodiment of the present invention, common (i.e. similar) machine data points that are common to multiple machines of the same type can be used as common data points.

[0137] Back Figure 3 Explanation.

[0138] The association information generation unit 103 generates information that associates the machine data points of each of the multiple machines (i.e., the machine data points of the first machine (machine A) and the machine data points of the second machine (machine A′)) with the common data points extracted by the first extraction unit 102.

[0139] [Related Information]

[0140] Figure 7 This is an example of association information (information generated by the association information generation unit 103) of machine data points of multiple machines according to an embodiment of the present invention. The association information of machine data points of multiple machines is information indicating that the machine data points of a first machine and the machine data points of a second machine have similar descriptions of the machine data points (that is, information indicating which machine data point of the first machine and which machine data point of the second machine are similar).

[0141] Back Figure 3 Explanation.

[0142] The association information generation unit 103 displays common data points (i.e., machine data points of the first machine and machine data points of the second machine, which are common data points) on the user terminal 20 or the association information generation device 10 (for example, displaying...). Figure 12 The image (of which the image is located) can receive instructions from the user to determine common data points. Furthermore, the association information generation unit 103 can receive instructions from the user to output common data points and output common data points.

[0143] Furthermore, the association information generation unit 103 can generate a description of common data points and generate information that associates machine data points of each machine. Specifically, the association information generation unit 103 can generate information that associates the description of common data points with the descriptions of machine data points of each machine. For example, the association information generation unit 103 can generate a description of common data points based on instructions from a user, or it can generate a description of common data points based on machine data points of each machine (without instructions from a user). For example, the description of common data points includes at least one of the following: the name of the common data point, a description of the definition of the common data point, read / write permissions of the common data point, and the unit of the common data point. Thus, in one embodiment of the present invention, common data points common to multiple machines of the same type can be associated with machine data points of each of the multiple machines. The association information generation unit 103 can output information that associates common data points with machine data points of each of the multiple machines (e.g., displaying on an image, printing, sending data), or store it in any database (e.g., the database within the association information generation device 10).

[0144] Next, we will explain the extraction of common data points similar to the machine data points of the new machine.

[0145] [Extraction of common data points similar to machine data points of the new machine]

[0146] The machine data point acquisition unit 101 obtains the machine's description of machine data points from the machine's communication specification.

[0147] For example, when the machine data point acquisition unit 101 adds a new machine (as the third machine (machine X)) to an existing building management system, it acquires a description of the machine data points of the new machine (the third machine (machine X)). For example, the third machine (machine X) is the same type (type a) as the first machine (machine A) and the second machine (machine A′), but the model number is different.

[0148] The common data point acquisition unit 104 acquires the description of common data points (e.g., common data points for model a) stored in the common data point storage unit 106. For example, the user can specify the desired model.

[0149] The common data point storage unit 106 stores data describing common data points. As described above, the association information generation device 10 can generate descriptions of common data points and store them in the common data point storage unit 106 based on instructions from the user, or it can generate descriptions of common data points and store them in the common data point storage unit 106 based on machine data points of each machine (without instructions from the user).

[0150] [Common Data Points]

[0151] Figure 8 This is an example of a description of common data points (the description of common data points stored in the common data point storage unit 106) according to an embodiment of the present invention. In the specifications of a building management system (BMS), descriptions of common data points are created for multiple machines (e.g., for each machine type). For example, the description of a common data point includes at least one of the following: the name of the common data point, a description of its definition, read / write permissions, and the unit of the common data point. Furthermore, Figure 8 It is expressed in Japanese, but can be any language such as English.

[0152] Back Figure 3 Explanation.

[0153] The second extraction unit 105 extracts common data points that are similar to the machine data points of the third machine (machine X) based on whether the description of common data points is similar to the description of machine data points of the third machine (machine X) (e.g., including at least one of the following: name, description of machine definition, read / write permissions, or unit).

[0154] For example, the second extraction unit 105 performs natural language processing on the names of the machine data points and common data points of the third machine (machine X), and extracts common data points that are similar to the machine data points of the third machine (machine X) based on their similarity (for example, extracting common data points with a similarity of more than a threshold).

[0155] For example, the second extraction unit 105 performs natural language processing on the definition descriptions of the machine data points of the third machine (machine X) and the definition descriptions of common data points, and extracts common data points similar to the machine data points of the third machine (machine X) based on the similarity between the two (for example, extracting common data points with a similarity of more than a threshold).

[0156] For example, the second extraction unit 105 performs natural language processing on the read / write permissions or units of machine data points of the third machine (machine X) and the read / write permissions or units of common data points, and extracts common data points similar to the machine data points of the third machine (machine X) based on the similarity between the two (for example, extracting common data points with a consistency of more than a threshold).

[0157] Reference Figure 9 and Figure 10 This section provides a detailed explanation of how to determine the similarity between common data points and machine data points.

[0158] Figure 9 This diagram illustrates the similarity determination of the names of common data points and machine data points according to one embodiment of the present invention. The second extraction unit 105 calculates a certain data point of the common data point (e.g., Figure 9 The similarity between the name of data point 1) and the names of the machine data points of the third machine (machine X). Next, the second extraction unit 105 calculates the similarity between other data points of common data points (e.g., Figure 9 The similarity between the name of data point 2) and the names of machine data points of the third machine (machine X) is calculated. Similarly, the second extraction unit 105 performs similarity calculations on all data points with common data points.

[0159] Figure 10 This diagram illustrates the similarity determination of read / write permissions for common data points and machine data points according to one embodiment of the present invention. The second extraction unit 105 calculates a certain data point of the common data points (e.g., Figure 10 The similarity between the read / write permissions of data point 1) and the read / write permissions of each machine data point on the third machine (machine X) is calculated. Next, the second extraction unit 105 calculates the similarity between the read / write permissions of other data points of common data points (e.g., ...). Figure 10 The similarity between the read / write permissions of data point 2) and the read / write permissions of each machine data point of the third machine (machine X) is calculated. Similarly, the second extraction unit 105 performs similarity calculations on all data points of common data points.

[0183] Preferably, the control unit 1001 displays common data points on the user terminal 20 or the associated information generation device 10, and receives instructions from the user to confirm common data points. Thus, the user confirms the extracted common data points, and based on this, common data points can be determined.

This makes it easier to set up a new machine when adding it to the building management system.

[0188] Preferably, the control unit 1001 generates information that associates the common data points with the machine data points of the third machine based on the similarity between the names of the common data points and the names of the machine data points of the third machine.

Thus, the machine data points of the third machine can be associated with common data points that have similar descriptions of the definition.

[0190] Preferably, the control unit 1001 outputs common data points. This allows the acquisition of common data points associated with the machine data points of the third machine.

[0191] Preferably, the control unit 1001 generates information that associates the common data points with the machine data points of the third machine based on the similarity between the read / write permissions or units of the common data points and the read / write permissions or units of the machine data points of the third machine.

[0192] Preferably, the control unit 1001 can output information that associates common data points with machine data points of the third machine, or store it in a database. This allows other users to access the associated information.
