Abstract
Abstract With the technological evolutionary advent, a vision-based approach presents the remote measuring approach for the analysis of vibration. The structure vibration test and model parameter identification in the detection of the structure of the bridge evaluation occupies the important position. The bridge structure to operate safely and reliably is ensured, according to the geological data of qixiashan lead-zinc mine and engineering actual situation, with the aid of international mining software Surpac. To build the 3D visualization model of the application of visualization in mine production are discussed. The results show that the final solid model of -425 stope can accurately display the spatial form of each layer of stope through rotation, amplification and movement. The proposed system is effectually able to perform cutting, volume calculation and roaming in any direction, which has certain guiding significance for mine production management. An accuracy value of 98.75%, the sensitivity of 99%, specificity of 99.64% and PPV of 99.89% are achieved using the proposed 3D modelling and visualization algorithm for vibration signal processing and management.
Highlights
With the rapid development of the national economy, in order to promote further economic development, promote cultural exchanges, strengthen national unity, reduce regional differences, and consolidate national defense, the transportation industry has been vigorously developed, and modern transportation networks have been established in all parts of the country [1]
Bridge structure dynamic load test to determine the dynamic performance of the structure of the bridge, the performance is important symbol, the bearing capacity of bridge operation state, and it is the basic principle of structural damage will cause the system mass or stiffness change, resulting in the change of the model parameters, so it can be through the change of the model parameters to determine, evaluate structural damage [3]
According to the actual situation of Qixiashan Lead-zinc mine in Nanjing, the 7th layer of stope 1015 interrupted by −425 is taken as an example
Summary
With the rapid development of the national economy, in order to promote further economic development, promote cultural exchanges, strengthen national unity, reduce regional differences, and consolidate national defense, the transportation industry has been vigorously developed, and modern transportation networks have been established in all parts of the country [1]. Vibration signal processing and measurement plays an important role in monitoring the rotational machineries in the industrial applications. It is desirable for monitoring the conditions, fulfilling the maintenance requirements, fault prognosis and diagnosis in several industrial processes. The object recognition and tracking systems have been used to achieve high measurement performance while maintain a tradeoff with the computational complexity [10, 11] It is suggested in various recent works that for the evaluation of bridge structures, it is necessary to analyze the static load test as well as action load tests for dynamic structure estimation. In order to carry out a comprehensive detection and evaluation of the bridge structure, this work utilizes static load test on the structure, and in-action load test on the structure, identify the dynamic parameters of the structure, and verify the actual running state of the structure from multiple angles
