Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a distributed type entrance / exit management for centrally performing management and crime prevention notification of persons entering and exiting each entrance / exit of a building or the like by a central device. Regarding the system.

[Prior Art] In recent years, as the number of buildings rises, many tenants often live together in one building. In such a building, when entering each tenant's room,
Many locks are opened by inserting a key into the lock provided at the entrance, but with the intelligent construction of buildings and advanced security controls, the structure of such a lock and lock is shown in Fig. 12 instead. A system for unlocking an electric lock using such an ID card is used.

This system takes in the magnetic data recorded in the ID card 103 by inserting the ID card 103 in which magnetic data is recorded into the slit of the card reader 102 and sliding it, and the electrical data provided inside the card reader 102 is taken in. A lock control unit (not shown) determines whether the ID code matches a predetermined ID code, and when the ID codes match, the electric lock 101 attached to the door 100 is unlocked.

However, when installing such a system in a large number of tenants, as shown in FIG. 13, an electric lock (not shown) is attached to the entrance door 100 of each tenant, and a card is provided in the vicinity of each door. Since the reader 102 is installed, it is necessary to set an ID code for each card reader 102 for each tenant, which is very time-consuming.

Therefore, the applicant, in another patent application, transmits to each crime prevention terminal device having a card reader in the system after setting or deleting the data registered or deleted on the side of the center device, and thereafter transmits each crime prevention terminal device. We proposed a decentralized entry / exit management system that allows distributed operations on the side.

[Problems to be Solved by the Invention] However, in such a system, since the card reader 102 is used, it is necessary to create a system-specific card suitable for the card reader 102 and carry it with each person. So I had to carry around a specially created ID card, which was troublesome.

Therefore, in view of the above circumstances, the present applicant proposes the present invention, in which the central device provided in the building management room or the like collectively registers and deletes the ID code to be processed by each security terminal device. The object of the present invention is to provide a distributed access control system that allows existing ID cards to be used in the system.

[Means for Solving the Problems] The present invention proposed to achieve the above object is to read an ID code stored in a magnetic card or the like with an individually provided card reader, and read the read ID code. A plurality of security terminals with individually assigned addresses, which are designed to unlock electric locks only when they match with a pre-registered ID code, are connected to a central device via a multiple signal line. The ID code to be processed by each of the security terminals is individually registered and deleted on the side of the center device, and then transmitted to the memory section provided on the security terminal side. While performing distributed processing on each security terminal side in the system, on the security terminal side, the operating state is transmitted to the center device side,
In the decentralized access control system that enables centralized management on the side of the center device, existing ID cards such as employee cards, credit cards, bank cards,
It is configured to be used as it is, and in particular, the center device has a configuration in which the reading position on the card for reading the ID code stored in the ID card can be set according to each security terminal in the system. It is a thing.

In the system of the present invention described in claims 2 and 3, an automatic door opening / closing device and a key storage box are included as the crime prevention terminal device, and in the system described in claim 4, a crime prevention control panel provided with a crime prevention sensor is added. It has been configured.

[Operation] According to the system of the present invention, in any of the items proposed in the above, the reading position of the ID card can be changed and set on the side of the center device, so that the security terminal can simply read the existing ID card. Can be used in. Therefore, there are no restrictions on the cards that can be used, and it becomes easy to manage the cards.

Embodiment An embodiment of the system of the present invention will be described below with reference to the drawings.

FIG. 1 shows the basic configuration of an entry / exit management system to which the present invention is applied. In the figure, 1 is a center device installed in a building management room or the like for centralized control of the system, and 1 is a center. A multiple signal line derived from the device 1. The multiple signal line 1 includes a plurality of automatic door opening / closing devices A including a card reader 4, a card reader control panel 2 and an electric lock 5, and a key storage box. A security terminal having an individual address, such as the security key box 7 or the security control panel 3, is connected.

