Description

  The present invention relates to a lighting control system that controls a plurality of lighting loads by wireless signals.

Conventionally, as an illumination control system having a plurality of illumination devices each having an illumination load and controlling the illumination load of each illumination device by one control device, as shown in FIG. 17, the control device C and each illumination device L There is a thing that connects to and. However, there is a disadvantage that a wiring work for a control signal line is required and the construction cost is high. Therefore, if a control signal for controlling the illumination load is transmitted as infrared light to each illumination device L from the remote control device R as the control device shown in FIG. For example, see Patent Document 1). However, since a light emitting diode generally used as an infrared light source has infrared light converged by a sealing resin, it is necessary to change the direction of the remote control device R for each lighting device L and transmit the light. In addition, infrared light has a drawback that it is easily blocked by an obstacle. For example, when the illumination devices L1 to L6 are arranged in a room with a partition W as shown in FIG. 19, the illumination device L6 is controlled because infrared light is blocked by the partition W from the position of FIG. I can't.
Japanese Patent No. 3356598

  Therefore, as shown in FIG. 21, there is also provided one that controls each illumination load by a signal transmitted from the control device C as a radio wave. If radio waves are used in this way, signals are not blocked by obstacles such as the partition W, and wiring work for signal lines is not necessary. However, a radio wave having an electric field strength that can be used without a license has a short reach distance, and as shown in FIG. 22, the signal may not reach the illumination loads L5 and L6 away from the control device C. There is a disadvantage that it is not suitable for use in. In addition, the illumination load L7 in an unexpected position such as the adjacent room may be carelessly controlled.

  The present invention has been made in view of the above reasons, and an object of the present invention is to provide an illumination control system that does not require wiring work for control and is suitable for use in a wide place.

  The first aspect of the present invention provides a remote control device having an operation unit that is manually operated, and an infrared transmission unit that transmits a control signal for controlling the illumination load as infrared light in accordance with an operation applied to the operation unit.

It is characterized by that.

  According to this invention, since each illuminating device is controlled using radio waves, the wiring work of the control signal line becomes unnecessary, and the construction cost is reduced. In addition, since the lighting device performs a relay operation, it is possible to control a lighting device to which the control signal of the interface device does not reach directly, which is suitable for use in a wide place.

  The invention of claim 2 is the invention of claim 1, wherein the transmission control unit waits for a different waiting time for each lighting device after the relay request signal transmitted from another lighting device is received by the receiving unit, When the standby time elapses, the response signal is transmitted to the transmission unit, and thereafter, when the control signal is received by the reception unit, the relay operation is performed, and the relay request signal is transmitted to the transmission unit and then transmitted from another lighting device. When the response signal is received by the reception unit, the reception confirmation signal is transmitted to the transmission unit, and when the reception confirmation signal transmitted from another lighting device is received by the reception unit before the end of the standby time, the response signal is transmitted. In addition, the waiting time is ended without performing the relay operation.

  According to the present invention, it is possible to prevent the control signal from being repeatedly relayed by the plurality of lighting devices.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, is the lighting device configured to react to the lighting control unit and the transmission control unit when a control signal transmitted from the interface device is received by the receiving unit? It has an operation setting unit for setting whether to ignore.

  According to the present invention, for example, a lighting device that does not need to respond to a control signal in a different room or the like can be set to ignore the control signal.

  According to a fourth aspect of the present invention, in the first or second aspect of the present invention, the control signal transmitted by the interface device includes identification information indicating the target lighting device, and each lighting device is received by the receiving unit. It has an operation setting means for setting whether the illumination control unit and the transmission control unit react or ignore in accordance with the identification information included in the control signal.

  According to the present invention, for example, a lighting device that does not need to respond to a control signal in a different room or the like can be set to ignore the control signal according to the interface device.

