摘　　要：针对密集观测中台站实时波形数据汇集的应用需求,提出基于物联网MQTT协议,具备登录安全认证和波形数据传输加密的地震波形实时汇集方案.研发了地震数据采集器中基于MQTT协议的地震波形数据传输软件和云服务端的数据汇集软件.基于云服务器和通用MQTT服务器进行了基于MQTT协议的实时波形数据汇集实验,实验结果表明可利用物联网和云平台实现地震观测数据实时汇集与处理.According to the requirement of massive real-time data transmission in high density seismic network,a seismic wave real-time transmission scheme with login security authentication and waveform data transmission encryption based on the IOT MQTT protocol is proposed.The real-time earthquake waveform transmission software based on the MQTT protocol of the seismic digitizer and the data receiving software running on the cloud server are developed.The real-time waveform data transmission experiments between seismic digitizer and the cloud server based on the MQTT protocol and the EMQTTD server are performed.The experimental results show that the real-time receiving and processing of seismic observation data can be realized by using the IOT and cloud platform.
