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 detection device for a vehicle, which detects that the vehicle stops within a fixed position range. In particular, the present invention is suitable for a platform on which a platform door device is installed, which detects that a vehicle stops in a fixed position range.

[0002]

2. Description of the Related Art Conventionally, in order to prevent passengers from falling onto a railroad track and to ensure safety when getting on and off, a platform door device is provided at the front edge of the platform, the opening of which is opened and closed by a home door. It is known that only when the vehicle stops, the home door is opened to open the opening so that the user can get on and off the platform from the entrance / exit of the vehicle through the opening.

When such a platform door device is installed, the vehicle stops in a fixed position range where the vehicle should originally stop, and is opened only when the entrance / exit of the vehicle coincides with the opening of the platform door device. Need to be controlled.

[0004] By the way, in a vehicle equipped with an automatic train operation device (ATO), the vehicle is automatically stopped in a fixed position range by an automatic stop system.
The home door and the vehicle door are opened and closed in conjunction with each other by transmitting and receiving signals between the upper child and the lower child. At this time, if the vehicle is not stopped within the fixed position range, signals cannot be transmitted / received, and both the home door and the vehicle door cannot be opened and closed, thereby maintaining safety.

[0005] On the other hand, in a line that operates a vehicle without many automatic train operation devices (ATO) on a conventional line,
When setting the platform door device on the platform, a plurality of position detection sensors are installed in association with the fixed position range where the vehicle should stop, and the vehicle is determined based on whether the position detection sensor detects the passage of the vehicle. Is stopped at a fixed position.

[0006] Such a device detects whether or not the vehicle has stopped at a fixed position on the ground side.
Position detection sensors are installed at both ends of the fixed position range where the vehicle should stop, the vehicle detection sensors on the approach side (rear side in the vehicle traveling direction) detect the passage of the vehicle, and after a predetermined monitoring time has elapsed, the exit side (vehicle). When the vehicle detection sensor (on the front side in the traveling direction) does not detect the passage of the vehicle, it is general to determine that the train has stopped in the fixed position range. As a technique related to this, there is a technique described in JP-A-6-278599.

[0007]

However, in such a method, it is difficult to set the monitoring time, and if the monitoring time is too short, the vehicle stops even after it is determined that the vehicle has stopped in the home position range. May continue to move and eventually stop past the home position range and not be able to detect it, but if it is longer than necessary, the time the vehicle is parked on the platform This leads to extension, which is not desirable for operation. Therefore, setting the monitoring time to an optimum value is an important issue.

The present invention has been made in view of such a situation, and provides a fixed position stop detection device for a vehicle that can reliably detect in a short time that the vehicle has stopped in a fixed position range.

[0009]

SUMMARY OF THE INVENTION In order to solve such an object, a first aspect of the present invention is a vehicle fixed position stop detecting device for detecting that a vehicle has stopped in a fixed position range. The detection object is provided along the vehicle traveling direction behind the stop position range so that at least one is located in the stop position range corresponding to the fixed position range. A plurality of position detection sensors that detect the passage of the object, and receive signals from the position detection sensor, determine the speed and deceleration immediately before the detection object enters the stop position range, and determine the speed and deceleration. A stop time calculating means for calculating a stop time required for the vehicle to stop after passing through the position detection sensor that has passed just before entering the stop range, After passing the position detection sensor, even if the stop time elapses, if the position detection sensor located at the foremost side in the vehicle traveling direction within the stop range does not detect the passage of the detection target, the vehicle A fixed position stop detecting means for determining that the vehicle has stopped within the fixed position range. Here, “when the passage of the detection target is not detected” means that the position detection sensor does not emit a signal. In this case, the vehicle (detection target) has not moved beyond the position detection sensor that does not emit the signal, and it is determined that the vehicle has stopped in the fixed position range.

