(First Embodiment)
The outline of the stop position determination device according to the first embodiment is as follows.
The stop position determination device according to the first embodiment is a train based on a bogie detection sensor for detecting at least a part of the bogie of the train, specifically, a bogie wheel, and a detection result from the bogie detection sensor. It is provided with a determination unit for determining whether or not the vehicle has stopped within the target stop range. That is, according to this device, it is determined whether or not the train is stopped in the target stop range based on the stop position of the wheel of the bogie. Since the size (diameter) of the wheels provided on the bogie and the distance between the wheels are designed within a certain dimension range, according to the stop position determination device according to the embodiment, it depends on the vehicle type of the train. Instead, it can be determined whether or not the train has stopped within the target stop range. Hereinafter, the stop position determination device according to the first embodiment will be specifically described.

FIG. 1 is a configuration diagram showing a functional block of the platform system 1 in which the stop position determination device 10 according to the first embodiment is used. FIG. 2 is a plan view showing the platform PF. FIG. 3 is a view of the platform PF viewed from the extending direction of the orbit T.

The platform system 1 includes a motion detection sensor 11, a trolley detection sensor 12, a control device 14, and a plurality of platform door devices 16. The motion detection sensor 11, the trolley detection sensor 12, the stop determination unit 30 (described later) and the stop range determination unit 32 (described later) of the control device 14 constitute the stop position determination device 10.

The plurality of platform door devices 16 are arranged along the track T at the edge of the platform PF. Each of the plurality of platform door devices 16 includes a platform door 20 and a door pocket 22 for accommodating the platform door. The plurality of platform door devices 16 are arranged so that each vehicle door 3a of the vehicle 3 of the train 2 and each platform door 20 face each other when the train 2 stops in a predetermined target stop range. The platform door 20 reciprocates between a position housed in the door pocket 22 and a position pulled out from the door pocket 22 by an opening / closing mechanism (not shown).

The motion detection sensor 11 is a sensor for detecting the presence or absence of motion of the train 2. The motion detection sensor 11 is not particularly limited, but is a distance measuring sensor in the present embodiment, and detects the distance from the motion detection sensor 11 to the leading car of the train 2. The motion detection sensor 11 outputs the detection result to the control device 14.

The dolly detection sensor 12 is installed below the platform PF. The bogie detection sensor 12 can detect at least a part of the bogie 4 when the train 2 stops at or near the target stop range of the platform PF. In the present embodiment, the bogie detection sensor 12 detects the wheels 5 on the platform side of the bogie 4. Possible to be configured. The dolly detection sensor 12 outputs the detection result to the control device 14.

The control device 14 is an electronic control unit including a CPU, ROM, RAM, and the like, and has a function of comprehensively controlling the platform system 1. The control device 14 includes a stop determination unit 30, a stop range determination unit 32, and a processing execution unit 34.

The stop determination unit 30 determines whether or not the train 2 has stopped based on the measurement result obtained from the motion detection sensor 11. Specifically, when the distance from the motion detection sensor 11 to the leading vehicle of the train 2 has changed, the stop determination unit 30 determines that the train 2 is running, and the state in which the change does not occur is a predetermined time. When the above is passed, it is determined that the train 2 is stopped.

When it is determined that the train 2 has stopped, the stop range determination unit 32 executes "stop range determination". In the stop range determination, as will be described in detail later, it is determined whether or not the stopped train 2 is located in the target stop range based on the detection result from the bogie detection sensor 12. In other words, the stop range determination unit 32 determines whether or not the position of the platform door 20 and the position of the vehicle door 3a of the vehicle 3 of the train 2 match.

When it is determined that the train 2 is stopped in the target stop range, the processing execution unit 34 drives the opening / closing mechanism to open the platform door 20. The processing execution unit 34 may notify the station staff, the driver, the conductor, or the like (hereinafter referred to as a person in charge) via the display unit or the like that the train 2 has stopped in the target stop range. Then, when the person in charge of receiving the notification inputs an instruction to open the platform door 20 to the operation panel (not shown), the processing execution unit 34 may drive the opening / closing mechanism to open the platform door 20. Further, when it is determined that the train 2 has not stopped within the target stop range, the processing execution unit 34 notifies the person in charge via the display unit or the like. Further, when the person in charge inputs an instruction to close the platform door 20 to the operation panel, the processing execution unit 34 drives the opening / closing mechanism of the platform door device 16 to close the platform door 20.

