Description

Description: TECHNICAL FIELD [0001] The present invention relates to an information transfer controlling apparatus for railway vehicles,

The present invention relates to an information transmission apparatus for a railway vehicle, and more particularly, to a railway vehicle information transmission apparatus for converting a vehicle information collected by a sensor, a terminal apparatus, etc., into a standardized standard, To the information transmission device of the railway car.

A control system necessary for safe operation is applied to a railway vehicle that travels along a predetermined track such as a train or a subway. Such a control system is a system in which information collected through various sensors and terminal devices installed on a railway car is used for safe operation of the railway vehicle It is used as information necessary to establish countermeasures in case of an accident.

However, in relation to the running of the railway vehicle, since each constituent device is separately constructed and operated independently according to various technical fields such as a signal, a vehicle, and a facility as in the prior art 1 (Korean Patent Registration No. 10-0991633) The types of information processed by the constituent devices of the respective devices are different from each other. Therefore, even if the control system receives the above information in real time, it can be said that a considerable amount of time is involved in analyzing all the information, and it has been a problem that it is difficult to positively cope with the breakdown of the railway vehicle due to the time delay . In other words, even though the information transmitted in real-time, it took a considerable time to integrate / analyze it, so it could not detect and prevent the accident risk in advance.

In addition, the information generated in railway vehicles is very diverse, and the amount of data is small. Therefore, even if the data transmission from the railway car to the control center is performed in real time, the transmission delay time of the data actually occurs, so that there is a problem that the real time performance and reliability are inferior. This problem is caused by the fact that a large amount of data is actually transmitted through any one of the communication networks.

Also, when data is transmitted through one communication network, data may not be transmitted due to a connection error of the communication network. In such a case, the collected data may be omitted or deleted.

Prior art 2 (Korean Patent Laid-open Publication No. 10-2010-0083043) proposes a solution using RFID tags, however, in the prior art 2, an RFID tag is installed along a track, There is a disadvantage that installation, operation and maintenance costs are not so low because an RFID reader is required to be installed.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a railway vehicle information collection system for collecting railway car information, which is distributed and monitored by different sectors and functions, And a transmission device.

It is another object of the present invention to provide a railway control system and a railway control method for controlling railway vehicle information to be transmitted to a control center in real time or in non-real time depending on the type of railway vehicle, thereby eliminating problems caused by excessive transmission or omission due to excessive transmission To provide an information transmission device for a railway vehicle.

If the railway car information is train-provided air pressure information, train lane vibration information, and train ATC status information, the control unit transmits real time to the control center through the LET modem and stores the other vehicle information in a memory. The control unit transmits to the control center.

The Wi-Fi module becomes active when approaching within a range where wireless communication with the Wi-Fi module of the control center is performed.

The boards communicate with each other using a standard system bus implemented as a back plane PCB, The CPU board and the gateway board are connected to each other via a point-to-point Ethernet.

The CPU board operates the LET modem and transmits the LET modem to the control center in real time only when the railway car information is the train providing air pressure information, the train lane vibration information, and the train ATC status information. To the control center.

According to the present invention, railway vehicle information, which is distributed and monitored by fields and functions such as signals, vehicles, facilities, etc., is processed into one standardized protocol and transmitted to the control center. Therefore, the analysis and processing ability of the control center on the information of the railway car is improved, so that it has an effect of being able to respond appropriately in case of an accident and an accident.

Since the present invention transmits railway information to a control center through two methods of real-time transmission through an LTE modem and non-real-time transmission through a Wi-Fi module, it is possible to minimize a transmission failure probability due to over- The information can be transmitted stably. In addition, information on the safety of the railway car is prioritized and transmitted to the control center in real time, so that the risk of potential accident can be predicted, and it is expected that the management of the railway vehicle can be efficiently performed.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. The train control device (TSMD) of the present invention can be installed in a predetermined place in a passenger car by forming an overall appearance with a predetermined case, and at least one information control device (TSMD) is installed in a train of the train. As shown in FIGS. 1 and 2, the TSMD 100 includes four unit modules, that is, a CPU board 110, a gateway board 120, a power board 130, and a backplane board 140, and an LTE modem interface 150 and an expansion interface are installed on the rear surface.

The internal structure of such a TSMD device 100 is shown in Fig. As shown in the figure, the CPU board 110, the gateway board 120, and the power board 130 are configured to communicate using a standard system bus. The standard system bus is implemented as a back plane PCB, and is connected to the boards 110, 120, and 130 through connectors (not shown). In the present invention, the standard system bus is a Compact PCI serial device having PCI Express, SATA, USB, and Ethernet interfaces. In addition, communication between the CPU board 110 and the gateway board 120 through the standard system bus can be performed using a point-to-point Ethernet , 100base-T).

In particular, the CPU board 110 performs overall operation of the TSMD apparatus 100. In particular, the CPU board 110 transmits railway vehicle information, that is, TCN (Train Communication Network) data processed by the gateway board 120, As shown in FIG. At this time, the CPU board 110 controls data to be transmitted using different communication networks depending on the type of the TCN data. The communication network includes an LTE network (or a 3G network, hereinafter referred to as an LTE network) and a Wi- And the types of data to be transmitted are summarized in the following [Table 1] and [Table 2].

In the above Table 2, the RP (main air pressure) data is information related to the train-supplied air pressure information, and the braking instability data is information related to the train braking vibration information and includes traction / braking commands, The information related to opening, main circuit breaker input permission, traction / braking command, main circuit breaker failure information related to the ATC status information of the train is information to be transmitted in real time through the LTE network. And the rest of the information is information transmitted through the Wi-Fi network.

As another unit module configured in the TSMD device 100, the power board 130 serves to convert a power source for a train (DC 100 V) to a power source (DC 12 V) of the TSMD device 100.

