Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an architectural shutter or the like which can be used in a system using individual keys and a master key, such as a door lock for a private room in a hotel or a shutter in a warehouse. The present invention relates to a control method and a control device for an electronic lock.

Conventionally, the control method for electronic locks and architectural shutters involves inputting a password from the key switch section of a numeric keypad or the like, or controlling the shutter after inputting it. It is controlled by entering the registered PIN number from the key switch section. For this reason, if there are many individual doors or shutters, such as in a hotel or warehouse, and each of these is used individually, each can be controlled by entering a separate password for security or management reasons. You need to be able to do it. However, in this case, since the registered PIN numbers are all independent and distinct, it is completely difficult to set a second PIN number like a master key necessary for management, and therefore it is difficult for those who use registered PIN numbers to was practically not used in such cases. Moreover, changing the registered PIN number requires changing the wiring and switch positions of the control unit installed in hard-to-see places such as in the ceiling or under the floor, so the user can easily enter the PIN code at will while in use. I couldn't change my number.

[Means and effects for solving the problem] The present invention has been devised in view of the above-mentioned actual situation to solve these drawbacks in two parts, and the first invention is a method for controlling the drive of architectural shutters or electronic locks. The first and second registered passwords are registered in advance in the control unit configured to be able to send control signals to the unit side, and a specific key (hereinafter referred to as M key) provided in the key switch unit is pressed. If you do not operate the key, enter the same password as the first registered password from the key switch section. If you operate the 1M key, enter the same password as the second registered password and the controller will input the same password as the second registered password. The second invention is characterized in that the control signal is sent to control the drive of the architectural shutter or the electronic lock, and the second invention is capable of sending the control signal to the drive control section of the architectural shutter or the electronic lock. The first and second registered passwords are registered in advance in the configured control section, and the key switch section has a specific key (hereinafter referred to as M key) and a password change key (hereinafter referred to as S key). If you do not operate the M key, enter the same PIN as the first registered PIN from the key switch section, and if you operate the 1M key, enter the same PIN as the second registered PIN. When inputting , the control signal is sent from the control unit to drive and control the architectural shutter or electronic lock, and the S key is pressed together with the first registered password or M
When inputted together with the key and the second registered PIN, the new PIN that is subsequently input is registered as the selected first or second registered PIN; The invention includes a key switch section into which a password can be input, and a first and second registered password are registered, and the input password from the key switch section matches the first or second registered password. A control section is provided to send a control signal to the drive control section side of the architectural shutter or electronic lock when the key switch section is operated. It is characterized by the provision of a specific key for selection.

With this configuration, although it is possible to control architectural shutters or electronic locks by inputting a password from the key switch section, in addition to the conventional input of only the first password. This allows control using two types of passwords, such as inputting a second password using the 1M key, similar to a master key.

[Embodiment] Next, two embodiments of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a key switch unit including numeric keys 1-N and control keys 1-g for inputting a necessary password as data for each digit and for switching operations. 2 is the control section, the number from key switch section 1,

)2-FS, error flag register indicating no error (
Hereinafter, this is simply referred to as an error flag. )2-FE, unlock or open the electronic lock or electronic shutter control device.

It has a drive control output section 2-CONT for closing and stopping operations, and a microcomputer for monitoring, determining, and controlling these.

The non-volatile RAM that constitutes the password registration section 2-M1.2-M2 is a C-MO5RAM equipped with a backup battery.
M, electrically erasable programmable ROM (EEFRO
M), or non-volatile RAM using a mixture of volatile RAM and EEFROM, etc. can be used.

In the embodiment of the present invention configured as described above, the functions, effects, operations, etc. of the control system using a password will be described below.

The functions and actions of the control system according to the present invention can be roughly divided into two types: the first is drive control of an electronic lock or architectural shutter, and the second is change control of a registered password.
These will be discussed below.

r, <Unlocking or Drive Control> Here, we will discuss the drive control of a normal electronic lock or architectural shutter using the first password.

1) When the first password is input using the numeric keys 1-N of the key switch unit 1, the judgment unit 2-CPU stores the digit sequence data from the key switch unit 1 in the input buffer 2-B, and inputs it. The number of digits is the specified value (four digits are shown as an example in the drawing)
Until the value is reached, the digit counter 2-CC is advanced by one count and waits for the next input. When the number of input digits reaches the specified value, error flag 2-FE indicates that the previous operation is normal.
and clear digit counter 2-CC. The contents of the input cover sofa 2B addressed by the digit counter 2-CC are compared with the old contents (first registered password) of the verification counter 2-PIN registration section 2-addressed by the contents of RCC, and the verification results match. , error flag 2-FE is set in response to the mismatch.
Set and reset each. Both counters 2-CC12
- Repeat this verification for the specified number of digits while incrementing ItCC one count at a time.

