Due to the characteristics of the magnetic card, it is difficult to record a lot of information such as personal information and conditions of entry, so that it is difficult to manage slowly and slowly, and it is easy to steal or forge a lost card. In addition, the entry and exit information was recorded in the magnetic area to make sure that the storage was secured. (The information recorded in the magnetic area is also lost by an object such as a magnet).

If the magnetic card is lost because it is not easy to change the room information and the room condition information of a specific room, there may be a problem of exchanging the door control key to prevent the use of the lost card.

Accordingly, an object of the present invention is to provide a door control system and a method of controlling the same, which records personal identification information and entry conditions on a semiconductor chip card, and controls entry control based on entry conditions information of the card.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

And the lead / light unit 20 for recording or reading information on the chip card, and the access control information of the input system, and the access control information of the card read from the lead / light unit 20; Comparing unit 22 for comparing the access control information of the stem to determine whether the card is entered, the access control information and system information of the input system and the information from the keypad 18, and the lead / write unit ( 20 is controlled to access information to the IC card 21, and the access control information of the card read therefrom is input to the comparison section 22, and the door opening / closing control is performed by the access decision information from the comparison section 22. Opening and closing unit 28 that is driven by a signal to open and close the door, and the buzzer 30 to alarm the door opening under the control of the control unit 24.

The system access control information in the above-described configuration is access control information output from the PC 12, such as a job title code, a department code, a lost card code, and the like. The card access control code is a personal identification code (number) and job title code. , Department codes and personal information.

The code output from the PC 12 is input to the comparator 22 through the repeater 14, the address discriminating unit 26, and the control unit 24, and the access control information of the card is controlled by the control unit 24. The lead / light part 20 accesses.

2 is an operation flowchart of the control unit 24 of FIG.

An operation example of the present invention will now be described with reference to FIGS. 1 and 2.

When power is applied to FIG. 1 now, the controller 24 performs the initial process of FIG. 2A to set its own address (unique address) and data transfer rate in the internal memory, and transmits a control signal to the switch 28. Print out to see if the door is open.

If the door is open, the control unit 24 controls the buzzer 30 to ring the buzzer to alarm that the door is open.If the door is normally closed, the door state display is set to the initial position, that is, the closed display in the process of 2B. do.

When the operation is finished, the control unit 24 searches whether there is a command from the PC 12 through the address discriminator 26 in step 2C, and if there is a command from the PC 12, the control unit 24 performs the command in 2D.

If there is no command in step 2C, the lead / light 20 is checked to check whether the IC card 21 is inserted in step 2E.

At this time, the lead / light unit 20 transmits the information to the control unit 24 when the IC card 21 is inserted.

When the insertion of the card 21 is detected in the lead / light unit 20, the controller 24 supplies power to the chip in the IC card 21 through the lead / light unit 20 in 2F, and then 2G. In the process, the control unit 24 is placed in a state of inputting a personal identification number, and a personal identification number is received from the keypad 18.

If the insertion of the card 21 is not detected in the lead / light unit 20, the process of 2C is repeated.

The personal identification code (number) is generated by a person pressing a key on the keypad 18.

The controller 24 transmits the personal identification code inputted from the keypad 18 to the comparator 22, and the comparator 24 is connected to the chip in the IC card 21 through the lead / light unit 20. The output information of the recorded card is read and transmitted to the comparison unit 22.

At this time, the comparison unit 22 compares the personal identification number of the keypad 18 output from the control unit 24 with the personal identification code in the access information and outputs information on the result to the control unit 24.

The control unit 24 outputs the comparison information of the state where the personal identification number is different from the personal identification number recorded in the IC card 21 in the comparison of the comparison unit 22 as the comparison result information output from the comparison unit 22. In one state, the control unit 24 outputs an error message to the display device of the opening / closing unit 28, and controls the lead / light unit 20 to discharge the inserted IC card 21 in 2L.

