Description

DETAILED DESCRIPTION OF THE INVENTION In a security system, the present invention allows the security identification code and T9 key code to be registered and changed, that is, re-registered, with a simple operation even at the site where the system is installed. This invention relates to a key code registration system for use with high security.

Conventionally, for setting the security mode of the security system or setting the key code for changing the security mode, a well-known ROM is used as an element to store the key code, and the same ROM is used.
A key code is set on the M using a special device, that is, a ROM writing device, and the same ROM is installed in the controller or reader in the security system, and the same code as the set key code is input on a card, etc. When configured via a medium,
A configuration is adopted that makes it difficult to set or change the security mode.

This is especially because the key code already set in the ROM will not be erased even if the power is cut off when the security system is in use.

Moreover, it is widely adopted from the viewpoint that the security system has a higher degree of security and is easier to manage if the initial set key code cannot be changed during the process. The usage pattern is as follows:
This uses a medium, such as a card, in which the same code is stored in correspondence with the key code stored in the OM.

In this way, conventional key code settings in security systems do not assume changes, and in order to maintain a high level of security, key codes are set at a location such as a security center. However, In recent years, this type of security system has become widely adopted, and the key code of the controller and reader installed in the system and the key code of the card that is the input medium are used in the security system. An inconvenient situation has arisen in which υ does not match due to a mistake during shipping to the installation site or during installation, and if the card is lost, the key code must be changed. In addition to reissuing the ROM, we will also be reissuing the ROM and the ROM with a different key code set for security reasons.
It is necessary to change the card to one that is compatible with the above, which is complicated, and also increases maintenance costs.

Furthermore, when a ROM is used, there is a disadvantage that if the memory contents are intentionally erased with a magnet or the like, it cannot be reused and must be discarded. On the other hand, there is also a conventional method of setting a key code using a switch means without using a portable input medium such as a card.
In this method, for example, a rotary switch is used, and when the rotary switch is set to the desired position, a loop state is formed, and the loop 7? A current flows through the system, operating a relay, or depending on the presence or absence of current, the mode of the security system or the access control system is set to allow or deny access. That is, in this case, the circuit is configured so that when a predetermined key code is set by the switch means, a loop state is formed as described above. However, in this method, the key code is usually a combination of directrix numbers, so it is necessary to set the numbers repeatedly.
There is a problem in that the security accuracy of security is low because the code setting that becomes FU is accidentally ignored. And something like this
According to the #Number Code, in the event of an unforeseen situation such as when a person in charge of security system preparation is under duress, the key code and knob combination number numbers must be changed. There is a drawback that key code settings can be made by anyone other than the user. Furthermore, there was a problem in managing the key code, as it had to be written on the device so that it could be operated even if the key code was forgotten.

The present invention has been proposed to solve the above-mentioned problems, and its purpose is to make it possible to easily change the key code and register it even at the site where the system is installed. To provide a security key code registration system with a high degree of security, which prevents anyone other than an authorized person from changing or registering the key code. According to the present invention, registration setting of a security key code of a security system;
To make the change settings, the condition determining means determines whether the key code inputted by the input means for inputting the key code from the input medium on which the key code is recorded matches or does not match the predetermined condition. , a storage means for registering and storing the 'lf reserve identification code in the key code on the input medium when the condition determination means determines a match; and a storage means for reading the security identification code registered in the storage means and from the input medium. A security key code registration system that is equipped with a verification means provided to perform comparison and verification with a key code that is arbitrarily input, and that enables registration settings or change settings of security key codes at the site. is provided. Hereinafter, all embodiments of the present invention will be explained in detail.

FIG. 1 is a block diagram showing an embodiment of a security key code registration system according to the present invention.

In the same Figure 1, 1 is an input means for registering the key code and setting or changing the security mode, and 2 is normally connected to the verification circuit 8 described later, when registering the key code in the input medium A. A setting switch 3, which is a switching means for switching to the registration unit 7, is a condition determination circuit 8, which determines whether or not a predetermined condition matches the condition of the key code input from the input means 1. Once the key code has been registered and the Fcbebe mode setting and the security mode change setting have been performed, the key code is checked against the key code registered in the registration section 7, and the control signal, that is, the above mode change or mode change setting is performed. A verification circuit 4 that sends a setting permission signal or a setting permission signal to a control unit (not shown), when the conditions of the key code input from the input medium A match a predetermined condition, For example, a RAM serves as a memory element for storing the information, 5 is a display circuit that displays whether the registration action is allowed, and 7 is the above-mentioned condition determination circuit 3° RAM.
4, a registration unit including a display circuit 5;

Note that the condition determination circuit 3 of the registration section 7 may be provided between the input means 1 and the setting switch 2.

