Abstract

The present invention discloses a wireless sensor node with a hierarchical protection structure, including a node hardware circuit and a node hierarchical protection structure. The node hardware circuit includes a sensor module, a data processor module and a wireless communication module, and the node hierarchical protection structure includes a primary sealed protection structure and a secondary strengthened protection structure; the primary sealed protection structure includes an ABS spherical inner shell; the data processor module and the wireless communication module are disposed in the ABS spherical inner shell; gaps in the ABS spherical inner shell are filled with EPE cushioning foam; a flame-retardant and thermal-insulating layer made of a nanometer aerogel insulation blanket is covered on the outside of the ABS spherical inner shell; the secondary strengthened protection structure includes a spherical nylon outer shell with vent holes; the spherical nylon outer shell and the ABS spherical inner shell are connected with each other through support of rubber dampers; and the sensor module is disposed in the spherical nylon outer shell. The node according to the present inventi…
