Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides distributed entry/exit management for centrally performing the management of persons entering and exiting each entrance of a building, etc., and crime prevention notifications using a central device. system.

[Prior Art] Recently, as buildings have become taller, there are many cases where a large number of tenants live together in one building.In such buildings, when entering each tenant's room, it is necessary to In many cases, the lock is unlocked by inserting a key into the provided lock, but as buildings become more intelligent and security controls become more sophisticated, this type of key and lock configuration is replaced by the one shown in Figure 12. A system is used in which an electric lock is unlocked using an ID card.

This system takes in the magnetic data recorded on the ID card ID3 by inserting the ID card ID3 with magnetic data recorded into the slit of the card reader ID2 and sliding it. ID predetermined by the lock control unit (not shown)
It is determined if the ID codes match, and when these ID codes match, the electric lock ID1 attached to the door ID0 is unlocked.

However, when installing such a system to a large number of tenants, as shown in FIG. Since the configuration is to install reader ID2, it is necessary to install card reader ID2 for each tenant.
It was necessary to set an ID code, which required a great deal of effort.

Therefore, in another patent application, the present applicant has set and transmitted data registered or deleted on the center device side to each security terminal device with a card reader in the system, and after that, each security terminal device We proposed a distributed entry/exit control system that can be operated in a distributed manner.

[Problems to be Solved by the Invention] However, in such a system, since the card reader ID2 is used, the card reader ID
Since it was necessary to create a system-specific card compatible with 2 and carry it with each person, it was troublesome to have to carry around a specially created dedicated [D card].

Therefore, in view of the above circumstances, the present applicant proposes the present invention, in which the registration and deletion of ID codes to be processed for each security terminal device are carried out in a central device installed in a building management room, etc. The present invention is an improvement of a decentralized person access control system, in which an existing ID card can be used in the system.

[Means for Solving the Problems] In order to achieve the above object, the present invention proposed by L4 reads an ID code stored in a magnetic card or the like with a card reader provided individually, and reads the read ID code. Multiple security terminals with individually assigned addresses are connected to a central center via multiple signal lines, such as unlocking electric locks, etc., only when the ID code matches a pre-registered ID code. By individually registering and deleting ID codes connected to the device and processed by each of the security terminals on the center device side, and then transmitting them to the memory section provided on the security terminal side. , the individual security terminals in the system perform distributed processing, and the security terminals transmit their operating status to the center device. ll! In a decentralized traffic conduit system that can be centrally managed using an ID card, in particular, on the central equipment side, the reading position on the card to read the ID code stored in the ID card is set to the security terminal device in the system. It has a configuration that can be set according to each.

Furthermore, the distributed entry/exit management system according to claim 2 is configured to use an existing ID card, such as an employee card, as is.

In the system of the present invention described in claim 3.4, the security terminal device includes an automatic door opening/closing device and a key storage box, and in the system described in claim 5, a security control panel equipped with a security sensor is added. The configuration is as follows.

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

[Embodiment 191] 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 the entrance/exit control system to which the present invention is applied. This is a multiple signal line derived from the device 1, and this multiple signal line 1 is connected to an automatic door opening/closing device A of fJI number consisting of a card reader 4, a cart reader control panel 2, and an electric lock 5, and a key storage box. A security terminal device such as a certain security key box 7 or security control panel 3 having an individual address is connected.

Details of these security terminals will be described later, but the automatic door opening/closing device A is controlled by a card reader #! The card reader 4 connected to the security key box 12 receives an ID code read from an ID card (not shown), determines whether the code matches a pre-stored ID code, and unlocks the electric lock. 7 is equipped with a key box with 11 losses, and the built-in card reader section reads the ID from the ID card.
This is a device that determines if the D code matches a pre-stored II) code and opens the corresponding key box. Also, when the security control panel 3 receives a detection signal from the connected security sensor 6, This is a device that transmits an alarm signal to the center device 1 according to a set and stored alert state or alert release state.