According to the first aspect of the present invention, first, when the vehicle enters a fixed position range (for example, a platform), passage of a detection target provided on the vehicle is detected by the position detection sensor. According to the detection result, the stop time calculating means determines the speed and deceleration immediately before the detection target enters the stop position range, and based on the speed and the deceleration, the passing of the position detection sensor immediately before the entry. A stop time required until the rear vehicle stops is calculated. Based on the calculated stop time, the position detection sensor within the stop position range is detected by the fixed position stop detection unit even if the stop time elapses after passing the position detection sensor immediately before entering the stop position range. If no signal is emitted, it is determined that the vehicle has stopped within the fixed position range.

In this way, the fact that the vehicle has stopped in the fixed position range can be reliably detected in a short time.

More specifically, the position detecting sensor is disposed within the stop position range such that a distance from a front end thereof is longer than a length of the inspection object. A front position detection sensor, and an intermediate position disposed rearward of the front position detection sensor in the traveling direction of the vehicle such that a distance from a rear end of the stop position range is longer than a length of the inspection object. A detection sensor, and a rear position detection sensor further disposed on the rear side in the traveling direction of the vehicle than the intermediate position detection sensor, further comprising a signal from the rear and intermediate position detection sensors, First and second time measuring means for measuring the time required for the rear side and the intermediate position detection sensor to pass, and receiving signals from the first and second time measuring means, Intermediate position detection sensor First and second speed detecting means for respectively calculating the passing speed of the vehicle when passing through, and receiving signals from the rear and intermediate position detection sensors, and receiving the signals from the rear and intermediate position detection sensors. A third time measuring means for measuring a time required for the test object to pass between the first and second speed detecting means and a signal from the third time measuring means, Deceleration calculating means for calculating the deceleration of the vehicle when passing between the rear position detecting sensor and the intermediate position detecting sensor, wherein the stop time calculating means comprises the second speed detecting means and the deceleration. Receiving the signal from the detecting means, and calculating the time required for the vehicle to stop after the inspection object has passed through the intermediate position detecting sensor, wherein the fixed position stop detecting means includes the stop time calculating means And before After the signal from the front position detection sensor is received and the detection target passes through the intermediate position detection sensor, and before the stop time elapses, the front position detection sensor detects the passage of the detection target. If not, the vehicle may be configured to determine that the vehicle has stopped within the fixed position range.

According to the second aspect of the present invention, first, when the vehicle enters a fixed position range (for example, a platform), an object to be detected provided on the vehicle is detected by the rear position detection sensor. Thus, it is detected by the intermediate position detection sensor. Then, the first and second time measuring means receive signals from the rear and intermediate position detecting sensors, and both measuring means detect the position before the position where the rear and intermediate position detecting sensors are provided. The time required for the object to pass is measured.

Then, the first and second speed detecting means receive signals from the first and second time measuring means, and based on the passing time measured by the two measuring means and the length of the inspection object. Then, the passing speed of the vehicle (detection target) when passing through the rear and intermediate position detection sensors is calculated.

At the same time, a third time measuring means receives a signal from the rear side and intermediate position detecting sensors, and the third time measuring means intervenes between the rear side position detecting sensor and the intermediate position detecting sensor. Is measured, and deceleration calculating means receives signals from the first and second speed detecting means and the third time measuring means, and decelerates. The calculation means calculates the deceleration of the vehicle between the rear position detection sensor and the intermediate position detection sensor.

[0016] Then, the stop time calculating means is provided with the second
Receiving signals from the speed detection means and the deceleration detection means,
The stop time calculating means calculates a stop time required for the vehicle to stop after the test object passes through the intermediate position detection sensor. Then, the fixed position stop detecting means receives the signals from the stop time calculating means and the front position detecting sensor, and the fixed position stop detecting means passes the stop time after the detection target passes the intermediate position detecting sensor. If there is no signal from the front position detection sensor before elapses, it is determined that the vehicle has stopped within the fixed position range.

According to a third aspect of the present invention, the vehicle stops after receiving the signals from the first speed detecting means, the deceleration calculating means and the stop time calculating means, and passing the intermediate position detecting sensor. Calculate the stopping distance to move up to,
Then, the remaining distance to the front position detection sensor is calculated by using the stopping distance, and a margin time setting means for setting a margin time according to the remaining distance is provided. It is possible to determine whether the vehicle has stopped within the fixed position range based on the time obtained by adding the extra time.

