Description

The present invention relates to a traffic control device using an ID card whose memory contents can be rewritten.

[Conventional technology]

Conventionally, as a device of this type, a non-contact IC card is used, and when discriminating the contents of the card, there is a device in which all discriminating conditions are stored in a card reader or a host computer for comparison and discrimination.

[Problems to be Solved by the Invention]

However, in the above-described conventional device, all the determination conditions are stored in the card reader or the host computer, so that the memory capacity becomes large and the cost becomes high, and the data response speed is slow.

Therefore, the present invention has been made to solve the problems in the conventional example as described above, and provides a traffic control device capable of reducing the memory capacity of the host computer and the card reader and speeding up data access. Is.

[Means for Solving the Problems]

The traffic control device according to the present invention stores the basic information of the ID and the auxiliary information of the valid period and the valid time zone in the memory and allows the rewriting of the memory content, and permits the traffic.
It stores the basic information of ID, and when reading the contents of the ID card,
If there is an instruction to change the above-mentioned accessory information when the matching result of the basic information of the above ID matches, the accessory information is rewritten in the memory of the ID card according to the instruction and the valid period and valid time zone of the accessory information stored in the ID card Characterized by including a card reader that determines the ID to control the passage of traffic, and a host computer that transmits data between the card reader and gives an instruction to change attached information to the ID card. Is.

[Action]

According to the traffic control device of the present invention, only basic information (ID number) is stored in the host computer or the card reader,
Since other information is stored in the ID card, data can be accessed quickly, and the memory capacity of the host computer or card reader can be reduced.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1 (a) and 1 (b) show the structure of a traffic control device according to this embodiment. In FIG. 1, (1) is a host computer, which stores a CPU (1a), programs, and the like. ROM (1b), basic information (ID number)
A printer (1c), a clock (1d), a transmission interface (1e) for exchanging data with a plurality of card readers (21) to (2n), and a printer It has (1f), CRT (1g) and keyboard (1h).

Further, (2) is a card reader that generically indicates the first to n-th card readers, and this card reader (2) stores a CPU (2a), a program (ROM), etc.
b), RAM (2c) that stores ID number data, etc., fountain clock (2d), input / output interface (2e) for controlling electric lock (4), transmission interface with host computer (1) It incorporates a communication device (2g) that exchanges data with (2f) and the contactless IC card (3) by wireless transmission.

Further, (3) indicates a non-contact IC card as an ID card, and the non-contact IC card (3) includes a CPU (3a), a ROM (3b) in which programs and the like are stored, a RAM (3c), It has a built-in communication device (3e) that exchanges data with the battery (3d) and the outside by wireless transmission. The RAM (3c) has an ID number, valid period, valid area (passable door) and valid. The time zone etc. is written at the time of registration.

The operation of the above configuration will be described based on the flowchart of FIG. FIG. 2A shows each card reader (21) to
It shows the operation of writing the ID number of the card (3) to the (2n) from the host computer (1) at a predetermined cycle. First, transmission is started with the first card reader (21) (step S2a ₁ ), You can pass this first card reader (21)
RAM that receives the ID number from the host computer (1)
Stored in (2c) (Step S2a _2). And then the second
Start transmission with the card reader (22) (step S2
a ₃ ), the same processing as that of the first card reader (21) is performed (step S2a ₄ ), and the same processing is performed until the n-th card reader (2n) until a predetermined time has elapsed (steps S2a ₅ , S2).
a ₆ ).

Next, when an addition or deletion card is generated, the process is performed as shown in FIG. 2 (b). Addition or deletion is input from the keyboard (1h) of the host computer (1), CPU (1a)
, Based on which to determine whether there is newly added / deleted ID number (step S2b _1), selects a card reader (2) of the ID number is passable (Step S2b _2). Then add / deletes the ID number in the RAM (2c) of their card reader (2) (Step S2b _3).

Further, when changing the valid period and time zone stored in the card, it is performed as shown in FIG. 2 (c).

To determine to change the expiration period and time zone of the host computer (1) is card (3) (Step S2c _1), the card (3) is a card reader (2) with ID number navel data of traffic flow in sending (step S2c _2). Then, the data is stored in the RAM (2c) of the card reader (2) (usually the card reader does not store only the ID number) (Step S2c _3).

Further, based on these, the processing by the card reader (2) during passage is performed as shown in FIG. 2 (d). First, read the card (3) (Step S2d _1), checks the ID number (step S2d ₂₎ (is now automatically effective area is determined). If the matching results match, the host computer (1)
From the effective to the card reader (2) period, it is determined whether or not there is a change instruction of the availability window (step S2d _3), also validity period read, the time zone to determine OK or not (step S2d ₄₎ , and then proceeds to step S2d _5. At this time in the case of YES at step S2d ₃ proceeds to step S2d ₅ by changing the data in the RAM (3c) of the card (3), and sends the electric lock unlocking output. Then, it is determined whether the door is opened within the predetermined time (step S2d _7), if yes regarded as the person was passing (step S2d _8). In the case of no that person is deemed not to have been passing (step S2d _10). At this time, the transmission data of the passerby to the host computer (1) to (Step S2d _9), the host computer (1) side can either view the data in CRT, make the like to be output by the PRT.

In addition, this invention can implement the following aspects.

1) Any card that can rewrite the contents of the memory can be used.

2) When a numeric keypad or a fingerprint discriminator is also used, the personal identification number and the fingerprint characteristic parameters can be stored in the card and processed in the same manner.

3) If you do an anti-passback check (an intruder who tries to enter by opening a check card that the same person will come in again even if you are not out of the door you entered), which door was entered / exited May be stored in the memory of the card and checked by a card reader.

4) Not only the data of people who pass by, but also the data of NO-GO people may be stored in the host computer and used for operation. In addition, all data of people who pass by (passing date and time, validity period
The effective area etc.) may be printed out by the host computer.

〔The invention's effect〕

As described above, according to the present invention, the ID card in which the memory contents can be rewritten stores the basic information of the ID and the auxiliary information of the valid period and the valid time zone, and the card reader and the host computer store the ID. By storing only the basic information, the contents of the ID card are read by the card reader, and the ID is discriminated based on the collation of the basic information of the ID and the valid period and the valid time zone of the attached information to control the passage. Therefore, it is not necessary to store all the determination conditions for traffic control on the card reader and the host computer side, so that the memory capacity of the card reader and the host computer can be made small and data access can be accelerated. In addition, according to the change instruction from the host computer, the ID card attached information can be Since the rewritable, it is possible to restrict the use of unavailable ID card by loss, etc., it can also combine the effect of increasing the security.
