Description

  The present invention relates to a train control device, and more particularly to a train control device having excellent noise resistance.

  In recent years, in order to reduce train operation intervals and improve ride comfort, on the basis of predetermined digital information (ATC information) obtained from the ground, a speed check pattern is mainly generated on the vehicle (train), There has been proposed a one-stage control digital ATC system train control apparatus that performs train speed control using the generated speed check pattern (see Non-Patent Document 1). The train control device according to the one-step control digital ATC system always uses predetermined information (data) obtained from the ground side and predetermined information (data) such as track circuit permutation data stored in advance in the on-board device. Thus, a single parabolic speed check pattern from the current position to the stop target point can be generated.

  The on-board device of the above-mentioned one-stage control digital ATC system train control device is based on the data from the ground unit installed at a predetermined interval on the rail on which the train travels, and the ground side is the main component. Because it is a technique similar to the ATS-P type multi-stage control method for generating a step-like speed check pattern corresponding to the above, a signal (information) from the ground side similar to a well-known ATS-P type on-board device is used. It is comprised by various processing parts, such as the receiving part which receives, and the speed and position detection part which detects the speed and position of the own train.

By the way, the one-stage control digital ATC system train control device that mainly generates the speed check pattern mainly on the vehicle upper side according to the above proposal has predetermined data obtained from the ground side at all times and predetermined data stored in advance in the on-vehicle device. The predetermined speed check pattern is generated on the basis of the data, but if the predetermined information from the ground side cannot be obtained continuously for the predetermined measurement time due to noise or the like, the emergency brake is assumed to have occurred. It is configured to operate.

  The train control device of the one-stage control digital ATC system that mainly generates the speed check pattern based on the above-mentioned proposal has excellent features such as reduction of train operation interval and improvement of ride comfort. For example, when a short or short track circuit with a short travel distance is included in the running track circuit, for example, it includes a branching section, there is no time to receive complete information from the short track circuit and the information from the next track circuit is not received. Reception may occur. In this case, since the information from the short track circuit is missing, it does not match the track circuit permutation data stored in advance by the train, and the received information is regarded as noise. The emergency brake will operate if the predetermined information cannot be obtained during the measurement time.

  Therefore, an object of the present invention is to provide a train control device capable of continuously operating a train even if the track circuit includes a short track circuit.

  In order to achieve the above object, the train control device according to the present invention generates predetermined train control information based on predetermined information that is always obtained from a running track circuit.

It is characterized by doing.
The train control device according to claim 4 of the present invention is characterized in that the generated predetermined train control information is a predetermined speed check pattern.

Even so, train operation can be continued, and noise resistance can be improved.

The train control device according to claim 2 of the present invention includes an extraction means for extracting information relating to a track circuit into which a train enters next from predetermined information stored in advance in the train, and in the extracted information When the predetermined information indicating that the next track circuit is a predetermined short track circuit is included, the short track circuit is included in the track circuit. Even if it is included, the operation of the train can be continued and the noise resistance can be improved.
The train control device according to claim 3 of the present invention determines that the train has passed through the short track circuit when predetermined information is obtained from the track circuit next to the short track circuit with a predetermined measurement time extended. Therefore, the passing track circuit can be accurately recognized.
In the train control device according to the fourth aspect of the present invention, since the predetermined train control information to be generated is a predetermined speed check pattern, the speed check pattern can be effectively generated on the vehicle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a train control device according to an embodiment.

  A train (vehicle) A traveling on the rail R is equipped with an onboard device B for realizing the train control device of the present invention. This on-board device B is provided with predetermined ATC information obtained from the rail R, that is, the track circuit, or predetermined position information from a ground element (not shown) via an upper element (antenna) a provided at the lower part of the head of the train A. Receiver 4 formed to include an amplifier circuit, a filter circuit, and the like for receiving the signal, and predetermined information (data) obtained from the ground side, and predetermined information stored in advance in the memory M. From the calculation unit 2 that generates a predetermined speed check pattern based on the information (data), and the output unit 3 that is formed by a relay logic unit and can drive and control devices (not shown) such as a brake It is configured.

  In FIG. 1, G is a speed generator provided on the axle of train A, and a signal (pulse signal) obtained from the speed generator G is input to the calculation unit 2. Yes. In addition, the memory M includes predetermined information for generating a predetermined speed check pattern in the on-board device (operation unit 2), such as track circuit permutation data, track circuit attribute data (track circuit ID data), Route information such as branch data and gradient data is stored in advance.

