Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an automatic ticket gate installed and used on routes where passengers with magnetic tickets and passengers with non-magnetic tickets coexist.

[Conventional technology and its drawbacks]

A conventional automatic ticket gate includes a ticket transport section (not shown) and a reading section provided within the ticket transport section, as well as a determination section 1, a reversible counter 2, a passage detector 3, and a gate circuit, as shown in FIG. 4, a no-ticket detector 5, and an entry detector 6.

Then, when a magnetic ticket of a predetermined ticket type is inserted into the ticket slot of the automatic ticket gate, the ticket transport section transports the magnetic ticket,
A reading section reads information D for automatic ticket gates recorded on the ticket and inputs it to a determining section 1. The determining unit 1 determines whether the information is valid or invalid using a normal method, and when it is determined to be valid, it outputs a signal _s1 , which is given to the reversible counter 2 as an addition signal. The reversible counter 2 adds "1" each time an addition signal is input. In addition, reversible counter 2
, a detection signal s ₂ output by the passage detector 3 to detect when a person passes through the ticket gate passage.
is given as a subtraction signal, and "1" is subtracted each time this subtraction signal is input.

The reversible counter 2 outputs a credit signal s ₃ to the gate circuit 4 when the content is "1" or more, and outputs a zero signal s ₄ to the no-bill detector 5 when the content is "0".

A detection signal s5 from an entry detector 6 for detecting that a person has entered the ticket gate passageway is input to the gate circuit 4 and the no-ticket detector ₅ , respectively.

In this way, when the just-inserted ticket is determined to be valid, the content of the reversible counter 2 becomes "1" by the validity determination signal s ₁ (addition signal) from the determination section 1, and the credit signal s ₃ is sent to the gate circuit 4. Therefore, when the person inserting the ticket enters the ticket gate passage and the entry detector 6 outputs the detection signal _s5 , the gate circuit 4 satisfies the logic condition and the ticket gate passage of this ticket gate is output. Outputs passage permission condition signal S ₀ .

This passage permission condition signal causes the door to be kept open if the automatic ticket gate is of a normally open type, and drives the door open if it is of a normally closed type.

Then, when the customer passes through the ticket gate, the reversible counter 2 subtracts "1" from the detection signal _s2 of the passage detector 3, so if the ticket inserted by another customer has not been determined to be valid during that time, , the content of the reversible counter becomes "0" and a zero signal _s4 is output to the no-tag detector 5.

Therefore, when a customer whose ticket is subsequently determined to be invalid or a customer who does not insert a ticket attempts to pass through the ticket gate passage, the entry detector 6 outputs the detection signal _s5 , and the no-ticket detector is activated. 5 satisfies the logical condition and outputs the no tag detector _s6 . This no-ticket detection signal is used as the passage prevention condition signal Sc for ticket gate aisles, and in normally open type ticket gates it drives the door to close the aisle, and in normally closed type ticket gates it drives the door to close the aisle. maintain the condition.

Furthermore, based on the no-ticket detection signal _s6 , a display (not shown) indicates that the returned ticket should be received and retreated from the ticket gate passageway, and an alarm is sounded.

On the other hand, if a non-magnetic ticket is inserted into the ticket slot, the determination unit 1 determines that it is invalid and does not output the validity determination signal _s1 , so that the holder of the non-magnetic ticket enters the ticket gate passage. In this case, the no-tag detector 5 is activated and the person is prevented from passing through the passage.

On routes that have partially introduced automatic ticket gates, or on routes that have automatic ticket gates that can be boarded from routes that do not have automatic ticket gates, there will be a mix of magnetic ticket holders and non-magnetic ticket holders. As mentioned above, in conventional automatic ticket gates, non-magnetic tickets cannot pass through the ticket gate passage.

For this reason, conventionally, in order to allow non-magnetic ticket holders to pass through the ticket gate, one of the following methods has been adopted. One method is to pass through a manned ticket gate that is always open. According to this method, station staff will also be required at the ticket gates, and the staff reduction effect of introducing automatic ticket gates will not be achieved.

Another method is to have a ticket issuing machine exchange a non-magnetic ticket for a magnetic ticket that can be used at an automatic ticket gate, and then insert the magnetic ticket into the automatic ticket gate and allow it to pass through. However, this method requires equipment to read the printed information on the non-magnetic ticket and magnetically record it on the magnetic ticket, which has the disadvantage of increasing equipment and operating costs.