FIG. 4 is a diagram for explaining the stop range determination. In the present embodiment, the stop range determination is executed based on the stop position of the bogie 4 (hereinafter, also referred to as the bogie 4t) at the rearmost of the leading vehicle of the train 2. Hereinafter, the range in which the wheels 5 on the platform side of the bogie 4t are assumed to exist when the train 2 is stopped in the target stop range of the platform PF is referred to as "existence range 50". Further, the predetermined range outside the existence range 50 and adjacent to the front side in the train traveling direction of the existence range 50 is the "first adjacent range 51", and the predetermined range adjacent to the rear side in the train traveling direction is the "second adjacent range". It is referred to as "range 52".

In the present embodiment, the dolly detection sensor 12 is an area sensor whose detection range is two-dimensional or three-dimensional. The trolley detection sensor 12 may be, for example, a reflection type laser sensor capable of scanning and irradiating a laser beam. The trolley detection sensor 12 is installed so that the detection range of the trolley detection sensor 12 includes the existence range 50, the first adjacent range 51, and the second adjacent range 52.

When the train 2 is stopped in the target stop range, the wheel 5 of the bogie 4t should be within the existence range 50. Therefore, when the stop range determination unit 32 detects the wheel 5 of the trolley 4t in the existence range 50 and the wheel 5 of the trolley 4t is not detected in the first adjacent range 51 and the second adjacent range 52 by the trolley detection sensor 12. , It is determined that the stopped train 2 is located in the target stop range.

On the other hand, when the detection result by the bogie detection sensor 12 is other than that, that is, when the wheel 5 of the bogie 4t is not detected by the bogie detection sensor 12 in the existence range 50, or the bogie 4t in the existence range 50, the stop range determination unit 32 If the wheel 5 of the bogie 4t is detected even in the adjacent range, the wheel 5 of the bogie 4t is not within the existence range 50, so the stopped train 2 is located in the target stop range. It is determined that it has not been done.

The first adjacent range 51 is a trolley 4 provided in front of the trolley 4t when the wheels 5 of the trolley 4t are within the existence range 50, and the wheels 5 of the trolley 4 adjacent to the trolley 4t are detected. The size should not be set. Further, the second adjacent range 52 is a bogie 4 provided behind the bogie 4t when the wheels 5 of the bogie 4t are within the existence range 50, and the bogie 4 adjacent to the bogie 4t (that is, the second car). The size of the wheel 5 of the front bogie 4) of the vehicle may be set so as not to be detected.

The operation of the platform system 1 configured as described above will be described. When the train 2 enters the platform PF, the stop determination unit 30 determines whether or not the train 2 has stopped based on the measurement result of the motion detection sensor 11. When it is determined that the train 2 has stopped, the stop range determination unit 32 executes the stop range determination based on the detection result from the bogie detection sensor 12. The process execution unit 34 executes the process according to the result of the stop range determination.

As described above, according to the present embodiment, it is determined whether or not the train 2 is stopped in the target stop range based on the stop position of the bogie 4. Therefore, it can be determined whether or not the train 2 is stopped in the stop range regardless of the shape of the vehicle body.

Further, according to the present embodiment, the dolly detection sensor 12 is provided below the platform PF. Therefore, when the train 2 is stopped at the platform PF, the sunlight and the illumination light are shielded by the train 2 and the platform PF, and the sunlight and the illumination light are suppressed from being incident on the trolley detection sensor 12. As a result, it is possible to suppress a decrease in the detection accuracy of the trolley detection sensor 12 due to the environment, and it is possible to accurately determine the stop range.

(Second embodiment)
FIG. 5 is a diagram for explaining the stop range determination by the platform system in which the stop position determination device according to the second embodiment is used. Hereinafter, the differences from the first embodiment will be mainly described.

The platform system of this embodiment includes a plurality of trolley detection sensors 12 in this example. The two trolley detection sensors 12 are area sensors, preferably at the center C of each detection range at the boundary between the existence range 50 and the first adjacent range 51 and the boundary between the existence range 50 and the second adjacent range 52. It is installed so that it is located.

