  The present invention has been invented in view of the above-described background art, and an object thereof is to provide a wireless remote control system capable of controlling a controlled device with a simple operation without directly operating a remote control.

  In order to solve the above-described problems, the present invention provides a transmitter that continuously transmits a wireless remote control signal of an optical medium without a manipulation from the outside when the power is turned on, a receiver that receives the wireless remote control signal, And a controlled device that operates according to a reception result of the wireless remote control signal at the receiver, and the receiver is controlled with a predetermined criterion when the receiver does not receive the wireless remote control signal from the transmitter. In a wireless remote control system configured to cause a device to operate, the transmitter transmits the wireless remote control signal through a plurality of optical paths, and the receiver receives a plurality of the wireless remote control signals through a plurality of optical paths. The receiving device is provided, and the controlled device can switch its operation in accordance with the receiving unit in which reception of the wireless remote control signal is interrupted. Here, if the wireless remote control signal is visible light, it goes without saying that it is easy to distinguish the wireless remote control signal to be selected, but conversely, if the wireless remote control signal travels multiple paths, The wireless remote control signal may be invisible light with an infrared band wavelength instead of visible light.

  Moreover, it is preferable that the controlled device is controlled and operated based on the number of times the wireless remote controller signal is cut off within a predetermined time of the receiver.

  Moreover, it is preferable that the controlled device is controlled and operated on the basis of the duration of the wireless remote control signal cutoff of the receiver.

  In addition, a human body detection device for detecting a human body is provided, and when the human body detection device does not detect a human body, the transmitter stops sending the wireless remote control signal, and the human body detection device does not detect a human body. During the period when the receiver does not receive the wireless remote control signal, the controlled device is stopped, and when the human body detecting device detects the human body, the transmitter resumes transmitting the wireless remote control signal, and the reception The device that resumes the operation of the controlled device when receiving the same wireless remote control signal is generally low in power consumption of the human body detection device, from the viewpoint of reducing the power required for the system of the present invention, Particularly preferred.

  Furthermore, when a security application device that is one type of the controlled device is attached, and the human body detection device does not detect a human body, the transmitter stops sending the wireless remote control signal, and the human body detection device When the receiver does not receive a wireless remote control signal, the operation of the controlled device is stopped, the security application device is operated, and the human body detection device detects a human body. The transmitter resumes sending the wireless remote control signal, and the receiver restarts the operation of the controlled device when the receiver receives the wireless remote control signal and stops the operation of the security application device.

When it is received, the operation of the controlled device is resumed. Therefore, when there is no person, the controlled device does not operate, thus saving energy. Furthermore, since no wireless remote control signal is transmitted, energy is saved. Since the power consumption of the human body detection device is generally low, it is particularly preferable from the viewpoint of reducing the power required for the system of the present invention.

  Furthermore, when a security application device, which is one type of controlled device, is attached and the human body detection device does not detect a human body, the transmitter stops sending the wireless remote control signal, and the human body detection device does not detect the human body. During the period when the receiver does not receive the wireless remote control signal, the controlled device is stopped and the security application device is operated. When the human body detection device detects the human body, the transmitter sends the wireless remote control signal. If the receiver receives the wireless remote control signal, the receiver restarts the controlled device and stops the security device. This is an effective form that satisfies both the desire to reduce the power required for the system of the present invention and the crime prevention. From the viewpoint of the visual aspect and energy saving, particularly preferred.

[First Reference Example ]
A wireless remote control system 1 of a first reference example will be described with reference to FIGS. FIG. 1 is a system configuration diagram of a wireless remote control system 1 according to a first reference example , and FIG. 2 is a flowchart of the above. The wireless remote control system 1 of this reference example includes a transmitter 2 that wirelessly transmits a wireless remote control signal 5 and a receiver 3 that receives the wireless remote control signal 5 (incorporated integrally or wired together). a control device 4 comprises, as a large feature, are widely used in conventional streets, unlike the type of remote control that emits radio signals in response to the operation button, the transmitter 2 if put power of the transmitter 2 Even if there is no operation from the outside, the wireless remote control signal 5 is continuously transmitted, and the receiver 3 controls the controlled device 4 according to a predetermined criterion when the wireless remote control signal 5 from the transmitter 2 is not received. This is a wireless remote control system that sends a signal 34 so that the controlled device 4 is controlled based on the control signal 34 from the receiver 3. In addition, the transmitter 2 sends out the wireless remote control signal 5 as an optical signal using a plurality of linear optical paths, and the controlled device 4 determines whether one of the plurality of receivers 3 is interrupted to receive the wireless remote control signal 5. The operation mode (power on / off, high / low operation speed, etc.) can be switched. In other words, the controlled device 4 operates in accordance with a straight optical path blocked from the plurality of optical signals via the control signal 34 from the receiver 3.

