[0016] The original DCS cabinet is scanned using 3D imaging recognition. Based on the first identifier on the hardware devices in the original DCS cabinet, the original layout diagram of the hardware devices in the original DCS cabinet can be obtained. Furthermore, based on the original layout diagram, the database information of the original DCS cabinet, and the target functions of the upgraded DCS cabinet, a table is generated showing the cable connection locations of the original DCS cabinet and the terminal connection locations of the hardware devices in the upgraded DCS cabinet. This facilitates the connection of cables in the original DCS cabinet to the corresponding terminals of the hardware devices in the upgraded DCS cabinet, thereby ensuring the cable connection is correct. While accurately restoring the original DCS cabinet, a significant amount of on-site location verification work is eliminated. Furthermore, by fixing the original DCS cabinet's cables and then disassembling the original DCS cabinet's hardware terminals and cables, the tangling of the cables after disassembly can be avoided, thus ensuring quick wiring between the original DCS cabinet's cables and the hardware terminals of the upgraded DCS cabinet. Therefore, by generating a comparison table of the original DCS cabinet's cable wiring positions and the upgraded DCS cabinet's hardware terminal wiring positions, and by fixing the original DCS cabinet's cables before disassembly, the difficulty of DCS modification is effectively reduced, ensuring high-efficiency and high-precision DCS upgrades.

[0017] Additional aspects and advantages of this disclosure will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this disclosure. Attached Figure Description

[0018] The above and / or additional aspects and advantages of this disclosure will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which: Figure 1 This is a flowchart illustrating a DCS retrofitting method based on three-dimensional imaging recognition proposed in an embodiment of this disclosure; Figure 2 This is an original layout diagram of the hardware equipment for modifying a DCS cabinet according to an embodiment of this disclosure; Figure 3 This is a schematic diagram of the structure of a fixed module proposed in an embodiment of this disclosure; Figure 4 This is a schematic diagram of the structure of the first identifier proposed in an embodiment of this disclosure; Figure 5 This is a schematic diagram of the structure of an imaging recognition device according to an embodiment of this disclosure; As shown in the figure: 1. Imaging recognition device, 2. Adjustment bracket, 3. Fixing module. Detailed Implementation

[0019] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] like Figure 1 As shown, this disclosure proposes a DCS (Distributed Control System) transformation method based on three-dimensional imaging recognition, including: S1: Set the first identifier on the hardware equipment of the original DCS cabinet; S2: Scan the original DCS cabinet through 3D imaging recognition, and obtain the original layout diagram of the hardware equipment in the original DCS cabinet based on the first identifier on the hardware equipment in the original DCS cabinet. S3: Based on the original layout diagram of the hardware equipment of the original DCS cabinet, the database information of the original DCS cabinet, and the target function of the modified DCS cabinet, generate a comparison table of the cable connection positions of the original DCS cabinet and the hardware equipment terminal connection positions of the modified DCS cabinet. S4: Secure the cables in the original DCS cabinet and disconnect the hardware terminals and cables in the original DCS cabinet; S5: Replace the original DCS cabinet with a modified DCS cabinet, and connect the cables of the original DCS cabinet to the hardware device terminals of the modified DCS cabinet according to the cable connection position of the original DCS cabinet and the hardware device terminal connection position of the modified DCS cabinet.

[0021] Understandably, by scanning the original DCS cabinet using 3D imaging recognition and based on the first identifier on the hardware devices in the original DCS cabinet, the original layout diagram of the hardware devices in the original DCS cabinet can be obtained. Furthermore, based on the original layout diagram of the hardware devices in the original DCS cabinet, the database information of the original DCS cabinet, and the target functions of the modified DCS cabinet, a comparison table of the cable connection positions of the original DCS cabinet and the hardware device terminal connection positions of the modified DCS cabinet can be generated. This facilitates the connection of the cables in the original DCS cabinet to the corresponding hardware device terminals in the modified DCS cabinet according to the comparison table. This ensures accurate cable restoration while saving a lot of on-site point verification work. Moreover, by fixing the cables in the original DCS cabinet and then disassembling the hardware device terminals and cables, the tangling of the cables after disassembly can be avoided, thus ensuring quick wiring between the cables in the original DCS cabinet and the hardware device terminals in the modified DCS cabinet.

