Abstract

The invention discloses a self-adaption unmanned device moving trail correction method and system. The method includes: step 1, adopting a RSSI (received signal strength indicator) distance measurement algorithm for acquiring a distance between every two adjacent unmanned devices in a polygonal structure formed by at least three unmanned devices; step 2, under an ideal state, the distance betweeneach unmanned device and a mobile base station in the polygonal structure is equal, and calculating the distance between the mobile base station and each unmanned device and angle information of the mobile base station with every two adjacent unmanned devices according to the cosine law under the ideal state; step 3, correcting a moving trail of the mobile base station according to the distance between the mobile base station and each unmanned device and the angle information of the mobile base station with every two adjacent unmanned devices under the ideal state. By the RSSI distance measurement algorithm, the distance of the at least three unmanned devices is positioned accurately, acquisition of position information of the unmanned devices under different environmental conditions can be realized, high measurement accuracy is achieved, and data transmission efficiency through the system is maximized by moving trail correction.

Description

technical field [0001] The invention relates to the technical field of unmanned device control, in particular to a method and system for correcting the running track of an adaptive unmanned device. Background technique [0002] With the continuous maturity of intelligent technology and rising labor costs, the use of automated unmanned devices and robots is becoming more and more widespread. Due to the serious differences in some special occasions, such as nuclear radiation, the use of unmanned devices can reduce the number of unmanned devices in the detection system, and the joint operation of multiple unmanned devices is used. In this teamwork mode of work In order to improve the data transmission efficiency of the whole system, the current method is to add a mobile base station to the detection system based on the unmanned device, and filter useful data through the mobile base station to transmit to the terminal platform so as to pass the data transmission efficiency of th...
