Ship horizontal attitude indicator

Abstract

The invention provides a ship horizontal attitude indicator, belonging to the field of ship electric equipment. The ship horizontal attitude indicator comprises a single chip microcomputer, a liquid crystal display, keys, a communication level conversion module, a gravity accelerometer transducer, a buzzer and a stable-voltage power source module. A signal wire on a pin of the single chip microcomputer is respectively connected with the liquid crystal display, the keys, the communication level conversion module, the gravity accelerometer transducer and the buzzer; and the stable-voltage power source module is connected with the single chip microcomputer, the liquid crystal display, the communication level conversion module, the gravity accelerometer transducer and the buzzer by leads, and supplies power to the components. The ship horizontal attitude indicator uses a digital integrated circuit sensor LSM303DLH to communicate with a chip through the single chip microcomputer and reads component information of three earth gravity accelerations of the internal gravity acceleration sensor in a horizontal direction and a vertical direction, so that a front-back pitch angle and a left-right inclination angle of a ship can be calculated and displayed by using an LCD (Liquid Crystal Display) liquid crystal. When the front-back pitch angle or the left-right inclination angle exceeds a certain range, the buzzer also can be used for alarming.

Description

technical field [0001] The invention relates to a ship level attitude instrument, mainly a ship level attitude instrument with digital display, and belongs to the field of ship electrical equipment. Background technique [0002] Due to the wind and waves on the sea surface and the ship's steering, the ship often tilts left and right or swings back and forth during navigation. When the tilt angle exceeds a certain range, there is a danger of capsizing. Real-time monitoring of the front and rear pitch angle and left and right tilt of the ship during navigation The angle has an important reminder function for the safe driving of the ship. At present, there is no ship level attitude indicator made of digital integrated circuit LSM303DLH in the ship. Contents of the invention [0003] The purpose of the present invention is to provide a ship level attitude instrument. [0004] The problem to be solved by the invention is that there is no horizontal attitude indicator made of ...
