Description

 High-speed railway track side function module redundancy automatic switching system {.}

The automatic switching system (hereinafter referred to as "switching machine") of the high speed railroad track function module applicable to the high speed railway and general railroad. This switching machine is an interlocking device (IXL: Interlocking, Hereinafter referred to as "IXL") A track control function module (TFM: Trackside FunctI / Onal Module (TFM)), which is a lower part of the system. ) And the line changer module (PM: Point Module, hereinafter referred to as "PM") make it possible to operate with redundancy (1st and 2nd system).

This transfer machine automatically waits when a fault occurs due to a system error or an external surge during operation of a UM or PM that controls the line side equipment that is directly connected to the safety of railway operation such as a track changer or a signal, and interfaces safety information. The switching time is stored and the monitoring time is stored together so that the cause can be traced by the time slot when a defect occurs, reducing the data loss that occurs during the existing communication using the RS485 communication module, and monitoring module. It is possible to collect the state information of the transfer machine using. It can be set to maintain the operating system (1st or 2nd system) which was in operation when the power of the transfer machine is turned off and restarted, so that the stable system is maintained to improve the reliability of train safety operation and Improve convenience

In general, as illustrated in FIG. 1, a train control system (TCS) is generally classified into an automatic train control (ATC) 2 and a centralized traffic control (CTC) 3. And the interlocking device (4), each device is connected to each other by a communication network.

Here, the interlock device, which is a sub-system of the train control system, is installed in the station's machine room, the interlocking machine room (IEC), and the outdoor equipment box (OT), which is a central level (CL) and a site level (LL). ), And track side function module of track side level (TL).

The interlocking logic unit (electronic interlocking device), which is the central level of the interlocking device, is designed to safely and accurately operate the train by interworking a signal and a line changer, so as to safely operate the train. The track side function module of the track side level controls the direction of the track changer according to the command of the interlocking logic unit to compose the course of the train and to control the signal manifestation of the signal to express the driving conditions (stop, progress, etc.) to the train driver. Facility.

The line side function module of the line side level constitutes a communication network by an electric data link module (EDLM) or an optical data link module (ODLM), and can control up to 6 information processing modules for each data link module. .

However, the line side function module included in the interlocking device is composed of a single system and has a DC or AC input / output characteristic as a control target by one module, and has an input / output error detection function, but no countermeasure against module failure is provided. Since there is a problem that can not cope with the module failure, there is a problem to stop the train unconditionally for the safety of train operation when the module failure occurs, which causes a lot of inconvenience.

In order to improve this problem, multiple transfer function modules are used so that when a failure occurs in one function module, automatic transfer is made to another module. This is disclosed in Korean Patent No. 10-0673535.

Figure 2a is a configuration diagram of a switching system according to the multiplexing information processing module (line side functional module) of the train tracks according to the prior art, as shown in this, in communication with the central control processor of the track side, the information processing module ( M1, ..., Mn), transfer control module, Tx / Rx Driver Module, and power supply module.

The information processing module (M1, ..., Mn) is a device that performs interworking by an electrical or mechanical method, such as a signal, a line changer, etc. in order to support smooth train operation in the station yard of the track side, one module failure It is configured in a multiplexed state so that a switchover to another normal module can be made. The transfer control module is configured to determine whether there is an abnormality by real-time monitoring the status of the information processing modules (M1, ..., Mn) of the multiplexed line side, and the automatic switching to the information processing module of the normal state by the result, It includes a control unit (CPU Module), an switching unit (Isolat I / On I / O Select I / On Module), a communication control unit (Protocol Driver), a network address setting unit (Configure Module), and a display unit (LED Driver). The control unit is configured to compare and analyze command messages from the data link module DLM to determine whether the multiplexed information processing modules M1, ..., Mn have failed. The transfer control module is configured to connect the data processing module (M1, ..., Mn) and the data link module of the multiplexed line side to each other, and includes a reception buffer (Rx Buffer), a transmission buffer (Tx Buffer), and a path selector. .

The transfer system according to the multiplexing of the information processing module for train tracks according to the prior art configured as described above is to perform automatic switching to a normal information processing module after multiplexing the track information processing module.

However, the switching system according to the multiplexing function of the railroad side function module according to the above technology is a system error after the field installation, or when the power of the switching system is turned off, an electronic interlocking device, a signal system, signals, and a line switch, And communication interface with the terminal device such as Train DetectI / On, which affects the communication between the interlocking device and the line-side functional module, resulting in the interruption of train operation. The same problem may arise.