[Technical problem to be solved]

This device allows not only magnetic ticket holders but also non-magnetic ticket holders to pass through automatic ticket gates under certain conditions, and prevents unauthorized passage by invalid ticket holders or non-magnetic ticket holders. The aim is to provide an automatic ticket gate that can

[Means to solve the problem]

The automatic ticket gate according to this invention adds "1" each time a validity determination signal is input from the determination section that determines whether the ticket gate information recorded on the inserted ticket is valid or invalid, and a reversible counter that subtracts “1” each time a detection signal is input;
a first gate circuit that outputs a passage permission condition signal when the output when the content of the reversible counter is “1” or more and the detection signal of the entry detector are input;
In an automatic ticket gate having an output when the content of the reversible counter is "0" and a no-tag detector that outputs a no-touch detection signal as a passage blocking condition signal when a detection signal from the entry detector is input. , In order to solve the above problems, there is an open switch that is operated by a station staff and clears the reversible counter at the time of startup, and when the output signal of the open switch and the approach detection signal are input under the condition that no bills are detected. a second gate circuit that outputs an addition signal to the reversible counter; and a third gate circuit that outputs an addition signal to the reversible counter when the output signal of the open switch and the no-bill detection signal are input. It is characterized by

[Effect]

Upon declaration from a customer with a valid non-magnetic ticket,
When the station staff turns on the release switch, the output signal of the release switch is input to the second gate circuit and the third gate circuit.

Furthermore, the reversible counter is cleared by the rising edge signal of the open switch ON, and its contents become "0". Therefore, the reversible counter outputs a zero signal to the no tag detector.

When the release switch is ON, if the no-ticket detector is not operating, that is, if the customer has not entered the ticket gate passageway of the automatic ticket gate, the second entry detection signal will be activated when the customer enters the ticket gate passageway. Since it is input to the gate circuit, it is output after satisfying the logic conditions.
As a result, the reversible counter is set to "1" and outputs a credit signal to the first gate circuit. Therefore, since the first gate circuit satisfies the logic condition by the credit signal and the entry detection signal, the first gate circuit outputs the passage permission condition signal.

In addition, if the customer has already entered the ticket gate passage when the open switch is turned on, the no-ticket detector is activated and the input is input to the third gate circuit, so the third gate satisfies the logic condition and is reversible. Output to counter.
Therefore, similarly, the content of the reversible counter becomes "1" and a credit signal is output, so the first gate circuit satisfies the logic condition and outputs a passage permission condition signal, allowing the customer to enter the automatic ticket gate. You can pass through the ticket gate.

When passing through the ticket gate passage, the reversible counter subtracts "1" from the output of the passage detector, and its content becomes "0".

The station staff confirms that the passenger with a non-magnetic ticket has passed through the ticket gate and turns the release switch OFF again.
For the next customer, a normal determination process for the magnetic ticket is performed. That is, when a valid magnetic ticket is inserted, the first gate circuit outputs a passage permission condition signal based on the output of the reversible counter and the detection signal from the entry detector. However, if the inserted magnetic ticket is invalid or if the person enters the ticket gate without a ticket, the ticket-free detector operates based on the output of the reversible counter and the detection signal from the entry detector. Output a signal.

[Example of implementation of this idea]

Next, an embodiment of this invention will be explained based on FIGS. 1 and 2.

As shown in FIG. 1, this invention includes a determining section 1, a reversible counter 2, a passage detector 3, a first gate circuit 4, and a no-ticket detector, which are similar to the components of the conventional automatic ticket gate shown in FIG. 5 and the entrance detector 6, an open switch 7, a second gate circuit 8, and a third gate circuit 9 are added to realize the purpose of this invention. Its additional configuration is simple.

The release switch 7 is installed, for example, on a monitoring board in a control room, and is operated by a station staff member based on a notification from a passenger who has a valid non-magnetic ticket in order to allow the passenger to pass through the ticket gate passageway of the relevant ticket gate. It is.

When the open switch 7 is turned on, its rising signal is input to the reversible counter 2 in order to clear it. In addition, the output when the open switch is ON is s ₇
is given to the first gate circuit 8 and the second gate circuit 9 as one drive input. The second gate circuit 8 is also configured to receive the detection signal _s6 from the no-bill detector 5 as a control input, and to receive the detection signal from the entry detector 6 as another drive input. Further, the second gate circuit 9 is configured so that the detection signal _s6 of the no-bill detector 5 is applied as another drive input.

Next, the effects of the above configuration will be explained.

The operation when a predetermined magnetic ticket is inserted into the ticket slot of the automatic ticket gate is the same as that of the conventional machine described above, so the explanation will be omitted to avoid redundant explanation.

Next, if you insert a non-magnetic ticket into the ticket slot,
Since the determination unit 1 determines that the ticket is invalid and does not output the validity determination signal _S1 , when the non-magnetic ticket holder enters the ticket gate passageway, the no-tag detector 5 operates and is prevented from passing through the ticket gate passageway. Ru.