According to the third aspect of the present invention, since the margin time is added to the stop time, the stop time for monitoring whether the vehicle stops in the fixed position range becomes longer, and the stop time passes. A situation in which the vehicle subsequently passes the position where the front position detection sensor is provided is reliably avoided. Also,
The spare time setting means calculates a stop distance at which the vehicle moves after passing through the intermediate position detection sensor until the vehicle stops, obtains a remaining distance to the rear position detection sensor based on the stop distance, and according to the remaining distance. Since the spare time is set, the monitoring time for monitoring the signal (passing of the vehicle) from the position detection sensor does not become unnecessarily long, which is advantageous in detecting a fixed position stop of the vehicle in a short time. is there.

The present invention is effective when the fixed position range in which the vehicle stops is set corresponding to a platform door device for opening and closing a home door.

According to the fourth aspect of the present invention, when the vehicle stops, the vehicle stops quickly and within a fixed position range where the entrance / exit of the vehicle coincides with the opening of the platform door device. It is reliably detected.

As described in claim 5, a plurality of fixed position ranges of the vehicle may be set.

According to the fifth aspect, it is possible to perform different control every time the fixed position range where the vehicle stops is different, and it is possible to realize more detailed control.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory view showing a schematic configuration of a vehicle fixed-position stop detecting apparatus according to the present invention, and FIG. 2 is a block diagram of the same.

As shown in FIG. 1, the platform 1 comprises:
At its front edge, a platform door device 2 is provided,
An opening is provided to correspond to the entrance of the vehicle 3 to be stopped, and the opening is opened and closed by a sliding home door 2a.

Therefore, when the vehicle 3 stops,
It is necessary to stop in a preset fixed position range so that the entrance / exit of the vehicle 3 and the opening of the platform door device 2 coincide with each other. To be detected 1 used to detect
1 (for example, a reflection plate) is provided, and three position detection sensors 12 to 14 for detecting passage of the detection target 11 are provided on the platform 1 side along the traveling direction of the vehicle. That is, the position detection sensors 12 to 14 are provided along the track 4 on which the vehicle 3 travels, and as described later, it is detected that the vehicle 3 has stopped in the home position range, and the door of the vehicle 3 is detected. When it is determined that the opening 3a substantially matches the opening of the platform door device 2, the home door 2a is opened. Note that the head of the vehicle 3 corresponds to the front end of the detection target 11.

A front position detection sensor for detecting the passage of the vehicle 3 within a range where the detection target 11 needs to stop when the vehicle 3 stops at a fixed position range (hereinafter referred to as a stop position range). 12 are provided. Note that the front and rear ends of the stop position range in the traveling direction of the vehicle 3 are P1, P
Indicated by 2.

The distance between the front position detection sensor 12 and the rear end (see point P2) of the stop position range in the vehicle traveling direction is substantially equal to the length W of the detection object 11. I have.

Further, an intermediate position detection sensor 13 for detecting the detection target 11 is provided at a position behind the front position detection sensor 12 in the traveling direction of the vehicle and at a distance L1 therefrom. This intermediate position detection sensor 13
Also, the distance between the stop position range and the rear end in the vehicle traveling direction (see the point P1) is substantially equal to the length W of the detection target 11.

Further, on the rear side in the traveling direction of the vehicle 3 further than the intermediate position detecting sensor 13 and a distance L1
A rear position detection sensor 14 that detects the detection target 11 is disposed at a position that is far away from the intermediate position detection sensor 13 such that the distance from the intermediate position detection sensor 13 is longer than the length W of the inspection target 11. ing.

