Submarine cable warning device provided with state monitoring module

The utility model relates to a submarine cable warning device, and specifically discloses the submarine cable warning device provided with a state monitoring module. Submarine electronic warning boards are mostly installed at remote locations, so the daily management and maintenance are complex and difficult to carry out. The warning device comprises a warning board, an LED lamp arranged on the warning board, a driving circuit and a power supply module. The power supply module is connected to the driving circuit, and the driving circuit is connected to the LED lamp. The power supply module is connected to the LED lamp through the driving circuit. The warning device is characterized in that the warning device also comprises an electric information acquisition module, a communication module, and a processor connected to the electric information acquisition module and the communication module; the electric information acquisition module comprises a switch state acquisition circuit, a flash period acquisition circuit, a charging voltage acquisition circuit, a battery voltage acquisition circuit, an illumination intensity acquisition circuit and an LED lamp working current acquisition circuit which are arranged on a PCB. By employing the technical scheme provided by the utility model, manual inspection is simplified and replaced by remote measurement, so that working intensity is reduced, and the working security is improved.
