The granularity selected in the application can be described as that each leaf node of the tree-shaped operation model corresponds to a minimum operation step in the operation scheme, the step relates to a specific operation main body and a specific execution action of the operation main body, the execution action can be directly captured or judged by a computer system to be finished or not, if the operation step of X switch opening and closing is three times, the operation step of X switch opening and closing is divided into six operation steps of X switch opening and closing-1, X switch closing-2, X switch opening and closing-3, X switch closing-4, X switch opening and closing-5 and X switch closing-6, and the nodes corresponding to the six operation steps are sub-nodes of the node corresponding to the operation step of X switch opening and closing three times.
The basic implementation of the method, system and apparatus described in this application is first described below by way of example only.
Example 1
The embodiment of the application firstly provides a scheduling method for operation display of power grid equipment, as shown in fig. 1, the method can comprise the following steps:
s101, building a commissioning model file according to a commissioning scheme, wherein the commissioning model file at least describes a tree-shaped commissioning model containing a time sequence relationship, and each node of the tree-shaped commissioning model corresponds to an operation step in the commissioning scheme, wherein the operation step should be displayed in the commissioning state.
In specific implementation, all steps in a commissioning scheme are split into a plurality of minimum operation steps, the minimum operation steps meet a granularity minimum principle, namely, the minimum operation steps cannot be split continuously in a power enterprise regulation and information management system, the typical commissioning scheme is described as 'station A commissioning … … commissioning process … … is used for performing impact switching on an AB line three times by using a station AB line AB switch, and finally the switch is at a switching-on position', according to the relevant regulation of power scheduling control, the step is not the minimum operation steps, and the steps are split into a 1-station AB line AB switch-switching-on step, a 2-station AB line AB switch-off step, a 3-station AB line AB switch-switching-on step, a 4-station AB line AB switch-switching-off step, and five minimum operation steps with successive connection relations are described in a commissioning model file.
In particular, the built tree-like commissioning model may include a tree structure with a depth of at least 4 as shown in fig. 2, where each node represents a step involved in scheduling, and the predecessor and successor relationships between each node are consistent with membership relationships between each step, that is, steps corresponding to all child nodes in the tree structure are part of steps corresponding to parent nodes, and obviously are part of steps corresponding to grandparent nodes, for example, a first layer root node commissioning name may be "a station commissioning", and a second layer child node "1, new equipment report completion", "2, preparation before commissioning", "3, and commissioning process" all belong to a part of the process of "a station commissioning". The sequence number before each node represents the timing identity of this step.
It should be noted that the minimum operation steps corresponding to the leaf nodes (i.e., the nodes having zero degrees, i.e., the nodes having no child nodes) include the object to be operated and the operation completion actions for the object, such as "dispatch log recorded", "open XX knife gate", "rewind XX line to XX bus operation" of the fourth layer in fig. 2, wherein the object objects are "dispatch log", "XX knife gate", "XX line", respectively.
The tree commissioning model may be stored in a conventional manner of storing a tree structure, such as in a formatted text or database link table.
In specific implementation, the commissioning model file may be a file stored in a long-term storage device, such as a hard disk, a memory card, or may be a virtual file stored in a temporary storage device, such as a memory, a cache, or the like. The commissioning model file may be a tree-shaped commissioning model described in text, where the above-mentioned commissioning model file includes "the a-station commissioning … … commissioning process … … is to use the a-station AB line AB switch to switch on the AB line three times, and finally the corresponding commissioning scheme of fig. 2 described in the closing position … …" and the like, and may be expressed as follows in the text-form commissioning model file:

It can be seen that each record in the text file corresponds to a leaf node, while each record contains 14 columns of data items, wherein each data item can satisfy the following definition:
the first column, the project name (i.e. "station A project") used to distinguish this project from other projects in the database, in the same project scheme, this term is always the same;
the second column, major item name, indicates to which major item the operation belongs, the major item is the stage of three commissioning processes divided by human, in this embodiment, three items of "new equipment report completion", "commissioning preparation" and "commissioning process";
the third column, the small item number, indicates the execution order of the small items to which the present line belongs: the same sequence number represents that these two children will execute simultaneously as planned; the different sequence numbers indicate that the two items are to be executed in succession as planned. For example, a minor number of 1 for "floor completion" and "floor completion" indicates that they are running simultaneously and the program will capture their information simultaneously; if the two small item numbers are 1 and 2, respectively, the former is performed first, and the latter is performed later, the program unit of the system of the embodiment may be configured to capture the information of the former first, and capture the information of the latter after the completion of the former;
the fourth column, the minor item name, which indicates which minor item the present line belongs to, the minor item is a specific operation concerned by the dispatcher, such as 'three impact switch-on operations';