  The transmitter 2 transmits the wireless remote control signal 5 as an optical signal using a plurality of linear optical paths, and generates a signal generator 21 that generates a signal and a signal amplifier 22 that amplifies the signal generated by the signal generator 21. A first wireless remote control signal sending unit 23a that sends the signal amplified by the signal amplification unit 22 as a first wireless remote control signal 5a, and a signal amplified by the signal amplification unit 22 as a second wireless remote control signal 5b And a second wireless remote control signal transmitter 23b for transmitting as The first wireless remote control signal 5a and the second wireless remote control signal 5b are not limited to different signals, and may be operated as the same signal format and the same signal code. Which one to adopt depends largely on whether the system design is accepted or not, and should be determined based on the convenience of the structural arrangement of the place where the system is actually installed and the influence of disturbance light. .

  The receiver 3 has a timer function capable of measuring time, receives the wireless remote control signal 5 sent from the transmitter 2, and senses the blocked wireless remote control signal 5 (straight light path). When the wireless remote control signal 5 is interrupted, the control signal 34 is transmitted according to a predetermined criterion for controlling the controlled device 4. This includes a first wireless remote control signal receiving unit 31a that receives the wireless remote control signal 5a, a second wireless remote control signal receiving unit 31b that receives the wireless remote control signal 5b, and a first wireless remote control signal receiving unit 31a. The first radio amplifier signal 32a that amplifies the received radio remote control signal 5a to a size that can be processed in the next process, and the radio remote control signal 5b received by the second radio remote control signal receiver 31b is amplified to a magnitude that can be processed in the next process. The second signal amplifying unit 32b, and the wireless remote control signal 5 amplified by the signal amplifying units 32a and 32b, and the control signal 34 according to a predetermined criterion for controlling the controlled device 4 And a signal processing unit 33 for transmitting the signal. The controlled device 4 includes the receiver 3 described above (in FIG. 1, it is illustrated as being integrated, but is not limited thereto, and is configured separately from each other and connected by wire. However, the operation is based on the control signal 34 from the receiver 3.

  Here, the predetermined determination criterion provided in the signal processing unit 33 is, for example, a lighting fixture of a type that can be controlled from the outside as the controlled device 4. In response to the fact that the wireless remote control signal 5 (one of the wireless remote control signal 5a and the wireless remote control signal 5b may be received) cannot be received for more than one second, the control signal 34 for turning on or off the power of the lighting fixture is supplied to the lighting fixture. The luminaire that has received the control signal 34 performs an operation of turning on the power of the luminaire if it is not ON, or turning it OFF if it is not OFF.

  The operation of the wireless remote control system 1 will be described with reference to the flowchart of FIG. First, when the power source (not shown) of the transmitter 2 is turned on (step S1), a signal is generated from the signal generator 21, and the first radio is generated based on the signal amplified by the signal amplifier 22. Radio remote control signals 5a and 5b are sent out by the remote control signal sending unit 23a and the second radio remote control signal sending unit 23b. The wireless remote control signals 5a and 5b from the wireless remote control signal transmission units 23a and 23b are continuously transmitted. The wireless remote control signals 5a and 5b are directional light such as infrared rays (step S2).

  In step S1, when the controlled device 4 including the receiver 3 is turned on (not shown), the controlled device 4 is turned on, and at the same time, the receiver 3 is turned on (not shown). In step S2, the wireless remote control signal receiving unit 31 is ready to receive the wireless remote control signal 5.

