Air cushion track leveling system based on single chip microcomputer control

Abstract

The invention provides an air cushion track leveling system based on single chip microcomputer control. The air cushion track leveling system comprises an air cushion track, an air supplying pipe, anair pump, supporting feet, a telescopic adjusting device, measuring glasses, photoelectric sensors, liquid communicating vessels, a controller, a liquid crystal display screen, a switch and a tilt angle sensor; the three measuring glasses or the three photoelectric sensors are adopted and used in a paired mode, each measuring glass or each photoelectric sensor is fixed to one side of the corresponding supporting foot, wherein the lower parts of the measuring glasses are connected through the liquid communicating vessels, and the photoelectric sensors are connected with the controller through signal lines; and the controller is fixed to the lower part of the air cushion track, and the tilt angle sensor is mounted on one side of the controller. According to the air cushion track leveling system, by arranging the telescopic adjusting device, the measuring glasses, the photoelectric sensors, the liquid communicating vessels, the controller and the tilt angle sensor, the structure is simple, the defect that the air cushion track is not prone to being leveled is made up, the demands of experimental data results are met, and the error of experiments due to the uneven air cushion track isavoided.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, in particular to an air cushion guide rail leveling system controlled by a single-chip microcomputer. Background technique [0002] As we all know, the air-cushion rail experimental instrument used in the physics experiment teaching of colleges, technical secondary schools and high schools at present, a key step in the experiment is "leveling". By adjusting the anchor bolts of the air-cushion rail, the air-cushion rail is level. One step directly determines the accuracy of the subsequent experimental results. The general leveling methods are divided into "static leveling" and "dynamic leveling". "Static leveling" is to turn on the air source, put the slider on the guide rail, adjust the vertical horizontal double-leg screw and the horizontal horizontal single-leg screw of the guide rail until the slider can stay still or move extremely slowly at any position on the guide rail.
