High-sensitivity all-weather platinum wire resistance-type temperature pulsation instrument based on grey wolf compensation algorithm

Abstract

The invention discloses a high-sensitivity all-weather platinum wire resistance-type temperature pulsator based on a grey wolf compensation algorithm. The high-sensitivity all-weather platinum wire resistance-type temperature pulsator comprises an all-weather platinum wire probe, a solar irradiation intensity detection sensor ML8511, a signal amplification unit, an AD acquisition unit and a signal processing and communication interface unit. The all-weather platinum wire probe comprises a high-purity platinum wire with the diameter of 2mm, four small circuit boards and a BNC (bayonet nut connector), and the probe adopts a unique umbrella-shaped structure formed by the four small circuit boards and the BNC. The temperature pulsation meter has the advantages that the problem of circuit temperature increase caused by solar irradiation is eliminated by adopting the ML8511 sensor, the problem of platinum wire probe detection hysteresis is solved by fusing a grey wolf compensation algorithm to the signal amplification unit to construct a fourth-order active high-pass filter with optimal parameters, and the measurement precision and sensitivity of the temperature pulsation meter are improved; the umbrella-shaped design structure of the platinum wire probe solves the problem that the platinum wire probe is easy to damage when the temperature pulsation instrument works outdoors.

Description

technical field [0001] The invention relates to an experimental measuring instrument and a compensation method for atmospheric turbulence intensity, in particular to a high-sensitivity full-meteorological platinum wire resistance temperature pulsation instrument based on a gray wolf compensation algorithm. Background technique [0002] At present, with the rapid development of the optical field, the research of optical turbulence has gradually attracted attention. The platinum wire temperature pulsation instrument is an instrument that uses the principle of double-point thermometry to measure the structural constant of atmospheric refractive index to characterize the intensity of atmospheric turbulence. [0003] The traditional platinum wire temperature pulsation meter uses fine platinum wire as the temperature measurement material, which has the advantages of fast response and linear output. However, when the platinum wire temperature pulsation meter works in extreme outdoor...
