Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fixed position stop detection device for detecting that a vehicle stops within a fixed position range. In particular, it is suitable for a platform in which a platform door device is installed, which detects that the vehicle stops in a fixed position range.

[0002]

2. Description of the Related Art Conventionally, in order to prevent passengers from falling onto the 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 can be opened and closed by a platform door. It is known that the platform door is opened to open the opening only when the vehicle is stopped so that the passenger can get on and off the platform through the opening and the exit of the vehicle.

When such a platform door device is installed, the vehicle stops within a fixed position range where it 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.

By the way, in a vehicle equipped with an automatic train operation device (ATO), the automatic stop system automatically stops in a fixed position range.
The platform door and the vehicle door are interlocked to open and close by transmitting and receiving a signal between the car child and the ground child. At this time, if the vehicle is not stopped within the fixed position range, signals cannot be exchanged and neither the home door nor the vehicle door can be opened / closed to maintain safety.

On the other hand, on a line operating a vehicle that does not have many automatic train drivers (ATO) installed on conventional lines,
When the platform door device is set 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 based on whether or not the position detection sensors detect passage of the vehicle. Determines whether or not has stopped at a fixed position.

[0006] Such a device is for detecting 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, and a vehicle detection sensor on the entry side (rear side of the vehicle traveling direction) detects passage of the vehicle, and after a predetermined monitoring time elapses, 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 common 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, even if it is determined that the vehicle has stopped in the fixed position range, May continue to move and eventually stop past the fixed position range and may not be able to detect it, but if it is longer than necessary, it will increase the amount of time the vehicle is stopped on the platform. It leads to extension, which is not preferable for operation. Therefore, setting the monitoring time to an optimum value is an important issue.

The present invention has been made in view of the above circumstances, and provides a vehicle fixed position stop detection device capable of reliably detecting that the vehicle has stopped in the fixed position range in a short time.

[0009]

In order to solve such an object, the invention of claim 1 provides a vehicle fixed position stop detecting device for detecting that the vehicle has stopped within a fixed position range. The detection target is provided, and at least one of them is located in a stop position range corresponding to the fixed position range, and the detection target is provided behind the stop position range along the vehicle travel direction and along the vehicle travel direction. A plurality of position detection sensors that detect passage of an object, and signals from the position detection sensor are received, and the speed and deceleration immediately before the detection target enters the stop position range are obtained. Based on the stop time calculating means for calculating the stop time required for the vehicle to stop after passing the position detection sensor that has passed just before entering the stop range, and the stop time calculating means that has passed just before entering the stop position range. Even if the stop time elapses after passing through the position detection sensor, if the position detection sensor located at the frontmost side in the vehicle traveling direction within the stop range does not detect the passage of the detection target, the vehicle is A fixed position stop detecting means for determining that the vehicle has stopped within the fixed position range is provided. 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 (object to be detected) 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 the fixed position range (for example, the platform), the passage of the detection target provided on the vehicle is detected by the position detection sensor. According to the detection result, the stop time calculating means obtains the speed and deceleration of the object to be detected immediately before entering the stop position range, and the position detection sensor passed immediately before the entrance is passed based on the speed and deceleration. The stop time required until the rear vehicle stops is calculated. Based on the calculated stop time, the fixed position stop detection means detects the position detection sensor within the stop position range even after the stop time has passed after passing through the position detection sensor immediately before entering the stop position range. If no signals are issued, it is determined that the vehicle has stopped within the fixed position range.

