Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to operation management of trains and vehicles (hereinafter collectively referred to as trains), train replacement work management, maintenance vehicles and maintenance work relations,
Or, it relates to a railway management system that manages emergency driving in an emergency. Specifically, in accordance with a given route setting request, a rolling track provided at a branch portion of a railway line (hereinafter referred to as a track). The present invention relates to an exercise device that switches a machine to open a desired path and automatically performs an operation of displaying the opening of the path on a traffic light.

[Conventional technology]

In locations where train tracks are complicated and branched, such as inside railway stations, open the train tracks, such as turning machines, traffic lights, and signs, and display whether or not to enter the train tracks. A large number of devices (hereinafter collectively referred to as route control devices) are provided, and these are switched according to arrival, departure, passage, etc. of trains and maintenance vehicles (hereinafter collectively referred to as trains), and routes required by the train. Is being opened. The switching operation of these route control devices must be carried out promptly and appropriately in response to arrival, departure, passage, etc. of the train, and the train must be operated or passed efficiently. Moreover, there should be no mistake in the operation of these route control devices, and if only the attention of the operator is used to prevent the erroneous operation, there is a risk of erroneous operation as trains start and stop frequently. On the other hand, work efficiency does not increase. Therefore, when the operation of the route control equipment is wrong, in order to eliminate the erroneous operation to secure the safety and to improve the work efficiency, the interlock (chain) is preliminarily set in the operation relation of the plurality of related route control equipment. An interlocking device that sets a lock and performs a control operation according to the setting is adopted.

That is, in the interlocking device, first, when the operator inputs data such as the starting and ending points of the train in accordance with the route setting request,
In response to this, it checks (checks) whether the related route has already been set and opened by another train, and after confirming that it has not been set, the rolling machine necessary to open the requested route. Is output in the predetermined direction. Next, it is confirmed that the predetermined route has been opened based on the conversion position signal output from the rolling machine, and this is displayed on the display panel of the interlocking device control panel. After setting the route in this way, the operation and work of other trains that obstruct the route are disabled, and in order to secure the route until the train passes, the chain is linked to the related rolling machines. Outputs a lock command. Then, using the track circuit detection means, confirm that no other train is on the route, switch the display of the relevant traffic light to the "progress (blue)" side, lock it, and lock it on the display panel. indicate. Then, after the train has completed passing through a predetermined point on the set route, the lock of the rolling machine or the like is released. In this way, the operator can enter the data such as the starting and ending points of the train, etc., and the route will be automatically opened without conflict and the necessary display will be performed, so that erroneous operation etc. can be prevented. , Frequent train arrivals and departures can be handled efficiently.

Conventionally, as an interlocking device having such a function, a relay interlocking device having an interlocking control logic formed by a relay circuit, and an electronic interlocking device using a microcomputer are known. In the former relay-type interlocking device, a lock is applied between the turning device and the traffic signal within the control target range and the traffic signals in consideration of all combinations, thereby covering the erroneous operation on the dangerous side and preventing the malfunction. It is basically to prevent. In addition, the route setting is performed by using the start / end lever push button or the signal lever, and the competition of the train route during the opening operation is eliminated by the route selection circuit or the lever relay circuit assembled by the relay circuit, and the relationship is changed. An indirect competitive judgment system is adopted, such as eliminating through a rolling machine by a machine lock or a route lock mechanism.

[Problems to be Solved by the Invention]

However, the conventional interlocking device has a relay circuit and a spur file based on interlocking control data called a motion chart, and it is difficult to configure an arbitrary path not specified in the operation chart. is there. In other words, the interlocking diagram defines the route that uses the on-site / departure signal, the guidance signal, the interchange signal, or the interchange sign as an index, and the interlocking control of the interlock etc. of the route control device is made corresponding to the specified route. Since the conditions are defined in the interlocking chart and the train is operated based on the course and interlocking control conditions defined in the interlocking chart, it is difficult to construct an arbitrary track.

Therefore, in the case of emergency operation in which a rescue train for indexing a failed vehicle to a depot, etc. is driven by a normal main line on the reverse line, such routes and departure signals are not specified in the interlocking chart. , It is necessary to manually switch the rolling machine with a handwheel, to lock the rolling machine, and to show a progress signal to the flight crew by a flag signal. There is a problem that such manual conversion and locking of a turning machine requires skill and daily training and sufficient experience are required in order to handle abnormalities in a short time. .

In addition, the above problems also apply when the train cannot be stopped at a predetermined position and overruns beyond the traffic light, when the train retreats, or when it is in an emergency operation such as when moving forward. is there.

