Method and device for location correction and stolen judgment of smart iron shoes

Abstract

The invention discloses a positioning correction and stolen determination method of intelligent iron shoes. The positioning deviation correction and stolen determination method is divided into system initialization, intelligent iron shoe stolen determination, intelligent iron shoe static positioning anti-drift processing, intelligent iron shoe There are four steps for static positioning and deviation correction of iron shoes. The smart iron shoe stolen judgment algorithm of the present invention improves the identification accuracy of the smart iron shoe stolen layer by layer, realizes the fast and accurate judgment of the stolen state of the smart iron shoe, and can effectively reduce the calculation of the smart iron shoe when performing the stolen judgment. amount, so as to achieve the purpose of reducing energy consumption; the static correction algorithm of smart iron shoes maps the positioning coordinates of smart iron shoes to the track where they are placed, thereby reducing the impact of GPS positioning errors on the status display of smart iron shoes. It is suitable for the judgment of the stolen state and the correction of its positioning information after the application of smart iron shoes in the railway station, which greatly improves the safety of the station and reduces the management pressure of the station personnel.

Description

technical field [0001] The invention relates to the technical field of railways, and is especially suitable for realizing the real-time monitoring of the stolen state of railway intelligent iron shoes and the correction of the static positioning error of intelligent iron shoes, specifically a positioning correction and stolen judgment of intelligent iron shoes method. Background technique [0002] With the increase of railway lines and wider coverage areas, the application of smart iron shoes is becoming more and more extensive, and smart iron shoes have become an important equipment for protecting the safety of personnel and vehicles. [0003] Traditional smart iron shoes have the following problems: smart iron shoes mainly detect the status of uploading and placing them in place, and have a single function; some only rely on detecting the distance between the iron shoes and the train hub or the distance obtained by the second integration of acceleration data to judge theft...

AI Technical Summary

Problems solved by technology

[0003] Traditional smart iron shoes have the following problems: smart iron shoes mainly detect the status of uploading and placing them in place, and have a single function; some only rely on detecting the distance between the iron shoes and the train hub or the distance obtained by the second integration of acceleration data to judge theft, and the distance calculation error Large, the recognition rate of the stolen state of the smart iron shoes is low, which may easily cause the loss or theft of the smart iron shoes, resulting in certain economic losses and security risks; when the smart iron shoes are stationary, the positioning signal will continuously jump due to positioning drift ;In the position calibration of smart iron shoes, because the GPS positioning is greatly affected by various factors such as the environment, there may be certain errors in the position calibration

[0004] Smart iron shoes mainly determine the location through GPS positioning information, so the positioning drift problem of GPS positioning will affect the correct positioning data of smart iron shoes, so that there is a certain deviation between the positioning data obtained by smart iron shoes and the real value, and even smart iron shoes The shoe received wrong positioning data, causing confusion in the management of smart iron shoes
