摘要
滑坡带来危害巨大,加之滑坡其周围环境较为复杂,对电子设备的性能要求较高。为了提高滑坡监测系统及其节点的稳定性和可靠性,须通过分析在滑坡监测节点周围区域的电磁环境,找出监测节点的干扰源和传播途径,根据实际情况,对电磁干扰的因素进行分析和隔离,从监测节点硬件及相关软件进行电磁兼容设计。最后经EMC测试,保证节点电路电磁兼容的可靠性,确保节点数据的完整性和准确性,从而得到了较高精度的节点数据,达到了良好的电磁兼容性能。
Landslides cause great harm,and landslides have relatively complex surrounding environments and require high performance for electronic equipment.In order to improve the stability and reliability of the landslide monitoring system and its nodes,it is necessary to analyze the electromagnetic environment around the landslide monitoring nodes to find out the interference sources and propagation paths of the monitoring nodes.According to the actual situation,the electromagnetic interference factors are analyzed.And isolation,electromagnetic compatibility design from monitoring node hardware and related software.Finally,the EMC test ensures the reliability of the electromagnetic compatibility of the node circuit,ensures the integrity and accuracy of the node data,and thus obtains higher-precision node data and achieves good electromagnetic compatibility performance.
