Embodiment Construction

[0033] The present invention will be further described below by embodiment, and the mode of the present invention includes but not limited to following embodiment.

[0034] The invention makes up for the deficiencies of the inertial navigation system through a stable real-time navigation and positioning system, realizes accurate correction of the indoor positioning system, and ensures the accuracy of positioning. The realization method is: adopt the loose combination mode, use the indirect method to design the state of the polar combination system, and correct it by feedback correction, that is, the error ΔX of the navigation parameter X output by the small positioning unit is used as the main state variable of the filter, and the filter estimates The main part of the value is the navigation parameter error estimate ΔX, and then ΔX is used to correct X.

[0035] Its specific calibration method includes the following steps:

[0036] S1: An integrated navigation system composed...

Abstract

The invention discloses an indoor positioning electromagnetic calibration method for fire rescue. The method mainly comprises the following steps: firstly, adopting an integrated navigation system consisting of an electromagnetic calibration system and an inertial navigation system to establish an inertial navigation error system equation and an electromagnetic calibration error system equation, combining the two equations to obtain a system equation through discretization operation, dynamically correcting each parameter, and substituting the corrected data into a final system equation. According to the invention, a loose combination mode is adopted, an indirect method polarity combination system state design is used, correction is carried out through feedback correction, the error delta Xof a navigation parameter X output by a small positioning unit is used as a main state variable of a filter, the main part of the estimated value of the filter is the estimated value delta X of the navigation parameter error, and then delta X is used for correcting X, so that accurate indoor positioning of firefighters is realized, real-time accurate monitoring of the firefighters is realized, the fire rescue efficiency is improved, and meanwhile, the life safety of the firefighters is ensured.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to an indoor positioning electromagnetic calibration method for fire rescue. Background technique [0002] In the event of emergency events such as fire danger, it is necessary for firefighters to deal with emergencies such as fire danger, and when handling emergency events, in order to ensure the safety of firefighters, it is necessary to monitor the action position of firefighters , and the existing positioning technology in the indoor environment, the inertial navigation system cannot accurately locate for a long time, so a stable real-time navigation and positioning system is urgently needed to make up for the deficiency of the inertial navigation system. The integrated navigation system formed by combining the electromagnetic calibration system and the inertial navigation system can just solve this problem. The inertial navigation system and the electromagnetic calibration...
