Description

Technical Field

[0001] The utility model belongs to the technical field of shore-based power supply, and in particular relates to a shore-based power supply remote control system. Background Art

[0002] Shore-based power supplies are devices that provide electrical energy to ships and offshore facilities. When ships are moored at docks, ports, coasts, offshore platforms and other locations close to land, they often need to connect to shore power to meet the needs of ship life and business electricity. The advantage of shore-based power supplies is that they provide a stable power supply, preventing various problems caused by insufficient power on ships.

[0003] The shore-based power supply is equivalent to a high-voltage distribution box. For example, in the shore-based power supply system, the input end of the incoming high-voltage cabinet is connected to the 10kV mains electricity, the output end of the incoming high-voltage cabinet is connected to the input end of the isolation transformer through the high-voltage bus, the output end of the isolation transformer is connected to the input end of the outgoing cabinet, and the input end of the outgoing cabinet is connected to the input end of the dock power connection device; the dock power connection device is arranged at the ship berthing place, and the cable management device is arranged on one side of the dock power connection device. The output end of the dock power connection device is used to connect to the medium-voltage cabinet on the ship side through the cable management device. The medium-voltage cabinet on the ship side is connected to the input end of the connection transformer through the medium-voltage bus, and the output end of the connection transformer is connected to the ship-side microgrid through the grid-connected screen.

[0004] The existing shore-based power supply control device is connected to the shore-based power supply by wire, is often set near the shore-based power supply, and relies on manual operation. This control device is not only cumbersome to operate and inefficient, but also causes the shore-based power supply to be unusable once the control device fails. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] For details, please refer to Figure 1 , the shore-based power remote control system includes:

[0026] a first controller, the first controller being electrically connected to a plurality of sensors and a plurality of relays of a shore-based power source;

[0027] A second controller, the second controller is arranged in a mobile control box, a human-machine interaction interface is installed on the mobile control box, and the human-machine interaction interface is communicatively connected with the second controller;

[0028] The second controller and the first controller are electrically connected to their respective wireless communication chips.

[0029] The first controller and the second controller exchange data via the wireless communication chip, thereby realizing remote control of the shore-based power supply.

[0030] The first controller is installed in a housing of the shore-based power supply, the input port of the first controller is connected to a plurality of sensors, and the output end of the first controller is connected to a plurality of relays. The plurality of sensors include a temperature sensor, a voltage sensor, and a current sensor. Both the first controller and the second controller use CPLD.

[0031] The first controller receives data collected by the sensor and sends the data to the second controller through the wireless communication chip. The second controller outputs the received data to the human-computer interaction interface, and generates control instructions based on the control logic input by the human-computer interaction interface and the received data, and sends the control instructions to the first controller. The first controller executes the received control instructions on the corresponding relay.

[0032] In order to achieve global networking and improve communication quality, the first controller is electrically connected to the first network card, the second controller is electrically connected to the second network card, and both the first network card and the second network card are connected to the local area network. This method realizes the interconnection between the port's shore-based power supply and the control box.

[0033] In one embodiment, the input end of the first controller is electrically connected to the first positioning chip, and the input end of the second controller is electrically connected to the second positioning chip. Through the wireless communication chip, the first controller and the second controller can sense each other's position. Furthermore, the mobile control box includes a walking wheel and a drive motor, the walking wheel is transmission-connected to the drive motor, and the second controller is electrically connected to the control end of the drive motor. The mobile control box controls the walking wheel to move automatically based on the position of the target shore-based power supply and its own position. The specific navigation and walking control method is a prior art and will not be described in detail here.

[0034] The mobile control box is provided with a USB interface, through which the program file is input into the second controller.

[0035] A redundant power supply design is adopted. Specifically, a main power supply and a backup power supply are provided in the mobile control box. The main power supply and the backup power supply are connected to the main power supply line through a multi-way switch. A voltage sensor is provided at the output end of the main power supply, and the voltage sensor is electrically connected to the input end of the second controller. The output end of the second controller is electrically connected to the control end of the multi-way switch. The mobile control box is provided with a charging interface, and the charging interface is electrically connected to the main power supply and the backup power supply respectively.

[0036] Power supply redundancy is achieved by setting up a main power supply and a backup power supply. Both the main power supply and the backup power supply use batteries, and the capacity of the main power supply is much larger than that of the backup power supply. When the main power supply fails to supply power, the second controller obtains the abnormal output voltage of the main power supply through the voltage sensor, and immediately controls the multi-way switch to disconnect the main power supply and turn on the backup power supply to achieve power switching.

[0037] An alarm device is installed on the box body of the mobile control box, and the alarm device includes an LED lamp and a buzzer, and the alarm device is electrically connected to the second controller. The second controller processes the data received from the first controller, generates an alarm signal if there is abnormal data, and controls the alarm device to alarm to warn that the shore-based power supply state is abnormal.
