Wheel cable mobile structure video frequency monitoring system for damage

Abstract

The invention discloses a monitoring system of mobile type health video of a wheel cable, and can be used for monitoring the strain increment and corresponding deformation of injury, generation and development of cracks, designated points of the structure of all monitored parts of large-scale structures, such as bridges, houses, dams and so on, so as to further analyze the health of the structure and to warn the transfinite anomalies. The monitoring system comprises a wheel cable system which consists of a pulley and a cable, a traction power system which is used for driving the wheel cable system to operate, a shooting system which is fixed on the cable of the wheel cable system and is passively drawn, and a remote monitoring server which is arranged in a chamber; the shooting system is used for acquiring the video information of the tested structure through the moving wheel cable system according to instructions, and transmitting the information to the remote monitoring server; the remote monitoring server is used for comparative analysis and evaluation of the health status of the received information.

Description

technical field [0001] The invention relates to a cable mobile structural health video monitoring system, in particular to a cable mobile video system which can be used for short-distance and high-precision monitoring of bridges, dams and other structural health. Background technique [0002] Usually people will use the camera system to monitor the object that needs to be monitored, so as to know the situation of the object conveniently. However, if the scope of the surveillance object is huge, in order to implement global surveillance, it is necessary to set up a large number of cameras for surveillance. The installation of multiple cameras is likely to cause the problem of high monitoring costs. At the same time, when multiple cameras are used to implement global monitoring, only long-distance monitoring of the object under test can be implemented. For large objects in the field such as bridges, dams, and mountains, it is necessary to monitor the cracks, defects, relative...

Problems solved by technology

Although this equipment can achieve full-circle monitoring in special occasions that cannot be reached by people, it still needs to pull the connecting cable. The cable is easy to be entangled during use, and the cable needs to be replaced after long-term use. When the monitoring finds a defect, it cannot locate the defect. It can only be positioned with the help of additional measurement tools. In addition, the monitoring equipment can only monitor the part of the monitoring object, and cannot monitor the entire parts of the large monitoring object

[0004] The structural health monitoring system adopted at home and abroad is usually composed of various sensors installed on the structure to form structural information collection, information transmission, information reception, data analysis and health evaluation. The existing problems are high cost, difficult maintenance, and system Poor stability, difficult data analysis, cannot give people a structural state that seeing is believing, and the credibility is not high
