The transformer 2 is connected with the external input power supply 2, so that the external input power supply 2 supplies power to the underwater control module 2 sequentially through the transformer 2, the power supply unit 2 and the umbilical cable.
The first power supply module and the communication module 1 are connected with the underwater electronic module 1 through a first umbilical cable to form a first branch; the second power supply module and the communication module 2 are connected with the underwater electronic module 2 through a second umbilical cable to form a second branch;

In one embodiment, the redundant control module is configured to:
when the first power supply module and/or the communication module 1 breaks down, the redundancy switching device 1 is controlled to perform switching operation, so that the underwater electronic module 1 is supplied with power and communicated through the second power supply module and the communication module 2.
In one embodiment, the redundant control module is configured to:
when the second power supply module and/or the communication module 2 breaks down, the redundant switching device 1 is controlled to perform switching operation, so that the underwater electronic module 2 is supplied with power and communicated through the first power supply module and the communication module 1.
In one embodiment, the type of failure of the first power supply module and the second power supply module comprises at least one of: the power supply current is increased instantly, and the power supply module trips;
the fault type of the communication module 1 and the fault type of the communication module 2 are communication loss.
In one embodiment, the redundant control module is configured to:
and when the first umbilical cable has a fault, controlling the redundant switching device 2 to perform switching operation so as to supply power and communicate with the underwater electronic module 1 through the second power supply module and the communication module 2.
In one embodiment, the redundant control module is configured to:

In one embodiment, the redundant switching device 1 and the redundant switching device 2 each comprise a first interlock switch and a second interlock switch connected in series.
The redundancy control process is described below in conjunction with fig. 2:
as shown in fig. 2, the EPU is powered and communicated to SEM a and SEM B by 4 SOMs (underwater Output modules), and each set of interlock switches is on and under water. When the device normally works, normally closed switches KM _ SOM2, KM _ SOM12, KM _ SOM23 and KM _ SOM14 are off, and switches KM _ SOM1, KM _ SOM22, KM _ SOM13 and KM _ SOM24 are also not on, so that each power supply independently supplies power. When a power failure occurs, there are roughly two cases:
1. if some SOM module on the water fails, such as the SCM A power output module fails, the normally closed switch KM _ SOM12 on the water is closed, and KM _ SOM22 is closed, the UPS2 can supply power to the SEM A through the branch.
2. If one umbilical of the underwater part fails, for example, the power supply umbilical for the SEM A fails, the underwater normally closed switch KM _ SOM14 is closed, and the KM _ SOM24 is closed, so that the current of the UPS2 can flow through the branch to supply power to the SEM A.
The EPU is configured with an underwater power carrier communication mode and forms a communication unit with the underwater. The communication unit comprises a modem and a filter and is integrated in the SOM module. The communication net ports of the two sets of main PLC are respectively connected to the two switches, and the two switches are connected with each other and then form a redundant ring network with the switch of the MCS (master control station), so that the reliability of system communication is improved. The gateway device of the EPU provides a communication link for the MCS by using a multi-broadband modulation and demodulation mode, and simultaneously configures a general TCP and RS485 interface to ensure the safe transmission of communication protocol data.
