摘要
自主研发的无线节点仪器eSeis 1. 0,通过GPS训钟技术提高了eSies 1. 0采集系统与激发源的同步精度。高精度32位模数转换模块保证了系统能够采集到保真的地震信号,实时的质控功能弥补了业内众多无线节点"盲采"的短板,低功耗采集站、高性能的锂铁电池、超大的采集站内存保证了节点野外超长的工作时间。与G3i、HAWK等设备的二维试验对比表明,eSies 1. 0采集系统逻辑正确,功能稳定,地震数据资料品质优良。
The wireless node seismic recording system eSeis 1.0 has been developed independently. The synchronization accuracy of eSies 1.0 recording system and the shooting source was improved by using GPS disciplined clock technology. The high fidelity seismic signals were assured by high precision 32 AD conversion module. The real-time quality control was one of the advantages for the wireless node system. The low-power nodes, high performance lithium iron batteries and high-capacity memory card prolonged the working hours in field. The results of 2D test compared with that of G3i and HAWK proved that the eSeis 1.0 system was stable and the seismic data was accurate and perfect.
