[0059] With the goal of collecting speed and position signals of moving parts in real time at the millisecond level, we first ensure that the electromagnetic tactile detection sensor does not directly contact the detected part (1mm gap). The electromagnetic tactile sensor is far away from the detected part to ensure that its detection signal is not interfered with by the harsh 3D environment. At the same time, there is a self-maintained compressed air system for cooling and dust blowing to ensure that its operation is sensitive, stable and reliable. The detected part must be in close contact with the detection mechanism to ensure detection accuracy, and the detection mechanism has self-maintained compressed air cooling, lubrication and oil replenishment, and a flexible reset device to ensure that the detection process is impact-free, sensitive, stable and reliable. The entire device and the self-maintenance system are highly coordinated to ensure that the millisecond-level real-time transient signal acquisition is accurate, stable and long-lasting, and can be fine-tuned to meet the application of multiple working scenarios of straight lines and arcs.
[0060] Among them, a compressed air cooling and purge circuit and a lubricating grease oil supply and drainage circuit are designed and manufactured inside the base of the self-maintenance device to realize self-maintenance of the collection device system.
[0061] The self-maintenance device base separates the non-contact electromagnetic induction switch from the detected component, ensuring that the electromagnetic induction switch signal acquisition is not affected by high temperature dust in harsh environments and differences in the detected components.
[0062] The electromagnetic induction switch protective cover and the self-maintenance device base work together to form a positive pressure cooling cavity purged with compressed air, further protecting the electromagnetic induction switch and cable to ensure that the collected signal is not interfered with.
[0063] The triangular structure of the contact block of the inspected component fits the moving part to ensure close contact and smooth operation. The block can be replaced regularly if its current strength is lower than that of the inspected component.
[0064] The upper and lower compressed air cooling circuits of the self-maintenance device base are connected through 32 connecting pipes, which ensures the uniformity of cooling of the self-maintenance device base and ensures that the signal acquisition mechanism is not affected by uneven stress and reduces the flexibility and accuracy of the signal acquisition mechanism.

[0126] The triangular structure of the contact block of the inspected component fits the moving part to ensure close contact and smooth operation. The block can be replaced regularly if its current strength is lower than that of the inspected component.
[0127] The upper and lower compressed air cooling circuits of the self-maintenance device base are connected through 32 connecting pipes, which ensures the uniformity of cooling of the self-maintenance device base and ensures that the signal acquisition mechanism is not affected by uneven stress and reduces the flexibility and accuracy of the signal acquisition mechanism.
[0128] The invented self-maintenance system is highly compatible with the signal acquisition device, ensuring reliable and sensitive millisecond-level signal acquisition and guaranteeing the stable working state of the refueling robot.
