Description

[Detailed description of the invention] The present invention relates to a remote control device for a lighting lamp.

A conventional remote control device for a lighting lamp includes: - A control circuit that transmits all electromagnetic waves such as lighting, light and radio waves, and receives all electromagnetic waves from a transmitter to turn on or turn off the lighting. It is controlled by electromagnetic waves from the machine. However, since such a control circuit of the prior art selects all electromagnetic waves as a medium, it turns on or off the illumination light even when all electromagnetic waves are received from sources other than the transmitter.

In other words, it malfunctions. To prevent such malfunctions, K installs the control circuit so that it does not receive all electromagnetic waves from sources other than the transmitter, and installs a discriminator in the control circuit to determine whether electromagnetic waves are coming from the transmitter or from outside the transmitter. It was necessary to install a circuit, etc., and the two circuits became confusing. Furthermore, when radio waves were selected as the medium, the radio waves from the transmitter interfered with wireless communications.

Furthermore, it is desirable that the lighting or turning-off state of the illumination lamp be returned to the original lighting or turning-off state even when the power is restored after a power outage. On ships, instantaneous power outages may occur during inspections or when switching power supplies.

An object of the present invention is to solve the above-mentioned technical problems and to provide a remote control device for a lighting lamp that completely uses ultrasonic waves as a medium.

Another object of the present invention is to provide a remote control device for a lighting lamp, which is characterized in that, after the power is restored, the lighting returns to the on or off state before the power outage occurred.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block circuit diagram of an embodiment of the present invention.

A remote control device 1 according to the invention includes a lighting lamp 2, a transmitter 3 and a control circuit 4. Lighting light 2.

For example, they are installed in cabins and passageways of ships.

The transmitter includes a three-digit oscillation circuit 5 and an oscillation element 6, and the oscillation circuit 5 oscillates at a frequency in the ultrasonic band exceeding the audible frequency, for example, 100 KHz. The oscillation element 6 is a piezoelectric vibrator, an electrostrictive vibrator, a magnetostrictive vibrator, or the like that emits ultrasonic waves as a medium in response to the output from the oscillation circuit 5. Power from the vancillier is applied to the oscillation circuit 5 and the amplifier circuit 9 via the switch 8. For example, the banchiria is powered by one AA battery, and the switch 8 is connected to the casing 10 of the transmitter 3.
It can be operated from the outside, and its casing 10 is provided with an electromagnetic shield. Further, the casing 10 is formed to be small and lightweight in order to be easily portable.

This transmitter 3I'i is placed, for example, near the entrance of each cabin or carried by each crew member, and when the crew member suppresses the switch 8, the oscillation element is transmitted through the oscillation circuit 5 and the amplifier circuit 9. Ultrasonic waves are emitted from 6 toward the vibration receiving element 11 of the control circuit 4. The distance over which the control circuit 4 can be energized by the transmitter 3 is, for example, 10 m.

An astable circuit 46 is connected to the battery 7 which is energized by its bunch lift in order to display the full capacity of power remaining in the bunch lily.

This astable circuit 46 is configured to consume negligible power. The astable circuit 46 has a predetermined constant period T (T-Ta+Tb
). A light emitting element 47, for example a light emitting diode, is connected to the astable circuit 46. Light emitting element 4
7, the light is turned on for a period of pulse width T'a with a period T by a signal from the astable circuit 46, and is turned off for a period of pulse width Tb.

If the battery 7 has sufficient capacity, the pulse width Ta
The amount of light emitted from the light emitting element 47 during the period is approximately 100%. Therefore, it is understood that since the amount of light from the light emitting element 47 is equal to that of the light emitting element 47, the capacity of the vantilia is sufficient. When the capacity of the battery 7 decreases, the amount of light from the light emitting element 47 during the period of pulse width Ta is small. Therefore, it can be understood that the small amount of light from the light emitting element 47 means that the capacity of the bunchillar is small.

The period of the pulse width Ta is very short, and accordingly, the power consumption due to lighting of the light emitting element 47 is small.

When the light emitting element 47 is a light emitting diode.

Power consumption due to lighting of the light emitting diode is reduced. Therefore, the burden placed on the bunchillar by providing the astable circuit 46 and the light emitting element 47 is small. Furthermore, by providing the astable circuit 46 and the light emitting element 47,
Even if the transmitter 3 is located in the darkness of the cabin, the transmitter 3 k ffM can be easily found. Note that the astable circuit 47 is replaced by a circuit for displaying the capacity of the battery 7 or a circuit for notifying the position M of the transmitter 3.

The circuit may be such that the duty ratio of the pulse widths Ta and Tb changes depending on the punch riff voltage, or may have other configurations.

The control circuit 4 includes a vibration receiving element 11 that receives ultrasonic waves from the transmitter 3. This vibration receiving element 11 is the above-mentioned oscillation element 6.
Similarly, piezoelectric vibrators and electrostrictive vibrators.

