The invention provides a scene fast switching method and device based on an LPWAN. The method comprises the steps of collecting cell user data, establishing a three-layer node allocation model, obtaining a local allocation rule, and allocating the cell user data through the three-layer node allocation model; establishing a data packet total transmission time algorithm, obtaining the allocated celluser data as to-be-calculated data, and calculating the to-be-calculated data according to the data packet total transmission time algorithm; and obtaining the data packet total transmission time , obtaining the scene switching time according to the cell user data, comparing the data packet total transmission time with the scene switching time, generating a corresponding map scene according to acomparison result, and switching the current scene of the user. According to the method, the efficiency of data in the transmission process is improved by establishing the three-layer node allocationmodel and utilizing the data packet total transmission time algorithm, the map can be pre-cached in advance through the algorithm, and the map switching speed of the whole scene is increased.
Description
technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a method and device for quickly switching scenes based on LPWAN. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. As long as the Internet of Things is widely used in the integration of networks through communication perception technologies such as intelligent perception, identification technology, and pervasive computing, more and more places are now using Internet of Things technologies, and the more common ones are smart communities. . [0003] When the existing smart community realizes community scene exchange through the Internet of Things technology, because the scene is different, the amount of data to be transmitted is also different, the response speed is slow, the power consumption required for...
