摘　　要：为使原本用于人工地震测深野外数据采集的PDS型地震仪能够适用于超密集流动台阵野外观测,设计了一种基于Apollo2微控制器的具备GNSS校钟同步和仪器工作参数动态设置功能的外置即插即用式自动控制装置。经室内测试运行和野外比对测试实验,该装置运行稳定可靠,能满足野外超密集台阵长期连续工作的需要。In recent years,as well as being used in deep seismic sounding,PDS seismographs are also used in ultra-dense seismic array observations and ambient noise imaging.Unfortunately,while PDS seismographs have no real-time GNSS time synchronization service,it is critical to get seismic data with high-accuracy sampling time.This paper introduces the hardware and firmware design of a new GNSS-synchronized automatic device based on microcontroller Apollo2.Through laboratory testing and field experiments,this time synchronization and automatic control device for PDS seismographs can well meet the needs of ultra-dense seismic array observations.