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

Specifically, as described in claim 2, the position detection sensor is arranged in the stop position range such that the distance from the front end thereof is equal to the length of the detection object. A front side position detection sensor, and a front side position detection sensor, and a rear side of the front side position detection sensor in the traveling direction of the vehicle such that the distance from the rear end of the stop position range is equal to the length of the detection target. An intermediate position detection sensor and a rear side position detection sensor which is disposed further rearward than the intermediate position detection sensor in the traveling direction of the vehicle, and further receives signals from the rear side and intermediate position detection sensors. First and second time measuring means for measuring the time required for the detection object to pass through the rear side and intermediate position detecting sensors, and a signal from the first and second time measuring means, The rear and middle position detection sensors First and second speed detecting means for respectively calculating a passing speed of the vehicle when passing the vehicle, and signals from the rear and intermediate position detecting sensors to receive the rear position detecting sensor and the intermediate position detecting sensor. Between the above detection target
A third time measuring means for measuring a time required for an object to pass, a signal from the first and second speed detecting means and the third time measuring means, and the rear side position detecting sensor. Deceleration calculating means for calculating the deceleration of the vehicle when passing between the intermediate position detecting sensor and the intermediate position detecting sensor, wherein the stop time calculating means outputs signals from the second speed detecting means and the deceleration detecting means. In front of the intermediate position detection sensor
The fixed position stop detection means receives a signal from the stop time calculation means and the front side position detection sensor, and calculates the time required to stop the vehicle after the detection target passes through. When the front side position detection sensor does not detect the passage of the detection target after the detection target passes through the position detection sensor and before the stop time elapses, the vehicle is within the fixed position range. It can be configured to determine that it has stopped.

According to the second aspect of the present invention, first, when the vehicle enters the fixed position range (for example, the platform), the detection object provided on the vehicle is detected by the rear side position detection sensor, and subsequently, the detection target object is detected. And 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 front of 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 the signals from the first and second time measuring means, and the passing time measured by both measuring means and the detection object.
Passing speed of the vehicle (detection object) as it passes through the rear side and the intermediate position detection sensor based on the length of the object are calculated, respectively.

At the same time, the third time measuring means receives signals from the rear side and intermediate position detecting sensors, and the third time measuring means causes the third time measuring means to connect between the rear side position detecting sensor and the intermediate position detecting sensor. The time required for the object to be detected to pass through is measured, and the deceleration calculating means receives signals from the first and second speed detecting means and the third time measuring means, and decelerates. The deceleration of the vehicle between the rear position detection sensor and the intermediate position detection sensor is calculated by the calculation means.

Then, the stop time calculating means is provided with the second
Receiving signals from the speed detection means and the deceleration detection means of
By the stop time calculation means, the intermediate position detection sensor
A stop time required until the vehicle stops after the detection target has passed is calculated. The fixed position stop detection means receives signals from the stop time calculation means and the front side position detection sensor, and the fixed position stop detection means passes the intermediate position detection sensor through the detection object, and then the stop time. When there is no signal from the front side position detection sensor until the time elapses, it is determined that the vehicle has stopped within the fixed position range.

According to a third aspect of the invention, the vehicle further stops after receiving 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 stop distance to move to
Then, using the stop distance, the remaining distance to the front side position detection sensor is calculated, and a margin time setting means for setting a margin time according to the remaining distance is provided. It is possible to determine whether or not the vehicle has stopped within the fixed position range based on the time obtained by adding the margin time.

According to the third aspect of the 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 long, and the stop time passes. A situation in which the vehicle passes a position where the front position detection sensor is provided later is surely avoided. Also,
The surplus time setting means calculates a stop distance that the vehicle moves until it stops after passing the intermediate position detection sensor, calculates the remaining distance to the rear position detection sensor based on the stop distance, and determines the remaining distance according to the remaining distance. Since the margin time is set by this, the monitoring time for monitoring the signal from the position detection sensor (passage of the vehicle) does not become longer than necessary, which is advantageous for detecting the fixed position stop of the vehicle in a short time. is there.

As described in claim 4, it is effective when the fixed position range in which the vehicle stops is set corresponding to the platform door device for opening and closing the platform door.

According to the fourth aspect of the present invention, when the vehicle is stopped, it is prompt and when the vehicle stops within a fixed position range in which the entrance / exit of the vehicle coincides with the opening of the platform door device. Certainly 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 in which the vehicle is stopped is different, and it is possible to realize finer control.

