%X 介绍一种完全自主开发的体积小的基于MEMS无线数字地震检波器。该检波器主要包括以下几个部分：MEMS传感器板、放大采集板、FPGA控制主板、无线触发接收板、无线WIFI模块板和供电电源设计等。该传感器的设计涉及多个关键技术点，包括微弱信号获取、低功耗设计、总体结构的合理布置、高精度和高灵敏度、无线数据通讯以及无线触发信号接收等。应对这些关键技术点，本设计首先对芯片和材料精挑细选、对电路和结构进行合理设计，满足该检波器各项技术指标。最后通过一系列的室内测试和野外试验，验证了该检波器的各项功能和性能，为地震勘探提供高精度、高灵敏度、稳定可靠的地震检波器。<br>This paper presents the development of a compact, independently developed, MEMS-based wire-less digital seismometer. The seismometer primarily comprises several key components: the MEMS sensor board, amplification and acquisition board, FPGA control board, wireless trigger receiver board, WIFI module board, and power supply design. The design of this sensor involves addressing multiple critical technical points, including weak signal acquisition, low power consumption design, rational overall structural layout, high precision and sensitivity, wireless data communication, and wireless trigger signal reception.To address these critical technical points, the design carefully selects the appropriate chips and materials and reasonably designs the circuitry and structure to meet the various technical specifications of the seismometer. A series of indoor tests and field experiments were conducted to verify the functions and performance of the seismometer, providing a high-precision, high-sensitivity, stable, and reliable seismometer for seismic exploration.
