Virtual positioning method of metallurgical railway transport vehicle based on RFID

Abstract

The invention discloses a virtual positioning method for metallurgical railway transport vehicles based on RFID, which is aimed at the positioning of the second vehicle at the rear of the locomotive. The logical analysis and judgment of the locomotive operation plan realizes the positioning of the second vehicle; the steps are: first, the dispatcher prepares the locomotive operation plan in the railway area management information system; second, issues the operation plan to the locomotive; The plan is uploaded to the centralized management and control system; third, the centralized management and control system judges the information of the second vehicle in the locomotive operation plan; if the second vehicle is a "trailer" instruction, the second vehicle will run together with the locomotive and the first vehicle, The positions of the locomotive and the first vehicle are the positions of the second vehicle; if the second vehicle is commanded to "take off the vehicle", it is determined that the second vehicle has been decoupled from the locomotive, and the second vehicle arrives at the destination and is unbound from the locomotive .

Description

technical field [0001] The invention relates to an accurate and real-time positioning method for locomotives and vehicles in a metallurgical railway system, in particular to an RFID-based positioning method for metallurgical railway transport vehicles. Background technique [0002] The production and transportation organization of railways in metallurgical enterprises is under the unified command of the dispatcher. The dispatcher compiles the production and transportation plan according to the iron-making and steel-making production plan, the work progress of the station, and the location information of the railway vehicles. The data transmission is sent to the locomotive driver, and the locomotive driver completes the job task according to the job instruction. [0003] The location information of the railway vehicle is an important basis for the dispatcher to prepare the production and transportation plan. After the production and transportation plan is released, the dispat...

Problems solved by technology

[0006] The railway vehicle itself does not have a power system. The power used by the GPS positioning module and the communication system needs to be provided by batteries. Since the railway vehicles are used online 24 hours a day, uninterrupted positioning of the railway vehicles is required, and the power supply capacity of the battery cannot guarantee the GPS positioning module. , The normal use of the communication system, the battery needs to be replaced irregularly

With the passage of time, the replacement cycle of the battery is gradually shortened, and the workload of battery replacement and charging increases sharply. The demand for the battery cannot be guaranteed, and the positioning of the railway vehicle will be wrong.

Railway vehicles are always used in high temperature and dust environment. High temperature will accelerate the aging of batteries. Dust will cause short circuit of batteries, which seriously affects the service life of batteries and greatly increases the maintenance cost of batteries.

[0007] The metallurgical enterprise process railway has a line spacing of only 5 meters, and there are a large number of crossing lines, and there are many workshops. The steel structure of the workshop has serious interference to the GPS signal. In addition, the accuracy of the GPS positioning system is low. In the process of positioning There will be inaccurate positioning, which will cause errors in the vehicle location information on the scheduling screen, which will seriously affect the on-site production scheduling operations