That is, from the front side in the traveling direction of the vehicle 3, the front, middle and rear position detecting sensors 12, 13, 14 are:
The vehicle 3 is disposed along the traveling path of the vehicle 3 at a distance L1 or L2, so that the traveling state (stop state) of the vehicle 3 can be monitored. Further, the position detection sensors 15, 1
The length W of the detection target 11 is shorter than the installation distances L1 and L2 of 6, 17. Here, the position detection sensors 12 to 14 are such that the detection target 11 of the vehicle 3 is the sensor 1
The output of the signal is continued during the passage before 2 to 14, and the output is stopped when the detection target 11 passes through (see FIG. 3).

The three position detection sensors 12 to 14 are:
The detection of the passage of the detection target 11 (vehicle 3) is performed, and a detection signal is input to the vehicle detection device 15.

The vehicle detection device 15 receives a signal from the rear position detection sensor 14 and measures the time required for the detection target 11 (vehicle 3) to pass in front of the rear position detection sensor 14. A first time measuring means 15A,
A second time measuring unit 15B that receives a signal from the intermediate position detection sensor 13 and measures the time required for the detection target 11 (vehicle 3) to pass when passing the front of the intermediate position detection sensor 13 when passing. And Here, “measure the time required to pass” means that the detection target 11
Has a constant length W, which is the position detection sensor 12-1.
This is because it takes a certain amount of time to pass before and pass through the front of the vehicle.

Further, the vehicle detecting device 15 receives a signal from the first time measuring means 15A and calculates a passing speed of the vehicle 3 when passing through the rear position detecting sensor 14, respectively. Means 15C and a signal from the second time measuring means 15B,
And second speed detecting means 15D for calculating respective passing speeds of the vehicle 3 when passing through the vehicle.

Further, upon receiving signals from the rear and intermediate position detection sensors 14 and 13, it is necessary for the inspection object 11 to pass between the rear position detection sensor 14 and the intermediate position detection sensor 13. A third time measuring means 15E for measuring time, and the first and second speed detecting means 15
C, 15D and deceleration calculating means 15F for receiving signals from the third time measuring means 15E and calculating deceleration of the vehicle 3 between the rear position detecting sensor 14 and the intermediate position detecting sensor 13; The second speed detecting means 15
D and a signal from the deceleration detecting means 15F, and a stop time calculating means 15G for calculating a time required until the vehicle 3 stops after the inspection object 11 passes through the intermediate position detecting sensor 13.

After receiving the signals from the stop time calculating means 15G and the front position detection sensor 12, the detection object 11 passes through the intermediate position detection sensor 13 and the stop time elapses. When there is no signal from the front position detection sensor 12, a fixed position stop detection unit 15H that determines that the vehicle has stopped within the fixed position range (that is, the inspection target 11 is within the stop position range).

The fixed position stop detecting means 15H
Is linked to the home door control device 16, and the home door control device 16 determines whether or not the inspection target 11 has stopped in the stop position range based on a signal from the fixed position stop detection means 15H. The opening and closing of the door 2a is controlled. That is, when the inspection object 11 stops in the stop position range, it is determined that the vehicle 3 has stopped at the fixed position, and the home door 2a is opened.

Here, as the detection target 11 of the vehicle,
Although the reflector provided on the vehicle body is used, the first wheel at the head may be used instead. When the object to be detected is a reflection plate, a reflection detection type beam sensor is used as the position detection sensors 12 to 14, but when a wheel is used instead, the passage of the wheel is performed in a non-contact manner due to a change in speed. Magnetic force sensor (for example, axle detector TAC-7
B, TAC-5B) can be used.

Next, the detection that the vehicle 3 has stopped at a fixed position will be described with reference to FIG.

First, the detection object 11 (length W) moving with the advance of the vehicle 3 is moved to the rear and front position detection sensors 1.
The times t0 and t1 required to pass through the fourth and the fourth 13 are measured by the first and second time measuring means 15A and 15B. At the same time, based on the time when the detection target 11 has completed the passage of the rear and intermediate position detection sensors 14 and 13,
The time T0 required for the detection target 11 to pass between the rear and intermediate position detection sensors 14 and 13 by the third time measuring means 15E (the intermediate position after the passage of the rear position detection sensor 14 is completed). The time until the passage of the detection sensor 13 is completed) is measured.

