DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic ticket gate and, more particularly, to an automatic ticket gate with improved ability to prevent a ticketless person from passing through a ticket gate passage, and improved safety when a user collides with a door.

[0002]

2. Description of the Related Art Conventionally, in an automatic ticket gate, a ticket such as a ticket or a commuter pass is inserted into a main body of the automatic ticket gate (hereinafter referred to as a main body), and data is recorded on the ticket. If the result of the calculation processing is a condition that allows a ticket gate, the door provided in the main body is opened (if the main body is a normally open type, the door is opened), and the user can pass through the ticket gate passage. ing.

[0003] Further, when a result of an arithmetic processing based on data recorded on the inserted tickets cannot permit a ticket gate, or when a person without a ticket is detected, the door is closed and the user is closed. Is configured to be blocked from passing through the ticket gate passage.

[0004] Furthermore, in a non-contact type automatic ticket gate that has been proposed in recent years, that is, an automatic ticket gate that transmits and receives data between a main body and tickets in a non-contact manner, a ticketless person is detected. When the door is closed, the door is closed (for example, JP-A-1-246687).

[0005] In the present invention, not only a user who has an invalid ticket and the calculation result of the ticket does not permit a ticket gate, but also has an effective ticket. A user who cannot permit a ticket gate because of an unsatisfactory calculation process on tickets is also treated as a ticketless person.

When a bidder is detected, the door is closed as described above. However, when the bidder collides with the door, the door is closed to protect the bidder from the collision. The door is opened by a friction clutch or the like when a force greater than a predetermined value acts on the door without bringing the door into a completely locked state (for example, Japanese Patent Laid-Open Publication No. No. 54-55400).

[0007]

However, in the above-mentioned conventional automatic ticket gate, the door is closed when a billless person is detected, and when a user (no billee) collides strongly in this closed state. Although the door is configured so as to be pushed and opened, there is a problem that it is difficult to adjust how much impact force acts on the door to be pushed and opened.

[0008] For example, if the door is adjusted to be opened with a small collision force, the user is protected from a collision, but there is a disadvantage that a billless person is easily passed. Further, if the door is adjusted so as to be opened with a large collision force, the performance of blocking the passing of a billless person is enhanced, but the possibility that the billless person collides with the door and the unexpected situation is increased.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an automatic ticket gate that has a high ability to prevent untagged persons from passing and that is excellent in safety in the event of a collision with a door.

[0010]

Automatic ticket gate according to the present invention, in order to solve the problems] In order to achieve the above object, when detecting a no-bidders, so as to close the wicket passage this side as a rotation axis,
In an automatic ticket gate having a door rotated by a motor via a friction clutch, a position detecting means for detecting a position of the ticketless person in a ticket passage, and a speed detecting means for detecting a speed of the ticketless person in a ticket passage. Means, a door rotation angle detecting means for detecting a rotation angle of the door when the door is pushed and opened by a billless person, and a rotation speed of the door when the door is pushed and opened by a billless person. Door rotational speed detecting means, frictional force controlling means for controlling the frictional force of the friction clutch, motor rotational force controlling means for controlling the rotational force of the motor, and when the door is pushed open by a billless person. Door re-closing control means for moving the door by rotating the motor in the reverse direction up to the rotation angle of the door at the original closed position; the position detection means; the speed detection means; and the rotation angle detection means For each input of each detection value detected by the door rotation speed detection means, the most appropriate value is obtained from a fuzzy rule containing data of an appropriate friction force of the friction clutch and an appropriate rotation force of the motor of the door reclosing control means. Outputs reasonable frictional and rotational forces , and the billless person touches the door
It is characterized by having the a fuzzy controller for controlling the pre-Symbol frictional force control means and said door reclosure control means so as not to risk their free bidder when.

[0011]

In the above construction, the friction clutch control means and the door re-closing control means determine the speed of the billless person, the position of the billless person, the rotation angle of the door, and the rotation angle when the door is pushed and opened by the billless person. With the frictional force (slip torque) of the friction clutch and the rotational force (torque) of the motor derived by fuzzy inference, the door closing strength and the re-closing strength are dangerous to the unnamed person.
To control so as not to give the insurance.

A pair of plural main bodies 1, 1 are arranged side by side at a predetermined interval, and the interval between the main bodies 1, 1 is formed in a ticket gate passage P. Then, when a billless person is detected, the door D to which the billless person (user) A advances is placed as shown in FIG.
1 to a predetermined closing position (hereinafter, referred to as a status closed position) indicated by a two-dot chain line in FIG. 1 to close the ticket gate passage P. It is configured as follows.

