Automatic switch system with human body sensor

The present invention relates to an automatic switching system for a human body sensor that controls the illumination/deactivation of a lighting load by detecting the presence of a human body by a hot line or the like.

In the past, in order to control the lighting/extinguishing of the lighting load, an automatic switch with a hot wire sensor was used. In the automatic switch of the hot-line sensor, when the hot-line sensor detects a person, the lighting load is turned on during the operation holding time (for example, refer to Patent Document 1). ).

In the automatic switch of the hot line sensor of Patent Document 1, the operation mode of the continuous lighting, the automatic lighting, and the forced extinguishing of the lighting load is switched by the pressing operation of the operating handle.

Moreover, as an automatic switching system of a hot-line sensor, there is known an illumination system including a switch, a slave, and an external device of a heat-wire sensor connected to a plurality of illumination loads (see Patent Document 2).

In the illumination system of Patent Document 2, each lighting load is turned on when power from a commercial power source is supplied via a switch of a heat-supply sensor. The handset has a hot line sensor having the same function as the hot line sensor of the switch with the hot line sensor, and is connected to the switch of the hot line sensor. Also, the external device outputs an external signal based on the user's operation. The open relationship of the attached hot line sensor is based on an external signal to illuminate and extinguish each lighting load.

The lid body 11b includes three first cylindrical protrusions 11bs having a rectangular shape in plan view along the short side direction of the lid body 11b in the central portion of the lid body 11b. The switch master 10 emits light that emits the unregistered diode 6a from the fifth aperture 11bj of the first cylindrical projection 11bs. The light from the light-emitting diode 6a emitted from the first cylindrical projection 11bs is radiated to the outside of the switch main unit 10 via the decorative cover portion 2g. The lid body 11b is on the lower side of the lid body 11b (on the right side of the sheet surface of Fig. 5), and includes a boss portion 11bk that protrudes from the outer side of the first surface 11bp side of the lid body 11b. The lid body 11b is provided with an opening 11bm in the boss portion 11bk.

Further, in order to rotatably mount the handle portion 2f of the manual operation portion 2a1, the lid body 11b includes a protruding shaft portion 11bn on one side wall side (the lower side of the paper surface of FIG. 5) of the first surface 11bp of the lid body 11b. The shaft portion 11bn is formed in a columnar shape along the longitudinal direction of the lid body 11b. As shown in FIGS. 5, 12, and 14, the lid portion 11b is pressed against the handle portion 2f side of the manual operation portion 2a1 by a spring leaf piece 2d made of metal. In other words, the manual operation unit 2a1 holds the shaft portion 11bn of the lid body 11b with the handle portion 2f and the spring piece 2d, and holds it in the body 11. Moreover, the lid body 11b is included in the center portion holding end portion of the first surface 11bp of the lid body 11b in plan view, and the other end side (the paper surface side in Fig. 5) is deflected by the T-shaped peripheral portion. Department 11br. The flexure portion 11br is configured to be deflected inside the body 11 by pressing from the handle portion 2f.

The first operation switch 2a is a piano handle in which one end portion of the handle portion 2f of the manual operation portion 2a1 is supported by the body 11 and the other end portion is rotatably pressed. That is, the first operation switch 2a constitutes a piano handle type switch. The piano handle type opening relationship is such that the piano handle attached to the front side of the switch main body 2aa is rotated by pressing the other side with one side of the piano handle as a fulcrum. The piano handle constitutes a part of a switch that can press the operating unit 2ac of the actuating switch body 2aa. The piano handle switch can be switched by touching the piano handle.

As shown in FIG. 12, the manual operation unit 2a1 is configured such that the T-shaped flexure portion 11br can be brought into contact with the operation unit 2ac. The manual operation unit 2a1 is in a state of being supported by the body 11, and the back side of the manual operation unit 2a1 can be in contact with the deflection portion 11br of the lid body 11b. When the user presses and operates the manual operation unit 2a1, the manual operation unit 2a1 is pressed against the lid body 11b side. The switch master 10 is pressed by the manual operation unit 2a1, and the manual operation unit 2a1 presses the operation unit 2ac inside the body 11 via the flexure 11br. The switch master 10 is electrically connected to the first operation switch 2a when the operation unit 2ac is pressed. The switch master 10 can be configured such that when the pressing force disappears from the manual operation unit 2a1, the manual operation unit 2a1 is restored to the original position by the reaction force of the operation unit 2ac. When the manual operation unit 2a1 returns to the original position, the first operation switch 2a is turned off. The first operation switch 2a can use, for example, a tactile sense switch.

