Urban rail train positioning system and method based on LORA messages

Abstract

The invention provides an urban rail train positioning system and method based on LORA messages. The urban rail train positioning system based on the LORA message comprises a control center, an LORA information label module, a display module, a power supply module, an alarm module, a monitoring module and a speed measurement module; the control center comprises a computer and a storage unit, and the computer and the storage unit are both installed in the control center. The computer controls the operation of the LORA information label module, the display module, the power supply module, the alarm module and the monitoring module, the storage unit stores various urban rail train information in the computer, the LORA information label module comprises an LORA signal transmitter and an LORA signal receiver, the LORA information label module records basic information of an urban rail train. The LORA signal transmitter is installed on an urban rail train. The urban rail train positioning system based on the LORA message and the method thereof provided by the invention have the advantages that the installation of wireless radio frequency equipment is reduced, the cost is saved, and the power consumption is reduced.

Description

technical field [0001] The invention relates to the field of positioning systems for urban rail trains, in particular to a positioning system for urban rail trains based on LORA messages and a method thereof. Background technique [0002] Urban rail transit system refers to the traffic system that uses vehicles to run on fixed guide rails in cities and is mainly used for urban passenger transport. In urban rail transit, the operation of trains mainly depends on the signal system, which is to ensure the safety of line transportation and improve transportation efficiency. It is an important system for improving working conditions and can realize functions such as train safety interval control, precise positioning and fixed-point parking. [0003] The first commonly used is RFID technology to locate urban rail trains, radio frequency identification, RFID technology, also known as radio frequency identification, is a communication technology, commonly known as electronic tags. ...

AI Technical Summary

Problems solved by technology

[0004] In the urban rail train positioning system implemented by RFID technology, the wireless transmission distance is relatively short, and more radio frequency equipment needs to be installed, and its power consumption is also large, resulting in high cost.
