[0003] At present, the arrangement modes of components and elements of the environmental control cabinet of rail transit are various, there is no unified standard, and the arrangement results have great uncertainty due to different experiences of designers, requirements of the first party and design principles of manufacturers.

[0004] The technical personnel in the field urgently need a set of standard principles and algorithms about the configuration, bus dividing, cabinet dividing and spare parts of components and elements in the environmental control cabinet, so as to optimize and standardize the arrangement of components and elements and the spare part process in the design of the environmental control cabinet of rail transit. SUMMARY

[0005] The application aims at the deficiencies of the prior art, and provides an intelligent cabinet dividing algorithm suitable for the environmental control cabinet of rail transit.

[0006] The application is achieved by the following technical scheme:

[0007] An intelligent cabinet dividing algorithm suitable for the environmental control cabinet of rail transit, characterized in that the intelligent cabinet dividing algorithm comprises the following steps:

[0008] (S1) importing a standard input file, and configuring the module number, load level, function and required coefficient of each component and element in the standard input file;

[0009] (S2) traversing all the components and elements, and initially grouping each component and element through the environmental control room end position, environmental control room layer position and load level of the component and element; after the initial grouping is completed, secondarily grouping each component and element through the mutual exclusion relationship, correlation relationship and preset condition of the bus total load of each component and element;

[0010] (S3) after the secondary grouping, placing each component and element and spare component and element into the corresponding environmental control cabinet through the set spare part principle and the calculated cabinet number.

[0011] Step (S1) is: importing the standard input file, configuring the load level, function of the component in the standard input file; configuring the default power factor of the component; configuring the need coefficient of the component; matching to the function configuration table corresponding to the function according to the function of the component, configuring the analog-digital of the component according to the function configuration table.

[0012] Step (S2) is:

[0013] (S2.1) traversing all the components, executing the following loop:

[0014] temporarily grouping according to the load level, chamber end position, chamber layer position of the component:

[0015] Each temporary group is divided into two mutually exclusive groups, namely a heavy mutual exclusion group and a light mutual exclusion group, according to the mutual exclusion relationship; the mutual exclusion relationship refers to a heavy mutual exclusion keyword and a light mutual exclusion keyword;

[0016] Each temporary group generates an associated group according to the association relationship principle (XX / *-YY); wherein (XX / *-YY) refers to the numbering method of the component, and when the numbers XX and YY in the component are the same, they are filtered into the same associated group;

[0017] (S2.2) after the loop in step (S2.1) ends, initially grouping according to the chamber end position of the component, generating an initial group;

[0018] (S2.3) according to the data of the initial group, grouping twice according to the chamber layer position of the component, generating a secondary group; according to the data of the secondary group and the load level of the component, grouping three times to generate an initial bus, and calculating the total capacity of each initial bus;

[0019] (S2.4) traversing all the initial buses, executing the following loop: calculating the total capacity of each initial bus; the number of sub-buses contained in each initial bus = total capacity / initial bus maximum capacity; if the number of mutually exclusive groups is greater than the calculated number of sub-buses, the number of sub-buses is the larger one;

[0020] (S2.5) first, the mutually exclusive groups are distributed into the sub-buses; the associated groups are distributed into each sub-bus; the components not distributed in each initial bus are sorted according to capacity; checking whether the number of components not distributed in each initial bus is greater than 0:

[0021] If greater than 0, the unassigned components are assigned to the sub-bus with the smallest capacity, and then the total capacity of the sub-bus is updated; return to check again whether the number of unassigned components in each of the initial buses is greater than 0:

[0022] If less than or equal to 0, the grouping of the sub-buses is completed, and the loop ends.

[0023] Step (S3) is:

[0024] (S3.1) Traverse all the sub-buses, execute the following loop, calculate the incoming line capacity, and the calculation formula is:

[0025]

[0026] In the formula, p i is the capacity of the i-th device; i x is the need coefficient of the i-th device; k 散柜 is the number of cabinets of the sub-bus; i sum is the sum of the heights of the components of the sub-bus;

[0027] According to the incoming line capacity, configure the module number of double-power incoming line and single-power incoming line; calculate the module number of the open cabinet of each sub-bus, count the number of cabinets, and calculate the number of open cabinets, and the calculation formula is:

[0028]

[0029] In the formula, n 散柜 is the number of cabinets of the sub-bus; m sum is the sum of the heights of the components of the sub-bus; M is the overall cabinet height of the cabinet type;

[0030] Calculate the total module number of the open cabinet;

[0031] Each of the components is sorted according to the module number; and each of the components is further sorted according to the power on the basis of the module number sorting;

[0032] (S3.2) According to the maximum spare part scheme; according to each of the components having a spare component, calculate the total module number of the components; judge whether the total module number of the maximum spare part scheme is greater than or equal to the total module number of the open cabinet;

