In general, a name flag is one of the navigation markers which mark the course of the ship or mark the maritime safety information. It is a device that guides the course of the ship by lighting at night.

In addition, since the light emitting unit is installed at a remote place where the power is not always supplied, the power supply is not smoothly provided, so that a separate power source .

In this case, when the loader and the plurality of loads are directly connected to each other so that the loads are operated, since the power is not applied to the plurality of loads connected to the lifter, when the loader fails, I can not help but stop.

Therefore, the power facility has to be operated independently from the lighthouse and the roads,

In response to this necessity, a system has been developed in which a charge / discharge regulator is separately installed inside the route marking facility, and a plurality of rods and lamps are connected to each other to operate the respective rods.

For the reference, the charge / discharge regulator should be designed to be 10V, 20V, 30V and supply it according to the power consumption capacity of the road marking facility. In case of replacement or change due to failure of each rod, Considering the performance, it is necessary to control the charge / discharge regulator.

However, such a charge / discharge regulator is installed in a sealed state inside the route marking facility and is safely protected,

In order to diagnose whether or not the maintenance personnel is abnormal, it is difficult to diagnose the abnormality only after moving to the maritime labeling facility and disassembling the enclosed power supply facility,

In particular, there is a problem that the electronic equipment connected to the charge / discharge regulator is broken due to the electromagnetic wave or the back electromotive force generated due to the malfunction of the charge / discharge regulator. Therefore, it is necessary to check periodically.
