A wireless sensor node buffer protection device

Abstract

The invention relates to a wireless sensor node buffering protector, which comprises a spherical shell, wherein the spherical shell is formed by buckling an upper spherical cover and a lower spherical cover together in a welding manner, a frame is arranged in the spherical shell, the frame comprises an upper circular plate and a lower circular plate which are respectively used for fixing wireless sensor nodes, and four square side plates encircling the wireless sensor nodes are symmetrically arranged between the upper circular plate and the lower circular plate; and a plurality of buffering springs are respectively hinged between each of the upper circular plate and the lower circular plate and each of inner walls of the upper spherical cover and the lower spherical cover, and a plurality of buffering springs are respectively hinged between each of the four square side plates and the inner wall of the upper spherical cover. The wireless sensor node buffering protector can be used for effectively solving the problem that the nodes are failed in the throwing process when colliding with the ground, avoiding the situation that the performance of the whole wireless sensing network is influenced as part of nodes are directly failed due to huge image force when being in contact with the ground, and providing an effective guarantee for normal operation of a network and has the advantages of simple structure, safety, reliability and good use effect.

Description

technical field [0001] The invention relates to a buffer protection device, in particular to a buffer protection device suitable for wireless sensor nodes in a wireless sensor network. technical background [0002] In wireless sensor network applications, the initial layout of nodes directly affects the subsequent network coverage. In some cases, it is difficult to artificially deploy nodes accurately, but they are randomly deployed in the desired area through the method of aerial throwing. Due to the lack of buffer protection devices in traditional wireless sensor nodes, the huge impact force generated when they contact the ground during random throwing often leads to direct failure of some nodes, which affects the performance of the entire wireless sensor network. Contents of the invention [0003] Technical problem: The purpose of the present invention is to provide a wireless sensor node buffer protection device with simple structure, good performance, safety and relia...