Also, when driving a maintenance vehicle, if the route is not set in advance, the only way to handle the turning machine is to check the route manually, as described above. There is a great deal of difficulty in the security of the course structure.

An object of the present invention is to solve the above-mentioned conventional problems. In other words, it is possible to realize an arbitrary course not prescribed in advance in the interlocking chart such as a rescue train by a simple operation, and to ensure safety. To provide a device.

[Means for Solving the Problems]

In order to achieve the above object, the interlocking device of the present invention comprises a computer (2, 3, 4), a terminal (1), a switching machine control means (5), and a signal transmission path connecting these. And the computer has a route preparation means (2), a track circuit reservation table (3) and a track circuit link table (4), and the terminal displays a route setting request input means (1A) and a display. Means (1B).

Here, the track circuit reservation table (3) is for registering reservation information relating to the course setting of the train, and the registration is a track circuit section divided along the track to detect the position of the train on the track. It is done in units.

The track circuit link table (4) defines the wiring shape of the line, and the wiring shape is defined by the interconnection relationship of the track circuit sections and the switching direction of the rolling machine.

The route setting request input means (1A) inputs the route setting request by designating all the track circuit sections of the route including the developed track circuit section of the train, the intermediate track circuit section and the destination track circuit section. To do.

The route creating means (2) receives the route setting request input from the route setting request inputting means (1A), searches the track circuit link table (4) in response to the input, and specifies it by the route setting request. It is determined whether or not the track circuit section of the route that has been performed is continuous (162). If the result of the determination is that the track circuit section of the route is continuous, the track circuit reservation table (3) is searched, and the reservation information related to other trains is registered for the track circuit section of the route. Whether or not there is a route conflict is determined (163). When the result of the judgment is not a route competition, the rolling machine and its switching direction included in the route are read from the track circuit link table (4) and output to the rolling machine control means (5). Yes (164,165). Further, the track circuit section of the route is reserved and registered in the track circuit reservation table (2) (166). Further, the opening information of the route according to the route setting request is output (167).

The turning machine control means (5) takes in the turning machine and its changing direction output from the course creating means (2) and outputs a change command to the corresponding turning machine to request a course setting. Open the path.

The display means (1B) takes in the opening information output from the path creating means (2) and displays that the path relating to the path setting request has been opened.

[Action]

With such a configuration, according to the present invention, the above object is achieved by the following actions.

Basically, the present invention has introduced a concept of track circuit reservation as a method of interlocking control, that is, a concept of making a course setting reservation for each section of a track circuit set on a track. In this way, since the race circuit reservation control is performed which directly determines the competition of the route and the work range, etc. required for the route setting request based on the presence / absence of the route reservation set for each track circuit, there is a danger in train operation. The competition judgment can be realized by a simple and simple interlocking control logic.

In particular, by simply specifying and inputting a route track circuit related to the route of a train or the like from a route setting request input means such as a computer terminal, a wireless terminal, or a telephone connection terminal, the track circuit link is performed by the function of the route creating means. The table is searched to confirm the adequacy of the route connection, the track circuit reservation table is searched to check whether there is a conflict, and further, according to the contents stipulated in the track circuit link table, the corresponding rolling machine is selected. A direct conversion command is output to configure the route of the request. In addition, by additionally registering the route track circuit in the track circuit reservation table, the route configuration of other trains thereafter is substantially prohibited, and security is ensured. Further, in order to show the opening of the route formed by the route track circuit to a person concerned such as an operator, the opened route track circuit is output and displayed on the display device provided in the terminal or the like. As a result, a person concerned such as a worker can easily and easily recognize the opening of the route without relying on the traffic lights and signs built on the ground. Moreover, it is possible to configure a route without traffic lights or signs.

As described above, according to the present invention, for any route setting request that is not defined in the interlocking chart, route reservation of operation of other normal trains, reservation of replacement work site, reservation of maintenance work site, It is possible to commonly manage reservation requests for emergency operations, setting requests for reservations of stoppage areas for operation and safety equipment, etc. on a track circuit basis. Therefore, even if the work range for maintenance / replacement work is specified, the route of maintenance vehicles is set / opened, the range of replacement work, or the route for emergency operation is arbitrarily set or changed, all other trains Since you can judge the competitive relationship with
Not only will the range of linked control be expanded, but a highly flexible system will be possible. Note that those settings or changes can be realized without adding or changing special control logic, such as adding or changing a relay circuit or a 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 signaling interlocking device using a path track circuit according to the features of the present invention. As shown in the figure, this device includes a terminal 1 such as a computer and a wireless device, a maintenance vehicle etc. route creating means 2 for creating an arbitrary route such as a maintenance car or an emergency train, and a track circuit reservation table 3. The track circuit link table 4 and the rolling machine control means 5 are included. The terminal 1 includes a route setting request input means 1A and a display means 1B. The maintenance vehicle etc. route creating means 2, the track circuit reservation table 3, and the track circuit link table 4 are configured by a computer. The rolling machine control means 5 drives and controls the rolling machine group 6.

