[0031] Combine the following Figure 1-Figure 7 A control device for rail transit according to an embodiment of the present invention is described.

[0032] An embodiment of the present invention provides a control device for rail transportation, such as Figure 1 and Figure 2 As shown, the control device for rail transit includes a plurality of module combination cabinets, and the module combination cabinets include a cabinet 100, Figure 1 and Figure 2A cabinet is schematically shown in the figure, in which a plurality of layers are separated in the height direction inside the cabinet 100, and the plurality of layers include a multi-layer electrical control layer 110 arranged inside the cabinet 100 and an interface layer 120 arranged on the top of the cabinet 100, the electrical control layer 110 includes a plurality of mounting positions 111, the mounting positions 111 are used to install electrical modules 140, the electrical modules 140 are connected inside the cabinet 100, and the interface layer 120 is used to connect between a plurality of module combination cabinets.

[0033] It can be understood that the module combination cabinet adopts a modular design, and different module combination cabinets have different uses, so the module combination cabinets for various purposes are designed based on the purpose. The electrical module 140 in the cabinet 100 of the module combination cabinet is arranged at the installation position 111 of the electrical control layer 110 according to the corresponding purpose, and the electrical module 140 is pre-connected in the cabinet 100, so that the internal wiring work of the cabinet 100 of different module combination cabinets is completed by the manufacturer in the prefabrication stage; and an interface layer 120 is set on the top of the cabinet 100, and the interface layer 120 is connected to the corresponding electrical module 140 in the cabinet 100 as required, and the connection between the module combination cabinets is realized through the interface layer 120.

[0034] It should be noted that in the related art, the combination cabinets in the computer room are designed with the combination as a unit. The different types of electrical modules in the cabinet are cross-arranged in the combination cabinet, and sufficient cabinet space is used as much as possible according to the number of combination requirements. Multiple different types of electrical modules are combined in one cabinet, and the internal wiring of the cabinet is led to the back of the corresponding side terminal of the layer through the electrical module contact. The layers are connected by wiring through the front of the corresponding side terminals, and the cabinets are connected by wiring through the corresponding side terminals. However, the wiring inside the cabinet, between the layers of the cabinet, and between the cabinets are all connected by on-site wiring and welding, resulting in a large workload on site, and the construction quality depends on the on-site construction environment and the skill level of the operator. The threshold for welding wire operation skills is high. Although it is possible to train highly skilled personnel by increasing efforts, the conditions on the construction site are poor, the quality of manual welding wires is difficult to guarantee, and there are certain quality risks. The module combination cabinet of the present invention adopts a modular design, and the electrical modules 140 of different module combination cabinets have corresponding standardized combination methods, so that the internal wiring of the cabinet 100 is completed in advance by the manufacturer, and an interface layer 120 connected to the electrical module 140 is set on the top of the cabinet 100. At the construction site, the wiring connection between the module combination cabinets can be achieved only through the interface layer 120, which greatly reduces the workload of on-site operations, reduces on-site labor, reduces the technical difficulty and construction risks of on-site construction, improves the quality of the project, and ensures railway safety production.

[0035] It should be noted that the electrical module 140 of this embodiment may be an electronic control device such as a circuit breaker, a transformer, a relay, a resistor and capacitor element, or a collection module.

[0036] The control equipment for rail transit provided in the embodiment of the present invention adopts a modular design for the module combination cabinet, so that the internal wiring work of the cabinet 100 of different module combination cabinets is completed by the manufacturer in the prefabrication stage, and an interface layer 120 is set on the top of the cabinet 100. At the construction site, the wiring connection between the module combination cabinets can be achieved only through the interface layer 120 on the top of the cabinet 100, thereby reducing the workload of on-site operations.

[0037] In one embodiment of the present invention, the existing combined cabinet in the machine room includes a plurality of cabinets, each cabinet is divided into a plurality of layers in the height direction, each layer has a plurality of installation positions, the cabinet side has a plurality of terminal layers corresponding to the plurality of layers, each terminal layer has a side terminal corresponding to the plurality of installation positions, the internal wiring of the cabinet is led to the back of the corresponding side terminal of the corresponding terminal layer through the electrical module contact of the installation position, and the terminal number identification corresponding to the side terminal is set on the cabinet, so as to realize the connection of the electrical module contact of the corresponding installation position when the wiring is connected between the side terminals. It should be noted here that the installation position is used to install the electrical module, and the electrical connection position of the electrical module on the installation position serves as the electrical module contact.

