Description

[Technical Field]

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

[0002] Efforts are underway to provide new services that utilize building data collected by central building monitoring systems. Building central monitoring systems manage data using point names and point IDs. To search for the desired data, users must confirm the equipment location on the architectural drawings, confirm the equipment specifications on the equipment drawings, and then confirm the point that represents the desired data on the monitoring drawings. For example, if users want to utilize room temperature data, they must confirm the location of the air conditioning indoor unit on the architectural drawings, confirm the specifications for the temperature data that can be obtained from the air conditioning indoor unit on the equipment drawings, and then confirm the point that corresponds to that temperature data on the monitoring drawings. Because multiple drawings by different designers must be referenced in this way, utilizing data from the central monitoring system is time-consuming.

[0010] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 First, a plurality of models used in this embodiment will be described. FIG. 1 is a diagram showing the relationship between models according to an embodiment.

[0011] The standard model of the entire building system is a model that is predetermined as a standard and represents the types of building equipment that make up the building system and the connections between the equipment. The standard model of building equipment is a model that is predetermined as a standard and specifies the monitoring items and attributes of the building equipment.

[0012] For example, a standard model X for an entire building system represents the central monitoring device, air conditioning controller, air conditioning outdoor unit, air conditioning indoor unit, equipment controller, temperature sensor, and power receiving meter, as well as the connections between these pieces of equipment. There are multiple standard models for entire building systems, and the appropriate one for the target building is selected.

[0013] Standard models for building equipment include standard air conditioning controller models, air conditioning indoor unit models, air conditioning outdoor unit models, standard equipment controller models, standard temperature sensor models, and standard power receiving meter models.

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

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

[0016] Because building A only has a central monitoring device, equipment controller, and receiving power meter, a building system model for building A is created by deleting information related to the air conditioning controller, air conditioning outdoor unit, air conditioning indoor unit, and temperature sensor from standard model X of the entire building system. Furthermore, if the information on the central monitoring device, equipment controller, and receiving power meter included in standard model X of the entire building system does not include information on building A's central monitoring device, equipment controller, and receiving power meter, that information is supplemented using a standard model of the central monitoring device (not shown), an equipment controller standard model, and a receiving power meter standard model, and the building system model for building A is completed.

[0017] Because Building B only has a central monitoring device, an air conditioning controller, an air conditioning outdoor unit, an air conditioning indoor unit, an equipment controller, and a receiving power meter, a building system model for Building B is created by deleting information related to the temperature sensor from standard model X of the entire building system. Furthermore, if the information on the central monitoring device, air conditioning controller, air conditioning outdoor unit, air conditioning indoor unit, equipment controller, and receiving power meter included in standard model X of the entire building system does not include information on Building B's central monitoring device, air conditioning controller, air conditioning outdoor unit, air conditioning indoor unit, equipment controller, and receiving power meter, this information is supplemented using a standard model of the central monitoring device (not shown), a standard model of the air conditioning controller, a standard model of the air conditioning outdoor unit, a standard model of the air conditioning indoor unit, a standard model of the equipment controller, and a standard model of the receiving power meter, thereby completing the building system model for Building B. FIG. 2 is a diagram showing the configuration of a building management system 200 according to the first embodiment.

[0018] The building management system 200 includes 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 includes an input I / F unit 104 , an information conversion unit 105 , a model generation unit 106 , and a storage unit 107 .

[0020] An input I / F unit 104 receives input information 101 including physical configuration information 102 and logical configuration information 103 from the outside.

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

[0022] The storage unit 107 stores a building system model 108 and a standard model 109. The standard model includes a standard model of the entire building system and a standard model of 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 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 the building facilities, thereby executing processing for managing the building facilities. The input device 112 accepts input from the building manager (user). The display device 111 displays a management screen for building facilities and the like. FIG. 3 shows the configuration of the model generation unit 106.

[0024] 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 .

[0025] The entire building system standard model search unit 121 searches for the standard model of the entire building system stored in the memory unit 107 based on the target building information, and selects the standard model of the entire building system that is appropriate for the target building.

[0026] The entire building system standard model configuration deletion unit 123 deletes information about building equipment that is not included in the target building from the selected standard model of the entire building system.

[0027] If the selected standard model of the entire building system does not include information about the building equipment of the target building, the building equipment standard model search unit 124 searches for a standard model of the building equipment stored in the memory unit 107 that includes that information.

[0028] The building equipment standard model addition unit 125 creates a building system model of the target building by adding the retrieved standard model of the building equipment to the standard model of the entire building system, and stores the model in the storage unit 107. The building system model output unit 126 outputs the created building system model.