FIG. 3 shows a specific embodiment of an operating circuit for increasing security by allowing only a specific authorized person to switch the setting switch 2.

In FIG. 3, the same operation circuit includes a relay circuit 17 for turning on the setting switch 2, a terminal section 15 appearing on the outside of the equipment system controller or reading device, and a terminal section 15 for registering a key code. A special tool 1 carried only by VC,'d authorized persons to short-circuit the terminal section 15.
6, and this tool 16 is inserted into the terminal portion 15 at the time of registration.

Next, the first operation will be explained in detail. First, the case where a key code is registered as an identification code will be described.

First, switch setting switch 2. For security reasons, this setting switch 2 is installed in a closed position inside the controller or reading device of the security system through a locking lid, and is configured so that a key must be used to open the lid. I'll keep it. Since this key is kept and carried only by authorized persons, a third party cannot easily register the key code. Now, the above-mentioned switching operation of the setting switch 2 is performed so as to connect the input means 1 to the registration section 7 side. Next, the key code is input from the input means 1 by using an input medium such as a card. This input key code is input to the condition determination circuit 3 of the recording section 7 via the setting switch 2. The condition determination circuit 3 determines whether or not the predetermined conditions stored therein match the conditions of the input key code. By providing this condition determination circuit 3, even if a person other than the authorized person attempts to input the key code, he or she will not know the code conditions and will also be able to hold an input medium that meets the predetermined conditions. Since the setting switch 2 is not locked, the registration operation cannot be performed, and in combination with the above-mentioned unlocking of the setting switch 2, a double security system is implemented.

As long as it matches the reverse Ki, everything can be registered as a key code. When the condition discriminating circuit 3 determines that the condition matches, the display circuit 5 displays the registration section, e.g. The rOJ mark is displayed 1, and the code of the input medium A input from the input means 1 is stored in the RAM 4 as a key code.The display circuit 5 may not only display visually, but may also display audio. If the conditions determined by the condition determination circuit 3 do not match, the display circuit 5 displays an indication that registration is not possible, for example, an "x" mark.In this case, naturally, the RAM 4
It is not stored as an identification code.

After the key code is registered as an identification code, the setting switch 2 is switched and the input means 1 is connected to the verification circuit 8. In this case, when the setting switch 2 is connected to the switch contact on the registration section 7 side, a separate delay circuit or timer is fully operated, and after a certain period of time set by them, the setting switch 2 is checked. It may be configured so that it is automatically switched to the switch contact on the circuit 8 side.

The above completes the setting and registration of the key code as an identification code. After registering this key code, when setting or changing the security mode in the security system, input the desired mode setting or change mode from the input means 1, and the input code is transmitted to the verification circuit 8 via the setting switch 2. The verification circuit 8 outputs i, RA
M4 reads the previously registered identification code, compares it with the sent code, and if they match, sends a control signal for mode setting, change, or opening/closing to the control unit, etc. Set or change the mode. Note that in this case, it may be appropriate to display that the operation is normal.

If the code input from the input means 1 and the identification code read from the RAM 4 do not match, a message indicating that the operation is erroneous is displayed, and an erroneous operation signal is sent to a remote security center or the like as necessary.

Note that this display means may also be used as the display circuit 5, or may be provided separately.

Referring again to FIG. 3, in the explanation of the operation of the embodiment shown in FIG. When using the operation circuit shown in , first, when registering a key code as an identification code, a special short-circuit operation tool 16, which only an authorized person should carry, is attached to the terminal section 15.
Insert into. Therefore, the potential Vcc is conducted to ground via the relay 17 and the short-circuit operation tool 16, and the relay 1
7 is activated. When the relay 17 operates, for example, the setting switch 2 provided as an operating contact of this relay 17
is switched to the registration section 7. Of course, it goes without saying that the setting switch 2 may be operated by extracting mechanical force from the operation of the relay 17. The operation after switching the setting switch 2 is the same as described above. Note that the short-circuit operation tool 16 may be provided with a switch section. In this way, there is no need to open the lid as described above, and the operation becomes easy. Furthermore, if the terminal section 15 for connecting the short-circuit operation tool 16 is inside the device, only authorized persons can use it, and the security accuracy increases.

As detailed above, according to the present invention, it is not possible to easily register or change a key code simply by performing a card operation on-site, but only authorized persons can register or change the key code. Therefore, a high degree of security can be ensured. In this embodiment, the registration and setting means is not limited to a card, but may be a numeric keypad, a switch, or the like.

