Description

Technical Field

[0001] This invention belongs to the field of electrical design, and in particular relates to a method and device for automatically generating power supply diagrams for industrial control cabinets. Background Technology

[0002] With the continuous advancement of automation technology and the rapid development of new information technology, the scale of enterprise automation control systems has expanded dramatically. Correspondingly, the scale of system integration has also increased significantly. The assembly design drawings required for system hardware integration mainly include layout diagrams and power supply diagrams, with power supply diagrams being particularly abundant. For instrumentation and control systems such as PLCs, DCSs, and SISs, the original power supply design required manual identification of the model, quantity, port, and location number of each power supply device, distinguishing between different power supply categories (for field equipment or internal system components), manually compiling power supply terminal blocks, and repeatedly copying and pasting to manually number and connect various power supply devices. Relying on purely manual design is far from meeting project schedule requirements, both in terms of efficiency and quality.

[0003] Existing technical solutions and their drawbacks: Currently, there are some design software programs in the industry, such as IAtools from Beijing Wisdom Tusi Software Co., Ltd. However, it focuses on the early stages of automatic control engineering design, such as instrument indexes, DCS / SIS IO lists, alarm interlock lists, cable lists, instrument hook-ups, installation diagram indexes, instrument bills of materials (BOM), calculations for control valves, throttling devices, and thermometer sleeves, etc. Another example is EPLAN software, which is mainly based on certain electrical principles and focuses on electrical design. Moreover, this software requires a large initial investment and has high maintenance costs in the later stages. Summary of the Invention

[0004] The technical objective of this invention is to provide a method and apparatus for automatically generating power supply diagrams for industrial control cabinets, so as to solve the technical problems of complex and inefficient power supply in the hardware integration and assembly of industrial control cabinets.

[0005] To solve the above problems, the technical solution of the present invention is as follows:

[0006] A method for automatically generating power supply diagrams for industrial control cabinets, using a computer-configured power supply diagram generation system to automatically generate power supply diagrams for industrial control cabinets, including AC power supply design diagrams and DC power supply design diagrams, comprising the following steps:

[0007] S1: Start the power supply diagram generation system, and then determine the type of power supply diagram for the industrial control cabinet to be constructed. If it is an AC power supply design diagram, proceed to step S2; if it is a DC power supply design diagram, proceed to step S3.

[0008] S2: Obtain the component information of the input power supply, main circuit breaker, and branch circuit breakers for constructing the AC power supply design diagram, then connect the components, and output the AC power supply design diagram, AC component layout diagram, and AC component list based on the power supply, main circuit breaker, and branch circuit breakers. If no DC power supply design diagram is constructed, proceed to step S3; otherwise, put the power supply diagram generation system into standby mode.

[0009] S3: Obtain the component information of the power supply unit, load element, and DC power supply terminal block for constructing the DC power supply design diagram, then connect the components, and output the DC power supply design diagram, DC component layout diagram, and DC component list constructed based on the power supply unit, load element, and power supply terminal block. If no AC power supply design diagram is constructed, proceed to step S2; otherwise, put the power supply diagram generation system into standby mode.

[0010] Specifically, step S2 is as follows:

[0011] S21: Obtain the component information of the input power supply, including the number of power input channels and the type of input power supply. The type of input power supply includes uninterruptible power supply or power frequency AC power supply.

[0012] Obtain the component information of the main circuit breaker. The number of main circuit breakers is set to correspond to the number of power input circuits. The component information of the main circuit breaker includes the serial number, rated current value, current transformer change and copper busbar specifications.

[0013] Obtain the component information of the branch circuit breakers. The number of branch circuit breakers should correspond to the copper busbar specifications of the total circuit breakers. The component information of the branch circuit breakers includes the serial number, rated current value, and load name.

[0014] S22: Based on the component information of the input power supply, main circuit breaker and branch circuit breaker, combined with the power supply logic configured in the power supply diagram generation system, construct the AC power supply design diagram, AC component layout diagram and AC component list.

[0015] More preferably, the step between step S21 and step S22 further includes the following steps:

[0016] The component information of the AC power supply terminal block is obtained and added to the AC power supply design drawing, AC component layout drawing and AC component list by the power supply diagram generation system, and the AC power supply terminal block is set between the main circuit breaker and the corresponding branch circuit breaker.