The detailed configuration and operation of the embodiment thus configured will be described below. In describing the details of the present embodiment, an example of the track wiring in the station yard shown in the schematic view of FIG. The wiring type shown in the figure represents only a double-track down line, and a normal train progresses from N direction to S direction. This down line is the down line main line by the turning machines 51 and 61.
The base line is branched by a rolling machine 62 from a track circuit 62T which is branched to 1RAT and 1RBT of down line 1 and which is connected to the down line. As shown in the figure, the track has a plurality of track circuits 51.
It is divided into T, 1RAT, 1RBT, 61T, 62T, 5RET, etc. This track circuit applies a voltage between a pair of rails in that section, and when a train or the like enters the section, it detects that the rails are shortly dropped by wheels, and This is to detect the on-rail. Further, the track circuit is originally a section for controlling a turning machine and a traffic signal, and is divided into sections suitable for performing such control. For example, where there is a rolling machine, one section is set across the rolling machine. Then, on the approach side of the track circuit 51T, an on-site traffic signal 1RA indicating the opening of the route on the down main line side and an on-site traffic signal 1RB indicating the opening of the route on the down line 1 side are installed. Further, a departure signal 5RE is installed on the exit side of the track circuit 1RAT of the down main line to indicate the opening of the route of the rolling machine 61. On the other hand, on the exit side of the track circuit 1RBT on the down line No. 1, a departure signal 6RE indicating the opening of the course of the rolling machine 61 is installed. Also, rolling machines 51 and 6
Swap signs 51L, 52L, 21R, 2 at both ends of the track circuit including 1 and 62
2R, 23L, 24L are installed. A range Y surrounded by a chain line in the figure is an example of a maintenance work site (Nakaho-10).

The track circuit reservation table 3 shows the reservation status of which track circuit is being used by the currently set or configured route or maintenance / replacement work range. For example, as shown in FIG. 3, this table 3 has columns corresponding to all the track circuits, and information such as the number of the route or work set or configured is registered in the corresponding track circuit column. To be done. Therefore, when there is a request for route setting or the like, it is possible to make a competition determination based on whether or not the route number of another train or the like is registered in the column of the related route track circuit. Although not shown, each track circuit is provided with a column for storing information as to whether or not a train or the like is present and identification information such as a train number. In the example of FIG. 3, maintenance work (Nakaho-10) is reserved for the track circuits 1RAT, 61T, 62T and 5RET. Therefore, even if the setting request for the route 1RA of the train A is made, the route cannot be taken.

The track circuit link table 4 is a table that defines the connection relationship between the track circuit and the rolling machine and its conversion position. As shown in FIG. 4, it is a conceptual table simulating the wiring diagram of FIG. Has become. In the figure, the symbol C added to the rolling machine 51 and the like is a common line, N is "localize", R is "reverse"
Is.

FIG. 5 shows a processing flow chart of the route preparation means 2 for a maintenance vehicle or the like. As shown, in step 161,
It is assumed that, for example, a work site (Nakaho-10) associated with the use of a maintenance vehicle is designated from the route setting request input means 1A of the terminal 1. This designation is performed by designating a related track circuit from the starting point to the ending point of the maintenance vehicle as a route track circuit. In the example of Fig. 2, the path trajectory circuit is 5RET, 6
It is 2T, 61T, 1RAT. Upon receiving this designation, the maintenance vehicle etc. route creating means 2 confirms whether or not these route track circuits are continuous in the track circuit link table 4 (step 162). As a result, it is possible to prevent a route conflict on the way of the route due to an input error. And if they are continuous,
The track circuit reservation table 3 is searched, and the route of another train or the like of the route track circuit, for example, another main line route (1RA, 5RE, 6R
It is confirmed whether or not the setting such as E) or the exchange route (21R, 22R, 23L, 24L) is not registered (step 163).
Further, when the on-rail information is registered in the track circuit reservation table 3, it is also confirmed whether or not another train or the like of the route track circuit is on the line. If there are no reservations for other trains and there are no trains present, the track circuit link table 4
Is searched to extract the number and turning position of the turning machine related to the opening of the route (step 164). In accordance with the extracted contents, the switching machine control unit 5 outputs a switching machine conversion command (step 165). In response to this conversion command, the position information output from the rolling machine group 6 is taken in through the rolling machine control means 5 and it is confirmed that the route has been opened. Then, for the above route track circuit, the work number (Nakaho-10) of the maintenance vehicle is registered in the corresponding column of the track circuit reservation table 3 as shown in FIG. As a result, the route request of other trains is eliminated, and the route is locked substantially. The route number shown in parentheses in FIG. 3 is an example in which the route setting request is excluded when registration of (Nakaho-10) is made. After the maintenance work site is secured in this way, the route opening display is performed on the display means 1B of the terminal 1 such as a computer terminal, a wireless terminal, and a telephone connection terminal. As the method of displaying the opening, in the case of the display means displaying the schematic diagram of the route wiring, the display color of the opened track circuit can be changed from red to green, or the display can be flashed. Also, if you do not display the route wiring schematic,
Characters such as "Route opening OK" or "Route opening from 5RET (starting point) to 1RAT (ending point)" are displayed, and these indications have the same meanings as those of the traffic lights.

