[0002] With the development of building information modeling (BIM) technology and the government's vigorous promotion, the trend of combining BIM with building operation and maintenance management is becoming more and more obvious, bringing new technical support for building operation and maintenance management. On the basis of viewing two-dimensional drawings, operation and maintenance personnel can understand the structure of the building system and locate the position of each system component by observing the three-dimensional BIM building model.

[0003] However, it is still very troublesome for operation and maintenance personnel to manage the building system through BIM models. For example, operators still need to observe the building model through two-dimensional screen devices. At the same time, operation and maintenance personnel can only call the static structural data of the building system through the BIM model, which makes the management of the building system inefficient.

[0046] See also Figure 1 , Figure 1 is a schematic diagram of a building management system provided in an embodiment of the present application. It should be noted that: Figure 1 The building management system shown is only an example, and the management system protected by this application does not necessarily include Figure 1 All modules or components shown may also include only Figure 1 Some modules or components shown in (for example, in one implementation, the building management system may only include: MR device 111, BMS 121, relay server 131), and may also include Figure 1 This application does not limit other necessary modules or components.

[0047] like Figure 1As shown, the building management system includes a mixed reality application layer 110, wherein the mixed reality layer 110 includes a mixed reality MR device 111. MR device is a wearable device (such as wearable glasses) that applies mixed reality technology, and MR technology is a technology that integrates the physical world with the digital world. The development of MR technology has solved many problems encountered by the industry. The MR device in this application may include modules such as a processor, a memory, a display unit, and an input unit, which are not limited in this application. It should be understood that this application does not limit the specific type and model of the MR device. In some scenarios, the MR device here can also be replaced by an augmented reality (AR) device or a virtual reality (VR) device, or other devices that can achieve the integration of the physical world and the digital world. MR devices can not only allow users to see virtual objects in the real world, but also allow users to manipulate virtual objects. Applying MR devices to the building management system allows users to observe the structure of building equipment more clearly, and conveniently allow users to manipulate the operating data of the building system. For specific solutions, please refer to the description in the subsequent method 200.

[0048] The management system further includes a local device layer 120, wherein the local device layer 120 includes a building equipment management system BMS121, and BMS121 is a system for implementing comprehensive management of building equipment monitoring systems and public safety systems.

[0049] The management system also includes a cloud server layer 130, wherein the cloud server layer 130 includes a relay server 131, which can also be called a remote control server. The relay server 131 is, for example, powered by the message queuing telemetry transport protocol (MQTT). The MR device 111 is connected to the BMS 121 via the relay server 131, that is, the MR device 111 can communicate bidirectionally with the BMS 121 via the relay server 131. Through this function, users (such as operation and maintenance personnel or users) can directly modify the operating data of the building system (specified equipment within) through the control function of the MR device 111. For specific solutions, please refer to Figure 2 The method 200 shown:

[0050] S210 , the MR device reads the data of the building system from the database and displays the data in a mixed reality environment.

[0051] Exemplarily, the MR device can read and display data of the building system, which includes static data and / or operation data of the building system. A possible implementation is described below in an exemplary manner.

[0052] Optionally, before the MR device reads and displays the data of the building system, the MR device loads the model of the building system based on the model data of the building system. It should be noted that the building system here refers to the building system to be managed in the embodiment of the present application, and the building system is only a general term, which can represent one or more rooms, a building, or a building complex. Its meaning depends on the specific application scenario and is not limited in the present application.

[0053] The model of the building system is a digital model that is completely consistent with the size of the building system in the real world. For example, the BIM model of the building system is first obtained, then exported as a model in NWC format, and then the texture and details of the model are adjusted, and then the model in NWC format is exported to FBX format, and the model in FBX format is imported into the MR device 111. In this way, the texture material and other characteristics of the model can be retained, the richness of the model data is improved, and the problem of texture material loss caused by directly exporting the BIM model to the FBX format model is avoided.

