[0077] The energy consumption control module is used to monitor and analyze the energy consumption of the computer room, and put forward energy-saving optimization suggestions, which are sent to the client through the local area network (LAN).

[0078] The BIM-based efficient computer room cable duct cutting and cable coding and energy consumption control method using the BIM-based efficient computer room cable duct cutting and cable coding and energy consumption control system includes the following process:

[0079] Step 1: BIM model building module uses BIM software to build Figure 2 The three-dimensional digital model of the computer room shown (hereinafter referred to as the BIM model) contains BIM three-dimensional information such as equipment location, cable duct direction and cable layout, ensuring the precise location of all components and the completeness of cable path information.

[0080] Step 2: The cable trunking pipe breaking module accurately locates the cable trunking pipe breaking position using the 3D coordinates in the BIM model generated in step 1, and generates a construction drawing of the cable trunking pipe breaking. The specific process is as follows:

[0081] Step 2.1: Confirm the accuracy of the BIM model: Verify that the BIM model is complete and error-free, and ensure that all relevant components (such as cable ducts and cabinets) are correctly modeled. Verify that the 3D coordinates of the components in the model are accurate, especially those related to cable ducts and cabinets.

[0082] Step 2.2: Determine the requirements for cable trunking pipe cutting: Clarify the specific location and quantity of cable trunking pipe cutting requirements; determine whether the pipe cutting location meets the requirements based on project requirements and design specifications;

[0083] Step 2.3: Accurately locate the cable trunking pipe breakage position: Find and locate the cable trunking that needs to be broken in the BIM model. Based on the cable trunking pipe breaking requirements in step 2.2, accurately mark the broken pipe position on the cable trunking;

[0084] Step 2.4: Generate a construction drawing of the broken cable trunking pipe: Create a new construction drawing in the BIM software and accurately mark the key information such as the broken pipe location, length, and angle on the construction drawing. Mark the location and size of other components related to the broken pipe (such as connectors and fixings). Output the construction drawing in an appropriate format (such as PDF, DWG, etc.) and distribute it to relevant personnel.

[0085] The broken pipe length is calculated by the broken pipe position (three-dimensional coordinates) in step 2.3:

[0086]

[0087] Among them, L is the length of the broken pipe, (x1, y1, z1) is the three-dimensional coordinate of the starting point of the broken pipe, and (x2, y2, z2) is the final dimensional coordinate of the broken pipe in the cable tray.

[0088] Step 3: The cable trunking pipe cutting module simulates the cable trunking pipe cutting process through the BIM model, discovers and solves potential problems in advance, reduces possible errors during construction, and improves material utilization efficiency.

[0089] Step 4: The cable path optimization module optimizes the cable path through the BIM model generated in step 1, taking into account factors such as the length of the path, the number of turns, and the intersections, and uses the optimization algorithm to analyze and calculate the optimal path of the cable. Figure 3 The specific process is as follows:

[0090] Step 4.1: Extract key data from the cable BIM model generated in Step 1, including the cable length, diameter, bend radius, start and end point locations, turning node locations, and relative positions to other equipment or structures.

[0091] Step 4.2: Based on the cable model data extracted in step 4.1, a preliminary cable routing path is generated, taking into account the basic cable direction, avoiding obstacles as much as possible, and meeting basic construction and safety requirements.

[0092] Step 4.3: Based on the preliminary cable routing generated in Step 4.2, consider factors such as cable path length, number of turns, number of intersections, and construction difficulty, and use the cable path optimization algorithm to calculate and analyze the optimal path that meets all constraints and output it. The specific formula of the cable path optimization algorithm is as follows:

[0093]

[0094] Where i represents the i-th node on the cable path, n represents the number of nodes on the cable path, S represents the minimum path length of the cable path, T represents the minimum number of turns in the cable path, (x i+1 ,y i+1 , z i+1 ) represents the three-dimensional coordinates of the i+1th node on the cable path, (x i+2 ,y i+2 , z i+2 ) represents the three-dimensional coordinates of the i+2th node on the cable path.