The gateway board 120 configured in the TSMD device 100 captures the railway vehicle information of Table 2 that is provided through the control unit 121 and is provided through a multifunction vehicle bus (MVB) network, which is one type of TCN To the CPU board (110).

The gateway board 120 is provided with a capture unit 122 for capturing data as described above. The capture unit 122 is an MVB interface device. In the present invention, the MVB interface is connected to the controller 121 through a PCIe (PCI Express) bus. Unlike a conventional parallel bus (VME, PC104, PCI), the PCIe bus is advantageous in miniaturization because it has a small number of bus data connections and is advantageous in terms of EMI, low cost, fault tolerance, reliability and the like. And is suitable for the TSMD device 100 of the present invention which requires processing of all MVB data.

One or more WiFi modules 124 for using a Wi-Fi network are mounted on the gateway board 120 and various types of communication may be performed in various ways depending on the type of the LTE modem 10 for interfacing with the LTE modem 101. [ An interface 125 such as an Ethernet 125, a USB 126, and an RS-232C 127 are mounted so as to be able to communicate with each other. Here, the Wi-Fi module 124 may be directly mounted at a predetermined position of the case in addition to the gateway board 120.

The gateway board 120 includes a protocol conversion unit 123 for converting the railway car information captured by the capture unit 122 into a standardized TCN MVB protocol. The protocol conversion unit 123 of the present invention is advantageous in that integrated monitoring of all railway vehicle information can be performed in real time. In other words, conventionally, since different protocol standards are used for each terminal device that collects railway car information, integrated monitoring in real time is difficult.

The gateway board 120 is provided with a memory 128 in which data to be transmitted to the control center 200 through the Wi-Fi module 124 is temporarily stored. That is, since the WiFi module 124 mounted on the gateway board 120 is activated when it is within a predetermined distance from the control center 200, the railway car information is stored in the memory 128, and the railway car information is transmitted to the control center 200 when entering the vehicle base.

Next, a method of transmitting the information of the railroad cars collected in the train to the control center using the TSMD device having such a configuration will be described. First, when power is supplied for the operation of the railway vehicle (S100), various sensors and terminal devices installed in the railway car start to detect or check the railway car information of the railway car. The information on the railroad cars that are sensed or checked is transmitted to the MVB network (S102).

Then, the capture unit 122 of the TSMD device 100 installed in each carriage communicates with the MVB network to capture various railway vehicle information (S104). In other words, all the railway vehicles in the MVB network are input.

The CPU board 110 receives the protocol-converted railway car information and confirms the type of railway car information (S106). The types of the railway car information are as shown in Table 2, and it is confirmed whether or not the information of the [Table 1] is present among the railway car information. In other words, the information in [Table 1] refers to air pressure information related to train braking, vibration information of train bogies, and train ATC status information.

As information corresponding to the above railway car information, namely, RP (main air pressure) information, lane instability information, traction / braking command information, vehicle condition display indication information, main circuit breaker opening information, Information for traction / braking command information, and main circuit breaker failure information (S108). Such information is information that must be transmitted to the control center in real time.

However, since the sensor or the terminal device uses a different protocol standard, the capture information of the railway car captured by the capture unit 122 also has different protocols. And, if the railway car information is different format like this, it is necessary to convert it into one standardized protocol because it is difficult to perform quick analysis as described above.

Accordingly, the protocol conversion unit 123 receives the railway car information captured by the capture unit 122 and converts the railway car information into the TCN MVB protocol (S110). The message structure according to the protocol conversion process is as shown in [Table 3], [Table 4], [Table 5], and [Table 5].

[Table 3] TSMD protocol message structure (1)

[Table 4] TSMD protocol message structure (2) - On-board device time

[Table 5] TSMD protocol message structure (3) - TSMD device time

[Table 6] TSMD protocol message structure (4)

When the conversion of the protocol is completed, the CPU board 110 transmits the railway vehicle information to the control center 200 through the LTE modem 101 in real time (S112).

On the other hand, when information other than the railway car information is transmitted, the CPU board 110 stores the information in the memory 128 (S114). The stored railway vehicle information is converted into a standardized protocol through the protocol conversion process of the protocol conversion unit 123 described above, and is continuously stored until the WiFi module 124 is activated. That is, the railway vehicle information remains in the stored state until the railway vehicle enters the vehicle base and the Wi-Fi module 124 and the Wi-Fi modules of the control center 200 in the vehicle base can communicate with each other .

When the WiFi module 124 and the WiFi module of the control center 200 can communicate with each other, the CPU board 110 transmits the railway car information to the control center 200 through the WiFi module 124. [ (S116). At this time, the vehicle information transmitted to the control center 200 may be transmitted in the order stored in the memory 128, or may be transmitted according to the priority specified by the user. The priority may be information requiring priority confirmation in relation to the safety of the railway vehicle.

In this case, the control center 200 can receive the railway vehicle information converted into one standardized protocol and thus can perform a quick process, and real-time transmission through the LTE network or non-real-time transmission through the Wi- The vehicle information can be selectively transmitted according to the priority order, so that it is possible to provide the potential accident risk prediction information through immediate alarm or big data analysis for accident prevention. As a result, it is possible to effectively eliminate the immediate danger, thereby minimizing the possibility of an accident.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.

That is, in the embodiment of the present invention, the CUP board 110 transmits the railroad car information to the control center 200, but the controller 121 of the gateway board 120 may be configured to perform such a role It is possible. That is, the function of the CPU board 110 is added to the control unit 121, so that the number of boards to be installed can be reduced, and the size of the TSMD apparatus 100 can be further reduced.

In addition, the process of converting the railway car information into one standardized protocol may be performed immediately after confirming the vehicle information before determining the real time transmission object information.
