Abstract

PURPOSE:To prevent passengers from being caught in the doors of a train even if a conductor performs operation of closing the doors while the passengers are getting on or off the train by judging at each door whether or not passengers have already got on or off the train, and sequentially closing the doors from which passengers have got on or off the train. CONSTITUTION:Passenger sensors 3a to 3c for detecting the getting on or off a train of passengers are disposed near the respective doors (a) to (c) of a train. When generated infrared rays are blocked by passengers each of the passenger sensors 3a to 3c detects the getting on or off the train of the passengers. According to door opening/closing operation signals S sent from an operating portion 2 by a conductor each of door opening/closing command output portions 4a to 4c decides whether each operation output (C,O) a to (C,O)c indicates opening or closing of the door. When a door closing operation command O is output and the getting on or off the train of passengers is detected as the door is started to be closed, a door opening operation command C is output at that point to open the door so as to prevent the passengers from being caught in the door.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an automatic door opening/closing device that automatically opens and closes the doors of each car of a train.

(Prior Art) Conventionally, the opening and closing of train doors has been manually performed by the conductor in the crew room of the last car of the train.9 For example, as shown in FIG. Then, the door opening/closing driving section 1 of each vehicle operates via the door opening/closing command output section 4 to open all the doors at once, and when the closing operation is performed, the open doors close at once.

In this traditional method, the conductor would
After passengers have boarded and alighted, all doors on the train must be checked to ensure safety before closing. The conductor directly inspects all the doors of each car on the train. In some cases, such as when the train is curved or the platform is crowded, it may not be possible to see all the doors of the train from the rear of the train where the conductor is. There is a method of sending signals and a TV camera is installed on the platform to show the parts that cannot be seen directly from where the conductor is on the TV monitor.

The conductor sees this and confirms safety.

Even with these safety confirmation methods, conductors may accidentally close the door while passengers are getting on or off the train, and passengers may jump onto the train or leave the train after the door is about to close. When the plane jumped off, five passengers got caught in the door and were injured.

To deal with this kind of interstellar space, on route buses, etc., obstacle sensors are installed near the doors, and safety devices are installed to prevent the doors from closing and people from getting caught in the doors if someone is near the doors. Although it is installed, it is not sufficient as a safety measure when many doors are arranged like trains.

In addition, with the conventional system, if even one of the many doors of each train car is being used for boarding or alighting, all doors must be opened, which has a negative impact on the heating and cooling effect inside the train car. There is also.

(Problem M to be solved by the invention) As mentioned above, the opening and closing of train doors is done manually by the conductor after confirming safety, so if the conductor makes a mistake in judgment, passengers may be unable to get on or off the train. Passengers may be trapped and injured if the door closes. Furthermore, even if the conductor confirms that it is safe and closes the door, passengers may panic and jump on or off the train after the door is about to close.

At this time, passengers may get caught in the door and an accident may occur. In this way, when the train conductor closes the door,
Unlike the doors on local buses, every door on each train car must be done with great care, and the work required is extremely labor-intensive.

The present invention has been made in consideration of the above-mentioned problems, and in addition to the safety mechanism conventionally implemented on the doors of route buses to prevent passengers from getting caught in the door, the present invention also provides a safety mechanism that prevents passengers from getting caught in the door. The purpose of this system is to provide a safe automatic door opening/closing device that makes judgments for each door and closes the door sequentially after passengers have boarded or exited the vehicle, instead of closing all the doors at once.

[Structure of the invention]

(Means and Effects for Solving the Problems) The present invention includes a door opening/closing operation unit that gives an opening/closing command to the entire door of each car of a train from the conductor, a door opening/closing drive unit and a boarding/exiting sensor provided for each door. , which is provided for each door, immediately gives a door opening command to each door opening/closing drive unit in response to a door opening command signal from the conductor, and when there is a door closing command signal from the conductor, it outputs a door opening command to each boarding/exiting sensor. A safe automatic train door opening/closing system equipped with a door opening/closing command output unit that issues a door closing command after confirming that the passenger has finished using an output signal, thereby preventing the door from being closed while passengers are getting on or off the train. It is a device.

(Example) An example of the present invention is shown in FIG. Further, FIG. 2 shows the arrangement of boarding and alighting sensors installed near each door of the train to detect when passengers get on and off the train.

The boarding sensor 3 includes an infrared transmitter 10 and an infrared receiver 11
When the infrared rays emitted from the infrared transmitter IO are blocked by the passenger, it is detected whether the passenger is getting on or off, and a detection signal as shown in FIG. 3 is generated.

The door opening/closing command output unit 4 determines the door opening/closing operation output O1C from the passenger boarding/alighting detection signal E and the conductor's door opening/closing operation signal S as shown in FIG.

That is, when the conductor performs a door opening operation, an opening operation command 0 for all closed doors is output unconditionally.

When the conductor closes a door, he does not immediately output the closing operation command C for all the doors, but closes the doors individually according to the signal from the passenger boarding and alighting sensor installed in each door. Door opening/closing command output unit 4 determines whether or not to perform the operation.
Do it with

For example, if a signal like the one shown in Figure 3 is sent,
When time t□ has passed since no passengers got on or off each door, output a closing operation command C to the door and close the door.
As a result, the doors are closed in order starting from the one where it is determined that five passengers have boarded and alighted.

In addition, it outputs a door closing operation command O, and when it detects that a passenger is getting on or off after the door is about to close, it outputs a door opening operation command C at that point to open the door, thereby allowing one passenger to close the door. Prevent from being pinched.

[Effects of the Invention] As explained above, according to the present invention, even if the conductor accidentally closes the door while passengers are getting on and off, the passenger will not get caught in the door and two passengers will be able to get on and off the train. The door waits for the door to close until the passenger finishes boarding and alighting, and then automatically determines when the passenger has finished boarding and alighting and safely closes the door.

With conventional door opening devices, the conductor closes the door.

All the doors on the train had to be operated with great care, which required a lot of effort. However, if the automatic door opening/closing device of the present invention is used, the conductor will be able to close the doors without much effort. This reduces the burden of work and allows the door to be closed safely.

Furthermore, since the doors are closed sequentially after passengers have boarded and alighted, the effect on the heating and cooling effect of the train can be reduced, which is advantageous in terms of energy conservation.
