Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to position information from an ID tag installed on a track so that a maintenance vehicle used for construction and maintenance inspection work of railway tracks and overhead lines does not deviate from the approval section, and approval section information from a notice And an approval section deviation prevention device for a maintenance vehicle that monitors so as not to deviate from the approval section.
[0002]
[Prior art]
Normally, in the case of a train, since the train electrically short-circuits the two rails on the left and right, the train enters a certain blockage section by measuring the resistance value in the blockage section between the traffic lights. It is possible to detect whether or not. That is, it is possible to automatically detect the position of the train for each closed section. And when a train enters a certain closed section, the traffic lights and turnouts are automatically switched so that the following train does not enter, and the operation is carried out so as to automatically prevent a train collision accident. It is managed.
[0003]
However, when using maintenance vehicles such as railroad rail and sleeper replacement, ballast tamping work, overhead wire inspection and reworking work, the right and left rails are insulated from the maintenance car so that they are not short-circuited. It is impossible to automatically detect the position of the maintenance vehicle. This is often the case when a plurality of maintenance vehicles enter the same closed section at the same time and perform the desired work, or when the maintenance car stops for a long time at a position close to the level crossing and performs a predetermined work. This is because the railroad crossing breaker remains down, resulting in traffic obstruction on the general road that crosses the railroad crossing. Furthermore, due to the relationship between the base and the place where the work is performed, the maintenance vehicle may travel on the track in the direction opposite to the traveling direction of the train (reverse travel). This is because it may cause damage.
[0004]
To prevent such accidents when using maintenance vehicles, the maintenance vehicle operator checks the position of the maintenance vehicle while switching between short-circuit traveling and insulated traveling, and commands, station staff, etc., the maintenance vehicle and the maintenance vehicle supervisor. Signals and branching devices are switched by communication between both persons such as persons. In other words, it relied solely on human attention and could lead to accidents due to human error.
[0005]
Therefore, in the prior art, as described in Patent Document 1, ID tags are installed at the start and end points of the short-circuit traveling section and the insulating traveling section in the railroad track, and written on this on the maintenance vehicle side. Information is read in a non-contact manner to acquire position information, and automatic switching between short-circuit traveling and insulated traveling is performed.
[0006]
Also, in the technique described in Patent Document 2, as in Patent Document 1, ID tags are installed at the start and end points of one closed section in the railway track, and written on this on the maintenance vehicle side. The information is read in a non-contact manner to acquire position information, and the traffic light is switched based on this information to prevent the following train from entering.

[Problems to be solved by the invention]
However, in the techniques described in Patent Documents 1 and 2, the position information of the maintenance vehicle is simply read from the ID tag installed in the railway track on the maintenance vehicle side in a non-contact manner, and the insulation travel and the short circuit are performed. Switching of driving, switching of traffic lights, etc. were performed automatically. For this reason, it is not possible to automatically determine whether the maintenance vehicle is traveling within the approved section or not deviating from the approved section according to the route information. In the work, there was a risk that human error would occur due to the need to rely only on the attention of both the command and station staff and the maintenance car supervisor.
[0009]
The present invention is an improvement and removal in view of the above-mentioned problems in the past, by comparing the approval section information acquired from the route information of the notification and the position information read from the ID tag on the orbit, Even in a complicated and complicated station premises, the vehicle can travel to a target location without departing from the approval section, and the safety of the maintenance vehicle and the station premises is ensured.
[0010]
[Means for Solving the Problems]
The means of claim 1 employed by the present invention includes: a notification form issuing device that extracts and issues route information from line-specific information of a notification; and an approval interval input device that acquires approval interval information from the issued route information. The position information reading device that reads the position information from the ID tag installed on the track, the approval section information from the approval section input device and the position information from the position information reading device are collated, and deviates from the approval section. And an apparatus for preventing departure from an approved section of a maintenance vehicle, characterized in that it is configured with a processing device that issues a warning and a braking instruction when the vehicle is present.
In this invention, while obtaining the approval section information from the route information issued by the notice issuing device, the position information is obtained from the ID tag installed on the track, and the maintenance is performed by collating both pieces of information. It is determined whether the car is traveling according to the notice, and if it deviates from the approval zone, a warning or brake operation is performed.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The configuration of the present invention will be described below based on the embodiment of the invention shown in the drawings. FIGS. 1 to 3 relate to an embodiment of the present invention. FIG. 1 is a block diagram showing the overall configuration of an approval section departure prevention apparatus for a maintenance vehicle, and FIG. 2 shows the procedure of the approval section departure prevention method. Drawing for explaining, FIG. 3 is a track plan view of a station premises showing an example of arrangement of ID tags. As shown in FIG. 1, the maintenance section approval section deviation prevention apparatus according to the present embodiment includes a notification form issuing apparatus 1 installed in a track maintenance office, an ID tag 2 installed on a track, maintenance The position information reading device 4, the approval section input device 5, the processing device 6, and the alarm device 7 are installed in the car 3.
[0012]
The notice issuing device 1 has a personal computer 8 installed in the track maintenance office. The personal computer 8 creates a notification form 9 based on a track maintenance work instruction transmitted from a host track maintenance management computer (not shown) or the like and issues it. The notification form 9 includes selection information, specific instructions for track maintenance, route information to the destination, and the like. Further, the personal computer 8 extracts route information from the notice 9 and writes it into a storage medium 10 such as an IC card.
