The invention relates to a segmented intelligent frequency scanning method for ultrasonic signal generators, and the method is applied to an ultrasonic signal generator connected with N ultrasonic transducers, wherein N is a natural number greater than or equal to 2. The method is characterized by comprising the following steps of: 1, a parameter presetting stage: setting parameters such as a frequency scanning start frequency fstart, a stop frequency fstop, a frequency scanning interval fstep, a pre-scanning frequency Ninit, a relative frequency difference RFD and a relative frequency step RFS; 2, a pre-scanning initializing stage: detecting fixed vibration frequencies of the N ultrasonic transducers connected with the ultrasonic signal generator at the same time, and sorting the fixed vibration frequencies of the N ultrasonic transducers in an ascending order; and 3, an intelligent frequency scanning stage: carrying out skip type or linear frequency scanning according to relative frequency difference betwee
