Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed position stop control device for stopping a train at a target point, and more particularly to an improvement in stop position accuracy.

[0002]

2. Description of the Related Art In recent years, an automatic train operation method (hereinafter referred to as ATO) for automatically controlling operation such as speed control and stop of a train.
Has been adopted. The ATO operation is a method in which the train speed, the position, the operation time, the preceding train and the track condition are always known, and the train speed is controlled while comparing with the reference operation diagram to operate the train and stop at a predetermined position.

As a method for automatically stopping the train at a fixed position, as shown in FIG. 7, a non-powered ground terminal P is set at a fixed position stop control start point and a distance correction point in a fixed position stop control section.
1, P2 and P3 are installed, and when the train 1 receives a signal indicating the start position of the fixed-position stop control from the non-powered ground child P1, the fixed-position stop pattern is used to perform the fixed-position stop control. Each time the signal indicating the distance correction point is received at P3, the remaining distance from the stop target point P is corrected to perform the fixed position stop.

[0004]

As described above, in the conventional fixed position stop control device, the train is stopped at a fixed position by a signal from an unpowered ground terminal installed on the ground. In order to control with high accuracy, it is necessary to arrange many non-powered ground terminals along the track, and there is a disadvantage that the number of devices installed on the ground increases.

In addition, since the fixed position stop control is performed by correcting with the signals indicating the distance correction points transmitted from the non-powered ground terminals P2 and P3, there is no influence of slip or skid between the axle and the rail. The train can be stopped within, for example, ± 350 mm of the stop target point, but it is desired to control the stop position with higher accuracy.

The present invention has been made in response to such a demand, and an object of the present invention is to provide a fixed position stop control device capable of controlling a stop position of a train with a simple configuration and more accurately.

[0007]

In the fixed position stop control device according to the present invention, the ground equipment has a block loop line and an ATC ground device, and the block loop line is provided for each block section. It consists of a parallel two-wire block loop and receives a train detection signal wave from the train and transmits an ATC signal wave to the train. The ATC ground equipment adds an ATC signal and a fixed position stop signal to the ATC signal wave. Is generated and sent to the blocking loop line of the fixed position stop control section, an ATC signal wave in which the stop control signal is added to the ATC signal is generated and sent to the blocking loop line of the home section, and the ATC signal is transmitted to the ATC vehicle. The apparatus performs fixed position stop control of a train when detecting a fixed position stop signal included in the ATC signal wave, and performs train stop control when detecting a stop control signal included in the ATC signal wave. I do.

FIG. 1 is a block diagram showing a configuration of a train operation control device according to one embodiment of the present invention. For example, in a transportation system in an amusement park, a rubber tire vehicle is used, or in a new transportation system in which the vehicle is lightweight and the number of rail short-circuits is small, a track circuit due to an axle short-circuit such as a general railway is used for train detection. Since it cannot be used, as shown in the figure,
Each of the block sections 4T to 7T where the train 1 travels is provided with parallel 2-wire block loop lines 2d to 2g, and the train 1 has a TD transmitter 3 and a TD transmitter 3 as shown in the block diagram of FIG. A
A TC onboard device 4, an ATO control device 5, an onboard antenna 6 provided on the forehead of the train 1, and an onboard antenna 7 provided on the tail of the train 1 are provided. -Check-out method is adopted.
In the check-in / check-out method, a TD transmitter 3 generates a check-in signal and a check-out signal having different frequencies as train detection signals, and transmits the check-in signal from an on-board antenna 6 provided at the front of the train 1 to the ground. To the blocking loop lines 2d to 2g, and a check-out signal from the on-board antenna 7 provided at the rear end of the train 1 to the blocking loop lines 2d to 2g to transmit each of the blocking sections 4T to 7T. To detect the presence or absence of a train.

As shown in FIG. 1, ATC / TD transceivers 9d to 9d are connected to the block loop lines 2d to 2g of each block section 4T to 7T via hybrid transformers 8d to 8g.

0, checkout receiving unit 11, blocking logic unit 12, and A
It has a TC signal selection logic unit 13 and an ATC transmission unit 14.

