Therefore, the first relay 28, the second relay 30, the reed relay 27, the third relay 32, and the switch transistor 3
The control circuit 6 is composed of three and so on.

Next, the operation of the gate warning device of the present invention will be explained.

First, when the power switch 20 is turned on, the control circuit 6 enters a standby state.

At this time, if the cylindrical lock 13 is not locked, the electric lock 2
The locking piece 2a and the latch of the cylindrical lock 13 are not locked, and the user can enter and exit from the gate 1 by rotating the knob of the cylindrical lock 13.

In this state, the first alarm set switch 8 on the indoor control panel B is now activated.
or the second warning set switch 10a on the outdoor operation panel C;
10b, an excitation current flows through the first winding circuit t1 of the reed relay 27, and the reed relay 27 connects the selector switch r2□ to the b contact (set) side.

Here, when the doors 1a and lb of the gate 1 are opened and the detection switch 3 is turned on, current flows through the changeover switch r22, the second relay 30, the diode 31, and the detection switch 30 circuit, and the second relay 30 is not activated. Relay contact r30a is closed to form a self-holding circuit, and relay contact r30a is closed to form a self-holding circuit.
3oa to short-circuit the alarm control terminals Ic and Id of the alarm 5.

The alarm 5 emits an alarm sound.

In this case, even if the gate 1 is closed again, the alarm will continue to sound until the warning release switch 9 is turned on, since the second relay 30 is still holding its power.

Whether or not the vehicle is in the alert state is indicated by the alert display element 22.16.

Next, when the warning release switch 9 is turned on, an exciting current flows through the second winding circuit t2 of the reed relay 27, and the reed relay 27 connects the changeover switch r2□ to the a contact (
(release) side.

At this time, the warning display elements 16 and 22 are both turned off.

In this released state, R1a of gate 1, 1
When b is opened and the detection switch 3 is turned on, current flows through the circuit of the changeover switch r27, the first relay 28, the diode 29, and the detection switch 3, and the first relay 28 is activated.

When the relay contact r28 of the first relay 28 is closed, the visitor chime control terminals Ia and Ib of the alarm 5 are short-circuited, and the alarm 5 emits a chime sound to notify the visitor.

When going out to the lake, with the alarm release switch 9 turned on, go outside the gate 1 and then turn on the second alarm set switches 10a and 10b on the outdoor operation panel C to set the alarm state.

Next, lock the cylindrical lock 13 and attach the latch to the locking piece 2 of the electric lock 2.
When the door 717 of the outdoor operation panel C is used to announce the arrival of a visitor, the person indoors can release the locking piece of the electric lock 2 by closing the unlock switch 4. 2a can be unlocked from the latch of the cylindrical lock 13.

At this time, the unlocking detection switch 35 provided in the electric lock 2 is turned on and the unlocking display element 23 emits light, and at the same time, the second winding circuit t2 of the reed relay 27 and the unlocking detection switch 3
5 and activates the reed relay 27,
If the changeover switch r27 is on the b contact (set) side, it is switched to the a contact (release) side, and the control circuit 6 is placed in the release state.

When the unlocked gate 1 is pushed from the outside, it becomes freely openable, and a chime sound is emitted from the alarm 5 by the action of the push detection switch 3 which opens the gate 1.

Also, when a family member returns home, if the reciter code that is the same as the code set in the code verification circuit 19 is pressed on the numeric keypad of the keyboard switch 7 of the outdoor operation panel C,
A matching output is generated from the code matching circuit 19, turning on the switching transistor 33, energizing the third relay 32, closing the relay contact r32, and operating the electric lock 2.

When the electric lock 2 is operated and unlocked, the circuit becomes in the same state as the above-mentioned visitor, and the gate 1 can be freely pushed open.

The gate door 1 also includes an entrance, a back door, and a door through which others enter and exit.

As described above, the present invention is composed of a sharp part, an outdoor operation panel, and an indoor operation panel, so that the warning device is made into a unit of each part, and can be installed at each predetermined position extremely easily during construction. It has a detection switch that detects the opening of the gate, and an alarm that is linked to the detection switch and notifies the opening of the gate, so the notification operation is reliable. , a first warning set switch on the indoor operation panel that sets the alarm to a state in which it is possible to send a warning signal;
A warning release switch is provided to release the alarm from a state in which a warning signal can be transmitted and set it to a state in which a visitor signal can be transmitted, and a second warning set switch is provided on the outdoor operation panel to set the alarm to a state in which a warning signal can be transmitted. Therefore, it is possible to easily switch between visiting and warning.
Moreover, if the code signal from the keyboard switch installed on the outdoor operation panel is a predetermined code signal, a control circuit is provided to unlock the electric lock, so the electric lock can be unlocked without using a key. It is possible to enter and exit through the gate, and since it uses a code signal, it is safe from a crime prevention perspective.Furthermore, when the electric lock detects that the electric lock is unlocked, it releases the warning signal from the alarm, allowing it to send a visitor signal. Since the door is equipped with an unlock detection switch that is set to , even if the door is in the guard state, if the electric lock is unlocked, the guard state is automatically switched to the visiting state.
