Description

  The present invention relates to a vehicle door pinching detection device, and in particular, accurately detects that a passenger or a passenger's clothes and belongings are pinched by a side door when a railway vehicle that has been handled as a passenger at a station departs. And it is related with the door pinching detection apparatus of a railway vehicle which can cancel | release a door pinching state.

  Conventionally, when a railway vehicle that has been treated as a passenger at a station departs, passengers or passenger clothing and belongings may be sandwiched between side doors, and the following safety devices are disclosed. Proposed.

  FIG. 7 is a schematic view of a conventional safety device for an automatic door of a railway vehicle.

  In this figure, 101 is a double-open automatic door, and 102 is a rotating rubber roller disposed at the tip of the double-open automatic door 101.

Here, we propose a human body motion sensor that uses a mechanical door pinching and detaching mechanism and a mechanical actuator. In other words, a freely rotatable rotating rubber roller 102 using a rubber roller is disposed at the open / close joint tip of the double door automatic door 101, and a rotation detection sensor is attached to the rotating rubber roller 102, so that an object is placed between the doors. When it was caught and tried to be taken out, it was detected by the rotation detection sensor, and the door could be opened and closed again. Also, the object sandwiched between the doors can be removed relatively easily by the rotation of the roller.

  The mode of the railcar door pinching will be described in detail below.

  (1) As shown in FIG. 8, at the station, the hem 103 of the clothes of the passenger 105 on the platform of the railway vehicle 100, that is, on the platform of the station (such as an umbrella or a portable item) seems to be sandwiched between the side doors 104. In this case, the clothes can be pulled out by pulling the hem 103 of the clothes from the outside of the railway vehicle.

  (2) Also, as shown in FIG. 9, when something like a handbag 201 is sandwiched between the side doors 104 at the station, it cannot be pulled out even if pulled strongly from the outside of the railway vehicle 100. However, if the hand holding the handbag 201 is released, the handbag 201 remains in the car and remains unsatisfactory, but does not spill over to a personal accident.

  (3) However, as shown in FIG. 10, in the case where the object 301 is inflated by entering the hem 103 of the passenger 105, the pocket of the clothing, or the like, it can be pulled out even if it is pulled strongly from the outside of the railway vehicle. It is difficult to remove clothes from the passenger 105's body instantly. As a result, the passenger 105 is dragged with the departure of the railway vehicle 100 while being sandwiched between the side doors 104, which may cause a serious accident.

  In such a case, the rotating rubber roller 102 cannot be rotated by the automatic door with the rotating rubber roller shown in FIG. This is because if the object in the pocket hits the rotating rubber roller 102, the rotating rubber roller 102 cannot be rotated from there, and as a result, it is not detected by the rotation detection sensor, and the door can be opened and closed again. Because it was not possible, there was a problem that it was not possible to prevent serious matters leading to personal injury.

  Further, in the method shown in FIG. 7, even when the passenger pulls out the hem of the clothes, the rotating rubber roller rotates so that it detects it and opens the side door. There is a concern that delays will increase.

  Also, when the door is pinched in the vehicle, contrary to FIG. 10, the vehicle is in a running state with an object outside the vehicle, but it is not dragged by people, so there is a problem as shown in FIG. 10. There is no. However, for example, if an object that remains outside the vehicle by the time the passenger reaches the target station cannot be pulled into the vehicle, if the platform of the disembarking station is the opposite door, the passenger The problem arises that can not get off.

  In view of the above situation, the present invention provides a vehicle door pinching detection device that can reliably detect only a situation where it cannot be escaped from a side door, or can support escape from a door pinching state. The purpose is to do.

That is, it is a host control device having a display device, a sound device, and a circuit including passing control in a train. A is a door command signal transmitted from the host control device 17 to the lower control device, B is a door pinching detection signal (emergency signal) transmitted from the lower control device 11 to the host control device 17, and C is a lower control device. 11 is a door pinching detection signal (warning signal) transmitted from the host controller 17 to the host controller 17, D is a speed signal of the railway vehicle transmitted from the host controller 17 to the host controller 11, and E is a door opening / closing device from the host controller 17 16 is a door opening / closing signal transmitted to 16. The driven gear 5 and the drive gear 6 can be housed in the upper part of the side door 1 of the railway vehicle.