The check-in receiving section 10 receives a check-in signal transmitted from the train 1. The check-out receiving unit 11 is connected in parallel with the check-in receiving unit 10,
The checkout signal transmitted from the train 1 is received.
The block logic unit 12 detects the train 1 by software logic from the check-in signal received by the check-in receiving unit 10 and the check-out signal received by the check-out receiving unit 11, and controls the route relay TR. That is, the presence of the train 1 is stored under any of the reception conditions of the check-in signal or the check-out signal of the corresponding block section,
Next, even if any of the above conditions are not present, the presence of a train in the forward section is stored, and when a checkout signal for the forward section is received, the existence of the train in the forward section is released only when the checkout signal is received. The ATC signal selection logic unit 13 takes in the forward signal information and the forward train position information, determines a speed limit signal as required, and sends the determined speed limit signal to the ATC transmission unit 14. The ATC transmission unit 14 generates an ATC signal wave having a frequency obtained by adding a fixed position stop signal and a stop control signal to the speed limit signal, and sends the signal to the corresponding loop loop line 2 through the hybrid transformer 8. A generated by the ATC transmission unit 14

The operation of controlling the operation of the train 1 by the train operation control device constructed as described above will be described with reference to the flowchart of FIG. 5 and the change characteristic diagram of the traveling distance and the speed of FIG. explain.

When the departure condition of the train 1 stopped at the home 21 is satisfied, the ATC transmitter 14 generates an ATC signal wave of the ATC 15A or the ATC 15B and generates the block loop line 2.
Send to train 1 via a. The ATO control device 5 of the train 1 performs power running control based on the information included in the ATC signal wave detected by the ATC on-board device 4, and starts the train 1 (step S1). When train 1 is running with departure, ATC
The on-board device 4 automatically controls the speed of the train 1 to be lower than the speed limit based on the received ATC signal. Immediately before the train 1 departs and shifts to the constant speed control, the ATO control device 5 performs the acceleration relaxation control in consideration of the riding comfort (step S2).
Thereafter, constant speed control based on the ATC 15A or ATC 15B sent from the ATC transmitter 14 is performed (Step S).
3). When the train 1 enters the fixed-position stop control section, the ATC on-board device 4 transmits the ATC 15 transmitted from the ATC transmitting unit 14 of the ATC / TD transceiver 9e via the blocking loop line 2e.
The fixed position stop signal included in P1 is determined, fixed position stop control is performed, and the train 1 is decelerated (step S4). In this state, the train 1 enters the blocking section 6T of the home 22,
ATC transmitted from the ATC transmitting unit 14 of the ATC / TD transceiver 9f via the blocking loop line 2f in the C on-board device 4.
When 15P2 is input, a stop control signal included in the ATC 15P2 is determined and stop control of the train 1 is performed (step S5). When the train 1 enters the blocking section 6T of the home 22 and a predetermined time has elapsed, the ATC / TD transceiver 9f A
The TC transmitter 14 transmits the AT signal to the blocking loop line 2f.
The C signal wave is switched to ATC01 to protect the train 1 from erroneous departure (step S6). When switching the traveling direction of the train 1, the ATC transmitter 14 of the ATC / TD transmitter / receiver 9f switches the ATC signal wave to the ATC01 and switches to the ATC01TB after a lapse of a predetermined time (step S7). The ATO control device 5 of the train 1 receives the information of the ATC 01 from the ATC on-board device 4 and determines that the vehicle door opening operation is possible when the train 1 stops. Then, the tour operator performs an opening / closing operation of the vehicle door (step S8). The attendant closes the vehicle door and confirms the safety of the home 22, and then inputs departure permission to start the train 1 (steps S9 and S1).

The ATO control device 5 of the train 1 has an ATC
When the information of ATC01TB is received from the on-board device 4, the route of the train 1 is controlled (steps S7 and S10), and when the train 1 stops, the cab is switched (step S11). When the cab of the train 1 is switched, the TD transmitter 3 of the train 1 switches the on-vehicle antennas 6 and 7 that transmit the check-in signal and the check-out signal. ATC / TD on the ground
The block logic unit 12 of the transmitter confirms the driver's cab change by switching between the check-in signal and the check-out signal sent from the train 1 (step S12).

Thus, the ATC signal added with the fixed position stop signal and the stop control signal is used to block the ATC signal wave.
e, 2f to train 1, so ATC
The train 1 can be accurately stopped at the stop target point P using the fixed position stop signal or the stop control signal included in the signal wave. In addition, by transmitting the ATC signal wave including the switching information of the driver's cab, the traveling direction of the train can be easily switched.
