Abstract

PURPOSE:To improve the safety maintenance by mere designation and inputting of a travel track circuit which cause a searching of a track circuit link table to confirm the course connection appropriateness and cause a searching of a track circuit reservation table to confirm the competitivity, thereby outputting an alteration instruction to a corresponding railway point. CONSTITUTION:This interlocking apparatus is composed of a terminal 1 such as a computer, a wireless device, etc., a maintenance-car, etc., course preparation means 2 for preparing a given course for maintenance car, an emergency running train, etc., a travel track circuit reservation table 3, a travel track circuit link table 4, and a point control means 5. Whether or not the travel track circuit associated with an input course setting request is continuous is judged by searching for data in the travel track circuit link table 4. When that circuit is continuous, search is made for the travel track circuit link table 4 to confirm whether or not a reservation for, for example, another train is made for the travel track circuit. When no reserve is made in regard to any travel track circuit, an alternation instruction for a point and availability information are outputted.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to operation management of trains and vehicles (hereinafter collectively referred to as trains), management of train shunting work, maintenance vehicles and maintenance work-related,
Or, it relates to a railway management system that manages emergency operation, etc. in an emergency, and specifically, it refers to a railway management system that manages emergency operation, etc. The present invention relates to an interlocking device that automatically switches traffic lights to open a desired route and displays the opening of the route on a traffic light.

[Conventional technology] In places where railroad tracks converge and diverge in a complex manner, such as inside a railway station, there are switches, signals, signs, etc. that are used to open the route and indicate whether or not it is possible to enter the route. A large number of devices (hereinafter collectively referred to as route control devices) are installed to display the following information, and these devices are switched according to the arrival, departure, passing, etc. of trains and maintenance vehicles (hereinafter collectively referred to as trains, etc.). ,
Opening of routes requested by trains, etc. is being carried out.

The switching operations of these route control devices must be carried out promptly and appropriately in response to the arrival, departure, passage, etc. of trains, etc., so that the trains, etc. can operate and pass efficiently. Furthermore, there must be no mistakes in the operation of these route control devices, and if we relied solely on the operator's attentiveness to prevent such misoperation, as trains departed and arrived more frequently,
On the one hand, there is a risk of erroneous operation, and on the other hand, work efficiency is not improved.

Therefore, if a route control device is operated incorrectly, in order to eliminate the erroneous operation, ensure safety, and improve work efficiency, interlocks (chains) are established in advance for the operation relationships of multiple related route control devices. An interlocking device is used to set the lock (lock) and perform control operations accordingly.

In other words, the interlocking device first inputs data such as the departure point and destination of the train in accordance with the route setting request by the operator.
In response to this, the train checks whether the related route has already been set and opened by another train, and after confirming that it has not been set, the switch machine necessary to open the requested route is checked. It is designed to output a command to change the direction in a predetermined direction. Next, it is confirmed that the predetermined route has been opened based on the switching position signal output from the switch machine, and this is displayed on the display panel of the interlock device control panel. After setting a course in this way, it is necessary to disable the operation or work of other trains, etc. that block the course, and to secure the course until the train, etc. passes, by using related switch machines, etc. Outputs a lock command to. Next, the track circuit detection means confirms that there are no other trains or vehicles on the route, and the display of the relevant signal is switched to the [Progress (blue) J side] and locked, and the above display is Display on the board. After the train, etc. has passed through a predetermined point on the set route, the locks of the switch, etc. are released.

In this way, the operator can simply input data such as the departure and arrival points of trains, etc., and the route will be automatically opened without conflict, and the necessary displays will be displayed, which will not only prevent erroneous operations, etc. Frequent arrivals and departures of trains, etc. can be handled efficiently.

Conventionally, as interlocking devices having such functions, there have been known relay-type interlocking devices whose interlocking control logic is constituted by a relay circuit, and electronic interlocking devices using a microcomputer. The relay type interlocking device of the bender considers all possible combinations of switches, traffic lights, and each other in the controlled range and locks them, thereby covering dangerous erroneous operations and preventing malfunctions. The basic idea is to prevent In addition, route setting is performed using a departure lever/endpoint push button or a signal lever, and route conflicts with trains, etc. during the opening operation are eliminated by a route selection circuit or lever relay circuit assembled with a relay circuit, and related switching It is said to be an indirect competitive judgment method, such as locking a machine or eliminating it via a switch machine using a route locking mechanism.

[Problems to be Solved by the Invention] However, in conventional interlocking devices, relay circuits and spur files are created based on interlocking control data called an interlocking chart, and any arbitrary data not specified in the interlocking chart is created. It is difficult to construct a course for the future. In other words, a course is defined in the interlocking chart using the venue/departure signal, guidance signal, shunting signal, or shunting sign as an indicator, and interlocking control such as interlocking of course control equipment is performed in accordance with the specified course. Conditions are specified in an interlocking chart, and trains, etc. are operated based on the course and interlocking control conditions specified in this interlocking chart, which makes it difficult to construct an arbitrary course.

