Automatic Data Acquisition

This paper is devoted to the design and simulation of an automatic data acquisition system of solar module characteristics. The system is essentially composed of three parts. The first part is devoted to the acquisition of the electrical parameters of the solar module (Current, Voltage and Power) in automatic ways using an automatic variable load. The second part is focused on devices which measure the ambient temperature and solar irradiation. In the last part, we study the design of an acquisition interface and a database for data saving. The results of simulations validate the correct operation of the measuring bench.

Automatic Data Acquisition

The Central Research Institute of Electric Power Industry conducted research to develop a long-term monitoring technology to clarify pore water pressure and water chemistry in drilled boreholes. An automatic data acquisition system for the long-term monitoring was also developed. The automatic data acquisition system has an independent electric power supply and data communication system. The electric power is supplied from solar and wind power. The data communication is secured through a satellite or 3G/4G line. A very low power consumption system can be readily installed by creating personal area networks between measuring devices using Zigbee digital radio. A demonstration of the system was conducted under harsh natural conditions for 18 months. It was confirmed that the system has sufficient reliability for actual operation.
