Rudder angle suggestion system , including rudder angle feedback suggestion system of digital signal processing Taking STC series single chip microcomputer as the data processing unit , this paper focuses on the exploration and design of rudder angle feedback suggestion system from two corridor of system tackle and software The performance of rudder angle feedback suggestion system is compared and anatomized by bluffing boat navigation trial on tackle in the circle simulation platform The rudder angle feedback suggestion system handed by our company can eventually achieve high perfection and strong real- time performance .
Rudder angle index full view rudder angle index (hereinafter appertained to as index) is used to indicate the rudder angle position of the boat or marine . The index adopts the traditional moving coil movement to insure a veritably short response time. This index has three fairly large scales and visual areas , which insure that the indicated position of the rudder angle index can be read snappily and fluently from any angle within 250 ° and a distance of 5m . The index has night light function and long- life LED beacon, which can insure normal reading of data in a dark terrain . The index is leakproof , swab fog evidence and suitable for marine terrain .
In view of the low accuracy of the existing rudder angle feedback indication affected by the surrounding environment , a digital rudder angle feedback indication system and control method can be used Including rudder angle transmitter , junction box , rudder angle receiver , independent dimmer and indicator composed of receiver The transmitter collects the high-precision encoder signal and takes the compass feedback signal as the observation data of the transmitter . The chi square test method is used for robust control . Through data processing , the data information is transmitted to the fieldbus. The automatic steering instrument and other rudder angle indicators connected by the receiver complete the corresponding control and rudder angle indication Our rudder angle indication system has the advantages of simple operation , high precision and strong robustness . The rudder angle feedback indication effectively reduces the design cost .
