Abstract

PURPOSE:To control passing rapidly by announcing that both men can pass when the two men are read simultaneously and ID collation of both the men is OK. CONSTITUTION:A card reader 3A has a CPU 3Aa, ROMs, 3Ab and 3Ad to store a program, etc., a RAM 3Ac to store ID number data, information about the present position of a passerby, etc., a communication device 3Ae to give and receive data by radio transmission in which a reader head part is built, an input/output interface 3Af to control an auto-announce device 1 and an electric lock 5 and a transmission interface 3Ag. When non-contact IC cards 2 of the two men are read simultaneously and the ID collation is OK, an anti bus back is checked based on the information about the present position of the passerby stored in the RAM 3Ac based on the control of the CPU 3Aa, further, when the check is OK, the electric lock 5 is unlocked, the auto-announce device 1 is activated to announce that both men should pass simultaneously and thus, the passing is controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a traffic control device that controls traffic using, for example, a non-contact ID cart such as a non-contact IC card.

[Prior Art] Conventionally, there are traffic control devices using non-contact IC cards. With this non-contact IC card, it is possible to lead two people at the same time, and in this case, even if only one person's ID is verified and the other person is not, they can pass at the same time. Furthermore, even when ID verification is OK for both passengers, they are not notified to pass together, resulting in cases where two people pass at the same time and cases where one person passes at a time, causing problems with anti-bus backing. Furthermore, it takes time for each person to pass through the area one by one.

[Problem to be solved by the invention]

As mentioned above, in the conventional traffic control device, there is a problem in that when two large vehicles lead the traffic at the same time, it takes a long time to pass and a problem arises in anti-busback.

Therefore, this invention was made to solve the problems in the conventional example as described above, and is a traffic control system that can perform traffic control quickly without causing the problem of anti-busback even when two types of traffic control are performed at the same time. It provides equipment.

[Means to solve the problem]

A traffic control device according to the present invention is a traffic control device that controls traffic by reading ID number data stored in a contactless IC card and comparing it. It sometimes controls the door to be unlocked upon ID verification.

[Effect]

According to the traffic control device of the present invention, two people can lead at the same time, and when both ID verifications are OK, an announcement is made for the two people to share the same line, so traffic control can be performed quickly.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
Figures (a) and (b) show the overall schematic diagram of this invention, and (1
) is an auto-announcement device installed on the ceiling of the door (4) that controls access to important areas, (38), (3B)
are card readers on the entrance and exit sides that read the contactless IC card (2), (4) is the door, and an electric lock (5) is provided inside the handle of the door. The ID numbers are read and verified by card readers (3A) and (3B), and when the verification results match, the electric lock (5) is unlocked and the door (4) is opened to allow passage.

FIG. 2 shows a specific internal configuration diagram of each of the above parts, and the non-contact IC card (2) includes a CPU (2a),
A ROM (2b) that stores programs, etc., a RAM (2c) that stores ID number data, etc., a battery (2d), and a communication device (2e) that exchanges data with the outside via wireless transmission. Built-in.

In addition, the card reader (3A) has CPt1 (3Aa
), ROM that stores programs, etc. (3Ab)
(3Ad), a RAM (3Ac) that stores ID number data and current location information of passersby, a communication device (3Ae) that has a built-in reader head and sends and receives data via wireless transmission, and an auto-announcement device (1). ) and human output interface (3Af) that controls the electric lock (5)
, and a transmission interface HA g), which can read two people's contactless IC cards (2) at the same time and check their IDs.○
Sometimes the RAM is stored under the control of the CPU (38a).
It checks the anti-busback system based on the passerby's current location information stored in the (3Ac), and when the check is OK, it unlocks the electric lock (5) and activates the auto-announcement device (1). If the door (4) is opened within a predetermined time, it will be assumed that both people have passed through the important area and the above current location information will be removed. It is possible to change the data from to within.

In addition, the data of passersby who passed at this time is sent to the exit side card reader (3B) via the transmission interface (3Ag).
It is designed to be transmitted to

The exit card reader (3B) also has the same configuration as the entrance card reader (3A) and operates in the same way.

The operation related to the above configuration will be explained based on the flowchart of FIG. 3. Read the non-contact IC card (2) by the card reader (3A) on the population side (531) L. If there is only one person, check if there is one person (532), if there is one person, check the ID number and if OK (S33) , RAM (3Ac
) to determine whether the passerby is inside based on the passerby's current location information stored in the anti-bus back check) (S34), and if there is (:PU
Unlock the electric lock (5) based on the control of (3Aa) (
S35), and on the condition that the door (4) is opened within a predetermined time (536), the current position information indicating that the passerby has entered is changed (537). In addition, the passerby's card is read by the exit side card reader (3B) and the ID is read.
When the verification is OK and the door (4) is opened, the passerby has gone outside, and the current position information is reset. The traffic control up to this point is for one person.

Next, if two people's cards are read instead of one person's card (538), and both ID verification is OK (S39), the Check the bus back (S40), and if the bus is not inside, unlock the electric lock (5) (S41), activate the auto-announcement device (1) (S42), and let the bus pass when two people are together. Announce that you will. and again,
Condition is that the door (4) is opened within a predetermined time (S43)
, the current location information is changed to indicate that both people have entered the room (
S44). Please note that the exit side card reader (3B)
The cards of the passersby were read, ID verification was successful, and when the door (4) was opened, the two passersby went outside.
The above current location information will be reset.

This invention can also implement the following aspects.

(1) The contactless card can be used not only for IC cars but also for other contactless cards (such as battery-less ID cards that use resonant coils or ultrasonic transducers).

(2) The same can be done with an ID card without a battery, that is, a type that rectifies the received radio waves and uses it as a power source.

(3) The same can be done with ID cards that use light.

(4) The same effect can be achieved by using a numeric keypad or biometric ID sensor in combination with the ID card.

(5) You can do the same with automatic doors instead of electric locks.

(6) A display may be used instead of auto-announcement.

(7) When there are more card readers, anti-passback processing may be processed by HO5T-CPII.

(8) If two people come and only one is OK, you can make an announcement so that only that person can pass.

(9) It is possible to detect whether two people have passed by using a charging device or by pattern recognition of ITV images, and then determine that two people have passed by.

(to)'If two people do not pass, (only one person passes) and the other person reads the card immediately, the anti-passback function may not be activated.

(11) It goes without saying that the movement when leaving a room is the same as when entering.

〔Effect of the invention〕

As described above, according to this invention, two people can lead at the same time, and when both ID verification is OK, an announcement is made that the two people should go to the same line, and when the door opens, the anti Problems such as passbacks do not occur, and passing can be done quickly.