[0054] Further, the generated digital model is corresponded to the building system in the real world, and the correspondence here refers to completely overlapping the digital model with the building system in the real world. As an example, the three-dimensional grid information of the building system is first obtained. The MR device can directly obtain the three-dimensional grid information by scanning the building environment, or it can obtain the three-dimensional grid information from the storage. For example, if it is the first time to come to the current building system, the building environment can be scanned by the depth camera of the MR device to generate the three-dimensional grid information of the building system. After the three-dimensional grid information of the building system is generated for the first time, the MR device can store the three-dimensional grid information. If it is not the first time to come to the building system, the three-dimensional grid information can be read directly from the storage. The environmental grid scanning result can directly reflect the spatial relationship between the MR device and the surrounding geometry (i.e., the device or device in the building system), so as to judge the user's position in the real world, and assist the spatial anchor program to determine the digital model to achieve model positioning in the real world. In some scenarios, such as when you first start the platform, you need to manually adjust the model position until the model completely overlaps with the actual building system. Then, after saving the position through the spatial anchor point, you only need to start the program near the saved position of the spatial anchor point, and the digital model will automatically complete the positioning, thereby increasing work efficiency and improving user experience. Through the above solution, the digital model of the building system can be visualized in a mixed reality environment through MR devices. After completing the spatial positioning of the model, the user can clearly see the building system model in the real building, and the size and position of the model are exactly the same as the actual one. At the same time, users can also use this function to see building structures or devices that are out of sight or blocked from view. Please refer to Figure 3 , Figure 3 This is an application case provided by the embodiment of the present application in a practical environment, such as Figure 3 As shown in the figure, users can observe the air conditioning system hidden in the ceiling of the office through MR equipment. Through this function, it can easily help users (such as operation and maintenance personnel) understand the composition of various functional systems (such as electromechanical systems) in the building system, and at the same time, they can see electromechanical pipelines and equipment that cannot be directly seen by the naked eye, assisting operation and maintenance work and improving work efficiency.

[0055] Compared with the traditional two-dimensional drawings or two-dimensional interface display methods, the present application runs the digital model of the building system in the MR device, which is more convenient and has strong visibility than the existing technology. For example, for the three-dimensional model directly generated by BIM technology, most engineers and building operation and maintenance personnel can only browse with the help of two-dimensional screen devices such as smart phones and smart tablets, which cannot provide real spatial perception and good interactive experience. By directly loading the digital model of the building system through the MR device, the structure of the building system can be displayed to the user more conveniently and intuitively. In addition, the spatial positioning of the digital model mostly uses QR code scanning or mobile hotspots (wireless fidelity, WIFI), radio frequency identification (radiofrequency identification, RFID) signal perception methods. The former requires posting QR codes in the building to affect the beauty of the building, and the latter has low positioning accuracy and the indoor WIFI signal is relatively unstable. In the solution of the present application, the three-dimensional model of the building system can be displayed quickly and stably without relying on network signals.

[0056] On the other hand, users can directly interact with the model of the building system through the interactive functions in the MR device, or control some functions of the building system management system. For example, users can interact with the model based on the "eye tracking" and "gesture recognition" functions of the MR device, or send instructions to the BMS121. Users only need to "gaze" and make simple gestures to complete all tasks in the platform. Specific user interaction operation methods include but are not limited to the following:

[0057] 1. Eye tracking: Users can set "eye tracking" as the default object selection method. When users need to interact with an object (such as viewing the information of a device in the building system, moving a window, closing a window, etc.), they only need to look at the target object;

[0058] 2. Right-hand click: Within the field of vision, use the right index finger and thumb to complete the "pinch" action to activate the function of the currently selected target;

[0059] 3. Touch: You can use your hands to touch interactive device objects, such as buttons, and activate their functions.

[0060] Of course, in addition to the interaction methods introduced above, users can also interact with the platform in other ways, such as through physical buttons, voice input, text input, etc., which is not limited in this application.

[0061] Optionally, in a possible implementation, the MR device can display the user's current location or the location where an alarm occurs in the building system based on the user's instructions. Figure 4 , assuming Figure 4 It is a partial floor plan of the building system. Based on the user's instructions, the MR device can display the user's current location and the location of the alarm in the building system. The MR device can directly display the user's Figure 4 Floor plan shown.

[0062] Optionally, in a possible implementation, the MR device can display a navigation route map with the destination being a certain device or apparatus in the building system (such as an air handling unit (AHU) or a variable air volume (VAV) air conditioning system terminal device) based on the user's instructions. Figure 5 :Assuming the user selects the VAV in the building system as the destination, the MR device will automatically generate navigation instructions on the ground, such as Figure 5 As shown, users can quickly reach their destination based on the navigation instructions. Through this solution, users can be provided with clearer and more convenient navigation services, and this solution does not need to rely on the network (such as WIFI, global positioning system (GPS), etc.), so it is not affected by network factors, and high-precision navigation can still be completed in places with poor network such as basements and computer rooms.

[0063] Optionally, the building management system further includes a database layer 140. Figure 1 As shown, the present application stores data related to the building system in a dedicated database for access and use by the MR device 111 and other devices (such as an artificial intelligence (AI) server 132).