The active filter 121C is a magnetostrictive vibrator, etc., and outputs only one electrical signal when receiving ultrasonic waves. The active filter 12 has an amplification function and a bandpass function, and amplifies only a predetermined frequency component and supplies it to the frequency-voltage conversion circuit 13. That is, only the frequency component corresponding to the ultrasonic wave from the oscillation circuit 5 is given to the frequency-voltage conversion circuit 13.

The frequency-voltage conversion circuit 13 receives the signal from the active filter 12 and outputs the full DC voltage, and this DC voltage is passed through a resistor 14 to an operational amplifier 15 having a level discrimination function.
is applied to the non-inverting input of

A capacitor 16 for charging and a resistor 17 for discharging the charge stored in the capacitor 16 are connected between the non-inverting input of the operational amplifier 15 and ground. For the inverting input of operational amplifier 15.

A reference voltage is provided. That is, the voltage divided by the resistors 18 and 39 is applied to the inverting input of the operational amplifier 15. Therefore, the operational amplifier 15.

A low level signal is applied to the toggle flip-flop 20 during the period when the ultrasonic wave is applied from the transmitter 3, and a low level signal during the other periods.

Each time a high level signal is applied to the toggle input T, the toggle flip-flop 20 applies signals of different levels from the set output Q to the base of the transistor 21, such as from high level to low level to no level. A series circuit consisting of a coil 24 of a relay 23 having a switch 22 and a transistor 21 is connected between the DC power supply and ground, and a diode 25 for a surge absorber is connected in parallel to the coil 24IC. Toggle) When a high level signal is applied from the limp flop 20 to the transistor 21, the transistor 21 becomes conductive, the coil 24 is excited, and the switch 22 becomes conductive. Toggle flip prop 20 to transistor 2
When a low level signal is applied to the transistor 1, the transistor 21 is cut off, the coil 24 is demagnetized, and the switch 22 is cut off. The switch 22 is connected to the lighting lamp 2 and the AC power source 26 in a closed loop.

The casing 27 of the control circuit 4 is also electromagnetically shielded.

Referring to FIG. 2, when illumination light 2 is off,
As shown in FIG. f1), the switch 8 is pressed between times t1 and t2 to emit all ultrasonic waves from the transmitter 3 toward the receiving element 11Vc of the control circuit 4. Then, the output of the operational amplifier 15 becomes high level, and the toggle flip-flop 20
The sensor output Q becomes high level, and transistor 2
1 becomes conductive, the coil 24 is excited, and the switch 22 becomes conductive.

By operating in this way, as shown in FIG. 2 (2), the time t
1, the illumination lamp 2 is turned on. When ultrasonic waves are no longer emitted from the transmitter 3 between times 12 and 13 as shown in FIG.
Therefore, as shown in Figure 2 (2),
), the illumination lamp 2 is lit. Time 13-1
When an ultrasonic wave is emitted from the transmitter 3 as shown in FIG.

The output of the operational amplifier 15 is at a high level, and the output of the toggle flip 70 amplifier 20 is at a low level.

Therefore, as shown in FIG. 2(2), the illumination lamp 2I/'i
, the light goes out at time t3. After time t4,
As shown in FIG. 2+11, when the ultrasonic wave is no longer emitted from the transmitter 3, the output of the operational amplifier 15 becomes a low level, but the set output of the toggle flip-flop 20 continues to be held at a low level. Therefore, the illumination lamp 2 remains off until the ultrasonic wave is emitted from the primary transmitter 3.

The flip-flop 20 is powered by a power supply circuit 50 via a diode 51. Power through diode 51 charges capacitor 52 .

The self-discharge resistance of capacitor 52 is extremely small.

The power supply circuit 50 is supplied with power from a power supply 53, and the output from the power supply circuit 50 that derives DC power energizes all the components included in the control circuit 4. The power consumption of the flip-flop 20 is negligible,
Therefore, the power stored in the capacitor 52 allows the memory state to be maintained by being continuously energized, for example, day and night.

In a normal state without a power outage, the control circuit 4 operates normally with the power from the power supply circuit 50. The storage means 20 stores the lighting and extinguishing states of the illumination lights.

When a power outage occurs, the flip-flop 20 is powered by the power of the capacitor 52, and its stored state is maintained up to -1.

Power from capacitor 52 is not provided to the remaining components by the action of diode 51. Therefore, even if the capacitor 52 has a relatively small capacity, it can maintain the memory of the flip-flop 20 for a long time.

When the power is restored, the relay 23 that responds to the output of the 7-lip flop 20 is returned to the switching state before the power outage by the power from the power supply circuit 50, so that the illumination lamp is turned off as much as it was before the power outage.

It should be noted that the control circuit 32 of the remote control device 31 is equipped with a light emitting element 33 for indicating the position. In this embodiment, relay 23 & coil 24 . of the first illustrated embodiment are used. Instead of switch 22, relay 34. Coil 35. A switch 36 is used respectively.

