Description
本發明涉及一種物件磨損程度的檢知技術，特別是有關於一種物件磨損偵測裝置。The invention relates to a detection technology for the degree of wear of an object, in particular to an object wear detecting device.
一般來說，當一個重要的物件因磨擦接觸而造成嚴重磨損時，就容易危及使用安全；例如車輛的輪胎在磨損嚴重時，就會經常出現打滑現象，增加耗油量，甚至發生車禍；又例如工廠的機械裝置在磨損嚴重時，就經常出現誤動作，甚至發生工安事件。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.
為避免上述情況發生，通常重要的物件會利用人工或儀器來偵測物件的磨損狀況。人工偵測的方式是預先在物件的特定深度中植入特殊顏色或材質的物體，當物件磨損嚴重至特定深度時，預埋的物體就會外露，以提醒物件已磨損嚴重。但是人工偵測的方式難以實現即時警示。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.
另外，儀器偵測的方式是利用影像偵測儀器取代人眼，來偵測物件的特定深度中所預埋的物體是否外露，但是諸如此類的影像偵測儀器在偵測高速移動的物件時，誤判率會大幅提升，且此類的影像偵測儀器更是價格不菲。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.
另有一類的偵測方式是在物件的特定深度中植入感測器、無線通訊器或光電器，以隨時傳送物件的磨損狀況至相應的讀取器。然而感測器、無線通訊器或光電器都具備電池，當電池壽命終止時，也就失效而無法再進行偵測。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.
本發明之目的在於提供一種成本低廉，不會因為電池壽命終止而失去偵測功能，且可產生警示信號之物件磨損偵測裝置。SUMMARY OF THE INVENTION It is an object of the present invention to provide an object wear detecting device which is inexpensive and which does not lose its detection function due to the end of battery life and which can generate a warning signal.
