[0034] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0035] Embodiment 1:

[0036] In order to realize the efficient and accurate generation of nuclear safety-grade DCS cabinet assembly drawings and cable lists, this embodiment proposes a method for generating nuclear safety-grade DCS cabinet assembly drawings and cable lists, which realizes the automatic and efficient generation of nuclear safety-grade DCS cabinet assembly drawings and cable lists, reduces manual workload, improves design efficiency, reduces human errors, and improves accuracy.

[0037] like Figure 1 As shown, the method proposed in this embodiment specifically includes the following steps:

[0038] Step 100, extracting basic information of equipment components and their connection relationship information from the wiring schematic diagram, and extracting assembly areas of equipment components and their assembly location number information from the layout diagram.

[0039] The assembly area includes the system architecture diagram, equipment room layout diagram, room wiring bracket layout diagram and system interface diagram. The equipment components and their connection relationship information, as well as the equipment component assembly area and its assembly location number (assembly position number) information are extracted for subsequent logical processing.

[0040] Step 200, combining preset rules, performing rule matching and classification processing on the extracted information, and reconstructing the relationship between the information.

[0041] The preset rules include sequence rules, matching rules and short-circuit rules. The sequence rules refer to sorting the extracted information according to the equipment, signal type, cabinet number, drawing page number and other factors; the matching rules refer to matching the wiring information at both ends of the extracted information according to the template. The typical matching rule is that the signal names at both ends are the same or the signal name and the serial number are combined in a regular manner; the short-circuit rule means that the short-circuit piece of the terminal block cannot be continuously short-circuited beyond the upper limit.

[0042] like Figure 2 As shown, the extracted information is processed in combination with preset rules, specifically including:

[0043] Step 201, in combination with preset rules, rule matching and classification are performed on the information extracted from the wiring schematic diagram, and a cable list is reconstructed, including the list of optical fibers / wires in the cabinet, optical fibers / wires between cabinets, optical cables / electric cables between cabinets, and terminated optical cables / electric cables, etc. Specifically, it includes:

[0044] First, judgment and classification are performed based on the extracted connection relationship information: determine whether the connection relationship is an in-cabinet connection. If it is an in-cabinet connection, it is divided into in-cabinet optical fiber (yes) and in-cabinet wire (no) according to whether it is connected through a communication module.

[0045] If the connection is not within the cabinet, it is also determined whether it is connected through the communication module, which is divided into optical fiber / optical cable (yes) and wire / cable (no). Then it is determined whether the cabinets at the starting end and the end end are connected in parallel and the distance is less than or equal to the limit (for example, 5 cabinets). If so, they are inter-cabinet optical fiber and inter-cabinet wire respectively; otherwise, they are optical cable and cable respectively. For optical cables and cables, it is further distinguished whether they are going outside the system. If so, they are terminated optical cables and terminated cables respectively. Optical cables going inside the system are inter-cabinet optical cables, and cables going inside the system are inter-cabinet cables. Inter-cabinet cables can be divided into power cables, measurement cables, control cables, and grounding cables according to their purpose, as shown below. Figure 3 The example of the subsystem connection classification diagram is shown. Then, the processed information is matched with the corresponding preset rules to reconstruct the cable inventory.

[0046] Step 202: Based on the system architecture diagram, equipment room layout diagram, room wiring bracket layout diagram, and system interface diagram of the assembly area, network connection information, cabinet information, laying path information, and internal and external subsystem lists are extracted and sorted. The information extracted from the layout diagram is matched with the corresponding preset rules, and the connection relationship is classified and sorted according to the equipment components and port numbers, and the starting point and end point are matched to obtain the connection relationship. And the connection relationship list between the equipment components is reconstructed in units of equipment components.

[0047] Step 300, calling a pre-built simulation verification method to review and verify the reconstructed information: including electrical safety check, layout position interference check and wiring rationality check.

