Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device having a novel function, and is particularly suitable for remote control of lighting equipment. And it relates to the improvement of Japanese Patent Application No. 62-250142.

2. Description of the Related Art Conventionally, a remote control device in which an illumination state is selected by a transmitter that transmits infrared rays or the like is known.

Further, a technique for changing the lighting state of the lighting equipment in the system of the wall switch from the first lighting state to the second lighting state including the unlit state by shutting off the wall switch in the room for a predetermined time is Japanese Patent Publication No. No. 7277.

Problems to be Solved by the Invention In the case of the former case, it is inconvenient that the lighting fixture itself cannot be turned on unless there is a transmitter that is easy to lose unless it is equipped with a lighting switch that has the same function as the operation by the transmitter. was there. That is, it is well known that it is very inconvenient because, for example, if you turn off a lighting device with a transmitter when you go out and you want to turn on the lighting device when you go home, you have to find the transmitter in a pitch-black room. On the street. Even if the lighting device itself has a lighting switch, it is not easy to find it in a pitch-dark room.

Also, in the latter case, the lighting fixture can be turned on by simply closing the wall switch, etc., and the purpose is only to change the lighting state after the lighting fixture is turned on once, and remote control is also used. Since the lighting device is not turned on, if the lighting device is turned off by the remote control signal, it is completely out of mind that the lighting device can be turned on. That is, when the lighting equipment is turned off by the remote control signal, it is turned off with the wall switch and the like kept closed. Therefore, the fact that the lighting device can be turned on cannot be conceived by the latter technique that the lighting device can be turned on by simply closing the wall switch or the like.

Therefore, the present invention provides a remote control device having a new function that can put a lighting device or the like in a lighting state (operating state) when the load is turned off (inoperative state) by a remote control signal. With the goal. Another object is to prevent the load from being activated without knowing it after a power failure or the like.

Means for Solving the Problems According to a first aspect of the present invention, a load, a reception control circuit having a load state selection circuit for selectively controlling the load to be in an operating state or a non-operating state by receiving a remote control signal in a receiving section, and a power supply. A power cutoff detection circuit that detects a cutoff, a means that controls the load to an operating state by cutting the power supply within a predetermined time when the load is deactivated by a remote control signal, and the load is deactivated by a remote control signal. A remote control device comprising: a self-maintaining means for self-maintaining the load in the state before the interruption by shutting off the power supply for a predetermined time when the state is set.

According to a second aspect of the present invention, a load, a reception control circuit having a load state selection circuit that selectively controls the load to be in an operating state or a non-operating state by receiving a remote control signal in a receiving section, and a power cutoff detection that detects a power cutoff. A circuit, a means for controlling the load to an operating state by shutting off the power supply within a predetermined time when the load is deactivated by a remote control signal, and a power supply when the load is deactivated by a remote control signal. And a means for controlling the load to an inactive state by shutting off the power after a predetermined time.

According to a third aspect of the present invention, in the first or second aspect, when the load is deactivated by the remote control signal, the load is self-maintained in the state before the interruption by shutting off the power within a second predetermined time shorter than the predetermined time. The remote control device is provided with a self-holding means.

According to claim 1, the state of the load can be selectively controlled by the remote control, and when the load is deactivated by the remote control signal, even if the transmitter for the remote control is not found, the wall switch is activated. The load can be controlled to the operating state by a special operation of shutting off the power supply within a predetermined time, such as once opening and closing the same within a predetermined time. Further, when the load is deactivated by the remote control signal, the load is self-maintained in the state before the interruption (that is, inoperative state in this case) by shutting off the power for a predetermined time (more than a predetermined time). Since self-maintaining means is provided, there is no possibility that the load will remain inactive after power recovery in the event of a normal power failure, and there will be no unintended state in which the load suddenly becomes operational. There is no danger that the load is operating without your knowledge.

According to the second aspect, when the load is deactivated by the remote control signal, the same operation as that of the first aspect is performed.

