Self-powered wireless sensor node used for deviation detection of cold-rolled strip steel in loop area

Abstract

The invention provides a self-powered wireless sensor node which obtains kinetic energy of a loop trolley cylinder by utilizing friction drive, drives a generator to generate electric energy through a speed-up drive mechanism, reaches a requirement on a power output through rectification and voltage regulation, supplies power to a strip steel deviation detection sensor and sends strip steel position information to a corresponding data receiver in a wireless way. The scheme satisfies the requirement of the strip steel deviation wireless detection node on the power source under a moving condition, solves the problems of wiring difficulty and hard replacement of batteries, is convenient and flexible, is capable of carrying out on-line detection for the deviation phenomenon of the cold-rolled strip steel, judging the axial position of the strip steel rapidly and exactly and providing in-time and exact feedback control signals for a deviation correction system, and is good for avoiding occurrence of accidents and improving stability of the cold-rolled strip steel production system and safety of product production operation.

Description

technical field [0001] The invention relates to the field of system detection, and more specifically, relates to a self-powered wireless sensor node for detecting deviation of cold-rolled strip steel in a looper area. Background technique [0002] In the production of strip steel, problems in equipment, incoming materials, technology and operation will cause strip steel to deviate. Strip deviation will bring great harm to production, affect the quality of strip steel, and make the edges of steel coils uneven. When the deviation is serious, it will cause damage to the equipment, seriously affect the normal production, and cause major economic losses. [0003] Due to the limited capacity of the deviation correction system on the cold-rolled strip steel production line, the strip deviation phenomenon can be detected as early as possible when the strip deviation is small, and the alarm status can be transmitted to the deviation correction control system in time, which is very i...