BEST MODE FOR CARRYING OUT THE INVENTION 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 detection device according to the present invention, and FIG. 2 is a block diagram thereof.

As shown in FIG. 1, the platform 1 is
Platform door device 2 is provided at the front edge of it,
An opening is provided so as to correspond to the entrance / exit of the vehicle 3 to be stopped, and the opening is opened and closed by the slide type home door 2a.

Therefore, when the vehicle 3 stops,
It is necessary to stop within 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. Therefore, the position of the vehicle 3 on the vehicle 3 (vehicle body) side is required. Target 1 used for detecting
1 (for example, a reflector) is provided, and three position detection sensors 12 to 14 that detect passage of the detection target 11 are provided on the platform 1 side along the vehicle traveling direction. That is, the position detection sensors 12 to 14 are provided along the track 4 on which the vehicle 3 travels, and as described below, it is detected that the vehicle 3 has stopped in the fixed position range, and the door of the vehicle 3 is detected. It is determined that the opening 3a and the opening 3a of the platform door device 2 substantially coincide with each other, and the platform door 2a is opened. The head of the vehicle 3 corresponds to the tip of the detection target 11.

Further, a front side position detection sensor for detecting passage of the vehicle 3 within a range in which the detection object 11 needs to stop when the vehicle 3 stops in a fixed position range (hereinafter referred to as a stop position range). 12 are provided. The front and rear ends of the stop position range in the traveling direction of the vehicle 3 are set to P1, P
2 shows.

The front position detection sensor 12 and the front end of the stop position range in the vehicle traveling direction (see point P2) are arranged so that their distance is substantially equal to the length W of the object to be detected 11.

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

Furthermore, the distance L1 is further behind than the intermediate position detection sensor 13 in the traveling direction of the vehicle 3.
A position apart such that said distance between the intermediate position detection sensor 13 is longer than the length W of the detection target 11, the side position detection sensor 14 after detecting the detection target 11 is disposed ing.

That is, from the front side in the traveling direction of the vehicle 3, the front, middle and rear position detection sensors 12, 13, 14 are
They are arranged along the traveling path of the vehicle 3 at a distance of L1 and L0 so that the traveling state (stopped state) of the vehicle 3 can be monitored. Further, the position detection sensors 12-14
The length W of the detection target 11 is shorter than the installation distances L1 and L2. Here, the position detection sensors 12 to 1
4, the detection target 11 of the vehicle 3 is the sensors 12 to 14
The output of the signal is continued during the passage in front of, and the output is stopped when the detection target 11 passes through (see FIG. 3).

The three position detecting sensors 12-14 are
The detection object 11 (vehicle 3) is detected to pass through, and a detection signal is input to the vehicle detection device 15.

The vehicle detection device 15 receives the signal from the rear side position detection sensor 14 and measures the time required for the detection object 11 (vehicle 3) to pass in front of the rear side position detection sensor 14. First time measuring means 15A for
Second time measuring means 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 it passes in front of the intermediate position detection sensor 13. With. Here, “measuring the time required to pass” means 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 through 4 and pass through.

Further, the vehicle detection device 15 receives the signal from the first time measuring means 15A, and calculates the passing speed of the vehicle 3 when passing the rear side position detection sensor 14, respectively. The intermediate position detection sensor 13 receives signals from the means 15C and the second time measuring means 15B.
And second speed detecting means 15D for calculating the passing speed of the vehicle 3 when passing the vehicle.

Further, it is necessary for the detection object 11 to pass between the rear side position detection sensor 14 and the middle position detection sensor 13 by receiving signals from the rear side and middle position detection sensors 14 and 13. 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 the signals from the third time measuring means 15E and calculating the 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 stop time calculation unit 15G that receives a signal from the deceleration detection unit 15F and calculates a time required for the vehicle 3 to stop after the detection target 11 has passed through the intermediate position detection sensor 13.