  Then, the receiver 2 and the receiver 3 (the controlled device 4) are placed next to the installer or the residence so that the receiver 3 can stably receive the wireless remote control signals 5a and 5b from the transmitter 2 (step S3). (Step S4). Here, the state in which the wireless remote control signal 5 can be stably received means that the receiver 3 can continuously receive the wireless remote control signal 5 without interruption, without a sudden phase change, and without a sudden power change. Say that you are. Hereinafter, this state is referred to as a standby state (step S5). In step S3, if the receiver 3 is in a non-reception state or is in an unstable reception state even if it is received, the signal processing unit 33 notifies the receiver 3 by a reception state display LED or a buzzer sound. By controlling the means (not shown), the fact that the first wireless remote control signal receiver 31 (31a, 31b) has not captured the wireless remote control signal 5 (5a, 5b) is notified to the surroundings.

In this standby state, when the receiver 3 cannot receive any one of the wireless remote control signals 5a and 5b among the wireless remote control signals 5, that is, when it is detected that the wireless remote control signal 5 is blocked (step S6). The signal processing unit 33 sends a control signal 34 to the controlled device 4 according to a predetermined criterion. As the control signal 34 for performing a plurality of controls, here, four types of symbols 34a, 34b, 34c, and 34d representing four types of individual commands are exemplified. The controlled device 4 that has received any one of the control signals 34 a, 34 b, 34 c, 34 d performs a predetermined operation according to the control signal 34. In order to determine which of the control signals 34a, 34b, 34c, and 34d is to be transmitted, the signal processing unit 33 is provided in advance with mutually independent determination criteria shown in the following (1) to (4).
(1) When only the wireless remote control signal 5 a is interrupted, the receiver 3 sends a control signal 34 a to the controlled device 4. When the controlled device 4 receives the control signal 34a, the controlled device 4 performs, for example, an alternate operation to turn on or off the power (step S7, step S8, step S9).
(2) When only the wireless remote control signal 5 b is interrupted, the receiver 3 sends a control signal 34 b to the controlled device 4. When the controlled device 4 receives the control signal 34b, for example, the controlled device 4 performs an operation of increasing the brightness (step S10, step S11, step S12).
(3) When the wireless remote control signals 5 a and 5 b are blocked in this order, the receiver 3 sends a control signal 34 c to the controlled device 4. When the controlled device 4 receives the control signal 34c, the controlled device 4 performs, for example, an operation of reducing the brightness (step S13, step S14, step S15).
(4) When blocking in the order of the wireless remote control signals 5b and 5a, the receiver 3 sends a control signal 34d to the controlled device 4. When receiving the control signal 34d, the controlled device 4 performs, for example, a blinking operation (Step S16, Step S17, Step S18).

  After any of step S9, step S12, step S15, or step S18, the receiver 3 and the controlled device 4 return the operation to immediately before step S3.

  The wireless remote control system 1 configured as described above is a receiver that sets and operates a plurality of optical paths so as to transmit and receive the wireless remote control signal 5 through a plurality of linear optical paths, and senses and operates the linear optical path of the blocked wireless remote control signal 5. 3, the controlled device 4 is controlled via the wireless remote control system 3, so that the wireless remote control can be operated by waving a hand between the transmitter 2 and the receiver 3 of the wireless remote control system 1 or putting an obstacle or the like. When the signal 5 is blocked and the receiver 3 cannot sense the wireless remote control signal 5, the receiver 3 sends a control signal 34 to the controlled device 4 with a predetermined criterion.

Therefore, the controlled device 4 can operate the controlled device 4 without operating the transmitter 2 by performing an operation based on the control signal 34. In FIG. 1 and FIG. 2, there are two wireless remote control signals 5a and 5b. However, by further increasing the number of wireless remote control signals, the controlled device 4 can be controlled in various ways.
[Second Reference Form]
The wireless remote control system 1 of the second reference embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is an explanatory diagram of the wireless remote control system 1 of the second reference embodiment, and FIG. 4 is a flowchart for explaining the operation of the wireless remote control system 1 of FIG.

The feature of the wireless remote control system 1 of this reference embodiment, which is different from the first reference embodiment described above, is that the controlled device 4 is based on the number of times the wireless remote control signal 5 of the receiver 3 is detected within a predetermined time. is the point of controlling the, others are the same as in the first referential embodiment, a detailed description thereof will be omitted. Here, only the first wireless remote control signal receiving unit 31a in the wireless remote control signal receiving unit 31 will be described as an example. Therefore, only the first wireless remote control signal sending unit 23a corresponding to the first wireless remote control signal receiving unit 31a will be described as an example on the transmission side. The transmission / reception pair of the first wireless remote control signal receiver 31b and the first wireless remote control signal transmitter 23b is the same as the transmission / reception pair of the first wireless remote controller signal receiver 31a and the first wireless remote controller signal transmitter 23a. The above-described first reference form may be used.