  According to a fifth aspect of the present invention, in the third aspect of the invention, the transmission control unit and the illumination control unit are also in a state where the relay operation is performed and the control signal transmitted from the interface device is received by the reception unit. When the operation setting unit is set to be ignored, the transmission control unit causes the transmission unit to transmit a predetermined reset request signal, and the lighting device receives the reset request signal transmitted from the other lighting device to the reception unit. A reset request notifying unit for notifying a user when received is provided.

  According to the present invention, when a lighting device that has received a relay request signal and is in a state of performing a relay operation is a lighting device that does not need to react to a control signal, the relay route is urged to be reset. it can.

  According to the present invention, since a control signal is transmitted as a radio wave to each lighting device, wiring work for the control signal is not necessary. In addition, since the lighting device performs a relay operation, it is possible to control a lighting device to which the control signal of the interface device does not reach directly, which is suitable for use in a wide place.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
In the present embodiment, as shown in FIG. 1, a remote control device 1 that transmits a control signal for controlling a lamp 31 (see FIG. 4) as an illumination load as infrared light, and a remote control device disposed on a wall surface, for example, 1 comprises an interface device 2 that converts a control signal received from 1 into a radio wave and transmits it, and a plurality of (three in the figure) lighting devices 3a to 3c each having a lamp 31 disposed on the ceiling, for example. 3a to 3c have a function of relaying the control signal A1. By transmitting and receiving the control signal A1 using radio signals such as infrared light and radio waves, wiring work for the signal line for the control signal A1 becomes unnecessary. Further, since the lighting devices 3a to 3c have a function of relaying the control signal A1, the lighting device 3a to 3c can be used even when all the lighting devices 3a to 3c cannot receive the control signal A1 transmitted by the interface device 2 directly. It is also suitable for use in a wide area.

  Here, in order to be able to use it without a license, the interface device 2 and the lighting devices 3a to 3c have a weak radio device or a frequency whose electric field intensity of a transmitted radio wave is equal to or less than an allowable value defined in the Radio Law. It is necessary to be a specific low-power radio device whose band and electric field strength are within the ranges specified by the Radio Law. When the interface device 2 and the lighting devices 3a to 3c are weak radio devices, there is an advantage that the manufacturing cost can be reduced compared to the case of using a specific low power radio device. In addition, when the interface device 2 and the lighting devices 3a to 3c are specified low-power wireless devices, there is an advantage that the distance over which radio waves reach is longer than that when a weak wireless device is used, which is suitable for use in a wider place.

  Hereinafter, each component of this embodiment will be described in detail.

  As shown in FIG. 2, the remote control device 1 includes, for example, an operation unit 11 configured by a push button switch to which a control instruction is input by a manual operation, and a control unit that generates a control signal according to an operation applied to the operation unit. 12 and an infrared transmission unit 13 that is controlled by the control unit 12 and transmits a control signal generated by the control unit 12 as infrared light.

  As shown in FIG. 3, the interface device 2 includes an infrared receiving unit 21 that receives a control signal transmitted from the remote control device 1, a control unit 22, and a radio wave transmission unit 23 that is controlled by the control unit 22 and transmits radio waves. The control unit 22 causes the radio wave control unit 23 to transmit the same control signal A1 as the control signal received by the infrared receiving unit 21 as a radio wave. In addition, the control unit 22 includes a setting switch 24 that is manually operated and serves as a trigger for causing the radio wave transmission unit 23 to transmit a setting signal A2 described later.