[0033] If the total module number of the maximum spare part scheme is less than the total module number of the open cabinet, calculate the remaining module number after the total module number of the open cabinet is subtracted from the total module number of the maximum spare part scheme; increase the spare part of the minimum module number of the "power distribution" function of the component; update the total module number of the maximum spare part scheme; then return to judge again whether the total module number of the maximum spare part scheme is greater than or equal to the total module number of the open cabinet;

[0034] If the total modulus of the maximum spare parts scheme is greater than or equal to the total modulus of the cabinet, it is determined whether the total modulus of the maximum spare parts scheme is equal to the total modulus of the cabinet. If the result is no, the last spare component is deleted. Then, it is determined whether the total modulus of the maximum spare parts scheme is equal to the total modulus of the cabinet. If the result is no, it means that the maximum spare parts scheme is not feasible, and all spare components are deleted.

[0035] (S3.3) The minimum spare parts scheme is executed. The number of the components with the same modulus and power is counted and sorted in reverse order. It is determined whether the total modulus of the minimum spare parts scheme is less than the total modulus of the cabinet.

[0036] If the total modulus of the minimum spare parts scheme is less than the total modulus of the cabinet, it is further determined whether the components with the same modulus and power are greater than or equal to 7. If they are greater than or equal to 7, 3 spare components are prepared for the components with the same modulus and power of 7 or more. The total modulus of the minimum spare parts scheme is updated. Then, it is determined again whether the total modulus of the minimum spare parts scheme is less than the total modulus of the cabinet.

[0037] If the total modulus of the minimum spare parts scheme is greater than or equal to the total modulus of the cabinet, it is further determined whether the components with the same modulus and power are greater than or equal to 5. If they are greater than or equal to 5, 2 spare components are prepared for the components with the same modulus and power of 7 or less and 5 or more. The total modulus of the minimum spare parts scheme is updated. Then, it is determined again whether the total modulus of the minimum spare parts scheme is less than the total modulus of the cabinet. If it is less than 5, it is further determined whether the components with the same modulus and power are greater than or equal to 3.

[0038] If the components with the same modulus and power are greater than or equal to 3, 1 spare component is prepared for the components with the same modulus and power of 5 or less and 3 or more. The total modulus of the minimum spare parts scheme is updated. Then, it is determined again whether the total modulus of the minimum spare parts scheme is less than the total modulus of the cabinet.

[0039] If the components with the same modulus and power are less than 3, 1 spare component is prepared for the components with the same modulus and power of 3 or less. The total modulus of the minimum spare parts scheme is updated. Then, it is determined again whether the total modulus of the minimum spare parts scheme is less than the total modulus of the cabinet.

[0040] (S3.4) It is determined whether the total modulus of the minimum spare parts scheme is equal to the total modulus of the cabinet. If yes, it returns to step (S3.1). If no, the last spare component is deleted, the remaining modulus is calculated, and the "power distribution" spare component is configured according to the remaining modulus.

[0041] The advantages of this invention are: it standardizes the cabinet division algorithm for rail transit environmental control cabinets and provides multiple component configuration tables as the basis for algorithm configuration; it provides a generalized and standardized basis for the cabinet division algorithm of rail transit environmental control cabinets, thereby improving design efficiency and accuracy.

[0051] The features and other related features of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate understanding by those skilled in the art:

[0052] Example: Figures 1-9 As shown, this embodiment specifically relates to an intelligent cabinet allocation algorithm suitable for rail transit environmental control cabinets. The intelligent cabinet allocation algorithm includes the following steps:

[0053] (S1) As Figure 1 , 2 As shown in Figures 3, 4, and 8, starting with the standard input file for the components, the module, load level, function, and demand factor of each component are configured in the standard input file. More specifically:

[0054] Import the standard input file, and configure the load level and function of the components in the standard input file; for example... Figure 1The example format and data of the standard input file in the embodiment are shown as follows: Figure 2 The table of load level and function configuration of the component in the embodiment is shown as follows, wherein the first three columns are the judgment basis, and the last two columns are the judgment result. The load level and function of the component are judged by judging the name, working condition and power of the component. It should be noted that the components supported in the embodiment are: Mabao, thermal relay, power distribution, soft start, frequency conversion, single power line, and double power line. The load levels supported in the embodiment are: first-level load, second-level load and third-level load.

[0055] The default power factor of the component is configured.

[0056] The need coefficient of the component is configured, for example, Figure 3 The need coefficient configuration of the component is shown as follows. The specific need coefficient can be referred to the attached table. Figure 3 The default value is 1.0 in other cases.

