Description

Technical Field

[0001] The utility model relates to the technical field of ship control systems, in particular to a main engine remote control system. Background Art

[0002] The main engine of a ship mainly refers to the engine used to drive the ship, while the main engine remote control refers to the remote control of the main engine at the bridge. In this way of operation, the main engine is not operated directly by the actuator itself, but the control signal is sent by the bridge controller to communicate with the engine room controller, so that the engine room controller controls the actuator to complete the operation of the main engine. It realizes the unmanned cabin, improves the working conditions of the main engine management personnel, improves the ship's maneuverability, and can also improve the safety of ship navigation, as well as the reliability and economy of the main engine operation.

The cab controller is respectively connected to the display, the alarm unit, the machine-side controller, and is connected to the operating handle through the A / D conversion module.

[0004] The above-mentioned host remote control system does not have a corresponding emergency response system for the failure of the machine-side controller.

[0005] Once the machine-side control box fails (such as serious aging of the line and equipment, improper daily maintenance operations, fuse burnout, etc.), the main engine equipment will not operate normally, reducing the quality of the main engine operation; since the source of the fault cannot be identified and eliminated in time, the fault will spread or the system will be paralyzed, resulting in the automated ship having to be operated manually. All these affect the navigation safety of the ship and increase the difficulty of maintenance management. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0019] The host remote control system is described in detail below in conjunction with the accompanying drawings and embodiments. Example

[0020] A host remote control system includes: a cab remote control unit 10; a main cabin control box 20, electrically connected to the cab remote control unit 10; a spare cabin control box 30, electrically connected to the cab remote control unit 10; an actuator 40, electrically connected to the main cabin control box 20 and the spare cabin control box 30 respectively; a switching circuit 50, the switching circuit 50 includes: a detection circuit 51, electrically connected to the main cabin control box 20 and the spare cabin control box 30 respectively, a first controller 52, electrically connected to the detection circuit 51, and electrically connected to the main cabin control box 20, for controlling the connection of the main cabin control box 20; a second controller 53, electrically connected to the detection circuit 51, and electrically connected to the spare cabin control box 30, for controlling the connection of the spare cabin control box 30.

[0021] During operation, when the detection circuit 51 detects that the main cabin control box 20 fails and cannot be used, the switching circuit 50 will control the first controller 52 to cut off the connection of the first controller 52, and the second controller 53 starts to control the connection of the standby cabin control box 30, thereby completing the switching of the cabin control box, ensuring the normal operation of the host equipment, and improving the quality of the host operation.

[0022] The detection circuit 51 mainly detects the current of the main cabin control box 20 through a current or temperature sensor, and determines whether a fault occurs in the main cabin control box 20 based on whether the temperature is within a normal threshold.

[0023] The detection circuit 51 can also determine whether the main engine room control box 20 is faulty by detecting the main engine speed of the actuator 40 to determine whether the main engine is operating normally.

[0024] The main engine speed is mainly detected by a magnetic element and a Hall sensor or a magnetic sensitive sensor installed on the main engine shaft to detect the rotation signal of the main engine. Example

[0028] When the detection circuit 51 detects that a fault has occurred in the main cabin control box 20, a first pulse signal will be sent out through the first pulse switch 511. After receiving the first pulse signal, the main controller 521 of the first controller 52 controls the main contact switch 522 to be disconnected, thereby stopping the use of the main cabin control box 20; and a second pulse signal will be sent out through the second pulse switch 512. After receiving the second pulse signal, the standby controller 531 of the second controller 53 controls the standby contact switch 532 to be closed, so as to start the use of the standby cabin control box 30.

[0029] During actual use, the cab remote control unit 10 includes a cab PLC, the main cabin control box 20 includes a main cabin PLC, the standby cabin control box 30 includes a standby cabin PLC, the cab PLC and the main cabin PLC are connected via a serial communication interface; the cab PLC and the standby cabin PLC are connected via a serial communication interface.