[0029] FIG. 4 is a flowchart showing the procedure for creating a building system model according to the first embodiment.

[0030] In step S101, the information conversion unit 105 receives input of the physical configuration information and logical configuration information of the target building.

[0031] Physical configuration information includes building shape information obtained from architectural drawings, building equipment installation location information, etc. Logical configuration information includes equipment subsystem design information and equipment setting information obtained from equipment drawings, as well as BAS (Building Automation System) network information, BAS management point information, interlocking control information, etc. obtained from BAS drawings.

[0032] 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 spatial configuration information of the building, communication configuration information of building facilities, and attribute information of the building facilities. The target building information may include at least the attribute information of the building facilities.

[0033] 5 is a diagram showing an example of space configuration information, which indicates the hierarchical relationships of spaces within a building.

[0034] FIG. 6 is a diagram showing an example of communication configuration information for building equipment in a target building. The communication configuration information for building equipment in a target building includes one or more elements. One element of the communication configuration information for the target building includes an element ID, equipment, a local address, and an IP address. For example, an element with element ID=1 includes an air conditioning indoor unit as equipment and 00-00-00-XX-XX-X3 as a local address, but does not include an IP address.

[0035] Figure 7 is a diagram showing an example of attribute information for building equipment in a target building. The attribute information for building equipment in a target building includes one or more elements. One element of the attribute information for the target building includes attributes for an element ID, equipment, model number, serial number, and Bluetooth (registered trademark) address. For example, the element with element ID = 1 includes an air conditioning indoor unit as equipment, PX-XXXXXXX1 as model number, 035-XXX-441 as serial number, and XX-XX-X1-00-00-00 as Bluetooth address.

[0036] In step S103, the entire building system standard model search unit 121 searches for an entire building system standard model stored in the storage unit 107 based on the target building information. The entire building system standard model search unit 121 searches for a standard model of the entire building system that has the highest proportion (match rate) of building equipment included in the target building information.

[0037] FIG. 8 is a visualized diagram of a standard model M1 of the entire building system. FIG. 9 is a visualized diagram of a standard model M2 of the entire building system. FIG. 10 is a diagram showing the standard models M1 and M2 of the entire building system. The standard model of the entire building system includes multiple elements. Each element represents building equipment and includes a model ID, an element ID, a name, a connection relationship, and a connection destination. When the connection relationship is hasPart, it indicates that the element is connected to and managed as the connection destination element represented by the element ID.

[0038] The entire building system standard model search unit 121 calculates the rate 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 match rate.

[0039] The standard model M1 of the entire building system includes the following building equipment: a central monitoring device, a lighting controller, lighting fixtures, an illuminance sensor, an equipment controller, a power receiving meter, and a temperature sensor. Of these seven pieces of building equipment, the proportion of those that are the same as the air conditioning indoor units, air conditioning outdoor units, and air conditioning controllers included in the target building information in Figures 6 and 7 is 0 / 7. Therefore, the matching rate of the standard model M1 of the entire building system is 0.

[0040] The standard model M2 of the entire building system includes the following building equipment: a central monitoring device, an air conditioning controller, an air conditioning outdoor unit, an air conditioning indoor unit, an equipment controller, a power receiving power meter, and a temperature sensor. Of these seven pieces of building equipment, 3 / 7 are the same as the air conditioning indoor unit, air conditioning outdoor unit, and air conditioning controller included in the target building information in Figures 6 and 7. Therefore, the matching rate of the standard model M2 of the entire building system is 3 / 7.

[0041] In step S104, the entire building system standard model search unit 121 selects the standard model of the entire building system with the highest matching rate from among the standard models of the entire building system stored in the storage unit 107. Therefore, the standard model M2 of the entire building system is selected.

[0042] In step S105, if the building equipment included in the selected standard model of the entire building system does not completely match the building equipment included in the target building information, the process proceeds to step S106. If they completely match, the selected standard model of the entire building system is stored in memory unit 107 as the building system model of the target building, and the process proceeds to step S112.

[0043] In step S106, if there is building equipment included in the selected overall building system standard model that is not included in the target building information, the process proceeds to step S107.

[0044] In step S107, the entire building system standard model configuration deletion unit 123 deletes information on building equipment included in the selected standard model of the entire building system that is not included in the target building information.

[0045] Figure 11 is a visualized diagram of the standard model M2 of the entire building system after deletion. Figure 12 is a diagram showing the standard model M2 of the entire building system after deletion. Information on the equipment controller, receiving power meter, and temperature sensor is deleted from the standard model M2 of the entire building system. As a result, the standard model M2 of the entire building system includes only information on the central monitoring device, air conditioning controller, air conditioning outdoor unit, and air conditioning indoor unit.

