In this embodiment, the electrical components of the power supply network system of the building engineering include a distribution box, a cable, a pre-branching cable, a bus duct, a T-connection terminal, a cable conversion box, a pre-branching connector, a pre-branching hook, a bus jack box and a bus terminal box, which are common knowledge in the art, and the present embodiment does not make unnecessary description, and it should be noted that, in the power supply network system of the building engineering, the electrical components include at least two kinds of the above components, for example, for the building engineering with lower requirement on the power supply voltage, the electrical components may include only two kinds of the distribution box and the cable, and accordingly, for the building engineering with higher requirement on the power supply voltage, the electrical components may include two kinds or more of the above electrical components.
Further, based on the general knowledge of the above electrical components and power supply, the distribution box is a total circuit distribution box for all users to use electricity, and thus, a layer of network topological structure relationship based on the electrical components is that the distribution box is used as the first layer, and each low-voltage power supply is connected through a plurality of cables. Correspondingly, the multi-layer network topological structure relationship based on the electrical components can be formed by three or more of a distribution box, a cable, a pre-branching cable, a bus duct, a T-connection terminal, a cable conversion box, a pre-branching connector, a pre-branching hook, a bus jack box and a bus terminal box. The specific structural relationship is determined based on the power supply requirement of the actual building engineering, and redundant description is omitted in this embodiment.

In this embodiment, the one or more layers of network topological structure relationships correspond to corresponding tree structures of the power supply network, for example, the distribution box is used as a node, the cable is used as a path, and the bus duct, the T-connection terminal and the like are correspondingly used as electrical members on the path, so that three tree structures of the power supply network including the radial power supply network, the trunk power supply network and the chain power supply network can be obtained.
In one embodiment, the radial power supply network includes cable radial power supply and busway radial power supply; the trunk type power supply network comprises a T-connection trunk type power supply, a pre-branch tree dry type power supply and a bus duct tree dry type power supply; wherein the electrical member of the T-junction trunk power supply comprises a cable and a T-junction terminal; the electrical components of the pre-branching tree dry type power supply comprise a pre-branching cable, a pre-branching connector, a pre-branching hook, a cable conversion box and a cable; the electrical components of the bus duct tree dry type power supply comprise a bus duct, a bus jack box and a bus terminal box; the chain supply network comprises a cable chain supply.
In this embodiment, the types of power supply included in the radial power supply network, the trunk power supply network and the chain power supply network are known to those skilled in the art, and accordingly, the electrical components included in the power supply networks of different power supply types are also different, which are relatively common power supply modes at present, so that the operation and effects thereof will not be described in detail in this embodiment.
In one embodiment, the specific process of establishing the parent-child node relationship table and the path relationship table is as follows: taking a distribution box as a node, taking the distribution box connected with the starting point of a path component of the radial power supply network as upper-level ID information, and taking the distribution box connected with the end point of the path component as lower-level ID information; taking a distribution box connected with a starting point of a path member of a trunk type power supply network trunk line as upper-level ID information, and a distribution box connected with a branch line terminal point as lower-level ID information, wherein the trunk line and the branch line encapsulate the same upper-level ID information and lower-level ID information; taking a distribution box connected with a starting point of a path member of the chained power supply network as upper-level ID information, and taking a distribution box connected with a middle point and a terminal point as lower-level ID information;
generating a path relation table according to an upper-level ID information set and a lower-level ID information set of all path members of the radial type power supply network, the trunk type power supply network and the chain type power supply network;
and taking the upper-level ID information of the same path members of the radial power supply network, the trunk power supply network and the chain power supply network as father nodes and taking the lower-level ID information of the same path members of the radial power supply network, the trunk power supply network and the chain power supply network as child nodes, respectively storing the father nodes and the child nodes into an upper-level distribution box ID set and a lower-level distribution box ID set of the distribution box, and generating a father-child node relation table.
S103, searching the father-son node relation table by adopting a depth-first search algorithm to obtain node load capacity; the node load capacity refers to the load capacity which is transmitted to the head node from the last node of the power supply network tree structure in a step-by-step superposition mode.
Specifically, in one embodiment, before searching the parent-child node relation table using the depth-first search algorithm, the method further comprises: judging a head node and a tail node of a tree structure of the power supply network; the judging of the head node specifically comprises the following steps: storing all path component ID information taking a distribution box as a lower level as an upper level cable set; in the radial power supply network and the chained power supply network, if the path component ID information of the upper cable set of the distribution box node comes from low voltage, the distribution box node is the head node; in a trunk type power supply network, if a superior cable set of a distribution box node is connected as a branch line, and path member ID information of a trunk line of the branch line connected through trunk type logic comes from low voltage, the trunk type power supply network is a head node; the decision of the end node is specifically: storing all path component ID information taking a distribution box as an upper level as a lower level cable set; and if the lower-level distribution box ID set of the distribution box node is zero and the number of the lower-level cable sets is zero, the distribution box node is a terminal node.
Accordingly, in a further embodiment, a depth-first search algorithm is used to search the parent-child node relation table to obtain a node load capacity, which specifically includes: traversing from all the head node distribution boxes to the tail node distribution boxes, setting the load capacity of the current node distribution box to be 0, globally searching for the lower-level distribution boxes, taking the sum of the capacities of all the lower-level distribution boxes as the node load capacity of the current node distribution box, and continuing traversing the overlapped capacities of the lower-level sub-nodes in a recursion mode if the lower-level distribution boxes of the current node distribution box exist, until a preset return condition is reached; and if the node distribution box ID information exists in the terminal node set, returning the terminal node distribution box capacity, wherein the terminal node distribution box capacity is not set to 0.
In this embodiment, it should be noted that, when performing the depth-first search, the deduplication operation needs to be performed on all the path relationship tables and the parent-child node relationship tables, so as to prevent the repeated search of the depth-first search algorithm.
And S104, determining the load capacity information of the path member according to the node load capacity and path relation table, and transmitting the load capacity information to a low-voltage power distribution cabinet for load management and load distribution.
Because the load capacity of each node distribution box is already determined, the load capacity information of the electric components on the path can be determined only according to the path relation recorded by the path relation table, and therefore the load management and distribution can be completed according to the high-to-low voltage distribution standard.
In summary, the load capacity transfer method of a power supply network system in a building engineering provided by the embodiment establishes a parent-child node relation table and a path relation table of a path component of a power supply network tree structure based on a traditional power supply network system topology structure and electrical components thereof, searches the parent-child node relation table by adopting a depth-first search algorithm to obtain node load capacity which is transferred to a head node from a tail node of the power supply network tree structure in a step-by-step superposition manner, determines load capacity information of the path component based on the path relation table and the node load capacity, and transfers the load capacity information of the path component until the load capacity information is transferred to a low-voltage cabinet, thereby improving accuracy and high efficiency of electrical design.
