Abstract

The invention provides a wireless transmission node, a control method thereof and a wireless ad hoc network transmission system, and relates to the field of wireless communication. The wireless transmission node provided by the invention has a bidirectional linear routing rule set, so that the quality of communication links between the wireless transmission node and boundary wireless controllers on two sides can be determined; in addition, according to the method, one end with higher quality is selected as the communication link of the main route, and the communication link of the standby route can be automatically switched to after the quality of the communication link with the main route fails to be reduced to the preset threshold value, so that the data transmission reliability and efficiency of the nodes in the network are improved. Meanwhile, the wireless ad hoc network transmission system is constructed on the basis of an upper computer, at least two boundary wireless controllers and the wireless transmission nodes, and is provided with double communication home nodes, so that bidirectional strategy selection of routing, networking, network maintenance, and network faults and the like is realized, hops experienced by original tail end nodes are reduced; therefore, the data transmission reliability and efficiency of the linear topology wireless ad hoc network are obviously improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, more specifically, to a wireless transmission node, a control method thereof, and a wireless ad hoc network transmission system. Background technique [0002] Railway engineering, locomotive, and transportation departments, in consideration of safety and scheduling, need to collect and transmit data from equipment along the line, such as lines, wind, rain, snow, tunnels, bridges, and other facilities. Due to the limited power supply conditions of its intervals and poor network communication, the existing technical solutions mostly use chain network communication systems or linear topology wireless ad hoc network system solutions. [0003] The above two schemes both initiate a networking request through a single master node in the network, and extend the network coverage to the end nodes step by step. Due to the lack of redundant nodes and backup links, etc., after any node in the net...
