[0043] like Figure 1 and 2 As shown, the present invention provides a method for formulating a strategy for equipment operation in a building, the method comprising:

[0044] Step 1: Establish a data template for the equipment object model in the building and the attributes in the equipment object model;

[0045] Step 1.1: Define equipment attributes and equipment numbers, and classify equipment in the building, such as lighting equipment, HVAC equipment, curtain equipment, security equipment, and fire protection equipment, etc., to form equipment object models for each category. , i represents the category number of the device object model, defining each category of the device object model The attribute set is , j represents a device model of a certain category i The ordinal number of the attribute.

[0046] Specifically, each category of equipment model The attribute set may include: power, brightness, temperature, wind speed, etc.

[0047] Create an equipment object model for the indoor air conditioner, which has a switch. , set temperature ,model , wind speed and return air temperature Five attributes.

[0048] like Figure 3 As shown, step 1.2: Define the state query data template of the device object model, that is, determine the data type of the attribute field of each device (string, bool, number, etc.), field name of the attribute (field names such as up, down, SetTemperature, etc.), for the attribute set defined in step 1.1, the attribute The data template includes: attribute name , Data Type , attribute field name , The data template is represented as a triple ,

[0049] Specifically, each attribute Each has a unique identifier , and the corresponding values ,

[0050] Define the data types and data constraints of each attribute of the air conditioner, for example:

[0051] Switch Properties , set to bool attribute, 0 means the air conditioner is off, 1 means the air conditioner is on;

[0052] Setting Temperature Properties , used to control the temperature of the air conditioner, set to number value type;

[0053] Mode properties , set to string type, use "1" for cooling, "2" for heating, "3" for ventilation, and "4" for automatic;

[0054] Wind speed attributes Set it to string type, "1" is set to low wind, and "2" is set to high wind.

[0055] After setting the data template of the attributes in this way, the attributes of air conditioners of different models and types in the building can be mapped to the air conditioner object model, avoiding the problem of repeated creation of different types of air conditioner controls.

[0056] Step 2: Collect sensor data of the status of each device in the building according to the format of the data template of the attribute in the device object model;

[0057] like Figure 4 As shown, step 2.1: Through the building automation system, various devices in the building are integrated, and the status information of the device instances is periodically published through the sensors, controllers and communication networks corresponding to the various devices, and the MQTT protocol is used. At the same time, the building automatic control system subscribes to the MQTT controlled by the device for the control of the device object model instance.

[0058] The sensor data of the status of each device in the building is converted into the physical model attribute format defined in step 1. , periodically publish to MQTT, and subscribe to the MQTT Topic of device control to receive control instructions.

[0059] Step 3: Based on the equipment information in the electromechanical BIM digital twin model, the equipment object model and the data template of the attributes in the equipment object model, create an equipment object model instance, wherein the equipment object model instance includes spatial information; configure the status query information of each attribute of the equipment object model instance, and enter the control information of each attribute of each equipment object model instance;

[0060] Step 3.1: Read the equipment information in the electromechanical BIM digital twin model and create an equipment object model instance Based on the device information, the corresponding category of the device is obtained. Based on the corresponding category of the device, each device is associated with a building model of the corresponding category. Binding to form a device object model instance , device object model instance Inherit the building model corresponding to class i All properties and object model attributes in the format ;Wherein, w represents the device serial number in the device object model of type i;

[0061] Specifically, the type of equipment can be read from the BIM electromechanical digital twin model, and the corresponding equipment object model instance can be created according to the type of equipment.

[0062] Step 3.2 Read the equipment space information in the electromechanical BIM digital twin model and bind the spatial attributes of the equipment object model instance , each device object model instance Divided into the corresponding rooms of the building, Add spatial attributes to the attribute information ,get .

[0063] Here, the architectural BIM model and the electromechanical BIM digital twin model can be combined to read the spatial data corresponding to the equipment. For example, the room corresponding to the air-conditioning equipment instance "AHU-1-2" is read as "Conference Room 2401" as the spatial attribute. .

