Description

Detailed Description of the Invention The present invention provides an electric lock control device that compares an input code from a numeric keypad or the like with a pre-stored code and unlocks the electric lock if they match. This invention relates to an electric lock control device that has extremely high performance and is easy to operate and manage.

Generally, as shown in FIG. 1, an electric lock control device includes a numeric keypad operating section 1, an electric lock 2 provided on the side of a wall W corresponding to a knob N of a door D in response to an output signal from the numeric keypad operation section 1, and an electric lock 2 provided on the side of a wall W corresponding to a knob N of a door D. It is constituted by a control section 3 that drives the control section 3. The operation is based on the assumption that door D is currently locked: (a) Numeric keypad 1
Enter the code corresponding to the encryption code by operating a.

(b) Compare the preset code with the input code to determine if they match or do not match. (C) When they match, an electric lock drive signal is sent to the control unit 3, and the output drives the electric lock 2 to unlock it. (d)
Next, turn knob N to open door D and enter the room.

The above is the basic operation when unlocking an electric lock,
The automatic lock type locks when door D is closed.

On the other hand, in the alternating operation type, when a code is input using the numeric keypad 1a, locked items are unlocked and unlocked items are locked.

Conventionally, some electric lock control devices such as this type of electronic lock can change or erase the code hood, and display when the input code and the code match, but there are measures against malfunctions to maintain code confidentiality. It was not sufficient in terms of operational convenience, management issues, safety, and reliability.

This invention was made in view of the above problems, and is applicable regardless of the type of electric lock, such as the automatic lock type or the alternating action type. (Dwrrrrr
y Code) to prevent others from memorizing the code while operating the key, and by clearing the code registration area with a number not in the key during the initial operation when the power is turned on, 10, 0, etc.・By preventing the electric lock from being unlocked by inputting "0" and clearing the count of the number of erroneous operations after a certain period of time after the key is no longer touched, in addition to the number of erroneous operations by outsiders, If you set the circuit to registration mode by operating the cipher code registration switch, you can set the code to verification mode after a certain period of time regardless of whether you have registered or not, so that a single erroneous operation will not cause an alarm. By making the signal sent from the operation unit to the control unit a pulse signal, the electric lock can be unlocked even if the drive signal is not output by cutting or shorting the wiring. It prevents the risk of being locked, and allows you to turn on and off various operation confirmation sounds, warning sounds, and other display sounds using the numeric keypad, preventing nuisance caused by neighborhood noise, and achieving an extremely high level of safety. The purpose of this invention is to provide an electric lock control device that is excellent in terms of reliability management.

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

In FIG. 2, the operation part A is shown within the frame of a dashed line,
The numeric keypad 4 is provided with ten numeric keys @0# to 19#, an "M" key used when registering an encryption code, and an @OP# key for starting a processing operation. The lamp 5 is placed between the numeric keypad 4, and the electric lock 2 (Fig. 1)
The result of the operation is displayed. The key data collection unit 6 receives a signal 6at6bt from the input from the numeric keypad 4.
Outputs 6c and 6d. The signal 6a is for sounding an alarm indicating that the numeric keypad 4 has been pressed correctly. Signal 6b inputs data to data buffer 7.

The signal 6C is a start signal for starting the verification or registration operation, and is output when the 10P'' key on the numeric keypad 4 is pressed.

The signal 6d is input to the 5-minute timer 8, and every time a key on the numeric keypad 4 is pressed, the 5-minute timer 8 is cleared and counts up from 0 again. to clear its counter (not shown).

The data buffer section 7 is a shift register (not shown).
11$, and when the data is input by signal 6b, the data enters the shift register serially,
The data overflowing from the shift register is picked up one after another.The signal 7a output from the data buffer part 7 is the contents of the shift register as it is, and is used for writing or reading the encryption code. The other signal 7b that is output is address data and is sent to the write control section 14.
is input. The signal 10b from the initial section 10 is input to the data buffer T as memory clear data. The collation section 11 is for collating the encrypted code with the keyed-in data, and receives a dummy code by the signal 7a and a hood consisting of the input code, and receives the encrypted code from the memory part 12 as the signal 12a. Discrimination part 1
A verification start signal 15a is input from the verification section 1.
The signal 11a from 1 is sent to the memory address control section 13, and the registered code is sent to number 111g.

The signal 11b is output when the verification result is OK (yes), and the signal 11d is output when the verification result is Nfl (no).

A plurality of encryption codes are registered in the memory part 12. Signal 7a from data buffer 7 is input as an encryption code, and the encryption code is output as signal 12a. The memory address of the memory part 12 is controlled by the signal 13& from the memory address control unit 13, and the write control unit 1
A write pulse is given by the signal 14a from 4 when registering the encryption code.

The write control s14 serves to write a code into the memory part 12, and when a signal 18a is given from the AND circuit 18 for writing an encryption code and a clear code, the encryption code is written and the code is written from the initial part 10. When signal 10a is input, a memory clear code is written. An address signal indicating the number of the code to be written is input by the signal 7b.

