Wireless sensor node with hierarchical protection structure
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 invention can be deployed by ejection, is highly adaptive to catastrophes, can acquire environmental information effectively, and has relatively low costs.
