Example three:
the embodiment provides a system and a method for automatically generating an electrical drawing in real time. The hardware framework of the system provided by the embodiment is shown in fig. 2.
The embodiment is provided with a plurality of power distribution system managers which can be installed on power distribution cabinets of different types. The manager can collect various electrical data in the corresponding power distribution system, has a good man-machine interaction function, and uses the Ethernet to exchange data with the server. The manager system software introduces a data structure of a bill of materials, and the specific implementation idea is as follows: the electrical configuration in the electrical panel has a certain regularity, so that the summary of the electrical equipment in common use is given in fig. 3. In the embodiment, the common electrical equipment is divided into 4 major categories, which are respectively: the system comprises a power access point, power transformation equipment, disconnection equipment and other equipment. The materials are further subdivided according to the characteristics of each device, and a total of 56 subdivided materials are finally obtained, the material classification is shown in fig. 11, and the manager program records the names, default models, default specifications (length, rated current, precision), simplified diagrams, device electrical models and other data of the materials in 56 in advance. When a user uses the manager for the first time, the user needs to manually input the power distribution equipment in the power distribution cabinet in sequence, the user inputs the adding equipment one by one according to the configuration condition in the actual power distribution cabinet, and finally a bill of materials of the power distribution cabinet is formed.
The administrator will keep a bill of materials entered by the user and will automatically upload to the server over the ethernet. A complete set of power distribution system is composed of a plurality of power distribution cabinets, a manager of each power distribution cabinet can provide a corresponding list for a server, and the server draws a complete drawing through data after data aggregation. In this embodiment, the method is called as distributed bill of material editing and storage, and the essence is that the data of the whole power supply and distribution drawing is uploaded by the manager of each cabinet in a way of breaking up the whole part.
The manager, while uploading the bill of materials, also transmits a switch number, e.g., "# 1", to determine the switch location and data classification.
The hardware structure of the manager is shown in fig. 4, and the main chip of the manager is a 32-bit ARM architecture single chip with built-in high-speed AD (analog-to-digital conversion) and DSP units. The secondary signals collected by the voltage and current transformer are properly conditioned, filtered and voltage raised, and then are transmitted to the singlechip. The inside of the single chip microcomputer is converted through a high-speed AD unit and then is subjected to data processing through a DSP unit, and effective values (0 time is a direct current component, and 1 time is a fundamental component) of 0-31 times of harmonic waves of each path of voltage and current can be obtained. Strong electric switch signals, such as a voltage loss alarm signal and a closing loop opening loop signal, are all 110V-220V, and the on-off detection of the singlechip on the strong electric switch signals and the closing loop opening loop signals is realized by driving an optocoupler after passing through a current-limiting resistor. Other passive switch signals, such as knife switch handcart signals and the like, directly control the optical coupler to be connected so as to realize the detection of the singlechip on the signals. The EEPROM is used for storing system parameters, user configuration parameters and electric quantity information. The external flash is used for storing alarm information fault recording data, protection fixed value data and bill of material data. The USB serial port is used for communicating with an upper computer. The CAN interface is used for exchanging data with other managers, the RS485 interface is used for exchanging data with the dehumidifier, and the Ethernet is used for exchanging data with the server. The manager provides good human-computer interaction logic so that the user can edit the bill of materials more conveniently. The manager material entry interface is shown in fig. 5, the left column is the title sorting of the materials, and the right side after the selection of the corresponding component is the detailed information of the component, including the name, model, specification, rated current, length, and precision attributes of the component. Different types of components have different attributes. The manager can support editing and storage of 28 materials (the manager of the reactive compensation cabinet can provide editing and storage of 150 materials).
The manager is installed on the power distribution cabinet to monitor the power distribution system of the whole power distribution cabinet, and the application scene of the manager is shown in fig. 6.
The server is connected with the manager through the Ethernet, and the server software completes the function of automatically drawing the electrical drawing according to the electrical data uploaded by the manager; as shown in FIG. 7, the server software is divided into three blocks-front-end software, back-end software, and socket service. Wherein the front-end software is run on the browser of the user equipment and is a direct execution part of the drawing of the electrical diagram. The back-end software and the database are used for realizing data processing logic in the whole set of software. Socket service is used to implement the function of server and hardware (manager) communication.
