After rectification and voltage stabilization, this voltage provides operating power to the two circuit boards, signal processing circuit board one and signal processing circuit board two, in the second circuit board 310. The signal processing circuit board two is connected to a rotating component signal acquisition sensor. This sensor is configured with eight signals and can be arranged on the rotating part of the rotating component.

The light signals pass through the receiving coil 311 and the transmitting coil 308. The optical signal is transmitted to the first circuit board 306 through the through hole. The first circuit board 306 receives the optical signal and converts it into an electrical signal, which is then transmitted to an external control system or display terminal to realize data visualization or control feedback.

[0028] Furthermore, one end of the rotating shaft 312 is fitted into the inner side of the bearing 303. Two sets of bearings 303 are provided. Through the arrangement of bearings 303, the bearings 303 are installed inside the mounting head 2.

It is responsible for powering and controlling the laser signal source 309 and the transmitting coil 308, and is electrically connected to an external power source through the waterproof outlet 305 to realize the power input and control of the entire device.

[0032] Furthermore, the second circuit board 310 is provided in two sets. One side of the surface of the rotating shaft 312 extends through the second circuit board 310. The second circuit board 310 is positioned on both sides of the integrated cavity 307, extending through the rotating shaft 312, and is used to process laser emission signals, realize signal conditioning and conversion, and provide electrical signal support for subsequent data output to ensure the stability and accuracy of measurement data. The second circuit board 310 contains a signal processing circuit board one and a signal processing circuit board two. The signal processing circuit board two has a "sensor signal input terminal" that connects to the "surface of the rotating device or pre-embedded sensor wiring," and can receive signals from sensors one to eight. The signal processing circuit board one obtains power through a "power input terminal" and has a "laser signal output terminal," which can transmit the processed signal to the corresponding interface "connection terminal block" of the signal processing circuit board two via a "connection terminal block." Simultaneously, the driving signal generated by the signal processing circuit board is connected to the "laser body emission", thereby generating a laser signal for laser transmission via the "laser signal input wiring". The signal is received by the first circuit board 306 (which is the "laser receiver" in Figure 5), and after photoelectric conversion and decoding, the receiving device performs subsequent signal processing.

Laser signals have advantages such as strong anti-interference ability, good safety performance, fast transmission rate, large information capacity of the load, low transmission loss, long-distance transmission, non-contact, and low cost, and are used for signal transmission in complex interference environments.

[0036] Furthermore, the transmitting coil 308 and the receiving coil 311 are powered without contact. The receiving coil 311 is electrically connected to the second circuit board 310. In use, the power generated by the receiving coil 311 provides power to the two circuit boards of the second circuit board 310. The transmitting coil 308 can convert the DC input signal into a constant AC power through an inverter circuit and a power management chip, and then convert the electrical energy into a high-frequency AC signal. The signal is transmitted to the receiving coil 311 through the transmitting coil 308. The receiving coil 311 converts the high-frequency signal into electrical energy through inductive coupling, and then outputs the DC power required by the acquisition board through a rectification and voltage regulation chip management circuit. The transmitting and receiving circuits should also include a tuning circuit to ensure the resonant frequency of the transmitting coil 308 and the receiving coil 311, as well as other auxiliary circuits such as safety protection and reverse connection prevention.

[0037] Working principle: After the device is powered on, the external power supply provides operating power to the first circuit board 306 and the transmitting coil 308 in the main housing 1. The transmitting coil 308 induces a voltage in the receiving coil 311 in the measuring mechanism 3 through inductive power supply. After rectification and voltage regulation, this voltage provides operating power to the two circuit boards, signal processing circuit board one and signal processing circuit board two, in the second circuit board 310.

[0038] A signal acquisition sensor is connected to the rotating component. The sensor is configured to receive eight signals and can be placed on the rotating part of the rotating component. The acquired signals are processed by the signal processing circuit board and converted into driving signals to drive the laser signal source 309 to generate light signals. The light signals are transmitted to the first circuit board 306 through the through holes of the receiving coil 311 and the transmitting coil 308. The first circuit board 306 receives the light signals and converts them into electrical signals, which are then transmitted to an external control system or display terminal to realize data visualization or control feedback.
