Abstract

PURPOSE:To recognize a melted fuse and a broken communication line by connecting a control circuit to a communication line not through a fuse and arranging a terminator connecting to the communication line when the control circuit is active to a post-stage after the fuse, that is, to the side of a terminal equipment. CONSTITUTION:Fuses F1, F2 connected to a line between a control circuit CONT and break contacts rl2, rl2 to connect a termination circuit TER to the communication line when the fuses F1, F2 are normal, that is, not melted. Then the test to identify the presence of the termination circuit TER is executed via the communication line and when the connection of the termination circuit TER is identified, the fuses F1, F2 are discriminated normal. When the connection of the termination circuit TER is not detected, since the communication line is discriminated normal, at least either of the fuses F1, F2 is discriminated to be melted out. Thus, the broken communication line and the melted fuse are identified.

う欠点を有していた。Due to the above configuration, the conventional disconnection control device has the fuse Fl.
, If F2 is disconnected for some reason, the disconnection control device will not operate even if a disconnection control signal is sent from the communication line, and the communication line will not work even if a test is performed from the communication line. Since continuity cannot be obtained between the two constituent wires, it has the disadvantage that it is not possible to distinguish between a failure in the communication line and a failure in the fuse.

本発明の目的は、ヒユーズ断と通信回線断との識別が可
能な切分制御装置を提供することにある。An object of the present invention is to provide a disconnection control device that can distinguish between a fuse break and a communication line break.

た。[Means for Solving the Problems] In order to achieve the above object, in the present invention, a control circuit is connected between two lines constituting a communication line, and a control circuit is provided from the upstream side of the two lines. When the control circuit operates in response to a signal, the cut-off contact of the control circuit connected in series to the two lines on the downstream side switches, and the terminal device connected ahead of it is switched. In a disconnection control device configured to disconnect from the communication line, a fuse is connected to the line between the control circuit and the disconnection contact, and the disconnection contact of the control circuit is switched to disconnect the terminal device from the communication line. At this time, a terminating device is connected to the communication line via the disconnection contact instead of the terminal device.
