Magnetic resistance measurement sensing system and method thereof

Abstract

The invention relates to the field of machinery, in particular to a magnetic resistance measurement sensing system and a magnetic resistance measurement sensing method, through which the zero drift amount can be decreased during long-term use. The magnetic resistance measurement sensing system comprises a rigid lever, a pendulum magnet, two limit magnets, a Hall element and a computation system, wherein the rigid lever is provided with a fixed rotation shaft, a force application end and a measurement end; the force application end and the measurement end swing by taking the fixed rotation shaft as center; the pendulum magnet is connected with the measurement end of the rigid lever; the limit magnets are respectively arranged at two sides of the pendulum magnet and in a magnetic field range of the pendulum magnet; the limit magnets are opposite to the magnetic poles with same polarity of the pendulum magnet; when the rigid lever swings by taking the fixed rotation shaft as center under the action of external force, the pendulum magnet is close to the limit magnet at one side and far away from the limit magnet at the other side at the same time; the Hall element is arranged in the magnetic field range of the pendulum magnet and between the pendulum magnet and the limit magnets, and used for detecting the magnetic field change of the pendulum magnet and outputting signals; and the computation system is used for receiving the signals and computing the signals to obtain the magnitude of the external force stressed by the rigid lever.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a magnetic resistance force measuring sensor system and a method thereof. Background technique [0002] In the knitting, textile, chemical fiber, cable and other production industries, the constant tension of fibers and threads needs to be strictly controlled. Because the above industries need to use sensors that can monitor the force for a long time, continuous, real-time, and high precision in the production process, but currently The sensor has a large amount of zero drift during long-term use, which has limitations for the production industry that requires high precision and fast adjustment. Contents of the invention [0003] The invention provides a magnetic resistance force measuring sensor system and a method thereof, which can reduce zero point drift during long-term use. [0004] The invention provides a magnetic resistance force measuring sensor system, comprising: [0005] a...
