Intelligent digital controller of flexible material cutting robot and realization method

An intelligent digital controller of a flexible material cutting robot, the controller being a network-based multi-core collaborative intelligent digital controller and comprising:

• an ARM chip, a servo driver bus communication module and a CPLD module;
• wherein
• the ARM chip has two built-in processor cores (Cortex-M0 and Cortex-M4) and is externally connected with a flash memory, an SD card, SRAMs and an Ethernet physical transceiver_2;
• the Cortex-M0 reads a corresponding graph in the SD card into SRAM_1 according to a graph number, and sends a graph data readiness interruption request to an interruption controller;
• and after the interruption request is responded, Cortex-M4 reads in graph data and conducts interpolation calculation on the graph;
• the servo driver bus communication module is used to receive an interpolation calculation result and transmit the calculation result to a data input end of a servo driver with a corresponding address number through a data sending port;
• and
• the CPLD module is used to read original point, terminal point and limit signals of a machine tool and store the read signal values in a shared space specified by SRAM_1.
