Description

The present invention relates to a card judgment device for judging the validity of a card inserted in a card reader.

(B) Conventional technology As a card determination device, there is, for example, a device for controlling traffic using a card.
There is disclosed a device that detects an individual code of a passage card with a card reader and compares the detected code with a predetermined parameter to control passage, that is, to ensure security.

(C) Problems to be Solved by the Invention However, even in such a system that secures security by using a card, it may not always be necessary to maintain security depending on the situation.
For example, considering the case of applying a card system that applies to a company's general purpose gate, it is rare for a suspicious person to enter at work, but even in such a case, you must use a card every time you come to work. If you have to receive a decision to release security, you will have a line in front of the entrance gate and you will not be able to come to work smoothly.

Therefore, the present invention provides a card determination device that can unconditionally cancel security according to the date and time.

(D) Means for Solving the Problems In order to solve the above problems, a card determination device according to the present invention includes a card reader, a terminal control device connected to the card reader, and a host that integrally controls the terminal control device. A controller, the host controller includes an input device for inputting a security release period, and when the input security release period is reached, a command indicating the security release is transmitted to the terminal device, and when the security release period ends, the security is terminated. And a card check unit for performing a check process on the card data read by the card reader by using preset parameters, and a transmitting unit for transmitting a command indicating a tea set. If the validity of the card is confirmed at And a processing unit for instructing to release the security and for instructing to release the security until the command for instructing the security is transmitted from the host controller until the command for instructing the security set is transmitted.

(E) When a card is inserted into the working card reader, the card checking means checks the card data read by the card reader with preset parameters to determine whether the inserted card is valid or invalid. . Then, when the processing means determines that the card checking means is a valid card, the processing means releases the security.

When the security release period is input by the input device, the processing means always performs the security release process during the release period regardless of whether or not the card is inserted.

(F) Example The present invention will be described below with reference to an example of a traffic control device.

In FIG. 1, 1 is a center, and 2 is a terminal device which is managed by the center 1 and controls direct traffic.

On the side of the terminal device 2, reference numeral 3 denotes a gate mechanism, which is specifically constituted by a door, and is normally held in a closed state by an electric lock mechanism 4. In this example, by controlling the unlocking of the door 3, for example, traffic to a room or the like is managed. Reference numeral 5 denotes a hand-scan type card reader, on the front surface of which are provided a running groove 6 for inserting an ID card for scanning, and an OK indicator 7 and an NG indicator 8 for displaying validity / invalidity of the scanned card. I have. This ID card records data for identifying an individual. The lock mechanism 4 and the card reader 5 are
Each is connected to the terminal control device 10.

The center 1 is provided with a host controller 11, a clock circuit 12, a transmission control unit 13, and an input device 15, which are upper control devices, and the host controller 11 is connected to the terminal control device 10 of the terminal device 2 through a cable 14. There is. Then, in the center 1, the personal data of the person who is allowed to pass is input device 15
Input to the host controller 11, the transmission control unit
13 is activated, and the personal data input via the cable 14 is transmitted to the terminal device 2. This personal data becomes a parameter used when checking the validity of the card in the terminal device 2. Such an operation of transmitting personal data is performed, for example, when the power to the host controller 11 is turned on or at a predetermined time, in addition to the input of the personal data.

Further, the host controller 11 stores the period when the security is released by the input device 15 and stores the period, and the period data and the real-time data indicating the current date and time sent from the clock circuit 12 at regular intervals. , And if the start date and time of the release period match, the transmission control unit
When 13 is activated, a command indicating the security release is transmitted to the terminal device 2, and when the end date and time of the release period match, a command indicating the security set is transmitted to the terminal device 2.

As shown in FIG. 2, the terminal control device 10 includes a CPU 20 and an R
It includes an AM21, a ROM 22 storing an operation program, and an I / O interface circuit 24. The lock mechanism 4 described above,
The transmission controller 25, which communicates data with the host controller 11 through the card reader 5 and the cable 14, is
It is connected to the CPU 20 via the O interface circuit 24.
The RAM 21 includes an area as parameter storage means for storing personal data transmitted from the center 1.

Fig. 3 shows C according to the program stored in ROM22.
7 is a flowchart showing a door lock control process performed by the PU 20, wherein the CPU 20 has a function as a card check unit for performing a check process on the card data read by the card reader 5 by the parameter stored in the parameter storage unit, and a card check. The means has a function as a processing means for performing security release processing when the means determines that the input card is valid and during the security release period, which will be apparent from the following description.

First, in step S1, the CPU 20
It is determined whether or not the parameter is transmitted from, and if it is transmitted, the parameter is received in the next step S2 and stored in the area of the parameter storage means of the RAM 21.

Then, in step S3, the CPU 20 causes the host controller 1
It is determined whether or not the command is transmitted from 1, and if it is not transmitted, the process proceeds to the next step S8, but if it is transmitted, the process proceeds to step S4. In this step S4, the CPU 20 releases the security (OF
Those that indicate F) or a set of security (O
N) is indicated. When the security is released, the CPU 20 sets the security release flag in the register held therein in step S5 and gives an unlock signal to the lock mechanism 4 in the next step S6. This allows the lock mechanism 4 to open the door 3 and enter the door in order to unlock the door 3. In the next step S9, the CPU 20 determines whether or not the security release flag is set, and if it is set, the process returns to step S1. Therefore,
When the security release command is sent from the host controller 11, the CPU 20 does not perform the card processing, and holds the lock mechanism 4 of the door 3 in the unlocked state. In this case, a person who has passed through the door 3 can open the door 3 and enter at any time without inserting the card into the card reader 5.

When the host controller 11 sends a security set command to the terminal control device 10,
In step S7, the CPU 20 resets the security release flag, and in step S8, the lock mechanism 4 is reset.
Give a lock signal to. This will take you to the next step
After the determination in S9, the processing of the CPU 20 proceeds to step S10, so that the door 3 which has been in the free state until now is locked by the lock mechanism 4
Locked by and will not open unless a valid card is thrown in.

The operation of controlling the door lock by the card inserted into the card reader 5 will be described.

When the ID card is inserted into the card reader 5 in step S10, the recording data of the card read by the card reader 5 is input to the CPU 20 in step S11. In the next step S12, the CPU 20 determines the validity of the card by comparing the recorded data of the card with the data transmitted from the host controller 11 and stored in the area of the parameter storage means of the RAM 21. Then, if the card is valid, the process proceeds to step S14, and the CPU 20 gives a drive signal to the OK indicator 7 to perform the OK display. If the card is invalid, the process proceeds to step S13 and the CPU 20 issues the NG indicator 8 to perform the NG display. Drive signal to.

Drive the OK indicator 7 when the card is valid and step
When proceeding to S15, the CPU 20 gives an unlock signal to the lock mechanism 4. This allows the lock mechanism 4 to open the door 3 and enter the door in order to unlock the door 3.

When the door 3 is opened, it is automatically closed. When the door 3 is closed, a closing signal is output from the lock mechanism 4 to the CPU 20. Therefore, in step S16, the presence or absence of this closing signal is determined, and if there is no closing signal, step S17
After locking the door 3 by proceeding to step S1, the process returns to step S1.

As described above, the card determination device according to the present embodiment is configured by the host controller 11 and the terminal control device 10 when installed in the center 1, so that the device (the door 3 in the embodiment) whose security is controlled can be controlled. When there are multiple, there is an advantage that the host can collectively control the security release period and security assurance.

(G) Effect of the Invention According to the present invention, since security is automatically canceled during a period when security is not required to be secured, a card system can be provided in which the check of the card can be omitted and the efficiency is high. be able to.
