Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a control device such as a remote controller that performs initial reset control of a lighting fixture by initially resetting a flip-flop when a commercial alternating current is restored.

Conventionally, for example, a remote control control device that receives a transmitted control code signal and controls the operation of a controlled device such as a lighting fixture using a control pulse signal based on identification of the received control code signal is shown in FIG. As shown, a high-level control pulse signal, that is, a high-level signal, via a receiving section (not shown) is input to the preset terminal PRi of the D-type input flip-flop FFi via the first input terminal _I1 . Furthermore, a high level set signal for initial setting of the input flip-flop FFi via the receiving section is sent to the second input terminal.
_I2 is input to the NOR gate _G1 of the monostable multivibrator circuit M, and the NOR gate
The output of G ₁ is sent to the first inverter G ₂ via the first capacitor C ₁ for charging/discharging and the first resistor R ₁ for time constant.
is input. Note that direct current obtained by converting commercial alternating current is supplied to the receiving section via the power terminal + ^B , the collector and emitter of the first NPN transistor Tr ₁ , and the voltage at the base of the first transistor Tr ₁ is supplied to the third The resistor R ₃ is stabilized by the Zener diode ZD, and the first capacitor C ₁ , the first
A connection point of the resistor R ₁ is connected to the emitter of the first transistor Tr ₁ via a second resistor R ₂ .

Then, the output signal of the monostable multivibrator M, that is, the inverted set signal from the first inverter _G1 , is input to the clear terminal CLi of the input flip-flop FFi.
After being reset, a high level signal is input to the input flip-flop FFi, and at this time, since the input terminal Di and clock terminal CPi of the input flip-flop FFi are grounded, the input flip-flop FFi enters the preset state, and the input flip-flop FFi enters the preset state. A high level signal is output from the Q output terminal Qi of FFi. Note that i is the output terminal of the input flip-flop FFi.

The high level signal from the Q output terminal Qi of the input flip-flop FFi is input to the clock terminal CPo of the D-type output flip-flop FFo, and the preset terminal PRo of the output flip-flop FFo is grounded.
Before the input terminal Do and the output terminal o are connected and a high level signal is input to the clock terminal CPo, the input terminal Do and the output terminal o are held at a high level. They are latched at the same time and a high level signal is output to the Q output terminal.
At this time, the output terminal o of the output flip-flop FFo becomes low level and the input terminal Do becomes low level, and even when no high level signal is input, the Q output terminal Qo goes high. It is held at the same level and continues to output a high level signal. That is, a high level signal, that is, a control pulse signal, is held by the output flip-flop FFo.

Furthermore, the high level signal from the Q output terminal Qo of the output flip-flop FFo is input to the base of the second NPN transistor Tr ₂ via the fourth resistor R ₄ , turning on the second transistor Tr 2 and turning on the second transistor Tr ₂ . When the second transistor _Tr2 is turned on, direct current from the power supply terminal + ^B flows to the second transistor _Tr2 via the relay coil Ry, the relay coil Ry operates, and the operation of the controlled device (not shown) is controlled. For example, a lighting fixture, which is a controlled device, is controlled to be turned on.

Note that both flip-flops FFi and FFo are provided in one integrated circuit IC, and the power supply terminal b of the integrated circuit IC is connected to the emitter of the first transistor _Tr1 , and the ground terminal e is grounded. FFo is driven by direct current via the first transistor _Tr1 . Further, the direct current via the first transistor Tr ₁ is supplied to the series circuit of the fifth resistor R ₅ and the second capacitor C 2 , and the second capacitor C ₂ is connected to the second capacitor C 2 .
By charging C ₂ , the fifth resistor R ₅ and the second capacitor C ₂
The voltage at the connection point, that is, point P, is held at a high level, and the voltage at point P is applied to the second inverter _G3 provided between point P and the clear terminal CLo of the output flip-flop FFo. entered,
Since the output voltage of the second inverter _G3 is at a low level while the commercial alternating current is being applied, the output flip-flop FFo is not reset.

However, commercial AC power outages or momentary interruptions,
When the direct current from the power supply terminal + ^B is cut off, the driving of both flip-flops FFi and FFo is stopped, the output flip-flop FFo stops holding the high level signal, and the output from the Q output terminal Qo of the output flip-flop FFo stops. The high level signal of
The Q output terminal Qo becomes low level, the second transistor Tr ₂ is turned off, and the direct current to the relay coil Ry is immediately cut off, and the operation control of the controlled device is canceled. For example, the controlled device, a lighting fixture, The light goes off. Also, the second capacitor _C2 is discharged.

Next, when the commercial AC recovers from the aforementioned power outage and instantaneous interruption and DC is supplied to the power supply terminal + ^B , driving of both flip-flops FFi and FFo resumes, and charging of the second capacitor _C2 begins. ,
Until the second capacitor _C2 is charged, that is, the time determined by the time constant of the fifth resistor _R5 and the second capacitor _C2 , the voltage at point P is held at a low level, so the second inverter A high-level clear signal, that is, a reset signal, is output from _G2 , and the reset signal causes the output flip-flop FFo to be reset to its initial state. The light continues to go out under the control of Celit.

