ANGLE MEASURING APPARATUS AND METHOD THEREOF AND ENGINEERING MACHINERY

An angle measurement device includes a microprocessor (100), a primary acceleration transducer (210), an output device (300), and an auxiliary acceleration transducer (220). There is a predetermined angle between a positive direction of a primary sensitive axis of the primary acceleration transducer (210) and that of a auxiliary sensitive axis of the auxiliary acceleration transducer (220); the primary acceleration transducer (210) and the auxiliary acceleration transducer (220) output respectively a first initial parameter and a second initial parameter; the microprocessor (100) obtains a first actual parameter of the primary acceleration transducer (210) according to the first initial parameter, the second initial parameter and the predetermined angle and then gets an angle parameter according to the first actual parameter; the first actual parameter characterizes the parameter of the primary acceleration transducer (210) in the case of no external interference. An angle measurement method and a construction machinery with the angle measurement device is also provided. The provided angle measurement device and method can obtain measuring result in dynamic state accurately.
