Positioning, deviation correcting and theft judging method of intelligent iron shoe

Abstract

The invention discloses a positioning, deviation correcting and theft judging method of an intelligent iron shoe. The positioning, deviation correcting and theft judging method comprises four steps ofsystem initialization, intelligent iron shoe theft judgment, intelligent iron shoe static positioning anti-drift treatment and intelligent iron shoe static positioning deviation correcting. Accordingto the intelligent iron shoe theft judgment algorithm, the intelligent iron shoe theft identification precision is improved layer by layer, the intelligent iron shoe theft state is judged quickly andaccurately, and the calculation amount of the intelligent iron shoe during theft judgment can be effectively reduced, so that the purpose of reducing energy consumption is achieved; the intelligent iron shoe static deviation correction algorithm maps the intelligent iron shoe positioning coordinates to the tracks on which the intelligent iron shoe is placed, so that the influence of GPS positioning errors on intelligent iron shoe state display is reduced. The positioning, deviation correcting and theft judging method of the intelligent iron shoe is suitable for judging the theft state of a railway station and correcting the deviation of the positioning information of the railway station after the intelligent iron shoe is applied to the railway station, which greatly improves the safety ofthe station and relieves the management pressure of personnel in the station.

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
