Abstract: Abstract: At present, the cantilever type roadheader control system has the problems of real-time data collection, inconvenient communication, and poor control of the control system. This paper designs a control system with DSP as the core. The control system uses DSP's abundant peripheral resources and superior data processing capabilities to complete the acquisition and calculation of the data of the roadheader's working conditions, real-time communication with peripheral devices, and realize the tunneling. The functions of precision cutting, automatic section control and remote monitoring of the machine cutting section provide technical support for the roadheader to adapt to automation and intelligent tunneling.