Then, the first and second speed detecting means 1
5C and 15D use the length W of the detection target 11 and the passing times t0 and t1 to cause the detection target 11 of the vehicle 3 to pass through the rear and front position detection sensors 14 and 13 according to the following equation. Speeds V0 and V1 at this time are obtained.

[0042]

(Equation 1) Then, using the velocities V0 and V1 and the time T0 obtained by the above calculation, the deceleration calculating means 4F determines that the detection target 11 is the rear and front position detection sensors 14, 1 by the following equation.
Calculate the deceleration β when passing through the interval 3.

[0043]

(Equation 2) Then, using the deceleration β, the stop time calculating means 1
In 5G, the stop time S1 from when the detection target 11 completes passing through the intermediate position detection sensor 13 until the speed becomes zero and stops is calculated by the following equation.

[0044]

(Equation 3) During the time until this stop, the detection target 11
Is monitored, and if there is no detection signal from the front position detection sensor 12 during the monitoring, the vehicle 3 does not advance beyond the position of the front position detection sensor 12, so that the vehicle 3 It is determined that the vehicle 3 has stopped.

Here, in order to avoid a situation in which the vehicle 3 passes through the front position detection sensor 12 after passing the monitoring time, the surplus time calculating means 15K is used to determine whether or not the vehicle 3 stops in the home position range. Time margin Δt
Can be calculated and the margin time Δt can be added. The allowance time Δt is equal to the stop distance ST that the vehicle moves after passing through the intermediate position detection sensor 13 until the vehicle stops.
Between the intermediate position detection sensor 13 and the front position detection sensor 12
The remaining distance ΔST = the distance subtracted from the interval L1 between
Since it is considered to be inversely proportional to L1−ST, for example, the stop distance ST and the remaining distance ΔST may be obtained by the following arithmetic expression, and the margin time Δt may be calculated.

[0046]

(Equation 4) In this case, assuming that the coefficient K is 0.1, 0.5 to 0.1 times the stop time S1 is automatically calculated based on the remaining distance, and 0.05 to 0.1 times the stop time S1 depending on the remaining distance. Is automatically calculated and set.

In the above-described embodiment, an example in which the vehicle has one fixed position range is described. However, the present invention is not limited to this case. Can also be applied.

As an example, if the width of the opening of the platform door device is larger than the width of the door of the vehicle, the stop position range is divided into a plurality of ranges according to the width of the door. The present invention can be used in a case where the opening portion of the opening by the home door is changed depending on which range the vehicle stops, and the opening portion of the door of the vehicle and the opening portion by the home door are matched.

For example, when the stop position range is three, that is, a short stop in which the front stops slightly before the fixed position range.
FIGS. 4 to 7 show examples of three zones: a zone, a just zone in which a central stop is a fixed position range, and an over zone in which a rear stop slightly exceeds the fixed position range.
It is explained along. In FIGS. 4 to 7, reference numeral 2b denotes an actuator for opening and closing the home door 2a;
Is a left / right and up / down guide for the home door, and 23 is a left / right guide for the home door 2a.

In this case, the first to fifth position detecting sensors 31 to 35 connected to the vehicle position detecting device 15 'are provided in a straight line along the track. The first, second, and third position detection sensors 31, 32, and 33 correspond to the rear, middle, and front position detection sensors 14, 13, and 12, respectively, and the same applies to the just zone and the over zone. Second,
Third and fourth position detection sensors 32, 33, 34 and third, fourth and fifth position detection sensors 33, 34, 35
Correspond to each other, and about the stop in each zone,
The above-mentioned rear, middle and front position detection sensors 14, 1
It performs the same function as 3 and 12.

Therefore, the five position detection sensors 31 to 31
By detecting the stop position of the detection target 11 by the vehicle detection device 15 ′ based on the signal from 35, it is detected in which zone the vehicle has stopped. It is input to a home door control device 16 that controls opening and closing of the home door 2a.