[0046] In step S108, if any information about the building equipment included in the target building information is not included in the selected standard model for the entire building system, processing proceeds to step S109. For example, standard model M2 for the entire building system in FIG. 12 includes an air conditioning indoor unit, but the information about 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, or Bluetooth address of the attribute information in FIG. 7. Therefore, processing proceeds to step S109. In reality, similar processing is also performed for the central monitoring device, air conditioning controller, and air conditioning outdoor unit of standard model M2 for the entire building system in FIG. 12, but only the example of the air conditioning indoor unit will be described below.

[0047] In step S109, the building equipment standard model search unit 124 searches for a standard model of building equipment based on the target building information. The building equipment standard model search unit 124 calculates the rate of matching as the proportion of elements included in the standard model of building equipment that are the same as the attributes of building equipment included in the attribute information of building equipment in the target building information.

[0048] Fig. 13 is a visualized diagram of standard model CM1 of an air conditioning indoor unit. Fig. 14 is a visualized diagram of standard model CM2 of an air conditioning indoor unit. Fig. 15 is a diagram showing standard models CM1 and CM2 of air conditioning indoor units.

[0049] The standard model of building equipment includes multiple 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. If the connection relationship 1 is hasPoint, it indicates that the element of connection destination 1 represented by the element ID is used as a monitoring point. If the connection relationship 2 is hasTag, it indicates that the element of connection destination 2 represented by the element ID is used as attribute information.

[0050] The standard building equipment model CM1 includes seven elements. The elements are the 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, 2 / 7 have the same names as the model number, serial number, and Bluetooth address of the air conditioning indoor unit, which are attributes included in the attribute information of the building equipment of the target building in Figure 7. Therefore, the matching rate of the standard building equipment model CM1 is 2 / 7.

[0051] The standard model CM2 of building equipment contains seven elements. The elements are the air conditioning indoor unit (BLE sensor), power ON / OFF, intake temperature, M-NET address, model number, serial number, and Bluetooth address. Of these seven pieces of attribute information, 3 / 7 have the same names as the model number, serial number, and Bluetooth address of the air conditioning indoor unit, which are attributes included in the building attribute information of the target building in Figure 7. Therefore, the matching rate of the standard model CM2 of building equipment is 3 / 7.

[0052] In step S110, the building equipment standard model search unit 124 selects the building equipment standard model with the highest matching rate from among the building equipment standard models stored in the storage unit 107. Therefore, the building equipment standard model CM2 is selected.

[0053] In step S111 , the building equipment standard model addition unit 125 creates a building system model by adding the standard model of the selected building equipment to the overall model of the building system, and stores the model in the storage unit 107 .

[0054] Fig. 16 is a visualized diagram of the building system model. Fig. 17 is a diagram showing a standard model of the entire building system included in the building system model. Fig. 18 is a diagram showing a standard model of building equipment included in the building system model.

[0055] In step S112, the building system model output unit 126 stores the created building system model in the storage unit 107 and outputs it to the model utilization unit 110 as necessary. Data related to the properties of the created building system model may be incorporated. For example, in a model of an air conditioning indoor unit, the model number, serial number, and Bluetooth address of the actual unit may be stored in the model number, serial number, and Bluetooth address properties. Alternatively, a data identification ID of a database in which data about the actual unit is stored may be stored in these properties.

[0056] For example, the model utilization unit 110 can use the building system model of the target building stored in the memory unit 107, and the actual equipment data written in those properties or the database identification ID in which the actual equipment data is stored, to obtain data such as the intake temperature of an air conditioning indoor unit without referring to an equipment drawing, and use the data to manage the building equipment.

[0057] According to this embodiment, the data model is automatically generated, which reduces the time and effort required to create a data model that represents building equipment information. It also eliminates the need to refer to equipment drawings to search for data. This makes it possible to streamline the work required to utilize building data. Embodiment 2 FIG. 19 is a diagram illustrating the configuration of a building management system 200A according to the second embodiment.

[0058] A building management system 200A according to the second embodiment includes a building system model creation device 100A instead of the building system model creation device 100 according to the first embodiment.

[0059] The building system model creation device 100A of the second embodiment includes a model generation unit 106A in addition to the model generation unit 106. The storage unit 107 of the second embodiment stores a building system model 108A instead of the building system model 108, and stores a data store 301. FIG. 20 illustrates a configuration of model generation unit 106A according to the second embodiment.

[0060] The model generation unit 106A of the second embodiment differs from the model generation unit 106 of the first embodiment in that the model generation unit 106A of the second embodiment includes a data store association unit 303.