  The signal processing unit 33 can count the number of times that the wireless remote control signal 5a is interrupted, that is, how many times the wireless remote control signal 5 is detected within a predetermined time set within, for example, one second. In accordance with the count number, a control signal 34 of a predetermined criterion is sent to the controlled device 4.

As a predetermined determination criterion of the signal processing unit 33 of this reference form, for example, when the wireless remote control signal 5a cannot be received for 0.1 second or longer, the signal processing unit 33 determines that “the hand has been blocked”. Further, when the wireless remote control signal 5a can be received for 0.1 second or longer, the signal processing unit 33 determines that it is “not blocked by hand”. Further, when the wireless remote control signal 5a satisfies the following conditions (1) to (3), the control signal 34 is transmitted.
(1) When the wireless remote control signal 5a is interrupted once within 1 second, a control signal 34a is transmitted.
(2) When the wireless remote control signal 5a is interrupted twice within 1 second, a control signal 34b is transmitted.
(3) If the wireless remote control signal 5a is interrupted three times or more within 1 second, a control signal 34c is transmitted.

  Next, the operation of the wireless remote control system 1 will be described.

  First, as shown in FIG. 3, the wireless remote control signal 5a that is in a standby state (A) because reception is continued is blocked for 0.3 seconds (B). Thereafter, the wireless remote control signal 5a is set in a state where it can be received without being interrupted for 0.3 seconds (c), and then the wireless remote control signal 5 is blocked for 0.2 seconds (d). Thereafter, the wireless remote control signal 5a is made receivable until a predetermined time of 1 second elapses (e). When one second has elapsed since the wireless remote control signal 5a was first interrupted, the signal processing unit 33 counts how many times the wireless remote control signal 5a is interrupted within a predetermined time, and a control signal corresponding to the number of times the wireless remote controller signal 5a is interrupted 34 is sent to the controlled device 4. In this case, since the wireless remote control signal 5 a is interrupted twice per second, the signal processing unit 33 outputs a control signal 34 b to the controlled device 4. The controlled device 4 that has received the control signal 34b performs a predetermined operation according to the content of the received control signal 34b.

The operation of the wireless remote control system 1 will be described with reference to the flowchart of FIG. Through step S5 described in the first reference embodiment, the sensing in the standby state, the wireless remote control signal 5a of the receiver 3 wireless remote control signal 5 can not be received, i.e., that the wireless remote control signal 5 is blocked Then (step S6-1), the signal processing unit 33 sends a control signal 34 to the controlled device 4 according to a predetermined criterion. As the control signal 34 for performing a plurality of controls, three types of symbols 34a, 34b, and 34c representing three types of individual commands are illustrated here. The controlled device 4 that has received any of the control signals 34 a, 34 b, 34 c performs a predetermined operation according to the control signal 34. In order to determine which of the control signals 34a, 34b, and 34c is to be transmitted, the signal processing unit 33 is provided in advance with the following independent criteria shown in (1) to (3) below.
(1) When the wireless remote control signal 5a is interrupted only once within one second (that is, only once for 0.1 second or longer), the receiver 3 sends a control signal 34a to the controlled device 4. . When the controlled device 4 receives the control signal 34a, the controlled device 4 performs, for example, an alternate operation to turn on or off the power (step S7-1, step S8-1, step S9-1).
(2) When the wireless remote control signal 5a is interrupted only twice within one second (that is, only two interruptions continued for 0.1 seconds or more), the receiver 3 sends a control signal 34b to the controlled device 4. To do. When the controlled device 4 receives the control signal 34b, for example, the controlled device 4 performs an operation of increasing the brightness (step S10-1, step S11-1, and step S12-1).
(3) When the wireless remote control signal 5a is interrupted three times or more within one second (that is, three or more interruptions continued for 0.1 seconds or more), the receiver 3 sends a control signal 34c to the controlled device 4. To do. When the controlled device 4 receives the control signal 34c, the controlled device 4 performs, for example, an operation of reducing the brightness (Step S13-1, Step S14-1, Step S15-1).

Either after step S9-1 or Step S12-1 or step S15-1, the receiver 3 and the controlled apparatus 4, as in the first reference embodiment of the operation, just prior to the step S3 in FIG. 2 return.

