Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic lock that controls the opening and closing operations of a shutter or a door.

[Prior art and problems to be solved by the invention] Conventionally,
In this type of electronic lock that opens and closes shutters or doors, unlocking is determined by inputting a registered password code that is a combination of numbers, symbols, and one character that is stored in advance in the control unit, and the opening and closing control is performed. We are making it possible to do so. However, in this case, because the same PIN code is operated many times each time the key switch is opened or closed, only certain key switches become dirty and the PIN code is easily read, resulting in poor security.As a defense against this, measures such as changing the PIN code frequently are taken. had to be taken.

Moreover, one type of numeric keypad usually has 10 types from 0 to 9, and even if you combine them, for example, if you have a 4-digit pin code, you can calculate only 10,000 different pin codes. It was requested. However, increasing the number of digits in the PIN code has the disadvantage that people will frequently forget the number, so it is impossible to increase the number of digits unnecessarily.

c. Means for Solving the Problems and Effects] The present invention was devised in view of the above-mentioned actual circumstances in order to provide an electronic lock for a shutter or door that can eliminate these drawbacks.

This is an electronic lock for a shutter or door that is controlled to open by inputting a password from a code key switch. The device is characterized in that a mode switching means is provided in which a password code mode is set and the mode switching of the password is performed by a changeover switch, and the changeover switch is a switch capable of switching between a plurality of ON and OFF states. It consists of a group of jumper wires or a group of jumper wires, and is installed in a separate location from the operating section.

Based on this configuration, the present invention allows a plurality of pin code modes to be set by input combinations or input orders of unit codes, and allows easy mode switching by operating a changeover switch, thereby improving crime prevention. It is something.

[Embodiment] Next, an embodiment of the present invention will be described based on the drawings. In the drawings, 10 is an input operation unit such as a keyboard for operating the shutter, and 20 is an electronic lock control unit. It consists of

This input operation unit IO is equipped with a lamp 1, a buzzer 2, and a keyboard 3, and the keyboard 3 includes open, close, and stop pushbutton switches υ, D, S, and a clear switch CL.
and numeric keys 0 to 9 for input are provided, and the clear switch CL is used to clear the input of an incorrect code by pressing the button, and the buzzer 2 is used to control the control state. This is to notify the person and guide and instruct the next operation. On the other hand, the electronic lock control section 20 includes an output section 4, a central control section 5. Memory 6, clear switch 7 to clear the PIN code, mode switch 8
etc. are equipped. In addition, the lamp 1 uses a red lamp using an ordinary light emitting diode (LEI).
This lamp 1 blinks when inputting an operation, for example, and turns on when inputting a password for registration. Also, if you want to clear the already registered code, set it so that it will be cleared by pressing the clear switch 7 while the above-mentioned lamp 1 is blinking (or when the buzzer 2 is sounding intermittently). It is. In addition, the centralized control unit (CPtJ
) is equipped with an interface to perform central functions such as logical judgment and calculation in combination with various peripheral circuits, and is used to control the time function of the electronic lock device 30, i.e., the ringing time when the key switch is operated, and the control mode of the shutter and door. This outputs a signal indicating the time of the Dharma priest. Based on input data from the input operation unit 10, contents of registers, memory, etc., input is controlled to be accepted or rejected in response to determination of the control state, and the type of notification signal of the buzzer 2 or lamp 1 is specified. It is used to input information from the input operation unit IO by making various judgments about various setting conditions such as PIN code registration, number of digits setting counter, time limit timer, input information such as PIN codes accumulated in the input buffer, and control status. Control whether or not the operation can be performed. Furthermore, whether or not the input signal based on the input combination or input order of a group of unit codes (for example, a four-digit numerical input code from the input operation unit 10, or a single input from a push button switch), which will be described later, matches the registered PIN code. A signal is sent to the control panel 40 of the shutter, door, etc., and if there is an incorrect operation, wrong code, or abnormal operation time, it is rejected and the buzzer 2 is continuously sounded. It is something that does.

