[0002]

2. Description of the Related Art Generally, in the case of a train, the train electrically short-circuits the two rails on the left and right sides. Therefore, by measuring the resistance value in one closed section between traffic lights,
It is possible to detect whether or not a train has entered a certain closed section. That is, the position of the train can be automatically detected for each closed section. When a train enters a certain closed section, the traffic signal and the switch are automatically switched so that the subsequent train does not enter, and the operation is controlled so as to automatically prevent the collision of the train. Have been.

However, when a maintenance vehicle is used for replacing rails and sleepers of a railway line, tamping a ballast, checking an overhead line, and replacing a railroad, a maintenance vehicle is used so that the two right and left rails are not short-circuited.

[0004] Therefore, since the position of the maintenance vehicle by such an insulated traveling cannot be automatically detected, usually, a supervisor who uses the maintenance vehicle and the operation of the maintenance vehicle based on the work order are required. The position of the maintenance person was confirmed by verbal communication using a dedicated line with a commander or a station signal operator, and a predetermined operator performed switching of the traffic lights and turnouts to manage the operation.

[0005]

Therefore, in the case of a maintenance vehicle by such an insulated running, it depends only on the verbal transmission of a person, and a traffic signal or a branch is made so as to close a line in one closed section. Although it is necessary to switch the equipment, there is a possibility that the switching may be neglected due to human error such as forgetting. If you forget to switch between traffic lights and switches,
This permits a subsequent train to enter the section where the maintenance vehicle is present, and causes a collision accident between the train and the maintenance vehicle. This is a problem that must be avoided. In particular, work with a maintenance car is often performed at night when trains are running at intervals, under conditions that easily cause fatigue, human error easily occurs, and it is difficult to confirm the situation at the work site. , It was shouted to take some measures.

In this embodiment, for example, FIG.
As shown in the figure, the sleeper 6 is located at the start and end points of one blockage section.
The recognition plates 7a to 7h installed above are attached. As shown in FIG. 4A, the identification plates 7a to 7h are formed by encapsulating an ID tag (transponder) 9 in which arbitrary information can be written and read at any time by an electromagnetically modulated wave with a resin 10, and It is not affected by weather conditions such as snow and snow. Recognition plate 7a
Are arranged as a set of two before and after the start point and end point of one closed section. This is for detecting the traveling direction of the maintenance vehicle 1.

Each of the recognition plates 7a is shown in FIG.
As shown in (1), it has a transmitting / receiving unit, a control unit, and a data holding unit (IC chip), and receives energy for operation and gives energy for operation and response by receiving an electromagnetically modulated wave. The energy is stored in the capacitor, and the information written in the data holding unit is transmitted by the charge stored after the reception is completed.

Thus, the position detecting device 2 of the maintenance vehicle 1
As shown in FIG. 1, an antenna 11 for writing and reading information to and from the ID tag 9 of the recognition plate 7a, a reader 12 for analyzing and displaying the read information, , And a wireless communication device 13 for transmitting the data as shown in FIG. 3 (A). That is, the reader 12 includes a transmission / reception unit that performs transmission and reception via the antenna 11, a control unit, a display unit, and an operation unit. The wireless communication device 13 exchanges information with the control unit of the reader 12 and can transmit the information via the antenna 14.

On the other hand, as shown in FIG. 1, a signal from the wireless communication device 13 is received at the starting point of a certain closed section.
A display device 4 for displaying this is provided. The display device 4 includes an antenna 15 and a wireless communication device 16,
The display control unit 17 and the special traffic light 3 are configured as shown in FIG. 3B. That is, the display control unit 17 includes a control unit that exchanges information with the wireless communication device 16, an operation unit, and a display unit. The special traffic light 3 includes a control unit for exchanging information with the control unit of the display control unit 17, a driving unit, and a light emitting unit. As shown in FIG. 1, the light emitting unit includes LEDs 18 arranged vertically and horizontally.

Writing of information to the ID tags 9 of the recognition plates 7a... Is performed in advance by the information setting machine 8 shown in FIGS. 5A and 5B. This information setting machine 8
Has an operation section 19 for inputting data and a display section 20 for displaying the operation section, as shown in FIG. Then, as shown in FIG. 7B, the information input from the operation unit 19 is sent to the transmission / reception unit via the control unit, and is input to the recognition plates 7a to 7h via the antenna 21.
The data is written to the data holding unit. The information to be written, for example, shows the names of line sections such as the Tokaido line, Kisei line, Hanwa line, and circular line, the names of each closed section, the line of the up line or the down line, and the distance from the starting point of each line section. About a kilo.

Next, the operation of the maintenance vehicle position detecting device 2 configured as described above will be described with reference to FIG. The operation management of the train including the maintenance car 1 is performed comprehensively in the command center of the station in the station station and the station station of the B station. Will be Therefore, there is no problem that a collision accident between the maintenance car 1 and another train occurs.

