The present invention relates to the field ofbio-medical signal processing, particularly relates to an apparatus and method for automatically identifying FHR baseline, comprising: collecting FHR data within a preset duration to obtain an FHR data sequence h (n) preprocessing the collected FHR data sequence h (n) to obtain a corresponding FHR data sequence during the preprocessing selecting a primary dominant peak value according to the frequency distribution of the corresponding FHR data sequence during the preprocessing and identifying a dynamic baseline according to the corresponding FHR data sequence and the primary dominant peak value during the preprocessing to obtain the dynamic baseline, and display and print the dynamic baseline. The technical solution provided in the present invention effectively prevents the impact caused by regular change of the FHR to the baseline solution, and accurately reflects the FHR baseline and changes thereof of a fetus under different conditions.