[0095] Step 5: The cable coding system module generates a unique code for each cable on the BIM model of the cable path optimization layout generated in step 4. The cable’s starting point, end point, and purpose are identified by the information in the model, and the cables are classified and grouped to reduce interference and signal loss. Figure 4 The specific process is as follows:

[0096] Step 5.1: Extract key data from the cable BIM model generated in Steps 1 and 4, including cable type, specification, length, start and end point locations, and cable path;

[0097] Step 5.2: Develop coding rules based on the actual situation and management requirements of the computer room. The coding should include key parameters such as location information and cable type.

[0098] The encoding format is as follows:

[0099] Generate a unique code for each cable in the format of CAB-{ID}-{starting point}-{end point}, where CAB is the cable type, {ID} is the unique identifier of the cable, and {starting point} and {end point} are the three-dimensional coordinates of the starting and ending points of the cable, respectively.

[0101] Step 5.4: Verify and conflict the cable codes generated in step 5.3 to ensure that the codes comply with the defined rules and are free of errors or omissions. Check whether there are coding conflicts between different cables and ensure that the codes of each cable are unique.

[0102] Step 5.5: After confirming that the cable coding is correct in step 5.4, store the verified and conflict-checked cable coding information in the BIM model. Use the database function of the BIM software to achieve the correspondence between the coding and the components; add coding tags to the model for easy management and query;

[0103] Step 5.6: After completing the storage of cable coding information in step 5.5, log records and notifications need to be output; log records are used to record detailed information about the entire cable coding process, including the execution time and results of each step; notifications are used to report the completion status of the cable coding work to relevant personnel so that they can proceed with the next step of work or decision-making.

[0104] Step 6: Based on the processing results of step 5, the cable coding system module generates a BIM model with optimized cable layout, and then generates and exports cable laying and management documents to facilitate subsequent maintenance and management.

[0105] Step 7: Install sensors and IoT devices to collect real-time environmental parameters (such as temperature, humidity, current, voltage, etc.) and equipment operating status data of the computer room. The sensors should cover key indicators to ensure the comprehensiveness and accuracy of the data. The collected data is transmitted to the data acquisition module and data processing module through the network for centralized storage and processing. Figure 1 The specific process is as follows:

[0106] Step 7.1: Install sensors and IoT devices: Install sensors and IoT devices in the computer room to collect environmental parameters and equipment operating status in real time.

[0111] Among them, D i is the i-th data collected by the sensor, C i is the i-th code in the BIM model, and f is the mapping function to ensure that the data and the code correspond one to one.

[0112] Step 8: Based on the data collected in step 7 and combined with the coding information in the BIM model, the energy consumption control module is used to accurately monitor and collect data on the energy consumption of the computer room, analyze energy consumption data, formulate and implement energy consumption data optimization plans and measures, and produce energy consumption reports.

[0115] Energy consumption monitoring and analysis requires calculating the total energy consumption and the energy consumption contribution of each device. The formula is as follows:

[0116]

[0117] Among them, E total is the total energy consumption, E i is the energy consumption of the i-th device, and n is the number of devices.

[0118] The energy consumption calculation formula for a single device is as follows:

[0119] E i =P i ×T i ;

[0120] Among them, P i is the power of the i-th device, T i is the running time of the i-th device.

Use OpenStudio software to build a computer room energy consumption data model, simulate different optimization plans and measures, and compare the simulated results of different energy-saving plans and measures to select the optimal energy consumption plan and measure for implementation.

[0122] The minimum total energy consumption optimization algorithm formula is as follows:

[0123]

[0124] The constraints are as follows:

[0125] T i ≤T max ;

[0126] P i ≤P max ;

[0127] Among them, P max is the maximum power allowed by the device, T max The maximum allowed operating time for the device.

