Description

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

A conventional remote control device for a lighting lamp includes a lighting lamp, a transmitter that emits light and electromagnetic waves such as 4 waves, and a control circuit that receives the electromagnetic waves from the transmitter and turns on or off the lighting lamp. The control circuit for this type of optical technology selects electromagnetic waves as the medium, so it will not turn on the lighting even when it receives electromagnetic waves from sources other than the transmitter. Turning the light on or off, that is, it malfunctions.To prevent such malfunctions, the control circuit must be installed so that it does not receive electromagnetic waves from sources other than the transmitter, or the control circuit must be installed so that it does not receive electromagnetic waves from sources other than the transmitter. It was necessary to provide a discrimination circuit to determine whether the electromagnetic waves were coming from a source other than the transmitter, which made the circuit complex.Also, when radio waves were selected as the medium, the radio waves from the transmitter interfered with wireless communications.

The purpose of the invention is to solve the above-mentioned technical problems and to remotely control illumination lights using ultrasound as a medium? An object of the present invention is to provide an MJ device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

, 1 is a block circuit diagram of an embodiment of the present invention. The remote control device l according to the present invention includes a lighting lamp 2, a transmitter 3
and a control circuit 4. The illumination light 2Fi is installed, for example, in a cabin or a passageway of a ship.

The transmitter 3 has an oscillation circuit 5 and an oscillation element 6, and oscillates at a frequency of 1 fl OkHz in the ultrasonic band, which exceeds the audible frequency of the oscillation circuit 5. These include six oscillation elements, a piezoelectric vibrator, an electrostrictive vibrator, a magnetostrictive vibrator, etc., which emit ultrasonic waves as a medium in response to the output from the oscillation circuit 5. The IF power from the punch riff is applied to the oscillation circuit 5 and the amplifier circuit 9 via the switch 8. The battery 7 is one Natoege IL3 battery, the switch 8 can be made from the outside of the casing l() of the transmitter 3, and the casing lO is provided with an electromagnetic shield. Further, the casing 10 is formed into a small size and a shape so as to be easily portable.

This transmitter 3Vi is placed, for example, near each cabin crew member, or is 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 the element 6 to the vibration receiving element 11KIi71 of the control circuit 4. The distance ■E that can energize the control amount 1iF+4 by the transmitter 3 is
For example, lOm.

An astable circuit 46 which is energized by the battery 7 is connected to the terminal that displays the capacity of the electric power stored in the battery 7.

The power consumption of this astable circuit 46 is designed to be negligible. The astable circuit 46 has a predetermined constant period T (T=Ta+Tb) consisting of a slight high-level pulse width Ta and a low-level pulse width Tb.
Derive the signal. The astable circuit 46 includes a light emitting element 47.
For example, a light emitting diode is connected. The light emitting element 47 is pulsed with a period T by a signal from the astable circuit 46.
The light of Ta is turned on for 1 period and then turned off for the period of pulse #1iTb.

If the punch rear capacity is sufficient, the pulse width Ta
The amount of light from the light emitting element 47 during the period is large. Therefore, it is understood that the large amount of light from the light emitting element 47 indicates that the battery 7 has sufficient capacity. 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 is understood that the capacity of the battery 7 is small because the amount of light from the light emitting element 47 is small.

The period of the pulse width Ta is very small, 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 on the battery 7 due to the provision of the astable circuit 46 and the light emitting element 47 is small. Further, by providing the astable circuit 46 and the light emitting element 47, the transmitter 3 can be easily found even if the transmitter 3 is located in the darkness of the cabin. Note that the circuit for displaying the capacity of the battery 7 and the circuit for notifying the placement position of the transmitter 3 have # period pulse widths Ta, Tb according to the voltage of the battery 7 instead of the astable circuit 47. It may be a circuit in which the duty ratio of is changed, 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 lif'i is a piezoelectric vibrator, an electrostrictive vibrator, a magnetostrictive vibrator, etc., like the above-mentioned oscillating element 6, and outputs an electrical signal to the active filter 12 only when receiving an ultrasonic wave. 12 active filters, with amplification function and bandpass function 1-1 Amplify only the predetermined frequency component and convert the frequency-voltage conversion amount FI
Give it to b13. 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 2 and outputs a DC voltage, and this DC voltage is passed through a resistor 14 to an operational amplifier [15
is applied to the non-inverting input of

A capacitor 6 for charging and a resistor 17 for discharging the charge charged in the capacitor 6 are connected between the non-inverting input of the operational amplifier @15 and ground. The inverting input KVi of the operational amplifier 15 is applied with a reference voltage. In other words, the voltage divided by the resistors 18 and 19 is K.
lI: Provided to the inverting input of the amplifier 15. Therefore operational amplifier is#-j.

A high-level signal is given to the toggle flip-flop 2 () during the period when the ultrasonic wave is given from the transmitter 3, and a low-level signal during the other periods.

The toggle 7 lip 70 tube 20 alternately applies signals of different levels from the set output Q to the base of the transistor 21, such as high level → low level → high level, every time a high level signal is applied to the toggle input T. . 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 source and ground, and a diode 25 for the coil 24Ktli surge absorber is connected in parallel with KI#! e will be done. When a high level signal is applied to the toggle flip 70 tube 20 or the transistor 21, the transistor 21 becomes conductive, the coil 24 is excited, and the switch 22 becomes conductive. When a low level signal is applied from the toggle 7 lip flop 20 to the transistor 21, the transistor 21 is quickly turned off, the coil 24 is demagnetized, and the switch 22 is cut off. The switch 22Fi, the lighting lamp 2, and the AC power supply 26 are connected again in a closed loop.

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

In this manner, the illumination lamp 2 is turned on at time t1 as shown in FIG. 2 (2). From time t2 to [3], when the transmitter 3 stops emitting ultrasonic waves as shown in FIG. 2 (1), the output of the operational amplifier 15 becomes low level, but the set output of the toggle flip-flop 2 () Since the QFi is maintained at a high level, the illumination lamp 2 is turned on as shown in FIG. 2 (2). When ultrasonic waves are emitted from the transmitter 3 between times 13 and 14 as shown in FIG. becomes low level. Therefore, Figure 2 (2)
As shown in FIG. 2, the illumination light 2V'i is turned off at time t3. After time t4,! As shown in FIG. 2 il+, when the transmitter 3 stops emitting ultrasonic waves, the output of the operational amplifier 15 becomes low level, but continues to be maintained at the set output cover low level of the toggle flip 7a knob 20. Therefore, the illumination lamp 2 remains off until the next time the transmitter 3 emits an ultrasonic wave.

What should be noted is that the control circuit 42 of the remote control device a-4-1 is configured to cause the illumination light 2 to repeatedly turn on and off when the switch 8 of the transmitter 3 is pressed multiple times within a short period of time. An intermediate stability circuit 43 is provided to prevent this. When a high level signal is applied, the monostable circuit 43 derives a high level signal 8 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 70 knob 2 is output.
