(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. The electric blind system (electric solar shading system) shown in FIG. 1 is one in which a plurality of electric blinds are installed on each of a number of floors, and a personal computer or the like is connected to a floor controller 1 installed on each floor via a communication line 2a. Central control device 3 is connected.

  The floor controller 1 is connected to a power supply controller 4 through a communication line 2b, and the power supply controller 4 is installed in a head box 6 of an electric horizontal blind 5 installed on the floor through the communication line 2c. Connected to controller 7. The power controller 4 is connected to an operation switch 8 via a communication line 2d.

A commercial AC power supply 17 is supplied to the floor controller 1, the power supply controller 4, and the blind controller 7 through a distribution board 9.
The power controller 4 controls the power supply to the blind controller 7 of each electric horizontal blind 5 based on a command signal input from the central controller 3 or the operation switch 8 via the communication lines 2a and 2d. The operation of the blind controller 7 is controlled.

  A DC motor (hereinafter referred to as a motor) 10 controlled by the blind controller 7 is disposed in the head box 6. The blind controller 7 controls the motor 10 based on a command signal output from the power controller 4. Then, the slat (sunlight shielding material) 11 suspended from the head box 6 is lifted or lowered by the operation of the motor 10, or the angle is adjusted.

Next, the electrical configuration of the power controller 4 and the blind controller 7 will be described with reference to FIG.
In the figure, the command source 12 is the operation switch 8 or the central controller 3, and a command signal supplied from the command source 12 to the communication port 13 of the power controller 4 is input to the microcomputer 15 via the communication interface 14. Is done.

  A commercial AC power supply 17 is supplied to the power supply circuit 16 of the power supply controller 4 via a connector 18. The power supply circuit 16 converts AC power into DC power having a required voltage and supplies it to the microcomputer 15 and the relay power interface 19. Based on the drive signal output from the microcomputer 15, the relay power supply interface 19 supplies the DC power supplied from the power supply circuit 16 to the relay power output terminal 25 as the relay power RD and cuts off the supply. Controlled to either state.

  The microcomputer 15 operates based on a program stored in the ROM 20 and is connected to a RAM 21 for temporarily storing the processing result. The EEPROM 22 connected to the microcomputer 15 stores status information of each electric horizontal blind 5.

  The status display LED 23 connected to the microcomputer 15 displays the operation mode of each electric horizontal blind 5, that is, whether it is the normal mode or the energy saving mode. Further, the dip switch 24 connected to the microcomputer 15 can set address information of the power controller 4, address information of the electric horizontal blind 5 controlled by the power controller 4, and the like.

  The commercial AC power supply 17 is supplied to the blind controller 7 through a connector 26 and a contactless relay 27 to a power supply circuit 28. When the relay power RD is supplied from the relay power output terminal 25 of the power controller 4 via the wiring 29 and the relay power input terminal 30, the contactless relay 27 receives the commercial AC power 17 supplied to the connector 26. The power is supplied to the power circuit 28. That is, the non-contact relay 27 operates as a normally open contact that opens the contact when the relay power RD is not supplied.

  Further, the non-contact relay 27 has a known function of starting supply of AC power to the power supply circuit 28 at the timing at which the AC power supply voltage becomes the intermediate voltage based on the supply of the relay power supply RD, that is, the AC power supply voltage becomes an intermediate voltage. Yes.

  The power supply circuit 28 converts the commercial AC power supply 17 into a DC power supply having a required voltage and supplies it to the microcomputer 31 and the motor drive circuit 32. The motor drive circuit 32 controls the operation of the motor 10 based on the motor control signal output from the microcomputer 31.

A command signal supplied from the command source 12 to the communication port 34 of the blind controller 7 is input to the microcomputer 31 via the communication interface 35.
The microcomputer 31 operates based on a program stored in the ROM 36, and is connected to a RAM 37 for temporarily storing the processing result. The EEPROM 38 connected to the microcomputer 31 stores current data such as the slat height and slat angle of the electric horizontal blind 5.

  The state display LED 39 connected to the microcomputer 31 displays an operation mode of the electric horizontal blind 5, that is, whether it is a normal mode or an energy saving mode. The dip switch 40 connected to the microcomputer 31 can set address information and the like of the electric horizontal blind 5.

  FIG. 3 shows a specific configuration of the power supply circuit 28 of the blind controller 7. The power supply circuit 28 includes a high power transformer 41 for supplying an operating current to the motor drive circuit 32 and a low power transformer 42 for supplying an operating current to the microcomputer or the like. The commercial AC power supply 17 is supplied to the primary coil of the high power transformer 41 and the low power transformer 42 via the contactless relay 27.

  When the relay power RD is supplied, the contactless relay 27 supplies the commercial AC power 17 to the primary coil of the high power transformer 41 and the low power transformer 42. Therefore, when the relay power supply RD is not supplied, the commercial AC power supply 17 is not supplied to the primary coil of the high power transformer 41 and the low power transformer 42, so that the power in the high power transformer 41 and the low power transformer 42 is not supplied. Consumption is now gone.

