[0023] figure 1 The system configuration of the load control system of this embodiment is shown. The load control system of the present embodiment includes a plurality (four) of operation control terminals 10 (10A, 10B, 10C, and 10D), and a plurality (two) of operation terminals 20 (20A and 20B). Each operation control terminal 10 is connected to one or more loads L. Each operation terminal 20 is connected to a plurality of operation control terminals 10 via a two-wire signal line 30 . The load L is, for example, a light emitting load. Loads L ( L10 , L21 , L22 , L30 and L40 ) are connected to a commercial alternating current (AC) power source 50 via a power line 40 . The load L is not limited to light-emitting loads. The load L may be electrical equipment such as an air conditioner, a ventilator, and an electric curtain.

[0024] The operation control terminal 10A includes an operation switch S (S11). The operation control terminal 10A has a function (hereinafter referr...

[0105] Such as Figure 10 As shown, the load control system in this embodiment includes a transmission control device 100 , multiple operating terminals 102 and multiple control terminals 103 . Each operation terminal 102 and each control terminal 103 is connected to the transmission control device 100 via a two-wire signal line 105 . Each operation terminal 102 has switches S1, S2 and S3. Each control terminal 103 is connected to a lighting load (hereinafter referred to as "load") 104 and controls the load 104 connected thereto.

[0106] Each of the operation terminal 102 and the control terminal 103 has a specific address. The transmission control device 100 accesses the operation terminal 102 and the control terminal 103 by using the specific address.

[0107] The transmission control device 100 outputs to the signal line 105 with Figure 11A Transmission signal Vs in the format shown. That is, the transmission signal Vs includes a synchronization signal SY, mode data ...

Abstract

A load control system comprises a control device controlling a plurality of loads and an operating device operating a switch. The operating device is configured to an operation output control signal in response to the operating switch. The control device is configured to be individually controlled or commonly controlled according to the operation when receiving the control signal. In the individual control, the control device controls one of loads in response to the operating switch. In the common control, the control device controls a plurality of loads in a group correlated to the operating switch. The load control system comprises a storage device storing the control record in response to each load. The control record comprises a current state indicating the state of load after controlled by the control device and a previous state indicating the state of load before controlled by the control device. The operating device has a restoring switch and is configured to an operating output restoring signal in response to the restoring switch. The control device is configured to perform restoring control when receiving the restoring signal and varies the load state to the previous state stored in the storage device.

Description

technical field [0001] The present invention relates to load control systems, and more particularly to load control systems that control a load in response to manual operation of a switch. Background technique [0002] Document 1 (Japanese Patent Publication JP2003-37879A) discloses a load control system using time division multiplexing. [0003] The load control system disclosed in Document 1 enables a user to collectively control a plurality of loads. That is, the load control system provides collective control of the loads. However, when the user has erroneously performed common control on a plurality of loads, the user needs to control each load in order to change the current state of the load to the previous state of the load. Furthermore, the user needs to remember the previous state. Therefore, it is difficult to change the current state to the previous state. Contents of the invention [0004] In view of the above disadvantages, the present invention has been a...
