Is provided similarly to the parent device 1.

The control circuit unit 307 is constituted by a microcomputer, and detects the presence or absence of a human body obtained from the terminal unit 333 via the slave unit line signal detection circuit unit 300 according to the switching setting of the changeover switch 306, and the sensor circuit unit. The power supply control to the load connected to the load terminal unit 332 is performed using the detection result of 301.

For example, when the control circuit 307 is set to “automatic” by the changeover switch 306, the terminal 33
3 and at least one of the sensor circuit units 301, the operation holding time set by the operation holding time setting volume 302, the opening / closing unit 304

Or, in the case of “bright”, if the detection result of the illuminance by the brightness sensor unit 103 is lower than the corresponding predetermined illuminance,
The above operation is allowed. That is, when the surrounding illuminance is darker than the predetermined illuminance, each time the detection result of the presence of the human body is obtained, the lighting fixture 4 is turned on for the corresponding operation holding time. On the other hand, if the detection result of the illuminance by the brightness sensor unit 103 exceeds the corresponding predetermined illuminance, the load terminal unit 1
Since the supply of the electric power obtained from the power supply terminal unit 131 to the power supply terminal 32 is prohibited, the lighting fixture 4 does not turn on but remains off. This makes it possible to operate only the ventilation fan 5 without turning on the lighting fixture 4 during the daytime when the surrounding illuminance is brighter than the predetermined illuminance, for example.

Since the main ventilation fan 3 can be connected to the terminal unit 133 of the main unit 1 together with the conventional sub unit 2, the human body at a plurality of places by the plurality of sub units including the main unit 3 can be connected.

For example, the parent device 1 can be connected to 200V, and the ventilation fan 3 can be connected to 100V.

The present invention is not limited to this, and the power supply for the slave unit line signal detection circuit unit 300 and the sensor circuit unit 301 in the ventilation fan 3 may be taken from the power supply terminal unit 331. In the case of this configuration, since both the sensor circuit unit 301 and the control unit 307 can be driven by a power supply different from that of the main unit 1, the ventilation fan 3 is connected to the commercial power supply AC, and the load terminal unit 332 is connected.

(Eighth Embodiment) FIG. 29 is a diagram showing an automatic switch system including a parent device, a child device, and a ventilation fan, FIG. 30 is an explanatory diagram of the operation of the system of FIG. 29, and FIG.
9 is a circuit configuration diagram of a parent device in No. 9, and an eighth embodiment of the present invention will be described with reference to these drawings.

As described in the last paragraph of the first embodiment, the automatic switch system shown in FIG. 29 detects the detection result of the sensor circuit unit 101 from the slave terminal 133 through the slave signal transmission / detection circuit 100. Output to the outside,
It is characterized in that the control circuit unit 107 of the parent device 1 is configured.

However, in the case of this configuration, the slave unit signal transmission /

3 is transmitted.

In the example of the circuit configuration shown in FIG. 31, when the control circuit section 107 receives the detection result of the presence of a human body from the pyroelectric element 101a constituting the heat ray sensor of the sensor circuit section 101, it outputs a signal including the detection result of the presence of a human body. An ON signal is output to the slave unit signal sending / detecting circuit unit 100 as a sending instruction.

Heretofore, the ceiling-mounted type automatic switch with a heat ray sensor conventionally performs a load control of 2, 3 A using a relay and a semiconductor element assuming a general house. Up to two slave units can be connected, and the extension of the human body detection area is limited.
