Abstract:

This study analyzes the present technologies related to environment sensing and intelligent crisis response, and integrates Virtual Reality (VR) and Internet of Things (IoT) technologies to implement a real-time geographical environment monitoring system aimed at solving the real-time monitoring and intelligent reaction needs of the ecological monitoring and protection of a remote island. The system adopts Browser/Server (B/S) architecture that contains four layers, a sensor layer, network layer, service layer, and application layer, forming complete technical processes beginning with data perception, data transmission, and data computation and finalizing in data application. Tables are designed according to environmental monitoring sensors that are mainly utilized in the water, soil, meteorology, and vegetation monitoring, thus achieving a unified storage and management system of multi-source heterogeneous sensor data. IoT technology is adopted to connect the sensors, servers, and computers into a unified network that achieves wireless transmission and both the access and remote storage of geographical environment data (e.g. water, soil, air and biology) from which the dynamic changes of water quality in the harbor, soil drought in the thicket, and meteorology in the island area can be displayed and evaluated; in this manner an early warning for abnormal changes in the environment can be obtained. VR technology is used to navigate and perform operations in both the indoor and outdoor modeled and integrated island scenery. Moreover, by integrating VR and IoT technologies, remote control of the intelligent sensing device is achieved; for example, this control is applicable for vegetation watering valves and lights. Using this system, a manager can not only obtain real-time geographical environment data and identify any abnormal changes of environmental features, but also remotely control intelligent sensing devices. Consequently, manual management of the island is no longer needed, and working efficiency is improved.
