Research on Mine Water Quality Monitoring System based on SOPC

摘要

As for the severe situation of mine water hazard in our country, it is extremely urgent to find ways of preventing and managing mine water hazard. This paper proposes a design of system which adopts fluorescence detecting technology and uses SOPC as the core control module, it can quickly detect the changes of mine water hazard source. This system collects signal of fluorescence produced in laser irradiation of water, and turns it into electric signal which is later be collected by ADC and then sends the digital data into FPGA for storing and managing. SOPC is designed in Quartus II software, and program code is designed in Nios II software, which will finally be downloaded into FPGA. A test of data collecting, handling and storing is carried out in the lab to verify the feasibility of the system. The results show that the system can efficiently detect the changes of mine water hazard source.
