RVDT steering hand wheel control device and automatic detection method

Abstract

The invention discloses an RVDT steering hand wheel control device and an automatic detection method. The device is composed of four groups of RVDT signal processing circuits which have the same structure and have on-line automatic detection and BIT self-test functions, wherein each group of circuits consists of an RVDT signal analog switching circuit, an RVDT demodulation circuit, a rectifying, filtering and summing circuit, an amplifier, a main controller and an A / D sampling circuit, and can automatically detect disconnection and short circuit conditions of an RVDT lead terminal of an RVDT steering handwheel control device online in real time, moreover, a BIT self-testing circuit is arranged, a working state of an RVDT signal processing circuit is self-tested in an off-line mode, the detection result is reported to a main controller, and the device has advantages of being high in detection safety, reliability, comprehensiveness and practicability. The device is advantaged in that thedevice is mainly used for detecting an RVDT sensor which is an occasion with low action frequency, particularly in a steering signal, and is beneficial to greatly improving working reliability and safety of a multi-channel and multi-redundancy steering handwheel which is one of important naval vessel control components.

Description

technical field [0001] The invention relates to the technical field of steering handwheel control devices, and more specifically relates to an RVDT steering handwheel control device and an automatic detection method. Background technique [0002] RVDT sensors have been widely used in various industrial control and military control fields. They have the characteristics of high reliability and high safety, especially the characteristics of high sealing, non-contact, high sensitivity and high repeatability, and are suitable for use in the environment. Places with harsh conditions, high reliability, and high control precision requirements. The steering wheel module is one of the important components of ship manipulation, and its reliability and safety will directly affect the safe and reliable navigation of the ship. In order to improve the reliability of the operation of the submarine automatic steering equipment, the steering handwheel module of the submarine automatic steeri...