In order to solve such a problem, Patent No. 10-1340080 discloses the first and the first to maintain a communication interface as a main system when a defect occurs and a power cut is detected in a switching system (automatic switch) as shown in FIG. 2B. And a third relay and a fourth relay for connecting an input / output control signal between the main relay and the line termination device as a relay control signal of the switching system is generated. If it is determined that a fault has occurred, it automatically switches to bypass the communication path between the data link module, the line side function module and the last input / output terminal to communicate with the main line side function module. Communication interface due to faulty function module of spare system line, defect of automatic switch, removal of automatic switch or defective power supply It was to prevent the device being blocked.

However, this is a solution only when the automatic changer is a problem. When the automatic changer fails, it is unconditionally transferred to the main line (1 system), and when the line side function module of the main line is in an error state, it leads to a system failure, which hinders train operation.

In a similar patent, Korean Patent Publication No. 10-1210930, as shown in Figure 2c, monitors the power supply state and the signal transmission state of the transfer control module, and according to whether or not to block the communication path through the multiple communication module, By bypassing the existing communication interface of the central control processing unit and the selected line edge function module, the communication interface between the electronic interlocking device, which is the upper system, and the line side function module, can be maintained as the previously selected interface path without unconditionally switching to the first system. It provides a solution.

However, when the switching system is restarted as shown in FIG. 2C, the switching system is unconditionally switched to the first system and is maintained as the first system when the switching system fails. There is a problem that can cause. Both systems can not select the operating system in the field in the event of a switching system failure, thereby worsening the hassle to check and replace the system downtime due to replacement of the functional module on the track side.

In addition, in the method of specifying the switch ID and address, although the ID and address of the line side function module linked to the switch is constant, an unnecessary network address setting unit is added in FIG. 2A, and ID and address are shown in FIG. 2C. Instead of deleting the hardware to be set, it is shown that the software detects the ID and address information transmitted from the line side function module through communication. If the communication status of the switching system is unstable, it may cause a problem in ID and address recognition. have.

In addition, all of the above devised solutions are relatively large in noise due to the expansion of the existing current loop method, which is fundamentally an error source because communication errors occur not only in the switch module but also in the line side function module. There is a problem that countermeasures against errors cannot be solved without removing the in noise. After all, without stabilizing the communication system, there is no limit to establishing a countermeasure against the system.

On the other hand, in the prior art as described above, the absence of visual information of the switching system and the absence of state information storage function, it is difficult to determine the cause, such as the switching time when the error of the line side function module and switching system.

In order to improve the problems of the prior art as described above, the present invention stores various states required for communication, such as a switching state, in NVRAM (Non-volatile memory) to operate stably even when restarting after power-off of the switching machine. The purpose is to maintain a stable connection to the operating system (first or second system).

Also, in case of switching system failure, it is possible to set the operating system manually in the machine room (on-site) by attaching the automatic / manual selection switch and the first / second selection switch on the front of the changer module. Allows quick manual selection.

In addition, instead of the existing current loop method, the noise problem caused by the expansion of the current loop method is used to convert the RS485 communication optimized for multiplexing to significantly improve the noise problem.

In addition, an object of the present invention is to add a clock function to the switch and to store the log data for a certain period of time by mounting a memory module to easily back up the cause of the error situation when the problem occurs.

In the train control system according to an embodiment of the present invention will be described in detail with reference to Figures 3 to 7 attached to the automatic switching device to the main relay using a relay.

Data link module and lower system, which is the upper system of electronic interlocking device linked by control of train control system, use RS485 communication and RS485 converter instead of current loop and Manchester code method to communicate the line between function module. Reduces data loss during loop and Manchester code multiplexing. The change of this communication method can maximize the effect when the data link module and the line side function module are replaced at once.

If the existing data link module is already used in the field, it is necessary to change the current loop and manter code transmitted from the data link module to 485 and UART communication using the converter module. Similarly, if the line side functional module uses the existing current loop method, a converter module that converts the 485 signal into the current loop and manter code method is required.

3 and 4 are block diagrams of the interface of the universal module changer and the line changer module changer according to an embodiment of the present invention.