Therefore, in the case of an emergency operation in which a relief train or the like is operated in the opposite direction of the normal main line to tow a broken vehicle to a depot, etc., such a route and departure signal, etc. are not specified in the interlocking chart. The operator must manually turn the switch using a hand-cranked handle, lock the switch, and use a flag signal to show the crew a proceeding signal.

Such manual switching and locking of switch machines requires skill, and there is a problem in that regular training and sufficient experience are required to handle abnormal situations in a short time. .

In addition, the above-mentioned problems can also occur during emergency operations, such as when a train, etc. cannot stop at a designated location and overruns a traffic signal, causing the train, etc. to retreat or to continue moving forward. The same is true.

Also, when driving a maintenance vehicle, if the route is not set in advance, the only way to drive the maintenance vehicle is to use the point machine alone as a lever and manually check the route, as described above. There is a great deal of difficulty in ensuring the safety of the route structure.

An object of the present invention is to solve the above-mentioned conventional problems. In other words, it is possible to open an arbitrary route and display a signal, such as a relief train, which is not predefined in the interlocking chart, with a simple operation. It is an object of the present invention to provide a signaling system interlocking device that can ensure security.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a signal-based interlocking device using a route track circuit. Therefore, in order to detect the presence of trains, etc., route reservation information including route setting reservation information and track presence information for that section is registered for each track circuit that is set by dividing the track into multiple sections. A track section reservation table that defines the connection relationship between track circuits, switch machines, and their switching positions, and a track circuit link table that specifies the connection relationship between track circuits, switch machines, and their switching positions, and a track circuit link table that specifies the connection relationship between track circuits, switch machines, and their switching positions, and a track circuit link table that specifies the connection relationship between track circuits, switch machines, and their switching positions, and a track circuit link table that specifies the connection relationship between track circuits and switch machines and their switching positions. and a route setting request input means for specifying and inputting a route track circuit including a destination track circuit and a destination track circuit; Search the track circuit link table, and if they are consecutive, search the track circuit reservation table to check whether there are reservations for other trains, etc. for the route track circuit in question, and check whether reservations are made for all route track circuits. If not, the switch connecting the route track circuit and its switching position information are extracted from the track circuit link table, and the switching command for the corresponding switch is issued to the switch control means according to the extracted information. a route creation means for maintenance vehicles, etc., which outputs the route track circuit and registers the route track circuit in the track circuit reservation table, and also outputs the opening information of the route consisting of the route track circuit; The present invention is characterized by comprising a display means for displaying that the route according to the route setting request has been configured.

[Function] With this configuration, according to the present invention, the above object is achieved by the following function.

Basically, the present invention introduces the concept of track circuit reservation as an interlocking control method, and makes conflict judgments regarding the course, work scope, etc. related to course setting requests based on the presence or absence of course reservations set for each track circuit. Direct track circuit reservation control eliminates conflict judgments that can be dangerous in the operation of trains, etc.
This can be realized using simple and clear interlocking control logic.

In particular, by simply inputting a route setting request input means such as a computer terminal, wireless terminal, or telephone connection terminal, by specifying and inputting the route track circuit related to the course of a train, etc., the track circuit link table is searched and the route is connected. The validity of the track circuit is checked, and the track circuit reservation table is searched to check whether there is a conflict.Furthermore, according to the contents specified in the track circuit link table, a direct conversion command is output to the corresponding switch machine. , the path of the request is configured. Additionally, by registering a reservation for the route track circuit in the track circuit reservation table, subsequent route configurations of other trains, etc. are substantially prohibited, thereby ensuring security. Further, in order to show the opening of the route consisting of the route track circuit to related parties such as workers, the opened route track circuit is output and displayed in a graphic display or the like on a display device provided in the terminal or the like. As a result, workers and other related parties can easily and easily recognize the opening of a route without relying on traffic lights or signs erected on the ground. Furthermore, it is possible to construct a route without any traffic lights or signs.

As described above, according to the present invention, in response to a request for setting an arbitrary route that is not specified in the interlocking diagram, route reservations for other normal train operations, reservations for shunting work sites, reservations for maintenance work sites, etc. Setting requests such as reservations for emergency operations and reservations for the suspension range of operation safety equipment can be commonly managed on a track circuit basis.

