As an automatic lighting/extinguishing control device for lighting in residences, etc.,
Conventionally, there is one described in Japanese Utility Model Application Publication No. 63-23800.

This type of frill <B device has a human body detection sensor, and when a human body is detected, it transmits a signal wirelessly to turn on a lighting lamp.

[Problems to be Solved by the Invention] If this automatic lighting on/off control device is applied to stairway lights in a three-story house, when going from the second floor to, for example, the first floor, not only the first floor stairway lights; It was inconvenient and uneconomical that even the stairway lights on the third floor were lit.

In addition, since the lighting is controlled based only on the presence or absence of a human body, even if the illuminance of the lighting control area, such as the staircase space, is sufficient,
When a person enters the stairway space, there is an uneconomical problem in that the stairway lights turn on.To prevent this, it is necessary to turn off the switch during the daytime when there is sufficient illuminance, although it may be troublesome. equipment must be kept inoperable,
In addition, since the human body detection range is not specified, it is inconvenient to use in various parts, and in cases where a low-intensity backup light is required before a person enters the lighting control area. There was a problem in that it required manual operation of the standby light switch, making it impossible to achieve a switchless system.

The present invention has been made to solve the above problems, and has three
In buildings with more than one story, it is possible to automatically select and turn on only the stair lights that need to be turned on from among multiple stair lights, and furthermore, this lighting can be done according to the illuminance of the stair space. It is an object of the present invention to provide an automatic lighting/extinguishing control device that is economical, has excellent workability, and can realize switchless operation even when a standby light is required.

Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention includes: a first receiving unit that controls the first floor stairway light with a human body detection area near the doorway of the first floor stairs; a second receiving unit that controls the second floor stair light with a human body detection range near the warehouse entrance; and a third receiver that controls the third floor stair light with the human body detection range near the exit of the second floor stairs; A first transmitter having a human body detection range in the middle of the first floor stairs, and a second transmitter having a human body detection range in the middle of the second floor stairs, each of the transmitters having a human body detection range for which it is responsible. When a person enters, each receiver transmits a wireless signal with a unique signal identification code, and each receiver transmits the wireless signal when it detects a person entering the human body detection range for which it is responsible. When receiving a wireless signal whose signal identification code matches a setting code set in advance, the corresponding stairway light is turned on for a certain period of time. The second and third receivers monitor the illuminance of the illumination area of the first floor stair light, second floor stair light, and third floor stair light, respectively, and if the illuminance is higher than the set illuminance, the second and third receiving sections If the light is turned off, and the illuminance is lower than the above setting, the stair light in charge is turned on at a low brightness, and if a wireless signal addressed to itself is received, the stair light in charge is turned on at a low brightness. Under this condition, the stairway lamp was configured to be lit at high brightness.

1 Effect] In the present invention, when a person comes to the stairwell entrance or exit, the stairway light on that floor is automatically turned on for a certain period of time, and when the person comes halfway up the stairs,
The stairway light on the floor where the person is heading will automatically turn on for a certain period of time. In addition, when the illuminance of the bright area of the stairway light becomes low due to sunset, etc., the stairway light will automatically turn on at a low brightness, and in this state, the stairway light will automatically turn on at a low brightness. Alternatively, when a person stands at the exit of the stairs on the third floor, the first floor stair light, second floor stair light, or third floor stair light lights up at high intensity, and when a person comes to a specified area in the middle of the first floor stairs, the first floor stair light lights up. When the stair light and the 2nd floor stair light, which are in a low brightness lighting state, turn on at high brightness and come to a designated area in the middle of the 2nd floor stairway, the 2nd floor stair light and the 3rd floor stair light will turn on. Staircase lights that are lit at low brightness now turn on at high brightness. Then, the stair light that has been turned on at high brightness will turn off after a certain period of time has elapsed.

In FIG. 2, a human body detection sensor 21 generates a detection signal when a person enters the human body detection range, and this detection signal is amplified by an amplifier circuit 22 and then inputted to a level determination circuit 23. This level determination circuit 23 determines that what has entered the human body detection range is a human body when the level of the human power signal is equal to or higher than a set level, and generates a human body detection signal. 21 to 23 constitute a human body detection unit. This human body detection signal becomes an i-trigger signal of the timer circuit 24, and upon receiving the human body detection signal, the timer circuit 24 sends a drive signal to the oscillation circuit 25 for a minute time Δt.

31 to 33 constitute a human body detection unit.

