Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for managing train operation data,

The present invention relates to a train operation data management method for managing data generated during a train operation and an apparatus therefor.

Today, there are campaigns to encourage the use of trains to solve environmental problems or traffic problems, and train routes are also increasing. A system for managing trains has been developed to identify the intervals between these trains and to ensure the safety of trains. The following patent document discloses a train operation management system.

Data generated during train operation is collected continuously and stored in the storage space in the train. When the train is stopped, the collected data is extracted by the manager and used for maintenance of the train.

However, among the data generated during the train operation, data indicating a fatal failure may exist or general train operation data may exist.

Among these various types of train operation data, data indicating fatal obstacles should be immediately reported to the control center. Conventionally, even if a fatal obstacle occurs in a train, it is reported to the control center only by manual operation of the operator. That is, in the past, the engineer manually confirms data indicating a fatal obstacle through a control device installed in the train, and reports it to the control center through a communication means such as a walkie-talkie.

Such a manual reporting method is a method in which a train obstacle is handled in dependence on the ability of an engineer, and when an engineer having poor ability to operate operates the train, proper reporting and response are delayed or not progressed.

In the class (33), the grade of the train operation data is recorded. The class (33) represents the main class of the train operation data. The class (1) can have a great influence on the train operation and should be processed immediately to indicate the data class. The class (2) And grade 3 is the rating for data indicating a low level of disability that does not affect train operation. In addition, grade 4 is a rating that represents general data that does not cause problems with train operation. That is, among the data classes, the first class represents the most important class of data, and the first through fourth classes have lower data importance.

The data collecting unit 240 collects the components installed in the train, such as a fire detector, a battery charging system, a Central Control Unit (CCU), a traction motor controller (TMC), a braking device, And receives the train operation data generated by the corresponding device. At this time, the data collecting unit 240 receives train operation data including data codes from each device. The data collecting unit 240 may connect a cable such as an RS-242 to a component installed in the train.

When the data collection unit 240 collects the train operation data, the class determination unit 250 identifies the data code included in the train operation data and transmits the data class corresponding to the data code to the data class of the storage unit 230 And confirms the classification of the collected train operation data.

The stop detection unit 260 performs a function of monitoring whether the train is in the stop state. The stop detection unit 260 may communicate with components in the train such as a braking device and a speed measuring device to detect whether the train is stopped.

The data processing unit 270 transmits the train operation data to the control center 300 via the remote wireless communication unit 220 on the basis of the degree of the collected train operation data or stores the data in the storage unit 230 . Specifically, when the train operation data collected by the data collecting unit 240 is determined to be one grade, the data processing unit 270 immediately transmits the train operation data to the control center 300 through the remote wireless communication unit 220 .

On the other hand, if the train driving data collected by the data collecting unit 240 is not in the first grade, the data processing unit 270 stores the train driving data in the storage unit 230, And transmits the operation data to the control center 300 through the short-range wireless communication unit 210. If the access point 111 is detected in the vicinity of the train while the stop detection unit 260 senses the train stop, the data processing unit 270 determines whether the access point 111 is within an access point The access point installed in the history selects a certain number of train operation data having the highest rank except for the first rank and then transmits the selected number of train operation data to the short range wireless communication unit 210, To the control center (300). If the access point 111 sensed in the vicinity of the train is an access point installed in the vehicle base, the data processing unit 270 transmits all the train operation data stored in the storage unit 230 (i.e., the train operation data To the control center 300 by using the short-range wireless communication unit 210.

When the second class train operation data having different data codes and having the same type are repeatedly collected, the data processing unit 270 uses the long-range wireless communication unit 220 to operate the second- Data can be immediately transmitted to the control center 300.

4 is a flowchart illustrating a method of collecting train operation data in a data management apparatus and selectively transmitting the data to a control center according to an embodiment of the present invention.

Referring to FIG. 4, the class determining unit 250 monitors whether the data collecting unit 240 collects train operation data from a plurality of components mounted in the train (S401).

Then, when the data collecting unit 240 collects the train operation data, the class determining unit 250 checks the data code including the train operation data, and stores the data grade mapped to the data code in the storage unit 230 (Step S403).

When the class determining unit 250 confirms the data rating, the data processing unit 270 determines whether the determined data rating is rank 1 (S405).

If the determined data grade is the first rank, the data processor 270 accesses the base station 121 of the mobile communication network 120 using the long-range wireless communication unit 220, The collected first-class train operation data is transmitted (S407). That is, the data processing unit 270 transmits the train operation data determined as the first rank to the control center 300 via the mobile communication network 120. Then, the control center 300 receives the train operation data corresponding to the first rank and outputs it to the screen, thereby confirming occurrence of a major disturbance on the train, adjusting the intervals of the train, dispatching maintenance personnel can do.

On the other hand, if the collected train operation data is not 1 grade, the data processor 270 checks whether the train operation data is grade 2 (S409).

