Abstract
The paper proposed a design scheme of control system of roadheader based on DSP and CPLD, introduced overall design and designs of CPLD data collection module and CPLD logic control module of the system. The system uses CPLD to realize data collection, which saves 12 μs of waiting time of DSP at each AD sampling channel and saves total 300 μs in each AD sampling period of 25 channels and uses CPLD instead of standard logic devices to realize logic functions, which simplifies design of hardware circuit and improves integration of the system. The application showed that the system can meet requirements of normal production of roadheader with good real-time performance and high reliability.关键词