In such a system, as will be described later, the setting data of each security terminal is centrally managed in the center device ll, and the registered setting data is sent to each security terminal via a multiplex signal line j. Since the configuration is such that the data is transmitted to the device and stored in each security terminal @'iB, even if the center device fails, data can be transmitted to each security terminal based on the data stored in each security terminal. The system is such that it is possible to maintain control operations, and all operation data from each security terminal is transmitted to the center device 1 and recorded while the center H11 is in operation.

In addition, it is possible to manually lock and unlock a specific prisoner remotely from the center device 1, and it is also possible to automatically change and set this remote control based on a preset schedule. ing.

In such a distributed entry/exit control system, the present invention provides data that is transmitted from the center device 1 to the security terminals (card reader control panel 2 and key storage box 7 of the automatic gate lock A) and stored therein. Based on this, 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 section 7a of the security key box 7 can be set arbitrarily and variably.

For example, FIG. 1a shows an ID card used in the system of the present invention, but among the magnetic data C1 recorded on an existing ID card such as an employee card, the Only the area El in which the code, employee name, etc.
By specifying this for each security terminal in step 1, it becomes possible to use the existing card tt.

To read the ID code, use the card reader 4 (
Although it is possible to limit only the necessary area El when reading the ID card with the card reader 17a), after reading all the data CI with the card reader 4 (card reader section 7a), the card reader control panel 2 (security Key box?) It is also possible to selectively use only the necessary data in full.

Furthermore, for a card that has already been used for another purpose, the ID code may be stored in an unused location and that location may be set as the reading location.

Therefore, in the system of the present invention, the reading position of the ID card can be set arbitrarily, so even when using an existing ID card, there is no need to disclose all the card information on the ID card. , it is only necessary to have the user show the data to be identified (the location where the ID code is stored), so private information will not be exposed.

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

Figure 2 shows the configuration of the center device l.
The path line li derived around U1a stores a 5-inch floppy disk drive 1b as an external storage device, a color CRT 1c for displaying data and information on the screen, and the program of this system. A hard disk drive 1d as an external storage device for data processing, a keyboard 1e for manually inputting data, a printer 1f for printing data, etc., and a clock 1g as an internal reference clock are connected via their respective interfaces. , an R3422 interface 1h for converting parallel signals transmitted to the path line 11 into serial signals is connected, and a multiplex signal line 1 is led out from this R5422 interface 1h and connected to the numerous security terminals mentioned above. ing.

The communication method based on this R5422 standard is
i! Alternatively, when data to be transmitted from each terminal is generated, a data link is established between specific security terminals or between the security terminal and the center device 1 to transmit the data. The device receives and analyzes the signal on the multiplex signal line l in the palm of its hand, and if data with its own address is sent and there is a send Ig request, it sends the data on the multiplex signal line l, and if an answer is required. When data is received, the system immediately responds with the next communication.

FIG. 2A shows an l frame of a multiplexed signal transmitted on a multi-il signal line l according to the R5422 standard. Following the transmission start signal Tp, the address of the transmitting station, the address of the receiving station, and the transmission The configuration includes data, a parity check bit P, and a transmission end signal Te.

FIGS. 3(a) and 3(b) are explanatory diagrams showing the appearance of the card reader 4゜4' of the automatic door opening/closing device A used in the system of the present invention, and FIG. I
This is a block diagram showing the internal configuration of a card reader control panel 2 that receives data including a D code, unlocks an electric lock, and sends a key status signal back to the card reader side. In the card reader 4 of FIG. 3(a), when on standby, the cart insertion indicator light 4b lights up to prompt card insertion, and when an ID card (not shown) is inserted into the card insertion slit 4a and slid, the cart reader Data including the ID code recorded on the ID card is output to the control panel 2. Then, in the cart reader control panel 2, the ID code from the card reader 4 and the ID code stored in advance in the memory section 2C of the card reader control 41!2 (center device l
020 part 2 (data set and transmitted on the side)
If these ID codes match, an unlock permission signal is output to the electric lock control unit 2b, and an unlock signal is output from the electric lock control unit 2b to an electric lock (not shown) to unlock it. When the electric lock is unlocked, an unlock detection signal is sent back from the electric lock to the card reader control panel 2, and this unlock detection signal is transmitted to the card reader through the electric lock control section 2b and the 020 section 2a. 4, the unlock indicator light 4f is turned on.