Hereinafter, the range in which the wheels 5 on the front side in the train traveling direction of the bogie 4t are assumed to exist (the range adjacent to the first adjacent range 51) is referred to as the first existing range 50a, and the rear side in the train traveling direction. The range in which the wheel 5 is assumed to exist (the range adjacent to the second adjacent range 52) is referred to as the second existing range 50b.

In the stop range determination unit 32 of the present embodiment, the wheel 5 of the trolley 4t is detected by the trolley detection sensor 12 in the first existing range 50a and the second existing range 50b, and the first adjacent range 51 and the second adjacent range 51 and the second adjacent range 51 are detected. When the wheel 5 of the bogie 4t is not detected in the range 52, it is determined that the stopped train 2 is located in the target stop range.

On the other hand, when the detection result by the trolley detection sensor 12 is other than that, that is, the wheel 5 of the trolley 4t is in at least one of the first existence range 50a and the second existence range 50b by the trolley detection sensor 12. Is not detected, or the wheel 5 of the trolley 4t is detected in the first existing range 50a and the second existing range 50b, but the wheel 5 of the trolley 4t is also detected in the first adjacent range 51 or the second adjacent range 52. If so, it is determined that the stopped train 2 is not located in the target stop range because the wheel 5 of the bogie 4t does not fit in the existence range 50.

According to the present embodiment, the same effect as that of the first embodiment can be obtained. In addition, according to the present embodiment, it is possible to use the range of the center C, which has a relatively high detection accuracy, in the detection range of the trolley detection sensor 12 for the stop range determination, and the reliability of the stop position determination device 10 Can be improved.

(Third embodiment)
FIG. 6 is a diagram for explaining the stop range determination by the platform system in which the stop position determination device according to the third embodiment is used. Hereinafter, the differences from the first embodiment will be mainly described.

The platform system of this embodiment includes a plurality of trolley detection sensors 12. The plurality of carriage detection sensors 12 are line sensors having a line-shaped detection range. The plurality of bogie detection sensors 12 have the optical axis Ax oriented in the horizontal direction substantially orthogonal to the train traveling direction, and the distance between the optical axes Ax is less than the diameter of the wheel 5 of the bogie 4t, for example, at equal intervals. , Arranged along the orbit T.

In the stop range determination unit 32 of the present embodiment, the wheel 5 of the trolley 4t is detected by the trolley detection sensor 12 in which the optical axis Ax passes through the existence range 50, and the optical axis Ax is the first adjacent range 51 or the second adjacent range 51. When the wheel 5 of the bogie 4t is not detected by the bogie detection sensor 12 passing through the range 52, it is determined that the stopped train 2 is located in the target stop range.

On the other hand, when the detection result by the trolley detection sensor 12 is other than that, that is, when the trolley detection sensor 12 in which the optical axis Ax passes through the existence range 50 does not detect the wheel 5 of the trolley 4t, or the light Although the wheel 5 of the trolley 4t is detected by the trolley detection sensor 12 in which the axis Ax passes through the existence range 50, the trolley 4t is also detected by the trolley detection sensor 12 in which the optical axis Ax passes through the first adjacent range 51 or the second adjacent range 52. When the wheel 5 of the bogie 4t is detected, it is determined that the stopped train 2 is not located in the target stop range because the wheel 5 of the bogie 4t does not fit in the existence range 50.

According to the present embodiment, the same effect as that of the first embodiment can be obtained. In addition, according to the present embodiment, since a line sensor that is generally less susceptible to the influence of the environment can be used for the carriage detection sensor 12, the reliability of the stop position determination device 10 can be improved.

(Fourth Embodiment)
FIG. 7 is a diagram for explaining the stop range determination by the platform system in which the stop position determination device according to the fourth embodiment is used. Hereinafter, the differences from the first embodiment will be mainly described.

The platform system of this embodiment includes two trolley detection sensors 12. The bogie detection sensor 12 (also referred to as bogie detection sensor 12_1) installed on the front side in the train traveling direction is configured to be able to detect the wheels 5 of the bogie 4 exiting from the existence range 50, and the bogie installed on the rear side in the train traveling direction. The detection sensor 12 (also referred to as a dolly detection sensor 12_2) is configured to be able to detect the wheel 5 entering the existence range 50. The type of the trolley detection sensor 12 is not particularly limited, and an optical sensor such as an area sensor or a line sensor, a magnetic proximity sensor, or an ultrasonic sensor can be used. In the illustrated example, the two bogie detection sensors 12 are line sensors, and the bogie detection sensor 12_1 is installed so that its optical axis Ax passes through the front end of the train traveling direction in the existence range 50, and the bogie detection sensor 12_1 is installed. Is installed so that its optical axis Ax passes through the rear end of the existence range 50 in the train traveling direction.

