[0046] Referring to FIG. 9 , the electromagnetic transmitter 43 includes a transmitting tube 431 and a plurality of coils 432 wound on the transmitting tube 431 , and a photoelectric sensor is installed in front of each coil 432 of the transmitting tube 431 , and the plurality of coils 432 on the transmitting tube 431 are closed by a magnetic shielding sleeve 433 , and the surface of the collecting bullet 44 is wrapped with ferromagnetic material, so that the collecting bullet 44 is launched in the transmitting tube 431 , and when the collecting bullet 44 passes through each photoelectric sensor, the corresponding coil 432 behind it is powered off, so that the collecting bullet 44 The collection bullet 44 is accelerated by multiple sets of coils 432 to be launched far enough to collect data far from the detection point.