  As illustrated in FIG. 4, the lighting devices 3 a to 3 c each include a lamp 31 as a lighting load, a receiving unit 32 that receives the control signal A <b> 1 transmitted by the interface device 2, and a control signal received by the receiving unit 32. And a control unit 33 as an illumination control unit for controlling the lamp 31 based on the control unit 33. The control unit 33 also includes a transmission unit 34 that transmits radio waves under the control of the control unit 33, and the relay request switch 35. The control unit 33 causes the transmission unit 34 to transmit the relay request signal A3 when the relay request switch 35 is operated. . That is, the control unit 33 is also a transmission control unit. In addition, when the relay request signal A3 transmitted from another lighting device is received by the reception unit 32, the control unit 33 turns on the internal transmission flag and causes the transmission unit 34 to transmit the answer signal A4. When the transmission flag is turned on, a relay operation is performed to cause the transmission unit 34 to transmit the same control signal A1 when the control signal A1 is received by the reception unit 32. Furthermore, the illuminating devices 3a to 3c have an LED 36 and an LED extinguishing switch 37, and the control unit 33 receives the setting signal A2 or the answer signal A4 transmitted from the other illuminating devices 3a to 3c. The LED 36 is turned on, and the LED 36 is turned off when the LED turn-off switch 37 is operated. That is, the LED 36 is a reception notification unit. Further, the control unit 33 turns off the transmission flag when the setting signal A2 is received by the receiving unit 32. 4 shows only one lighting device 3a, the other lighting devices 3b and 3c also have a common configuration.

  Next, as shown in FIG. 5, even if the control signal A1 of the interface device 2 reaches the first lighting device 3a in the upper part of the drawing and the second lighting device 3b in the middle of the drawing, the third lighting device 3c in the lower part of the drawing. 6A and 6B, the procedure for setting the relay path so as to relay the control signal A1 to the second lighting device 3b that can communicate with the third lighting device 3c as shown in FIG. This will be described with reference to the time chart of FIG. In addition, the lower left mark of the illuminating devices 3a to 3c in FIG. 6 indicates that the LED 36 is lit.

  First, as shown in FIG. 6A, the user M operates the setting switch 24 of the interface device 2 (S1 in FIG. 7). Then, the control part 22 of the interface apparatus 2 transmits the setting signal A2 to the radio wave transmission part 23 (S2). The first lighting device 3a and the second lighting device 3b each receive the setting signal A2 and turn on the LED 36 (S3). At this time, in the control unit 33 of the first lighting device 3a and the second lighting device 3b, the transmission flag is turned off if the transmission flag is turned on.

  Next, the user M sees that the LED 36 of the third lighting device 3c is not lit, and operates the relay request switch 35 of the third lighting device 3c as shown in FIG. 6B (S4). ). Then, the control unit 33 of the third lighting device 3c causes the transmission unit 34 to transmit the relay request signal A3 (S5). The relay request signal A3 is received by the receiving unit 32 of the second lighting device 3b close to the third lighting device 3c, and the control unit 33 of the second lighting device 3b turns on the internal transmission flag and also performs the processing shown in FIG. ), The response signal A4 is transmitted to the transmission unit 34 (S6). In the third lighting device 3c, the answer signal A4 is received by the receiving unit 32, so that the LED 36 is turned on (S3). In the first lighting device 3a that has not transmitted the relay request signal A3, the control unit 33 ignores the answer signal A4 even if the answer signal A4 is received by the receiving unit 32.

  Finally, the user M confirms that the LEDs 36 of all the lighting devices 3a to 3c are turned on, and operates the LED turn-off switch 37 of each of the lighting devices 3a to 3c as shown in FIG. The LED 36 is turned off. This completes the setting of the relay route.

  Thereafter, when the operation unit 11 of the remote control device 1 is operated as shown in the time chart of FIG. 8 (S9), a control signal is transmitted as infrared light by the remote control device 1 (S10), and the interface device 2 is connected to the remote control device. The control signal A1 received as infrared light from 1 is transmitted as a radio wave (S11), and the first lighting device 3a and the second lighting device 3b control the lamp 31 based on the received control signal A1 (S12). Further, since the transmission flag is on, the control unit 33 of the second lighting device 3b causes the transmission unit 34 to transmit the same control signal A1 as the received control signal A1 (S13), and the third lighting device. In 3c, the control signal A1 transmitted from the second lighting device 3b is received, and the lamp 31 is controlled based on the control signal A1 (S12). Note that, in the first lighting device 3a that has received the control signal A1 directly from the interface device 2, the control unit 33 does not succeed even when the same control signal A1 is received continuously from the second lighting device 3b. The control signal A1 is ignored.

