Sensor Review, Volume 35, Issue 1, January 2015.
Purpose The purpose of this paper is to propose a new method to achieve omni-directional vibration vector signal acquisition, and use this method to improve the accuracy of the underground explosion point localization. Design/methodology/approach Following an introduction, this paper describes the design principle of sensor structure, and discusses the rationality of the spherical structure of the sensor through the finite element analysis. The sensor prototype is designed according to the above method, and the performance of which is tested by sensor calibration experiment. Finally, applications are also discussed. Findings This shows that the method for underground omnidirectional vibration signal acquisition is reasonable and feasible. The vibration sensor, designed by this method, of which the triaxial dynamic characteristics are consistent, and three-dimensional vibration information acquired by this sensor can achieve high-precision localization for underground explosion point. Originality/value The paper describes a new method for omnidirectional vibration vector signal acquisition. The vibration sensor is developed based on this method, which has a broad application prospect in the position of underground explosion point, the evaluation explosive power and other underground projects.
