The invention relates to the technical field of compressor control, in particular to a reverse blowing pulse control system and method for a Roots compressor, and the reverse blowing pulse control system comprises a central control unit and a pulse signal output unit; the central control unit outputs at least sixteen paths of pulse control signals according to the feedback signals of the compressor; and the pulse signal output unit is used for outputting a reverse purging pulse signal according to the pulse control signal. The central control unit and the pulse signal output unit are utilized, the reverse blowing pulse signal is output according to the compressor feedback signal, the reverse blowing equipment of the Roots compressor is controlled to execute reverse blowing work, and therefore the independent reverse blowing control system is formed; according to the reverse blowing control system, the compressor feedback signal is directly utilized to output the reverse blowing pulse signal to the reverse blo
