The invention provides a spindle moment telemetering method based on WIFI and a data pushing mode. A rotation measuring part that is fixed on a spindle and rotates with the spindle, a fixed receivingpart based on a WIFI wireless router, an annular rotary transmitting system fixed on the spindle, a fixed annular receiving antenna system sleeving the outside of a transmitting antenna, and a lithiumbattery power supply unit with a real-time charging function are arranged. According to the telemetering method, a moment measurement sensor unit, a data amplification unit, an A/D conversion unit, atransmission unit, a processing and application unit, a data push mode, a data transmission and receiving unit, and a lithium battery power supply unit for real-time charging are arranged. Accordingto the invention, the measuring method is simple and effective; the data are pushed actively; with the concentric annular antenna system, the WIFI data stability is ensured; the power supply system with the real-time charging function provides reliable power supply; the influence by the slip ring contact resistor is eliminated and the problem of pollution on the environment by the mercury is solved; the accuracy of the spindle moment direct measurement system is improved; and the system cost is lowered.
