Description

Building System Model Creation Device, Building Management System, and Building System Model Creation Method

[0001] The present disclosure relates to a building system model creation device, a building management system, and a building system model creation method.

[0002] Efforts are underway to provide new services by utilizing building data collected by a building's central monitoring system. The building's central monitoring system manages data by point name and point ID. To search for target data, it is necessary to check the equipment location in the architectural drawing, check the equipment specifications in the equipment drawing, and check the point representing the target data in the monitoring drawing. For example, when wanting to utilize room temperature data, check the location of the air conditioner indoor unit in the architectural drawing, check the specifications of the temperature data that can be obtained from the air conditioner indoor unit in the equipment drawing, and check the point corresponding to that temperature data in the monitoring drawing. Thus, because multiple drawings by different designers are referred to, it takes time to utilize the data of the central monitoring system.

[0003] Patent Document 1 describes a technique of referring to a building construction standard database regarding a building, obtaining appearance data of a building to be managed, creating appearance basic data, and editing to create data.

The standard model for the entire building system defines multiple pieces of equipment installed in the building and the connection relationships between the multiple pieces of equipment, while the standard model for building equipment defines the monitoring items and attributes of the building equipment. The building system model creation device further includes a model generation unit that generates a building system model for a target building using the standard model for the entire building system and the standard model for building equipment, based on information about the building equipment of the target building.

[0010] The embodiments will be described below with reference to the drawings. Embodiment 1. First, the multiple models used in this embodiment will be described.

[0011] Figure 1 is a diagram illustrating the relationships between models according to the embodiment. The standard model for the entire building system is a predetermined standard model that represents the types of building equipment constituting the building system and the connection relationships between the building equipment. The standard model for building equipment is a predetermined standard model that defines the monitoring items and attributes of the building equipment.

[0012] For example, a standard model X for an entire building system represents a central monitoring unit, an HVAC controller, outdoor HVAC units, indoor HVAC units, equipment controllers, temperature sensors, and power meters, along with the connections between these components. Multiple standard models for entire building systems are available, and the appropriate one is selected for the building in question.

[0013] Standard models for building equipment include standard air conditioning controllers, indoor air conditioning units, outdoor air conditioning units, equipment controllers, temperature sensors, and power meters.

[0014] The building system model creation device of this embodiment creates building system models for each building, such as Building A and Building B, using these two standard models. This reduces the effort required to refer to multiple drawings, making it possible to monitor and manage building facilities.

[0015] The building system models for Building A and Building B utilize the aforementioned standard model X for the entire building system. Unnecessary parts are removed from this standard model X for the entire building system, and missing parts are supplemented from the standard model of the building equipment.

[0016] Since Building A only has a central monitoring system, equipment controllers, and power meters, the building system model for Building A is created by removing information related to the air conditioning controllers, outdoor units, indoor units, and temperature sensors from the standard building system model X. Furthermore, if there is any information in the standard building system model X that does not include information for Building A's central monitoring system, equipment controllers, and power meters, that information is supplemented using the standard model of the central monitoring system (not shown), the standard model of the equipment controller, and the standard model of the power meter, thereby completing the building system model for Building A.

[0017] Since Building B only has a central monitoring system, an air conditioning controller, an outdoor air conditioning unit, an indoor air conditioning unit, an equipment controller, and a power receiving meter, the building system model for Building B is created by removing the information related to temperature sensors from the standard model X of the entire building system. Furthermore, if there is information in the standard model X of the entire building system that does not include information for the central monitoring system, air conditioning controller, outdoor air conditioning unit, indoor air conditioning unit, equipment controller, and power receiving meter of Building B, then the building system model for Building B is completed by supplementing that information using the standard model of the central monitoring system (not shown), the standard model of the air conditioning controller, the standard model of the outdoor air conditioning unit, the standard model of the indoor air conditioning unit, the standard model of the equipment controller, and the standard model of the power receiving meter.

[0018] Figure 2 is a diagram showing the configuration of the building management system 200 according to Embodiment 1. The building management system 200 comprises a building system model creation device 100, a model utilization unit 110, an input device 112, and a display device 111.

[0019] The building system model creation device 100 comprises an input I / F unit 104, an information conversion unit 105, a model generation unit 106, and a storage unit 107.

