Hardware-in-loop test simulator for dynamic positioning control system and operating method of test simulator

Abstract

The invention discloses a hardware-in-loop test simulator for a dynamic positioning control system and an operating method of the test simulator. The simulator comprises a real-time I / O (Input / Output) interface and a simulation module of the dynamic positioning control system, wherein the simulation module of the dynamic positioning control system comprises a power management system module, a propelling device module, a ship or offshore floating platform motion module, a position reference system module, a fault simulation module, a marine environment simulation module and a human-machine interaction interface; the simulation module of the dynamic positioning control system conducts real-time data exchange with a to-be-tested dynamic positioning control system through the real-time I / O interface, receives expected command signals of a propelling system transmitted by the to-be-tested dynamic positioning control system, and sends simulated output signals of the dynamic positioning control system to the to-be-tested dynamic positioning control system. The hardware-in-loop test simulator can avoid the risks of actual ship tests, and saves the test cost. The hardware-in-loop test simulator comprises the real-time I / O interface to be directly connected with the to-be-tested dynamic positioning control system, so as to be used conveniently.