[0022] Therefore, by generating a comparison table of the original DCS cabinet cable connection positions and the terminal connection positions of the modified DCS cabinet hardware equipment, and by fixing the original DCS cabinet cables before disassembly, the difficulty of DCS modification was effectively reduced, ensuring high-efficiency and high-precision DCS modification and upgrade.

[0023] It should be noted that there are two traditional methods for upgrading and transforming DCS: Method 1: Directly remove the cables from the original DCS cabinet, then replace it with the modified DCS cabinet, and finally connect the cables from the original DCS cabinet to the hardware terminals of the modified DCS cabinet. Temporary markers need to be set up at each stage of cable removal, and formal markers need to be made during the restoration stage, along with a point-to-point verification between the hardware terminals of the modified DCS cabinet and the cables from the original DCS cabinet. The main problems are: (1) Cables of various types of cards were not distinguished after removal, making restoration difficult; (2) Temporary markers and formal markers for all cables increase the workload of construction personnel; (3) DCS engineers need to be stationed on-site for extended periods to verify the cabinet layout and provide the latest version of the DCS cabinet equipment layout diagram from the database.

[0024] Method 2: Retain the original DCS cabinet, install and modify the DCS cabinet in the existing space, and use the original DCS cabinet as an intermediate terminal box for transfer. The main problems are: (1) Although it improves the accuracy and timeliness, it increases the cost of materials; (2) Most existing power plants cannot provide installation locations for new and modified DCS cabinets nearby, so it cannot be widely implemented.

[0025] In response to the above-mentioned issues, the DCS retrofit method in this embodiment, based on Method 1, utilizes three-dimensional imaging recognition technology. By generating a comparison table of the cable connection positions of the original DCS cabinet and the hardware equipment terminal connection positions of the retrofitted DCS cabinet, and by fixing the cables of the original DCS cabinet before disassembly, the above-mentioned problems can be effectively avoided, while taking into account the requirements of low cost, high efficiency, and high accuracy.

[0026] The purpose of the method in this embodiment is to complete the DCS transformation and upgrade work in a low-cost, high-efficiency, and high-precision manner, which greatly facilitates the work of on-site construction personnel and DCS technicians, and also provides guidance and experience for subsequent large-scale DCS or similar project upgrades and transformations.

[0027] Among them, 3D imaging recognition uses 3D imaging technology to generate a 3D image of the original DCS cabinet. Furthermore, by using the first identifier in the 3D image, the original layout diagram of the hardware equipment of the original DCS cabinet can be quickly obtained. This facilitates the generation of a comparison table of cable connection positions of the original DCS cabinet and terminal connection positions of the hardware equipment of the modified DCS cabinet based on the original layout diagram of the hardware equipment of the original DCS cabinet.

[0028] For example, for the hardware devices in the original DCS cabinet, each card is labeled with AI, AO, RTD, DO, DI, etc., and distinguished by color markings such as red, blue, green, yellow, and purple. Moreover, the number of cards within each type is distinguished from 1 to 100, and controllers and power supplies can be distinguished by white and black, and their quantities are distinguished by 1 and 2.

[0029] In some embodiments, the method further includes: The original layout diagram of the hardware equipment of the original DCS cabinet, the database information of the original DCS cabinet, and the target functions of the DCS cabinet to be upgraded are used to generate the original layout diagram of the hardware equipment of the upgraded DCS cabinet. Based on the original layout diagram of the hardware equipment in the original DCS cabinet and the original layout diagram of the hardware equipment in the modified DCS cabinet, a comparison table of the cable connection positions of the original DCS cabinet and the terminal connection positions of the hardware equipment in the modified DCS cabinet is generated.

[0030] Understandably, based on the original hardware layout diagram of the original DCS cabinet, the database information of the original DCS cabinet, and the target functions of the modified DCS cabinet, an original hardware layout diagram of the modified DCS cabinet is generated. Then, based on the original and modified DCS cabinet hardware layout diagrams, a comparison table is generated showing the cable connection locations of the original DCS cabinet and the terminal connection locations of the modified DCS cabinet. This facilitates the operators in connecting the cables of the original DCS cabinet to the corresponding terminals of the modified DCS cabinet, thus ensuring accurate cable restoration while saving a significant amount of on-site location verification work.