[0064] Step 3.3: Obtain the device object model instance from the building automation system Sensor data of device status Instances of device object models The attribute information is mapped to configure the device object model instance The status query information of each attribute of the device object model instance is entered, and the control information of each attribute of the device object model instance is entered. The attribute information of ,in For device object model instance The status information query method of the attributes (including the host, port and topic corresponding to Mqtt), Control information for the device's attributes (including the host, port, and topic corresponding to Mqtt).

[0065] Specifically, Figure 4 As shown in the figure, the state query information and device control information of each attribute of the "AHU-1-2" equipment object model instance are configured. The control flow is controlled by querying the control information.

[0066] Step 4: Based on the device object model , create object model nodes in the visual programming engine;

[0067] like Figure 5 As shown, step 4.1: In the visual programming engine, this solution uses NodeRed as the visual programming engine. For the device object model defined in step 1 , for each device object model Corresponding to encapsulating a node , The property information is inherited from , and One-to-one correspondence, each node contains two modes, device object model The state query mode of the property and device object models The control mode of the property , where p represents the serial number of the status query mode and q represents the serial number of the control mode.

[0068] like Figure 5 As shown, create an air conditioning model node , the properties of the node and the device object model in step 1 One to one correspondence.

[0069] Step 4.2: For control mode , add device control recording function to record each device control operation for log management of policy execution.

[0070] Step 5: Develop a control strategy for each node and deploy the spatial information of the control strategy instance;

[0071] Step 5.1: Utilize the node created in step 4 , formulate device control strategies, and drag device object models in the flow-based visual programming engine Node , through the connection of the visualization engine, create data flow and control flow to form a device control strategy The strategy consists of a physical model status query node, a physical model control node, and a custom data editing module. .

[0072] For example, you can query the status of the switch properties of a light. For example, to query the status of the switch properties of the air conditioner; For example, it can be used to control the air conditioner; For example, it can be used to turn off the air conditioner;

[0073] For example, Figure 6 As shown, a strategy is developed during the workday to turn on the air conditioner after the lights are turned on: Afterwards, if the air conditioner is found to be off, , then turn on the air conditioner At the same time, formulate a strategy to turn off the air conditioner after the lights are turned off: when the lights in the space are turned off Afterwards, if the air conditioner is found to be on, , then turn on the air conditioner control. Figure 6 As shown in the figure, "Light Status" is a query node (the creation of light nodes is the same as air conditioning), which is used to query the status of lights in the space. The first two air conditioning nodes are query modes, which are used to query the current air conditioning status. The last two air conditioning nodes are control modes, which control the air conditioning in the conference room after meeting the conditions.

[0074] Step 5.2: Using the control strategy created in step 5.1 As a policy template, deploy different control policies to different spaces and create multiple policy instances , as a strategy running in space, adding space attributes to the strategy instance , update the policy instance to

[0075] .

[0076] Here, after creating the policy template, deploy the policy, for example, deploy the conference room air conditioning policy to rooms with the same space attributes. Device object model example , if the spatial attributes are the same "Conference Room 2401" forms a policy instance, which has the spatial attributes of "Conference Room 2401".

[0077] Step 6: Based on the status query information and control information in step 3, and based on the policy instance in step 5 , to execute the control strategy;

[0078] Step 6.1: Policy Example During the execution of With control mode , spatial information will be added , through spatial information , get the same Thing Model Device Instance of Properties , through the device object model instance in step 3.3 Method for querying status information in the properties of and control information , query and control the status of specific types of equipment in a specific space, and implement the control strategy for the equipment in the corresponding space.

[0079] Here, when the air conditioning policy instance of the conference room "2401 Conference Room" After execution, the created device object model instance will be matched It also has the spatial attributes of "Conference Room 2401" The lighting object model instance and the air conditioning object model instance will query the status of the lighting instance and then determine whether the air conditioning in the "Conference Room 2401" needs to be turned on or off.

[0080] Step 6.2: Using spatial information Strategy instantiation for dimensions Through the aggregation of information, strategies in the building space are centrally managed, and the operation results of the control strategies executed in each space are monitored.