The general-purpose module changer checks the status messages of the dual-sided line side function modules 1 and 2 (TFM (Trackside FunctI / Onal Module) → SSI) status bit to determine whether there is an error and automatically switches the system according to the status. It has a function to maintain only the output of the module selected from the duplexed line side function module.

The general-purpose changer receives the control command transmitted from the electronic interlocking device (SSI) and continuously checks the status information of the first and second line side functional modules that activate or stop the output according to the command.

If there is a failure (bit information 0) in the transmission message status information of the duplicated line edge function module, the line side function module changer automatically switches to a system in which the input / output state information is normal (bit information 1). If the status information is checked for failure in both the dual-sided line side function modules 1 and 2, the line side function module reports the status to the electronic interlocking device.

As shown in Fig. 3, the input of the general-purpose module changer inputs one module internal circuit power 48VDC, one 24VDC for output power supply, an optical data link module (SOLDLM) or an electrical data link module (EDLM) (ELDM). Consists of two connected current loop links (one per data link), and the output is the current connected by eight 24VDC power supply for the first and second line-side functional module outputs, an optical data link module or an electrical data link module (EDLM). It consists of two loop links (one per data link) and one EIA-485 serial link to be used for the changeover test.

One 48V DC power supply (maximum ripple voltage: 10%) is required for the internal electrical circuit of the switch module of the line side, and the voltage limit is 40V ~ 70V including the ripple voltage. Is 10 VA or less. The module must be reset when the 48V DC power supply is interrupted.

In the input / output of the general-purpose module changer, the input is connected to the equipment from inside or outside the module and maintains the hot-standby state by providing a common input to the dual-sided line side function module. In addition, the output load depends on the output load of the line side function module, and the output maximum load is 8W, and maintains the output of the selected line side function module.

As shown in Fig. 4, the input of the line changer changer includes one 48VDC internal module power supply, two current loop links (one per data link) connected to an optical data link module or an electric data link module (EDLM), and 3 for the line changer output. 1 phase power 380 ~ 400VAC, 1 PPD power 48V DC for line converter, 4 pairs of inputs for pointer detection (+/-)

4 x 3-phase 380 to 400 VAC power supply for 1- and 2-phase select outputs, 2 current loop links (1 per data link) to optical data link module or electrical data link module (EDLM), line switch module It consists of one EIA-485 serial link used for the switchover test and four pairs of outputs (+/-) for point detection.

5 is a communication and control signal flow diagram of the companion device according to an embodiment of the present invention.

The conversion circuit from the current loop type to RS485 type is the same as the line side function module type.

In the line changer module changer 200, both the system power source and the I / O power source use DC48V, and the I / O power source senses the direction of the input power source and the output power in which direction the line converter motor is designated. Actually, the motor power that drives the line changer is a three-phase AC380V supplied internally, and the motor controlling the line changer at one point consists of a set of four channels.

FIG. 6 is a block diagram illustrating a switch communication and control signal flow diagram according to an exemplary embodiment of the present invention. Referring to FIG. 6, a communication interface between a data link module of an electronic interlocking device and a line side termination device of a train is maintained. In the redundant automatic switching system of the high speed railway track side function module for real-time monitoring and maintaining communication of the line side function module multiplexed in the system and the second system and the switch module for automatic switching thereof, the control signal is received from the data link module 10. A communication distribution unit (110) for distributing the first and second line function modules (20a, 20b); A communication selector 120 for selecting a signal input to the first and second line function modules 20a and 20b; The line side function module 1 and 2

An output selector 130 for selecting a signal input from the systems 20a and 20b and outputting the signal to the line edge equipment; And an input distribution unit 140 for inputting signals input from the line edge input unit to the line edge function modules 1 and 2 (20a and 20b), respectively.

In addition, Figure 7 is to monitor and maintain the communication in real time to the line switch module multiplexed to the first and second systems and the switch module for automatic switching to maintain the communication interface of the data link module of the electronic linkage device and the train switching period of the train In the high-speed railway track side functional module redundant automatic switching system, Communication distribution unit 210 for receiving a control signal from the data link module 10 and distributes to the line switching module module 1 and 2 (40a, 40b); A communication selector 220 for selecting a signal input to the first and second line switch modules 40a and 40b; An output selector 230 for selecting a signal input from the first and second line switch modules 40a and 40b and outputting the signal to the line switch output unit; And an input distribution unit 240 for inputting a signal input from the line switch input unit 50b to the line switch module first system and the second system 40a and 40b, respectively.

