Screw, bolt and detection system thereof

Abstract

The invention discloses a screw, a bolt and a detectign system thereof. A method comprises the following steps: arranging a sensing material in the screw or the bolt, supplying power through a radio-frequency circuit; utilizing a signal processing unit to convert an electrical signal from the sensing material into a readable signal of the circuit; and transferring the readable signal to an external detecting device through the wireless radio-frequency, so as to detect state of the fixed element. By adopting the method, the mass screening actions can be performed accurately and quickly to the fixed element. Furthermore, the invention is particularly suitable for high safety considering places, for example, some screws on an airframe.

Description

technical field [0001] The invention relates to a technology for detecting the fixing state of a fixing element, in particular to a fixing element with a force-electricity conversion sensing material and a detection system thereof. Background technique [0002] Fixing elements are the basis of industrial products, whether it is toys or even large industrial devices, such as transportation tools such as aircraft or marine appliances, are closely related to fixing elements. Especially on aircraft, the role played by the fixing element is very important. As long as a fixing element is loose, it may cause immediate flight safety danger to the aircraft, and then affect the safety of the life and property of passengers on the aircraft. On August 28, 2007, the U.S. Federal Aviation Administration (FAA) issued a rare emergency airworthiness instruction again, requiring Boeing 737-600 and above passenger planes to complete the front wing seam fixing bolt nut special feature within te...

Problems solved by technology

In addition, the screw needs to be tightened with a torque wrench, and some screw heads will also have alignment paint to visually check whether it is loose, but these are all based on the premise that the components can be seen visually on the flight-line repairable parts If it is within the structure of the aircraft or the internal parts that are not visible at all levels of inspection, it is completely inaccessible unless it is disassembled for general inspection or special inspection. If it is really bad design, the lives of passengers will be endangered. major crisis