The stop range determination unit 32 determines whether or not the train 2 has stopped in the target stop range based on the number of wheels detected by each of the bogie detection sensor 12_1 and the bogie detection sensor 12_2. Specifically, the stop range determination unit 32 subtracts the total number of wheels 5 (N _OUT ) from the total number of wheels 5 (N _IN ) whose entire range has entered the existence range 50. By doing so, the total number (N) of the wheels 5 whose whole is located in the existence range 50 is calculated.
N = N _IN -N _OUT

When the calculated number of wheels N matches the number of wheels of one bogie 4 (2 in the illustrated example), the stop range determination unit 32 determines that the train 2 has stopped in the target stop range and does not match. If this is the case, it is determined that the train 2 has not stopped within the target stop range.

According to the present embodiment, the same effect as that of the first embodiment can be obtained. In addition, according to the present embodiment, a sensor that is generally not easily affected by the environment, such as a line sensor, a magnetic proximity sensor, or an ultrasonic sensor, can be used for the trolley detection sensor 12, so that the stop position can be determined. It is possible to improve the reliability of the device 10.

The configuration and operation of the stop position determination device according to the embodiment have been described above. It is understood by those skilled in the art that these embodiments are exemplary and that various modifications are possible in the combination of each of these components, and that such modifications are also within the scope of the present invention.

(Modification 1)
In the first to third embodiments, a case where the stop range determination is executed based on the detection result of one carriage has been described. In this modification, it is determined whether or not the train 2 is stopped in the target stop range based on the stop positions of two adjacent bogies sandwiching the connecting portion of the vehicles connected to each other.

FIG. 8 is a diagram for explaining the stop range determination by the platform system in which the stop position determination device according to the modified example is used. In this modification, the stop position of the rearmost bogie 4 (hereinafter, also referred to as the first bogie 4a) of the leading vehicle of the train 2 and the front bogie 4 (hereinafter, the second bogie 4b) of the second car. The stop range determination is executed based on the stop position of (also called).

In this modification, the range in which the wheels 5 of the first bogie 4a and the second bogie 4b are assumed to exist when the train 2 is stopped in the target stop range of the platform PF is referred to as an existence range 50. The range in which the wheels 5 of the first carriage 4a are assumed to exist is referred to as the first existence range 50a, and the range in which the wheels 5 of the second carriage 4b are assumed to exist is referred to as the second existence range. It is called 50b.

In this modification, the platform system includes two trolley detection sensors 12. The two trolley detection sensors 12 are area sensors. In the two trolley detection sensors 12, as in the second embodiment, preferably, the center C of each detection range is the boundary between the existence range 50 and the first adjacent range 51, and the existence range 50 and the second adjacent range. It is installed so as to be located on the boundary with 52.

In the stop range determination unit 32 of this modification, the wheel 5 of the trolley 4 is detected in the first existing range 50a and the second existing range 50b by the trolley detection sensor 12, and the first adjacent range 51 and the second adjacent range 51 are detected. If the wheel 5 of the bogie 4 is not detected in 52, it is determined that the train 2 is stopped in the target stop range.

On the other hand, the stop range determination unit 32 does not detect the wheel 5 in at least one of the first existence range 50a and the second existence range 50b when the detection result by the trolley detection sensor 12 is other than that, that is, the trolley detection sensor 12. In this case, or when the wheel 5 is detected in the first existing range 50a and the second existing range 50b, but the wheel 5 is also detected in the first adjacent range 51 or the second adjacent range 52, at least one of the carriages 4 Since the wheel 5 of the wheel 5 is not within the existence range 50, it is determined that the stopped train 2 is not located in the target stop range.

According to this modification, the same effect as that of the above-described embodiment can be obtained.