Then, the left and right home doors 2a are driven and controlled by the home door control device 16, and the left and right home doors 2a are opened (the width when fully open is, for example, L1).
1 = 2600 mm), which is smaller than the width when fully opened at any of the center position, the front position and the rear position, and corresponds to the width of the vehicle door (L13 = 1700).
mm).

Before the vehicle arrives and stops, the opening (width L11 = 2600 mm) of the platform door device is
As shown in FIG. 5, the vehicle is completely closed by the left and right home doors 2a, but the vehicle is detected by the vehicle detection device 15 'based on the signals from the position detection sensors 31-35.
When it is determined that the vehicle has stopped in the zone, the drive of the actuator 2b is controlled by the home door control device 16, and FIG.
As shown in the figure, the left and right home doors 2a are respectively driven left and right from the center position by L13-1 = 850 mm in the opening direction, and the width L13 of the opening at the opening is 1700 m.
m.

When it is determined that the vehicle has stopped in the short zone, the actuator 2b is driven and controlled by the home door control device 16, and the left home door 2a is fully opened (opening width L13-) as shown in FIG. 2 = 1300m
m) and the right home door 2a is L13-3 = 400 mm
And the opening portion is opened at a rear position in the vehicle traveling direction with a width of L13 = 1700 mm.

Further, when it is determined that the vehicle has stopped in the over zone, although not specifically shown in FIG.
Conversely, the right home door 2a is fully opened, the left home door 2a is driven in the opening direction by 400 mm, and the opening portion is opened with a width of 1700 mm at the front position in the vehicle traveling direction.

As described above, the width of the opening of the platform door device is ensured to be large so as to cover a wide stop position range of the vehicle, and the short zone, just
Divided into zones and over zones, regardless of the size of the opening of the platform door device, the opening of the home door is changed according to the zone where the vehicle stopped, so that it matches the opening of the vehicle door In addition, the actual opening width of the home door can be minimized.
Therefore, it becomes possible to shorten the door pocket length. In addition, the stop position range is limited to the minimum required width of the open portion by the left and right home doors regardless of the width of the opening portion, and the center position of the open section is changed according to the vehicle stop position, so that the vehicle stops. The flow of passengers passing through the entrance and the open part is not obstructed.

[0057]

The present invention is embodied as described above, and has the following effects.

According to a first aspect of the present invention, the speed and deceleration of a vehicle (detected object) are detected using a plurality of position detection sensors for detecting the passage of the detected object (vehicle), and the stop time is determined based on the detected speed and deceleration. Since the calculation is performed and the stop of the vehicle is confirmed again by the position detection sensor in the fixed position range, it is possible to reliably detect the stop of the vehicle in the stop position range in a short time.

According to a second aspect of the present invention, a front position detection sensor, an intermediate position detection sensor, and a rear position detection sensor are used as position detection sensors, and signals from these are processed to perform speed, deceleration, and stop. Since the time is calculated, the control is simplified.

According to a third aspect of the present invention, a margin time is added to the stop time to obtain the stop time. If the margin time is added to the stop time, the vehicle stops in the stop position range. It is possible to avoid a situation in which the stop time for monitoring whether or not to pass becomes longer, and the vehicle passes through the position where the front position detection sensor is provided after passing the stop time.
A stop distance until the vehicle stops after passing through the intermediate position detection sensor is calculated, a remaining distance to the front position detection sensor is obtained, and a margin time added to the stop time is increased or decreased according to the remaining distance. Thus, it is possible to detect that the vehicle has stopped in the stop position range in a shorter time and more reliably.

According to a fourth aspect of the present invention, if the stop position range of the vehicle is set in accordance with a platform door device that opens and closes the home door, the opening of the vehicle door becomes the home door opening. The stop of the vehicle can be reliably detected in a short time within the corresponding fixed position range.

If a plurality of fixed position ranges in which the vehicle is to be stopped are set, the stop position of the vehicle can be detected more finely. Therefore,
Even when the opening of the platform door device is wide, the opening of the opening can be changed according to the stop position of the vehicle.