[0038] For example, the combined cabinet in the existing machine room includes cabinet A and cabinet B. Different types of electrical modules are randomly combined in cabinet A and cabinet B. When the electrical module A1 in one of the installation positions on the third layer of cabinet A is wired and connected with the electrical module A2 in one of the installation positions on the fourth layer, the side terminal C1 connected by the wiring of the electrical module A1 and the side terminal C2 connected by the wiring of the electrical module A2 are wired and welded to realize the wiring connection between the electrical module A1 and the electrical module A2 between the layers inside the cabinet. Obviously, the existing method requires the electrical module 140 to be connected to the wiring connection of the corresponding side terminal of the current layer and the wiring connection of the side terminal, which means that the workload of on-site wiring in the signal machine room is large. Figures 2 to 5 As shown, in the embodiment of the present invention, when the electrical module A1 at one of the installation positions 111 on the third layer of the cabinet A is wired and connected with the electrical module A2 at one of the installation positions 111 on the fourth layer, the electrical module A1 is directly wired and connected with the electrical module A2, eliminating the wiring connection from the electrical module 140 to the corresponding side terminal of the current layer, thereby greatly reducing the workload of on-site operations.

[0039] In one embodiment of the present invention, Figure 2 As shown, the interface layer 120 includes a plurality of electrical interfaces 121 disposed on the top layer of the cabinet 100 . The electrical interface 121 is connected to at least one electrical module 140 . The electrical interface 121 is used for connection between the cabinets 100 .

[0040] It is understandable that the multiple electrical interfaces 121 on the top layer of the cabinet 100 can be connected to one or more electrical modules 140 in the cabinet 100, and can be reasonably designed according to the connection requirements of the electrical modules 140 between the modular cabinets. It should be noted here that when the modular cabinet includes multiple cabinets 100, the electrical interface 121 can realize the connection between multiple cabinets 100 of the same modular cabinet, and of course, the electrical interface 121 can also realize the connection between cabinets 100 of different modular cabinets.

[0041] For example, the electrical interface 121 between the cabinets 100 can be connected by plugging, so that an interface layer 120 is set in the module combination cabinet, the existing side terminals are eliminated, and according to the wiring technical requirements and quantity, suitable plug-in devices and bundled cables are selected for plug-in connection, reducing the workload of on-site plug-in or welding.

[0042] Specifically, multiple electrical modules 140 that need to be connected between cabinets 100 can be connected to the same electrical interface 121, and the connection of multiple electrical modules 140 between cabinets 100 can be achieved through one electrical interface 121. For example, Figure 7 As shown, the module combination cabinet includes four cabinets 100, which are respectively recorded as cabinet A, cabinet B, cabinet C and cabinet D from left to right. Cabinet A has three electrical interfaces 121, which are respectively recorded as the first electrical interface, the second electrical interface and the third electrical interface. All electrical modules 140 in cabinet A that need to be connected to cabinet B are connected to the first electrical interface, and the first electrical interface is connected to cabinet B. All electrical modules 140 in cabinet A that need to be connected to cabinet C are connected to the second electrical interface, and the second electrical interface is connected to cabinet C. All electrical modules 140 in cabinet A that need to be connected to cabinet D are connected to the third electrical interface, and the third electrical interface is connected to cabinet D. It should be noted that when a large number of electrical modules 140 need to be connected to the same electrical interface 121, the connection of multiple electrical modules 140 between two cabinets 100 can also be achieved through two or more electrical interfaces 121; of course, when a small number of electrical modules 140 need to be connected to the same electrical interface 121, the connection of multiple electrical modules 140 between multiple cabinets 100 can also be achieved through one electrical interface 121.

[0043] It should be noted that when cabinet A and cabinet B of the existing combined cabinet in the machine room are connected, they are connected by wiring between the side terminals. When multiple electrical modules of cabinet A are connected to multiple electrical modules of cabinet B, multiple wiring and welding between the side terminals are required, which results in a lot of wiring between cabinets and a huge workload of cable laying and welding during construction. In the embodiment of the present invention, an interface layer 120 connected to the electrical module 140 is provided on the top of the cabinet 100. At the construction site, wiring connection between cabinets 100 can be achieved only through the interface layer 120, which greatly reduces the workload of on-site operations.

[0044] In one embodiment of the present invention, Figures 2 to 5 As shown, the mounting position 111 has a first mounting node 112 and a second mounting node 113 that match each other. The first mounting node 112 is used to connect with the electrical module 140 , and the second mounting node 113 is used to connect between the mounting positions 111 .

[0045] It can be understood that by arranging the first installation node 112 and the second installation node 113 at the installation position 111, the second installation node 113 between the inner layers of the cabinet is pre-wired and connected, and according to the use requirements of the module combination cabinet, the electrical module 140 is arranged at the installation position 111, and the connection between the electrical modules 140 can be achieved only by connecting the electrical module 140 to the first installation node 112.

[0046] Specifically, the first installation node 112 and the electrical module 140 can be connected in a plug-in manner, which is convenient for adjusting, increasing, and reducing the arrangement of the electrical module 140 in the cabinet 100, thereby facilitating the design of modular cabinets for various purposes.

