Sažetak
In order to explore and evaluate a number of different meteorological models and parameters, a quality high-speed data suitable for such purpose needs to be collected and processed. This paper presents a novel general-purpose meteorological data acquisition and logger system. It is implemented based on a Texas Instruments TivaC microcontroller, and has a possibility to scan up to 16 analogue and 4 digital sensors together. Analogue inputs have the voltage range from 0 to 5V, possibility of operation in differential and single-ended mode with a resolution up to 23 bits and sampling rate up to 1 kHz. Digital inputs are RS485 and RS232 compatible, with hardware handshaking and flow control. The system has a GPS receiver and a backup real-time clock built-in for the purpose of off-line measurement synchronization (data samples time-stamping) between several geographically distributed measurement locations. Analogue and digital data time stamping resolution is 1us. The measured data is stored in a removable, non- volatile random access memory (SD card) each hour for one month. Measurement set-up, control and monitoring is done over the mobile data network. This system is versatile and easily transportable. To verify its operation and specification, a number of measurement system performance tests and a comparison with another commercial data-acquisition system have been carried out and presented.
