【摘要】 地震动数据采集系统的任务是通过前端传感系统检测环境中的各类物理信号如声、震动、磁信号等,并对获得的数据进行实时处理,以确定环境中地下目标对象的信息,如位置和加速度等。本系统将地震动传感器(阵列)、信号调理电路、A/D转换模块、无线收发模块、GPS模块、控制电路、通讯接口及电源模块紧凑在一起,构成一种既可独立工作又能协同工作的便携式地震动信号测试仪。该系统具有抗干扰性强、无线控制、微功耗等优点,特别适宜于大范围多测点的地震动测试试验场合。更多还原

【Abstract】 The mission of the ground motion data collection system is described as through front sensor system detects all types of physical environments signal such as acoustic,seismic,magnetic signals and so on.Then processed the received signals to determine the underground target environment information such as location,the acceleration and so on.The system combined ground motion senso(rarray),signal conditioning circuit and A/D conversion module,wireless transceiver,GPS module,control circuit,communication interface and power module together and constituted a kind of portable seismic signal tester which can work independently and cooperatively.The system is featured by strong anti-interference,wireless control and micro power consumption etc,especially suitable for a wide range of multipoint ground motion test situation.更多还原