[0057] According to the function of the component, the function configuration table corresponding to the function is matched, and the modulus of the component is configured according to the function configuration table, for example, Figure 4 as shown.

[0058] (S2) As shown in Figure 8 , all components are traversed, and the components are preliminarily grouped by the ring control room end position, ring control room layer position and load level of the components. After the preliminary grouping is completed, the components are secondarily grouped by the mutual exclusion relationship, association relationship and preset condition of the bus total load of the components. The details are as follows:

[0059] (S2.1) All components are traversed, and the following loop is executed:

[0060] The components are temporarily grouped according to the load level, ring control room end position and ring control room layer position of the components;

[0061] Each temporary group is divided into two mutually exclusive groups, i.e., a heavy mutual exclusion group and a light mutual exclusion group, according to the mutual exclusion relationship. The mutual exclusion relationship refers to a heavy mutual exclusion keyword and a light mutual exclusion keyword. The keyword for mutual exclusion is the name of the component, which is set by the user. The heavy mutual exclusion keyword (default): tunnel fan; chilled water pump; combined air conditioning unit. The light mutual exclusion keyword (default): jet fan; air valve cabinet. The mutual exclusion is judged according to the keyword set by the user and the name of the component. When the bus is divided, the components in the heavy mutual exclusion group will not be allocated to the same bus. The light mutual exclusion group allows at most two same light mutual exclusion components to be placed in the same bus.

[0062] Each temporary group is generated into an associated group according to the association principle (XX / *-YY); wherein (XX / *-YY) refers to the numbering mode of the component, and the component is filtered into the same associated group when the XX field and the YY field in the component are the same. For example, "K2 / XK-A1", "K2 / XHPF-A1", "K2 / DT-A1" can be filtered into a group of components, saving the time of manual grouping of users. When the associated groups are generated, there is a prerequisite that the load levels are the same. Subsequently, the components in the same group can be placed in a busbar.

[0063] It should be noted that the end position of the environmental control room refers to A end, B end, C end, and D end. The floor position of the environmental control room refers to the first floor above ground, the second floor above ground, the third floor above ground, the first floor underground, the second floor underground, the third floor underground, and the fourth floor underground.

[0064] (S2.2) After the loop in step (S2.1) ends, the components are initially grouped according to the end position of the environmental control room, and the initial groups are generated.

[0065] (S2.3) According to the data of the initial groups, the components are secondarily grouped according to the floor position of the environmental control room, and the secondary groups are generated; according to the data of the secondary groups and the load levels of the components, the components are thirdly grouped, the initial busbars are generated, and the total capacity of each initial busbar is calculated.

[0066] It should be noted that the supported busbar types in the embodiment are: first-level load busbar, second-level load busbar, and third-level load busbar.

[0067] (S2.4) All initial busbars are traversed, and the following loop is executed:

[0068] The total capacity of each initial busbar is calculated; the number of sub-busbars contained in each initial busbar = total capacity / maximum capacity of initial busbar; it should be noted that the supported sub-busbar types in the embodiment are: each level of load busbar can be divided into a sub-busbar according to the maximum capacity of 220kW, so the sub-busbar is divided into a first-level load sub-busbar, a second-level load sub-busbar, and a third-level load sub-busbar; the maximum capacity of the sub-busbar is 220kW.

[0069] If the number of mutually exclusive groups is greater than the calculated number of sub-busbars, the number of sub-busbars is taken as the greater one.

[0070] (S2.5) First, the mutually exclusive groups are distributed into the sub-busbars; the associated groups are distributed into the sub-busbars; the components in each initial busbar that are not distributed are sorted according to the capacity; it is checked whether the number of the components in each initial busbar that are not distributed is greater than 0:

[0071] If the number is greater than 0, the unassigned components are assigned to the bus with the smallest capacity, and then the maximum capacity of the bus is updated; then, the system returns to check again whether the number of unassigned components in each initial bus is greater than 0.

[0072] If the value is less than or equal to 0, then the grouping of the parent and child lines is complete, and the loop ends.

[0073] (S3) such as Figure 5 , 6 As shown in Figures 7 and 9, after the secondary grouping, each component and the spare components are placed in the corresponding environmental control cabinet according to the set spare parts principle and the calculated number of cabinets, as follows:

[0074] (S3.1) Traverse all busbars and sub-busbars, execute the following loop, and calculate the incoming line capacity using the following formula:

[0075]

[0076] In the formula, p i For the first i The capacity of each device; k x : No. i The demand factor for each piece of equipment.

[0077] Based on the incoming line capacity, configure the modules for dual-power incoming lines and single-power incoming lines; calculate the module of each individual cabinet on each busbar, count the number of cabinets in the entire system, and calculate the total number of individual cabinets using the following formula:

[0078]

[0079] In the formula, n 散柜 The number of individual cabinets for the aforementioned busbar; m sum The sum of the heights of the components of the busbar; M This refers to the total height of the cabinet.

