Abstract

The invention is suitable for the field of positioning technology, and provides a positioning method and a positioning system for a rescue cabin robot. The method comprises the following steps: acquiring a plurality of groups global positioning data of the rescue cabin robot by a plurality of wireless positioning terminals through measurement at a plurality of equal time intervals; acquiring localpositioning data of the rescue cabin robot through measurement at a plurality of equal distance intervals; acquiring instantaneous attitude information and instantaneous environment information of the rescue cabin robot; performing weighted data fusion on the global positioning data, the local positioning data, the instantaneous attitude information and the instantaneous environment information through a prebuilt weight function; and acquiring precise position coordinates of the rescue cabin robot through a pre-established algorithm. The positioning method has the advantages of small interference error, high positioning precision, high convergence speed and high stability. The downhole operation safety is enhanced, and the survival probability of rescued personnel is increased.

Description

technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to a positioning method and a positioning system for an emergency cabin robot. Background technique [0002] With the rapid development of wireless communication technology and network technology, various new technologies and new applications are constantly changing our work and life, especially with the mature development of ground wireless positioning and network technology, driving underground positioning technology and Development of network communication. However, the complex underground environment and narrow space have caused great limitations to the installation and use of network wiring and equipment, and the wireless signal fades rapidly during the transmission process in the roadway, and there are a lot of reflection, scattering and diffraction phenomena. Vehicle mobility, Large aggregation also has a certain impact on the transmission of wireless signals...