On the other hand, if the ID code cannot be read normally when the ID card is inserted into the card insertion slot 4a of the card reader 4, the card reader control panel 2 will not check if the ID code matches, so the electric lock will The card is not unlocked, and the card reinsertion indicator light 4c of the card reader 4 is turned on by the 020 section 2a to prompt reinsertion.

The card reader 4' shown in FIG. 3(b) has the same functions as the card reader 4 regarding the card reader insertion slit 4a, card insertion indicator light 4b, cart reinsertion indicator light 4c, and unlock indicator light 4f. However, this card reader 4' is further equipped with a password input indicator light 4d, a password re-input indicator light 4e, and a numeric keypad 4g, and after the ID code of the ID card is determined to match, the card reader 4' 1 by entering a predetermined password (data set and transmitted at center device 1 (11)).
One lock is to be unlocked.

In addition, in this system, if the electric lock is successfully unlocked according to the above procedure, or if either the operation of reading the ID code of the ID card or inputting the PIN number fails four or more times, , is determined by the CPU section 2a of the card reader control panel 2, and the multiplexed signal &! is determined through the transmission section 2d. Card operation information indicating unlocking or error occurrence is transmitted to the center device 1 via l.

In addition, in this system, in order to restrict access to mine-prone rooms such as computer rooms, the automatic 1 opening/closing device A installed in the population of such rooms is equipped with a card reader 4.
(4'), and the administrator also inserts the ID card into a card reader (not shown) provided in the center device 1, and only when a match determination signal of both ID codes is obtained. The electric lock is unlocked from the center unit a194.

In addition, in this system, as described later, the center device l
Depending on the device type information transmitted from the card reader control panel 2 to the automatic door opening/closing device, there is a mode in which the ID code is determined by the card reader control panel 2 itself, a mote in which ID code is determined by checking with the center installation fil, or an electric lock. When unlocking, it is possible to switch from the center device 1 side to a mode in which only the ID code of the ID card is verified, or a mode in which a password is further input using the numeric keypad after the ID code is verified.

FIG. 5(a) shows the external appearance of the security key box 7, which is a key storage box, and FIG.
) is a block diagram showing its internal configuration. This security key box 7 has a card reader section 7.
& and a plurality of key storage sections 7e (ll boxes) and φ numbers, and its operation will be explained with reference to the flowchart in FIG. In FIG. 6(a), when an employee of the tenant comes to work, when he inserts his ID card into the slit of the card reader section 7a of the security key box 7 (step ID00), the ID code of the ID card is C.
When the ID code transmitted to the PU section 7b and matched with the ID code stored in advance in the memory section 7c (data set and transmitted in the center device 1), the lid of the key storage section 7e corresponding to the ID code is opened. (Step ID01),
Key (not shown) inserted into the internal keyhole (not shown)
Operate to release the alert status of the tenant's entrance door.

Then, remove the hammer and close the lid of the key storage part 7e (
Step ID02. ID03), unlock the company's gate by its casting and enter the room (step ID04.ID05)
), that is, by operating the key inside the key storage section 7e to release the alarm, the center unit ff is activated via the control circuit section 7b and the transmission section 7d, via the multiplex signal line
Since the warning M exclusion signal is transmitted to 1l, no alarm is output even if the tenant's shield is checked.Also, when the tenant opens the door, the door sensor 8 detects that the door is opened, and this door opening detection signal is sent to the security key. It is output to the multiplex signal line l via the interface circuit 7f of the box 7, the control circuit section 7b, and the transmission section 7d, and is similarly output to the center device l.
Door opening information is output and recorded to l. On the other hand, Fig. 6 (b
), when leaving the office, lock the company's entrance door with the bell (step ID06), insert the ID card into the card reader section 7a of the security key box 7, and open the key box in the key storage section 7e (step ID06). ID07° ID08) After inserting the key into the internal keyhole to switch from the guard release state to the guard state (step 1OO9) and closing the key box (suite ID ID), the entrance door is set to the guard state again.