Here, the track side function module is a device that performs interworking by electric or mechanical methods such as signal and line changers in order to support smooth train operation in the station yard of the track side. It is configured in a multi-system state so that the switching can be made, as shown in Fig. 5 is separated into a switch module as the line function module (20a) and the line converter module 40a, each used differently.

The communication distributor 210 receives a control signal from the data link module 10 and distributes the control signal to the first and second lines 40a and 40b. That is, it divides the signal coming in as one signal from the data link module into the line side function module 1st, 2nd system and switcher module. In the current current loop method, each circuit is configured to compensate for the current, but when converted to RS485, it can be expanded to 32 basic devices, thus eliminating the need for a circuit.

The communication selector 220 is a device for selecting a signal input to the line switch module first system and second system 40a, 40b. That is, the communication selecting unit 220 is a circuit that selects one of the signals coming from the first and second line function modules and transmits it to the data link module. Therefore, only one signal must be transmitted even if the current loop method is converted to the RS485 method. It includes a selection circuit that delivers the signal of the currently selected system.

The switch module 250 receives the control command signal transmitted from the central processing unit 300 of the SSI to the line edge output unit, and activates or stops the output line function module according to the command. And status information of the second system is continuously inspected. The inspection uses the status information and ID and address information between the SSI and the line side functional module. The ID and address information prevents an inconsistency between the SSI and the line side functional module communication. do.

For example, inconsistency is the transmission and reception data of the first and second systems, the R network and the S network, which should be the same, is incorrect due to a communication error. The main causes are mainly interference from wiring, leakage of current, and noise from power supply. Therefore, this can be prevented by using mutual ID and address information.

In another embodiment of the present invention, ID and address information is stored in NVRAM. In other words, once the switching status is saved and the data link module and the line side function module communicate, it is more stable than changing randomly to operate the system that was operated stably when the switch is turned off and then on again. Is safe in In order to maintain stable communication, the ID and address are stored in the system's built-in NVRAM. Even if the ID and the address value are broken due to the broken data, if the original ID and the address value are retained, an erroneous malfunction can be prevented. In the past, ID and address values were stored in a hardware board called CONFIG card, but there was an inconvenience of changing them with a dip switch every time the system was changed. The method of storing the ID and address in NVRAM stores the ID and address of the incoming line side function module for a predetermined time immediately after the NVRAM initialization.

The input distribution unit of the present invention is provided with a function of directly connecting the signal of the line side input unit to the line side function module 1 system and the 2 system under control. If there is a failure (status information 0) in the transmission message status information of the duplicated line side function module, the line side function module changer automatically switches to the system where the input / output state information is normal (bit information 1). If the status information of the dual-sided line side function module 1 and 2 is checked as fault, the line side function module keeps the existing selected line side function module and reports the state to the electronic interlocking device.

The line changeover switch has a function of determining whether there is an error by checking the status message of the dual-stage line changer module system 1 and 2 (TFM → SSI), and automatically switching according to the state. It also plays a role of maintaining only the output of the selected module from the duplexed line converter module module. The line changer changer 200 receives the control command transmitted from the central processing unit 300 and continuously checks the state information of the line changer modules 1 and 2 to operate or stop the output according to the command. The inspection uses status information and ID and address information between the SSI 300 and the line changer module changer 200. The ID and address information are inconsistencies in the communication between the SSI 300 and the line changer module changer 200. To prevent. Operation of the line changer switch 200 as described above has the effect of increasing the system availability by maintaining the stable system to maintain the existing state when the switch power is restarted (Off) after restart (Off).

If there is a failure (bit information 0) in the transmission message status information of the doubled line changer module changer 200, the line changer module changer 200 automatically switches to a system in which the input / output state information is normal (bit information 1). .

If the status information is checked as a fault in both the dual-stage switch module module 1 and 2 system, the line switch module switcher 200 maintains the state of the existing link switch module switcher 200 and the electronic linkage device ( SSI). The operation of the system as described above has the effect of increasing the system availability by maintaining the stable system to maintain the existing state when the power of the line changer module changer 200 is restarted after the off (Off).

The high speed rail track function module redundancy automatic switching system of the present invention is equipped with a monitoring device, so that the time for monitoring is stored together so that the data stored in the event of a defect due to a system error, external surge occurrence, etc. can be stored in the memory device. The cause can be analyzed by time slot.