The details of these crime prevention terminal devices will be described later, but the automatic door opening / closing device A receives the ID code read from the ID card (not shown) by the card reader 4 connected to the card reader control panel 2 and stores the ID stored in advance. The security key box 7 is a device for determining whether the code matches with the code and unlocking the electric lock. The security key box 7 has a plurality of key boxes, and the built-in card reader unit stores in advance the ID code read from the ID card. It is a device that opens the corresponding key box after determining the match with the ID code. Further, when the security control panel 3 receives a detection signal from the connected security sensor 6, the security state set or stored in the security control panel 3 It is a device that transmits an alarm signal to the center device 1 in accordance with a warning release state.

In such a system, as will be described later, the center device 1 centrally manages the setting data of each crime prevention terminal device, and the data registered with these settings is transmitted to each crime prevention terminal via the multiple signal line l. Since it is configured to transmit the data to each security terminal and store the data for each security terminal, even if the center device 1 fails, control is performed for each security terminal based on the data stored in each security terminal. The system is capable of maintaining the operation, and all the operation data from each security terminal is transmitted to and recorded in the center device 1 while the center device 1 is in operation.

Further, it is possible to manually perform a specific door operation and an unlocking operation from the center device 1 and to automatically change and set the remote operation based on a preset schedule. ing.

The present invention is based on the data transmitted and stored from the center device 1 side to the crime prevention terminal device (the card reader control panel 2 of the automatic door opening / closing device A or the key storage box 7) in such a distributed type entrance / exit management system. The range of magnetic data recorded on the ID card read by the card reader 4 of the automatic door opening / closing device A or the card reader portion 7a of the security key box 7 can be arbitrarily set.

For example, FIG. 1a shows an ID card used in the system of the present invention, but in the magnetic data C1 recorded on an existing ID card such as an employee card, the employee required by the system is required. The existing card can be used by defining only the area E1 in which the code, the employee name, etc. are entered for each security terminal device on the side of the center device 1.

The ID code can be read by the card reader 4 of each security terminal.
Only the area E1 required when the I card is read by the (card reader unit 7a) may be limited, but the card reader 4
It is also possible to selectively use only the necessary data on the card reader control panel 2 (security key box 7) side after all the data C1 is read by the (card reader unit 7a).

Further, for a card that has already been used for another purpose, the ID code may be stored in a place that is not used and that position may be set as the reading position.

Therefore, in the system of the present invention, since the reading position of the ID card can be arbitrarily set, even if the existing ID card is used, it is not necessary to disclose all the card information related to the ID card, and it is possible to identify the ID card. All you have to do is to show me the data (the position where the ID code is stored). Therefore, private information is never exposed.

Further, when a card for other purposes such as a bill card is used together with the system of the present invention, there is an advantage that it can be used by storing identification data in an unused portion of the card information.

FIG. 2 shows the configuration of the center device 1, which is CP.
The bus line 1i derived mainly from U1a has an external storage device of a 5-inch floppy disk drive 1
b, a color CRT1c for displaying data or information on the screen,
A hard disk 1d as an external storage device for storing programs of this system, a keyboard 1e for inputting data, a printer 1f for printing out data and the like, and a clock 1g as an internal reference clock via respective interfaces. Connected by the bus line 1i
RS that converts parallel signals transmitted to
The 422 interface 1h is connected, and the multiple signal line 1 is derived from this RS422 interface 1h and connected to the above-mentioned many crime prevention terminal devices.

The communication method based on the RS422 standard is such that when data to be transmitted by the center device 1 or each terminal device is generated, a particular security terminal device or a specific security terminal device and the center device 1 are connected.
Data transmission is performed by establishing a data link with the security terminal, and each security terminal always receives and analyzes the signal on the multiple signal line l, and the data to which its own address is attached is transmitted to request transmission. If there is, send the data on the multiple signal line l,
When the answer has received the necessary data, it is set to immediately respond by the next communication.

FIG. 2A shows one frame of the multiplex signal transmitted on the multiplex signal line 1 according to the RS422 standard. Following the transmission start signal Tp, the address of the transmitting station side, the address of the receiving station side, the transmission data , A parity check bit P, and a transmission end signal Te.