[0031] It should be noted that the process of generating the original layout diagram of the hardware equipment in the modified DCS cabinet, as well as the comparison table of the cable connection positions of the original DCS cabinet and the hardware equipment terminal connection positions of the modified DCS cabinet, does not need to be performed on-site. The operators can remotely obtain the original layout diagram of the hardware equipment in the original DCS cabinet by scanning the original DCS cabinet through 3D imaging recognition. Before replacing the DCS cabinet, the comparison table of the cable connection positions of the original DCS cabinet and the hardware equipment terminal connection positions of the modified DCS cabinet is generated, thereby saving a lot of on-site point verification work, improving the efficiency of DCS transformation, and reducing labor costs.

[0032] For example, such as Figure 2 The diagram shown is the original layout of the hardware equipment in a modified DCS cabinet.

[0033] In some embodiments, the method further includes: When generating the original layout diagram of the hardware equipment for the modified DCS cabinet, the hardware equipment for the modified DCS cabinet is placed in the same position as the original DCS cabinet.

[0034] Understandably, by placing the hardware equipment for the upgraded DCS cabinet in the same locations as the original DCS cabinet, changes in cable connection positions can be reduced. This not only lowers the error rate and improves wiring accuracy but also shortens the wiring distance and improves wiring efficiency.

[0035] It should be noted that by placing the hardware equipment for the modified DCS cabinet in the same location as the original DCS cabinet, the wiring positions of the cables can be kept unchanged to the greatest extent possible, greatly reducing errors during the restoration of wiring.

[0036] In addition, for hardware devices with the same function but different types, the number of channels in a single module may vary. Reasonable adjustments can be made based on this to reduce changes in cable points.

[0037] like Figure 3 As shown, in some embodiments, the method further includes: Multiple cables connecting the same hardware device in the original DCS cabinet are grouped into the same cable group. Each group of cables is fixed by a fixing module 3, and a second identifier corresponding to the first identifier on the hardware device is set on the fixing module 3; Disassemble the hardware terminals and cables of the original DCS cabinet; Replace the original DCS cabinet with a modified DCS cabinet, and connect the cables of the original DCS cabinet and the hardware equipment terminals of the modified DCS cabinet according to the cable connection position of the original DCS cabinet and the hardware equipment terminal connection position of the modified DCS cabinet, as well as the second label. Remove the fixing modules 3 from each group of cables.

[0038] Understandably, each group of cables is fixed by a fixing module 3, and a second identifier corresponding to the first identifier on the hardware device is set on the fixing module 3, so as to facilitate the corresponding connection between the cables of the original DCS cabinet and the hardware device terminals of the modified DCS cabinet, and achieve high-efficiency and high-accuracy wiring restoration.

[0039] It should be noted that the fixing module 3 is used to fix the corresponding cables of the hardware equipment, so that when the original DCS cabinet is replaced with a modified DCS cabinet, the relative position of the cables remains unchanged, thereby achieving fast and accurate wiring restoration.

[0040] The second identifier can be the same as the first identifier, specifically in terms of color, quantity, code, etc.

[0041] In some embodiments, the method further includes: The fixed module 3 is configured as a telescopic structure. Before replacing the original DCS cabinet with the modified DCS cabinet, the retraction action of the fixed module 3 is used to move the cable away from the original DCS cabinet. After replacing the original DCS cabinet with the modified DCS cabinet, the extension action of the fixed module 3 is used to move the cable closer to the modified DCS cabinet.

[0042] It is understandable that setting the fixed module 3 as a telescopic structure and using the telescopic nature of the fixed module 3 to allow cables to avoid collisions when replacing the DCS cabinet can not only protect the cables and prevent damage from impacts, but also enable the rapid replacement of the DCS cabinet and improve the efficiency of DCS transformation and upgrade.

[0043] The specific type of the fixing module 3 can be set according to actual needs and there are no restrictions. For example, the fixing module 3 can be a snap-on clamping structure. The same fixing module 3 can clamp multiple cables of the same group at the same time. In addition, the fixing module 3 can be telescopically arranged using a telescopic rod.

[0044] In some embodiments, the method further includes: Set the first identifier on the first label and affix the first label to the hardware equipment in the original DCS cabinet; Set the second identifier on the second label and affix the second label to the fixed module 3.