  FIG. 2 is an operation flowchart of the door pinching detection device showing the embodiment of the present invention.

  First, as the first stage of the flow, the following initialization is performed when the vehicle battery is turned on. That is, the door F (door command “open” detection), emergency F (passenger drag detection on the platform), and warning F (detection of passengers in the vehicle) are turned off. In the following flow, the speed V1 <V2 (for example, V1 is 5 km / h, V2 is 15 km / h), and the contact of the speed detection relay is used. Further, this flowchart does not describe processing for canceling instantaneous transient states and noise data.

  First, it is checked whether or not the railcar door command is in the “closed” state (step S1). When the door is “open” (NO), the door F is turned on (step S2), the emergency F is turned off (step S3), and the warning F is turned off (step S4). If the door is closed (YES) in step S1, it is checked whether or not the door F is ON (step S5), and if YES (when the door that has been opened once is closed after the customer is handled) Is input (step S6). As a result, it is checked whether or not the traveling speed of the vehicle is slower than V1 (step S7). As a result, when the speed is lower than V1 (for example, the speed is 0 to 5 km) (YES), the derived rotation command for the door pinching detection rotating body is turned ON (step S8). Next, the rotation sensor is input (step S9). Next, it is checked whether or not the rotation speed of the rotation sensor is slower than the set speed (step S10). As a result, when the rotation speed of the rotation sensor is slower than the set speed, that is, when the rotation sensor decelerates or stops (door pinching detection state), the emergency F is turned on (step S11). That is, it is possible to detect the drag of the passenger on the home.

  In step S7, in the case of NO (for example, a speed of 5 km or more), it is checked whether the vehicle traveling speed is slower than V2 (for example, 15 km / h) (step S12), and the speed is slower than V2 (for example, , 5 to 15 km / h) (YES), the introduction rotation command for the door pinching detection rotating body is turned ON (step S13), and the rotation sensor is input (step S14). Next, it is checked whether or not the rotation speed of the rotation sensor is lower than the set speed (step S15). As a result, when the rotation speed of the rotation sensor is slower than the set speed, that is, when the rotation sensor decelerates or stops (door pinched state), the warning F is turned on (step S16). That is, it is possible to detect a passenger's door pinching in the vehicle.

  In step S12, in the case of NO, that is, when the traveling speed of the vehicle is faster than V2 (for example, 15 km or more), the derived rotation command for the door pinching detection rotating body is turned OFF, and the door pinching detection rotating body is introduced. The train is driven with the rotation command OFF and the door F OFF (for example, the derivation and introduction rotation is stopped at 15 km or more) (recognized that the current door handling has ended normally).

  With this configuration, it is possible to save labor without driving the door pinching detection rotating body during a time period when it is not necessary.

  FIG. 3 is a diagram showing a rotation mode of the door-clamping detection rotating body when the railway vehicle according to the present invention is stopped.

  As shown in this figure, in a state where the railway vehicle is stopped, the door pinching detection rotating body 2 is rotated in a direction in which the object pinched between the door pinching detection rotating bodies 2 is led out of the vehicle. That is, the left door pinching detection rotating body 2 rotates in the clockwise direction, and the right door pinching detection rotating body 2 rotates in the counterclockwise direction.

