Abstract:An intelligent torque transmitting module based on ADuC7061 chip which own the ARM kernel was designed, which is aiming at solving the series of problems existed in the current torque module, such as low accuracy, poor universality, single function etc. This paper presented circuit and characteristics of the major components of the module. This module not only can realize range automatic switching and zero automatic calibration, but also can communicate via RS-485. In the working process of the module, each sampling period of the input analog signal could be independently modulated and converted by the ADuC7061 chip. The measured data by least-squares method determines the compensated sampled value for the torque cycle. The paper also gave the test specific data and correction effect diagram. Design of the whole system was concise, performance stability, only use such ADuC7061 a chip can complete the above a variety of functions, greatly reduce the cost.
