  However, in the train control apparatus according to the above-mentioned proposal, the train control device according to the one-step control digital ATC system does not store the current position of the own train in the track circuit at the time of starting the train operation such as the return section of the train. There is an inconvenience that the train position cannot be recognized and the speed check pattern cannot be generated.

  Therefore, the present invention has been made to solve the above-described inconveniences, and the purpose of the present invention is to safely check the speed even if the current position of the own train in the track circuit cannot be recognized, such as in the turn-around section. An object of the present invention is to provide a train control device capable of generating a pattern.

In order to achieve the above object, the train control device according to the present invention is the onboard device mounted on the train based on the predetermined information that is always obtained from the ground side. A speed check pattern is generated, train control is performed using the generated speed check pattern, and the generated speed check is performed based on predetermined position information from a ground element installed at a predetermined position on the ground side. In the train control device that corrects the pattern, when the predetermined information is obtained from the ground side at the time of start-up at the start of operation of the train, the track circuit where the own train is located is detected based on the obtained predetermined information Generating means for generating a temporary speed check pattern on the assumption that the head of the own train is located at the approach position of the next track circuit on the train traveling direction side of the detected track circuit, and generating It is characterized by having a control means for train control until the ground coil using a temporary speed Shosa pattern.
In the train control device according to claim 2 of the present invention, when the train enters the next track circuit while traveling using the generated temporary speed check pattern, the head position of the train is the next track circuit. It is characterized in that there is provided a correcting means for correcting the generated temporary speed check pattern on the assumption that the vehicle is in a position where it has traveled a time of two message lengths of predetermined information from the ground side at an allowable speed at the time of entry.

When the train control apparatus according to claim 1 of the present invention obtains predetermined information from the ground side at the time of start-up associated with the start of operation of the train, the track on which the own train is located based on the obtained predetermined information A detecting means for detecting a circuit, a generating means for generating a temporary speed check pattern on the assumption that the head of the own train is located at the approach position of the next track circuit on the train traveling direction side of the detected track circuit, and generating Since the control means for controlling the train to the ground unit using the provisional speed check pattern, a safe speed check pattern can be generated.
In the train control device according to claim 2 of the present invention, when the train enters the next track circuit while traveling using the generated temporary speed check pattern, the head position of the train is the next track circuit. Since the correction means for correcting the generated temporary speed check pattern is provided as the position that has traveled the time of two message lengths of the predetermined information from the ground side at the allowable speed at the time of entry of the vehicle, accurate speed check is provided A pattern can be generated.

  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, and an on-board device B for realizing the train control device of the present invention is mounted on a train A traveling on a rail R. Yes. As shown in FIG. 2 described later, the rail R has a track circuit divided into a predetermined length (in FIG. 2, only three track circuits 1T to 3T are shown for ease of explanation). ).

  In FIG. 1, reference numeral 1 denotes a control signal (corresponding to predetermined information transmitted from the ground side of the present invention) f comprising digital information to one end side (starting end side) of the rail R of one track circuit. It is a ground transmitter. In other words, this ground transmitter 1 is configured in the same manner as a ground device in a well-known ATC, and has predetermined information such as track circuit identification data, route code data, speed limit data, branch data, forward train position or opening section number data. And a control signal f comprising this data group can be supplied to the rail R. The length of this one data group, that is, the time length of the control message is shown here as “t”.

  In FIG. 1, reference numeral 2 denotes a ground element, which is installed at a predetermined position of the track circuit, and can transmit a position signal F including position information indicating the installation position of the ground element 2 toward the vehicle (train). It is configured as follows. The ground element 2 is usually installed near the start side and the end side of one track circuit. In addition, the ground unit 2 has a non-power source type that drives by receiving a power wave from the upper side of the vehicle, or a power source type that has a drive power source, similar to the ground unit used in the well-known ATS-P type. Yes. When the train A passes through the installation position of the ground element 2, the on-board device B of the train element I is configured so that the position signal F is obtained from the ground element 2 and the absolute position of the own train can be detected. Yes.

  The on-board device B mounted on the train A receives information from the ground side via the on-board element (antenna) 10 provided at the lower end of the train A, that is, the control signal f and the ground element from the rail R. 2 has a receiving section 11 for receiving the position signal F from the position 2. In order to simplify the drawing, the vehicle upper element 10 is shown so that the control signal f from the rail R and the position signal F from the ground element 2 can be received by one ground element. Actually, they are provided separately.