According to claim 3, when the load is deactivated by the remote control signal, the state of the load does not change after a very short interruption of the power supply such as a momentary power failure, that is, the load is deactivated. Since it is held as it is, there is no possibility of an unintentional state in which it is unexpectedly activated.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

Embodiment 1 (see FIGS. 1 to 3) FIG. 1 is a circuit diagram according to this embodiment, in which a light source (load) including a lamp L and a miniature ball M is connected to a power source AC via a wall switch KSW in a room. Connected. A reception control circuit RX surrounded by a dotted line in the lower half of the figure is controlled by a transmitter (not shown) that transmits a remote control signal RC such as infrared rays. The remote control signal RC from the oscillator is received by the receiving unit M1 in the reception control circuit RX, and the subsequent load state selection circuit SS selectively controls the load to be in the activated or deactivated state. The output of the receiving unit M1 is applied as a remote control signal input to the SIG terminal of the control unit IC1 composed of the IC in the load state selection circuit SS. Although the function of the control unit IC1 will be described later, the transistor Q2, the relay RY1 and the transistor Q3, the relay RY2 are respectively controlled by the control signals generated at the outputs P1 and P2, and the corresponding relay contacts ry1 and ry2 are controlled to be opened and closed. As a result, the lamp L and the miniature ball M are each controlled to open and close.

Next, the DC power supply circuit for supplying the DC power supply to the reception control circuit RX will be described with reference to the upper half of the figure. The power supply AC is stepped down by the transformer T via the wall switch KSW and the rectifier BR.
After performing full-wave rectification with and smoothing with a capacitor C2 via a diode D2, a DC power supply unit DC composed of a constant voltage circuit surrounded by a dotted line makes a constant voltage. The smoothed voltage V _B of the capacitor C2 is supplied to the relays RY1 and RY2 circuits controlled by the transistors Q2 and Q3, respectively, and the output voltage V _C of the DC power supply unit DC is a circuit other than the relay circuit in the reception control circuit RX. Is supplied to.

Next, the power cutoff detection circuit DS that detects the cutoff of the power supply AC
Uses the rectified pulsating voltage of the rectifier BR before entering the diode D2, which is connected to the resistors R1 and R via the diode D1.
An example is shown in which two serial circuits are connected in series. And
The divided voltage of the resistors R1 and R2 is connected to the set input SET of the control unit IC1.

Next, the operation of this embodiment will be described with reference to FIGS. 2 and 3.

Now, the wall switch KSW is turned on at time t ₁ , and then the remote control signal a from the transmitter (not shown) is applied to the terminal S of the control unit IC1.
When entering IG, the code determining means 2 determines the code of the signal a via the input means 1 of the control unit IC1, and the output state forming means (in this example, the signal a is a signal for lighting the lamp L). 3 is a latch type for holding the output state), and the output P1 is set at L level via the output means 4.
A control signal whose level and output P2 are H level is transmitted.
These signals control the relays RY1 and RY2 respectively through the transistors Q2 and Q3, the relay RY1 is turned on, the relay RY2 is turned off, and the relay contact ry of the relay RY1 is
Control so that 1 is closed and relay ry2 of relay RY2 is opened. Therefore, only the lamp L is turned on at the time t ₂ .

Next, when a remote control signal b for lighting the miniature ball M is applied to the terminal SIG of the control unit IC1 from a transmitter (not shown), signal processing is performed according to the above, and the output P1 of the control unit IC1 is at the H level. , P2 is sent out as a control signal.
In this case, relay contact ry1 is open and relay contact r
y2 is in the closed, only Mamedama M is turned on at time t _3.

Next, when the wall switch KSW is turned off at time t ₄ in this state, the miniature ball M is turned off. However, since the control unit IC1 is backed up by the self-power source BAT composed of a battery or a large-capacity capacitor or the like, the outputs P1 and P2 are maintained in the previous state. Therefore, when the wall switch KSW time t _a from the time t ₄ (t _a, for example to 1.5 seconds or more) is turned on again after elapse i.e. time t ₅ of the ones Mamedama M is illuminated.

Then, from the transmitter (not shown), the remote control signal c for the off enters the terminal SIG of to the control unit IC1 arrival, internally as its output P1, P2 are both at the H level at time t ₆ Signal processed. In this case, both relays RY1 and RY2 are turned off, and neither lamp L nor miniature ball M is turned on.

