  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a train control apparatus according to the present invention, and an onboard apparatus B for realizing the train control apparatus of the present invention is mounted on a train A traveling on a rail R. The rail R is formed in a track circuit T divided into a predetermined length. In this embodiment, an example of a train control device that creates a speed check pattern on a vehicle and performs train control using the created speed check pattern is shown as a train control device.

  In FIG. 1, reference numeral 1 denotes a control signal composed of digital information (corresponding to predetermined information transmitted from the ground side of the present invention) to one end side (start end side) of the rail R of one track circuit T. It is a ground transmitter. That is, this ground transmitter 1 is configured in the same way as a well-known ground device in ATC, such as track circuit identification data, route code data, speed limit data, branch data, forward train position information, or open section number data. It consists of a predetermined data group and is configured so that a control signal consisting of this data group can be supplied to the rail R.

  In FIG. 1, reference numeral 2 denotes a ground element, which is installed at a predetermined position of the track circuit T, and can send a position signal 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, as the ground unit 2, there is a non-power source type that receives and drives a power wave from the vehicle upper side, or a power source type that has a drive power source, similar to the ground unit used in the known ATS-P type. doing. And when train i passes the installation position of this ground child 2, the on-board device b of train i obtains a position signal from the ground child 2 and detects the absolute position of the own train (train a). It is configured to be able to.

  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 from the rail R and the on-ground element 2. It has the receiving part 11 which receives the position signal from. In order to simplify the drawing in FIG. 1, the vehicle upper element 10 is shown so that a single vehicle upper element 10 can receive a control signal from the rail R and a position signal from the ground element 2. 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 creation unit 14 is connected to the calculation unit 12 so that a predetermined speed verification pattern can be created under the control of the calculation unit 12. In the memory 13, in addition to the above data, the installation position of the ground element 2 attached along the rail R on which the train A travels, that is, at which point on the rail R the ground element 2 is installed. Predetermined data to be shown is also stored.

  The calculation unit 12 is configured to be able to input a signal from the reception unit 11 and a signal from the speed generator G. And this calculating part 12 is mounted in train i via the output part 15 via the output part 15 predetermined output signals, such as a brake drive signal, based on the produced speed check pattern and the own train speed obtained from the speed generator G. It can be output to various drive devices (not shown). Moreover, the calculating part 12 is comprised so that the present driving | running | working position on the rail R of the own train (train A) based on the information obtained from the speed generator G can be detected.

  Hereinafter, the control operation will be described with reference to the speed verification pattern of FIG. 2 and the flowchart of FIG. In FIG. 2, 1T to 3T are track circuits, and train i is assumed to travel from track circuit 3T to 1T, and track circuit 1T is set at a target stop position a of train i. And Here, two ground elements are provided in each of the track circuits 1T to 3T at a predetermined interval, and reference numerals 2a to 2f are assigned from the track circuits 1T to 3T.

  Now, it is assumed that the train A is traveling on the track circuit 3T toward the target stop position a of the track circuit 1T. During this traveling, the on-board device B of train A generates its own train position information based on the control signal from the ground and the output signal of the speed generator G transmitted from the ground transmitter 1 via the rail R. , And the speed check pattern P is created based on the own train position information corrected by the position information of the position signal obtained when the train A passes through each ground element (2f in FIG. 2) (step 100, Step 102 affirmation, step 104 affirmation, step 106, step 108, or step 100, step 102 negative, step 108. The train A is controlled to operate using the created speed check pattern P until the target stop position a is reached (Yes in S110, S112 or No in S110, S112). That is, the train A is controlled so as to follow the created speed check pattern P and not exceed the speed of the speed check pattern P. If the speed is exceeded, the brake signal is output from the output unit 15. Is output and the train speed is suppressed.

  The above speed check pattern P is created every predetermined time (for example, every few seconds) based on the information obtained from the ground side and the own train position information, and the speed check pattern P created this time is the current speed check pattern. The correction is performed by using the pattern P. And, as described above, when the train A enters the next track circuit and passes through the ground elements 2a to 2f, the absolute position of the own train (train A) is obtained. Information is corrected.

  By the way, when the ground element 2f (train A is running between the ground elements 2f and 2e as shown in FIG. 2) for some reason, the train A is stored in the memory 13. Even if it is detected that the vehicle has passed through the ground element 2f stored therein, the predetermined position information cannot be received from the ground element 2f, that is, idling occurs (No in S104). When the idling occurs, predetermined information (this information is stored in advance in the memory 13) for identifying the ground child 2f that has been idling is recorded (stored) in the memory 13 (S114). ). Therefore, it becomes possible to identify the faulty ground element 2f later based on the contents stored in the memory 13, and to quickly recover from the fault. In addition, when such a ground swing is generated, it can be displayed on the cab.

  Even if the above-mentioned idling occurs, position information is obtained from the ground element 2e when the train A reaches the next ground element 2e, or when the train A enters the next track circuit 2T Since the position can be corrected, there is no problem in train control. However, when the swing is continuously repeated a plurality of times (for example, four times) (Yes in S116), the traveling of train i is performed to ensure safety. An abnormal process for canceling is performed (S118).

  In the above-described example, the train control device is a train control device that uses a speed check pattern. However, other types of train control devices can be used as long as the train control device uses a ground element.

It is a schematic structure figure of a train control device concerning one embodiment of the present invention. It is an example of a speed check pattern. It is a flowchart which shows control operation.
