A Data Acquisition System for Methane Drainage Based on ARM and FPGA

For the urgent need of methane drainage in coalmine safety field, a data acquisition system was proposed which is based on ARM and FPGA. The complex data collection and data processing were carried out for the environmental parameters, gas parameters and equipment parameters. The complex tasks were scheduled effectively based on embedded operation system, and the multi-channel acquisition was designed reconfigurable based on large-scale programmable logic device. The work improves the accuracy and real-time ability of the gas flow acquisition, and provides a technical support for methane drainage.
