3 Terms and definitions

GB/T 35221 and defined by the following terms and definitions apply to this document. 3.1 Data Collector datalogger Able to automatically collect power from the sensor signal, and automatically collect data analysis and processing of the measurement system. Note, often referred to as the collector. Often, the collector has microprocessors, system software, and algorithm-specific software that is at the heart of automated weather stations. 3.2 Sampling instantaneous value samplinginstantaneousvalue A single measurement of the meteorological element at some point obtained during the sampling process. Note. Often referred to as the sample value. 3.3 Instantaneous meteorological instantaneousvalue Meteorological element instantaneous value Meteorological element in a certain observation period [sampling instantaneous value] average or total. Notes 1. For most meteorological elements, the mean value of the instantaneous value of the sample within one minute. However, there are exceptions, such as the wind has an average of 2min and 10min. Right Meteorological elements, refers to the calculation of the total number of sensor output pulses, such as rainfall. It should be noted that do not need a longer period of time with the application areas Within the average or total confused. Note 2. The instantaneous meteorological value of each minute for each meteorological element can be calculated, or the average of the instantaneous values of the samples for the current minute, or the number of minutes before Moving average of sampled instantaneous values within.

4 data acquisition and processing

4.1 Data Acquisition 4.1.1 The sensor should be capable of scanning at a predetermined sampling rate (see Table 1) and converting the resulting electrical signal into a microprocessor readable signal Number, get meteorological elements of the measured value sequence. 4.1.2 It should be able to convert the measured values of meteorological elements so that the electrical signals output by the sensors are converted into meteorological quantities and the instantaneous values of the samples are obtained. ......