[0013]
On the other hand, the ID tag 2 installed on the track is installed on the sleeper, and the name of each line section such as the Tokaido Line, Kisei Line, Hanwa Line, Loop Line, etc., each blocked section name, and the up line or down line The location information is recorded for each line, such as the electric train line and the covering line, and about a kilometer from the starting point of each line section. The ID tag 2 is provided with energy for operation and response by receiving electromagnetic modulation waves. This energy is accumulated in the capacitor, and information written in the data holding unit is transmitted by the accumulated electric charge after reception is completed.
[0014]
Further, the reading device 4 of the maintenance vehicle 3 receives the output signal of the ID tag 2 and outputs it to the processing device 6. Further, in the approval section input device 5, the operator of the maintenance vehicle reads the information from the IC card 10 by, for example, a card reader or the like, and displays the route information of the notification form on the screen. Route information is recorded for each track, such as in a station premises that reaches a destination beyond a plurality of tracks. Therefore, the operator manually inputs the approved section for each track to the processing device 6 as needed. This is for the operator to confirm each time it passes through each track, but it is also possible to automatically input it.
[0015]
The processing device 6 inputs the approval section information from the approval section input device and the position information transmitted from the ID tag 2 through the reading device 4 and compares both information to determine whether the current maintenance vehicle 3 is present. It is judged whether the vehicle is traveling within the approval zone or has not deviated from the approval zone. If the vehicle has deviated from the approval zone, an alarm signal is output to the alarm device 7 to call attention, and the brake device A forced brake braking is performed by outputting a signal to.
[0016]
FIG. 3 shows an arrangement example of the ID tag 2 in the Tsukaguchi station. By sequentially acquiring the position information of each ID tag 2 and collating it with the approval section information input from the IC card 10, it is possible to determine where the maintenance vehicle 3 is currently from, where it is, and where it is going. Is possible. And when it has deviated from the recognition section, as mentioned above, processing device 6 performs a warning and a brake output.
[0017]
For example, the maintenance vehicle 3 is now on the 0th line (indicated as 0 # in FIG. 3) of the maintenance line, and from here to the station on the down line (between 1k782 to 2k791) Assume that track maintenance work is performed. First, the route information extracted from the notification form 9 issued by the personal computer 8 in the track maintenance office is written in the IC card 10. Then, this is read into the approval section input device 5 of the maintenance vehicle 3 by a card reader or the like and automatically input to display on the screen.
[0018]
Next, the operator of the maintenance vehicle 3 operates the maintenance vehicle 3 while viewing the displayed route information for each track. The maintenance vehicle 3 that departs from the maintenance line No. 0 reads the position information from the 11th ID tag installed at a position of about 1 k782 by the reader 4 and enters the P line. Prior to entering the P line, the processing device 6 collates the position information from the 11th ID tag with the approval section information read from the IC card 10.
[0019]
If it does not deviate from the approval section, the operator performs a screen operation such as clicking an icon displayed on the screen so as to shift to the next approval section information determination screen. As described above, this operation is intentionally set by the operator to confirm the safety, and can be automatically performed. When the vehicle deviates from the approval section, the alarm device 7 may be instructed to issue an alarm, and a brake braking signal may be output to the brake control device to forcibly stop.
[0020]
Next, the maintenance vehicle 3 reads the position information from the 15th ID tag installed at a position of about 1 km 960 on the P line, and enters the communication line with the up line. Then, the information from the ID tag is compared with the approval section information input from the IC card, and it is determined whether or not the approval section has been deviated in the same manner as described above. If not deviating, the operator operates the screen so as to shift to the next approval section information determination screen. If it deviates, it will be an alarm and brake output.
[0021]
Thereafter, the vehicle enters the up line in the same manner, and further enters the connecting line between the up line and the down line from this up line, and travels to the maintenance work section of the down line. The up line and the down line are tracks on which the business train travels, and by inputting information from the central train control device (CTC), it may be performed using a time zone that does not hinder the operation of the business train. .
It should be noted that if the position information of the first ID tag installed at the position of 1k782 and the fourth ID tag installed at the position of 2k791 is detected in the maintenance work section of the down line, an approval is given. It is going to deviate from the section, and it becomes an alarm and brake output.
[0022]
After the predetermined maintenance work is completed, the return operation is performed up to the material holding line 0 #. The return route may be the reverse route in the case of the outward route according to the instruction of the route information written in the IC card 10, or may be another route.
[0023]
By the way, the present invention is not limited to the above-described embodiment. For example, the arrangement example of the ID tag can be appropriately changed according to the track configuration in the station, and the route information is written as it is. In addition to the IC card, other storage media can be used as the storage medium, and information exchange by a wireless communication method using a mobile phone may be used.
[0024]
【The invention's effect】
As described above, in the present invention, a notification issuance device that extracts and issues route information from line-by-line information of a notification, and an approval interval input device that acquires approval interval information from the issued route information; The position information reading device that reads the position information from the ID tag installed on the track, the approval section information from the approval section input device and the position information from the position information reading device are collated, and deviates from the approval section. If the maintenance vehicle approval section deviation prevention device is configured with the processing device that gives an alarm and braking instruction when the vehicle is in operation, it is determined whether the maintenance vehicle is traveling according to the notice, and deviates from the approval section. If it is, a warning or brake operation can be performed. Therefore, this determination does not involve humans and there is no possibility of human error.