[0061] FIG. 21 is a flowchart showing the procedure for creating a building system model according to the second embodiment. In step S200, the processes of steps S101 to S112 are executed.

[0062] In step S201, if the association of all building system models and data locations for the target building has not been completed, the process proceeds to step S202, and if all associations have been completed, the process proceeds to step S203.

[0063] In step S202, the data store association unit 303 associates the building equipment of the building system model of the target building with the related data and the location of the data, based on the data store 301. The data store 301 is defined by data information and data storage information.

[0064] Figure 22 is a diagram showing data information. The data information includes information defining multiple pieces of data. The information defining each piece of data includes a data ID, a data name, and the ID of the data storage location where the data is stored. For example, data with a data ID of D00001 has a data name of "power on / off" and a data storage location ID of DS1.

[0065] Figure 23 is a diagram showing data storage information. The data storage information includes information defining multiple data storage locations. The information defining 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.

[0066] The data stored in the data storage location is variable data and can be changed by the user or automatically. For example, the M-NET address can be rewritten by the user. The intake temperature is successively rewritten based on the data detected by the temperature sensor.

[0067] Figure 24 is a diagram showing 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 standard model CM2 of an air conditioning indoor unit matches the data name of data ID = D0001 in the data information in Figure 22, so data ID = D00001 is added to the element with element ID = 009. By referencing 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 in data storage location DS1.

[0068] The name of the element with element ID = 010 (suction temperature) for the air conditioning indoor unit standard model CM2 matches the data name of data ID = D0002 in the data information in Fig. 22, so data ID = D00002 is added to the element with element ID = 010. By referring to the data information in Fig. 22 and the data storage location information in Fig. 23, it can be seen that the storage location of data ID = D0002 is address 192.XXX.XXX.XX1 of data storage location DS1.

[0069] 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 in Fig. 22, so data ID=D0003 is added to the element with element ID=011. By referring to the data information in Fig. 22 and the data storage location information in Fig. 23, it can be seen that the storage location of data ID=D0003 is address 192.XXX.XXX.XX2 of data storage location DS2.

[0070] The name (model number) of the element with element ID = 012 for the standard model CM2 air conditioning indoor unit matches the data name of data ID = D0004 in the data information in Fig. 22, so data ID = D0004 is added to the element with element ID = 012. By referring to the data information in Fig. 22 and the data storage location information in Fig. 23, it can be seen that the storage location of data ID = D0004 is address 192.XXX.XXX.XX2 in data storage location DS2.

[0071] The name (serial number) of the element with element ID = 013 of the air conditioning indoor unit standard model CM2 matches the data name of data ID = D0005 in the data information in Fig. 22, so data ID = D0005 is added to the element with element ID = 013. By referring to the data information in Fig. 22 and the data storage location information in Fig. 23, it can be seen that the storage location of data ID = D0005 is address 192.XXX.XXX.XX2 of data storage location DS2.

[0072] The name (Bluetooth address) of the element with element ID = 014 of the air conditioning indoor unit standard model CM2 matches the data name of data ID = D0006 in the data information in Fig. 22, so data ID = D0006 is added to the element with element ID = 014. By referring to the data information in Fig. 22 and the data storage location information in Fig. 23, it can be seen that the storage location of data ID = D0006 is address 192.XXX.XXX.XX2 of data storage location DS2.

[0073] The building system model output unit 126A of the model generation unit 106A stores in the memory unit 107A a building system model including a standard model of building equipment in which building equipment of the building system of the target building is associated with related data and the location of the data. The building system model including the standard model CM2 of building equipment in Figure 24 is stored in the memory unit 107A. The building system model output unit 126A stores the input data store 301 in the memory unit 107A.

[0074] In step S203, the building system model output unit 126 outputs the building system model stored in the storage unit 107A as necessary.

[0075] Model utilization unit 110A executes processing for building management using building system model 108A stored in storage unit 107A and data store 301. For example, a building system model including standard model M2 of the entire building system in Fig. 17 and standard model CM2 of the air conditioning indoor unit in Fig. 24, and the data stores in Fig. 22 and Fig. 23 are used. For example, when using the intake temperature of the air conditioning indoor unit, model utilization unit 110A references the data store and accesses address 192.XXX.XXX.X1 of data storage location DS1.

[0076] The building management systems described in the first and second embodiments above can be configured with corresponding operations implemented by digital circuit hardware or software. When the building management system is implemented using software, the building management system includes, for example, a processor 501, a memory 502, a display device 111, an input device 112, and a communication device 506, which are connected by a bus 900, as shown in Fig. 25.