3 (a) and 3 (b) are explanatory views showing the appearance of the card readers 4, 4'of the automatic door opening / closing device A used in the system of the present invention, and FIG. While receiving the data including the ID code to unlock the electric lock,
FIG. 3 is a block diagram showing an internal configuration of a card reader control panel 2 that returns a lock state signal to the card reader side. In the card reader 4 of FIG. 3 (a), the card insertion indicator lamp 4b lights up during standby to prompt the insertion of a card, and when an ID card (not shown) is inserted into the card insertion slit 4a and slid, the card reader 4 Data including the ID code recorded on the ID card is output to the control panel 2. Then, in the card reader control panel 2, the ID code from the card reader 4 and the memory section 2c of the card reader control panel 2 are stored in advance.
The CPU unit 2a determines whether the ID code (data set and transmitted on the side of the center device 1) matches, and when these ID codes match, outputs an unlocking permission signal to the electric lock control unit 2b, An unlocking signal is output from the electric lock control unit 2b to an electric lock (not shown) to perform unlocking control. Further, when the electric lock is unlocked, an unlock detection signal is transmitted from the electric lock to the card reader control panel 2, and the unlock detection signal is sent to the electric lock controller 2b and the CPU 2
The unlocking indicator light 4f of the card reader 4 is lit through a and. On the other hand, when the ID code is not normally read when the ID card is inserted into the card insertion slit 4a of the card reader 4, the card reader control panel 2 does not determine whether the ID code is coincident with the electric lock. The lock is not performed, and the card reinsertion indicator lamp 4c of the card reader 4 is turned on by the CPU 2a to prompt reinsertion.

The card reader 4'shown in FIG. 3 (b) has the same functions as the card reader 4 with respect to the card reader insertion slit 4a, the card insertion indicator light 4b, the card reinsertion indicator light 4c and the unlocking indicator light 4f. As will be done, the card reader 4'is further provided with a personal identification number input indicator 4d, a personal identification number re-entry indicator 4e and a ten-key 4g. By inputting a predetermined personal identification number (data set and transmitted on the side of the center device 1), the unlocking operation of the electric lock is performed.

In this system, when the electric lock is normally unlocked by the above procedure, or when the operation of reading the ID code of the ID card or the operation of inputting the personal identification number makes an error four times or more. The CPU 2a of the card reader control panel 2 discriminates and transmits card operation information of unlocking or error occurrence to the center device 1 side through the transmission unit 2d via the multiplex signal line l.

Further, in this system, in order to restrict access to a highly confidential room such as a computer room, the automatic door opening / closing device A provided at the entrance of such a room is installed in the card reader 4 (4 '). Only when the administrator inserts the ID card and the administrator inserts the ID card into a card reader (not shown) provided in the center device 1 and a coincidence determination signal of both ID codes is obtained, the center device 1 The electric lock is unlocked from the side.

In the present system, as will be described later, a mode in which the ID code is discriminated by the card reader control panel 2 itself based on the device type information transmitted from the center device 1 to the card reader control panel 2 of the automatic door opening / closing device A and the center. A mode that is performed by collating with the device 1, or a mode that is performed only by collating the ID code of the ID card when unlocking the electric lock,
After the ID code is collated, the mode for inputting the personal identification number by the ten keys can be switched and set from the side of the center device 1.