[0047] The control device for rail transit provided in the embodiment of the present invention eliminates the side terminals of each layer of the existing combination cabinet, and leads from the second installation node 113 of one installation position 111 to the second installation node 113 of another installation position 111 through the internal wiring of the cabinet 100, so that the internal wiring design and circuit design of the module combination cabinet directly display the wiring nodes (the first installation node 112 and the second installation node 113), and when measurement or conduction is required, the nodes can be directly tested.

[0048] Further, such as Figure 1 and Figure 2 As shown, the bottom of the cabinet 100 has a zero layer 130 , which serves as a power supply introduction layer; the zero layer 130 has a plurality of power supply interfaces, which are correspondingly connected to the multi-layer electrical control layer 110 .

[0049] It can be understood that in the modular cabinet of this embodiment, the power supply is reordered, the head-to-tail ring connection mode of the power supply in the existing circuit is modified, and the bottom of the cabinet 100 is arranged with power supply interfaces corresponding to the multi-layer electrical control layer 110, so that the power supply of each electrical control layer 110 is led out separately, which is convenient for handling power supply mixed faults. It should be noted here that one electrical control layer 110 can be connected to one power supply interface, or one electrical control layer 110 can be connected to multiple power supply interfaces.

[0050] In one embodiment of the present invention, the plurality of module cabinets include a switch cabinet, a signal cabinet, and a track circuit cabinet, and the electrical modules 140 between the layers in the cabinet 100 are connected by cables 150 based on a signal interlocking relationship. For example, the cables are insulated copper core wires.

[0051] Among them, signal interlocking is to ensure the safety of railway station operation and shunting operations, and to establish a mutual restriction relationship between signal machines, turnouts and routes through technical means. The control equipment is mainly used to install electrical modules 140 such as relay combinations, power supply combinations and other electrical component equipment, and to connect indoor and outdoor signal equipment with cables to reflect the status of signal machines, turnouts, and track circuits, and control them through related operations, thereby controlling the operation of trains and shunting. Therefore, according to the three uses of signal machines, turnouts, and track circuits, the multiple module combination cabinets in this embodiment include turnout combination cabinets, signal machine combination cabinets, and track circuit combination cabinets.

[0052] In one embodiment of the present invention, the function of the switch combination cabinet is to reflect the direction of the outdoor switch and convert the direction of the associated switch according to the route requirements. The electrical module 140 in the switch combination cabinet is the first electrical module for controlling the switch.

[0053] Optionally, the turnout combination cabinet includes a cabinet 100, and the electrical module 140 in the cabinet 100 is used to control the switching of the turnouts at the five outdoor traction points and reflect their position states. For example, the cabinet 100 of the turnout combination cabinet is divided into 11 layers in the height direction, and the turnout combination cabinet can be installed with 11 layers of combinations.

[0054] The turnout combination cabinet includes 5 cabinets 100. The turnout combination cabinet uses a single-action turnout combination cabinet for each group of 5 traction point speed-up turnouts, or each group of double-action 5 traction point speed-up turnouts shares one (or two) turnout combination cabinets. The single-action turnout combination cabinet and the double-action turnout combination cabinet can be configured in a corresponding combination according to the existing design. For example, the combination arrangement of the 5 traction point turnout combination cabinets can be as shown in Table 1.

[0055] Table 1

[0056] The combination arrangement of the 5-traction point turnout combination cabinets can also be shown in Table 2.

[0057] Table 2

[0058] In Table 1 and Table 2, Z1, Z2, Z3, Z4 and Z5 represent 5 cabinets in the turnout combination cabinet respectively, Z6, Z7, Z8, Z9 and Z10 represent 5 cabinets in the turnout combination cabinet respectively, letters or letters plus numbers represent the combination name, for example, JK represents the interface layer, 103 represents turnout No. 103, 103 tip 1 represents the control combination of the first switch machine of the turnout point rail No. 103, 103 tip 2 represents the control combination of the second switch machine of the turnout point rail No. 103, 103 tip 3 represents the control combination of the third switch machine of the turnout point rail No. 103, 103 heart 1 represents the control combination of the first switch machine of the turnout heart rail No. 103, and 103 heart 2 represents the control combination of the second switch machine of the turnout heart rail No. 103; QB represents the turnout drive combination; JDF-S represents the double-action turnout auxiliary combination; JDF-D represents the single-action turnout auxiliary combination; DC5 represents the 5-wire turnout combination. It should be noted here that the meanings of the parameters related to 101, 102, 104, 105, 106, 107, 108, 109, and 110 in Table 1 and Table 2 are similar to those of 103, except that they represent different corresponding turnout numbers.