Therefore, in the event of a power outage or momentary interruption of commercial AC power, the initial reset control will ensure that the lighting fixtures remain off after the power is restored.
Safety is ensured when a momentary power outage occurs.

However, during normal use, for example, when used at home, the control pulse signal must be transmitted again to bring the lighting state before the power outage or instantaneous power outage upon recovery, which poses a problem that requires complicated operations.

This invention has been made with the above-mentioned points in mind, and next, this invention will be explained in detail with reference to FIG. 2 showing one embodiment thereof.

In FIG. 2, the same symbols as in FIG. 1 indicate the same things, and the difference from FIG. ₁ is that the first transistor Tr A rectifier diode D is provided which is biased in the forward direction by direct current from the emitter of ₁ , and the positive electrode of a power supply battery BY consisting of a secondary battery is connected to the power supply terminal b, and further,
Second inverter _G3 and output flip-flop
The sixth resistor is provided between the FFo clear terminal CLo and a switch SW is provided between the clear terminal CLo and the ground point.

When the commercial AC power is turned on, the power terminal + ^B
For example, 12 volts DC is supplied to the battery BY and the integrated circuit IC through the diode D, and the battery BY
is charged and both flip-flops FFi,
FFo is driven.

Next, when the Q output terminal Qo of the output flip-flop FFo becomes high level and the output flip-flop FFo is holding the control pulse signal, that is, the high level signal, if there is a power outage or momentary interruption of the commercial AC. , integrated circuit IC from batteries BY
Since DC continues to be supplied to the output flip-flop FFo, the output flip-flop FFo continues to maintain a high level signal, and the Q output terminal Qo of the output flip-flop FFo continues to maintain a high level signal.

If the switch SW is closed in advance and the clear terminal CLo of the output flip-flop FFo is held at a low level to prevent initial reset, the commercial AC power outage and instantaneous interruption will be restored.
When the commercial AC is turned on again and DC is applied to the source terminal + ^B , the reset signal from the second inverter _G3 caused by charging the second capacitor _C2 is cut off by the switch SW, so the output is The output flip-flop FFo continues to hold the high level signal before the power outage or instantaneous interruption, the Q output terminal Qo of the output flip-flop FFo maintains the high level, the relay coil Ry is driven again, and the controlled equipment The control is resumed to the previous state, and, for example, a lighting fixture, which is a controlled device, is turned on.

On the other hand, if you open the switch SW in advance and set it to perform an initial reset, when the commercial AC recovers from a power outage or momentary interruption, the second capacitor
A reset signal from the second inverter _C3 due to the charging of _C2 is input to the clear terminal CLo of the output flip-flop FFo through the sixth resistor _R6 , and the output flip-flop FFo is reset to maintain the high level signal. At the same time, the Q output terminal Qo of the output flip-flop FFo becomes low level, the second transistor Tr ₂ is turned off, the relay coil Ry is not driven, and the control of the controlled device is stopped. A certain light fixture keeps going off.

Therefore, according to the above embodiment, even in the event of a power outage or instantaneous interruption of commercial AC due to power outage backup of the battery BY, the output flip-flop FFo continues to hold the control pulse signal input before the power outage or instantaneous interruption. .

Then, by opening and closing the switch SW, the setting is normally made so that the initial reset is not performed, and after recovery, the lighting equipment is automatically controlled to the same state (on or off) as before the power outage or instantaneous power outage, improving operability. , when you go out, you can set the lighting equipment to initial reset, and after returning to the home, you can control the lighting equipment to the initial reset state (off) to ensure safety.Remote control of lighting equipment with high operability and safety. equipment can be provided.

Note that, of course, a primary battery can be used as the battery BY.

As described above, this invention uses a flip-flop that operates on a DC power source converted from commercial AC and is initially reset when the commercial AC is turned on to latch the input control pulse signal, and uses the output signal of the flip-flop to control the lighting equipment. A control device for controlling a controlled device such as the above, comprising: a power supply battery that supplies power to the flip-flop during a power outage or instantaneous interruption of the commercial alternating current, and whether or not the initial reset is performed when the commercial alternating current is restored by operation. The present invention provides a control device equipped with a switch for switching between the two modes.

Therefore, according to the control device of this invention, during a commercial AC power outage or instantaneous interruption, direct current from the power battery is supplied to the flip-flop to maintain the control pulse signal before the power outage or instantaneous interruption. By operating a switch, it is possible to select whether or not to perform an initial reset of the flip-flop at the time of recovery, so that the control of controlled devices such as remote control lighting equipment, which conventionally always requires an initial reset, can be changed from the initial reset. It is possible to switch between the control and the control before a power outage or momentary power outage. For example, it is normally set not to perform an initial reset, and after recovery, the lighting equipment is automatically set to the same state (on or off) as it was before the power outage or instantaneous power outage. ) to improve operability, and when you go out, you can set it to initial reset, and after you return, you can control the lighting equipment to the initial reset state (off) to ensure safety. , it is possible to provide a highly safe remote control device for lighting equipment.