Reference numeral 35 denotes an illuminance sensor that monitors the illumination area of the stairway light and sends an illuminance signal of a level corresponding to the surrounding brightness to the level determination circuit 35. The level determination circuit 35 generates a low illuminance signal when the level of the input signal is below a set level (illuminance), and generates a high illuminance signal when the level of the input signal is above the set level (illuminance). 34 and 35 constitute an illuminance detection unit.

37 is a control circuit (consisting of a microcomputer) CP
U, upon receiving the low-intensity signal, gives a low-intensity command signal to the drive circuit 40 to turn on the stairway light at low intensity;
''-When the high illuminance signal is received, a lights-off command signal is given to the drive circuit 40 to turn off the stairway light. The judge circuit 37 is
While receiving the low illuminance signal, (a) upon receiving a human body detection signal from the level determination circuit 33, an operation is performed to send a high brightness lighting command signal to the drive circuit 40 for a certain period of time To; ) Decipher the radio signal received by the receiving circuit 38 via the antenna 39, determine whether the identification code of the radio signal matches the reception identification code set in the identification code setting N34, and determine whether they match. If so, an operation is performed in which a high-intensity lighting command signal is sent to the drive circuit 40 for a certain period of time To (this time To will be described later).

The drive circuit 40 lights the illumination lamp at high brightness while receiving the high brightness lighting command, and when the high brightness lighting command disappears,
Turn on the lighting lights at low brightness.

The receiving unit R1 controls the lighting of the illumination lamp 16, and the human body detection sensor 31 detects a detection range B near the metal eye ↓ 4A of the stairs 14.
1, and the illuminance sensor 34 monitors the illuminance of the illumination area of the one-stage light 16. In addition, the identification code setting device 34 is C0D
Set E-1.

The receiving unit R2 controls the lighting of the stair light 17, and the human body detection sensor 31 has a detection range B near the gold eye 15A of the stairs 15.
2, and the illuminance sensor 34 monitors the illuminance of the illumination area of the stair light 17. Further, the identification code setting device 34 is C0
Set DE-1 and C0DE2. The receiver R3 controls the lighting of the stair light 18, the human body detection sensor 31 has a detection range B3 near the exit 15B of the stairs 15, and the illuminance sensor 34 monitors the illuminance of the illumination area of the stair light 18.

Further, the identification code setter 34 sets C0DE-2. Note that, as shown in FIG. 4, the drive circuit 40 includes, for example, a 1-RIAC 43 that controls the phase of the voltage of the AC type fAAC, a photocoupler 42 that provides a get signal to the TRIAC 43, and a voltage zero point passage timing of the AC power source AC. It has a zero cross detector 41 that detects.

Next, the operation of the apparatus of this embodiment will be explained with reference to the waveform time chart of FIG. 5 and the operation flow chart of FIG. 6.

It is assumed that a person M goes down the stairs from the third floor 3F to the first floor IF.

When the illuminance of the illumination area of each staircase light 16 to 18 is sufficient, such as during the daytime, the output of the illuminance sensor 35 of each receiving section R1 to R3 is at a high level, and the output of the level determination circuit 36 is 1. level, the control circuit 37 generates neither a low brightness lighting command signal nor a high brightness lighting command signal, and the stair lights 16 to 18 are turned off.

When the illuminance of the illumination area falls below the set illuminance after sunset, the level determination circuit 36 generates a low illuminance signal, so the control circuit 37 synchronizes the low brightness lighting command signal with the output of the zero cross detector 41. The photocoupler 42 of the drive circuit 40
Send to. This causes the triac 43 to reach the firing phase α
, (for example, electrical angle 150°) ONL, stair light 16~
18 lights up at low brightness.

Assume that it is now nighttime and the stair lights 16, 17 and 18 are in the low-intensity lighting state.

(a) Person M is at the exit 15 of the stairs 15 as shown in FIG.
When reaching point B, the human body detection sensor 31 of the receiving section R3 detects the person M, so the level determination circuit 36 of the receiving section R3 generates a human body detection signal and inputs it to the control circuit 37. At this time,
Since the stair light 18 is in a low-intensity lighting state, the control circuit 37 of the receiving section R3 provides a high-intensity lighting command signal to the drive circuit 40. The high-brightness lighting command signal is sent to the photocoupler 42 of the drive circuit 40 in synchronization with the output of the zero-cross detector 41, and at the same time, a timer section (not shown) of the control circuit 37 (set time To) starts measuring time. As a result, the triac 43 has an ignition phase αu (for example, an electrical angle of 300<C6>
ONI, the stair light 16 lights up with high brightness. As a result, the output of the illuminance sensor 35 changes to the H level for the set time T.