[0128] Step 8.4: Report generation: The energy consumption control module regularly generates energy consumption reports, which record the energy consumption and energy-saving effects of the computer room in detail.

The specific formula for the cable path optimization algorithm is as follows: Where i represents the i-th node on the cable path, n represents the number of nodes on the cable path, S represents the minimum path length of the cable path, T represents the minimum number of turns in the cable path, (x i+1 ,y i+1 , z i+1 ) represents the three-dimensional coordinates of the i+1th node on the cable path, (x i+2 ,y i+2 , z i+2 ) represents the three-dimensional coordinates of the i+2th node on the cable path; The specific process of step 8 is as follows: Step 8.1: The energy consumption control module monitors the energy consumption data of the computer room in real time; Step 8.2: The energy consumption control module performs energy consumption analysis, identifies high-energy-consuming devices and areas, and understands the distribution, trends, and changing patterns of energy consumption; The total energy consumption calculation formula is as follows: Among them, E total is the total energy consumption, E i is the energy consumption of the i-th device, and n is the number of devices; The energy consumption calculation formula for a single device is as follows: AND i =P i ×T i ; Among them, P i is the power of the i-th device, T i is the running time of the i-th device; Step 8.3: Based on the analysis in Step 8.2, generate the energy consumption data for each device. With minimizing total energy consumption as the optimization goal, formulate energy consumption optimization plans and measures, including adjusting equipment operating parameters, optimizing environmental parameters, and improving equipment maintenance. Use OpenStudio software to build a data model for the computer room energy consumption, simulate different optimization plans and measures, and compare the simulated results of different energy-saving plans and measures to select the optimal energy consumption plan and measure for implementation. Among them, the minimum total energy consumption optimization algorithm formula is as follows: The constraints are as follows: T i ≤T max ; P i ≤P max ; Among them, P max is the maximum power allowed by the device, T max The maximum operating time allowed for the device; Step 8.4: The energy consumption control module regularly generates energy consumption reports, detailing the energy consumption and energy-saving effects of the computer room. The reports include energy consumption data, abnormal point analysis, and optimization suggestions. The specific process of step 5 is as follows: Step 5.1: Extract key data from the cable BIM model generated in Steps 1 and 4, including cable type, specification, length, start and end point locations, and cable path; Step 5.2: Develop coding rules based on the actual situation and management requirements of the computer room: Generate a unique code for each cable in the format of CAB-{ID}-{starting point}-{end point}, where CAB is the cable type, {ID} is the unique identifier of the cable, and {starting point} and {end point} are the three-dimensional coordinates of the starting and ending points of the cable, respectively. Step 5.3: Automatically generate a unique code for each cable according to the coding rules established in step 5.2; Step 5.4: Verify and check for conflicts on the cable code generated in step 5.3; Step 5.5: Store the verified and conflict-checked cable coding information in the BIM model, and use the database function of the BIM software to achieve the correspondence between the coding and the components; add coding tags to the model for easy management and query; Step 5.6: Output log records and notifications. The log is used to record detailed information about the entire cable coding process, including the execution time and results of each step. The notification is used to report the completion status of the cable coding work to relevant personnel. The specific process of step 7 is as follows: Step 7.1: Install sensors and IoT devices in the computer room to collect environmental parameters and equipment operating status in real time; Step 7.2: The collected data is transmitted to the data acquisition module, data processing module, and energy consumption control module through the network; Step 7.3: The energy consumption control module associates the collected data with the coded information in the BIM model to form a complete data link; data tags are added to the BIM model to display the operating status and environmental parameters of the equipment in real time; When associating the collected data with the codes in the BIM model, the data mapping formula used is as follows: D i =f(C i ); Among them, D i is the i-th data collected by the sensor, C i is the i-th code in the BIM model, and f is the mapping function to ensure that the data and the code correspond one to one.