After the verification is completed, the contents of the error flag 2-F[E are given as they are to the drive control output section 2-CONT of the electronic lock or the control flag 2-FC of the electronic shutter control device, and the input password is St, the recorded password. If it matches the number, the error flag 2-FE remains set [IJ, if there is a mismatch even in the - digit, the error flag 2-FE is set.
The value is set to ``0'' in the determination unit 2-CI''U. Therefore, the verification result is as follows.

2) In the case of verification result A, electronic lock If the verification results match, “1” is given to the drive control output unit 2-CONT from the judgment unit 2-CPU, and as a result, the drive control output unit 2-CONT initiates the unlocking drive. A signal IK is generated and an unlocking operation is performed (if they do not match, "0" is given and the unlocking operation is not performed).

B. In the case of architectural shutters, if the matching results match, "1" is given to the control flag 2-FC and a control permission signal ICNT is sent to the input control unit 2-IC.
is given (if they do not match, rOJ is given and the control permission signal ICNT is not issued). After that, press the control key t-
When any of the shutter drive open key "Δ", close key "" or stop key 1" in C is operated, the judgment unit 2-C
From the PU, a shutter drive control signal DCN according to the input is sent.
T is sent out, and the drive control output section 2-CONT outputs corresponding shutter drive signals (open signal ■0, close signal IS
, stop signal ID) is generated to control the opening, closing, and stopping operations of the shutter.

3) When the M key is operated If the M key, which is the password selection key (specific key) among the control keys 1-C, has been operated prior to inputting the password, the judgment unit 2-CPU recognizes this. Identification and verification counter 2-
The leading number of the memory as the second password registration section 2-M2, for example "8", is set in the RCC, and the password flag 2-FS is set. Therefore, if you input the second password after pressing the M key, the 1 judgment unit 2-CPU will check the contents of the input buffer 2B (
The entered PIN) will be compared with the contents of the second PIN registration section 2-M2 (second registration number), and if the input PIN matches the second registration number, the electronic It becomes possible to unlock the lock or control the drive of the electronic shutter control device. After unlocking or controlling (does not take place in case of mismatch), all registers and flags are returned to the initial state of waiting for input.

In this way, when controlling the electronic lock or architectural shutter, a double password can be selected and used depending on whether or not the M key is operated. Therefore, the person who operates the M key can be used as the master key. Moreover, these two registered passwords are stored in different addresses of the first and second password registration sections, that is, the nonvolatile RAM, and are switched by the M key of the key switch section 1.

Therefore.

The first and second passwords can be set independently without any confusion.

n, <Change of PIN> 1) For electronic locks, changing the PIN starts with the operation of the S key, which is the PIN change key in control key 1-C, at the beginning of input, and for architectural shutters, as described above. The process starts when the S key is operated after the shutter drive control is enabled.

A. In the case of an electronic lock, if the S key is operated first, the determining unit 2-'CPU identifies this and sets the password change flag 2-FX.

While the change flag 2-FX is set, the judgment unit 2-CP[J cannot send the unlocking control signal DCNT to the drive control output unit 2-CONT, and does not send the unlocking control signal DCNT to the input control unit 2-IC. Issues an input permission signal ICNT. If you want to change your first password here, immediately input your old password using the numeric keys l-N. The entered PIN is input to input buffer 2-H.
The password is stored in the password and compared with the registered password in the same way as in the case of unlocking the lock.

When the comparison results match, a password input permission signal ICNT is sent from the CPU 1 to the input control unit 2 IC.
is issued, acceptance of input of new PIN numbers is started, and the new PIN numbers are stored in the input buffer 2-B in the order of input.

If there is a discrepancy when entering the old PIN, all registers and flags are immediately cleared and the control status is changed to input control unit 2.
- Issues an input permission signal ICNT to the IC and waits for input in the initial state.

B. For architectural shutter control devices, change the password using the shutter drive control permission signal DCNT.
The game begins by operating the S key while .

The judgment unit 2-CPIJ identifies this by inputting the S key and sets the change flag 2-FX.

While the change flag 2-FX is set, the judgment unit 2-CPU cannot send a drive control signal to the drive control output unit 2-CONT, and issues an input permission signal ICNT to the input control unit 2-IC. .

Next, in the case of changing the first password, input reception of the old password is immediately started, and the old password is stored in the input buffer 2-B in the order of input.

