无线节点状态QC与资料品质关系研究与应用OA北大核心CSTPCD

With the development of high-density acquisition technology,the size of pattem larger and larger,and the number of wireless acquisition node instrument used for receiving also increases exponentially.The node status quality control method based on WiFi and Bluetooth cannot meet the requirements of completing the node status quality control before daily acquisition.To this end,a quality control technology based on LoRa communication technology and LoRaWAN communication protocol is introduced,and the UAV is equipped with a LoRa gateway to achieve near real-time quality control of the node status.By analyzing the Hy-perQ quality control data of the Quantum node,the three basic information with the highest frequency of abnormal states were de-termined,and the relationship between the node state quality control data and seismic data was deeply discussed,and the method of node replacement in complex operation areas was proposed.We also suggested that the node state quality control method and the seismic data quality control method should be comprehensively applied in the process of wireless node acquisition to jointly monitor the acquisition quality of seismic data.In the swamp area of Project X in South America,based on the principle of node replace-ment,the comprehensive QC techniques were adopted,to increase Class-A single-shot gathers by 9.72％on the premise of control-ling cost.The QC requirements were satisfied,and the quality of newly collected seismic data has been greatly improved.
