[0047] The present disclosure aims to solve the problem of power failure and restart of the electrical control signal unit when changing its own electrical connection state by using a control method of an underwater splitter so as to quickly isolate the faulty equipment when the fault occurs in the underwater equipment without affecting the normal operation of other equipment on the line.

[0048] like Figure 1 As shown, the present disclosure proposes an underwater branch control circuit, characterized in that the circuit includes a main line, the main line includes a first relay group control circuit 1 and a first relay group 2;

[0049] One end of the first relay group control circuit 1 inputs an optical signal, and the other end of the first relay group control circuit 1 is connected to one end of the first relay group 2;

[0050] The circuit also includes a first branch line connected in parallel with the first relay group 2, the first branch line includes a second relay group control circuit 3 and a second relay group 4, one end of the first relay group 2 is connected to one end of the second relay group control circuit 3, the other end of the second relay group control circuit 3 is connected to one end of the second relay group 4, and the other end of the second relay group 4 is connected to the other end of the first relay group 2.

[0051] Specifically, the circuit further includes a second branch line connected in parallel with the second relay group 4 , and the second branch line includes a device 11 .

[0052] In this embodiment, the first relay group is composed of magnetic latching relays, which can control the electrical connection status of the main line according to demand; the relays of the second relay group are composed of non-magnetic latching relays, and the use of this type of relay can automatically isolate the fault when a branch device fails.