  The wireless remote control system 1 configured as described above controls the controlled device 4 via the receiver 3 based on the number of times the wireless remote control signal 5a is detected within a predetermined time of the receiver 3a. The first remote control signal 5a is blocked by performing an operation such as slightly waving between the one remote control signal sending unit 23a and the first remote control signal receiving unit 31a or an operation of putting an obstacle or the like. When the remote control signal receiver 31a cannot sense the wireless remote control signal 5a, the receiver 3 sends a control signal 34 to the controlled device 4 with a predetermined criterion.

Therefore, the controlled device 4 can operate the controlled device 4 without operating the transmitter 2 by performing an operation based on the control signal 34. 3 and 4, the wireless remote control signal is only 5a, but the controlled device 4 can be controlled more variously by further increasing the number of wireless remote control signals.
[Third Reference Form]
The wireless remote control system 1 of the third reference embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is an explanatory diagram of the wireless remote control system 1 of the second reference embodiment, and FIG. 6 is a flowchart for explaining the operation of the wireless remote control system 1 of FIG.

The feature of the wireless remote control system 1 of this reference embodiment, which is different from the first reference embodiment described above, is that the controlled device 4 is controlled based on the duration of the cutoff time of the wireless remote control signal 5. Since others are the same as those in the first reference embodiment, detailed description thereof is omitted. Here, only the first wireless remote control signal receiving unit 31a in the wireless remote control signal receiving unit 31 will be described as an example. Therefore, only the first wireless remote control signal sending unit 23a corresponding to the first wireless remote control signal receiving unit 31a will be described as an example on the transmission side. The transmission / reception pair of the first wireless remote control signal receiver 31b and the first wireless remote control signal transmitter 23b is the same as the transmission / reception pair of the first wireless remote controller signal receiver 31a and the first wireless remote controller signal transmitter 23a. The above-described first or second reference mode may be used.

  The signal processing unit 33 can count the duration for which the wireless remote control signal 5a is interrupted, and sends a control signal 34 based on a predetermined criterion according to the counted interruption duration for the controlled device 4. To send.

As a predetermined determination criterion of the signal processing unit 33 of this reference form, for example, when the wireless remote control signal 5a cannot be received for 0.1 second or longer, the signal processing unit 33 determines that “the hand has been blocked”. Further, when the wireless remote control signal 5 can be received for 0.1 second or longer, the signal processing unit 33 determines that it is “not blocked by hand”. Further, when the wireless remote control signal 5a satisfies the following conditions (1) to (3), the control signal 34 is transmitted.
(1) If the interruption duration time of the wireless remote control signal 5a is less than 1 second, the control signal 34a is transmitted.
(2) If the cutoff duration of the wireless remote control signal 5a is not less than 1 second and less than 3 seconds, the control signal 34b is transmitted.
(3) If the cutoff duration of the wireless remote control signal 5a is 3 seconds or more, a control signal 34c is sent.

  Next, the operation of the wireless remote control system 1 will be described.

  First, as shown in FIG. 5, the radio remote control signal 5a that is in a standby state (A) because reception is continued is blocked for 2 seconds (B). Thereafter, the wireless remote control signal 5a is set in a state where it can be received without being interrupted for 0.1 second or longer (c). In this case, since the wireless remote control signal 5 a is interrupted for 1 second or more and less than 3 seconds, the signal processing unit 33 outputs a control signal 34 b to the controlled device 4. The controlled device 4 that has received the control signal 34b performs a predetermined operation according to the content of the received control signal 34b.