As shown in FIG. 3, the switch master 10 is provided with a ridge portion 2g4 on the surface of the decorative cover portion 2g. In the switch master 10, the ridge portion 2g4 of the decorative cover portion 2g can be used as a symbol when the user operates the manual operation portion 2a1.

The switch mother machine 10 can be inserted into the handle portion by at least a part of the first cylindrical protrusion 11bs The through hole 2f3 of 2f allows the light from the light emitting diode 6a to be efficiently irradiated to the outside. Further, the switch master 10 can suppress the light from the outside from being introduced into the inside of the body 11 and absorbed. Therefore, when the light-emitting diode 6a is turned off, the switch mother machine 10 can be darkened by the external light suppressing portion of the decorative cover portion 2g from which the light is emitted from the light-emitting diode 6a.

Further, in the switch master 10, as shown in FIG. 10, the handle portion 2f includes a second cylindrical projection 2fs that protrudes from the body 11 side and surrounds the first cylindrical projection 11bs. In the switch master 10, the light from the first cylindrical projection 11bs can be prevented from leaking between the manual operation portion 2a1 and the lid 11b by the second cylindrical projection 2fs despite the operation of the manual operation portion 2a1. Thereby, the switch base unit 10 can illuminate the light from the light-emitting diode 6a more efficiently on the side of the decorative cover portion 2g. Further, in the switch master 10, the body 11 includes a third cylindrical projection 11bt that protrudes to the inside so as to surround the light-emitting diode 6a. Thereby, the switch master 10 can suppress the diffusion of light from the light-emitting diodes 6a inside the body 11, and can efficiently emit light from the light-emitting diodes 6a to the outside of the body 11.

In the switch master 10, the control unit 4 incorporates a timer unit (not shown) for timing the lighting holding time at which the lighting load 52 is turned on. The control unit 4 is configured such that when the sensor signal is re-inputted from the hot line sensor unit 1 during the timing of the lighting retention time, the time from the re-input of the sensor signal is caused by the specific lighting retention time. The lighting load 52 is turned to the extinguished state. Therefore, the timer portion is constituted by a retriggerable timer to count the specific lighting retention time from the time point when the sensor signal is re-inputted.

As a basic operation, the control unit 4 is in a state where the brightness detected by the brightness sensor 1s is darker than a threshold value of a predetermined brightness, and the sense of human body detection is based on the change of the hot line incident on the heat line sensor unit 1. When the signal is measured, the illumination load 52 is illuminated. The threshold value of the brightness may be, for example, a memory (not shown) stored in the control unit 4. The control unit 4 controls the shutter 5 so as to maintain the lighting state of the illumination load 52 during the specific lighting retention time of the timer.

In the control unit 4, the sensor signal, that is, the output of the hot line sensor unit 1, is input. control The system 4 is input to the output of the first input determination unit 2. The control unit 4 is input to the output of the signal receiving unit 3. The control unit 4 detects whether or not a human body exists in a predetermined detection area based on the sensor signal from the hot line sensor unit 1, and outputs a control signal for controlling the shutter 5. The control unit 4 can be configured by, for example, a microcomputer including a CPU (Central Processing Unit).

The control unit 4 has an automatic lighting-off mode in which the illumination load 52 is automatically turned on based on the sensor signal from the hot line sensor unit 1, and the illumination load 52 is turned off after a specific lighting retention time. The control unit 4 has a continuous lighting mode in which the illumination load 52 is continuously turned on regardless of the presence or absence of a sensor signal from the hot line sensor unit 1. The control unit 4 has a forced-off mode in which the illumination load 52 is forcibly extinguished regardless of the presence or absence of a sensor signal from the hot line sensor unit 1.

