Controller for asynchronous stitch reading of computerized flat knitting machine

The utility model relates to a controller for asynchronous stitch reading of a computerized flat knitting machine. The controller comprises a processor and is characterized by further comprising a photoelectric sensor and a Hall sensor, wherein the photoelectric sensor is used for detecting a flat knitting machine ruler bar stitch position; the Hall sensor is used for detecting a flat knitting machine stitch end; the processor is connected with an FPGA (Field Programmable Gate Array) chip; the FPGA chip is connected with the photoelectric sensor and the Hall sensor so as to realize signal acquisition; the FPGA chip is connected with a driving module externally; the processor is connected with a host computer through a CAN (Controller Area Network) communication interface; and the processor is an ARM7LPC2292 (Advanced RISC Machine 7 Linear Power Controller 2292). The controller structurally adopts the FPGA chip in high speed calculation to realize the acquisition of a ruler bar encoding sensor and a stitch Hal
