Claim Text:
1. An automatically identifying Fetal Heart Rate (FHR) baseline apparatus, comprising a FHR data collecting module; a FHR data preprocessing module; a primary dominant peak value selecting module; a dynamic baseline identifying module and a main control module; wherein the FHR data collecting module is connected with the main control module, is configured for collecting the FHR data within a preset duration, further obtains FHR data sequence h′(n), and transmits the FHR data sequence h′(n) to the main control module; wherein the FHR data preprocessing module is connected with the main control module, is configured for preprocessing the FHR data sequence h′(n) transmitted by the main control module, obtains the preprocessed FHR data sequence B(m), and transmits the corresponding results obtained during preprocessing to the main control module; wherein the primary dominant peak value selecting module is connected with the main control module, is configured for selecting the primary dominant peak value according to the frequency distribution of the corresponding results obtained during preprocessing that the main control module is transmitted, and transmits the results to the main control module; wherein the dynamic baseline identifying module is connected with the main control module, is configured for working out the filtering start point T according to the primary dominant peak value transmitted by the main control module, carries out low pass filtering and data recovery for the preprocessed FHR data sequence B(m) to further obtain the dynamic FHR baseline, and transmits the results to the main control module; and wherein the main control module is connected with the FHR data collecting module, the FHR data preprocessing module, the primary dominant peak value selecting module, the dynamic baseline identifying module and a displaying/printing module, and configured for controlling the operation of the FHR data collecting module, the FHR data preprocessing module, the primary dominant peak value selecting module and the dynamic baseline identifying module.