The control unit 4 switches between the continuous lighting mode, the automatic lighting-off mode, and the forced-off mode by pressing the manual operation unit 2a1. The control unit 4 is electrically connected to each of the light-emitting diodes 6a. The control unit 4 individually controls the lighting of the plurality of light-emitting diodes 6a in accordance with each mode. The light-emitting diode 6a constitutes a mode display portion 6 capable of displaying each mode of the switch master 10, for example, by a light-emitting color or a lighting state. In other words, the control unit 4 can display each of the switched modes on the mode display unit 6 provided in the manual operation unit 2a1. Further, in the switch master 10 shown in Fig. 4, the continuous lighting mode is displayed as "continuous conduction". Further, in the switch master 10 shown in Fig. 4, the automatic light-off mode is displayed as "automatic". Further, in the switch master 10 shown in Fig. 4, the forced extinguish mode is displayed as "OFF".

Further, the switch master 10 switches the continuous lighting mode, the automatic lighting extinguishing mode, and the forced extinguishing mode each time the first operation switch 2a is operated. The mode display unit 6 displays "continuous conduction" in the continuous lighting mode. The mode display unit 6 displays "AUTO" in the automatic light-off mode. The mode display unit 6 displays "OFF" in the forced-out mode. In the switch master 10, according to the operation of the first operation switch 2a, "disconnect", "automatic", and "continuous guidance" The order of "pass" repeatedly switches each mode.

More specifically, in the forced extinguishing mode, the switch master 10 lights the light-emitting diodes 6a provided on one side in the short-side direction (the left side of the paper surface in FIG. 4), for example, in the three light-emitting diodes 6a. In the switch master 10, for example, among the three light-emitting diodes 6a, the light-emitting diodes 6a provided on one side in the short-side direction are lit in red. In the automatic light-off mode, the switch master 10 lights, for example, the light-emitting diode 6a provided at the center of the short-side direction. In the switch mother machine 10, for example, the light-emitting diodes 6a provided in the center portion in the short-side direction of the three light-emitting diodes 6a are lit in green.

The switch master 10 can also cause the light-emitting diodes 6a provided at the center portion to be turned on and off in green during a specific lighting retention time. In the switch master 10, the remaining time of the specific lighting holding time is reduced, and the interval between the light-emitting diodes 6a provided at the center portion is shortened. In the continuous lighting mode, the switch master 10 lights the light-emitting diodes 6a provided on the other side (the right side of the paper surface in FIG. 3) of the three light-emitting diodes 6a, for example. For example, in the three light-emitting diodes 6a, the switch mother machine 10 can illuminate the light-emitting diodes 6a on the other side in the short-side direction. In other words, the light-emitting diode 6a can perform the continuous lighting mode, the automatic lighting-off mode, and the forced-out mode in the display unit 6 by, for example, red light emission, green light emission, blue light illumination, or light-off. display.

The switch base unit 10 includes a decorative cover 1d on the lower side of the manual operation portion 2a1. The decorative cover 1d includes an opening window portion 1db at a position opposed to the opening 11bm of the lid body 11b. The decorative cover 1d is inserted into the boss portion 11bk such that the opening 11bm corresponds to the opening window portion 1db. The decorative cover 1d includes a projection 1dk that protrudes more than one surface 2ab of the manual operation portion 2a1. The projection 1dk has an arc shape in such a manner as to protect the projection portion 11bk.

The switch master 10 includes a setting operation unit 7 that can set the detection sensitivity of the hot line sensor unit 1. The setting operation unit 7 may have a function other than the detection sensitivity of the hot line sensor unit 1. The setting operation unit 7 may include an operation unit that can set the lighting holding time in the automatic lighting-off mode. The setting operation unit 7 exposes a part of the setting operation unit 7 to the body 11 The first surface is 11 bp. The setting operation unit 7 exposed to the first surface 11bp of the body 11 is covered by the manual operation unit 2a1. The setting operation unit 7 includes a first setting unit 7a and a second setting unit 7b.