[0045] It is understandable that the first identifier is set on the first label and the first label is affixed to the original DCS cabinet hardware, which facilitates the setting of the first identifier on the original DCS cabinet hardware and also makes it easy to remove.

[0046] The second identifier is placed on the second label and the second label is pasted on the fixing module 3, which facilitates the setting of the second identifier on the fixing module 3 and also makes it easy to remove.

[0047] In some embodiments, the method further includes: A first identifier is set on the hardware devices in the original DCS cabinet based on the type and quantity information of the hardware devices in the original DCS cabinet.

[0048] Understandably, by setting a first identifier on the hardware devices in the original DCS cabinet based on the type and quantity information of the hardware devices in the original DCS cabinet, the type and channel location of the corresponding hardware devices can be quickly determined based on the first identifier, thereby facilitating efficient and accurate disconnection and reconnection.

[0049] For example, based on the type information of the hardware devices in the original DCS cabinet, the first identifier can be set to AI, AO, RTD, DO, DI, etc., and based on the quantity information of the hardware devices in the original DCS cabinet, the first identifier can be set to 1, 2, 3, 4, etc.

[0050] Specifically, such as Figure 4 As shown, the hardware devices are sequentially configured as AO1-AOn, AI1-AIn, DI1-DIn, etc.

[0051] In some embodiments, the method further includes: After disconnecting the hardware terminals and cables of the original DCS cabinet, a protective cover is placed over the cables. Before connecting the cables of the original DCS cabinet to the corresponding hardware terminals of the modified DCS cabinet, the protective cover is removed.

[0052] It is understandable that the installation and removal of protective sleeves can effectively protect cables after disassembly and before restoration, preventing physical damage.

[0053] It should be noted that the protective cover is used for the protection of cables, and the specific type of protective cover can be set according to actual needs, without any restrictions.

[0054] like Figure 5 As shown, in some embodiments, the method further includes: The imaging recognition device 1 is set on the adjustment bracket 2, and the position and angle of the imaging recognition device 1 are adjusted by the adjustment bracket 2. The original DCS cabinet was scanned and imaged using imaging recognition device 1.

[0055] Understandably, the imaging recognition device 1 uses the adjusting bracket 2 to adjust its position and angle, thereby effectively scanning and imaging the original DCS cabinet, thus ensuring the efficient and accurate acquisition of the original layout diagram of the hardware equipment in the original DCS cabinet.

[0056] It should be noted that the imaging recognition device 1 is used to scan and image the original DCS cabinet using 3D imaging technology, while the adjustment bracket 2 is used to adjust the position and angle of the imaging recognition device 1. The specific types of the imaging recognition device 1 and the adjustment bracket 2 can be set according to actual needs and are not limited thereto. For example, the adjustment bracket 2 can be a multi-axis gimbal, and the imaging recognition device 1 is set on the multi-axis gimbal and its position and angle are adjusted using the multiple axial movements of the multi-axis gimbal.

[0057] The imaging recognition device 1 can help DCS hardware engineers understand the latest equipment layout of the existing DCS cabinet in a timely manner, which can effectively avoid errors in the upgrade and transformation plan caused by on-site resubmission and supplementation, while reducing the workload of on-site equipment survey.

[0058] In some embodiments, the hardware device includes: a controller, a power module, a cable tray, and a card.

[0059] For example, the original DCS cabinet contains controllers, power modules, cable trays, and cards. The modified DCS cabinet can contain the same or different types of controllers, power modules, cable trays, and cards.

[0060] It should be noted that during unit operation, preliminary identification, 3D imaging scanning, and modular fixing of signal cables can be carried out, which greatly reduces the impact of DCS transformation and upgrade work on unit operation.

[0061] The method in this embodiment takes into account the layout of the original DCS cabinet hardware during the initial card arrangement phase. The modified DCS cabinet layout is based on the original DCS cabinet, which is more conducive to subsequent cable connection restoration. Simultaneously, the modular cable fixing effectively avoids errors during cable removal and restoration, and improves the overall construction progress and accuracy.

[0062] In summary, using the method of this embodiment, DCS technicians can share the workload with other colleagues, enabling them to complete the main design work in the company's office space. The modular dismantling and restoration technology reduces the construction difficulty for construction personnel and improves the efficiency and accuracy of construction. Work that originally required highly specialized technicians can now be completed independently by general construction technicians using the method of this embodiment.
