It is explanatory drawing explaining operation | movement of.

  1 to 3, a train vehicle 3 traveling on a track 2 laid along a station platform 1 stops at a fixed position on the side of the platform 1. A platform fence device 4 is erected on the track 2 side end floor of the platform 1, and is provided so as to be able to advance and retreat in the vehicle door 3 a and the platform fence device 4 on the platform 1 side of the vehicle 3 when the vehicle 3 stops. The movable door 4a is opened and becomes a passenger passage for train passengers. On the side surface of the track 2 on the track 2 side, five detectors 5 for detecting the stop position of the vehicle 3 are installed at equal intervals in the horizontal direction, and a signal from the detector 5 is sent to the fixed position stop determination device 6. Entered. The installation position of the fixed position stop determination device 6 may be inside the platform fence device 4 or may be another part of the platform 1. As the detector 5, a photoelectric sensor that receives laser light projected from the light emitter and reflected from the side surface of the vehicle 3 is used. The horizontal installation positions of the five detectors 5 are such that when the train stops exactly at the target fixed position, the positions of the five central detectors 5 arranged are the first vehicle 3 and the second vehicle on the train. It is installed so as to be in the center between the vehicle 3 and the vehicle.

  Next, the operation will be described with reference to FIG. In the following description, a case will be described in which the distance between the vehicle 3 at the head of the train and the second vehicle 3 is 500 mm, and the horizontal interval between the five detectors 5 is 375 mm. FIG. 4 shows input signals from five detectors a, b, c, d, e from the front in the traveling direction of the train, error reference values from the target fixed position of the stopped train, and fixed position stop determination device 6. It is explanatory drawing which made the determination result list. Detection by the detector 5 is started when the train travels on the track 2 in a stop system and the leading vehicle 3 passes in front of the installation position of the detector 5. At this time, as shown in case 1 of FIG. 4, all the detectors 5a to 5e are in the ON state because the reflected light from the leading vehicle 3 enters.

  When the train travels within 1000 mm from the target fixed position, as shown in case 2, the detector 5 of e catches the space between the leading vehicle 3 and the second vehicle 3 and turns off. When the train further advances and is within 625 mm from the target fixed position, as shown in case 3, the detector 5 of d is also turned off by catching the space between the leading vehicle 3 and the second vehicle 3. When the train further travels and is within 500 mm from the target fixed position, as shown in case 4, the detector 5 of e is detached from between the vehicles and the reflected light from the second vehicle 3 enters, so detection of e The device 5 is turned on, and only the detector 5 for d catches between the vehicles and is turned off. When the train further advances and is within 250 mm from the target fixed position, as shown in case 5, the detector 5 of c is also turned off by catching between the vehicles. When the train further travels and is within 125 mm from the target fixed position, as shown in case 6, the detector 5 of d is detached from between the vehicles and the reflected light from the second vehicle 3 enters, so detection of d The device 5 is turned ON, and only the detector 5 of c catches between the vehicles and is turned OFF. The state of this case 6 is a state where the train has stopped at the target fixed position accurately. Hereinafter, the case 7 to the case 11 are in a state where the train has overrun, and the individual cases are as shown in FIG.

  The fixed-position stop determination device 6 receives the train stop signal from another device such as a train control device, and the train stop position depends on which of the cases 1 to 11 the input signal from the detector 5 is. Assuming that 625 mm before and after the target fixed position is set as an allowable target stop range, cases 3 to 9 output an IN signal as shown in FIG. For 2, 10 and 11, an OUT signal is output. For example, an operation such as opening the movable door 4a of the home fence device 4 is performed by the IN signal output from the fixed position stop determination device 6.

In the above description, the case where five detectors 5 are installed at equal intervals of 375 mm has been described. However, the number of detectors 5, the installation interval, and the like are not limited to this, and an acceptable target. It can be selected appropriately according to the setting of the stop range, etc., and the purpose is to detect the distance between vehicles. It is desirable to do.
Further, the installation position of the detector 5 only needs to be able to detect the distance between the vehicles when the train stops. For example, the position between the second vehicle 3 and the third vehicle 3 may be detected. It is not limited to between the two vehicles 3 and the second vehicle 3. Furthermore, the detector 5 can be appropriately changed according to building conditions, such as detecting the upper part between vehicles by hanging from the roof of the platform, for example, without being installed on the side surface of the track 2 side of the platform fence device 4 It is.
The detector 5 may be any type of sensor as long as it can detect the distance between vehicles, and is not limited to a photoelectric sensor.
Furthermore, it is conceivable that the detector 5 detects the distance between the second and third vehicles when the train greatly overruns. For such a large overrun state, for example, in FIG. When the case 11 is reached, the signal from the detector 5 is locked, or the stop position is determined not by the fixed position stop determination device 6 but by another device such as a train control device, or the station service The staff should make a decision.

  As described above, since the detector 5 detects a gap between vehicles, it is necessary to perform correction or the like even if the front vehicle has a different front shape or a different vehicle length due to a difference in the model of the vehicle. In addition, since the fixed position stop determination device 6 determines whether the train is stopped within the target stop range where the detector 5 is ON or OFF, complicated calculation, correction, etc. It is a simple configuration that is not necessary.