For example, when a user A inserts a ticket (not shown) into the insertion slot 2 of the main body 1 on the right side and enters the ticket gate passage P to enter, the user A The position and the moving speed of the user A are detected by a plurality of human detectors S, S... Provided between the main bodies 1 and 1, and a calculation result based on the inserted tickets can permit participation. In the case of conditions, doors D, D of both bodies 1, 1
Is opened to the status open position (when both the main bodies 1 and 1 are of the normally open type), and is closed to the status closed position if the user is determined to be a billless person.

The turning mechanism of the door D will be described with reference to FIGS. The rotation mechanism of the doors D, D of the main bodies 1, 1 is the same except that the doors D, D are symmetrical.
D is configured to be rotated synchronously by a controller provided in one main body 1 described later.

Hereinafter, the turning mechanism of the door D located on the left side of FIG. 1 will be described with reference to FIG. The end of the door D on the front side in the traveling direction of the ticket gate P is rotatably supported by the main body 1 by the shaft 3 and extends on the opposite side to the door D and opposite to the ticket gate P. Four.

The base 4 is connected to the end of an arm 5 which is rotated by a reversible motor M having a speed reducer and a connecting rod 6.
Are connected via The arm 5 includes bevel gears 6a, 6
b, is fixed to the upper end of the drive shaft 7 rotated by the motor M, and the drive shaft 7 is divided at an intermediate portion, and an electromagnetic friction clutch 8

FIG. 3 is a right side view of FIG. 2. The friction clutch 8 is composed of a spline 8a provided at the lower end of the upper drive shaft 7a and a ferromagnetic material engaged with the spline 8a. It comprises a spline bearing portion 8b and an electromagnet portion 8c provided above the bevel gear 6b at the upper end of the lower drive shaft 7b. Therefore, by changing the amount of current supplied to the coil 8a of the electromagnet section 8c,
c can adjust the force for attracting the spline bearing portion 8b, and adjust the friction force (slip torque) of the friction clutch 8.

In FIG. 3, S is a sensor not shown in FIG. 2, and optically detects the position of an opening (not shown) provided in a disk 9 provided on the upper drive shaft 7a. The rotation angle of the upper drive shaft 7a, that is, the rotation angle of the door D is configured to be detected, and the rotation speed of the door D is detected from the rotation angle with respect to a predetermined time. It is configured.

In FIG. 2, C is a controller for controlling the main body 1 in an integrated manner, and its electrical configuration is shown in FIG.
That is, the controller C is a central processing unit (C) that performs arithmetic processing using a system program stored in the ROM 10 and working data stored in the RAM 11.

Note that the CPU 12 includes many devices such as a magnetic head for reading data recorded on the tickets inserted into the main body 1 or writing new data on the tickets. Although connected, they are omitted because they are not directly related to the description of the present invention.

In FIG. 5, a door D indicated by a solid line is a status closed position, and indicates a door position when the user A is detected as a billless person, and the traveling direction of the ticket gate passage P (see the arrow in FIG. 5). (Hereinafter, the angle is based on this line) θ ₁ is 31 °.

The door D shown by a chain line in FIG. 5 is a door rotating position when pushed and opened by a billless person, and its angle θ ₂ is 51 °. The door rotation angle θ ₂ is the maximum angle that can prevent the passing of a billless person.

An example of a billless person pushing and opening the door D is when a user A having a valid ticket is determined to be an invalid ticket due to a calculation error or the like, and the user naturally passes the ticket. It's time you think you can. Even in such a case, most of the users, the door D is to be pushed open to an angle theta _2, retracts know that it has been blocked passage.

Therefore, in the automatic ticket gate according to the present embodiment, the angle θ ₃ (= 20 °) of the door rotation width from the door rotation angle θ ₂ to θ _{1 is} defined as the shock absorbing area A (the ruled line in FIG. 5). The rotation of the door D is controlled in accordance with the fuzzy inference described in detail below. When the shock absorbing area A is represented by the distance in the direction of passage of the ticket gate passage P, the distance from the reference line to the tip of the door D indicated by the chain line is L ₁ (250 mm), and is indicated by the solid line (status When the distance to the tip of the closed position) the door D and L ₂ (165mm), the buffer distance L ₃ is represented by (L ₁ -L _2), the actual distance is about 85mm
Becomes