(Modification 2)
In the embodiment, a case where it is determined whether or not the train 2 has stopped based on the measurement result by the motion detection sensor 11 has been described, but the present invention is not limited to this, and the train 2 is based on the detection result by the bogie detection sensor 12. It may be determined whether or not it has stopped.

FIG. 9 is a diagram for explaining stop determination by a platform system in which a stop position determination device according to another modification is used. For example, the stop determination unit 30 divides the detection range A by the trolley detection sensor 12 into a plurality of division ranges _a0 , and measures the time during which the division range _a0 for detecting the wheels 5 of the trolley 4t is switched, thereby dividing the wheels of the trolley 4t. 5 As a result, the moving speed of the train 2 may be calculated. Then, when the moving speed of the train 2 becomes zero, the stop determination unit 30 may determine that the train 2 has stopped. Alternatively, the stop determination unit 30 may determine that the train 2 has stopped when the moving speed of the train 2 is close to zero, for example, when it becomes (A) or less. Further, for example, the stop determination unit 30 determines that the division range _a0 that detects the wheel 5 of the carriage 4t and the division range _a0 that has not been detected do not change for a predetermined time or more, that is, the detection state in each division range _a0 . If it does not change for a predetermined time or more, it may be determined that the train 2 has stopped.

Further, for example, in the example of FIG. 6, the stop determination unit 30 calculates the moving speed of the wheels 5 of the bogie 4 and thus the train 2 by measuring the switching time of the bogie detection sensor 12 that detects the wheels 5 of the bogie 4. May be good. Then, when the moving speed of the train 2 becomes zero, the stop determination unit 30 may determine that the train 2 has stopped. Further, for example, the stop determination unit 30 determines when the trolley detection sensor 12 that detects the wheel 5 of the trolley 4 and the trolley detection sensor 12 that has not detected the trolley 4 do not change for a predetermined time or more, that is, the detection state by each trolley detection sensor 12. If it does not change for more than an hour, it may be determined that the train 2 has stopped.

In these cases, the motion detection sensor 11 is not required, so that the cost can be reduced.

(Modification 3)
In the embodiment, the case where the stop range is determined based on the stop position of the wheel 5 on the platform side of the trolley 4 has been described, but the wheel 5 (hereinafter, also referred to as the wheel 5a) on the platform side of the trolley 4 and the anti-platform (platform). The stop range may be determined based on the stop positions of both wheels 5 (hereinafter, also referred to as wheels 5b) on the side (far from).

FIG. 10 is a diagram for explaining a stop range determination in a platform in which a stop determination device according to still another modification is used.

In this modification, the platform system includes two trolley detection sensors 12. The two trolley detection sensors 12 are area sensors, in this example distance sensors. The bogie detection sensor 12 on the front side in the train traveling direction has the first presence range 50a of the front wheel 5a on the platform side and its first adjacent range 51, and the first presence of the front wheel 5c on the anti-platform side in the detection range. It is installed so as to include the range 50a and its first adjacent range 51. The bogie detection sensor 12 on the rear side in the train traveling direction has the detection range of the second existence range 50b and the second adjacent range 52 of the rear wheel 5b on the platform side, and the rear wheel 5d on the anti-platform side. It is installed so as to include the second existence range 50b and the second adjacent range 52 thereof.

In the stop range determination unit 32, the wheels 5a, 5b, 5c, 5d are detected in the first existing range 50a and the second existing range 50b by the trolley detection sensor 12, and the first adjacent range 51 and the second adjacent range 52 are detected. If the wheels 5a, 5b, 5c, and 5d are not detected, it is determined that the train 2 is stopped in the target stop range. The stop range determination unit 32 may determine whether the wheel 5 on the platform side or the wheel 5 on the anti-platform side is detected based on the detection distance.

On the other hand, the stop range determination unit 32 does not detect the wheel 5 in at least one of the first existence range 50a and the second existence range 50b when the detection result by the trolley detection sensor 12 is other than that, that is, the trolley detection sensor 12. In this case, or when the wheel 5 is detected in the first existing range 50a and the second existing range 50b, but the wheel 5 is also detected in the first adjacent range 51 or the second adjacent range 52, the wheel 5 is detected in the existing range. Since it does not fit in 50, it is determined that the stopped train 2 is not located in the target stop range.

According to this modification, since the wheels on the anti-platform side are also taken into consideration, the stop range can be determined with higher accuracy.
