Abstract

PURPOSE:To prohibit the passage of a third party by detecting the rotational signal of the knob of a door, and judging the permission of the traffic based on information from a body weight meter and the information from a card. CONSTITUTION:A sensor 4 performs communication with a non-contact ID card 3 corresponding to the rotational signal of the knob 1b of the door 1, and a CPU 8c controls the unlocking of the lock 1a of the door 1 by performing collative judgement based on a read ID number and the detection of body weight with the body weight meter 2. Therefore, a traffic permission judging operation included in an ordinary door opening operation is also applied to a passerby. In such a way, a judging processing for passage permission can be performed between the non-contact ID card 3 by radio only by holding and turning the knob 1b even without performing a specific operation by the passerby in traffic control. Furthermore, since the body weight meter 2 is used as a means to specify a passerby principal, individual identification can be performed, which prevents the passage of the third party from occurring.

Description

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

[Conventional technology]

Conventionally, there are devices using ID cards as traffic i14 control devices. In this traffic control device, when you come to the gate, you insert or slide your ID card into a card reader to read and check the ID data, and some also use a push button operation. If the verification result is OK, the person must turn the doorknob and enter the room within a predetermined time.

That is, in conventional traffic control devices, there are two control stages. First, permission is granted based on ID data verification, and second, the door is opened and the gate is opened for a predetermined period of time. There are two stages that must be passed within.
It was a bit cumbersome to operate.

Further, as in Japanese Patent Application Laid-Open No. 63-40074, it is also possible to provide the first passage permission by wirelessly reading the ID card in a contactless manner, thereby eliminating physical contact.

(Problem to be Solved by the Invention) However, when applying the above-mentioned contactless reading of ID cards to a traffic control device, even if a person simply passes in front of a door that controls traffic, a person with an ID card that can be permitted to enter the In this case, there was a problem in that the ID was automatically verified wirelessly and the door was temporarily unlocked.

This invention was made in order to solve the above-mentioned problems, and provides a traffic control device that can automatically control traffic by identifying individuals just by turning a doorknob, which is the normal movement of passing through a screen. This is what we provide.

[Means to solve the problem]

The traffic control device according to the present invention includes a sensor that is installed at the entrance/exit of a door that controls traffic, and that wirelessly reads an ID number from a non-contact ID card owned by a passerby, and detects a rotation signal of a door knob. activating means for activating the sensor; a contactless ID card that is activated by a signal from the sensor and wirelessly transmits the card contents; a scale installed in front of the door; and information from the scale and the card. and determining means for determining whether or not the vehicle is passable based on information from the vehicle.

(Function) In this invention, the sensor communicates with the non-contact ID card in response to the rotation signal of the door knob, and the CPU performs a comparison judgment based on the read ID number and the weight detected by the scale. This controls the unlocking of the door. Therefore, in addition to the normal operation of opening the door, the passerby also performs the operation of determining permission to pass.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows a schematic configuration diagram according to an embodiment of the present invention. In the figure, (1) is a door to which traffic control is to be performed, and is normally locked with an electric lock (1a). Also, this door (
A weighing scale (2) is provided in the front passage of 1). (
3) shows a contactless ID card, which stores an ID number unique to the card, and wirelessly transmits the ID number to the sensor (4) based on a trigger signal wirelessly transmitted from the sensor (4). It is designed to be read as such.

Furthermore, (5) sends a start signal to the sensor (4) to start ID discrimination and traffic control operation based on the input of the rotation signal of the knob (1b) of the door (1). The passage activation means starts the reading operation of the ID number of the contact ID card (3), and the reading data of the ID number by the sensor (4) is sent to the passage judgment means (6), and the passage judgment means (6) The above read data is compared with specific data stored in advance, and at this time, the contactless ID
The body weight detected by the scale (2) of the person holding the card (3) is compared with the stored data to identify the individual and make a traffic judgment. The lock is unlocked by sending out the unlock signal (1a). Note that when the determination is NO, the alarm means (7) is activated.

FIG. 2 shows a hardware configuration diagram of the above embodiment, in which rotation signals from the knob (1b) and detection data from the weight scale (2) are input, as well as an unlocking signal to the electric lock (la) and an alarm means.

and a serial interface (8e) for transmitting data to the host computer (9).

Next, regarding the operation related to the above configuration, the CPU shown in FIG.
This will be explained with reference to the operation flowchart (8c).

First, in step S1, a passerby presses the knob (1b) of the door (1).
) is detected, and in step S2 the radio device (8d
) sends a trigger signal to the contactless ID card (3) to request transmission of the card's unique number. Based on this, the card unique number is received from the contactless ID card (3) (step S3), and the card unique number is stored in the memory (step S3).
It is determined whether or not it is registered in the "traffic permit ID number table" in step 8b) (step S4). If NO, an alarm signal is output to the alarm means (7) for a certain period of time (step S5). Further, in the case of YES in step S4, it is determined whether the detection signal from the scale (2) is within a certain range of the value of "personal weight and clothing" stored in the memory (8b). SS), in the case of No, an alarm signal is output to the alarm means (7) in the same manner as described above. On the other hand, in the case of YES in step S6, an unlock signal for the electric lock (1a) is output for a certain period of time (step S7). Therefore, by simply stepping on the weight scale (2) and turning the knob (1b), a passerby is automatically identified and allowed to pass through the door (1). Incidentally, step S8 is a process for determining whether the knob rotation signal is OFF or low; if YES, the process waits for the next entry into the room. Further, the "traffic permit ID number table" and "personal weight and clothing" may be downloaded from the host computer (9).

[Effects of the Invention] As described above, according to the present invention, in traffic control, the process of determining whether or not a passerby can pass can be performed by simply grasping and turning a knob without requiring any specific operation by the passerby with a contactless ID card. This is made possible by wireless technology, and since a scale is used to identify the person passing by, it is possible to identify the individual and prevent others from passing, allowing for natural operation in an access control system.