[0064] The database layer 140 includes a static database 141 and a dynamic database 142, wherein the static database mainly stores static data information related to the building system, such as the structural dimensions of the building system, thermal parameters of the building envelope, design parameters of the building system, location information of building equipment in the building, etc. These data information are mainly obtained from the three-dimensional model 112 of the building system. The dynamic database stores dynamic operation data information related to the building system, such as VAV operation data, AHU host data, real-time temperature field, etc. These data information are mainly collected by the local device layer 120 and sent to the dynamic database 142. For example, the local device layer 120 optionally also includes a data acquisition device 122, which is, for example, an Internet of Things (IoT) sensor, a gateway, and other devices. The data acquisition device 122 and the BMS 121 send their collected data to the dynamic database 142 respectively. It can be understood that the above example is illustrated by using two different databases to store the static data and dynamic data of the building system respectively, but the present application is not limited to this. For example, in some scenarios, the static data and dynamic data of the building system can also be stored in a hierarchical manner through one database, and the present application is not limited to this.

[0065] In a possible implementation, the MR device is connected to the database layer 140, so that the MR device 111 can extract data from the database layer 140 and display the data of the building system to the user. As an example, Figure 6 The example diagram of the VAV data visualization function of building equipment is shown. The user can send instructions to the MR device through the interaction method described above to open the VAV data panel. For example, based on the "eye tracking" function, the user looks at the VAV digital model and completes the "click" through gesture operation. After the MR device detects the user's operation, it reads the VAV real-time operation data from the dynamic database 142 and displays it as follows: Figure 6 The VAV data panel shown is directly and intuitively displayed in front of the user in the mixed reality environment. At the same time, the panel will track the user's head in real time to ensure that it does not leave the field of vision, thereby improving the user experience. This application does not limit the specific content displayed in the data panel. Figure 6 Just as an example, the following Figure 6 For example: VAVbox-72635 is the name of the VAV device, the device temperature is 25°C, the set temperature is 18°C, the air flow rate is 100.04, the valve opening (Valueopen) is 100, and the update time is 9:05:21. As another example, Figure 7The example diagram of the building system temperature field visualization function is shown. The user can send an instruction to the MR device to turn on the building system temperature field. The user can choose to view the temperature field of all areas or the temperature field of some areas. After the MR device detects the user's instruction, it reads the temperature field data of the building system from the dynamic database 142 and displays it as follows: Figure 7 Schematic diagram of the temperature field shown.

[0066] Through the above solution, the relevant data of the building system (including static data and real-time operation data) can be visualized. Compared with traditional building visualization technology, this management system realizes more novel visualization and interaction methods. Compared with traditional building management solutions, it can improve the work efficiency of operation and maintenance personnel and enhance user experience.

[0067] S220, the MR device sends a control instruction to the BMS via the relay server. Correspondingly, the BMS receives the control instruction from the MR device via the relay server.

[0068] Exemplarily, the MR device sends control information to the BMS through the relay server based on the instructions applied by the user to the model of the building system, and the control information is used to modify the operating data of the building system.

[0069] For example, when the user calls Figure 6 In the data panel shown, the set temperature value in the panel is directly modified. After the modification is completed, the MR device recognizes the instruction for modifying the temperature applied by the user to the VAV model, and then the MR device sends a control instruction to the relay server based on the instruction. The control instruction is used to instruct to modify the set temperature of the VAV. After receiving the control instruction from the MR device, the relay server forwards the control instruction to the BMS.

[0070] S230, the BMS modifies the operating data of the building system based on the control instruction.

[0071] Exemplarily, the BMS receives the control instruction from the MR device through the relay server, and then modifies the operation data of the building system based on the control instruction. If combined with the example of part S220, the BMS modifies the set temperature of the VAV device based on the control instruction.

[0072] Based on the above scheme, by building a relay server, the communication between the MR device and the BMS is realized, and based on the communication between them, the management system of this application realizes the two-way influence of the digital reality and the real world in the concept of digital twin. Building operation and maintenance personnel can directly modify the operating parameters of the specified equipment through the control function in the platform, and then judge whether the system operation status is good based on the actual operation performance of the building system. Users in the building can also use the remote control function to adjust the operation of the building system to achieve a more comfortable indoor environment, which greatly improves the convenience of managing the building system.

[0073] Optionally, the cloud server layer 130 further includes an AI server 132 , which is connected to the dynamic database 142 and the MR device 111 , respectively.

[0074] In one possible implementation, the AI ​​server 132 is used to predict the future operating data of the building system. Specifically, the AI ​​server 132 can predict the future operating data of the building system based on the distribution of each device in the building system and the current operating data of the building system. It is understandable that the MR device 111 can obtain the operating data of the building system from the dynamic database 142 through the AI ​​server 132, or directly obtain the operating data from the dynamic database 142, and this application is not limited. In one possible implementation, under normal operating conditions, the MR device 111 obtains the operating data from the dynamic database 142 through the AI ​​server, and in an emergency communication scenario, the MR device 111 can directly obtain the operating data of the building system from the dynamic database 142, thereby improving efficiency.

