Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle stereotaxic layer stop detection system for detecting that a vehicle (including a train) has reliably stopped within a predetermined position within a home track.

Conventionally, the driver or conductor has checked by themselves whether the vehicle has stopped at a predetermined position within the home track.
However, recently, the automation of vehicles has progressed, and vehicles are equipped with automatic driving devices and are now able to operate automatically, and in extreme cases, vehicles are driven by a single person or, in extreme cases, are driven unmanned. There is. ．． It is also conceivable that a platform side door will be installed on the station platform side to ensure the safety of passengers getting on and off the train. It is necessary to be able to stop at a certain position, and it is also necessary to be able to confirm this from within the vehicle. However, in the prior art, it is difficult to check whether the vehicle has stopped within a predetermined position, and a solution to this problem has been desired. The present invention has been made in view of the above, and its purpose is to provide a stereotaxic layer stop detection system for a vehicle that can reliably detect when a vehicle enters a stereotaxic calendar and stops. be. A feature of the present invention is that a vehicle localization layer entry detection device is provided to detect when a vehicle enters a predetermined position on the platform track of a station platform, and the output of this device is received on the vehicle via an information transmission transmitting/receiving device. This and the stop detection output from the vehicle are used to detect that the vehicle has stopped in the correct orientation. Hereinafter, the present invention will be described as
This will be explained in detail using the embodiment shown in FIGS.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, 1 is a station platform, 2 is a vehicle, 3 is a truck on which the vehicle 2 runs, and ACT blockages 3a, 3b, 3c, . . .・
...ATC corresponding to station platform 1
The blockage 3b corresponds to a platform track 3B equivalent to the length of the station platform.

4a, 4b, 4c are IRs installed parallel to track 3.
Each ATC blockage 3a is an information transmission path consisting of a loop.
, 3b, 3c, . . . , and the information transmission path 4b corresponding to the ATC blockage 3b has the same length as or longer than the home track 3B.

5, 6, and 7 are transmitters and receivers corresponding to the information transmission paths 4a, 4b, and 4c, respectively; 8 is a fluid motion device including a vehicle localization layer entry detection device; 9 is a satellite entrainment management system for managing vehicle entrainment; Reference numeral 10 denotes an antenna for receiving ATC signals, information transmission lines 4a, 4b, 4c, and signals from the ground transducer 11 installed at the front of the vehicle 2; The control information necessary for entrainment is transmitted to the corresponding information transmission paths 4a, 4b, 4c, and the answer signal from the vehicle 2 is transmitted to the information transmission paths 4a, 4c.
4b and 4c.

By the way, when the vehicle 2 approaches the station platform 1 and the tail end of the vehicle 2 completely enters the platform track 3B, it is detected by the train detection method (
(track short-circuit type, check-in/check-out type, etc.) is detected by the vehicle localization layer entry detection device of the relay movement device 8, and the device 8 sends an entry completion signal 12 to the transmitter/receiver 6.

As a result, the transceiver 6 transmits a signal of frequency f to the information transmission path 4b. On the other hand, vehicle 2 transmits this signal to antenna 1.
0 to a receiver on the vehicle (not shown). Thereby, the vehicle 2 can confirm that the vehicle 2 has stopped within the home track 3B based on this and the stop detection output from the automatic driving device of the vehicle 2. After confirmation, the system performs operations necessary for automatic operation, such as controlling the opening and closing of train doors. In addition, the information about the stop in the home truck 3B is sent to the antenna 1.
0, if the information is transmitted to the entrainment management system 9 via the information transmission path 4b and the transceiver 6, the entrainment management system 9
Based on this information, it is also possible to establish a fully automated driving system that compares the vehicle entrainment status and outputs commands to open and close the doors of the vehicle 2 and station platform 1 using the reverse flow of information. However, vehicle 2 is definitely home track 3.
In order to detect that the vehicle 2 has stopped within 8 minutes and that the trailing car of vehicle 2 is completely covered with the station platform 1, the AC
It is necessary to align the T-blocking boundary with both ends of the station platform 1, and at the time the vehicle 2 completes entering the platform track 38, a signal of frequency f must be sent to the information transmission path 4b. This makes it possible for the vehicle 2 side to determine that it has stopped in complete one-to-one correspondence with the station platform 1. In addition, in automated systems such as new transportation systems, in order to automate the operation of vehicles, vehicles have functions such as inter-station driving control and station platform stop control, and by combining these functions, A signal from the ground element is used as a trigger signal to generate a stop pattern on the vehicle for stereotaxic layer stop control.

In this case, if the beacon 11 is installed at the input point of the home truck 3B as shown in FIG. If the device receives the information and generates a stop pattern based on the received information, the vehicle 2 can be automatically stopped at a predetermined position while following this stop pattern. If the stereotactic pupil approach signal of the above-mentioned frequency f is received at this stop point, the vehicle 2 will surely move to the home track 3.
This means that it stopped within B. Note that if the vehicle 2 stops straddling the ATC blockages 3a and 3b for some reason, opening and closing the door of the vehicle 2 is extremely dangerous. However, if the condition for opening and closing the door includes the fact that a frequency signal is being received when the vehicle 2 is stopped, sufficient security can be maintained. By the way, when the vehicle 2 stops while the tail vehicle of the vehicle 2 is in front of the home track 3B (inside the ATC blockage 3c), the signal of the frequency f has not been received yet, so in this case, The vehicle can be stopped within the home track 3B by causing it to run again until it receives a signal with frequency f, and then forcibly stopping it by applying a relatively strong brake when the signal with frequency f is received.

That is, an automatic localization layer correction function can also be added. Furthermore, when the home track 3B is overrun for some reason as requested, the conditions under which the ground signal was received from the ground signal 1 and the signal with the frequency f, the vehicle 2 enters the ATC blockage 3a. If the automatic driving device outputs an emergency brake command based on the conditions that are interrupted by the entry, a significant overrun stop can be prevented. Furthermore, while the vehicle 2 is stopped and receiving the signal of frequency f, it is possible to interlock the vehicle 2 so that it does not depart. There is no need to fix the signal to the hr signal, and it is possible to sufficiently ensure safety during vehicle entrainment and departure.

As described above, according to the embodiment of the present invention, the vehicle 2 can be reliably stopped at a position corresponding one-to-one within the platform track 3B of the station platform 1 without adding any special hardware. 2, the opening and closing of the door can be safely controlled locally or from the central entrainment control center.

Furthermore, since the vehicle 2 can receive the localization forgery signal, it can be provided with a stop position correction function that automatically corrects the stop position to a predetermined position when the vehicle 2 stops before the localization layer. Furthermore, when overrunning the home, it is possible to prevent a significant overrun stop. Furthermore, it is possible to prevent the vehicle 2 from accidentally leaving the home truck 3B while it is stopped in the home truck 3B, and there is also the effect that sufficient security can be ensured. Note that FIG. 2 is a block diagram showing another embodiment of the present invention, and the difference between FIG. 2 and FIG. 1 is that in FIG. 1, information transmission paths 4a, 4b, 4c... Although the IR loop is used, in FIG. 2, it is replaced by the information transmission paths 13a, 13b, 13c, etc. of the leaky cape, but the effect is the same even if it is done this way.

In addition, in both Figures 1 and 2, the information transmission line does not have to correspond to ATC blockages on a one-to-one basis, but should be laid in blocks divided into blocks with intervals that fit within the minimum interval for vehicle entrainment. It's okay.

As explained above, according to the present invention, there is a remarkable effect that it is possible to reliably detect that the vehicle has entered and stopped in the correct orientation.