If the collected train operation data is classified as the second class, the data processing unit 270 determines whether or not the second class train operation data having the same data code as the train operation data is stored in advance in the storage unit 230 (S411). That is, if the train operation data is class 2, the data processor 270 determines whether the train operation data of the same type and the same data class as the train operation data is collected repeatedly, Based on the running data of the vehicle. Also, the data processor 270 can identify the type of the train operation data by checking the type corresponding to the data code included in the collected train operation data in the data rating table of the storage unit 230.

The data processor 270 has a data code different from that of the second-class train, and if the second-class train data having the same type is already stored in the storage unit 230, the data processor 270 uses the long- And transmits the collected train operation data and second class train operation data corresponding to the same type stored in the storage unit 230 to the control center 300 in step S407. That is, when the second-class train operation data of the same type is repeatedly collected, the data processing unit 270 determines that there is a high probability of occurrence of a major obstacle in the train, so that the second- And reports it to the control center 300 via the communication network 120. Then, the control center 300 receives the train data of the same type corresponding to the second grade and outputs the same to the screen, thereby analyzing the trouble occurring in the train and determining the cause. Also, Train personnel can dispatch maintenance personnel.

On the other hand, if it is determined in step S409 that the train operation data is not the second grade but three or less (i.e., third or fourth grade), the data processing unit 270 stores the collected train operation data in the storage unit 230 ). In step S411, if the second-class train operation data corresponding to the same type is not already stored in the storage unit 230, the data processor 270 transmits the collected second-class train operation data to the storage unit 230 .

5 is a flowchart illustrating a method of transmitting train operation data to a control center using a short-range wireless communication network in a data management apparatus according to an embodiment of the present invention.

Referring to FIG. 5, the stop detection unit 260 monitors whether or not a train is detected by communicating with the components of the train, and detects the stop of the train (S501). At this time, the stop detection unit 260 may communicate with the braking device, the speed measuring device, and the like installed in the train to detect whether the train stop is proceeding.

When the stop detection unit 260 detects the train stop, the data processing unit 270 searches the neighboring access point 111 through the short distance wireless communication unit 210 (S503). That is, the data processing unit 270 searches whether the access point 111 is detected in the vicinity of the station where the train is stopped, using the short-range wireless communication unit 210. [

When the access point 111 is found in the vicinity, the data processing unit 270 determines whether or not the access point 111 is accessible (S505). At this time, the data processing unit 270 acquires the identification information of the access point 111 detected in the vicinity through the short-distance wireless communication unit 210, and determines whether the obtained identification information is registered in the AP list of the storage unit 230 It is possible to determine whether or not the searched access point 111 is reachable.

Next, if the searched access point 111 is an access point to which the searched access point is connectable, the data processing unit 270 determines whether the access point is an access point installed in a vehicle garage or in a history (S507). That is, the data processing unit 270 checks whether the identification information of the installed access point of the car garage stored in the storage unit 230 matches the identification information of the nearby access point, Whether it is an access point installed in a garage or in a history.

The data processing unit 270 accesses the access point 111 using the short range wireless communication unit 210 when the access point 111 is detected as an access point 111 installed in the history. Then, the data processing unit 270 selects a certain number of train operation data corresponding to the highest rank among the train operation data of the storage unit 230 that has not been transmitted to the control center 300 (S509). At this time, the data processing unit 270 can dynamically set the number of selected train operation data based on the radio signal sensitivity intensity and the stop time with the access point 111. [ In addition, the data processing unit 270 may set the number of driving data to be pre-populated, and may select the train operation data corresponding to the set number in the storage unit 230.

Next, the data processing unit 270 transmits the selected number of train operation data to the control center 300 using the local area wireless communication network (i.e., access point) (S511). In addition, when the train stops in history, the data processing unit 270 accesses the access point 111 installed in the history, and then transmits a predetermined number of train train operation data with a high rating to the control center 300 preferentially . That is, the data processing unit 270 accesses the neighboring access point 110 using the time that the train stops in the history, extracts a plurality of train operation data corresponding to a high grade from the storage unit 230, (300).

If it is detected in step S507 that the access point 111 is installed in the vehicle base, the data processing unit 270 transmits the access point 111 installed on the base of the vehicle using the short- ). The data processing unit 270 extracts all the train operation data that have not been transmitted to the control center 300 from the storage unit 230 and transmits all of the extracted untransmitted train data through the access point 111 installed in the vehicle base And transmits the operation data to the control center 300 (S513).

As described above, the present invention confirms the class of the train operation data collected in the train, reports the train operation data corresponding to the main class to the control center 300 through the mobile communication network 121, And to take action accordingly. In addition, the present invention reports train operation data that does not correspond to a major class to the control center through the short-range wireless communication network 110, thereby reducing wireless communication charges incurred in using the mobile communication network. In addition, when a train stops in the history, the present invention first selects train operation data corresponding to a higher grade and reports to the control center 300 through the short-range wireless communication network 110 in priority.
