Description

technical field [0001] The present application relates to a monitoring technique for monitoring the condition and performance of a linear motion system. Background technique [0002] Linear motion systems play an extremely important role in factory automation. For example, linear motion systems enable the automated workflow link between machine tools and subsequent processing equipment to achieve high process efficiency. During the operation of the linear motion system, it is necessary to monitor the parameters of the linear motion. Existing linear systems often have sensors to monitor motion parameters, and these sensors are usually installed independently of each other in the linear system to measure different motion parameters respectively. [0003] For example, in one solution of the prior art, the displacement of the linear motion is determined by recording the rotation angle of the motor through a PLC (Programmable Logic Controller) in the linear motion system.

Problems solved by technology

These parts are sensitive to dust and require significant changes to linear motion products in terms of installation, which is expensive, complicated to operate, and difficult to maintain.

[0004] It can be seen that the existing linear motion system requires a complicated scheme to measure a single specific parameter separately, which is costly and complicated

Moreover, analysis processing based on these measured parameters often requires a lot of work to achieve a match between the measurement results and the actual application
