Embodiment Construction
[0048] The present invention will be further described below.
[0049] Such as figure 1 As shown, a wireless sensor network detection method for underground pipe gallery, the specific steps are as follows:
[0050] Step 1: Set up converging nodes and n common nodes in the underground pipe gallery. Common nodes are divided into gas sensors (hydrogen sulfide gas sensors are used in this embodiment), pressure sensors, temperature and humidity sensors and smoke sensors. The sink node is the base station for sending, receiving and processing data, and it is located in the center of the underground pipe gallery.
[0051] Traverse all surviving common nodes in the wireless sensor network. Determine the number of neighbor nodes for each common node. If an ordinary node is located within the transmission range of another ordinary node, the two nodes are their respective neighbor nodes. Measure the time required for each ordinary node to transmit data to all its corresponding neigh...
