Research Of A New Type Of Dynamic Torque-speed Sensor

Torque measurement is the optimization of various mechanical product development, quality inspection, control and condition detection and fault diagnosis, essential contents, also is one of the important content in the transmission line, through the analysis of torque, the entire transmission system performance parameters can be obtained. As the modern industrial production automation and intelligent degree is increasing day by day, more and more people need to get the information, which requires measuring system with real-time online detection, dynamic data processing functions. Dynamic torque measurement from contact measurement to non-contact measurement development, develop in the direction of the real-time monitoring measurement system. In this paper, the main research contents include:(1)Introduced the structure and measuring principle of double eccentric dynamic torque sensor, and analyses the influence of the sensor signal acquisition system requirements.(2)Put forward a method based on hall sensor signal acquisition, analysis the feasibility of this principle, design a signal acquisition based on hall element. And the feasibility test head collected.(3)Designed the two kinds of information collection system, in this paper, the principle of the scheme, the feasibility is analyzed. According to the selected scheme design the signal conditioning circuit and STC12C5A60S2 micro controller based systems. The hall sensor output sine signal filtering, such as blocking, comparison and logical processing.(4)Using single chip c language programming, complete signal collection, calculation, display, and other functions.(5)On the dynamic torque sensor test bench to debug information processing system. The installation and debugging information acquisition, signal conditioning circuit for the debugging and modification; The noise of the software are verified, appeared to signal was tested by adopting the method of the shield.Through experimental analysis, the principle of the dynamic torque sensor signal acquisition head is feasible and easy to realize signal acquisition. How to realize anti-jamming, improve reliability still need further test.
