Iron core magnetic field detection method based on excitation signals

The invention provides an iron core magnetic field detection method based on excitation signals. The iron core magnetic field detection method comprises the following steps of: (1) performing signal acquisition; (2) determining whether the working environment of an iron core is abnormal or not according to environment temperature and environment humidity, and giving out an alarm; (3) judging whether the magnetic field of the iron core is normal or not; (4) determining the type of excitation signals; (5) calculating the loss of the iron core according to different excitation signals; and (6) judging whether the iron core works abnormally or not according to the loss of the iron core . With the iron core magnetic field detection method based on the excitation signals adopted, the abnormality of the iron core can be fund out timely, so that the better work of equipment can be guaranteed. 本发明提供了一种基于激励信号的铁芯磁场检测方法，包括以下步骤：(1)：信号采集；(2)：根据环境温度、环境湿度确定所述铁芯工作环境是否异常，并报警；(3)：判断所述铁芯磁场是否正常；(4)：确定所述激励信号类型；(5)：根据不同的所述激励信号计算所述铁
