An intelligent weather sensor

Abstract

An intelligent meteorological sensor comprises a sensing unit, a signal conversion unit, an embedded microprocessor, a communication interface unit and a power unit, wherein the embedded microprocessor performs data processing on a digital signal output by the signal conversion unit through a relevant intelligent algorithm, receives parameter settings of an upper computer, as well as performs self-inspection and self-diagnosis of the sensor; the relevant intelligent algorithm is as follows: after interface initialization of the embedded microprocessor, judging whether the minimum sampling time of the meteorological sensor is reached, if so, sampling and processing sampled data, otherwise, judging whether the meteorological element output time stated in a communication protocol is reached, if so, outputting processed data in the embedded microprocessor, otherwise, returning and further judging whether the sampling output time is reached, if so, outputting the processed data in the embedded microprocessor, otherwise, returning and further judging whether the sampling time is reached or not. The intelligent meteorological sensor directly outputs meteorological parameters required to be measured.

Description

technical field [0001] The invention relates to the design of meteorological sensors, especially the intelligent design of various meteorological sensors. Background technique [0002] Meteorological sensors are important components for measuring meteorological elements. Traditional meteorological sensors are composed of figure 1 As shown, it is mainly composed of sensitive elements and signal conversion units, etc., and the output is electrical parameters such as resistance, voltage or pulse signals, rather than meteorological parameters such as temperature, humidity, air pressure, wind direction, and wind speed that need to be measured. To convert electrical parameters into meteorological parameters, another data collector is required to complete signal conditioning, linearization processing, calibration conversion, data quality control, etc., because the compensation parameters and calibration coefficients of various sensors are solidified in the data collector , and the...
