Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a method and a device for monitoring the motion state of a synchronous clutch and electronic equipment, which can calculate and output the motion parameters of an internal middleware in real time in the process of engaging and disengaging the clutch and provide effective data support for the fault early warning and fault analysis of the clutch. Specifically, the synchronous clutch of the combined cycle unit realizes the relative motion of the intermediate part based on the rotating speed difference of the driving part and the driven part, and completes the engagement and disengagement of the driving tooth and the driven tooth. When the rotating speed of the driving part is greater than that of the driven part, the intermediate part makes spiral motion relative to the driving part along the spiral spline to the driving part, and the clutch performs meshing action; when the rotating speed of the driving part is lower than that of the driven part, the intermediate part makes spiral motion relative to the driving part along the spiral spline to the driven part, and the clutch performs disengagement action. Because the physical structure of the helical spline is fixed, the relative motion angular displacement of the intermediate piece is constant in the engaging and disengaging processes of the clutch, so that the monitoring of the motion state of the intermediate piece can be realized through calculation and analysis of the relative motion angular displacement, the angular velocity and the angular acceleration of the intermediate piece, and the state of the synchronous clutch can be further monitored.

In step S103, the state of the synchronous clutch is monitored based on the angular displacement curve of the intermediate member.
In the embodiment of the invention, the rotating speed of a driving part and the rotating speed of a driven part of the synchronous clutch are firstly obtained, then the angular displacement curve of an intermediate part of the synchronous clutch is determined according to the rotating speeds of the driving part and the driven part, and finally the state of the synchronous clutch is monitored according to the angular displacement curve of the intermediate part. According to the embodiment of the invention, the motion state of the intermediate piece of the synchronous clutch can be monitored difficultly through the rotating speed of the driving piece and the rotating speed of the driven piece, so that the whole motion state of the synchronous clutch can be monitored, the fault of the synchronous clutch can be monitored in time, and potential safety hazards are effectively avoided.
