Abstract

The invention relates to the technical field of signal processing and provides a method for the high-precision transmission of a rotating part signal. The method comprises a step of installing one ormore sensors for data acquisition on a rotating component, a step of sequentially arranging a signal conditioning module, a processor and a wireless transmission module at a signal output end of the sensor and forming a data transmission line by combining external processing equipment, and a step of establishing a power transmission line by using an external power supply. According to the invention, the signal conditioning module is additionally arranged at a rear side of the data acquisition end, preferably, a fixed precision amplifier is additionally arranged in a conductive slip ring, and asignal is converted into a signal which is not interfered or is difficult to be interfered after being preprocessed by the amplifier, so the high-precision transmission of the rotating part signal can be ensured, meanwhile, the independent design of the data transmission line and the power transmission line is utilized to realize the transmission separation of the signal and a power supply, and therefore, the overall anti-interference performance is further improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method for high-precision transmission of rotating component signals. Background technique [0002] For various means of transportation containing wheels, such as road vehicles, rail locomotives, and airplanes, if the signal of the wheel is to be transmitted, in some rotating structures, the signal cannot be transmitted by wire due to the rotational motion, and a conductive slip ring is required to complete the signal. Conductive slip rings are also widely used in robotics, wind power and military fields, such as industrial manipulators, military satellite tracking, medical equipment scanning systems, aerospace vehicle tracking systems, etc. [0003] Due to the high-speed friction between the inner and outer rings, the contact conductive slip ring will generate heat and noise, and it will be easily deformed after a long time, affecting the tightness of the contact, th...
