Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing a collision between a passenger and a vehicle in a passenger transportation service such as a railway.

[0002]

2. Description of the Related Art Conventionally, the technical literature of this type of apparatus is described in "Transportation System, Nikkan Kogyo Shimbun, January 31, 1972.
Published on the day ”.

Conventionally, in a passenger transportation business such as a railway, a collision accident prevention apparatus mainly for a passenger and a vehicle basically detects that a passenger safely gets on and off when the door of the vehicle is completely closed, This is a method in which this is confirmed by, for example, a completion display of a shyness.

[0004] In addition, the boundary of an area that is dangerous when a passenger walks on a platform of a station is indicated by a white line, and when a vehicle approaches or departs, the user is informed, for example, "walk away from the vehicle due to danger and walk inside the white line. Please. "

Originally, it is not possible to confirm whether or not there is a collision accident between a vehicle and a passenger simply by checking the open / closed state of the vehicle door. However, in the conventional example, it was determined that there was no contact accident between the vehicle and the passenger only by confirming that the door of the vehicle was closed at the time of departure.

That is, in the case of a collision accident between a vehicle and a passenger, it is assumed that the door of the vehicle does not close. In the prior art, it is detected that the door is closed, and the fact is displayed. Was confirmed by the driver or conductor to be safe.

In general, the detection that a door of a vehicle is closed is performed by comparing the position with a specified position, and if the difference is within a predetermined allowable error value, it is determined that the door is closed. Was.

However, there is a possibility that the passenger is in contact with the passenger due to a small gap, which may result in, for example, a personal injury.

[0009]

Therefore, the problem in the above-mentioned prior art is that it is not possible to confirm whether or not there is a collision accident between the passenger and the vehicle by merely checking the open / closed state of the vehicle door. I mistakenly judged that it could be confirmed.

That is, the state of the door can be detected and determined only by the state of the door, and the situation relating to a collision accident between the passenger and the vehicle can be determined only under limited conditions. However, I mistakenly thought that they could be directly linked.

[0011] This does not take into account that if no passenger is present (because the passenger is not present), opening and closing the door does not pose a danger to the passenger and has no direct relationship. .

That is, the fact that it is impossible to judge passenger safety unless the presence of the passenger is detected and confirmed is ignored.

[0013]

Therefore, according to the present invention, a detecting device is installed in an area where it is dangerous for a passenger to walk on a platform of a station, and when the vehicle approaches or departs from the area, the passenger walks. Automatically detect the condition, and make an announcement, such as "Be sure to stay away from the vehicle and walk inside the white line for danger." The above-mentioned problem is solved by displaying.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an embodiment of the present invention, wherein 1 detects the presence of a passenger by the presence or absence of pressurization based on the weight of the passenger, and outputs a signal of the detection result. A detection device composed of a group of detection SWs (switches), a personal computer (PC) or the like that receives an output signal from the detection device, processes the signal in accordance with a preset processing condition, and converts the signal into an output signal to a display unit. An arithmetic unit consisting of
Reference numeral 3 denotes a display device for displaying an output signal of the processed content from the arithmetic unit 2.

FIG. 2 shows an electric circuit diagram of the embodiment of the present invention according to FIG. The detection unit 11 is the detection device 1, the power supply unit 12 is the computing device 2, and the display unit 13 is the display device 3.
Are represented on the electric circuit as representatives.

The operation of the embodiment of the present invention will be described below with reference to FIGS.

FIGS. 3A and 3B are diagrams for explaining the principle of operation of the detection device as the central means of the present invention. FIG. 3A is a plan view, FIG. 3B is a sectional view, and FIG. 3C is an electric circuit diagram.

In this example, a detection device 1 for detecting a passenger's weight is installed on a horizontal part (B) and a vertical part (C) outside (A) of a so-called white line of a platform 4 of a station.

It is well known that the horizontal portion (B) is often caught by the door of the vehicle 5 when getting on and off, and the vertical portion (C) often falls into the gap between the platform 4 and the vehicle 5.

For example, there is an announcement at a railway station such as "Please walk inside the white line because of danger." The outside of the white line means a dangerous place where a collision with a vehicle occurs.

FIG. 4 is a diagram showing a case where the presence of a passenger is detected in the vertical portion (C) (detection result ON), and shows an example realized by a known foot switch.

Generally, the weight of a passenger is at least several KG or more, and this weight can be detected by a well-known depression switch.

The well-known foot switch or push switch can be applied to, for example, a weight scale. That is, the weight measurement result is in an ON state when the weight is equal to or more than the set weight, and in an OFF state when the weight measurement result is less than the set weight.

The foot switch of the sewing machine and the pedal of the accelerator or brake of the car can be said to be well-known switches.

That is, the button is turned off without being pressed and turned on when pressed.

FIG. 5 is a diagram showing a case where the presence of a passenger is not detected in the horizontal portion (B) (detection result is OFF), which is an application example realized by a known foot switch.

When the user falls in the vertical direction due to the weight, the push switch provided on the vertical plane is activated by the horizontal component.

As an example of the operation of the push switch, there is a general telephone which can be hung on a wall. The hook switch ON / OFF of this telephone corresponds to the presence or absence of a vertical load.

That is, the operation principle is the same even if the switch is installed horizontally or vertically, but the switch operates similarly even when the load direction is horizontal or vertical.

As shown in FIGS. 3 and 4, a display corresponding to the detected location can be performed.

As described above, the present embodiment has been described by taking as an example the prevention of contact between a passenger and a vehicle. However, the present invention can be applied to an automatic train stop device.

[0032]

As described above, according to the present invention, the detection device installed in the area where it is dangerous for the passenger to walk on the platform of the station allows the passenger to walk there when approaching or leaving the vehicle. For example, every time the automatic detection is automatically performed, an announcement such as “Please walk inside the white line (be away from the vehicle) due to danger” can be reliably executed.

Further, it is possible to reliably determine the safety of the passenger by stopping the determination based on the open / close state of the vehicle door and determining that the passenger is not present in a dangerous place.

Since the presence of a passenger is detected in a place where the presence of a passenger is dangerous, and a display useful for preventing a collision accident is displayed in such a case, for example, a contact between a vehicle and a passenger on a railway platform is made. It can help prevent personal injury due to such factors.
