An intelligent dispatching system for railway transportation logistics and its vehicle position tracking method

Abstract

The invention relates to an intelligent railway transport logistics dispatching system and a locomotive location tracking method thereof. The intelligent railway transport logistics dispatching system and the locomotive location tracking method thereof are realized through an industrial railway locomotive location tracking algorithm via software. The industrial railway locomotive location tracking algorithm is achieved in a logistics management server. The overall functionality is achieved through a locomotive location tracking module, an information removal processing module and the like which are included in the system. An intelligent dispatching computer, a logistics management computer, a logistics management server, a logistics management database, an ERP (Enterprise Resource Planning) interface database, a locomotive number identification system and other computers and servers are communicated through Ethernet. The intelligent dispatching computer and a signal system computer are in an RS232 communication. The intelligent dispatching computer is communicated with a railway locomotive security control system through an industrial wireless network. The intelligent railway transport logistics dispatching system and the locomotive location tracking method thereof can track the locomotive location in the process of the industrial railway transport.

Description

technical field [0001] The invention relates to various theories and technologies such as computer technology, network and communication, database, logistics tracking, etc., and is mainly applied to the vehicle position tracking of the intelligent dispatching system of industrial railway transportation logistics. Background technique [0002] At present, the transportation volume of goods in key industries such as metallurgy, petrochemicals, coal mines, ports, and wharves in my country is very large. These enterprises generally have a large number of self-owned railway stations. Railway transportation is an important form of internal transportation for these large enterprises. [0003] In the industrial railway transportation within the enterprise, the vehicle location information is the basis of its transportation organization and scheduling. Only when the location information of all vehicles in the enterprise station is grasped accurately and in time can the transportation...

AI Technical Summary

Problems solved by technology

Due to human negligence and misoperation, it is often impossible to accurately grasp the logistics information of the station in real time, which brings difficulties to the next step of operation, and even prevents the entire operation from proceeding smoothly. Serious consequences came, which directly affected the company's benefits

With the continuous expansion of the production scale of industrial and mining enterprises, the task of railway transportation is becoming more and more arduous. Accurate management of these huge logistics information

[0005] Some of the current railway vehicle position tracking technologies have certain problems and are not suitable for promotion in enterprises. For example, the first is to use the track circuit method to detect whether there is a vehicle on the track by detecting the short circuit between the tracks caused by the wheels.

But this method can only detect whether the track is occupied by vehicles, but cannot detect the number of vehicles and which one or several vehicles; the second is to use the GPS global positioning system to install GPS receivers on each vehicle. The system and the wireless communication system send the positioning information detected by the GPS to the dispatching room through the wireless communication system, and then calculate its orbit through the GIS system

For a larger enterprise with thousands of vehicles, this method requires a large investment, and the power supply problem of the vehicle equipment is difficult to maintain; the positioning accuracy of GPS for civilian use is not accurate enough, and GPS is greatly affected by the weather and surrounding buildings, which is prone to errors In addition, this method cannot locate the non-enterprise vehicles entering the enterprise from the road bureau; the third is to install an automatic vehicle number identification system developed by radio frequency identification technology: install RFID electronic tags on each vehicle, and in all Automatic vehicle number identification system is installed at both ends of the parking line

The investment in this method is huge, and it is difficult for ordinary enterprises to bear