The operation of such a wireless remote control system 1 will be described using the flowchart of FIG. Through step S5 described in the first reference embodiment, the sensing in the standby state, the wireless remote control signal 5a of the receiver 3 wireless remote control signal 5 can not be received, i.e., that the wireless remote control signal 5 is blocked Then (step S6-2), the signal processing unit 33 sends a control signal 34 to the controlled device 4 according to a predetermined criterion. As the control signal 34 for performing a plurality of controls, three types of symbols 34a, 34b, and 34c representing three types of individual commands are illustrated here. The controlled device 4 that has received any of the control signals 34 a, 34 b, 34 c performs a predetermined operation according to the control signal 34. In order to determine which of the control signals 34a, 34b, and 34c is to be transmitted, the signal processing unit 33 is provided in advance with the following independent determination criteria (1) to (3).
(1) When the wireless remote control signal 5a is interrupted in less than 1 second, the receiver 3 sends a control signal 34a to the controlled device 4. When the controlled device 4 receives the control signal 34a, the controlled device 4 performs, for example, an alternate operation in which the power is turned on or off (step S7-2, step S8-2, step S9-2).
(2) When the wireless remote control signal 5 a is interrupted for 1 second or more and less than 3 seconds, the receiver 3 sends a control signal 34 b to the controlled device 4. When the controlled device 4 receives the control signal 34b, for example, the controlled device 4 performs an operation of increasing the brightness (step S10-2, step S11-2, step S12-2).
(3) When the wireless remote control signal 5 a is continuously interrupted for 3 seconds or more, the receiver 3 sends a control signal 34 c to the controlled device 4. When the controlled device 4 receives the control signal 34c, for example, the controlled device 4 performs an operation of reducing the brightness (step S13-2, step S14-2, step S15-2).

After either step S9-2, step S12-2, or step S15-2, the receiver 3 and the controlled device 4 operate in the same manner as in the first reference embodiment, immediately before step S3 in FIG. return.

  Since the wireless remote control system 1 configured as described above controls the controlled device 4 via the receiver 3 based on the duration of the cutoff time of the wireless remote control signal 5a of the receiver 3a, the first remote control signal The first remote control signal is received by blocking the wireless remote control signal 5a by performing an operation such as slightly waving or sending an obstacle between the sending unit 23a and the first remote control signal receiving unit 31a. When the unit 31a cannot detect the wireless remote control signal 5a, the receiver 3 sends a control signal 34 to the controlled device 4 with a predetermined criterion.

Therefore, the controlled device 4 can operate the controlled device 4 without operating the transmitter 2 by performing an operation based on the control signal 34. 5 and 6, the wireless remote control signal is only 5a. However, the controlled device 4 can be controlled more variously by increasing the number of wireless remote control signals.

Figure 7 is a system configuration diagram of a radio remote control system 1 of the fourth reference embodiment, FIG. 8 is a flow chart of the same. This reference form is provided with a human body detection device 6 as compared with the first reference form described above, and the transmitter 2 is provided with a function corresponding to the human body detection device 6, and the other points are the first.

When the human body detection device 6 detects a human body from a state in which no human body is detected, the human body detection device 6 sends a control signal 61 (61a) to that effect to the transmitter 2. When no human body is detected from the state in which the human body is detected, a control signal 61 (61b) to that effect is sent to the transmitter 2. The control signals 61a and 61b may be the same signal for alternate control or may be different command signals. That is, the human body detection device 6 sends the control signal 61 to the transmitter 2 when the human body detection device 6 detects a human body without detecting the human body or when the human body detection device 6 detects the human body. This is a case where the human body is no longer detected in a state where it is detected.

Here, the operation of the wireless remote control system 1 will be described. Since the state in which the human body detection device 6 is detecting a human body performs the same operation as that of the first reference embodiment described above, description thereof is omitted.

  Next, a case will be described in which the human body detection device 6 is in a state where it no longer detects a human body from a state where it detects the human body. The human body detection device 6 sends a control signal 61b to the transmitter 2 to the effect that “the sending of the wireless remote control signal 5 is stopped”. The transmitter 2 stops sending the wireless remote control signal 5 by this control signal 61b. The receiver 3 senses that the wireless remote control signal 5 is blocked when the wireless remote control signal 5 from the transmitter 2 cannot be continuously received for a very long period of time such as several minutes rather than 0.1 second. Then, a control signal 34 indicating that “the power source of the controlled device 4 is turned off” is sent to the controlled device 4. The controlled device 4 that has received the control signal 34 turns off the power of the controlled device 4.

  For example, when a lighting fixture is used as the controlled device 4, the lighting of the lighting fixture is turned on by blocking the wireless remote control signal 5 sent from the transmitter 2 when the human body detection device 6 is detecting a human body. Although the human body detection device 6 has not switched to the OFF state, that is, when all persons in the room where the lighting apparatus is installed go out, the lighting of the lighting apparatus can be turned off.