FIG. 5 (a) shows the external appearance of the security key box 7 which is a key storage box, and FIG. 5 (b) shows its internal structure in a block diagram. The security key box 7 includes a card reader section 7a and a plurality of key storage sections 7e (key box) ... The operation of the security key box 7 will be described with reference to the flowchart of FIG. In FIG. 6 (a), when the employee of the tenant comes to the office, if the ID card is inserted into the slit of the card reader 7a of the security key box 7 (step 1000), the ID code of the ID card is transmitted to the CPU 7b. When the ID code (data set and transmitted by the center device 1) stored in advance in the memory section 7c matches, the lid of the key storage section 7e corresponding to the ID code is opened (step 1001), By operating a key (not shown) inserted in an internal keyhole (not shown), the warning state of the entrance door of the tenant is released. Then, the key is removed, the lid of the key storage portion 7e is closed (steps 1002 and 1003), and the door of the company is unlocked with the key and the room is entered (steps 1004 and 100).
Five). That is, the control circuit section 7b and the transmission section 7d are operated by operating the key inside the key storage section 7e to put it in the warning release state.
Since the warning release signal is transmitted to the center device 1 via the multiple signal line 1 through the, the alarm is not output even when the door of the tenant is opened. Also, when the door of the tenant is opened, the door sensor 8 detects the door opening, and this door opening detection signal is the interface circuit 7f of the security key box 7.
Via the control circuit section 7b and the transmission section 7d.
The door opening information is also output to and recorded in the center device 1. On the other hand, as shown in FIG. 6 (b), when leaving the company, the entrance door of the company is locked with a key (step 100
6) Insert the card into the card reader 7a of the ID card security key box 7 and open the key box of the key storage 7e (steps 1007, 1008) Insert the key into the internal keyhole to change from the unwarned state to the vigilant state. After switching (step 1009)
By closing the key box (step 1010), the entrance door is set to the warning state again. Therefore, the employee only has to carry the ID card and does not need to carry the key, which makes it easy to manage the key.

FIG. 7 is a block diagram showing the internal structure of the crime prevention control panel 3. When a crime prevention sensor 6 such as a door opening sensor or a glass breakage detector attached to a door or a window issues a warning, this alarm is issued. Receive the signal from the sensor input section 3d
Data output to the CPU unit 3a and stored in the memory unit 3b in the CPU unit 3a (data set and transmitted by the center device 1)
After performing signal processing in accordance with the above, when it is necessary to output an alarm signal, the alarm signal is transmitted to the center device 1 through the transmission unit 3c through the multiple signal line l.

In the center device 1, as will be described later, it is possible to preset a warning state or a warning release state according to time, day, month, etc., and automatically set a schedule. Release it,
It is possible to finely set the security monitoring state by the security sensor 6, such as setting the alert state only at night.

FIG. 8 shows that when the CPU part of the security terminal such as the card reader control panel 2, the security control panel 3 or the security key box 7 of the automatic door opening / closing device A runs away due to an external factor, it interferes with the multiple signal line l. Watchdog timer 2e, which is a runaway detection means for outputting a signal to prevent the operation of other normal crime prevention terminals from being hindered
The circuit of FIG. As an example, a watchdog timer is provided on the card reader control panel 2 of the automatic door opening / closing device A.
The case where 2e is incorporated is explained. The CPU unit 2a outputs the pulse signal of a predetermined cycle set by the internal program to the output terminal OU
Outputs continuously from T1, watchdog timer
While this pulse signal is being input to the input terminal IN1 of 2e, the watchdog timer 2e is outputting a "H" level signal from the output terminal OUT2, so the relay RY of the line breaking means 2f is not driven, Therefore, its normally closed contact rya,
The ryb remains closed and normal multiplex signal transmission is performed. However, when the CPU section 2a of the card reader control panel 2 runs out of control for some reason, the CPU section 2a does not operate according to the program, so the pulse signal output of a predetermined cycle from the output terminal OUT1 is cut off, and the watch The output of the output terminal OUT2 of the dog timer 2e becomes "L" level, the relay RY is driven, the normally closed contacts rya and ryb are opened, and the card reader control panel 2 is disconnected from the multiple signal line l. The reliability of the system is improved by preventing interference with the crime prevention terminal and the center device 1.

Next, in the present system, as will be described later, by transmitting the device type information from the center device 1 to the card reader control panel 2 of the automatic door opening / closing device A, the ID code of the card reader 4 is sent to the center device 1 side. With the card reader control panel 2 or with the data stored in the card reader control panel 2 side (data set and transmitted by the center device 1) by the card reader control panel 2 itself, or with an ID card in the card reader 4. The person in charge can insert the ID card into another card reader installed in the control room, and control to unlock the electric lock only when the ID codes of both sides match. Is. Furthermore,
By setting the schedule on the center device 1 side,
Depending on the time of day, the electric lock can be unlocked only by operating the ID card, or the electric lock can be unlocked when the password is entered using the numeric keypad in addition to operating the ID card. The switching setting can be automatically performed.

