Automatic floating dock heaving control system

Abstract

The invention relates to an automatic floating dock heaving control system which is characterized in that the system comprises a pressure level telemetry system, a water pump valve remote control system and a display alarm control system, the pressure level telemetry system and the water pump valve remote control system are connected with the display alarm control system, and an industrial controller is connected with an operation terminal and a backup operation terminal through routers. The automatic floating dock heaving control system of the invention has the following beneficial effects: the automatic floating dock heaving control system can automatically judge and switch the heaving mode according to a depth value set by an operator in an operation station, automatically cause corresponding water pumps and valves to perform load heaving operation, and automatically stop operation when the set depth value reaches without manual interference; and the system has the functions of automatic heaving mode switching, manual and automatic switching, intelligent floating state regulation, overrun alarm, fault alarm and the like, and has higher safety and reliability.

Description

technical field [0001] The invention belongs to the intelligent control of the ups and downs of a floating dock, in particular to an automatic control system for the heave of a floating dock. Background technique [0002] Most of the traditional dock heave control is done manually. The staff first manually judges the floating state and calculates the stowage according to the liquid level of each ballast tank and the hexagonal draft of the bow, middle and stern on both sides of the floating dock, and then opens the heave control. The water pumps and valves of the system make each ballast tank water in or out, so that the working conditions of the dock heave meet the specified requirements. In this water transfer process, it is necessary to adjust the opening of the valves of each cabin according to the real-time tilt state of the dock to adjust the rate of inflow and drainage of each cabin, so that the dock can heave smoothly. The disadvantages of the manual control method a...

Problems solved by technology

[0003] Domestic research on the automatic control of dock load heave mainly stays at the theoretical level, and there are some technical applications, but the overall degree of automation is not high enough, the functions are not perfect, and the safety and reliability are not high enough.