The following (1) to (4) are antecedents of the membership function in fuzzy inference, and (5)
Is then the Department. (1) X: Membership function indicating the degree of distance between the user (no bills) and door (status closed position) D Z: Door position PS: Position quite close to door PM: Position slightly close to door PB: A position slightly far from the door (2) V: Membership function indicating the degree of the moving speed of the user NB: Away from the door fairly quickly NS: Away from the door Z: Stopped state PS: A slow approach to the door Yes PB: Approaching the door fairly quickly (3) θ: Membership function indicating the degree of door angle Z: Maximum door angle for shock absorption PS: Angle slightly in the shock absorption area PM: Significantly in the shock absorption area Angle PB: Closed position (4) DV: Membership function indicating the degree of door speed in the shock absorbing area A NB: Moving very quickly in the opening direction NS: Moving in the opening direction Z: Stopping state PS: Moving slowly in the closing direction PB: Moving very quickly in the closing direction (5) MC: Membership function indicating the degree of braking output Z: Very weak braking force ( PS: slightly strong braking force (strong torque of motor M) PB: fairly strong braking force (strong friction force of friction clutch)

The above membership function is shown in FIG.
(5) are shown as membership function diagrams. FIG. 7 shows a setting example of the fuzzy rule table 20. The description of each column of this fuzzy rule table is described below. 1. If X is PB, V is PS, θ is PS and DV is PB, MC is Z if the user slowly enters the main body and is a little far from the door,
If the door is in the closed position, the braking output is reduced. 2. If X is PS, V is Z, θ is PB and DV is Z,
When the PB door is in the closed position and the user stops very close to the door, the MC does not risk the user from receiving an impact on the door. . 3. If X is Z, V is PS, θ is PM and DV is NS, MC will prevent the PB user from slowly moving the door slowly at the door position, since there is no danger even if the braking force is suddenly increased. Emphasizes power and outputs fairly strong braking power. 4. If X is Z, V is Z, θ is PM and DV is PS,
The MC tries to open the door that the PS user is trying to close, but if the door is moving slowly in the closing direction, the MC moves the door to the closed position with slightly stronger braking force. 5. If X is PS, V is NS, θ is PB, and DV is Z, MC places a great deal of braking force on the PB door when the door is in the closed position and the user starts slowly moving away from the door. Output. 6. If X is PB, V is PB, θ is Z and DV is PB, the MC enters the automatic ticket gate fairly quickly, and if the door is operating in the closing direction, Because it is dangerous to collide, it outputs a fairly weak braking force. 7. If X is Z, V is PB, θ is PM and DV is NB, MC is Z. If the user approaching the door fairly quickly,
If the door is moved very quickly in the opening direction, it is dangerous to suddenly increase the braking force, so that a relatively weak braking force is output. 8. If X is Z, V is PS, θ is Z and DV is NS,
When the PB user advances slowly and strongly pushes the door to reach the maximum door angle for shock absorption, there is no danger even if the braking force is suddenly increased. Output. 9. If X is Z, V is Z, θ is Z and DV is Z, MC
When the user slowly moves forward and pushes the door strongly to open the door and reaches the maximum shock absorption door angle, if the user and the door are in a stopped state, consider that the door will be moved to the closed position and consider a little stronger braking Output. 10. If X is PM, V is NB, θ is PM, and DV is PB, MC is PS. The PS user is a little closer to the door, but there is no danger of collision if he is away from the door very quickly. Outputs a slightly stronger braking force.

An example of control using the above fuzzy rules will be described below. (Rule 1) Fuzzy rule when no force is applied to the door from the outside If X is PB, V is PS, θ is PS and DV is PB,
The MC weakens the braking force when the Z-user slowly enters the automatic ticket gate and is slightly far from the door if the door is in the closed position. (Rule 2) Fuzzy rule when door is pushed open X is Z, V is PS, θ is PM and DV is NS, M
C outputs a fairly strong braking force when the PB user moves the door a little slowly at the door position, because there is no danger even if the braking force is suddenly increased. X is Z, V is PB and DV is NB
Then MC is Z. This is because if a user approaching the door very quickly moves the door in the opening direction very quickly at the door position, it is dangerous to suddenly increase the braking force, so that a very weak braking force is output. As described above, as the danger increases, the braking force is gradually increased, and control is performed to effectively use the shock absorbing force area and to ensure safety. (Rule 3) Fuzzy rule when pushing back the door If X is Z, V is PS, θ is Z and DV is NS, MC
When the PB user slowly and powerfully pushes the door open and reaches the maximum door angle for shock absorption, there is no danger even if the braking force is suddenly increased, so the emphasis is on stopping power and a fairly strong braking force is output. . If X is Z, V is Z and DV is Z, MC is PS.
When the user and the door are stopped, a slightly stronger braking force is used in consideration of operating the door to the closed position. in this case,
Move to the closed position gradually and slowly while completely blocking the user.

[0029]

Automatic ticket gate according to the present invention is, by fuzzy inference, the rotational force of the motor and the frictional force of the friction clutch
Because so Gosuru control so as not to risk to non-bidders, Musatsu person without giving the required more of an impact on the non-bidders also in contact with the door, blocking the passage of non-bidder It is possible to return the door pushed and opened by the billless person to the original closed position without danger to the billless person.