  A ground transmitter (not shown) is connected to the starting end side of the rail R forming the track circuit (the right end side of the rail R in FIG. 1), and predetermined information such as track circuit attribute data is applied. Predetermined position information is transmitted from a ground element (not shown) installed at a predetermined interval along the track circuit. Therefore, when the train A passes through the ground element, the speed check pattern generated by detecting the absolute position of the own train can be corrected.

  The control operation will be described below with reference to the explanatory diagram of FIG. 2A and the flowchart of FIG. Now, it is assumed that the train A is traveling from the track circuit 1T in the direction of the track circuit 4T (step 100 operation; hereinafter, step is referred to as “S”). Of these track circuits 1T to 4T, the track circuit 3T is formed as a short track circuit having a shorter travel distance than the general track circuits of the other track circuits 1T, 2T, and 4T.

  While traveling on the track circuit 1T, the train A generates a predetermined speed check pattern based on the predetermined information obtained from the track circuit 1T and the predetermined information stored in the memory M in advance. The train i is operated using the speed check pattern (S102, S104). That is, while the train A is traveling on the track circuit 1T, the speed generator G grasps the own train position and the own train speed in the track circuit 1T, so the generated speed check pattern, the own train position, and the own train are detected. Depending on the speed, operation is performed in accordance with the speed check pattern. During this operation, a timer related to the measurement time processing of the present invention (not shown) included in the calculation unit 2 is repeatedly started. That is, the timer is reset after measuring a predetermined time, and the operation of starting the time measurement again is performed. The predetermined measurement time is normally set to 8 message lengths sent from the track circuit toward the vehicle. If no normal train control message is received within the predetermined measurement time, the emergency brake is activated to ensure safety (no S102).

  When the progress of the train A enters the track circuit 2T, the predetermined information transmitted from the track circuit 2T onto the vehicle includes predetermined information indicating that the next track circuit (3T) is a short track circuit. Therefore, the on-board device B can recognize that the next track circuit (3T) is a short track circuit.

  When it is recognized that the next track circuit is a short track circuit on the vehicle (S106 short track circuit), the set time of the above-mentioned timer is a predetermined extended measurement time slightly longer than the normal measurement time, For example, the message length is set to 10 (S108). Therefore, the train A can continue traveling for the extended measurement time without obtaining predetermined information from the track circuit. Train A enters the track circuit 4T, and predetermined information is received from the track circuit 4T. Since the predetermined information includes information (track circuit attribute data) indicating the track circuit 4T, the control unit 2 recognizes that the own train (train A) has entered the track circuit 4T. At the same time, even if predetermined information from the previous track circuit 3T is not obtained, it is determined that the previous track circuit 3T has passed safely on the condition that the measurement time of the timer is extended, and the train I will continue to operate. Then, the set time of the timer is returned to the normal measurement time. Of course, even when the measurement time of the timer is extended, if predetermined information is obtained from the short track circuit 2T, the control process is performed as usual and the traveling of the train A is continued.

  When the train A passes between the general track circuits such that the track circuit 1T advances from the track circuit 1T to the track circuit 2T, the measurement time of the timer is not extended (S106 general track circuit, S110). Therefore, for example, when the predetermined information cannot be received from the track circuit 2T within a predetermined measurement time after the predetermined information from the track circuit 1T is interrupted, the emergency brake is activated because an abnormality has occurred.

  FIG. 3A is an explanatory diagram of a train control apparatus according to another embodiment of the present invention, and FIG. 3B is a flowchart showing the control operation. The configurations of the track circuits 1T to 4T shown here are the same as those shown in FIG. Here, the track circuit 3T is determined as a short track circuit from the route information stored in the memory M of the train A in advance, and the timer is extended (S206 short track circuit, S208). Accordingly, in this case, information indicating that the next track circuit 3T is a short track circuit is not included in the information sent from the track circuit 2T toward the vehicle.

  The train control operations such as the timer extension process or emergency brake output process shown in FIGS. 3 (a) and 3 (b) are the same as those in FIGS. 2 (a) and 2 (b). Omitted. Note that the step numbers in FIG. 3B and the step numbers in FIG. 2B correspond to each other only with a difference between the 100s and the 200s.