The first setting unit 7a is attached to the first circuit board 16a such that the volume or the like of the first setting unit 7a. The first setting unit 7a is, for example, a first knob 7a1 including an operation shaft that can rotate the volume. The first setting unit 7a causes the first knob 7a1 of the first setting unit 7a to protrude from the first surface 11bp side of the body 11 via the third window hole 11bh of the body 11. The first setting unit 7a is configured to set a lighting holding time for lighting the lighting load 52 in the automatic lighting-off mode. The switch master 10 can appropriately set the lighting retention time in a range of, for example, 30 seconds to 30 minutes.

The second setting unit 7b is attached to the first circuit board 16a such that the rotation volume of the second setting unit 7b is set. The second setting unit 7b is, for example, a second knob 7b1 that includes an operation shaft that can rotate the rotation volume. The second setting unit 7b causes the second knob 7b1 of the second setting unit 7b to protrude from the first surface 11bp side of the body 11 via the fourth window 11bi of the body 11. For example, the second setting unit 7b can set the brightness sensitivity level of the brightness sensor 1s to be in a range from "dark" to "bright". The "dark" which is the brightness sensitivity level can be set to, for example, 5 lux or less. The "brightness" as the brightness sensitivity level can be set to, for example, 100 lux or more.

For example, when the second setting unit 7b is set to "OFF", the switch master 10 can stop the function of the brightness sensor 1s. When the second setting unit 7b is set to "OFF", the switch master 10 can prevent the indoor lighting load 52 from being turned on when the periphery of the switch main unit 10 is bright. When the switch master 10 is brighter around, the illumination load 52 in the room is prevented from being turned on, so that energy saving can be achieved.

In the switch master 10, for example, by adjusting the threshold value of the brightness by the second setting unit 7b, it is possible to obtain the same effect as the detection sensitivity of the setting hot line sensor unit 1 detecting that there is no one. In other words, in the switch master 10, the second setting unit 7b constitutes a setting operation unit 7 that can set the detection sensitivity of the hot line sensor unit 1. Further, the switch master 10 may include a setting operation unit 7 that is set by directly adjusting the detection sensitivity of the hot line sensor unit 1. The switch master 10 is a change in the amount of hot line detected by the hot line sensor unit 1 by, for example, adjusting the amplification based on the setting operation unit 7. The degree of amplification of the time can directly adjust the detection sensitivity of the hot line sensor unit 1.

In the system 30, the operation unit 20 shown in Fig. 15 is attached to the mounting frame 17, and is placed on a construction surface (not shown) such as a wall surface of a building. The operation unit 20 includes a case 21 that is embedded in a building material that is disposed on the construction surface. The operation slave unit 20 can be configured to include, for example, a case 21 in which the second input determination unit 22, the signal transmission unit 23, and the child machine control unit 24 can be housed. The casing 21 is configured to have the same structure as the attachment claws 11bd of the body 11 of the switch master 10, and can be attached to the mounting frame 17. The operation unit 20 includes a covering portion 22g that covers the front surface of the casing 21. The cover portion 22g can be used as a piano handle that constitutes the second operation switch 22a of the piano handle switch.

Next, the operation of the switch master 10 of the system 30 will be described in detail using FIG. 2.

When the switch master 10 is in the automatic light-off mode, when the transfer signal from the slave unit 20 is input to the control unit 4 via the signal receiving unit 3 at time t1, the control unit 4 controls the shutter 5 to set the illumination load 52 to Lights up. In the switch master 10, the control unit 4 gradually reduces the count value of the counter unit from the time when the transmission signal from the operation slave unit 20 is received until a predetermined time elapses. The switch unit 10 controls the shutter 5 to turn off the illumination load 52 after the time t2 when the counter value of the counter unit is "0". In other words, the switch master 10 lights the illumination load 52 before the lighting hold time from the preset time t1 to the time t2. In the following, the lighting holding time from time t1 to time t2 is also referred to as a first lighting holding time.

Further, in the switch master 10, although not shown, the sensor signal from the hot line sensor unit 1 is the same as the signal transmitted from the hot line sensor unit 1 in the case of the automatic light-off mode. The lighting load 52 can also be illuminated before the bright hold time.

