Embodiments of the present application will be described below with reference to the accompanying drawings.
It should be noted that the execution subjects of the following method embodiments may be an entity organization tree construction device in a building control system and an entity invocation device in the building control system, respectively, and the device may be implemented by software, hardware or a combination of software and hardware to become part or all of the above computer equipment. The following method embodiments are described by taking the execution subject as the computer device as an example.
Fig. 2 is a method for constructing an entity organization tree in a building control system according to an embodiment. The embodiment relates to a specific process for automatically constructing an entity organization tree by computer equipment. As shown in fig. 2, the method includes:
s11, constructing a hierarchical entity organization tree according to the position relation among a plurality of entities in the building control system; the entity organization tree comprises a plurality of nodes, and the nodes correspond to the entities one by one.
Specifically, the computer device may construct an entity organization tree according to a position relationship between entities in each building control system, where the entity organization tree includes nodes, and each node corresponds to one entity. Because the entity can be described hierarchically through the position relationship, the node corresponding to the entity can present a hierarchical relationship, and the constructed entity organization tree can be hierarchically constructed based on the hierarchy of the position relationship, that is, the hierarchical entity organization tree. One possible form of the entity organization tree can be seen in fig. 2 a.
S12, adding custom tags to the nodes in the entity organization tree; wherein the custom tag comprises an extended attribute tag.
Specifically, the computer device adds a custom tag to each entity in the entity organization tree. The custom tag may be an autonomously defined tag, and may include an extended attribute tag, such as a personalized tag added by a user, which may be any content edited by the user for a corresponding node, and is not limited to the previously set tag content; optionally, the custom tag can be edited, modified, copied, moved, deleted, etc. For example, an extended attribute tag with a purchase date of XX year, X month and X day may be added to the node AHU-1-1 in FIG. 2a for monitoring maintenance and repair of the entity AHU-1-1. Optionally, the extended attribute tag may also represent an association relationship between entities in a key-value pair manner, such as a functional upstream-downstream relationship. For example, if the air conditioner needs to exhaust air through the exhaust duct, the air conditioner is functionally an upstream device of the exhaust duct, and the key value pair may be used to represent the relationship that the air conditioner is the upstream device of the exhaust duct. Optionally, the extended property tag may be a property tag, which may extend a property of the entity, for example, different extended property tags may be added for different building control items, different energy consumption systems (such as air conditioning systems, lighting systems, metering systems, etc.), different models of devices, and different processing logic. The embodiment does not limit the specific information of the entity represented by the custom tag.
In this embodiment, the computer device constructs a hierarchical entity organization tree according to a position relationship between a plurality of entities in the building control system, where the entity organization tree includes a plurality of nodes, the nodes correspond to the entities one-to-one, and the computer device adds custom tags to the plurality of nodes in the entity organization tree. The method adopted by the embodiment can enable the nodes in the entity organization tree to carry the custom tags comprising the extended attributes, so that the nodes in the same entity organization tree can be described in multiple dimensions based on the custom tags, the problem of entity redundancy caused by the fact that multiple organization trees are generated due to the fact that the nodes are described in multiple dimensions can be avoided, the data volume of a building control system is greatly reduced, and the entity can be called more conveniently and rapidly. Meanwhile, after the user-defined tag is introduced, the method can be flexibly used in the aspects of data screening conditions, new statistical dimensionality increase, statistical item expansion and the like in the entity calling process.
Optionally, on the basis of the foregoing embodiment, the custom tag further includes a fixed attribute tag; one possible implementation manner of the step S12 may further include: adding a fixed attribute label to the node corresponding to the entity in the entity organization tree according to the attribute information of the entity; wherein the attribute information is used to characterize at least one of a category, a model, and a quantity of the entity. Alternatively, the fixed attribute tag may be referred to as a marker tag, or may be referred to as a classification tag or a mark tag, where the classification tag has no attribute value but only a tag name. For example, the answer label and the AHU label, model labels can be added according to different models of entities under the node corresponding to the AHU label, so as to meet the requirement that a user can freely call and classify each node according to actual requirements. In this embodiment, since the custom tag may further include a fixed attribute tag, in the process of building the entity organization tree, the fixed attribute tag may be added to the corresponding node according to attribute information representing at least one of the category, the model, and the number of the entity, so that the entity can be called more accurately, conveniently, and quickly based on the fixed attribute tag, and further, the calling flexibility is enhanced in the aspects of data screening conditions, adding new statistical dimensions, expanding statistical terms, and the like, and the application scenarios are richer.
