Control system of groove drum motor of doubling winder

The utility model relates to a control system of a groove drum motor of a doubling winder. The control system comprises a microprocessor, a power supply conversion module, a 485 communication module,a relay communication module, two brushless motor driving modules, an encoder signal acquisition module, two current sampling modules and a data storage module, the microprocessor carries out serial port communication with other communication devices through the 485 transceiver circuit, carries out communication through the relay communication circuit, obtains a current signal through current sampling, current amplification, filtering, amplitude limiting and ADC conversion in sequence, and is connected with a Hall signal interface through the optocoupler isolation circuit to input a Hall signal. A brushless motor MOS tube driving chip is connected with a brushless motor driving interface to output control signals, and the brushless motor MOS tube driving chip is connected with an externalstorage chip through an II
