[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a train operation control device according to one embodiment of the present invention.
[0007]
The track r on which the train A travels is divided into a predetermined length and formed into a plurality (three in the example shown) of track circuits T1 to T3. Here, it is shown that the train A travels toward the track circuit T1 and that the stop position B is predetermined in the track circuit T1. In the figure, S1 is a traffic light for the track circuit T1, S2 is a traffic light for the track circuit T2, and ground children a1, a2 are respectively provided slightly before the traffic lights S1, S2. These ground children a1 and a2 are configured to transmit predetermined position information to the train A.
[0008]
The on-board device 1 and the wireless device 2 are mounted on the train A. The on-board device 1 is configured around a CPU, creates a predetermined operation pattern P, and controls the operation of the train A along the generated operation pattern P to a predetermined stop position B. It is configured. The on-board unit 1 is connected to an on-board unit 3 provided at the lower part of the head of the train A so that position information obtained from the on-board units a1 and a2 can be obtained via the on-board unit 3. And the speed (traveling distance) information from the speed generator 5 provided on the axle of the train A can be input.
[0009]
The wireless device 2 is configured to be able to wirelessly communicate (communicate) with a ground device 10 provided at a signal handling place via an antenna 4. Then, the wireless device 2 receives the predetermined line segment information of the track r stored in the ground device 10 and outputs the information to the on-board device 1, and outputs the predetermined operation pattern P generated by the on-board device 1. It is configured to be able to transmit predetermined on-board information such as predetermined failure information and the like to the ground apparatus 10.
[0010]
The ground equipment 10 provided at the signal handling office C has an arithmetic unit 11 mainly composed of a CPU. The operation unit 11 is connected to a transmission / reception unit 13 having an antenna 12 so as to be able to communicate with a vehicle (train A). The memory 14 connected to the arithmetic unit 11 stores predetermined line section information such as speed limit information and gradient information of the line r, in addition to program data for performing a check process of the arithmetic unit 11 described later. . The input / output unit 15 connected to the arithmetic unit 11 is formed from well-known input / output devices such as a numeric keypad, a mouse, a display screen, and a printer.
[0011]
Hereinafter, the control operation will be described with reference to the flowchart of FIG. Now, it is assumed that the train A is located on the track circuit T3 in FIG. 1 and is going to travel toward the track circuit T1. Then, it is assumed that the stop position B of the train A is set in the track circuit T1.
[0012]
Since the train A is located within the communication range of the ground device 10, the line information of the track r stored in the memory 14 of the ground device 10 is received by the on-board device 1 via the wireless device 2. (Step 100 affirmative. Hereinafter, the step is referred to as “S”.) Since the train A knows its own train position based on the speed limit information obtained from the speed generator 5, it stops the predetermined position of the track circuit T1 based on the own train position and the line segment information obtained from the ground. A predetermined operation pattern P at position B is created (S102). When creating the on-vehicle driving pattern P, the validity is checked by a safety mechanism provided in the on-board device 1, for example, by a multiplexed arithmetic mechanism. Further, the above-described own train position is corrected to an accurate own train position every time the vehicle passes through the ground children a2 and a1.
[0013]
The information that the train A sets the stop position B of the track circuit T1 as the stop position can be input in advance to the on-board device 1 of the train A, and this information can also be input from the ground, that is, from the ground device 10. The train B can be set by inputting it under the specified information.
[0014]
The driving pattern P created on the vehicle (the on-board device 1) is transmitted to the ground (the ground device 10) via the wireless device 2 (S104). When the ground device 10 receives the operation pattern P from the train A, the ground device 10 uses the train position information (for example, the train position information obtained from the track circuit T3) obtained from the not-shown train position detection device, The validity of the received driving pattern P is determined (S106). In this determination, when the operation pattern is different from the operation pattern assumed in the ground device 10, it is determined that the operation is abnormal, and an emergency stop command is transmitted from the ground device 10 to the on-board device 1 for the train A (S108). denial). Therefore, the train A is emergency stopped to ensure safety. In this case, the traffic lights S1 and S2 for manned operation are also stopped and indicated.
[0015]
When it is determined that the driving pattern P created on the vehicle matches the driving pattern assumed by the ground device 10, that is, when the driving pattern P created on the vehicle is determined to be normal. (Yes at S108), the information indicating that the determination is OK is transmitted from the ground device 10 to the on-board device 1, and the operation is started using the operation pattern P of the train A (S110).
[0016]
While the train A is operating toward the stop position B using the operation pattern P, information on the operation state is sequentially transmitted from the train A to the ground device 10 and monitored by the ground device 10 (S112). In this monitoring, for example, when the operation exceeding the speed limit of the operation pattern P continues for a predetermined time (No at S114), an emergency stop command is transmitted from the ground device 10 to the on-board device 1, and the train A Stopped to ensure safety. Such monitoring by the ground device 10 is continued until the train A stops at the stop position B (S116: Yes).