If the personal identification code (number) matches, it is determined that the input key is valid in the above-described process of 2H, and the read / write unit 20 is controlled in the process of 2I to read the first data in the IC card 21 and compare unit 22 ) And inquire about admission conditions in 2J.

Data transmitted by the process 2H is also compared with invalid card data (Invalid card Data) in the comparator 22, and the result is transmitted to the controller 24.

If registered in the invalid card data list, the comparison unit 22 transmits the invalid data to the control unit 24. At this time, the control unit 24 determines that the accident card is an IC card with an error message in the 2L process. The card 21 is automatically ejected from the lead / light unit 20.

The envelope card data is data stored in the memory area of the comparator 22 through the repeater 14, the address discriminator 26, and the controller 924 by outputting lost card information from the PC 12.

If not in the envelope card list, the comparison unit 22 transmits information to the control unit 24 that the card is valid.

At this time, the entrance condition can be inquired in the above 2J process, in addition to the above, the job title code and the department code can be compared with the code of the card 21 in real life.

If the information of the card 21 is valid in the 2K process, the information of the accessor and the access time, entry conditions, personal identification data, etc. are stored in the memory area of the control unit 24 in the 2H process.

At this time, the data stored in the memory area in the control unit 24 is also read by the PC 12 through the address discriminating unit 26 and the repeater 14 by the transfer request of the PC 12 and transmitted to the PC 12. The data are stored in a file and used for statistical calculation of various data in the future.

Meanwhile, the control unit 24 performing the process of FIG. 2M automatically discharges the IC card 21 inserted into the lead / light unit 20 in step 2N, and opens the door to the opening / closing unit 28 in step 20. ) Input the signal to open the door.

The control unit 24 which has opened the door in step 20 checks the door opening time in step 2P, and searches whether the predetermined time has elapsed in step 20.

If the predetermined time has not exceeded, the process jumps to the above-described process 2B and sets the state of the current door to the display unit of the opening / closing unit 28.

If the door opening time exceeds a predetermined time in 2Q, the controller 24 controls the buzzer 30 to ring in 2R. In addition, the state of the opening / closing unit 28 is read to find out whether the door is closed in step 2S.

If the door is not closed, the process 2R is performed, and if the door is closed, the process returns to the above-described process 2B and is performed as follows.

The main function of the PC 12 is to send the necessary data to the control unit 24 or to read the data from the control unit 24 to perform necessary status checks and statistical processing. Data transmission from the control unit to the PC 12 is performed when a data transmission request is received from the PC 12, and the PC 12 requests data transmission to the control unit 24 at regular time intervals. The main functions that can be performed in the PC 12 are as follows.

1) Preparation of entrance / exit status table: It shows the current entrance and exit status for a specific date and time, and it displays the operation status and the number of entrance and exit for each door.

2) Accident card processing: Incident card processing outputs a list of accident cards currently registered, and it is possible to add and delete an accident card. When the accident card is added and deleted, the above-described control section 24 interprets the meaning, and then the comparison section 22 adds and deletes the actual data.

3) Entrance and exit condition processing: Entrance and exit condition processing records the condition that only a person who has the authority to enter and exit the door can enter and exit the door in the comparator 24 of the controller. In this section, it executes the current condition of a specific statement, registers a new condition, and deletes an existing condition.

4) Statistical processing of the list of entering and leaving rooms: Outputs the access and time according to each door for a randomly designated date.

5) To control the access of all doors or a specific door, and to release the control.

6) When the door controller malfunctions or the data in the comparator 22 of the door controller is destroyed, the data can be transmitted to the specific door controller and the time of the PC 12 can be transmitted to the door controller to match the time. .

In addition, since the data transmitted from the PC 12 to the door controller is stored in the comparator 22 in the door controller, the controller can operate independently even when the PC 12 is not connected, and all the information controllers 24 for entry and exit are provided. The access data can be managed by the PC 12 by storing the data in its own storage location, and then automatically sending the data to the PC 12 at the request of the PC 12 when connecting to the PC 12 later.