However, according to this invention, the open switch 7
and a second gate circuit 8 which inputs the output s ₇ of the open switch and the detection signal s ₆ of the entry detector 6 as two inputs under the condition that the non-bill detector 5 is not operating. If the customer has a non-magnetic ticket, the station staff will turn on the release switch 7 based on the customer's declaration.
When operated, the output signal s ₇ of the open switch is input to the second gate circuit 8 .

The station staff turns on the release switch 7 until the passenger passes through the ticket passageway of the automatic ticket gate. At the rising edge of the switch ON, the reversible counter 2 is cleared and becomes 0. Then, when the passenger enters the ticket passage of the automatic ticket gate designated by the station staff, no ticket is currently detected and the output _s6 is at a low level, so the entry detection signal of the entry detector 6 is activated. When s ₅ is input to the gate circuit 8, the second gate circuit 8
is output when the logical condition is satisfied. Its output signal _s8
is applied to the reversible counter 2 via the OR gate 10 as a signal that sets the counter to 1.

Therefore, since the content of the reversible counter becomes "1", the credit signal _s3 is output, and the passage permission condition signal So is output by the operation of the first gate circuit 4.
is output, so the customer can pass through the ticket gate of that automatic ticket gate.

When the vehicle passes through the ticket gate passage, the reversible counter 2 subtracts "1" from the output of the passage detector 3, and its content returns to "0". After confirming that the passenger has passed through the ticket gate, the station staff turns on the release switch 7.
If you turn it off again, the next customer will be subjected to the normal judgment process for magnetic tickets.

If the staff is delayed in responding to the customer's declaration and the customer passes through the entry detection point, it will be detected that there are no bills, an alarm will sound, and an abnormality display will be displayed. Also,
Information boards are posted near the ticket gates telling non-magnetic ticket holders not to insert their tickets into automatic ticket gates and to notify station staff. Since all ticket gates are automatic, non-magnetic tickets may be inserted directly into the ticket gates, and even in that case, when the entry detector is activated, it will detect that there is no ticket, and an alarm will sound and an abnormality display will be displayed.

In such cases, a television camera with a zoom lens, for example, is installed above the automatic ticket gate, and a display or notification is provided to customers to point the ticket returned to the automatic ticket gate in the direction of the camera. By installing equipment that allows the image of a ticket taken by a camera to be enlarged and confirmed on a television set in the monitoring panel, it is possible to check from the television screen that a non-magnetic ticket inserted is determined to be unissued and is prevented from passing. When this is confirmed, turn on the release switch 7, and the no-ticket detection signal _s6 has already been input to the second gate circuit 8 due to the presence of a customer who has entered the ticket gate passageway and been stopped, so the gate circuit 8 does not satisfy the logic condition, but since the logic condition of gate circuit 9 is satisfied, the gate circuit outputs an output, and this output signal _S9 is input to the reversible counter as a signal to set the counter to 1. Therefore, in this case as well, the customers who were prevented from passing are allowed to pass.

When the credit signal _s3 is directly outputted to the reversible counter by the output signal _s7 of the opening switch 7 without providing the second gate circuit 8 and the second gate 9, the non-magnetic If the ticket holder changes his/her will and retreats for some reason before entering the ticket gate passageway or before the release switch is turned on, the credit signal _s3 that has been generated will be retained as is. Therefore, subsequent control may be disrupted.

However, in the automatic ticket gate according to this invention, when the output signal s ₇ of the open switch and the entry detection signal s ₅ satisfy the logical product condition, or the no ticket rejection signal s ₆ , the open switch signal s ₇ , and the entry detection signal s Since the credit signal _s3 is output when each of ₅ satisfies the AND condition, the sudden change as described above does not affect the credit signal s3.

[Effects of this idea]

As mentioned above, according to this invention, when the open switch is operated, the output signal, the no-bill denial signal, and the entry detection signal, or the no-bill detection signal and the open switch signal, each satisfy the logical product condition. In this case, the holder of the non-magnetic ticket operates the release switch either before or after entering the ticket gate, as it is input as an addition signal to the reversible counter in the same way as the validity determination signal for the magnetic ticket. This allows non-magnetic ticket holders to also pass through the automatic ticket gate.

Therefore, unlike in the past, it is no longer necessary to provide an automatic ticket gate passage for magnetic ticket holders and a manned ticket gate passage for non-magnetic ticket holders at one ticket gate, which saves space and labor. savings can also be achieved. Furthermore, since the credit signal is output based on the AND condition of the output signal of the open switch and the entry detection signal, subsequent control will not be disrupted even if the customer cancels his or her intention to pass.