Although not shown in FIG. 5, when the maintenance vehicle is completely moved to a predetermined place or accommodated in the base line, the signal type and the route track circuit information are designated from the terminal 1, When the route cancellation request is input, the maintenance vehicle route (Nakaho-10) in the track circuit reservation table 3 is erased and the display of the display means is restored. This substantially unlocks the route lock and enables the route setting of another train or the like.

As described above, according to the present embodiment, it is only necessary to specify and input the route track circuit related to the route of the train or the like from the route setting request input means such as the computer terminal, the wireless terminal, or the telephone connection terminal. , The track circuit link table is checked to confirm the adequacy of the route connection, the track circuit reservation table is searched to check whether there is competition, and the corresponding transfer is performed according to the contents specified in the track circuit link table. The conversion route is directly output to the Tetsuki to construct the required route. Also, by registering the route track circuit in the track circuit reservation table together,
Security is secured by substantially prohibiting the course composition of other trains after that. Further, in order to show the opening of the route formed by the route track circuit to a person concerned such as an operator, the opened route track circuit is output and displayed by a graphic display on a display device provided in the terminal or the like. As a result, a person concerned such as a worker can easily recognize the opening of a route in an easy-to-understand manner without relying on a traffic light or a sign built on the ground. Moreover, it is possible to configure a route without traffic lights or signs. Therefore, it is possible to realize opening of a route and signal indication which are not specified in advance in the interlocking chart such as a rescue train by a simple operation, and security can be secured.

The form of the track circuit link table 4 is not limited to the above-mentioned embodiment, but any form may be used as long as it defines the relationship between the track circuit and the rolling machine and its conversion position.

In addition, if the track circuit detection means can detect the presence or movement of a train, etc., when the train, etc. enters inside the set course, the terminal display will change from "course opening display" to "course passing state". The display can be changed to "display" and the display can be returned to the state before the course request when the arrival point is reached.

〔The invention's effect〕

As described above, the present invention has the following effects.

That is, the present invention introduces the concept of track section reservation as a method of interlocking control, and directly judges the competition of the track and work range required for the track setting request based on the presence or absence of track reservation set in track section units. Because of the track section reservation control, there is a risk of competing judgments in the operation of trains, etc.
It can be realized by a simple and clear interlocking control logic.

Especially, by specifying and inputting the route track circuit related to the route of the train from the route setting request input means such as a computer terminal, a wireless terminal, or a telephone connection terminal, the track circuit link table is searched and the route connection is established. In addition to confirming the adequacy of the above, the track circuit reservation table is searched to check whether there is any conflict, and further, according to the contents specified in the track circuit link table, a direct conversion command is output to the corresponding rolling machine. , The course of the request is configured. In addition, by additionally registering the route track circuit in the track circuit reservation table, it is possible to substantially prohibit the subsequent route configuration of other trains, etc., and to ensure safety. Further, in order to show the opening of the route formed by the route track circuit to a person concerned such as an operator, the opened route track circuit is output and displayed on the display device provided in the terminal or the like. As a result, a person concerned such as a worker can easily recognize the opening of the route without relying on the traffic lights and the signs built on the ground. Moreover, it is possible to configure a route without traffic lights or signs.

As described above, according to the present invention, for any route setting request that is not defined in the interlocking chart, route reservation of operation of other normal trains, reservation of replacement work site, reservation of maintenance work site, Since it is possible to determine a competitive relationship with a setting request such as a reservation for an emergency operation or a reservation for a use stop range of the operation security equipment, it is possible to configure an arbitrary path not specified in the interlocking chart with a high degree of security. In addition, since there is no manual work, the work is simplified and the security is secured from this aspect. In addition, since it is not necessary to specify in the interlocking chart for routes that are not regularly used, it is extremely easy to create the interlocking chart and coordinate with the operator.
