Handheld automatic incentive damage detector for structure damage detection

Abstract

The inventionprovides a handheld automatic incentive damage detector for structure damage detection. The handheld automatic incentive damage detector for the structure damage detection comprises a detector shell body, a control module and an automatic incentive damage detecting module, wherein the detector shell body comprises a lower plate, an upper cover, a handle, an LCD display screen, an adsorption selective switch and a detecting switch; the automatic incentive damage detecting module comprises a detecting module shell, a push-pull type electromagnet, an acceleration sensor, a sucked type electromagnet, a spring, a fixing slice and a fixed block; and the control module comprises an analog-digital conversion unit, a main control unit, a wireless communication unit, a photoelectric coupling unit and two solid-state relays. According to the handheld automatic incentive damage detector for the structure damage detection, the detector is small in size and can be conveniently carried to an area to be detected by an inspector, structure damage detection work is conducted on a detected surface through the automatic incentive damage detecting module of the detector, collected data aretransmitted to a server through wireless communication, thenanalyzing is conducted, the detecting efficiency is high, the size is small, carrying is easily achieved, and environmental suitability ishigh.

Description

technical field [0001] The invention belongs to the field of structural damage detection, in particular to a hand-held automatic excitation damage detector for structural flaw detection. Background technique [0002] With the rapid development of my country's economic construction, various complex and large-scale building structures continue to appear. Including some large bridges, large space structures, high-rise buildings, large railway transportation hubs, oil pipelines, nuclear power plants, etc. Since these building structures have high requirements for structural health, it is particularly important to strengthen structural health inspection and timely maintenance. [0003] At present, it is widely used to place wired or wireless sensor nodes in specific positions in buildings. This detection method has a detection blind spot and is difficult to maintain due to the fixed position of the sensor. The sensor node combines the detection device with the mobile robot. Thi...
