The invention discloses a three-core four-axis crawler rapid natural gas pipeline robot control system. The system comprises a three-core controller composed of ARM, IRMCK203 and DPS which are in communication connection with one another. According to the above technical scheme, the system provided by the invention has the advantages that a brand new three-core control mode based on ARM+IRMCK203+DSP is independently developed, that is, the ARM is adopted as a processor core of the controller, the IRMCK203 is adopted for realizing servo control of a four-axis permanent magnet synchronous motor, and the DSP is adopted for realizing real-time processing of image acquisition digital signals and communicating with the ARM, so that the ARM can be set free from complex work, the real-time position of the four-axis three-phase permanent magnet synchronous motor can be acquired, a response to DSP interruption can be realized, as well as data communication and real-time signal storage can be realized.
