An electromagnetic spring lunar soil penetrating device with a pressure sensing function comprises a power module, a penetrating module and a control module, the power module comprises a lower shell and an upper shell, a first electromagnet and a second electromagnet are fixed to the lower end of the lower shell and the upper end of the upper shell respectively, and an impact hammer is slidably connected between a first guide rail and a second guide rail; the injection module comprises a storage roller and a thin shell; the control module comprises a PLC (Programmable Logic Controller), a displacement sensor and a pressure sensor; the PLC receives the angle signal and the pressure signal and controls the motor to adjust the release length of the thin shell, the PLC drives the permanent magnet to drive the impact hammer to move up and down by controlling the current magnitude and direction of the first coil and the second coil, and the impact hammer impacts the clamp holder to drive the thin shell to penetrate into lunar soil; according to the lunar soil penetrometer control method, the thin shell is driven to penetrate into lunar soil by controlling the magnitude and direction of electromagnetic force; compared with a traditional energy storage spring structure, the lunar soil penetrometer has the advantages that the penetration precision can be improved, the hysteresis phenomenon is remarkably improved, and the self-adaptive adjustment function is achieved.