  The computing unit 12 of the on-board device B is formed around the CPU, and is configured to control the on-board device B in an integrated manner. That is, the calculation unit 12 is configured to perform predetermined calculation processing using the system program data and the on-board database stored in the memory 13. A speed verification pattern generation unit 14 is connected to the calculation unit 12 so that a predetermined speed verification pattern can be generated under the control of the calculation unit 12.

  In addition to the signal input from the receiving unit 11, the control unit 12 is configured to be able to input a signal from a speed generator (not shown) or the like. Then, the control unit 12 outputs a predetermined output signal such as a brake drive signal obtained based on the generated speed check pattern and the own train speed obtained from the speed generator via the output unit 15. It is comprised so that it can output to the various drive equipments which are mounted in the (not shown).

  The speed check pattern generation control operation will be described below with reference to the explanatory diagram of FIG. In FIG. 2, the track circuit 3 </ b> T is a turn-around section where the last station is located.

  Now, it is assumed that train A is traveling toward track circuit 3T. At this time, the control signal f1 is supplied to the track circuit 3T from a ground transmitter (not shown) to the starting end side of the track circuit 3T. The control signal f1 includes information indicating that the front side of the track circuit 3T (the right side of the track circuit 3T in FIG. 2) is not opened (see FIG. 2A).

  When the train A enters the track circuit 3T, the signal f1 supplied to the rail R is short-circuited by the axle, and the signal f1 is not received by a ground receiver (not shown) provided on the terminal side of the track circuit 3T. It is detected that the train A is present in the circuit 3T (see FIG. 2B). When it is detected that the train A is located on the track circuit 3T, a predetermined control signal f2 for preventing erroneous departure of the train A is sent from a ground transmitter (not shown) to the start end of the rail R of the track circuit 3T. Supplied. While this control signal f2 is received by train i, departure of train i is prohibited (see FIG. 2 (c)).

  After the train A stops at a predetermined position on the track circuit 3T, when a staff member (driver) pulls out a handle from a driver seat (not shown), the power of the train A is turned off. Then, when the handle is put into the driver's seat on the opposite side (track circuit 2T side), the power of train A is turned on.

  Next, when the course in the direction of the track circuit 2T side of the train A is opened (in FIG. 2D, the track circuit 1T is opened), the control signal f2 supplied to the rail R of the track circuit 3T is the control signal. It is switched to f3 (see FIG. 2 (d)). The control signal f3 includes predetermined information indicating that the train A can travel to the track circuit 1T.

  Although train A can detect that its own train is on track circuit 3T by receiving control signal f3, it is in a state where it is not aware of the position of track circuit 3T. Therefore, in the on-board apparatus B of Train A, the temporary speed check pattern P is generated assuming that the head position of the own train is located at the entry position of the track circuit 2T. In generating the speed check pattern P, the speed check pattern in the track circuit 3T is generated so as to have a constant speed of the head check speed V1 that is the maximum allowable speed at the track boundary between the track circuits 3T and 2T ( (See the speed check pattern indicated by the solid line in FIG. 2 (d)). In FIG. 2D, a speed check pattern P indicated by a chain line indicates a case where the speed check pattern P is generated when the current position of the train A is grasped.

  When the train A enters the track circuit 2T as the train A progresses, the control signal f4 supplied to the rail R of the track circuit 2T can be received (see FIG. 2E). When train A receives this control signal f4, it can recognize that the head position of train A is located at the boundary between track circuit 3T and track circuit 2T. The speed check pattern P can be corrected (see correction 1 in FIG. 2E). By the way, the control signal f4 is a control message having a predetermined time length t repeatedly transmitted as shown by the control signal f in FIG. Therefore, in order for train A to obtain the control signal f4, the head position of train A has entered at least at the head hitting check speed V1 for the time length t. For this reason, the above correction is performed on the assumption that the head position of the train A has entered the track circuit 2T for the time t twice as long as the head hitting speed V1 in view of safety.

  When the train a further advances, a position signal F is received from the ground element 2 installed at a predetermined position of the track circuit 2T. When the position signal F is received by the train A, the train A can recognize the absolute position of the own train. Therefore, in the train A, when the position signal F is received, the generated speed check pattern P is corrected (see correction 2 in FIG. 2E).

  As described above, in the train control device configured as described above, the generation of the speed verification pattern of the track circuit section in which the power is turned on is a constant speed verification pattern of the head verification speed of the next track circuit, and the next track When entering the circuit and passing through the ground unit, the generated speed check pattern is corrected. Therefore, a safe and accurate speed verification pattern can be generated.

It is a schematic structure figure of a train control device concerning one embodiment of the present invention. It is explanatory drawing which shows control operation.