[0017] The component information of the AC power supply terminal block includes the model and the number of terminal groups. The selection of the AC power supply terminal block model and the number of terminal groups is subject to the component information of the circuit breaker.

[0018] Specifically, in step S22, the power supply logic includes

[0019] If the rated current of the branch circuit breaker is greater than or equal to 25A, the branch circuit breaker is connected to one contact on the copper busbar of the corresponding main circuit breaker.

[0020] If the rated current of the branch circuit breaker is less than 25A, then 12 branch circuit breakers with rated current less than 25A are grouped together and connected to one contact on the copper busbar of the corresponding main circuit breaker.

[0021] If the number of a set of circuit breakers is not set, it will be automatically named by the power supply diagram generation system.

[0022] Specifically, step S3 is as follows:

[0024] Obtain the power supply type of the power supply unit, including internal power supply and external power supply.

[0025] S32: Obtain the component information of the DC power supply terminal block and add the DC power supply terminal block based on the installation location of the load component and the power supply type of the power supply unit.

[0026] S33: Add load components in batches and connect them to the DC power supply terminal block in the DC power supply design diagram.

[0027] S34: Based on the component information of the load element, DC power supply terminal block and power supply type of the power supply unit, and combined with the power supply logic configured in the power supply diagram generation system, construct the DC power supply design diagram, DC component layout diagram and DC component list.

[0028] Specifically, based on the model and quantity of load components, they are grouped and automatically numbered by the power supply diagram generation system.

Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0056] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a method and apparatus for automatically generating power supply diagrams for industrial control cabinets based on the present invention. The advantages and features of the present invention will become clearer from the following description and claims.

[0057] Example 1

[0058] See Figure 1This embodiment provides a method for automatically generating power supply diagrams for industrial control cabinets. It utilizes a power supply diagram generation system configured on a computer to automatically generate power supply diagrams for industrial control cabinets. The power supply diagrams for industrial control cabinets include AC power supply design diagrams and DC power supply design diagrams, and include the following steps:

[0059] First, in step S1, the power supply diagram generation system is started. Since the industrial control cabinet power supply diagram design involves both AC and DC power supply design, the type of power supply diagram to be constructed is determined based on requirements. If it is an AC power supply design diagram, proceed to step S2; if it is a DC power supply design diagram, proceed to step S3. The above steps are only to distinguish between AC and DC power supply designs and do not represent the actual order of implementation.

[0060] See Figures 2 to 5 The following section, step S2, provides a detailed explanation of how to construct the AC power supply design diagram.

[0061] In step S21, the component information of the power supply is input into the system, including the number of power input channels and the type of power supply. The number of power input channels can be one, two, or three. The type of power supply includes uninterruptible power supply (UPS) or mains AC power (AC), or other types. See also Figure 2 As can be seen, in this embodiment, three inputs are used, two of which are uninterruptible power supplies and one is a power frequency AC power supply.

[0062] Input the component information of the main circuit breaker. The number of main circuit breakers corresponds to the number of power input circuits; in this embodiment, there are three main circuit breakers. The component information of the main circuit breaker includes its own serial number, the rated current value it can pass, the current transformer change, and its own copper busbar specifications.

[0063] You also need to enter the component information for the branch circuit breakers. The number of branch circuit breakers should correspond to the copper busbar specifications of the main circuit breakers. The component information for the branch circuit breakers includes their serial number, the rated current they can handle, and the name of the loads they are subsequently connected to. See details. Figure 3 This refers to the component information of the input power supply, main circuit breaker, and branch circuit breaker for a power input circuit, i.e., the input component information.

[0064] Preferably, depending on the requirements, the branch circuit breaker can be required to be connected via a terminal block, and several AC power supply terminal blocks can be set in batches. The component information of the AC power supply terminal block is input, and the AC power supply terminal block is set between the main circuit breaker and the corresponding branch circuit breaker. The component information of the AC power supply terminal block includes the model and the number of terminal groups. The selection of the AC power supply terminal block model and the number of terminal groups is limited by the component information of the branch circuit breaker.

