Background technique [0002] In the fields of transportation, manufacturing and scientific research, it is often necessary to measure the operating parameters of various rotating shafts, such as measuring the rotational torque, axial force, vibration, temperature, pressure, speed and other parameters of the rotating shaft, in order to know The health of the rotary axis. Especially in large-scale mechanical production equipment, due to the heavy workload and long working hours of each rotating shaft in the equipment, it is necessary to obtain real-time parameters such as vibration, torque, pressure and axial force of each rotating shaft in the mechanical equipment during operation , and monitor the safety performance of the mechanical equipment in real time according to this par...

AI Technical Summary

Problems solved by technology

Due to the need to fix the coil windings on the rotor and the stator separately, it is difficult to manufacture the toroidal transformer, and the volume and weight of the toroidal transformer are large, and the moment of inertia is also large, so it cannot be applied to the measurement of high-speed rotating and light-weight rotating shafts; at the same time, The coupling efficiency of the toroidal transformer is not high, and it is easy to generate heat. The electromagnetic field generated by the transformer itself will also interfere with parameter measurement, affecting the accuracy and stability of signal measurement.

Moreover, each toroidal transformer can only realize the coupling transmission of one measurement signal at the same time. When multiple parameters need to be measured at the same time, it is necessary to install multiple sets of toroidal transformers, which will inevitably aggravate the seriousness of the above problems.

[0006] To sum up, in the existing measuring devices, the measurement transmission mode of the conductive slip ring has a short life and is easily damaged, while in the toroidal transformer coupling transmission mode, the toroidal transformer is difficult to manufacture and assemble, has a large inertia and volume, and cannot achieve high-speed , the measurement of light-weight rotating shafts, and the measurement of each parameter in the prior art requires a separate output device. When multiple parameters are measured and output, it will inevitably cause the measurement equipment to be large in size and high in cost. At the same time, the prior art There are signal interference problems in the signal transmission process, and the measurement of parameters and the accuracy and stability of transmission cannot be guaranteed.
