IoT products can be freely networked in various modes as required by application scenarios. By relying on automatic control in areas with abnormal network outage and inspection on direct-connected equipment at the site, unattended operation and unmanned deployment are realized. Through configurable business logic and OTA upgrade, all-weather and full-time environmental monitoring and equipment control are realized based on remote judgment by the edge computing module. The products can provide managers with dynamic and multi-dimensional analysis data and accurate decision-making to comprehensively improve safety supervision and management capabilities.