[0020] The input I / F unit 104 receives input information 101, which includes physical configuration information 102 and logical configuration information 103, from an external source.

[0021] The information conversion unit 105 converts the physical configuration information 102 and logical configuration information 103 into spatial configuration information, communication configuration information, and attribute information.

[0022] The memory unit 107 stores the building system model 108 and the standard model 109. The standard model includes a standard model of the entire building system and a standard model of the building equipment. The building system model 108 is generated by the model generation unit 106. The standard model of the entire building system and the standard model of the building equipment are created in advance.

[0023] The model utilization unit 110 uses the building system model stored in the storage unit 107 to acquire data necessary for managing building facilities, thereby executing processes for managing building facilities.

[0024] The input device 112 accepts input from the building manager (user). The display device 111 displays the building equipment management screen, etc.

[0025] Figure 3 shows the configuration of the model generation unit 106. The model generation unit 106 includes a building system overall standard model search unit 121, a building system overall standard model configuration deletion unit 123, a building equipment standard model search unit 124, a building equipment standard model addition unit 125, and a building system model output unit 126.

[0026] The building system overall standard model search unit 121 searches for the building system overall standard model stored in the storage unit 107 based on the target building information and selects the building system overall standard model appropriate for the target building.

[0027] The building system overall standard model configuration deletion unit 123 deletes information about building equipment that is not included in the target building from the selected building system overall standard model.

[0028] The building equipment standard model search unit 124 searches for the building equipment standard model stored in the storage unit 107, which contains such information, if the selected standard model for the entire building system does not include information about the building equipment of the target building.

[0029] The building equipment standard model addition unit 125 creates a building system model for the target building by adding the retrieved standard model of the building equipment to the standard model of the entire building system, and stores it in the storage unit 107.

[0030] The building system model output unit 126 outputs the created building system model. Figure 4 is a flowchart showing the procedure for creating the building system model in Embodiment 1.

[0031] In step S101, the information conversion unit 105 receives the physical configuration information and logical configuration information of the target building.

[0032] Physical configuration information includes building shape information and building equipment installation location information obtained from architectural drawings. Logical configuration information includes equipment subsystem design information and equipment setting information obtained from equipment drawings, and BAS (Building Automation System) network information, BAS control point information, and interlocking control information obtained from BAS (Building Automation System) drawings.

[0033] In step S102, the information conversion unit 105 creates target building information from the physical configuration information and logical configuration information of the target building. The target building information includes the spatial configuration information of the building, the communication configuration information of the building equipment, and the attribute information of the building equipment. The target building information may include at least the attribute information of the building equipment.

[0034] Figure 5 is a diagram illustrating an example of spatial configuration information. Spatial configuration information represents the hierarchical relationships of spaces within a building.

[0035] Figure 6 shows an example of communication configuration information for the building equipment of a target building. The communication configuration information for the building equipment of a target building includes one or more elements. One element of the communication configuration information for the target building includes the configuration of element ID, equipment, local address, and IP address. For example, the element with element ID = 1 includes an air conditioning indoor unit as equipment, 00-00-00-XX-XX-X3 as the local address, and does not include an IP address.

[0036] Figure 7 shows an example of attribute information for the building equipment of a target building. The attribute information for the building equipment of a target building includes one or more elements. One element of the attribute information for the target building includes the attributes of element ID, equipment, model number, serial number, and Bluetooth® address. For example, the element with element ID = 1 includes an air conditioning indoor unit as the equipment, PX-XXXXXXXXX1 as the model number, 035-XXX-441 as the serial number, and XX-XX-X1-00-00-00 as the Bluetooth address.

[0037] In step S103, the building system overall standard model search unit 121 searches for the building system overall standard model stored in the storage unit 107 based on the target building information. The building system overall standard model search unit 121 searches for the building system overall standard model with the highest percentage (match rate) of building equipment included in the target building information.

[0038] Figure 8 is a visualization of the standard model M1 for the entire building system. Figure 9 is a visualization of the standard model M2 for the entire building system. Figure 10 is a diagram showing the standard models M1 and M2 for the entire building system. The standard model for the entire building system includes multiple elements. Each element represents a building facility and includes a model ID, element ID, name, connection relationship, and connection destination. When the connection relationship is hasPart, it indicates that it is connected to and managed by the element at the connection destination represented by the element ID.