Then, in this state, the operation of turning on the lamp L without operating a transmitter (not shown) will be described below.

To turn on the lamp L, the wall switch KSW is once turned off at time t ₇ and after a time t _b (t _b is within 1.5 seconds, for example), that is, it is turned on again at time t ₈ . It is possible. Explaining the circuit operation by this operation, by turning off the wall switch KSW at time t _{7, the} power supply AC is cut off, the rectified pulsating current voltage applied to the set input SET of the control unit IC1 disappears, and the set The time determination means 6 starts to function through the set input determination means 5 that determines that there is no input. The time determination means 6 is composed of, for example, a timer means, a counter means, etc., and a power cutoff detection signal (in this case, a set input) of the power cutoff detection circuit DS.
(Signal that there is no rectified pulsating voltage that was added to SET)
Of time t _b is determined, and this time is within a predetermined time (for example, 1.5
Within the second), a signal for latching the output state forming means 3 in a predetermined state is sent. As a result, the output P1 is L
The level and the output P2 are held at the H level, the relay RY1 is turned on, and the lamp L is turned on. In this way, the time determination means 6 selectively controls the load state selection circuit SS to the operating state of the load (in this case, the lamp L), so that the wall switch KSW can be shut off within a predetermined time even if the transmitter is not found. The load can be activated by. That is, there is shown means for controlling the load to the operating state by shutting off the power supply AC within a predetermined time when the load is deactivated by the remote control signal RC.

When the time of the power cutoff detection signal of the power cutoff detection circuit DS (the signal input to the set input SET of the control unit IC1) is outside the predetermined time, that is, when the power supply AC is cut off outside the predetermined time, No signal is sent to the output state forming means 3, and in this case, as described above, the load is self-maintained in the state before the interruption. That is, when the load is deactivated by the remote control signal RC, self-maintaining means for self-maintaining the load to the state before the interruption (that is, inoperative state in this case) by shutting off the power supply AC for a predetermined time. Is shown.

Next, other functions that the time determination means 6 is better equipped with will be described.

Generally, a so-called momentary power failure may occur depending on the power supply situation. This momentary power failure is normally within a time of about 0.5 seconds, and the momentary power failure causes the time determination means 6 to function and forcibly turn on the lamp L. Therefore, the time determination means 6 is preferably set so as not to send a signal to the output state forming means 3 when the power supply AC is shut off within the second predetermined time (for example, about 0.5 seconds) shorter than the predetermined time described above. . Then, in the case of the interruption within such a very short second predetermined time, the self-holding means for holding the load in the state before the interruption functions. In this embodiment, the self-holding means involves the DC power supply unit DC that supplies DC power to the reception control circuit RX other than the relay circuit. That is, since this DC power supply unit DC holds the voltage before shutting off or a voltage close to this for a while after the power source AC is shut off, the time until the power source AC is turned on again is the second.
If the time is shorter than the predetermined time, the time determination means 6 does not function, and the reception control circuit RX other than the relay circuit is kept in the state before being cut off. It will be kept in the state of. That is, when the load is deactivated by the remote control signal RC, the state before the load is cut off by cutting off the power supply AC within the second predetermined time shorter than the predetermined time (that is,
In this case, self-holding means for self-holding in the inoperative state) are shown.

 Next, another additional function of the control unit IC1 will be described.

First, the mode setting means 7 is set according to the number of loads or whether the remote control signal input code is one type or a plurality of types. The mode setting input terminal MODE (with five inputs) is set to L or H level, respectively. It is set by giving a signal in advance.

Next, to the switch input terminal SW, a switch signal input suitable for an operation signal from the pull cord type manual switch PSW is added. The switch PSW is, for example, a normally closed type, and the switch input SW is normally at the L level, but when the switch PSW is opened by pulling the pull cord, an H level signal is input to the switch input SW via the resistor R11. Then, the output state forming means 3 is changed to the next output state via the input determining means 8 and the chattering avoiding means 9, and the operating state of the load is sequentially performed in a sequential cycle of lighting the lamp L → lighting the miniature ball M → turning off. Can be changed.

