Abstract
A monitoring method of a thimble base includes the following steps: arranging a reflective surface on a thimble head of a thimble base; arranging at least a light source and a receiver on the thimble base; establishing a reflection path between the thimble bases to project light onto the reflective surface of the thimble head of one of the thimble bases in the reflection path, so that light is reflected between the reflective surfaces and is finally reflected to the receiver. The disclosure also provides a monitoring apparatus of the thimble bases. The monitoring apparatus includes a carrying platform, thimble bases arranged in an array on the carrying platform, and at least one light projecting and receiving device. Compared with the prior art, the disclosure realizes real-time monitoring of the thimble bases, thereby avoiding the problem of fragmentation caused by deformation of the thimble bases.