  According to the above configuration, the wiring work of the signal line for the control signal becomes unnecessary, so that the construction cost is reduced. Further, since the lighting devices 3a to 3c have a function of relaying the control signal, even when the control signal A1 transmitted by the interface device 2 does not reach the lighting device 3c directly, the control signal A1 is relayed to the other lighting device 3b. Since the control signal A1 can be delivered to the lighting device 3c, the interface device 2 and the lighting devices 3a to 3c can be used in a wide area even if both the interface devices 2 and the lighting devices 3a to 3c are weak radios with relatively short signal reach. Suitable for use.

  Note that a signal serving as a trigger for causing the interface device 2 to transmit the setting signal A2 may be transmitted from the remote control device 1. According to this configuration, the relay route setting operation becomes easier.

(Embodiment 2)
Since the basic configuration of the present embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals, description thereof is omitted, and only different portions are described.

  In the present embodiment, as shown in FIG. 9A, even when the relay request signal A3 from the third lighting device 3c is received by the plurality of lighting devices 3a and 3b, the plurality of lighting devices 3a and 3b. Prevents the control signal A1 from being repeatedly relayed.

  More specifically, the control unit 33 according to the present embodiment does not cause the reply signal to be transmitted immediately when the relay request signal is received by the reception unit 32, but waits for a standby time determined by a random number. It becomes. That is, the lighting apparatuses 3a and 3b that have received the relay request signal stand by for different times. If the reply signal A4 is received after the relay request signal A3 is transmitted, the reception confirmation signal A5 is transmitted and the LED 36 is turned on. When the reception confirmation signal A5 is received by the reception unit 32 during standby after the reception of the relay request signal A3 by the reception unit 32, the response signal A4 is transmitted to the transmission unit 34 or the transmission flag is turned on. The standby state is terminated without doing so.

  For example, as shown in FIG. 9A, the relay request signal A3 from the third lighting device 3c is received by both the first lighting device 3a and the second lighting device 3b. Will be described with reference to FIGS. 9 and 10. First, the control units 33 of the first lighting device 3a and the second lighting device 3b that have received the relay request signal A3 are both in a standby state (S13).

  Then, when the standby time at the second lighting device 3b ends before the standby time at the first lighting device 3a, the control unit 33 of the second lighting device 3b at FIG. As shown in (b), the response signal A4 is transmitted to the transmitter 34 and the transmission flag is turned on (S6).

  The answer signal A4 transmitted from the second lighting device 3b is received by the receiving unit 32 of the third lighting device 3c, and in response to this, the control unit 33 of the third lighting device 3c is shown in FIG. 9C. Thus, the reception confirmation signal A5 is transmitted to the transmission unit 34 (S14) and the LED 36 is turned on (S3).

  When the reception confirmation signal A5 transmitted from the third illumination device 3c is received by the reception unit 32, the control unit 33 of the first illumination device 3a in the standby state causes the transmission unit 34 to transmit the response signal A4. The standby state is terminated without turning on the transmission flag (S15). That is, the first lighting device 3a does not relay the control signal A1. In the second lighting device 3b that is not in the standby state, the control unit 33 ignores the reception confirmation signal A5 even if the reception confirmation signal A5 is received.

  According to the above configuration, since the control signal A1 is not relayed except for the lighting device 3b that has finished the standby state first, the plurality of lighting devices 3b and 3c are prevented from repeating the control signal. .

(Embodiment 3)
Since the basic configuration of the present embodiment is the same as that of the second embodiment, common portions are denoted by the same reference numerals, description thereof is omitted, and only different portions are described.

