The invention relates to a digitalized detection method for the temperature information of a micromechanical quartz gyroscope sensitive device, belonging to the fields of inertial sensor devices and signal processing. The digitalized detection method comprises the steps of: establishing a closed-loop driving module composed of a quartz tuning fork, an analog circuit, an ADC (Analog to Digital Converter), a DAC (Digital to Analog Converter) and a digital signal processing unit, generating sinusoidal signals close to resonant frequency by adopting a digital signal processing method, driving thequartz tuning fork to work, feeding back and compensating to make a tuning fork work at a fixed-amplitude state, detecting voltage quantity after a driving signal is subjected to the current voltage transformation of the turning fork, and reflecting temperature information by utilizing a amplitude variation factor g of the voltage quantity. According to the invention, the precision and the flexibility of the quartz tuning fork gyroscope in temperature compensation can be obviously increased; hardware do not need to be changed for the tuning forks of different properties, and a calibration coefficient is only need to provide in an algorithm; and if a user do not need to be provided with temperature, the amplitude variation factor g can be directly applied inside a digital signal processingunit to carry out temperature compensation, and additional devices do not need to be added.
