The working principle of the group of radiationless fetal rhythm instruments provided by the embodiment of the invention is as follows:

firstly, the first fixing belt 2 and the second fixing belt 3 are positioned at the upper part and the lower part of the belly of a pregnant woman, and the waist plate 1 is positioned at the waist of the pregnant woman, so that the pregnant woman can wear the pregnant woman more comfortably;

secondly, through the length of adjusting the bellows 22 at first area body 21 both ends of first fixed band 2 and second fixed band 3 for the size of pregnant woman's belly is adapted to more to first area body 21 of first fixed band 2 and second fixed band 3, and accommodation is wider.

Then, the control button 23 is pressed, so that the electrocardiogram monitoring device carries out fetal heart monitoring through the sensor 422; exemplary, as shown in FIG. 7; when the sensor 422 obtains data measured at a1, the data is transmitted to a processor for processing, and the processed measured data is sent to the cloud end through the control system; when the data at the position A2 needs to be measured, the control system is started, the first electromagnet 13 is electrified, and the repulsion force is generated on the first magnet 25; two groups of first belt bodies 21 fixed in the upper cavity 17 and the lower cavity 18 are far away from the first electromagnet 13, so that a gap is formed between the two groups of first belt bodies 21 and the belly of the pregnant woman, and the displacement of the sensor 422 is facilitated; at this time, the control system energizes the second electromagnet 433 again according to the moving path, for example, to move the sensor 422 from a1 to a5, the second electromagnet 433 at a1 is de-energized, the second electromagnet 433 at a4 is energized, the second electromagnet 433 at a4 generates attraction force, the sensor 422 moves to a4 by the attraction force, and the second electromagnet 433 at a4 is de-energized to lose the attraction force; finally, the second electromagnet 433 of a5 is energized to generate attraction force, so that the sensor 422 of a4 moves to a5, the energized state of a5 is released, the sensor 422 is fixed at a5 through the magnetic latch 423, the sensor 422 can measure data of a5, and similarly, the sensor 422 can move from a5 to A3 and then move to a 2. The measuring range is wider, and the data accuracy is higher. At the same time, discomfort caused by the skin in the same location contacting sensor 422 for a long time can also be avoided.

After waiting for sensor 422 to move to relevant position, make first electro-magnet 13 not circular telegram through control system, the repulsion disappears, first magnet 25 attracts mutually with first electro-magnet 13 for two sets of first areas body 21 drive sensor 422 and skin laminating, carry out the measurement of child heart data.
