The invention relates to the seismic prospecting technology field, especially relates to a shot point coordinate acquisition system and a shot point coordinate acquisition method used for seismic prospecting. The shot point coordinate acquisition method comprises steps that coordinates of two base point positions are acquired, and sounds at preset frequencies are transmitted to a shaft mouth acoustooptic identification device by the sounding modules of the two base point positions, and then two optical lens modules respond to optical signals corresponding to the sounds at the preset frequencies transmitted by the shaft mouth identification devices; a control and data processing module is used to acquire sounding time and responding time, and then distances between the two base points and a target shaft mouth position are acquired, and at last, the coordinate of the target shaft mouth position is acquired according to the coordinates of the two base points and the distances between the two base points and the target shaft mouth position. By adopting the shot point coordinate acquisition method provided by the invention, the coordinate of the target shaft mouth position is acquired in a sight distance range accurately and remotely in a real-time manner, and therefore the operation efficiency of acquiring the coordinate of the shaft mouth position is improved, and at the same time, personal risks during a shot hole construction process are greatly reduced.
Description
technical field [0001] The present application relates to the technical field of seismic exploration, in particular to a shot point coordinate acquisition system and acquisition method in seismic exploration. Background technique [0002] In the seismic exploration construction of complex terrain such as mountains, the actual position of the shot point often deviates from the pre-designed shot point position. Therefore, it is often necessary to collect the actual shot point position coordinates to confirm whether the drilling position is in compliance with the requirements before seismic excitation. construction design requirements. [0003] At present, most of the coordinates of the actual shot point position are collected by manually carrying the positioning device to the scene. However, this method is inefficient, and on-site coordinate collection in such complex terrain also increases the safety risk of construction personnel. Contents of the invention [0004] Embod...