Therefore, the employee only needs to carry the ID card and does not need to carry the key, making it easier to manage the key.

Figure 7 shows the internal configuration of the security control panel 3 using a block diagram. The sensor human power section 3d receives the signal and turns 0.
20 section 3a, and the CPU section 3 & performs signal processing according to the data stored in the memory section 3b (data set and transmitted by the center device 1), and then when it is necessary to output an alarm signal, the transmission section 3c and transmits the alarm signal to the center device l via the multiplex signal line l.

In addition, as will be described later, in Center 1iffil, it is possible to set a schedule in which the alarm state or alarm state is automatically switched by setting the alarm state or alarm state in advance according to the time, day, month, etc. It is possible to set the security monitoring state by the crime prevention sensor 6 in detail by setting the security monitoring state to the security state only before night.

Figure 8 shows the card reader system i1!1 of automatic gate closing device A.
2. When the CPU section of a security terminal such as the security control panel 3 or the security key box 7 goes out of control due to an external factor, it outputs an interference signal to the multiplex signal line l to prevent other security terminals from operating normally. This figure shows a circuit of a watchdog timer 2e, which is a runaway detection means for preventing trouble. - As an example, a case will be explained in which a watchdog timer 2e is incorporated into the card reader control panel 2 of the automatic door opening/closing device A. The CPU section 2a continuously outputs a pulse signal with a predetermined cycle set by the internal program from the output terminal 0UTI, and during the period when this pulse signal is manually input to the input terminal INI of the watchdog timer 2e, the watchdog timer 2e is activated. Since the timer 2e is outputting an "H" level signal from the output terminal 0UT2, the relay RY of the line cutoff means 2f is not driven, so its normally closed contacts rya and ryb remain closed, and the normal multiplex A signal is transmitted. However, if the CPU section 2a of the card reader control panel 2 goes out of control for some reason, the CPU section 2a will no longer operate according to the program, and the pulse signal output at a predetermined period from the output terminal OUT 1 will be cut off. When the output of the output terminal 0UT2 of the watchdog timer 2e becomes rLJ level, the relay RY is driven, and the normally closed contacts rya and ryb are closed and the card reader control 112 is disconnected from the multiplex signal line 2. This improves system reliability by preventing interference with terminals and center equipment.

Next, in this system, as described later, the center device
By transmitting device type information from the device to the card reader control panel 2 of the automatic door opening/closing device A, the ID code of the card reader 4 can be verified with the center device 1 (11),
Alternatively, the card reader control panel 2 can check the data stored in the card reader control panel 2 itself (data set and transmitted by the center device), or the ID card can be inserted into the card reader 4 and the management room A person in charge can insert an ID card into a separate card reader installed in a separate card reader, and control the electric lock to be unlocked only when both ID codes match. Furthermore, by setting a schedule on the center device side, electric locks can be unlocked only by operating the ID card depending on the time of day, or [in addition to operating the D card, manual access to the PIN code using the numeric keypad] It is said that it is possible to automatically perform a switching setting such that the electric lock is unlocked when the user performs the following steps.

FIG. 9 shows how to automatically read data from the center device 1 to the security terminal after repairing the security terminal when the security terminal such as the automatic +1 opening/closing device A malfunctions. The following is an explanation of how to use the recovery card. For example, if the card reader control panel 2 malfunctions and the power supply is cut off, all data stored in the internal memory section 2c, such as the D code and set PIN number, will be lost. After the failure of the card reader 2 is repaired, it is necessary to sequentially send out all the data stored in the security terminal from the center device 1fl, which requires a lot of effort. However, if you use the data recovery card SC of this system, the card reader 4 (
By simply inserting the data recovery card SC into the card reader section 7a provided in the security key box 7, the work of importing data from the failed card reader control panel 2 is automatically performed. Therefore, even someone who does not understand the contents of the system can easily restore it to the state before the failure.