For example, the high-speed rail line function module redundant automatic switching system allows the state information to be stored together with time so that the data can be backed up to the memory device in case of a defect caused by systemic errors or external surges. It is equipped with time and storage to facilitate this.

Data stored in the memory device can be backed up by USB for analysis, and the above functions are recorded for each time zone for monitoring. Therefore, if a fault occurs due to an internal situation or an external factor of the system, the cause is accurately identified and countermeasured. There is an advantage to establish.

In the present invention, the automatic switching system of the redundant high speed rail line function module has a current between the data link module 10 and the communication distribution unit 110 and 210 and the communication selection unit 120 and 220 to increase the transmission and reception accuracy and enhance the processing function. A converter for converting the loop method to the RS485 communication method and a converter for converting the RS485 communication method to the current loop method are provided to reduce the communication error between the switchers 100 and 200 and the data link. In other words, as described above, the stability of the current loop method is multiplexed to stabilize the noise by changing the state vulnerable to noise to the RS 485 method that is strong for multiple communication.

The configuration as described above can be easily monitored from the outside by adding a memory module to the switcher (100, 200) and by adding the maintenance communication port using RS485 communication to enable real-time monitoring on the front of the switchboard Provides maintenance efficiency

In the high-speed railway line functional module redundant automatic switching system of the present invention, the method of designating the ID address of the switcher reads a predetermined number of IDs and addresses, selects a maximum value, and once specified, stores it in a nonvolatile memory to be initialized from the next time. Until now, the ID and address are stored. In other words, the cumbersome address setting unit (CONFIGURATI / ON card) is unnecessary, the ID and address can be set immediately with the communication, and the problem of the CONFIGURATI / ON card recognition problem or communication failure caused by the conventional invention is caused. Problems can be solved when it is difficult to grasp.

Automatic changeover is made by module, and it has the scalability to provide intelligent changeover function through changeover status monitoring by transmitting data from the changer maintenance device to big data server and AI server.

In accordance with an embodiment of the present invention, a memory module is mounted in a changer to store log data for a predetermined period of time, and when a problem occurs, the memory module is detachable memory (USB memory, SD) so that the cause of the error situation can be easily analyzed. Card, etc.), or detachable, but it is configured as a built-in memory that can send data to the external backup device by sending a command by communication.

On the front of the changer, there is a maintenance communication port of RS485 communication for real-time monitoring of the changer status. Connecting multiple switch maintenance communication ports to one control device (PC), the control device becomes a log data server of the plurality of switchgear maintenance devices when the control device responds to a command via a unique address. When the server stores data for a long time, it becomes log data that can determine the error occurrence situation or trend. The log data server may provide an intelligent transfer function by monitoring data of the transfer state by transmitting data to the artificial intelligence server. For long term data acquisition, you can use the 485 debug communication port on the front of the changer, but connect it to the rear terminal block through the motherboard.

The current loop signal transmitted from two electric data link modules (EDLM) networks (R and S) is converted into a RS485 signal from a CL-RS485 converter to an RS485 signal and transmitted to a transfer device. 40a).

The line side function modules 20a and 40a communicate with each other in the current loop mode, and immediately before the input of the line side function module, the RS485 signal is converted back to the current loop type using the RS485-CL converter.

On the contrary, the current loop signal output from the line side function modules 20a and 40a is converted into an RS485 signal via the CL-RS485 converter and transferred to the transfer device and the data link module.

In the current loop method, TX and RX are separated, but RS485 is integrated with TX and RX and can be connected to multiple devices.

Therefore, RS485 signal line combines RX and TX in R network by integrating RS485 line which is transmitted / received by data link module, TFM1, TFM2, and switcher into one R network. Similarly, RX and TX are integrated in S network to connect RS485 lines to data link module, TFM1 and TFM2 in one S network.

Converter that converts current loop to RS485 signal has to process input and output at the same time, so there are 1 channel to convert current loop input to RS485 and 1 channel to convert RS485 input to current loop.

System power supply and I / O power supply are separated so that communication is not affected even if I / O power problem occurs. The line side function module uses DC48V for system power and 24V for I / O power.

In addition, the high-speed railway track side functional module redundant automatic switching system is provided with an interface port for maintenance and remote monitoring.
