The first embodiment of the present invention shows a sequential control device for sequentially activating the control target device one by one, and sequentially deactivated one by one.

This sequential control device 2 is arranged between the controller 1 and the control target device 3 as shown in FIG. The control target device 3 is sequentially activated and deactivated in accordance with the control signal of the controller 1. Here, the control target device 3 may be a variety of electrical and electronic devices such as light emitting means such as LED, speakers.

The sequential control device 1 includes a plurality of input / output terminals for transmitting and receiving signals with the controller 1, the control target device 3, and the sequential control device 1 at the front and rear ends.

The input / output terminal receives a drive signal input terminal 10 to which a drive signal Sig_Act for driving the control target device 3 is input, and a non-drive signal Sig_Nor for non-drive to the control target device 3. The non-drive signal input terminal 20, the activation signal input terminal 30 to which the activation signal Act_in for sequential activation control is input from the controller 1, and the clear signal Clr_in to deactivate the control target device 3.

The control signal is output to the switch 81 and the clear signal is controlled to be output through the clear output terminal.

The control operation of the logic unit 83 will be described with reference to the flowchart of FIG. 3 as follows.

In FIG. 3, Q0 is a 1-bit memory inside the logic unit 83. When the selection control signal sel is 0, the non-drive signal Sig_nor is transmitted to the driving signal output terminal 50 Sig_out, and the selection control signal sel is If 1, the driving signal Sig_act is transmitted to the driving signal output terminal 50 (Sig_out).

Referring to FIG. 5, when the power is first turned on, the internal memory Q0 and the selection control signal sel become zero. Since Q0 is 0 in the first activation signal pulse, Q0 is set to 1 and the selection control signal sel is set to 1 to transfer the activation signal pulse to the drive signal output terminal 50. Then, in the activation signal pulse, the selection control signal sel is set to 0 to transmit the non-driven signal Sig_nor to the drive signal output terminal 50, and the activation signal to the activation signal output terminal 60 to provide the next sequential control device. Activate it. The clear signal can then be used to initialize Q0 to zero, starting with the first sequential control.
