[0002] Multiple winches are generally installed at multiple workstations on offshore vessels (such as bow anchor winches and stern anchor winches). Currently, the operation of the winches at multiple workstations is generally controlled by the operator in the cab through a walkie-talkie to remotely control the corresponding operators at each workstation for coordinated operation. Each operator manually controls the winch next to the winch. This method is inefficient and has large operating errors. In addition, the winch stations are generally set up in the open air on the ship deck. The operators operate in the open air, which is greatly affected by the weather and poses a major safety hazard.

[0022] This embodiment provides a multi-station remote monitoring system for a ship towing winch, and its operation is briefly described as follows:

[0023] (1) Winch motion control: The control console issues motion instructions through the winch operating handle (single corresponding handle or linkage handle). The direction of the handle determines the direction of the winch, and the operating angle of the handle is proportional to the winch speed (the handle angle signal is calculated by the main CPU 15 and then outputs the control signal to the driver 312. The driver 312 has an opening feedback to form a closed-loop control). The control console 1PC touch screen selects whether to be single control (each winch is controlled independently) or linkage control (multiple winches are linked, only one control handle is needed to control the selected winch, and the movement direction of each linked winch is selected by the manual touch screen. For example, when moving the ship by winch, the winch at the bow reels in the cable, and the winch at the stern must release the cable. The speed of each winch is given by the rope length sensor and the tension sensor after comprehensive calculation by the main CPU 15 to maintain the pre-tension state and retraction and release force of each winch).

[0024] (2) Winch clutch control: The operator on the bridge monitors the position and movement of the clutch 321 through video monitoring, and controls the clutch 321 in real time as needed. At the same time, the clutch position feedback signal is sent back to the main CPU 15 to display the clutch status;

[0025] (3) Braking control. As needed, the operator on the driving console selects and controls the brake device of each winch through the operating knob of the control console 1. The angle signal of the knob is calculated by the main CPU 15 and output to the control solenoid valve. After the solenoid valve is actuated, the hydraulic oil drives the brake cylinder 332 to adjust the brake power arm. The cylinder stroke is proportional to the knob signal. The cylinder stroke feedback signal is compared with the input knob signal. The action stroke of the brake cylinder 332 is determined according to the difference. The positive or negative difference determines the action direction of the cylinder, thereby realizing closed-loop control of the braking device.

[0026] It can be seen that the multi-station remote monitoring system for ship towing winches provided in this embodiment can centrally control the winches of multiple stations from the driving console and monitor the status of the winches in real time, and centrally control the reversing, speed regulation, braking, and clutching of the winches; real-time detection includes video monitoring, speed monitoring, tension monitoring, stroke monitoring of the brake cylinder 332, etc. of the above actions, and can feedback control the above action process through the above monitoring data to achieve precise control and adjustment.
