Small intelligent digital display angular displacement sensor

Abstract

The invention provides a small intelligent digital display angular displacement sensor, which belongs to the technical field of sensors. The sensor comprises a shell; a first cavity and a second cavity are arranged in the shell; a gradienter is arranged in the first cavity; an auxiliary control board, a power supply board and a main control board are arranged in the second cavity, and a gyroscopechip, a temperature sensor chip and a vertical acceleration sensor chip are arranged on the auxiliary control board; a nixie tube is mounted on the power supply board; a CPU and a horizontal acceleration sensor chip are installed on the main control board; the sensor further comprises a first cover plate which is connected with the shell, and a first observation window is arranged on the first cover plate; the sensor further comprises a second cover plate which is connected with the shell, and a second observation window is arranged on the second cover plate; and the sensor further comprises at least one connector which is arranged on the shell and is connected with the power supply board and the main control board. And through the nixie tube on the power supply board, the current inclination angle value can be displayed in real time, so that maintenance personnel can correspondingly adjust a steel rail conveniently, and the safety of train running is improved.

Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to an angular displacement sensor, in particular to a small intelligent digital display angular displacement sensor. Background technique [0002] The tamping car widely used by my country's railway sector adjusts the height, direction and other parameters of the rail in the process of railway construction and maintenance, so as to improve the smoothness of the line and ensure the safe operation of the train. Among them, the height difference between the two rails (also known as the superelevation of the rails) is an important control amount during the tamping operation. [0003] Existing tamping vehicles use electronic pendulum angular displacement sensors to measure the superelevation of the rails, and this sensor uses a gravity pendulum to detect changes in the inclination angle, senses the swing angle of the pendulum through a potentiometer, and passes Damping oil to overcome the...