[0039] The building system overall standard model search unit 121 calculates the percentage of building equipment included in the standard model of the entire building system that is the same as the building equipment included in the target building information as the matching rate.

[0040] The standard model M1 for the entire building system includes, as building equipment, a central monitoring system, a lighting controller, lighting fixtures, an illuminance sensor, an equipment controller, a power receiving meter, and a temperature sensor. Of these seven building equipment components, the proportion of the same building equipment as the indoor air conditioning unit, outdoor air conditioning unit, and air conditioning controller included in the target building information in Figures 6 and 7 is 0 / 7. Therefore, the matching rate of the standard model M1 for the entire building system is 0.

[0041] The standard model M2 for the entire building system includes, as building equipment, a central monitoring device, an air conditioning controller, an outdoor air conditioning unit, an indoor air conditioning unit, an equipment controller, a power receiving meter, and a temperature sensor. Of these seven building equipment components, the proportion of the indoor air conditioning unit, outdoor air conditioning unit, and air conditioning controller included in the target building information in Figures 6 and 7 is 3 / 7. Therefore, the matching rate of the standard model M2 for the entire building system is 3 / 7.

[0042] In step S104, the overall building system standard model search unit 121 selects the standard model of the overall building system stored in the storage unit 107 with the highest matching rate. Therefore, the standard model M2 of the overall building system is selected.

[0043] In step S105, if the building facilities included in the selected standard model of the overall building system do not exactly match the building facilities included in the target building information, the process proceeds to step S106. If they exactly match, the selected standard model of the overall building system is stored in the storage unit 107 as the building system model of the target building, and the process proceeds to step S112.

[0044] In step S106, if there are building facilities included in the selected standard model of the overall building system that are not included in the target building information, the process proceeds to step S107.

[0045] In step S107, the overall building system standard model configuration deletion unit 123 deletes the information of the building facilities included in the selected standard model of the overall building system that are not included in the target building information.

[0046] FIG. 11 is a diagram visualizing the standard model M2 of the overall building system after deletion. FIG. 12 is a diagram representing the deleted standard model M2 of the overall building system. Information on the equipment controller, power reception meter, and temperature sensor is deleted from the standard model M2 of the overall building system. As a result, the standard model M2 of the overall building system includes only information on the central monitoring device, air conditioning controller, outdoor air conditioner, and indoor air conditioner.

[0047] In step S108, if there is information among the building facility information included in the target building information that is not included in the standard model of the entire selected building system, the process proceeds to step S109. For example, the standard model M2 of the entire building system in FIG. 12 includes an air-conditioning indoor unit, but the information of the air-conditioning indoor unit only includes a connection relationship (NULL) and a connection destination (NULL), and does not include the model number, serial number, and Bluetooth address of the attribute information in FIG. 7. Therefore, the process proceeds to step 109. The same process is actually executed for the central monitoring device, air-conditioning controller, and air-conditioning outdoor unit of the standard model M2 of the entire building system in FIG. 12, but only the example of the air-conditioning indoor unit will be described below.

[0048] In step S109, the building facility standard model search unit 124 searches for the standard model of the building facility based on the target building information. The building facility standard model search unit 124 calculates the ratio of the same elements as the attributes of the building facility included in the attribute information of the building facility in the target building information among the elements included in the standard model of the building facility as the matching rate.

[0049] FIG. 13 is a diagram visualizing the standard model CM1 of the air-conditioning indoor unit. FIG. 14 is a diagram visualizing the standard model CM2 of the air-conditioning indoor unit. FIG. 15 is a diagram showing the standard models CM1 and CM2 of the air-conditioning indoor unit.

[0050] The standard model of the building facility includes a plurality of elements. Each element includes a model ID, an element ID, a name, a connection relationship 1, a connection destination 1, a connection relationship 2, and a connection destination 2. When the connection relationship 1 is hasPoint, it represents that the element of the connection destination 1 represented by the element ID is used as a monitoring point. When the connection relationship 2 is hasTag, it represents that the element of the connection destination 2 represented by the element ID is used as attribute information.

