The invention discloses a network ranging method and device. The method comprises the steps of obtaining at least two communication nodes in a communication network, enabling the communication nodes to carry out communication according to a preset communication protocol, and transmitting and receiving a broadband signal through each communication node; obtaining the timestamp of the sending time when each communication node sends the broadband signal and the timestamp of the arrival time when each communication node receives the broadband signal, calculating the propagation time between any two communication nodes according to the obtained timestamp of the sending time and the timestamp of the arrival time, and calculating the relative distance according to the propagation time; obtainingthe timestamp of the arrival time corresponding to each received broadband signal through a monitoring node; calculating the relative propagation time difference of the monitoring node between any twocommunication nodes according to the timestamp of the arrival time corresponding to each broadband signal; and calculating the relative distance difference according to the propagation time difference. According to the method, high-efficiency and high-precision relative distance measurement between the network nodes is realized.
Description
technical field [0001] The invention relates to the technical field of dynamic network ranging, in particular to a network ranging method and device. Background technique [0002] In a dynamic network, it contains multiple nodes. In the communication process, obtaining the distance and relative distance between nodes is of great significance to communication. However, the existing methods, when the number of nodes in the network increases, the demand for broadband signal resources As a result, the update delay of network ranging information will continue to increase, and the efficiency will become lower and lower. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, an object of the present invention is to propose a network distance measurement method, which realizes high-efficiency and high-precision relative distance measurement between dynamic network no...