[0048] The construction method of the simulation verification method specifically includes:

[0049] Obtain basic property information of various equipment components from the database, including electrical properties, dimensional properties, etc.;

[0050] According to the basic attribute information of equipment components, the electrical safety simulation verification method, layout interference simulation verification method, and wiring rationality simulation verification method are constructed. The electrical safety simulation verification method includes the selection of equipment components and whether the positive and negative poles of the power supply are connected in reverse. The layout interference simulation verification method includes the size of equipment components and whether interference problems will occur after simulation installation. The wiring rationality simulation verification method includes the inspection of the same wiring point cannot connect more than two wires, and the short-circuit piece cannot be continuously short-circuited beyond a certain upper limit.

[0051] Step 400, based on the information that has passed the review and verification, an assembly drawing and a cable list are generated and driven to form a file output.

[0052] In step 400, the information that has been verified and checked is filled in according to the preset template format to realize the generation of assembly drawings, cable lists, etc. The generated assembly drawings and cable lists are driven by Excel drivers, Eplan drivers, etc. to form the final drawings and cable lists. The selection of different drive methods is related to the generated file format. For example, the assembly drawings can be in Excel format or annotation information can be marked on the assembly drawings generated by Eplan software, and the cable lists can be in Excel format.

[0053] Furthermore, after the assembly drawing and the cable list are automatically generated, manual modification or human error modification may still occur. Therefore, in order to avoid this situation, the method proposed in this embodiment further includes:

[0054] Utilizing the assembly drawing and cable inventory information stored in the automatic generation process, the inspection function is used to inspect the assembly drawing and cable inventory to be inspected and generate an inspection report, which is then driven by the FileStream driver to generate a file output. The inspection report can be in the format of a txt file.

[0055] The method proposed in this embodiment realizes the automatic generation of nuclear safety-grade DCS cabinet assembly drawings and cable lists, and can also check their correctness, which can effectively improve the automation level of the design process, save labor costs, and reduce human errors.

[0056] Based on the same technical concept as above, this embodiment also proposes a nuclear safety grade DCS cabinet assembly drawing and cable list generation system, such as Figure 4 As shown, the system proposed in this embodiment specifically includes:

[0064] Furthermore, the rule module also includes: a sequence rule unit, a matching rule unit and a short-circuit rule unit. Among them, the sequence rule unit presets a sequence rule, which means that the extracted information is sorted according to the elements such as the device to which it belongs, the signal type, the cabinet number, the drawing page number, etc.; the matching rule unit presets a matching rule, which means that the extracted information is matched with the wiring information at both ends according to the template, and the typical matching rule is that the signal names at both ends are the same or the signal name and the serial number are combined in a regular manner; the short-circuit rule unit presets a short-circuit rule, which means that the short-circuit piece of the terminal block cannot be continuously short-circuited beyond the upper limit.

[0065] Furthermore, the simulation module includes an electrical safety simulation unit, a layout interference simulation unit, and a wiring rationality simulation unit. The electrical safety simulation unit constructs an electrical safety inspection strategy based on the basic attribute information of the equipment components, including the selection of equipment components, whether the positive and negative poles of the power supply are connected in reverse, etc.; the layout interference simulation unit constructs a layout position interference inspection strategy based on the basic attribute information of the equipment components, including the inspection of the equipment component size, whether interference will occur after the simulation installation, etc.; the wiring rationality simulation unit constructs a wiring rationality inspection strategy based on the basic attribute information of the equipment components, including the inspection that the same wiring position cannot be connected to more than two wires, and the short-circuit piece cannot be continuously short-circuited beyond a certain upper limit.

[0090] Extract templates (i.e. format templates in the template library), such as Figure 6-8 As shown in the figure, the user has configured the inter-cabinet wire inventory template, inter-cabinet cable inventory template, and terminated cable inventory template.

[0091] According to the header format set by the user, the extracted information is matched with the corresponding preset rules, and the following is obtained after the information is reconstructed: Figure 9-11 The shown inventory of inter-cabinet wires, inter-cabinet cables and terminated cables.

After the inspection is completed, an inspection report is formed, and then the output driver module outputs the report.

[0099] Embodiment 3:

[0100] This embodiment takes the safety-level DCS design of a typical nuclear power plant as an example and designs the electrical principle design drawings of the DCS cabinet based on the Eplan electrical software. Fig.13 The electrical schematic diagram shown is processed in accordance with the processing logic of the method and system proposed in the above-mentioned embodiment 1.