Therefore, even if you arbitrarily set or change the work range designation for maintenance and shunting work, the route setting and opening of maintenance vehicles, the range of shunting work, or the route for emergency operation, all other trains Since it is possible to determine whether there is a competitive relationship with other systems, it is possible to not only expand the scope of interlocking control objects, but also to create a highly flexible system. Note that these settings or changes can be realized without adding or changing any special control logic, such as adding or changing the 1j relay circuit or spur file.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of an embodiment of a signal-based interlocking device using a route track circuit according to the features of the present invention. As shown in the figure, this device includes a terminal such as a computer or a wireless device], a route creation means 2 for maintenance vehicles, etc., which creates an arbitrary route for maintenance vehicles, emergency trains, etc., and a track circuit reservation table 3. It is configured to include a track circuit link table 4 and a switch control means 5. The terminal 1 includes a route setting request input means IA and a display means IB.

The maintenance vehicle route creation means 2, the track circuit reservation table 3, and the track circuit link table 4 are configured by a computer. The point machine control means 5 is adapted to drive and control the point equipment 6.

The detailed configuration and operation of the embodiment configured as described above will be described next. In explaining the details of this embodiment, the explanation will be made with appropriate reference to an example of track wiring in a station premises, which is schematically shown in FIG. 2. The illustrated wiring type represents only a double-track down line, and trains normally travel from the N direction to the S direction. This down line is branched into down main line 1RAT and down line 1 I RBT by switch machines 51 and 61, and is further branched from track circuit 62T connecting to the down main line to switch machine 6.
As shown in the figure, the base line is branched by a plurality of track circuits 51T and IRAT.

It is divided into IRBT, 61T, 62T, 5RET, etc. This track circuit applies voltage between a pair of rails in that section, and when a train, etc. enters that section,
It detects when the rails are shortened by wheels to detect trains, etc. on the track. Additionally, the track circuit is originally a section for controlling switches and traffic lights, and is divided into sections suitable for such control. For example, in a place where there is a switch, one section is set across the switch. Then, on the approach side of the track circuit 51T, an in-house signal IRA indicating the opening of the route on the downbound main line side and an in-house signal IRB indicating the opening of the route on the downbound No. 1 side are installed. Furthermore, a departure signal 5RE indicating the opening of the route for the switch 61 is installed on the exit side of the track circuits IRA and T of the down main line. On the exit side of the track circuit I RBT on the 1st outbound track, there is a departure signal 6RE indicating the opening of the route for the switch 61.
is installed. In addition, switching marks 151L1, 52L,...
21R, 22R, 23L, and 24L are installed. In addition, the area Y surrounded by the dotted chain line in the figure is an example of the maintenance work site (Nakaho-10).

The track circuit reservation table 3 shows the reservation status of which track circuit is used by the currently set or configured course or maintenance/replacement work range. For example, as shown in Figure 3, this table 3 has columns corresponding to all track circuits, and information such as the number of the route or work that has been set or configured is registered in the column of the corresponding track circuit. be done. Therefore, when a request for route setting, etc. is made, a competition judgment can be made based on whether the route number, etc. of another train, etc. is registered in the related route track circuit column. Further, although not shown, a column is provided for storing information on whether a train or the like is present on each track circuit and identification information such as a train number. In the example in Figure 3, maintenance work (Life Insurance-10) is track circuit IRAT, 61T, 62T.
, 5RET. Therefore, even if a request is made to set the route lRA for train A, that route cannot be taken.

The track circuit link table 4 is a table that defines the connection relationship between the track circuit, the switch machine, and its switching position, and as shown in FIG. It has become.

In the figure, the symbol C added to the switch 51, etc. is a common line,
N is [orientation J, R is "reverse position".

FIG. 5 shows a processing flowchart of the route creation means 2 for maintenance vehicles, etc. As shown in the figure, in step 161, it is assumed that, for example, a work site (life insurance 10) for use of a maintenance vehicle is specified from the route setting request input means IA of the terminal 1.

This designation is performed by designating the related track circuit from the maintenance vehicle's starting point to its destination as the route track circuit.

In the example in Figure 2, the route track circuit is 5RET, 62T
, 61. T, IRA, T. The maintenance vehicle route creation means 2 that has received this designation checks whether or not these route track circuits are continuous in the track circuit link table 4 (step 62). This prevents route conflicts midway through the route due to input errors. If the routes are continuous, the track circuit reservation table 3 is searched, and those route track circuits are used for other trains, etc., such as other main line routes (IRA, 5RE, 6RE, etc.) or shunting routes (21
R, 22R, 23L, 24L), etc., are not registered or not (step 163). Further, when track location information is registered in the track circuit reservation table 3, it is also checked whether there are any other trains or the like on the route track circuit. If no other trains are reserved or on the line, the track circuit link table 4 is searched to extract the numbers and switching positions of switch machines related to route opening (step 164).