[0059] The electrical module 140 of the electrical control layer 110 in the cabinet 100 forms a turnout control combination, and the turnout combination cabinet is composed of a zero layer 130, a turnout control combination, and an interface layer 120. The layers are connected by cables based on a signal interlocking relationship; wherein, the zero layer 130 is used to connect the power supply outside and inside the cabinet 100; the turnout control combination is used to give the opening position of the corresponding turnout, and to convert the opening direction of the associated turnout according to the route requirements; the interface layer 120 uses cables to connect the equipment between cabinets.

[0060] It should be noted that the existing combination cabinets in the machine room adopt a mixed arrangement of signal combination and turnout combination, and the degree of standardization is low. However, the present embodiment arranges the signal and turnout in different cabinets, so as to design modular combination cabinets for various purposes based on the purpose, and the degree of standardization is high; in addition, the wiring between the cabinets 100 of the turnout combination cabinet directly matches the cabinet 100 with the wiring inside the cabinet that was originally transferred through the combination side, and the wiring between the cabinets 100 is uniformly led to the interface layer 120, and the wiring connection between the cabinets 100 is realized through the interface layer 120, which greatly reduces the transfer terminals and eliminates the possible fault points of the combination side terminals.

[0061] Furthermore, the module combination cabinet also includes a monitoring module and / or an alarm module arranged at the installation position 111 in the cabinet 100 .

[0062] Specifically, the monitoring module and the alarm module wiring are integrated into the modular cabinet at the same time, and the inter-cabinet wiring is led to the interface layer, so as to achieve one-time construction and avoid the need to dismantle and modify the wiring on site, thus meeting the requirements of "one map". For example, the alarm module is a fuse alarm circuit.

[0063] In one embodiment of the present invention, the function of the signal combination cabinet is to reflect the lighting status of the outdoor signal and perform lighting conversion according to the route requirements. Trains and shunting vehicles travel according to relevant lighting definitions. The electrical module 140 of the signal combination cabinet is the second electrical module for controlling the lighting status of the outdoor signal.

[0064] Optionally, the cabinet 100 of the signal combination cabinet is separated into 11 layers in the height direction, and each cabinet 100 of the signal combination cabinet can be installed with 11 layers of combination, and the signal combination cabinet includes two cabinets 100, and the electrical modules in the two cabinets 100 are respectively used to control the lighting state of the outdoor entry signal, the lighting state of the outdoor exit signal, and the lighting state of the outdoor shunting signal. It should be noted here that the two cabinets of the signal combination cabinet are located on both sides of the parking position along the driving direction.

[0065] For example, the combination cabinets in the existing machine room adopt a mixed arrangement of signal combination and switch combination, as shown in Table 3. The signal combination cabinet of this embodiment divides the signal combination placed in each combination cabinet in the existing design into combination cabinets according to the upper and lower throats of the station type, and arranges them in the order of entry-exit-shunting, as shown in Table 4.

[0068] In Table 3, Z11 to Z13 represent cabinets respectively, and in Table 4, Z14 and Z15 represent cabinets respectively. The combination name column uses letters to represent the combination name, and the purpose column uses letters and numbers to represent the signal name. For example, JK represents the interface layer; S1 represents the control combination of the exit signal of the up track 1, and correspondingly, SⅡ, SⅢ, S4, S5 are the control combinations of the exit signals of the up tracks Ⅱ, Ⅲ, 4, and 5 respectively; X1 represents the control combination of the exit signal of the down track 1, and XⅡ, XⅢ, X4, and X5 are the control combinations of the exit signals of the down tracks Ⅱ, Ⅲ, 4, and 5 respectively; KJX represents the control combination of the entrance signal of the passenger-dedicated line; KCX represents the control combination of the exit signal of the passenger-dedicated line; DX represents the control combination of the shunting signal; USU represents the control combination of lighting the yellow flashing yellow light; USUL represents the scattered control combination of lighting the yellow flashing yellow light; D in D102, D104, D106, and D108 represents the shunting signal, and the number represents the number of the shunting signal; X, XF, S, and SF represent the down track entrance signal, the down reverse entrance signal, the up track entrance signal, and the up reverse entrance signal respectively.

[0069] The electrical module 140 of the electrical control layer 110 in the cabinet 100 forms a signal light control combination, and the signal combination cabinet is composed of a zero layer 130, a signal light control combination, and an interface layer 120, and each layer is connected by cables based on a signal interlocking relationship; wherein, the zero layer 130 is used to connect the external and internal power supplies of the cabinet 100 of the signal combination cabinet; the signal light control combination is used to give the lighting status of the corresponding signal and convert the lighting status of the associated signal according to the route requirements; the interface layer 120 uses cables to connect the equipment between the cabinets. It should be noted here that the use of the interface layer 120 to replace the existing side terminals can reduce the relay contacts in the circuit, thereby reducing the fault points and facilitating fault finding.

[0070] For example, the interface layer wiring of the signal machine combination cabinet is shown in Table 5 below.