[0051] The standard building equipment model CM1 includes seven elements. Each element is an air conditioning indoor unit (with Move Eye), power ON / OFF, intake temperature, number of people, M-NET address (a type of local address), model number, and serial number. Of these seven elements, the proportion of those with the same names as the air conditioning indoor unit model number, serial number, and Bluetooth address, which are attributes included in the building equipment attribute information of the target building in Figure 7, is 2 / 7. Therefore, the matching rate of the standard building equipment model CM1 is 2 / 7.

[0052] The standard model CM2 for building equipment includes seven elements. Each element is an air conditioning indoor unit (BLE sensor), power ON / OFF status, intake temperature, M-NET address, model number, serial number, and Bluetooth address. Of these seven attribute pieces of information, the proportion of those with the same names as the air conditioning indoor unit's model number, serial number, and Bluetooth address, which are included in the building attribute information of the target building in Figure 7, is 3 / 7. Therefore, the matching rate of the standard model CM2 for building equipment is 3 / 7.

[0053] In step S110, the building equipment standard model search unit 124 selects the one with the highest matching rate from among the standard building equipment models stored in the storage unit 107. Therefore, the standard building equipment model CM2 is selected.

[0054] In step S111, the building equipment standard model addition unit 125 creates a building system model by adding the selected standard model of building equipment to the overall building system model and stores it in the storage unit 107.

[0055] Figure 16 is a visualization of the building system model. Figure 17 is a diagram representing the standard model of the entire building system included in the building system model. Figure 18 is a diagram representing the standard model of building equipment included in the building system model.

[0056] In step S112, the building system model output unit 126 stores the created building system model in the storage unit 107 and, if necessary, outputs it to the model utilization unit 110. Data related to the properties of the created building system model may be incorporated. For example, the model of an air conditioning indoor unit can store the model number, serial number, and Bluetooth address of the actual unit in its properties. Alternatively, the data identification ID of the database where the data of the actual unit is stored may be stored in these properties.

[0057] For example, the model utilization unit 110 can use the building system model of the target building stored in the storage unit 107, and the actual equipment data written to their properties, or the database identification ID in which the actual equipment data is stored, to acquire data such as the intake temperature of the indoor unit of the air conditioning system without referring to equipment drawings, and use it for the management of the building equipment.

[0058] According to this embodiment, by automatically generating a data model, the effort required to create a data model that represents information about building facilities can be reduced. Furthermore, it becomes unnecessary to refer to facility drawings to find data. Therefore, the process of utilizing building data can be streamlined.

[0059] Embodiment 2. Figure 19 is a diagram showing the configuration of the building management system 200A according to Embodiment 2.

[0060] The building management system 200A of Embodiment 2 includes a building system model creation device 100A instead of the building system model creation device 100 of Embodiment 1.

[0061] The building system model creation device 100A of Embodiment 2 includes a model generation unit 106A in addition to the model generation unit 106. The storage unit 107 of Embodiment 2 stores the building system model 108A instead of the building system model 108 and stores the data store 301.

[0062] Figure 20 shows the configuration of the model generation unit 106A of Embodiment 2. The difference between the model generation unit 106A of Embodiment 2 and the model generation unit 106 of Embodiment 1 is that the model generation unit 106A of Embodiment 2 includes a data store mapping unit 303.

[0063] Figure 21 is a flowchart illustrating the procedure for creating the building system model of Embodiment 2.

[0064] In step S200, the processes in steps S101 to S112 are executed. In step S201, if the mapping between the building system model and data location of the target building has not been completed, the process proceeds to step S202; otherwise, the process proceeds to step S203.

[0065] In step S202, the data store mapping unit 303 maps the building equipment of the target building's building system model to the associated data and the location of the data based on the data store 301.

[0066] The data store 301 is defined by data information and data storage information. Figure 22 is a diagram representing the data information. The data information includes information that defines multiple data. The information that defines each data includes a data ID, a data name, and the ID of the data storage location where it is stored. For example, the data with data ID D00001 has a data name of power ON / OFF and a data storage location ID of DS1.

[0067] Figure 23 is a diagram representing data storage information. The data storage information includes information that defines multiple data storage locations. The information that defines each data storage location includes a data storage location ID, a data storage location name, and a data storage location address. For example, the data storage location with ID DS1 has a data storage location name of BACnet data storage and a data storage location address of 192.XXX.XXX.XX1.