[0101] First, from Fig.13 Read the equipment components and connection relationships involved in the electrical schematic diagram shown. The equipment components include: GS501, GX501, GF701, GF705. The connection relationship list is shown in Table 8.

[0102] Table 8 Connection relationship list

[0103]

[0104]

[0105] For common drawing software, the order and connection relationship of the device components read before sorting are generally related to the placement order and connection order during drawing.

[0106] from Fig.14 The layout area information and assembly location number of the equipment components are read from the layout diagram shown in Table 9 to obtain the layout diagram extraction information list shown in Table 9.

[0107] Table 9 List of information extracted from layout drawing

[0108] Serial number Equipment components Layout Area Assembly location number 1 GS501 Front view-2 NT103 2 GF701 Rear view-2 NT211 3 GF705 Rear view-2 NT209 4 GX501 Rear view-2 NT208

[0109] The layout areas include front view / rear view / AA view / BB view-X, where X is 1 to 11, indicating that each 4U is a unit starting from the top 44U (usually each mounting plate or chassis is a unit, and when spanning two areas, the upper area shall prevail).

[0110] Get the attribute information of equipment components from the database template: GS501: C65H-DC / 2P C32A; GF701: UK10N; GF705: UK5N; GX501: MY4ZN-D2 DC24(S).

[0111] At the same time, the template is extracted. As shown in Table 10, the user configures the assembly drawing template:

[0112] Table 10 Assembly drawing template

[0113]

[0114] The extracted information is matched with the template according to the header format, and after information reconstruction, the assembly drawing example shown in Table 11 is obtained.

[0115] Table 11 Assembly drawing example

[0116]

[0117] The rows with the same shorting group value are shorted together, which does not appear in this example.

[0118] Since one port of a terminal can connect two equipment components in two directions, the assembly drawing template of the terminal is different from that of ordinary equipment components. An example is shown in Table 12.

[0119] Table 12 Terminal assembly drawing template

[0120]

[0121] Another example of a template represented in graphical form is shown in Table 13.

[0122] Table 13 Graphical assembly drawing template

[0123]

[0124] Among them, the local port 1 shows a form with two crimped wires.

[0125] The graphical terminal template is shown in Table 14.

[0126] Table 14 Graphical assembly drawing template for terminals

[0127]

[0128] In the figure, the short-circuit group is expressed in graphical form.

[0129] The extracted information is matched with the corresponding preset rules, the connection relationship is classified and sorted according to the device component and port number, and the starting point and the end point are matched to obtain the connection relationship.

[0132] Then, the connection relationship list shown in Table 16 is reconstructed based on the device components.

[0134]

[0135]

[0136] The reconstructed information is reviewed and verified, including: electrical safety inspection, checking the positive and negative poles of the wiring of each equipment component and the rationality of the wiring according to the electrical safety inspection table (Table 17).

[0139] After checking, the positive and negative wiring of each device component is correct and the cable color is correct.

[0140] Table 18 Equipment contact wiring table

[0141]

[0142] Upon inspection, each equipment component's single wiring point was connected to only one wire, as shown in Table 18, which meets the wiring requirement that a wiring point can be connected to no more than two wires of the same diameter.

[0143] Arrange interference checks, check the relationship between the equipment component dimensions and their coordinates, and determine whether there is any impact.

[0144] Table 19 Equipment component location and size information

[0145] Serial number Device Name Dimensions (width x height x depth) mm coordinate 1 GS501 36×84×73.5 (221.885,1744) 2 GF701 20.4×42.5×47.3 (528.035,1733.55) 3 GF705 20.4×42.5×47.3 (462.035,1733.55) 4 GX501 29.5×72×46 (421.530,1749.721)

[0146] The coordinates are the relative coordinates of the upper left corner of the device component with the 0U height point at the left edge of the view as the coordinate origin. Interference is calculated and the overall size of the device components arranged in batches such as terminal blocks is taken.

[0147] According to the equipment component position and size information shown in Table 19, taking the interference calculation of adjacent GX501 and GF705 as an example, the horizontal coordinate of GX501 plus its width and a fixing width (9.5mm) should be smaller than the horizontal coordinate of GF705.

[0148] Through calculation, we get: 421.530+29.5+9.5=460.53, so 460.53 is less than 462.035.
