Description

Technical Field

[0001] This invention relates to urban rail transit signaling systems, and more particularly to a method for modifying signaling system equipment rooms used in urban rail transit. Background Technology

[0002] Signal system equipment room layout design is used to indicate the relative positions of equipment to buildings and between equipment itself. It is an important technical document guiding equipment installation and wiring. As early-built urban rail transit lines gradually enter their major overhaul period, the focus on major renovations has been increasing. To improve capacity and system reliability and safety, it often involves replacing existing systems with new signaling systems. Currently, traditional design lacks a standardized methodology. Designers often rely on experience or simply follow the "Metro Design Code" (GB50157-2013) to design the indoor spacing of signaling equipment. This primitive method is based on new projects, such as station hall floor plans and sectional drawings with relatively accurate data, and the design of vacant equipment rooms. As long as the cabinet dimensions and quantity are accurately calculated, and the anti-interference spacing requirements of each cabinet are met, the design can be carried out according to the drawings after the equipment arrives on site.

[0003] Traditional designs are insufficient for major renovation projects, most of which involve lines that were built a long time ago and whose existing equipment is nearing retirement. Existing station drawings often contain discrepancies between the actual equipment room size and layout shown in the station concourse cross-section drawings and the actual facilities, due to storage, management, and changes. Furthermore, during signal system equipment room renovations, a long transition period is required where new equipment shares rooms with older equipment. The lack of scientifically sound and reasonable design and verification methods for existing line equipment room renovations can render designs unusable, leading to situations where, after the equipment arrives on-site, the spacing between devices is found to be completely inadequate, resulting in extensive rework and even interference with existing operational equipment. Currently, the industry has not yet developed an effective method for addressing this issue of signal equipment room renovations. Summary of the Invention

[0004] This invention proposes a method for upgrading a rail transit signaling system equipment room. This method can identify problems early in the early stages of equipment room design and verification, analyze the impact in advance, and scientifically plan the design, avoiding rework caused by unusable designs and effectively solving the usability and security issues of equipment room upgrades.

[0005] To achieve the above objectives, this invention proposes a method for modifying a rail transit signaling system equipment room, comprising the following steps:

[0006] S1. Model the new equipment and create a physical measurement board;

[0007] S2. Model the computer room and its existing equipment;

[0008] S3. Analyze the spacing between each piece of equipment and design a preliminary feasibility plan for the renovation of the computer room based on the computer room model and the new equipment model.

[0009] S4. The preliminary feasibility plan is verified and improved using the physical measurement board of the new equipment, and a final modification plan is formed.

[0010] Furthermore, step S1 specifically includes the following steps:

[0011] Based on the system configuration of the signal system room, determine the new equipment required for the room renovation, including the name, quantity and size of the new equipment, and compile a statistical table.

[0012] Model each new device based on the aforementioned statistical table;

[0013] A physical measuring plate is formed based on the width and depth of each new device.

[0014] Furthermore, step S2 specifically includes the following steps:

[0015] Obtain the configuration information of the equipment room from the signal system as-built documentation;

[0016] Based on this configuration information, a model of the computer room and its existing equipment is created to obtain the computer room model.

[0017] Furthermore, the configuration information includes the civil engineering plan of the computer room, room dimensions, number and size of existing server racks, and layout.

[0018] Furthermore, the method for analyzing the spacing between each piece of equipment in step S3 specifically includes the following steps:

[0019] Analyze the spacing between each piece of equipment to determine the interference distance and cabinet door distance factors when arranging existing old equipment. Also determine the impact of room space, existing old cabinets on the arrangement of new cabinets, and cable trays on the arrangement of new cabinets.

[0020] Furthermore, when designing the server room renovation in step S3, it is necessary to consider the distance between the new equipment and the existing old equipment, the impact of the opening and closing distance of the cabinet doors of the new and old equipment, the impact of the removal of the existing old equipment on the new cabinet, the mutual influence between the existing cabinet cable trays and partitions and the new cabinets and cable trays, and the overall layout specifications of the new equipment after the removal of the existing old equipment.

[0021] Furthermore, step S4 specifically includes the following steps:

[0022] During the verification process, the preliminary feasibility plan was adjusted based on the actual layout location and other factors.

[0023] The adjusted feasibility plan was then improved based on the technical specifications to obtain the final renovation plan.

[0024] Furthermore, if the configuration information of the computer room cannot be obtained, the feasibility of the physical measurement board of the new equipment is designed directly in the actual computer room, and the influence of various factors is considered for verification.

[0025] Furthermore, the factors include interference distance, cabinet door distance, available space in the computer room, the impact of existing old equipment on the layout of new equipment, and the impact of cable trays on the layout of new equipment.