The memory part 1 is
A write pulse is applied to 2. A memory address control signal is applied to the address control unit 13 by a signal 14b from the write control unit 14, and a buzzer signal is applied by a signal 14c to notify which code has been written.

The initial section 10 is for clearing the memory when the power is turned on, and clear data (this data is 115'' in hexadecimal) is given as memory write data via the data buffer section T. .Signal 1
A command to write clear data to the memory is given to the write control unit 14 by 0a, and as a result, all ""F" food (hexadecimal) is written to the memory.

The reason for doing this is that, for example, if you clear all@Q'' and do not write a code, if you input ``a#'' from the numeric keypad 4, the electric lock 2 will operate. Such cases are quite conceivable. If there are multiple encryption codes, for example 3 codes, and the user registers two but not one, the code "all@0" is also encrypted and may cause malfunctions.

When the "OP" key is input, the determining unit 15 determines whether the task is to be verified or to be registered, and issues each task command. Signal 15a is for verification, and signal 15b is for registration. The signal 15a is sent to the verification section 11 to perform code verification, and is also sent to the buzzer code verification section 16.
It is checked to see if it matches the buzzer code.

Next, the write control timer 17 will be described. When registering an encryption code, the encryption code registration switch 8B of the control section B must be operated first.

This operation signal BC is input to the write control timer 17, and a 5-minute timer is activated, so that writing is not possible unless the encryption code is written during this time. The reason for this is that if the code hood registration switch Sg remains operated, the code may be broken by mistake. Therefore, writing is not possible after a certain period of time, making the system more secure.

This write prohibition is performed by an AND gate 18. - When the encryption code registration switch 8B is operated again (turned OFF), the write control timer 17 is cleared.

The buzzer hood verification unit 16 checks whether the buzzer code set in advance (memory) matches the code entered using the numeric keypad 4. If they match, a touch confirmation sound from the numeric keypad 4 is heard, Encryption code registration Kiyone, Encryption" Turns on and off before the code verification result. These controls are controlled by OR gate 19. AND gate 20.
．． It is held at Or Gate 22. Since this operation is simple, the explanation will be omitted.

The erroneous operation counting section 9 counts the number of times when the code entered from the numeric keypad 4 is erroneous, and when the number of times exceeds a certain value, a buzzer BZ is used to issue an alarm. The input signal 9b inputted as the input signal 9a by the signal 11d and inputted via the OR gate 23 is for clearing the number of the counter, and the output signal 9c
enters the alarm section 21, where the W alarm sound is generated and the buzzer Bz is sounded, at the same time clearing the erroneous operation counter section 9. In addition to the above conditions, clear conditions include when the result of the verification unit 11 is OK (yes), and when the numeric keypad 4 is not touched for a certain period of time or more.

Next, the signal converter 24 will be described. O in the matching section 11
When it reaches K, the electric lock 2 is driven, but if the drive signal was sent at a DC level from the operation unit to the day before the control, the 11'EM during this time would be disconnected.
By short-circuiting with other lines, an OK signal is sent to the control unit B by the signal 11b. In order to prevent this danger, the signal from the operating section A is converted into a pulse signal by the signal conversion section 22 and sent.

Next, the operation of this electric lock control device will be explained based on the above configuration.

First, the case of registering a cipher will be described. Assuming that three codes can be registered, the first one is ``123''.
4”, press numeric keypad 4 to 1M12340.
If you press the keys in the P order, /! 61 encryption code -
12341 is registered. However, registration is only possible if the circuit is in registration mode. Then the second
To register "@573" in the same way, 2M5730P
Press the keys in this order. By doing the same with the third cipher, three types of ciphers can be registered.

Here, you will hear a buzzer to confirm that the registration has been completed correctly. That is, when the registration is successful in A1, the buzzer Bz sounds once with a long tone. When it is successfully registered to A2, a long tone sounds twice. /When registered to I63, a long 3M tone sounds. If registration is not successful, four short beeps will sound.

When registering the above code, the gummy code and code are entered as input code data. All data input is numeric and is captured as hexadecimal. However, the keys contain 10 numbers from ``0#'' to @9m, and numbers 10 to 15 (decimal table) are not captured.

These numbers are used as the memory key (M key) OF key and memory clear.

Next, the operation of the shift register (not shown) of the data buffer section 7 will be explained with reference to FIG. This shift register receives the signal 1 from the initial section 10 during initial operation.
Cleared to all "F" by 0b. Here, each numerical data is composed of 4 bits, and "F" is expressed in hexadecimal.

Next, press numeric keypad 4 @l #, @I 2”, @3”, 1
If you press 4'', the shift register will change as shown in Figure 3 (,
)become that way.

Next, following the dummy code "5578", '12
The shift register when the code hood 34' is input is shown in FIG. 3(b).