2) After inputting all digits, clear the digit counter 2-CC and check the contents of the input buffer 2-B, which is addressed by the contents of the digit counter 2-CC, with the password registration section 2, which is addressed by the contents of the counter 2-RCC. -Write to M1.

While incrementing both counters 2-CC12-RC and C by one count, writing of the specified number of digits is repeated, thereby registering a new first password.

After the registration is completed, the control state clears all registers and flags, and sends an input permission signal ICNT to the input control unit 2 to IC.
In particular, the input of the initial control state is returned.

3) On the other hand, if you want to change the second registered PIN, press the S key followed by the M key for electronic locks, or enter the M key and the second PIN for architectural shutters to allow shutter drive control. By operating the S key after obtaining the password, the first password is Just do the same operation as changing the number. While the password flag 2-FS is set, the password registration section at the time of verification and writing is the second password registration section 2-M2, and the start address of the nonvolatile RAM is set to, for example, "8".

m. <Initial Setting of PIN Number> In the above control method of the electronic lock or shutter control mechanism, the contents of the non-volatile RAM constituting the PIN registration unit 2-M1.2-tag are not determined immediately after manufacture. This is the same as the fact that in general RAMs, the data is not fixed immediately after the switch is turned on. For this reason, a situation arises in which the password is unknown at the beginning of assembly.

In order to avoid this drawback, in this embodiment, a clear switch 2-CL for the first password is provided in the control unit 2. When the clear switch 2-CL is operated, the determination unit 2-CP
In U, for example, forced values of all "0" are set and stored in the first password area of the non-volatile RAM. Therefore, the first password is set to r 0000 J for all digits, and it is only necessary to change and register the password to any other password using this as a reference.

On the other hand, the second password is never cleared by the clear switch 2-CL. If it is possible to clear the password, there is a risk that the password will be cleared without the user of the second password being aware of it, and if we try to avoid this, the user of the first password will be able to change the first password at will. This is because the freedom to clear the game as appropriate will be restricted.

Since the second password is mainly used by the administrator for special supervision, the restrictions at the time of setting may be strict. Therefore, in this embodiment, on the condition that the first password has been cleared, the second password can be cleared by performing the following operation.

A. Procedure for electronic lock S key, first password (for example, r 0000 J only)
, M key, second PIN number.

First, manually set the password change flag 2-FX using the S key, and then set the forced value, which is the first password.

For example, by inputting r 0000 J, the contents of the first password registration section 2-M1 are checked against the contents of the all-digit input buffer 2'H, and if they match, the password flag 2-FS is set by inputting the M key. A specific value, for example "8", is set in the verification counter 2-RCC, and the digit counter 2-CC is cleared in preparation for inputting a new second password.

B. Input sequence for architectural shutters - beak identification number (roooOJ only), S key, M key,
Second PIN number.

First, enter the forced value that is the first PIN, for example rooo.
By inputting "o", control flag 2-FC is set and drive control of the electronic shutter control device is permitted. When the S key is input here, the change flag 2-FX is set and the control flag 2-FC is reset. Next, when the M key is input, all digits of the contents of the password registration section 2-old and the contents of the input buffer 2-B are compared, and if they match, the password flag 2-FS is set and the verification counter is set. Set "8" and clear the digit counter 2-CC to prepare for inputting a new second password.

In this way, when all digits of the new second PIN are input, the contents of the input buffer 2-B are written to the second PIN area of the non-volatile ItAM as the PIN registration section.
Clear all registers and flags, input control unit 2-IC
control and return to the initial control state waiting for input. From this point on, a new second PIN number will be used. On the other hand, if the first password entered is not the forced value, for example roooOJ, an error will occur when the M key is input, and all registers will be
Clears the flags and returns to waiting for input.

With this method, the password can be easily set when necessary, but the clear switch 2-CL is not installed on the keyboard like the key switch section 1, but inside the device like the control section 2, so that it cannot be used except when it is specially necessary. It is necessary from the viewpoint of crime prevention to prevent operation.

[Effects] 1. Since the present invention is constructed as described above, the PIN number input from the key switch section is controlled using two different PIN numbers depending on whether or not the M key is operated. Therefore, if you have multiple locking doors or shutters and each requires a different PIN number (hotels, warehouses, etc.), you can use a separate primary PIN number for each door or shutter. By assigning a common second password to the entire system, the first password has the characteristics of an individual key, and the second password has the characteristics of a master key, making management extremely convenient. Moreover, only those who know each password can easily and arbitrarily change the registered password from the key switch section, which is not only important for management purposes but also for security reasons. Since it is extremely excellent, it can be applied to hotels, medical clinics, apartments, etc., or to control the locking of show windows, warehouse shutters, etc., and the effect is extremely significant.
