Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a notification device that is built into, for example, a porch light and detects a visitor and automatically turns on the porch light.

There are currently entrance lights on the market that have a detection function that uses infrared rays and ultrasonic waves to detect the presence of visitors, and automatically turn on when there is a visitor. Since there is no need to turn it on during the day, it is commonly used to turn off the power using a power switch, and turn on the wall switch only at night to activate the device. Therefore, the long-awaited detection function is not used at all during the daytime and is powerless against visitors during the daytime.Therefore, it is necessary to use electricity to detect visitors during the daytime and notify indoor residents. If you try to turn it on, it will turn on even during the day, wasting power.

In addition, since this type of device is a two-wire type, in order to operate only the detection circuit during the day, it is necessary to separately wire the detection circuit only, which is not connected to the lighting. Utilizing the detection function has the disadvantage of requiring extra construction work and expense.

This invention was made with the purpose of solving these inconveniences, and providing an alarm device that does not require extra wiring and can operate only the detection circuit during the daytime. In one half of the cycle, the detection circuit is activated, and in the other half of the cycle, the control circuit that controls the load, such as the lighting, is activated.

Next, an embodiment shown in one figure will be described. In the figure, (
1) is a notification device according to the present invention, and (2) is a wall switch (
3) is the switch box, and (4) is the indoor wiring in the middle.

f5) Fi commercial power supply, 1B) Fi lamps such as entrance lights,
(7) It is an ilt receiver. The wall switch (31K) is connected in parallel with a diode (8) and a bypass capacitor (9), and is connected to the commercial power via the detection circuit (IIFi, diode (8) and diode (6) of the same polarity in the alarm device (1). This allows the commercial type #(5) to supply power to the sensing circuit (to) during the forward half cycle through the diodes (8) and (6), and the sensing circuit (to). IQ is in operation even when the wall switch (3), which connects to the DC power obtained by smoothing it with the internal smoothing capacitor 0, is open.Detector B#i Infrared rays or ultrasonic waves are approaching the IQ. Person aaJk: When the detector (to) detects a person 1141, a signal wave is transmitted from the detection circuit IG, passes through the bypass capacitor (to) (9), and is sent to a remote location IIC receiver (7). ), and the receiver (7) operates to notify that a visitor has arrived.In addition, the transmission of such a notification signal, the conveyance of the signal wave by the indoor wiring (4), and the receiver (7)
) Regarding the reception of signal waves and the notification operation, various methods such as cams have been put into practical use in this type of notification device, and these can be adopted as appropriate, so the details thereof will be omitted.

iml is a load control circuit for the notification device (1), which is a photocoupler (17+ photothyristor II and the coil (to) of relay 11) connected in series to the commercial power source (5).This photothyristor is an asFi diode. (8) The polarity is opposite to that of I and becomes h. When the detector 1 detects a person (14) and a signal wave is transmitted from the detection circuit al, the photocoupler (171) connected to the detection circuit 11 [) Current also flows through the light emitting diode (211VC), and the light emitting diode (2
) will emit light, but since the photothyristor (to) is connected with opposite polarity, no current will flow through the photothyristor in this case. Therefore, the relay fil
does not operate, and the normally open contact @ of relay α9 remains open.

Also, since the diode connected in parallel to the contact (2) has the opposite polarity to the diode (8), the lamp (6) connected to the commercial type i1i (51) in series with the contact does not light up.

Next, when the wall switch (3) is turned on in the evening,
Lamp 16) Ushiwa is lit through the Fi diode (to), and in the dark when there are no visitors, it is dimly lit in a power-saving state. When the visitor's detector (7) detects a person, the receiver (7)
) is activated, and at the same time, the light emitting diode (2) activates the photothyristor (to), so the relay shouting coil mK
Current flows, the contact @ closes, and the lamp (6) lights up brightly with full wave lighting.

With the above configuration, the indoor wiring (4), which is a two-wire wiring to the lamp (6), can be used as is for the power wiring to the alarm device (11), and the conventional lamp can be used as the lamp of this embodiment. All you need to do is replace the attached notification device (1) and add two parts, the diode (8) and the capacitor (9), inside the switch box (2), so no new wiring work is required. can be installed.

Note that the diode @ may be a miniature light bulb, or it may not be added at all, or a #i 1/4 wave lighting circuit may be added. Further, although a relay is used to control the lamp (6), this can also be replaced with a semiconductor element such as a triac.

As is clear from the above description of the embodiments, the present invention operates the detection circuit in one half cycle by connecting the detection circuit to an AC power source via a rectification element such as a diode, and the rectification element By connecting the load control circuit to the above AC '4# through a rectifying element of opposite polarity,
The load control circuit is activated during the other half cycle, and can be applied not only to the entrance light shown in the example, but also to various self-produced devices that also serve as notifications, and these devices can be installed. In this case, there is no need to provide power supply wiring for the notification device separately from power supply wiring for the automatic operation equipment, and there is an advantage that installation work can be performed easily and at low cost.