FIG. 9 shows a restoration for automatically reading data related to the security terminal from the center apparatus 1 after repairing the security terminal when the security terminal such as the automatic door opening / closing device A fails. This is an explanation of how to use the card. For example, when the card reader control panel 2 breaks down and the power supply is cut off, all the data such as the ID code and the set secret code stored in the internal memory unit 2c will be lost. After the failure of the reader 2 is repaired, it is necessary to sequentially send out all the data regarding the security terminal device from the center device 1 side, which is very time-consuming. However, if the data recovery card SC of this system is used, it can be used as a card reader 4 provided on the side of the card reader control panel 2 that has repaired the failure (the same applies to the card reader unit 7a provided on the security key box 7). By simply inserting the data recovery card SC, the data acquisition work for the card reader control panel 2 in which a failure has occurred is automatically performed, so even if you do not understand the contents of the system, it is easy to do before the failure. It is possible to restore the state of.

Next, the functions performed by the program on the side of the center device 1 will be sequentially described with reference to the display contents of the CRT screen of the center device 1.

FIG. 10 shows the menu structure displayed on the color CRT 1c by the program when the center device 1 is operated. As shown in FIG. 10, all system operations are performed on the initial menu screen (see FIG. 11). (See FIG. 11), any one of a plurality of main menus M1 to M9 displayed on the screen is selected, and necessary operations are performed according to the screens (FIGS. 11a to 11i) of the selected main menu.

These main menus are the alarm / status display menu M1 (see FIG. 11a) that sequentially displays alarm information and status changes that occurred during system operation, the card reader 4 of the automatic door opening / closing device A, or the security key box 7. A door status display menu M2 (see FIG. 11b) that displays a list of door opening / closing statuses and door opening / closing history by the card reader unit 7a,
Registration menu M3 (see FIG. 11c) for newly setting and registering card information, security terminal information, etc., Search menu M4 for searching and displaying data such as card information, security terminal information or alarm status (see FIG. 11d) , Remote operation menu to unlock each door from the center device 1 by remote operation
M5 (see Fig. 11e), data storage menu M6 (see Fig. 11f) for storing card information and security device information in an external storage device (such as floppy disk), printer card information and security device information A data print menu M7 (see Fig. 11g) to be printed by, a system data registration menu M8 (see Fig. 11h) for setting weekly, yearly, daily change schedules, etc., and an end menu for terminating the system program are provided. There is.
In addition to these 9 main menus, a terminal device information registration menu M9, which is not displayed on the initial menu screen, is for registering information on security terminals during system treatment.
(See FIG. 11i) is displayed by a specific key operation.

Further, at the bottom of the CRT screen of the center device 1, a comment display area for prompting an input by an interactive operation and a function key contents display area of a computer keyboard are provided.

The main operation procedure of the program of this system will be described below with reference to the screen of the main menu.

(1) Terminal device information registration menu When the initial menu (see FIG. 11) is displayed, if a specific key that is set in advance is input,
The terminal device information registration screen shown in Fig. i is displayed, and the address, type (security key box 7, security control panel 3 or card reader 4 distinction), and operation type (numeric keypad operation) of the security terminal device to be registered are displayed. Presence / absence, distinction between ID code local verification or center verification) and PIN code type (no PIN code, by card, by terminal device) are sequentially entered to set the information of the security terminal device, and finally registered by confirmation. Be done. The security terminal information registered in this manner is used as basic data for the control operation of the subsequent system.

