This server mainly completes the issuance and service functions of remote control commands from the command center to hangars (indicator lights, doors, main power supply, light switches, etc.).
2.2.2 Composition and Solution
The IoT-based hangar data acquisition service platform implements functions such as data acquisition, protocol conversion, data processing, and visual display for network devices, sensor perception devices, and various control devices within the hangar. It achieves the goals of full digitalization, virtualization, intensification, and intellectualization of hangar facility and equipment management, including automatic acquisition of key operating data (power supply devices, fueling devices, equipment switches, electricity consumption, water consumption), remote real-time monitoring, and intelligent early warning, strengthening real-time supervision of hangar operation status. Through analysis and data mining of various operating data at the hangar site, it provides functions such as real-time operation monitoring, process control, operation simulation, abnormal operation early warning, optimized operation decision-making, and risk analysis for hangar operation management.
A perception layer system is established. The perception layer equipment mainly includes power supply devices, fueling devices, main power supply, oil pumps, oil tanks, fans, online instruments and meters, automatic control systems, and temperature/humidity environment monitoring sensors, which form the foundation of the IoT technology architecture. Through devices such as intelligent IoT gateways, data protocol conversion is implemented, enabling conversion of multiple communication interfaces and protocols, automatic acquisition of operating data from various PLCs and drivers, and establishment of data communication with various PLCs and drivers through IoT protocols, ultimately forming a complete perception layer system.
The perception layer provides a large amount of operating data from equipment, facilities, and IoT sensors. Only by deeply mining the relationships among various data and reasonably utilizing this data can the establishment of the IoT system be meaningful, i.e., the IoT dispatch platform. Firstly, through preliminary processing and display of various data from the perception layer, it achieves over-limit alarming of real-time hangar operating data; secondly, through summary and calculation of production operation data, it generates various charts for daily hangar operation management, facilitating management personnel in summarizing and analyzing daily operation conditions; through in-depth analysis and mining of hangar operating data, it achieves various abnormal early warnings, optimized dispatch analysis, and comprehensive decision-making guiding hangar operation management, as well as equipment analysis, cost analysis, and risk analysis guiding airport comprehensive operation decision-making.
