Abstract For the purpose of improving the reliability of secondary operation security measures, this paper proposes a three-layer architecture of “perception-collection-application”, develops four types of Internet of Things (IoT) intelligent security measures tools, selects multi-mode anti-interference gateways, and constructs a full-process control platform for security measures. The engineering practice of a 220 kV substation shows that the arrangement time of safety measures is shortened by 45.2%, the misoperation rate is reduced to 0, and the leakage recovery rate is eliminated by 100% closed-loop. The new secondary operation safety measure technology realizes the transformation of safety measure execution from “passive protection” to “active early warning” and management from “post-event verification” to “process interruption”, which significantly improves the intrinsic safety level and operation and maintenance efficiency of secondary operation, and has important engineering application value.

Key words： safety measures Internet of Things (IoT) sensing intelligent control real-time monitoring active warning