  Therefore, when a passenger's clothes and belongings outside the vehicle are sandwiched between the left and right door-slip detection rotating bodies 2, the sandwiched article has a function of deriving the sandwiched outside. In addition, as shown in FIG. 4, when an object 20 or the like inside the passenger's pocket outside the vehicle is sandwiched between the left and right door pinching detection rotating bodies 2 or the like, It becomes difficult to rotate the door pinching detection rotating body 2, and the rotation of the left and right door pinching detection rotating bodies 2 decelerates. Eventually it will stop. Since it can be determined that this state is a very dangerous state for passengers outside the vehicle (the passengers are pinched by the passengers outside the vehicle), the rotation sensor 10 promptly decelerates (or stops) the left and right door pin detection rotor 2. To detect. That is, the voltage by the rotation / voltage converter 12 and the voltage by the current / voltage converter 13 corresponding to the rotation command value of the motor 7 are compared by the comparator 14, and the critical door pinching detection signal A is converted to the lower control device. When the crew member turns off the power, operates the brake, stops the vehicle immediately, and performs the in-vehicle broadcast or the like and operates the crew switch 9 by the notification from the control unit 15 through the host control device 17, the host control device The door opening / closing command B is issued from 17 and the door opening / closing device 16 is operated to open the door, thereby eliminating the door pinching state of passengers outside the vehicle leading to a serious accident.

  As described above, according to the present invention, it is possible to reliably avoid a situation that may have a serious accident.

  FIG. 5 is a diagram illustrating a state in which the door pinching detection device for a railway vehicle according to the present invention operates in a traveling state up to a certain speed of the vehicle.

  When the vehicle is running, if the passengers in the vehicle are in the door-to-door state, if the vehicle leaves the station and is within a predetermined time (until the predetermined speed is reached), the vehicle is caught between the door-closing detection rotors. The door-clamping detection rotator was rotated in the direction to introduce the stuff into the car. That is, as shown in FIG. 5, only the left and right door pinching detection rotating bodies 2 can be driven so as to introduce the one sandwiched between the left and right door pinching detection rotating bodies 2 into the vehicle interior side. That is, the left door pinching detection rotating body 2 rotates counterclockwise, and the right door pinching detection rotating body 2 rotates clockwise. In addition, when the door pinching is detected by driving the door pinching detection rotating body 2 itself, the crew member does not stop the train and does not open the side door (the crew member is pinched outside the door). Only to recognize).

  FIG. 6 is a schematic diagram of a transmission mechanism for a drive pin on the side of a door motor and a drive gear on the side of a drive motor, showing another embodiment of the present invention.

  In this figure, 21 is a door pinching detection rotating body mounted at the tip of the side door of the railway vehicle, 22 is a motor side driving gear, 23 is the door pinching detection rotating body 21 and a motor side driving gear 22. The belt 23 is provided with a concavo-convex gear 24 on the inner peripheral surface thereof. In addition, this mechanism can be accommodated in the door pocket of the upper part of the side door of a railway vehicle.

  According to the present invention, the crew member who has received the notification of the pinch information (emergency F) performs the door operation after powering off, braking, and stopping. As vehicle equipment, (1) notification to the cab (sound, pilot off), (2) power running cut (automatic / manual), emergency brake (automatic / manual), (3) the side door of the relevant railway vehicle It is also possible to perform opening / closing control.

  In the above embodiment, a cylindrical rotating body is shown as the door pinching detection rotating body. However, a plurality of spherical rotating bodies arranged in a skewer shape or a plurality of cylindrical rotating bodies are arranged. And various modifications are possible. The material of the rotating body is preferably safe even if a person is caught and has a large friction coefficient.

  Furthermore, the method of driving the door pinching detection rotating body has shown a configuration via a power transmission circuit such as a gear from a rotation driving device. However, the door pinning detection rotating body is supplied with electric power to detect the door pinching detection. The configuration may be such that the rotator itself is directly driven, and the power source may be other than the motor.

  Further, the detection of the rotation state of the door pinching detection rotating body may be performed by a magnetic, optical, or mechanical detection method in addition to an electrical detection method. Further, the comparison unit may compare the rotational speed in addition to the voltage comparison, or may compare a certain value with the rotational speed sensor output without using the current / voltage on the driving side.

  It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made based on the spirit of the invention, for example, using a door closing interlock check result instead of a door command. It is not excluded from the scope of the invention.
