Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention 1 (Industrial Application Field) The present invention relates to a traffic management device that wirelessly reads card information on an identification card, discriminates the read card information, and controls the opening and closing of a passage door. .

(Prior Art) Generally, as a traffic control device that automatically controls who enters a place that requires secrecy, passersby are required to carry an identification card on which card information such as their own ID (identification) code is magnetically recorded. , a passerby is made to read the card information of the identification card with a card reader placed near the passage door, and when the read card information is predetermined passage permit card information, the passage door is opened. ing.

However, it is very cumbersome for passersby to take out their identification cards from their pockets and have them read by a card reader each time they pass through this traffic management device, and if a passerby's hands are contaminated when leaving, the identification card cannot be read. Therefore, a traffic management device has been proposed in which the traffic management device is equipped with a card reader that automatically reads card information wirelessly, and passersby are required to carry identification cards that can be read by the card reader. There is.

5 to 7 are schematic configuration diagrams of a traffic management device incorporating a card reader for wirelessly reading card information. A pair of direction control doors 2a, 2b are provided along the passageway 1, and a rotary passage door 3 is provided at an intermediate position between the direction control doors 2a, 2b. A total of four card readers 5a. 5b,5
c, 5d are attached.

Sensors 6a and 6b using phototubes, for example, detect passersby on the outside of the pair of direction control doors 2a and 2b.
are provided, and are automatically released when a passerby approaches each direction control door 2a, 2b.

Further, each card reader 5a to 5d attached to each side wall 4a and 4b applies an electromagnetic field 8a, 8b, 8c, and 8d having predetermined information to each card at a constant intensity as shown by the shaded area in FIG. It is generated before and after the readers 5a to 5d. In fact, the back and side surfaces of each card reader 5a to 5d are covered with an electromagnetic shielding member 9 so that the electromagnetic fields 8a to 8d generated by each card reader 58 to 5d do not spread outside the passage 1. It is being said. And each electromagnetic field 8a, 8
b. The areas of 8c+8d are set so that they do not overlap with each other.

For example, each of the electromagnetic fields 8a, 8b. 8c and 8d are embedded with transceivers that respond to each other, and upon receiving the electromagnetic field information, transmit the card information set for itself. By receiving the card information, the card readers 5a to 5d can read the card information of the identification card carried by the passerby.

The passage door 3, the direction control door 2a. 2b and each card reader 5a to 5d are controlled by a control section 10 consisting of, for example, a microcomputer.

In such a traffic control device, when a passerby approaches the direction control door 2a, the direction control door 2a is released and the passerby enters the direction control door 2a.

Then, a passerby enters the area of the electromagnetic fields 8a, 8c of one of the card readers 5a, 5c, so that, for example, the card information of the identification card stored in the passerby's chest pocket is transferred to one of the card readers 5a, 5c. It is read by card readers 5a and 5c. The read card information is sent to the control unit 10, and it is determined whether or not the card information allows passage. If the card information allows passage, the passage door 3 and the other direction control door 2b are opened.

The passerby then passes through the opened passage door 3 and direction control door 2b and exits.

With a traffic management device configured like this, passersby carrying identification cards do not have to perform any card reading operations.
You can pass through this traffic control device.

However, even with the above-mentioned traffic management device, there still exist the following problems. That is, the card reader 5
Since it is necessary to prevent the electromagnetic fields 8a to 8d output from the directional control doors 2a from leaking out of the passage 1, it is necessary to use a card reader whose electromagnetic fields are not very strong. , 2b, it is necessary to reduce the unreadable area as much as possible. As a result, as shown in FIG. 7, a plurality of card readers 5a, 5b, 5c, 5d
must be installed, resulting in the problem of increased equipment costs.

Furthermore, as shown in FIG. 7, in the center of the passageway 1, the area beyond the reach of the electromagnetic fields 88 to 8d is wide, and the identification cards cannot be read sufficiently by the card readers 5a to 5d when passing. The probability that a reading error will occur increases. In addition, if the electromagnetic fields 88-8d of each card reader 5a-5d overlap, each electromagnetic field 88-8d will cause interference and a reading error will increase conversely.

(Problem to be solved by the invention) The present invention has been made in view of the above circumstances,
By attaching card readers to passage doors, the number of card readers installed can be reduced, manufacturing costs can be reduced, and the readable range in the center of the aisle can be increased, reading errors can be significantly reduced and reliability can be increased. The purpose is to provide a traffic management device that can improve traffic performance.

In order to solve the above problems, the traffic control device of the present invention includes a pair of direction control doors spaced apart along the passage, a traffic door provided in the middle of the pair of direction control doors, A card reader which is attached to a passage door, whose reading area extends to a predetermined area on both sides of the passage door, and which wirelessly reads card information of an identification card carried by a passerby who has entered the inside of the directional control door; A passage door opening/closing control means that opens the passage door when the card information read by the device is predetermined passage permit card information, and a passage door opening/closing control means that opens the passage door when the card information read by the device is predetermined passage permission card information, and when a passerby is present inside one of the direction control doors, the other direction. and directional control door release prohibition control means for prohibiting release of the control door.

(Function) In the traffic management device configured in this way, a card reader is attached to the traffic door. The reading area of this card reader extends to both sides of the door. Therefore, no matter which direction a passerby carrying an identification card approaches the passage door, the card information on the identification card is read by the card reader. The opening/closing of the passage door is then controlled in accordance with the read card information.

