Research on Event-Based Updating of Spatial-Temporal Information of Multi-Source Sensor

Event-based information update plays an important role in the construction of smart cities. In this paper, we use the multi-source sensor data as the source. By analyzing the characteristics of different types of events, the updating rules library for the information of emergency events is established to realize the automatic updating of abnormal changes or unexpected events. Based on this, an event update based on the environment temperature change was implemented.
