The invention relates to a total-
stroke and total-space transient electromagnetic device and measuring method. The device comprises a transmitting unit and a multi-channel receiving unit, wherein the transmitting unit and the multi-channel receiving unit are respectively connected with a
signal processing unit, the
signal processing unit is connected with a main engine through a
communication unit, relevant parameters are set through operation
software of the main engine, the receiving unit and the transmitting unit jointly achieve field source excitation and complete collection, recording and the like of an induction
signal and an excitation source signal, the induction signal and the excitation source signal are transmitted to the main engine through an RS485, and the display, storage, management and the like of the data are achieved. According to the total-
stroke and total-space transient electromagnetic device and measuring method, the self-induction and mutual induction influences can be effectively reduced, the
signal to noise ratio and the sensitivity are improved, receiving coils can be combined into different types according to the detection requirement, the different detection effects can be obtained, and the judgment on the direction of an abnormal body can be achieved under the total-space situation. The number of detection blind zones can be reduced, the superficial zone detection effect can be improved, an ARM quad-core processer hardware platform is adopted, a special embedded type operation
system is configured, and real-time imaging, comparison, judgment and subsequent analysis can be conveniently carried out on the measured data.