Furthermore, if a passerby is present inside either one of the directional control doors, the other directional control door will not be released. Therefore, passersby are prevented from entering the traffic management device from both directions at the same time.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

Figures 1 to 3 are diagrams showing the traffic management device of the embodiment. Figure 1 is a schematic diagram showing the general configuration, Figure 2 is a three-dimensional perspective view, and Figure 3 is a diagram showing the electromagnetic field of the card reader. It is a figure showing the range covered. A pair of direction control doors 12a, 1 along the passage 11
2b is provided, and its direction control doors 12a, 12b
A rotary passage door 13 is disposed at an intermediate position. This passage door 13 has side walls 14a on both sides of the passage 11,
The rotation mechanism 13b is attached to one side wall 14b of the rotation mechanism 14b. A window 13a is provided in the center of the passage door 13, as shown in FIG. 2, and a card reader 15 is disposed within this window 13a.

The case of the card reader 15 is made of a non-metallic material such as acrylic or FRP that allows radio waves and magnetic fields to pass through with almost no obstruction. Therefore, this card reader 15 generates electromagnetic fields 18a and 18b having parabolic regions (reading regions) as shown by diagonal lines in FIG. 3 on both sides of the passage door 13.

Further, as described above, each electromagnetic field 18a. A transmitter/receiver is embedded in 18b, and upon receiving the electromagnetic field, transmits the card information set for itself.

By receiving the card information, the card reader 15 can read the card information of the identification card carried by the passerby. The card information read by the power card reader 15 is sent to a control section 20 consisting of, for example, a microcomputer.

The pair of direction control doors 12a. A sensor 16a using a phototube, for example, detects a passerby outside the sensor 12b.
．． 16b is installed so that passersby can access each direction control door 12.
a, 12b, the sensors 16a, 16b detect and send a detection signal to the control section 20.

The opening and closing operations of the passage door 13 and the direction control doors 12a and 12b are performed in response to commands from the control section 20.

When the power of the apparatus is turned on, the control section 20 is programmed to control the opening and closing of each door 12a, 12b, 13 according to the flowchart shown in FIG.

When the flowchart is started and a passerby detection signal is input from the sensor 16a installed on the outside of one direction control door 2a in S (step) 1, the corresponding direction control door 1 is stored in the storage unit.
2a is set to a release prohibited state.

If the release prohibition state is set, the other direction control door 1
Since there is a passerby inside door 2b, the corresponding direction control door 12a will not be released until the release prohibition state is canceled.

If the release prohibition state has been canceled, this direction control door 12
Release a for a certain period of time. Then, the direction control door 1 on the opposite side
Set the release prohibition state for 2b.

Next, in S2, when card information is input from the card reader 15, it is checked whether this card information matches the pass permit card information stored in advance in the storage section. S
If they do not match in step 3, the passerby carrying this identification card will not be able to pass through this traffic control device, so pass through door 13.
The rear direction control door 12a is opened for a certain period of time without opening the door. When a passerby exits the direction control door 12a, the release prohibition state of the other direction control door 12b is released. Then return to the beginning of the flowchart.

If the card information read in S3 is pass permission card information, the passage door 13 is released for a certain period of time, the release prohibition state for the other side directional control door 12b is canceled, and then the opposite side directional control is performed. The door 12b is opened for a certain period of time.

Then, when a passerby exits the direction control door 12b,
Return to the beginning of the flowchart.

Then, in S4, when a passerby detection signal is input from the sensor 16b outside the direction control door 12b on the opposite side, S4
After confirming that the release prohibition state for the opposite direction control door 12a is not set in step 5, the corresponding direction control door 1 is opened.
Release 2b and lead the passerby inside.

With the traffic control device configured in this way, when a passerby with an identification card stored in, for example, a chest pocket approaches the direction control door 12a, unless the passerby has already entered from the opposite side, the direction control is performed. Door 12a is automatically opened. When a passerby enters the direction control door 12a, approaches the passage door 13, and enters the electromagnetic field 18a of the power card reader 15, the card information of the identification card is automatically read. and,
If the card information is pass permit card information, pass door 13
And the direction control door 12b on the opposite side is automatically opened. Therefore, passersby pass directly through this traffic management device.

The same applies when passing through this traffic control device from the opposite side.

In addition, each direction control door 12a. 12b as necessary,
Since the transition to the release prohibited state is controlled, passersby are prevented from entering the traffic management device from both directions at the same time.

Furthermore, in such a traffic management device, there is only one card reader 15 attached to the window 13a of the passage door 13. Therefore, the number of parts can be significantly reduced compared to the conventional device shown in FIG. 5, and therefore manufacturing costs can be significantly reduced.

Furthermore, since the card reader 15 is installed almost in the center of the passage 11, there is a small probability that the electromagnetic fields 18a and 18b will leak outside the passage 11, unlike in the conventional apparatus. No parts needed.

Furthermore, as shown in FIG. 3, the electromagnetic fields 18a and 18b generated by the card reader 15 spread in a parabolic shape symmetrical to the center line of the passageway 11, so passersby can walk straight in the center of the passageway 11. . In other words, like the conventional device,
There is no need to face the side wall where the card reader is installed.

Then, a passerby receives the electromagnetic field 18a, 1 of the card reader 15.
8b is also much longer than conventional devices, the card reader 15 can reliably read the card information on the identification card, greatly reducing the probability that the card information will be read incorrectly. Can be reduced.

[Effects of the Invention] As explained above, according to the traffic management device of the present invention, by attaching the card reader to the passage door, reading areas can be provided on both sides of the door, and the reading area can be placed in the center of the passage. It can be set to Therefore, the number of installed card readers can be reduced to one, which allows the configuration to be simplified and manufacturing costs to be significantly reduced. Furthermore, since the readable range in the center of the aisle can be increased, the probability of erroneously reading identification card information can be significantly reduced, and the reliability of the entire device can be improved.