Next, the functions performed by the program of one example of the center device will be explained in order while referring to the display contents of the CRT screen of the center device 1.

11! The ID diagram is used when operating the center device 1.
This figure shows the menu structure displayed on the color CRT1c by the program.As shown in the figure, all system operations can be performed using one of the multiple main menus M1 to M9 displayed on the initial menu screen (see Figure 11). 11a to 11i) and perform necessary operations according to the selected main menu screen (FIGS. 11a to 11i).

These main menus are the alarm/status display menu that sequentially displays alarm information and status changes that occur while the system is operating. - Door status display menu M2 (11th bl! In! light) that displays a list of door opening/closing status and door opening/closing history using the key box 70 card reader unit 7a, new settings and registration of card information, security terminal information, etc. Registration menu M3 (see Figure 11c) to search for and display data such as card information, security terminal information or alarm status

il), data storage menu M6 (see Figure 11) for storing card information, security terminal information, etc. in an external storage device (floppy disk, etc.), and data for printing card information and security terminal information with a printer. There are provided a print menu M7 (see FIG. 11), a system data registration menu M8 (see FIG. 11h) for setting a schedule that changes every nine years twice a week, etc., and an exit menu for ending the system program. In addition to these nine main menus, there is also a terminal information registration menu M9 (not displayed on the initial menu screen) for registering security terminal information during system installation.
31E11i (Fig. 11w1) is displayed by operating a specific key.

Further, at the bottom of the CR7 screen of the center device 1, there are provided a comment display area for encouraging human effort through interactive operations and a function key content display area for the computer keyboard.

The main operating procedures of the program of this system will be explained below with reference to the main menu screen.

(1) When the terminal device information registration menu initial menu (see Figure 11) is displayed, if you input a specific predetermined key,
The terminal device information registration screen shown in Figure i is displayed, and the address, type (security key box 7, security system W panel a, or card reader 4), and operation type (numeric keypad operation) of the security terminal device to be registered are displayed. presence or absence, +D code local verification or center verification), PIN code type (no PIN code, by card, by terminal date)
The information on the security terminal is manually set in sequence, and the registration is completed through confirmation at the end. The security terminal information registered in this manner is used as basic data for subsequent control operations of the system.

(2) If you select "3° Climb" in the registration menu initial menu (No. 11 @ Reference page!!), the registration menu screen shown in Figure 11c will be displayed. From this registration menu, ID card information will be displayed. , card reader information, security key box, or schedule data, and the registration operation is performed interactively.

For example, r4. When schedule data 1 is selected,
The screen switches to an operation instruction screen, where registration is done in an interactive format, and card reader control panels with a numeric keypad are connected to electric locks at all times during the day, from 6 p.m. to 12 p.m. Until then, the electric lock can be unlocked only by operating the card reader, and from midnight to 9 a.m. the next day, the electric lock can be unlocked by operating the card reader and entering a PIN number using the numeric keypad. Several types of predetermined schedules are set.

In this way, when the data registration of each security terminal device is completed in the center device 1, select r5 in the registration menu. By selecting Registration Complete (Send to Terminal) 1, the registered data will be transmitted to each security terminal and stored.
Thereafter, control is performed based on the stored data on each security terminal side.

Therefore, even if the center device 1 breaks down while the system is in operation, each security terminal side will
It is possible to perform operations according to the data transmitted and stored from the computer. In addition, since the setting data for each security terminal is centrally managed on the central device side, even if a large number of security terminals are installed in separate locations, the settings are easy and there is no risk of confusion. It disappears.

(3) If you select r8゜System Data Registration 1 in the initial menu of the system data registration menu (see #1 in Figure 11), one of the schedule data set in the registration menu for the security terminal will be displayed.
The screen changes to a screen for selecting and setting the type of daily operation schedule, and following the instructions, set the schedule type for each day.

In other words, by setting in advance the operation schedule of the security terminal for each day of a week or month, the monitoring schedule of the security terminal described above is automatically switched and set, so that detailed monitoring can be performed. Can be done.

