Description

Object wear detecting device

The invention relates to a detection technology for the degree of wear of an object, in particular to an object wear detecting device.

Generally speaking, when an important object is seriously worn due to frictional contact, it is easy to endanger the safety of use; for example, when the tire of the vehicle is severely worn, it often causes slipping, increasing fuel consumption, and even causing a car accident; For example, when the mechanical devices of the factory are seriously worn, they often have malfunctions and even work safety events.

In order to avoid this, usually important objects use manual or instrument to detect the wear of the object. The method of manual detection is to pre-insert objects of special color or material in a specific depth of the object. When the object wears to a certain depth, the embedded object will be exposed to remind the object that the object has been worn seriously. However, the method of manual detection is difficult to achieve immediate warning.

In addition, the method of detecting the instrument is to replace the human eye with an image detecting instrument to detect whether an object embedded in a specific depth of the object is exposed, but such an image detecting instrument misjudges when detecting a high-speed moving object. The rate will increase dramatically, and such image detection instruments are more expensive.

Another type of detection is to implant a sensor, wireless communicator or optoelectronic device at a specific depth of the object to transmit the wear of the object to the corresponding reader at any time. However, sensors, wireless communicators, or optoelectronic devices all have batteries that fail when the battery is terminated and cannot be detected.
