【 摘 要 】

In view of the disadvantages of high fault rate of tie-line and angle dynamometer and high-power consumption of the wireless dynamometer in normal mode, a kind of wireless dynamometer with low-power mode is designed. The dynamometer can measure dynamometer card and transmit data not only according to commands received but also automatically according to the established procedure. A kind of comprehensive filtering algorithm is designed, which can effectively remove high-frequency and peak interference of the acceleration data. The hardware circuit, working mode and filtering algorithm are detailed. Tests of energy consumption and dynamometer card are given. The field application shows that the device has the advantages of high reliability, accurate measurement and low-power consumption.