  The operation of such a system will be described with reference to FIG. It is determined whether or not the human body detection device 6 detects a human body (step S19). If the determination result indicates that a human body has been detected, the previous detection result is referred to (step S20), and the previous human body is also detected. Then, since there is no change in the presence of the human body, the human body detection device 6 does not send the control signal 61a to the transmitter 2 and returns to step S19 (step S21).

If the human body was not previously detected in step S20, this means that the human body has been detected this time, so that the human body detection device 6 controls the transmitter 2 to “start transmission of the wireless remote control signal 5”. The signal 61a is sent out (step S22). With this control signal 61a, the transmitter 2 starts sending out the wireless remote control signal 5 (step S23). The receiver 3 receives the wireless remote control signal 5 in a state where the wireless remote control signal 5 from the transmitter 2 cannot be received for a predetermined time or more (step S24). A control signal 34 indicating that the power is turned on is sent (step S25). The controlled device 4 that has received the control signal 34 turns on the power of the controlled device 4 (step S26), and although not shown in the flowchart of FIG. When the operation shifts immediately after the standby state (step S5) in the reference mode and the operation returns again immediately before step S5, the transmitter 2 and the human body detection device 6 return the operation immediately before step S19. .

  On the other hand, in step S19, it is determined whether or not the human body detection device 6 has detected a human body. If the determination result indicates that no human body has been detected, the previous detection result is referred to (step S27). If it has not been detected, there is no change in the absence of the human body, so the human body detection device 6 does not send the control signal 61b to the transmitter 2 and returns to step S19 (step S21).

  If the human body was detected at the previous time in step S27, it means that the human body has not been detected at this time. Therefore, the human body detection device 6 controls the transmitter 2 to stop sending the wireless remote control signal 5. The signal 61b is sent out (step S28). With this control signal 61b, the transmitter 2 starts sending the wireless remote control signal 5 (step S29). Then, when the wireless remote control signal 5 from the transmitter 2 has been continuously received until then, the receiver 3 cannot receive the wireless remote control signal 5 for a long time such as several minutes (step S30). A control signal 34 is sent to the device 4 to “turn off the power to the controlled device 4” (step S31). The controlled device 4 that has received the control signal 34 turns off the power of the controlled device 4 (step S32), and the transmitter 2 and the human body detection device 6 return to operation immediately before step S19.

Thus, for example, when using a luminaire as the controlled apparatus 4, in the operation described in the first reference embodiment, the lighting of the luminaire by blocking the wireless remote control signals 5 sent from the transmitter 2 The human body detection device 6 detects the presence of the human body by the person entering the human body detection region of the human body detection device 6 from the state in which the human body detection device 6 has not detected the human body that has been switched ON or OFF, It is also possible to turn on the lighting of the lighting fixture.

  That is, there is a human body detection device 6 for detecting a human body, and when the human body detection device 6 does not detect a human body, the transmitter 2 stops sending the wireless remote control signal, and the human body detection device 6 does not detect a human body. When the receiver 3 does not receive the wireless remote control signal, the controlled device 4 is stopped, and when the human body detection device 6 detects the human body, the transmitter 2 resumes transmitting the wireless remote control signal. 3 resumes the operation of the controlled device 4 when a wireless remote control signal is received. Accordingly, when there is no person, the controlled device 4 does not operate, which can contribute to energy saving. Furthermore, since no wireless remote control signal is transmitted, it can contribute to energy saving. Since the power consumption of the human body detection device is generally low, it is particularly preferable from the viewpoint of reducing the power required for the system of the present invention.

As described above with reference to FIG. 7, the transmitter 2 stops sending the wireless remote control signal 5 when the human body detection device 6 does not detect a human body. From this remote control signal transmission stop state, the human body detection device 6 is stopped. More preferably, when the human body is detected and the transmitter 2 resumes sending the wireless remote control signal 5, the controlled device 4 is controlled in conjunction with the human body detection result of the human body detection device 6. In this way, the combined use with the third reference embodiment described above can be realized with few malfunctions.
Embodiment of the present invention
A wireless remote control system 1 according to an embodiment of the present invention will be described with reference to FIGS. FIG. 9 is a system configuration diagram of the wireless remote control system 1 of the fifth reference embodiment, and FIG. 10 is a flowchart showing the operation of the system of FIG. That the embodiment of the present invention is characterized unlike the fourth reference embodiment includes a security application device 4a, which is one type of the controlled apparatus 4, the period in which the human body is detected fourth reference described above operates as a wireless remote control system 1, the period in which the human body is not detected stops the wireless remote control system 1 is intended to operate the security applications device 4a, in terms other than these are similar to the fourth referential embodiment Since it exists, description is abbreviate | omitted.