(4) Alarm/Status Display Menu If you select "1゜Alarm/Status Display 1" in the initial menu (see No. 111!l), the screen will change to the one shown in Figure 11a, displaying the operating status of each security terminal and the alarm output. Displays a list of the status and failure status.

The displayed data includes the date and time of the operation, the security terminal address TA, the security terminal name TN, and the type and data of the state that occurred next, with the latest data displayed in sequence at the top of the screen. will be carried out.

In addition, the ID code CI of the ID card used in automatic gate closing V device A or security key box 7 is
Data such as the cart user name C2 and the like are displayed. Therefore, if you trace back the displayed data, you will be able to find out the operational status of the security terminal, card usage status, trouble occurrence status, etc., making it possible to perform fine-grained crowd control, and also to monitor the situation during maintenance. This is useful as data when a failure occurs. Note that data such as previously generated alarms and conditions displayed on the screen can be displayed using a search menu to be described later.

(5) Door status display menu Selecting "2° door status display" in the initial menu (see #1 in Figure 11) switches to the screen shown in Figure 11b, and displays the screen where each card reader or security key box is installed. Information such as the opening/closing status of the prisoner and the history of opening/closing operations is displayed in a list.

(6) From the remote control menu initial menu (see Figure 11), select r5. When remote control 1 is selected, the screen switches to the remote control screen shown in FIG. 1 ID, and it is possible to unlock the electric shoulder locks provided at each part from the center device I side. This operation is performed by manually inputting the terminal address TA of the automatic prisoner closing device A or the security key box 7 mounted on the shield to be remotely controlled, then the terminal address TA of the corresponding terminal, terminal Since the three aTNs and the current status are displayed, control is performed by performing a confirmation operation after inputting the operation type (locked, unlocked, etc.).

(7) Search menu If you select r4゜Search 1 in the initial menu (see Figure 11), the search menu shown in Figure 1 ID will be displayed, and information such as information on the card being used and the ID code of the card will be displayed. It is possible to search and display data such as the name of the terminal and the alarm status that has occurred.0For example, when displaying the history of alarms and status of the security terminal or all security terminals, In the search menu of Figure 1id, r6. When alarm/status data j is selected, the screen changes to an input screen for the address of the security terminal, and by manually inputting the address according to the instructions, the history of alarms/status of that security terminal is displayed retrospectively.

Further, when a print key (not shown) is operated while the alarm/state history is displayed on the screen in this way, it is possible to print out the displayed screen on a printer.

Similarly, data that can be searched using this search menu can be printed out using a printer if necessary.

(8) Data save menu If you select “6゜Data save 1” in the initial menu (see Figure 11), the data save menu shown in 11f will be displayed, and the card information, terminal device information, alarm/status data or card information will be displayed. Data such as operational data can be stored in an external storage device (such as a floppy disk).

When this system is in operation, the security signals from each security terminal are constantly being transmitted to the center unit, and by storing this data in an external storage device, it can be used in the event of a failure or This will serve as reference data during maintenance. Therefore, in this data save menu, for example, r

Therefore, if card data or terminal device data is printed out at predetermined intervals, the data will be useful 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 settings of the card reader and card reader control panel provided in each security terminal can be centrally performed on the central device side. Therefore, it is possible to use an existing cart without using a system-specific ID card. In addition, you can register, delete, and search data for each security terminal, print data,
A wide variety of operations such as saving and setting schedules are guided through interaction with the computer screen, making them easy to perform.At the same time, information from a large number of distributed security terminals can be collected at once from a central device. Even though it is a distributed system, data settings and changes can be easily performed.

[Effects of the Invention] According to the present invention, it is possible to provide a distributed entry/exit management system in which an existing ID card can be used without using a system-specific ID card, so there is no need to carry around many cards. Card management is easy.

In addition, since the reading position of the ID card can be set arbitrarily, when using an existing ID card, there is no need to disclose all the card information on the ID card. All you need to do is show the data (the location where the ID code is stored), and your private information will be kept secret.

Furthermore, when using cards for other purposes such as bill cards,
Another advantage is that it can also be used by storing identification data in unused portions of card information.