Now, it is assumed that the operation using the maintenance vehicle 1 is performed in a closed section between the stations A and B. The maintenance vehicle 1 departs from the base 22 in the station A, enters the main line from the pull-up line, and approaches the recognition plate 7a installed at the end point in the station A. In the reader 2 of the maintenance vehicle 1, the control unit instructs the transmission / reception unit to intermittently transmit the electromagnetically modulated wave only for a short time of, for example, only 30 mS. Therefore, an electromagnetically modulated wave is supplied to the recognition plate 7a from the transmission / reception unit via the antenna 11, and the transmission / reception unit of the recognition plate 7a receives energy for operation and response by the electromagnetically modulated wave, and stores the electric charge. And
When the supply of the electromagnetically modulated wave from the reader 12 is stopped, the recognition plate 7a reads the name of the line section such as the Tokaido line, the name of the closed section, the up line, which is written in the data holding unit by the electric charge accumulated in the capacitor inside the recognition plate 7a. Or, send information such as down line and kilometers.

The information transmitted from the recognition plate 7a in this manner is received by the transmission / reception unit of the reader 12 through the antenna 11 of the maintenance vehicle 1, and is input to the control unit. The control unit of the reader 12 determines the course direction and the current position of the maintenance vehicle 1 from the information written on each recognition plate received as the maintenance vehicle 1 further advances as described above. . For example, when the information from the recognition plate 7a is read first, and then the information from the recognition plate 7b is read immediately, it is proceeding on the down line from the station A to the station B, and is currently blocked in the station A. It is detected that the user is at the end point of the section. When the maintenance vehicle 1 further moves forward, the information on the recognition plates 7c and 7d is sequentially read, and the maintenance vehicle 1 reaches the starting point of the closed section between the stations,
It can be detected that the vehicle has entered the closed section.

In the closed section between the stations, the current position of the maintenance car 1 cannot be confirmed at the command center at the station A, so the control unit of the reader 12 transmits the current position from the antenna 14 through the radio communication device 13. The current position of the maintenance vehicle 1 is transmitted.
This transmission signal is received by the wireless communication device 16 through the antenna 15 of the display device 3 installed near the end point in the station A, for example, and is input to the display control unit 17. Display control unit 1
7 transmits this to the control unit of the special traffic light 3 and causes the light-emitting unit composed of the LED 18 to display a light-emitting signal through the drive unit. Even if the following train approaches, the driver is prohibited from entering the closed section between the stations by the light emission signal of the LED 18, so the driver stops before the section, Collision with the maintenance vehicle 1 can be avoided. That is, the closed section between the stations where the maintenance vehicle 1 is currently located is securely closed.

Information such as the course direction and the current position of the maintenance vehicle 1 transmitted from the antenna 14 of the wireless communication device 13 is simultaneously transmitted to a command center at a station or a command center for centralized control of trains. It is possible to safely and reliably perform comprehensive operation management of the train including the maintenance vehicle 1 through all the track sections. When a plurality of maintenance vehicles 1 perform predetermined track work or the like, the maintenance vehicle 1 can detect each time the recognition vehicle 7 passes through each recognition plate 7a. It is also possible to grasp the exact number of vehicles.

After completion of predetermined track work by the maintenance vehicle 1 in the closed section between the stations, the recognition plates 7e to 7e
h, it is possible to detect that the maintenance car 1 has escaped from the blockage section and has reached the station B station, and displays the course direction and the current position of the maintenance car 1 in the same manner as described above. It can be input to the display control unit of the device 4. As a result, the light emission display of the special traffic signal 3 is canceled, and if there is a subsequent train, the subsequent train can enter the closed section where the station is empty. In the case where work is performed using a plurality of maintenance vehicles 1, the number of the maintenance vehicles 1 is also grasped. Therefore, after the last maintenance vehicle 1 escapes from the closed section, the light emission display of the special traffic light 3 is released. Will be done. The maintenance vehicle 1 that has arrived at the station B may enter the base from the pull-up line and wait.

Incidentally, the present invention is not limited to the above-described embodiment, and can be appropriately changed. For example, the wireless communication devices 13 and 16 can use mobile phones, and can also use radio waves in other frequency bands. If you use a mobile phone,
It is possible to transmit information to almost the whole area of the whole country, and it is convenient when the train control center is a long distance.
Each recognition plate 7a is used by the position detecting device 2 of the maintenance vehicle 1.
, And after detecting the course direction and the current position of the maintenance vehicle 1, the information is converted into a signal and the maintenance vehicle 1 is signaled.
By transmitting a signal to the display device 4 using a mobile phone or the like, the operator can cause the LED 18 of the special traffic light 3 to emit light. Further, as the ID tag 9,
Various commercially available products such as a glass-sealed type, a wedge type, a large type, a disk type, and a plate type can be used.

As described above, according to the present invention, a recognition plate is installed at the start point and the end point of the work section in the railway track, and the information written on the recognition plate is not read by the maintenance vehicle. Since the direction and current position of the maintenance vehicle that reads in contact and performs insulated running on the track are reliably detected, comprehensive operation management of the train, including the maintenance vehicle, is used based on this information. It is extremely safe, and the work efficiency can be improved.

Further, by transferring information such as the course direction and the current position detected by the maintenance vehicle to another remote place by a wireless communication system, the following train does not enter the closed section where the maintenance vehicle is located. As described above, a signal can be displayed on the near side, and safety can be established.

Further, the writing to the recognition plate and the reading of the written information can be performed by a wireless method, and it is difficult to confirm the visual information visually, at night, in bad weather such as wind and rain or snow, or when the recognition plate becomes dirty. Even if there is any influence, the information can be reliably exchanged within the communicable area, and the reliability is extremely high.
