Platform compass control system based on multiple thick and thin current and relay control

Abstract

The invention discloses a platform compass control system based on multiple thick and thin current and relay control. A FPGA chip is adopted as a management chip of a system so as to provide multipledigital interfaces and multiple interfaces to connect with a voltage output type DA chip; a unilateral steady-state relay TQ12-12V is adopted, each current output circuit contains two relays controlled by the FPGA; the relays can control and switch the thickness and thin and direction of the switching current in an output circuit; a potentiometer adopts a digital potentiometer AD5206 to output sixpaths of different potential channels RP1 to RP6; an operational amplifier OP97 and the digital potentiometer AD5206 are adopted to construct two paths of current series negative feedback type voltage conversion current circuits; one path outputs the thick current and the other path outputs the thin current; and the relay TQ12-12V performs the control switching. Multiple output interfaces can beled out, the cost performance and the universality are strong, and the system has good practical promotional value.

Description

Technical field [0001] The invention relates to the field of platform compass control, in particular to a platform compass control system based on multi-channel thickness current and relay control. Background technique [0002] The platform compass is a sophisticated inertial navigation instrument that closely combines the traditional platform and compass. It can provide accurate heading and level reference information for the ship’s navigation, weaponry, command and control systems It has a wide range of applications. In the platform compass control system, the current output requirements are particularly complex and strict. The traditional current output system of the platform compass often cannot simultaneously output a large current with strong driving capability or a sufficiently precise fine current according to the actual situation. There are situations such as weak versatility and insufficient channels. [0003] More and more platform compasses hope that the current outpu...

In the platform compass control system, the current output requirements are particularly complex and strict. The traditional current output system of the platform compass often cannot output a large current with strong driving ability or a fine current with sufficient precision at the same time according to the actual situation.

There are situations such as poor versatility and insufficient channels
