Description

Technical Field

[0001] This invention relates to the field of railway signal coding technology, specifically to a modular railway signal coding design method and system. Background Technology

[0002] Railway signal coding is an important technical means of transmitting train operation information to trains using railway signaling equipment. It achieves the transmission of train operation control information by superimposing frequency-coded signals on track circuits. Coding design is an important part of railway signaling engineering design, involving multiple aspects such as the selection and layout of coding equipment, circuit design, and wiring design.

[0003] Currently, the design of railway station signal coding mainly relies on manual methods. Designers need to consult a large number of standard drawings and technical documents based on the specific conditions of the station, and manually draw design documents such as coding equipment layout lists, circuit diagrams, and wiring diagrams. This traditional design method has the following problems:

[0004] (1) Large workload: The design of electronic code involves multiple equipment models, multiple electronic code methods, and multiple track processing methods. Each situation corresponds to different design drawings, and designers need to handle a large amount of drawing work.

[0005] (2) Poor accuracy: Manual design is prone to omissions and errors, especially in the process of dealing with complex coding circuits and internal wiring. Slight negligence can lead to design errors, affecting engineering quality and driving safety.

[0006] (3) Low standardization: Different designers have different design habits and styles, resulting in a diversity of design drawings, which is not conducive to the accumulation and reuse of design results, nor to construction and maintenance.

[0007] (4) Inefficiency: Manual design has a long cycle and is difficult to adapt to the needs of rapid development of railway construction. In particular, the design efficiency problem is more prominent in situations such as station renovation and emergency rescue.

[0008] Therefore, there is an urgent need for a standardized and modular coded design method that can automatically complete the coded design based on station parameters, thereby improving design efficiency and accuracy. Summary of the Invention

[0071] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the invention. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present invention are not shown or described in the specification. This is to avoid obscuring the core parts of the invention with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0072] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0073] The first embodiment of the present invention provides a modular railway signal coding design method, such as... Figure 1 As shown, the detailed steps of the method of the present invention are as follows.

[0074] like Figure 1 As shown, in step S100, a standard library for railway station signal coding system is established. The standard library for coding system includes a library of different types of coding equipment models, a library of outdoor coding methods, and a library of coding mainline track processing methods.

[0075] The above steps specifically include:

[0076] S110. Establish a standard database of coded equipment models. Obtain model information for coded equipment from different manufacturers, including ZPW-2000A from CRSC, ZPW-2000G from Gu'an, ZPW-2000R from Ruixing, and ZPW-2000S from Hollysys. Different models of coded equipment differ in frequency shift cabinet layout, transmitter circuits, and encoding circuits, requiring the establishment of separate standard modules.

[0077] S120. Establish a standard library for outdoor signaling methods. Obtain the types of outdoor signaling methods, including two-wire signaling, four-wire signaling (signaling), four-wire signaling (electric rail), integrated track circuits, and non-signaling. Different signaling methods correspond to different combination types, wiring methods, and equipment configurations. Two-wire signaling combinations include the NFL lightning protection combination, ZPW-TFGZ combination, MGL-F combination, and MGL-R combination; four-wire signaling combinations include the MGFL2-U combination; four-wire electric rail combinations include the ZBPU-T combination and the ZDTR-T combination.

[0078] S130. Establish a standard library of coded mainline track processing methods. Obtain the coded mainline track processing method library, including two processing methods: merging mainline tracks and receiving / departure routes, and separating mainline tracks and receiving / departure routes. When tracks are merged, the receiving route and the departure route share a transmitter; when tracks are separated, the mainline track has a separate transmitter, and the receiving route and the departure route each have their own transmitter.

[0079] S140. Establish a standard library of transmitter standby types. Obtain transmitter standby types, including relay codes (1+1) and relay codes (N+1). In the 1+1 standby mode, each transmitter is configured with one standby transmitter; in the N+1 standby mode, multiple transmitters share one standby transmitter.

[0080] like Figure 1 As shown, in step S200, a standard library of coded equipment arrangement list modules is established. The standard library of coded equipment arrangement list modules includes standard arrangement list modules for frequency shift cabinet structure, integrated cabinet structure and combined cabinet structure.

[0081] The above steps specifically include:

[0082] S210. Establish standard modules for frequency shift cabinet structure. Taking ZPW-2000A coded (1+1) and ZPW-2000G (1+1) as examples, such as... Figure 2 As shown, the frequency shift cabinet structure consists of three parts: a zero layer, main and backup transmitters, and attenuators. There are two transmitter layers, each capable of housing five transmitters. The layout principle is as follows: downlink and downlink outbound track coded transmitters are placed at positions 1FS, 3FS, 5FS, 7FS, and 9FS on the transmitter layer; uplink and uplink outbound track coded transmitters are placed at positions 2FS, 4FS, 6FS, 8FS, and 10FS on the transmitter layer. If a downlink or uplink transmitter cannot be placed on this layer, it can be placed on the uplink or downlink layer if space is available, thus reducing the number of frequency shift cabinets. The sequence is: forward train reception, forward train departure, reverse train reception, reverse train departure, approach rail, track. The N+1 backup transmitter is placed at position 9 or 10 of the last frequency shift cabinet, with position 9 having priority.