[0080] It should be noted that the supported cabinet types in this embodiment are MNS2.0, MNS3.0, Blokset, Okken, 8PT, and S8. Cabinet types are divided into complete cabinets and individual cabinets. A complete cabinet contains only one component; an individual cabinet contains multiple components. The module of the components is configured according to the cabinet type, such as... Figure 5 The diagram shows the cabinet types, modules, cabinet heights, and suffixes supported by the algorithm in this embodiment; for example... Figure 6 The table shown is a configuration table of cabinet types, single power supply input modules, and single surge input modules used in this embodiment. If the cabinet type is different for each project, this configuration table needs to be configured separately. For example... Figure 7The configuration table shown is the external modulus and internal height of all cabinet types supported by the algorithm of the present embodiment. The external modulus provides the modulus name for the cabinet manufacturer, and the height is the height parameter of the algorithm corresponding to the modulus. Wherein "… / …" means: the number before " / " represents the height, and the number before " / " represents the width coefficient.

[0081] The total modulus of the open cabinet is calculated.

[0082] Each component is sorted according to the modulus; each component is further sorted according to the power on the basis of the modulus sorting.

[0083] (S3.2) According to the fact that each component has a standby component, the total modulus of the components is calculated; it is judged whether the total modulus of one component plus one standby component is greater than or equal to the total modulus of the open cabinet;

[0084] If the total modulus of one component plus one standby component is less than the total modulus of the open cabinet, the remaining modulus after the total modulus of the open cabinet is subtracted from the total modulus of one component plus one standby component is calculated; the standby component of the minimum modulus of the "power distribution" function of the component is increased; the total modulus of one component plus one standby component is updated; then it is returned to judge again whether the total modulus of one component plus one standby component is greater than or equal to the total modulus of the open cabinet;

[0085] If the total modulus of one component plus one standby component is greater than or equal to the total modulus of the open cabinet, it is further judged whether the total modulus of one component plus one standby component is equal to the total modulus of the open cabinet, and if the result of the judgment is no, the last standby component is deleted; then it is continued to judge whether the total modulus of one component plus one standby component is equal to the total modulus of the open cabinet, and if the result of the judgment is no, it is indicated that the scheme of one component plus one standby component is not feasible, and all standby components are deleted.

[0086] (S3.3) According to the minimum standby component scheme, the number of components with the same modulus and power is counted and sorted in reverse order; it is judged whether the total modulus of the minimum standby component is less than the total modulus of the open cabinet;

[0087] If the total modulus of the minimum standby component is less than the total modulus of the open cabinet, it is further judged whether the components with the same modulus and power are greater than or equal to 7, and if they are greater than or equal to 7, three standby components are prepared for the components with the same modulus and power of 7 or more; the total modulus of the minimum standby component is updated; then it is returned to judge again whether the total modulus of the minimum standby component is less than the total modulus of the open cabinet;

[0088] If the total modulus of the minimum spare parts is greater than or equal to the total modulus of the distribution cabinet, it is further determined whether the same modulus and power components are greater than or equal to 5; if greater than or equal to 5, 2 spare components are prepared according to the same modulus and power components less than 7 and greater than or equal to 5; the total modulus of the minimum spare parts is updated; then it is returned to determine again whether the total modulus of the minimum spare parts is less than the total modulus of the distribution cabinet; if less than 5, it is further determined whether the same modulus and power components are greater than or equal to 3;

[0089] If the same modulus and power components are greater than or equal to 3, 1 spare component is prepared according to the same modulus and power components less than 5 and greater than or equal to 3; the total modulus of the minimum spare parts is updated; then it is returned to determine again whether the total modulus of the minimum spare parts is less than the total modulus of the distribution cabinet;

[0090] If the same modulus and power components are less than 3, 1 spare component is prepared according to the same modulus and power components less than 3; the total modulus of the minimum spare parts is updated; then it is returned to determine again whether the total modulus of the minimum spare parts is less than the total modulus of the distribution cabinet.

[0091] (S3.4) It is determined whether the total modulus of one component and one spare component is equal to the total modulus of the distribution cabinet; if yes, it is returned to step (S3.1); if no, the last spare component is deleted, the remaining modulus is calculated, and the "power distribution" spare component is configured according to the remaining modulus.

[0092] The beneficial effects of the embodiment are that the distribution cabinet algorithm of the rail transit environmental control cabinet is standardized, and multiple component configuration tables are provided as configuration basis of the algorithm. The distribution cabinet algorithm of the rail transit environmental control cabinet is provided with general and standardized basis, and the design efficiency and accuracy are improved.