FIG. 2 is a block diagram showing another embodiment of the security key code registration system according to the present invention, and sb is an embodiment having a control means for checking an input signal when registering a key code using an input medium. Now, in the embodiment shown in FIG. 2, 1a is encoded in the input medium A when registering or changing the key code, or setting the security mode or changing the mode using the card as the input medium. A reading head reads the key code magnetically or optically, and 16 is a reproducing circuit for converting the read key code into a digitized key code. constitutes the input means 1. 2
is normally connected to the verification circuit 8 as in the previous embodiment,
Only when registering the key code, enter the input means 1 into the registration section 7.
This is a setting switch that changes to the ' side.

The registration unit 7' registers the input means 1 according to the card insertion operation.
The verification circuit 8 is provided in a separate configuration from the verification circuit 8 that determines whether the information read in the key code matches the key code registered in advance.
A first buffer 9 temporarily stores data read in response to the first or second card insertion operation, and a first buffer 9 temporarily stores data read in response to the first or second card insertion operation. A second buffer 10 temporarily stores the data sent from the first buffer 9, and the data stored in the first buffer 9 and the second buffer 10 is transferred each time a card is inserted. and a discrimination circuit 11 that compares the two data according to a drive signal sent from the counter 14 when the counter 14 (to be described later) counts that the operation has been performed twice in succession; When both data of the key code manually entered by two operations in the discrimination time IA'rf11 are the same key code, the key code is stored in the RAM 12 as an identification code, for example, and the display circuit 13 displays the discrimination result. and a counter 14 for counting the number of operations.
14 will be completed. Further, in this embodiment, the condition discriminating circuit 3 is provided between the setting switch 2 and the first buffer 9 of the registration section 7'; however, as in the embodiment shown in FIG. may be made a component of the registration section 7'. Furthermore, it goes without saying that the switching operation circuit shown in FIG. 3, which has already been described, can be provided as the switching operation circuit for the setting switch 2 of this embodiment.

Next, the effects of the embodiment row 7 shown in FIG. 2 will be explained below.

The input means 1 is composed of a reading head 3 and a restraining circuit 4, and uses a card A on which a key code is recorded magnetically or optically as an input medium to register a key code, or to set or change a display mode. The case in which this is done will be explained in detail. In particular, in this embodiment, a confirmation method for setting a key code as an identification code, that is, a case where a key code is registered as an identification code only when the same card is used multiple times will be explained. First, when you want to register a key code as an identification code, switch the setting switch 2 and enter the registration part 7.
Connect the input means 1 to '. Next, the card Aff, which is an input medium, is inserted into the input means 1 according to the normal operation,
Perform removal. At this time, the insertion and removal operations may be performed manually or automatically using a machine using rollers or the like. Further, a method in which the key code is read when inserted or a method in which the key code is read when removed may be used. The key code information read by the known reading head 3 is encoded by a known reproducing circuit 4 at the subsequent stage, and then sent to the setting switch 2.
The information is inputted to the condition determination circuit 3 via the input information, and it is determined whether or not the condition of the input information matches a predetermined condition, as in the embodiment shown in FIG.

If the condition determining circuit 3 determines that they match, the information is further input to the registration section 7'; however, if it is determined that they do not match, the information is not sent to the registration section 7'. At this time, the display circuit 13 displays that the operation is erroneous.

Now, when a match is determined, the information from the input means 1 is sent to the first buffer 9 of the registration section 7'. At this time, the counter 14fd counts one operation to count fxJ. The first information is stored in the first buffer 9.

Next, when the card is inserted or removed again, the information read as described above is sent to the first buffer 7 via the setting switch 2 again. During this time, conditions are also determined. At this time, the counter 14 again counts the second operation and sets "0" as the return argument. When the second information is sent to the first buffer 9, the first information is pushed to the second buffer 10, and
Stored at O. Therefore, information corresponding to the second card operation is now stored in the first buffer 9, and information corresponding to the first card operation is stored in the second buffer i0. At this time, the first buffer 9 and the second buffer 10
Information is sent from each to the discrimination circuit 11. When the counter 14 returns to "0", it sends a drive signal to the discrimination circuit 11, and when the discrimination circuit 11 receives the l-i drive signal, the discrimination operation starts from each of the first and second picks. Compare the sent image information. Note that when the first buffer 9 and the second buffer 10 send information to the discrimination circuit 11,
It will be cleared. When the discrimination circuit 11 determines that the information matches, the display circuit 13 displays the registration, for example, displays a mark [○], and the information is written into the RAM 12.
If the information does not match, the display circuit 13 displays a registration error, for example, an "x" mark. At this time, RAM12
Naturally, I was not impressed and had to insert the card twice in order to register the key code as a job-specific code again. When writing is completed, return setting switch 2 to its original position.