Until the above timer section counts up after
The control circuit 37 continues to send out the high-intensity lighting command signal, and the stair light 18 maintains the high-intensity lighting state.

As a result, the upper half of the stairs 15 is sufficiently illuminated, and the person M
can safely descend stairs 15 toward landing 15C.

Note that when the set time To has elapsed, the control circuit 37 stops sending out the high-intensity lighting command signal.

As a result, the illuminance of the illumination area of the stair lamp 18 falls below the set illuminance, so the control circuit 37 sends a low brightness lighting command signal to the drive circuit 40, and
will switch to low brightness lighting.

This set time To is set to the time required for the person M to sufficiently pass through the landing from the top or exit of the stairs 14 and 15.

(b) When the person M comes down to the vicinity of the landing 15C of the stairs 15, the human body detection sensor 21 of the transmitter T2 detects the person M, so the level determination circuit 23 generates a human body detection signal, and the transmitter T2 , during the minute time Δt, the identification code C0D
A signal S2 with E-2 is sent out.

(C) Since this signal S2 has the identification code C0DE-2, the control circuit 37 of the receiving section R3 and the control circuit 37 of the receiving section R2 determine that the signal is addressed to itself.

Since the stair light 17 is in a low brightness lighting state, the control circuit 37 of the receiving unit R2 sends a high brightness lighting command signal to the drive circuit 40, and the drive circuit 40 operates as described above to turn on the stair light 17. Turn on high brightness.

At this time, the control circuit 37 of the receiving section R3 resets the timer section and starts counting again, and sends a high-brightness lighting command signal to the drive circuit 40 until the time To has elapsed from this timing.
Send to. Therefore, the high-intensity lighting state of the stair light 18 is extended by the time To (of course, the high-intensity lighting state may not be extended without responding to the signal S2).

In this way, when the person M comes near the landing 15C of the stairs 15, the stair light 17 lights up with high brightness, illuminating the stairway space of the stairs 15 with high brightness, until the person M passes through the landing 15C.
Since the stair light 18 continues to be lit, Person M can safely reach the 2nd floor.
You can go down to

(d) When the person M stands on the metal eye 15A of the stairs 15, the human body detection unit 1- of the receiving section R2 generates a human body detection signal and inputs it to the control circuit 37. At this time, the stair light 17 is lit with high brightness, but the control circuit 37 resets the timer unit (not shown) and starts counting a new time To, and from this timing until the time To has elapsed, Continue sending the high brightness lighting command signal.

(e) Furthermore, when going down to the 1st floor IF, use the ff of stairs 14.
+ri When the person comes near the landing area 14C, the human body detection sensor 21 of the transmitter Tl detects the person M, so the level determination circuit 2
3 generates a human body detection signal, and the transmitter 1''l sends out a radio signal S1 having an identification code 1'' COD E-1.

(f) Since this radio signal S1 has the identification code C0DE-1, it is determined that the signal is addressed to either the control circuit 37 of the receiving section R2 or the control circuit 37 of the receiving section R1. Receiver R
Since the stair light 16 is in a low-intensity lighting state, the control circuit 37 of No. 1 sends a high-intensity lighting command signal to the drive circuit 40,
The stair light 16 is turned on with high brightness. This ensures that the stairs 14 are sufficiently illuminated. At this time, the control circuit 37 of the receiving section R2 resets the timer section and starts counting again, and sends a high-intensity lighting command signal to the drive circuit 4o until the time To has elapsed from this timing.

Therefore, the stair light 17 remains in a high-intensity lighting state for a period of time T.

(Of course, the high brightness lighting state may not be extended without responding to the signal s1).

The above is an explanation for when a person goes down the stairs, but the same applies when a person goes up the stairs.
4A, the stair light 16 lights up with high brightness, and when this person M comes to the upper half of the stairs 14, the stair light 17, which is in the low brightness lighting state, lights up with high brightness, and when the person M comes to the upper half of the stairs 14 When this happens, the stair light 18, which has been in a low-intensity lighting state, shifts to high-intensity lighting.

As described above, in this embodiment, when a person M stands at the stairwell entrance or stairway exit on each of the seven floors at night, the receiving units R1 to R switch the stairway lights of the stairs from bottom brightness lighting to high brightness lighting.
3, so you can safely start climbing or descending the stairs.