  Here, as shown in FIG. 11, not only the third lighting device 3c but also the second lighting device 3b that can communicate with the third lighting device 3c is the control signal A1 and the setting signal of the interface device 2. Consider a state where A2 cannot be received. In such a case, in the first and second embodiments, in order to make the control signal A1 reach the third lighting device 3c, the relay request switch 35 of the second lighting device 3b is operated first. Therefore, it is necessary to operate the relay request switch 35 of the third lighting device 3c. In the present embodiment, even in the state as shown in FIG. 11, the relay route is set so that the control signal A1 reaches the third lighting device 3c only by operating the relay request switch 35 of the third lighting device 3c. It can be set.

  Specifically, in the lighting devices 3a to 3c, when neither the setting signal A2 nor the answer signal A4 is received and the LED 36 is not lit and the relay request signal A3 is received by the receiving unit 32. The control unit 33 transmits the relay request signal A3 to the transmission unit 34. When the response signal A4 is subsequently received by the reception unit 32, the control unit 33 transmits the response signal A4 to the transmission unit 34 and turns on the transmission flag. did. In addition, when the standby time ends after the relay request signal A3 is transmitted to the transmission unit 34 until the answer signal A4 is received by the reception unit 32, the control unit 33 determines the standby time again. Enter standby again.

  The operation of this embodiment will be described in detail. As shown in FIG. 12A, when the user M operates the relay request switch 35 of the third lighting device 3c, the control unit 33 of the third lighting device 3c causes the transmission unit 34 to transmit the relay request signal A3. The relay request signal A3 is received by the second lighting device 3b. At this time, since neither the setting signal A2 nor the answer signal A4 is received in the second lighting device 3b and the LED 36 is not lit, the control unit 33 of the second lighting device 3b is shown in FIG. As shown, the relay request signal is transmitted to the transmitter 32.

  The relay request signal transmitted from the second lighting device 3b is received by the receiving unit 32 of the first lighting device 3a, and the control unit 33 of the first lighting device 3a is shown in FIG. In this way, the response signal is transmitted to the transmission unit 34 and the transmission flag is turned on. This answer signal is received by the receiving unit 32 of the second lighting device 3b, and in response to this, the control unit 33 of the second lighting device 3b transmits a reception confirmation signal A5 as shown in FIG. 12 (d). Further, when the standby time is over, the reply signal A4 is transmitted to the transmitter 34 and the transmission flag is turned on. In the third lighting device 3c, when the answer signal A4 transmitted from the second lighting device 3b is received by the receiving unit 32, the control unit 33 generates the reception confirmation signal A5 as shown in FIG. The transmission unit 33 transmits the light and the LED 36 is turned on.

  Thereafter, the first lighting device 3a relays the control signal A1, so that the second lighting device 3b also receives the control signal A1, and the second lighting device 3b relays the control signal A1 and the third lighting device 3b relays the control signal A1. The control signal A1 also reaches the lighting device 3c.

  If the said structure is employ | adopted, in the case like FIG. 11, the control signal A1 can be sent to the 3rd lighting apparatus 3c only by operating the relay request switch 35 of the 3rd lighting apparatus 3c, and 2nd Since it is not necessary to operate the relay request switch 35 of the lighting device 3b, the operation is simplified as compared with the first and second embodiments.

(Embodiment 4)
Since the basic configuration of the present embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals, description thereof is omitted, and only different portions are described.

  In the present embodiment, the configuration is simplified by using the control signal A1 instead of the setting signal A2 and the answer signal A4 and using the lamp 31 instead of the LED 36.

  That is, the interface device 2 of this embodiment does not have the setting switch 24 as shown in FIG. Further, as illustrated in FIG. 14, the lighting devices 3 a to 3 c do not have the LED 36 and the LED extinguishing switch 37, and the initialization switch 38 that triggers the control unit 33 to turn off the transmission flag is received last. And a control signal storage unit 39 in which the control signal A1 is stored.

