Embodiment Construction

[0041] The present invention will be described in detail below in combination with specific real-time methods; it should be understood that the implementation examples are only for illustrating the present invention and should not be regarded as limiting the scope of the present invention.

[0042] figure 1 It is a block diagram of the distribution of base stations and sensor nodes in the coal mine.

[0043] Such as figure 1 Shown is the distribution map of multiple underground tunnels. Each tunnel has a base station to receive monitoring data and transmit the data to the monitoring center on the ground through the CAN bus; the beacon node broadcasts data according to its own location information. After positioning, it is responsible for transmitting the received monitoring data to the beacon node or base station of the next hop; the node to be tested is positioned according to the hop distance from itself to the beacon node, and when there is monitoring data transmission, it...

Abstract

The invention discloses a positioning and routing method based on a DV-Hop (Distance Vector-Hop) positioning mechanism, and the positioning and routing method is applied to downhole special environments. According to the method, beacon nodes are manually arranged according to the special environment of a downhole tunnel; during positioning, the characteristic that the transmitting power of downhole sensor nodes is low is utilized, the transmitting power of the beacon nodes is reduced, and the positioning accuracy is improved; and after completing positioning, the transmission of monitoring data is realized in an assisting manner according to network hop routing information recorded by the nodes during the positioning.

Description

technical field [0001] The invention relates to a WSN positioning algorithm DV-Hop without ranging, and uses positioning information to realize routing transmission of monitoring data. It is applied to underground safety monitoring of coal mines, and uses the special distribution of beacon nodes and small underground transmission power to realize nodes. precise positioning. Background technique [0002] The wireless sensor network refers to a network composed of a large number of low-cost sensor nodes through wireless transmission. The difference between it and the traditional network is that it can realize real-time interaction with the surrounding environment through sensors and actuators. The sensor network has many advantages such as large coverage area brought by distributed processing, high precision monitoring, high fault tolerance, remote monitoring, etc., and has become one of the important hotspots of recent international network research. [0003] A large number ...
