Portable meteorological measuring instrument control system

Abstract

The invention discloses a portable meteorological measuring instrument control system, which comprises a frequency collection circuit, a wave detection feedback circuit and an operational amplification voltage stabilizing circuit, wherein the frequency collection circuit collects analog signal frequency when the portable meteorological measuring instrument works; the wave detection feedback circuit applies an operational amplifier AR1 and an operational amplifier AR2 to form a wave detection circuit to carry out signal wave detection on a frequency collection circuit output signal; meanwhile,an audion Q3, an audion Q5, a diode D6 and a diode D7 are used for forming a push-pull circuit; finally, through a buffer circuit formed by a resistor R12, a capacitor C4 and a diode 3, a signal is buffered to be input into the operational amplification voltage stabilizing circuit; an audion Q7 feeds back the signal to the same-phase input end of the operational amplifier AR2; finally, the operational amplification voltage stabilizing circuit applies an operational amplifier AR3 to carry out same-phase signal amplification; and meanwhile, an audion voltage stabilizing circuit formed by an audion Q8 and a voltage stabilizing pipe D10 is used for voltage stabilization to output. Data signal frequency can be converted into a compensation signal of the data signal of the portable meteorological measuring instrument, and meanwhile, the signal is automatically calibrated.

Description

Technical field [0001] The invention relates to the technical field of signal calibration, in particular to a control system of a portable meteorological measuring instrument. Background technique [0002] The main function of the portable weather station is to monitor the meteorological elements. It can monitor the wind speed, wind direction, rainfall, temperature, humidity, pressure and other meteorological elements in real time, and provide users with timely data support that can be referred to! However, in reality, in harsh environments, especially in storms, the data signal used by the control terminal of the portable weather measuring instrument to analyze the signal is often attenuated during the transmission process, resulting in the portable weather measuring instrument control terminal receiving The signal distortion seriously reduces the accuracy of the measurement results of the portable weather measuring instrument. [0003] Therefore, the present invention provides a...