In the clock generating means 10, the crystal X1 is connected to the clock input CLOCK, and the entire control unit IC1 is start-stop controlled by a clock signal having an appropriate frequency.

The connection point between the resistor R8 and the capacitor C6 is connected to the reset input RESET of the reset means 11, and one end of the resistor R8 is connected to the self-power source BAT. This circuit function is self-powered BAT
If it is a battery, reset input when connecting this for the first time
Utilizing the gradual rise of the input voltage of RESET, the control unit IC1 is set to the initial state, the outputs P1 and P2 are set to the H level, and the load is deactivated. Even when the self-power source BAT is a large-capacity capacitor, the control unit IC1 is initialized only when the wall switch KSW is first turned on.

And, in the circuit without self-power supply BAT, it is not possible to maintain the load in the state before the power is cut off after the power supply AC is cut off for a predetermined time, and after the wall switch KSW is turned on again, the reset input RESET The rise is delayed, the control unit IC1 is initialized, and the load is deactivated.
Even such a configuration is not unsuitable for commercialization. That is, there is shown means for controlling the load to the inactive state by shutting off the power supply AC for a predetermined time when the load is inactivated by the remote control signal RC.

Note that the sounding body is driven through the buzzer output means 12 only when the sounding body such as the buzzer BZR is connected to the buzzer output BZ of the control unit IC1 and the state of the output state forming means 3 changes.

Example 2 (see FIGS. 4, 5, and 2) This example differs from Example 1 in the following points.

The output state forming means 3 of the control unit IC1 is not a latch type but a temporary displacement output type, and its outputs P1, P2 and P
3 is a transistor Q2, relay RY1 and transistor Q2 via a mutual reset unit IC2 which is a latch type IC.
3, Connected to relay RY2 respectively. Then, the mutual reset unit IC2 is backed up by the self power supply BAT. This is because it is advantageous to back up the simple mutual reset unit IC2, which has a configuration that can reduce the current consumption when the current consumption is considerably large due to the multifunctionalization of the control unit IC1. is there.

The operation is as shown in the time chart of FIG. 5, the load control function is the same as that of the first embodiment, and the time t _{1 to} t ₈ and the time t.
_{The a} , t _b and the remote control signals a, b, c are under the same conditions as in FIG. In this embodiment, as described above, the control unit IC
A signal that is temporarily displaced to the L level is sent to one of the outputs P1, P2, and P3 of 1 and the mutual reset unit is generated in response to the signal.
Outputs T1, T2, T3 of IC2 are reset mutually. After the wall switch KSW is turned off at time t ₄ , the mutual reset unit
The output T1 of the IC2 is at the H level for a while because the voltage V _C of the DC power supply unit DC is maintained for a while.
Then, to return again to the H level at time t ₅ after a time t _a elapsed is because the mutual resetting unit IC2 is self-sustained by self-powered BAT. Also, the output P of the control unit IC1
3 outputs an L level signal for extinguishing, so that the outputs T1 and T2 of the mutual reset unit IC2 are both latched at H level.

Without self-power supply BAT, reset input RES of control unit IC1 is required when power is turned on again after AC power is cut off for a predetermined time.
The control unit IC1 is initialized by the signal entering ET, and the output P1,
P2 becomes H level and output P3 becomes L level temporarily. Even such a configuration is not unsuitable for commercialization. That is, also here, means for controlling the load to the inactive state by shutting off the power supply AC for a predetermined time when the load is inactivated by the remote control signal RC is shown.

Example 3 (see FIGS. 6, 7, and 2) This example differs from Example 1 in the following points.

The output state forming means 3 of the control unit IC1 is not a latch type but a temporary displacement output type and has three outputs P1 and P1.
2 and P3, the output P1 is connected to the transistor Q2 via the inverting gate INV1, and the output P2 is connected to the transistor Q4 via the inverting gate INV2. Also, the outputs P2, P3 are connected to the transistor Q3 via the NAND gate NA1, and the outputs P1, P3
Is connected to transistor Q5 via NAND gate NA2. The transistors Q2 and Q3 are connected to the two-winding latch type relay RY1, and the transistors Q4 and Q5 are connected to the two-winding latch type relay RY2. Also, relay R like this
Since Y1 and RY2 are of the latch type, a self-power source for backing up the control unit IC1 is not necessary.