Furthermore, a transmitter Tl that detects a human body and transmits a wireless signal S1 is provided in the middle of the stairs 14 connecting the first floor 11 and the second floor 12, and this wireless signal S1 causes the stair light 16 on the first floor and the second floor to be connected. Among the stair lights 17, the stair lights 17 that are lit at low brightness are turned on at high brightness, and furthermore, a human body is detected in the middle of the stairs 15 connecting the second floor 12 and the third floor 13, and a wireless signal S2 is transmitted. A transmitter T2 is provided, and the wireless signal S2 transmits the stair light 1 on the first floor.
Among the stair lights 18 on the 7th and 2nd floors, the stair lights 18 that are lit at low brightness are turned on at high brightness, so that the stair lights on the floor that person M is trying to climb or descend from are the same as those on the floor that person M is trying to climb or descend from. Before reaching the floor, the high-intensity light is automatically turned on, just like a guide light, illuminating the part of the stairs that are to be climbed and the part of the stairs that are to be descended, so that person M can safely climb to the next floor. You can get off.

Further, for example, while the control circuit 37 of the receiving section R3 sends out a high-intensity lighting command signal and the stair light 18 is turned on at high intensity, another person comes to the stairway exit 15B and the human body of the receiving section R3 is turned on. When the detection unit generates a human body detection signal, the timer section of the control circuit 37 is reset and starts counting again, and the stair light 18 that has been turned on at high brightness is further turned on at high brightness for the set time To. Therefore, even if someone else starts going down the stairs while person M is in the middle of the stairs 15, the stair light 18 will be turned off before the person who started going down later finishes going down the stairs 15. There is no such thing as the light going out.

Further, the transmitter TI located in the middle of the stairs 14 is, for example, 1
When a person M enters the detection range of a person going from the floor 11 to the second floor 12, a signal S1 is sent to the receivers R1 and R2 to not only turn on the low-intensity stair light 17, but also to Since the high-intensity lighting time of the stair light 16 that is lit at high brightness is extended, even when a person M who has climbed to the upper half of the stairs 14 returns to the first floor 11, the stair light 16
does not switch to low brightness lighting. 2nd floor 12-1
The same applies when going down to the floor 11 and when going up and down the second floor 12 and the third floor 13.

In addition, in this embodiment, when the illuminance of the stair space becomes low, the stair light turns on at a low intensity and serves as a backup light, and in this state, when a person stands at the stairwell entrance or stairway exit, The lights turn on with high brightness and there is no need to operate a switch, so you can go up and down the stairs safely and smoothly.

In addition, when a certain period of time To elapses after the stair light is turned on,
Since the light turns off automatically, there is no need to forget to turn it off, and unnecessary power consumption can be avoided.

Further, since the transmitting units TI and T2 communicate with the receiving units R1 to R3 by wireless signals, no wiring is required, and the workability of the device is improved.

Further, in the above embodiment, the illuminance of each illumination area of the stair lights 16 to 18 is low, that is, the stair lights 16 to 18 are switched to high brightness lighting on the condition that they are lit at low brightness. Receiving units R1 to R3 without considering the illuminance of the above illumination area.
The stair lights 16 to 18 may be simply turned on when a person enters the human body detection range and receives a radio signal addressed to the stairway lights 16 to 18, respectively.

Furthermore, the present invention is not limited to three-story houses;
Similar effects can be obtained by applying the present invention to stair lights in houses with four or more floors, and the stairway to which it is applied is not limited to curved stairs.

Note that the wireless signals (radio waves, infrared rays, etc.) sent by the transmitters T1 and T2 are made into a combination of logical signals of a certain length when there is a possibility of interference with other signals.

〔Effect of the invention〕

As explained above, when a person comes to the stairwell entrance or exit, the stairway light on that floor is automatically turned on for a certain period of time, and when the person comes in the middle of the stairs, the stairway light on the floor the person is heading towards is turned on automatically. will automatically turn on for a certain period of time, which prevents the stairway lights from being turned on unnecessarily.Furthermore, when the illuminance of the lighting area becomes low due to sunset, etc., the stairway lights will turn on at low brightness. It serves as a backup light, and in this state, if someone comes to the stairway entrance or stairway exit, the stairway light will turn on at high brightness, and when the person is halfway up the stairs, the stairway light for the floor they are about to go will turn on at high brightness. These high-intensity lighting conditions continue until the person finishes passing through the illumination area (21) above. too,
Using one stair light for each floor, lighting control according to the movement of people can be achieved completely without switches.
