Abstract
A sonar-integrated IoT device, the IoT device including one or more sonar sensor modules (), corresponding to information acquisition in different spatial directions; the IoT device is in communication connection with an external signal processing unit through a wireless network, and sends unprocessed or preliminarily processed spatial information to the signal processing unit. The advantages of the invention include: simple and flexible arrangement of sonar sensor module () nodes, which are integrated with wireless IoT devices such that spatial information may be acquired locally; and at the same time, ease of implementation of large interval arrangement and large quantity arrangement of sonar sensor modules (), covering a variety of spatial locations, thereby providing wide coverage of spatial detection range, and acquisition of abundant signal samples, such that better spatial information extraction algorithms may be implemented in the signal processing unit.