The whole part of the whole distribution electrical drawing is broken into parts and stored in each manager hardware, each manager stores a bill of materials of a power distribution cabinet where the manager is located and transmits the bill of materials to a server through Ethernet, and the server can begin to draw a complete electrical drawing after acquiring the serial number of each power distribution cabinet and the bill of materials of power distribution equipment in each power distribution cabinet. Data to be processed for a server can be classified into three categories: power distribution cabinet characteristic data, component data in the power distribution cabinet and electrical data. Firstly, the characteristic data of the power distribution cabinets is mainly input by a user, such as the number of the power distribution cabinets, the number of each power distribution cabinet, the type of each power distribution cabinet and a manager identification code (BID) on each power distribution cabinet, and the characteristic data is filled by the user through a mobile terminal. The server extracts the characteristic data of one power distribution cabinet each time when drawing the electrical diagram each time, and then extracts the component data in each power distribution cabinet together to enter the drawing process.
As shown in fig. 8, the data type related to the power distribution cabinet is composed of a number, the number of components, details of the components, a mounting position, a type, a title, and a unique identifier. The number marks the number of the power distribution cabinet on the electrical drawing, for example, the type of "# 1-1", the number of the components indicates how many components are in the power distribution cabinet, and each component contains more details. The serial number, the number of the components and the details of each component are uploaded by the manager. The installation position, the type and the title are obtained by the user through self editing and uploading of mobile terminal software. The unique identifier is set for managing each component by the server side.
The information of codes, models, rated currents, lengths, accuracy and the like in the attributes of each component is uploaded by a manager, wherein the most important graphic characteristics are vector graphics drawn by developers aiming at each component, and the vector graphics are main data for completing graphic drawing. And the server extracts corresponding graphic characteristic data from a database through the graphic identification of the components. The main branch is used for describing the connection mode of the component and other components, and mainly comprises a series connection type and a parallel connection type. In order to realize graph establishment and data intercommunication, a data type is established in back-end and front-end software to describe the power distribution cabinet and each component. The data structure chestModel of the power distribution and the meaning thereof are shown in table 1:
TABLE 1 Power distribution cabinet data structure
Data in the chestModel structure are provided for front-end software by back-end software, and the front-end software starts to execute an addGroup method to draw the power distribution cabinet and the connecting line thereof after receiving the data.
As shown in fig. 9, the addGroup method implements a drawing logic of the cabinet body of the power distribution cabinet. Firstly, whether the direction attribute of the power distribution cabinet is effective or not is judged, and if the direction attribute of the power distribution cabinet is effective, the direction of the power distribution cabinet is drawn according to the corresponding parameter. And then judging whether the power distribution cabinet is a low-voltage incoming line cabinet or not, wherein the transformer is placed between the low-voltage incoming line cabinet and the high-voltage outgoing line cabinet, the basic arrangement is that the high-voltage power distribution cabinets are placed on the same horizontal line, the low-voltage power distribution cabinet is placed on the same horizontal line, a bridge between the high-voltage power distribution cabinet and the low-voltage power distribution cabinet is a high-voltage outgoing line cable, the starting position of the high-voltage outgoing line cable is a high-voltage outgoing line cabinet, and the ending position of the high-voltage outgoing line cable determines the starting position of the low-voltage incoming line cabinet, so that a drawing path of the high-voltage outgoing. And then judging whether the power distribution cabinet is a capacitor cabinet or not, if so, adjusting the arrangement of the capacitor cabinet, namely adjusting the distance between the default capacitor cabinet and the last power distribution cabinet to be 350 pixel points, but because the position occupied by part of low-voltage feeder cabinets (drawer cabinets) on the graph is wider, the length of a horizontal connecting line (bus bridge) on the capacitor cabinet needs to be adjusted, the outgoing line number of the feeder cabinet needs to be stored when the last power distribution cabinet is drawn, and the distance of a bus is adjusted according to the number of the outgoing lines when the bus above the capacitor cabinet is drawn.
