  FIG. 3 shows a specific configuration of the power supply circuit 56. The commercial AC power supply 17 is supplied to the primary coil of the high power transformer 41 via the contactless relay 27. The high power transformer 41 steps down the commercial AC power supply 17 to a required voltage and outputs it from the secondary coil. The AC output voltage of the high power transformer 41 is converted into a DC voltage by the rectifier circuit 43 and the stabilization circuit 44 and supplied to the motor drive circuit 32.

  The non-contact relay 27 supplies the commercial AC power supply 17 to the high power transformer 41 when the power supply signal PS is input from the microcomputer 31 in the normal mode, and when the power supply signal PS is not input, The supply of the commercial AC power supply 17 to the transformer 41 is cut off.

  The control devices 64 and 66 of the LED lighting fixture 61 and the air conditioner 62 include a power supply circuit similar to the blind controller 7. That is, in the LED lighting device 61, the microcomputer power supply MD is supplied to the microcomputer that controls the lighting operation, and power is supplied to the LED drive circuit via the power supply unit similar to the contactless relay 27 and the power supply circuit 56.

  In the air conditioner 62, the microcomputer power supply MD is supplied to the microcomputer that controls the air conditioning operation, and the power is supplied to the air conditioner drive circuit through the same power supply unit as the contactless relay 27 and the power supply circuit 56. The operation of these power supply units in the energy saving mode is the same as the operation of the blind controller 7 in the energy saving mode.

  Next, the operation of the power controller 4 will be described with reference to FIGS. The power controller 4 controls each electric horizontal blind 5 in either the normal mode or the energy saving mode based on the command signal output from the command source 12.

  In the normal mode, the microcomputer power MD is supplied from the power interface 51 of the power controller 4 to the microcomputer 31 via the microcomputer power input terminal 54 and the power stabilization circuit 55 of the blind controller 7. Then, the power supply signal PS is input from the microcomputer 31 to the contactless relay 27, and the contactless relay 27 becomes conductive, and the commercial AC power supply 17 is supplied to the primary coil of the high power transformer 41. In this state, the motor drive circuit 32 is operated based on the command signal output from the command source 12, and the slat 11 is moved up or down or the angle is adjusted.

  In such a normal mode, as shown in FIG. 4, the microcomputer 15 of the power supply controller 4 monitors whether or not a command signal is received in the normal mode from the command source 12 (step 1).

  When a command signal for the controlled object, that is, the electric horizontal blind 5 connected to the power controller 4 is input from the command source 12 to the power controller 4, the command signal is a command signal for shifting to the energy saving mode (step 2). 3), the process proceeds to step 4.

If a command signal for shifting to the energy saving mode is not input in steps 2 and 3, the process proceeds to step 1 to monitor reception of the command signal.
In step 4, upon receipt of the command signal in the energy saving mode, it is scanned whether or not the electric horizontal blind 5 to be controlled is in the up / down operation or the angle adjustment operation. When the elevating operation and the angle adjusting operation are stopped (step 5), a data scan command is output to the electric horizontal blind 5 to be controlled (step 6).

  Then, the microcomputer 31 of the blind controller 7 of each electric horizontal blind 5 scans the current data such as the slat height and the slat angle, transmits the scan result to the power controller 4 and stores it in the EEPROM 38.

  Next, the microcomputer 15 of the power supply controller 4 performs power supply cutoff control on the electric horizontal blind 5 to be controlled (step 7). That is, the microcomputer 15 of the power supply controller 4 stops the output of the microcomputer power supply MD from the power supply interface 51. At this time, after the power supply signal PS is stopped by the control of the microcomputer 31 by the blind controller 7 and the supply of the commercial AC power supply 17 to the power supply circuit 56 is cut off, the supply of the microcomputer power supply MD is cut off.

  Then, in the blind controller 7 of the electric horizontal blind 5 to be controlled, the non-contact relay 27 is turned off, and the supply of the commercial AC power supply 17 to the primary coil of the high power transformer 41 is cut off. As a result, power consumption in the blind controller 7 is eliminated.

  Next, the microcomputer 15 of the power supply controller 4 stores the current data received in step 6 in the EEPROM 22 (step 8), and further transmits the current data to the command source 12 (step 9), so as to shift to the energy saving mode. Exit.

In the energy saving mode, as shown in FIG. 5, the microcomputer 15 of the power controller 4 monitors whether or not a command signal is received from the command source 12 in the energy saving mode (step 11).
In this state, a command signal for the controlled horizontal blind 5 connected to the control target, that is, the power controller 4 is input from the command source 12 to the power controller 4. If the command signal is a signal for commanding data scanning (steps 12, 13, and 14), the microcomputer 15 proceeds to step 15 and reads the current data of each electric horizontal blind 5 stored in the EEPROM 22. , To the command source 12 (step 16).

  When a signal for instructing the controlled object to cancel the energy saving mode is input in steps 12 and 13, the process proceeds to step 17 to determine whether or not a blind operation command signal is included in the command signal.

If an operation command signal is included, the operation command signal is temporarily stored in the RAM 21 (step 18).
Next, the process proceeds to step 19 where control is performed to release the interruption of power to the electric horizontal blind 5 to be controlled. That is, the microcomputer 15 of the power supply controller 4 resumes the output of the microcomputer power supply MD from the power supply interface 51.

  Then, in the blind controller 7 of the electric horizontal blind 5 to be controlled, the non-contact relay 27 becomes conductive, and the commercial AC power supply 17 is supplied to the primary coil of the high power transformer 41. As a result, the blind controller 7 enters a normal mode in which power is supplied to the motor drive circuit 32 and the microcomputer 31.

  Next, in step 20, the operation command signal stored in the RAM in step 18 is output to the electric horizontal blind 5 to be controlled. Then, the electric horizontal blind 5 to be controlled drives the slat 11 based on the operation command signal, and when the control operation of the slat 11 is completed, the current data of the electric blind 5 is stored in the EEPROM 38.

  Next, in step 16, the power supply controller 4 reads the current data from each electric horizontal blind 5 to be controlled, stores it in the EEPROM 22, and transmits it to the command source 12.

  In step 17, if the command signal does not include the blind operation command signal, the process proceeds to step 19 where control is performed to release the power supply to the electric horizontal blind 5 to be controlled. Then, without performing the process of step 20, the current data is read from each electric horizontal blind 5 to be controlled and stored in the EEPROM 22 and transmitted to the command source 12 in step 21.

FIG. 6 shows the operation of the microcomputer 31 of the blind controller 7 when shifting from the normal mode to the energy saving mode.
In the normal mode, the microcomputer 31 constantly monitors the command signal input from the communication port 34 (step 41). If the input command signal is an energy saving mode command for the blind controller 7 (steps 42 and 43), the microcomputer 31 indicates that the motor 10 is operating based on the previous operation command signal. Control is performed up to a position based on the command signal (step 44).

Thereafter, the contactless relay 27 is controlled to cut off the supply of the commercial AC power supply 17 to the power supply circuit 56 (step 45).
Next, the current data such as the slat height and slat angle is scanned, the scan result is stored in the EEPROM 38 (step 46), and when the data scan command is received from the power supply controller 4 (step 47), it is stored in the EEPROM 38. The current data is transmitted to the power supply controller 4 (step 48).

  In the control devices 64 and 66 of the LED lighting device 61 and the air conditioner 62, the power supply operation and the cutoff operation similar to the blind controller 7 are performed based on the operation of the power controller 4.
