Description

A coach system and operation training method for QDT comprehensive driving control operation training

Technical Field

The present invention relates to the technical field of ship simulators, and in particular to a trainer system and an operation training method for QDT comprehensive driving and control operation training.

Background Art

Ship simulator technology is an effective technical means to assist ship driver training. In the 1980s, foreign countries carried out research on ship driving simulators. The latest navigation and maneuvering simulator developed by British Merchant Shipping Co., Ltd. can provide simulated operation training for captains and other shipboard personnel of ships and fishing boats; the full-function maneuvering simulator of ShipAnalytic Company in the United States can provide basic communication and maneuvering skills, ship supply, rescue operations and naval tactics training; the North Star full-mission ship maneuvering simulator of Konsberg Maritime Company in Norway is the most complex and widely used navigation simulator to date. Domestic research on ship simulators started late. Shanghai Maritime University began to study ship maneuvering simulators in 1989 and successfully developed the SMU-VI large ship comprehensive maneuvering simulator system equipped with the same basic equipment as the real ship, which can realize basic maneuvering training; Dalian Maritime University invented a high-quality navigation simulator, which consists of three parts: ship motion model, simulated control console and visual system. The simulator has passed the highest level of navigation simulator performance index certification of the Norwegian Classification Society.

QDT (air cushion craft) is an amphibious ship that uses a high-pressure air cushion between the bottom of the ship and the sea surface to detach the hull from the sea surface to reduce its own resistance during navigation, so that it can sail at high speed on the sea and land. It has become a new means of landing transportation. Because QDT may encounter dangerous situations such as bowing its head, mechanical failure, and damaged aprons when sailing at high speed on the sea, it is necessary to complete driving operations such as climbing, crossing obstacles, and crossing trenches when landing on the shore, which requires the driver to master skilled driving control techniques. If real T training is used, not only will the training cost be very high, but it will also bring certain dangers due to improper operation. Therefore, it is very necessary to use a QDT simulator to complete driving control training. Comprehensive driving control training can greatly shorten the real T training cycle while ensuring safety.