Then, in the case where the switch master 10 is automatically turned on and off, the transfer signal from the slave unit 20 is input to the control unit 4 via the signal receiving unit 3 at time t3, and the control unit 4 controls the same as the time t1. The shutter 5 causes the lighting load 52 to be in a lighting state. When the switch master 10 is in the auto-lighting-off mode, when the hot line sensor unit 1 detects the initial heat at time t4 When the line changes, the hot line sensor section 1 outputs a sensor signal. When the switch master 10 inputs the sensor signal from the hot line sensor unit 1 during the lighting hold time, the lighting load is passed before the preset lighting hold time from the time t4 to the time t6 of the input sensor signal. 52 lights up. In the following, the lighting holding time from time t4 to time t6 is also referred to as a second lighting holding time.

The switch master 10 controls the shutter 5 to bring the illumination load 52 to the lighting state after the second lighting hold time. In FIG. 2, based on the input of the sensor signal, the control unit 4 sets the second lighting holding time in which the lighting load 52 is in the lighting state from time t4 to time t6. In the switch master 10, the first lighting holding time and the second lighting holding time are set to the same time interval, but the first lighting holding time and the second lighting holding time may be set to different time intervals. The switch master 10 sets the lighting hold time again by using the sensor signal as a trigger.

When the switch unit 10 receives the signal from the operator 20, the control unit 4 sets the count value of the counter unit to “0” at a time t3 after the time t3 when the illumination load 52 is turned on. T6, the control unit 4 controls the shutter 5 to set the illumination load 52 to the extinguished state. That is, it can be said that the switch master 10 extends the lighting holding time from the time t3 to the time t5 from the time t3 to the time t6.

Further, although not shown, when the switch master 10 is in the automatic light-off mode, the illumination load 52 can be turned on in the same manner as the signal is transmitted based on the sensor signal from the hot line sensor unit 1. Until the preset second lighting hold time elapses.

In the system 30, in the automatic lighting and extinguishing mode, by the operation unit 20 provided outside the detection area of the hot line sensor unit 1, regardless of whether or not the hot line sensor unit 1 of the switch unit 10 detects a person, The lighting load 52 can be kept lit during the lighting hold time. Further, in the system 30, the illumination load 52 is turned on by the operation unit 20, and the illumination load 52 can be maintained while the detection period of the hot line sensor unit 1 is detected and the lighting holding time is set again.

In the system 30, even if the detection area of the hot line sensor unit 1 in the switch base unit 10 is not Some people can also illuminate the lighting load 52. Therefore, for example, when the switch main unit 10 is placed in the porch, the system 30 can illuminate the illumination load 52 by operating the sub unit 20, thereby suppressing the state of walking to the hallway to keep the darkness. In the system 30, even if the switch master 10 is placed near the entrance, the illumination load 52 can be illuminated by the operation unit 20 provided at the other end of the corridor. Further, in the system 30, after the person intends to go out and operate the slave unit 20 to illuminate the lighting load 52, the lighting load 52 does not remain in the lighting state even if the user is removed from the switch master 10 by a telephone or the like. Therefore, the system 30 can achieve more energy saving.

In the system 30, for example, the person leaving the switch master 10 can stop the supply of power to the lighting load 52 by operating the slave unit 20. The signal receiving unit 3 in the switch master 10 receives the transmission signal from the operation unit 20, and the control unit 4 switches the supply of power to and from the illumination load 52 based on the transmission signal from the operation unit 20. When the switch master 10 supplies power to the illumination load 52 in the automatic light-off mode, for example, the power supply to the illumination load 52 can be continued by the sensor signal from the hot line sensor unit 1. When the control unit 4 causes the illumination load 52 to be in a lighting state during a specific lighting retention period by the transmission signal from the operation unit 20, the sensor signal from the hot line sensor unit 1 is used. The input is again re-timed for a specific lighting hold time. The control unit 4 can extinguish the illumination load 52 after a specific illumination hold time has elapsed from the input of the sensor signal from the hot line sensor unit 1.

In addition, the switch master 10 may be a second switch that includes on/off power supply to a load device such as a ventilating fan, in addition to the switch 5 that turns on/off the power supply of the lighting load 52. Composition. Thereby, the switch master 10 can also control a load machine different from the lighting load 52.
