Zusammenfassung:The embodiment of the invention discloses a non-contact button of an elevator calling system, a non-contact elevator calling system and elevator equipment. The non-contact type button comprises an oscillating circuit and a microprocessor, the oscillating circuit comprises an inductance coil and is used for outputting an elevator calling signal, the frequency of the elevator calling signal changes along with the change of a magnetic field detected by the inductance coil, and the microprocessor is electrically connected with the oscillating circuit and is used for generating an elevator calling instruction according to the frequency change of the elevator calling signal and outputting the elevator calling instruction. According to the technical scheme provided by the embodiment of the invention, non-contact information identification and calling of the elevator are realized, contact between a human body and elevator buttons is avoided, the service life of the elevator equipment is prolonged, and propagation of