  The control unit 33 updates the control signal A1 stored in the control signal storage unit 39 every time the reception unit 32 receives the control signal A1, and when the relay request signal A3 is received by the reception unit 32. The transmission flag is turned on, and the control signal A1 stored in the control signal storage unit 39 is transmitted to the transmission unit 34.

  As shown in FIG. 15A, when the remote control device 1 tries to turn on the lamps 31 of all the lighting devices 3a to 3c, the case where the lamps 31 of the third lighting device 3c are not turned on will be considered. Here, in FIGS. 15A to 15C, the radial marks below the illumination devices 3a to 3c indicate that the lamps 31 of the illumination devices 3a to 3c are lit. In this case, the user M may operate the relay request switch 35 of the third lighting device 3c where the lamp 31 is not lit. Then, as shown in FIG. 15B, the relay request signal A3 is transmitted from the third lighting device 3c, and in the second lighting device 3b that has received this relay request signal A3, the control unit 33 turns on the transmission flag. At the same time, the control signal A1 stored in the control signal storage unit 39, that is, the control signal A1 for lighting the lamp 31, is transmitted to the transmission unit. The control signal A1 is received by the receiving unit 32 of the third lighting device 3c, whereby the lamp 31 of the third lighting device 3c is turned on as shown in FIG. 15 (c). Further, since the transmission flag of the control unit 33 of the second lighting device 3b is turned on, the control signal A1 can be relayed to the second lighting device 3b thereafter.

  According to the above configuration, since it is not necessary to operate the setting switch 24 of the interface device 2 and the LED turn-off switch 37 of the lighting devices 3a to 3c as compared with the first embodiment, the lighting device 3b starts relaying the control signal. The operation becomes easier.

(Embodiment 5)
Since the basic configuration of the present embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals, description thereof is omitted, and only different portions are described.

  In the present embodiment, as shown in FIG. 16, for example, it is assumed that the same type of lighting control system is used in rooms adjacent to each other, and depending on the control signal of the interface device 2 to belong to another lighting control system. This prevents the lamp 31 of the lighting device 3d that does not need to be controlled from being controlled.

  That is, the setting signal A2 and the control signal A1 transmitted by the interface device 2 include identification information indicating the source interface device 2, and the control unit 33 receives the setting signal A2 transmitted from a certain interface device 2 as a receiving unit. When the LED turn-off switch 37 is not operated within a predetermined time after the LED 36 is turned on and received, the LED 36 is automatically turned off. Further, thereafter, the setting signal A2 and the control signal A1 transmitted from the interface device 2 are ignored. That is, the control unit 33 serves as an operation setting unit and an operation setting unit. Here, the identification information may be a unique number for each interface device 2 or a channel that can be freely set in the interface device 2.

  As the operation setting unit and the operation setting means, the lighting devices 33a to 33d are provided with switches serving as triggers that cause the control unit 33 to turn off the LED 36 and ignore the setting signal A2 and the control signal A1 transmitted from the interface device 2. May be.

  According to the said structure, it can prevent that the lamp | ramp 31 of the illuminating device 3d which does not need to be controlled by the control signal A1 of the interface apparatus 2 will be carelessly controlled.

  Further, when the control unit 33 switches to a state in which the setting signal A2 and the control signal A1 transmitted from the interface device 2 are ignored, if the transmission flag is turned on, the control unit 33 causes the transmission unit 34 to transmit a reset request signal. When the reset request signal transmitted from the other lighting device 3d is received by the receiving unit 32, the lamp 31 may blink. In this case, the lamp 31 serves as a reset request notification unit. Here, instead of using the illuminating device 31, for example, a buzzer may be provided in the illuminating devices 3 a to 3 d as the reset request notifying unit and driven.

  If this configuration is adopted, when the lighting device 3d that switches to a state in which the setting signal A2 and the control signal A1 transmitted from the interface device 2 are ignored is in a state in which the control signal A1 is to be relayed, It is possible to prompt the user to reset the relay route by blinking or sounding a buzzer.
