摘要
针对我国城市地震烈度速报系统需要大量布置地震数据采集点的实际情况,提出以ARM作为微处理器,控制模数转换芯片转换由MEMS加速度计采集的振动信号,并通过以太网进行数据传输的强震动数据采集方案,获得的信号符合地震观测数据采集相关要求。
In China, the Urban Seism Intensity Rapid Report System （USIRRS） needs a lot of collected sta- tions to acquisition seismic data. We propose a scheme that the ARM microprocessor as the controller, controlling the ADC converting the signal which the MEMS accelerometer collected, and transmitting the macro-seism data by Ethernet. The data of the seismic signal acquisition complied with the relevant requirements of the macro-seism data acquisition.
