Attitude control system and method based on wireless three-dimensional gyroscope technology for scraper conveyer

Abstract

The invention discloses an attitude control system and a method based on a wireless three-dimensional gyroscope technology for a scraper conveyer. The system comprises a wireless three-dimensional gyroscope, hydraulic brackets, a bracket controller and a crossheading monitoring host, wherein the wireless three-dimensional gyroscope is arranged on a sliding chute of the scraper conveyer, and is used for detecting the running attitude of the scraper conveyer; a plurality of hydraulic brackets are connected to one side of the scraper conveyer in sequence; the movement of the scraper conveyer is realized under the pushing actions or pulling actions of the hydraulic brackets; the bracket controller is arranged on the hydraulic brackets, and is used for controlling the pushing or pulling actions of the hydraulic brackets; the crossheading monitoring host is arranged in a crossheading, and is used for concentrically monitoring and controlling the scraper conveyer, the bracket controller and hydraulic brackets; the wireless three-dimensional gyroscope is only communicated with the bracket controller in a wireless way; and the crossheading monitoring host and the bracket controller constitute a communication network system on a work surface through the bracket controller for performing data communication, so that attitude monitoring of the scraper conveyer is realized.

Description

technical field [0001] The invention relates to a scraper conveyor attitude control system and a control method, which are composed of a wireless three-dimensional gyroscope, a bracket controller, a monitoring host, etc., and are used for the attitude control of the scraper conveyor in a fully mechanized coal mining face. Background technique [0002] The fully mechanized mining face is composed of coal mining machine, scraper conveyor and hydraulic support. The scraper conveyor is composed of a section of chute connected. The child is fixedly connected, and the hydraulic support is used to push the telescopic action of the jack to push and implement the movement of the scraper conveyor. Therefore, the attitude of the scraper conveyor is completely controlled by the push and pull actions of the hydraulic support. Since the scraper conveyor is formed by connecting chutes, the movable gap between the chutes is limited, and the angle between the chutes cannot be too large. If ...

AI Technical Summary

Problems solved by technology

At present, the working face of the hydraulic support manual system is all manually pushed or pulled to control the attitude of the scraper conveyor. The electro-hydraulic control system of the hydraulic support uses a stroke sensor to control the movement of the hydraulic support. The connection hole of the hydraulic support is U-shaped, and there is a large gap between it and the connection head of the push rod of the hydraulic support. During the moving process of the hydraulic support, the stroke will produce a large error accumulation, resulting in uneven movement of the scraper conveyor. , it also needs to be adjusted manually, which reduces the production efficiency