FIG. 4 shows the state of the code hood in the memory part 12. (a) shows the state when it is cleared at the time of initialization, and it is all 1F". (b) shows the code code "'
1234 ' indicates when it is written.

Part 5 shows the method of matching the keyed-in code with the stored encryption code. The matching is performed by ignoring the same digits as the three digits (FIG. 5(b)).

Therefore, in this input code, "5578" becomes a code that is not verified, that is, a dummy code 1.

In the above, the number of digits of the encryption code is shown as eight, but it goes without saying that any number of digits may be used. Moreover, even if it is a constant, it is not fixed.

It should be noted that the encryption code registration switch 8B is placed in the control section B in order to protect the written code. This is because it is conceivable that the stored code may be destroyed by operating the encryption code registration switch Bg.

The control section B drives the electric lock 2 in response to the signal from the operation section A, and the result of the operation of the electric lock 2 is sent to the operation section A, and the completion of locking is indicated by the lamp 5.

Note that the encryption code registration switch Bs is provided in the control unit B, but this switch is of a lock type, and is turned on during registration and turned off during operation, that is, verification.

Next, another embodiment shown in FIG. 6 is an input/output control section (hereinafter referred to as I10 control section) 2 of the circuit of the embodiment shown in FIG.
5 has been added, and the same parts in FIG. 6 as in FIG. 2 are designated by the same reference numerals and the explanation thereof will be omitted.

When using this example at home, etc., the check procedure is to check that the door is locked when you go out, check if you have forgotten to close the gas valve, check that the lights are off, etc. before locking the door. is incorporated into the sequence.

That is, the OK signal 11b from the matching section 11 is I10.
It is connected to be input to the control unit 25, and is also connected to the control unit B.
Various information of the terminal such as door lock, gas valve electricity, etc. is inputted to I10 as a signal Be.
It is output to the control section 25. The I10 control unit 25 judges the information of the signal SO, and if it is not normal, it outputs the signal 25.
c to the control unit and gives a control command to send a drive signal to a terminal that is not under royal authority.

This control signal 25c is a signal for normalizing an abnormality in the terminal. Specifically, for example, if the gas valve is open, the controller B is commanded to close it. I
10 Control s25 sends a signal 25d and an OK double signal to the signal converter s21 when it is determined that all the terminals are normal, and sends a pulse signal from the signal converter 22 to the control unit 1 to send an electric lock drive signal to the control unit B. send out.

If the terminal is not normal, the information from the control section 25b is checked again, and if the answer is YES, a drive signal is sent to the electric lock 2 to lock the electric lock 2 in the same manner as described above.

11 like this! In ti, it is possible to provide a safer system for locking by combining the yes signal 11e from the verification unit 11 and the function of determining the status of the terminal unit by the I10I control unit 25.

Furthermore, various sensors such as fire and crime prevention sensors can be used together as terminal information.

Furthermore, as another application, when the numeric keypad 4 is used by people from different companies, such as Company D, Company 1, etc., it may be possible to manage which person has used it.

In the event of damage to a building, it may be necessary to determine who is responsible.

In such cases, a plurality of prepared encryption codes are assigned to each company. And which code is used and verification OK
A signal 11e is output from the collation unit 11, inputted to the signal conversion unit 24, and sent to the control unit B as a different pulse signal.The control unit prints the information on the printer together with the clock information. It is convenient for management.

In the above, different pulse signals mean that the pulse signal of Company D and the pulse signal of Company 1 are different pulse signals, and the electric lock 2 operates even with different pulse signals.

As described above, according to the present invention, when entering a code code from the numeric keypad, the gummy e code is entered before the hood and is ignored during verification, so that it is difficult for others to memorize the code. Highly secure in terms of confidentiality.

In the initial operation when the power is turned on, the code registration area is cleared with a number that is not on the numeric keypad, so when registering a code hood with U number, the code "0, 0,
In addition to preventing unlocking when entering ``-0'', even if only one cipher hood is registered, all other hoods have been removed, so only one number will be accepted as before. It's functional and convenient, but it's also highly safe.

Since the count of the number of cavity operations is configured to be cleared after a certain period of time after the key is no longer touched, the number of erroneous operations by a person concerned is not added to the number of erroneous operations by an outsider, and unnecessary alarms are not issued.

If the circuit is set to registration mode by operating the encryption code registration switch, the circuit is configured to enter verification mode after a certain period of time regardless of whether registration is performed, and the switch for writing the code is turned off. It automatically switches to verification mode and prohibits registration mode, which is effective in making the system more secure.

Since the signal to drive the electric lock is sent from the operating section to the control device as a pulse signal, the danger of unlocking the electric lock due to disconnection of wiring, short circuit, etc. is prevented.

Turns on the touch sound to confirm whether the numeric keypad has been pressed correctly, the code hood registration sound, and the verification result sound.

Since turning off is done using a code, it can be done by operating a key switch, and it is a cheaper switch that saves installation space.
It can be improved in terms of operation, and it can prevent noise from bothering the neighbors at night.