[0075] This application does not limit the way in which the AI ​​server predicts operating data. For ease of understanding, a possible example is given below:

[0076] For convenience, the following example uses the AI ​​server to predict indoor temperature. As mentioned earlier, the three-dimensional model of the building system provides static data such as the physical layout, pipeline information, and measurement point location information of the air-conditioning system, while the local device layer provides real-time measurement point data and energy consumption data of the air-conditioning system. The time series measurement data of each sensor itself has a time series correlation. At the same time, the positions of different sensor measurement points are related. Therefore, the real-time measurement data of different sensor measurement points have a spatial-temporal dependency. This spatial-temporal dependency can be represented by an adjacency matrix. As an example, Figure 8 As shown, Figure 8 The adjacency matrix in is a data structure used to represent the spatiotemporal correlation between different data points.

[0077] Fig. 9The present application shows a prediction model for indoor temperature. The model is based on machine learning methods of graph neural networks and recurrent neural networks. The central air conditioning system and the temperature distribution of the working area are modeled in the form of graph structure data. This technology can be used to predict the system operation status of the central air conditioning system at the next moment. Fig. 9 In the model shown, the input layer is the spatiotemporal correlation data (i.e. Figure 8 The output in the graph layer is then used to process the spatial relationship, and then the recurrent layer is used to process the time series. Finally, the fully-connected layer is used to output the result, which is the predicted indoor temperature field.

[0078] Based on the above scheme, the operation data of the building system at future moments can be predicted, so that the operation data can be optimized according to the preset strategy, or early warning of possible future failures can be given in advance. The following is an exemplary description of the application in these two scenarios with examples.

[0079] In the first example, an IoT temperature measurement point is added to the VAV workspace, and “human in the loop” temperature control is introduced. The indoor set temperature of the VAV terminal is reset based on the above-mentioned graph neural network model. This allows for more accurate temperature measurement. The temperature measurement points of traditional VAV terminals are installed near the ceiling, which is about 2 meters vertically away from the actual employee work area. This makes it difficult to measure the temperature distribution and thermal comfort of the workspace. In addition, the sensors on the VAV terminals do not cover all work areas, and the temperatures of some areas are not taken into account in the control logic.

[0080] Real-time system data is transmitted through Fig. 9 The graph neural network model shown in the figure obtains the workspace prediction value (i.e. Fig. 9 The output value of the model shown in the figure) is then used by the optimizer to optimize the indoor set point temperature of the VAV terminal using a genetic algorithm. The adjustment value of the indoor temperature set point considering the indoor spatial and temporal global thermal comfort can be expressed as:

[0081]

[0082] Among them, T IoT, and T Require, They represent the predicted value and required value of the temperature measuring point in the i-th working area respectively.

[0083] Based on the above scheme, the operating data of the building system can be adjusted intelligently to improve the comfort of users. For example, in the above example, the optimization control algorithm is used to improve the overall thermal comfort of the work area, thereby avoiding overcooling or overheating in local areas. Alternatively, personalized air supply can be achieved according to personal thermal comfort preferences, thereby improving indoor thermal comfort satisfaction.

[0084] In one possible implementation, the MR device can read and display the VAV temperature set point recommended by the optimization control algorithm, and the user and operation and maintenance personnel can use the remote control function to instruct the BMS121 to adjust the operating data of the building system. Alternatively, in another possible implementation, the AI ​​server can also be connected to the BMS121, and the AI ​​server can intelligently control the VAV temperature setting without manual intervention, which greatly improves efficiency.

[0085] In the second example, the AI ​​server will predict the temperature distribution of the work area in real time, alerting users to areas that are too cold or too hot in advance, or predicting equipment that may fail in advance.

[0086] Fig.11 The figure shows a temperature prediction result window provided by an embodiment of the present application. The AI ​​server can directly display the recommended set temperature and the VAV equipment for warning to the user. The user can modify the operating data of the building system based on the recommended value of the AI ​​server and quickly locate the abnormal equipment. The user can use the MR device to visually observe the location of the abnormal equipment, such as Fig.12 As shown, the circular area is used to mark the location of the fault.

[0087] Based on the above scheme, the operation data of the building system can be automatically adjusted intelligently and fault warnings can be issued, thereby saving monitoring costs and improving building management efficiency. For example, in traditional building management schemes, the main function is usually to display the real-time operation data of the building, lacking the function of in-depth analysis and prediction of the operation data. Existing building operation fault prediction and optimization control are mostly based on expert experience and rules. When implemented, it takes a lot of manpower and time to customize and develop the designated building system. The solution of this application can reduce costs and increase efficiency, so it has strong practical value.
