DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door control device of a gate device for controlling passage of a person in a gate passage by opening and closing a door.

[0002]

2. Description of the Related Art As a gate device for controlling passage of a person in a gate passage by opening and closing a door, there is an automatic ticket gate at a station or the like. In the conventional gate device, the starting position of the door before judging the validity of the information possessed by the ticket proving that it has the right to pass through the gate passage is determined by the state in which the door is open and a person can pass (normally open type). in the case of)
Either the door is closed and a person cannot pass through it (in the case of a normally closed type).

[0003]

In the case of the former (normally open type), for example, it is not possible to distinguish between a state before a validity / invalidity determination result is obtained after the insertion of the ticket and a state determined to be valid. . In each case, the door is in the open position. Therefore, the ticket issuer proceeds to the gate passage without being able to confirm the validity / invalidity of the ticket inserted by himself.

[0004] Therefore, when the ticket is accidentally inserted without noticing the shortage of the fare, or when it is determined that the ticket is invalid due to abnormal information on the ticket, the faster the walking speed in the gate passage, the shorter the distance to the door. There was a delay in noticing that the door was closed, and the person could touch the door.

[0005] In the latter case (normally closed type), the door is closed each time a person passes through the gate passage, so that the flow of people trying to pass through the gate is obstructed, and operation becomes difficult especially in congestion. I was

SUMMARY OF THE INVENTION In view of the above, the present invention considers a state before an inserted ticket (including a presented one) is determined, and a state when it is determined to be invalid or valid. The state of the case can be determined by the ticket issuer (including the ticket presenter) from the position of the door, and therefore, based on the determination, the ticket issuer does not touch the closed door when it is determined to be invalid. Or to provide a door control device of a gate device capable of appropriately and quickly performing an action (exiting or passing) after the determination without concern that the door will close when it is determined to be valid. With the goal.

[0007]

To achieve the above object, according to an aspect of, the door control device of the gate apparatus according to the present invention is a gate apparatus for controlling the passage of a person in the gate passage by opening and closing the door, the door is opened a state where the gate passage people can pass through the position while in to half-open state of the gate passage between the state in which the door is a gate passage human not pass closed, the door is to startup position located at all times It is characterized by:

A door driving means, a means for detecting a passing speed of a person near an exit of the gate passage, and a control amount for a return speed of the door from an open position to an intermediate position in accordance with the detected speed; And control means for outputting to the door drive means, wherein the return speed from the open position to the intermediate position is changed according to the speed of a person passing through the gate passage.

Further, means for detecting the passing speed of a person near the exit of the gate passage, means for detecting the approach speed of a person near the entrance of the gate passage, a detected passing speed, an entry speed, and an entry speed detection point. Control means for setting a control amount of a door angle of the starting position of the door and a return speed from the open position of the door to the intermediate position based on a distance from the door to the rotation base of the door, and outputting the control amount to the door driving means. The door angle and the return speed of the starting position of the door are changed according to the flow of people in the gate passage.

[0010]

[Action] when you turned on the ticket, the position of the door, and a state that can pass through a person the gate passage door is opened, the door is closed
Gate passage between the gate passage and the state where no people can pass
It is between a position in which the half-open state. If enabled thrown-in ticket is, the door is open to start from between position within it. When the ticket issuer passes through the gate passage, the door
It is returned between position therein. If ticket is determined to be invalid, it closed from between position therein. When the ticket-on user to exit from the gate passage, the door is returned to between position in the re-beauty.

When a person determined to be valid passes near the exit of the gate passage, passing speed detecting means detects the passing speed. The control means sets a control amount of the return speed of the door from the open position to the intermediate position in accordance with the detected speed, and outputs the control amount to the door drive means. The door driving means returns the door to the intermediate position at the set speed.

Further, the passing speed detecting means detects a speed at which a person determined to be valid passes through the gate passage. The approach speed detecting means detects a speed at which a subsequent person enters the gate passage. The control means is configured to determine the door angle at the door start position and the return speed from the door open position to the intermediate position based on the detected passing speed, the approach speed, and the distance from the approach speed detection point to the rotation base of the door.

[0013]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration related to door control of a gate device to which the present invention is applied.

A ticket information input unit 1 is provided for inputting information recorded on a ticket possessed by a person passing through the gate passage GP to the gate device in order to determine whether the ticket is valid or invalid. This ticket information input unit (hereinafter simply referred to as an input unit) is a reading unit that reads magnetic data when the ticket is a magnetic ticket, and the ticket has an IC having a communication function.
If it is a card, it is a receiving unit.

The data input from the input unit 1 is provided to a judgment unit 2 for judging the validity of the ticket. Judgment unit 2
Is compared with reference data registered in advance by a well-known method in an automatic ticket gate or the like, to determine whether the ticket is valid or invalid, and according to the determination result, a validity determination signal s1 or an invalidity determination signal s2. Is output to the door control unit 3.

Near the entrance of the gate passage GP, there are provided detectors 4a and 4b using a pair of front and rear optical sensors for detecting the progress of a person, and a similar pair of front and rear detectors near the exit of the gate passage GP. 5a and 5b are provided. Detection signals from each pair of detectors 4a, 4b; 5a, 5b are respectively entered into an entrance detecting section 6, an exit detecting section 7, and a passing detecting section 8 for detecting entry, exit, and passage based on an input order or the like.
Given to.