the fifth column, shift operation number, indicates the order of shift operations represented by the present row in the small item. When the program captures the displacement operation, only the current operation to be performed, such as the switching-on, switching-off, switching-on, switching-off and switching-on of the same switch, including 5 displacement operations in three times of impact switching-on, wherein the displacement operation serial numbers of the displacement operations are 1,2,3,4 and 5 respectively, and if the switch has been switched on and off once, the items with the displacement operation serial numbers of 1 and 2 are captured, and the program tries to capture the switching-on operation of the switch with the displacement operation serial number of 3;
a sixth column, a station ID, which represents an ID of a station to which the switch knife in the operation of the present line belongs, the ID being unique in the model center database;
seventh column, the name of the station, which indicates the name of the station to which the switch knife in the operation of the present line belongs;
an eighth column, equipment ID, representing the ID of the switch knife in the operation of the present row, which is unique in the model center database;
a ninth column, a device name, which indicates the name of the switch knife in the operation of the present row;
a tenth column, device class, indicating whether the device that is displaced in the present line operation is a switch or a knife switch;
an eleventh column, whether to collect, represent whether the present line captures the shift information of the switch knife switch, if not, the present line judges whether to finish by other modes;
twelfth column, deflection information, which indicates the direction of deflection of the switch knife switch in the operation of the present row, can be defined as 1 being closed and 2 being opened;
a tenth column, estimated time, recording the estimated time in minutes for the small item in which the line is operated;
fourteenth column, keyword, which is keyword content when the keyword gathering mode is adopted instead of the displacement information capturing mode. Wherein the separate parts represent different keywords, and the completion of the line operation is judged only when all keywords are collected in one piece of information.
In the above data items, the third column and the fifth column respectively correspond to the ordered identifiers of the nodes of the third layer and the fourth layer in the tree operation model of fig. 2, and the nodes of the fourth layer are all leaf nodes because of no branch, and meanwhile, the nodes of the first layer and the second layer are fewer in number, and each front-back sequence relationship recorded in the text file can represent the execution sequence thereof, so that omission is made. Obviously, the number of records in the text file is consistent with the number of leaf nodes.
In another embodiment of the present application, the commissioning model file may also be in the following form:
“……

……”
The difference between this embodiment is that, in the three records shown, the first and second records have a parallel relationship, and the third corresponding minimum operation step must be started after the normal execution of the first two corresponding minimum operation steps.
In other embodiments of the present application, the commissioning model file may also be a data table in a database, and those skilled in the art will easily design a corresponding data table according to the above description to meet the above requirements.
S102, reading a commissioning model file, establishing a progress information variable uniquely for each node of the tree-shaped commissioning model, and updating the progress information variable of the leaf nodes in the tree-shaped commissioning model according to a time sequence relationship contained in the tree-shaped commissioning model.
When the method is specifically implemented, the described tree-shaped operation model is read from the operation model file in a file form or a database form, a tree-shaped data structure of the tree-shaped operation model is built in a memory and used for recursively traversing nodes of the tree-shaped operation model, and meanwhile, a progress information structure variable is built for each node of the tree-shaped operation model in the memory, wherein the structure variable at least comprises the estimated completion time, the actual completion time and the state identification of the node, and the estimated completion time, the actual completion time and the state identification can be variable, array or reference type respectively.
The data sources for updating the progress information of the leaf nodes in the memory are classified into two types according to whether the state of the object can realize automatic acquisition, wherein the first type is step information which can be obtained by reading an interface of an existing automation system such as a dispatching center core database, for example, the running state information of the power equipment which is the object in the step, and the second type is step information which cannot be obtained by reading an interface of an existing automation system such as a dispatching center core database, for example, the steps of 'manual setting', 'reading a log', 'reading a maintenance work ticket', 'reading an operation command ticket', and the like, and automatic information acquisition is not realized in an electric enterprise. The leaf nodes are marked according to the difference of the data sources, and the marking method can be that a variable of whether the flag bit is collected or not is set for each leaf node, and the variable can be of a Boolean type. When updating, the progress information of the leaf nodes is updated in sequence according to the time sequence of the mark of the tree-shaped operation model, and when the step represented by the prior leaf node is completed, the corresponding step of the immediately following leaf node is judged; when there are parallel related leaf nodes (especially the common preceding leaf node and the common following leaf node), after the steps represented by the common preceding leaf node are completed, the judgment of the parallel related leaf nodes is started, and after the parallel related leaf nodes are completed, the judgment of the common following node is started.