After receiving the signals from the stop time calculating means 15G and the front side position detection sensor 12, and after the detection object 11 has passed through the intermediate position detection sensor 13, until the stop time elapses, When there is no signal from the front side 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 detection target 11 is within the stop position range) is provided.

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 detection target 11 has stopped within 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 detection target 11 stops within the stop position range, it is determined that the vehicle 3 has stopped at the fixed position, and thus the home door 2a is opened.

Here, as the detection object 11 of the vehicle,
Although the reflector provided on the vehicle body is used, it is also possible to use the first top wheel instead. As the position detection sensors 12 to 14, reflection detection type beam sensors are used when the detection target is a reflection plate, but when wheels are used instead of the detection plates, the wheels do not pass by contact due to changes in magnetic flux. Magnetic force sensor to detect (eg axle detector TAC-7
B, TAC-5B) can be used.

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

First, the detection object 11 (length W) that moves with the progress of the vehicle 3 is the rear side and intermediate position detection sensor 1.
The times t0 and t1 required to pass through 4 and 13 are measured by the first and second time measuring means 15A and 15B. At the same time, with reference to the time when the detection object 11 has completed passing through the rear and intermediate position detection sensors 14 and 13,
The time T0 required for the detection object 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 completion of the passage of the rear position detection sensor 14). 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 passage times t0 and t1 to cause the detection target 11 of the vehicle 3 to pass through the rear side and intermediate position detection sensors 14 and 13 according to the following equation. The speeds V0 and V1 at the time are calculated.

[0042]

[Equation 1] Then, using the velocities V0, V1 and the time T0 obtained by the above calculation, the deceleration calculation means 4F causes the detection target 11 to detect the rear side and intermediate position detection sensors 14, 1 by the following equation.
The deceleration β when passing between 3 is calculated.

[0043]

[Equation 2] Then, using the deceleration β, the stop time calculation means 1
The 5G calculates the stop time S1 from the completion of the passage of the intermediate position detection sensor 13 to the stop when the speed becomes zero due to the following expression.

[0044]

[Equation 3] Then, during the time until this stop, the detection target 11
Behavior is monitored, and if there is no detection signal from the front side position detection sensor 12 during the monitoring, the vehicle 3 is not proceeding beyond the position of the front side position detection sensor 12, so within the fixed position range. It is determined that the vehicle 3 is stopped.

Here, with respect to the monitoring time of whether or not the vehicle 3 stops in the fixed position range, in order to avoid a situation in which the vehicle 3 passes through the front position detection sensor 12 after the monitoring time has passed, the margin time calculating means 15K. Depending on the margin time Δt
Calculates the, by also be made to add the margin time Δt
Wear. For example , the stop distance ST and the remaining distance ΔST are calculated by
Alternatively, the margin time Δt may be calculated.

[0046]

[Equation 4] In this case, if the coefficient K = 0.1, 0.5 to 0.1 times the stop time S1 is automatically calculated according to the remaining distance, and the setting is performed.
Is determined.

In the above embodiment, an example in which the vehicle has one fixed position range has been described. However, the present invention is not limited to this, and there is a plurality of vehicle fixed position ranges. Can also be applied to.

As an example, when the width of the opening of the platform door device is larger than the width of the vehicle door, the stop position range is divided into a plurality of ranges according to the width of the door, It can be used when the opening portion of the opening by the platform door is changed depending on in which range the vehicle is stopped so that the opening portion of the vehicle and the opening by the platform door coincide with each other.