[0083] S220. Establish standard modules for modular cabinet structures. For example... Figure 3 As shown, the cabinet has 10 layers, and each layer can hold one unit.

[0084] S230, Establish standard modules for the integrated cabinet structure. For example... Figure 4 As shown, the two-wire coded combinations are NFL (36), NFL (20), ZPW-TFGZ, MGL-F, and MGL-R. Each NFL column has 20 or 36 lightning protection devices. The track name indicates the sending end, and the track name J indicates the receiving end. Lightning protection devices are required for both the sending and receiving ends of all coded sections and protected sections. The lightning protection combination is generally set at the top layer. The ZPW-TFGZ combination occupies one column, with 6 devices per column. One device is set for each transmitter in each frequency shift cabinet, which is a one-to-one correspondence. It is set after the NFL combination. Each MGL-F (track section transmitting segment) column has 3 devices, and each MGL-R (track section receiving end) column has 5 devices. If they can be placed in one combination cabinet, the MGL-F position is arranged first, followed by the MGL-R position. If they cannot be placed in one combination cabinet, the MGL-F and MGL-R are set separately.

[0085] like Figure 1 As shown, in step S300, a standard library of coded station circuit modules is established, which includes a code-issuing circuit module, an encoding circuit module, and a scattered circuit module.

[0086] The above steps specifically include:

[0087] S310, Establish the code transmission circuit module. For example... Figure 5 As shown, the coding circuit consists of: an indoor isolator + a transmission relay + a transmitting regulator circuit + a transmitter circuit + an encoding circuit. The indoor isolator is selected based on the equipment type: for two-wire coding, the sending / receiving end is selected based on the track markings in the diagram or the coding route engineering table; for four-wire signaling, the sending / receiving end is selected based on the DM combination arrangement; for four-wire electric rail, the sending / receiving end is selected based on the DM combination arrangement. There are two models of transmitting regulators: signaling (ZPW-TFGZ) and electric rail (ZBPU-T). The transmitter circuit is mainly divided into ZPW-2000A and ZPW-2000G models. Each type is divided into merged track and separate track types. Each type has six variations based on its applicable type, and each type includes different coding patterns.

[0088] S320, Establish the encoding circuit module. For example... Figure 6As shown, the encoding circuit is mainly divided into mainline encoding (ZXJM), FM encoding, reverse encoding (FXJM), and track encoding (GD). ZXJM encoding is further divided into multiple sub-modules (ZXBM11~ZXBM31) based on the number of signal points between two stations and the lateral route of turnout No. 18; FM encoding is also divided into multiple sub-modules based on the number of signal points between two stations and the lateral route of turnout No. 18; FXJM encoding is also divided into multiple sub-modules based on the number of signal points between two stations and the lateral route of turnout No. 18; GD encoding includes siding track encoding and mainline track encoding. Each encoding module forms a standard combination relationship with its corresponding transmitter circuit module, such as ZXBM11 corresponding to transmitter circuits 03100 / 03200 / 03110 / 03210, and ZXBM12 corresponding to transmitter circuits 03101 / 03201 / 03111 / 03211, etc.

[0089] S330. Establish scattered circuit modules. This includes the JMJ / FMJ excitation circuit module and the GCJ excitation circuit module. The DM1 combination is used to arrange the mainline train receiving route. When the track is not divided, DM118~DM112 are selected, and when the track is divided, DM128~DM114 are selected. The DM2 combination is used to arrange the departure route, and DM27~DM22 are selected. The DM4 combination is used to arrange the track turnout route, and DM48~DM42 are selected.

[0090] like Figure 1 As shown, in step S400, a wiring standard library is established, which includes a distribution panel module and an interlocking related relay wiring module.

[0091] like Figure 1 As shown, in step S500, a standard library of combined internal wiring modules is established, which contains combined internal wiring modules of different types.

[0092] The above steps specifically include:

[0093] S510. Establish the DM1 combination module. Arrange the mainline train receiving routes in the order of X, XF, S, SF, and the track names in the order from the track to the station signal. If the track is not divided, and there are fewer than 8 track sections (including track sections), select the internal coded combination wiring diagram (DM118~DM112) according to the actual sections; if the track is divided, and there are fewer than 8 track sections (including track sections), select the internal coded combination wiring diagram (DM128~DM124) according to the actual sections.

[0094] S520. Establish the DM2 combination module. Arrange the departure routes in the order of X and S, and arrange the track names in the order from the track to the entry signal. When there are fewer than 7 track sections (including track sections), select the internal coded combination wiring diagram (DM27~DM22) according to the actual sections.

[0095] S530. Establish the DM4 combination module. Arrange the turnout routes in the track, with the track names arranged in reverse order from the direction of travel. When there are fewer than 8 track sections (including track sections), select the internal coded combination wiring diagram (DM418~DM413) according to the actual section.