As shown in FIG. 3, when the transmitter 3 emits ultrasonic waves for a short period of time before time t5, the coil 35 is excited and the common contact 37 and the individual contacts 38 of the switch 36 are connected.
The illumination light 2Fi is turned on at time t5 as shown in FIG. 4 (2).

The light emitting element 33 is turned off as shown in FIG. 4(3).

That is, even in the darkness of a cabin or the like, it is sufficient to press the switch 8 of the transmitter 3 to emit ultrasonic waves toward the light of the light emitting element 33 of the control circuit 32.

A short time after time t6, from transmitter 3 to Figure 4 +11
When the ultrasound is emitted again as shown in .

FIG. 5 is a block circuit diagram of another embodiment of the present invention, in which parts corresponding to the embodiment shown in the first figure are given the same reference numerals. What should be noted is that the control circuit 42 of the remote control device 41 has a monostable function that prevents the lighting lamp 2 from repeatedly turning on and off when the switch 8 of the transmitter 3 is suppressed multiple times within a short period of time. A circuit 43 is provided. When the monostable circuit 43 receives a high level signal, it derives a high level signal for a predetermined period of time W, and even if the next high level signal is further applied within this time W, the toggle flip-flop 20 does not output a high level signal. It can be maintained at a high level without causing reversal. Time W is.

For example, it is preset to 10 seconds.

Referring to FIG. 6, when the switch 8 of the transmitter 3 is pressed twice at a time t8 and a short time later at a time t9 while the illumination light 2 is off, the transmitter 3 as shown in FIG. fi+
Ultrasonic waves are emitted twice as shown in . A high level signal is also applied from the operational amplifier 15 of the control circuit 42 to the monostable circuit 43 twice at time t8 and time t9. As shown in FIG. 6(2), the monostable circuit 43 derives a high-level signal only once from time t8 to time tlO, which exceeds time t9' after W time. Therefore, there are 2 lighting lamps.
.

As shown in FIG. 6(3), the light is turned on at time t8 and continues to be turned on.

When the illumination lamp 2 is on, the switch 8 of the transmitter 3 is activated at a short time interval from time t11 to time t12. t13
When is pressed three times, the transmitter 3 emits ultrasonic waves three times as shown in FIG. 6ftl.

From the operational amplifier 15 of the control circuit 42 to the monostable circuit 43, 1 time tll, t12. 3 high level signals at t13
times are given. The monostable circuit 43 is.

As shown in FIG. 6(2), time t, 12. t13'! Until time t14, which exceeds r, a signal at the no-y level is derived only once. Therefore, lighting lamp 2
The light is turned off at time tll as shown in FIG. 6(3), and continues to be turned off at that time. Therefore switch 8 of transmitter 3
Even if the suppression operation is performed multiple times within a short period of time, illumination light 2 will not turn on.
This prevents the lights from repeatedly turning off. Further, the lighting lamp 2 is prevented from repeatedly turning on and off due to the chattering of the switch 8.

As another embodiment of the present invention, the circuit for preventing the lighting lamp 2 from repeatedly turning on and off even if the switch 8 of the transmitter 3 is suppressed multiple times within a short period of time is not the monostable circuit 43. Alternatively, the circuit may be provided in the transmitter 3. Furthermore, it may be provided in the control circuit 32 of the embodiment shown in the third figure.

As another embodiment of the present invention, a remote control device 1°31.4
1 may be used for anything other than ships. Further, the transmitter 3 and the control circuit 4, 32, 42'ld may have other configurations.

As another embodiment of the present invention, a so-called launching relay may be used instead of the combination of flip-flop 20 and relay 23. The launching relay changes its switching mode in response to the output from the operational amplifier 15,
The switching mode is maintained even after a subsequent input cutoff.

By receiving a new input, it changes its switching behavior and maintains itself.

The transmitter 3 and the control circuits 4, 32, 42 may be provided in an area requiring an explosion-proof structure.

At this time, at least the relay switch 22.3'6 is
It is housed in an explosion-proof case in an explosion-proof area, or installed in an area that does not require an explosion-proof structure.

As described above, according to the present invention, since the medium between the transmitter of the remote control device and the control circuit is ultrasonic waves, malfunctions are prevented. Also, it does not interfere with wireless communications. In addition, ultrasonic waves, such as light, have sharper directivity, so even if the ultrasonic waves from the transmitter do not directly hit the control circuit's receiving element, the control circuit is energized and the operability is improved as much as possible. Improved.

Further, according to the present invention, after the power outage is restored, if the lighting lamp was on before the power outage occurred, it returns to the lighting state,
Furthermore, when the illumination light is off before the power outage occurs, the off state is maintained, so the operability is improved. Especially this.

This is convenient when power outages occur relatively often on ships and the like.