The operation is as shown in the time chart of FIG. 7, the load control function is the same as that of the first embodiment, and the time t _{1 to} t ₈ and the time t.
_{The a} , t _b and the remote control signals a, b, c are under the same conditions as in FIG. In this embodiment, as described above, the control unit IC
A signal that is temporarily displaced to the L level is sent to the outputs P1, P2, and P3 of 1 and the relays RY1 and RY2 are latched according to the signal. Incidentally, after being turned off wall switch KSW at time t _4, the output P1, P2, P3 that is while the H level, the voltage V _C of the DC power supply DC is because remaining while. Then, the wall switch at time t ₅ after the elapse of the time t _a
When KSW is turned on again, the reset input RESET of control unit IC1
The control signal IC1 is initialized by a reset signal applied to the outputs P1, P2, P3 to the H level. Since this H level signal is added to the bases of the transistors Q2 to Q5 as an L level signal, it does not cause collector current to flow through these transistors Q2 to Q5. Therefore, the relays RY1 and RY2 are in the state before being cut off. It is self-maintained, and the miniature ball M is lit as in the previous state.

A circuit in which a single-winding latch relay is used for the relays RY1 and RY2 and a reverse current is alternately applied to the coils to alternately perform the latch operation is also conceivable.

Fourth Embodiment (See FIG. 8) This embodiment shows another embodiment of the power cutoff detection circuit DS of the first embodiment. This power cutoff detection circuit DS is a photocoupler.
A PC is used, and the light emitting diode LED inside is connected to the secondary side (may be the primary side) of the transformer T, and the output voltage V _C of the DC power supply unit DC is supplied to the collector of the phototransistor PTR for light reception. The emitter is connected to the common line via the resistor R19. The emitter of the phototransistor PTR is connected to the set input SET of the control unit IC1, and when the power supply AC is cut off, the input signal of the set input SET becomes L level. The operation of this embodiment is the same as that of the first embodiment.

The load control states according to the preferred embodiment described above are summarized in the following table.

It is suitable that the predetermined time is about 1 to 2 seconds and the second predetermined time is about 0.1 to 0.5 seconds.

Further, all or a main part of the control unit IC1 may be made into a microcomputer, and there may be a degree of freedom in setting the function by software, and for example, a predetermined time and a second predetermined time can be freely set. .

As a modification common to all the embodiments, a so-called dimming state by a dimmer may be adopted as the operating state of the load, and a semiconductor switch means such as a triac may be used instead of the relays RY1 and RY2. You may use.

Finally, the load control state according to the present invention is summarized as shown in FIG.

EFFECTS OF THE INVENTION According to claim 1, the state of the load can be selectively controlled by the remote control, and when the load is deactivated by the remote control signal, even if the transmitter for the remote control is not found, the wall Since the load can be controlled to the operating state by a special operation of opening the switch etc. and closing it within a predetermined time within a predetermined time, the load can be operated even if there is no transmitter that is often lost It is very convenient to use, and has a very useful application for remote control of lighting equipment. Further, when the load is deactivated by the remote control signal, the self-maintaining means for self-maintaining the load to the state before the interruption (that is, the inoperative state in this case) by shutting off the power supply for a predetermined time is provided. Therefore, there is no risk that the load will remain inactive after power is restored in the event of a normal power failure, resulting in an unintended state of unexpected activation.For example, if a power failure occurs during absence, There is no fear that it is working without your knowledge.

According to the second aspect, when the load is inactivated by the remote control signal, the same effect as that of the first aspect is obtained.

According to claim 3, when the load is deactivated by the remote control signal, the state of the load does not change after a very short interruption of the power supply such as a momentary power failure, that is, the load is deactivated. Since it is held as it is, there is no possibility of an unintentional state in which it is unexpectedly activated.
