Design and Implementation of multi-dimensional History Playback System Based on IoT Data

In the Internet of Things(IoT) monitoring system, there are various devices for monitoring the target's movement trajectory and behavior, the raw data of these devices has accumulated over time to form huge historical data. A historical review of monitoring targets requires a system that presents the target's historical data in a visual form. The existing system has realized the storage of target historical data, but there is still a lack in the playback of historical data. The system lacks the visual playback of the target multi-device historical monitoring data, that is difficult to comprehensively reflect the behavior information and movement status of the target during the playback period. The system lacks dynamic presentation of the target's historical motion trajectory, that is difficult to visually display the target's historical position at different times during playback, and it is impossible to analyze the historical behavior trend of the target. This paper designs and implements a historical data playback system that supports the display of target multi-dimensional information and the dynamic presentation of target track to solve the above problems. A lightweight web application framework Express is used to build a website. Based on GIS(Geographic Information System) technology, an incremental update method for fast and dynamic rendering of the target track is proposed. Combined with the component technology, the target history multidimensional information visualization is presented. Test results show that the system can complete multi-dimensional playback of historical IoT monitoring data and rapid dynamic presentation of target tracks.