In this embodiment, the key code is used as an identification code only when the information matches both times due to two operations. However, since this is used as an identification code, it is reliable. This is to improve sexual performance. Furthermore, in order to enhance the intelligence of the information, the number of times may be 2 or more.

When the card is inserted after registration, the information read by the reading head 3 and the reproduction circuit 4, that is, the key code, is input to the verification circuit 8 via the setting switch 2, and the verification circuit 8 stores it in the RA equipment VXl 2. Identification code 'l
: 'ttje and compare both codes. As a result of the comparison, if the results of the comparison match, a control signal, such as a security mode change, setting, or opening/closing signal, is sent out. If they do not match, a control signal is sent to indicate that they do not match.

Regardless of this example, the registration unit 7' may be used as a control device and is separate from the device, and includes the condition determination circuit 3, the first buffer 9, the second buffer lO1 collation circuit 8, the determination circuit 11, The counter 14 may be configured by a microprocessor. Further, the reading means of the input means 1 may be of a magnetic type or an optical type. Also, depending on the method of use, it is possible to identify only those with a special key code for a short period of time.

Further, in this embodiment, the initial W recording of the key code has been described, but the same applies when changing and setting a new key code as the identification code.

In addition, as a different configuration from the two embodiments described above, as shown in FIG. 4, the security accuracy can be improved by forming an embodiment in which the key code is input as a km-specific code using a registration/change tool. is also possible.

For example, the property (coser) code is stored in the memory circuit 20 of the registration/change tool 19, and this tool 1
Insert into the controller of the 'lfJ equipment system. Then, a current flows to the ground through the memory circuit 22 of the controller and the memory circuit 20 of the registration/change tool 19. Therefore, the Coser code stored in the memory circuit 22 in the controller is transferred to the comparison circuit 21 and also to the memory circuit 20 in the registration/change tool 19. The tested Coser code is sent to the comparison circuit 21. Comparison circuit 21 compares both codes and outputs an output to energize the relay only when the two codes match. Relay contacts (setting switch)
Since the key code is switched to the registration section side, the key code can be registered. The relay 23 is a relay for switching the setting switch 2, and the memory circuit 22 has a memory element R.
It may also be used as AM12.

In the above, various embodiments of the present invention have been described, but there is also a configuration in which there are a plurality of input means, one for verification for setting or changing the security mode of the security system, and one for registration for registering as an identification code. When adopting , no switching means is required. In that case, the input means for registration should be made so that only authorized persons can operate it! 1:9. In order to improve security accuracy, for example, the relay settings shown in Figs. 3 and 4 may be installed between the input means for registering the settings and the storage means, and should be disconnected at all times. For registration purposes, it is always closed using a locking lid, etc., and a key must be used to open the door.

You can.

As the switch means forming the setting switch 2 in the embodiments of FIGS. 1 and 2, various known devices can be used, such as a switch that switches when a magnet is brought close, or a physical switch such as a shape memory alloy or bimetal. A switch using a chemical phenomenon, a numeric keypad means, a key operation means, a push button type or a sensitive switch means, etc. can be used.

In addition, although RAM is used as the storage element in this embodiment, EP-ROM (Erasable
Programmable Read 0nly M
When re-registering the key code, the key code can be re-registered several dozen times by first erasing it with X-rays or ultraviolet light, etc., and then re-registering it.

Furthermore, according to the present invention, the key code can be checked according to predetermined conditions (for example, code data), digits, etc., code data and position conditions, and code blocks.As explained above, according to the present invention, As long as the predetermined conditions are met at the site, the key code can be registered as an identification code with a simple operation, and the predetermined conditions are accepted and only known to a person or a manual medium is maintained. I can't do it,
Furthermore, by using tools for short-circuit operation, etc., a complete security key code registration system with high safety accuracy can be provided. The operation for registering and setting the key code as an identification code is the same as setting the key code for changing the Wf equipment mode or security mode, and is simple.

Furthermore, since the key code registered and set on site is registered as an identification code, there will be no mismatch with the identification code of the controller or reader installed in the security system, and it will be recorded in the nuclear device and input medium. There is no need for management during shipping or installation to match the key code and identification code, so there is no need to worry about the hassle.
The storage element of the device can be used again simply by re-registering it using a manual medium in which a different key code has been recorded, which has the effect of reducing maintenance costs.