Optionally, on the basis of the foregoing embodiments, the extended attribute tag includes: boolean labels, numerical labels, string labels, time labels, and reference labels; and the reference label is used for characterizing the incidence relation between the entities corresponding to the nodes in the using process. Specifically, extended attribute tags include, but are not limited to: boolean (Boolean) tags, i.e. 1 or 0, for characterizing yes or no; numerical (numerical) tags, such as specification parameters; string tags, such as device name; a time (DateTime) tag, such as a time of purchase or time of installation, etc.; and reference (RefID) tags. The multi-dimensional relationship between the entities can be represented by referring to the tags, that is, various relationships binding the entities and other entities, that is, the association relationship in the use process, such as the upstream and downstream relationships of the device, and different association relationships can be distinguished by tag names. For example, the attribute tag may be as shown in FIG. 2 b. Since the attribute tag includes: the computer equipment can call the entity in a plurality of different dimensions through different attribute tags, so that the calling mode of the entity is more flexible and comprehensive, and the application scene is richer.
Optionally, the entity is an entity in any one of a building system and an energy consumption system; wherein the energy consumption system comprises at least one of a lighting system, an air conditioning system, or a metering system. For example, the entity may be a lamp of a lighting system in an energy consumption system, an air conditioning device, etc.
Optionally, on the basis of the foregoing embodiments, the method may further include: updating the custom tag into a preset editor; wherein the editor comprises any one of a logical editor, a graphical editor, and a graphical page. Specifically, the computer device may update the custom tag of each entity into a preset editor, so that the entities in the editor carry their own custom tags. For example, the computer device may combine the marker tags into a filter condition, screen out a target entity to which a current logical editor, a current graphic editor, or a current graphic page is to be applied, and load a unit (such as a point location, attribute information, and the like) to be used in the logical editor, the current graphic editor, or the current graphic page to the target entity. After the editor is configured, the editor can be applied to all target entities in an extension mode, so that the purpose of configuring multiple places for use at one time is achieved, and the operation efficiency of engineers is greatly improved. Meanwhile, due to the expansibility of the user-defined tag, the editor has stronger universality and expandability, and further application scenes are richer and more flexible.
In the above embodiments, how the computer device establishes the entity organization tree is described in detail, and a specific process of how the computer device invokes the entities in the entity organization tree is described in detail below.
Fig. 3 is a method for entity invocation in a building control system according to an embodiment. As shown in fig. 3, the method includes:
s21, receiving a query request; wherein, the query request carries the common attribute of the entity to be queried.
In order to manage all entities in a building control system, an entity organization tree of the entities is usually established according to one relationship between the entities, that is, a plurality of entities are arranged according to a tree structure, and each node in the entity organization tree represents one entity. The entities corresponding to the other nodes under each node have a corresponding relationship with the node, such as a positional relationship, for example, the entities corresponding to the other nodes under each node are located inside the node. One possible form of the entity organization tree for each node is shown in fig. 2 a.
Specifically, the computer device receives a query request input by a user or a query request of other systems needing to invoke the entity. Wherein, the query request carries the common attribute of the entity to be queried. For example, when the electric meters on the X-th floor need to be queried, the common attributes carried in the query request include the electric meters and the attributes of the X-th floor, and the computer device can know that the entity needing to be queried is all the electric meters in each room on the X-th floor through the query request.
S22, searching the self-defined attribute tag of the entity to be queried in the entity organization tree in any of the above embodiments according to the query request, and obtaining a target entity set matching with the query request.
Specifically, the computer device queries the custom tags of all entities to be queried in the entity organization tree according to the query request, and then screens out the entities matched with the custom tags and the query request as a target entity set, wherein the entities in the target entity set all have common attributes. Alternatively, the entity organization tree may be as described in any of the previous embodiments.
The technical principle and the beneficial effects in the present embodiment can be referred to the description in the foregoing embodiments, and are not described herein again.
Optionally, on the basis of the foregoing embodiment, the method may further include: and performing diagrammatized display on the entities in the target entity set, such as energy consumption proportion ranking, energy consumption trend, energy saving effect and the like. The computer device may perform a diagrammatized display on the determined entities in the target entity set, for example, generate a corresponding table, where the table includes information of a name, a belonging location, a belonging functional system, a device type, and the like of each entity in the target entity set. Of course, the computer device may also perform topology display on the entities according to an association relationship, such as a connection relationship, of a certain dimension between the entities in the target entity set, for example, generate a topological graph of air conditioner distribution. In this embodiment, the computer device performs diagrammatized display on the entities in the target entities, so that the entities to be queried, which need to be queried, can be visually and clearly presented according to the query request, and the query result is visualized, thereby further facilitating the use of the user.
