Portable hand-operated box of ship dynamic positioning system

Abstract

The invention discloses a portable hand-operated box structure of a ship dynamic positioning system and an information acquisition and processing method. A hand-operated box is connected with a control console computer through an aviation plug, and a working power supply is acquired. Voltage conversion of the power supply is finished on an information acquisition plate, and power is supplied to an indication lamp on a hand-operated box panel, a PC 104 embedded industrial main board and the information acquisition plate. A single-chip microcomputer is used as a master control chip for acquiring simulation signals of a key and a hand-operated lever and controlling the indication lamp. Most elements are SMD elements, so that the size of a PCB is effectively reduced. A liquid crystal display on the hand-operated box dynamically displays information of ship motion states so that the running state can be conveniently monitored in real time, and control signals can be sent out at the corresponding moment. Input of transverse, longitudinal and yawing control instructions is achieved through the three-freedom-degree hand-operated lever. Due to the fact that the embedded structure is adopted in the portable hand-operated box and the signal acquisition plate and the PC 104 main board are fixed to the bottom of the hand-operated box, heat can be dissipated in time, and safe and reliable running of the system is guaranteed. The hand-operated box is simpler in structure, easier to operate and more convenient to install.

Description

technical field [0001] The invention relates to a special portable hand box and an information collection and processing method, in particular to a special portable hand box for a ship dynamic positioning system and an information collection and processing method, belonging to the field of marine engineering. Background technique [0002] With the development and utilization of offshore oil resources by human beings, as well as the continuous development of marine transportation and marine technology, ships and marine technology have risen rapidly. Because marine structures such as offshore platforms often need to be positioned at specific locations in the ocean, and here Operations at specific locations, such as marine surveys, oil well drilling, salvage and rescue, laying of submarine cables and pipelines, countering mines, etc. Due to the limitations of operating water depth, operating time and operating accuracy, the traditional anchoring method cannot meet the requireme...
