【Abstract】 A new kind of torque sensor based on simple structure and high measuring accuracy that uses the Programmable Logic Devices to process data sign is introduced, which is called the measuring system of grating torque sensor. Firstly, it explains the principle and characteristic of the programmable logic devices,then it introduces the principle and structure of grating torque sensor,finally it describes the correlative technology of the applied design of the PLD and the realization of this system. According to the results of experiments,the application of the PLD has the simpler structure and the better capability and the better secrecy than those separate elements,which is an ideal electrocircuit design method.更多还原