For example, in the case of three stop position ranges, that is, a short stop which causes a front stop just before the fixed position range.
4 to 7 show examples in the case of three zones: a zone, a just zone that is a central stop that is a fixed position range, and an over zone that is a rear stop that slightly exceeds the fixed position range.
Follow along. In FIGS. 4 to 7, 2b is an actuator for opening and closing the platform door 2a, and 22b.
Is a horizontal and vertical guide of the platform door, and 23 is a horizontal guide of the platform 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 on a straight line along the track, and the short zone is carried out as described above. The first, second and third position detection sensors 31, 32 and 33 correspond to the rear side, middle and front side position detection sensors 14, 13 and 12 of the above-mentioned embodiment, 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, about the stop in each zone,
The rear side, middle and front side position detection sensors 14 and 1 described above.
It has the same function as 3,12.

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

Then, the left and right platform doors 2a are drive-controlled by the platform door control device 16, and the open portion by the left and right platform doors 2a (the width when fully opened 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 which 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 left and right platform doors 2a are fully closed, but the vehicle detection device 15 'detects the vehicle just by the signals from the position detection sensors 31 to 35.
When it is determined that the vehicle has stopped in the zone, the home door control device 16 drives and controls the actuator 2b, and
As shown in, the left and right platform doors 2a are driven in the opening direction from the center position to the left and right by L13-1 = 850 mm, and the width L13 of the opening portion at the opening is 1700 m.
It is opened to m.

When it is determined that the vehicle has stopped in the short zone, the home door control device 16 drives and controls the actuator 2b, and as shown in FIG. 7, the left home door 2a is fully opened (opening width L13- 2 = 1300m
m) and the right platform door 2a is L13-3 = 400 mm
Driven in the opening direction only, 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.
On the contrary, the right home door 2a is fully opened, the left home door 2a is driven by 400 mm in the opening direction, and the opening portion is opened at a front position in the vehicle traveling direction with a width of 1700 mm.

In this way, the width of the opening of the platform door device is ensured to be large so as to cover the wide stop position range of the vehicle, and the short zone, just
It is divided into a zone and an over zone, and regardless of the size of the opening of the platform door device, the opening part by the platform door is changed according to the zone where the vehicle is stopped so that it matches the opening by the vehicle door. The actual opening width of the platform door can be minimized.
Therefore, the door pocket length can be shortened. In addition, the stop position range is limited to the minimum necessary opening width of the open part by the left and right platform doors regardless of the width of the opening part, and the center position of this open section is changed according to the vehicle stop position. There is no obstruction to the flow of passengers passing through the entrance / exit and the opening.

[0057]

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

According to the invention of claim 1, the speed and deceleration of the vehicle (detection target) are detected by using a plurality of position detection sensors for detecting the passage of the detection target (vehicle), and the stop time is calculated based on the detected speeds and decelerations. Since the calculation is performed and the stop of the vehicle is confirmed again by the position detection sensor within the fixed position range, it is possible to reliably detect that the vehicle has stopped within the stop position range in a short time.

As described in claim 2, a front side position detection sensor, an intermediate position detection sensor and a rear side position detection sensor are used as the position detection sensors, and signals from them are processed to process the speed, deceleration and stop. Since the time is calculated, the control becomes easy.

As described in claim 3, if the allowance time is added to the stop time to obtain the stop time, the allowance time is added to the stop time to stop the vehicle in the stop position range. It is possible to avoid a situation in which the stop time for monitoring whether or not the time is longer becomes longer and the vehicle passes a position where the front position detection sensor is provided after the stop time has passed.
The stop distance until the vehicle stops after passing the intermediate position detection sensor is calculated, the remaining distance to the front position detection sensor is calculated, and the margin time added to the stop time is increased or decreased according to the remaining distance. If so, it is possible to detect that the vehicle has stopped within 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 corresponding to the platform door device for opening and closing the platform door, the opening of the vehicle door becomes the platform door opening. It is possible to reliably detect that the vehicle has stopped in the corresponding fixed position range in a short time.

By setting a plurality of fixed position ranges in which the vehicle should stop, it is possible to detect the stop position of the vehicle more finely. Therefore,
Even if the opening of the platform door device is wide, the opening portion of the opening can be changed in the vehicle according to the stop position.
