Embodiment Construction

[0046]A digital rudder angle feedback indication control method is characterized in that the steps are:

[0047] 1) Calibration: Verify the rudder angle transmitter (105), turn on the switch, turn the steering gear to the left setting degree, zero degree, and right setting degree in turn, and press the verification button at the corresponding angle to complete the verification. Make the step size of the high-precision encoder linearly correspond to the rotational position of the steering gear.

[0048] 2) Signal acquisition: the rudder angle transmitter (105) collects rudder blade angle data and compass feedback data of the steering gear through the encoder data acquisition module.

[0049] 3) Signal processing: carry out weighted average processing on the rudder blade angle data, observe by collecting compass feedback data at the same time, normalize the measurement information, and perform robust control through the chi-square detection method; if the noise obeys the Gaussia...

Abstract

The invention discloses a digital rudder angle feedback indication system and a control method. Aiming at the problem that the existing rudder angle feedback indication is low in precision due to theinfluence of the surrounding environment, the invention provides a digital rudder angle feedback indication system and a control method. The digital rudder angle feedback indication system comprises arudder angle transmitter, a junction box, a rudder angle receiver, an independent dimmer and an indicator body composed of receivers. The transmitter collects signals of a high-precision encoder, meanwhile, compass feedback signals are taken as observation data of the transmitter, robust control is conducted through a chi-square test method, and through data processing, data information is transmitted to a field bus, an automatic steering instrument and other rudder angle indicators formed by connecting receivers to complete corresponding control and rudder angle indication. Rudder angle feedback indication which is easy to operate, high in precision and high in robustness is finally achieved, and the design cost is effectively reduced.

Description

technical field [0001] The invention relates to a marine rudder angle feedback indicating system, in particular to a digital rudder angle feedback indicating system and a control method. Background technique [0002] With the needs of my country's marine development, the overall product design and manufacturing of marine engineering equipment is developing in the direction of digitization, networking and intelligence. Among them, the rudder angle feedback indication system is an indispensable navigation equipment on modern ships. Its main function is to output the current ship's rudder angle position automatically and with high precision, and transmit the data information to the automatic steering instrument and other rudder angle indicating equipment. To ensure the ship's safe sailing and precise navigation in harsh environments. Therefore, the performance of the rudder angle feedback indicating system will be directly related to the safety of the ship's navigation, and di...