The door D is normally, it is held between a position Dn in which the gate passage between an open position Do and a closed position Dc and half-open state. As shown in FIG. 2, a spring 11 is connected to the door D, and when the spring is in an equilibrium state, the door D
Are connected so as to be held at an intermediate position.

FIG. 3A shows an example in which the door D is provided on both sides of the gate passage GP, and FIG. 3B shows an example in which the door D is provided on one side of the gate passage GP.

When the judging section 2 inputs the validity judging signal s1 to the door control section 3, the door control section 3 gives a forward rotation command signal to the driver 9 based on this, so that the driver 9 rotates the motor 10 forward. Then, the door D is rotated to an open position Do indicated by a two-dot chain line in FIG. 1, and the brake is applied to the motor 10 at the open position to stop. Due to the action of the brake, even if a spring is connected to the door, the door is not returned to the intermediate position. Then, when the passage detection unit 8 outputs the passage detection signal s4 to the door control unit 3 based on the detection outputs of the detectors 5a and 5b, it is determined that the person determined to be valid has passed the gate passage GP. The door control unit 3 drives the driver 9 again to give a reverse rotation command to the motor 10.
The door D returns from the open position Do to the intermediate position Dn.

When the judging section 2 inputs the invalidity judging signal s2 to the door control section 3, the door control section 3 gives a reverse rotation command to the driver 9 based on this, so that the motor 10 is rotated in the reverse direction and the door D Is rotated from the intermediate position Dn to the closed position Dc, and the brake is applied to stop.

Therefore, when entering the gate passage GP, the ticket issuer can notice that the ticket is determined to be invalid by observing the operation of the door. Then, after entering the gate passage, collecting the ticket, and leaving the gate passage, based on the exit detection signal s5 from the exit detection unit 7,
Since the door control unit 3 gives a forward rotation command to the driver 9, the motor 10 is rotated forward and the door D returns to the intermediate position Dn.

As described above, when a person determined to be valid passes through the gate passage, the door is returned to the intermediate position from the open position, but always returns at a constant speed regardless of the passing speed of the passer. In such a case, the follower generally tries to enter the gate passage according to the passing speed of the preceding person, so if the succeeding person is a billless person or the ticket is invalid, the door is opened from the open position Do. It is necessary to rotate all at once to the closing position Dc, and there is a possibility that a successor who has entered quickly may contact the door or a situation may occur in which it is too late to prevent the follower from passing illegally.

Therefore, in a preferred embodiment of the present invention, a passing speed detecting device detects a passing speed of a passing person by using detection signals of a pair of passing detecting detectors 5a and 5b provided near the exit of the gate passage. A unit 12 is provided, and the speed control amount given to the driver 9 of the door control unit 3 is changed according to the speed detected by the passing speed detecting unit. Thus, for example, when the passing speed is high, the driving current given from the driver 9 to the motor 10 is increased, and the door 9 is quickly returned from the open position Do to the intermediate position Dn. In addition, when the passing speed of the preceding person is slow, the speed of returning the door to the intermediate position is reduced, so that the sudden closing motion of the door does not give any discomfort to the following person.

FIG. 4 shows still another embodiment of the present invention. In this example, the addition to approaching speed detecting section 13 of the passing speed detecting section 12 is provided, giving the detection speed door control unit 3, a passing speed V1 of the passage's P _F prior the door control unit 3, Based on the approach speed V2 of the following approacher P _L and the distance L from the approach detection point to the rotation base of the door, when the approacher enters the gate passage at the approach speed,
An appropriate speed V that does not cause discomfort and a door angle θ up to the intermediate position before the determination are calculated, and a control amount is given to the driver 9 based on the calculation result, and the door 9 is rotated from the open position Do to the intermediate position Dn. I try to move it. That is, the door angle θ at the intermediate position and the door closing speed V are determined in accordance with the relative speeds of the front and rear passers-by.

[0025]

As described above, according to the present invention, since the middle position where the gate passage between the open position and the closed position is half-opened is set as the door starting position, the door is turned on. The ticket inserter can immediately distinguish between the state before the determined ticket is determined and the state where the validity determination or the invalidity determination is performed from the operation of the door.
Therefore, when it is determined that the door is invalid, there is no danger of touching the door to be closed. When it is determined that the door is valid, the door can be quickly passed without fear of closing the door.

Further, since the door is waiting at the intermediate position, when a billless person or a ticket holder determined to be invalid attempts to pass through the gate passage illegally, compared with the case where the ticket is closed from the open position, Because you can close the passage faster
The effect of stopping fraudulent persons is improved.

Further, when the inserted ticket is determined to be valid because it is waiting at the intermediate position, the gate passage can be opened more quickly than in the normally closed type. It can be smooth.

Further, since the amount of operation of the door is small, the operation speed of the door to the open position or the close position can be changed according to the walking speed of the person. In the case of, door control that does not cause discomfort to a person trying to pass through the gate passage can be realized.

Further, the passage speed and the entrance speed of the gate passage are detected, and the starting from the door angle and the opening position of the door starting position is performed based on the speed and the distance between the entrance detection point and the rotation base of the door. When the return speed to the position is set, the door can be opened and closed appropriately in accordance with the flow of the person passing through the gate passage, and promptness of the passage control and consideration for the human mind can be rationally realized.
