establishing communication connection with an internal control device of a shore-based equipment layer, and sending a control instruction to the internal control device;
controlling the internal control device to establish communication connection with the shore power box through various protocols; sending an instruction to a shore power box to start power supply;
and closing the power supply switch and supplying power through a cable connected with the ship, so that the ship enters a power supply state.
8. The method of claim 7, further comprising:
receiving order placing information generated by scanning two-dimensional code information of the port of the shore power box through terminal equipment by a user;
judging whether the port state of the shore power box is on line or not;
if the port of the shore power box is on line, continuously judging whether the port of the shore power box is in an idle state;
if the port of the shore power box is in an idle state, continuously judging whether a cable between the port and the ship is connected or not;
if the port of the shore power box is in a connection state, sending a power supply instruction to the station-level system;
generating a new shore power order, synchronizing the new shore power order to the station-level system, and simultaneously carrying out metering and charging on the shore power platform and the station-level system;
and receiving a power supply starting metering indicating value sent by the station level system to the shore power platform system by the shore power box.
9. The method of claim 7, further comprising:
receiving remote signaling data, remote measuring data and metering data of a shore power box in the shore-based equipment layer, which are sent by the station-level system, at intervals of a preset time period;
and counting the electric quantity, the electric charge and the electricity utilization condition of the shore power box according to the remote signaling data, the remote measuring data and the metering data.
10. The method of claim 7, further comprising:
receiving a power failure instruction of a user, and issuing the power failure instruction to the station-level system;
and generating a corresponding transaction record, uploading the transaction record to an order center, and informing a user of online payment.
