Embodiment 1

[0045] see figure 1 , a marine propulsion gearbox connection and discharge control device, the marine propulsion gearbox is used to transmit the power output by the main engine system to the thruster propeller shaft, thereby driving the propeller propeller to rotate, and the propeller propeller A thruster propeller shaft brake device is installed on the shaft; the control device includes a control panel, a control unit, an on-site execution unit and a state detection module. The control panel is provided with a connection button, a discharge button, a control failure reset button, an emergency stop button, a gearbox connection / disconnection status indicator light, a gearbox control failure alarm indicator light and a buzzer. The on-site execution unit includes a solenoid valve for connecting and discharging the gearbox and a solenoid valve for discharging the gearbox. The state detection module includes a gearbox working pressure sensor, a gearbox connecting state sensor and ...

Embodiment 2

[0052] see figure 2 , a control method for a marine propulsion gearbox connection and discharge control device, comprising the following steps:

[0053] Step 1. Judging the connection / disconnection status of the gearbox:

[0054] A. Connection state: When the signal detection module detects that the gearbox generates a "gearbox connection state signal", it is judged that the gearbox is in the connection state. At this time, the gearbox connection / disconnection status indicator light on the control panel remains on. is always on.

[0055] B. Disconnection state: When the signal detection module does not detect that the gearbox generates a "gearbox connection status signal", it is judged that the gearbox is in the disconnection state. At this time, the gearbox connection / disconnection status indicator light on the control panel remains off.

[0056] Step 2. Issue the gear box connection / disconnection operation command: according to the gearbox is in the disconnected state or...

Abstract

A marine propulsion gearbox connection and discharge control device and a control method thereof, wherein the device comprises a control panel, a control unit, a field execution unit and a state detection module; the method includes: judging the connection / discharge state of the gearbox, Send out the gearbox connection / discharge operation command, determine the initial conditions of the gearbox connection / discharge, generate the gearbox connection / discharge control command, generate the gearbox connection / discharge solenoid valve power-on / loss control command, and the gearbox The discharge solenoid valve is energized / de-energized control command, and the gear box is connected / discharged. The service life of the electromagnetic switch valve for connecting, discharging and discharging of the gearbox is prolonged, so that the control of connecting and discharging of the gearbox is safer and more reliable; and the control process of connecting and discharging of the gear box is more intuitive.

Description

technical field [0001] The present invention relates to a control method for connection and discharge of a marine gearbox, more specifically to a control device for connection and discharge of a marine propulsion gearbox and a control method thereof, belonging to the technical field of marine propulsion control. Background technique [0002] In the field of marine propulsion, gearboxes are often used to connect the power source and the propulsion propeller shaft to transmit power to the propeller shaft. When it is necessary to connect the power source to the propeller shaft, the gearbox needs to be placed in a connected state; when it is necessary to cut off the connection between the power source and the propeller shaft, the gearbox needs to be placed in a disengaged state. The connection and discharge actions of the gearbox are realized by controlling the power-on and power-off of the connection solenoid valve and the discharge solenoid valve of the gearbox through a set o...