[0096] S540. Establish the ZXBM combined module. It includes several sub-modules from ZXBM11 to ZXBM31: ZXBM11 is suitable for two stations with two or more signal points, where forward departures do not involve a lateral route via turnout 18; ZXBM12 is suitable for two stations with two or more signal points, where forward departures involve a lateral route via turnout 18; ZXBM21 is suitable for two stations with one signal point, where forward departures and receiving at the other station do not involve a lateral route via turnout 18; ZXBM22 is suitable for two stations with one signal point, where forward departures involve a lateral route via turnout 18. The following are applicable to different types of train routes: ZXBM23 (for trains departing from one station and receiving trains at the other station via a lateral route through turnout 18), ZXBM24 (for trains departing from one station and receiving trains at the other station via a lateral route through turnout 18), ZXBM31 (for trains departing from one station and receiving trains at the other station via a lateral route through turnout 18), and ZXBM31+USUJF (for trains departing from one station and receiving trains at the other station via a lateral route through turnout 18).

[0097] S550, Establish the JZDMH combination module. Used for the approach section coding of semi-automatic block signaling. When the receiving direction does not pass through the lateral direction of turnout No. 18, each signaling station is equipped with LXJF, YXJF, ZXJF, TXJF, and CZ()LXJF relays; when passing through the lateral direction of turnout No. 18, an additional USUJF relay is added.

[0098] S560. Establish LXJF combination modules. LXJF1 is suitable for siding track coding, containing 10 LXJFs. When not connected to the main line, each departure or departure route signal is equipped with one LXJF relay. LXJF2 is suitable for reverse coding on the main line, connected to the main line, and the departure direction does not pass through the lateral direction of turnout No. 18. Each departure or departure route signal is equipped with one LXJF and one ZTJ relay. LXJF3 is suitable for reverse coding on the main line, connected to the main line, and the departure direction passes through the lateral direction of turnout No. 18. Each departure or departure route signal is equipped with one LXJF, one ZTJ, and one USUJ relay.

[0099] S570. Establish the GJF combination module. Used for track relay arrangement; when the track is not segmented, the first relay is placed in the main track section. When there are more than 8 coded route sections containing down / up tracks, the number of GJF combinations corresponds to the number of receiving routes; when there are less than 8 coded route sections containing down / up tracks, the number of GJF combinations corresponds to the number of down / up tracks.

[0100] S580. Establish the FBJ combination module. Used for arranging the code-generating alarm relays. One FBJ relay is set for each coded path. Each FBJ combination can hold 8 relays. The first FBJ combination should be set with +1FBJ and ZYBJ relays.

[0101] Figure 7 This is the internal wiring diagram of the NFL ensemble.

[0102] like Figure 1 As shown, in step S600, the correspondence between the interlocking signals, track circuits, and junction boxes related to the coded signaling is determined.

[0103] The above steps specifically include:

[0104] S610. Determine the correspondence between the coded routes and interlocking signals. The coded train receiving route starts from the entry signal or route signal and ends at the end of the receiving line where all switches are straight tracks. It is usually named after the entry signal, such as XJM, XFJM, SJM, SFJM. The coded train departure route starts from the exit signal or departure route signal and ends at the end of the departure line where all switches are straight tracks. It is usually named by the up or down track, such as XFM, SFM. The siding tracks are named after the exit signal, such as S3, X3, S4, X4. The mainline tracks are named after the exit signal, such as SI, XI, SII, XII.

[0105] S620. Determine the correspondence between the coded sections and the track circuit. This includes the sequence number of the track section in the route, the type of the coded end and track endpoint (for integrated track circuits, this is power supply and power receiving; for 25-cycle track circuits, this is coded power supply, coded power receiving, non-coded power supply, and non-coded power receiving), frequency, adjacent ends, and adjacent protection sections.

[0106] S630. Determine the correspondence between the coded sections and the distribution panels. For two-wire coded sections, the power supply cable and the power receiving cable are each assigned to a separate distribution panel. For four-wire coded sections, the power supply cable cores are assigned separately, and the power receiving cable is assigned separately to a separate distribution panel. For non-coded sections, the power supply cable cores are connected in parallel, and the power receiving cable is assigned separately to a separate distribution panel.

[0107] like Figure 1As shown, in step S700, based on the established standard library and corresponding relationships, the corresponding modules are automatically combined and called according to the coded parameters of the station to be designed, so as to realize the automatic design of coded drawings.

[0108] The above steps specifically include:

[0109] S710. Obtain the coded parameters of the station to be designed, including the coded equipment model, coded method, mainline track processing method, and coded route data (route name, starting signal, terminal signal, track section list, etc.).

[0110] S720: Based on the coded parameters, match and call the corresponding device arrangement list module, circuit module, wiring module and combined internal wiring module from the standard library.

[0111] S730. Arrange the equipment arrangement list module according to the design principle of the arrangement list module; automatically fill the equipment arrangement position into the equipment position in the coded circuit module, and combine the modules to generate a complete coded design drawing;

[0112] S740. Based on the module connection relationship in the circuit diagram and in accordance with the wiring connection principle, automatically generate the wiring connection relationship information to generate the wiring diagram of the circuit diagram.
