AUTOMATED SYSTEM FOR REGISTRATION AND DATA micrometeorological measurements in the atmospheric boundary layer

摘要

The complex acoustic anemometer and includes a gas analyzer measuring head which is mounted on or removal of the boom and connected by cables to a signal processing unit connected on the control signals and measurement signals through interface communication line to the control computer. In this block the signal processing is adapted to control the emitters and receivers of the anemometer, the synchronization frequency of the anemometer and the gas analyzer, the registration measurement signals, converting them to digital form, calculating the three components of wind speed and temperature, calculate concentrations of carbon dioxide and water vapor, calculation and storage medium measurements and statistical parameters comprises a microcontroller type PIG16C63A, connected via an analog-to-digital converter type AD7890-10 with bus cabling will measure ial heads and a digital adapter interface communication line to connect to the host computer. Interface communication link is formed with RS232 interface cable or wireless BlueTooth standard. 2 z.p.f. 10 yl.