[0065] Next, in step S22, the power supply logic configured in the power supply diagram generation system is combined with the component information of the input power supply, main circuit breaker and branch circuit breaker to construct CAD drawings, which include AC power supply design drawings, AC component layout drawings and AC component lists.

[0066] Specifically, the power supply logic is as follows: the number of branch circuits on each copper busbar of the main circuit breaker is designed as follows: each group of circuit breakers (installed on the same busbar) is grouped by default. If the current value of a branch circuit breaker is greater than or equal to 25A, a single power supply wire is used for each contact on the copper busbar; for other capacities, 12 branch circuit breakers are grouped by default. On the same copper busbar, the branch circuit breakers in this group are either all numbered or none are numbered. When the branch circuit breakers in this group are not numbered, the power supply diagram generation system will automatically name the branch circuit breakers in this group according to the built-in naming rules. For example, the first 12 branch circuit breakers of the first power supply can be named AC1101~AC1112.

[0067] Circuit breaker terminal adapter (terminal block name) and number of terminal groups (number of terminals): Terminal block names can be automatically added (AC power supply terminal blocks (e.g., TB11 / TB12)). Terminal model selection rules: Select according to the brand and current value of the circuit breaker. If the rated current is ≤10A, use 2.5 ohms; if 10A < rated current ≤20A, use 4 ohms; if 20A < rated current ≤32A, use 6 ohms; if 32A < rated current ≤50A, use 10 ohms; if 50A < rated current ≤63A, use 16 ohms; if 63A < rated current ≤100A, use 35 ohms; if 100A < rated current, AC terminal adapters are not supported.

[0068] See Figures 6 to 13 Step S3 provides a detailed explanation of how to construct the AC power supply design diagram. Specifically, step S3 involves...

[0069] See Figure 6 and Figure 7 In step S31, the component information of the load elements is input into this embodiment, including model, quantity, and installation location. This includes external load elements and system load elements. External load elements include safety barriers, relays, etc., while system load elements include terminal blocks, racks, and modules, etc. The power supply type of the power supply unit is input, including internal power supply (within the system) and external power supply (field side).

[0070] Furthermore, refer to Figure 9In step S32, DC power supply terminal blocks are added in batches according to the project's engineering identification requirements. These engineering identification requirements are the naming and symbol codes set for each component according to certain industry (or enterprise) standards, or other special naming requirements agreed upon in the project's technical agreement. For example, the DC power supply terminal blocks are named TBmn, where m corresponds to the auxiliary DC power supply in a single cabinet, with values ​​from 5 to 8. The first pair of DC power supply terminal blocks in the same cabinet is TB5, the second pair is TB6, and so on. n starts from 1, sequentially 1, 2, 3…, where odd n represents positive and even n represents negative, such as TB51 (DC24V+) and TB52 (DC24V-). Specifically, the component information of the DC power supply terminal blocks is input, and appropriate DC power supply terminal blocks are set according to the installation location of the load components (front or back of the cabinet) and the power supply category of the power supply unit based on the engineering identification requirements. For example, DC power supply terminal blocks within the system (TB51, TB52) and DC power supply terminal blocks on the field side (TB61, TB62) will automatically appear in pairs. The model of the DC power supply terminal can be set in batches, and a certain amount of spare capacity can be set.

[0071] Then, see Figure 8 , Figures 10 to 12 In step S33, in this embodiment, according to the industry's component naming rules, identical components are grouped into groups of 8 or 16 (mainly depending on the number of channels in the system module). Based on the model and quantity of the load components, they are grouped and automatically numbered by the power supply diagram generation system. Examples include safety barriers (SB0101~SB0116), relays (RY0101~RY0108), isolators (SI0201~SI0208), relay terminal blocks (TPA01~TPA06), etc. The numbering order can be adjusted up or down. The corresponding DC power supply terminal block is selected for the load component. Once one group is selected, subsequent groups are automatically added to the DC power supply terminal block until another DC power supply terminal block is selected, finally connecting the load component to the DC power supply terminal.

[0072] Finally, see Figure 13 In step S34, based on the component information of the load element, the DC power supply terminal block, and the power supply category of the power supply unit, and combined with the power supply logic configured in the power supply diagram generation system, a DC power supply design diagram, a DC component layout diagram, and a DC component list are constructed.
