以厦门地震勘测研究中心信息节点为例，阐述了福建省地震行业网内信息节点设备运行中存在的储多安全隐患，讲述如何应用信息节点设备中的交换安全技术来消除福建省地震行业网内的信息安全隐患，来提高地震信息节点设备的网络连通率及稳定性，保障地震行业网内观测数据的可靠与高效运行。

Take the Xiamen Research Center of Seismic Exploration as an example, we describe the potential safety hazard which exist in the information nodes equipment of seismological industry network of FujianProvince. We state how to apply the security exchange technology for information nodes to eliminate the hidden danger in the earthquake network, and to improve the stability and connectivity rate of the network, thus guarantee the security and high efficiency operation of the observable data in the seismological industry network.