  The wireless remote control system 1 is provided with a security application device 4a, and when the human body detection device 6 does not detect a human body, the transmitter 2 stops the transmission of the wireless remote control signal 5, and the receiver 3 receives the wireless remote control signal 5. When the operation of the controlled device 4 is stopped and the security application device 4a is operated and the human body detection device 6 detects the human body during the period during which it cannot be sensed, the transmitter 2 sends out the wireless remote control signal 5 and the receiver 3 When the wireless remote control signal 5 is received, the controlled device 4 is operated and the security application device 4a is stopped.

  When the wireless remote control signal 5 from the transmitter 2 cannot be received for a predetermined period or longer, the receiver 3 determines that the transmission of the wireless remote control signal 5 is stopped and controls the controlled device 4 to be controlled. A control signal 34 for turning off the power of the device 4 is sent, while a control signal 35 for turning on the power is sent to the security application device 4a.

The controlled apparatus 4, similar to those of the fourth reference embodiment, and the like a want to operate at room equipment for example the air-conditioning equipment and lighting equipment and television receivers. The security application device 4a is a kind of controlled device, and is a device for crime prevention measures that is not desired to operate when the person is present but is desired to operate when the person is absent. As an example of such a security application device 4a, there is a security system for a sensor that detects opening / closing of a window and an alarm device that unconditionally generates a loud sound when a window is opened based on a detection result of the sensor. In the case of this security system, even if there is a regular owner, as soon as the window is opened carelessly, the alarm is issued at a loud volume, so it becomes annoying in the neighborhood.

Next, the operation of the wireless remote control system 1 will be described with reference to FIG. Compared to the fourth reference embodiment, steps S19 to S24 are the same determination process, and thus description thereof is omitted. After step S24, the receiver 3 not only sends a control signal 34 "turning on the power of the controlled device 4" to the controlled device 4, but also turns off the power of the security application device 4a. A control signal 35 indicating "Yes" is also sent (step S25-1). The controlled device 4 that has received the control signal 34 turns on the power of the controlled device 4 itself, and the security application device 4a that has received the control signal 35 turns off the power of the security application device 4a itself (step S26-). 1). Thereafter, while the transmitter 2 and the human body detection device 6 return to operation immediately before step S19, the receiver 3 is not shown in the flowchart of FIG. The operation is shifted immediately after the standby state (step S5) in the reference form.

On the other hand, the determination process for branching to step S27 is the same determination process from step S27 to step S30 as compared to the fourth reference embodiment, and thus the description thereof is omitted. After step S30, the receiver 3 not only sends a control signal 34 "turning off the power of the controlled device 4" to the controlled device 4, but also turns on the power of the security application device 4a. A control signal 35 indicating “Yes” is also sent (step S31-1). The controlled device 4 that has received the control signal 34 turns off the power of the controlled device 4 itself, and the security application device 4a that has received the control signal 35 turns on the power of the security application device 4a itself (step S32-). 1). Thereafter, while the transmitter 2 and the human body detection device 6 return to operation immediately before step S19, the receiver 3 is not shown in the flowchart of FIG. The operation is shifted immediately after the standby state (step S5) in the reference form.

  The wireless remote control system 1 configured as described above can restart the operation device for use in the room when the receiver 3 detects the wireless remote control signal 5. Therefore, when the controlled device 4 is a room-time operation application device that is not desired to be operated when no person is present, the room-time operation application device can be automatically stopped when no person is present.

  Furthermore, since it is not necessary to transmit the wireless remote control signal 5 in an unattended room (a state in which the human body detection device 6 does not detect a human body), the power required for transmitting the wireless remote control signal 5 can be eliminated, thereby saving energy.

It is a system configuration figure of the 1st reference form. It is a flowchart same as the above. It is explanatory drawing of the 2nd reference form. It is a flowchart same as the above. It is explanatory drawing of the 3rd reference form. It is a flowchart same as the above. It is a system configuration figure of the 4th reference form. It is a flowchart same as the above. It is a system configuration figure of an embodiment of the invention It is a flowchart same as the above. This is a remote control receiving apparatus described in Japanese Patent No. 3289022.
