OFF (or OFF to ON) In short, it is sufficient if it can be confirmed that the operation switch part 1 is detached from the mounting bracket 11).

FIG. 3 is a block diagram of the electric lock device of the present invention, and 20 is a microcomputer (hereinafter referred to as microcomputer) of the control section 2.

Next, the operation of the electric lock device of the present invention will be explained.

Unlocking using the password from outside the room is performed by operating the operation switch section 1.

First, press the * key on keyboard switch 1a. This * key is used to enter the PIN number on the microcomputer 20.
This is the start signal key to notify the driver. For example, if the preset PIN is 7301, *
When you input 7, 3, 0, 1 using the number keys following the key, the microcomputer 20 receives this input signal and compares it with the number set by the password setting switch 4.
If they match, an unlocking signal is sent to the electric lock 3. The electric lock 3 is unlocked upon receiving this unlock signal.

To unlock from the indoor side, an unlocking signal is sent to the microcomputer 20 by pressing the unlocking switch 5 of the control unit 2. Upon receiving this signal, the microcomputer 20 sends an unlocking signal to the electric lock 3. The electric lock 3 is unlocked.

Next, when locking from the outdoor side, by pressing the # key on the keyboard switch 1a of the operation switch section 1, the microcomputer 20 sends a locking signal to the electric lock 3, and the electric lock 3 is locked. However, when a gate opening signal is input to the microcomputer 20 from a gate detection switch (not shown) built in the electric lock 3, the microcomputer 20 does not send out a locking signal.

On the other hand, when locking from the indoor side, by pressing the lock switch 6 of the control unit 2, the microcomputer 2
sends a locking signal to the electric lock 3 and locks the electric lock 3.
will be locked. If the gate opening signal is inputted to the microcomputer 20 from the electric lock 3, the microcomputer 20 does not output a locking signal as in the case of locking from the outdoor side described above.

The unlock lamp 7 is an indicator lamp that lights up when the electric lock 3 is unlocked, and the microcomputer 20 unlocks the lock by receiving a signal from a lock/unlock confirmation switch (not shown) built into the electric lock 3. When the lamp 7 is unlocked, it is turned on, and when it is locked, it is turned off.

The lock lamp 8 is an indicator lamp that lights up when the electric lock 3 is locked, and when the microcomputer 20 receives a signal from the lock/unlock confirmation switch built in the electric lock 3, On the other hand, when the electric lock 3 is locked, the lock lamp 8
lights up and turns off when the door is unlocked. The door opening lamp 9 detects the open/closed state of a door or gate using a reed switch (not shown) built into the electric lock 3 and a magnet (not shown) arranged on the fixed frame side, and receives this detection signal. Accordingly, the microcomputer 20 turns on the light when the door or gate is opened and turns off the light when the door or gate is closed.

Next, a case where an attempt is made to remove the operation switch section 1 by mischief or malicious intent, or a case where the operation switch section 1 is mechanically destroyed will be explained.

When the mounting screws 16' and 16'' are removed and the operation switch section 1 is removed from the wall surface 13 to which it is attached, the micro switch 12 built into the operation switch section 1 will be removed.
Since the lever 12 connected to the micro switch 12a is separated from the lever holding portion 18 of the mounting bracket 11, the lever 12 is projected by the repulsive force of the spring of the micro switch 12a. Therefore, the micro switch 12
Contact a changes from OFF to ON (or from ON to OFF)
The microcomputer 20 catches this change.

Based on this signal, the microcomputer 20 first confirms the locked state of the electric lock 3, and if it is in the unlocked state, immediately outputs a locking signal and locks the electric lock 3.

Further, the alarm device 1c provided in the operation switch section 1 is made to sound. An alarm sounding signal is also output to an alarm section 10 provided in the control section 2 to notify people in the room that the operation switch section 1 has been removed or destroyed.

In addition, the operation switch part 1 was destroyed and the lever 1
2 is detached from the lever holding part 18 of the mounting bracket 11, the alarm device 1c of the operation switch part 1 and the alarm part 10 provided in the control part 2 are activated as described above.
sound.

Note that 19 is a signal line connecting the operation switch section 1 and the control section 2.

When the operation switch section 1 is removed or replaced for repair or the like, it is inconvenient for the alarm device 1c and the alarm section 10 to sound.

For this reason, the control unit 2 is provided with a release switch 21 that cancels the sounding of the alarm device 1c and the alarm unit 10. By pressing this switch 21, the microcomputer 20 is activated because the operation switch unit 1 is removed. Even if there is a change in the conduction state of the contacts of the switch 12a, this signal will not be ignored and the alarm device 1c or the alarm unit 10 will not sound.

Additionally, if the operating switch section 1 is removed from the wall surface 13 due to mischief or malicious intent, the alarm device 1c and the alarm section 10 will sound to notify family members and neighbors, but if this sound lasts longer than necessary, it will cause trouble to the neighbors. will be multiplied by Particularly when a family member is out of the house, the electric lock 3 is locked by the above-described operation, and it is difficult to stop the alarm sound from outside the house.

Therefore, if the ringing time is set in advance in the program of the microcomputer 20, the operating switch section 1
The person who tries to remove the alarm will be startled by the alarm and run away, so the intended purpose has been achieved, and the alarm will stop ringing at the set time, so there will be no nuisance to the neighbors.

FIG. 4 is a flow chart of the electric lock of the present invention, and the operation of the control unit according to the present invention will be explained based on the flow chart of FIG.

is input. Therefore, if there is such a signal, the process proceeds to step S2, but if not, the process returns to the previous step.

(2) In step S2, it is checked whether there is an input to the release switch 21 built in the control section 2.
If the input is YES, that is, the release switch is pressed to cancel the sounding of the alarm, the process proceeds to step S4, and if the input to the release switch 21 is NO, that is, there is no cancellation instruction, the process proceeds to step S3.

In step S3, the alarm device 1c of the operation switch section 1 is sounded, and at the same time, the alarm device 1c is activated.
In S5, the alarm section 10 of the control section 2 is made to sound.

(3) In step S6, the microcomputer 20 checks whether the electric lock 3 is locked or unlocked, and if it is unlocked, it immediately proceeds to step S7 and the microcomputer 20 checks whether the electric lock 3 is locked or unlocked.
0 sends a locking signal and locks the electric lock 3.

(4) If the electric lock 3 is not unlocked in step S6, proceed to step S8 and start counting the ringing time, and when the arbitrary set time has elapsed, proceed to step S9 and turn off the alarm device 1.
The microcomputer 20 outputs a signal to stop the c sound.

At about the same time, the microcomputer 20 proceeds to step S10, outputs a signal to stop the alarm section 10 of the control section 2, and returns to the main routine.

(5) When removing the operation switch part 1 for repair or replacement, the release switch 21 is pressed, so proceed to step S4 and remove the micro switch 1 again.
The presence or absence of a signal from micro switch 2a is checked, and if there is no signal, the process returns to step S1, and even if there is a signal from micro switch 12a, the release switch 21 has been pressed.
The program skips steps S3 to S10 and returns to the main routine (step S4).