[0068] The data stored in the data storage location is variable data that can be modified by the user or changes automatically. For example, the M-NET address can be rewritten by the user. The intake temperature is continuously updated by data detected by the temperature sensor.

[0069] Figure 24 shows a standard model of building equipment included in a building system model associated with a data store. The element name of element ID = 009 (Power ON / OFF) of the standard model CM2 of the air conditioning indoor unit matches the data name of data ID = D0001 in the data information of Figure 22, so data ID = D00001 is added to the element of element ID = 009. By referring to the data information in Figure 22 and the data storage location information in Figure 23, it can be seen that the storage location of data ID = D0001 is address 192.XXX.XXX.XX1 of data storage location DS1.

[0070] The name of element ID = 010 (suction temperature) of the standard model CM2 air conditioning indoor unit matches the data name of data ID = D0002 in the data information of Figure 22. Therefore, data ID = D00002 is added to the element of element ID = 010. By referring to the data information of Figure 22 and the data storage location information of Figure 23, it can be seen that the storage location of data ID = D0002 is address 192.XXX.XXX.XX1 of data storage location DS1.

[0071] The element name (M-NET address) of element ID = 011 of the standard model CM2 air conditioning indoor unit matches the data name of data ID = D0003 in the data information of Figure 22. Therefore, data ID = D0003 is added to the element of element ID = 011. By referring to the data information of Figure 22 and the data storage location information of Figure 23, it can be seen that the storage location of data ID = D0003 is the address 192.XXX.XXX.XX2 of data storage location DS2.

[0072] The element name (model number) of element ID = 012 of the standard model CM2 air conditioning indoor unit matches the data name of data ID = D0004 in the data information of Figure 22. Therefore, data ID = D0004 is added to the element of element ID = 012. By referring to the data information of Figure 22 and the data storage location information of Figure 23, it can be seen that the storage location of data ID = D0004 is address 192.XXX.XXX.XX2 of data storage location DS2.

[0073] The element name (serial number) of element ID = 013 in the standard model CM2 of the air conditioning indoor unit matches the data name of data ID = D0005 in the data information in Figure 22. Therefore, data ID = D0005 is added to the element of element ID = 013. By referring to the data information in Figure 22 and the data storage location information in Figure 23, it can be seen that the storage location of data ID = D0005 is address 192.XXX.XXX.XX2 in data storage location DS2.

[0074] The element name (Bluetooth address) of element ID = 014 in the standard model CM2 of the air conditioning indoor unit matches the data name of data ID = D0006 in the data information in Figure 22. Therefore, data ID = D0006 is added to the element of element ID = 014. By referring to the data information in Figure 22 and the data storage location information in Figure 23, it can be seen that the storage location of data ID = D0006 is address 192.XXX.XXX.XX2 in the data storage location DS2.

[0075] The building system model output unit 126A of the model generation unit 106A stores a building system model in the storage unit 107A, which includes a standard model of the building equipment associated with the building equipment of the target building's building system, and the location of that data. The building system model including the standard model CM2 of the building equipment shown in Figure 24 is stored in the storage unit 107A. The building system model output unit 126 stores the input data store 301 in the storage unit 107A.

[0076] In step S203, the building system model output unit 126 outputs the building system model stored in the storage unit 107A as needed.

[0077] The model utilization unit 110A uses the building system model 108A stored in the storage unit 107A and the data store 301 to perform building management processing. For example, a building system model including the standard model M2 of the entire building system shown in Figure 17 and the standard model CM2 of the indoor air conditioning unit shown in Figure 24, and the data stores shown in Figures 22 and 23 are used. For example, when the model utilization unit 110A uses the intake temperature of the indoor air conditioning unit, it refers to the data store and accesses the address 192.XXX.XXX.X1 of the data storage location DS1.

[0078] The building management systems described in Embodiments 1 and 2 above can be configured using digital circuit hardware or software for the corresponding operations. When the building management system is implemented using software, the building management system includes, for example, a processor 501 connected by a bus 900, a memory 502, a display device 111, an input device 112, and a communication device 506, as shown in Figure 25. The processor 501 can be configured to execute a program stored in the memory 502.

[0079] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the invention is indicated by the claims rather than the foregoing description, and all modifications within the meaning and scope of equivalents of the claims are intended.
