Problems solved by technology
Linear bridge cascading also has certain risks. If a bridge device in the middle fails during system operation, all subsequent bridges will lose connection, and the relevant anchor nodes will also lose their positioning. The connection of the center loses the role of accident warning
In addition, depending on the tunnel excavation process, in the scenario of multiple parallel pilot tunnels, if the network bridge is only deployed in one pilot tunnel, there will be a problem that the signal of the anchor nodes far away from the pilot tunnel is not good; Deploying network bridges in the pilot tunnel will increase the cost of deployment and the complexity of the system

Embodiment Construction
[0027] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] refer to Figure 1 to Figure 3 An embodiment of the tunnel positioning anchor node network and deployment method based on Mesh technology of the present invention is proposed:
[0029] A tunnel positioning anchor node network and deployment method based on Mesh technology, including a core gateway and three anchor node groups.
[0030] The anchor node group consists of multiple anchor nodes in a single pilot tunnel, where the anchor node at the entrance of the pilot tunnel is the root anchor node, and the rest of the anchor nodes are node anchor nodes. The anchor node includes Mesh module, ranging module and power supply.
[0031] When the anchor node is configured as the root anchor node, the Mesh module of the root anchor node is used to establish a Mesh network belonging to the pilot tunnel, and connect th...

The invention discloses a tunnel positioning anchor node network based on a Mesh technology and a deployment method. The tunnel positioning anchor node network based on the Mesh technology comprises acore gateway and at least one anchor node group. The anchor node group is composed of one or more anchor nodes in a single tunnel or a single pilot tunnel, a Mesh network which belongs to the pilot tunnel or the tunnel and has an exclusive identifier is established in each anchor node group, and the anchor nodes in the anchor node groups are sequentially arranged in each tunnel by taking the opening of the tunnel or the starting point of the pilot tunnel as the starting point; the anchor nodes arranged at a tunnel portal or a pilot tunnel starting point in the anchor node groups are root anchor nodes, and the rest anchor nodes in the groups are node anchor nodes; the node anchor nodes are used for connecting the node anchor nodes in front of and behind the node anchor nodes, and the rootanchor node is used for connecting the first node anchor node and the core gateway.
Description
technical field [0001] The invention relates to the field of tunnel construction, in particular to a Mesh technology-based tunnel positioning anchor node network and a deployment method. Background technique [0002] In the field of tunnel construction, the positioning system in the tunnel is an important system to solve the specific location of the operator, pre-warning and post-event search and rescue, and strive for rescue time. At present, most accurate personnel positioning systems mostly adopt the method of wearing a tag on the operator, and then performing TOF or TDOA distance measurement between the tag and the anchor node of the known position to determine the position result of the personnel. After each anchor node communicates with the tag, the measurement results are collected to the positioning center, and the positioning center combines the map of the tunnel to finally determine the position of the tag in the tunnel. [0003] How to deploy anchor nodes in the ...
