| Abstract: | A meteorological parameter and atmospheric turbulence measurement system was described in this paper. A/D conversion was done by VFC (Voltage Frequency Changer). The system has been implemented at a 27 m tower in Gaomeigu Yunnan Astronomical Observatory, that includes three levels fast-response temperature sensors and two slow-response temperature sensors, a humidity sensor, a pressure sensor, a propeller-vane anemometer, Computer selects input channels and pulse signal is counted by 5253 counter, so the system cost is low and the measuring precision of long distance sampling signal can be ensured. |