[0026] This invention has the following advantages:

[0027] This invention models the computer room and its existing equipment, as well as the new equipment required for the renovation. Based on the spacing of each piece of equipment, a preliminary feasibility plan for the computer room renovation is designed. Then, a physical measurement board of the new equipment is placed in the actual computer room to verify the preliminary feasibility plan. This allows for early detection of problems during the early computer room design and verification process, early analysis of the impact, and scientific planning of the renovation design. It avoids rework caused by unusable renovation designs and interference with existing equipment, effectively solving the problems of availability and security of computer room layout in renovation projects.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0032] like Figure 1 As shown, this invention proposes a method for modifying a rail transit signaling system equipment room, comprising the following steps:

[0033] S1. Model the new equipment and create a physical measurement board;

[0034] Specifically, based on the system configuration of the signal system equipment room, the new equipment required for the equipment room renovation is determined, including the equipment name, quantity, and size, and a statistical table is generated. Since the quantity and size of the equipment may differ from the actual situation, this statistical table provides a basis for equipment modeling. Taking a centralized station as an example, the size and quantity of each new piece of equipment are determined based on the system configuration, as shown in the table below:

[0035] Table 1. Statistics on New Equipment Required for Computer Room Renovation

[0036] Equipment Name quantity Rack dimensions (width × depth × height mm) modular cabinet 4 960×450×2250 Interface cabinet 1 960×450×2250 Lightning protection distribution cabinet 1 960×450×2250 Transition cabinet 1 960×450×2250 Monitoring cabinet 1 960×450×2250 ODF patch panel 1 850×800×2250 Backbone network cabinet 1 600×800×2250 LATS rack 1 600×800×2250 iLOCK cabinets 2 600×800×2250 MSS rack 1 600×800×2250 Axle counting cabinet 2 600×800×2250 Power Screen 4 800×600×2250 voltage stabilizer cabinet 2 600×600×2250 UPS cabinet 2 550×800×1800 Battery rack 2 2000×600×1600

[0037] Based on the aforementioned statistical table, a model is created for each new device. Simultaneously, a physical measurement template is formed based on the width and depth of each new device.

[0038] S2. Model the computer room and its existing equipment.

[0039] Specifically, the configuration information of the equipment room is obtained from the signal system's as-built documentation, including the room's civil engineering plan, room dimensions, the number and size of existing server racks, and their layout. Based on this configuration information, a model of the equipment room and its existing equipment is created, resulting in the equipment room model, such as... Figure 2 As shown. Environmental factors need to be considered during the modeling process, such as whether there are obstructions and the location of cable trays.

[0040] S3. Analyze the spacing between each piece of equipment and design a preliminary feasibility plan based on the computer room model and the new equipment model.

[0041] Specifically, the spacing between each piece of equipment is analyzed to determine the spacing when arranging existing equipment, such as interference distance and cabinet door distance. At the same time, the room's available space, the arrangement of existing cabinets with new cabinets, and the impact of cable trays on the arrangement of new cabinets are also analyzed.

[0042] Based on the data center model and considering the equipment layout spacing, a preliminary layout of the new equipment is planned. The design needs to consider the distance between the new and existing equipment, the impact of the opening and closing distances of the cabinet doors, the impact of removing existing equipment on the new cabinets, the mutual influence between existing cabinet cable trays and obstructions and the new cabinets / cable trays, and the overall layout specifications of the new equipment after the removal of existing equipment. This will form a preliminary feasibility plan based on existing data. Figure 3 As shown.

[0043] S4. The preliminary feasibility plan is verified and improved using the physical measurement board of the new equipment, and a final modification plan is formed.

[0044] Specifically, the preliminary feasibility plan is verified using the physical measurement board of the new equipment formed in step S1, that is, actual on-site measurements are conducted based on the preliminary feasibility plan. The physical measurement board of the new equipment provides a direct visual understanding of its layout and location, including the relative positions of the old and new equipment. During the verification process, the preliminary feasibility plan is adjusted based on the actual environment, including the influence of the actual layout and other factors. The adjusted feasibility plan is then refined according to technical specifications, ultimately resulting in the modification plan.

[0045] Furthermore, if the configuration information of the computer room cannot be obtained, i.e., it is impossible to model the computer room based on the configuration information, then the physical measurement board of the new equipment is directly used to design a feasibility solution in the actual computer room, while considering the influence of various factors for verification. These factors include interference distance, cabinet door distance, spare space in the computer room, the impact of existing old equipment on the layout of the new equipment, and the impact of cable trays on the layout of the new equipment.

[0046] This invention models the computer room and its existing equipment, as well as the new equipment required for the renovation. Based on the spacing of each piece of equipment, a preliminary feasibility plan for the computer room renovation is designed. Then, a physical measurement board of the new equipment is placed in the actual computer room to verify the preliminary feasibility plan. This allows for early detection of problems during the early computer room design and verification process, early analysis of the impact, and scientific planning of the renovation design. It avoids rework caused by unusable renovation designs and interference with existing equipment, effectively solving the problems of availability and security of computer room layout in renovation projects.

Therefore, the scope of protection of the present invention should be defined by the appended claims.