According to the extracted contents, a switch switching command is output to the switch control means 5 (step 165). In response to this diversion command, device information constituted by the switch equipment 6 is taken in via the switch control means 5 to confirm that the route has been opened. Subsequently, regarding the above-mentioned route track circuit, the work number of the maintenance vehicle (Life Insurance -10) is registered in the corresponding column of the track circuit reservation table 3 as shown in FIG. As a result, route requests from other trains, etc. are excluded, and the route is essentially locked. Note that the route number shown in parentheses in FIG. 3 is an example in which a request for setting a career path is excluded if (Life Insurance-10) is registered. After securing the maintenance work site in this way, a route opening display is displayed on the display means IB of the terminal 1, such as a computer terminal, a wireless terminal, a telephone connection terminal, etc. In the case of a display means that displays a route wiring diagram, this method of displaying the opening may include changing the display color of the track circuit that has been opened from red to green, or flashing the display.

In addition, if you do not want to display the route wiring diagram, click "Route opening ○
Characters such as "K" or "Route open from r5RET (initiation) to IRAT (arrival point)" are displayed, and these displays have the same meaning as the display of traffic lights.

Although not shown in FIG. 5, when the maintenance vehicle completes moving to a predetermined location or is accommodated on the base line, the terminal 1 specifies the signal type and route track circuit information, When a route cancellation request is input, the maintenance vehicle route (life insurance-10) in the track circuit reservation table 3 is deleted, and
Restoring the display on the display means. This essentially unlocks the route and allows other trains to set their own routes.

As explained above, according to this embodiment, a route setting request input means such as a cosiputer terminal, a wireless terminal, or a telephone connection terminal is used to specify and input a route track circuit along the course of a train, etc. , search the track circuit link table to check the validity of the route connection, search the track circuit reservation table to check whether there is a conflict, and further check the corresponding transfer according to the contents specified in the track circuit link table. The required route is configured by directly outputting a conversion command to the machine. Additionally, by registering a reservation for the route track circuit in the track circuit reservation table, subsequent route configurations of other trains, etc. are substantially prohibited, thereby ensuring security. Further, in order to show the opening of the route consisting of the route track circuit to related parties such as workers, the opened route track circuit is output and displayed in a graphic display or the like on a display device provided in the terminal or the like. the result,
Workers and other related parties can easily and easily recognize the opening of a route without relying on traffic lights or signs erected on the ground. Furthermore, it is possible to construct a route without any traffic lights or signs. Therefore, it is possible to open any route that is not predefined in the interlocking chart, such as for a relief train, and to display a signal with a simple operation, and safety can be ensured.

Note that the format of the track circuit link table 4 is not limited to the above-mentioned embodiment, and may be any format as long as it defines the relationship between the track circuit, the switch machine, and its switching position.

In addition, if the track circuit detection means can detect the presence or movement of a train, etc., when a train, etc. enters the set route, the display on the terminal changes from "route opening display" to "route passing status display". , and when the destination is reached, the display can be returned to the state before the route request.

(Effects of the Invention) As explained above, the present invention has the following effects.

That is, the present invention introduces the concept of track section reservation as an interlocking control method, and directly performs conflict judgments on courses and work ranges related to course setting requests based on the presence or absence of course reservations set for each track section. Since track section reservation control has been adopted, conflict judgments that can be dangerous in the operation of trains, etc. are avoided.
It can be realized by simple and clear interlocking control logic.

In particular, by simply inputting a route setting request input means such as a computer terminal, wireless terminal, or telephone connection terminal, by specifying and inputting the route track circuit related to the course of a train, etc., the track circuit link table is searched and the route is connected. The validity of the track circuit is checked, and the track circuit reservation table is searched to check whether there is a conflict.Furthermore, according to the contents specified in the track circuit link table, a direct conversion command is output to the corresponding switch machine. , the path of the request is configured. Additionally, by registering a reservation for the route track circuit in the track circuit reservation table, subsequent route configurations of other trains, etc. are substantially prohibited, thereby ensuring security. Further, in order to show the opening of the route consisting of the route track circuit to related parties such as workers, the opened route track circuit is output and displayed in a graphic display or the like on a display device provided in the terminal or the like. As a result, workers and other related parties can easily and easily recognize the opening of a route without relying on traffic lights or signs erected on the ground. Furthermore, it is possible to construct a route without any traffic lights or signs.

As described above, according to the present invention, in response to a request for setting an arbitrary route that is not specified in the interlocking diagram, route reservations for other normal train operations, reservations for shunting work sites, reservations for maintenance work sites, etc. Since it is possible to determine the conflicting relationship with setting requests such as reservations for emergency operation and reservations for the suspension range of operation safety equipment, any route not specified in the interlocking chart can be configured with a high degree of security. Furthermore, since no manual work is required, the work becomes easier and safety is ensured from this aspect as well. Moreover, for routes that are not regularly used,
Since there is no need to stipulate the interlocking chart, the creation of the interlocking chart and coordination with the operator become extremely easy.
