Method, system and device for monitoring mechanical structural parts using rfid tags

Abstract

The invention discloses a method, system and device for monitoring mechanical structural parts by using RFID tags, which can be used for fixed-length or fixed-shaped fasteners that bear tension, compression, twisting, shearing and other forces in mechanical devices that bear mechanical and motion loads , to monitor. This solution uses RFID tags with customized shapes, and uses the characteristics that the communication status of RFID tags is extremely sensitive to changes in circuit or antenna size and shape, to form a solution to the small displacement, looseness, loss, Real-time perception and detection of fracture and other states can achieve real-time monitoring of the safety status of mechanical devices. By adopting this scheme, the positioning and continuous monitoring of key fasteners or structural parts in the mechanical device can be carried out at low cost, and an alarm can be issued in time to avoid further damage to the faulty structure and cause catastrophic accidents. This solution is suitable for monitoring scenarios of various mechanical devices including heavy-duty mechanical devices involving personal safety.

Description

technical field [0001] The invention relates to the technical field of mechanical structure safety monitoring, in particular to a method for monitoring mechanical structural parts by using RFID tags, an RFID reliability monitoring system and a mechanical device with the RFID reliability monitoring system. Background technique [0002] Mechanical structures are very common in modern society. The reliability of some mechanical structures directly affects the working efficiency of equipment or devices. Sudden damage to some key mechanical structures can lead to loss of function in light cases, or accidents in severe cases, resulting in serious personal injury or death. or environmental disasters, such as: the tower structure of the power and communication system is broken due to bolts, which may cause the tower to be unstable and collapse, resulting in interruption of power and communication; If the block bolt breaks, it may cause the ladle to overturn; if the elevator track fi...

Problems solved by technology

[0003] Early warning diagnosis and all-weather monitoring of mechanical structures have always been the ultimate goal of equipment safety supervision. However, due to the previous technology, specific sensors must be used for monitoring. These devices are expensive, require too many environmental resources, and cannot be widely used. Generally speaking, in order to achieve all-round monitoring of the above-mentioned equipment and structures, it is likely that the cost for the construction of the monitoring system will far exceed the cost of the equipment itself