And calling an addImage component drawing method to draw components, and continuing to judge whether the current power distribution cabinet is an isolation cabinet, an incoming line cabinet or a metering cabinet after drawing the power distribution cabinet body. Because the bill of materials on the manager is edited according to the current direction, and the current directions of the power distribution cabinets are from bottom to top, the order of the bill of materials is opposite to the order of components in the actual power distribution cabinets, and therefore the power distribution cabinets need to be adjusted after being drawn according to the addImage method, namely the power distribution cabinets need to be rotated by 180 degrees. The title of switch board needs to be generated afterwards, except low-voltage incoming line cabinet and low-voltage feeder cabinet, the title of all the other switch boards all directly shows directly over the switch board region, if the switch board is low-voltage incoming line cabinet, then still need reserve the position of transformer above the switch board, therefore the title needs to be settled in the position that switch board top is inclined to the right or inclined to the left. In the case of a low-voltage feeder cabinet, there are usually multiple branches, so that the total number of branches of the feeder cabinet needs to be obtained first and then a header needs to be placed in the middle.
The addImage method is a core function for drawing components. We also need to define the data structure of the individual components as shown in table 2, where id indicates the type of component and its value corresponds to the number of 56 components in the manager. uuid represents the unique identification of the component, which is generated by back-end software. name is a description label of the component. The position is a value indicating a drawing area of the component, and is usually 1, indicating that the component is drawn on the trunk line, 2 indicating that the component needs to be drawn on the left side of the trunk line, and 3 indicating that the component needs to be drawn on the right side of the trunk line. For example, the live display instrument needs to be drawn on the left side of the trunk line, and therefore the position value of this component of the live display instrument is usually 2. The addImage method execution flow is shown in fig. 10, and execution needs to depend on runtimeData (calculated by back-end software and transmitted to front-end software), and _ this (the front-end software fills data according to an algorithm) and material library imagename. The essence of the addImage method is that the process of intelligently adding component material pictures according to the current running state, reasonably zooming and adjusting the component material pictures and finally displaying the component material pictures on the canvas is realized through a specific algorithm. The rendering properties in this are adjusted (x, y, width, height, name, image) each time an algorithm is executed.
TABLE 2 Components data Structure
In the execution flow of the addImage method, different colors are used for drawing according to the state of the current component, namely green is displayed when the current is on the current line and is less than 80% of the rated current, yellow is displayed when the current is more than 80% and less than 100%, and red is displayed when the current is more than 100%. If there is no current and the corresponding switch board also has no voltage, no delineation is performed. Blue if there is current and the switch cabinet is a reactive compensation cabinet. And next, searching a corresponding material type of the database according to the data state during operation, for example, the disconnecting link has two types of component vector graphs of closing and opening, and if the state (switch or h _ position) transmitted by the back-end software is detected, the software needs to load the component vector graph when the disconnecting link is closed. And next, adjusting the scaling and the placing position of the component vector graph according to the type of the component, wherein x and y in _ this distinguish an abscissa and an ordinate which represent the loading position of the component vector graph, and width and height respectively represent the width and height of the component vector graph. Because the component vector graphics need to be aligned in the middle for splicing, the abscissa x of the component vector graphics needs to perform the operation of alignment in the middle, namely x-width/2 + position width. And finally, loading the component vector graph, adjusting the picture according to the parameter in the _ this, and finally loading the picture on a canvas. The component vector graphics may also be referred to as extracted material. Drawing the materials of 56 components according to the dividing method in fig. 3 and generating a graphics file in the SVG format, wherein the graphics file in the SVG format can ensure extensibility during zooming. The style of the material graphics is shown in fig. 11.
After the drawing of one component is completed, the program can continuously search the next component and draw the next component, and when the last component (basically, a bus) of the power distribution cabinet is searched, the component drawing process of the power distribution cabinet is completed. The drawing sheet is completed as shown in fig. 12.
According to the embodiment, the manager installed on the power distribution cabinet is used for editing and storing the bill of materials of the power distribution equipment in the corresponding power distribution cabinet, and a user can compare the contents in the bill of materials with the real objects in person to see whether the contents conform to the real objects, so that errors can be reduced to the greatest extent. The user does not need to change after editing once.
The server side automatically acquires the list data from the manager without manual intervention and then automatically draws the whole electrical diagram, so that human factors are reduced to the maximum extent.