(2) Registration menu When "3. Registration" is selected in the initial menu (see Fig. 11), the registration menu screen shown in Fig. 11c is displayed. From this registration menu, select the item to register from ID card information, card reader information, security key box or schedule data,

Is performed. Also,
The automatic door opening / closing device A or the security key box 7 displays data such as the ID code C1 of the used ID card and the card user name C2. Therefore, by tracing back the displayed data, the operational status of the crime prevention terminal, the usage status of the card, the occurrence status of troubles, etc. can be found out one by one, so it is possible to perform detailed entry / exit management as well as maintenance or failure. It is useful as data at the time of occurrence. It should be noted that the data such as the alarms, the states, etc., which are displayed on the screen before and are generated, are displayed by a search menu described later.

(5) Door status display menu When "2. Door status display" is selected in the initial menu (see Fig. 11), the screen switches to the screen shown in Fig. 11b, and the doors where each card reader or security key box is installed are displayed. Information such as the open / close state and the history of the open / close operation is displayed in a list.

(6) Remote operation menu Select "5. Remote operation" from the initial menu (see Figure 11) to switch to the remote operation screen shown in Figure 11d.
From the side of the center device 1, it is possible to unlock the electric lock of the door provided in each part. This operation is an automatic door opening / closing device A provided on the door that is going to be remotely operated.
Or enter the terminal address TA of the security key box 7 and enter the terminal address T of the corresponding terminal.

(7) Search menu When "4. Search" is selected in the initial menu (see Fig. 11), the search menu shown in Fig. 11d is displayed, and information on the used card, card ID code, etc. It is possible to search and display data such as information, the name of the terminal device, and the alarm status that occurred. For example, if you want to display the alarm and status history for each security terminal or for all security terminals, select "6. Alarm / status data" in the search menu in Fig. 11d to enter the address of the security terminal. By switching to, and inputting an address according to the instruction, the history of alarms and states of the crime prevention terminal is displayed retroactively.

Further, it is possible to print the display screen on the printer by operating the print key (not shown) while the alarm / state history is displayed on the screen. Similarly, data that can be searched by this search menu can be printed out by a printer as needed.

(8) Data save menu When "6. Save data" is selected in the initial menu (see Fig. 11), the data save menu shown in 11f is displayed, and card information, terminal information, alarm / status data or card information is displayed. Data such as operation data can be stored in an external storage device (such as a floppy disk). When this system is in operation, status signals from each security terminal are always transmitted to the center device 1. By storing these data in an external storage device, it is possible to perform maintenance at the time of failure or maintenance. Will be reference data. Therefore, for example, if you select "4. Card operation data" in this data save menu, you can switch to the setting screen for specifying the period for saving, and save the card operation data for the specified period to a floppy disk, etc. Transferred and saved.

(9) Data print menu When "7. Data print" is selected in the initial menu (see Fig. 11), the data print menu shown in Fig. 11g is displayed, and the card data and terminal data are printed out by the printer. It is possible.

Therefore, if the card data or the terminal device data is printed out every predetermined period, it becomes useful data when a failure occurs or during maintenance.

As described above, in the system of the present invention, by using such a system program, the operation setting of the card reader and the card reader control panel provided in each security terminal can be centrally performed on the side of the center device. Therefore, it is possible to use an existing card without using a system-specific ID card. In addition, registration setting of data of each crime prevention terminal, deletion, data search, printing,
Since various operations such as saving and setting schedules are guided by the interactive form with the computer screen, it is possible to easily perform them, and at the same time, the central device 1 collects a large number of distributed security terminal information at once. Since it is managed in a distributed manner, it is possible to easily set and change data despite the distributed system.

[Effect of the Invention] According to the present invention, it is possible to provide a decentralized access control system in which existing ID cards such as employee cards, credit cards, and bank cards can be used without using an ID card dedicated to the system. It is easy to manage cards without the hassle of carrying many cards.

Further, since the reading position of the ID card can be arbitrarily set from the center device side, when using an existing ID card, it is not necessary to disclose all card information regarding the ID card. Therefore, it is only necessary to show the data to be identified (the position where the ID code is stored), and the private information is kept secret.

Further, when a card for other purposes such as a bill card is also used, there is an advantage that it can be used by storing identification data in an unused portion of the card information.
