Smart IoT cable well
As part of the function of the power distribution cloud master station, the system module realizes the intelligent monitoring of cables and channels, gradually replaces manual inspections, and improves the quality and efficiency of operation and maintenance management. The system adopts a typical Internet of Things architecture system construction mainly including application layer, platform layer, communication layer, convergence layer, terminal layer. Application layer: including anti-theft alarm, cable online monitoring, intelligent inspection, statistics, alarm management, emergency repair management and other functions. Platform layer: It consists of centralized deployment of server nodes or cloud platforms. Communication layer: use wireless communication to establish data flow control, re-centralize and re-manage business data based on the decentralized information system, realize the storage and update of interactive process data, and perform effective utilization and analysis of collected measurement data and associated data for Various application functions of the system provide support. Convergence layer: The main cable well monitoring edge computing terminal is realized, including the collection and analysis of sensor data and the functions of data compression, protocol conversion, fault judgment, data analysis, etc., and the realization of in-situ calculations for some functional applications. Terminal layer: Various types of miniaturized, low-power sensors are used to collect environmental and status data, including environmental information such as the temperature, humidity, toxic and harmful gas concentration, manhole cover displacement, and cable connector temperature in the cable well. Intelligent operation and maintenance of power distribution cables.