  The high power transformer 41 steps down the commercial AC power supply 17 to a required voltage and outputs it. 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.

  Similarly, the low-power transformer 42 steps down the commercial AC power supply to a required voltage, and the stepped-down voltage is converted into a DC voltage by the rectifier circuit 45 and the stabilization circuit 46 and supplied to the microcomputer 31.

  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 relay power RD is supplied from the relay power interface 19 of the power controller 4 to the non-contact relay 27 of the blind controller 7, and the commercial AC power 17 is connected to the primary coil of the large power transformer 41 and the small power transformer 42. Have been supplied. Then, the motor drive circuit 32 operates 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).

  In this state, a command signal for the control target, 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, and the command signal is a command signal for shifting to the energy saving mode. (Steps 2 and 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 relay power supply RD from the relay power supply interface 19.

  Then, in the blind controller 7 of the electric horizontal blind 5 to be controlled, the contactless relay 27 becomes non-conductive, and the commercial AC power supply 17 is supplied to the primary coil of the high power transformer 41 and the low power transformer 42. Blocked. 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.

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 31). If the input command signal is a data scan command for the blind controller 7 (steps 32 and 33), the microcomputer 31 scans the current data such as the slat height and the slat angle, and the scan result is used as the power controller 4. (Step 34) and stored in the EEPROM 38 (step 35).

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 scan (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, Transmit 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 stops the output of the relay power supply RD from the relay power supply interface 19.

  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 and the low power transformer 42. 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.

In the electric blind system configured as described above, the following operational effects can be obtained.
(1) In the energy saving mode, the power supplied to the blind controller 7 of the electric horizontal blind 5 can be shut off. Therefore, it is possible to reduce power consumption in the electric horizontal blind 5 in the energy saving mode.
(2) In the energy saving mode, the power supply circuit 28 of the electric horizontal blind 5 uses the primary coil of the high power transformer 41 that supplies power to the motor drive circuit 32 and the small power transformer 42 that supplies power to the microcomputer 31 and the like. The supply of the commercial AC power supply 17 to the primary side coil can be cut off. Therefore, it is possible to eliminate power consumption in the large power transformer 41 and the small power transformer 42 in the energy saving mode.
(3) The power supply controller 4 can control the operation of the power supply circuit 28 of an arbitrary number of electric horizontal blinds 5 in parallel. Accordingly, even if the number of electric horizontal blinds 5 increases, the power consumption in the energy saving mode does not increase.
(4) The power controller 4 can be controlled by the central controller 3 and the operation switch 8.
(5) The power consumption in the energy saving mode can be reduced while the electric horizontal blind 5 is provided with the power supply circuit 28 for converting the commercial AC power supply 17 into the DC power supply.

  As shown in FIG. 7, the power supply interface 51 of the power supply controller 4 according to this embodiment converts the DC voltage supplied from the power supply circuit 16 into a predetermined voltage based on a control signal output from the microcomputer 15 and converts the DC voltage to a predetermined voltage. Output as power supply MD.

  The microcomputer power MD is supplied from the microcomputer power output terminal 52 of the power controller 4 to the microcomputer power input terminal 54 of the blind controller 7 via the wiring 53. Then, the microcomputer power MD supplied to the microcomputer power input terminal 54 is converted to a constant voltage by the power stabilization circuit 55 and supplied to the microcomputer 31.

  The microcomputer 15 of the power controller 4 supplies the microcomputer power MD from the power interface 51 to the blind controller 7 in the normal mode, and cuts off the supply of the microcomputer power MD from the power interface 51 in the energy saving mode. Further, the microcomputer power supply MD may be supplied also in the energy saving mode. The configuration of the power supply controller 4 other than the above is the same as that of the first embodiment.

  The non-contact relay 27 of the blind controller 7 supplies the commercial AC power supply 17 supplied to the connector 26 in the normal mode to the power supply circuit 56 based on a control signal from the microcomputer 31 and to the power supply circuit 56 in the energy saving mode. The supply of commercial AC power supply 17 is cut off. The non-contact relay 27 has a known function of starting supply of AC power to the power supply circuit 56 at a timing at which the AC power supply becomes a zero cross point, that is, when the AC power supply voltage becomes an intermediate voltage. The configuration of the blind controller 7 other than the above is the same as that of the first embodiment.

  FIG. 8 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.

In step 7, the supply of the microcomputer power supply MD from the power supply interface 51 is cut off under the control of the microcomputer 15. At this time, after the supply of the commercial AC power supply 17 to the power supply circuit 56 is interrupted by the blind controller 7 under the control of the microcomputer 31, the supply of the microcomputer power supply MD is interrupted.

In step 19, the supply of the microcomputer power MD from the power interface 51 is resumed under the control of the microcomputer 15.
FIG. 9 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). When 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 33 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 electric blind system configured as described above, the following operational effects can be obtained.