Furthermore, if there is a signal to change to a new PIN code from the input operation unit 10, confirm that the re-recording has been completed, or send a signal from a separate detector (not shown) to indicate whether the shutter or door is fully open, fully open, half open, etc. Comprehensive information processing and control, such as issuing instructions to lock and lock the locks, is performed in response to this information. Furthermore, 1
1 is a cable, 50 is an opening/closing machine that drives the shutter 6.Furthermore, the mode switch 8 is, for example, mode switch A, Q.
, C, D, IE, F, G, H and jumper wire, 1
(No. 9 switch) allows nine types of mode operation states to be set, and the registered password code mode based on the unit code group and the operation order of the unit code group to be described later are addressed.

Now, from the keyboard 3 to the memory 6 by an appropriate known means,
PIN code (for example, 4) stored as a unit code group in
For example, set the input order of X and the release push button switch U to each address XA-H of the mode switch.
, A=X, B=XU, C=UX, D=XX, E
= XXU, F= UXU, G= XUX, H=
Assume that each is set as UXX and stored in the memory 6. In this case, even if the unit code group is only two types, X and U, by switching the mode switch 8 to A-H, it can be used as eight types of password code keys in this embodiment.

Furthermore, for example, the password code mode for opening this shutter or door is set to E (XXU) station. To open the shutter or door, first enter unit code group X (enter 1234 on keyboard 3)
is the primary input. Then, the central control unit 5 inputs the unit code group X again as a secondary input within the set 11 seconds.
first judges whether the unit code group X of the primary input matches 4J and the recorded PIN code, then the unit code group X of the secondary input is input within 11 seconds, and then the tertiary unit code group It is determined that U is input within 11 seconds and no code signal that follows within that 11 seconds is input, and it is determined whether this input signal is a signal of only one digit, two digits, or three digits. If it matches the password code mode E set exclusively for this shutter or door, an OK display instruction is sent to the lamp 1, and the electronic lock device 30 is unlocked and the opening operation is performed from the output section 4 to the shutter or door. This is an instruction from the control panel 40 to the opening/closing machine 50, so that the operator knows that the electronic locking device 30 has been unlocked and can open the shutter or door by operating the switch U again.

In addition, when closing the shutter or door, you can do so by inputting E (XXU) using the same method as described above, confirming the short OK sound, and then pressing the closing pushbutton switch D. can do.

In this embodiment, the mode switch is set to A=X for the sake of explanation, but in this case, there is no order combination of push buttons, etc., and the lock can be unlocked simply by inputting the PIN code (1234). , this address may be left unused or set to a combination of A=υUx, DXD, etc. in a different order. In addition, if you do not change your password, you will only need to use the same key switch (1234) for the numeric keypad, but due to dirt etc., Yakina noticed that this 4 type numeric key switch was being used, and Even if the 4-digit signal created by the permutation combination procedure is decoded, it will not be possible to unlock the door with just the identification number, and an alarm will go off to prevent theft and y@. Therefore, safety will be further improved.

In this way, in the present invention, open/close push button switches etc. that are spelled out by input code signals! If the plurality of combinations and order of the lt-order code group match the N sharp cut signal, the central control unit 5 determines that it is accurate as described above, and the input operation unit 10
An instruction is issued to the lamp 1, buzzer 2, etc., and the electronic lock of the electronic lock 30 is released. As a result, the three push button switches will no longer be used for unit code groups, but will be used only for operating the shutter or door, so U will be open, S will be stopped, and D will be closed. Based on this, shutters and doors can be controlled.

Therefore, even if the PIN code is deciphered due to dirt on a specific key switch, such as in the case where the lock is unlocked using only a specific numeric keypad switch, as in the case of the conventional method, even if the PIN code is The lock cannot be unlocked even by a combination of unit codes, and can only be unlocked by inputting the input code in the order of combinations of multiple unit codes.It is extremely secure, and the number of digits in the PIN code can be increased. It is possible to increase the number of passwords several times without increasing the number of passwords just by using the mode changeover switch.
This will improve crime prevention.

[Operations and Effects] In summary, since the present invention is constructed as described above, a plurality of pin codes are set by the combination or order of the unit code groups set by manual input of the code key or opening/closing switch, and It can be selectively switched using a changeover switch. Therefore, even if the sheet metal PIN code is decoded due to dirt etc. due to the use of only a specific key switch as in the past, there is no chance of ``incorrect code input'' if the PIN code is used alone. This means that the lock cannot be unlocked, resulting in extremely high security. Moreover, the PIN code is not unnecessarily long, and can be set as an easy-to-remember combination or order of unit codes, thereby minimizing the possibility of forgetting the PIN code.
